[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims: On December 14, 2023, the application number of the invention to the State Intellectual Property Office of China is: 2023117205493, and the name of the invention is: "A resilient pad for furniture". The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The present invention relates to the field of furniture, in particular to an elastic pad used for furniture. Background Art

[0004] In modern life, mattresses are an essential piece of furniture among people's bedding. As people's daily lives become increasingly stressful, elastic mattresses with elastic components in the middle are becoming increasingly popular, seeking to relax during sleep. Existing mattresses with elastic components often have the soft cushion, elastic component, and base of these elastic pads integrated into one piece. The upper ends of the springs are connected together, causing localized pressure on the elastic pad to also compress the surrounding elastic components. Consequently, existing elastic pads cannot adjust the range of force applied to the elastic components based on the body's posture, making them unable to adapt to the body's curves and provide a more comfortable and comfortable fit. Furthermore, over long-term use, the elastic force of the springs may change, and the pads may also harbor bacteria and mites. The upper cushion and base of the elastic pads are integrally formed with the elastic component, making it impossible to assess the mattress's usage and wear during use. This requires timely cleaning and replacement of the elastic pad components, such as the upper cushion, springs, and base, based on usage and wear, to ensure the pad remains comfortable and soft.

[0091] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0092] The pre-compression spring described in the present invention, as previously applied for by the inventor and in the published documents, includes a top cover, a bottom cover, and a cloth cover or a strap provided between the top cover and the bottom cover. The spring is accommodated in a cavity surrounded by the bottom cover, the bottom cover and the cloth cover or the strap, and the distance between the bottom cover and the top cover is no greater than the height of the spring.

[0093] Example 1

[0094] 1-11 , the present embodiment provides an elastic pad for furniture, comprising a plurality of elastic modules 1, an upper cushion layer 2 above the elastic module 1, and a bottom layer 3 provided below the elastic module 1 for fixing the elastic module 1, wherein the elastic module 1 is composed of a plurality of pre-compressed springs 10; a connecting member 11 is provided in the middle of the pre-compressed spring 10, and adjacent pre-compressed springs 10 are connected by the connecting member 11; the connecting structure on each side of the pre-compressed spring connecting member 11 includes a first connecting structure and a second connecting structure, wherein the first connecting structure and the second connecting structure are adjacently arranged on different sides of the connecting member, and the pre-compressed spring 10 is connected to the bottom layer 3.

[0095] More specifically, in this embodiment, the connector includes a connector base 110, which is divided into four detachable connector base components 110.1, 110.2, 110.3, and 110.4, which are interlocked to form an annular connector 11, which is engaged with the waist of the pre-compression spring 10. A plug-in 111 is provided on two opposite sides of the connector base 110 as a first connecting structure, and a socket 112 is provided on the other two opposite sides of the connector base as a second connecting structure. A protrusion 111.1 is provided above the plug-in 111 as a locking structure, and a space is provided on the upper wall of the socket 112 to lock the protrusion. When the plug-in 111 is inserted into the socket 112, the protrusion 111.1 is locked into the space. At this time, the plug-in 111 and the socket 112 are limited and cooperated to realize the connection between the pre-compression spring 10.

[0096] The protrusion 111.1 as a locking structure is elastic, and a release piece 112.1 for pushing the protrusion elastically is provided at a position on the upper wall of the socket 112 corresponding to the protrusion 111.1. Pressing the release piece 112.1 drives the protrusion 111.1 to leave the space on the upper wall of the socket 112, releasing the limiting cooperation between the plug-in 111 and the socket 112, and realizing the disassembly of the pre-compression spring 10.

[0097] When connecting the pre-compression spring 10, the plug 111 on the pre-compression spring connector is inserted into the socket 112 of the other pre-compression spring, and the protrusion 111.1 is engaged with the space on the upper wall of the socket 112 to connect the pre-compression spring 10. When removing the pre-compression spring 10, the release member 112.1 is pressed to drive the protrusion 111.1 out of the space on the upper wall of the socket, releasing the restraining fit between the socket 112 and the plug 111, and thus removing the pre-compression spring 10.

[0098] In this embodiment, the pre-compressed spring 10 at the outermost periphery of the elastic module 1 and the pre-compressed spring 10 at the outermost periphery of another elastic module 1 are also connected through the aforementioned male-female connection between the socket 112 and the plug 111. As a simple alternative to this embodiment, the pre-compressed spring 10 at the outermost periphery of the elastic module 1 and the pre-compressed spring 10 at the outermost periphery of another elastic module 1 can also be connected using a lap joint.

[0099] In order to be able to judge the usage and cleanliness of the elastic pad during use, and to clean or replace parts of the elastic pad in time according to the usage, in this embodiment, the upper pad 2 is arranged above the elastic module 1, and the pre-compression spring 10 is exposed to the outside. The elastic pad has an open structure. The user can judge the cleanliness of the elastic pad and the degree of wear of the spring in time with the naked eye during use.

