Spring module with grid spring sleeve, spring module assembly and elastic pad

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority based on the Chinese patent application filed with the State Intellectual Property Office of China on November 16, 2023, with application number: 202311532903X, and the name of the invention: "A grid spring sleeve, spring module and spring pad". The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The invention relates to the technical field of furniture spring pads, and in particular to a spring module with a grid spring cover and a spring pad. Background Art

[0004] Furniture such as beds and sofa beds are essential components of people's lives. Most existing beds and sofa beds are equipped with elastic cushions. These cushions have a certain degree of elasticity, providing a certain degree of elastic support when people lie down on them, making them more comfortable than hard cushions.

[0005] Existing pocket spring mattresses are designed to prevent two or more people lying on the bed from interfering with each other (for example, if there is a relatively large weight difference between the individuals, one person will inevitably affect the others when turning over or moving their body). In this type of mattress, each spring is individually packaged in a bag or sleeve made of non-woven fabric or other material. The spring pockets are arranged in a diagram, and then the outer side of the arranged spring pocket group is covered with a whole piece of foam rubber through 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-shaped spring pocket are still limited, thereby reducing comfort. In addition, in the pocket spring mattress, the non-woven fabric used to cover the pocket springs adheres to each other and is entangled. When the mattress is compressed, the multiple pocket springs cannot move up and down completely independently, which affects the comfort of the mattress.

[0006] In addition, existing mattresses have the disadvantage of being very difficult to disassemble and assemble. Existing resilient mattresses are typically an integral, non-detachable, and closed mattress consisting of a solid bottom layer, spring layer, sponge layer, and closed side panels. This makes them difficult to transport and takes up a lot of space when stored.

[0007] Summary of the Invention

[0016] In a preferred embodiment, the V-shaped support bars are connected to two supporting points of the fixing base and are arranged at intervals of 1 / 3-1 / 4 of the circumference of the opening.

[0017] In a preferred embodiment, 4-8 spring modules are assembled on one connecting base.

[0018] In a preferred embodiment, the connecting base includes a first base and a second base, wherein the first base and the second base are hinged at one side of their ends;

[0019] The first base and the second base are rotated at the hinge end to have an end splicing structure or a side splicing structure.

[0020] In a preferred embodiment, the first base and the second base are provided with a first clamping member at the end portion where the hinge is provided and opposite to the side of the hinge to form a clamping member;

[0021] The first base and the second base are provided with second clamping members arranged opposite to each other on their sides for forming a joint by rotation and on their sides for forming a joint by rotation;

[0022] 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, at this time, the connecting base is constructed to be releasably engaged with an adjacent connecting base by a second clip.

[0028] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0029] 1. The present invention provides a grid-type spring module that houses a spring in a spring housing. The grid-like structure provides a certain amount of deformation space when the spring undergoes elastic deformation. The grid structure itself also has a certain amount of deformation and can deform synchronously with the spring, maximizing the elastic deformation of the spring. At the same time, it can increase the overall elasticity of the spring bag while ensuring the elastic stability of the spring.

[0030] 2. The present invention provides a grid-type spring module. The grid structure adopts V-shaped elastic support bars 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 unilateral movement that causes local collapse of the spring module bias, thereby ensuring the elastic stability of the spring.

[0031] 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 spring modules are completely independent structures. When squeezed, the spring modules will not adhere to each other and can move up and down independently, making the elastic pad more comfortable.

[0032] 4. The present invention provides a symmetrically foldable spring module that can be folded and stored or unfolded and spliced ​​by rotating the connecting base. The connecting base is deformable, facilitating disassembly for storage, effectively reducing the space occupied by the spring module during storage and transportation. Furthermore, when unfolded, the spring module can be freely assembled to form spring pads of varying sizes, significantly improving the ease of assembly of the elastic pad.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Referring to Figures 1-3, this embodiment provides a spring module 1 having a grid spring housing 12. Multiple spring modules 1 are sequentially assembled to form a spring module and an elastic pad. The spring module 3 includes a connecting base 2 and multiple elastic modules 1 detachably assembled to the connecting base 2. The elastic modules 1 constitute the primary elastic support components of the spring module 3 and the spring pad.

[0051] As shown in Figures 1-3, in this embodiment, the elastic module 1 includes a spring and a spring sleeve 12. The spring sleeve 12 is configured to accommodate a conical spring therein. The spring sleeve includes a fixing seat, a top cover, and a grid connected between the fixing seat and the top cover. The fixing seats can be engaged with each other to form an elastic module, or can be connected to a base plate to form an elastic module. In this embodiment, the top cover 122, the fixing seat 11, and the grid of the spring sleeve 12 can be integrally molded by injection molding, more specifically, they can be integrally molded by secondary injection molding. The top cover 122 and the fixing seat 11 are rigid, and the grid 12 is flexible or elastic. The shape, size, and density of the grid can vary.

