Description

Technical Field

[0001] The present invention relates to the field of elastic pads, and in particular to an elastic module and an elastic pad with a large supporting area. Background Art

[0002] Mattresses and other furniture items are becoming increasingly common in people's lives. With the development of modern life, mattresses and other furniture increasingly need to be able to be disassembled and assembled to accommodate population mobility and outdoor leisure needs. However, existing mattresses are typically integrated with multiple layers and springs, resulting in large overall dimensions and difficulty in disassembly and storage.

[0003] Existing mattresses also have the disadvantage of being difficult to clean. Typically, only the covers are removable, while the sponge is not. This makes cleaning difficult. Even though latex may offer some mite resistance, mattresses often last for years, and the difficult-to-clean sponge poses a significant health risk.

[0004] Therefore, it is necessary to provide a detachable elastic pad that allows the springs to be detached from the mounting bracket of the elastic pad. When the springs and the mounting bracket are independently detachable, there is a certain gap between each independent spring. During long-term use, the density and compactness of the springs may be reduced, which will reduce the comfort of the mattress. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the claims, specification and the above-mentioned drawings of the present invention, unless otherwise expressly defined, directional words such as the terms "height", "upper end", "top", "bottom", "inside", "outside", "up", "down", "front", "back" and the like indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the specific scope of protection of the present invention.

[0038] Reference Figure 1-12 This embodiment provides an elastic module with a large support area, which includes multiple spring supports 1 and multiple conical springs 2, wherein the spring supports 1 are used to detachably mount the conical springs 2 on the mounting frame of the elastic pad, and the conical springs 2 make the elastic pad full of elasticity.

[0039] The spring support 1 is configured to hold and fix the conical spring 2. The end face ring at one end of the conical spring 2 is larger than the end face ring at the other end, thereby forming a conical structure. The spring support 1 includes a lower base 10 and an upper cover 11. The lower base 10 is circular and the upper cover 11 is rectangular. The large end of the conical spring 2 is arranged on the upper cover 11. The area of ​​the upper cover 11 is larger than that of the lower base 10, forming an inverted conical structure. The conical spring 2 is fixed between the upper cover 11 and the lower base 10.

[0040] When the conical spring 2 is fixed between the upper cover 11 and the lower base 10 of the spring bracket 1, the end face ring of the large end of the conical spring 2 is connected to the upper cover 11 of the spring bracket 1, and the end face ring of the small end is abutted against the lower base 10. In this way, the conical spring 2 is installed in the spring bracket 1, and can fit more firmly with the spring bracket 1 and receive more consistent force.

[0041] More specifically, the upper cover 11 of the spring bracket 1 is provided with a circular opening 110, the size of which is just the same as the size of the end face ring of the conical spring 2. A downwardly bent clip plate 111 is evenly spaced around the circular opening 110 of the upper cover 11 as a spring mounting portion. The clip plate 111 extends toward the center of the circular opening 110 and bends downward so that an arc-shaped clip groove 112 is formed on the back of the clip plate 111. The width of the clip groove 112 is just the same as the width of the spring bracket 1. The thickness of the metal coil wire of the conical spring 2 is consistent, so the connection between the large end face ring of the conical spring 2 and the upper cover 11 can be achieved by clamping the metal coil wire of the large end face ring of the conical spring 2 into the downward bent clamping groove 112 of each clamping plate 111. At this time, the other end of the conical spring 2 fixed in the spring mounting portion is in contact with the lower base 10. The conical spring 2 is deformed between the clamping plate 111 of the upper cover 11 and the lower base 10. The conical spring 2 is installed in the spring bracket 1 with a predetermined initial compression force.

[0042] In order to prevent the conical spring 2 in each spring support 1 from becoming entangled with the conical spring 2 in the adjacent spring support 1 or other components, in this embodiment, the spring support 1 further includes a plurality of flexible straps 13. The plurality of flexible straps 13 are evenly spaced apart and arranged between the corresponding upper cover 11 and the lower base 10. When the conical spring 2 is retained between the lower base 10 and the upper cover 11, the flexible straps 13 are located outside the conical spring 2. Since the flexible straps 13 are located outside the conical spring 2, when adjacent conical springs 2 approach, the flexible straps 13 have a certain blocking effect, preventing the conical springs 2 from becoming entangled with other components. The flexible straps 13 are integrally connected to the upper cover 11 and the lower base 10, and the entire spring support 1 is formed in one piece.

[0043] In this embodiment, the area of ​​the upper cover 11 of the elastic module spring bracket 1 is larger than the area of ​​the lower base 10, thereby forming an inverted cone-shaped spring structure. When the elastic module is installed on the mounting frame of the elastic pad, the lower base 10 of the spring bracket 1 is connected to the mounting frame of the elastic pad. At this time, the upper cover 11 with a larger area of ​​the elastic module serves as the support surface of the human body. Due to the larger area of ​​the upper cover 11, when the elastic module is installed on the mounting frame, the springs are more compact and there is no gap between the support surfaces. When the user uses the elastic pad, the force area is larger, the force of the conical spring 2 will be more dispersed, the risk of deformation of the elastic pad is reduced, and the user will feel more comfortable.

