[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 December 5, 2023, with application number: 202311670174.4, and the name of the invention: "A spring module structure, spring pad and soft pad installed with a single spring". 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 structure for installing a single spring, a spring pad and an elastic pad. Background Art

[0004] Elastic mattresses, which form cushions and mattresses, are essential components of everyday life. Currently, most elastic mattresses are difficult to disassemble or difficult to restore after disassembly. However, with the advancement of modern life, large furniture, such as elastic mattresses, requires increasingly frequent disassembly and reassembly to accommodate population migration and outdoor leisure activities. During relocation, bed disassembly and reassembly is difficult, so sometimes still usable elastic mattresses are discarded to reduce the burden of relocation.

[0005] Existing elastic pads are usually one-piece, non-detachable and closed whole pads formed by a whole bottom layer, a spring layer, a sponge superimposed layer and a closed side panel. That is, the spring layer is arranged on the bottom layer, the sponge superimposed layer is arranged on the spring layer, and the closed side panel is connected between the sponge superimposed layer and the bottom layer to form a closed space.

[0006] In pursuit of detachable, movable and reconfigurable mattresses, it is common on the market to assemble modular spring pads into a compact space to form a large mattress. However, the spring pad is still an integral product, which cannot be disassembled and is not suitable for transportation and takes up a large space when stored. Moreover, this elastic pad is not only expensive, but also has poor stability in actual use, thereby reducing comfort. Summary of the Invention

[0058] 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.

[0059] 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. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] 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.

[0061] Referring to Figures 1 to 24, this embodiment provides a spring module 3 structure for single spring installation, wherein a plurality of spring modules 3 are sequentially assembled to form an elastic pad. The spring module 3 includes a connecting base 1 and a plurality of elastic modules 2 assembled on the connecting base 1.

[0062] The connecting base 1 includes a first base 12 and a second base 13. The first base 12 and the second base 13 are connected by a rotating hinge 14 on one side of their ends. The rotating hinge 14 allows the first base 12 and the second base 13 to form a relative folding or relative unfolding movement. When folding, the long side of the connecting base 1 is folded in half to reduce the space occupied by the long side. When stored, 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 1 is reduced to avoid local breakage during transportation due to excessive length. The connecting base 1 of the present invention can be used as the bottom of a spring pad, supported on a bed frame or other supporting surface, or as the top surface of a spring pad, with a flexible layer laid on it, or directly as a lying surface for human body contact. The connecting base 1 in the following embodiment is used as an example of a base. The connecting base structure as the top surface of the spring is the same as the bottom surface structure, except that it can be inverted when used as a spring pad.

[0063] In order to better maintain the relative folding and relative unfolding state of the connecting base 1, the first base 12 and the second base 13 are arranged relative to each other at the end of the hinge 14 on the side of the hinge 14 to form a first locking member 18; and at the same time, the first base 12 and the second base 13 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 first locking grooves 19.

[0064] The specific operation is that the connecting base 1 is constructed with the rotating hinge 14 so that the first base 12 and the second base 13 can be releasably engaged with each other through the first card slot 19 on the splicing side; or the connecting base 1 is constructed with the rotating hinge 14 so that the first base 12 and the second base 13 can be releasably engaged with each other through the first card slot 19 on the splicing side. At this time, the connecting base 1 is constructed to be releasably engaged with the adjacent connecting base 1 through the first card slot 19.

[0065] As shown in Figures 1-3, the unfolding process of the spring module 3 shown in Figure 2 is mainly used. When the connecting base 1 assembled with the elastic module 2 rotates around the rotating hinge 14 with the first base 12 and the second base 13, the long side of one of the bases is rotated to abut against the long side of the other base, and the first card groove 19 on the abutting splicing side is engaged. At this time, the connecting base 1 is folded and stored; when the connecting base 1 assembled with the elastic module 2 rotates around the first base 12 and the second base 13 When the hinge 14 rotates, the short side of the first base 12 or the second base 13 (that is, the short side where the rotating end is located) is used as the basis, and the short side of one of the bases is rotated until it is against the short side of the other base. At this time, the first fastener 18 on the abutting short side is engaged, and the connecting base 1 is now fully unfolded; when the connecting base 1 is unfolded, the function of the first slot 19 is transformed into realizing the splicing and snapping effect of the elastic pad, and the first slot 19 on one connecting base 1 is engaged with the corresponding first fastener 18 on the other connecting base 1 to realize splicing.

