Abstract
Description
[Technical field]
[0001] The present invention relates to the field of furniture, and in particular to resilient modules and resilient pads for use in furniture. [Background technology]
[0002] Furniture such as beds are an essential part of people's lives. Most of the current large furniture is not easy to disassemble or to restore after disassembly. However, with the development of modern life, in order to meet the needs of population relocation and outdoor leisure, furniture, especially beds, need to be disassembled and assembled more and more frequently. Since it is very difficult to disassemble and assemble beds during transportation and movement, in order to reduce the burden of transportation and movement, beds that are still usable may be discarded.
[0003] A bed usually consists of a bed frame, an elastic pad and a cover, and the current elastic pad is generally a one-piece mattress formed by multiple stacks and springs, which is a one-piece non-removable mattress, which is large in size and difficult to disassemble and store.
[0004] The current independently packaged spring mattress is intended to prevent two or more people sleeping on the bed at the same time from affecting each other (for example, when the weight difference between the individuals is relatively large, when one person turns over or moves, it is impossible to prevent affecting the other person). In this type of mattress, each spring is independently packaged in a bag or sleeve made of nonwoven fabric or other materials. The spring packages are arranged as shown in the drawings, and then the entire foam rubber is covered on the outside of the arranged spring package set by adhesion or bonding, thereby forming a furniture cushion or a necessary spring cushion in the form of a furniture cushion. However, the independently packaged spring mattress is still a whole product, which is not removable and is not easy to transport. Furthermore, in the independently packaged spring mattress, the nonwoven fabrics for covering the packaged springs are adhered and pulled to each other, so when the mattress is pressed, the packaged springs cannot move up and down as if they were completely independent, which affects the comfort of the mattress.
[0005] In addition, current mattresses have the further disadvantage of being difficult to clean. In general, with a normal mattress, it is generally possible to remove only the bed cover, but the sponge part cannot be removed, making cleaning difficult. Even if latex rubber has a certain degree of dust mite prevention effect, one mattress may be used for several years, and the sponge part that is difficult to clean may have a significant impact on hygiene. Summary of the Invention [Problem to be solved by the invention]
[0006] Therefore, there is a need to improve the design of the elastic pad so that it can be more easily removed, moved, reassembled, and stored in a compact space, and also has better clinicability and comfort.
[0007] In response to the problems existing in the prior art, the present invention provides an elastic module and an elastic pad for use in furniture.

[0032] The elastic module and the elastic pad of the present invention will be described in detail below with reference to the drawings. Only the preferred embodiments of the present invention are described here, and those skilled in the art can imagine other forms that can realize the present invention based on the preferred embodiments, and the other forms also fall within the scope of the present invention.
[0033] As shown in FIG. 1A, a preferred embodiment of the elastic module according to the present invention includes a base 20, a spring 10, and an end cap 30, which can be removably assembled together to form the elastic module, in which the base 20 and the end cap 30 are integral parts and may be integrally molded from the same material (e.g., plastic), or may be formed into an integral part from multiple parts by ultrasonic welding or other methods. Specifically, the base 20 is provided with a spring fixing part 21 for removably holding one end of the spring 10, and an end cap locking part 22 for removably fixing the end cap 30. The end cap 30 includes a lid body part 31, a locking part 32, and a flexible connection part 33 for connecting the two together. The lid body part 31 is provided with a spring fixing part 311 on the side facing the base 20 for removably holding the other end of the spring 10. The locking part 32 is configured to be releasably locked with the end cap locking part 22. For example, as shown in FIG. 1B and FIG. 1C, the locking portion 32 may include a base 321 and a snap 322 extending downward from the bottom surface of the base 321. The end cap locking portion 22 may include a protruding base 221 and a locking hole 222 formed in the protruding base 221. When assembling the elastic module, the locking portion 32 and the locking hole 222 are aligned, and then the base 321 of the locking portion 32 is pressed toward the locking hole 222 to elastically deform the snap 322 and penetrate the locking hole 222. After penetrating the locking hole 222, the snap 322 recovers its original shape and is removably fixed in the locking hole 222, thereby fixing the spring 10 between the base 20 and the end cap 30, thereby forming an elastic module. Preferably, the spring 10 in the elastic module has a predetermined initial compression force to form a desired comfortable hardness. The locking holes 222 shown in FIGS. 1B and 1C are rectangular, and correspondingly, the snaps 322 are linear structures, and such an arrangement can prevent the end cap 30 from rotating relative to the base 20 to a certain extent.In other embodiments of the present invention, the locking hole 222 may be of other shapes, for example, circular, and the snap 322 is correspondingly arc-shaped, and such a structure is more convenient for assembly.