[0052] Specifically, this embodiment provides a spring sleeve 12, wherein the spring sleeve 12 fixing seat is provided with an opening 121 and a plurality of support bars 123, which can be made of a flexible or elastic material. The plurality of support bars 123 are arranged at intervals around the circumference of the opening 121, and the plurality of support bars 123 are staggered to form a grid-like elastic support frame. An opening flange 124 is provided at the opening 121 of the spring sleeve 12. When the spring is inserted into the spring sleeve 12, one end of the conical spring abuts against the top end 122 of the spring sleeve 12, and the large end spring wire 121 of the conical spring abuts against the flange 124 at the open end of the spring sleeve 12.

[0053] The grid-like support frame has good tension due to its grid structure, which provides an initial preload force to the spring and stabilizes the shape of the spring. When the spring is deformed under pressure, the flexibility or elasticity of the grid cooperates with the elastic force of the spring, so that the spring will not be significantly hindered during deformation, thereby stabilizing the elasticity of the spring and ensuring that the spring can maintain a normal elastic usage state. In addition, 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.

[0054] Specifically, the top cover 122 is provided with a number of connecting parts 124 at equal intervals along its edges along the circumference; one of the connecting parts 124 extends two of the support bars 123 in a V-shape, and the V-shape forms two support bars 123, which are respectively connected to two positions of the opening 121 of the fixed seat at a certain interval. Preferably, the two fulcrums are provided at a distance of 1 / 3-1 / 4 of the circumference of the ring opening 121. When the spring is installed and pre-tightened, the support bar 123 is connected with a fulcrum at the force-bearing end of the top cover 122, which plays a supporting role, and at the same time, the support of the support bar 123 is formed at two fulcrums at intervals at the bottom ring opening 121. The flexible grid is tensioned, and the deflection of the support bar 123 to the sides is reduced during the up and down movement of the grid, which is beneficial to the efficiency of the spring. At the same time, it is ensured that the constant tension of the support bar 123 in the same direction makes the grid sleeve run more smoothly.

[0055] In the first embodiment, as shown in FIG. 4 to FIG. 8 , a connection base 2 that can be folded and unfolded is provided, and a plurality of spring modules 1 with grid spring sleeves 12 are assembled on the connection base 2 . Four to eight spring modules 1 can be assembled on one connection base 2 .

[0056] The connecting base 2 comprises a first base 21 and a second base 22, on which the spring module 1 is symmetrically assembled. The first and second bases 21, 22 are hinged at one end with a hinge 23. The first and second bases 21, 22 rotate around this hinge, forming an end-jointed structure or a side-jointed structure, allowing for relative expansion or folding. When folding, the long sides of the connecting base 2 are folded in half, reducing the space occupied by the long sides. This allows for convenient storage, while also reducing the length of the connecting base 2 to prevent it from being excessively long and potentially breaking during transport.

[0057] 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 the side of the hinge to form a first clamping member 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 member 25 for engagement.

[0058] 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 clip 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 clip 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 clip 25.

[0059] As shown in Figures 4 to 6, the unfolding process of the spring module 3 shown in Figure 5 is mainly used. When the connecting 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, and the second clamping member 25 on the abutting splicing side is engaged. At this time, the connecting base 2 is folded and stored; when the connecting 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 the first base 21 or the second base 22 is used as the reference. When rotating, with 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 reference, the short side of one of the bases is rotated until it abuts against the short side of the other base. At this time, the first clamping member 24 on the abutting short side is engaged, and the connecting base 2 is now fully unfolded. When the connecting base 2 is unfolded, the function of the second clamping member 25 is transformed into a splicing and snapping function of the elastic pad. The second clamping member 25 on one connecting base 2 is engaged with the corresponding second clamping member 25 on the other connecting base 2 to achieve splicing and forming a soft pad structure.

[0060] In this embodiment, the folding and unfolding structure of the spring module 3 is further configured with a locking structure. As shown in Figures 7 and 8, the locking structure includes a rotating clamp 26 and a coupling member 27 disposed on opposite sides of the end of the spring module 3, which are mutually engaged. The rotating clamp 26 is configured to swing back and forth about a pivot axis to releasably engage with the coupling member 27, and the coupling member 27 is configured to releasably engage with the rotating clamp 26. Specifically, the locking structure is disposed on one end of the first base 21 and the second base 22 relative to their respective rotation hinges 23. The first base 21 and the second base 22 are each provided with a rotating clamp 26 on one side and a coupling member 27 on the other side on both sides of their respective ends. The positional relationship is such that when the first base 21 and the second base 22 are folded relative to each other, the rotating clamp 26 of one of the first base 21 and the second base 22 can engage with the coupling member 27 of the other base to form a locking relationship.

