Description

[Technical Field]

[0001] The present invention relates to the furniture field, and in particular to a resilient module and a resilient cushion for use in furniture. [Background technology]

[0002] Large furniture such as beds are an essential part of people's lives. Most existing large furniture is difficult to disassemble or to restore after disassembly. However, with the development of modern life and to meet the needs of population transition and outdoor play, furniture, especially beds, are required to be disassembled and assembled more frequently. During the transportation process, disassembling and assembling beds is very difficult, so people often throw away beds that are still usable to reduce the burden of transportation.

[0003] A bed usually consists of a bed frame, a resilient cushion, and an outer cover. Existing resilient cushions are usually one-piece, non-removable, one-piece pads formed by multiple stacked layers and springs. The one-piece pads are large in size and difficult to remove and store.

[0004] Existing spring bed pads packaged in individual bags are designed to prevent two or more people sleeping on the same bed at the same time from interfering with each other (for example, if there is a large difference in weight between individuals, one person's tossing or moving around will inevitably affect the other person). In these types of bed pads, each spring is individually packaged in a bag or tube made of nonwoven fabric or other material. The spring bags are arranged in a pattern, and the outside of the arranged set of spring bags is covered with foam rubber by bonding, adhesive, or other means, thereby forming a spring pad required for furniture pads or other types of furniture pads. However, spring bed pads packaged in individual bags are still whole products, cannot be removed, and are difficult to transport. Furthermore, in these spring bed pads, the nonwoven fabric used to encase the packaged springs in the bags sticks and pulls against each other, so when the bed pad is pressed, the springs packaged in multiple bags cannot move up and down completely independently, which affects the comfort of the bed pad.

[0005] Another drawback of existing bed pads is that they are difficult to clean. For ordinary bed pads, only the bed cover is removable, but the sponge part is not removable, making it difficult to clean. Although latex may have a certain degree of dust mite prevention effect, since one bed pad may be used for several years, the sponge part, which is difficult to clean, poses a significant hygiene risk.

[0006] Therefore, there is a need to improve the design of the elastic cushion so that it can be easily removed, moved and reassembled, can be stored in a compact space, is easy to clean and has better comfort. Summary of the Invention [Problem to be solved by the invention]

[0007] In response to the problems of the prior art, the present invention provides an elastic module for use in an elastic cushion for furniture, and an elastic cushion including the elastic module. The elastic module of the present invention has at least the following advantages: it has a simple structure and can be easily assembled with a sponge pad or the like to form an elastic cushion; the elastic cushion thus formed is easy to remove, and the removed elastic module can be compressed or stacked and fitted back in, thereby significantly saving space in storage and transportation; the elastic module has a flexible connecting part located outside the spring, so that the spring in the elastic module is unlikely to wind around the spring in the adjacent elastic module or other components, whether assembled into the elastic cushion or stacked and fitted in; and the elastic module has a base with a larger force-receiving area and greater stability than an independent spring. Therefore, the elastic cushion is more stable when in use; the initial pressure of the springs in the elastic modules can be predetermined according to need so that the elastic modules have the required hardness, and elastic modules of different hardness can be installed at different locations on the elastic cushion according to need; the elastic modules in the elastic cushion can truly achieve compression and release movements independent of each other, so the elastic cushion of the present invention has better comfort than existing spring bed pads packaged in bags; and the sponge portion of the elastic cushion (sponge block and / or sponge pad) is removable, making it easier to clean and more hygienic. The elastic cushion of the present invention can be used in furniture with elastic cushions, such as, but not limited to, bed pads, sofas, soft benches, etc. [Means for solving the problem]

[0025] The elastic module and the elastic cushion of the present invention will now be described in detail with reference to the drawings. Only preferred embodiments of the present invention will be described here, and those skilled in the art may conceive of other embodiments that can realize the present invention based on the preferred embodiments, and such other embodiments are also included in the scope of the present invention.

[0026] 1A to 1F exemplarily illustrate an elastic module 100 according to a first preferred embodiment of the present invention. As shown in the drawings, the elastic module 100 includes a spring support 120 and a cone-shaped spring 110 installed within the spring support 120. The spring support 120 is for removably mounting the elastic module 100 to a foldable mounting frame. The spring support 120 includes a base 121, an end cover 122, and a plurality of flexible bands 123. In one preferred embodiment, the number of flexible bands 123 is four, and they are uniformly distributed around the outer periphery of the spring support 120. Of course, the number of flexible bands 123 may be two, six, or another number. The base 121 includes a spring mounting seat, an opening 1211 at the center of the spring mounting seat, and a spring mounting portion for mounting the cone-shaped spring 110. The base 121 optionally further includes a module mounting portion for removably mounting the elastic module to a mounting frame. The large-diameter end of the cone-shaped spring 110 is fixed to the spring fixing portion, and the small-diameter end of the cone-shaped spring 110 abuts the end cover 122. In various embodiments of the present invention, the spring fixing portion may be a hook-shaped member or a groove. In this embodiment, the spring fixing portion is a plurality of hook-shaped members 1212 uniformly arranged around the inner circumference of the opening 1211. Flexible bands 123 are positioned outside the cone-shaped spring 110, and both ends of each flexible band 123 are fixedly connected to the base 121 and the end cover 122, respectively. The springs 110 may be provided with a predetermined initial pressure so that the elastic module has ideal stiffness after being attached to the spring supporter 120. With the support of the springs, the elastic module 100 has an overall truncated cone shape.

[0027] Preferably, the spring supporter 120 is a one-piece spring supporter that is molded as a single unit, but it may also be an assembly in which multiple members are assembled.

[0028] As described above, the spring supporter 120 is approximately truncated cone-shaped, so that the end cover 122 of the elastic module 100 can enter the interior of the other elastic module through the opening 1211 in the base 121 of the other elastic module to form an engagement, as shown in FIG. 6 .

[0029] In order to form a stronger fit, preferably, the top of the base 121 is provided with a ring-shaped wall extending around the opening 1211, and a screw 124 is installed on the outside of the ring-shaped wall (shown in FIG. 7A). When multiple elastic modules 100 form a fit, the bottom wall of the slide track 1213 of one of the elastic modules 100 can be rotated to screw into between the screw 124 of the other elastic module 100 and the top of the base 121, thereby forming a stronger fit (shown in FIG. 7B). Alternatively or additionally, the outer periphery of the base 121 may be provided with one or more snap engagement portions 125 extending upward and one or more snap engagement recesses 126 located below the snap engagement portions 125 (shown in FIG. 7C), so that when multiple elastic modules 100 form an engagement, the snap engagement portions 125 of the lower elastic modules can engage with the corresponding snap engagement recesses 126 of the upper elastic modules, thereby forming a strong engagement (shown in FIGS. 7D and 7E).

[0030] Preferably, the module mounting portion is two parallel slide tracks 1213 installed at the bottom of the base 121, and the base 121 is slidably mounted on the slide rails of the foldable mounting frame by the slide tracks 1213, and the slide tracks 1213 are hook-shaped portions that can be hooked onto the slide rails of the mounting frame to prevent the elastic module 100 from separating from the mounting frame.

[0031] Preferably, the opening 1211 is a circular opening, and in order not to interfere with the stacking and insertion of multiple elastic modules, an arc section that matches the circular arc of the opening 1211 is formed in the middle of each slide track 1213, as shown in part A in Fig. 1F. Alternatively, each slide track 1211 may be a divided slide track that is cut in the middle.

[0032] 2 and 3A to 3D exemplarily show a mounting frame 400 according to a first preferred embodiment of the present invention. As shown in the drawings, the mounting frame 400 includes two side frames 410 located on both sides of the mounting frame 400, a plurality of center frames 420 located between the two side frames 410, and a plurality of connectors 430 rotatably connecting the side frames 410 and the center frame 420. Because the side frames 410 and the center frame 420 can rotate around the connectors 430, the mounting frame 400 is foldable, and FIGS. 3C and 3D show the mounting frame 400 in a folded state.

