FIELD OF THE DISCLOSURE

The present disclosure relates to a connection structure of a pre-compressed spring and an elastic module connected by the connection structure.

BACKGROUND OF THE DISCLOSURE

The existing elastic mattresses made of springs present integral elasticity. Surrounding springs are also pressed accordingly when a local area is pressed, thus the elastic mattress can withstand larger pressure. However, elasticity of the elastic mattress cannot vary as a body posture of a human body varies when used as a spring bed due to assembly structures of springs in the elastic mattress. The springs provide elasticity individually, and upper ends of the springs in the mattress are often connected together. Thus the springs are subjected to integral force. Therefore, it is crucial to allow the springs to be subjected to force independently without separating from each other, so that the elastic mattress can be synchronously deformed in accordance with the posture of the human body.

Embodiment 1

As shown in FIGS. 1 and 2 , each of pre-compressed springs 1 comprises a spring 1.1 and a cloth sleeve 1.2. The spring 1.1 is wrapped by the cloth sleeve 1.2. After the spring 1.1 is loaded into the cloth sleeve 1.2, an end of the cloth sleeve 1.2 is pinched and knotted to obtain a knot top 1.3, and the knot top 1.3 is inserted into a necking ring of the spring 1.1 or a top cover hole. A connector 200 comprises a connecting base 2, front-convex buckles 3, and rear-concave buckles 4. The connecting base 2 is disposed on a waist of each of the pre-compressed springs 1. At least two opposite sides of the connecting base 2 comprise slots 2.1. The front-convex buckles 3 are fixed to front ends of the slots 2.1, and the rear-concave buckles 4 are fixed to rear ends of the slots 2.1. Each of the front-convex buckles 3 has two clamping tongues 3.1 that are separated, and a first one of the two clamping tongues 3.1 is hollow. One side wall of the first one of the two clamping tongues 3.1 is a cantilever 3.2, and the first one of the two clamping tongues 3.1 comprises a clamping structure 3.3.

A connection between the pre-compressed springs 1 is shown in FIGS. 3-5 . The connector 200 is disposed on the waist of each of the pre-compressed springs 1. The pre-compressed springs 1 in a front row and in a rear row are alternatively disposed. The front-convex buckles 3 of the connectors 200 of the pre-compressed springs 1 in the rear row are inserted into the clamping holes 4.1 of the rear-concave buckles 4 of the pre-compressed springs 1 in the front row, thereby connecting the pre-compressed springs 1 in the front row and the rear row together. The connection between the pre-compressed springs 1 can be detached by separating the front-convex buckles 3 from the rear-concave buckles 4 by pressing the platforms 3.4 of the front-convex buckles 3.
Three instances of the connecting base 2, the front-convex buckles 3, and the rear-concave buckles 4 in the connector 200 can be integrated or formed by connecting separate parts. The advantages of the separate parts are that different materials and different strengths can be selected.

Embodiment 2

As shown in FIGS. 6-8 , the pre-compressed springs 1 in Embodiment 2 are the same as that in Embodiment 1. The connector 200 comprises a connecting base 2, protrusions 5, and grooves 6. The connecting base 2 is a quadrilateral connecting base, and two protrusions 5 are fixed to two first corners of the quadrilateral connecting base adjacent to each other. Two grooves 6 are fixed at two second corners of the quadrilateral connecting base.
A connection between the pre-compressed springs 1 is shown in FIG. 8 . The connector 200 is disposed on the waist of each of the pre-compressed springs 1. The pre-compressed springs 1 in the front row and the rear row are alternatively disposed. The protrusions 5 of the connectors 200 of the pre-compressed springs 1 in the rear row are inserted into the grooves 6 of the pre-compressed springs 1 in the front row, thereby connecting the pre-compressed springs 1 in the front row and the rear row together. The connectors 200 can be connected to have the same horizontal height by setting the protrusions 5 and the grooves 6 at different heights. In this embodiment, the protrusions 5 are T-shaped protrusions 5, and the grooves 6 are in-line. The T-shaped protrusions 5 are inserted into the grooves 6 from an upper side without buckle structures, thus achieving stable connection using gravity.

