Description

[Technical Field]

[0001] The present invention relates to the technical field of resilient cushions, and in particular to support underlays, resilient cushions and furniture. [Background technology]

[0002] Furniture such as beds and sofa beds are essential to people's lives. Most modern beds and sofa beds are equipped with elastic cushions. Elastic cushions have a certain degree of elasticity, and can provide a certain degree of elastic support when a person sleeps on a bed or sofa bed, providing a certain degree of comfort compared to hard cushions.

[0003] Current elastic cushions are generally one-piece cushions consisting of a bottom layer, a spring layer, a sponge stack, and side end sealing members, and are non-detachable and closed as a whole, i.e., the spring layer is placed on the bottom layer, the sponge stack is placed on the spring layer, and the side end sealing members are connected between the sponge stack and the bottom layer, thereby forming a closed space. However, in actual use, such elastic cushions are expensive, inconvenient to transport, and take up a large amount of space during storage. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to address at least some of the problems present in the prior art described above by improving the comfort of elastic cushions, while making them easier to transport and reducing the storage space they occupy.

At the same time, the elastic underlay body can be joined to the elastic support layer, further improving the elastic support function of the elastic cushion and improving comfort. In addition, the first and second joining structures are detachable, which makes it easy to store the support underlay and the elastic support layer, facilitating the transport of the elastic cushion and effectively reducing the space occupied by the elastic cushion during storage.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The elastic cushion and furniture of the present invention will now be described in detail with reference to the drawings. The preferred embodiments of the present invention have been described, and those skilled in the art may imagine 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.

[0031] First, referring to Figures 1, 9, 11, 17 and 23, the present invention provides a support underlay 1 configured for assembling an elastic cushion 2. The support underlay 1 includes an elastic underlay body 3. The underlay body 3 has an upper surface 4 and a lower surface 5 arranged opposite each other in the thickness direction. The upper surface 4 is used to contact an elastic support layer 7 that connects multiple elastic modules 6 of the elastic cushion 2, i.e., the upper surface 4 is used to set the elastic support layer 7. A first connecting structure 11 is formed on the upper surface 4, and the first connecting structure 11 is configured to be connected to a second connecting structure 12 formed on the lower surface of the elastic support layer 7, thereby restricting movement of the elastic support layer 7 in the lateral direction of the underlay body 3.

[0032] In the support underlay 1, the underlay body 3 is elastic, and a first connecting structure 11 is provided on the upper surface 4 of the underlay body 3 for connecting to a second connecting structure 12 formed on the underside of the elastic support layer 7. In this way, when the support underlay 1 is used to assemble the elastic cushion 2, the elastic support layer 7 is simply placed on the upper surface 4 of the underlay body 3. The connection between the first connecting structure 11 and the second connecting structure 12 limits the lateral movement of the elastic support layer 7 of the underlay body 3, improving the stability of the elastic support layer 7. At the same time, the elastic underlay body 3 can be connected to the elastic support layer 7, further improving the elastic support function of the elastic cushion 2 and improving comfort. In addition, the first connecting structure 11 and the second connecting structure 12 are detachable, which makes it easy to store the support underlay 1 and the elastic support layer 7, facilitating transportation of the elastic cushion 2, and effectively reducing the space occupied by the elastic cushion 2 during storage.

[0033] Incidentally, the lateral direction refers to the horizontal direction when the elastic cushion is deployed and installed, and includes the length direction and width direction of the underlay body 3.

[0034] In the supporting underlay 1, the first joint structures 11 may be located at any position on the upper surface 4. For example, in one embodiment, the first joint structures 11 may be located in the central region of the upper surface 4. In another embodiment, the first joint structures 11 may be located in the peripheral region of the upper surface 4. In another embodiment, referring to FIGS. 1 and 17, the first joint structures 11 are formed at the four corners of the upper surface 4, that is, the first joint structures 11 may be located at the corners of the upper surface 4. For example, FIGS. 1 and 17 show that the first joint structures 11 are installed at the four corners of the upper surface 4. In this way, the connection between the first joint structures 11 and the second joint structures 12 at the four corners of the upper surface 4 can restrict the lateral movement of the elastic support layer 7 of the underlay body 3 at the four corners, further improving the stability of the elastic support layer 7.

