Any nursery requires a fairly large amount of furniture, each piece of which should go well with the rest of the interior. Collecting a complete picture from individual details can be difficult, especially if the space is significantly limited, and there is not too much money. If you need to solve all these problems at once, you should pay attention to children's walls with a bed.

Features, pros and cons

A children's wall with a bed is a fairly wide set of furniture, the main and indispensable element of which, as the name implies, is a children's bed. In addition, the creators add something else that a child may need, for example, a wardrobe or just shelves, a desk or a computer desk with drawers.

The specific configuration depends only on the chosen model and the imagination of the designer who created it, so some of the described may not be, but it is possible that there will be something else and no less useful.

Naturally, such a solution has a number of advantages:

• Don't have enough artistic taste to elegantly furnish a nursery? Buy a wall with a bed - there will be everything you need, designed in the same style.
• Little space? This is not a problem if you prefer the wall, because it is compact enough to fit in any room, and in terms of functionality it can replace several separate pieces of furniture at once. Moreover, if the dwelling is so small that there is no way to allocate for a nursery private room, and the child has to live in the same room with the elders, this is the perfect solution to zone the space.
• Do not have sufficient financial resources to immediately purchase everything you need? It doesn’t matter, because wholesale is cheaper: a wall consisting of a bed, a wardrobe and a table will cost much less than all these items separately.

The only possible negative that can be attributed to a children's wall with a bed is related to the possibility of expanding as the child grows. If by the bed child size, then the small owner will sooner or later outgrow it, and at that moment, instead of replacing one bed You will have to change all the furniture in the room.

True, usually the walls are produced in a modular version, that is, they can be disassembled, and then the table and cabinet can be left, but the question remains whether they will now be normally combined with the rest of the situation.

Kinds

There is no clear classification of children's walls, despite the rather significant variety of models. To simplify the search for what you need, let's try to delve into the specifics of the varieties of such furniture in more detail.

It’s worth starting with the fact that a bedroom set with a wardrobe is not necessarily equipped with a bed - a sofa can quite successfully perform its functions, especially since such a solution looks somewhat more presentable. Particularly functional walls are equipped with both a bed and a sofa at the same time - the retractable last element is hidden inside the first.

However, most models are still equipped with a crib, although there are options here - some walls are created for boys, others for girls, plus gradation by age - for preschoolers, schoolchildren and teenagers.

Designers did not miss the moment that there can be more than one child in a family, and in this situation, saving space and money is even more relevant. For such cases, modular walls with two beds have been created, and if the area is critically small, the design can be equipped with a built-in folding bed- in this case, the front wall lowering mechanism is controlled by a button. There is also an alternative for small areas- bunk bed.

By the way, bunk beds give additional features to equip the wall with various additional bonuses, in particular, one of the children will still have to regularly climb up the ladder, and after all, it can be successfully replaced by a Swedish wall for both children. The imagination of the designer can give the second tier appearance, like a village house or in any other way add a little mystery to it. In some cases, a slide is also adapted for the descent from the second tier, but this decision is relevant only if the children are still small, and the choice in favor of the wall is not made because of the limited size of the nursery.

Finally, there is also a division in form. In addition to the straight, classic wall, there is also an angular variety, and even a U-shaped one that overlaps two adjacent corners of the room at once.

Styles

The style of children's walls very much depends on who it is purchased for. this furniture. Usually there are headsets for boys and girls.

Headsets for young ladies are usually distinguished by gentle, typically feminine colors, as well as especially soft lines and elusive charm. Hand-painted models are highly valued. Plots, again, purely girlish - fairy-tale heroes for the little ones, flowers and butterflies for those who are a little older. Since girls always have a lot of different cute knickknacks, they will appreciate the presence of a large number of lockers, and open shelves will allow them to put their favorite exhibits on public display. And, of course, what girl doesn't appreciate a built-in mirror?

Headsets for boys look somewhat stricter, even if they are created specifically for kids - this is usually expressed in a form that looks more rigid. The design often corresponds to the hobbies of the child: from marine style for little pirates and explorers to racing cars and the number one sport, football. Sports equipment, such as Swedish walls, rings or bars, will also cause much more delight among boys.