Embodiment 3

As shown in FIGS. 9-11 , the pre-compressed springs 1 of Embodiment 3 are the same as that of Embodiment 1. The connector 200 comprises a connecting base 2 and buckles 8. The connecting base 2 is disposed on the waist of each of the pre-compressed springs 1, and at least two opposite sides of the connecting base 2 comprise slots 2.1. The buckles 8 are fixed to front ends of inner sides of the slots 2.1 of the connecting base 2, and upper and lower clamping tongues 8.1 are disposed on front ends of the buckles 8. The upper and lower clamping tongues 8.1 have elasticities. Rear ends of the buckles 8 can have clamping holes 8.2. Alternatively, the buckles 8 are fixed to the inner sides of the slots 2.1, and the rear ends of the slots 2.1 of the connector 200 define spaces configured for insertion of the upper and lower clamping tongues 8.1.
A connection between pre-compressed springs 1 is shown in FIG. 11 . The connector 200 is disposed on the waist of each of the pre-compressed springs 1, and the pre-compressed springs 1 in the front row and the rear row are alternatively disposed. The buckles 8 of the connectors 200 of the pre-compressed springs 1 in the rear row are inserted into the slots 2.1 of the connecting bases 2 or the rear clamping holes 8.2 of the buckles 8 of the pre-compressed springs 1 in the front row, thereby connecting the pre-compressed springs 1 in the front row and the rear row together.

Embodiment 4

As shown in FIG. 12 , the features of this embodiment are that the pre-compressed springs 1 are connected by two upper and lower connectors 10, which are suitable for springs with greater heights. For example, the heights of the pre-compressed springs 1 are greater than 30 cm.

Embodiment 5

As shown in FIGS. 13-15 , the connector 10 of this embodiment connects multiple of the pre-compressed springs 1 together. The connector 10 comprises two flaps 10.1 and 10.2 or three or four flaps. The multiple of the pre-compressed springs 1 are buckled at corresponding positions of the connector 10 to connect waists of the multiple of the pre-compressed springs together. The connector 10 can be irregularly shaped.

Embodiment 6

As shown in FIGS. 16-18 , the connector 10 of this embodiment connects multiple of the pre-compressed springs 1 together. The connector 10 comprises two flaps 10.1 and 10.2, and the pre-compressed springs 1 are buckled at corresponding positions of the connector 10 to connect waists of the multiple of the pre-compressed springs together. An arrangement of the pre-compressed springs is aligned.

Embodiment 7

As shown in FIGS. 19-22 , the pre-compressed springs 1 of this embodiment are the same as that of Embodiment 1. The connector 200 comprises a connecting base 2, and connection structures 11 with identical structures are disposed on four side surfaces of the connecting base 2. Each of the connection structures 11 comprises a receiving mechanism and a plug-in mechanism. In each of the connection structures 11, the plug-in mechanism is a protrusion 11.1, and the receiving mechanism is a groove 11.2. The protrusion 11.1 in a plane perpendicular to an insertion direction has elasticity, and a release member 11.5 for pushing the elastic member is disposed on a wall of the groove 11.2 of the receiving mechanism, so that the protrusion 11.1 is locked to and is released from the groove 11.2 of the receiving mechanism.
More specifically, the groove 11.2 is disposed on the same side as the protrusion 11.1. One side of the protrusion 11.1 is a cantilever 11.3, and a front end of the cantilever 11.3 comprises a notch used as a clamping structure 11.4. A release member 11.5 is disposed on an end of a wall of the groove 11.2 buckled to the cantilever 11.3, and a bump for buckling to the clamping structure 11.4 is disposed on the wall of the groove 11.2. A position-limiting fit of the clamping structure 11.4 and the bump on the groove 11.2 connect the pre-compressed springs 1 together. The release member 11.5 is pressed to drive the clamping structure 11.4 of the cantilever 11.3 to release from the position-limiting fit with the bump, thereby disassembling the pre-compressed springs 1. The connection structures 11 of the connecting base 2 of this embodiment are completely identical. One of the connection structures 11 of the connector 200 on a first one of the pre-compressed springs 1 can be connected to one of the connection structures 11 on any side of the connector 200 on a second one of the pre-compressed springs 1 by opposite insertion without needing to confirm an insertion direction.

Embodiment 8

As shown in FIGS. 23-26 , this embodiment mainly differs from Embodiment 7 in that the release member 12.5 is connected to the cantilever 12.3 on one side of the protrusion 11.1, the clamping structure 12.4 is a bump on the cantilever 12.3, and a space for buckling to the clamping structure 12.4 is disposed on the groove 12.2. The rest of the pre-compressed springs 1 are the same as in Embodiment 7 and will not be described herein.

