Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of elastic cushions, and in particular to an elastic module storage rack, an elastic module storage apparatus, an elastic cushion, a furniture, and elastic module use method.BACKGROUND

[0002] Furniture like beds and sofa beds are essential components in the daily life of human people, most of which are provided with elastic cushions. The elastic cushions generally have a certain elasticity to provide an elastic support when people are lying on the beds or sofa beds. As such, the elastic cushions can provide a higher comfort than a hard pad.

[0003] The existing elastic cushion is typically a non-detachably integrated and enclosed pad consisting of a base layer, a spring layer, a sponge overlaying layer and an enclosed side surrounding cover. Specifically, the spring layer is disposed on the base layer, the sponge overlaying layer is disposed on the spring layer, and the enclosed side surrounding cover are connected between the sponge overlaying layer and the base layer, thereby forming a closed space. However, such an elastic cushion generally has a planar upper surface, and thus an additional pillow has to be used to support the head when a user is resting on the elastic cushion. Further, the elastic cushion incurs a relatively high cost, and exhibits poor performance in stability, thereby reducing comfort of the elastic cushion. Moreover, the elastic cushion is inconvenience to transport, and would occupy a large storage space during its actual use.SUMMARY

[0004] In view of at least some problems existing in the prior art, the objective of the present disclosure is to enable the elastic cushion to provide a good support to the head and the body of the user, so as to improve the comfort of the elastic cushion while facilitating transportation thereof and effectively reducing the occupied storage space when stored.

[0005] According to a first aspect of the present disclosure, the above objective is achieved by providing an elastic module storage rack which comprises: a bottom plate having an upper surface and a lower surface arranged opposite to each other in a height direction of the elastic module storage rack; and a placement seat disposed on the upper surface and extending in the height direction, wherein the elastic module storage rack can be switched between a first use state and a second use state, wherein in the first use state, the placement seat is configured to allow a lowermost elastic module in a plurality of elastic modules nested and stacked successively to be positioned on the placement seat, such that the plurality of elastic modules nested and stacked successively can be stored on the elastic module storage rack; and in the second use state, the elastic module storage rack can be placed on the elastic modules in such a way that the placement seat faces the plurality of elastic modules, such that the elastic module storage rack can be used as a pillow unit, with the lower surface facing upwards as a head support surface of the pillow unit.

[0006] In the technical solution according to the present disclosure, the elastic module storage rack comprises a bottom plate and a placement seat, and in the first use state, the placement seat is configured (e.g. facing upwards) to allow the lowermost one in the plurality of elastic modules nested and stacked successively to be positioned thereon for storage, and in the second use state, the elastic module storage rack is placed on the elastic module, and the lower surface of the bottom plate faces upwards so that it can be used as the head support surface of the pillow unit. Therefore, when the elastic module storage racks are assembled into the elastic cushion, the plurality of elastic modules of the elastic cushion can be removed from the placement seats of the respective elastic module storage racks and then be assembled into the elastic support layer. Afterwards, each of the elastic module storage racks is switched to the second use state such that the placement seat of each of the elastic module storage racks faces downwards and can be supported on the corresponding elastic module. This allows the elastic module storage rack to act as the pillow unit. At this time, the lower surface of the bottom plate faces upwards and acts as the head support surface of the pillow unit, and the pillow unit is higher than the remaining elastic modules. Thereafter, the pad layer of the elastic cushion can be laid over the elastic support layer and cover the respective pillow units. Consequently, a headrest portion is formed on the pad layer via the respective pillow units, so that the resulting elastic cushion can provide a good support to the head and the body. When the user is lying on the elastic cushion, his or her head can be supported on the headrest portion, which can effectively improve the comfort of the elastic cushion. In addition, when the elastic cushion is to be collected for storage, the pad layer can be removed off the elastic cushion and gathered up, the respective elastic module storage racks are switched to the first use state, and then the respective elastic modules are detached and nested and stacked successively on the respective placement seats. Therefore, the elastic cushion can be easily stored and transported, and the storage space for accommodating the elastic cushion can be reduced greatly.

[0007] According to one embodiment, a top portion of the placement seat comprises an engagement structure configured to engage a top portion of the elastic module so that the placement seat is allowed to be supported on the elastic module.

[0008] According to another embodiment, the engagement structure comprises a recess portion formed on the top portion of the placement seat and configured to have a shape that matches a shape of the top portion of the elastic module, such that, in the second use state, the recess portion can be reliably nested onto the top portion of the elastic module.

[0009] According to a further embodiment, the placement seat is designed to be adjustable in height according to a user's need.

[0010] According to a further embodiment, the placement seat is of a frame structure.

[0011] According to a further embodiment, the placement seat comprises a top portion body, a bottom portion body disposed on the bottom plate, and a plurality of support bars connected between the top portion body and the bottom portion body, wherein the plurality of support bars is spaced apart from each other in a circumferential direction of the placement seat, such that the top portion body is kept of a predetermined distance from the bottom plate.

[0012] According to a further embodiment, each of the support bars comprises at least two bar sections that are connected successively so as to be adjustable in an extension or contraction length therebetween.

