[0001] Cross-references to related applications

[0002] This application claims priority based on Chinese Patent Application No. 2025201929381, filed on February 7, 2025, entitled "A Spring Component and Elastic Pad", the contents of which are incorporated herein by reference. Technical Field

[0003] This utility model relates to the technical field of furniture spring pads, and more particularly to a spring component and an elastic pad. Background Technology

[0004] Spring mattresses, sofa beds, and other furniture are essential parts of people's lives. Most existing beds and sofa beds are equipped with spring mattresses. Spring mattresses have a certain degree of elasticity, providing support and comfort compared to hard mattresses when people lie on them.

[0005] Current elastic pads are formed by connecting multiple springs together. A common connection method is to have male and female ends on the springs, relying on their interlocking for connection. However, because springs sink under pressure during use, to ensure comfort, they must be connected in both width and height directions. This ensures that when one spring sinks, it pulls down the surrounding springs. Therefore, existing technology sets the male and female ends to have a certain height difference, connecting them along the height of the springs to create a limiting fit in both width and height. However, this connection method requires disassembly by displacing the two connected springs along their height, which requires the user to overcome the spring force, making disassembly quite strenuous.

[0006] Utility Model Content

[0007] The main technical problem to be solved by this utility model is to provide a spring component that does not require moving the spring component along its height direction when installing or disassembling it, thus facilitating user disassembly of the spring component.

[0008] To solve the above-mentioned technical problems, this utility model provides a spring component with a connecting structure. The connecting structure is divided into a male end and a female end, and the male and female ends of two adjacent spring components are connected to each other to connect multiple spring components into a spring module.

[0009] The female end has a slot for the male end to be inserted along the width direction of the spring and for being limited and engaged in the opposite direction of insertion; the male end includes an insertion section for inserting into the slot and a limiting section rotatably connected to the insertion section; the limiting section rotates relative to the insertion section from a first position to a second position under the action of an external force, and when the limiting section is in the second position, the limiting section and the female end are limited and engaged in the height direction of the spring.

[0010] In a preferred embodiment: the limiting segment is disposed on the upper and lower sides of the insertion segment along the height direction of the spring member.

[0011] In a preferred embodiment: the female end is provided with a positioning protrusion, and the male end is provided with a positioning groove that mates with the positioning protrusion; when the limiting segment is in the second position, the positioning protrusion is placed in the positioning groove.

[0012] In a preferred embodiment: the side of the slot facing the male end is an open surface, and the two side walls of the open surface extend in a direction of mutual proximity to form limiting walls; the distance between the two limiting walls is less than the width of the insertion segment, so as to limit the engagement of the insertion segment in the opposite direction of insertion after the insertion segment is inserted into the slot.

[0013] In a preferred embodiment: the connecting structure is a waist ring disposed in the middle of the spring member, and two male ends and two female ends are arranged sequentially at 90° intervals on the side of the waist ring.

[0014] In a preferred embodiment: the spring is an upper and lower connected spring, and the waist ring is connected to the top of the lower spring and the bottom of the upper spring.

[0015] In a preferred embodiment: the upper spring and the lower spring are pre-compressed springs;

[0016] The pre-compression spring includes a spring, a bracket, and a cloth sleeve or webbing on the bracket. The spring is confined within the bracket, and the cloth sleeve or webbing pulls the spring taut, thus pre-compressing the spring.

[0017] This utility model also provides an elastic pad, including a soft pad layer and a spring module; the spring module is formed by connecting multiple spring components as described above through a connecting structure; the soft pad layer is disposed on the upper surface of the spring module.

[0018] In a preferred embodiment: the side of the cushion layer is provided with pull strips spaced circumferentially, and the end of the pull strip away from the cushion layer is connected and fixed to the side of the spring module.

