Description

Technical Field

[0001] This utility model belongs to the field of home mattress technology, specifically relating to a glue-free dual-sleep feel mattress. Background Technology

[0002] Traditional mattresses typically use a large amount of glue for bonding during the manufacturing process. This not only poses potential threats to the environment and human health but also negatively impacts the mattress's structure and durability. Over time, the glue may accelerate the aging of the mattress's internal materials and even cause the bonded parts to detach, thus shortening the mattress's lifespan. Furthermore, aging materials may release harmful gases, polluting the air quality of the living environment and further affecting the user's health and quality of life.

[0003] Furthermore, when couples share a mattress, their different sleeping preferences often make it difficult for traditional mattresses, with their uniform structure and fixed firmness, to meet individualized sleep needs. Traditional mattresses cannot adjust to a user's body shape, sleeping position, or comfort preferences, limiting the optimization of the sleep experience. In today's context of increasing focus on sleep quality, these issues highlight the shortcomings of traditional mattresses in terms of adaptability and comfort. Utility Model Content

[0004] Based on the aforementioned shortcomings and deficiencies in the existing technology, one of the objectives of this utility model is to at least solve one or more of the aforementioned problems in the existing technology, or to provide a glue-free dual-sleep mattress that meets one or more of the aforementioned needs.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] This invention provides a glue-free dual-feel mattress, comprising a dual-feel adjustment layer and a glue-free core. The dual-feel adjustment layer includes a left support portion and a right support portion, with different firmnesses. It also includes edge protectors and several straps. The glue-free core includes pocket spring assemblies and edge protectors surrounding the pocket spring assemblies. Each pocket spring assembly comprises several pocket springs ultrasonically welded together. The edge protectors are located on the outside of the two pocket spring assemblies, and the straps bind the pocket spring assemblies, restricting their vertical displacement and deformation. This glue-free dual-feel mattress provides left and right support portions with different firmnesses, achieving differentiated sleeping experiences to meet the needs of different users. The edge protector and strap design effectively restricts the deformation of the pocket spring assemblies, improving the mattress's durability and structural stability.

[0007] In a preferred embodiment, the dual sleep comfort adjustment layer further includes adjustment sleeves, which consist of an externally connected left adjustment sleeve and a right adjustment sleeve. The left and right support portions are respectively housed within the left and right adjustment sleeves. The design of the adjustment sleeves facilitates the fixing of support portions with different firmnesses in appropriate positions, while improving the overall durability and maintainability of the dual sleep comfort adjustment layer.

[0008] As a further preferred embodiment, both the left and right adjustment sleeves are equipped with zippers. By opening and closing the zippers, users or production personnel can easily detach and assemble the support parts in the dual sleep comfort adjustment layers, facilitating adjustment of firmness or cleaning and maintenance.

[0009] In one preferred embodiment, the pocket spring assembly includes a left pocket spring assembly and a right pocket spring assembly, with the pocket spring wire diameters of the left and right pocket spring assemblies differing. The different wire diameters of the pocket springs provide differentiated support effects for the left and right sides, which, combined with the dual-sleep adjustment layer, achieves a more customized dual-sleep experience.

[0010] As a preferred embodiment, the glue-free dual-sleep mattress also includes an inner cover, which comprises a top mesh, a bottom mesh, and an inner cover border. The top mesh and bottom mesh are fixed above and below the inner cover border, respectively. The pocket spring assembly and edge protectors are housed within the space formed by the top mesh, bottom mesh, and inner cover border. The protective space provided by the inner cover effectively prevents the glue-free core from shifting or being damaged, while also improving the overall structural integrity and lifespan of the mattress.

[0011] As a further preferred embodiment, the upper and lower mesh fabrics have raised hexagonal patterns, increasing the surface friction of the upper mesh fabric against the dual sleep comfort adjustment layer. The raised patterns enhance the friction of the upper mesh fabric, preventing slippage of the dual sleep comfort adjustment layer and thus ensuring the stability and consistency of the sleep comfort area.

[0012] In a preferred embodiment, the upper fabric of the top layer is one or more of moisture-wicking fibers, bamboo fibers, and Tencel fibers.

[0013] In one preferred embodiment, the edge protector includes four edge strips, which are tenoned together to form a closed rectangle. This tenon-and-mortise edge protector design eliminates the need for glue, enhancing frame stability while ensuring environmental friendliness and facilitating installation and disassembly.

[0014] As a further preferred embodiment, the edge protector also includes a corner fixing sleeve, which is fitted onto the tenon joint of two adjacent edge protector strips.

[0015] As a further preferred embodiment, the edge protector also includes a surrounding steel frame, to which corner fixing sleeves are fixed. The corner fixing sleeves enhance the stability of the tenon joint, prevent the edge protector structure from loosening, and further improve the overall stability and safety of the mattress.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model of a glue-free dual-sleep mattress uses ultrasonic welding to weld the pocket springs into one piece, so that the core can be connected into one piece without glue. Based on the glue-free core, this utility model of a glue-free dual-sleep mattress also has different firmnesses for the left and right support parts in the softness and firmness adjustment part, so that the support strength of the left and right sides of the mattress is different, which can provide different sleeping feelings for couples.

