Description

RELATED APPLICATIONS

This application claims priority to Chinese patent application number 202311532903.X, filed on Nov. 16, 2023. Chinese patent application number 202311532903.X is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to the field of elastic cushions for furniture, and in particular to a structure of a plurality of spring modules having mesh spring sleeves and an elastic cushion.

BACKGROUND OF THE DISCLOSURE

Beds, sofa beds, and other types of furniture are essential components of daily life. Most existing beds and sofa beds are equipped with elastic cushions. These elastic cushions provide a certain level of elasticity, offering some degree of comfort compared to rigid cushions when people lie down on them.

Current pocket spring mattresses are designed to prevent mutual disturbances between two or more people lying on the bed (for instance, when there is a significant weight difference between individuals, one person's turning or movement inevitably affects the others). In this type of mattress, each spring is individually encased in a bag or sleeve made of non-woven fabric or other materials. The spring bags are arranged in a specific pattern, and the outer sides of the assembled spring bags are covered with a piece of foam rubber through adhesion or bonding, forming the desired spring cushion. However, the bags or sleeves somewhat limit the spring's elasticity, and the bags or sleeves provide limited elasticity, thereby reducing comfort. Additionally, in pocket spring mattresses, the non-woven fabric covering the spring bags tends to stick and pull against each other. When the mattress is compressed, the pocket springs cannot move independently and vertically, which affects comfort of the mattress.

Moreover, existing mattresses also have the disadvantage of being very difficult to disassemble and assemble. Current elastic cushions are typically integrated, non-detachable, and enclosed units formed by a single base layer, a spring layer, a sponge overlay, and enclosed sidewalls. They cannot be disassembled, are difficult to transport, and take up a large amount of space when stored.

BRIEF SUMMARY OF THE DISCLOSURE

The technical problem to be solved by the present disclosure is to provide a structure of a plurality of spring modules having mesh spring sleeves and an elastic cushion, which can enhance an overall elasticity of a spring pocket while ensuring stability of an elasticity of a spring. At the same time, comfort of the elastic cushion is improved, and the elastic cushion is easier to assemble and disassemble.

In order to solve the above technical problems, the present disclosure provides a structure of a plurality of spring modules having mesh spring sleeves and an elastic cushion.

The structure of the plurality of spring modules having the mesh spring sleeves is provided, and the plurality of spring modules are configured to be sequentially assembled to form an elastic cushion. Each of the plurality of spring modules comprises a connecting base and a plurality of elastic modules assembled on the connecting base. The plurality of elastic modules are configured to supply an elastic supporting force to the plurality of spring modules and the elastic cushion.

Each of the plurality of elastic modules comprises a spring fixing seat and a spring sleeve engaged with each other, and the spring sleeve is configured to accommodate a conical spring in the spring sleeve.

The spring sleeve has a mesh-hole structure.

In a preferred embodiment, a mesh density of the mesh-hole structure of the spring sleeve increases in a direction from a large end of the conical spring to a small end of the conical spring.

In a preferred embodiment, the spring sleeve comprises an annular opening, a top cover, and a plurality of elastic support strips. The plurality of elastic support strips are spaced apart from one another along a circumferential direction of the annular opening, and the plurality of elastic support strips intersect to form the mesh-hole structure.

In a preferred embodiment, the top cover comprises a plurality of connecting pieces spaced evenly apart from one another along an edge of the top cover in a circumferential direction of the top cover, and each of the plurality of elastic support strips is inverted V-shaped and has two supporting points. Each of the plurality of connecting pieces is fixedly connected to a corresponding one of the plurality of elastic support strips, and the two supporting points of each of the plurality of elastic support strips are fixedly connected to two positions of the annular opening at a specific interval.

In a preferred embodiment, the specific interval between the two supporting points is ⅓ to ¼ of a circumference of the annular opening.

In a preferred embodiment, the connecting base of each of the plurality of spring modules is assembled with 4-8 spring modules of the plurality of spring modules.

In a preferred embodiment, the connecting base comprises a first base and a second base, and a first side of a rotating end of the first base and a first side of a rotating end of the second base are pivotally connected to each other through a rotating hinge.