Material and color

Solid wood of durable species has been the optimal solution in terms of durability for many centuries - especially since this material is of natural origin and is absolutely safe for children. The second place is held by a material invented relatively recently - MDF boards, which are produced from wood pressed under high pressure. This solution is somewhat inferior in strength to the classic tree, but it costs much less. Regardless of the choice of base material, it is important that it is adequately reinsured. metal fasteners and amplifications.

As for other materials, they are much less common. The metal would have held the expected load just fine, but it's too cold to fit. Plastic is acceptable only in the form decorative material, and even then - only on condition that there are all certificates of its safety. But chipboard has recently been subjected to merciless criticism for its rather high toxicity.

If we talk about colors, then the main requirement here is the correct compatibility of the color of the headset with wall decoration and textiles. The colors don't have to match, but the overall gamma should leave a good impression. For girls, pink, white, lilac and beige tones are recommended, although other colors are applicable for teenagers, for boys of any age everything is acceptable except pink and lilac.

How to choose a room?

The variety of models allows you to choose perfect option, but, on the other hand, can confuse the buyer. To make it easier for him to choose, here are some practical tips:

• When choosing a color, be guided by the age of the child. Toddlers love bright colors and beautiful pictures, but for a teenager this is no longer interesting, a monophonic option would be better for him. For a student, buy what he is closer to from the named, taking into account the near future.
• One of the main advantages of the wall is its ergonomics, therefore, pay attention to how convenient shelves and cabinets are, do not be too lazy to check them before buying.
• Bad smell- an indicator of poor quality, and even toxic finishes, so you should not count on the fact that the stench will disappear.
• Do not buy furniture for a child solely on your own discretion.- ask his opinion about the model you like. Try to come to a common denominator, and if the points of view on a future purchase are radically opposite, do not press, but try to convince the baby with reason.
• If you are not ready to change furniture every few years, try to buy a universal wall suitable for all ages. For the same case, furniture of a new trend may come in handy - allowing repainting.

furniture requirements

For ease of use, the headset must meet some generally accepted requirements that you should pay attention to when buying. Here they are:

• Convenience and spaciousness. The walls are chosen precisely for these qualities, if the model does not match them, do not take it.
• Environmental friendliness of materials. Check the certificates - only in this way you will be sure of the durability of the furniture and its non-toxicity.
• Hardware reliability. It is this piece of furniture that fails most often - outwardly still nice closet have to be thrown away because of broken handles or loops that have nothing to replace. These elements must be of high strength materials.
• Design safety. sharp corners always present a certain danger, and in the case of children who love to indulge, even more so. Mirrors and glass are especially dangerous, so if they are, they should have a protective film on their surface.




Girls need twice as much stuff as boys, so roomy closets are a must. However, not all things need to be hidden, because photographs and soft toys you can decorate the room - for this you need open shelves.




For a boy, tenderness in design is unacceptable, because even the most Small child is the future man. A baby wall for a boy may look cute, but by no means sugary.

Young gentlemen usually have fewer things, so they are more likely to make room if circumstances so require. At the same time, you can make their common bedroom not look like a hostel, but a very cozy and stylish corner, where it is not a shame to bring guests.




For an overview of the children's wall with a bed, see the following video.

For a child in the first years of his life, the environment in which he sleeps is extremely important, because it is on his own bed that he spends most time. In addition, sleep products must also be comfortable for use by parents, and in this case, the most good decision there will be cots with a wall that can be removed or lowered. The bed with a falling wall makes it possible to combine the parent's bed with the baby's bed for the safest possible sleep. Also, lowering the front wall of the crib will allow the grown-up child to leave it at any convenient time during waking hours.

This is also very important because a baby who has reached a certain age tends to explore the world, as a result of which he learns to climb over obstacles, which means there is a chance of falling and getting injured. In this case, cribs of this type make the child's leisure time safer.

