Description

[Technical Field]

[0001] The present invention relates to the technical field of storing elastic cushions, and more particularly to a storage case for storing elastic cushions and an elastic cushion device. [Background technology]

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

[0003] Current elastic cushions are usually one-piece cushions consisting of an integral bottom layer, a spring layer, a sponge stack layer, and a closed side end sealing member and cover, which are non-detachable and closed, i.e., the spring layer is installed on the bottom layer, the sponge stack layer is installed on the spring layer, and the closed side end sealing member cover surrounds the sponge stack layer and the bottom layer, thereby forming an elastic cushion with a closed space inside.

[0004] However, such elastic cushions are relatively uncomfortable when actually used. Furthermore, such elastic cushions are not only expensive, but also relatively unstable when actually used, resulting in low comfort, inconvenient to transport, and require a large amount of space for storage. Furthermore, the covers are inconvenient to wash. Furthermore, such elastic cushions must be placed in a fixed location and cannot be removed and stored, and cannot be transported to a desired location according to the user's needs, for example, cannot be transported outdoors for outdoor activities.

At the same time, by carrying the storage case 24, the elastic cushion 2 can be carried wherever necessary according to the user's needs, and the space used for storing the elastic cushion 2 can be effectively reduced. When it is necessary to use the elastic cushion 2, the storage case 24 is opened, and each elastic cushion member is removed and then assembled into an elastic cushion.

[0075] In some embodiments, the sidewall of the storage case 24 may be straight, with the locking structure 25 attached to the straight sidewall and protruding from the straight sidewall. In other embodiments, as shown in FIG. 19, the sidewall of the storage case 24 has at least one recess 26 recessed toward the storage space, with the locking structure 25 attached to each recess 26. That is, the locking structure 25 is located within the recess 26. Thus, most or all of the locking structure 25 may be located within the recess 26, protected by the recess 26 and preventing the locking structure 25 from being subjected to wear or impact, thereby improving the durability of the storage case 24.

[0076] 19 and 27, the storage case 24 includes a connecting side edge 27 that connects the upper body 33 and the underbody 34 with a hinge, a locking side edge 28 that is disposed opposite the connecting side edge 27, and locking end edges 29 that are disposed opposite the connecting side edge 27 and the locking side edge 28 on both sides of the connecting side edge 27 and the locking side edge 28, wherein the connecting side edge 27 is provided with a plurality of hinge structures that connect the upper body 33 and the underbody 34 with a hinge, the locking side edge 28 is provided with a plurality of locking structures 25 that are disposed at intervals in the extension direction of the locking side edge 28, and each locking end edge 29 is provided with at least one locking structure 25. In this manner, the upper body 33 and the underbody 34 can be stably and reliably locked together by the plurality of locking structures 25 at the locking side edges 28 and at least one locking structure 25 at each locking end edge 29 .

[0077] 19, 20, and 27, in some embodiments, to facilitate transport of the storage case 24, a side handle 30 is provided on the locking side edge 28, and the side handle 30 straddles at least one intermediate locking structure 25 along the extension direction of the locking side edge 28. In this way, the side handle 30 allows the user to easily lift the storage case while also protecting the at least one intermediate locking structure 25.

[0078] Furthermore, the storage case 24 may be provided with multiple types of locking structure 25, and any type of locking structure 25 may be used as long as it can open and close the upper body 33 and the underbody 34. For example, in one type of locking structure 25, referring to Fig. 23, the locking structure 25 includes a locking catch 31 and a locking plate 32, the locking catch 31 is installed on one of the upper body 33 and the underbody 34 of the storage case 24, and one end of the locking plate 32 is installed so as to be pivotable on the other of the upper body 33 and the underbody 34. For example, in Fig. 23, the locking catch 31 is installed on the underbody 34, and one end of the locking plate 32 is installed so as to be pivotable on the upper body 33, and the other end of the locking plate 32 is curved outward in an arc shape, thereby forming a locking plate tilt-up portion 35 that makes it easy for a user to apply force to swing the locking plate, and the locking plate 32 is formed with a locking hook 36 that can be attached to and detached from the locking catch 31. In this way, the user can lock or release the lock hook 36 and the lock catch 31 by applying a pressing force or a releasing force to the tilt-up portion 35 .

[0079] The storage case 24 provided by the present invention may have multiple structures. For example, in some embodiments of the first type of storage case 24, as shown in FIGS. 20, 21, and 22, at least one locking end edge 29 of the storage case 24 is provided with casters 37, and at least the other opposing locking end edge 29 is provided with an end handle 38. In this manner, a user can easily grasp the end handle 38 and pull the storage case 24 to transport the elastic cushion to any desired location. For example, in some embodiments, one locking end edge 29 of the storage case 24 is provided with casters 37, and the other opposing locking end edge 29 is provided with an end handle 38. Furthermore, for example, in some embodiments, one locking end edge 29 of the storage case 24 is provided with casters 37 and an end handle 38, and the other opposing locking end edge 29 is provided with casters 37 and an end handle 38. In this way, the storage case 24 can be pulled by either end handle 38. Also, when all casters 37 are in contact with the ground, the storage case 24 can be pushed, and two people can lift the storage case 24 by using the two end handles 38 on both locking end edges 29.

[0080] 37 and 38, in some embodiments of the second type storage case 24, at least one locking end edge 29 of the storage case 24 is provided with casters 37, for example, two casters 37, and the other locking end edge 29 is provided with an extendable drawbar 46. In this way, a user can extend the drawbar 46 to a required length according to their needs and then pull the storage case 24 by the drawbar 46 to move it. For example, in some embodiments, one locking end edge 29 of the storage case 24 is provided with casters 37, and the other opposite locking end edge 29 is provided with an extendable drawbar 46. In some other embodiments, casters 37 are also installed on both opposing locking end edges 29 of the storage case 24, and in this case, the casters 37 on both locking end edges 29 may be the same or different, and an extendable pull rod 46 is installed on either of the locking end edges 29, so that the storage case 24 can be pushed and moved when the casters 37 on both locking end edges 29 contact the ground.

[0081] Furthermore, in the storage case of the present invention, the drawbar 46 may have multiple structures. For example, in one type of structure of the drawbar 46, the drawbar 46 may be a T-shaped bar, with the vertical bar of the T-shaped bar being an extendable bar that may be fixed to the bottom of the underbody of the storage case 24, and the horizontal bar of the T-shaped bar being a gripping bar for the user to hold. Furthermore, in another type of structure of the drawbar 46, as shown in Figures 37 and 38, the drawbar 46 is a U-shaped bar 47, with two extendable support bar assemblies 48 of the U-shaped bar 47 installed on two side edges in the width direction of the underbody 34, respectively, and extending toward opposite locking end edges 29, and the horizontal bar of the U-shaped bar 47 being a gripping bar for the user to hold. In this way, the two support rod assemblies 48 significantly improve the support strength of the bottom of the underbody 34, allowing the storage case 24 to have a greater predetermined height, and creating a larger storage space inside. Furthermore, when the storage case 24 having a greater predetermined height is placed horizontally, the storage case 24 can be used as a support table, allowing the user to place necessary items on the top surface of the upper body 33.

[0082] In some embodiments, to facilitate transportation of the storage case, as shown in Figures 35, 36, and 37, lift structures 49 are provided on opposing sides of the underbody 34, which are releasably joined to each other. Thus, a user can lift the storage case using the lift structures 49 to facilitate transportation. Also, restraint structures 50 are provided on opposing sides of the storage case 24, which are releasably joined to each other. A restraint space 51 surrounded by the restraint structures 50 on both sides is intended to restrain the cushion layer 15 in a rolled-up state of the elastic cushion. In this way, the cushion layer 15 of the elastic cushion can be wrapped in a cylindrical shape, placed in the restraint space 51, and then fixed by the restraint structures 50. This allows the cushion layer 15 to be effectively stored and facilitated transportation.