The first base and the second base are pivotally connected to each other on the rotating end of the first base and the rotating end of the second base to form an end splicing structure or a side splicing structure.

A second side of the rotating end of the first base relative to the rotating hinge and a second side of the rotating end of the second base relative to the rotating hinge are respectively disposed with two first buckling members opposite to each other and configured to be buckled to each other.

A splicing side of the first base and a splicing side of the second base, which are configured to be spliced to or separated from each other during rotating movement of the connecting base, are respectively disposed with two second buckling members opposite to each other and configured to be buckled to each other.

The rotating hinge enables the connecting base to be rotated so that the connecting base is configured such that the first base and the second base are configured to be releasably engaged with each other through the two second buckling members on the splicing side of the first base and the splicing side of the second base. The rotating hinge enables the connecting base to be rotated so that the connecting base is configured such that the first base and the second base are configured to be releasably engaged with each other through the two first buckling members on the rotating end of the first base and the rotating end of the second base while the connecting base is configured to be releasably engaged with an adjacent connecting base through a corresponding one of the two second buckling members.

In a preferred embodiment, an end of the first base away from the rotating end of the first base and an end of the second base away from the rotating end of the second base each comprise a rotating buckling member and an engaging member configured to be buckled to each other.

When the connecting base is rotated to enable a splicing side of the first base and a splicing side of the second base to abut each other, the rotating buckling member of one of the first base or the second base is buckled to the engaging member of the other one of the first base or the second base.

When the connecting base is rotated to enable the rotating end of the first base and the rotating end of the second base to abut each other, the rotating buckling member of one of the connecting base or the adjacent connecting base is buckled to the engaging member of the other one of the connecting base or the adjacent connecting base to be assembled to form the elastic cushion.

In a preferred embodiment, the plurality of spring modules are symmetrically assembled on the first base and the second base.

An elastic cushion, comprising the structure of the plurality of spring modules having the mesh spring sleeves according to any one of claims.

Compared with the existing techniques, the technical solution has the following advantages.

• • 1. The present disclosure provides the plurality of spring modules having the mesh spring sleeves. The spring sleeve, which has the mesh-hole structure, wraps around the conical spring. The mesh-hole structure allows for a certain amount of deformation space when the conical spring undergoes elastic deformation. The mesh-hole structure itself also has a certain degree of deformability, enabling the mesh-hole structure to deform in sync with the conical spring. This maximizes release of elastic deformation of the spring, while simultaneously increasing overall elasticity of the spring sleeve, ensuring stability of elasticity of the conical spring.
  • 2. The present disclosure provides the plurality of spring modules having the mesh spring sleeves. The mesh-hole structure uses the plurality of elastic support strips, which is inverted V-shaped and has the two supporting points for downward pressure support. When the conical spring deforms, the downward pressure is distributed by the plurality of elastic support strips, ensuring that the conical spring moves vertically up and down. This prevents lateral movement that could cause the plurality of spring modules to tilt and collapse locally, thereby maintaining the stability of the elasticity of the conical spring.
  • 3. The present disclosure provides the plurality of spring modules having the mesh spring sleeves. Each of the plurality of spring modules comprises a detachable and assemblable connecting base. The plurality of spring modules are completely independent of each other, preventing any adhesion or pulling between the plurality of spring modules when compressed. This allows for independent vertical movement of the plurality of spring modules, resulting in the elastic cushion with better comfort.
  • 4. The present disclosure provides the plurality of spring modules having a symmetrical and foldable structure. The connecting base can be rotated to form a folding storage structure or an expanded splicing structure. The connecting base can deform, making it easy to disassemble for storage, which effectively reduces a space occupied by each of the plurality of spring modules during storage and transportation. At the same time, the plurality of spring modules can be freely assembled and combined to form the elastic cushion of different specifications and sizes. This can significantly enhance the convenience of assembling the elastic cushion and make it easy to disassemble for storage.

For example, “connected” can be a wall hanging connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be a connection in two members. For those of ordinary skill in the art, the specific meaning of the above terms in the present disclosure can be understood under specific conditions.

