Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a bending support device. Background Technology

[0002] Elastic support structures such as cushions and mattresses are commonly used in furniture to improve the comfort of the human body.

[0003] Currently, there are many electric furniture products on the market, such as electric sofas and electric beds, which can perform operations such as angle adjustment, folding, and backrest lifting. At this time, the elastic support structure will bend. Traditional elastic support structures are difficult to adapt to long-term bending operations. Long-term bending will damage the mattress filling material, reduce the service life, and the elastic support structure is prone to detaching from the main body of the electric furniture when bending.

[0004] Therefore, there is an urgent need for a bending support device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a bending support device that can reduce the risk of bending damage, extend service life, and prevent the bending support device from detaching from the support device.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A bending support device is provided, comprising:

[0008] A first elastic support layer is used to at least partially support the human body; a plurality of first grooves are provided on a first surface of the first elastic support layer near the human body, and the plurality of first grooves are spaced apart along the length direction of the first surface.

[0009] A second elastic support layer is used to support the first elastic support layer; the first elastic support layer is stacked on top of the second elastic support layer, and the second elastic support layer is installed on the support device.

[0010] A positioning groove is provided for positioning the support device; the positioning groove is disposed on the second surface of the second elastic support layer near the support device.

[0011] When the bending support device is installed on the leaning device, the positioning groove at least partially accommodates the mounting frame on the leaning device; when the bending support device is in a bent state, at least one of the first grooves deforms.

[0012] As an optional technical solution, the resilience of the second elastic support layer is greater than that of the first elastic support layer.

[0013] As an optional technical solution, the hardness of the second elastic support layer is greater than that of the first elastic support layer.

[0014] As an optional technical solution, the second elastic support layer is provided with a plurality of second grooves on the second surface near the abutment device, and the plurality of second grooves are spaced apart along the length direction of the second surface.

[0015] As an optional technical solution, the first groove extends along the width direction on the first surface of the first elastic support layer.

[0016] As an optional technical solution, the second groove extends along the width direction on the second surface of the second elastic support layer.

[0017] As an optional technical solution, the depth of the first groove is less than the depth of the second groove.

[0018] As an optional technical solution, the second elastic support layer is provided with a plurality of third grooves on the second surface near the abutment device, and the plurality of third grooves are spaced apart along the length direction of the second surface.

[0019] As an optional technical solution, the third groove extends along the width direction on the second surface of the second elastic support layer.

[0020] As an optional technical solution, the depth of the third groove is less than the depth of the second groove.

[0021] The beneficial effects of this utility model are:

[0022] The bending support device provided by this utility model includes a first elastic support layer and a second elastic support layer distributed vertically.

Furthermore, a first groove is provided on the upper surface of the first elastic support layer, and a second groove is provided on the lower surface of the second elastic support layer. When the support device adjusts its angle or is raised, the first groove is compressed and contracts, allowing the bending support device to adapt to compression and deform, reducing the squeezing effect on the bending support device during the support device's operation and extending its service life. Moreover, by providing a positioning groove on the second surface of the second elastic support layer to cooperate with the mounting frame on the support device, the bending support device remains connected to the support device, preventing the bending support device from detaching from the support device.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] Please refer to Figures 1-3 This embodiment provides a bending support device for installation on a sofa frame, bed frame, or other support device 1000, providing elastic and flexible support for the user. The bending support device includes a first elastic support layer 10 and a second elastic support layer 20. The first elastic support layer 10 is stacked on top of the second elastic support layer 20. The first elastic support layer 10 is used to at least partially support the human body, and the second elastic support layer 20 is used to support the first elastic support layer 10.

[0037] For further details, please refer to Figures 1-3 The first elastic support layer 10 has a plurality of first grooves 1 on its first surface 11 near the human body, and the plurality of first grooves 1 are spaced apart along the length direction of the first surface 11. Additionally, the second elastic support layer 20 has a positioning groove 30 on its second surface 21 near the support device 1000, and the positioning groove 30 is used for positioning on the support device 1000. When the bending support device is installed on the support device 1000, the positioning groove 30 at least partially accommodates the mounting frame 1100 on the support device 1000; when the bending support device is in a bent state, at least one of the first grooves 1 deforms.

[0038] Specifically, the bending support device provided in this embodiment includes a first elastic support layer 10 and a second elastic support layer 20 distributed vertically. By setting a multi-layer structure, the stress during bending can be dispersed, and micro-sliding space between layers can be retained, which can reduce the risk of bending damage. In addition, a first groove 1 is provided on the upper surface of the first elastic support layer 10, and a second groove 2 is provided on the lower surface of the second elastic support layer 20. When the leaning device 1000 adjusts the angle or lifts, the first groove 1 is squeezed and contracts, so that the bending support device can adapt to the compression and deform, reducing the squeezing effect on the bending support device when the leaning device 1000 moves, and extending the service life. Furthermore, by providing a positioning groove 30 on the second surface 21 of the second elastic support layer 20 to cooperate with the mounting frame 1100 on the leaning device 1000, the bending support device is kept connected to the leaning device 1000, preventing the bending support device from detaching from the leaning device 1000.