[0033] Preferably, the side frames 410, the center frame 420, and the connectors 430 are all made of metal, and more preferably, the side frames 410 and the center frame 420 are made of rebar by bending and welding, and the connectors 430 are made of rolled metal pieces. As shown in Fig. 2, the side frames 410 and the center frame 420 are all closed frames.

[0034] As shown in FIG. 2, the side frame 410 has a vertical extension 411 extending in its length direction and a plurality of horizontal protrusions 412 extending to one side perpendicular to the vertical extension, the center frame 420 has a vertical extension 421 extending in its length direction and a plurality of horizontal protrusions 422 extending to both sides perpendicular to the vertical extension, and the connector 430 rotatably connects the corresponding horizontal protrusions of two adjacent frames, thereby enabling the mounting frame 400 to be foldable.

[0035] As described above, the reinforcing bars at the vertical extensions 411 can slidably couple with the slide tracks 1213 of the base 121, so that the base 121 of the elastic module 100 is configured to be slidably mounted on the mounting frame 400 along the vertical extensions 411, 421 of the mounting frame. That is, the vertical extensions 411, 421 are used as slide rails that couple with the slide tracks 1213 of the base 121. Preferably, the middle portions 413, 423 of the reinforcing bars at the vertical ends of the side frames 410 and the center frame 420 protrude in a direction perpendicular to the plane in which the vertical extensions and the horizontal protrusions are located (the downward direction shown in the figure) so that the slide tracks of the elastic module can easily translate and slide along the vertical extensions 411, 421 after passing through the ends of the frames.

[0036] In one preferred embodiment of the present invention, two types of side frames and two types of center frames of different lengths may be provided to further facilitate folding of the mounting frame. For example, the side frame 410 may include a first side frame 410A that is long and a second side frame 410B that is short. The center frame 420 may include a plurality of first center frames 420A and a plurality of second center frames 420B spaced apart from one another, with the longitudinal length of the first center frame 420A being slightly longer than that of the second center frame 420B. The purpose of providing frame members of different lengths is to ensure that the protrusions 413, 423 at the ends of adjacent frame members do not interfere with each other when folding the frame, thereby enabling smooth folding. Figures 3C and 3D show the folded state of a frame 400 with frame members of different lengths, in which end A of the longer frame member and end B of the shorter frame member are offset from each other and do not interfere with each other.

[0037] 4A to 4D exemplarily show a state in which the elastic module 100 according to the first preferred embodiment of the present invention is mounted on the mounting frame 400 according to the first preferred embodiment of the present invention. As shown in the drawings, the slide track 1213 of the elastic module 100 can be mounted on the vertical extensions 411 and 421 of the frame member by sliding through the recesses formed by the protrusions 413 and 423.

[0038] 5A to 5E exemplarily illustrate an elastic module 200 according to a second preferred embodiment of the present invention and its mounting on a mounting frame 400. As shown in the drawings, the elastic module 200 includes a spring support 220 and a cone-shaped spring 110 installed within the spring support 220. The spring support 220 is for removably mounting the elastic module 200 to the foldable mounting frame 400. The spring support 220 includes a base 221, an end cover 222, and a plurality of flexible bands 223. In one preferred embodiment, the number of flexible bands 223 is four and they are uniformly distributed around the outer periphery of the spring support 220. The base 221 includes a spring mounting seat, an opening 2211 at the center of the spring mounting seat, and a spring mounting portion for mounting the cone-shaped spring 110. The base 221 further includes a module mounting portion for removably mounting the elastic module to the mounting frame. The larger diameter end of the conical spring 110 is fixed to the spring fixing portion, and the smaller diameter end of the conical spring 110 abuts against the end cover 222. In this preferred embodiment, the spring fixing portion is a plurality of hook-shaped members 2212 uniformly arranged around the inner circumference of the opening 2211. Flexible bands 223 are positioned outside the conical spring 110, and both ends of each flexible band 223 are fixedly connected to the base 221 and the end cover 222, respectively. The spring 110 may be provided with a predetermined initial pressure so that the elastic module has ideal stiffness after being attached to the spring support 120. Due to the spring support, the elastic module 200 has an overall truncated cone shape. The difference from the spring support 120 is that the end cover 222 of the spring support 220 has a circular opening 224 at the center, i.e., the end cover 222 is an annular end cover.

[0039] Preferably, the spring supporter 220 is a one-piece spring supporter that is molded as a single unit, but it may also be an assembly in which multiple members are assembled.

[0040] As described above, the spring supporter 220 has a generally frustoconical shape, which allows the end cover 222 of the elastic module 200 to enter the interior of the other elastic module through the opening 2211 of the base 221 of the other elastic module to form a fit. To form a stronger fit, the screw and snap engagement structure provided on the base 121 of the elastic module 100 can be similarly applied to the base 221 of the elastic module 200.

[0041] Preferably, the module mounting portion of the elastic module 200 is two parallel slide tracks 2213 installed at the bottom of the base 121. The slide tracks 2213 are outward-facing slide tracks with opposite opening directions, unlike the inward-facing slide track 1213 with opposite opening directions. The base 221 can be slidably mounted to the vertically extending portions 411, 421 of the frame members, which are the slide rails of the mounting frame 400, by the slide tracks 2213. In this embodiment, as shown in FIG. 5D , each slide track 2213 is a split slide track that is cut in the middle. Similarly to the slide track 1213, the slide track 2213 is a hook-shaped portion that can be hooked onto the slide rails of the mounting frame to prevent the elastic module 200 from separating from the mounting frame.

[0042] 5E to 5G show an example of a flexible connect tab structure applicable to the elastic module 200. This flexible connect tab structure is used to form a connection between multiple elastic modules attached to a mounting frame, thereby making it less likely for a single elastic module to collapse or detach, and making it less likely for the springs of multiple elastic modules to become wrapped around each other. As shown in the drawings, a flexible connect tab 225 may be integrally formed on the outer side of the flexible band 223. When multiple elastic modules 200 are attached to the mounting frame, the flexible connect tab 225 of one of the elastic modules can be detachably connected to the corresponding flexible connect tab 225 of the adjacent elastic module. Preferably, the flexible connect tabs 225 include a neck 2251 and a T-shaped groove 2252, and the dimensions of the neck 2251 and the T-shaped groove 2252 are set so that one flexible connect tab of two adjacent flexible connect tabs 225 can be removably engaged with the T-shaped groove 2252 of the other flexible connect tab by means of the neck 2251. More preferably, the vertical distance of the flexible connect tabs 225 from the end cover 222 is about ⅓ of the overall height of the elastic module 200.

[0043] FIG. 5H exemplarily shows a state in which multiple elastic modules 200 attached to the mounting frame are connected to each other by flexible connect tabs 225.

[0044] As will be appreciated by those skilled in the art, the flexible connect tab structure described above is similarly applicable to the flexible bands of the elastic modules of other preferred embodiments of the present invention, such as elastic module 100 and elastic module 300 described below.

[0045] 8 and 9A to 9D exemplarily show a foldable mounting frame 500 according to a second preferred embodiment of the present invention. As shown in the drawings, the mounting frame 500 includes a plurality of longitudinally extending section members 510 and a plurality of flexible connectors 520 located between and connecting the longitudinally extending section members, with a central portion 522 of the flexible connector member 520 being thin and bendable, forming a flexible hinge thereat. Both the longitudinal section members 510 and the flexible connector member 520 may be made of plastic, and the longitudinal section member 510 may be a plastic member manufactured by extrusion molding. As can be clearly seen in Figures 9A and 9B, two T-shaped grooves 511 with their openings facing downwards are provided in the middle of the vertical section 510, and a T-shaped protruding block 521 that matches the shape of the T-shaped grooves 511 is provided at the top of the flexible connector 520. As shown in Figure 9C, the T-shaped groove 511 slidably receives the T-shaped protruding block 521, thereby allowing multiple vertical sections 510 to be connected by the flexible connector 520.