[0028] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to aid in understanding exemplary embodiments of the present invention as defined by the claims and their equivalents. It includes various specific details to aid understanding, but these are to be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, to make the specification clearer and more concise, detailed descriptions of functions and structures well known in the art will be omitted.

[0029] Example 1

[0030] This embodiment discloses a glue-free dual-sleep feel mattress, such as... Figure 1 As shown, the mattress includes a top layer 1, a dual-sleep-feel adjustment layer 2, a non-adhesive core 3, a bottom layer 5, and a perimeter 4. Specifically, the non-adhesive core 3 is located inside the mattress, the dual-sleep-feel adjustment layer 2 is located above the non-adhesive core 3, and the perimeter 4 surrounds the non-adhesive core 3. The top layer 1 and the bottom layer 5 cover the top and bottom of the mattress, respectively, sandwiching the dual-sleep-feel adjustment layer 2 and the non-adhesive core 3 between the top layer 1 and the bottom layer 5.

[0031] The upper layer 1 is made of one or more of the following: moisture-wicking fibers, bamboo fibers, and Tencel fibers, providing a good sleeping feel and having a breathable and moisture-wicking effect.

[0032] See Figure 2 The glue-free core 3 consists of a pocket spring assembly 301 and a protective edge 302 surrounding the pocket spring assembly 301. The pocket spring assembly 301 is connected by ultrasonic welding. Specifically, the structure of the pocket spring assembly 301 is described in [reference needed]. Figure 3 Each pocket spring 3011 includes a bag body and a spring inserted into the bag body. Two sheet-like welded portions 3012 extend vertically from both sides of the bag body, and these two welded portions 3012 are symmetrically arranged. Multiple pocket springs 3011 are arranged in a straight line and staggered at two different angles, so that the welded portions 3012 of adjacent pocket springs 3011 are alternately attached to the front and rear of the pocket spring string, respectively. Then, ultrasonic welding is used to connect the attached welded portions 3012 together to form a single pocket spring string.

[0033] Multiple bagged springs strung together Figure 3The pocket springs are arranged side-by-side, with the welded portions 3012 of two adjacent pocket spring strings touching. Since the pocket springs 3011 are connected in two alternating angles to form pocket spring strings, and each has a welded portion 3012 at both the front and back, each pocket spring string has a welded portion 3012 touching with its adjacent pocket spring strings. By using ultrasonic welding to weld the welded portions 3012 of adjacent pocket spring strings together, multiple pocket spring strings can be combined into a rectangular pocket spring assembly without adhesive bonding.

[0034] See Figure 2 , Figure 4 and Figure 5 The glue-free dual-sleep mattress of this embodiment is also provided with straps 303 arranged in two crisscross directions, and the edge protector 302 also includes a rim steel 3021 surrounding the pocket spring assembly 301.

[0035] Specifically, the edging steel 3021 has two layers, upper and lower. Both the upper and lower layers of the edging steel 3021 have straps 303 arranged crisscrossing in two directions and secured with nails 3031. A certain interval is maintained between the upper and lower layers of straps 303, and the pocket spring assembly 301 is sandwiched between the two layers of straps 303. By binding the pocket spring assembly 301 with the upper and lower layers of straps, the displacement and deformation of the pocket spring assembly 301 are restricted, thereby preventing deformation or misalignment of the spring due to long-term use.

[0036] The dual-sleep-feel adjustment layer 2 is designed with different firmness levels in the left and right zones, thus providing different sleeping sensations for the left and right sides of the mattress.

[0037] The structure of the dual sleep adjustment layer 2 in this embodiment is shown below. Figure 1 and Figure 3 The dual-sleep adjustment layer 2 consists of an adjustment layer cover 201, a left support part 202, and a right support part 203. The adjustment layer cover 201 is divided into a left adjustment layer cover and a right adjustment layer cover.

[0038] The left support portion 202 and the right support portion 203 can achieve different indentation hardness by using the same or different materials, such as sponge, latex, 3D materials, and air fibers. When using different materials, the different materials can be used to create different indentation hardnesses for the left support portion 202 and the right support portion 203. When using the same material, such as both being sponge, sponges with different indentation hardnesses can be used to create different indentation hardnesses for the left support portion 202 and the right support portion 203. The different indentation hardnesses of the left support portion 202 and the right support portion 203 allow the dual sleep comfort adjustment layer 2 to provide different support sensations for the left and right users, such as providing a firmer support sensation for men and a softer support sensation for women.

[0039] The inner edges of the left and right adjustment sleeves are connected, and both have inward-facing openings that are opened and closed by zippers. When the openings are opened, the left support portion 202 and the right support portion 203 can be inserted into the left and right adjustment sleeves respectively from the middle of the adjustment sleeve 201. The left support portion 202 and the right support portion 203 have different indentation hardness, and when the left support portion 202 and the right support portion 203 are inserted into the adjustment sleeve 201, they create distinct left and right sleeping sensations.

