Description

Technical Field

[0001] The invention relates to the technical field of furniture spring pads, and in particular to a spring module with a grid spring sleeve and a spring pad. Background Art

[0002] Furniture such as beds and sofa beds are essential components of people's lives. Most of the existing beds and sofa beds are provided with elastic pads. The elastic pads have a certain elasticity. When people lie on the beds and sofa beds, the elastic pads can provide a certain elastic support, which has a certain degree of comfort compared to hard pads.

[0003] Existing pocket spring mattresses are designed to prevent two or more people lying on the bed at the same time from affecting each other (for example, if the weight difference between the individuals is relatively large, one of them will inevitably affect the others when turning over or moving the body). In this type of mattress, each spring is individually packaged in a bag or sleeve made of non-woven fabric or other materials. The spring pockets are arranged in a diagram, and then the outer side of the arranged spring pocket group is covered by a whole piece of foam rubber by adhesion, bonding, etc. to form the required spring pad in the form of a furniture pad or furniture pad. However, the bag or sleeve will limit the elasticity of the spring to a certain extent, so that the elastic characteristics provided by this cloth bag spring bag are still limited, thereby reducing comfort. In addition, in the pocket spring mattress, the non-woven fabrics used to cover the pocket springs are adhered and entangled with each other. When the mattress is squeezed, the multiple pocket springs cannot move up and down completely independently, thereby affecting the comfort of the mattress.

[0004] In addition, the existing mattress has the disadvantage that it is very difficult to disassemble and assemble the bed. The existing elastic pad is usually an integrated, non-detachable and closed whole pad formed by a whole bottom layer, a spring layer, a sponge superimposed layer and a closed side surround. It cannot be disassembled and is not suitable for transportation and occupies a large space when stored. Summary of the invention

[0005] The main technical problem to be solved by the present invention is to provide a spring module and a spring pad with a grid spring sleeve, which can increase the overall elasticity of the spring bag while ensuring the elastic stability of the spring, and at the same time make the elastic pad more comfortable and easy to assemble and disassemble.

[0006] In order to solve the above technical problems, the present invention provides a spring module and a spring pad with a grid spring sleeve, which are as follows:

[0007] A spring module with a grid spring sleeve, the spring module is used to assemble to form an elastic pad; the spring module includes a connecting base and a plurality of elastic modules detachably assembled on the connecting base; the elastic modules constitute the main elastic supporting components of the spring module and the spring pad;

[0008] The elastic module comprises a spring fixing seat and a spring sleeve which are engaged with each other, and the spring sleeve is configured to accommodate the conical spring therein;

[0009] The spring sleeve has a grid-like structure.

[0010] In a preferred embodiment, the mesh density of the spring sleeve increases in a conical gradient.

[0011] In a preferred embodiment, the spring sleeve includes a ring opening, a top cover and a plurality of elastic support strips, wherein the plurality of elastic support strips are arranged at intervals in the circumferential direction around the ring opening, and the plurality of elastic support strips are staggered to form a grid-type elastic support frame.

[0012] In a preferred embodiment, the top cover is provided with a plurality of connecting plates at equal intervals along its edge along the circumferential direction; the elastic support strip fixedly connected to the connecting plate forms two fulcrums in a V shape, and the two fulcrums are fixedly connected to two positions of the ring mouth at a certain interval.

[0013] In a preferred embodiment, the two supporting points are arranged at a distance of 1 / 3-1 / 4 of the circumference of the ring opening.

[0014] In a preferred embodiment, 4 to 8 spring modules are assembled on one connecting base.

[0015] In a preferred embodiment, the connecting base includes a first base and a second base, and the first base and the second base are rotatably hinged at one side of their ends;

[0016] The first base and the second base are rotated at the hinge end to have an end splicing structure or a side splicing structure.

