Soft cushion layer connection structure of elastic cushion and mattress

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the basis of the Chinese patent application filed with the State Intellectual Property Office of China on December 14, 2023, with application number: 202311728049.4, and the name of the invention: "A soft cushion layer connection structure and mattress for an elastic pad", and claims its priority. 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 a cushion or mattress for furniture. Background Art

[0004] A cushion is a pillow-like support, also known as a "cushion," and is found in a variety of household items, including mattresses and sofas. An elastic pad is typically placed underneath the cushion to provide elastic support. The elastic pad and cushion typically form a composite structure, particularly in a spring bed. This structure consists of a spring base and a cushion cover that wraps around the spring base. The cushion cover is typically secured by sewing or gluing, forming a non-detachable composite spring bed.

[0005] In order to meet the hygiene requirements of the cushion, a mask is usually covered on the cushion of the composite spring bed during use to meet the needs of daily cleaning. However, even if the outer mask is cleaned after long-term use of a cushion, the stains that penetrate into the cushion through the mask cannot be cleaned, and long-term use still poses a hygiene risk.

[0006] Under the existing technology, the cushion cover is changed to an open structure with a continuous zipper to separate the spring cushion layer and the cover during cleaning. However, most spring cushion layers are integrated, especially the spring cushion layers of mattresses, which are large and bulky. This makes it very inconvenient to remove the cover. The cumbersome disassembly and assembly will directly affect the number of times the cover is cleaned daily, and the problem of difficulty in cleaning still exists.

[0007] Therefore, it is necessary to improve the connection design between the cushion layers so that it is not affected by the size of the spring cushion layer, and even there is no need to move the spring cushion layer. Through the reasonable setting of the outer cover, the overall cushion can be conveniently disassembled and assembled and easier to clean. Summary of the Invention

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 1 to 6 , this embodiment provides a connection structure of a cushion layer 2 of an elastic pad, including a spring core composed of a spring module 1 and a cushion layer 2 laid on the spring core.

[0099] The spring module 1 is composed of several springs 11 arranged in a staggered or array pattern. The springs 11 referred to here are individual, pre-compressed springs 11 wrapped in a cloth bag or other flexible material. Adjacent springs 11 are connected by connectors 3 or by connecting portions extending from the flexible material. In this embodiment, the spring module 1 is connected by connectors 3 to form independent springs 11. Adjacent springs 11 provide independent elasticity, with minimal interaction. Mutual traction does not affect the independent elasticity of adjacent springs. A staggered or array arrangement achieves a dense arrangement of springs 11 within the elastic pad.

[0100] Specifically, adjacent springs 11 are connected by a connecting piece 3 at any position of the spring 11 except the upper end. The upper end of the spring 11 is not constrained by the connecting piece 3, and an elastic force-bearing surface is formed with the upper end, so that each spring 11 becomes a whole without the need for a rigid frame. At the same time, the independence of each spring 11 is not affected or is less affected, and a thick sponge layer or other soft pad is not required, so the overall elasticity of the elastic pad can be achieved.

[0101] The spring module 1 formed by connecting in this structure, after forming the spring core, does not need a thick layer of sponge like the traditional spring mattress to make it integral. It only needs to add a flexible cushion layer 2 on the elastic pad, which can be made of duck down, goose down, or latex, with a thickness not exceeding 10 cm, generally 5-6 cm, and can be used as a spring mattress 5.

[0102] The connecting member 3 described in this embodiment can be a cloth bag or other flexible material that is sleeved on the spring 11. A connecting portion is provided on the connecting member 3, and adjacent connecting portions are connected by mutual buckling or staggered engagement or by overlapping a third member.

[0103] The mattress 5 is constructed using the spring modules 1 provided in this embodiment. Adjacent springs 11 in the spring modules 1 are connected by connecting portions around the perimeter of the connectors 3 and arranged in a staggered arrangement. The connectors 3 of several springs 11 located on the periphery of the spring modules 1 are provided with perforations 32. Multiple spring modules 1 are combined to form the spring cushion of the mattress 5. A fixing strap 4 is passed through the perforations 32, circumferentially securing the spring modules 1 and their internal springs 11 in series, forming a tight spring cushion. In a staggered spring array, the springs at both ends are not neatly arranged. In this embodiment, irregularly shaped springs are used to compensate for this, ensuring that the springs at the end surfaces are aligned.

[0104] A soft cushion layer 2 is laid on the formed spring cushion layer to form a complete flexible cushion. The soft cushion layer 2 is detachably connected to the spring core formed by the spring module 1. The soft cushion layer 2 is laid on top of or above and around the spring module 1 to partially cover or semi-cover the spring module 1, leaving the bottom of the spring module 1 uncovered. When removing and cleaning the soft cushion layer 2, the operation can be completed without lifting the spring cushion layer, making removal and replacement convenient.