Referring to FIGS. 1 to 10, this embodiment provides a structure of a plurality of spring modules 3 having mesh spring sleeves, and the plurality of spring modules 3 are configured to be sequentially assembled to form an elastic cushion. Each of the plurality of spring modules 3 comprises a connecting base 2 and a plurality of elastic modules 1 assembled on the connecting base 2. The plurality of elastic modules 1 are configured to supply an elastic supporting force to the plurality of spring modules 3 and the elastic cushion.

Referring to FIGS. 1 to 2, in this embodiment, each of the plurality of elastic modules 1 comprises a spring fixing seat 11 and a spring sleeve 12 engaged with each other, and the spring sleeve 12 is configured to accommodate a conical spring 10 therein. In this embodiment, the spring sleeve 12 is integrally formed by injection molding and has a mesh-hole structure, whose shape, size, and density can vary.

Specifically, this embodiment provides the spring sleeve 12, and the spring sleeve 12 comprises an annular opening 121, a top cover 122, and a plurality of elastic support strips 123. The plurality of elastic support strips 123 are spaced apart from one another along a circumferential direction of the annular opening 121, and the plurality of elastic support strips 123 intersect to form a mesh-like elastic support frame (i.e., the mesh-hole structure). The mesh-like elastic support frame has tension. When the conical spring 10 deforms under force, the tension of the mesh-like elastic support frame cooperates with an elastic force of the conical spring 10, ensuring that the conical spring 10 is not significantly obstructed during deformation, thus stabilizing the elasticity of the conical spring 10 and ensuring the conical spring 10 is maintained in a normal elastic state. Moreover, combination of the tension of the mesh-like elastic support frame and the elastic force of the conical spring 10 further enhances overall elasticity of the plurality of spring modules 3, increasing comfort of the elastic cushion.

Specifically, the top cover 122 comprises a plurality of connecting pieces 124 spaced evenly apart from one another along an edge of the top cover 122 in a circumferential direction of the top cover 122. Each of the plurality of elastic support strips 123 is inverted V-shaped and has two supporting points. Each of the plurality of connecting pieces 124 is fixedly connected to a corresponding one of the plurality of elastic support strips 123, and the two supporting points of each of the plurality of elastic support strips 123 are fixedly connected to two positions of the annular opening 121 at a specific interval. The specific interval between the two supporting points can be ⅓ to ¼ of a circumference of the annular opening 121. Ensuring the tension of the mesh-like elastic support frame, each of the plurality of elastic support strips 123 comprises a top supporting point connected to a force-bearing end of the top cover 122 which has a supporting effect, while the two supporting points of each of the plurality of elastic support strips 123 is spaced apart on the annular opening 121, forming a supporting function of the plurality of elastic support strips 123. This reduces a lateral deflection of each of the plurality of elastic support strips 123 during vertical movement of the mesh-like elastic support frame, improving efficiency of the conical spring 10. Additionally, constant tension in the plurality of elastic support strips 123 in a same direction ensures that the tension in the mesh-hole structure operates more smoothly.

In a first embodiment, referring to FIG. 3 to FIG. 7, the connecting base 2 is configured to be folded and unfolded. The plurality of spring modules 3 having mesh spring sleeves are sequentially assembled on the connecting base 2. The connecting base 2 can be assembled with 4-8 spring modules 3 of the plurality of spring modules 3.

The connecting base 2 comprises a first base 21 and a second base 22, and the plurality of spring modules 3 are symmetrically assembled on the first base 21 and the second base 22. A first side of a rotating end of the first base 21 and a first side of a rotating end of the second base 22 are pivotally connected to each other through a rotating hinge 23. The first base 21 and the second base 22 are pivotally connected to each other on the rotating end to form an end splicing structure or a side splicing structure to have relative folding movement or relative unfolding movement. When folding, a long side of the connecting base 2 is folded in half to reduce an occupying space of the long side of the connecting base 2. When storing, a storage space of the connecting base 2 after the connecting base 2 is folded is small and the connecting base 2 is convenient for storage. Additionally, a length of the connecting base 2 is reduced to avoid partial breakage during transportation due to excessive length.

