For example, connected can refer to a wall-mounted connection, a detachable connection, an integrated connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or an internal communication between two components. The specified meaning of the terms in the present disclosure can be understood by those of skill in the art based on the specified conditions.
Embodiment 1
[0062] Referring to FIGS. 1-7, this embodiment provides elastic units 1, and each of the elastic units 1 comprises an upper spring 11, a corresponding one of connection modules 13, and a lower spring 12 in sequence along a height direction downwardly. The upper spring 11 and the lower spring 12 are pre-compression springs wrapped by flexible sleeves A made of cloth or other flexible materials. To be precise, the upper spring 11 and the lower spring 12 are tapered springs with large end-surface rings tapering down to small end-surface rings. Construction of a base of the upper spring 11 and an upper cover of the lower spring 12 is the same, and each comprises an outer compression ring 101 and an inner fixing ring 102 that form a nested cooperation. The outer compression ring 101 and the inner fixing ring 102 form the nested cooperation to compress and secure a relative position of a corresponding one of the flexible sleeves A.
[0063] Specifically, referring to FIG. 6, the inner fixing ring 102, disposed inside the corresponding one of the flexible sleeves A, comprises an outer ring wall 1021 and an inner ring 1022 extending inward from the outer ring wall 1021. The outer compression ring 101, disposed outside the corresponding one of the flexible sleeves A, comprises an inner ring wall 1011 and an outer ring 1012 extending from the inner ring wall 1011. The inner ring 1022 of the inner fixing ring 102 abuts the inner ring wall 1011 of the outer compression ring 101, and the outer ring 1012 of the outer compression ring 101 abuts the outer ring wall 1021 of the inner fixing ring 102. That is, both of the base of the upper spring 11 and the upper cover of the lower spring 12 surround and are nested to openings of the flexible sleeves A to form enclosed spaces surrounding the tapered springs. Within each of the enclosed spaces, a corresponding one of the tapered springs is detachably mounted in a fastening groove 103 on the inner fixing ring 102 of a corresponding one of the base of the upper spring 11 and the upper cover of the lower spring 12 by a corresponding one of the small end-surface rings of the tapered springs, and a corresponding one of the large end-surface rings of the tapered springs extends in a direction away from the inner fixing ring 102. With this internal arrangement, the inner fixing ring 102 and the outer compression ring 101 that are nested together are not only stressed as an integrated structure and used as a positioning support, but the user can also adjust a firmness of the elastic pad by replacing pre-compression springs with different tension levels using the fastening groove 103 as a detachable connection structure. Alternatively, in a case where an elastic relaxation of a wire of one of the pre-compression springs occurs after a long time due to crush fatigue, the wire of the one of the pre-compression springs can be replaced by a wire of a new pre-compression spring using the detachable connection structure to solve waste of resources caused by discarding an entirety of the traditional one-piece elastic structural pad due to no targeted maintenance for some aging parts of the traditional one-piece elastic structural pad, so as to improve practicality and durability of a product. Each of the large end-surface rings of the pre-compression springs extends in a direction away from the inner fixing ring 102 to abut and expand a corresponding one of the flexible sleeves A using a predetermined initial compression force. The flexible sleeves A undergo passive stress, and flexible materials of main bodies of the flexible sleeves A are expanded to be stretched at the same time. This enables the flexible sleeves A and the pre-compression springs that are nested together to be more tightly fitted together to ensure that elastic coils spirally disposed on the tapered springs at intervals are integrated along radial slopes, and the torsional deformation resistance of the corresponding one of elastic units 1 is further improved.
[0064] Both of the upper spring 11 and the lower spring 12 are detachably connected to the corresponding one of the connection modules 13 on a middle position of the corresponding one of the elastic units 1 through rotational position-limiting structures and combine to form the corresponding one of the elastic units 1 extending along its own height direction. Specifically, the upper spring 11 and the lower spring 12 are respectively connected to second connection portions on top and bottom surfaces of the corresponding one of the connection modules 13 through first connection portions on the base of the upper spring 11 and the upper cover of the lower spring 12 to obtain a detachable connection. Constructively, the first connection portions are buckles 104, and the second connection portions are buckling grooves 1310 that cooperate with the buckles 104. The buckles 104 are rotatably locked to the buckling grooves 1310 to enable the corresponding one of the elastic units 1 to be assembled.
[0065] Referring to FIG. 5, each of the bucking grooves 131 forms position-limiting structure. The position-limiting structure comprises a first portion 1311 configured to enable a corresponding one of the buckles 104 to be inserted into the first portion 1311 and a second portion 1312 in communication with the first portion 1311 and extending in a circumferential direction of each of the buckling grooves 1310. When each of the buckles 104 moves into the second portion 1312 within a corresponding one of the buckling grooves 1310, each of the buckles 104 forms a positioning fit with the second portion 1312 opposite to an insertion direction of the corresponding one of the buckles 104. The position-limiting structure of each of the buckling grooves 1310 is designed to facilitate quick disassembly or assembly between the upper spring or the lower spring and the corresponding one of the connection modules 13 by the user by rotational twisting.