[0013] According to a further embodiment, the top portion body is formed with a recess portion recessed inwards and extending towards the bottom portion body, such that the top portion body is formed as a cylinder that can be sleeved onto the top portion of the elastic module. A wall surface of the cylinder is formed with a plurality of through openings spaced apart in the circumferential direction , and each of the through openings extends from a sidewall of the cylinder to a bottom wall of the cylinder, wherein each of the support bars is connected at one end to an upper edge of a corresponding through opening.

[0047] Reference now will be made to the drawings to describe in detail elastic module storage rack and storage apparatus, elastic cushion and use method thereof, and furniture according to the present disclosure. What will be described herein only cover preferred embodiments of the present disclosure, and those skilled in the art would envision, on the basis of the preferred embodiments, other possible manners which also fall into the scope described herein.

[0048] It is worth noting that, despite an elastic module storage apparatus 16 shown in Fig. 1, in some embodiments, the elastic module storage apparatus 16 can be formed by six elastic module storage racks 1 provided by the present disclosure. For example, bottom plates 2 of the six elastic module storage racks 1 are formed integrally as one piece. Therefore, the elastic module storage apparatus 16 in Fig. 1 can be separated into six elastic module storage racks 1 independent of one another, wherein each elastic module storage rack 1 includes a bottom plate 2 and a placement seat 5 thereon. However, it would be appreciated that the number of placement seats 5 on a bottom plate 2 of the elastic module storage rack 1 provided by the present disclosure is not limited to one, i.e., a bottom plate 2 may be provided thereon with a placement seat 5, or a plurality of (e.g. two or three) placement seats 5 spaced apart from each other.

[0049] In the first aspect, referring to Figs. 1-5, Fig. 8, Figs. 16 and 17, the elastic module storage rack 1 provided by the present disclosure comprises a bottom plate 2 and a placement seat 5, wherein the bottom plate 2 comprises an upper surface 3 and a lower surface 4 arranged opposite to each other in the height direction of the elastic module storage rack 1, and the placement seat 5 is disposed on the upper surface and extends in the height direction (for example, the placement seat 5 may be a separate component connected onto the upper surface 4, or the placement seat 5 may be formed integrally with the bottom plate 2 as one piece). The elastic module storage rack 1 can be switched (e.g., flipped, or the like, for example, in an ascending or descending manner in the height direction of the placement seat 5) between a first use state (Fig. 1) and a second use state (Fig. 2). In the first use state, the placement seat 5 is configured to allow the lowermost elastic module 6 in the plurality of elastic modules 6 nested and stacked successively to be positioned on the placement seat 5, such that the plurality of elastic modules 6 nested and stacked successively can be stored on the elastic module storage rack 1. In the second use state, the elastic module storage rack 1 can be placed on the elastic module 6 in such a way that the placement seat 5 faces the plurality of elastic modules 6. For example, the placement seat 5 faces downwards to allow itself to be supported on the elastic module 6; in the case, the elastic module storage rack 1 acts as the pillow unit 7, with the lower surface 4 facing upwards as a head support surface of the pillow unit 7.

[0050] In said technical solution, since the elastic module storage rack 1 comprises a bottom plate 2 and a placement seat 5, and can be switched (for example, flipped) between the first use state where the placement seat 5 allows the lowermost one in the plurality of elastic modules 6 nested and stacked successively to be positioned thereon for storage, and the second use state where the elastic module storage rack 1 is placed on the elastic module 6, and the lower surface 4 of the bottom plate faces upwards so that it can be used as the head support surface of the pillow unit 7. Therefore, when the elastic module storage racks 1 are assembled into the elastic cushion 14, the plurality of elastic modules 6 of the elastic cushion 14 can be removed from the placement seats 5 of the respective elastic module storage racks 1 and then be assembled into the elastic support layer 19. Afterwards, each of the elastic module storage racks 1 is switched to the second use state such that the placement seat 5 of each of the elastic module storage racks 1 faces downwards and can be supported (e.g. supported while facing downwards) on the corresponding elastic module 6. This allows the elastic module storage rack 1 to act as the pillow unit 7. At this time, the lower surface 4 of the bottom plate 2 faces upwards and acts as the head support surface of the pillow unit 7, and the pillow unit 7 is higher than the remaining elastic modules 6 of the elastic support layer 19. Thereafter, the pad layer 15 of the elastic cushion 14 can be laid over the elastic support layer 19 and cover the respective pillow units 7. Consequently, a headrest portion is formed on the pad layer via the respective pillow units (e.g. the respective pillow units 7 arranged in a sequence), so that the resulting elastic cushion 14 can provide a good support to the head and the body. When the user is lying on the elastic cushion 14, his or her head can be supported on the headrest portion, which can effectively improve the comfort of the elastic cushion. In addition, when the elastic cushion 14 is to be collected for storage, the pad layer 15 can be removed off the elastic cushion and gathered up or rolled up, the respective elastic module storage racks 1 are switched to the first use state, and then the respective elastic modules 6 are detached and nested and stacked successively on the respective placement seats 5. Therefore, the elastic cushion 14 can be easily stored and transported, and the storage space for accommodating the elastic cushion 14 can be reduced greatly.

