Description

Technical Field

[0001] This utility model relates to the field of mattresses, and in particular to a glue-free assembled mattress. Background Technology

[0002] Traditional mattresses require extensive use of glue during manufacturing for one-time assembly, combining different functional and placement layers into a complete mattress. Adjacent layers are glued together. This glue-assembled mattress is environmentally unfriendly, emitting pungent odors during production and use, posing health risks. The odor worsens in warmer temperatures, such as during summer, and even mattresses assembled with environmentally friendly glue may still emit smells. Furthermore, these glue-assembled mattresses lack durability. They are also difficult to disassemble and recycle when disposed of. Utility Model Content

[0003] To address the technical problems associated with the use of glue in existing mattress assembly, such as glue odor, environmental unfriendliness, and difficulty in disassembly and recycling, this utility model provides a glue-free modular mattress. The various parts of the mattress are assembled using a detachable connection method, eliminating the need for glue for fixing. No irritating odors are emitted during production and use, making the mattress environmentally friendly and healthy. It is also easy to disassemble for later mattress recycling and disposal.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A glue-free assembled mattress includes an outer cover and a core assembly and an inner cover assembly wrapped inside it. The outer cover has an openable opening formed by a zipper to accommodate the core assembly and the inner cover assembly. The inner cover assembly continuously surrounds the perimeter of the core assembly. The key feature is that the top and bottom surfaces of the inner cover assembly have detachably connected upper and lower comfort layer assemblies, which cover and limit the movement of the core assembly from both sides. The mattress of this utility model does not require glue for bonding from the outside in, and there is no irritating odor emitted during production, assembly, and use. The mattress is environmentally friendly and healthy, and it is also convenient for disassembly and separation during later recycling and disposal. During assembly, the outermost layer of the mattress is a zippered cover. The inner core components are secured and restrained by the inner cover components that surround it, as well as the upper and lower comfort layer components on its top and bottom sides. This prevents the core components from shifting during the mattress's bending, packaging, or vertical transport, and further improves the mattress's comfort and overall elasticity. The presence of comfort layer components on both the top and bottom sides allows the mattress to be flipped over. The upper and lower comfort layer components are detachably connected to the two sides of the inner cover components.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the inner sleeve assembly includes an annular tubular sleeve and a protective sponge disposed therein, the shape of the protective sponge matches the annular cavity of the tubular sleeve, and the inner hole formed by the tubular sleeve matches the outer contour of the bed core assembly; the upper comfort layer assembly and the lower comfort layer assembly each include a flat upper comfort layer inner sleeve and a lower comfort layer inner sleeve, and both the upper comfort layer inner sleeve and the lower comfort layer inner sleeve are provided with a core pad, and the surfaces of both the upper comfort layer inner sleeve and the lower comfort layer inner sleeve are provided with an opening formed by a zipper to take out and put in the corresponding core pad, and the upper comfort layer inner sleeve and the lower comfort layer inner sleeve are connected to the tubular sleeve along their periphery by a zipper. The inner sleeve assembly consists of a tubular sleeve and an inner edge-protecting foam, with the two shapes matching. The tubular sleeve is annular, and the inner hole of the annular cavity can accommodate the mattress core assembly. The upper and lower comfort layer assemblies are both structures with an outer inner sleeve and an inner core pad. When the core pads of the two comfort layer assemblies have different elasticity, flipping the mattress will provide two different sleeping experiences. The inner sleeve surface has a zipper opening for quick access to the corresponding core pad. The inner sleeve parts of the two comfort layer assemblies are connected to the tubular sleeve by the zipper structure and assembled into a mattress.

[0006] The zipper teeth D and D' on both sides of the zipper connecting the upper comfort layer inner sleeve and the tubular sleeve are respectively located on the bottom periphery of the upper comfort layer inner sleeve and the outer annular periphery of the top surface of the tubular sleeve; the zipper teeth F and F' on both sides of the zipper connecting the lower comfort layer inner sleeve and the tubular sleeve are respectively located on the top periphery of the lower comfort layer inner sleeve and the outer annular periphery of the bottom surface of the tubular sleeve. Both the upper and lower comfort layer inner sleeves adopt a connection structure with zippers installed between their peripheries and the outer annular periphery of the tubular sleeve. When the zipper is closed, the two comfort layers cover the tubular sleeve and the bed core assembly on the upper and lower sides, respectively.

[0007] Both the upper and lower comfort layer components consist of multiple partitioned core pads arranged along the length of the mattress. The inner sleeves of the upper and / or lower comfort layers have several compartments to match the corresponding partitioned core pads. The surfaces of the inner sleeves of the upper and / or lower comfort layers have several zippers that match the compartments, forming openings for inserting and removing the partitioned core pads. Each independent partitioned core pad provides different elasticity support zones within the corresponding comfort layer component, meeting the varying support and elasticity requirements of different body parts and further improving mattress sleep comfort. Each partitioned core pad can be inserted into or removed from a compartment for replacement via the zipper openings.

