DIY fireplace chair. How to make various chairs with your own hands

Using a chair-bed instead of full-fledged separate items furniture relevant for small rooms. Successful combination places for sitting and sleeping allows you to ergonomically organize the space of the room.

Search for space arrangement options small apartment often leads to the idea of ​​buying a folding chair.

Buying such an item may not be profitable. But you can make furniture yourself if you have the skill. How to make a chair bed , many people know who equip their apartments and houses with handmade items.

Advantages of self-production furniture - a bunch of. First, the basics, which are used, can be found at home or in the country, and can also be bought in specialized stores at a price incomparably lower than the finished item.

Blanks made of wood or its derivatives, filler and fabric - this is what you will need, in addition to various types fastenings.

To make a chair bed with your own hands , you will spend 2-3 times less funds. In addition, you can choose your own design designs , coating material and color scheme.

All this allows you to create an original model that is convenient for your home.

Deciding on design and construction

Chair-beds are divided into two main types:

• Frame;
• Frameless.

Intraspecific differences furniture vary based on the choice of shapes and transformation mechanism.

Traditional materials make it a reliable support for long years.

It is more difficult to make a frame model. Furniture with a rigid base is complemented by a layout mechanism, which must be done correctly so that the “liner” can be easily removed and straightened without distortion. A design with two folding legs is easier to make than one with four.

Can be selected as wooden base supports, and metal.

Determine this or that suitable design necessary not only based on the complexity of the creation, but also on its style, safety and convenience for relaxation. For folding chair you can choose theselike chipboard, plywood, textile of a certain density, foam rubber for upholstery, if a frame option is envisaged.

This furniture is compact and ergonomic, noticeably smaller in size standard bed, but is not inferior to it in terms of ease of relaxation.

A product without a rigid base can have a streamlined shape, and it is also lighter in weight.

Whatever designs you choose, they must be durable and safe.

Don’t forget about comfort - the body should be comfortable during sleep or daytime rest.Remember that the base must be wide enough - at least 60 cm, otherwise the sleeper will not be able to turn around on the bed.

Today there are many varieties of this furniture. All of them find their place in the interior of the apartment.

Necessary materials

To make a frame model you will need the following:

• chipboard;
• Fiberboard;
• Wooden blocks;
• Plywood;
• Foam rubber;
• Self-tapping screws;
• Loops;
• PVA glue;
• Sandpaper;
• Upholstery fabric.

We will make a simple but convenient thing in everyday life that will be strong and reliable to withstand any unexpected guest.

In creating the design Others can also be used. For upholstery it is better to choose a special one textile , characterized by density and easy to clean.

For frameless furniture are used:

• Material for covers;
• Foam rubber;
• Strong threads.

For upholstery you will need high-quality foam rubber.

Required Tools

So that the intended subject furniture to do it correctly and firmly, you will need:

• Long ruler or tape measure;
• Simple pencil;
• Staples and construction stapler;
• Scissors;
• Hacksaw;
• Screwdriver;
• Sewing machine (for making a frameless chair).

Tools for work.

If in design decor is provided (for example, in the form of appliqués), then a stencil cut from a thick file folder will be useful.

Manufacturing process: step-by-step instructions

Before starting work, it is imperative to complete a drawing of the product, where the exact dimensions will be indicated and parts of the model will be drawn in detail.

Product drawing.

For the manufacture of folding chair frame type you will need plenty of space. Choose a spacious room.

First we make the body:

Then we start creating the folding part. Make 2 frames from beams the width and length of the seat. Attach sheets of plywood to them.

Connect the frames using long loops.

To ensure that the chair reclines evenly, use a metal transformation mechanism - attach steel contours with through hinges to the sides.

The main thing is how to make a chair bed yourself, so that the parts folded together form a beautiful and even square.

This cute chair bed that we made with our own hands can be painted, varnished, or upholstered with foam rubber and stylish, beautiful fabric.

The next step will be plating:

1. Glue pieces of foam rubber cut to size, 2-3 cm high, to the top of the frame.
2. Place the fabric evenly and use a stapler to attach it to the beams at the bottom.
3. The sides can also be upholstered using a thin layer of foam rubber.

For folding design you will need legs.

They are made in the middle and front part of the frame, level with the bottom point of the bottom or slightly higher. For armrests, use stripped sandpaper wide bars.