[0051] In some embodiments, in the second use state of the elastic module storage rack 1, the placement seat 5 can be directly placed and supported on the elastic module 6, and when the pad layer 15 and the elastic support layer 19 of the elastic cushion 14 are connected, the elastic module storage rack 1 is clamped and positioned on the elastic module 6. In some other embodiments, referring to Figs. 1, 2 and 3, the top portion of the placement seat 5 comprises an engagement structure configured to engage the top portion of the elastic module 6 so that the placement seat 5 is allowed to be stably and reliably supported on the elastic module 6. As such, with the engagement with the top portion of the elastic module 6 by means of the engagement structure when the elastic module storage rack 1 is in the second use state, the present disclosure can further improve the stability and reliability of the elastic module storage rack 1 supported on the elastic module 6.

[0052] Moreover, the engagement structure may be of various types as long as it can engage the top portion of the elastic module 6. For example, in some embodiments, the engagement structure may be a hook-and-loop fastener which can be attached to the top surface of the elastic module 6. Further, the top surface of the elastic module 6 may also be provided with a hook-and-loop fastener. In the case, the two hook-and-loop fasteners can be attached to each other, to further improve the stability and reliability of the elastic module storage rack 1 supported on the elastic module 6. In some other embodiments, the engagement structure may be a protrusion, for example, a circular protrusion, which can be configured to mate with the recess on the top portion of the elastic module 6, thereby also improving the stability and reliability of the elastic module storage rack 1 supported on the elastic module 6. In other embodiments, referring to Figs. 1-3, the engagement structure includes a recess portion 8 formed on the top portion (e.g. the top surface) of the placement seat 5, the shape of the recess portion 8 matches the shape of the top portion of the elastic module 6 such that the recess portion 8 can be reliably nested onto the top portion of the elastic module 6 when the elastic module storage rack 1 is in the second use state. In the case, the recess portion 8 can be directly located inside the placement seat 5, to thus reduce the size of the placement seat 5, and meanwhile, the top profile of the elastic module 6 can be directly used to engage the recess portion 8, to cause the top portion of the elastic module 6 to be directly received within the recess portion 8 of the placement seat 5, which can further improve the stability and reliability of the elastic module storage rack 1 supported on the elastic module 6.

[0053] In some embodiments, the placement seat 5 may be of a fixed height. Therefore, the headrest portion can be adapted to the user's need for a fixed height of the head support. In some other embodiments, the height of the placement seat 5 can be adjusted, i.e., the placement seat 5 is designed to be adjustable in height according to the user's need for the headrest height such that the same user can adjust the height of the headrest portion according to the needs at different stages. In addition, different users can also adjust the height of the headrest portion according to different needs, so as to improve the comfort. If it is required to adjust the height of the headrest portion, the user can disengage the pad layer 15 from the elastic support layer 19 at the headrest portion, then adjust the height of the placement seat 5 to the desired height, and then connect the pad layer 15 with the elastic support layer 19.

[0054] The height of the placement seat 5 can be adjusted in multiple manners. For example, in an adjustment manner, the placement seat 5 may include a plurality of (e.g. two or three) sleeves that are nested and stacked successively and can be extended or contracted to a desired position; the height of the placement seat 5 can be adjusted by extending or contracting the sleeves to a desired position. In a further adjustment manner, the height of the placement seat 5 can be adjusted by means of the support bars 10 mentioned below (which will be detailed hereinafter).

[0055] In some embodiments, the placement seat 5 may be a solid body, for example, a solid circular truncated cone. In some other embodiments, the placement seat 5 may be of a frame structure. In the case, with the frame structure, the placement seat 5 is a non-solid body, i.e., a hollow cavity is formed inside the placement seat 5, to thus effectively reduce the whole weight of the elastic module storage rack 1. Moreover, with the support structures connected via the frame structure, the present disclosure can enhance the overall strength of the elastic module storage rack 1 while reducing the weight.

[0056] The frame structure may be of various types. For example, in some embodiments, the placement seat 5 includes a plurality of L-shaped support bars. The plurality of L-shaped support bars are inversed on the bottom plate 2, i.e., the plurality of L-shaped support bars are connected at the tips of the short sides thereof and located in the center, and the long sides of the plurality of L-shaped support bars are spaced apart in the circumferential direction and connected onto the bottom plate 2, such that the plurality of L-shaped support bars are distributed radially. In this way, an inner hollow cavity is enclosed between the plurality of L-shaped support bars and the bottom plate 2, and the placement seat 5 is thus formed with a frame structure. In some other embodiments, referring to Fig. 1, the placement seat 5 includes a top portion body 9, a bottom portion body 27 disposed on the bottom plate 2, and a plurality of support bars 10 connected between the top portion body 9 and the bottom portion body 27. The support bars 10 are spaced apart from each other along the circumferential direction of the placement seat 5 such that the top portion body 9 is kept of a predetermined distance from the bottom plate 2, that is the top portion body 9 and the bottom plate 2 have a predetermined gap therebetween. Accordingly, the top portion body 9, the bottom portion body 27 and the plurality of support bars 10 form a frame structure. In other embodiments, the placement seat 5 comprises a top portion body 9, and a plurality of support bars 10 spaced apart circumferentially, wherein the plurality of support bars 10 is connected at one end to the bottom plate 2 while connected at the other end to the top portion body 9, such that the top portion body 9 and the bottom plate 2 have a predetermined gap therebetween. In the case, an inner cavity is formed among the top portion body 9, the plurality of support bars 10 and the bottom plate 2, and the placement seat 5 is formed as a frame structure accordingly.

