Description

The utility model relates to mattresses for placing a user on them to relieve tension from human muscles, and more specifically to orthopedic mattresses for the prevention and treatment of various diseases and the creation of comfortable conditions for sleep and rest.

In this description, an orthopedic mattress means an independent orthopedic mattress, which is located on a solid base or on a bed frame.

Even in healthy people, there is a need to create a massage effect, uniform pressure of the mattress on the body, for better blood circulation and less stress, not to mention people who need an orthopedic mattress due to existing health problems.

Mattresses with separate independent blocks are widely known, and although they have a high level of comfort, they cannot provide a sufficient massage effect, the necessary level of load balancing on the body and the proper level of orthopedics.

The closest to the proposed utility model in technical essence is patent RU 2604175 U1, 10.12.2016, which discloses a module with air cells of an air mattress containing an air cell, including a part of the upper surface, supporting parts connected to a part of the upper surface and forming a side surface part, and a bottom surface part attached to the bottom of the supporting parts; moreover, non-contacting sections are provided on the support parts of the air cell, designed to prevent contact between adjacent air cells, a connecting section is formed on the lower edges of the support parts that protrudes outward and surrounds the lower edges of the support parts, and the connecting section and a part of the lower surface are connected by high frequency welding , communication parts are formed in the support parts of each air cell, connected to the support parts of the adjacent cell so that the air chambers formed in each air cell communicate, a part of the lower surface is made in the form of a plate element with outwardly protruding connecting elements located on the edge, and fastening holes made in the connecting elements.

The disadvantage of this device is the low orthopedic level, the uneven distribution of the load with the complexity of its design, since there is an air gap between these air chambers and the chambers tend to tilt to the side, the connecting tubes are located on the sides, which often leads to their kinks and jams (which makes it difficult to evenly redistribute between them air), and the connection of the chambers with each other by tubes in different directions also adversely affects the uniformity of the load distribution.

The purpose of this utility model is to develop a design of a self-leveling orthopedic mattress that eliminates these disadvantages.

The technical result is to increase the uniformity of load distribution of a self-leveling orthopedic mattress with a simple design.

This technical result is achieved by the fact that the self-leveling orthopedic mattress includes an external frame in the form of a rectangular parallelepiped, on the upper side of which there is an upper working plate, and on the lower side - a lower support plate,

air chambers formed by solid elastic vertical bridges, hermetically fixed to the upper working plate, lower support plate and the inner side of the outer frame, located parallel to the short side of the mattress,

the bottom support plate opposite each air chamber contains holes arranged in a row and parallel to the long side of the mattress,

wherein each of these holes is connected to a common air pipe located at the bottom, closed at one end and having a valve for inflating/lowering the air chambers from the other end.

The bottom support plate further comprises a rigid plate at the bottom having holes in correspondence with the holes in the bottom support plate.

Holes in the bottom support plate run down the center of the mattress, parallel to its long side.

Holes in the bottom base plate include rigid bushings that interact with the air tube.

The self-leveling orthopedic mattress additionally includes a compressor with a control unit for automatic pumping of air chambers through the valve for inflating / lowering the air chambers.

Further, the proposed utility model will be considered in detail, taking into account the illustration, where in Fig. 1 is a side view of a self-levelling orthopedic mattress, FIG. 2 is a top view of a self-levelling orthopedic mattress, FIG. 3 is an enlarged fragment of A from FIG. 1, where the positions indicate:

1 - outer frame;

2 - upper working plate;

3 - bottom support plate;

4 - air chambers;

5 - vertical jumpers;

6 - holes;

7 - air pipe;

8 - valve for inflating / lowering air chambers;

9 - rigid plate.

Self-leveling orthopedic mattress includes an outer frame 1 in the form of a rectangular parallelepiped. The outer frame 1 is made, as a rule, of a rigid material, wood, metal, plywood and other materials and combinations thereof, providing sufficient spatial rigidity to this frame 1 when it is used. Alternatively, the outer frame 1 can also be made of elastic materials, such as PVC, rubber and others, but it is preferable to make it from rigid materials. It is possible to use an external frame 1 (hard) with an airtight inner coating, such as rubber, to prevent air leaks from the formed air chambers 4.