The seat easily unfolds without clinging to the sides, and just as quickly turns into a chair.

The frameless model is much easier to manufacture. It requires foam rubber, which can be used in 2-3 layers, and thick fabric like a “raincoat” (or less slippery). The cut material is sewn on several sides. the remaining opening is intended to be placed inside the foam.

In order to prepare the chair-bed for sleeping, you should unfasten the straps, then pull the top pillow towards you.

Equip the unsewn section with a zipper. For more practical use Using a frameless sample, make an outer cover.

Since it does not have a rigid base, the backrest should be placed against the wall

Decorating a chair-bed

In order to give finished product stylish and original look, use your imagination.

The design of the created item can be improved through the use of interesting prints and appliqués.

Tapestries look good from the fabrics used for decoration. If you want to make the upholstery softer to the touch, choosewith a pile like artificial velvet.

This material is also more durable and durable.

It is better to sew appliqués before the upholstery process. To keep them neat, prepare stencils and scraps in advance different color, matched to or contrasting with the main range.

For a frame-type folding chair, the front legs, which are not retractable in all models, can be made carved or metal.

To prevent the surface from collecting dust and rubbing, use a cape or sew a special cover. Carpeting of the appropriate size will also work, and artificial fur– this will make sitting in the chair more comfortable and cozy. Another option is to sew replaceable covers from lightweight fabric.

This will make caring for the upholstery easier.

The chair is good place both for work and for leisure. Before you make a chair with your own hands, you need to familiarize yourself with its models, since there are a large number of. For some models of armchairs, willow or rattan is needed, since, being presented in other materials, they lose their charm. This piece of furniture can also be made of metal - forged rocking chairs look like jewelry in the interior.

DIY chair - wooden chair

Solid wood furniture is a symbol of solidity and reliability, even if it is lattice models. Making a chair from timber does not take much time, and it can serve for many years without needing restoration. To make it you will need:

• medium thickness timber;
• plywood;
• wood glue;
• primer;
• stain;
• furniture dowel;
• self-tapping screws;
• sandpaper 3 types;
• Bulgarian;
• screwdriver;
• hand drill;
• plane;
• clamps;
• sponge or foam rubber;
• brushes;
• pencil or marker;
• square;
• dye.

Tools for making a chair.

Beam thickness of great importance does not have it, but when purchasing you need to pay attention to a single section, which simplifies the work and shows the quality of the workpiece.

Ideally, all workpieces should be of the same thickness and with good linearity.

If one of the parts is twisted, this will greatly affect the integrity of the product; it may warp or crack during operation.

How to make a chair - the manufacturing process

The timber is sawn into the required number of cross bars and supporting additional seat cross bars. Availability allows you to work well and quickly circular saw. The edges of the resulting bars are marked and drilled at the same distance through holes. The distance from these future fastenings to the edge of the block must be at least 25 mm, otherwise a chair made with your own hands will not be strong enough. It will help to maintain exactly all the parameters for many holes drill stand, where you can set parameters such as the perpendicularity of the holes, their sizes and distances.

Before making a chair, one more safety concern is required - to treat the ends and surface of the slats to prevent the appearance of splinters during operation.

In this case, all existing ribs are rounded using a grinder or plane. When the longitudinal slats are ready, the remains of the timber are divided into squares using a circular saw, which will be used to separate the slats from each other in the structure.

Assembly diagram garden chair.

Holes are also drilled in them, coinciding with those already existing on the finished bars; they need to be sanded and the ribs smoothed. Each master will determine the number of long bars and squares for himself, based on the size of the chair and the thickness of the bar.

Dowel fastenings are inserted into the holes, a few drops of glue are added, after which each block on both sides is connected to a pair of cubes. The workpieces are aligned along the edges by attaching a lath, then left to dry, tightened with clamps. After drying, the wood is treated with stain. You can thread a rope through the holes on the parts and hang the painted parts to dry. Varnishing occurs in the same way.

To make a chair with your own hands, the back and seat for the chair are cut out of plywood. They are screwed together using a pair of screws on the right and left. Dowels can add additional strength if you drill holes for them and glue them first before use. All parts are painted in desired color and after drying they are varnished. All that remains is to complete the final assembly of the body using bushings and screw the seat. This unusual shape a bright and catchy chair complements the interior well.