[0066] In this embodiment, the folding and unfolding structure of the spring module 3 is further configured with a locking structure, which includes a rotating clamp 31 and a coupling member 32 arranged on both sides of the end of the spring module 3 to form a mutually engaging engagement. The rotating clamp 31 is configured to be able to swing back and forth around the pivot axis to releasably engage with the coupling member 32 opposite thereto, and the coupling member 32 is configured to be able to releasably engage with the rotating clamp 31 opposite thereto. Specifically, the locking structure is arranged on one end of the first base 12 and the second base 13 relative to their rotation hinge 14. The first base 12 and the second base 13 are both provided with a rotating clamp 31 on one side of their respective ends, and a coupling member 32 on the other side. The positional relationship is such that when the first base 12 and the second base 13 are relatively folded, the rotating clamp 31 of one of the first base 12 and the second base 13 can engage with the coupling member 32 of the other base to form a locking engagement.

[0067] This locking structure is used, on the one hand, to lock the first base 12 and the second base 13 when the connecting base 1 is folded and stored, and on the other hand, to lock the connecting bases 1 when multiple connecting bases 1 are unfolded and connected. In this locking structure, the first clamping member 18 and the second clamping member 19 serve as pre-positioning.

[0068] It should be noted that the first latch 18 and the first slot 19 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 latch 18 and the first slot 19 each include two pre-positioning structures with different structures. Specifically, one of the first latch 18 and the first slot 19 is configured as a retractable elastic protrusion, and the other is configured as a recess that can accommodate the elastic protrusion. By aligning the elastic protrusion and the recess in the transverse direction, the balance of the pre-positioning of the adjacent bases can be further improved. Alternatively, the first latch 18 and the first slot 19 can adopt a hook-and-slot 15 structure that can engage.

[0069] The connection base 1 assembled with the elastic module 2 in this embodiment, with reference to Figures 4-12, has the following assembly structure:

[0070] The first base 12 and the second base 13 are provided with a card slot 15 that can be slidably connected with the elastic module 2. The card slot 15 limits the elastic module 2 from separating from the base in the vertical direction. The first base 12 and the second base 13 have one end as a sliding entrance 16 for the elastic module 2, and a limiting structure is provided near the sliding entrance 16 and corresponding to the location of the first elastic module 2. The limiting structure is used to limit the elastic module 2 from sliding out of the sliding entrance 16.

[0071] The assembly sequence is that when the connecting base 1 is in a folded storage state, a single elastic module 2 is assembled. Assembling in the folded storage state can better operate the sliding connection of the elastic module 2 to the slot 15, and the long sides can interact with each other to avoid damage to the connecting base 1 caused by jamming and force during the assembly process.

[0072] As shown in Figure 6, a sliding entrance 16 is provided at one end of the base 1 connected to set the rotating hinge 14, and is sealed with a card slot 15 at the end away from the rotating hinge 14. In this embodiment, taking the four assemblies of the single-sided base as an example, they are assembled in sequence from the sliding entrance 16. When the fourth one is assembled, the fourth elastic module 2 is clamped near the sliding entrance 16 and the elastic module 2 is limited by the limiting structure, so that it is fixed at the sliding entrance 16 and completes the limitation of the remaining three elastic modules 2 by its own limitation.

[0073] In this embodiment, a sliding entrance 16 is provided at one end of the connecting base 1 to set the rotating hinge 14, so that when the connecting base 1 is unfolded, the two sliding entrances 16 form a relative abutment limit, further completing the limit of the elastic module 2.

[0074] As shown in Figures 11-12, the sliding structure connecting the base 1 and the elastic module 2 is that C-shaped slots 15 with opposite notches are set on both side edges of the first base 12 and the second base 13; the spring fixing seat 21 of the elastic module 2 is clamped along its edge in the C-shaped slot 15 to form a limit.

[0075] As shown in Figures 7-10, the limiting structure is set as a raised portion 17 formed by the base body being inclined and higher than the base sliding surface as the limiting structure; the spring fixing seat 21 of the elastic module 2 is formed by its fixing seat body to form a recessed portion 221 suitable for receiving the raised portion 17.

[0076] Furthermore, the protrusion 17 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 2, which is used to form a releasable mutual engagement with the recessed portion 221 to form a limit; when the elastic module 2 is inserted into the card slot 15 along the insertion direction, the elastic module 2 is moved inward along the length direction of the card slot 15 until it reaches the specified position. When the elastic module 2 moves inward from the sliding entrance 16, the sliding surface of the spring fixing seat 21 of the elastic module 2 slides and squeezes the elastic piece downward to make way, ensuring the sliding of the elastic module 2 along the insertion direction. However, when the elastic module 2 needs to slide against the insertion direction, it will be limited by the engagement between the elastic piece and the recessed portion 221. The setting position of the elastic piece is just plugged into place when the sliding entrance 16 realizes the insertion of the last elastic module 2, and the elastic piece is just engaged with the recessed portion 221 of the last elastic module 2.