[0034] As shown in FIG. 2A, in the assembled elastic module, the flexible connection 33 is located inside the spring 10 along the radial direction of the spring 10, and the lower surface of the base 321 is joined to the upper surface of the protruding base 221, so that the connection between the end cap 30 and the base 20 is more robust and the locking portion 32 and the flexible belt 33a can be prevented from penetrating the locking hole 222. In other embodiments of the present invention, the protruding base 221 may be omitted. When the spring 10 is compressed by the elastic module being subjected to pressure, the flexible connection 33 is adaptively deformed. Preferably, the flexible connection 33 includes a flexible belt 33a. Although two flexible belts 33a are shown in the drawings, those skilled in the art should understand that the flexible connection 33 may include more than one flexible belt 33a, for example, three flexible belts 33a are shown in FIG. 3A, and four flexible belts 33a are shown in FIG. 3B.
[0035] The spring fixing portion 21 on the base 20 may be a slot, a recess, or other form. For example, as shown in Figures 1C and 2A, the spring fixing portion 21 may be in the form of a circumferential wall 211, the dimensions of which are designed to be able to fit closely to the outer side of the lower end of the spring 10 and thereby restrict the lower end of the spring 10 in the radially outward direction. Furthermore, the spring fixing portion 21 may further include a circumferential wall 212, the dimensions of which are designed to be able to fit closely to the lower end of the spring 10 and thereby restrict the lower end of the spring 10 in the radially inward direction.
[0036] The spring fixing portion 311 in the lid body portion 31 may be a slot, a recess, or other form. For example, as shown in FIG. 2D, the spring fixing portion 311 may be a circumferential flange that surrounds the periphery of the lid body portion 31 and fits tightly against the outer tip of the spring 10. Similarly, the spring fixing portion 311 may include a circumferential wall located inward of the tip of the spring.
[0037] 2B and 2D, when the snap 322 is secured within the locking hole 222, the lower base end of the snap 322 can be flush with or recessed upwardly from the bottom surface of the base 20 to maintain a stable position of the base 20.
[0038] As shown in Figures 2C and 2D, a recess or depression 23 is formed on the bottom surface of the base 20, surrounding the base end of the snap 322. The radial dimension of the recess 23 is larger than the dimension of the base end of the snap 322 along the radial direction of the base 20. This forms an operating space surrounding the snap 322, and makes it convenient for fingers or a disassembly tool to be inserted into the recess 23 to release the snap 322.
[0039] 4A to 5B show another preferred embodiment of an elastic module according to the present invention, which is basically similar to the elastic module described above. The elastic module includes a base 60, a spring 10, and an end cap 70, which can be removably assembled together to form the elastic module, in which the base 60 and the end cap 70 are integral members, and may be integrally molded from the same material (e.g., plastic), or may be formed into an integral member from multiple parts by ultrasonic welding or other methods. In this embodiment, the same or similar characteristic configurations are given the same or similar reference numerals, and the description of the same parts as in the above embodiment is omitted. The difference between this embodiment and the above embodiment is the locking portion 72 of the end cap 70 and the end cap locking portion 62 installed on the base 60 for locking the end cap. As shown in the drawings, the locking portion 72 may include a base 721 and a latch member 722 extending downward from the bottom surface of the base 721. The end cap locking portion 62 may include a protruding base 621 and a locking hole 622 formed in the protruding base 621, and the shape of the latch member 722 and the locking hole 622 is designed so that the latch member 722 is locked in or released from the locking hole by rotating relative to the locking hole 622. For example, as shown in FIG. 4B and FIG. 4C, the latch member 722 may be a narrow and slender member extending generally parallel to the base 721, and a neck portion having a small dimension is provided between the base 721. The locking hole 622 may have a shape corresponding to the latch member 722, but the dimension is slightly larger than the dimension of the latch member 722 to facilitate the latch member 722 passing through. When the elastic module is assembled, the direction of the latch member 722 can be adjusted to align with the locking hole 622, and the latch member 722 passes through the locking hole 622 in that direction. The latch member 722 is then rotated (eg, 90 degrees) so that it locks under the base 60 , thereby securing the spring 10 between the base 60 and the end cap 70 .Preferably, the springs 10 in the elastic module are provided with a predetermined initial compression force to provide a desired comfortable firmness.
