Description

Technical Field

[0001] The present application relates to the technical field of pads, and in particular to a supporting pad. Background Art

[0002] Sofas and beds are essential furniture pieces in modern life, and continuous refinement of their design and manufacturing technologies is crucial to enhancing home comfort. In both traditional and modern technologies, the basic structure of a sofa and bed typically consists of a stable frame and a resilient cushion (specifically, a mattress or sofa cushion) placed atop it. These cushions are typically filled with sponge and covered in carefully selected fabric or leather, ensuring a soft and comfortable sitting and lying experience.

[0003] However, in actual use, especially when sofas or beds are frequently used for extended periods of sitting or lying, specific areas of the main frame may experience structural sag or deformation due to long-term pressure. This phenomenon can lead to a decrease in the furniture's support performance, failing to meet the user's basic needs for comfort and health support. This structural collapse is particularly prominent in high-load usage scenarios, such as sofas in the living room or beds in the master bedroom, and there is room for improvement. Summary of the Invention

[0004] The purpose of this application is to provide a support pad to solve the problem in the above-mentioned related art that the main body may become dented or deformed after being under pressure for a long time.

[0005] The support pad provided in this application adopts the following technical solution:

[0006] A support pad comprises a plurality of parallel bags and a core plate located in the bags. The edges of the bags are fixed with connecting pieces, and adjacent bags are fixedly connected by the connecting pieces. The bags can be folded or unfolded along the connecting pieces.

[0007] By adopting the above technical solution, when the support pad is used, due to the foldable setting of the bag body, several bags can be spread out along the connecting piece, and the expanded support pad can be placed under the mattress or sofa cushion to enhance the pressure-bearing and supporting performance of the bed and sofa body below; and when it is not needed, the user can also fold and store the support pad.

[0008] Optionally, the core board includes two relatively plugged-in card boards, one end of each card board is fixed with a positioning block and a positioning slot; the positioning block on one card board can be inserted into the positioning slot on the other card board.

[0009] By adopting the above technical solution, due to the split setting of the core board, two card boards can be spliced ​​into a core board, so that the positioning plug on one of the card boards can be inserted into the positioning slot on the other card board along its own guide slope. Each core board or card board can be disassembled and replaced independently, which is convenient for subsequent maintenance and upgrades.

[0010] Optionally, a guiding slope is provided on the side edge of the positioning block away from the clamping plate.

[0011] By adopting the above technical solution, during the process of inserting the positioning block into the positioning slot, due to the setting of the guiding bevel, the positioning block is easily inserted into the corresponding positioning slot along the guiding bevel, thereby improving the splicing efficiency of the two card boards.

[0012] Optionally, an elastic clamping piece is provided on the positioning plug block, and a positioning groove for inserting the elastic clamping piece is provided on the inner wall of the positioning slot.

[0013] By adopting the above technical solution, when the positioning block is inserted into the positioning slot, the elastic clip on the positioning block is simultaneously inserted into the positioning groove on the inner wall of the positioning slot, thereby improving the stability of the two card boards after splicing.

[0014] Optionally, guide arc surfaces are provided on the side edges of the two clamping plates that are away from each other.

[0015] By adopting the above technical solution, due to the provision of the guiding arc surface on the edge of the card board, it is convenient to put the assembled card board into the bag body.

[0016] Optionally, a plurality of anti-slip convex strips are fixedly provided on two opposite sides of the card plate.

[0017] By adopting the above technical solution, due to the setting of the anti-slip ridges, after the core board is installed inside the bag body, the possibility of relative sliding of the core board inside the bag body is reduced, thereby improving the installation stability of the core board in the bag body.

[0018] Optionally, the outer side surface of the anti-slip convex strip is a curved surface.

[0019] By adopting the above technical solution, the possibility of the anti-slip convex strips scratching the inner wall of the bag body is reduced.

[0020] Optionally, a flexible rope is fixed on the outer side of the bag body at the outermost edge, and the flexible rope can be wrapped around the entire outside of the bag body when the bag bodies are in a folded state.

[0021] By adopting the above technical solution, when several bags are in a folded state, due to the setting of the flexible rope on the bag body, the flexible rope can be wrapped around the outside of the bag as a whole, preventing the support pad in the folded state from automatically spreading out in a natural state, thereby improving the stability of the support pad in the folded state.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Due to the foldable setting of the bag body, when the support pad is used, several bags can be spread out along the connecting piece, and the unfolded support pad can be placed under the mattress or sofa cushion to enhance the pressure-bearing and support performance of the bed and sofa body below; and when it is not needed, the user can also fold and store the support pad.