[0066] Adjacent ones of the elastic units 1 are in the same plane and are connected through third connection portions 132 surrounding peripheries of the connection modules 13. Insertion members 1321 are disposed on first sides of the third connection portions 132, and second sides of the third connection portions 132 comprise grooves 1322. Elastic arms 13211 extending outward to the grooves 1322 are disposed on first ends of the insertion members 1321. When one of the insertion members 1321 on a first one of the elastic units 1 is inserted into a corresponding one of the grooves 1322 of the third connection portions 132 on a second one of the elastic units 1, the one of the insertion members 1321 on the first one of the elastic units 1 elastically abuts a corresponding one of the elastic arms 13211 on the second one of the elastic units 1 and tightly fits a wall of the corresponding one of the grooves 1322 on the second one of the elastic units 1. Second ends of the insertion members 1321 pass through notches of ends of the third connection portions 132 to form operating portions 13212. As position-limiting portions 13221 are disposed on the walls of the grooves 1322, the position-limiting portions 13221 are positioned to and cooperate with protrusion blocks 13213 of the operating portions 13212, and the protrusion blocks 13213 rotate from first positions to second positions under an external force applied to the operating portions 13212. When each of the protrusion blocks 13213 is at a corresponding one of the first portions, two corresponding adjacent ones of the third connection portions 132 that are connected oppositely cooperate by buckling. When each of the protrusion blocks 13213 is at a corresponding one of the second positions, the two corresponding adjacent ones of the third connection portions 132 that are connected oppositely are released from buckling.
[0067] Each of the elastic units 1 comprises the upper spring 11, the corresponding one of the connection modules 13, and the lower spring 12 in sequence along the height direction downwardly. Each of the elastic units 1 that has been assembled is shown in FIG. 1, and a top and a bottom of each of the elastic units 1 are the large end-surface rings of the tapered springs. This structural configuration effectively improves a stressed area and a support area, and an installation balance and an assembly stability of the elastic unit 1 are further enhanced. Considering different requirements of the user on a thickness of the elastic pad, heights of the upper spring 11 and the lower spring 12 connected by the corresponding one of the connection modules 13 in this embodiment are not limited. That is, the heights of the upper spring 11 and the lower spring 12 can be equal or unequal, and the user can selectively configure heights or a number of layers according to his own usage habits. In other words, the user can merely selectively configure the upper spring 11 used as the elastic pad in a single-layer, can selectively configure both of the upper spring 11 and the lower spring 12 in upper and lower layers used as the elastic pad in a double layer, and/or can adjust a thickness and a comfort level of a body of the elastic pad by selecting tension levers of the upper spring 11 and the lower spring 12 in the upper and lower layers.
Embodiment 2
[0068] Referring to FIGS. 8 and 9, this embodiment provides an elastic module formed by combining and assembling the elastic units 1. An inner side of the elastic module comprises multiple of the elastic units 1, and adjacent ones of the elastic units 1 are connected by the third connection portions 132 disposed on the peripheries of the connection modules 13 for a locked connection. When the elastic module is assembled, the elastic units 1 to be installed are firstly placed flat; the elastic units 1 in adjacent positions are then adjusted and aligned according to a placement direction of the third connection portions 132; preset squeezing forces are then applied in opposite directions to two adjacent ones of the elastic units 1 with the positions already adjusted to push two of the insertion members 1321 on the two adjacent ones of the elastic units 1 into two of the grooves 1322 on the two adjacent ones of the elastic units 1, and the two adjacent ones of the elastic units 1 are connected in opposite directions. At this time, two of the operating portions 13212 extend outward. An assembly of the two adjacent ones of the elastic units 1 that are connected in opposite directions is complete by then, subsequent installation steps of remaining ones of the elastic units 1 are completed using the same operation action, and the remaining ones of the elastic units 1 are connected in opposite directions. When the assembled elastic modules are to be disassembled, merely the two of the operation portions 13212 that are symmetrically disposed are pressed at the same time, and a squeezing force from pressing causes the insertion members 1321 to misalign along slope directions, so as to drive the protrusion blocks 13213 disposed on the operation portions 13212 to be separated from a position limitation of the position-limiting portions 13221, and a disassembly of the two adjacent ones of the elastic units 1 that are connected in opposite directions is complete. This assembly method is flexible and convenient, and a geometric shape of the elastic module can be flexibly adjusted according to actual use requirements of the user, so as to overcome the limitation that the existing elastic pad (the existing mattress) can merely be customized or directionally procured according to a size of a main frame of a bed frame, and the common problem that a size and a model of the elastic pad of the traditional one-piece elastic structural pad have poor universality.