[0083] In some embodiments, the lifting structure 49 and the restraining structure 50 may be located at different positions in different storage cases. In some embodiments, referring to FIG. 37, when the lifting structures 49 on both sides are joined together, a storage space 52 located above the upper body 33 is enclosed, and the restraining structure 50 is located within the storage space 52. In this way, the storage space 52 can be effectively utilized to position the restraining structure 50. In addition, the restraining space 51 formed by the restraining structure 50 may be located within the storage space 52 or outside the storage space 52.

[0084] In some embodiments, the restraining structures 50 on both sides may be installed on the storage case 24, for example, on the upper body 33 or the underbody 34. In some embodiments, as shown in FIG. 37, the restraining structures 50 on both sides are installed on the corresponding lifting structures 49. In this way, the restraining structures can be installed effectively using the lifting structures 49, and the connection between the restraining structures and the lifting structures 49 can improve the strength of the lifting structures. Furthermore, the restraining structures on both sides can be restrained against the lifting structures 49 after being joined together. Even if the lifting structures 49 on both sides are not joined together, the restraint by the lifting structures 49 can prevent the unjoined lifting structures 49 from scattering from each other, making it convenient for the user to hold the lifting structures on both sides together.

[0085] Furthermore, in the storage case of the present invention, the lifting structure 49 and the restraining structure 50 may have a variety of structures, as long as any of these structures is adopted and the above-described contents are realized. For example, in some embodiments, referring to Fig. 37, the lifting structure 49 on each side includes a U-shaped lifting strap 53, one end of two connecting strips 54 of the U-shaped lifting strap 53 is attached to the side of the underbody 34, and the U-shaped lifting straps 53 on both sides are releasably joined together, and the restraining structures 50 on both sides include restraining belts 55 located on both sides, the mutually distant ends of the restraining belts 55 are connected to the corresponding connecting strips 54, and the mutually facing ends of the restraining belts 55 are provided with releasable fastening structures, and at least one of the restraining belts 55 on both sides has an adjustable length, so that the length of the restraining belt can be adjusted as needed. In this way, the user can easily lift the storage case by using the U-shaped lift straps 53 on both sides, and at the same time, when necessary, the cushion layer of the elastic cushion can be easily restrained by the restraining belts 55 on both sides. The releasable fastening structure may include a belt, a Velcro fastener, a snap-engagement groove, or any other fastening connection structure.

[0086] In some embodiments, in order to improve the stability of the storage of the elastic cushion 2, a recess (not shown) is formed in the bottom wall of the storage space, and the nesting assembly 39 formed by sequentially nesting multiple elastic module units 1 removed from the elastic cushion 2 together has at least its bottom contained and positioned within the recess. In this way, the recess limits the position of at least the bottom of the nesting assembly 39, further improving the stability of the storage of the elastic cushion 2.

[0087] In some embodiments, an elastic shielding portion is formed on the side wall of the storage space. The elastic shielding portion may be an elastic block (e.g., a rubber block or a spring) or a spring and a shielding plate (not shown), and the shielding plate may be connected to the side wall of the storage space by the spring. The elastic shielding portion is configured to shield the internal space of each elastic module 4 of the elastic module unit 1 located at the bottom among the elastic module units 1 nested together in sequence in the elastic cushion. Thus, referring to Figures 25 and 26, the internal space of each elastic module 4 may be used as an item mounting space 40 for placing additional items. In this way, when storing the elastic cushion, additional items such as bottles, lamps, fuel cans, pots, air pumps, and / or stoves can be placed in the corresponding item mounting spaces 40, thereby increasing the number of items that can be carried and improving the space utilization rate of the elastic cushion within the storage space.

[0088] 39 to 48, some embodiments of the third storage case 24 of the present invention include a caster 37 mounted on at least one end edge and a lift member 57 pivotable about a pivot connection point 56, where the lift member 57 is configured to be pivotable to one of a retracted position, a raised position, and a retracted position. For example, as shown in FIG. 43, a user can move the storage case 24 by pivoting the lift member 57 to the retracted position and bringing the caster 37 into contact with the ground. For example, as shown in FIG. 45, a user can lift the storage case 24 by pivoting the lift member 57 to the raised position. For example, as shown in FIG. 47, a user can pivot the lift member 57 to the retracted position, thereby reducing the storage space required for the lift member 57 and making it easier to store or nest the storage cases 24.

[0089] Incidentally, the third form of the storage case 24 of the present invention includes the embodiments shown in Figures 39 to 48, but is not limited to these embodiments, and the lift member 57 may be pivoted to any one of the pulling position, the lifted position, and the retracted position.

[0090] Also, in some embodiments, when the lift members 57 are in the tensioned position, the lift members 57 may extend diagonally upward in a forward-facing direction, i.e., the lift members 57 are disposed at an angle relative to the top surface 240 of the storage case 24. In other embodiments, when the lift members 57 are in the tensioned position, the lift members 57 are parallel to the top surface 240 of the storage case 24, making it easier for a user to pull and move the storage case 24. For example, in FIG. 42 , the lift members 57 extend generally horizontally forward, and in FIG. 43 , the lift members 57 extend generally vertically upward.

[0091] Furthermore, when the lift member 57 is in the raised position, the grip bar 570 of the lift member 57 may be located at any suitable position on the storage case 24 to allow the user to lift the storage case 24. For example, in some embodiments, when the lift member 57 is in the raised position, the grip bar 570 of the lift member 57 is located at an end of the storage case 24. Furthermore, for example, in some embodiments, when the lift member 57 is in the raised position, the grip bar 570 of the lift member 57 is located above the middle of the storage case 24. In this way, when the user lifts the storage case 24, the portions of the storage case 24 located on both sides of the grip bar 570 are relatively balanced, which makes it easier for the user to lift the storage case 24 in a more balanced and convenient manner.

[0092] Furthermore, when the lift member 57 is in the retracted position, the gripping bar 570 of the lift member 57 can be positioned at any suitable position, thereby reducing the storage space of the lift member 57 as much as possible, thereby facilitating the storage or nesting of the storage case 24. For example, in some embodiments, the lift member 57 may be close to the top surface 240 of the storage case 24 to provide an appropriate gap between the top surface 240 and the lift member 57. Furthermore, for example, in some embodiments, referring to FIG. 47 , when the lift member 57 is in the retracted position, the gripping bar 570 of the lift member 57 contacts the top surface 240 of the storage case 24, thereby further reducing the storage space of the lift member 57 and thus allowing the storage case 24 to be nested or placed within a suitable storage space. Furthermore, in some embodiments, the storage case 24 may be formed with a recess (not shown) that fits the shape of the gripping bar 570, for example, an extending recess formed in the top surface 240. In this way, when in the retracted position, the gripping bar 570 is positioned within the recess so that the gripping bar 570 is flush with the outer surface of the storage case 24, thereby preventing the gripping bar 570 from protruding from the outer surface of the storage case 24.

[0093] Furthermore, in the storage case 24, the lift member 57 may be held in the tension position, lift position, or retracted position by a variety of configurations, and the present invention includes, but is not limited to, the structures in the examples of Figures 43 to 48. For example, in some embodiments, the lift member 57 may be attached to the body of the storage case 24 by a pivot structure 58, for example, to the upper body 33 or the underbody 34, and the pivot structure 58 includes, but is not limited to, the structure in the example of Figure 48. The pivot structure 58 may include a position limiting structure (for example, a releasable ratchet and pawl structure or a structure consisting of a pin and a plurality of pin holes spaced apart circumferentially), and when the lift member 57 is pivoted to the tension position, lift position, or retracted position, positioning and position retention can be achieved by the position limiting structure (for example, by the ratchet and pawl structure or by inserting a pin into a pin hole at a corresponding position). Furthermore, for example, in some embodiments, the storage case 24 further includes a releasable first stop structure 60, which may be independent of the pivot structure 58, and which is configured to hold the lift member 57 in the tensioned position. In this manner, the first stop structure 60 can prevent the lift member 57 from pivoting in the tensioned position, thereby making it convenient for a user to easily grasp the lift member 57.

