Description

[0001] Movable seat platform

[0002] The invention relates to the field of office and home furniture, namely to devices for creating comfort during long periods of work at a computer and preventing diseases of the musculoskeletal system.

[0003] An overhead seat for furniture (RU 106512 U1) is known, containing two platforms between which a hinge and a support plate with a rounded profile are located. With respect to these elements, the platforms have the ability to be positioned at different angles under the weight of a person when he or she moves.

[0004] The disadvantage of this utility model is that the platforms are not securely fixed relative to each other and they lack an element of resistance to deflection.

[0005] A health chair (RU 93641 U1) is known, in which the seat support surfaces are made of a bent element with springing divided into two parts. This manufacturing method ensures separate support of the body when sitting.

[0006] The disadvantage of this useful model is that the method of manufacturing such a chair is very complex and in case of breakage of one of the parts it is subject to complete replacement. Also, this useful model limits the seating area of ​​a person by the need to be between separate parts.

[0007] A movable joint for a seat is known (RU 2301007 C2) consisting of two support surfaces and connected to each other by means of a shaft, relative to the axis of which they can rotate. The rotation is limited by elastic plate elements and a projection on one of the support surfaces.

[0008] The disadvantage of this invention is the presence of parts that are difficult to manufacture. And also the limitation of the movement of a person sitting on a chair only by changing the position of the body due to rotation relative to the axis of the shaft.

[0009] The technical task of the invention is to create a movable seat platform that can be installed on a chair and provide the ability to sit in different positions, including for people with different anatomical features.

[0010] The technical result is to provide support for the body of the person sitting in any position due to uniform fit in the seat area.

[0011] The problem is solved, and the technical result is achieved by a movable seat platform containing left and right parts of the lower and upper platforms, connected to each other through an elastic plate by means of a threaded or other detachable connection.

[0012] According to the invention, the movable seat platform can be secured to the chair with a detachable connection through holes in the platforms.

[0013] The essence of the invention is explained by drawings of a specific example of the implementation of a movable seat platform, where Fig. 1 shows a movable seat platform, and Fig. 2 shows a general view of the chair.

[0014] The movable seat platform comprises the left part of the lower platform 1, the right part of the lower platform 2, the left part of the upper platform 3, the right part of the upper platform 4 and the elastic plate 5, connected to each other by means of a detachable connection 6. The left part of the lower platform 1 is a mirror image of the right part of the lower platform 2 and consists of a lower corner 7, a short tube 8 and a rear plate 9 connected to each other by a permanent connection. The left part of the upper platform 3 is a mirror image of the right part of the upper platform 4 and consists of an upper corner 10, a long tube 11 and a front plate 12 connected to each other by a permanent connection. The lower corners 7 and upper 10 have openings through which they are connected to the seat and the seat support. In the current version of the design, nuts are welded to the corners along the axis of the opening for fixation using a threaded connection.

[0015] In this case, the elastic plate 5 is installed in the amount of 1 piece, but several pieces can be installed close together or with washers installed between them.

[0016] The lower 7 and upper 10 corners have a L-shaped profile in section. In other design options, it is possible to use the lower 7 and upper 10 corners with any other profile in section (for example, U-shaped), allowing the unit to be secured to the chair.

[0017] Thus, the claimed invention provides a reliable movable seat platform that can be installed on a chair and provide support for the seat in any position.
