Directional terms and positional terms referred to herein refer to the relative direction, relative position, and not to absolute direction, absolute position, between the various components.

Referring first to fig. 1, the elastic pad in a preferred embodiment of the present invention is a rectangular parallelepiped structure, and hereinafter, the "longitudinal direction", "transverse direction", and "height direction" should be understood as referring to the rectangular parallelepiped structure shown in fig. 1. For example, the track beams in the various preferred embodiments of the present invention extend in a transverse direction and are spaced apart from each other in a longitudinal direction. "left and right sides" of a component refer to the sides of the component in the transverse direction.

Referring to the exploded schematic view of the elastic pad 100 shown in fig. 2, the elastic pad 100 includes a flexible sleeve 110, a plurality of elastic modules 106, an elastic balancing mesh 104, and an elastic buffer layer 103. The flexible sleeve 110 can define a closed receiving space and includes a flexible sleeve top layer 102, a flexible sleeve bottom layer 105, and a flexible sleeve side wall 109 connected between the flexible sleeve bottom layer 105, the flexible sleeve top layer 102. Referring to fig. 2 and 3, a plurality of elastic modules 106 can be arranged in an array on the flexible sheathing base layer 105 installed in the receiving space. And is in a compressed state between the flexible cover top layer 102 and the flexible cover bottom layer 105.

Turning back to fig. 1, the flexible sleeve 110 is configured to be detachable, such as by pulling the flexible sleeve 110 apart by a zipper 101 extending in the direction of extension of the flexible sleeve sidewall 109, thereby enabling a user to install the elastic module 106, the elastic balancing mesh 104, and the elastic cushioning layer 103 within the flexible sleeve 110 and remove and replace the flexible sleeve 110 from the flexible sleeve 110.

The elastic modules 106 are slidably mounted in place by means of rail beams 108 provided on the flexible jacket bottom 105, each rail beam 108 extending in a transverse direction. One specific implementation is shown in fig. 4-9.

Referring to fig. 4, each rail beam 108 is detachably mounted on the flexible jacket bottom 105 by a set of rail beam mounts 107, each set of rail beam mounts 107 being disposed spaced apart from each other along the extension direction of its corresponding rail beam 108. Each set of rail beam mounts 107 is three, disposed at two ends and intermediate positions of rail beam 108, respectively.

The structure of each rail beam mount 107 is shown in fig. 5A. Each rail beam mounting member 107 is provided with a mounting member protruding portion protruding in a direction perpendicular to the extending direction of the rail beam 108 and parallel to the flexible jacket bottom layer 105 at the top thereof, and a recessed portion 1073 recessed in the longitudinal direction is formed below the protruding portion. In other words, each track beam 108 includes an upper structure 1071 and a lower structure 1072, the dimension of the upper structure 1071 in the longitudinal direction being greater than the dimension of the lower structure 1072 in the longitudinal direction, such that the longitudinal ends of the upper structure 1071 form mount protrusions relative to the lower structure 1072. The mounting tab and recess 1073 therebelow are adapted to mate with the rail beam 108.

With continued reference to fig. 5A, the bottom of the mounting tab is provided with an array of fixing bumps 1074, the fixing bumps 1074 being used to ultrasonically weld the mounting tab to the flexible sleeve bottom layer 105.

Schematic views of the rail beam 108 after being slidably mounted in place in a transverse direction relative to the rail beam mount 107 are shown in fig. 6-7B. Referring to fig. 6 to 7B, the bottom of the rail beam 108 is provided with a mounting receiving portion 1081 corresponding to a mounting member protruding portion that can cooperate with the mounting receiving portion 1081 so that the rail beam 108 can slide in its own extending direction with respect to the rail beam mounting member 107 and be mounted in place. The mounting receptacle 1081 also actually forms a catch 1086 that snaps into the recess 1073 of the rail beam mount 107.

The main structure of the rail beam 108 (i.e., the structure for mating with the spring module 106) is also shown in fig. 7A and 7B. Each track beam 108 includes a support wall 1082 extending from a top side to a bottom side of the track beam 108, a top side engagement portion 1083, and a bottom side engagement portion 1085. The top side engaging portions 1083 are connected to the top side of the support wall 1082 and are respectively bent downward to the left and right sides of the support wall 1082, thereby forming two top side receiving portions 1084 opening downward at the top of the rail beam 108; the bottom side engaging portions 1085 are connected to the bottom side of the support wall 1082 and are bent upward toward the left and right sides of the support wall 1082, respectively, so that two bottom side receiving portions 1084 opening upward are formed at the bottom of the rail beam 108.