[0040] 5A and 5B, in the assembled state of the elastic module, the flexible connecting portion 33 is located radially inward of the spring 10, and the lower surface of the base portion 721 is joined to the upper surface of the protruding base 621, which makes the connection between the end cap 70 and the base 60 more robust and prevents the locking portion 72 and the flexible belt 33a from further penetrating the locking hole 622. In other embodiments of the present invention, the protruding base 621 may be omitted.
[0041] 5A and 5B are bottom views, in which Fig. 5A shows that the latch member 722 penetrates the lock hole 622 in a first direction, and Fig. 5B shows that the latch member 722 in Fig. 5A is locked in a second direction after rotating a certain angle (e.g., about 90 degrees). In order to prevent the latch member 722 in the locked state from being accidentally released from the base 60 by rotating, one or more stopper protrusions 63 may be provided near the lower lock hole 622 of the base 60 to hold the latch member 722 in the lock direction (second direction).
[0042] Further referring to FIG. 5B, when the latch member 722 is fixed within the lock hole 622, the lower base end of the latch member 722 can be aligned with the bottom surface of the base 60 or recessed upward, thereby maintaining a stable position of the base 60.
[0043] In order to facilitate twisting of the locking portion 72, a plurality of recesses and / or a plurality of protrusions may be provided around the periphery of the base 721, as shown in FIG. 4B.
[0044] 7A to 7F show an elastic pad according to the present invention, in which a plurality of bases as described above are previously fixed to a base fabric 80 of the elastic pad by adhesive bonding, ultrasonic welding, riveting or similar means. Although the base 20 is shown in the drawings, it may be replaced by a base 60. After purchasing the product, a consumer can simply fix a plurality of springs 10 and a plurality of end caps 30 or 70 to the corresponding bases 20 or 60 of the base fabric 80 in the above manner and assemble the mattress by himself.
[0045] Further referring to Figures 7C and 7D, in order to improve the comfort of the elastic pad and the stability of the elastic module, a sponge layer 90 may be installed on the top of the elastic module, and the side of the sponge layer 90 facing the elastic module is provided with a plurality of recesses 91, each of which can accommodate a tip portion including the lid body portion 31 or 71 of the elastic module.
[0046] As shown in FIG. 7F, the elastic module further includes a cover fabric 100, and a slider fastener is installed around both the cover fabric 100 and the base fabric 80, thereby detachably connecting the cover fabric 100 to the base fabric 80 to form a closed space for housing multiple elastic modules.
[0047] In order to further improve the comfort of the elastic pad, a single or multiple identical or different cushioning layers may additionally be placed between the sponge layer 90 and the cover fabric 100 as required.
[0048] The spring 10 shown in the drawings is a tapered spring, but those skilled in the art should understand that by adjusting the radial dimensions of the base 20 and end cap 30 or the dimensions of the spring fixing portion, the elastic module according to the present invention may include other types of springs, such as pillar-shaped springs.
[0049] The scope of protection of the present invention is limited only by the claims. Under the teaching of the present invention, those skilled in the art can easily imagine alternatives to the structures disclosed in the present invention as feasible alternative embodiments, and combine the embodiments disclosed in the present invention to create new embodiments, which also fall within the scope of the appended claims.