[0046] Since the middle portion 522 of the flexible connector 520 is thin and bendable, the entire mounting frame 500 is foldable, and FIG. 9D shows the mounting frame 500 in the folded state.

[0047] As shown in Figures 9A and 9B, the vertical profile 510 has a pair of first horizontal protrusions 512 extending horizontally and a pair of second horizontal protrusions 513 located above them, and the distance between the pair of first horizontal protrusions 512 is greater than the distance between the pair of second horizontal protrusions 513.

[0048] 10A to 10D illustrate an elastic module 300 according to a third preferred embodiment of the present invention. As shown in the drawings, similar to the elastic modules 100 and 200, the elastic module 300 includes a spring support 320 and a cone-shaped spring 110 installed within the spring support 320. The spring support 320 is used to removably mount the elastic module 300 to a foldable mounting frame 500. The spring support 320 includes a base 321, an end cover 322, and a plurality of flexible bands 323. In one preferred embodiment, the number of flexible bands 323 is four and they are uniformly distributed around the outer periphery of the spring support 320. The base 321 includes a spring mounting seat, an opening 3211 at the center of the spring mounting seat, and a spring mounting portion for mounting the cone-shaped spring 110. The base 321 further includes a module mounting portion for removably mounting the elastic module to the mounting frame. The large-diameter end of the conical spring 110 is fixed to the spring fixing portion, and the small-diameter end of the conical spring 110 abuts against the end cover 322. In this preferred embodiment, the spring fixing portion is an annular groove 3212 formed around the inner periphery of the opening 3211. Flexible bands 323 are positioned outside the conical spring 110, and both ends of each flexible band 323 are fixedly connected to the base 321 and the end cover 322, respectively. After being attached to the spring supporter 320, the spring 110 may be provided with a predetermined initial pressure so that the elastic module has ideal stiffness. With the support of the spring, the elastic module 300 has an overall truncated cone shape.

[0049] As described above, the spring supporter 320 has a generally frustoconical shape, which allows the end cover 322 of the elastic module 300 to enter the interior of the other elastic module through the opening 3211 of the base 321 of the other elastic module to form a fit. To form a stronger fit, the split screw and snap-fit ​​structure provided on the bases 121 and 221 of the elastic modules 100 and 200 can be similarly applied to the base 321 of the elastic module 300.

[0050] Preferably, the module mounting portion of the elastic module 300 includes two parallel slide tracks 327 installed at the bottom of the base 321, and the base 321 can be slidably mounted to the first horizontal protrusions 512 of the vertical section 510, which are slide rails of the mounting frame 500, via the slide tracks 327. As shown in FIG. 11A , the slide tracks 327 at the bottom of the base 321 can be slidably connected to the first horizontal protrusions 512, thereby allowing the elastic module 300 to be mounted to the mounting frame 500 via the base 321. Alternatively or additionally, as shown in FIG. 11B , the module mounting portion of the elastic module further includes two parallel slide tracks 328 installed at the top of the end cover 322, and the slide tracks 328 can be slidably connected to the second horizontal protrusions 513, which are slide rails of the vertical section 510, thereby allowing the elastic module 300 to be mounted to the mounting frame 500 via the end cover 322.

[0051] Unlike the elastic modules 100 and 200, the spring supporter 320 of the elastic module 300 is a two-piece spring supporter, consisting of a first half 320A shown in FIG. 10C and a second half 320B shown in FIG. 10D, which are removably assembled by, for example, a snap-engagement device consisting of an insert 325 and a receiving seat 326. The first half 320A and the second half 320B each include one or more complete flexible bands 323, a portion of the base 321, and a portion of the end cover 322, and the first half 320A and the second half 320B are both integrally molded. Preferably, the first half 320A and the second half 320B each include two complete flexible bands 323, half of the base 321, and half of the end cover 322.

[0052] 12A to 12D exemplarily illustrate an elastic module 700 according to a fourth preferred embodiment of the present invention. As shown in the drawings, the elastic module 700 includes a spring support 720 and a cone-shaped spring 110 installed within the spring support 720. The spring support 720 is for removably mounting the elastic module 700 to a foldable mounting frame 700. The spring support 720 includes a base 721, an end cover 722, and a plurality of flexible bands 723. In one preferred embodiment, the number of flexible bands 723 is four and they are uniformly distributed around the outer periphery of the spring support 720. The base 721 includes a spring mounting seat, a circular opening 7211 at the center of the spring mounting seat, and a spring mounting portion 7212 for mounting the cone-shaped spring 110. The base 721 further includes a module mounting portion 7213 for removably mounting the elastic module to the mounting frame. The large-diameter end of the conical spring 110 is fixed to the spring fixing portion 7212, and the small-diameter end of the conical spring 110 abuts the end cover 722. In various embodiments of the present invention, the spring fixing portion may be a hook-shaped member or a groove. In this embodiment, the spring fixing portion is a groove 7212 installed around the inner circumference of the circular opening 7211. Flexible bands 723 are located on the outer side of the conical spring 110, and both ends of each flexible band 723 are fixedly connected to the base 721 and the end cover 722, respectively. After being attached to the spring supporter 720, the spring 110 may be provided with a predetermined initial pressure so that the elastic module has ideal stiffness. With the support of the spring, the elastic module 700 has an overall truncated cone shape.

[0053] As described above, the spring supporter 720 is generally frustoconical, allowing the end cover 722 of the elastic module 700 to enter the interior of the other elastic module through the circular opening 7211 in the base 721 of the other elastic module to form an engagement.

[0054] Preferably, spring supporter 720 is a one-piece, integrally molded spring supporter. As shown in FIGS. 12A to 12D , base 721 of spring supporter 720 is formed by joining four sections: first section 721A, second section 721B, third section 721C, and fourth section 721D. Second section 721B and first section 721A are arranged parallel to and opposite each other, third section 721C is arranged adjacent to and perpendicular to first section 721A, and fourth section 721D and third section 721C are arranged parallel to and opposite each other and adjacent to first section 721A and second section 721B. At least one flexible band 723 is fixedly connected to the top surface of each of the four sections, and the four sections are removably butt-connected by a locking device 7216 to form base 721.

[0055] Preferably, the module mounting portion 7213 is two parallel slide tracks 7213 formed on the outside of the third portion 721C and the fourth portion 721D of the base 721, whereby the base 721 can be slidably assembled to the mounting frame 600 (described below) by a sliding fit between the slide tracks 7213 and the slide rails 611 of the mounting frame 600. That is, the elastic module 700 can be assembled to the mounting frame 600 with its narrow end facing downward. In addition, two second slide tracks 7221 parallel to the slide tracks 7213 are further provided on the top surface of the end cover 722, whereby the end cover 722 can be slidably assembled to the mounting frame 600 by a sliding fit between the slide tracks 7221 and the slide rails 621 of the mounting frame 600. That is, the elastic module 700 can be assembled to the mounting frame 600 with its narrow end facing downward.