[0019] In a preferred embodiment: the outermost spring in the spring module has a decorative cover on its female end and a cap detachably connected to the decorative cover. The cap and the decorative cover are detachably connected by a connecting post, and a clearance cavity is formed between the cap and the decorative cover for the pull strip to pass through. The short pull strip has a clearance hole corresponding to the position of the connecting post. When the pull strip is placed in the clearance cavity, the connecting post passes through the clearance hole and connects to the decorative cover to fix the short pull strip in the clearance cavity.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This invention provides a spring component with its male end divided into an insertion section and a limiting section. This allows for a limiting fit between the insertion section and the female end along the width direction of the spring component, and a limiting fit between the limiting section and the female end along the height direction. This interconnects multiple spring components in both the width and height directions, ensuring that when one spring component is subjected to force and sinks, it can cause the surrounding spring components to sink as well, guaranteeing a reliable connection. Furthermore, when removing the spring component, only the male and female ends need to be separated along the width direction; there is no need to move the spring component along its height direction, thus eliminating the need to overcome the elastic force of the spring component. This significantly reduces the force and difficulty required for removal, simplifying the user's operation. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. 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 a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0034] Referring to Figures 1-9, this utility model provides a spring component 1, on which a connecting structure 2 is provided; the connecting structure 2 is divided into a male end 21 and a female end 22, and the male ends 21 and female ends 22 of two adjacent spring components 1 are connected to each other to connect multiple spring components 1 into a spring module.

[0035] In this embodiment, two adjacent spring members 1 only need to be connected along the width direction of the spring member 1 to form a limiting fit in both the width and height directions of the spring member 1. This avoids the drawback of the prior art, which requires the two spring members 1 to move relative to each other along the height direction before they can be connected or disassembled. To achieve the above effect, the female end 22 has a slot 221 for the male end 21 to be inserted along the width direction of the spring member 1 and for a limiting fit in the opposite direction of insertion; thus, after the male end 21 is inserted into the female end 22, the male and female ends form a limiting fit in the width direction of the spring member 11.

[0036] To form a limiting fit between the two spring members 1 along the height direction, the male end 21 includes an insertion section 211 for inserting into the slot 221 and a limiting section 212 rotatably connected to the insertion section 211; the limiting section 212 rotates relative to the insertion section 211 from a first position to a second position under the action of an external force, and when the limiting section 212 is in the second position, the limiting section 212 and the female end 22 are limited to fit together along the height direction of the spring member 1.

[0037] The aforementioned spring component 1 divides its male end 21 into an insertion section 211 and a limiting section 212. This allows the insertion section 211 and the female end 22 to form a limiting fit along the width direction of the spring component 1, and the limiting section 212 and the female end 22 to form a limiting fit along the height direction of the spring component 1. This interconnects multiple spring components 1 in both the width and height directions, ensuring that when one spring component 1 is subjected to force and sinks, it can cause the surrounding spring components 1 to sink together, ensuring a reliable connection of the spring components 1. Furthermore, when removing the spring component 1, it is only necessary to separate the male end 21 and the female end 22 along the width direction of the spring component 1; it is not necessary to move the spring component 1 along the height direction, thus eliminating the need to overcome the elastic force of the spring component 1. This greatly reduces the force and difficulty required to remove the spring component 1, making it more convenient for the user.

[0038] Since the spring element 1 has both downward and upward movement, the limiting segment 212 needs to enable adjacent spring elements 1 to move in both downward and upward movements. Therefore, the limiting segment 212 is arranged on the upper and lower sides of the insertion segment 211 along the height direction of the spring element 1. Thus, when the spring element 1 sinks, the upper limiting segment 212 engages with the female end 22; when the spring element 1 rises, the lower limiting segment 212 engages with the female end 22.

[0039] The position change of the limiting segment 212 is achieved by the user applying external force, which can easily lead to the limiting segment 212 not rotating into the correct position. To avoid this problem, the female end 22 is provided with a positioning protrusion 222, and the male end 21 is provided with a positioning groove that mates with the positioning protrusion 222. Thus, when the user applies external force to move the limiting segment 212 to the second position, the positioning protrusion 222 is positioned in the positioning groove. The positioning protrusion 222 and the positioning groove provide a clear indication to the user, allowing the user to accurately rotate the limiting segment 212 to the second position.