DIY easy garden chair

Not everyone likes plastic chairs, which are now widely used to decorate recreation areas in the country house or garden. Light garden chairs made of wood look more appropriate on the site, and their production does not take much time. Before making a chair, you need to take into account that its design should be light and comfortable; it is best to prefer a folding chair. This will allow you to quickly move the furniture under the roof in case of rain, because even well-treated wood should not be exposed to moisture.

Connection diagram for chair legs.

The wood to make a chair must be chosen from hardwoods such as beech, walnut or oak. Pine, cedar, larch or aspen are also less susceptible to rotting, but pine is not resistant to mechanical stress and large dents remain on the surface. The boards should be well dried or dried under a canopy before starting work. The following materials and tools will be needed:

• Circular Saw;
• milling cutter;
• hacksaw;
• plane;
• screwdriver;
• drill;
• clamps;
• sander;
• roulette;
• square;
• pencil;
• sandpaper;
• screws or self-tapping screws;
• wood glue;
• drying oil or furniture varnish;
• stain.

Preparation and assembly of parts

A garden chair will require two back and two front legs, with the back legs being longer. You need to cut out 2 supports for the armrests, a backrest and a jumper. For the rear pair of legs, armrests, backrest and seat, boards selected in color and texture are glued together until the desired width is obtained. To properly glue the wood, grooves for dowels are selected at the ends. Paired parts can be cut simultaneously by holding two boards together with clamps.

Drawing of a rocking chair.

The parts are then adjusted to size using a router or plane. When cutting out the back, the glue seam, if present, should be placed in the middle of the part. The upper edge is rounded, and after that you can begin assembling the garden chair, adjusting other elements as needed.

The rear legs are attached to the back with screws and reinforced with glue. To prevent the workpieces from cracking during assembly, holes for fastenings can be drilled in advance. The strength of the assembled seat will depend on the correct placement of the boards on it. They should lie in the direction from one leg to the other. The front legs are also screwed onto screws or self-tapping screws, reinforced with glue.

The reliability and stability of the chair is given by the leg - a jumper located between the front legs. They attach it in the same way as everything else, using glue and screws. Then the armrests and the support for them running behind the back of the chair are attached.

The heads of all screws used for fastening should be sunk flush with the surface, and then closed with special plugs. The wood of the finished chair is impregnated with hot drying oil or stain, dried, and varnished in several layers. You can opt for a special furniture varnish, but the most durable coating is found in parquet or yacht varieties.

Design for rocking chair

This chair can be used both in the garden and at home. By expanding the seat, it is possible to make not a chair, but a whole bench that can accommodate several people. For production you will need:

Chair seat assembly diagram.

• electric jigsaw;
• sander;
• wood drills of different diameters;
• screwdriver;
• square;
• roulette;
• pencil;
• plywood;
• self-tapping screws;
• confirmations;
• slats.

If the rocking chair is made by hand from start to finish, it is better to use high-quality materials so as not to spoil the work.

Making a rocking chair

The sides of the chair with a rounded bottom are cut out according to the developed pattern first. They must be completely identical, and there should be no protruding corners on their lower part. Then the timber for the seat and back is cut, the quantity and length of which must be calculated separately for each model. The surface of each block is sanded and polished, and the corners are smoothed. If you plan to use the chair outdoors, the ends of the boards need to be given Special attention. They are varnished at least 3 times, since it is there that the wood is especially loose and needs protection from atmospheric influences. To protect street and garden furniture from destruction, the ends are impregnated with hot drying oil several times, and the fibers are flattened with a hammer.

The sidewalls are pulled together to the required size using several drawbars, drilling through the sidewalls. Then holes are drilled at the ends for fastening the bars. The bars themselves are also drilled in advance to avoid cracks during operation. It is more convenient to fasten the bars not between the sidewalls, but on top, slightly going beyond the contour. This rocking chair has more space and looks neater. Each screw should then be coated with an antiseptic and a plug placed on top. After this it is done finishing products with waterproof types of varnish, with each layer drying for at least 12 hours. Place at least 3 layers, coat with a thick layer, trying not to leave gaps. Only after this can the rocking chair be considered ready.