[0035] 1 and 17, in one embodiment, a plurality of first connecting structures 11 are spaced apart along the length of the underlay body 3 at a midpoint along the width direction of the underlay body 3. For example, the upper surface 4 includes a strip-shaped region 13 located at a midpoint along the width direction of the underlay body and extending along the length of the underlay body, with a plurality of first connecting structures 11 spaced apart along the length of the underlay body in the strip-shaped region 13. In this way, movement of the elastic support layer 7 in the lateral direction of the underlay body 3 can be further restricted along the length in the strip-shaped region 13 of the underlay body, and the connection of the first connecting structures 11 and the second connecting structures 12 at the four corners can further improve the stability of the elastic support layer 7.

[0036] In an alternative embodiment, the plurality of first joint structures 11 are spaced apart along the length of the underlay body only in the band-like regions 13, with no first joint structures 11 located at the four corners.

[0037] Furthermore, in the supporting underlay 1, the first connecting structures 11 may have various structural forms. However, regardless of the structural form adopted, it is only necessary that the first connecting structures 11 are connected to the second connecting structures 12 to restrict movement of the elastic support layer 7 in the lateral direction of the underlay body 3. For example, in one structural form of the first connecting structures 11, the first connecting structures 11 may be recesses formed on the upper surface 4, such that corresponding protrusions on the lower surface of the elastic support layer 7 can mate with the recesses, thereby restricting movement of the elastic support layer 7 in the lateral direction of the underlay body 3. Further, for example, in another structural form of the first joining structure 11, referring to Figures 1 and 17, the first joining structure 11 is a protrusion 10, and the protrusion 10 is configured to join with the internal space 14 of the corresponding elastic module 6, in this way, the integrity of the thickness of a portion of the underlay body 3 can be ensured, thereby further improving the elasticity of the underlay body 3, and at the same time, the internal space 14 of the elastic module 6 can be fully utilized as the second joining structure 12, and during assembly, when the elastic support layer 7 is laid on the upper surface 4 of the underlay body 3, the protrusion 10 is joined within the internal space 14 of the corresponding elastic module 6, thereby restricting the movement of the elastic support layer 7 in the lateral direction of the underlay body 3.

[0038] In one embodiment, the protrusions 10 may be independent members connected to the upper surface 4 by various connection forms (e.g., adhesive, hook-and-loop, or engagement), allowing the position of the protrusions 10 to be appropriately positioned according to actual needs. In another embodiment, the protrusions 10 and the underlay body 3 are integrally molded. For example, when molding the underlay body 3, the material of the underlay body 3 may be partially raised upward to form the protrusions 10. The supporting underlay 1 includes an enveloping layer 15 that envelops at least the upper and side surfaces of the underlay body 3 and the protrusions 10. In this way, the integrally molded structure and the enveloping layer 15 improve the integrity of the protrusions 10 and the underlay body 3, thereby making the connection between the protrusions 10 and the underlay body 3 more solid when the elastic support layer 7 is subjected to a lateral force, and effectively restricting the movement of the elastic support layer 7 in the lateral direction of the underlay body 3. In one embodiment, the covering layer 15 covers the entire underlay body 3 and the protrusions 10 .

[0039] 1 and 17, in one embodiment, the support underlay 1 further includes a handle 16 disposed on its outer periphery. The number of handles 16 may be one or more, for example, two or three. For example, FIGS. 1 and 17 show two spaced apart handles 16 disposed on one outer surface of the support underlay 1 in the longitudinal direction. In this manner, the handle 16 makes it easy to store and transport the support underlay 1. For example, the support underlay 1 can be folded or rolled up for collection, and the handle 16 allows the support underlay 1 to be easily transported.

