Description

[01] Field of technology

[02] The utility model relates to furniture structures, namely to a pendulum support (support pendulum) for transformable furniture for sitting and lying, and can be used in the structures of sofas or Eurobook-type chairs, in which transformation leads to an increase in the size of the sleeping area due to the rotation of the back and horizontal movement of the seat.

[03] State of the Art

[04] In Eurobook type sofa beds with a metal frame, the seat and backrest frames usually use snake springs, which weaken the load-bearing capacity of the frames, especially in the middle part of the furniture. Accordingly, it becomes necessary to support the middle part of the frame structure (at the junction of the backrest and seat frames) by resting the transformation mechanism on the linen box.

[05] The closest analogue of the utility model is a roller support for transformable furniture, disclosed in the Russian Federation patent RU 2266697, 27.12.2005. This support comprises a housing having an element for a hinged connection with the frame of a horizontally movable seat of the furniture, ensuring the possibility of rotating the housing by an angle of 90° when the movable hook of the furniture acts on it, as well as a support surface designed with the possibility of resting on the floor. The disadvantage of the analogue is that the support only provides support for the seat frame in the unfolded state without supporting the back frame, and is not used in any way in the folded state. This does not fully prevent the sagging of the frames in the folded and unfolded states of the furniture.

[06] Thus, the main technical problem that the utility model is aimed at solving is the narrow functional capabilities of the support when used in transformable furniture and, as a consequence, the reduced rigidity of the structure of such furniture in the folded and unfolded states.

[07] Disclosure of the essence of the utility model

[08] The technical result of the utility model is the expansion of the support functions of the pendulum support due to the possibility of simultaneously supporting the back and seat frames in the unfolded state of the furniture and supporting the seat frame in the folded state.

[09] The specified technical result is achieved in the claimed utility model due to the fact that the pendulum support for transformable furniture includes a housing that has hinged fastenings for connection to the mechanism for transforming the frame of the horizontally movable seat of the furniture with the ability to pivotally move the housing between the first position corresponding to the folded state of the furniture and the second position corresponding to the unfolded state of the furniture, as well as a support surface. The housing is designed with the ability to pivot from the first position to the second position when interacting with the protruding elements of the linen box of the furniture and to move from the second position to the first due to its own weight. The support surface of the housing is designed with the ability to rest on the linen box in the first position and on the protruding elements of the linen box in the second position. In this case, the housing additionally has a stop surface designed with the ability to support the rotary frame of the back in the second position.

[010] In particular embodiments of the utility model:

[011] - the body is formed by two end elements connected to each other by two longitudinal elements that form the base of the body;

[012] - the end elements are made in the form of triangles, wherein the supporting surface of the housing is formed on the side of the base and the side, and the thrust surface is at the top adjacent to the base, wherein the hinge fasteners are located at the top opposite the base of the housing.

[013] - the body is designed to rotate at an angle of 45°.

[014] Unlike similar support elements, the claimed pendulum support provides support for both the backrest frame and the seat frame of the transformable furniture due to the rotary structure, equipped with support and thrust surfaces. As a result, the support functions of the frame furniture are expanded, and the rigidity of the furniture frame is increased. In addition, the design is simple, since it operates due to natural gravity without the use of springs and other additional parts.

[023] Implementation of a utility model

[024] The claimed pendulum support has an elongated body (1) which is installed across the furniture frame. The body (1) is preferably formed by two end elements (2) which are connected at the bottom by two longitudinal elements (3) in the form of beams forming the base of the body. The end elements (2) are preferably shaped as a right triangle in which the lower and one side form legs, and the other side forms the hypotenuse. The said end elements (2) may have openings in the center. The body (1) may also have another design, for example, be made in the form of a single piece of a suitable shape.

[025] The housing (1) is provided with two hinged fastenings (4), at least one support surface (5) and at least one thrust surface (6).

[026] The hinge fastenings (4) are made in the form of holes for installing an axis and provide a connection of the body (1) with the transformation mechanism (11) of the frame (8) of the furniture seat on a metal frame. In a particular embodiment of the body (1), shown in Fig. 1, the hinge fastenings are made in the upper part of the end elements (2), formed by the projection of the apex of the triangle opposite the base of the body. The said hinge connection provides the body (1) with the possibility of rotary movement, in particular at an angle of 45° or more, between the first position, corresponding to the folded state of the furniture (Fig. 2), and the second position, corresponding to the unfolded state of the furniture (Fig. 3).

[027] The support surface (5) provides the possibility of resting the body (1) on the laundry box (9) in the first position (Fig. 4) and on the protruding element (10) of this box (9) in the second position (Fig. 5). In a particular case of implementing the utility model, the support surface (5) is formed by a base (lower part) and a side part of the body, lying in the planes of the legs of the triangles of the end elements (2). In the first position (Fig. 5), the body rests on the base formed by the lower legs of the end elements (2) and the transverse elements, and in the second position (Fig. 4), the body rests, to a greater extent, on the side part (side leg), formed by the flanging of the end elements (2) and one transverse element (3).

[028] To move the body (1) from the first position to the second and to hold it in the second position, two protruding elements (10) are provided on the linen drawer (9), which are preferably made in the form of curved strips attached to the side walls of the drawer (9). The curved ends of the elements (10) preferably protrude above the upper edge of the linen drawer (9).

[029] The supporting surface (6) is intended to support the rotating frame (7) of the backrest in the second position of the furniture. This surface, in a particular case of implementation, is formed by the protruding part of the top of the end elements (2) and one transverse element (3) at the base of the body (1).

[030] It will be obvious to a person skilled in the art that other embodiments of the housing (1) are possible, including its support (5) and stop (6) surfaces, as well as the projections (10) of the laundry box, which will correspond to the shape of the housing (1). In particular, the housing (1) can have a profile of a triangular, quadrangular (trapezoidal, etc.) or a more complex shape with rectilinear or curved sides. The key is the presence of support and stop surfaces, and their size, shape and location can be different. Also, depending on the shape, the angle of rotation of the housing (1) can change.

[031] The pendulum support operates as follows. The support body (1) is attached to the left and right parts of the transformation mechanisms (11), connected to the seat frame (8). In the folded position (Fig. 4) of the furniture, the backrest frame (7) is located essentially vertically, and the horizontal seat frame (8) adjoins the backrest frame and, through the elements of the transformation mechanism (11), rests on the hinged fastenings (4) of the support body (1), which in turn rests with its base with the support surface (5) on the linen box (9). When the furniture is unfolded (Fig. 5), the seat frame (8) moves in the horizontal direction (along an arcuate trajectory) from the backrest, wherein the protruding element (10) of the linen box (9) turns the support body (1) on its side and holds it in the second position. The backrest frame (7) is lowered into the horizontal plane of the seat frame (8) onto the stop surface (6) of the body. As a result, the seat frame (8) is supported by the hinged mount (4) of the body (1), and the back frame by its support surface (6). At the same time, the body itself rests on the protruding elements (10) of the linen box (9). When folding the furniture, the body (1) rotates from the second position to the first due to gravity.

[032] Thus, the support pendulum provides rigid support of the frames on the laundry box both in the folded position (seat frame) and in the unfolded position (both frames).