[0094] Furthermore, the first stop structure 60 may have multiple types, including, but not limited to, the structures shown in the examples of FIGS. 43 and 44. For example, in some embodiments, the first stop structure 60 includes a releasable pin screw and pin hole mating structure, one of which is formed in the lift member 57 and the other of which is formed in the body (e.g., the upper body 33 or the underbody 34) of the storage case 24, such that when the pin screw is inserted into the pin hole, the lift member 57 can be held in the tensioned position. When the lift member 57 needs to be pivoted to the lift position or the retracted position, the pin screw can be removed from the pin hole, allowing the lift member 57 to pivot to the lift position or the retracted position.

[0095] 43 and 44, for example, in some embodiments, the first stopper structure 60 includes a fixed base 601, a first pull tab 602, a first stopper strip 603, and a first lifting hook 604, and the fixed base 601, the first pull tab 602, the first stopper strip 603, and the first lifting hook 604 include, but are not limited to, the structure shown in FIG. 44, wherein the fixed base 601 and the first lifting hook 604 are spaced apart, and the first stopper strip 603 is pivotally connected to the first pull tab 602 on the body of the storage case 24, for example, the underbody 34, and the first pull tab 602 is pivotally installed on the fixed base 601, and when the first pull tab 602 pivots, it can move with the first stopper strip 603, and when the first pull tab 602 is in the released position, the first stopper strip 603 moves with it ... The stopper strip 603 can be disengaged from the first lifting hook 604, and at this time, the lift member 57 can be pivoted to the lift position or pivoted away from the lift position. For example, after the lift member 57 is pivoted to the lift position, the first stopper strip 603 can be allowed to be hooked onto the first lifting hook 604. Meanwhile, referring to FIG. 44, when the first pull handle 602 is pivoted to the locking position, the first stopper strip 603 and the first lifting hook 604 are locked, and the lift member 57 can be clamped by the first stopper strip 603 in the pulling position. When the first pull handle 602 is pivoted in the opposite direction to the release position, the first stopper strip 603 and the first lifting hook 604 can be unlocked, and the first stopper strip 603 can be disengaged from the first lifting hook 604, thereby allowing the lift member 57 to be disengaged from the first stopper strip 603. In this manner, the user can easily hold the lift member 57 in the lift position or pivot the lift member 57 away from the lift position by simply pushing the first pull tab 602 to bring the first stopper strip 603 along to lock or disengage with the first lifting hook 604.

[0096] Furthermore, the first stopper strip 603 may be a single stopper strip, or the first stopper strip 103 may include multiple stopper strips connected together, for example, the first stopper strip 103 is a U-shaped stopper strip, two side strips of the U-shaped stopper strip are connected to the first pull tab 602, and one horizontal strip of the U-shaped stopper strip can be locked or unlocked with respect to the first lifting hook 604.

[0097] Furthermore, the fixed base 601 and the first lifting hook 604 may be independent members and arranged at an interval, or the first lifting hook 604 may be fixed and installed on the fixed base 601, or the first lifting hook 604 and the fixed base 601 may be formed as an integrated member.

[0098] In some embodiments, the storage case 24 further includes a releasable second stop structure 61, which is independent of the pivot structure 58 and is configured to allow the lift member 57 to pivot between a raised position and a retracted position when cooperating with the lift member 57. In this manner, a user can conveniently lift the storage case 24 by pivoting the lift member 57 to the raised position, for example, to move the storage case 24 to a predetermined position. When it is necessary to move the storage case 24 to a predetermined position or to store the storage case 24, the user can pivot the lift member 57 to the retracted position, thereby reducing the space usage of the lift member 57.

[0099] In some embodiments, the lift member 57 can be positioned and held in a raised position or a retracted position, allowing a user to pivot between the raised and retracted positions simply by manually pushing the lift member 57. In some embodiments, the second stop structure 61 is configured to allow the lift member 57 to pivot from the raised position to the retracted position under the action of gravity, and also to pivot from the retracted position to the raised position under the action of a lifting force applied by the user. In this way, the lift member 57 can pivot from the raised position to the retracted position under the action of gravity, effectively improving ease of use.

[0100] Furthermore, the second stop structure 61 may have multiple types, including, but not limited to, the structures shown in the examples of FIGS. 46 and 48. For example, in some embodiments, the second stop structure 61 includes a releasable pin screw and pin hole mating structure, one of which is formed in the lift member 57 and the other is formed in the body (e.g., the upper body 33 or the underbody 34) of the storage case 24, so that when the pin screw is inserted into the pin hole, the lift member 57 can be held in the retracted position or the lifted position. When the lift member 57 needs to pivot, the pin screw can be removed from the pin hole, allowing the lift member 57 to pivot to the lifted position or the retracted position.

[0101] Further, for example, in some embodiments, referring to FIGS. 46 and 48, the second stopper structure 61 includes a fixed plate 610, a second pull tab 611, a second stopper strip 612, and a second lifting hook 613, and the fixed plate 610, the second pull tab 611, the second stopper strip 612, and the second lifting hook 613 include, but are not limited to, the structures shown in FIGS. 46 and 48, wherein the second pull tab 611 is pivotally installed on one end of the fixed plate 610, the second lifting hook 613 is installed on the other end of the fixed plate 610, and the second stopper strip 612 is pivotally connected to the second pull tab 611, and when the second pull tab 611 pivots, the second stopper strip 612 can move along with it. When the second pull handle 611 is in the release position, the second stopper strip 612 is hooked onto the second lifting hook 613 and connected thereto; when the second pull handle 611 is pivoted to the locking position, the second stopper strip 612 is locked to the second lifting hook 613, and a clamping space 614 is formed between the second stopper strip 612 and the fixed plate 610, through which the lifting member 57 can pivot between the raised position and the retracted position; when the second pull handle 611 is pivoted to the release position, the second stopper strip 612 is unlocked from the second lifting hook 613, and the lifting member 57 can escape from the clamping space 614. The clamping space 614 allows the lifting member 57 to pivot from the raised position to the retracted position under the effect of gravity.

[0102] In addition, the second stopper strip 612 may be a single stopper strip, or the second stopper strip 612 may include multiple stopper strips connected together, for example, the second stopper strip 612 is a U-shaped stopper strip, two side strips of the U-shaped stopper strip are connected to the second pull tab 611, and one horizontal strip of the U-shaped stopper strip can be locked or unlocked with respect to the second lifting hook 613.

[0103] Furthermore, the second lifting hook 613 and the fixed base 601 may be independent members, or the second lifting hook 613 and the fixed base 601 may be formed as an integral member.

[0104] Furthermore, in the storage case 24 of the present invention, the lift member 57 may have a fixed length, or the lift member 57 may be adjustable in length, allowing the user or another user to adjust the length of the lift member 57 according to their individual needs. In some embodiments, the lift member 57 includes multiple rod members that are nested in sequence and are extendable, allowing the user to adjust the length of the lift member 57 through the extendable rod members. In some embodiments, the storage case 24 includes multiple lift members 57 with different lengths, each of which is removably and pivotally mounted on the same pivot structure, allowing the user to replace the lift member 57 of the appropriate length according to their needs.

[0105] 43, casters 37 are provided at one end of storage case 24, and lift members 57 are provided at the other end of storage case 24. In another embodiment, casters 37 are provided at opposite end edges of storage case 24, and storage case 24 includes two opposing, spaced-apart lift members 57, allowing a user to operate the lift members 57 from either end. Also, when both lift members 57 are in the raised position, a user can lift storage case 24 by grasping both lift members 57 with both hands, or two users can lift storage case 24 by grasping both lift members 57 at opposite ends.