[0056] Preferably, to make the relative positions of the multiple elastic modules 700 more stable and less likely to come off, flexible connecting bands 7214 are respectively installed on the outside of the third part 721C and the fourth part 721D of the base 721 and on both sides of the end of the sliding track 7213, with holes formed at the ends of the flexible connecting bands 7214, and two protrusions 7222 are respectively formed on the outside of the sliding track 7221 on the top surface of the end cover 722. When the multiple elastic modules 700 are assembled on the mounting frame 600, the multiple elastic modules 700 can be assembled on the mounting frame 600 with the rough ends and the thin ends alternately facing downward, thereby making full use of space. Among them, the flexible connecting band 7214 of one elastic module 700 (narrow end facing downwards) assembled to the mounting frame 600 by the end cover 722 can snap-engage with the protrusion 7222 of the adjacent other elastic module 700 (rough end facing downwards) assembled to the mounting frame 600 by the base 721 through the terminal hole, thereby making the relative positional relationship between the multiple elastic modules 700 more stable.

[0057] More preferably, to further stabilize the relative positioning of the elastic modules 700 assembled in the same orientation and to prevent them from coming off, at least one pillar-shaped pin 7215 (two in the figure) is provided on the outside of the first part 721A of the base 721, and at least one receiving hole 7217 (two in the figure) is provided at a corresponding position on the outside of the second part 721B of the base 721. When multiple elastic modules 700 are assembled in a row on the mounting frame 600, the pillar-shaped pin 7215 of one of the elastic modules 700 can be inserted into the corresponding receiving hole 7217 of the adjacent elastic module 700, thereby facilitating alignment and fastening.

[0058] 13A to 13D exemplarily show a foldable mounting frame 600 according to a third preferred embodiment of the present invention. As shown in the drawings, the mounting frame 600 includes a plurality of first section members 610 extending in the vertical direction and a plurality of second section members 620 extending in the vertical direction. The first section members 610 include a flat main body extending in the vertical direction and first slide rails 611 extending in the vertical direction located on both sides of the flat main body in the horizontal direction. The second section members 620 include a flat main body extending in the vertical direction and second slide rails 621 extending in the vertical direction located at the middle of the top surface of the flat main body. The first section members 610 and the second section members 620 are arranged side by side in the horizontal direction with a gap between them and connected by a plurality of flexible connectors. The mounting frame 600 can be folded by bending the flexible connectors.

[0059] Furthermore, the base 721 of the elastic module 700 can be slidably assembled to the mounting frame 600 by a sliding fit between the slide track 7213 and the slide rail 611, and the end cover 722 of the elastic module 700 can be slidably assembled to the mounting frame 600 by a sliding fit between the slide track 7221 and the slide rail 621. The vertical sections 610, 620 and the flexible connectors can all be made of plastic, and the vertical sections 610, 620 can be plastic members made by extrusion molding. As clearly shown in FIG. 13D , the cross-sectional shape of the slide rail 621 is approximately an inverted trapezoid, and the gap shape between the two slide tracks 7221 matches the cross-sectional shape of the slide rail 621. Therefore, the elastic module 700, assembled with its narrow end facing downward, cannot move in a direction perpendicular to the mounting frame 600. Similarly, the slide rail 611 is a hook-shaped portion, which prevents the elastic module 700 assembled with its rough end facing downward from moving in a direction perpendicular to the mounting frame 600 .

[0060] Although the elastic module described in the above embodiment only includes a single cone-shaped spring, the elastic module according to the present invention may include multiple cone-shaped springs, thereby reducing the number of times the elastic module is assembled and disassembled to and from the elastic cushion.

[0061] 14A to 14E exemplarily show an elastic module 5000 according to a fifth preferred embodiment of the present invention. As shown in the drawings, the elastic module 5000 includes a spring support 5220 and a row of three cone-shaped springs 110 installed within the spring support 5220. The spring support 5220 is used to removably mount the elastic module 5000 to a mounting frame of an elastic cushion. The spring support 5220 includes a common base 5221, a plurality of end covers 5222, and a plurality of flexible bands 5223, each of which has both ends fixedly connected to the base 5221 and a corresponding end cover 5222. In one preferred embodiment, four flexible bands 5223 are connected to each end cover 5222, and the four flexible bands are uniformly distributed around the outer periphery of the corresponding cone-shaped spring 110. The base 5221 has three spring mounting seats, each having a spring mounting portion 52212 for mounting a conical spring 110. The base 5221 further has a module mounting portion 52213 for removably mounting the elastic module to a mounting frame. Each end cover 5222 and the multiple flexible bands 5223 connected thereto have an overall truncated cone shape, the internal shape of which matches the shape of the conical springs 110. Each end cover 5222 forms a small-diameter end of the truncated cone, and the corresponding spring mounting seats of the base 5221 form multiple large-diameter ends of the truncated cone. The base 5221 has one opening 52211 at the center of each large-diameter end, so that the multiple end covers 5222 and most or all of the flexible bands 5223 of the other elastic module 5000 can enter the interior of the elastic module 5000 through the corresponding opening 52211 to form a fit. The large diameter end of the conical spring 110 is fixed to the spring fixing portion 52212 of the corresponding spring mounting seat, and the small diameter end of the conical spring 110 abuts against the end cover 5222.In this preferred embodiment, the spring fixing portion 52212 is a plurality of hook-shaped members 52212 uniformly distributed around the inner circumference of the opening 52211. Flexible bands 5223 are located on the outer side of the conical spring 110, and both ends of each flexible band 5223 are fixedly connected to the base 5221 and the corresponding end cover 5222, respectively. The spring 110 may have a predetermined initial pressure so that the elastic module has ideal stiffness after being attached to the spring supporter 5220. A circular opening 5224 may be formed in the center of the end cover 5222 of the spring supporter 5220, i.e., the end cover 5222 may be an annular end cover.

[0062] Preferably, the spring supporter 5220 is a one-piece molded integral spring supporter.

[0063] As described above, the spring supporter 5220 has a shape that is approximately conical in cross section, so that the end cover 5222 of the elastic module 5000 can enter the interior of the other elastic module through the opening 52211 in the base 5221 of the other elastic module to form an engagement, as shown in FIG. 15 .

[0064] Preferably, the module mounting portion of the elastic module 5000 is one or more pairs of parallel slide tracks 52213 installed on the bottom of the base 5221. In the embodiment shown in FIGS. 14A to 14E, the opening directions of the pair of slide tracks 52213 are opposite to each other. In an alternative embodiment, the opening directions of the pairs of slide tracks 52213 may face each other. The base 5221 can be slidably mounted to the mounting frame of the elastic cushion by the slide tracks 52213. As shown in FIG. 14C, each slide track 52213 is a split slide track cut in the middle, and the number of the cone-shaped springs 110 and the openings 52211 in the extension direction of the slide track 52213 corresponds to the number of the cone-shaped springs 110 and the openings 52211. In this embodiment, each slide track 52213 has four sections 52213A, 52213B, 52213C, and 52213D. The purpose of dividing the section is to prevent the slide track 52213 from interfering with the opening 52211 and to reduce the size of the base 5221. The slide track 52213 is a hook-shaped portion, and by hooking onto the slide rail of the mounting frame, it is possible to prevent the elastic module 5000 from separating from the mounting frame.

[0065] FIG. 16 exemplarily shows how an elastic module 5000 including a plurality of cone-shaped springs 110 is attached to the mounting frame of an elastic cushion.

[0066] 17A to 17E exemplarily illustrate an elastic module 6000 according to a sixth preferred embodiment of the present invention. As shown in the drawings, the elastic module 6000 includes a spring support 6220 and four cone-shaped springs 110 arranged in a matrix within the spring support 6220.