To better maintain a relative folded state and a relative unfolded state of the connecting base 2, a second side of the rotating end of the first base 21 relative to the rotating hinge 23 and a second side of the rotating end of the second base 22 relative to the rotating hinge 23 are respectively disposed with two first buckling members 24 opposite to each other and configured to be buckled to each other. A splicing side of the first base 21 and a splicing side of the second base 22, which are configured to be spliced to or separated from each other during rotating movement of the connecting base 2, are respectively disposed with two second buckling members 25 opposite to each other and configured to be buckled to each other.

A specific operation is that the rotating hinge 23 enables the connecting base 2 to be rotated, so that the connecting base 2 is configured such that the first base 21 and the second base 22 can be releasably engaged with each other through the two second buckling members 25 on the splicing side of the first base 21 and the splicing side of the second base 22. Additionally, the rotating hinge 23 enables the connecting base 2 to be rotated, so that the connecting base 2 is configured such that the first base 21 and the second base 22 can be releasably engaged with each other through the two first buckling members 24 on the rotating end of the first base 21 and the rotating end of the second base 22. At this time, the connecting base 2 is configured to be releasably engaged with an adjacent one of the connecting bases 2 through a corresponding one of the two second buckling members 25.

Referring to FIGS. 3-5, an unfolding process of each of the plurality of spring modules 3 is shown. When the first base 21 and the second base 22 of the connecting base 2 assembled with the plurality of elastic modules 1 is rotated around the rotating hinge 23, a long side of one of the first base 21 or the second base 22 is rotated to abut a long side of the other one of the first base 21 or the second base 22, where the long side of the other one of the first base 21 or the second base 22 is stationary. At this time, the two second buckling members 25 on the splicing side of the first base 21 and the splicing side of the second base 22 abutting each other are buckled to each other to enable the connecting base 2 to be folded for storage. When the first base 21 and the second base 22 of the connecting base 2 assembled with the plurality of elastic modules 1 is rotated around the rotating hinge 23, a short side (i.e., on which the rotating end is located) of one of the first base 21 or the second base 22 is rotated to abut a short side (i.e., on which the rotating end is located) of the other one of the first base 21 or the second base 22, where the short side of the other one of the first base 21 or the second base 22 is stationary. At this time, the two first buckling members 24 on the short side of the first base 21 and the short side of the second base 22 abutting each other are buckled to each other to enable the connecting base 2 to be unfolded. When the connecting base 2 is in an unfolded state, a function of the two second buckling members 25 is transformed into realizing a splicing and snapping action of the connecting base 2 to form the elastic cushion, and a corresponding one of the two second buckling members 25 on one of the connecting bases 2 is engaged with a corresponding one of the two second buckling members 25 on another one of the connecting bases 2 to realize splicing.

In this embodiment, a folding and unfolding structure of each of the plurality of spring modules 3 further comprises two locking structures, and each of the two locking structures comprises a rotating buckling member 26 and an engaging member 27 configured to be buckled to each other. Two end portions of each of the plurality of spring modules 3 are respectively disposed with the two locking structures, and two sides of each of the two end portions of each of the plurality of spring modules 3 are respectively disposed with the rotating buckling member 26 and the engaging member 27. The rotating buckling member 26 is configured to swing back and forth around a pivot axis to be releasably engaged with the engaging member 27 corresponding thereto. The engaging member 27 is configured to be releasably engaged with the rotating buckling member 26 corresponding thereto. Specifically, the two locking structures are respectively disposed on an end portion of the first base 21 opposite to the rotating hinge 23 and an end portion of the second base 22 opposite to the rotating hinge 23. Two sides of the end portion of the first base 21 are respectively disposed with the rotating buckling member 26 and the engaging member 27, and two sides of the end portion of the second base 22 are respectively disposed with the rotating buckling member 26 and the engaging member 27. A position relationship is that when the first base 21 and the second base 22 are relatively folded, the rotating buckling member 26 of one of the first base 21 or the second base 22 can be relatively engaged with the engaging member 27 of the other one of the first base 21 or the second base 22 to form a locking connection.