[0040] In addition, in one embodiment, a connecting structure, such as a fastener, may be installed on the outer edge of the support underlay 1, and the connecting structure allows the support underlay 1 to be connected to the cushion layer 18 of the elastic cushion, for example, the cushion layer 18 and the support underlay 1 can be connected by a fastener.

[0041] 1 and 17, in one embodiment, the support underlay 1 further includes an underlay connecting structure 17 disposed on its outer periphery, which is configured to be connected to the cushion layer 18 of the elastic cushion 2 by an edge fastening structure 19, thereby forming the elastic cushion 2 into an elastic cushion without side end sealing members. That is, after the edge fastening structure 19 connects the outer edge of the cushion layer 18 (or a receiving ring extending from the underside of the cushion layer 18) to the underlay connecting structure 17, the sides of the elastic support layer 7 are open, i.e., the sides of the elastic support layer 7 can be observed from the outside, which effectively improves the breathability of the elastic cushion 2 and prevents mold caused by moisture inside the elastic cushion 2, which is more advantageous for areas with high humidity.

[0042] Furthermore, the peripheral fastening structure 19 may have various types. For example, in one type of the peripheral fastening structure 19, the peripheral fastening structure 19 may be a mesh body, with an upper edge of the mesh body connected to the outer edge (or receiving ring) of the cushion layer 18 and a lower edge of the mesh body connected to the underlay connection structure 17. Furthermore, in another type of the peripheral fastening structure 19, for example, referring to FIG. 12, the peripheral fastening structure 19 includes a plurality of fastening belts 23 spaced apart in the circumferential direction and releasably connected. Referring to FIG. 1, the underlay connection structure 17 includes connecting buckles 33 configured to be releasably joined to the fastening belts 23 of the peripheral fastening structure 19. Referring to FIGS. 12 and 13, the corresponding connecting buckles 33 and fastening belts 23 are releasably engaged with each other. Of course, in selectable types, the positions of the connecting buckles 33 and fastening belts 23 can be interchanged. Furthermore, for example, in another type of peripheral fastening structure 19, see FIGS. 18, 19, 20, and 21, the peripheral fastening structure 19 includes a plurality of fastening strings 21; see FIG. 17, the underlay connecting structure 17 includes hooks 20 configured to be releasably hooked onto the fastening strings 21 of the peripheral fastening structure 19; thus, see FIGS. 20 and 21, the fastening strings 21 can be connected to the hooks 20. Of course, in alternative types, the positions of the fastening strings 21 and the hooks 20 can be interchanged. Incidentally, the connection form of the fastening strings 21 is not limited to the connection form shown in the drawings. In addition to the connection form shown in the drawings, the fastening string 21 may have other connection forms. For example, in one connection form, the outer edge (or receiving ring) of the cushion layer is formed with a plurality of connecting buckles spaced apart in the circumferential direction, and the bottom outer edge of the support underlay 1 is formed with a plurality of fixing buckles spaced apart in the circumferential direction, and the plurality of connecting buckles and the plurality of fixing buckles are arranged alternately. In this case, the fastening string 21 can be extended up and down to be wound around each connecting buckle and fixing buckle in turn, thereby connecting the cushion layer and the support underlay together.

[0043] In a second aspect, the present invention provides an elastic cushion 2. See Figures 13, 14, 16, 21, 22, and 24. The elastic cushion 2 includes any of the support underlays 1 described above in the first aspect, an elastic support layer 7, and a cushioning layer 18. The elastic support layer 7 includes a plurality of elastic modules 6, which are arranged along the lateral direction of the elastic cushion 2. The elastic support layer 7 is placed on the upper surface 4 of the support underlay 1 such that the second connecting structure 12 formed on the lower surface of the elastic support layer 7 is connected to the first connecting structure 11 formed on the upper surface 4, thereby restricting movement of the elastic support layer 7 in the lateral direction of the underlay body 3. The cushioning layer 18 is laid on an equalizing cushion 22, and the cushioning layer 18 and the support underlay 1 are connected by an edge fastening structure 19.