[0061] The locking structure is provided for, on the one hand, locking the first base 21 and the second base 22 when the connecting base 2 is folded and stored, and, on the other hand, for locking the connecting bases 2 when multiple connecting bases 2 are unfolded. In addition to the aforementioned locking structure provided on both sides of the end, a clamping member is provided at the end, not on the side. The first clamping member 24 and the second clamping member 25 are provided to serve as positioning and connection.

[0062] It should be noted that the first and second clips 24, 25 can be of various types. Regardless of the type of pre-positioning structure, as long as the adjacent bases can be pre-positioned, it is sufficient. In this embodiment, the first and second clips 24, 25 each include two pre-positioning structures with different structures. Specifically, one of the first and second clips 24, 25 is configured as a retractable elastic protrusion, and the other is configured as a recessed portion that can accommodate the elastic protrusion. By aligning the elastic protrusion and recess in the transverse direction, the balance of the pre-positioning of adjacent bases can be further improved. Alternatively, the first and second clips 24, 25 can employ an engageable hook-and-slot structure.

[0063] As shown in Figure 8, in this embodiment, the rotating clamp 26 includes a hook and a lug, and the engaging member 27 includes a receiving groove and a clamping post disposed within the receiving groove. Thus, when the rotating clamp 26 rotates, the hook is placed in the receiving groove and engages with the clamping post to achieve connection and locking. When the rotating clamp 26 rotates in the opposite direction, the hook and the clamping post are released to achieve unlocking. The hook is used for manual operation, and the rotating clamp 26 is rotated by the hook to engage or disengage the hook and the clamping post, facilitating efficient assembly and portable disassembly.

[0064] In this embodiment, when the spring module 3 is in the unfolded state, the second clamping member 25 on the single side of the connecting base 2 is used as a pre-positioning for splicing. In this way, when the spring module 3 is assembled into a spring pad, multiple spring modules 3 are positioned and plugged in by the second clamping members 25 corresponding to the connecting bases 2 in pairs. The splicing sides of the connecting bases 2 are spliced ​​in sequence, and the two adjacent connecting bases 2 are locked together by the engagement of the rotating clamps 26 and the engaging members 27. When all the connecting bases are locked in pairs by the rotating clamps 26 and the engaging members 27, the 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 stored.

[0065] The second embodiment, as shown in FIG9 to FIG13, provides a spring module 3 with disassembly and assembly, which includes a connecting base 2 and a plurality of elastic modules 1 that can be detachably assembled on the connecting base 2. The assembly structure is as follows:

[0066] The first base 21 and the second base 22 are provided with a card slot that can be slidably connected with the elastic module 1. The card slot limits the elastic module 1 from separating from the base in the vertical direction. The first base 21 and the second base 22 use one side as the sliding entrance of 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. The limiting structure is used to limit the elastic module 1 from sliding out of the sliding entrance.

[0067] The assembly sequence is that when the connecting base 2 is in the 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.

[0068] As shown in Figure 7, a sliding entrance is provided at one end of the base 2 for setting a rotating hinge 23, and is sealed with a card slot 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.

[0069] 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.

[0070] 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 provided 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.

[0071] In this embodiment, the limiting structure is configured as a raised portion 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 into a recessed portion suitable for receiving the raised portion 28.

[0072] Furthermore, the protrusion 28 is configured as an elastic piece 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 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. 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 piece downward to make way, ensuring that the elastic module 1 slides along the insertion direction. However, when the elastic module 1 needs to slide against the insertion direction, it will be limited by the engagement between the elastic piece and the recessed portion. The setting position of the elastic piece is just inserted into the sliding entrance when the last elastic module 1 is inserted, and the elastic piece is just engaged with the recessed portion of the last elastic module 1. The structure of the release limit structure is that a pressing portion is provided on the side of the elastic piece away from the sliding surface of the base, which is used to pull the limit member out of the recessed portion to release the limit.

[0073] Similarly, the connection base 2 provided in the second embodiment has the same folding and unfolding functions as the connection base 2 in the first embodiment, as shown in FIG. 11 to FIG. 13 .

[0074] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this 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 scope of protection of the present invention.