In this article we will consider the topic of manufacturing classic furniture Almost all apartments and houses - a chair with your own hands. This solid wood chair with armrests will not be bulky and best use such products are tableware. Following these instructions, you can make it at home.

The production of the chair will take place in several stages. All of them will be presented below and you can easily make it in a few evenings if you have the tools and materials, because all the schemes will be presented below. There will be no ready-made drawings in this article, since everything is done from improvised means: from boards, plywood bars, which are available.

Frame

Let's call this stage the chair frame.

Of course, almost the entire skeleton will be covered with foam rubber and fabric. Only part of the legs will remain visible.

The back legs are the most important parts of a wooden chair because you need to make them at some angle.

Without thinking for a long time, to make the back part of the chair structure, we took an ordinary dining chair that was available, although it did not have a seat. But he was well suited for the role of template. You can take some old grandma's chair.

Markings were made on a 50x150 board.

Be sure to mark the level of the seat of the chair, make it the same as for the chair. In this case it was approximately 410 mm from the floor.

For sawing out homemade legs fireplace chair use a jigsaw.

Then we used the finished part as a template to make three more legs, because we are making two chairs at once with our own hands from scrap materials.

The front legs will be straight and square section- 55x55 mm. To obtain such a cross-section, you can glue the boards together, and then saw them down to required size. We glued 2 pairs of 2 boards, 120 mm wide and 30 mm thick.

There is no glue between boards 2 and 3

Note. A chair with a solid structure is called a frame chair.

While the front legs were drying, we finished assembling the back frame - we made the upper part, the upper part of which has a slight rounding. Then we made the rear seat support bar.

Every person wants to make the environment of their home or apartment as cozy and comfortable as possible, but at the same time unlike any others.

You can achieve a unique interior with the help of hanging chairs. They can be purchased at furniture stores or made yourself.

Today on the Internet and in specialized magazines you can find drawings of the chairs of the different designs and shapes.

In our article we will look at how to make such a chair with your own hands.

Types of hanging chairs

Today, manufacturers offer a huge range of hanging chairs, including those that you can make yourself.

Such furnishings can become an unusual accent in the design of a room. Below we will look at several options for chairs that you can create yourself.

Chair in the form of a swing

In the manufacture of original hanging swing chairs, the most different materials. Such models are characterized by elegant appearance, fairly simple design, hard or soft frame. They will perfectly decorate the cottage.

They can also be used as an original piece of furniture for a bedroom or children's room, or terrace.

Chair in the shape of a cocoon

This is one of the most common models of hanging chairs. The difference between such a chair is the presence of hiding inner part wall chairs.

This product was created to enjoy solitude; children also really like it, as it looks like a hanging house. To make a cocoon, only natural materials are used.

Chair in the form of a nest with a frame made of hoop

These chairs are the most popular. They can be equipped with a large amount of decor and perfectly complement modern interiors. For such models, a variety of weaving techniques are used.

What are the chairs made of?

When choosing materials for a chair, it is necessary to take into account its specifics.

If you decide on the swing chair option, then you will need thick fabric, different types artificial ropes and blocks of wood.

To make a chair in the shape of a cocoon you will need rattan, willow twigs, bast, bird cherry or willow branches.

For a chair in the form of a nest, a hoop made of plastic or steel, durable fabric resistant to wear, synthetic filling, special cords for weaving, and various pieces of wood are suitable.

For the seat itself, the following techniques are used:

• Macrame;
• Patchwork technique;
• Knitting;
• Tatting.

Do not forget about the compliance of the selected materials and fasteners with the planned load.

Note!

Master class on creating a chair

This is the simplest type hanging chair of all the things you can do yourself. To make it you will need:

• dense material – 2 m;
• wooden beam - length 1 m, radius 3 cm;
• several carbines (0.11 m), designed for a weight of up to 0.16 tons;
• cable with a diameter of 1-1.15 cm with a tensile load of up to 3200 kgf;
• paints, brushes, nylon threads.

The tools you will need are a drill, sewing machine, iron, scissors, ruler.

Step by step we create miracles

Step 1. Fold the material in half, measure 0.18 m from the top and cut off the resulting triangle.

Step 2. Fold the edges of the fabric by approximately 1 - 1.5 cm and carefully hem them.

Step 3. Make pockets for the cable. To do this, you need to bend the edges on the long part by 4 cm and stitch them on a typewriter.