[0017] In a preferred embodiment, the first base and the second base are arranged opposite to each other at the hinged end relative to one side of the hinge to form a first clamping member for clamping;

[0018] The first base and the second base are provided with second clamping parts which are arranged opposite to each other and are engaged with each other on the sides thereof which are connected by rotation and on the sides thereof which are separated from each other by rotation;

[0019] The connecting base is constructed with the rotating hinge so that the first base and the second base can be releasably engaged with each other by a second clip on the splicing side; or the connecting base is constructed with the rotating hinge so that the first base and the second base can be releasably engaged with each other by a first clip on the rotating end, and at this time, the connecting base is constructed to be releasably engaged with an adjacent connecting base by a second clip.

[0020] In a preferred embodiment, a rotating clamp and a joint member capable of forming a mutual engagement are provided at the ends of the first base and the second base away from the hinge end;

[0021] When the connecting base is rotated to splice the first base and the second base side, a releasable engagement is formed between the rotating clamp on one of the first base and the second base and the engaging piece on the other one.

[0022] In a preferred embodiment, when the connecting base is rotated to splice the first base and the second base ends, a rotating clamp on one connecting base and a coupling member on another connecting base form a releasable connection, thereby assembling to form the elastic pad.

[0023] In a preferred embodiment, the spring module is symmetrically assembled on the first base and the second base.

[0024] A spring pad is formed by assembling a plurality of spring modules with a grid spring sleeve.

[0025] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0026] 1. The present invention provides a grid-type spring module, which wraps the spring with a grid sleeve. The grid-type structure is set to provide a certain deformation space when the spring undergoes elastic deformation, and the grid structure itself also has a certain deformation amount, which can be deformed synchronously with the spring, thereby releasing the elastic deformation amount of the spring to the maximum extent, and at the same time, it can increase the overall elasticity of the spring bag while ensuring the elastic stability of the spring.

[0027] 2. The present invention provides a grid-type spring module. The grid structure adopts a V-shaped elastic support bar with two fulcrums as downward support. When the spring is deformed, the downward pressure can be decomposed to ensure that the spring moves up and down in the vertical direction, avoiding one-side deviation movement, which causes local collapse of the spring module bias, and ensures the elastic stability of the spring.

[0028] 3. The present invention provides a grid-type spring module, which is configured with a detachable and assembled connecting base with a grid-type spring module. The spring modules between the formed spring modules are completely independent structures. When squeezed, the spring modules will not stick to each other and can move up and down independently, so that the elastic pad has a better comfort.

[0029] 4. The present invention provides a symmetrically foldable spring module, which forms a folding storage structure or an unfolding splicing structure by rotating the connecting base. The connecting base is deformable, which is convenient for disassembly for storage, thereby effectively reducing the space occupied by the spring module during storage and transportation. At the same time, the spring module can be freely assembled and combined to form spring pads of different specifications and sizes when unfolded, which can significantly improve the convenience of assembling the elastic pad.

[0046] refer to Figure 1-Figure 10 The present embodiment provides a spring module 3 having a grid spring sleeve 12, wherein a plurality of the spring modules 3 are sequentially assembled to form an elastic pad. The spring module 3 comprises a connecting base 2 and a plurality of elastic modules 1 detachably assembled on the connecting base 2; the elastic modules 1 constitute the main elastic supporting components of the spring module 3 and the spring pad.

[0047] like Figure 1-Figure 2In this embodiment, the elastic module 1 includes a spring fixing seat 11 and a spring sleeve 12 that are engaged with each other, and the spring sleeve 12 is configured to accommodate the conical spring therein. In this embodiment, the spring sleeve 12 is integrally formed by injection molding and has a grid-like structure, and its shape, size, and density can all be varied.