[0105] Specifically, in this embodiment, the four sides of the cushion layer 2 include side edges 21, and a plurality of buckle positions 22 are provided on the side edges 21. Buckle points 31 are provided on the connecting member 3 on the outer peripheral side of the spring module 1 corresponding to the buckle positions 22; the buckle positions 22 and the buckle points 31 are buckled together to enable the cushion layer 2 to be selectively covered or removed from the spring module 1.

[0106] The buckle position 22 adopts an ear-type structure design. When the buckle position 22 is buckled with the buckle point 31, the ear-type structure provides the buckle position 22 with a certain tensile elasticity, so as to achieve a perfect buckle connection with the buckle point 31. After the buckle connection, the deformation forms a certain tensile force, which further pre-tightens the cushion layer 2 to form a covering effect, thereby avoiding the cushion layer 2 from moving during use.

[0107] In this example, the buckle positions 22 are arranged at intervals of 1-3 springs 11, so as to perfectly cover the spring module 1 and ensure that the buckle receiving force is balanced, so that the buckle does not warp or curl.

[0108] It should be noted that the side edges 21 set on the four sides of the cushion layer 2 can be replaced with pull strips, which are also elastic and serve to pre-tighten the cushion layer 2 and fasten it to the spring module 1. The side edges 21 or pull strips involved in this embodiment are not limited to the structure involved in this embodiment, and can be replaced with elastic drawstrings, pull ropes, etc. as equivalent alternative structures.

[0109] The first embodiment is shown in FIG4 .

[0110] The four sides of the cushion layer 2 include pull strips 21, and the ends of the pull strips 21 are buckle positions 22. A female buckle 311 or a male buckle 221 of a snap button is set at the buckle position 22, and a male buckle 221 or a female buckle 311 of a snap button is correspondingly provided on the side of the corresponding connecting member 3 on the outer peripheral side of the spring module 1.

[0111] The second embodiment is shown in FIG5 .

[0112] The four sides of the cushion layer 2 are provided with side edges 21, and a button 312 or a buttonhole 222 is provided on the ear-type buckle position 22 extending from the side edge 21, and a buttonhole 222 or a button 312 in a snap button is fixed on the side of the corresponding connecting member 3 on the outer peripheral side of the spring module 1. The style design of the button 312 can be used to decorate or beautify the mattress 5 while playing a connecting and fixing role.

[0113] The third embodiment is shown in FIG6 .

[0114] Pull strips 21 are provided on the four sides of the cushion layer 2 , and the ends of the pull strips 21 are buckles 22 . In this embodiment, the buckles are rectangular frames 223 . Corresponding hooks 313 are provided between two adjacent connectors 3 on the outer periphery of the spring module 1 .

[0115] The fourth embodiment is shown in Figures 7-11.

[0116] The difference of this embodiment is that the notch 3141 of the cavity 314 of the buckle point 31 is rotatable, the buckle position 22 is placed in the buckle point 31 , and the buckle point 31 rotates to lock the buckle position 22 .

[0117] The specific structure is as follows: the four sides of the cushion layer 2 include pull strips 21, the ends of the pull strips 21 are buckles 22, and the buckles 22 are provided with protrusions 224 and annular grooves 225 extending from the protrusions 224 to the main body; and the corresponding buckle points 31 on the end surface of the corresponding connecting member 3 on the outer peripheral side of the spring module 1 are provided with a cavity 314 for accommodating the protrusion 224, a notch 3141 for accommodating the annular groove 225, and an opening 3142 passing through the cavity 314 and the notch 3141; the protrusion 224 enters the cavity 314 through the opening 3142; a rotating ring 315 is sleeved on the outside of the cavity 314, and the rotating ring 315 is provided with a ring mouth 3151 adapted to the opening 3142; the rotating ring 315 is rotated so that the opening 3142 and the ring mouth 3151 are relative or staggered, which is used to unlock or lock the protrusion 224.

[0118] In terms of structural setting, the soft cushion layer 2 is further fixed on the spring pad by rotation locking, so as to avoid the soft cushion layer 2 and the spring pad from separating and sliding during use.

[0119] The connector 3 with the buckle point 31 is also used to connect multiple springs 11 to form a spring pad. The connector 3 is used as a third piece to overlap with the buckle position 22 set on the spring 11. The connector 3 is a connector on the outer periphery of the spring module. As shown in Figure 9, the connector 3 has three notches 3141, which respectively connect the pull rod 21 and the springs 11 adjacent to each other on both sides. The spring buckle positions 22 are set on the side of the spring 11, and the buckle positions 22 are evenly spaced along the circumference of the spring 11 on the four sides. The connector 3 is used to overlap the springs 11 on all sides. The buckle positions 22 on each side of the spring 11 have the same structure. During assembly, there is no restriction on the buckle direction. The buckle positions in any direction can be spliced, which is simple and convenient.