Note!

Step 4. On each side wooden beam make 2 holes. There should be a gap of 5 cm between two adjacent holes, and approximately 0.8 m between pairs of holes.

Step 5. We insert the rope into the central holes and secure it with knots. First, we make a knot for the carabiner in the middle of the rope.

Step 6. Pass the ends of the cable through the prepared fabric, insert them into the free holes and secure with knots.

Step 7. We attach a pair of carabiners, which are connected to each other, to the hook previously attached to the ceiling. This will add reliability to the design. We insert the rope into the last carabiner.

You can decorate the swing chair with bright pillows.

Note!

Hanging chairs are a fairly popular piece of furniture. They can easily become the highlight of your interior.

We hope that this article has convinced you that sewing a stylish bean bag chair or a fashionable hammock chair with your own hands is not at all difficult.

Such self-made products have a unique charm. They will definitely amaze your guests with their uniqueness.

DIY chair photo

Much has been written about the beneficial effects of relaxing in a rocking chair. It also helps to concentrate during intellectual work. Finally, it’s just convenient, after pumping, to take books from the rack behind your back or a cup of coffee from coffee table. The prices of ready-made rocking chairs, as it should be in a consumer society, react to such advantages in their own adequate way: a rocking chair for 5,000 rubles. it's still cheap. And people are artisans and also respond adequately in their own way: there are more and more people wanting to make a rocking chair with their own hands. However, the rocking chair differs from other pieces of furniture, firstly, in that the whole thing moves and swings. Secondly, so that it does not turn from a rocking chair into a kicker or tipper, the entire product with the person sitting in it must have an accurate balance, which must be maintained within acceptable limits for riders different weights and complexion. This publication is devoted to consideration of issues of how to achieve the required qualities of a rocking chair.

Types of rocking chairs

You need to comply with your own needs already at the stage of choosing a prototype. There are several types of rocking chairs, aimed at users with different habits and needs. The main types of rocking chairs are shown in the photo. Rocking chairs on simple radius runners (arches, rocker arms, skis) were the first to appear in everyday use. They are in use to this day, both in modern and classic appearance, pos. 1 and 2. Their main advantage is constructive and technological simplicity.

Radius runners provide smoothness and softness of rocking only with relatively small swings, and with strong swings they do not guarantee against tipping over. Therefore, rockers “on radii” are made with a low landing, ensuring a large excess of the center of the generating circle (CO) over the general center of gravity (CG); For more details on the kinematics of rocking chairs, see below. If a seat of normal height is required, then the runners are equipped with bumpers, pos. 3. The shocks of the bump stops on the floor are noticeably felt at the “fifth point”, and in any case, you have to get out of the rocking chair on the radius runners, straining somewhat.

Note: Stability when swinging with a slightly larger amplitude at a normal landing height is provided by rockers on radius runners with a closing horizontal arc, see fig. on right. But, suddenly the limit is reached, the supporting surface instantly reduces to a point and a sharp push follows in the back.

Tipping is excluded in rocking chairs on runners of variable curvature, pos. 4. All of them are comfortable enough for riders of different body types. They themselves gently unseat the rider of a rocking chair of the Nirvana type who has stood up and leaned forward on runners of variable curvature, pos. 5 and 6. It is also possible, by changing the progression indicator in the law of change of the generating radius (also see about kinematics), to design them for any landing height, within acceptable limits.

Note: mother and baby give good rest with complete unity of souls of the rocking cradle. Reliable rockers with a cradle are made only on runners of variable curvature, see fig. on right. Otherwise, suddenly the little one will get worried and the mother will perk up, and we can tumble together. Which is simply dangerous for a baby.

Nirvana rocking chairs on elliptical runners, pos. 7, provide a gentle, truly blissful rocking, but do not prevent tipping over during strong swings, so they are equipped with bump stops; the front one is often combined with a footrest. Garden rocking chairs with ellipse awnings never tip over, pos. 8.

Nirvana rockers on springs, see fig. on the left, they swing as softly as on ellipses, because mechanical characteristics Progressive springs. But making a spring chair with your own hands is difficult: you need either high-quality boards of special types of wood (teak, boxwood, dogwood) or a rubberized strip of spring steel so that it does not scratch the floor. In addition, dirt gets packed into the gap between the spring and the runner and it can be very painful to pinch your finger. For the latter reasons, spring chairs are now very rare on sale.