[0106] In addition, in the storage case of the present invention, the lift member 57 may have multiple types of structure. For example, in one type of structure of the lift member 57, the lift member 57 may be a T-shaped bar, and the vertical bar member of the T-shaped bar may be a fixed bar member or an extendable bar member. The vertical bar member may be pivotally connected to an appropriate position of the storage case 24, for example, it may be installed at the top or end of the upper body 33, or at the bottom or end of the underbody 34, and the horizontal bar member of the T-shaped bar may be a gripping bar member for the user to grip.

[0107] Furthermore, for example, in one type of structure of the lift member 57, the lift member 57 may be an L-shaped bar, and the vertical bar member of the L-shaped bar may be a fixed bar member or an extendable bar member, and the vertical bar member may be pivotally connected to an appropriate position of the storage case 24, for example, installed on the side of the upper body 33 or the underbody 34, and the horizontal bar member of the L-shaped bar may extend to a predetermined length to form a gripping bar member for the user to grip.

[0108] Further, for example, in one type of structure of the lift member 57, referring to FIG. 45, the lift member 57 further includes a side bar 571, one end of which is attached to the side edge of the storage case 24 by a pivot structure 58, thereby allowing the lift member 57 to pivot, wherein the storage case 24 further includes a releasable first stop structure 60 and a releasable second stop structure 61 attached to its side edge, the first stop structure 60 being configured to hold the lift member 57 in a pulled position, and the second stop structure 61 being configured to cooperate with the lift member 57 to allow the lift member 57 to pivot between a raised position and a retracted position.

[0109] 45 , in some embodiments, the second stop structure 61 is arranged at an upward incline so that the lifting stop point 615 of the second stop structure 61 is higher than the retraction stop point 616 and is located between the retraction stop point 616 and the pivot connection point 56. In this manner, the pivot range of the lift member 57 can be expanded, the lift member 57 has a simple structure (e.g., a U-shape, as described below), and when in the raised position, the lift member 57 can be located in the center of the storage case 24, thereby lifting the storage case 24 in a more balanced manner. In some select embodiments, the lifting stop point 615 and the retraction stop point 616 may be aligned in the height direction of the storage case 24.

[0110] In some embodiments, the lift stop point 615 and the retract stop point 616 may be provided as stop posts installed on the storage case 24, and the stop post as the lift stop point 615 is extendable, so that when the stop post is retracted, the lift member 57 can pivot beyond the lift stop point 615, and when the stop post is extended, the lift member 57 is stopped between the two stop posts (i.e., the lift stop point 615 and the retract stop point 616).

[0111] In addition, in some embodiments, as shown in Figures 46 and 48, the lifting stop point 615 and the retracting stop point 616 may be provided as connection points between the second pull tab 611 and the second stop strip 612, and as matching points between the second stop strip 612 and the second lifting hook 613 in the locked state.

[0112] 39 to 48, in some embodiments, the lift member 57 is a U-shaped device, with one end of two side bars 571 of the U-shaped device attached to opposite side edges of the storage case 24 by respective pivot structures 58, and the other ends of the two side bars 571 connected by a gripping bar 570, with a first stop structure 60 and a second stop structure 61 attached to each side edge. In this way, the U-shaped device allows the user to pull and lift the storage case 24 in a more balanced manner.

[0113] In some embodiments, in order to further improve the reliability of the upper body 33 and the underbody 34 after closing, referring to FIG. 27 , a temporary positioning groove 44 extending in the circumferential direction is formed in the peripheral portion of the contact opening of one of the upper body 33 and the underbody 34. For example, the temporary positioning groove 44 extends along the locking side edge 28 and the locking end edge 29 on both sides. A temporary positioning flange 45 extending in the circumferential direction is formed in the peripheral portion of the contact opening of the other of the upper body 33 and the underbody 34. For example, the thickness of the temporary positioning flange 45 is smaller than the thickness of the other wall of the upper body 33 and the underbody 34, thereby forming a stopper step between the temporary positioning flange 45 and the other wall of the upper body 33 and the underbody 34, and the temporary positioning flange 45 is temporarily positioned in the temporary positioning groove 44 so that the shapes match, so that, for example, when the temporary positioning flange 45 extends into the temporary positioning groove 44, the stopper step can come into contact with the edge of the groove opening in the temporary positioning groove 44. In this way, the reliability of the closure of the upper body 33 and the underbody 34 can be further improved.

[0114] In a second aspect, the present invention provides an elastic cushion device, and see Figures 23, 24, 27 and 28. The elastic cushion device includes an elastic cushion 2 and any of the storage cases 24 described in the first aspect above, wherein the elastic cushion 2 is removably assembled, and wherein the elastic cushion 2 is configured so that the elastic cushion member formed by removing the elastic cushion 2 can be stored in the storage space and the storage case 24 can be closed, and when the storage case 24 is opened, the elastic cushion member can be removed from the storage space and assembled as an elastic cushion.

[0115] In this way, after the elastic cushion 2 is removed, each elastic cushion member of the elastic cushion 2 can be placed in the storage space, and the storage case 24 can be closed by the locking structure 25. In this way, the storage case 24 effectively improves the ease of storage of the elastic cushion 2, and at the same time, by carrying the storage case 24, the elastic cushion 2 can be carried to wherever it is needed according to the user's needs, and the space used when storing the elastic cushion 2 can be effectively reduced. When it is necessary to use the elastic cushion 2, the storage case 24 can be opened, and each elastic cushion member can be taken out and then assembled into the elastic cushion.

[0116] 1, 23, 24, 25, and 27, in some embodiments of the elastic cushion device of the present invention, the elastic cushion 2 includes a cushion layer 15 and a plurality of elastic module units 1, each of which includes a fixed bottom plate 3 having a plurality of openings and a plurality of elastic modules 4 installed in the plurality of openings of the fixed bottom plate 3, and each of which has an internal space, and the plurality of elastic modules 4 of one elastic module unit 1 communicate with the internal space of the plurality of elastic modules 4 of another elastic module unit 1 through corresponding openings in the fixed bottom plate 3 of the other elastic module unit 1. 25, the internal space of each elastic module 4 of the lowermost elastic module unit 1 is used as an item storage space 40 for storing additional items. Referring to FIG. 26, the cushioning layer 15 is configured to be folded from an unfolded state into a folding block 41. When unfolded, the cushioning layer 15 can be placed on the elastic modules 4 of the elastic support layer formed by connecting the elastic module units 1 together, and the nesting assembly 39 and the folding block 41 can be placed in the storage space. For example, referring to FIGS. 23 and 24, the folding block 41 can be stacked on the nesting assembly 39, or the nesting assembly 39 can be stacked on the folding block 41.

[0117] 40, 41, and 42, in some embodiments, when nesting assembly 39 is placed in the storage space, a storage gap 59 is formed between nesting assembly 39 and a side wall of the storage space (for example, a side wall in the width direction or a side wall in the length direction if the storage case is a rectangular parallelepiped, or any one of the side walls if the storage case is a cube), and in some embodiments, storage gap 59 is located in the width direction of the storage case and extends in the length direction of the storage case, within which folding block 41 can be inserted into storage gap 59. In this way, nesting assembly 39 and folding block 41 can be positioned relative to each other, improving stability during storage.

[0118] In some embodiments, referring to FIG. 12 , the elastic cushion 2 further includes a cover 22, which is configured to be stored in a folding block 41 by being folded from an unfolded state to a folded state. That is, by folding the cover 22 and the cushion layer 15 and packaging them together in the folding block 41 with the binding belt, each component removed from the elastic cushion can be easily packaged and stored in the storage case 24.

[0119] In some other embodiments, referring to FIG. 28, the folding block 41 is a U-shaped block 42, which surrounds the elastic module portion 43 of the nesting assembly 39 and is then placed within the storage space of the storage case 24.