[0120] The fifth embodiment is shown in Figures 12-15.

[0121] This embodiment provides that buckle positions 22 and buckle points 31 are arranged at intervals on the side connector 3 of the spring 11, and the buckle positions 22 on the cushion layer are buckled to the buckle points 31 of the spring 11 at the edge of the spring module 1. The specific structure is as follows: the four sides of the cushion layer 2 include a pull strip 21, and the pull strip is provided with a plurality of buckle positions 22, and each buckle position 22 is provided with a protrusion 224 and an annular groove 225 extending from the protrusion 224 to the main body; and the corresponding buckle point 31 on the end surface of the corresponding connector 3 on the outer peripheral side of the spring module 1 is provided with a cavity 314 for accommodating the protrusion 224 and a notch for accommodating the annular groove 225; the notch is constructed to allow the protrusion 224 to enter the cavity 314, and a sliding member 316 is installed on the outside of the cavity 314. The sliding member 316 is provided with notches with different cross-sections at the top and bottom. The notch at the bottom is an insertion opening 3161, the size of which is adapted to the insertion of the protrusion 224. The notch at the top is a locking opening 3162, the notch of which is smaller than the cross-section of the protrusion 224. When buckled, the insertion opening 3161 connects to the chamber 314, and the buckling protrusion 224 is inserted into the chamber 314 through the insertion opening 3161. Then, the sliding member 316 is pressed down, and the locking opening 3162 moves down and is stuck on the rear end annular groove 225 of the protrusion 224, and the pull bar protrusion 224 is confined within the locking opening 3162. In terms of structural setting, the pressing and locking method is further used to better fix the cushion layer 2 on the spring pad, preventing the cushion layer 2 from separating from the spring pad and slipping during use.

[0122] The connector 3 with the buckle point 31 is also used to connect multiple springs 11 to form a spring pad. The connector 3 is mounted on the waist of the spring 11 and is connected through the corresponding buckle positions 22 and buckle points 31 on two adjacent connectors 3.

[0123] In this embodiment, in order to further facilitate the splicing between the spring pad formed between the springs 11 and the cushion layer 2,

[0124] A limit member 317 is provided between the chamber 314 and the sliding member 316 for limiting the sliding member 316 in the unlocked position. The limit member 317 can be rotated while ensuring that the buckle point 31 is in the unlocked position, thereby saving the step of adjusting the locking or unlocking state of the buckle point 31 during splicing.

[0125] The limiting member 317 includes a circular protrusion 3171 arranged on the outer wall of the chamber 314 and a groove 3172 arranged on the sliding member 316 corresponding to the circular protrusion 3171 (as shown in Figure 15); when the sliding member 316 slides upward to the unlocking position (as shown in Figure 13), the groove 3172 and the circular protrusion 224 are interference fit, so that the interference fit increases the friction between the groove 3172 and the circular protrusion 224, and the friction force is used to maintain the sliding member 316 in the unlocking position.

[0126] The sixth embodiment is shown in Figures 16-20.

[0127] The difference of this embodiment is that the buckle position 22 is placed in the buckle point 31 and partially passes through the buckle point 31, so that the buckle position 22 is locked in the buckle point 31 by rotating through the passing portion.

[0128] The specific structure is as follows: the cushion layer 2 includes pull strips 21 on all four sides, and the end of the pull strips 21 is a buckle 22, which includes a clamping member 226 and a rotating member 227 that can rotate relative to the clamping member 226; the connecting member 3 is provided with four locking slots 318; the buckle 22 is provided with the rotating member 227 and the clamping member 226 in sequence along the insertion direction, and the rotating member 227 is rotated to form an offset with the clamping slot 318, which is used to lock the clamping member 226 in the clamping slot 318. The seventh embodiment is shown in Figures 21-23.

[0129] This embodiment provides that the four sides of the cushion layer 2 include pull strips 21, the end of the pull strips 21 is a buckle position 22, and at least one elastic clip 228 is provided on the buckle position 22; and at least one clip 319 is provided on the corresponding buckle point 31 on the end face of the corresponding connecting member 3 on the outer peripheral side of the spring module 1; when the buckle position 22 enters the buckle point 31 to a certain distance, the elastic clip 228 and the clip 319 are buckled and fixed.

[0130] In this embodiment, the buckle position 22 is a rectangular plug-in component, and two elastic clips 228 are set on both sides of the rectangular plug-in component, a vertical slide groove is set on the buckle point 31, and two latches 319 are set on the two sliding side walls of the slide groove. When the rectangular plug-in component is inserted vertically downward along the sliding wall of the slide groove, it is inserted until the elastic clip 228 is aligned with the latch 319. At this time, the elastic clip 228 pops out and is stuck on the latch 319, forming a sliding limit for the rectangular connector, thereby realizing the buckling connection and fixation of the buckle position 22 and the buckle point 31.