[0057] In some embodiments, each support bar 10 in the plurality of support bars 10 has a fixed length, and the headrest portion therefore can be adapted to the user's need for the fixed height of the head support. In some other embodiments, each support bar 10 comprises at least two bar sections that are connected successively so as to be adjustable in extension or contraction length therebetween, and the height of the placement seat 5 therefore can be adjusted by extending or contracting the bar sections, as described above. In this way, the same user can adjust the height of the headrest portion according to the needs at different stages. In addition, different users can also adjust the height of the headrest portion according to their personalized needs, so as to improve the comfort.

[0058] In some embodiments, the top surface of the top portion body 9 is a flat surface. Alternatively, in some other embodiments, referring to Fig. 1, the top portion body 9 is formed with a recess portion 8 recessed inwards and extending towards the bottom portion body, such that the top portion body 9 is formed as a cylinder that can be sleeved onto the top portion of the elastic module 6. In the second use state, the recess portion 8 is used to sleeved onto the top portion of the elastic module 6. In the case, the recess portion 8 can be directly located within the placement seat 5, thus reducing the size of the placement seat 5, and meanwhile, the top profile of the elastic module 6 can be used directly, allowing the top portion of the elastic module 6 to be directly received within the recess portion 8 of the top surface of the placement seat 5, which can further improve the stability and reliability of the elastic module storage rack 1 supported on the elastic module 6. A wall surface of the cylinder is formed with a plurality of through openings 28 spaced apart in the circumference direction, wherein each through opening extends from the sidewall 29 of the cylinder to the bottom wall 30 of the cylinder. Each support bar 10 at one end is connected to an upper edge 31 of a corresponding through opening, i.e., in the radial direction, one end of each support bar 10 is located in a through opening corresponding thereto. Accordingly, the end of the support bar 10 can support the upper edge of the through opening, which can significantly enhance the strength of the top portion body 9, and improve the stability and reliability of the headrest portion.

[0059] In some embodiments, referring to Fig. 1, the bottom plate 2 is formed with an opening 11 extending through the bottom plate 2, i.e., the opening 11 extends through the upper surface 3 and the lower surface 4. The opening 11 is partitioned into a plurality of opening parts by connection bars 12 extending radially, and the placement seat 5 is disposed on the mouth edge of the opening 11, i.e., the opening 11 is provided therein with radially extending connection bars 12, and the placement seat 5 is disposed around the mouth edge of the opening 11. In this way, the opening 11 can reduce the weight of the bottom plate 2 while the connection bars 12 can improve the support performance of the headrest portion. In addition, the number of the connection bars 12 may be one or more. For example, a plurality of connection bars 12 can be arranged crosswise to form a mesh structure, or the plurality of connection bars 12 may be spaced apart and parallel to one another, or the plurality of connection bars 12 may be connected at one end to the center of the opening 11 and form a radial shape.

[0060] In some embodiments, referring to Figs. 6, 7 and 8, the bottom plate 2 further comprises lifting straps 13 detachably arranged on two opposite sides of the bottom plate. After an elastic module set (i.e., the plurality of elastic modules nested and stacked successively) is positioned on the placement seat 5, the lifting straps 13 on the two sides are tied together, to limit the elastic module set stored on the elastic module storage rack 1, and are then lifted up, to facilitate transportation.

[0061] In some embodiments, the bottom plate 2 at each end is provided with a lifting strap 13, and the lifting strap 13 at both ends are connected respectively to the two opposite ends of the bottom plate 2. As such, the lifting straps 13 at the two ends of the bottom plate 2 can be tied together. In some other embodiments, referring to Fig. 6, the bottom plate 2 comprises long sides opposite to each other, and on each long side, the two ends of the lifting strap 13 are detachably connected respectively to the same long side and close to the two ends thereof, i.e., on each long side of the bottom plate 2, the two ends of the lifting strap 13 are connected to the same side of the bottom plate 2 and have a gap therebetween. Therefore, the lifting straps 13 on the two sides of the bottom plate 2 can be tied together.

[0062] In some embodiments, the lifting straps 13 on two sides are configured to bind the collected pad layer 15 of the elastic cushion 14 between the lifting straps 13. For example, if the elastic cushion is to be stored, the pad layer 15 can be collected (e.g. folded or rolled up) into the collected state, the collected pad layer 15 is placed above the stacked elastic modules and between the lifting straps 13. In this way, the lifting straps 13 can bind the pad layer 15 and the stacked elastic modules together, for ease of storage and transportation.

[0063] The lifting strap 13 may be a non-elastic strap, for example, a canvas belt. Alternatively, the lifting strap 13 may be an elastic strap, for example, a rubber strap.