Correspondingly, referring to fig. 8 and 9, each elastic module 106 includes a conical spring and a spring bracket 106 accommodating and holding the conical spring, both left and right sides of the spring bracket 106 have engagement protrusions 1061, the engagement protrusions 1061 protruding upward from a top surface of a bottom body of the spring bracket 106 and simultaneously protruding downward from a bottom surface of the bottom body of the spring bracket 106, so that the engagement protrusions 1061 can be simultaneously received by the accommodation portions 1084 of the top side and the accommodation portions 1084 of the bottom side of the rail beams 108 of both left and right sides of the elastic module 106. That is, the left and right sides of each rail beam 108 are provided with structures capable of engaging the elastic modules 106 located at the left and right sides thereof, respectively, and enabling the two elastic modules 106 at the both sides of the rail beam 108 to slide along their respective slide rails independently with respect to each other.

Fig. 5B and 5C show examples of other embodiments of alternative ultrasonic welding. Referring to fig. 5B, the rail beam mount may be adhesively bonded to the flexible jacket bottom layer 105, again including a superstructure 1071 and a substructure 1072 formed with recesses 1073. Referring to fig. 5C, the rail beam mount 107 is riveted to the flexible jacket bottom 105 by rivets 1075, with the rail beam mount 107 also provided with mount protrusions and recesses.

Fig. 11A-13 illustrate another alternative embodiment. In this embodiment, the left and right sides of the spring bracket of each elastic module 125 have the fitting protrusions 1251, and the fitting protrusions 1251 protrude upward from the top surface of the body of the spring bracket and simultaneously protrude downward from the bottom surface of the body of the spring bracket, so that the fitting protrusions 1251 can be simultaneously received by the receiving parts 1212 (which are formed with the receiving grooves 123 shown in fig. 11A and 11B) of the top and bottom sides of the rail beams 121 of the left and right sides of the elastic module. The left and right sides of each rail beam 121 are provided with structures capable of engaging the elastic modules 125 located at the left and right sides thereof, respectively, and enabling the two elastic modules at the both sides of the rail beam 121 to slide along their respective slide rails independently with respect to each other.

However, unlike the previous embodiment, the track beam in this embodiment is directly secured to the flexible jacket bottom layer 122 by ultrasonic welding (as shown in fig. 11A), bonding, and riveting (as shown in fig. 11B) with rivets 124. The present embodiment omits the provision of rail beam mounts.

Fig. 14-17 illustrate yet another embodiment. Referring first to fig. 15, each track beam includes a plurality of track beam segments, each track beam segment being connected in turn in the longitudinal direction. Each track beam segment is provided with a forward projection at the front end and a forward recessed groove at the rear end, the projections and grooves of adjacent track beam segments being adapted to each other so as to connect adjacent track beam segments together. For example, for the adjacent rail beams shown in fig. 15, the protrusions 1312a of the front section of the first rail beam 1312 can extend into the forwardly recessed grooves 1311a of the rear end of the second rail beam 1312.

Referring to fig. 17, each track beam includes: a base 131; a pair of connection walls extending upward from left and right sides of the base 131, respectively; a pair of end walls extending from top ends of the pair of walls opposite each other. There is a space between each pair of end walls, wherein the base 131 and the pair of connecting walls, the pair of end walls, respectively, together define a pair of receiving portions 1313 having openings facing each other, the receiving portions 1313 being formed with receiving grooves 1314. Correspondingly, the left side and the right side of the spring bracket of each elastic module are provided with: a downwardly extending connecting leg; fitting protrusions 1321 extending from the connection legs of the left and right sides of the spring bracket toward each other. The receiving grooves 1314 of the pair of receiving parts 1313 of each rail beam can engage the corresponding fitting protrusions 1321 of the elastic module located at the left and right sides of the rail beam, respectively. Preferably, a partition wall 1315 is provided in the middle of two connection walls of the base 131, and the height of the partition wall 131 is smaller than the height of the connection walls.

Further carefully looking at fig. 14, it is known that the connection wall provided on the left side of the base 131 is intermittently provided in the longitudinal direction, the connection wall provided on the right side of the base 131 is intermittently provided in the longitudinal direction, and the connection wall provided on the left side of the base 131 and the connection wall provided on the right side of the base are staggered in the lateral direction.

The removable elastic pad in this embodiment allows the user to disassemble and house the pad by himself. Fig. 18 and 19 are schematic diagrams showing the disassembly and storage process.