[0131] Furthermore, the buckle point 31 is provided with a button 3191 at the locking position 319. Pressing the button 3191 inward causes the elastic clip 228 to retract and release the engagement with the locking position 319. To unlock, the buckle can be released by simply pressing the button 3191 on the locking position 319 to retract the elastic clip 228.

[0132] The eighth embodiment is shown in Figures 24-26.

[0133] This embodiment provides that the four sides of the cushion layer 2 include pull strips 21, the end of the pull strips 21 is a buckle position 22, and at least one latch position 319 is set on the buckle position 22; and at least one elastic clip 228 is set on the corresponding buckle point 31 on the end face of the corresponding connecting member 3 on the outer peripheral side of the spring module 1; when the buckle point 31 enters the buckle position 22 to a certain distance, the elastic clip 228 and the latch position 319 are buckled and fixed.

[0134] In this embodiment, the buckle position 22 is a rectangular plug-in component, which is laterally provided with a card slot 318. An elastic card 228 is provided on the corresponding buckle point 31 on the end face of the corresponding connecting component 3 on the outer peripheral side of the spring module 1, and a card position 319 is provided on the buckle position 22. When the buckle point 31 is inserted into the card slot 318 laterally, it is inserted until the elastic card 228 is aligned with the card position 319. At this time, the elastic card 228 pops out and is stuck on the card position 319, forming an insertion limit for the rectangular plug-in component, thereby realizing the buckling connection and fixation of the buckle position 22 and the buckle point 31.

[0135] Furthermore, the buckle 22 is provided with a button 3191 at the locking position 319. Pressing the button 3191 inward causes the elastic clip 228 to retract and release the engagement with the locking position 319. To unlock, the buckle can be released by simply pressing the button 3191 on the locking position 319 to retract the elastic clip 228.

[0136] The ninth embodiment is shown in Figures 27-32.

[0137] This embodiment provides that the four sides of the cushion layer 2 include a pull strip 21, the end of the pull strip 21 is a buckle position 22, and a buckle 23 is provided on the buckle position 22; and a vertical bayonet 33 is provided on the corresponding buckle point 31 on the end surface of the corresponding connecting member 3 on the outer peripheral side of the spring module 1; the buckle 23 includes an elastic clamping point 231 and an elastic member 234 with the clamping point 231 provided at the front end; the clamping point 231 has a slope 232 and a step surface 233, and the clamping point 231 forms an extrusion effect with the bayonet 33 with the slope 232, and the elastic member 234 is deformed to allow the clamping point 231 to enter the bayonet 33; when the slope 232 is misaligned with the bayonet 33 and is stuck in the bayonet 33, the step surface 233 is pressed against the inner end surface of the bayonet 33 to form a locking position.

[0138] Specifically, the engagement point 231 is divided into a first engagement point 2311 and a second engagement point 2312. The first engagement point 2311 and the second engagement point 2312 are arranged relative to each other with a predetermined interval 2313. This interval 2313 is used to accommodate the movement of the engagement point 231, thereby allowing the elastic member 234 to have an elastic deformation. The inclined surfaces 232 of the first and second engagement points 2311, 2312 are arranged in opposite directions. When the engagement point 231 exerts pressure on the engagement opening 33 with its inclined surfaces 232, the first and second engagement points 2311, 2312 move closer together due to the compressive force, thereby yielding. When an external force is applied inward to compress the lever arms of the elastic member 234 corresponding to the first and second engagement points 2311, 2312, the stepped surface 233 is released from contact with the engagement opening 33, thereby disengaging the engagement point 231 from the engagement opening 33.

When an external force is applied to the outside of the clamping point 231 , the U-shaped or V-shaped structure 2314 is deformed, and the clamping point 231 can be separated from the clamping port 33 .

[0142] The eleventh embodiment is shown in Figures 38-42.

[0144] Specifically, the engagement point 231 is divided into a first engagement point 2311 and a second engagement point 2312. The first engagement point 2311 and the second engagement point 2312 are arranged relative to each other with a predetermined interval 2313.

The inclined surfaces 232 of the first and second engagement points 2311, 2312 are arranged relative to each other. When the engagement point 231 exerts pressure on the engagement opening 33 through the inclined surfaces 232, the first and second engagement points 2311, 2312 move away from each other due to the compressive force. When the lever arms of the elastic member 234 corresponding to the first and second engagement points 2311, 2312 are pulled outward by an external force, the stepped surface 233 is released from contact with the engagement opening 33, thereby disengaging the engagement point 231 from the engagement opening 33.