Rocking chair 3 in 1

Finally, there are also multifunctional “3 in 1” rockers on runners with smooth bends, see fig. on right. When seated upright, this is a regular chair; by leaning back, it can be switched to rocking mode on radii, and by leaning back even more, it can be turned into a sun lounger. But the dimensions of the 3 in 1 rocking chair are too large for apartments below business class, and transitions from mode to mode are accompanied by rather sensitive shocks. In unsuccessful models, you either have to stand up or twitch, squirm and fidget like a puppet on strings. Therefore, 3 in 1 rocking chairs are a piece of furniture for everyone.

To start

Without any special pretensions, just to relax after work, a rocking chair on radius runners will help. Drawings of a simple sample, made, with the exception of the runners, only from straight parts, are given in Fig. For a dacha, veranda or garden, this chair can be made in half a day, using only a jigsaw, a drill and a couple wrenches(assembly - bolted). And having swayed to your heart's content, you might already think about home rocking chair for the more experienced; then you will need a more thorough tool and knowledge.

How does it swing?

Most home craftsmen make rocking chairs according to ready-made drawings, but prototypes often turn out to be developed and tailored to a specific person, and an exact replica is not so convenient. Therefore, before making a rocking chair, it is necessary to obtain at least initial information about its kinematics.

The CG of an upright person of normal build is located on the border of the lumbar and sacrum with inside spinal column. In a sitting individual, it will blend somewhat forward and even less downward. In the chair-seat system, the overall CG shifts back almost to its original position and a little further down. The downward shift of the general CG for the design of a rocking chair is not particularly significant and we can assume that the projection of the general CG onto the supporting surface (floor) is approximately the same as that of a standing person. In the future, the resulting error can be easily compensated by final balancing of the chair, see below.

The vertical location of the central center relative to the central center has a much stronger effect on the stability and comfort of the rocking chair; the latter is also a determining factor when designing rocking chairs on runners with variable curvature. If the CG and CO coincide, this is an indifferent equilibrium: for any physically possible tilt of the chair, the projection of the CG on the floor falls on the point of contact of the runners O, pos. 1 and 1a in Fig. The chair does not rock, and if you lean back too much, you will instantly somersault with the risk of breaking your neck. Fortunately, an exact match between the CG and the CO is only theoretically possible.

If the CG is higher than the CO, then its projection, at any inclination, “runs” outward, backward or forward, from the point of contact. At the slightest tilt, a tilting moment Mo occurs (positions 2 and 2a), and the rocking chair turns out to be unstable. To avoid such a situation for a family rocking chair, it is designed and balanced for the tallest, heaviest and pot-bellied rider possible so that its CO is 450 mm or more higher than the CO. Then, when the chair is tilted, the point O will “run away” from the CG projection, the restoring moment Mv will constantly act (positions 3 and 3a) and the chair will not tip over when rocking within acceptable limits. For those who are smaller, the excess of the CO over the CG will be too large, and the swaying will be harsh, but this can be easily compensated for by pillows under the back and seat. In general, the lower the elevation of the CO above the CG, the softer and smoother the swaying, but the likelihood of capsizing, suddenly straightening up and standing up in a chair, is higher. Therefore, it is better for novice carpenters to set the CO exceeding within 600-700 mm.

Note: if it is impossible to determine the position of the CG of the largest of the riders (say, in his absence), the radius of the generating circle R is taken equal to the average height of the users minus 5 cm. Suddenly the rocking turns out to be harsh, this can be corrected by placing a permanent pillow on the seat.

There is no need to drag your own pillows with you into a chair on runners of variable curvature: it will itself rise to the position of greatest comfort. At the same time, the big guy will lean back more, and the slender one will sit straighter. When swinging backwards, the point O will run away from the CG projection the further, the greater the angle of inclination, and it will simply not be possible to swing until it capsizes. And if you “pump” forward, which is actually difficult, the chair will smoothly drop the hyperactive person onto the floor: where should you rest? Go do something.