[0008] The number of partitioned core pads is 3 to 5. The elastic support zones formed by 3 to 5 partitioned core pads can meet the differentiated support elasticity needs of major body parts such as the head, neck, and back.

[0009] The bed core assembly includes a bed core and a bed core cover that encloses it. The bed core cover has a closable opening for inserting and removing the bed core via a zipper C along its bottom edge. The bed core cover also has a sufficiently large opening for inserting or removing the bed core, thanks to the zipper C extending along its bottom edge. The bed core can be a spring core, pocket spring core, foam core, or other commonly used types in existing mattresses.

[0010] The tubular sleeve has a closable opening extending circumferentially for inserting and removing the edge protector sponge. The tubular sleeve inserts or removes the edge protector sponge through the closable opening extending circumferentially. The closable opening can adopt various structures such as common zippers, snaps, or Velcro, as long as it can realize the insertion and removal of the edge protector sponge.

[0011] The tubular sleeve forms a closable opening via a zipper B along the upper edge of its annular inner edge. Using a zipper structure as the closable opening allows for quick and convenient opening and closing, accelerating mattress assembly and improving production efficiency. Furthermore, the zipper closes continuously, providing better positioning of the edge-protecting foam compared to intermittent closures such as snaps and Velcro.

[0012] The tubular sleeve forms a quadrilateral inner hole, and the zipper B extends in the same direction as the sides of the quadrilateral, forming a triangular or quadrilateral zipper structure. The quadrilateral shape of the tubular sleeve accommodates common quadrilateral mattress cores, and the zipper B extends along the direction of each side. The triangular or quadrilateral zipper structure allows for a larger opening of the tubular sleeve exposed within the inner cavity, facilitating assembly with the edge protector foam.

[0013] The outer cover consists of a detachable upper cover and a lower cover joined together by a zipper around their perimeter. Both the upper and lower covers include a base fabric and a continuous edge fabric around the perimeter of the base fabric. Zipper teeth A and A' are located on the perimeters of the edge fabric of the upper cover and the lower cover, respectively. The outer cover is composed of two completely detachable upper and lower covers connected by a zipper, facilitating mattress assembly and disassembly.

[0014] The beneficial technical effects of this utility model are as follows: The mattress is assembled from the inside out, with each part positioned and wrapped by zippers and other combination methods. The entire process does not require the use of glue. There is no irritating odor emitted during the production and use of the mattress. The mattress is environmentally friendly and healthy, and it is also convenient to disassemble and separate it for later recycling. In order to improve the comfort of the mattress, there are comfort layer components with zoned support on the upper and lower sides of the mattress, which can meet the different support needs of users. When the zoned support effect of the comfort layer components on both sides is different, flipping the mattress can also bring different sleeping experiences. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, this utility model is a glue-free assembled mattress, including an outer cover and a mattress core assembly 6 and an inner cover assembly 1 wrapped inside it. The outer cover has an opening that can be opened and closed by a zipper to accommodate the mattress core assembly 6 and the inner cover assembly 1. The inner cover assembly 1 includes an annular tubular sleeve 1-2 and an edge protector sponge 1-1 disposed therein. The shape of the edge protector sponge 1-1 matches the annular cavity of the tubular sleeve 1-2. The inner hole formed by the tubular sleeve 1-2 matches the outer contour of the mattress core assembly 6. The mattress core assembly 6 can be inserted into the inner hole of the tubular sleeve 1-2, so that the inner cover assembly 1 can continuously surround the perimeter of the mattress core assembly 6. The top and bottom surfaces of the inner cover assembly 1 are respectively provided with a detachably connected upper comfort layer assembly 7 and a lower comfort layer assembly 12. The upper comfort layer assembly 7 and the lower comfort layer assembly 12 cover the two sides of the mattress core assembly 6 from the top and bottom sides and limit its position.