[0120] In some embodiments, in order to improve the stability of the storage of the elastic cushion 2, a recess (not shown) is formed in the bottom wall of the storage space, and at least the bottom of the nesting assembly 39 is contained and positioned within the recess in the bottom wall of the storage space, and the recess restricts the position of at least the bottom of the nesting assembly 39, further improving the stability of the storage of the elastic cushion 2.

[0121] 1 to 8, in some embodiments, the elastic cushion includes a plurality of elastic module units 1, each of which includes a fixed base plate 3 and a plurality of elastic modules 4 mounted on the fixed base plate 3. The fixed base plate 3 includes connecting sides 5 and end sides 6 mounted opposite each other. Each end side 6 has a plurality of connecting members, each of which includes at least one of a rotating locking member 7 and a connector 8. The rotating locking member 7 is configured to be releasably connected to the connector 8 of an adjacent elastic module unit 1 by swinging back and forth around a pivot axis, and the connector 8 is configured to be releasably connected to the rotating locking member 7 of an adjacent elastic module unit 1. Among these, the plurality of fixed base plates 3 are connected together by the connection between the adjacent rotating locking members 7 and the connector 8, thereby assembling the plurality of elastic module units 1 to the elastic support layer 21.

[0122] Thus, the fixed bottom plate 3 includes end sides 6 arranged opposite each other, each end side 6 having a plurality of connecting members, the connecting members including at least one of a rotating locking member 7 and a connecting member 8, the connecting members including at least one of a rotating locking member 7 and a connecting member 8, the rotating locking member 7 being configured to be releasably connectable with the connecting member 8 of an adjacent elastic module unit 1 by swinging back and forth around the pivot axis, and the connecting member 8 being configured to be releasably connectable with the rotating locking member 7 of an adjacent elastic module unit 1. Thus, when assembling the elastic module units 1 into the elastic cushion 2, the connecting sides 5 of the plurality of fixed bottom plates 3 are connected together in order, and the adjacent fixed bottom plates 3 are connected together by joining both the rotating locking members 7 and the connecting members 8, and in this way, all of the fixed bottom plates 3 are joined together by joining the rotating locking members 7 and the connecting members 8, and thereby the plurality of elastic module units 1 can be assembled into the elastic support layer 21 of the elastic cushion 2. Therefore, the elastic module unit 1 can significantly improve the ease of assembly of the elastic cushion 2, and is convenient for removal and storage, thereby effectively reducing the space required for storing the elastic cushion.

[0123] Incidentally, the elastic module unit 1 of the present invention may have multiple types. For example, in the first type of elastic module unit 1, the end side edges 6 of the fixed bottom plate 3 of some elastic module units 1 have multiple rotating locking devices 7 as first elastic module units, and the end side edges 6 of the fixed bottom plate 3 of other elastic module units 1 have multiple connecting devices 8 as second elastic module units. In this way, the multiple connecting devices 8 of one second elastic module unit can respectively connect to the rotating locking device 7 of the adjacent previous first elastic module unit and the rotating locking device 7 of the adjacent next first elastic module unit. According to this type of configuration, multiple elastic module units 1 can be assembled together.

[0124] Furthermore, for example, in the second type of elastic module unit 1, referring to Figures 1 to 7, a rotary locking device 7 and a connecting device 8 are installed on each end side 6 of the fixed bottom plate 3 of the elastic module unit 1. In this way, the rotary locking device 7 of one elastic module unit 1 is connected to the connecting device 8 of the adjacent previous elastic module unit 1, and the connecting device 8 of one elastic module unit 1 is connected to the rotary locking device 7 of the adjacent next elastic module unit 1. According to this type of configuration, multiple elastic module units 1 can be assembled together.

[0125] The connecting members may be located at any position on the end side 6. For example, in some embodiments, the connecting members may be located at the center of the end side 6, or at other positions close to the center of the end side 6. Furthermore, for example, in some other embodiments, referring to FIG. 6 , a connecting member is located at each corner of each end side 6, so that the corners of the end side 6 can be fully utilized to locate the connecting members, which is convenient for connection to the adjacent fixed bottom plate 3.

[0126] In addition, in the second type of elastic module unit 1 as described above, the end side 6 of the fixed bottom plate 3 of the elastic module unit 1 is provided with a rotary locking member 7 and a connector 8. Therefore, in some embodiments, referring to FIG. 6, the corners of each end side 6 are provided with a rotary locking member 7 and a connector 8, respectively.

[0127] In some embodiments, to facilitate connection between multiple fixed bottom plates 3, the rotating fasteners 7 on the two opposing end sides 6 are located on one diagonal of the elastic module unit 1, while the connectors 8 are located on the other diagonal of the elastic module unit 1, and the rotating fasteners 7 rotate in the same direction. Thus, referring to Figures 6 and 7, any two fixed bottom plates 3 can be connected by rotating the rotating fasteners 7 of any two fixed bottom plates 3 in the same direction.

[0128] Also, in other embodiments, the direction of rotation of the rotary locking device 7 may be different.

[0129] Furthermore, in the elastic module unit 1 of the present invention, the connector 8 may have multiple types of structure. For example, in one type of structure of the connector 8, the connector 8 may be a rotating locking member 7, and thus the rotating locking members 7 of adjacent fixed bottom plates 3 can be connected. Furthermore, in another type of structure of the connector 8, for example, referring to Figures 2, 4, and 7, the connector 8 includes an engaging post 9. In this way, when the rotating locking member 7 is connected to the engaging post 9, the adjacent fixed bottom plates 3 are connected, and when the rotating locking member 7 is released from the engaging post 9, the adjacent fixed bottom plates 3 are separated.

[0130] In addition, in some embodiments, referring to Figures 2, 4 and 6, a receiving groove 10 capable of receiving a connecting member is formed on the circumferential side surface at each corner of the fixed bottom plate 3. In this way, the connecting members, for example, the rotary locking device 7 and the connector 8, are positioned in the corresponding receiving groove 10, thereby preventing most of the connecting members from being exposed from the circumferential side surface of the fixed bottom plate 3.

[0131] 2 and 4, in some embodiments, the receiving groove 10 may have an upper wall 11, i.e., the receiving groove 10 is formed on the circumferential side surface at the corner position of the fixed bottom plate 3, and the upper wall 11 has an operating opening 12 for the user to easily apply force to rotate the rotary locking device 7. In this way, the operator can easily drive the rotary locking device 7 through the operating opening 12 when connecting each fixed bottom plate.

[0132] Also, in some embodiments, referring to FIG. 6, the receiving groove 10 may not have an upper wall 11, that is, a receiving recess is formed at the corner position of the upper surface of the fixed bottom plate 3, and the receiving recess extends outward to the circumferential side surface of the fixed bottom plate as the receiving groove 10, and in this case, the connecting members, such as the rotary locking device 7 and the connecting device 8, can be positioned in the corresponding receiving recesses.

[0133] In addition, the rotating locking device 7 may have a variety of structural forms. For example, in some embodiments, referring to FIGS. 2, 4, and 7, the rotating locking device 7 includes a locking hook 13 and a lifting hook 14, and the locking hook 13 is configured to be releasably engaged with and connected to the connector 8 of the adjacent elastic module unit 1. The rotating locking device 7 has a storage position and a connection position. In the storage position, the lifting hook 14 is located in the receiving groove 10, and a portion of the locking hook 13 extends laterally from the receiving groove 10. In this way, the operator can easily drive and rotate the rotating locking device 7 by operating the locking hook 13 with a part of the locking hook 13, and at the joining position, the locking hook 13 is located within the storage groove of the adjacent elastic module unit, and a part of the lifting hook 14 extends sideways from the storage groove 10 of the adjacent elastic module unit, and in this way, the operator can easily drive and rotate the rotating locking device 7 by operating the lifting hook 14 with a part of the lifting hook 14.