[0064] In a second aspect, referring to Figs. 1-5, 8, 16 and 17, the present disclosure provides an elastic module storage apparatus 16 comprising a plurality of elastic module storage racks 1 of any one described above in the first aspect, wherein a plurality of bottom plate 2 can be detachably spliced together to form a spliced body 17, and a plurality of placement seats 5 are located on the same side of the spliced body 17.

[0065] As described above, the plurality of bottom plates 2 is detachably spliced together to form the spliced body 17 of the elastic module storage apparatus 16, and the plurality of placement seats 5 are located on the same side of the spliced body 17. In the second use state, the spliced body 17 is located upwards with its lower surface as a headrest support surface. Therefore, when the elastic module storage apparatus 16 is used in the assembly of the elastic cushion 14, the plurality of elastic modules 6 of the elastic cushion 14 can be removed from the placement seats 5 of the respective elastic module storage racks and then assembled into the elastic support layer 19. Afterwards, one or more elastic module storage apparatuses 16 are switched to the second use state such that the placement seats of the respective elastic module storage apparatuses face downwards and are supported on the corresponding elastic modules. Consequently, the lower surface of the spliced body faces upwards and can act as the head support surface. Accordingly, the elastic module storage apparatus is higher than the remaining elastic modules. Then, the pad layer of the elastic cushion can be laid over the elastic support layer to cover the elastic module storage apparatus. With the elastic module storage apparatus, a headrest portion can be formed on the pad layer. Therefore, the elastic cushion can provide a good support to the head and body. When a user is lying on the elastic cushion, the head can be supported by the headrest unit, which can effectively improve the comfort of the elastic cushion. In addition, when the elastic cushion is to be stored, the pad layer can be detached off and collected, and the elastic module storage apparatus is switched to the first use state where the respective elastic modules can be removed and then nested and stacked successively on the corresponding placement seats. Accordingly, the elastic cushion can be easily stored and transported, and thus can effectively reduce the storage space of the elastic cushion.

[0066] In some embodiments, as described above, the plurality of bottom plates 2 may be components independent of one another, and can be spliced together to form the spliced body 17, such that the plurality of placement seats 5 are located on the same side of the spliced body 17.

[0067] In some other embodiments, referring to Fig. 1, the plurality of bottom plates 2 are formed integrally such that the spliced body 17 can be formed as one piece. In the case, the one piece includes a plurality of placement seats 5. For example, in some embodiments, the one piece may be a strip panel, and the plurality of placement seats 5 are spaced apart on one side surface of the strip panel to form a single row of placement seats 5. Of course, a plurality of rows of placement seats 5 can be formed as required.

[0068] In some embodiments, referring to Figs. 6, 7 and 8, two opposite sides of at least two of the separated bottom plates 2 are disposed with lifting straps 13, and when the spliced body 17 is formed as one piece, lifting straps 13 are provided on two opposite sides of the one piece. After a plurality of elastic module sets (i.e., a plurality of elastic modules nested and stacked successively) are respectively positioned on the corresponding placement seats 5, the lifting straps 13 on the two sides cannot only be tied together to limit the elastic module sets but also be lifted for transportation.

[0069] In some embodiments, the spliced body 17 (or the one piece) on each end is provided with a lifting strap 13, and the two ends of the lifting straps 13 are connected respectively to the two opposite sides of the bottom plate 2. Therefore, the lifting straps 13 on both ends can be tied together. In some other embodiments, referring to Fig. 6, the spliced body 17 includes two opposite long sides. On each long side of the spliced body 17, the two ends of the lifting straps 13 are connected detachably to the same long side and have a gap therebetween, i.e., on each long side of the spliced body 17, the two ends of the lifting straps 13 are connected to the same side of the spliced body 17 and have a gap therebetween. As such, the lifting straps 13 on the two sides of the bottom plate 2 can be tied together.

[0070] In some embodiments, the lifting straps 13 on two sides of the spliced body 17 (or the one piece) are configured to bind the pad layer 15 of the collected elastic cushion 14 between the lifting straps 13. For example, when the elastic cushion is to be stored, the pad layer 15 is collected (e.g. folded or rolled up) into the collected state, and then placed above the plurality of stacked elastic module sets and between the lifting straps 13. In this way, the lifting straps 13 can bind the pad layer 15 and the stacked elastic modules together, for ease of storage and transportation. In addition, the lifting strap 13 may be a non-elastic strap, for example, a canvas strap. Alternatively, the lifting strap 13 may be an elastic strap, for example, a rubber strap.

[0071] In a third aspect, the present disclosure provides an elastic cushion 14. Referring to Figs. 11-13, 16 and 17, the elastic cushion 14 comprises a pad layer 15, a headrest body 18, and a plurality of elastic modules 6, wherein the plurality of elastic modules 6 can be spliced together in the transverse direction of the elastic cushion and assembled into the elastic support layer 19; the headrest body 18 can be supported on a part of the elastic modules 6 and is higher than the remaining elastic modules 6 (i.e., the top surface of the headrest body 18 is higher than the remaining elastic modules 6); the pad layer 15 can be laid fixedly over the headrest body 18 and the remaining elastic modules 6, such that the pad layer 15 can be formed thereon with a headrest portion via the headrest body 18, i.e. the headrest body 18 can form a headrest portion of the pad layer 15.