Embodiment 3
[0069] Referring to FIGS. 10 and 11, this embodiment provides the elastic pad and furniture configured with the elastic pad. The elastic pad comprises an additional surface layer 2, and the elastic module formed by a spliced assembly of the elastic units 1 in Embodiments 1 and 2. The additional surface layer 2 can be laid on and covers the elastic module formed by the elastic units 1. As corresponding ones of the elastic units 1 on an upper part of the elastic module define inverted tapered shapes, multiple of the inverted tapered shapes that are assembled together are prone to topple and bend when being subjected to stress. This embodiment brings stressed surfaces of the corresponding ones of the elastic units 1 on the upper part of the elastic module together by including the additional surface layer 2 to solve an overall stressed problem of the structure, thus effectively improving denseness and compactness of the overall structure.
[0070] Flexible straps 201 are disposed on a periphery of the additional surface layer 2 at intervals. First ends of the flexible straps 201 are fixedly connected to the additional surface layer 2, and second ends of the flexible straps 201 are connected to insertion buckling seats 202. The insertion buckling seats 202 can be connected to the third connection portions 132 on a periphery of the elastic module to fix the additional surface layer 2 to a top of the elastic module.
Embodiment 4
[0071] Referring to FIGS. 12-15, this embodiment mainly differs from Embodiment 1 in that the third connection portions 132 described in this embodiment comprise first connection structures and second connection structures, and the first connection structures and the second connection structures are alternatively disposed on adjacent side surfaces of the third connection portions 132. The first connection structures and the second connection structures are disposed adjacent to each other on different side surfaces around each of the connection modules 13. More specifically, in this embodiment, insertion members 111 used as the first connection structures are disposed on two first opposing side surfaces of the different side surfaces of a corresponding one of the connection modules 13, and two second opposing side surfaces of the different side surfaces of the corresponding one of the connection modules 13 comprise sockets 112 used as the second connection structures. Protrusion blocks 1111 are disposed on upper sides of the insertion members 111 and used as buckling structures, and upper walls of the sockets 112 comprise spaces into which the protrusion blocks 1111 are buckled. When the insertion members 111 are inserted into the sockets 112, the protrusion blocks 1111 are buckled into the spaces. At this time, positioning fit of the insertion members 111 and the sockets 112 enables the elastic units 1 to be connected. The protrusion blocks 1111 used as the buckling structures have elasticities, and positions of the upper walls of the sockets 112 corresponding to the protrusion blocks 1111 are disposed with release members 1121 configured to push the elasticities of the protrusion blocks 1111. The release members 1121 are pressed to drive the protrusion blocks 1111 to be separated from the spaces of the upper walls of the sockets 112 to release the positioning fit of the insertion members 111 and the sockets 112 to achieve a disassembly of the elastic module. When the elastic module is assembled, one of the insertion members 111 on a first one of the connection modules 13 of the elastic units 1 is inserted into a corresponding one of the sockets 112 on a second one of the connection modules 13 of the elastic units 1, and a corresponding one of the protrusion blocks 1111 is buckled into a corresponding one of the spaces of the upper walls of the sockets 112 to enable the elastic units 1 to be connected. When the elastic module is disassembled, one of the release members 1121 is pressed to drive a corresponding one of the protrusion blocks 1111 to be separated from a corresponding one of the spaces of the upper walls of the sockets 112, and the positioning fit of the sockets 112 and the insertion members 111 is released to disassemble the elastic units 1.
Embodiment 5
[0072] Referring to FIGS. 16-19, this embodiment mainly differs from Embodiment 1 in that the insertion members 121 are inserted into the sockets 122 from an upper side, i.e., from a height direction of the elastic units 1. The sockets 122 comprise openings in an insertion direction of the insertion members 121 and also comprise openings in a direction opposite to the elastic units 1, so that the sockets 122 are more elastic to enable fits between the insertion members 121 and the sockets 122 to be more compact. The insertion members 121 and the sockets 122 are detachably disposed on peripheries of the connection modules 13. Protrusion blocks 1211 used as buckling structures are disposed on two sides or a single side of the insertion members 121, and release members 1221 are disposed on positions of two side walls of the sockets 122 corresponding to the protrusion blocks 1211. The release members 1221 and the two side walls of the sockets 122 form spaces in which the protrusion blocks 1211 are buckled. The insertion members 121 are inserted into the sockets 122 from a vertical direction, and the protrusion blocks 1211 are buckled into the spaces on the two side walls of the sockets 122. At this time, the insertion members 121 are positioned to and cooperate with the sockets 122 to enable the elastic units 1 to be connected. The release members 1221 are pressed to push the protrusion blocks 1211 to be separated from the spaces on the two side walls of the sockets 122 to disassemble two of the elastic units 1.
