Abstract
Description
Technical Field
[0001] This utility model relates to the field of sponge pad technology, and more specifically to a high-resilience support composite sponge pad. Background Technology
[0002] Sponge pads are a common type of soft filling material, usually made of polyurethane foam or similar materials. They have good elasticity and shock absorption, and can provide comfortable support and cushioning. They can be used in furniture such as sofas, chairs, and mattresses to increase comfort when sitting or lying down.
[0003] To improve the resilience of the foam pad, a high-resilience PU spring foam is proposed, as shown in application number CN202210042905.X. The foam pad has a bottom surface at the top and a first groove on the bottom surface. The foam pad has a top surface at the bottom and a second groove on the top surface. A high-strength spring is provided inside the first groove.
[0004] Although the high-resilience PU spring foam mentioned above uses multiple sets of springs evenly to improve the elasticity of the foam during use, the force in the compression and recovery directions is provided only by the contact between the top and periphery of multiple springs and the foam. This results in a small rebound surface of the foam and insufficient elasticity. Utility Model Content
[0005] The purpose of this utility model is to provide a high-resilience support composite sponge pad in order to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] This utility model proposes a high-resilience support composite sponge pad, including a pad body and multiple sets of elastic elements inside it, as well as a surrounding support layer embedded in the pad body and side support layers fixed at the top and bottom ends of the multiple sets of elastic elements respectively. The periphery of the multiple sets of elastic elements is fixed to the surrounding support layer, and the side support layer is embedded in the pad body.
[0008] As a preferred technical solution of this utility model, the supporting layer and the side supporting layer divide the pad body into multiple layers from top to bottom.
[0009] As a preferred embodiment of this invention, both the supporting layer and the side supporting layer are flexible.
[0010] As a preferred embodiment of this invention, the supporting layer is more flexible than the side supporting layer.
[0011] As a preferred technical solution of this utility model, the supporting layer is provided in multiple sets and is evenly distributed from top to bottom.
[0012] As a preferred embodiment of this utility model, the supporting layer is a nylon mesh layer.
[0013] As a preferred embodiment of this utility model, the side support layer is a stainless steel wire mesh layer.
[0014] The beneficial effects of this utility model are as follows:
[0015] By adding a supporting layer and a side support layer within the pad, and fixing the side support layer at the top and bottom ends of multiple sets of elastic elements, and fixing the supporting layer at the compression periphery of multiple sets of elastic elements, when the top of the pad is compressed, the pad and multiple sets of elastic elements compress downwards. When the pressure is released, the elastic elements push against the side support layer and pull the supporting layer upwards synchronously, which increases the pull-back surface of the elastic elements on the pad, thereby improving resilience. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of this utility model.
[0017] Reference numerals: pad-1, elastic element-2, supporting layer-3, side supporting layer-4. Detailed Implementation
[0018] like Figure 1 As shown, this utility model proposes: a high-resilience support composite sponge pad, including a pad body 1 and a plurality of elastic elements 2 inside it; the elastic elements 2 can be cylindrical spiral elastic with their elastic ends facing up and down, and a plurality of cavities are evenly opened inside the pad body 1 to accommodate the plurality of elastic elements 2 one by one.
[0019] It also includes a supporting layer 3 embedded in the pad body 1 and side supporting layers 4 fixed to the top and bottom ends of multiple sets of elastic members 2 respectively. The periphery of the multiple sets of elastic members 2 is fixed to the supporting layer 3 respectively, and the side supporting layer 4 is embedded in the pad body 1.
[0020] By additionally setting a supporting layer 3 and a side supporting layer 4 in the pad body 1, and fixing the side supporting layer 4 at the top and bottom ends of the multiple sets of elastic elements 2 respectively, and fixing the supporting layer 3 at the compression periphery of the multiple sets of elastic elements 2, when the top of the pad body 1 is compressed, the pad body 1 and the multiple sets of elastic elements 2 are compressed downward. When the pressure is released, the elastic elements 2 push against the side supporting layer 4 and pull the supporting layer 3 to return upward synchronously, which can increase the pull surface of the elastic elements 2 on the pad body 1, thereby improving the resilience.
[0021] Among them, the supporting layer 3 and the side supporting layer 4 divide the pad body 1 into multiple layers from top to bottom; as shown in the figure, the ends of the supporting layer 3 and the side supporting layer 4 face up and down, and each supporting layer 3 or side supporting layer 4 cuts the pad body 1 up and down. In this way, the supporting layer 3 or the side supporting layer 4 can improve the overall support and stability when in use.
[0022] Specifically: The set support layer 3 and side support layer 4 not only provide additional support, but also increase the overall stability of the mattress 1, and restrict multiple elastic positions, making the whole structure more stable and reducing the deformation and displacement of the mattress during use;
[0023] Furthermore, the connection of the supporting layer 3, the side supporting layer 4, and the elastic element 2 into one unit can evenly distribute the pressure, thereby reducing the pressure directly borne by the elastic element 2 and extending its service life.
[0024] Among them, the supporting layer 3 and the side supporting layer 4 are both soft; they can better adapt to the multi-directional deformation of the pad body 1 and improve comfort.
[0025] The supporting layer 3 is more flexible than the side supporting layer 4, so that the side supporting layer 4 can provide better vertical support stability to the elastic element 2, thereby enhancing the structural stability during frequent activities.
[0026] The supporting layer 3 has multiple sets that are evenly distributed from top to bottom. These multiple sets are evenly connected to the compression periphery of the elastic element 2, which can further improve the pull-back surface of the pad 1 and enhance its resilience.
[0027] The supporting layer 3 is a nylon mesh layer or a spandex mesh layer. Both the nylon mesh layer and the spandex mesh layer are woven from the corresponding fibers. The nylon mesh layer has good durability and tear resistance, while the spandex mesh layer has good wear resistance and anti-aging properties, resulting in a long service life. In addition, the nylon mesh layer or the spandex mesh layer has a certain degree of elasticity, which can better adapt to the elastic element 2 during rebound and compression, and provides good protection.
[0028] The side support layer 4 is a stainless steel wire mesh layer. Stainless steel wire mesh has very high strength and corrosion resistance, and can provide durable support. The stainless steel wire mesh layer is made of corresponding stainless steel wire and can be made by using a coarser or denser weave to provide less flexibility than the support layer 3.
[0029] Supplementary information: Based on the structure of the aforementioned high-resilience support composite sponge pad, the manufacturing method of the sponge pad is as follows: The pad body 1 is pre-divided into multiple overlapping layers from top to bottom. Except for the top and bottom overlapping layers, receiving openings are provided at both ends of the remaining overlapping layers. After the multiple overlapping layers are attached from top to bottom, the receiving openings form a cavity. The structure after combining the multiple overlapping layers, the supporting layer 3, the side supporting layer 4, and multiple sets of elastic elements 2 is as follows: Figure 1 As shown, multiple overlapping layers and supporting layers 3 or side supporting layers 4 can be fixed together by means of bonding, etc., and elastic element 2 and side supporting layer 4 can be fixed together by means of bonding or welding, etc.