The base 5221 has four spring mounting seats, each having a spring mounting portion 62212 for mounting a conical spring 110. The base 6221 further has a module mounting portion 62213 for removably mounting the elastic module to a mounting frame. Each end cover 6222 and the multiple flexible bands 6223 connected thereto have an overall truncated cone shape, the internal shape of which matches the shape of the conical springs 110. Each end cover 6222 forms a small-diameter end of the truncated cone, and the corresponding spring mounting seats of the base 6221 form multiple large-diameter ends of the truncated cone. The base 6221 has one opening 62211 at the center of each large-diameter end, so that the multiple end covers 6222 and most or all of the flexible bands 6223 of the other elastic module 6000 can enter the interior of the elastic module 6000 through the corresponding opening 62211 to form a fit. The large diameter end of the cone-shaped spring 110 is fixed to the spring fixing portion 62212 , and the small diameter end of the cone-shaped spring 110 abuts against the end cover 6222 .In this preferred embodiment, the spring fixing portion 62212 is a plurality of hook-shaped members 62212 uniformly distributed around the inner circumference of the opening 62211. Flexible bands 6223 are located outside the cone-shaped spring 110, and both ends of each flexible band 6223 are fixedly connected to the base 6221 and the corresponding end cover 6222, respectively. The spring 110 may be provided with a predetermined initial pressure so that the elastic module has ideal stiffness after being attached to the spring supporter 6220. A circular opening 6224 may be provided at the center of the end cover 6222 of the spring supporter 6220, i.e., the end cover 6222 may be annular.

[0067] Preferably, the spring supporter 6220 is a one-piece molded integral spring supporter.

[0068] As described above, the spring supporter 6220 has an approximately truncated cone shape, which allows the end cover 6222 of the elastic module 6000 to enter the interior of the other elastic module through the opening 62211 in the base 6221 of the other elastic module to form an engagement, as shown in FIG. 18.

[0069] Preferably, the module mounting portion of the elastic module 6000 is one or more pairs of parallel slide tracks 62213 installed on the bottom of the base 6221. In the embodiment shown in Figures 17A to 17E, the opening directions of the two pairs of slide tracks 62213 are opposite to each other, but in an alternative embodiment, the opening directions of each pair of slide tracks 62213 may face each other. The base 6221 can be slidably mounted to the mounting frame of the elastic cushion by the slide tracks 62213. 17C , each slide track 62213 is a split slide track that is cut in the middle, and corresponds to the number of cone-shaped springs 110 and openings 62211 in the extending direction of the slide track 62213. In this embodiment, each slide track 62213 has three sections 62213A, 62213B, and 62213C. The purpose of dividing the sections is to prevent the slide track 62213 from interfering with the openings 62211 and to reduce the size of the base 6221. The slide track 62213 is a hook-shaped portion that can be hooked onto the slide rail of the mounting frame to prevent the elastic module 6000 from separating from the mounting frame.

[0070] FIG. 19 exemplarily shows how an elastic module 6000 including a plurality of cone-shaped springs 110 is attached to the mounting frame of an elastic cushion.

[0071] As can be seen from the above-exemplified embodiments, the elastic module according to the present invention may include any number of cone-shaped springs, and the cone-shaped springs may be distributed in any pattern in the elastic module.

[0072] According to one preferred embodiment of the present invention, the elastic cushion 1000 may include an integral fastening net to better hold the elastic modules in place in the elastic cushion. Figures 21A and 21B show an integral fastening net 1300 according to a first preferred embodiment of the present invention, which includes a plurality of annular portions 1310, each of which is configured to allow a portion of a corresponding elastic module in the elastic cushion to pass through. Preferably, when the integral fastening net 1300 is installed on the elastic module, the vertical distance of the annular portions 1310 from the end cover of the elastic module is approximately 1 / 3 of the overall height of the elastic module.

[0073] 22A to 22D show a second preferred embodiment of the integrated fastening net 1400 of the present invention. As shown in the drawings, the integrated fastening net 1400 is flexible and has a number of hooks 1420 on its edge, which can be hooked onto the mounting frame 400 when the integrated fastening net 1400 is installed on the elastic module.

[0074] More preferably, the top of the sponge cover 1100 is provided with a plurality of bird's nest-shaped structures 1110, and as shown in Figures 23A and 23B, the positions of the plurality of bird's nest-shaped structures 1110 correspond to the positions of the end covers of each elastic module in the foldable mounting frame of the elastic cushion, so that the top of each elastic module is housed in the corresponding bird's nest-shaped structure, thereby restricting the lateral movement of the elastic module and preventing the elastic module from detaching or winding around adjacent springs.

[0075] As shown in Figures 24A and 24B, the elastic cushion 1000 of the present invention may further include a plurality of filled sponge strips 900, which are placed on the integrated fastening net 2300 and are designed to fill the gaps between the elastic modules of the elastic cushion and between the truncated cones of each elastic module, thereby preventing the elastic modules from shaking and detaching and improving the comfort of the elastic cushion. As shown in Figure 24C, similar to the integrated fastening nets 1300 and 1400, the integrated fastening net 2300 includes a plurality of annular portions 2310, each of which is configured to allow a portion of a corresponding elastic module of the elastic cushion to pass through. Preferably, when the integrated fastening net 2300 is attached to the elastic module, the vertical distance of the annular portion 2310 from the end cover of the elastic module is approximately one-third of the overall height of the elastic module.

[0076] As shown in Figures 25C and 25D, the elastic cushion 1000 of the present invention may include an integrated fastening net 3300, which, in addition to a circular portion 3310 for restricting the elastic module, further includes a plurality of small circular portions 3320, each of which is located between the circular portions 3310, and the plurality of circular portions 3310 and the plurality of small circular portions 3320 are arranged at intervals from each other in an array-like form so that when the integrated fastening net 3300 is installed on the elastic module, the plurality of small circular portions 3320 are located just above the gaps between the elastic modules and between the truncated cones of each elastic module.

[0077] Similarly, when the fastening net 3300 is installed on the elastic module, the vertical distance of the annular portion 3310 from the end cover of the elastic module is about 1 / 3 of the overall height of the elastic module.

[0078] 25A and 25B, the elastic cushion 1000 of the present invention may further include a plurality of gap-filling elastic modules 800, each of which has a generally frustoconical shape and can fill the gaps between the elastic modules and between the frustoconical shapes of the elastic modules with its narrow end facing downward, thereby preventing the elastic modules from shaking or detaching and improving the comfort of the elastic cushion. The small-diameter end of the gap-filling elastic module 800 can be fixed to the small annular portion 3320 to fill the gaps.

[0079] 25E illustrates a gap-filling elastic module 800 for filling gaps according to a preferred embodiment of the present invention. As shown in the drawing, the gap-filling elastic module 800 includes a spring support 820 and a small cone-shaped spring 810 installed in the spring support 820. The spring support 820 enables the gap-filling elastic module 800 to be removably assembled to the integrated fastening net 3300. The spring support 820 includes a base 821, an end cover 822, and a plurality of flexible bands 823. In a preferred embodiment, the number of flexible bands 823 is four, and they are uniformly distributed around the outer periphery of the spring support 820. The base 821 has a circular opening at its center, and the large-diameter end of the small cone-shaped spring 810 is fastened to a spring fastening portion of the base 821. The spring fastening portion may be an annular groove formed around the inner periphery of the circular opening of the base 821. The small diameter end of the small cone-shaped spring 810 abuts against the end cover 822. Flexible bands 823 are positioned outside the small cone-shaped spring 810, and both ends of each flexible band 823 are fixedly connected to the base 821 and the end cover 822, respectively. The springs 810 may be provided with a predetermined initial pressure so that the elastic module 800 has ideal stiffness after being attached to the spring supporter 820. With the support of the springs, the gap-filling elastic module 800 has an overall truncated cone shape.

[0080] Preferably, the spring supporter 820 is a one-piece spring supporter that is molded as a single unit, but it may also be an assembly in which multiple members are assembled.

[0081] As described above, the spring supporter 820 is approximately truncated cone-shaped, which allows the end cover 822 of the gap-filling elastic module 800 to enter the interior of the other gap-filling elastic module through the circular opening in the base 821 of the other gap-filling elastic module to form an engagement.