[0048] Specifically, the present embodiment provides a spring sleeve 12, the spring sleeve 12 includes a ring opening 121, a top cover 122 and a plurality of elastic support strips 123, the plurality of elastic support strips 123 are arranged at intervals in the circumferential direction around the ring opening 121, and the plurality of elastic support strips 123 are staggered to form a grid-type elastic support frame. The grid-type elastic support portion has tension in the grid structure, and when the spring is deformed by force, the tension of the grid cooperates with the elastic force of the spring, so that the spring will not be significantly hindered when deformed, the elasticity of the spring is stabilized, and the spring can be ensured to maintain a normal elastic use state, and the tension of the grid cooperates with the elastic force of the spring to further improve the overall elasticity of the elastic module and increase the comfort of the elastic pad.

[0049] Specifically, the top cover 122 is provided with a number of connecting pieces 124 at equal intervals along the edge thereof in the circumferential direction; the elastic support strip 123 fixedly connected to the connecting piece 124 forms two fulcrums in a V shape, and the two fulcrums are respectively fixedly connected to two positions of the ring opening 121 at a certain interval, and at the same time, the two fulcrums are arranged at a distance of 1 / 3-1 / 4 of the circumference of the ring opening 121. Under the condition of ensuring the grid tension, the elastic support strip 123 is connected with a fulcrum at the force-bearing end of the top cover 122 that plays a supporting role, and at the same time, the support of the elastic support strip 123 is formed at the bottom ring opening 121 with two fulcrums. In the process of the grid tension moving up and down, the deflection of the elastic support strip 123 to both sides is reduced, which is conducive to exerting the efficiency of the spring. At the same time, the constant tension of the elastic support strip 123 in the same direction is ensured to make the grid tension run more smoothly.

[0050] The first embodiment, as Figure 3-Figure 7 , providing a connection base 2 with a foldable and unfoldable function, and assembling a plurality of spring modules 3 with grid spring sleeves 12 on the connection base 2 , and 4-8 spring modules 3 can be assembled on one connection base 2 .

[0051] The connecting base 2 includes a first base 21 and a second base 22, and the spring module 3 is symmetrically assembled on the first base 21 and the second base 22. The first base 21 and the second base 22 have a rotating hinge 23 on one side of their ends, and the first base 21 and the second base 22 rotate with the hinge end to have an end splicing structure or a side splicing structure to form a relative expansion or relative folding movement. When folding, the long side of the connecting base 2 is folded in half to reduce the space occupied by the long side. When storing, on the one hand, the foldable storage space is small and convenient for storage, and on the other hand, the length of the connecting base 2 is reduced to avoid the phenomenon of partial breakage during transportation due to excessive length.

[0052] In order to better maintain the relative folding and relative unfolding state of the connecting base 2, the first base 21 and the second base 22 are arranged relative to each other at the hinged end relative to one side of the hinge to form a first clamping piece 24 for engagement, and the first base 21 and the second base 22 are arranged relative to each other on the sides where they are spliced ​​by rotation and on the sides where they are rotated away from each other to form a second clamping piece 25 for engagement.

[0053] The specific operation is that the connecting base 2 is constructed with the rotating hinge 23 so that the first base 21 and the second base 22 can be releasably engaged with the second clamping piece 25 on the splicing side; or the connecting base 2 is constructed with the rotating hinge 23 so that the first base 21 and the second base 22 can be releasably engaged with the first clamping piece 24 on the rotating end, at this time, the connecting base 2 is constructed to be releasably engaged with the adjacent connecting base 2 with the second clamping piece 25.