[0044] As described above, by setting the elastic support layer 7 on the upper surface 4 of the underlay body 3 and joining the first joining structure 11 and the second joining structure 12, it is possible to restrict the movement of the elastic support layer 7 in the lateral direction of the underlay body 3 and improve the stability of the elastic support layer 7. At the same time, the elastic underlay body 3 cooperates with the elastic support layer 7 and the cushioning layer 18 to further improve the elastic support function of the elastic cushion 2 and increase comfort. In addition, the first joining structure 11 and the second joining structure 12 are detachable, and the edge fastening structure 19 is also detachable, which makes it easy to store the support underlay 1, the elastic support layer 7, and the cushioning layer 18, convenient for transporting the elastic cushion 2, and effectively reduces the space occupied by the elastic cushion 2 during storage.

[0045] 14 and 22, the elastic cushion 2 is formed without side sealing members by the edge fastening structure 19, that is, the edge fastening structure 19 allows the elastic cushion 2 to form an elastic cushion without side sealing members. After the edge fastening structure 19 connects the cushion layer 18 and the support underlay 1, the sides of the elastic support layer 7 are open, that is, the sides of the elastic support layer 7 can be observed from the outside, thus effectively improving the breathability of the elastic cushion 2 and preventing mold caused by moisture inside the elastic cushion 2, which is more advantageous for humid regions.

[0046] Also, in one embodiment, as described above, the peripheral fastening structure 19 includes a releasably connected fastening string 21 or fastening belt 23. For example, referring to Figures 12 and 13, the corresponding connecting buckle 33 and fastening belt 23 are releasably engaged. Referring to Figures 20 and 21, the fastening string 21 can be connected to the hook 20.

[0047] Furthermore, in order to facilitate the assembly of the elastic support layer 7 of the elastic cushion 2 and improve the efficiency of the assembly of the elastic cushion 2, in one embodiment, as shown in FIGS. 2 to 6, the elastic cushion 2 includes a plurality of elastic module cells 24. As shown in FIG. 2, each elastic module cell 24 includes a fixed substrate 25 and a plurality of elastic modules 6 mounted on the fixed substrate 25. As shown in FIG. 4, the fixed substrates 25 are configured to be removably connected together along the lateral direction of the elastic cushion. As shown in FIG. 6, the plurality of elastic module cells 24 assemble the elastic support layer 7. In this way, by connecting the fixed substrates 25 of the plurality of elastic module cells 24, the elastic support layer 7 can be quickly and easily assembled. As shown in FIG. 6, the fixed substrates 25 may be connected together in various ways, such as by screw connection, engagement, or hook-and-loop connection. For example, in one connection configuration, a connection groove 34 and a connection buckle 35 are formed on the opposing sides of each fixed substrate 25, and the connection groove 34 of one fixed substrate 25 engages with and aligns with the connection buckle 35 of the adjacent other fixed substrate 25, thereby connecting and joining the multiple fixed substrates 25 in order. Also, in the elastic module cell 24 of Figure 3, the multiple elastic modules 6 in the fixed substrate 25 are formed into a single row of elastic modules 6. Therefore, the fixed substrate 25 of each elastic module cell 24 may have a single row of elastic modules 6 or multiple rows of elastic modules 6.

[0048] 2, in one embodiment, when the first connecting structure 11 is a protrusion 10, the fixed substrate 25 is formed with a position limiting opening 26 that corresponds to and communicates with the internal space 14 of each elastic module 6. Referring to FIGS. 11 and 23, the protrusion 10 enters and connects to the internal space 14 of the elastic module 6 through the position limiting opening 26. In this way, the connection between the position limiting opening 26 and the protrusion 10 on the fixed substrate 25 and the connection between the protrusion 10 and the internal space 14 can further restrict the movement of the elastic support layer 7 in the lateral direction of the underlay body 3 and further improve the stability of the elastic support layer 7.