[0082] Furthermore, to enable end cover 822 of gap-filling elastic module 800 to be more stably fastened to small annular portion 3320 of integrated fastening mesh 3300, a plurality of hooks 8221 extending toward the small diameter end of small cone-shaped spring 810 may be formed on the outer periphery of end cover 822, and the small diameter end of gap-filling elastic module 800 may be fastened to small annular portion 3320 by hooks 8221 to fill the gap. Preferably, the plurality of hooks 8221 and the plurality of flexible bands 823 are arranged at intervals along the outer periphery of gap-filling elastic module 800. Alternatively, hooks 8221 may be annular hooks extending 360 degrees along the entire outer periphery of end cover 822.

[0083] The present invention further provides an elastic cushion, and as shown in Figures 20A to 20C, an elastic cushion 1000 according to one preferred embodiment of the present invention may include a mounting frame 400, 500, 600 as described in the above embodiments and a plurality of elastic modules 100, 200, 300, 700, 5000, 6000, etc. attached to the mounting frame. The elastic cushion 1000 may further include a sponge cover 1100 covering the plurality of elastic modules attached to the mounting frame, and a cloth cover 1200 covering the sponge cover.

[0084] Each type of resilient module according to each embodiment of the present invention may include other functional components / assemblies, which will now be described in more detail.

[0085] Figures 26A and 26B show an elastic module with restricting holes according to a preferred embodiment of the present invention, wherein the end cover has a substantially planar main body portion, and four restricting holes 224a may be provided in the main body portion, uniformly distributed around the center of the end cover, and the restricting holes are configured to receive a restricting device (Figure 27A) to restrict the relative positions of four adjacent elastic modules. Figures 27A to 27C show an exemplary restricting device 10 for restricting an elastic module, which includes a rectangular main body frame and four tubular portions 11 located at the four corners of the rectangular main body frame, and as shown in the drawings, the rectangular main body frame has reinforcing bars 12 extending along its diagonals. Each tubular portion 11 extends from the rectangular main body frame toward the same side in a direction perpendicular to the rectangular main body frame. The dimensions of the main body frame and the tubular portions are designed so that each tubular portion 11 can be inserted into the corresponding restricting hole 224a in the end cover of the four adjacent elastic modules. Each tubular portion 11 has a tapered end to guide the tubular portion 11 into the restricting hole 224a. As shown in FIG. 27C, an engaging portion 13 is provided on the outer surface of the tubular portion 11, and the engaging portion 13 is configured to engage with the restricting hole 224a. As shown in FIG. 27B, the tubular portion 11 has a central hole 14, in which a recess 15 for receiving the engaging portion 13 is formed. As shown in FIG. 27D, multiple limiters 10 can be fitted together, and the dimensions of the central hole 14 are designed to receive the tapered end of the tubular portion 11 of another limiter 10.

[0086] FIG. 27E exemplarily illustrates a state in which a plurality of elastic modules shown in FIG. 26A are fixed by the restriction tool 10 shown in FIG. 27A.

[0087] 28A to 28C show an elastic module equipped with a pivotal fastening device according to a preferred embodiment of the present invention. The pivotal fastening device includes a pair of protrusions 21 and a pair of arc-shaped openings 22 mounted on an end cover of the elastic module. The pair of protrusions 21 and the pair of arc-shaped openings 22 are mounted on the end cover in a centrally symmetrical manner along the circumferential direction, and the protrusions 21 and the arc-shaped openings 22 are alternately arranged along the circumferential direction of the end cover. Each protrusion 21 includes a narrow base 211a and a thick end 212a, the base 211a being essentially cylindrical, and the end 212a being essentially frustoconical. Each arc-shaped opening 22 includes a narrow arc-shaped extension 221a and a wide end opening 222a located at one end of the arc-shaped opening 22. That is, the radial dimension of the end opening 222a is larger than the radial dimension of the arc-shaped extension 221a. The radial (width) dimension of the end opening portion 222a is designed to allow the thick end 212a of the protrusion 21 to pass through, while the radial (width) dimension of the arc-shaped extension portion 221a is designed not to allow the thick end 212a to pass through. As a result, when the end covers of two elastic modules are facing each other, the pair of protrusions 21 of one end cover can pass through the pair of end opening portions 222a of the other end cover, and the pair of protrusions 21 of the other end cover can pass through the pair of end opening portions 222a of the one end cover. As shown in Figures 28D and 28E, when the two elastic modules are screwed together in the locking direction, the base 211a of each protrusion 21 moves along the corresponding arc-shaped opening 22 to its arc-shaped extension portion 221a, and the thick end 212a of each protrusion engages with the narrow arc-shaped extension portion 221a, thereby fixing the two elastic modules in a form in which the end covers face each other.

[0088] FIG. 28F is a partially enlarged view of FIG. 28E, showing an interlock device as an option installed on the end cover. The interlock device includes a pair of arc-shaped walls 23 and a pair of columns 24 installed on the end cover along the circumferential direction of the end cover in a centrosymmetric form. The arc-shaped walls 23 and the columns 24 are alternately arranged with each other along the circumferential direction of the end cover. Corresponding to the interlock device, the dimension of the base 211a of the protrusion 21 of the swivel fixing device along the height direction of the elastic module is set such that when the two elastic modules are fixed in a form where the end covers face each other, they are allowed to move a predetermined distance along the height direction of the elastic module relative to each other. This distance is designed to be larger than the dimension of the column 24 along the height direction of the elastic module. Thus, when the two elastic modules are screwed in the locking direction, the arc-shaped wall 23 of one of the elastic modules is allowed to straddle over the column 24 of the other elastic module. As shown in FIG. 28F, when the two elastic modules are locked in a form where the end covers face each other, the column 24 of one of the elastic modules is joined to one end of the arc-shaped wall 23 of the other elastic module, preventing the two elastic modules from rotating relative to each other in the unlocking direction opposite to the locking direction. When removal is necessary, after manually moving the two elastic modules away from each other so that the joining of the arc-shaped wall 23 and the column 24 is released, the two elastic modules may be rotated in the unlocking direction. Preferably, the interlock devices 23, 24 are located outside the radial direction of the swivel fixing devices 21, 22.

[0089] 29A and 29B show an elastic module having shape-matching locking structures 31, 32 according to a preferred embodiment of the present invention. The locking structures 31, 32 are located on the four sides of the base of the elastic module and include protrusions 31 extending outward perpendicular to the corresponding side along the horizontal direction of the base and recesses 32 extending inward perpendicular to the corresponding side along the horizontal direction of the base. The protrusions 31 and recesses 32 are alternately arranged on the sides of the base, and the shape of the protrusions 31 matches the shape of the recesses 32, allowing the protrusions 31 and recesses 32 of one elastic module to be inserted into and received by the corresponding recesses 32 and protrusions 31 of the adjacent elastic module, respectively, in a direction perpendicular to the plane of the base, thereby restricting relative movement between the adjacent elastic modules in the horizontal direction. The protrusions 31 include a neck and a head located at the end of the neck and wider than the neck. The recess 32 has an opening and a recess located inside the opening and enlarged wider than the opening, and the shapes of the opening and the enlarged recess respectively fit the neck and head of the protrusion, thereby allowing the protrusion 31 and the recess 32 of one elastic module to be inserted and received into the corresponding recess and protrusion of the other elastic module arranged adjacently, respectively, along a direction perpendicular to the surface on which the base is located.