To construct a profile of runners of variable curvature, the radius of the generatrix of the circle (it is determined as in the previous case) will have to, firstly, be rotated several times by a fixed angle α; usually take α = 10 degrees. Secondly, to build the rear branch of the runner, R is increased at each turn according to the law of geometric progression with the index k = 1.02-1.03. That is, it will be (see position 4 in Fig.) R1 = kR; R2 = kR1; R3 = kR2; R4 = kR3, etc., if required. Actually, R changes according to some trigonometric function, but for furniture accuracy and the size of the rocking chair, it is more convenient to replace it with a progression, so it’s easier to count.

The construction of the anterior branch is carried out at a constant R, but with each rotation of the generatrix of the circle, the CO is raised vertically (ibid., in position 4 of the figure). The initial elevation Δh1 is taken equal to 2-3% R, i.e. (0.02-0.03)R, and the subsequent ones also follow a geometric progression with the same indicator as for the posterior branch. Δh1 in this case is a fairly critical value; its smaller value should be taken for thin people, and its larger value for fat ones.

Finally, the resulting points are connected using a pattern with a smooth curve. Do not be embarrassed if the tangents to it turn out to be not perpendicular to the radii: in order for the chair to be stable, at each moment of rocking it should be on the opposite slope. When constructing, it is advisable to take the scale no smaller than 1:5.

Note: if a nirvana chair is designed, but the front ascending branch of its runners will be an elliptical arc (green dotted line in position 4), tangent to the constructed profile of the runner in volume I there.

Final balancing

It is unlikely that a novice craftsman will immediately find a rocking chair comfortable enough. Most likely, the product will need to be balanced. If the chair doesn't rock well, and when you get out of it it pushes, you need to make the rear overhang heavier. The easiest way to do this is to connect the ends of the rear branches of the runners with a low U-shaped beam of boards, with the notch facing down. Weights are placed in the recess. The lever arm in this case is long, so there is no need to hang weights. Another option, depending on the design, is a transverse pipe beam with a weight inside. But during the balancing process it will have to be removed and put back several times. If the rocker tends to fall back, you need to make the front overhang heavier. The easiest way to do this is by placing a step and attaching weights to its underside.

About materials

Rocking chairs are made primarily of wood. Metal, for all its manufacturability, low waste and greater resistance to outdoors, too heavy. The influence of the chair on the overall CG turns out to be significant, the moment of inertia of the system is large and, as a result, the rocking is too sharp. Or you have to set an extremely small initial elevation of the CO above the CO, risking that the rocking chair will tip over under someone. However, we will return to metal rockers when we consider individual samples.

Plywood is a completely different matter, especially for novice woodworkers. Firstly, making the parts of the rocking chair with 3-layer glued ones, you can only make accurate and strong connections tongue and groove, on the left in the figure, if you follow the following. rules:

• Plywood for the middle layer is taken twice as thick as for the outer layers. For example, if you need a total thickness of 20 mm, then glue 5-10-5 mm.
• The parts are assembled from blanks using 2-component waterproof glue. If it is on PVA, be sure to reinforce it with small nails.
• The connections are assembled with gluing (wedging in this case is unacceptable) and reinforced with diagonal pairs of self-tapping screws on both sides.
• The supporting surfaces are protected with linings made of thin (6-10 mm) strips of hard durable wood or dense sheet rubber 4-5 mm thick. Plywood under a concentrated load cracks very well at the end.

Secondly, plywood makes it possible to use non-standard technical solutions, eg. as on the right in Fig. Such a rocking bowl can be made from plywood, again using only a jigsaw. Convenience is high, stability is absolute, and can serve hanging hammock chair or a swing chair. The thickness of the lamella boards is from 12 mm; connecting half-washers on poles – from 24 mm.

Note: in any case, the finished plywood rocking chair must be soaked twice with a water-polymer emulsion or liquid acrylic varnish on water based. This will not only increase the strength of the product and its resistance to external influences, but will also relieve excess residual stresses in joints and bent parts.