On the upper side of the outer frame 1 there is an upper working plate 2 made of a flexible material capable of deforming under the weight of the human body. It is preferable to make the upper working plate 2 two or three layers, from the lower airtight material and the upper finishing material, such as velor, eco-leather, suede, etc., while, if necessary, a reinforcing layer can be placed between these layers (for example, for heavy-weight users).

On the underside of the outer frame 1, a bottom support plate 3 is placed. The bottom support plate 3 must also be made of an airtight material. This plate 3 is fixed to the inner walls of the outer frame 1, forming a closed hermetic space.

The air chambers 4 are formed by solid vertical bridges 5 located inside the outer frame 1, parallel to the short side of the mattress. These jumpers are made of an elastic material that can deform under the weight of the human body. Vertical jumpers 5 are hermetically fixed to the upper working plate 2, the lower support plate 3 and the inner side of the outer frame 1 to form air chambers 4. These jumpers 5 form a plurality of air chambers 4 that distribute the load depending on the pressure created on them by weight and anatomical features body, which increases the uniformity of load distribution in the mattress. The number and width of the air chambers 4 may vary depending on the size of the mattress, the weight load, the purpose of the mattress and other factors.

The bottom support plate 3 preferably also contains a rigid plate 9 at the bottom, which prevents distortion and deformation of the bottom support plate 3 and holes 6 in it, to increase the even distribution of the mattress load.

The bottom support plate 3, as well as the rigid plate 9 (if any) in front of each air chamber 4 contain holes 6 arranged in a row and parallel to the long side of the mattress. It is preferable to make holes 6 in the center of the mattress, parallel to its long side, which will ensure a more even distribution of the load. In this case, it is desirable to equip these holes 6 (including those with a rigid plate 9, if any) with rigid bushings (not shown in the figure), which prevent jamming of the holes 6 and further increase the uniformity of the load distribution of the self-leveling orthopedic mattress. These bushings, as a rule, are made of plastic and are fixed in holes 6, for example, by adhesive bonding.

Each of these openings 6 is connected to a common air pipe 7 located at the bottom, which connects all openings 6 of the air chambers 4 into one common air mechanism. The air pipe 7 is closed at one end and has a valve 8 for inflating/lowering the air chambers 4 at the other end. The shape and dimensions of the air pipe 7 can be different, both round and rectangular or other shapes. The air pipe 7 redistributes the air load across all air chambers 4. The air pipe 7 is made of a rigid material that prevents it from jamming. The presence, design and function of this air pipe 7 also has a positive effect on the achievement of the claimed technical result.

As a rule, a self-leveling orthopedic mattress additionally includes a compressor with a control unit (associated with the valve 8 inflating / lowering the air chambers) for automatically pumping the air chambers 4 through this valve 8 inflating / lowering the air chambers, which also increases the uniformity of the load distribution, since too much pumped cameras 4, as well as heavily deflated ones, will not ensure the correct functioning of the device.

The principle of operation of the device is as follows

The air chambers 4 of the self-leveling orthopedic mattress are inflated to a predetermined value through the inflation/deflation valve 8 of the air chambers.

The user lies down on a bed on which a self-leveling orthopedic mattress is laid.

The air chambers 4 are pressed down under the weight of the human body and its anatomical features, overcoming the air resistance in the air chambers 4, while where the pressure on the chambers is higher, the air passes (is squeezed out) into the less loaded air chambers 4 through the holes 6 in the lower support plate 3 and through the air pipe 7, which acts as an air pressure distributor in the chambers 4, thereby forming a self-levelling of the working surface of the mattress, depending on the weight load on it and the anatomical structure of the human body, which ensures the creation of a uniform load distribution of a self-leveling orthopedic mattress with a simple design.