[0054] like Figure 3-Figure 5 As shown, Figure 4 The unfolding process of the spring module 3 shown is mainly, when the connection base 2 assembled with the elastic module 1 rotates around the rotating hinge 23 with the first base 21 and the second base 22, the side of one of the bases is rotated to abut against the side of the other base, based on the side of the first base 21 or the second base 22, at this time, the second clamping piece 25 on the abutting splicing side is engaged, and the connection base 2 is folded and stored; when the connection base 2 assembled with the elastic module 1 rotates around the rotating hinge 23 with the first base 21 and the second base 22 , taking the short side of the first base 21 or the second base 22 (i.e. the short side where the rotating end is located) as the standard, the short side of one of the bases is rotated until it is against the short side of the other base, and the first clamping piece 24 on the abutting short side is engaged, and the connecting base 2 is unfolded; when the connecting base 2 is unfolded, the role of the second clamping piece 25 is transformed into a splicing and snapping action of the elastic pad, and the second clamping piece 25 on one connecting base 2 is engaged with the corresponding second clamping piece 25 on the other connecting base 2 to realize splicing to form a soft pad structure.

[0055] In this embodiment, the folding and unfolding structure of the spring module 3 is also equipped with a locking structure, such as Figure 6-Figure 7 The locking structure includes a rotating clamp 26 and a joint 27 which are arranged on both sides of the end of the spring module 3 and can be engaged with each other. The rotating clamp 26 is arranged to be able to swing back and forth around the pivot axis to releasably engage with the joint 27 opposite to it, and the joint 27 is arranged to be able to releasably engage with the rotating clamp 26 opposite to it. Specifically, it is arranged on one end of the first base 21 and the second base 22 relative to its rotation hinge 23. The first base 21 and the second base 22 are both provided with a rotating clamp 26 on one side of their respective ends, and a joint 27 is provided on the other side. The position relationship is that when the first base 21 and the second base 22 are relatively folded, the rotating clamp 26 of one of the first base 21 and the second base 22 can be relatively engaged with the joint 27 of the other base to form a lock.

[0056] The setting of the locking structure is used, on the one hand, to lock the first base 21 and the second base 22 after the first base 21 and the second base 22 are relatively folded when a connecting base 2 is folded and stored, and on the other hand, to lock the connecting bases 2 when multiple splicing is performed when the connecting bases 2 are unfolded. Under the setting of the locking structure, the first clamping member 24 and the second clamping member 25 are provided to serve as pre-positioning.

[0057] It should be noted that the first clamping member 24 and the second clamping member 25 can be of various types, and no matter what type of pre-positioning structure is adopted, as long as the adjacent bases can be pre-positioned. In this embodiment, the first clamping member 24 and the second clamping member 25 both include two pre-positioning structures with different structures. Specifically, in the first clamping member 24 and the second clamping member 25, one of them is set as a retractable elastic protrusion, and the other is set as a recess that can accommodate the elastic protrusion. After the elastic protrusion and the recess are aligned in the lateral direction, the balance of the pre-positioning of the adjacent bases can be further improved. Or the first clamping member 24 and the second clamping member 25 can adopt a hook and slot structure that can be engaged.

[0058] like Figure 7 In this embodiment, the rotating clamp 26 includes a hanging ear and a hook, and the engaging member 27 includes a receiving groove and a clamping column arranged in the receiving groove. In this way, when the rotating clamp 26 rotates, the hook is placed in the receiving groove and engages with the clamping column to achieve connection and locking. When the rotating clamp 26 rotates in the opposite direction, the hook and the clamping column are released to achieve unlocking. The hanging ear is used for hand-holding operation, and the rotating clamp 26 is rotated by the hanging ear to engage or disengage the hook and the clamping column, which is convenient for effective assembly and portable disassembly.

[0059] In this embodiment, when the spring module 3 is in the unfolded state, the second clamping member 25 on the single side of the connection base 2 is used as a pre-positioning for splicing, so that when the spring module 3 is assembled into a spring pad, multiple spring modules 3 are positioned and plugged with the second clamping members 25 corresponding to the connection base 2 in pairs, and the splicing sides of the connection base 2 are spliced ​​in sequence, and the two adjacent connection bases 2 are locked and connected together by the engagement of the rotating clamp 26 and the engaging member 27. When all the connection base plates complete the locking of the rotating clamp 26 and the engaging member 27 in pairs, multiple spring modules 3 are assembled into the elastic support layer of the elastic pad. The splicing method provided in this embodiment can significantly improve the convenience of assembling the elastic pad, and is easy to disassemble for storage, effectively reducing the space occupied by the elastic pad when it is stored.