[0039] For example, the number, shape and position of the positioning grooves 30 on the second surface 21 can be selectively set according to the mounting frame 1100 on the leaning device 1000.

[0040] For example, the positioning groove 30 extends along the length direction on the second surface 21 and is recessed inward on the second surface 21.

[0041] For example, please refer to Figure 1 The first groove 1 extends along the width direction on the first surface 11 of the first elastic support layer 10. Optionally, the first groove 1 penetrates through the first surface 11 of the first elastic support layer 10 along the width direction, so as to fully deform during bending of the bending support device and reduce the material impact of compression on the body of the first elastic support layer 10.

[0042] For example, please refer to Figure 1 The second elastic support layer 20 is provided with a plurality of second grooves 2 near the second surface 21 of the support device 1000, and the plurality of second grooves 2 are spaced apart along the length direction of the second surface 21. When the support device 1000 adjusts the angle or is raised, the second grooves 2 are stretched and expanded, so that the bottom surface of the bending support device can adapt to the stretching and deform, thereby reducing the stretching effect of the support device 1000 on the bending support device when it is in motion.

[0043] For example, please refer to Figure 1 The second groove 2 extends along the width direction on the second surface 21 of the second elastic support layer 20. Optionally, the second groove 2 penetrates through the second surface 21 of the second elastic support layer 20 along the width direction to fully deform during bending of the bending support device, thereby reducing the tensile impact on the material of the second elastic support layer 20 body.

[0044] For example, please refer to Figure 1 The depth of the first groove 1 is less than the depth of the second groove 2, so as to reduce the degree of concavity of the first surface 11 of the first elastic support layer 10, reduce the impact of the first groove 1 on the bending support device supporting the human body, and ensure the user experience.

[0045] For example, please refer to Figure 1 The second elastic support layer 20 is provided with a plurality of third grooves 3 near the second surface 21 of the abutment device 1000. The plurality of third grooves 3 are spaced apart along the length direction of the second surface 21. Specifically, the plurality of third grooves 3 are staggered with the plurality of second grooves 2. When the abutment device 1000 adjusts its angle or is raised, the third grooves 3 are stretched and expanded, so that the bottom surface of the bending support device can adapt to the stretching and deform, thereby reducing the stretching effect of the abutment device 1000 on the bending support device when it operates.

[0046] For example, please refer to Figure 1The depth of the third groove 3 is less than the depth of the second groove 2. It can be understood that on the second surface 21 of the second elastic support layer 20, the second groove 2 and the third groove 3 of different depths are alternately arranged. The combination of alternating deep grooves (second groove 2) and shallow grooves (third groove 3) provides better support and is less prone to tearing than using only deep grooves (second groove 2). This can improve the overall durability and support comfort of the bending support device.

[0047] For example, please refer to Figure 1 The third groove 3 extends along the width direction on the second surface 21 of the second elastic support layer 20. Optionally, the third groove 3 penetrates through the second surface 21 of the second elastic support layer 20 along the width direction to fully deform during bending of the bending support device and reduce the tensile impact on the material of the second elastic support layer 20 body.

[0048] For example, the rebound rate of the second elastic support layer 20 is greater than that of the first elastic support layer 10. As the upper layer, the lower rebound rate of the first elastic support layer 10 can significantly increase the contact area between the human body and the bending support device, dispersing local point pressure into more uniform surface pressure, effectively reducing local pressure, providing a "floating" or "wrapping" feeling, and effectively absorbing and dissipating vibrations and impacts caused by minor body movements; while the higher rebound rate of the second elastic support layer 20, as the lower support structure, can provide higher structural strength and more stable support, preventing the human body from sinking too much and increasing the upper limit of support force.

[0049] For example, the second elastic support layer 20 has a harder hardness than the first elastic support layer 10. On the one hand, the first elastic support layer 10 provides soft support for the user, and on the other hand, the second elastic support layer 20 provides stronger support for the first elastic support layer 10, giving the user a support that is both soft and resilient.

[0050] For example, the first elastic support layer 10 is made of slow rebound sponge.

[0051] For example, the second elastic support layer 20 is made of ordinary polyurethane foam or high-resilience foam.

[0052] For example, the first elastic support layer 10 and the second elastic support layer 20 are fixed together by adhesive.

[0053] For example, please refer to Figure 1 Multiple bending zones 100 are provided along the length of the bending support device. The bending zones 100 are provided corresponding to the bendable parts of the support device 1000. The first groove 1, the second groove 2 and the third groove 3 are all provided in the bending zones 100.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