[0072] In such elastic cushion 14, since the elastic cushion 14 comprises the headrest body 18 that is supported on a part of the elastic modules 6 and has a location higher than the remaining elastic modules 6, and the pad layer 15 is laid fixedly over the headrest body 18 and the remaining elastic modules 6, thereby forming a headrest portion on the pad layer 15 via the headrest body 18. In this way, the elastic cushion 14 can provide a good support to the head and the body. When a user is lying on the elastic cushion 14, the head can be supported on the headrest portion, thereby effectively improving the comfort of the elastic cushion. Moreover, when the elastic cushion 14 is to be stored, the pad layer 15 can be removed off and collected (e.g. rolled up), and the respective elastic modules 6 can be gathered up (e.g. nested and stacked successively). Therefore, the elastic cushion 14 according to the present disclosure can be easily stored and transported, and thus can effectively reduce the storage space of the elastic cushion.

[0073] In some embodiments, the elastic cushion 14 has a stored state where the headrest body 18 is configured to allow the lowermost elastic module 6 in the plurality of elastic modules 6 nested and stacked successively to be positioned on the headrest body 18, such that the plurality of elastic modules 16 nested and stacked successively can be stored on the headrest body 18, i.e., the plurality of elastic modules 16 are nested and stacked successively, and the lowermost elastic module 6 is sleeved on the headrest body 18. In this way, the present disclosure can offer convenience in storing a plurality of elastic modules 6, and can effectively reduce the occupied storage space of the elastic cushion 14.

[0074] In the elastic cushion 14, the headrest body 18 may be of multiple types. For example, for a first type of the headrest body 18, the headrest body 18 includes a positioning portion that can extend into the gap between the adjacent elastic modules 6. After the positioning portion extends into the gap between the adjacent elastic modules 6, the headrest body 18 is disposed on the elastic support layer 19 in a manner of being higher than the remaining elastic modules 6.

[0075] For a second type of the headrest body 18, the headrest body 18 includes a plurality of the elastic module storage racks 1 according to any one of the above item of the first aspect, wherein each elastic module storage rack 1 corresponds to a respective one of the plurality of elastic modules 6. The elastic cushion 14 has a stored state and a deployed state. In the stored state, the plurality of elastic modules 6 corresponding to each elastic module rack 1 are nested and stacked successively, and the lowermost elastic module 6 is sleeved on the placement seat 5, such that the plurality of elastic modules 6 nested and stacked successively are stored on the corresponding elastic module storage rack 1. In the deployed state, all the elastic modules 6 are assembled into the elastic support layer 19, the plurality of placement seats 5 face downwards and are arranged and supported successively on the corresponding elastic modules 6, the plurality of bottom plates 2 face upwards such that a plurality of pillow units 7 are arranged to form a headrest body 18 that is higher than the remaining elastic modules 6, and the pad layer 15 is laid fixedly over the headrest body 18 and the remaining elastic modules 6. After the plurality of elastic modules 6 is spliced in the transverse direction of the elastic cushion to form the elastic support layer 19, the plurality of elastic module storage racks 1 are respectively supported on the corresponding elastic modules 6 according to the desired width and length of the headrest portion, and act as the headrest body 18. After the pad layer 15 is laid over the headrest body 18 and the remaining elastic modules 6, a headrest portion with the desired width and length is formed on the pad layer 15. In this way, the headrest portion can be formed flexibly as required.

[0076] For a third type of the headrest body 18, referring to Fig. 11, the headrest body 18 is the elastic module storage apparatus 16 according to any one of the above item of the second aspect. The elastic cushion 14 has a stored state and a deployed state. In the stored state, a plurality of elastic modules 6 corresponding to each elastic module storage rack 1 are nested and stacked successively, and the lowermost elastic module 6 is sleeved on the placement seat 5, such that the plurality of elastic modules 6 nested and stacked successively are stored respectively on the corresponding elastic module storage racks 1. In the deployed state, all the elastic modules 6 are assembled into an elastic support layer 19, a plurality of placement seats 5 face downwards and are supported respectively on the corresponding elastic modules 6, the spliced body 17 faces upwards, causing the headrest body 18 to be higher than the remaining elastic modules 6, and the pad layer 15 is fixedly laid over the headrest body 18 and the remaining elastic modules 6. After the plurality of elastic modules 6 are spliced in the transverse direction of the elastic cushion to form the elastic support layer 19, bottom plates 2 of the required number of the elastic module storage racks 1 are spliced according to the desired width and length of the headrest unit, to form the spliced body 17. With the spliced body 17, the required number of elastic module storage racks 1 can be formed as one piece, and the one piece is supported on the corresponding elastic modules 6 to act as the headrest body 18. After the pad layer 15 is laid over the headrest body 18 and the remaining elastic modules 6, a headrest portion with the desired width and length is formed on the pad layer 15. As such, a headrest body can be formed flexibly as required. For the third type, since a plurality of bottom plates 2 are spliced together, there is a pulling and limiting effect among the plurality of elastic module storage racks 1, thereby significantly improving the stability of the headrest body 18.