[0040] This utility model of a glue-free dual-sleep-feel mattress uses ultrasonic welding to weld the pocket springs into one piece, so that the core can be connected into one piece without glue. Based on the glue-free core 3, this utility model of a glue-free dual-sleep-feel mattress also sets up left and right support parts 202 and 203 with different firmness in the softness and firmness adjustment part 2, so that the support strength on the left and right sides of the mattress is different, which can provide different sleeping feelings for couples.

[0041] In this embodiment, a surface adjustment layer is also provided above the dual sleep comfort adjustment layer 2. The surface adjustment layer is a board with a certain indentation hardness, which is used to buffer and adjust the boundary between the left and right sleep comfort zones of the mattress, so as to avoid the user's perception of too obvious hardness change due to sudden changes in hardness on both sides.

[0042] Example 2

[0043] This embodiment provides a glue-free dual-sleep mattress. Unlike other embodiments, in the glue-free core 3, the pocket spring assembly 301 is divided into left and right parts, with the pocket springs on the left and right having different wire diameters. In this embodiment, the left pocket spring has a larger wire diameter, giving each spring a higher elastic coefficient and resulting in less deformation under the same pressure.

[0044] By differentiating the wire diameter of the pocket springs in the left and right parts, the left and right parts of the glue-free core 3 will deform differently when facing the same pressure. This, combined with the different firmness of the left and right sides of the dual sleep comfort adjustment layer 2, further creates two different sleep comforts that are both comfortable and distinct, satisfying the individual needs of couples for mattress firmness when sleeping together.

[0045] Example 3

[0046] This embodiment provides a glue-free dual-sleep mattress, which differs from other embodiments in that it includes an inner sleeve component 6. For example... Figure 7As shown, the inner sleeve 6 includes a top mesh 601, a bottom mesh 602, and an inner sleeve edging 603, with a cutout in the center of the inner sleeve edging 603. The edge of the top mesh 601 is sewn to the edge of the cutout on the upper surface of the inner sleeve edging 603, and the edge of the bottom mesh 602 is sewn to the edge of the cutout on the lower surface of the inner sleeve edging 603. The adhesive-free core 3 is inserted into the inner sleeve 6, which is composed of the top mesh 601, the bottom mesh 602, and the inner sleeve edging 603. The dual sleep comfort adjustment layer 2 is placed on top of the inner sleeve 6, and both are inserted into the accommodating space enclosed by the upper layer 1, the lower layer 5, and the edging 4.

[0047] The top mesh 601 and bottom mesh 602 are made of mesh fabric with hexagonal holes cut out. The edges of each hexagonal hole protrude upwards, forming a textured surface with high friction. These are located on the upper and lower surfaces of the inner cover 6, respectively. The inner cover 6 not only provides protection for the internal non-adhesive core 3, but also utilizes the high-friction texture of the top mesh 601 to apply greater friction to the dual sleep comfort adjustment layer 2, preventing it from slipping and further improving the overall stability of the mattress.

[0048] Example 4

[0049] The glue-free dual-sleep mattress of this embodiment differs from other embodiments in that the structure of the glue-free core 3 has been improved. Please refer to [link / reference]. Figure 5 and Figure 6 The edge protector of the glue-free dual-sleep mattress in this embodiment consists of four edge protectors, which are connected end to end at a 90-degree angle to form a closed rectangular edge protector 302. The ends of adjacent edge protectors are tenoned, so that the joints of the edge protectors do not require glue.

[0050] A middle fixing sleeve 305 is fixed on the edge guard 302 at intervals. The middle fixing sleeve 305 wraps around the edge guard 302 from the outside and is fixed to the edging steel 3021 by the nail gun 3051, thus wrapping the edge guard 302 and restricting the edge guard 302 around the edging steel 3021.

[0051] A corner fixing sleeve 304 is provided on the edge guard 302. The corner fixing sleeve 304 is fitted onto the tenon joint of two adjacent edge guard strips. Specifically, the middle part of the corner fixing sleeve 304 is bent into a 90-degree angle, and its two sides are fixed to the edging steel 3021 with nails. The corner fixing sleeve 304 is fastened to the outside of the edge guard 302, restricting the joint of two adjacent edge guard strips to the outside of the corner of the edging steel 3021, so that the edge guard 302 surrounds and fits tightly against the edging steel 3021, forming an outer frame that protects the edging steel 3021.

[0052] The above description is merely an exemplary embodiment of this disclosure and should not be construed as limiting the scope of this disclosure. Any equivalent changes and modifications made in accordance with the teachings of this disclosure shall still fall within the scope of this disclosure. Other embodiments of this disclosure will be readily apparent to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This invention is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not described herein. The specification and embodiments are to be considered exemplary only, and the scope and spirit of this disclosure are defined by the claims.