How to install overlays

Wear-resistant wooden pads are installed on the rocking chair runners. way:

1. Turn the chair over with the runners up;
2. We warm the blank plank thoroughly with a construction hairdryer;
3. We place the workpiece on the runner and wrap it tightly along the entire length with cotton braid. Don't get burned, the wood is very hot!
4. We also grab the second workpiece onto another runner;
5. Once the strips have completely cooled, remove the braid bands and glue the pads with PVA on wood or with 2-component glue;
6. We attach the ends of the planks with small nails until the overlays fit snugly along the entire length. Place washers or pieces of plywood under the nail heads;
7. Once the glue has completely dried (2-3 days), remove the temporary fasteners. We drill blind holes for screws and secure the ends completely;
8. We fill the holes with the fastener heads with putty made from sawdust of the same tree, thickly mixed with PVA.

Note: The linings need to be secured with metal hardware only at the ends. Otherwise, when the lining wears out during use, the fastener heads will stick out and begin to scratch the floor.

Examples of rocking chairs

Metal

Let's start our review of rocking chairs with metal ones, because... making rocking chairs out of it is justified in few cases. Forged rockers, imitating classic wicker ones from wicker or rattan, as requiring special equipment, a forge, etc. We don’t touch qualifications. But a metal rocker “like a braid” can be made by welding from profile pipe; preferably elliptical section. In this case, you need to choose the kinematic diagram of the nirvana rocking chair as the least sensitive to the excessive elevation of the CO above the CO; it also corresponds well in design to wicker rocking chairs, see Fig. In order not to increase the moment of inertia, the seat is made of braided cables, belts, etc.

It also makes sense to make garden tumbler rockers from metal, see below, due to its strength and resistance to wear. But a welded frame like the one in pos. 1 pic. on the right - the solution is not optimal, it is too complex, labor- and material-intensive. Much easier to do steel frame garden rocking chair, Concept type, pos. 2. Pipe – round from 40x2. The bed itself can be sewn like a hammock; balancing - by changing its tension and, accordingly, sagging. As a result, the work and costs are much less than repeating the established forms of rocking chairs that come “from the tree,” and the comfort is no worse.

Here we can see another interesting option: the frame of a rocking chair Concept made from... gymnastic hoops. Just not aluminum or propylene, but carbon fiber (carbon). Strength is monstrous, durability is absolute, weight is negligible. The same cannot be said about the cost, however.

Vanka-Vstanka

IN Lately Garden rocking chairs - tumblers - have gained popularity. If you lean back completely in this one and tuck your legs, it falls back almost 90 degrees without losing stability; the rider will find himself lying on his back with his knees at the zenith. And if you stretch your legs forward, the rocking chair - the vanka-stand-up chair becomes its normal position and then you can rock as always.

The Vanka-Vstanka toy with a spherical bottom sways quite sharply. Comfortable rocking of the tumbler rocker is achieved by profiling its runners according to a complex law. It will not be possible to build their sidewalls “school style”, as described above. You need to be guided by proven samples and draw markings on the grid, see fig. The inset version, with cladding made of planks 30-40 mm thick, is more expensive, but less labor-intensive. It also allows you to increase the length of the rocking chair by installing intermediate supports-runners.

Note: wooden balls are placed on the protruding ends of longer rods (1050 mm) and form handles for rocking and carrying.

Rocking bench

Rolling your heels into the sky, throwing your hands behind your head and admiring the clouds floating in the blue heights through the fluttering foliage is a heavenly pleasure, but it doesn’t suit everyone. Some people want to look more impressive while relaxing. This is more suitable garden bench– rocking chair, see fig. It is a little difficult to swing on it, its own moment of inertia is large, but it also swings for a long time. The maximum span between supports with runners is 750 mm with cladding made of 40 mm thick slats. The back covering is decorative.

Sun lounger with awning

Both those and other requests will be satisfied by a garden rocking chair on elliptical runners and with an awning. The dimensions of its sidewalls are given in Fig. their material is 24 mm plywood. The width of the bed is up to 900 mm, its covering is made of 50x50 slats. The places of the sidewalls, indicated by gray circles, are connected by round ones wooden crossbars with a diameter of 60 mm.

Rocking chair

We are not talking about rocking horses here; they are toys, not furniture. But it’s also not harmful for children to rest while rocking, so it makes sense to give your child a rocking chair. Its proportions will be slightly different than for adults, due to the influence of the square-cube law.

The structure of a children's rocking chair, its assembly diagram and specification of parts are shown in Fig. material – wood. More or less experienced home handyman building a rocking chair for a child, guided by these data, will not be difficult, and beginners can first watch a master class on making an almost identical children's rocking chair.