[0077] In some embodiments, the elastic cushion 14 may include a bottom layer, the bottom layer is formed thereon with multiple rails spaced apart in parallel, and a plurality of elastic modules 6 can be slid and accommodated between the adjacent rails, to thus form an elastic support layer 19. In some other embodiments, referring to Figs. 9, 10 and 11, the elastic cushion 14 includes a plurality of elastic module units 20 each including a base plate 21 and a plurality of elastic modules 6 disposed thereon. The plurality of base plates 21 can be detachably spliced together in the transverse direction of the elastic cushion, such that the plurality of elastic module units 20 can be assembled into an elastic support layer 19. By assembling the plurality of elastic module units 20, the present disclosure can improve the assembling efficiency of the elastic support layer 19, and can facilitate storage of the plurality of elastic module units 20. In addition, the base plate 21 is not limited to the arrangement shown in Fig. 9. For example, a plurality of elastic modules 6 forms an elastic module set in a row form, and the base plate 21 may be provided with two or three rows of elastic module sets.

[0078] The plurality of base plates 21 can be detachably spliced together in the transverse direction using multiple splicing methods. The splicing methods include, but are not limited to, the following splicing methods. For example, in some splicing methods, adjacent base plates 21 can be attached to each other by means of hook and loop fasteners. Alternatively, in some splicing methods, adjacent base plates 21 can be spliced together by means of a slider and a sliding groove. For example, one of the adjacent base plates 21 is formed with a slider while the other is formed with a corresponding sliding groove, and with the slide fit between the slider and the sliding groove, the two adjacent base plates 21 can be spliced together. Alternatively, in some splicing methods, adjacent base plates 21 can be spliced together by means of an engagement structure. For example, the engagement structure includes a male engagement member and a female engagement member. One of the adjacent base plates 21 is formed with a male engagement member while the other is formed with a corresponding female engagement member, and the male engagement member can engage the female engagement member, to splice the two adjacent base plates 21 together. Any one of the splicing methods can be employed as long as the adjacent base plates 21 are spliced detachably. Therefore, the specific splicing method is not limited therein.

[0079] In some embodiments, referring to Fig. 9, the base plate 21 is formed thereon with nesting openings, wherein each nesting opening is provided with an elastic module 6. Referring to Fig. 7, a plurality of elastic modules 6 of an elastic module unit 20 can pass through a nesting opening of a further elastic module unit 20 and extend into respective elastic modules 6. In this way, a plurality of elastic module units 20 can be nested and stacked successively, to further improve the storage convenience and reduce the occupied space.

[0080] In some embodiments, referring to Fig. 13, the outer edge of the pad layer 15 and the bottom outer edge of the elastic support layer 19 are connected via an edge fastening structure 22. Therefore, with the edge fastening structure 22, the pad layer 15 and the elastic support layer 19 can be fastened and connected, to thus improve the stability of the headrest portion.

[0081] In some embodiments, in order to improve the stability of the respective elastic modules 6, referring to Fig. 13, a stop ring 23 extending towards the elastic module 6 is disposed at the edge of the lower surface of the pad layer 15, and the stop ring 23 and the bottom outer edge of the elastic support layer 19 are connected via the edge fastening structure 22. Therefore, after the stop ring 23 is tightened via the edge fastening structure, the stop ring 23 can effectively prevent the elastic module 6 at the edge of the elastic support layer 19 from moving in the transverse direction, thereby improving the stability and the comfort of the elastic cushion.

[0082] In some embodiments, the edge fastening structure 22 may be a side enclosure cloth that can be connected at the upper edge and the lower edge respectively to the outer edge (or the stop ring 23) of the pad layer 15 and the bottom outer edge (or the base plate 21) of the elastic support layer 19 by means of a zipper structure.

[0083] In some embodiments, referring to Figs. 13, 16 and 17, the elastic cushion 14 can be formed as an elastic cushion with fully open sides by means of the edge fastening structure 22, i.e. without a sealed and closed side enclosure. In other words, after the edge fastening structure 22 connects the outer edge (or the stop ring 23) of the pad layer 15 with the bottom outer edge (or the base plate 21) of the elastic support layer 19, the side of the elastic support layer 19 is exposed, i.e., the side of elastic support layer 19 can be observed from the outside. In this way, the present disclosure can effectively improve the breathability of the elastic cushion 14 and prevent the elastic cushion 14 from getting damp or even moldy, which is more advantageous in areas with humid climates.