The two locking structures are configured to enable the first base 21 and the second base 22 to be locked after the first base 21 and the second base 22 are relatively folded when the connecting base 2 is folded for storage. Additionally, the two locking structure are configured to enable adjacent two of the connecting bases 2 to be locked when the connecting base 2 is unfolded for splicing. In an arrangement of the locking structure, the two first buckling members 24 and the two second buckling members 25 are provided to serve as pre-positioning.

It should be noted that the two first buckling members 24 and the two second buckling members 25 can be of various types, and the type of pre-positioning structure that is adopted does not matter, as long as the adjacent bases (i.e., the first base 21 and the second base 22, or the adjacent two of the connecting bases 2) can be pre-positioned. In this embodiment, the two first buckling members 24 can be divided into two pre-positioning structures with different structures, and the two second buckling members 25 can be divided into two pre-positioning structures with different structures. Specifically, one of the two first buckling members 24 or one of the two second buckling members 25 is an extendable elastic protrusion, and the other one of the two first buckling members 24 or the other one of the two second buckling members 25 is a recess that can accommodate the extendable elastic protrusion. After the extendable elastic protrusion and the recess are aligned in a lateral direction, a balance of pre-positioning of the adjacent bases can be further improved. Alternatively, the two first buckling members 24 and the two second buckling members 25 can adopt a hook and slot structure that can be engaged with each other.

As shown in FIG. 7, in this embodiment, the rotating buckling member 26 comprises a hanging lug 261 and a hanging hook 262, and the engaging member 27 comprises a receiving groove 271 and a buckling column 272 disposed in the receiving groove 271. In this way, when the rotating buckling member 26 is rotated, the hanging hook 262 is disposed in the receiving groove 271 and is buckled to the buckling column 272 to achieve a locking connection. When the rotating buckling member 26 is rotated in an opposite direction, the hanging hook 262 is released from the buckling column 272 to achieve unlocking. The hanging lug 261 can be operated by hand, and the rotating buckling member 26 is rotated by the hanging lug 261 to be buckled to or separated from the buckling column 272, which is convenient for effective assembly and portable disassembly.

In this embodiment, when each of the plurality of spring modules 3 is unfolded, the two second buckling members 25 of the connecting base 2 serve as pre-positioning, so that when the plurality of spring modules 3 are assembled to form the elastic cushion, the plurality of the spring modules 3 are pre-positioned through the adjacent two of the connecting bases 2 being connected to each other through the two second buckling members 25, and the spliced sides (i.e., of the first base 21 and the second base 22) of the connecting base 2 are sequentially spliced together. The adjacent two of the connecting bases 2 are locked and connected together through an engagement of the rotating buckling member 26 and the engaging member 27. When all of the connecting bases 2 complete locking between the rotating buckling member 26 and the engaging member 27, the plurality of spring modules 3 are assembled to form an elastic supporting layer of the elastic cushion. A splicing method provided by this embodiment can significantly improve convenience of assembling the elastic cushion and facilitate disassembly for storage, effectively reducing a space occupied by the elastic cushion when the elastic cushion is stored.

In a second embodiment, referring to FIG. 8 to FIG. 12, each of the plurality of spring modules 3 having a disassembly and splicing structure comprises a connecting base 2 and a plurality of elastic modules 1 assembled on the connecting base 2. An assembly structure is described as follow.

Each of the first base 21 and the second base 22 comprises a buckling groove 211 that can be slidably connected to the plurality of elastic modules 1. The buckling groove 211 is interlocked with the plurality of elastic modules 1 to inhibit the plurality of elastic modules 1 from being separated from the connecting base 2 in a vertical direction. One end of each of the first base 21 and the second base 22 comprises a sliding entrance 241 for the plurality of elastic modules 1, and a position-limiting structure (e.g., a protruding portion 28) is disposed adjacent to the sliding entrance 241 and corresponding to a location of a first elastic module 1 of the plurality of elastic modules 1. The position-limiting structure is used to inhibit the plurality of elastic modules 1 from sliding out of the sliding entrance 241.

An assembly sequence is that when the connecting base 2 is in a folded storage state (i.e., the relative folded state), each of the plurality of elastic modules 1 is independently assembled. Assembling in the folded storage state can enable better operation of a sliding connection of the plurality of elastic modules 1 to the buckling groove 211. The long sides of the first base 21 and the second base 22 abut each other to avoid damage to the connecting base 2 caused by jamming and force during an assembly process.