[0100] In order to facilitate users in cleaning and replacing parts of the elastic pad, as shown in Figures 8-11, in this embodiment, a drawstring strip 20 is provided around the upper pad layer 2, and the drawstring strip 20 is connected to the plug-in 111 or the socket 112 on the pre-compressed spring connector 11 at the outermost periphery of the spring core 1 to realize a detachable connection between the upper pad layer 2 and the elastic module 1.

[0101] In this embodiment, the same groove 201 as that on the connecting piece is provided on the buckle strip 20 and is connected to the plug-in 111 on the connecting piece. As a simple replacement of this embodiment, the same protrusion as that on the connecting piece can also be provided on the buckle strip 20 and connected to the groove of the connecting piece.

[0102] In this embodiment, to meet users' varying needs for elastic cushion softness, the upper cushion layer 2 is formed by combining multiple upper cushion layers of varying hardness. Users can select and combine upper cushion layers of varying hardness based on their actual needs and preferences for upper cushion softness to create a cushion layer 2 that suits their needs. The surface of the upper cushion layer 2 can also be made of various materials, such as genuine leather, microfiber, cotton, and wool. As a simple alternative to this embodiment, the upper cushion layer 2 can also be integrally formed.

[0103] Referring to Figures 36-51, in this embodiment, the bottom layer 3 is composed of multiple bottom layer units 30. In order to enable the pre-compression spring 10 to be connected to the bottom layer 3, a positioning protrusion 31 is provided on the bottom layer 3 as a fixing part, and the lower end surface of the pre-compression spring 10 is provided with a concave cavity structure 102.2 that cooperates with the positioning protrusion to limit the position. The positioning protrusion 31 is connected to the concave cavity structure 102.2 on the bottom layer 3 through male and female connections.

[0104] The bottom layer 3 is composed of multiple bottom layer units 30 connected together by a connecting knob 32 to form the size of the elastic module 1. The connecting knob 32 is a circular knob with two symmetrical T-shaped clamping feet 32.1 at its bottom. The edges of the bottom layer units are provided with slide rails 30.1 that are positioned to engage with the T-shaped clamping feet 32.1 of the connecting knob 32. The width of the slide rail 30.1 gradually narrows as the knob is rotated. The two T-shaped clamping feet 32.1 of the connecting knob 32 are respectively inserted into the wide parts of the slide rails 30.1 of two adjacent bottom layer units 30. The handle on the connecting knob 32 is then held and the connecting knob 32 is rotated until the clamping feet 32.1 are restrained by the narrow part of the slide rail 30.1 to connect the adjacent bottom layer units 30.

[0105] As a simple alternative to this embodiment, the bottom layer 3 can also be integrally formed to the size of the elastic module 1. At the same time, since the pre-compressed springs 10 inside the elastic module 1 are interconnected, the positioning protrusions 31 can only be provided on the bottom layer unit 30 on the periphery of the bottom layer 3.

[0106] In this embodiment, the elastic pad is composed of multiple elastic modules 1, and multiple bottom layers 3 connected to the pre-compressed springs 10 are detachably connected through the above-mentioned connecting knob 32 to form a base for connecting the elastic modules 1. This allows the user to select a certain number of elastic modules 1 and detachably connected bottom layers 3 according to actual size requirements to splice and form an elastic pad.

[0107] The size of the bottom unit 30 can be arbitrarily set. One bottom unit 30 can be connected to one pre-compressed spring 10 or multiple pre-compressed springs 10. The bottom layer 3 can be formed by connecting bottom units 30 of different sizes through the connection knob 32, or by connecting bottom units 30 of the same size through the connection knob 32. As a simple alternative to this embodiment, the bottom units 30 and the bottom layers 3 can also be detachably connected by plugging, hinges, etc.

[0108] Specifically, the bottom layer 3 can be formed by splicing a plurality of bottom layer units 30 with 8 seats and a plurality of bottom layer units 30 with 4 seats, or by splicing a plurality of bottom layer units 30 with 5 seats, or by splicing a plurality of bottom layer units 30 with 1 seat and a plurality of bottom layer units 30 with 5 seats. The number of seats on the bottom layer units 30 and the splicing combination are not limited to those mentioned in this embodiment.

[0109] In this embodiment, the bottom layer 3 connected to the pre-compression spring 10 is composed of a rigid substrate, which can be formed of rigid materials such as wood boards, blister boards, etc. As a simple alternative to this embodiment, the bottom layer 3 can also be composed of a flexible substrate.

[0110] Referring to Figures 50-51, in this embodiment, in order to facilitate transportation or handling of the elastic pad after disassembly, the pre-compressed spring can be compressed to a locked state. The height of the spring compressed to the locked state is greatly reduced, and the space occupied is reduced, making transportation and handling convenient.

[0111] More specifically, the pre-compression spring includes a top cover 101 and a bottom cover 102. The top cover 101 is provided with a first latching structure 101.1, and the bottom cover 102 is provided with a second latching structure 102.1. The first latching structure 101.1 and the second latching structure 102.1 are detachably buckled. The bottom cover 102 of the pre-compression spring is provided with a concave cavity structure 102.2 which is limitedly matched with the positioning protrusion on the lower end surface. The bottom cover 102 is the outer cover of the concave cavity structure. On the bottom surface, the second locking structure 102.1 is a convex edge arranged on the outer periphery of the upper end of the pre-compression spring cavity structure 102.2, and is a discontinuous ring; use external force to compress the pre-compression spring 10 until the hook of the first locking structure 101.1 and the convex edge of the second locking structure 102.1 are interlocked to realize the compression of the pre-compression spring, and then use external force and rotate the pre-compression spring 10 to rotate the first locking structure 101.1 away from the second locking structure 102.1 to realize the release of the pre-compression spring.