Embodiment 9

As shown in FIGS. 27-31 , the pre-compressed springs 1 of this embodiment are the same as that of Embodiment 1. The connector 200 comprises a connecting base 2 and insertion buckles 13. Clamping tongues 13.1 are disposed on front ends of the insertion buckles 13, and rear ends of the insertion buckles 13 comprise clamping holes 13.2. The clamping tongues 13.1 comprise cantilevers 13.3, and release members 13.5 are disposed on the cantilevers 13.3. Clamping structures 13.4 forming position-limiting fit with the clamping holes 13.2 are disposed on the clamping tongues 13.1. Four side surfaces of the connecting base 2 comprise slots 14, and the insertion buckles 13 are inserted into the slots 14 on two opposite sides of the connecting base 2. After the insertion buckles 13 are inserted into the slots 14, the clamping tongues 13.1 extend out of front ends of the slots 14, and the clamping holes 13.2 are disposed on rear ends of the slots 14.
In this embodiment, the insertion buckles 13 are fixed to the two opposite sides of the connecting base 2 by the slots 14. When the pre-compressed springs 1 are connected, the pre-compressed springs 1 in the front row and the rear row are alternatively disposed, and the clamping tongues 13.1 of the connectors 200 of the pre-compressed springs 1 in the rear row are plugged into the clamping holes 13.2 of the pre-compressed springs 1 in the front row to connect the pre-compressed springs 1 in the front row and the rear row together. After the connection is complete, the slots 14 of another two sides of each row of the pre-compressed springs 1 in which no insertion buckles 13 are inserted just abut each other. When the pre-compressed springs 1 are disassembled, the release members 13.5 are pressed to drive the clamping structures 13.4 on the clamping tongues 13.1 to release the position-limiting fit with the clamping holes 13.2, thereby disassembling the pre-compressed springs 1 in the front row and the rear row.
In this embodiment, for aesthetics and further securing the pre-compressed springs 1 in outermost rows, each of edge connectors 15 is inserted into two slots 14 that abut each other in the outermost rows to further secure the pre-compressed springs 1 in the outermost rows.

Embodiment 10

As shown in FIGS. 32-35 , the pre-compressed springs 1 of this embodiment are the same as that of Embodiment 1. The connector 200 comprises a connecting base 2, and a protrusion 16 as an insertion member and a groove 17 as a socket are respectively disposed on two opposite sides of the connecting base 2. A protrusion 16 and a groove 17 are also respectively disposed on another two opposite sides of the connecting base 2. An upper side of the protrusion 16 comprises a bump 16.1 used as a clamping structure, and a space into which the bump 16.1 is buckled is disposed on an upper wall of the groove 17. When the bump 16.1 is buckled into the space, a position-limiting fit of the protrusion 16 and the groove 17 is achieved.
The bump 16.1 has elasticity, and a release member 17.1 for pushing the bump 16.1 is disposed on a position of the upper wall of the groove 17 corresponding to the bump 16.1. The release member 17.1 is pressed to drive the bump 16.1 to leave the space on the upper wall of the groove 17, thus releasing the position-limiting fit between the protrusion 16 and the groove 17.
When the pre-compressed springs 1 are connected, the protrusion 16 of the connector 200 on a first one of the pre-compressed springs 1 is inserted into the groove 17 of a second one of the pre-compressed springs 1, and the bump 16.1 is buckled into the space on the upper wall of the groove 17 to connect the pre-compressed springs 1 together. When the pre-compressed springs 1 are disassembled, the release member 17.1 is pressed to drive the bump 16.1 to leave the space on the upper wall of the groove 17 to release the position-limiting fit between the protrusion 16 and the groove 17, thus disassembling the pre-compressed springs 1.

Embodiment 11

As shown in FIGS. 36-40 , this embodiment mainly differs from Embodiment 10 in that the connector 200 comprises four detachable flaps 18.1, 18.2, 18.3, and 18.4. The four detachable flaps 18.1, 18.2, 18.3, and 18.4 are buckled to each other and buckled to a waist of a pre-compressed spring 1. After buckling together, protrusions 16 are disposed on two opposite sides of a connecting base 2, and another two opposite sides of the connecting base 2 comprise grooves 17. The rest of the pre-compressed springs 1 are the same as in Embodiment 10 and will not be described herein.

Embodiment 12

As shown in FIGS. 41-44 , this embodiment mainly differs from Embodiment 10 in that protrusions 19 and grooves 20 are detachably connected to the connecting base 2. A connector 200 is divided into two flaps 21.1 and 21.2, and the two flaps 21.1 and 21.2 are connected by buckling via the protrusions 19 and buckled to a waist of each of the pre-compressed springs 1. After buckling together, the protrusions 19 are disposed on the two opposite sides of the connecting base 2, and another two opposite sides of the connecting base 2 comprise the grooves 20. Two sides of each of the protrusions 19 comprise bumps 19.1 used as clamping structures, and release members 20.1 are disposed at positions of two side walls of a corresponding one of the grooves 20 corresponding to the bumps 19.1. The release members 20.1 and the two side walls of the corresponding one of the grooves 20 form spaces into which the bumps 19.1 are buckled, achieving a position-limiting fit of the clamping structures and the grooves 20.