Cribs with a wall - types and benefits

A bed with a drop-down wall is very popular in the market, because such a product allows the baby to spend his time with maximum comfort and is very convenient for parents to use. Thanks to the mechanism, it is quite easy to put the baby on his bed and get him out of there. In this case, the side will not interfere with the mother or father, and after the child is laid down, there is always the opportunity to raise part of the structure or move the crib to the parent's bed to create a combined structure. As a result, the whole family will sleep together, which is pleasant for both the child and mom and dad.

The bed with the falling wall can be made in several types. In the first case, the mechanism can be built-in and in this case it is enough just to use it so that the side is removed under the bottom of the bed. In another case, the crib with a wall is solid and in order to remove part of the structure, it is necessary to unscrew the fasteners. Both options are quite convenient, but the first has more versatility. However, a drop-down bed is not for everyone, as the mechanism itself can emit a large number of noise, and low-quality products are unsafe for the child.

In any case, a sleeping place from a reliable manufacturer does not have such problems and is used long time without the slightest complaint. Thus, a comfortable children's bed of this type is a great option for parents and a child. A crib with a wall that can be removed can be equipped with an additional low side that does not cover one side of the bed to the full length. As a result, the baby will be safe during sleep hours, and during wakefulness, his movements will not be limited to anything. Such a device is conveniently installed and also comfortably removed, which makes it possible for both parents to mount it without the slightest problem.

Roll-down bed - comfort for children and parents

Lowering the front wall at the crib is a very convenient addition for both babies and their parents. The child in this case can very easily move around the room if the side is removed, and sleep safely when it is installed. At the same time, mom and dad easily manage to pick up the baby from his bed and put him back. After all, the mechanism for lowering the front wall at the crib allows you not to bend over the side and do everything you need with sufficient comfort. Thus, it is safe to say that such designs are the most acceptable and safe for everyone. It's confirmed in high demand on such products and their popularity among parents.

The technical solution relates to the production of children's furniture, or rather, cribs, and can be used in the manufacture of means for regulating and fixing the level of the back of a crib when caring for a child. The mechanism contains a bar, upper and lower stops, as well as a bracket installed in the back of the crib, consisting of a body, a button and a spring. The bracket is made with the possibility of moving along the rod and automatically fixing in at least one groove made on the rod. The bracket body is made in the form of a bushing with a through hole, and the button is made with an "8"-shaped through hole with the possibility of movement in the bracket body. The bar, stops, bracket, button can be made of metal, wood or polymer. The solution greatly simplifies the process of changing the position of the back of the crib, which ensures reliability and improves the functional and operational qualities of this type of children's furniture, and makes caring for the baby convenient and safe. 1 z.p. f-ly, 4 ill.

The technical solution relates to the production of children's furniture, or rather, cribs, and can be used in the manufacture of means for regulating and fixing the level of the back of a crib when caring for a child.

The prior art is well known means of a similar purpose.

A device for lowering a side guard US 5201085 is known, containing a two-part guide, a zigzag groove in the guide, a spring-loaded latch in the form of a bent rod, which is attached along the entire length of the bottom bar of the side guard. The disadvantage of this device is that all fastenings of the guides and the latch are visible, which violates the design of the bed. This device also does not adequately provide ease of use. In order for the mother to lower the fence, it is necessary to bend down to the lower bar of the side fence and press the latch or raise her leg to the latch.

Also known is a device for lowering a side railing US 6167580, containing a two-part guide, a zigzag groove in the guide, a latch that is attached to the end of the lower rail of the railing and has a complex molding shape. The C-shaped bracket, installed in the end of the upper bar of the side rail, performs the function of a roller. Both parts of the guides are installed in the selected grooves on the leg of the headboard. This device is taken as a prototype.

This device has the following disadvantages. The mechanism for lowering the side rail is also visible, as in the first version. The need to select two grooves strictly vertically for the installation of guides, which leads to an increase in manufacturing operations. The most basic disadvantage is that the movable guard is fixed by friction between the plastic spring and the part of the rail that secures the bed. During operation, wear of these parts occurs, and in the future it does not provide reliable fixation of the movable fence from accidental opening by a child.