Specifically, the elastic buffer 103, the flexible sleeve top layer 102, and the flexible sleeve side panels 109 can all be rolled up for storage. Still further, the track beam or track beam mount is made of flexible plastic to allow the flexible casing bottom layer 105 incorporating a plurality of track beams to be rolled up and stored along a plane perpendicular to the extending direction of the track beams, and after rolled up and stored, the softer track beams will not puncture the flexible casing bottom layer. It can be understood that the track beam and the track beam mounting member are both structures with certain stable shapes, but are not necessarily very hard, and the track beam mounting member can also deform to a certain extent under the action of certain external force.

Referring to fig. 18, after separating the flexible sleeve 110, the elastic buffer layer 103, the elastic module 106, and the balance net 104 of the removable elastic pad with respect to each other, the following steps may be further taken in: stacking the elastic buffer 103 and the balance net 104 and rolling up and storing them together to form a first storage roll 120a; the flexible sleeve top layer 102, the flexible sleeve side panels 109, and the flexible sleeve bottom layer 105 are separated relative to each other (it will be appreciated that zippers are provided between the flexible sleeve top layer 102, the flexible sleeve side panels 109, and between the flexible sleeve side panels 109 and the flexible sleeve bottom layer 105) and stacked and rolled together to form a second storage roll 120b.

Further, each of the elastic modules 106 is configured in a truncated cone structure having an open lower end and a hollow inside, and the plurality of elastic modules 106 are configured to allow a user to remove the respective elastic modules 106 from the rail beam and to sequentially nest the respective elastic modules in a height direction of the elastic modules to form the elastic module receiving set 120c. In the nested state, the lower elastic module 106 of the adjacent elastic modules 106 is inserted upward into the upper elastic module 106 through the lower end opening of the upper elastic module 106.

Further, the user can put the first storage roll 120a, the second storage roll 120b, and the elastic module storage set 120c together in the storage box 120. The storage box 120 corresponding to the size can be sold or presented together with the removable elastic pad to allow the user to disassemble and store the removable elastic pad at home.

Fig. 19 shows an example of another storage method. Referring to fig. 19, after separating the flexible sleeve 110, the elastic buffer layer 103, the elastic module 106, and the balance net 104 of the removable elastic pad with respect to each other, it may be further accommodated in the following steps: the elastic buffer layer 103, the balance net 104 and the flexible sleeve side wall 109 (it will be understood that a pull chain is arranged between the flexible sleeve top layer 102 and the flexible sleeve side wall 109 and between the flexible sleeve side wall 109 and the flexible sleeve bottom layer 105) are stacked and rolled up together to form a first storage roll 120a; the flexible cover top layer 102, the flexible cover bottom layer 105 are stacked and rolled together to form a second storage roll 120b.

Further, each of the elastic modules 106 is configured in a truncated cone structure having an open lower end and a hollow inside, and the plurality of elastic modules 106 are configured to allow a user to remove the respective elastic modules 106 from the rail beam and to sequentially nest the respective elastic modules in a height direction of the elastic modules to form the elastic module receiving set 120c. In the nested state, the lower elastic module 106 of the adjacent elastic modules 106 is inserted upward into the upper elastic module 106 through the lower end opening of the upper elastic module 106.

Further, the user can put the first storage roll 120a, the second storage roll 120b, and the elastic module storage set 120c together in the storage box 120.

The resilient pad shown in fig. 20 and 21 is an alternative to the resilient pad 200 shown in fig. 1 and 2. As can be seen in fig. 20 and 21, the zipper 201 is disposed between the flexible sleeve bottom layer 205 and the flexible sleeve side panels.

With continued reference to fig. 21, the outer contour of each elastic module is configured in the shape of a truncated cone, and the elastic pad 200 further includes an elastic balancing net 204 disposed in the receiving space, wherein openings 2041 corresponding to all the elastic modules are formed in the elastic balancing net 204, the size of the openings 2041 is consistent with the outer diameter of the predetermined height of the elastic modules, and the elastic balancing net 204 is configured to fit all the elastic modules in the respective openings 2041 so as to associate all the elastic modules. Preferably, as shown in fig. 21, the size of the aperture 2041 is consistent with the outer diameter at the top of the elastic module to enable the flexible cover layer 202, the elastic cushioning layer 203, and the elastic balancing mesh 204 to fit sequentially without spacing. The elastic buffer 203 and the elastic balancing net 204 are made of sponge, and the flexible sleeve is a cloth sleeve.

The various implementation details in the foregoing embodiments may be arranged and combined in different manners, and the obtained technical solutions should also be considered as embodiments of the present invention. For example, in one embodiment, the arrangement of the corresponding flexible sleeve, elastic balancing mesh, elastic cushioning layer, etc. of fig. 20, 21 may be applied to the structures shown in fig. 1, 2; in one embodiment, the manner of "disposing a rail beam by a rail beam mount" may be applied to the rail beams shown in fig. 16 to 17.