[0084] The edge fastening structure 22 may be of multiple types. For example, for a type of the edge fastening structure 22, the edge fastening structure 22 may be a mesh, wherein the mesh is connected at the upper edge to the outer edge (or the stop ring 23) of the pad layer 15, and connected at the lower edge to the bottom outer edge (or the base plate 21) of the elastic support layer 19. For another example, for a further type of the edge fastening structure 22, referring to Figs. 13, 16 and 17, the edge fastening structure 22 comprises a releasably connectable connection rope 24. It would be appreciated that the connection method of the connection rope 24 is not limited to the one shown in the drawings. In addition to the one shown in the drawings, the connection rope 24 may have other connection methods. For example, in a connection method, a plurality of connection buttons spaced apart in the circumferential direction is formed on the outer edge (or the stop ring 23) of the pad layer 15, a plurality of fixing buttons spaced apart in the circumferential direction is formed on the bottom outer edge (or the base plate 21) of the elastic support layer 9, and the plurality of connection buttons and the plurality of fixing buttons are arranged alternately. In the case, the connection rope 24 extends up and down to wrap around each connection button and each fixing button in sequence, thereby connecting the pad layer 15 and the elastic support layer 19. For another example, in a further connection method, a plurality of connection ropes 24 spaced apart in the circumferential direction is formed on one of the pad layer 15 and the elastic support layer 19, while a plurality of corresponding fixing buttons is formed on the other of the pad layer 15 and the elastic support layer 19. Therefore, each connection rope 24 can be hung on the corresponding fixing button thereby connecting the pad layer 15 with the elastic support layer 19.

[0085] In some embodiments, referring to Figs. 14 and 15, the pad layer 15 has a rolled state, where the collected pad layer 15 is bound between the lifting straps 13 of the headrest body 18, so as to facilitate storage of the elastic cushion.

[0086] In some embodiments, the pad layer 15 may include a plurality of pad blocks 25 connected detachably to each other, and when the pad layer 15 is to be collected, the plurality of pad blocks 25 are removed and then stacked successively. In some other embodiments, referring to Fig. 15, the pad layer 15 is a material layer that can be folded or rolled up. In the case, the pad layer 15 is collected after folded or rolled up.

[0087] In order to further facilitate folding or roll-up of the pad layer 15, referring to Fig. 13, the pad layer 15 includes a plurality of pad blocks 25 arranged in the length direction of the elastic cushion, wherein adjacent pad blocks 25 are connected via a thinned soft hinge. With the soft hinge, the pad layer 15 can be collected conveniently.

[0088] The soft hinge may be of multiple types. For example, the soft hinge may be a connection cloth. Alternatively, the soft hinge includes a groove 26 formed on the upper surface and / or lower surface of the pad layer 15 and extending along the width direction of the elastic cushion. With the groove 26, the present disclosure can enable the pad layer 15 to be easily folded or rolled up, and can facilitate an integral connection between the pad blocks 25.

[0089] The elastic module 6 may be a spring module, rubber module or silicone module.

[0090] The elastic cushion 14 may be applied in any desired scenario. For example, the elastic cushion 14 may be used as an outdoor or indoor mat. For example, the elastic cushion 14 may be used as an elastic mattress, a sofa pad, a chair pad or a bench pad.

[0091] In a fourth aspect, the present disclosure provides a furniture comprising the elastic cushion 14 described in any of the third aspect above. As described above, with the elastic cushion 14, the present disclosure can provide a good stability and a high comfort while reducing the furniture cost, thus improving the overall quality.

[0092] In a fifth aspect, the present disclosure provides an elastic cushion use method comprising the step of: splicing a plurality of elastic modules together in a transverse direction of the elastic cushion to assemble an elastic support layer when deploying an elastic cushion; switching (e.g. flipping) a headrest body from a first use state to a second use state, and supporting a placement seat of the headrest body on a part of the elastic modules (e.g. supporting the placement seat downwards on a part of the elastic modules) to cause the headrest body to be higher than the remaining elastic modules; and laying the pad layer over the headrest body and the remaining elastic modules, such that the pad layer can be formed thereon with a headrest portion via the headrest body; and removing the pad layer and the headrest body when the elastic cushion is rolled up; switching (e.g. flipping) the headrest body to the first use state, such that the placement seat of the headrest body to face upwards; nesting and stacking successively the plurality of elastic modules, and then positioning a lowermost elastic module on the placement seat 5, such that the plurality of elastic modules nested and stacked successively are stored on the headrest body.

[0093] According to the above-described technical solution, a headrest portion can be formed on the pad layer with the headrest body. Therefore, the elastic cushion can provide a good support to the head and the body. When a user is lying on the elastic cushion, the head can be supported on the headrest portion, which can effectively improve the comfort of the elastic cushion. In addition, when the elastic cushion is to be stored, the pad layer can be removed and rolled up, and the respective elastic modules can be nested and stacked successively on the headrest body. As such, the elastic cushion can be stored and transported easily, while significantly reducing the storage space of the elastic cushion.

[0094] In some embodiments, the elastic cushion use method further comprises a step of folding or rolling the removed pad layer when the elastic cushion is collected, and binding the folded or rolled pad layer between lifting straps of the headrest body. In this way, the lifting straps can bind the pad layer and the stacked elastic modules together, to facilitate storage and transportation.

[0095] The scope of protection of the present disclosure is defined only by the appended claims. Given the teaching of the present disclosure, those skilled in the art could easily envision using alternative structures of those disclosed herein as feasible alternative embodiments, and combining the embodiments disclosed herein to form new embodiments, which should all fall into the scope defined by the appended claims.