[0049] In one embodiment of the elastic cushion 2, the elastic cushion 2 further includes an equalizing cushion 22, which is laid on the plurality of elastic modules 6 and joins the upper portions of the plurality of elastic modules 6 so as to limit movement of the elastic modules in the lateral direction of the equalizing cushion, and the cushioning layer 18 is laid on the equalizing cushion 22. In this way, the joining of the first joining structure 11 and the second joining structure 12 limits movement of the elastic support layer 7 in the lateral direction of the underlay body 3, and at the same time, the equalizing cushion 22 limits movement of the plurality of elastic modules 6 of the elastic support layer 7 in the lateral direction of the equalizing cushion 22, thereby further improving the stability of the elastic support layer 7. At the same time, the elastic underlay body 3 cooperates with the elastic support layer 7, the equalizing cushion 22, and the cushioning layer 18 to further improve the elastic support function of the elastic cushion 2 and improve comfort. In addition, the first connecting structure 11 and the second connecting structure 12 are detachable, and the edge fastening structure 19 is also detachable, which makes it easy to store the support underlay 1, the elastic support layer 7, the balancing cushion 22, and the cushion layer 18, makes it convenient to transport the elastic cushion 2, and effectively reduces the space occupied by the elastic cushion 2 when stored.

[0050] Also, in one embodiment, referring to Figures 7, 8, 10 and 15, the balancing cushion 22 includes a cushion body 27, the underside of which faces the elastic support layer 7 has a plurality of spaced apart accommodating holes 28 formed therein, and each portion of the plurality of elastic modules 6 is accommodated and positioned within a corresponding one of the plurality of accommodating holes 28, thereby holding the balancing cushion 22 on the plurality of elastic modules 6; the upper side of the cushion body 27, facing away from the elastic support layer 7, has a plurality of spaced apart buffer holes 29 formed therein, and the plurality of buffer holes 29 are configured to form a buffer layer portion 30 on the upper side of the cushion body 27, of which, in the thickness direction of the balancing cushion 22, each buffer hole 29 and a corresponding one of the accommodating holes 28 are separated by a partition portion 31 of the cushion body 27. In this way, each receiving hole 28 receives a portion of a corresponding elastic module 6, thereby supporting the equalizing cushion 22 on multiple elastic modules 6 so as to limit the lateral movement of the elastic modules 6 of the equalizing cushion 22, significantly improving the stability of the multiple elastic modules 6 of the elastic cushion 2. At the same time, the buffering holes 29 can distribute the support force of the elastic modules in the corresponding receiving holes 28 to the four circumferential areas of the buffering holes 29 via the partitions 31, thereby preventing the user from feeling any obvious hard support points of the elastic modules 6 on the top surface of the equalizing cushion 22 and further improving comfort. In addition, the buffering layer 30 can significantly improve the buffering and comfort performance of the equalizing cushion 22 by accommodating air in the multiple buffering holes 29, and it is sufficient to lay a thin cushioning layer 18 on the equalizing cushion 22. Therefore, the balancing cushion 22 improves the stability and comfort of the elastic cushion 2, reduces the cost of the elastic cushion 2, and at the same time, the balancing cushion 22 and the elastic module 6 can be easily attached, which makes it easy to transport the elastic cushion 2 and reduces the space occupied during storage.

[0051] In one embodiment, the receiving holes 28 and the buffering holes 29 may be offset, i.e., each receiving hole 28 is arranged to partially overlap with a corresponding buffering hole 29, for example, the central axis of the receiving hole 28 and the central axis of the buffering hole 29 do not overlap. In another embodiment, referring to FIG. 15 , each receiving hole 28 and its corresponding buffering hole 29 are arranged to have the same axis, i.e., the axes are aligned but not connected to each other. In this way, each receiving hole 28 and its corresponding buffering hole 29 can share the same complete hole bottom wall (i.e., partition 31), and the buffering hole 29 can further distribute the support force of the elastic module 6 in the corresponding receiving hole 28 to the four circumferential areas of the buffering hole 29 via the partition 31. This prevents the elastic module 6 from being felt as a hard support point on the upper surface of the balancing cushion 22, further improving comfort. In addition, by sharing the same bottom wall for the accommodation hole 28 and the buffer hole 29, air can circulate between the accommodation hole 28 and the buffer hole 29, improving the ventilation effect of the balancing cushion 22. For example, if the balancing cushion 22 is made of sponge, air can circulate more easily, and if the balancing cushion 22 is made of rubber or silica gel, multiple ventilation holes are formed on the bottom wall of the hole to provide a short air flow path.