[0134] In some embodiments, referring to FIG. 7 , the rotating fastener 7 is configured to hook onto and connect to a connecting string 16 on the cushion layer 15 of the elastic cushion 2. By hooking onto the connecting string 16 and the rotating fastener 7, the elastic cushion can be formed into an elastic cushion 2 without side end sealing members. Because no side end sealing members are installed, the elastic cushion 2 has good internal structure permeability and good air permeability, improving the air permeability and comfort of the elastic cushion 2. When the elastic cushion 2 needs to be stored, the connecting string 16 and the rotating fastener 7 can be released and the fixed base plates 3 can be detached from each other, allowing for quick removal and storage, which is effective in reducing the space required for transporting and storing the elastic cushion. The connecting string 16 may be a single connecting string, or it may be part of the thread of the mesh-like side end sealing members.

[0135] In some embodiments, the rotating fasteners 7 are configured to releasably hook onto the corresponding connecting strings 16 on the elastic cover 22. By hooking onto the rotating fasteners 7 using the connecting strings 16, the elastic cushion can be formed into an elastic cushion 2 without side end sealing members. Because no side end sealing members are installed, the elastic cushion 2 has good internal structure permeability and good air permeability, improving the air permeability and comfort of the elastic cushion 2. When the elastic cushion 2 needs to be stored, it can be quickly removed and stored by releasing the connecting strings 16 and the rotating fasteners 7 and detaching the fixed base plates 3 from each other, which is effective in reducing the space required for transporting and storing the elastic cushion. The connecting strings 16 may be a single connecting string, or may be part of the mesh threads of the mesh side members.

[0136] Furthermore, multiple types of rotating fasteners 7 may be provided, and any type of rotating fastener 7 may be used as long as it can be hooked onto the connecting string 16. For example, in some embodiments, referring to Fig. 7, the rotating fastener 7 includes a locking hook 13 and a lifting hook 14, and the locking hook 13 is configured to be releasably engaged with and connected to the connector 8 of an adjacent elastic module unit 1, wherein the rotating fastener 7 includes a storage position and a connecting position, and in the storage position, the locking hook 13 can be releasably hooked onto the corresponding connecting string 16; for example, the lifting hook 14 is positioned within the receiving groove 10, and the locking hook 13 is configured to be hooked onto and connected to the connecting string 16; for example, a portion of the locking hook 13 extends laterally from the receiving groove 10 and is connected to the connecting string 16. In the joining position, the lifting hook 14 can be releasably hooked and connected to the corresponding connecting string 16; for example, the locking hook 13 is positioned within the receiving groove of the adjacent elastic module unit, and the lifting hook 14 is configured to be hooked and connected to the connecting string 16; for example, a portion of the lifting hook 14 extends laterally from the receiving groove 10 of the adjacent elastic module unit and is hooked and connected to the connecting string 16.

[0137] In addition, in some embodiments, in order to improve the accuracy and ease of connecting each fixed bottom plate 3, referring to Figures 1, 3, 5 and 6, a temporary positioning structure is formed on each connecting side edge 5, and the temporary positioning structure is configured to be able to be joined to the temporary positioning structure on the connecting side edge 5 of the fixed bottom plate 3 of an adjacent elastic module unit 1. In this way, when connecting multiple elastic module units, the temporary positioning structures of the fixed bottom plates 3 of the adjacent elastic module units are joined to each other to temporarily position each fixed bottom plate 3, and then the rotating locking device 7 and connecting device 8 of the adjacent fixed bottom plate 3 are joined.

[0138] In addition, multiple types of temporary positioning structures may be provided, and any type of temporary positioning structure can be used as long as it can temporarily position adjacent fixed bottom plates 3. For example, in some embodiments, referring to Figures 1 and 3, the temporary positioning structure includes a first temporary positioning structure 17 and a second temporary positioning structure 18 that are spaced apart in the extension direction of the connecting side edge, and the second temporary positioning structure 18 is different from the first temporary positioning structure 17, wherein the first temporary positioning structure 17 is configured to be able to connect with the second temporary positioning structure 18 of an adjacent elastic module unit 1, and the second temporary positioning structure 18 is configured to be able to connect with the first temporary positioning structure 17 of an adjacent elastic module unit 1, so that the connection between the first temporary positioning structure 17 and the second temporary positioning structure 18 of adjacent fixed bottom plates can further improve the balance of the temporary positioning of adjacent fixed bottom plates.

[0139] Also, in some embodiments, the second temporary positioning structure 18 and the first temporary positioning structure 17 are similar.

[0140] 5, in some embodiments, the first temporary positioning structure 17 located on one side of the elastic module unit and the second temporary positioning structure 18 located on the other side are aligned along the horizontal direction of the elastic module unit (i.e., the height direction in FIG. 5, or, if the fixed bottom plate 3 is rectangular, the width direction of the fixed bottom plate 3), and the second temporary positioning structure 18 located on one side of the elastic module unit and the first temporary positioning structure 17 located on the other side are aligned along the horizontal direction of the elastic module unit. In this way, when connecting adjacent fixed bottom plates 3, it is sufficient to align the fixed bottom plates 3 with each other, which further improves the ease of temporary positioning and joining.

[0141] 1, 3 and 5, the first temporary positioning structure 17 and the second temporary positioning structure 18 may each be a joinable hook engagement groove structure. Alternatively, referring to Figures 1, 3 and 5, the first temporary positioning structure 17 is a temporary positioning bump 19, and the second temporary positioning structure 18 is a temporary positioning groove 20. In this way, when joining adjacent fixed bottom plates 3, the fixed bottom plates 3 are aligned with each other, and then the fixed bottom plates 3 are simply pressed to fit the temporary positioning bump 19 into the temporary positioning groove 20, thereby achieving temporary positioning and joining of the adjacent fixed bottom plates 3.

[0142] 1, in some embodiments, the elastic module unit 1 may be a single bar-shaped unit as a whole, for example, the fixed bottom plate 3 of the elastic module unit 1 is a single bar-shaped plate as a whole. In some embodiments, as shown in FIG. 29, the length of the elastic module unit 1 may be variable, that is, the length of the fixed bottom plate 3 of the elastic module unit 1 may be variable, so that the length of the fixed bottom plate 3 of the elastic module unit 1 can be adjusted correspondingly according to the size of the internal space of the storage case. For example, in some embodiments, as shown in FIGS. 29 to 33, the fixed bottom plate 3 of the elastic module unit 1 includes a first plate portion 311 and a second plate portion 312 in its length direction, and a plurality of elastic modules 4 are respectively installed on the first plate portion 311 and the second plate portion 312, of which one side of the opposing ends of the first plate portion 311 and the second plate portion 312 are integrally connected by a hinge structure 313, and the other side of the opposing ends is a releasable hinge. The resilient module units 1 are provided with a connecting structure 314 that can pivot between the first and second plate portions 311, 312. In the first position, as shown in FIG. 29, the connecting structure 314 is not released, thereby connecting the short sides of the first and second plate portions 311, 312 together. When the connecting structure is released, the first and second plate portions 311, 312 can pivot from the first position to the second position. In the second position, as shown in FIG. 31, the long sides of the first and second plate portions 311, 312 are connected together. As shown in FIG. 32, multiple resilient module units 1 in the second position can be nested and stacked in order to form a nested assembly 39, as shown in FIG. 33. As shown in FIG. 34, the nested assembly 39 can be placed directly into a storage case. Alternatively, in another storage configuration, as shown in FIG. 35, multiple resilient module units 1 in the second position can be nested and stacked in order and placed into a storage case.

[0143] Furthermore, the hinge structure 313 and the connecting structure 314 may have multiple types, and any type can be adopted as long as the above-described contents are realized. For example, in one type, the hinge structure 313 is a hinge structure or a pivot assembly including an intermediate connecting plate and a pivot, and the connecting structure 314 is a locking block and a locking groove or a hook-and-loop fastener. For example, the locking block and the locking groove may be formed on the first plate portion 311 and the second plate portion 312. When the locking block is engaged and connected in the locking groove, the first plate portion 311 and the second plate portion 312 are connected at a first position. When the locking block is released from the locking groove, the first plate portion 311 and the second plate portion 312 are separated so as to be pivotable from the first position to the second position around the hinge structure.