[0044] At the same time, because the elastic module presents an inverted cone shape, it is prone to tipping and skewing when installed on the mounting frame. Therefore, to further enhance the installation security and compactness of the elastic module, in this embodiment, the upper covers 11 of the multiple spring brackets 1 that hold the conical springs 2 are connected to form a row of spring structures. This makes the upper covers 11 of the spring brackets 1 more compact with adjacent upper covers 11, and also prevents the inverted cone-shaped elastic module from tipping and skewing when installed on the mounting frame of the elastic pad, thereby improving the security of the elastic pad.

[0045] In order to maintain the original function of the independent spring elastic pad, avoid mutual interference between two or more people using the elastic pad at the same time, and maintain the original softness of the elastic pad, in this embodiment, the connection between the upper cover 11 of the multiple spring brackets 1 of the elastic module is preferably a flexible connection, and each spring is independent of each other. In this way, when multiple users use the elastic pad at the same time, each spring compresses independently without affecting other springs over a large area. The elastic module can also move up and down independently, so that users will not affect other users when moving or turning over, and it is more comfortable. In this embodiment, the upper covers 11 of the multiple spring brackets 1 of the elastic module are connected to each other using a flexible connecting belt 113.

[0046] Furthermore, the lower base 10 has a module mounting portion for detachably mounting the elastic module to the mounting frame of the elastic pad. Preferably, the module mounting portion is constructed as at least two slides 14 parallel to each other arranged on the bottom surface of the lower base 10 so that the lower base 10 can be slidably assembled to the mounting frame in the elastic pad through the slides 14.

[0047] The slideway 14 is composed of two mutually parallel slide rails 140, each of which includes a first portion 140.1 extending outwardly from the bottom surface of the lower base 10 in a vertical direction and a second portion 140.2 extending horizontally from the end of the first portion 140.1, with the second portions 140.2 of the two slide rails 140 extending inwardly toward each other. The slideway 14 is preferably suitable for use as a T-shaped slide rail on a mounting frame. When the lower base 10 is slidably assembled to the mounting frame in the elastic pad via the slideway 14, the two parallel first portions 140.1 can cooperate with the mounting frame in the horizontal left and right directions, and the two second portions 140.2 extending inwardly toward each other can cooperate with the mounting frame in a vertical direction to allow the elastic module to be detachably mounted on the mounting frame.

[0048] When the elastic module is slidably assembled onto the mounting bracket of the elastic pad via the slideway 14, in addition to the positioning function of the slide rails on the mounting bracket that cooperate with the slideway 14, the lower base 10 also has positioning holes 100 for positioning the elastic module to determine the installation position of each elastic module on the mounting bracket of the elastic pad. The positioning holes 100 can be used to determine whether the elastic module is properly installed on the mounting bracket. At the same time, the positioning holes 100 also serve to interlock with the elastic connectors on the mounting bracket to limit the elastic module along the sliding direction.

[0049] In the application scenario of the detachable elastic pad, there is also the problem of storing and transporting the disassembled parts such as the elastic module and the mounting frame. In order to facilitate the storage of the disassembled elastic module of this embodiment or to freely plan the storage space during transportation, in this embodiment, the adjacent spring brackets 1 of the elastic module can be rotated around the connection 115 of the upper cover 11. Therefore, when the disassembled elastic module needs to be stored, the row of conical springs 2 can be folded and rotated along the length direction to reduce its length, thereby saving storage space.

[0050] In this embodiment, the upper covers 11 of the two middlemost spring supports 1 of the elastic module formed by multiple spring supports 1 are each provided with two connections 114, 115, and the two connections 114, 115 are respectively located at two vertex positions of the upper cover 11, wherein the connection 114 at one vertex position is detachable, and the connection 115 at the other vertex position is hinged so that the spring support 1 can rotate around the hinged connection 115.

[0051] Specifically, the vertex connection 114 of the upper cover 11 of the spring bracket 1 extends outward in the horizontal direction to form a rectangular connecting block 114.1 as a first connecting structure, and a groove 114.2 is provided inside the connecting block 114.1. The vertex connection 114 of the upper cover 11 of the adjacent spring bracket 1 also extends outward in the horizontal direction to form a plug-in plate 114.3 that can be inserted into the groove 114.2 as a second connecting structure, wherein a limiting hole 114.4 is further provided on the side of the connecting block 114.1. The inserting plate 114.3 protrudes outward on one side toward the limiting hole 114.4 to form a locking structure 114.5. The locking structure 114.5 is elastic. When the locking structure 114.5 is inserted into the limiting hole 114.4, it cooperates with the limiting hole 114.4 in a circumferential limiting manner. The inserting plate 114.3 also includes a releasing member 114.6. The releasing member 114.6 pushes the locking structure 114.5 away from the limiting hole 114.4 to release the limiting cooperation between the locking structure 114.5 and the limiting hole 114.4.

[0052] When the conical spring 2 is to be folded, it is only necessary to press the release member 114.6, and the release member 114.6 pushes the elastic locking structure 114.5 away from the limiting hole 114.4, thereby releasing the limiting cooperation between the locking structure 114.5 and the limiting hole 114.4, and then the plug plate 114.3 is pulled out from the groove 114.2 of the connecting block 114.1 to achieve the disassembly of the connection 114, and then the spring bracket 1 is rotated around the hinge connection 115 to rotate and fold the original row of elastic modules along the length direction to shorten the length and save storage space.

[0053] The above description and embodiments are intended to explain the scope of protection of the present invention, but do not constitute a limitation thereto. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