[0112] Example 2

[0113] 12-20 , the main difference between this embodiment and embodiment 1 is that the plug-in 121 of this embodiment is inserted into the socket 122 from above, i.e., from the length direction of the pre-compression spring, and the socket 122 is provided with an opening in the insertion direction of the plug-in 121 and is also opened in the opposite direction of the pre-compression spring, so that the socket is more elastic, making the fit between the plug-in 121 and the socket 122 tighter.

[0114] The plug 121 and the socket 122 are detachably connected to the connector 120. The connector is divided into two left and right lobed connector assemblies 120.2 and 120.3, each of which has a retaining strip 120.1 at its end. The plug 121 is rectangular and has a slot 121.2 on the end of the plug 121 facing the connector. Inserting the retaining strips 120.1 of the left and right connectors into the slots 121.2 of the plug 121 locks the two lobed connectors 120.2 and 120.3 together to form an annular connector that engages the waist of the pre-compression spring 10. Protrusions 121.1 are provided on both sides or one side of the plug 121 as a locking structure. Release members 122.1 are provided on the two side walls of the socket 122 at positions corresponding to the protrusions 121.1. The release members 122.1 and the two side walls of the socket form a space that can be locked into the protrusions 121.1. Insert the plug 121 vertically into the socket 122, and the protrusions 121.1 engage the spaces on the two side walls of the socket. At this point, the plug 121 and the socket 122 engage in a limited manner to connect the pre-compressed springs. Press the release member 122.1 to push the protrusions 121.1 out of the spaces on the two side walls of the socket to disassemble the two pre-compressed springs 10.

[0115] In this embodiment, as shown in Figures 17-19, the same protrusion 202 as that on the connecting piece is provided on the drawstring strip 20 and is connected to the socket 122 on the connecting piece. As a simple replacement of this embodiment, the same socket as that on the connecting piece of this embodiment can also be provided on the drawstring strip 20 to be connected to the plug-in 121 of the connecting piece.

[0116] Example 3

[0117] 21-31 , the main difference between this embodiment and embodiment 1 is that two opposing sides of a connector 130 are provided with plug-in T-shaped protrusions 131 as a first connecting structure, while two opposing sides of the connector are provided with socket recesses 132. A second connecting structure is formed by vertically movable locking T-shaped protrusion buttons 132.1 mounted on the recesses 132. The connector is divided into two detachable left and right connector components 130.4 and 130.5.

[0118] The two ends of the left and right connecting bases are respectively provided with an insert 130.1 and a socket 130.2. The insert 130.1 of one petal is inserted into the socket 130.2 of the other petal, forming a ring-shaped connecting member that is fixed to the waist of the pre-compressed spring. A protrusion 130.3 is formed at the junction of the two petals of the connecting base, and a slot 132.4 is provided at the end of the recess facing the connecting member. The protrusion 130.3 is inserted into the slot 132.4, thereby fixing the recess 132 to the connecting base 130.

[0119] More specifically, button 132.1 is provided with a locking hole 132.2 corresponding to the recessed hole, and a limiting hole 132.3 having a smaller diameter than the locking hole is provided above the locking hole 132.2. To connect the pre-compression springs 10, the T-shaped protrusion 131 of the pre-compression spring connector is passed through the locking hole 132.2 of the button of the other pre-compression spring and then locked into the recessed hole 132, as shown in Figure 24.

The connector is divided into two detachable lobes 140.1 and 140.2 that interlock to form a ring-shaped connector.

[0123] When connecting pre-compression springs 10, the T-shaped protrusion 141 is inserted into the groove 142 of another pre-compression spring 10 through the knob 142.1. At this time, the T-shaped protrusion 141 and the groove 142 are limited in the horizontal direction; the knob 142.1 is rotated until the T-shaped protrusion 141 and the knob are limited in the vertical direction. At this time, the T-shaped protrusion 141 is locked by the knob 142.1, and the connection between adjacent pre-compression springs 10 is completed. When the pre-compression springs 10 are disassembled, the knob 142.1 is rotated to release the lock on the T-shaped protrusion 141, and the T-shaped protrusion 141 is removed to release the connection between the adjacent pre-compression springs 10.

[0124] In this embodiment, a T-shaped protrusion 203 is provided on the upper cushion layer drawstring strip 20, as shown in Figure 30. The T-shaped protrusion 203 on the drawstring strip is engaged with the groove 142 of the outermost pre-compression spring 10 of the elastic cushion, and then the knob 142.1 is rotated to lock the T-shaped protrusion 203, thereby achieving a detachable connection between the upper cushion layer 2 and the elastic module 1. The remaining steps are the same as those in Example 1 and will not be repeated.