[0024] 2. Due to the split setting of the core board, two card boards can be spliced ​​into a core board, so that the positioning plug on one card board can be inserted into the positioning slot on the other card board along its own guide slope. Each core board or card board can be disassembled and replaced independently, which is convenient for subsequent maintenance and upgrades. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 A support pad includes a plurality of bags 1 parallel to each other, a hard core board 2 located in the bag 1, a connecting piece 11 fixed on the edge of the bag 1, and adjacent bags 1 are fixedly connected by the connecting piece 11, wherein the bag 1 and the connecting piece 11 are made of canvas or Oxford cloth;

[0035] When the support pad is assembled, an opening is pre-set on the bag body 1. After the core board 2 is placed into the bag body 1 from the opening, the opening is sewed with needle and thread; when the support pad is used, several bag bodies 1 can be spread out along the connecting piece 11; when the support pad is packaged for transportation, several bag bodies 1 can be folded and stored along the connecting piece 11.

[0036] The implementation principle of the embodiment of this application is:

[0037] When the support pad is used, several bags 1 can be spread out along the connecting piece 11, and the unfolded support pad can be placed under the mattress and sofa cushion to enhance the pressure-bearing performance of the bed and sofa body below; when not needed, the support pad can be folded and stored.

[0038] Example 2:

[0039] Reference Figure 3 The difference between the embodiment of the present application and embodiment 1 is that a flexible rope 12 is fixedly provided on the outer surface of the bag body 1 at the outermost edge, wherein the flexible rope 12 is made of nylon. The flexible rope 12 can be wrapped around the entire outside of the bag bodies 1 when they are in a folded state, thereby preventing the support pads in the folded state from automatically spreading out in a natural state.

[0040] Reference Figure 4 The core board 2 includes two relatively plugged-in card boards 21, wherein a positioning block 211 is fixedly provided at one end of the card board 21, a positioning slot 212 is opened, and a guiding slope 2112 is provided on the side edge of the positioning block 211 away from the card board 21; between the two relatively card boards 21, the positioning block 211 on any card board 21 can be inserted into the positioning slot 212 on the other card board 21 along its own guiding slope 2112, thereby realizing the mutual plugging of the two card boards 21.

[0041] Reference Figure 4 and Figure 5The positioning plug 211 is provided with an elastic clip 22, wherein the elastic clip 22 includes a compression spring 221 and an arc-shaped protrusion 222. The positioning plug 211 is provided with a placement groove 2111 for the compression spring 221 and the arc-shaped protrusion 222 to be placed. The compression spring 221 squeezes the arc-shaped protrusion 222 so that a part of the arc-shaped protrusion 222 protrudes from the opening of the placement groove 2111. The outer side surface of the protruding part is an arc surface, and the arc length corresponding to the arc surface is a minor arc. At the same time, a positioning groove 2121 is provided on the inner wall of the positioning slot 212 for the protruding part of the arc-shaped protrusion 222 to be inserted.

[0042] Reference Figure 4 A plurality of anti-slip ridges 213 are integrally formed on opposite sides of the clamping plate 21, and the outer surfaces of the anti-slip ridges 213 are curved. After the core plate 2 is installed in the bag body 1, the anti-slip ridges 213 reduce the possibility of the core plate 2 sliding relative to the bag body 1. At the same time, the curved outer surfaces of the anti-slip ridges 213 also reduce the possibility of the anti-slip ridges 213 scratching the inner wall of the bag body 1.

[0043] Reference Figure 4 A guide arc surface 214 is provided on the side edges of the two card plates 21 that are away from each other, which facilitates the assembly of the card plates 21 into the bag body 1 and improves the overall assembly efficiency of the support pad.

[0044] The implementation principle of the embodiment of this application is:

[0045] When the core panels 2 are joined, the positioning block 211 on one of the card panels 21 can be inserted into the positioning slot 212 on the other card panel 21 along its own guiding slope 2112. Simultaneously, the elastic clip 22 on the positioning block 211 is inserted into the positioning groove 2121 on the inner wall of the positioning slot 212, thereby achieving the mutual insertion of the two card panels 21. The split design of the core panels 2 provides greater flexibility. Each core panel 2 or card panel 21 can be removed and replaced independently, facilitating maintenance and upgrades.