[0144] 16 and 17, in some embodiments, the elastic cushion 2 further includes a cover 22, which includes at least one inner core layer 221, an outer wrapping material 222, and a stopper fold 23, wherein the at least one inner core layer 221 includes an elastic material layer, which may be a sponge layer, a silicone gel layer, or any other elastic material layer, and the outer wrapping material 222 can removably cover the at least one inner core layer 221 in any form, and the stopper fold 23 is folded downward from the periphery of the cover 22 along the thickness direction of the elastic cushion 2 and extends a predetermined distance to form an internal space 231 that can accommodate and shield the cushion layer 15 of the elastic cushion 2, and the cover 22 can be folded and stored in the storage space.

[0145] Because at least one inner core layer 221 of the cover 22 includes an elastic material layer, the elastic support function of the cover 22 is effectively improved, and the support function and comfort of the elastic cushion are also further improved. Furthermore, because the outer wrapping material 222 removably covers the at least one inner core layer 221, the outer wrapping material 222 can be removed and washed when necessary for clinic use. Furthermore, the stopper fold 23 extends from the periphery of the cover 22 to form an internal space 231 that can accommodate and shield the cushion layer 15 of the elastic cushion 2 when the elastic cushion 2 is assembled, thereby improving the ease of assembly of the elastic cushion 2 and effectively reducing the space required for storage of the elastic cushion 2.

[0146] In addition, due to the tensile force of the edge connection structure described below, the stopper folded edge 23 is in a downwardly extending tensile state, which allows it to abut and stop the outermost elastic module 4, effectively preventing movement of the outermost elastic module 4 in the lateral direction of the elastic cushion and improving the stability of the elastic module.

[0147] In some embodiments, the stopper fold 23 of the cover 22 may be an independent member and may be connected to the periphery of the outer wrapping material 222 in various ways, such as by stitching, welding, fasteners, snaps, etc.

[0148] Furthermore, in some embodiments, referring to FIG. 16 , the stopper folding edge 23 is formed by a portion of the outer packaging material 222 that extends a predetermined distance while being folded downward from the periphery of the cover 22. In other words, the stopper folding edge 23 and the outer packaging material 222 are integrally molded. In this way, by utilizing the wholeness of the portion of the outer packaging material 222 that covers at least one inner core layer 221, the position of the periphery can be restricted relative to the portion that is folded downward, thereby improving the stability of the stopper folding edge 23.

[0149] 17, in some embodiments, at least one inner core layer 221 is folded downward from the periphery of the cover 22 and extends a predetermined distance to form a folding edge layer 2211, and the outer wrapping material 222 is folded downward from the periphery of the cover 22 and extends a predetermined distance to form a folding edge sleeve 2221, wherein the folding edge sleeve 2221 covers the folding edge layer 2211 to form the stopper folding edge 23. In this way, the folding edge layer 2211 and the folding edge sleeve 2221 covering the folding edge layer 2211 can further improve the strength of the stopper folding edge 23, thereby further improving the reliability of positioning the cushion layer contained in the internal space 231.

[0150] 10, 11, and 13 to 15, in some embodiments, the cover 22 further includes an edge connection structure configured to be connected to the bottom layer of the elastic cushion. After the edge connection structure is connected to the bottom layer of the elastic cushion, the edge connection structure can further pull the stopper fold 23, thereby further improving the stopper effect of the stopper fold 23.

[0151] The edge connection structure may also have multiple types. For example, in some embodiments, the edge connection structure may be a zipper structure, and the assembly member of the zipper structure is disposed between the stopper fold 23 and the bottom layer of the elastic cushion. Furthermore, for example, in other embodiments, the stopper fold 23 and the edge connection structure cooperate to form the elastic cushion 2 without side end sealing members. In this way, since the side end sealing members are not installed, the elastic cushion 2 has good internal structure permeability and good air permeability, improving the air permeability and comfort of the elastic cushion 2.

[0152] The edge connection structure may have multiple structures. However, as long as any structure can connect the bottom layer of the elastic cushion to the cover 22, the elastic cushion does not need to have a side end sealing member. For example, in one edge connection structure, the edge connection structure may be a mesh body, and the multiple meshes of the mesh body can improve the air permeability of the elastic cushion 2. In another edge connection structure, see FIGS. 11 and 14, the edge connection structure includes multiple connecting strings 16 spaced apart along the circumferential direction of the elastic cushion. For example, the connecting strings 16 may be connected to the edge of the cover 22, e.g., the connecting strings 16 are connected to the stopper folded edge 23. In this manner, the connecting strings 16 may be connected to the bottom layer of the elastic cushion (e.g., the fixed bottom plate 3). The connecting strings 16 may be multiple ring-shaped strings that are independent of each other and spaced apart, or they may extend continuously in a wave pattern.

[0153] In some embodiments, all of the stopper folds 23 are connected to the bottom layer of the elastic cushion by an edge connection structure. In other embodiments, referring to Figures 10 and 12, at least two opposing stopper folds 23 of the stopper folds 23 are connected to the bottom layer of the elastic cushion by an edge connection structure, thereby ensuring the reliability of the connection of the cover 22 and effectively simplifying the steps of assembling the elastic cushion, thereby improving the ease of assembly.

[0154] 10 and 13, the stopper fold 23 extends close to the bottom layer of the elastic cushion, maintaining a predetermined distance between it and the bottom layer of the elastic cushion. The length of the stopper fold 23 is set so as to cover at least a part or all of the height of the elastic module 4. In this way, the appearance of the elastic cushion can be effectively improved while ensuring the air permeability of the elastic cushion.

[0155] In some embodiments, cushion layer 15 may be a single cushion layer, such as a single sponge layer or a single silicone gel layer. In another embodiment, referring to FIG. 18 , cushion layer 15 includes multiple internal layers stacked in the thickness direction of the cushion layer and an external cover 151 removably surrounding the multiple internal layers, where the multiple internal layers include an internal elastic layer 152 and an internal soft layer 153. It is preferable that internal elastic layer 152 be located above internal soft layer 153 in the thickness direction of the cushion layer. In this way, internal elastic layer 152 can provide good elastic support while internal soft layer 153 can be in stable and reliable contact with the underlying elastic module, improving durability.

[0156] It should be noted that the elastic support layer 21 may have multiple types. For example, in some embodiments, the elastic support layer 21 may include a one-piece bottom layer and multiple elastic modules 4 installed on the one-piece bottom layer. 1 to 8, for example, in some other embodiments, the elastic cushion includes a plurality of elastic module units 1, each of which includes a fixed base plate 3 and a plurality of elastic modules 4 mounted on the fixed base plate 3. The fixed base plate 3 includes connecting sides 5 and end sides 6 mounted opposite each other. Each end side 6 has a plurality of connecting members, each of which includes at least one of a rotating locking member 7 and a connector 8. The rotating locking member 7 is configured to be releasably connected to the connector 8 of an adjacent elastic module unit 1 by swinging back and forth around a pivot axis, and the connector 8 is configured to be releasably connected to the rotating locking member 7 of an adjacent elastic module unit 1. Among these, the plurality of fixed base plates 3 are connected together by the connection between the adjacent rotating locking members 7 and the connector 8, thereby assembling the plurality of elastic module units 1 to the elastic support layer 21.