[0052] In one embodiment, the receiving hole 28 may have various shapes, for example, a circular hole or a rectangular hole, and the part of the elastic module 6 received in the receiving hole 28 may also have a circular or rectangular shape. In another embodiment, referring to Fig. 15, the inner surface of the receiving hole 28 has a conical surface that gradually widens outward as it faces downward. For example, the receiving hole 28 is a conical hole with its larger diameter end facing downward and its smaller diameter end facing upward. In this way, referring to Fig. 15, the conical surface of the receiving hole can be attached to the inclined outer surface of the conical elastic module 6, thereby providing support between the inclined inner peripheral surface and the bottom surface of the receiving hole 28. Thus, the balancing cushion 1 is more firmly supported on the multiple elastic modules 6.

[0053] In one embodiment, the buffering holes 29 may have various shapes, for example, circular or rectangular holes. In another embodiment, referring to Fig. 15, the inner surface of the buffering holes 29 has a conical surface that gradually widens outward as it approaches the upper surface. For example, the buffering holes 29 are conical holes with their larger diameter ends facing upward and their smaller diameter ends facing downward. In this way, when the upper surface of the elastic cushion is subjected to pressure, the conical surface of the buffering holes 29 allows the portion surrounding the buffering holes 29 on the upper surface to be compressed more stably, preventing lateral tilt and further improving the balance of the buffering.

[0054] In the embodiment shown in Fig. 15, the cushioning layer 18 and the balancing cushion 22 may be separate components. In one embodiment, referring to Fig. 23, the balancing cushion 22 and the cushioning layer 18 are formed as a one-piece cushion 32, which may or may not include the buffer holes 29 described above; in other words, referring to Figs. 20 and 21, the one-piece cushion 32 is connected to the support underlay 1 by a peripheral fastening structure 19.

[0055] In one embodiment, to improve the comfort of the elastic cushion 2, supports are installed between the elastic modules 6 in the peripheral region of the elastic cushion 2 in the circumferential direction of the elastic cushion 2. In this way, the supports in the peripheral region of the elastic cushion 2, together with the elastic modules 6 in the peripheral region, can effectively improve the support strength of the peripheral region of the elastic cushion 2, preventing a user from feeling like the edges of the elastic cushion 2 are sinking in when sitting on the elastic cushion 2. The peripheral region of the elastic cushion 2 and the inner region of the elastic cushion 2 can provide essentially the same support hardness, thereby significantly improving the consistency of the support function of the elastic cushion 2. For example, supports are inserted and installed between adjacent elastic modules 6 in the circumferential direction in the elastic cushion 2's outermost one circumference, or between adjacent elastic modules 6 in each of the outermost two circumferences of the elastic cushion 2. Various types of supports may be provided, as long as they can be inserted and installed between adjacent elastic modules 6. For example, the support may be a rubber post or other structural elastic module, such as an inverted cone-shaped elastic body.

[0056] The elastic module 6 may also be a spring module, a rubber module, or a silica gel module.

[0057] The elastic cushion 2 can be used for various purposes, such as an outdoor cushion and an indoor cushion, for example, an elastic mattress, a sofa cushion, a chair cushion, and a bench cushion.

[0058] In a third aspect, the present invention provides furniture, which includes any of the elastic cushions 2 described in the second aspect. As described above, the elastic cushion 2 allows the furniture to have good stability and comfort while reducing costs, thereby improving overall quality.

Based on the teachings of the present invention, those skilled in the art can easily recognize that alternative structures of the structures disclosed in the present invention can be realized as alternatives, and that the embodiments disclosed in the present invention can be combined to create new embodiments, all of which are within the scope of the appended claims.