[0040] In this embodiment, to achieve a limiting fit between the insertion segment 211 and the slot 221 in the opposite insertion direction, the side of the slot 221 facing the male end 21 is an open surface, and the two side walls of the open surface extend in a direction of mutual proximity to form limiting walls 223; the distance between the two limiting walls 223 is less than the width of the insertion segment 211, so as to limit the fit between the insertion segment 211 and the slot 221 in the opposite insertion direction after the insertion segment 211 is inserted into the slot 221. With the above settings, when the limiting segment 211 is inserted into the slot 221, it first interferes with the limiting wall 223, causing the limiting wall 223 to open outward, expanding the width of the open surface, thereby allowing the insertion segment 211 to be inserted into the slot 221. After the insertion segment 211 is inserted into the slot 221, the interference between the insertion segment 211 and the limiting wall 223 disappears, and the limiting wall 223 retracts inward to reset, thereby achieving a limiting fit between the limiting wall 223 and the insertion segment 211 in the opposite insertion direction.

[0041] Specifically, in this embodiment, the connecting structure 2 is a waist ring located in the middle of the spring member 1. Two male ends 21 and two female ends 22 are arranged sequentially at 90° intervals on the side of the waist ring. In this way, by changing the relative position of two adjacent spring members 1, one of the male ends 21 and one of the female ends 22 of the two adjacent spring members 1 can be aligned, thereby realizing the mutual connection of the two spring members 1.

[0042] The spring element 1 can be a one-piece spring or a spring with upper and lower connections. In this embodiment, it is a spring with upper and lower connections. The corresponding waist ring is connected to the top of the lower spring 11 and the lower end of the upper spring 12. If it is a one-piece spring, then the waist ring can simply be set in the middle of the one-piece spring.

[0043] In order to meet the requirements of comfort, the spring component 1 needs to have a certain degree of stiffness. Therefore, the upper spring 12 and the lower spring 11 are pre-compressed springs. By pre-compressing, the spring component 1 can have a certain degree of stiffness. The stiffness of the spring component 1 can also be adjusted by changing the degree of spring pre-compression, thereby meeting the needs of different users.

[0044] To achieve pre-compression, the pre-compression spring in this embodiment includes a spring, a bracket, and a cloth sleeve or webbing on the bracket. The spring is confined within the bracket, and the cloth sleeve or webbing can tighten the spring to put it in a pre-compressed state.

[0045] This embodiment also provides an elastic pad, including a soft pad layer 3 and a spring module 4; the spring module 4 is formed by connecting multiple spring elements 1 as described above through a connecting structure 2; the soft pad layer 3 is disposed on the upper surface of the spring module 4.

[0046] To secure the cushion layer 3, pull strips 31 are spaced circumferentially along the side of the cushion layer 3. The end of each pull strip 31 away from the cushion layer 3 is connected and fixed to the side of the spring module 4. Specifically, the outermost ring of springs 1 in the spring module 4 has a decorative cover 41 and a cap 42 detachably connected to the decorative cover 41 on its female end 22. The cap 42 and the decorative cover are detachably connected by a connecting post, and a clearance cavity is formed between the cap 42 and the decorative cover 41 for the pull strips 31 to pass through. The short pull strips 31 have clearance holes corresponding to the positions of the connecting posts. When the pull strips 31 are placed in the clearance cavity, the connecting post passes through the clearance holes and connects to the decorative cover 41 to fix the short pull strips 31 in the clearance cavity.

[0047] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model. Industrial applicability

[0048] This invention provides a spring component with its male end divided into an insertion section and a limiting section. This allows for a limiting fit between the insertion section and the female end along the width direction of the spring component, and a limiting fit between the limiting section and the female end along the height direction. This interconnects multiple spring components in both the width and height directions, ensuring that when one spring component is subjected to force and sinks, it can cause the surrounding spring components to sink as well, guaranteeing a reliable connection. Furthermore, when removing the spring component, only the male and female ends need to be separated along the width direction; there is no need to move the spring component along its height direction, thus eliminating the need to overcome the elastic force of the spring component. This significantly reduces the force and difficulty required for removal, facilitating user operation and demonstrating good industrial applicability.