[0060] The second embodiment, as Figure 8-Figure 12 , a spring module 3 with disassembly and assembly is provided, which includes a connecting base 2 and a plurality of elastic modules 1 that can be detachably assembled on the connecting base 2, and its assembly structure is:

[0061] The first base 21 and the second base 22 are provided with a slot that can be slidably connected with the elastic module 1, and the slot limits the elastic module 1 from being separated from the base in the vertical direction. The first base 21 and the second base 22 have one side as a sliding entrance for the elastic module 1, and a limiting structure is provided near the sliding entrance and corresponding to the location of the first elastic module 1, and the limiting structure is used to limit the elastic module 1 from sliding out of the sliding entrance.

[0062] The assembly sequence is that when the connecting base 2 is in a folded storage state, a single elastic module 1 is assembled. Assembling in the folded storage state can better operate the sliding connection of the elastic module 1 to the slot, and the long sides can interact with each other to avoid damage to the connecting base 2 caused by jamming and force during the assembly process.

[0063] like Figure 8 A sliding entrance is set at one end of the base 2 connected to set the rotating hinge 23, and is sealed with a card groove at the end away from the rotating hinge 23. In this embodiment, taking the four assemblies of the single-sided base as an example, they are assembled in sequence from the sliding entrance. When assembled to the fourth one, the fourth elastic module 1 is clamped near the sliding entrance and the elastic module 1 is limited by the limiting structure, so that it is fixed at the sliding entrance and completes the limitation of the remaining three elastic modules 1 by its own limitation.

[0064] In this embodiment, a sliding entrance is provided at one end of the connecting base 2 where the rotating hinge 23 is provided, so that when the connecting base 2 is unfolded, the two sliding entrances form a relative limit, thereby further completing the limit of the elastic module 1.

[0065] In this embodiment, the sliding connection structure connecting the base 2 and the elastic module 1 is that C-shaped slots with opposite notches are set on both side edges of the first base 21 and the second base 22; the spring fixing seat 11 of the elastic module 1 is clamped along its edge in the C-shaped slot to form a limit.

[0066] In this embodiment, the limiting structure is configured as a protrusion 28 formed by the base body being inclined and higher than the base sliding surface; the spring fixing seat 11 of the elastic module 1 is formed by its fixing seat body to form a recessed portion suitable for accommodating the protrusion 28.

[0067] Furthermore, the protrusion 28 is configured as an elastic sheet with an inclined surface, and the inclination angle of the inclined surface gradually tilts upward along the insertion direction of the elastic module 1, so as to form a releasable mutual engagement with the recessed portion to form a limit; when the elastic module 1 is inserted into the slot along the insertion direction, the elastic module 1 is moved inward along the length direction of the slot until it reaches a specified position, and when the elastic module 1 moves inward from the sliding entrance, the sliding surface of the spring fixing seat 11 of the elastic module 1 slides and squeezes the elastic sheet downward to make way, thereby ensuring the sliding of the elastic module 1 along the insertion direction, but when the elastic module 1 needs to slide against the insertion direction, it will be limited by the engagement between the elastic sheet and the recessed portion, and the setting position of the elastic sheet is just plugged into place when the last elastic module 1 is inserted into the sliding entrance, and the elastic sheet is just engaged with the recessed portion of the last elastic module 1.

[0068] The structure of the limit release structure is that a pressing portion is arranged on the side of the elastic sheet away from the sliding surface of the base, which is used to push the limit member out of the recessed portion to release the limit.

[0069] Similarly, the connection base 2 provided in the second embodiment has the same function of folding and unfolding as the connection base 2 in the first embodiment. Figure 10-12 shown.

[0070] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