[0090] Preferably, each protrusion 31 further includes a slider 311a and an elastic member 312a. The slider 311a is configured to be able to slide outward and inward along the horizontal direction of the base of the protrusion 31, perpendicular to the corresponding side edge, and an outwardly protruding tongue-shaped portion 3111a is provided on the outer side of the slider 311a. One end of the elastic member 312a is fixed to the base, and the other end of the elastic member 312a is a free end. The elastic member 312a passes through the slider 311a, and the slider 311a is fixed to a position between the fixed end and the free end of the elastic member 312a, so that the elastic member 312a exerts an elastic force that causes the slider 311a to slide outward relative to the slider. The base is provided with two position limiting members 313a and 314a for limiting the range of motion of the free end of the elastic member 312a. The first position limiting member 313a limits the free end of the elastic member 312a to a first position so that the slider is in the retracted position, and the second position limiting member 314a limits the free end of the elastic member 312a to a second position so that the slider is in the extended position. Each recess 32 is provided with a groove 322a for accommodating the tongue 3111a of the slider in the extended position, thereby limiting the relative movement along the height (vertical) direction between adjacent elastic modules. Preferably, the edges of each recess 32 located on the upper and lower surfaces of the base are provided with guide slopes 321a for guiding the tongue 3111a to enter the recess 32. Figure 29C shows an example of how multiple elastic modules are locked together by the interlocking device shown in Figures 29A and 29B. As can be seen from the drawing, the protrusion 31 of each elastic module is aligned with the recess 32 of the adjacent elastic module, and the slider 311a is in the extended position, whereby the tongue 3111a is inserted into the groove 322a.

[0091] 30A and 30B show an elastic module having shape-matching locking structures 41 and 42 according to another preferred embodiment of the present invention, in which the protrusions 41 and the recesses 42 are alternately arranged on the four sides of the base. As shown in the drawings, the elastic module includes locking structures installed on the four sides of the base, each including a protrusion 41 extending outward perpendicular to the corresponding side along the horizontal direction of the base, and a recess 42 extending inward perpendicular to the corresponding side along the horizontal direction of the base. The shape of the protrusion 41 matches or complements the shape of the recess 42, so that the protrusion 41 of one elastic module can be inserted into the recess 42 of the other elastic module along the horizontal direction. Preferably, the protrusions 41 and the recess 42 are approximately triangular. More preferably, protruding bases 411a are provided on the upper and / or lower surfaces of the protruding portion 41, and through holes 421a are provided on the upper and / or lower walls of the recessed portion 42, so that the protruding bases 411a can enter and leave the through holes 421a in the recessed portion of the other elastic module. Figure 30C exemplarily shows a state when multiple elastic modules are combined using the locking structures shown in Figures 30A and 30B, and since the locking structures on each side of the base of the elastic module are the same, they can be joined arbitrarily.

[0092] FIG. 30D illustrates an elastic module with shape-matching locking structures according to another preferred embodiment of the present invention. As shown in the drawing, the elastic module includes locking structures installed on the four sides of a base. The locking structures include protrusions 43 extending outward perpendicular to the corresponding side edges along the horizontal direction of the base and recesses 44 extending inward perpendicular to the corresponding side edges along the horizontal direction of the base. As shown in the drawing, the protrusions 43 and the recesses 44 are arranged to face each other on the four sides of the base. For example, a pair of protrusions 43 is provided on one side of the base, and a pair of recesses 44 is provided on the other side opposite the protrusions 43. The shape of the protrusions 43 matches or complements the shape of the recesses 44, allowing the protrusions 43 of one elastic module to be inserted into the recesses 44 of another elastic module along the horizontal direction. Preferably, the protrusions 43 and the recesses 44 are approximately triangular. More preferably, protruding bases 431a are provided on the upper and / or lower surfaces of protruding portion 43, and through holes 441a are provided on the upper and / or lower walls of recessed portion 44, so that said protruding bases 431a can enter and leave said through holes 441a in the recessed portion of the other elastic module. Figures 30E and 30F exemplarily show two types of states when multiple elastic modules are combined using the locking structure shown in Figures 30C and 30D.

[0093] 31A and 31B show an elastic module having a T-shaped (or wedge-shaped) connector according to a preferred embodiment of the present invention. As shown in the drawings, a T-shaped (or wedge-shaped) connector 51 is provided on one or more sides of the base of the elastic module, extending along the corresponding side. The T-shaped connector 51 includes a first flange 511a extending upward along the height direction of the elastic module and a second flange 511b extending downward along the height direction of the elastic module. When the two T-shaped connectors 51 of two elastic modules are arranged adjacent to each other, the two T-shaped connectors 51 can be connected by a connector 52 (see FIGS. 31C and 31F) including a pair of upper flanges 521a extending downward and a pair of lower flanges 521b extending upward. The connector 52 slides along the first flange 511a and the second flange 511b, passing between the two elastic modules arranged in parallel to connect them. 31C , the connector 52 includes an intermediate wall and a pair of downwardly extending upper flanges 521a and an upwardly extending pair of lower flanges 521b, each located on either side of the intermediate wall. The intermediate wall can be passed between two adjacently arranged connecting portions 51 of two adjacently arranged elastic modules, thereby connecting the two adjacently arranged elastic modules via the upper flanges 521a and the lower flanges 521b. The upper flanges 521a and the lower flanges 521b, which are located on the same side of the dividing wall of the connector 52, form a sliding track, and the first flange 511a and the second flange 511b of the elastic module can slide along the sliding track. Preferably, the sliding track may be wedge-shaped, and the first flange 511a and the second flange 511b may be formed in a wedge shape that matches the wedge shape of the sliding track. FIG. 31D exemplarily shows a state in which elastic modules having T-shaped connectors 51 shown in FIGS. 31A and 31B are connected to form a row by the U-shaped connector shown in FIG. 31C.

Any number of elastic modules may be joined in any form according to actual needs (e.g., the size of the elastic cushion).

[0096] Figures 31L and 31M show examples of elastic cushions of different sizes that are joined using the elastic modules and U-shaped connectors shown in Figures 31E to 31H, and all four sides of the base of the elastic module in this embodiment are provided with T-shaped (or wedge-shaped) connectors 51, so that horizontally adjacent elastic modules and vertically adjacent elastic modules are all connected by U-shaped connectors 52.

[0097] 31I and 31J show an elastic module having wedge-shaped (or T-shaped) joints 53, 54 according to a preferred embodiment of the present invention. As shown in the drawings, a wedge-shaped (or T-shaped) groove 54 is provided on one side of the base, a wedge-shaped (or T-shaped) protrusion 55 that can be linked to the shape of the wedge-shaped (or T-shaped) groove 54 is provided on the side opposite to that side, and wedge-shaped (or T-shaped) connectors 53 are provided on the remaining two opposite sides, and the wedge-shaped protrusion 55 can slide into the wedge-shaped groove 54 of the base of the other elastic module to connect the two elastic modules, and the wedge-shaped protrusion 53 of one elastic module and the wedge-shaped protrusion 53 of the other elastic module can be connected by a U-shaped connector 52 shown in FIG. 31F. Preferably, the two side walls 541a, 541b forming the wedge-shaped groove 54 are cut off, and the side walls 541a, 541b are offset from each other. Figure 31K shows an enlarged cross-sectional view of the two elastic modules shown in Figures 31I and 31J joined together by the wedge-shaped protrusion 55 and the wedge-shaped groove 54.

[0098] Figures 31N and 31P show examples of elastic cushions of different sizes that are joined using the elastic modules shown in Figures 31I to 31K and the U-shaped connectors shown in Figure 31F. As shown in the drawings, a pair of opposing side edges of the base of the elastic module in this embodiment are each provided with a wedge-shaped groove 54 and a wedge-shaped protrusion 55 that can be linked to each other, and the other pair of opposing side edges are each provided with a T-shaped (or wedge-shaped) connecting portion 53, so that adjacent elastic modules in the horizontal direction (horizontal direction in the figures) are connected by U-shaped connectors 52, and adjacent elastic modules in the vertical direction (vertical direction in the figures) are connected by their own wedge-shaped grooves 54 and wedge-shaped protrusions 55.