[0077] The structure of the limit release structure is as shown in FIG10 , in which a pressing portion 171 is provided on the side of the elastic piece away from the sliding surface of the base, for pushing the limit member out of the recessed portion 221 to release the limit.

[0078] In this embodiment, the provided connecting base 1 and elastic module 2 and the spring module 3 after the connecting base 1 and the elastic module 2 are spliced ​​together can be stacked in multiple pieces, as shown in Figures 14-17.

[0079] As shown in Figure 5 , the elastic module 2 includes a spring retainer 21 and a spring cover 22. The open end of the spring cover is fixed to the spring retainer. The spring cover 22 is configured to accommodate a spring 23 therein. The spring cover 22 maintains a cavity for the spring, and the spring retainer 21 corresponds to the cavity opening, allowing for the nesting of another spring cover 22. The spring cover can be provided with multiple straps between the spring retainer 21 and the spring cover 22, as shown in Figures 1-17 , or a flexible cloth cover, as shown in Figures 18-22 .

[0080] Due to the conical structure of the conical spring 23, conical nesting can be achieved. In this embodiment, the spring fixing seat 21 is opened with a maximum diameter corresponding to the conical spring 23, and a conical cavity is set in the spring sleeve 22 corresponding to the middle cavity structure of the conical spring 23. The spring sleeves 22 are plugged in and stacked through the provided opening.

[0081] The connecting base 1 is provided with a plurality of through holes 11 corresponding to the elastic modules 2. The through holes 11 provided on the connecting base 1 are adapted to the openings of the spring fixing seat 21, so that two or more spring modules 3 can be stacked. The through holes 11 provided on the connecting base 1 ensure that multiple stacking and nesting can be achieved after the connecting base 1 and the elastic modules 2 are spliced.

[0082] With this stackable structure, when disassembling and transporting, the whole can be broken down into parts to reduce the space occupied. In the initial installation state, the base 1 and the elastic module 2 can be independently stacked and transported, which is convenient for transportation and sale. The independent connection of the base 1 and the elastic module 2 can realize the replacement of damaged individual parts. When it is necessary to disassemble and transport again, the spring module 3 after splicing can be connected to the base 1 and the elastic module 2 for stacking and transportation, which can realize rapid disassembly and transportation and rapid assembly and use, saving time and effort.

[0083] The first embodiment, referring to Figures 18-22, is a bag spring housing 22, which provides an elastic pad formed by splicing and assembling a plurality of spring modules 3 described in the above embodiments.

[0084] In this embodiment, a spring module 3 assembled with a bag spring sleeve 22 is provided. When the spring module 3 is unfolded, as shown in Figure 19, the first card slot 19 on the single side of the connecting base 1 is used as a pre-positioning for splicing. In this way, when the spring module 3 is assembled into a spring pad 4, multiple spring modules 3 are positioned and plugged in with the first card slots 19 corresponding to the connecting bases 1 in pairs. The splicing sides of the connecting bases 1 are spliced ​​in sequence, and the two adjacent connecting bases 1 are locked together by the engagement of the rotating clamps 31 and the coupling members 32. When all the connecting base plates complete the locking of the rotating clamps 31 and the coupling members 32 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 stored.

[0085] As shown in Figure 20, in this embodiment, the rotating clamp 31 includes a hanging ear 311 and a hook, and the coupling member 32 includes a receiving groove and a clamping column arranged in the receiving groove. In this way, when the rotating clamp 31 rotates, the hook is placed in the receiving groove and engages with the clamping column to achieve connection locking. When the rotating clamp 31 rotates in the opposite direction, the hook and the clamping column are released to achieve unlocking.

[0086] The second embodiment, referring to Figures 23-24, is based on the elastic pad of the first embodiment to provide a soft pad 7 that can be used for furniture.

[0087] The soft cushion 7 comprises an elastic pad, a flexible cushioning layer 5, and a cloth cover 6, arranged sequentially on top of the elastic pad. The flexible cushioning layer 5 has a skirt with a hanging strap 51. The rotating clamp 31 includes a hook 311 for engaging with the hanging strap 51 to secure the flexible cushioning layer 5. In this embodiment, the hook 311 can be used to attach the hanging strap 51 to complete assembly of the soft cushion 7, or it can be used for manual operation. The hook 311 is used to rotate the rotating clamp 31 to engage or disengage the hook with the connecting post, facilitating efficient assembly and portable disassembly.

[0088] 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.