[0024] The upper comfort layer assembly 7 and the lower comfort layer assembly 12 each include a flat upper comfort layer inner sleeve 7-1 and a lower comfort layer inner sleeve 12-1, and both the upper comfort layer inner sleeve 7-1 and the lower comfort layer inner sleeve 12-1 are provided with a core pad. The surfaces of the upper comfort layer inner sleeve 7-1 and the lower comfort layer inner sleeve 12-1 are provided with zipper openings for taking out and putting in the corresponding core pads. The upper comfort layer inner sleeve 7-1 and the lower comfort layer inner sleeve 12-1 are respectively connected along the periphery and the tubular sleeve 1-2. The zipper connects the upper comfort layer inner sleeve 7-2 and the tubular sleeve 1-2. The zipper teeth D9 and D'4 on both sides are located on the bottom periphery of the upper comfort layer inner sleeve 7-2 and the outer annular periphery of the top surface of the tubular sleeve 1-2, respectively. The zipper teeth F13 and F'5 on both sides of the lower comfort layer inner sleeve 12-1 and the tubular sleeve 1-2 are located on the top periphery of the lower comfort layer inner sleeve 12-1 and the outer annular periphery of the bottom surface of the tubular sleeve 1-2, respectively.

[0025] During assembly, the outermost layer of the mattress is a zippered cover. The inner core components are secured and restrained by an inner sleeve component surrounding it, as well as upper and lower comfort layer components on both sides. This prevents the core components from shifting during packaging or vertical transport, further enhancing the mattress's comfort and overall elasticity. The presence of comfort layer components on both sides allows the mattress to be flipped over. The upper and lower comfort layer components are detachably connected to the top and bottom of the tubular sleeve via zippers. The entire mattress, from the outside in, requires no glue, and there are no irritating odors during assembly and use. The mattress is environmentally friendly and healthy, and also facilitates disassembly and separation for future recycling.

[0026] Furthermore, the core pads of both the upper comfort layer assembly 7 and the lower comfort layer assembly 12 are composed of multiple partitioned core pads arranged along the length of the mattress. The upper comfort layer inner sleeve 7-1 and the lower comfort layer inner sleeve 12-1 have several cavities matching the corresponding partitioned core pads. The surfaces of the upper comfort layer inner sleeve 7-1 and the lower comfort layer inner sleeve 12-1 have several zippers matching the cavities, forming openings for taking out and placing the partitioned core pads. Alternatively, one of the upper comfort layer assembly and the lower comfort layer assembly may have partitioned core pads, while the other does not.

[0027] The above comfort layer component 7 illustrates the zoned support structure. The number of zoned core pads 7-2 in the upper comfort component 7 is 3 to 5. Figure 4 and Figure 5 The preferred number of partitioned core pads 7-2 shown is three. The upper comfort layer inner sleeve 7-1 has three compartments arranged along the length of the mattress, matching the partitioned core pads 7-2. Each compartment of the upper comfort layer inner sleeve 7-1 has a zipper E8 forming an opening for inserting or removing the corresponding partitioned core pad 7-2. The three partitioned core pads have different elasticities, which can meet the different support and elasticity needs of different parts of the body, improving sleep feel and comfort, and thus enhancing sleep quality.

[0028] Furthermore, the bed core assembly 6 includes a bed core 6-2 and a bed core cover 6-1 that covers it. The bed core cover 6-1 forms a closable opening structure for taking out and putting in the bed core 6-2 by means of a zipper C6-3 provided along its bottom edge.

[0029] Furthermore, in this embodiment, the tubular sleeve is annular on all four sides and has a rectangular cross-section, such as... Figure 1 The diagram uses dashed structural line 15 to illustrate the cross-section of the inner cavity of the tubular sleeve. The shape of the edge protector sponge 1-1 matches the annular cavity of the tubular sleeve 1-2. The tubular sleeve 1-2 has a closable opening extending circumferentially to allow the edge protector sponge 1-1 to be placed in and out. The quadrilateral inner hole formed by the tubular sleeve 1-2 matches the outer contour of the bed core assembly 6. The closable opening is a zipper B3 provided along the upper edge of the annular inner edge of the tubular sleeve 1-2. The zipper B3 extends in the same direction as the side length of the quadrilateral, forming a triangular or quadrilateral zipper structure. In this embodiment, a quadrilateral zipper is preferred, that is, there is an integral zipper B3 on the four sides of the tubular sleeve. Unzipping the zipper B3 allows the edge protector sponge 1-1 shown in the figure to be placed in. The edge protector sponge can be... Figure 1 The diagram shows a quadrilateral frame formed by bending a long sponge strip multiple times, or as shown in Figure 2, four independent sponge strips are placed close together inside a tubular sleeve and zipped up with zipper B3 for shaping.

[0030] Furthermore, the outer cover is composed of a separable upper outer cover 10-1 and a lower outer cover 10-2 connected by a zipper around the perimeter. Both the upper outer cover 10-1 and the lower outer cover 10-2 include a base fabric and a continuous edge fabric around the perimeter of the base fabric. The zipper teeth A11 and A'14 on both sides are respectively located around the edge fabric of the upper outer cover 10-1 and the edge fabric of the lower outer cover 10-2. The two completely separable upper and lower outer covers are connected by a zipper, which facilitates the assembly and disassembly of the mattress.