As shown in FIG. 8, the rotating end of each of the first base 21 and the second base 22 disposed with the rotating hinge 23 comprises the sliding entrance 241, and an end of each of the first base 21 and the second base 22 away from the rotating hinge 23 is closed for closing the buckling groove 211. In this embodiment, taking four elastic modules 1 of the plurality of elastic modules 1 being assembled to a single-sided base (i.e., the first base 21 or the second base 22) as an example, the four elastic modules 1 of the plurality of elastic modules 1 are assembled in sequence from the sliding entrance 241. When a fourth elastic module 1 of the four elastic modules 1 of the plurality of elastic modules 1 is assembled, the fourth elastic module 1 of the four elastic modules 1 of the plurality of elastic modules 1 is buckled adjacent to the sliding entrance 241 and the fourth elastic module 1 is interlocked with the position-limiting structure, so that the fourth elastic module 1 is fixed at the sliding entrance 241 and enables movement of the remaining three elastic modules 1 of the four elastic modules 1 of the plurality of elastic modules 1 to be inhibited by the fourth elastic module 1.

In this embodiment, the rotating end of each of the first base 21 and the second base 22 disposed with the rotating hinge 23 comprises the sliding entrance 241, so that when the connecting base 2 is unfolded, the sliding entrance 241 of the first base 21 and the sliding entrance 241 of the second base 22 abut each other to form a relative movement limitation, thereby further completing an interlocking connection of the plurality of elastic modules 1.

In this embodiment, a sliding structure between the connecting base 2 and the plurality of elastic modules 1 is that the buckling groove 211 comprises two C-shaped buckling grooves 15 defined on two side edges of the first base 21 or the second base 22, and groove openings of the two C-shaped buckling grooves 15 face each other. An edge of a spring fixing seat 11 of each of the plurality of elastic modules 1 is buckled to the two C-shaped buckling grooves 15 to form a position limitation.

In this embodiment, a base body 212 of the first base 21 or the second base 22 is inclined and higher than a base sliding surface 213 of the first base 21 or the second base 22 to form the protruding portion 28 as the position-limiting structure. A fixing seat body 111 of the spring fixing seat 11 of each of the plurality of elastic modules 1 is formed with a recessed portion configured for accommodating the protruding portion 28.

Furthermore, the protruding portion 28 is configured as an elastic sheet with an inclined surface, and an inclination angle of the inclined surface gradually tilts upward along an insertion direction of each of the plurality of elastic modules 1, so as to form a releasable buckling connection with the recessed portion. When each of the plurality of elastic modules 1 is inserted into the buckling groove 211 along the insertion direction, each of the plurality of elastic modules 1 is moved inward along a length direction of the buckling groove 211 until approaching a specified position. When each of the plurality of elastic modules 1 moves inward from the sliding entrance 241, a sliding surface of the spring fixing seat 11 of each of the plurality of elastic modules 1 slides to squeeze the elastic sheet downward, thereby ensuring sliding of each of the plurality of elastic modules 1 along the insertion direction. However, when the plurality of elastic modules 1 need to slide against the insertion direction, the recessed portion of a last elastic module 1 of the plurality of elastic modules 1 on the first base 21 or the second base 22 will be interlocked with the elastic sheet. The elastic sheet is just inserted into place when the last elastic module 1 is inserted into the sliding entrance 241, and the elastic sheet is just buckled to the recessed portion of the last elastic module 1.

A structure of releasing the position-limiting structure is that a side of the elastic sheet facing away from the base sliding surface 213 of the first base 21 or the second base 22 comprises a pressing portion 214 for pushing the position-limiting structure out of the recessed portion to release the position limitation of the last elastic module 1.

Similarly, the connecting base 2 provided in the second embodiment also can be folded and unfolded, just like the connecting base 2 in the first embodiment, as shown in FIGS. 10-12.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover non-substantive modifications of the present disclosure provided they are made based on the concept within the technical scope disclosed in the present disclosure by any technical person skilled in the art.