Embodiment 6
[0073] Referring to FIG. 20, this embodiment mainly differs from Embodiment 1 in that T-shaped protrusions 131 of insertion members used as first connection structures are disposed on two first opposite sides on peripheries of the connection modules 13, and two second opposite sides on the peripheries of the connection modules 13 comprise concave holes of sockets. Push buttons 1320 are sleeved over the concave holes and are configured to move up and down in a vertical direction and be locked to the T-shaped protrusions 131, and a combination of the concave holes and the push buttons 1320 are used as second connection structures. Specifically, the push buttons 1320 comprise buckling holes 13210 corresponding to the concave holes, and position-limiting holes 13220 having diameters smaller than that of the buckling holes 13210 are disposed on upper sides of the buckling holes 13210. When the elastic units 1 are connected, one of the T-shaped protrusions 131 of the connection modules 13 on a first one of the elastic units 1 is inserted into a corresponding one of the concave holes of the connection modules 13 on a second one of the elastic units 1 after passing through a corresponding one of the buckling holes 13210 of the push buttons 1320 on the second one of the elastic units 1. In this state, the T-shaped protrusions 131 pass through both of the concave holes of the sockets and the buckling holes 13210 of the push buttons 1320, and the push buttons 1320 are then pressed downward until the T-shaped protrusions 131 are locked by the position-limiting holes 13220 to enable the elastic units 1 to be connected each other. When the elastic module is disassembled, the push buttons 1320 are lifted upward to enable the buckling holes 13210 to be aligned with the concave holes to be unlocked, and a connection between the elastic units 1 is released by removing the T-shaped protrusions 131 from the concave holes.
Embodiment 7
[0074] Referring to FIGS. 21-23, this embodiment mainly differs from Embodiment 1 in that T-shaped protrusions 141 of insertion members used as first connection structures are disposed on two first opposite sides on peripheries of the connection modules 13, and two second opposite sides on the peripheries of the connection modules 13 comprise grooves 142 and knobs 1421 of sockets. The knobs 1421 are sleeved over the grooves 142, and the knobs 1421 and the grooves 142 combine to be used as second connection structures. The knobs 1421 comprise spaces through which the T-shaped protrusions 141 are buckled into the grooves 142. When the elastic units 1 are connected, one of the T-shaped protrusions 141 on a first one of the elastic units 1 is buckled into a corresponding one of the grooves 142 on a second one of the elastic units 1 through a corresponding one of the knobs 1421 on the second one of the elastic units 1. At this time, the T-shaped protrusions 141 are positioned to and cooperate with the grooves 142 in a horizontal direction. The knobs 1421 rotate until the T-shaped protrusions 141 are positioned to and cooperate with the knobs 1421 in a vertical direction. At this time, the T-shaped protrusions 141 are locked by the knobs 1421 to achieve a connection between adjacent ones of the elastic units 1. When the elastic module is disassembled, the knobs 1421 rotate until the T-shaped protrusions 141 are unlocked by the knobs 1421, and the T-shaped protrusions 141 are taken out to release the connection between the adjacent ones of the elastic units 1.
Embodiment 8
[0075] Referring to FIGS. 24-26, this embodiment mainly differs from Embodiment 1 in that the third connection portions disposed on peripheries of the connection modules 13 comprise first connection structures 152 and second connection structures 151, and the first connection structures 152 and the second connection structures 151 are respectively disposed on different ones of the elastic units 1. In detail, peripheries of the second connection structures 151 comprise connection seats extending outwardly to form first extension portions, and concave holes 1511 used as sockets are disposed on the extension portions. Peripheries of the first connection structures 152 also extend outwardly to form second extension portions, and rotatable protrusions 1521 used as insertion members are disposed on the second extension portions. When the elastic units 1 are connected, the rotatable protrusions 1521 of the first connection structures 152 are inserted into the concave holes 1511 of the second connection structures, and the rotatable protrusions 1521 are positioned to and cooperate with the concave holes 1511 in a horizontal direction. The rotatable protrusions 1521 rotate to be misaligned with the concave holes 1511, and the rotatable protrusions 1521 are positioned to and cooperate with the concave holes 1511 in a vertical direction, so as to achieve a connection between the elastic units 1. When the elastic module is disassembled, the rotatable protrusions 1521 rotate to be aligned with the concave holes 1511, and the rotatable protrusions 1521 can be disengaged from the concave holes 1511 to release the connection between the elastic units 1 at this time.
