FIELD OF THE DISCLOSURE
The present disclosure relates to a connection structure for pre-compressed springs, and in particular relates to an elastic module connected by the connection structure.
BACKGROUND OF THE DISCLOSURE
An elastic cushion made of existing springs presents an elasticity as a whole, springs adjacent to a forced part are all subjected to force, so that the elastic cushion can withstand a greater force. However, a spring bed with the elastic cushion cannot change following a change in a posture of a human body due to a mounting structure of the springs in the elastic cushion. The springs independently provide elasticity. However, upper ends of the springs are usually connected in the elastic cushion, so that the springs are subjected to force as a whole. Therefore, it is important that the springs are respectively independently forced while not separating from each other, so that the elastic cushion is synchronically deformed following the posture of the human body.
BRIEF SUMMARY OF THE DISCLOSURE
The present disclosure provides an elastic module configured to be deformed following changes in pressure, and a boundary between forced springs and unforced springs in the elastic module will not be separated due to squeezing.
A first technical solution of the present disclosure is as follows.
An elastic module comprises multiple pre-compressed springs, the multiple pre-compressed springs contact or are adjacent to each other, upper ends of the multiple pre-compressed springs are separated, middle parts of the multiple pre-compressed springs comprise one or more connection members, and middle parts of side surfaces of a front row and a rear row of two adjacent rows of the multiple pre-compressed springs are connected together.
In a preferred embodiment, the one or more connection members drive the multiple pre-compressed springs to bend laterally.
In a preferred embodiment, heights of the one or more connection members are no less than 0.5 mm.
In a preferred embodiment, the multiple pre-compressed springs are multiple pre-compressed springs wrapped by flexible sleeves.
In a preferred embodiment, the flexible sleeves are cloth sleeves, mesh sleeves, or bands configured to tense two ends of the multiple pre-compressed springs.
In a preferred embodiment, the multiple pre-compressed springs are slim-waisted shapes. That is, upper and lower ends of the multiple pre-compressed springs are larger than middle parts of the multiple pre-compressed springs.
In a preferred embodiment, the multiple pre-compressed springs comprises first springs and second springs, diameters of the first springs are smaller than diameters of the second springs, the first springs and the second springs are staggered.
In a preferred embodiment, the second springs are slim-waisted shapes, and the first springs are shaped as waist drums.
In a preferred embodiment, connection seats of the one or more connection members are outer rings disposed on middle parts of the flexible sleeves, and the outer rings are loops of bands or the bands spaced apart. As an option, the connection seats are made of plastic or other materials.
In a preferred embodiment, the one or more connection members have quadrilateral shapes, and the one or more connection members are clamped to waists of the multiple pre-compressed springs.
In a preferred embodiment, the middle parts of the multiple pre-compressed springs are buckled to each other by the one or more connection members. As an option, two adjacent connection members of the one or more connection members are connected by a third member.
In a preferred embodiment, bottom parts of the multiple pre-compressed springs of the elastic module are disposed on a bottom plate or a flexible material.
A second technical solution of the present disclosure is as follows.
An elastic mattress comprises one or more the elastic modules, a plurality of the one or more the elastic modules are spliced together, or an outer periphery of the plurality of the elastic modules is encompassed by a band.
The middle parts of the one or more pre-compressed springs of the spring module of the present disclosure are connected together, and the upper ends of the one or more pre-compressed springs are free to move without interference. Therefore, the upper ends of the one or more pre-compressed springs are respectively independently forced. Unforced springs (i.e., springs to which force is not applied) of the one or more pre-compressed springs adjacent to the forced springs (i.e., springs to which force is applied) of the one or more pre-compressed springs will not be moved away from the forced springs to prevent generation of a boundary cavity due to pulling of the one or more connection members, and the spring module, as a whole, is compact. The one or more connection members of the present disclosure have suitable heights to drive the one or more pre-compressed springs to deform in a lateral direction and to extend following the application of the force. Structures of the one or more connection members are simple and easily connected.

Embodiment 1
As shown in FIGS. 1 and 2, one or more pre-compressed springs 1 comprise one or more springs 11 and one or more cloth sleeves 12. The one or more springs 11 are wrapped by the one or more cloth sleeves 12. After the one or more springs 11 are disposed in the one or more cloth sleeves 12, rear ends of the one or more cloth sleeves 12 are squeezed and tied to define knotted tops 13, and the knotted tops 13 are disposed in narrowed openings or top cover holes of the one or more pre-compressed springs 1. One or more connection members 20 are clamped to the waists of the one or more pre-compressed springs 1. The one or more connection members 20 comprise connection seats 2, front convex buckles 3, and rear concave buckles 4, and the connection seats 2 are disposed on waists of the one or more pre-compressed springs 1. Each of the connection seats 2 is an outer ring 22 disposed on a middle part of a corresponding one of the cloth sleeves 12, and the outer ring 22 is a loop of a band or bands spaced apart. At least two opposite sides of each of the connection seats 2 comprise slots 21. The front convex buckles 3 are fixed to front ends of the slots 21, and the rear concave buckles 4 are fixed to rear ends of the slots 21. Each of the front convex buckles 3 comprise two clamping tabs 31 spaced apart. At least one of the two clamping tabs 31 is hollow. At least one outside wall of the two clamping tabs 31 is a cantilevered arm 32. The two clamping tabs 31 comprise clamping structures 33, and a tail end of the cantilevered arm 32 is a platform 34. Each of the rear concave buckles 4 comprise two clamping holes 41 adapted to the two clamping tabs 31.
A connection between the one or more pre-compressed springs 1 is shown in FIGS. 3-5. A waist (i.e., a middle part) of each of the one or more pre-compressed springs 1 comprise a corresponding one of the one or more connection members 20. Two adjacent rows (i.e., a front row and a rear row) of the one or more pre-compressed springs 1 are staggered, and the front convex buckles 3 of the one or more connection members 20 in the rear row of the one or more pre-compressed springs 1 are inserted into the rear concave buckles 4 in the front row of the one or more pre-compressed springs 1 to achieve a connection of the front row and the rear row of the one or more pre-compressed springs 1. The front convex buckles 3 can be detached from the rear concave buckles 4 by pushing the platform 34 of the front convex buckles 3 to be separated from the connection between the one or more pre-compressed springs 1.
Each of the connection seats 2, a corresponding one of the front convex buckles 3, and a corresponding one of the rear concave buckles 4 can be an integral structure or be separate elements and then connected together. Advantages of separation of each of the connection seats 2, the corresponding one of the front convex buckles 3, and the corresponding one of the rear concave buckles 4 are that different materials and different strengths can be selected.
Upper ends of the one or more pre-compressed springs 1 are separated (i.e., are not connected together).
In this embodiment, multiple pre-compressed springs of the one or more pre-compressed springs 1 define an elastic module (i.e., a spring module) 100.