Also known is a device for lowering a side rail RU 2242911, consisting of a guide placed in the groove of the back leg, which includes a zigzag groove, an arcuate leaf spring and an elastic shock absorber. Top part the guide is C-shaped. The spring-loaded latch and the T-roller are installed at the end of the movable side rail.

The closest is a device for lowering the side rails, containing the latch and stops. The fastening of the side railing in the upper position occurs due to an increase in the friction force between the clamping cams of the latch and uprights fence, which does not ensure the reliability of fixing the side fence. The level of location of the latch, which is attached to the base of the bed, does not correspond to the functional working area of ​​​​a person. Brackets having the length of the back do not allow to install a box on rails in the lower part of the bed between the backs - GB No. 2232195, cl. A 47 D 7/02, 1990.

The disadvantage of the above devices is the complexity of the operation of the beds, associated primarily with the problem of fixing at different levels of the back of the crib, which is so necessary when caring for a child.

The task to be solved by the claimed technical solution is to eliminate the above disadvantages, as well as to simplify the care of the child in the crib, as well as when he is placed in the crib and removed from it.

The technical result is the simplification of the operation of the mechanism for fastening the back of the baby cot, as well as increasing the reliability of fixing the back of the baby cot at the required level.

This problem is solved by the fact that the mechanism for lowering the crib, containing the bar, as well as the upper and lower stops, according to the claimed technical solution, contains a bracket installed in the back of the crib, consisting of a body, a button and a spring, made with the possibility of moving along the bar and automatically fixation in at least one groove made on the rod, wherein the bracket body is made in the form of a bushing with a through hole, and the button is made with an "8"-shaped through hole with the possibility of movement in the bracket body.

In addition, the bar, stops, bracket and button can be made of metal, wood or polymer.

The claimed technical solution is illustrated by drawings, which show only one example of the mechanism for lowering the baby cot.

7 - bracket button,

8 - spring.

The following is one example and is not intended to be limiting in any way. possible options implementation of the claimed technical solution.

The bar (1) with the upper and lower stops (2 1) and (2 2) placed on it, is attached to the side post of the back of the baby cot (14) by means of fixing holes (5), for example, threaded ones, with fasteners (for example, screws) (not shown).

When the bracket (3) moves along the rod (1), its button (7) is pressed in under the force of the spring (8). At this moment, the through hole (9) of the body (6) of the bracket (3) and the hole with the largest diameter from the “8”-shaped through hole (10) are on the same axis, thereby ensuring free, unhindered movement of the bracket (3) along the rod (one).

At the moment the bracket (3) hits the groove (4), under the force of the spring (8) the button (7) automatically rises (snaps) and the bracket (3) is pressed against the rod (1), since the rod (1) falls into a hole formed by the edges of the through hole (9) of the body (6) of the bracket (3) and the edge of the button (7) formed by the hole of the smallest diameter of the "8"-shaped hole of the bracket button.

Under the action of the spring (8), the button (7) is still in a state that ensures that the bracket (3) is pressed against the rod (1), that is, the bracket (3) is fixed on the rod (1).

The groove (4), according to this solution, is made cylindrical, since with such an implementation, the formed shelves are perpendicular (that is, at an angle of 90 °) with respect to the axis of the rod (1), which ensures maximum security holding the backrest of the baby cot on the bar (1).

In conventional grooves, the shelves are flat, which, during prolonged use of the crib, leads to their “grinding”, which, in turn, is not safe for the child, since the backrest can either arbitrarily or under a slight load fall down.

If it becomes necessary to lower the back of the baby crib down, it is enough to press the button (7), after which the through hole (9) of the body (6) of the bracket (3) will be on the same axis with the hole of the largest diameter from the “8”-shaped through hole ( 10), thereby releasing the rod (1) from the previously formed engagement.

After that, the back of the crib can be lowered.

Thus, the claimed technical solution greatly simplifies the process of changing the position of the back of the cot, which ensures reliability and improvement of the functional and operational qualities of this type of children's furniture, and care for the baby becomes convenient and safe.