[0157] In some embodiments of the elastic cushion device of the present invention, the elastic cushion 2 may be placed directly on the ground, for example, on indoor or outdoor ground, grass, etc. Optionally, in some embodiments, as shown in FIGS. 49, 50, and 56, the elastic cushion device further includes a support frame 70, which is configured to have a flat state and a storage state. In the flat state, the elastic cushion 2 can be placed on the support frame 70, and in the storage state, the support frame 70 can be stored in the storage space and the storage case 24 can be closed. In this way, the user may use the elastic cushion 2 by directly placing it on the ground, or by placing the support frame 70 flat and placing the elastic cushion 2 on the support frame 70, depending on their needs. The support frame 70 not only increases the height of the device but also separates the elastic cushion 2 from the ground, effectively preventing moisture when the ground is humid. After the user has finished using the device, the support frame 70 can be stored and placed in the storage case 24, which is convenient for carrying around, effectively improves ease of use, and reduces the space required for storing the support frame 70.

[0158] Of course, the support frame 70 in the stored state may be placed in any appropriate position in the storage case 24. For example, the support frame 70 may be placed on the bottom of the storage case 24, or may be inserted vertically into a space between the elastic cushion member and the side wall of the storage case 24, such as the storage space 59 shown in FIG. 59 above. Alternatively, the support frame 70 may be placed horizontally on the elastic cushion member.

[0159] 53 to 56 , in some embodiments, multiple elastic module units 1 of the elastic cushion 2 can be nested together in order to form a nesting assembly 39, which can be placed in the storage space with the multiple horizontally spaced elastic modules 4 facing upward, and a support frame 70 in the stored state, which has multiple horizontally spaced through-holes 71, can be placed on the nesting assembly 39 so that each elastic module 4 is housed in a corresponding through-hole 71. In this way, the space around each elastic module 4 can be effectively utilized to store the support frame 70, reducing the additional space used by the support frame 70. At the same time, because the elastic modules 4 are located in the through-holes 71, the position of the elastic modules 4 can be limited relative to the support frame 70, preventing unnecessary significant lateral movement of the support frame 70 within the storage case 24.

[0160] Of course, in the elastic cushion device of the present invention, the support frame 70 may have a plurality of structures, and whichever structure the support frame 70 adopts, it is sufficient that it is placed inside the storage case 24 when it is put into the stored state. For example, in some embodiments, it is sufficient that the support frame 70 has a through space 71 when it is put into the stored state from the flat state.

[0161] The support frame 70 of the present invention includes, but is not limited to, the example shown in Fig. 49. For example, in some embodiments, referring to Figs. 49, 51a, and 52a, the support frame 70 includes a plurality of vertical supports 72 and a plurality of horizontal supports 73 removably assembled together, wherein each vertical support 72 includes a plurality of spaced-apart first through-spaces 721, each configured to accommodate at least one elastic module 4, and each horizontal support 73 includes a plurality of spaced-apart second through-spaces 731, each configured to accommodate at least two elastic modules 4. In this way, when it is necessary to store the support frame 70, the support frame 70 is disassembled into a plurality of vertical supports 72 and a plurality of horizontal supports 73, and the plurality of vertical supports 72 and the plurality of horizontal supports 73 are stacked in order on the nesting assembly 39, thereby storing the elastic module 4 in the first through space 721 and the second through space 731.

[0162] It should be noted that the vertical supports 72 and the horizontal supports 73 include, but are not limited to, the structures shown in Figures 51a and 52a. The vertical supports 72 and the horizontal supports 73 may have other structures. The terms "vertical" and "horizontal" used herein refer only to directions and do not indicate the length of the supports. The vertical supports 72 and the horizontal supports 73 may have a predetermined length. For example, as shown in Figure 52a, the multiple first through-holes 721 in each vertical support 72 may be arranged in a single row along the vertical direction, or in multiple columns along the vertical direction, e.g., both columns. Similarly, the multiple second through-holes 731 in each horizontal support 73 may be arranged in a single row or multiple rows along the horizontal direction, e.g., both columns as shown in Figure 51a.

[0163] Also, in some embodiments, the longitudinal support 72 may be formed of a single member and the lateral support 73 may be formed of a single member.

[0164] In addition, in some embodiments, each vertical support 72 includes a plurality of vertical support sections 722 connected together in sequence along the vertical direction, and the plurality of vertical support sections 722 can be stacked together so that the first through spaces 721 of the plurality of vertical support sections 722 overlap. In this way, the user can easily unfold or overlap the plurality of vertical support sections 722, so that the vertical support 72 can be extended to the required length when unfolded and can reduce storage space when overlapped. And / or, each lateral support 73 includes a plurality of lateral support sections 732 connected together in sequence along the lateral direction, and the plurality of lateral support sections 732 can be stacked together so that the second through spaces 731 of the plurality of lateral support sections 732 overlap; in this way, the user can easily unfold or overlap the plurality of lateral support sections 732, so that the lateral support 73 can be extended to the required length when unfolded and can reduce storage space when overlapped.

[0165] Additionally, in some embodiments, the multiple longitudinal support sections 722 and / or the multiple lateral support sections 732 may be sequentially connected together in multiple removable configurations, such as mating or threaded connections.

[0166] Also, in some embodiments, referring to Figures 52a to 52e, multiple vertical support sections 722 are connected together so that they can rotate sequentially along the vertical direction, and in Figure 52a, when the vertical support device 72 is in an unfolded state and needs to be stored, each vertical support section 722 is folded sequentially in opposite directions, and finally, as shown in Figures 52b to 52d, multiple vertical support sections 722 are stacked together to form a single folding member, and then, as shown in Figure 52e, each folding member can be nested sequentially as an elastic module 4 of the nesting assembly 39. 51a to 51d, the multiple lateral support sections 732 are connected together so as to be sequentially rotatable along the lateral direction. In FIG. 51a, the lateral supports 732 are in an unfolded state. When storage is required, each lateral support 732 is folded in the opposite direction in sequence. Finally, as shown in FIGS. 51b and 51c, the multiple lateral supports 732 are stacked together to form a single folded member. Then, as shown in FIG. 51d, each folded member can be nested in sequence as an elastic module 4 of the nesting assembly 39. This sequential rotation configuration allows the user to easily store and unfold each vertical support 72 and / or each lateral support 73, improving the ease and efficiency of removing the support frame 70. The rotational connection configuration may include multiple configurations, including, but not limited to, a rotational connection via a hinge or a rotational connection via a pin shaft.

[0167] Also, in some embodiments of the support frame 70 of the present invention, each vertical support 72 and each horizontal support 73 may have the same height, and when in use, are spaced apart and connected together in sequence.

[0168] Also, in some embodiments, referring to FIG. 49, the height of each vertical support 72 may be smaller than the height of each horizontal support 73, and in use, the horizontal supports 73 are spaced apart along the vertical direction so as to contact the ground, and the vertical supports 72 are spaced apart along the horizontal direction and inserted into all the horizontal supports 73 to maintain a holding distance from the ground.

[0169] Furthermore, the support frame 70 of the present invention has stopper structures disposed along the circumferential direction on its peripheral edges. When an elastic cushion is placed on the support frame 70, the stopper structures are positioned between the support frame 70 and the stopper structures, restricting the position of the elastic cushion and preventing the elastic cushion from shifting horizontally, thereby improving stability when the elastic cushion is used. The stopper structures may have multiple structures, including, but not limited to, the stopper strip shown in FIG. 49 . For example, in some embodiments, the stopper structure is a stopper edge extending continuously in a ring shape. Alternatively, in some embodiments, the stopper structure is a stopper strip disposed at intervals along the circumferential direction. For example, in FIG. 49 , the tops of both ends of each lateral support 73 are each provided with an upwardly extending stopper strip. When the elastic cushion is placed on the support frame 70, the multiple stopper strips on the spaced opposite sides receive the opposite sides of the stopper elastic cushion and restrict the position of the elastic cushion.

[0170] The elastic cushion 2 may be used for any purpose as needed. For example, the elastic cushion 2 may be used as an outdoor pad or an indoor pad. For example, the elastic cushion 2 may be used as an elastic mattress, sofa cushion, chair cushion, or bench cushion.

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.