[0099] FIG. 32A shows an elastic module in which a base and an end cover are engaged to compress a spring therebetween, according to one preferred embodiment of the present invention. When the base and the end cover are engaged, the volume of the elastic module is significantly reduced, making it easy to store and transport. FIGS. 32B to 32D show, respectively, perspective, plan, and side views of the base of the elastic module shown in FIG. 32A , and FIGS. 32E and 32F show, respectively, perspective and plan views of the end cover of the elastic module shown in FIG. 32A . As shown in the drawings, the elastic module includes a spring 110e and a spring supporter 120a that can hold and secure the spring. The spring supporter 120a includes a base 121a, an end cover 122a, and a flexible connecting band 123a. The base 121a includes a spring mounting seat, which has a first spring fixing portion 1212a, to which each first spring fixing portion 1212a can fix a first end of a spring 110e. The end cover 122a includes a spring mounting seat, which has a second spring fixing portion 1222a, to which each second end of a spring can be fixed. Both ends of a flexible connecting band 123a are fixedly connected to the base 121a and the end cover 122a, respectively, and are located outside each spring 110e. A screw locking assembly is installed on the base 121a and the end cover 122a, and the base and the end cover are configured to be releasably locked by the screw locking assembly so that the spring can be compressed therebetween. 32B-32F, the threaded lock assembly includes one or more locking posts 127a located on an outer region of base 121a and one or more arcuate openings 128a located on corresponding outer regions of end cover 122a. Each locking post 127a includes a base 1271a and an end 1272a having a cross-sectional dimension larger than that of the base. Each arcuate opening 128a includes an arcuate extension 1281a and an end opening 1282a located at one end of the arcuate opening and having a dimension larger than that of the arcuate extension.The dimensions of the end opening portion 1282a of each arc-shaped opening 128a are designed to allow the thick end 1272a of the corresponding locking post 127a to pass through, and the dimensions of the narrow arc-shaped extension portion of each arc-shaped opening 128a are designed not to allow the thick end 1272a of the corresponding locking post 127a to pass through, so that when the spring is compressed and the thick end of each locking post 127a passes through the corresponding end opening 1282a, by threading the base 121a and the end cover 122a together in the locking direction, the base 1271a of each locking post 127a moves along the corresponding arc-shaped opening 128a to its arc-shaped extension portion 1281a and is engaged with the arc-shaped extension portion 1281a by the end 1272a, thereby releasably locking the base and the end cover. Figures 32G and 32H are exemplary perspective and plan views, respectively, of the resilient module shown in Figure 32A when the base and end cover are engaged. Figure 32I is an exemplary view of a stack of multiple resilient modules in the compressed configuration shown in Figures 32G and 32H. Resilient modules compressed and locked in this manner can significantly reduce storage and transportation space.

[0100] Figures 32J and 32K respectively show exemplary elastic modules that can be engaged with a base and an end cover according to other preferred embodiments of the present invention, in which the flexible connection part of the elastic module shown in Figure 32J is a flexible string 123b, and the flexible connection part of the elastic module shown in Figure 32K is an integrated flexible cover 123c that surrounds the spring 360 degrees.

Preferably, the module mounting portion 1213a is a slide track or slide rail, and the base of the elastic module is slidably assembled to a mounting frame of the elastic cushion. More preferably, the spring supports 120a, 120b, and 120c may be integrally molded. More preferably, the springs are mounted in the spring supports with a predetermined initial compression force. Optionally, an opening 1211a may be provided in the center of the base, and an opening 1221a may be provided in the center of the end cover.

The base 121d includes a pair of first engagement mechanisms 1211d located around its periphery, and the end cover 122d includes a pair of second engagement mechanisms 1221d located around its periphery. The spring packages are removably secured between the base 121d and the end cover 122d, and each spring package includes a spring 110f and a flexible cover 123d that encases the spring. The base 121d and the end cover 122d are releasably engageable with each other via the first engagement mechanisms 1211d and the second engagement mechanisms 1221d, thereby compressing the spring package between the base and the end cover. Preferably, the spring is packaged within the flexible cover 123d with a predetermined initial compression force. While the springs shown in the figures are convex springs with a convex center, those skilled in the art will recognize that they may also be cylindrical springs or concave springs with a concave center. The engagement mechanisms 1211d and 1221d will now be described in detail with reference to Figures 33E to 33G. As shown in the drawings, the pair of first engagement mechanisms 1211d extend radially outward from the base 121d, and each first engagement mechanism includes a first protrusion 12112d, which is located between the first engagement mechanism 1211d and the base 121d. The pair of second engagement mechanisms 1221d extend radially outward from the end cover 122d, and each second engagement mechanism includes a resilient tongue 12211d that can move toward or away from the end cover 122d, and a second protrusion 12212d located outside the tongue. The second protrusion 12212d can be mated to the first protrusion 12112d to engage the base and the end cover, and the second protrusion 12212d disengages from the first protrusion 12112d as the tongue 12211d moves towards the end cover, thereby releasing the end cover from the base.Preferably, each first engagement mechanism 1211d further includes a recess 12111d located at an intermediate position of the first engagement mechanism, and the user can use the recess 12111d to press the tongue 12211d towards the end cover to release the end cover.

[0103] FIG. 33H exemplarily illustrates an elastic module engageable with a base and an end cover according to yet another preferred embodiment of the present invention, and FIG. 33I illustrates the compression structure of the elastic module. As shown in the drawing, the elastic module differs from the elastic modules illustrated in FIGS. 33A to 33G in that the elastic module includes a base 121e and an end cover 122e that can accommodate four spring packages. Similarly, the base 121e includes a pair of first engagement mechanisms 1211e located around its periphery, and the end cover 122e includes a pair of second engagement mechanisms 1221e located around its periphery. The spring packages are removably secured between the base 121e and the end cover 122e, and the base 121e and the end cover 122e are releasably engaged by the first engagement mechanisms 1211e and the second engagement mechanisms 1221e, allowing the spring packages to be compressed between the base and the end cover. The pair of first engagement mechanisms 1211e extend radially outward from the base 121e, each including a first protrusion 12112e positioned between the first engagement mechanism 1211e and the base 121e. The pair of second engagement mechanisms 1221e extend radially outward from the end cover 122e, each including a resilient tongue 12211e that can move toward and away from the end cover 122e, and a second protrusion 12212e positioned outside the tongue. The second protrusion 12212e can be joined to the first protrusion 12112e to engage the base and the end cover. As the tongue 12211e moves toward the end cover, the second protrusion 12212e disengages from the first protrusion 12112e, thereby releasing the end cover from the base.

[0104] Figures 33J to 33L exemplarily show a row of elastic modules shown in Figure 33A or 33H connected by flexible underpads 60a, 60b, and 60c, with the elastic modules secured to a first surface of the flexible underpad as shown in the drawings, and the flexible underpad can be folded to join a first portion of a second surface opposite the first surface to a second portion of the second surface as shown in Figures 33M and 33N. Figure 33P exemplarily shows an elastic cushion including the elastic module shown in Figure 33L and flexible underpad 60b or 60c.

As illustrated in the drawings, the elastic module includes a spring 110e, a base 121f, and an end cover 122f. The base 121f includes a spring mounting seat having a first spring mounting portion 1212f to which a first end of the spring can be secured. The end cover 122f includes a spring mounting seat having a second spring mounting portion 1222f to which a second end of the spring can be secured. A threaded locking assembly is installed between the base and the end cover, and the base and the end cover are releasably locked by the threaded locking assembly, thereby compressing a spring between the base and the end cover. Specifically, the threaded locking assembly includes one or more locking posts 127f installed on an outer region of the base and one or more arc-shaped openings 128f installed on corresponding outer regions of the end cover.
