Description

Technical Field

[0001] The utility model relates to the technical field of household articles, in particular to a foldable and storable bed cushion. Background Art

[0002] Cushions are indispensable fabric products in the bedroom. They not only provide people with comfortable support, but also have a decorative effect that cannot be replaced by other items. Cushions can adjust the contact point between the human body and the seat or bed to obtain a more comfortable angle to reduce fatigue. Due to the convenience and flexibility of cushions, they are widely used on beds and sofas in the bedroom. At present, most cushions used in beds are large in structure and need to occupy a large amount of external space when stored, which makes storage very inconvenient. Utility Model Content

[0003] The technical problem to be solved by the utility model is that most of the cushions currently used on beds are of large structure and need to occupy a large amount of external space when stored, which makes the storage very inconvenient.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a foldable and storable bed cushion, comprising a main support frame with an inverted V-shaped structure and a cushion body filled with silicone, the main support frame comprising a first support plate, a second support plate, a first end connecting frame fixed to the connecting end of the first support plate, a second end connecting frame fixed to the connecting end of the second support plate, and a transverse assembly shaft movably connected between the first end connecting frame and the second end connecting frame, a middle limiting frame movably sleeved on the transverse assembly shaft, and strip fixing openings for installing the cushion body and the middle limiting frame are fixed on the outer sides of the first support plate and the second support plate.

[0005] The upper end of the middle limiting frame is provided with a third end connecting frame matched with the transverse assembly shaft.

[0006] An internal flip opening is provided inside the middle limit frame, and a flip limit plate is movably installed inside the internal flip opening via a rotating shaft.

[0007] A strip-shaped assembly block matched with the strip-shaped fixing opening is fixedly assembled on the side wall of the connecting surface of the cushion body.

[0008] The flip limit plate and the two side ends of the strip assembly block are provided with lateral protrusions for improving the firmness of assembly with the strip fixing opening.

[0009] The first end connecting frame, the second end connecting frame and the third end connecting frame are sleeved on the transverse assembly shaft in an offset manner.

[0010] The beneficial effects of the utility model are:

[0011] (1) The foldable and storable bed cushion of the utility model adopts a flippable structural design, which can be unfolded when in use and retracted when stored, thereby greatly reducing its external structure in the stored state, making storage convenient;

[0012] (2) The entire cushion adopts a detachable structure design, which is convenient for processing and production, and also convenient for subsequent cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 It is a structural schematic diagram of the utility model in the storage state.

[0015] Figure 2 It is a schematic diagram of the internal structure of the utility model in the storage state.

[0016] Figure 3 It is a structural schematic diagram of the utility model in an unfolded state. DETAILED DESCRIPTION

[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Figure 1 , Figure 2 and Figure 3 A foldable and storable bed cushion is shown, comprising a main support frame with an inverted V-shaped structure and a cushion body 1 filled with silicone, the main support frame comprising a first support plate 2, a second support plate 3, a first end connecting frame 4 fixed to the connecting end of the first support plate 2, a second end connecting frame 5 fixed to the connecting end of the second support plate 3, and a transverse assembly axis 6 movably connected between the first end connecting frame 4 and the second end connecting frame 5, a middle limit frame 7 is movably sleeved on the transverse assembly axis 6, and strip fixing openings 8 for mounting the cushion body 1 and the middle limit frame 7 are fixed on the outer sides of the first support plate 2 and the second support plate 3.

[0020] In order to cooperate with the middle movable assembly, the upper end of the middle limit frame 7 has a third end connecting frame 9 that cooperates with the transverse assembly shaft 6.

[0021] In order to facilitate the fixing and limiting of the angles of the first support plate 2 and the second support plate 3 , an internal flip opening 10 is provided inside the middle limit frame 7 , and a flip limit plate 11 is movably installed inside the internal flip opening 10 via a rotating shaft.

[0022] In order to facilitate fixing, assembling and disassembling, a strip-shaped assembly block 12 matching with the strip-shaped fixing opening 8 is fixedly assembled on the side wall of the connecting surface of the cushion body 1 .

[0023] In order to improve the assembly firmness, both side ends of the flip limit plate 11 and the strip assembly block 12 are provided with lateral protrusions for improving the assembly firmness with the strip fixing opening 8 .

[0024] In order to facilitate assembly, the first end connecting frame 4 , the second end connecting frame 5 and the third end connecting frame 9 are sleeved on the transverse assembly shaft 6 in an offset manner.

[0025] Adjustment principle: the cushion body 1 is inserted into the strip fixing opening 8 and fixedly assembled with the first support plate 2 and the second support plate 3 through the strip fixing block 12 at the assembly end. The cushion body 1 can also be disassembled for replacement or cleaning. When the angles of the first support plate 2 and the second support plate 3 need to be adjusted, it is only necessary to flip the first support plate 2 and the second support plate 3 outward, and then flip the flip limiting plate 11 inside the middle limit frame 7 horizontally, and then insert the two ends of the flip limiting plate 11 into the strip fixing opening 8 of the first support plate 2 and the second support plate 3 respectively, so that the angles of the first support plate 2 and the second support plate 3 are fixed. The two ends of the flip limiting plate 11 have inclined assembly sections that match the strip fixing opening 8, which are very convenient for fixing with the first support plate 2 and the second support plate 3.

[0026] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
