Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly to a mattress. Background Art

[0002] The existing mattress is of a multi-layer structure, and the projection contours of each layer coincide, so that each layer is assembled by being stacked in sequence. Since the layers are stacked vertically, there is a lack of horizontal limitation between adjacent layers, resulting in the situation that each layer will shift due to horizontal force, which not only causes the vertical misalignment of each layer of the mattress, and then leads to the difference in the support of each area on the top surface of the mattress, affecting the support experience, but also causes the unevenness of the side wall due to the shift of each layer, affecting the aesthetics. Content of the Utility Model

[0003] In order to solve the deficiencies of the existing technology, the utility model provides a mattress, which is provided with a base with an assembly groove, and a support layer and a massage layer are sequentially installed in the assembly groove, playing a role of horizontal limitation on the support layer and the massage layer, not only ensuring the unified support of each area on the top surface of the mattress body, but also ensuring the flatness of the side wall of the mattress body, and improving the use experience.

[0004] The utility model is realized in the following way: A mattress, comprising a mattress body, the mattress body includes a base, a support layer and a massage layer, an upwardly exposed assembly groove is opened in the base, the support layer and the massage layer are sequentially installed in the assembly groove, so that the top surface of the massage layer and the top surface of the base are joined to form a flat supporting surface. By providing a base with an assembly groove, and sequentially installing the support layer and the massage layer in the assembly groove, and the top surface of the massage layer is joined with the peripheral edge of the assembly groove opening to form a flat supporting surface, it not only plays a role of horizontal limitation on the support layer and the massage layer, ensures the unified support of each area on the top surface of the mattress body, but also ensures the flatness of the side wall of the mattress body, and improves the use experience.

[0005] Preferably, the peripheral contours of the support layer and the massage layer match the side wall contours of the assembly groove, so as to reduce the gaps between the support layer and the assembly groove and between the massage layer and the assembly groove. The side walls of the support layer and the massage layer are both matched and attached to the side wall of the assembly groove, effectively reducing the gaps, which not only plays a role of horizontal limitation on the massage layer and the support layer, but also ensures that the top surface of the massage layer and the peripheral edge of the assembly groove opening can be joined to form a flat supporting surface, improving the lying comfort and effectively eliminating the foreign body sensation caused by the gaps.

[0006] Preferably, the sum of the thicknesses of the support layer and the massage layer is the same as the depth of the assembly groove, ensuring that the support layer and the massage layer can completely fill the assembly groove after being installed, and ensuring that the top surface of the massage layer is flush with the peripheral edge of the assembly groove opening and joined to form a flat supporting surface.

[0007] Preferably, the base includes a bottom plate and a sponge edging. The sponge edging is arranged along the peripheral edge of the top surface of the bottom plate and encloses to form the assembly groove. The bottom plate and the sponge edging are processed independently, effectively reducing the processing difficulty and improving the raw material utilization efficiency. The sponge edging is vertically arranged along the peripheral edge of the top surface of the bottom plate, thus enclosing to form the assembly groove, effectively improving the production convenience and further enhancing the assembly efficiency.

[0008] Preferably, the base includes a first outer cover that tightly wraps the bottom plate and the sponge edging to limit the offset between the bottom plate and the sponge edging. The first outer cover tightly wraps the bottom plate and the sponge edging to ensure the relative positions of the bottom plate and the sponge edging are fixed. It also reduces the resistance for the support layer and the massage layer to slide into the assembly groove, effectively improving the assembly convenience and facilitating the disassembly and cleaning of the first outer cover.

[0009] Preferably, the sponge edging is in a square frame shape and includes side edgings and end edgings. A deformation groove is formed at the top edge of the side edging, and a deformation hole is formed in the middle. The deformation groove can provide a deformation space for the top edge of the side edging, and the deformation hole provides a deformation space for the middle part of the side edging, making the top and middle parts of the side edging softer and providing comfortable support for the user sitting on the edge of the mattress.

[0010] Preferably, the support layer is in a cuboid shape and includes a front block, a middle block, and a rear block that are sequentially arranged from front to back. The support layer is lapped on the bottom wall of the assembly groove through a flat bottom surface and supports the massage layer through a flat top surface. The front block, the middle block, and the rear block are sequentially laid from front to back, which can not only form a partition with different support properties so that each body segment of the user can obtain different supports, thereby improving the support comfort, but also make the support layer have a flat top surface to effectively support the massage layer.

[0011] Preferably, the middle block is in a cuboid shape and includes a support bladder group and two support pads. Perforations are provided on the support pads. The support bladder group includes support air bags arranged in a matrix and an air path platform arranged in the middle of the support air bags. The support pads vertically clamp the air path platform and are sleeved on the ends of the support air bags through the perforations. The support pads are vertically stacked and wrap and position the support bladder group. The support bladder group adjusts the softness and hardness by inflating and deflating, making the softness and hardness of the middle block adjustable. The support pads vertically clamp the air path platform and are sleeved on the corresponding support air bags through the perforations, preventing the support bladder group from shifting by clamping the air path platform and guiding the telescopic deformation of the support air bags through the perforations.

[0012] Preferably, the front block is a cuboid-shaped sponge pad, which not only effectively reduces the cost, but also is convenient for processing and assembly and provides effective support for the corresponding body segment of the user.

[0013] Preferably, the rear block is a cuboid-shaped spring pad, which is not only convenient for processing and assembly, but also provides effective support for the corresponding body segment of the user.

[0014] Preferably, the support layer includes a second outer casing that tightly wraps the middle block. The second outer casing tightly wraps the middle block, ensuring the relative positions of the support pad and the support bladder group are fixed, guaranteeing that the support bladder group is tightly clamped by the support pad, and facilitating the disassembly and cleaning of the second outer casing.

[0015] Preferably, the massage layer is in the shape of a cuboid and includes a fixed pad and a massage bladder group provided on the fixed pad. The massage bladder group includes massage air bladders arranged in a matrix, and the massage air bladders form a massage stimulation applied upward through inflation and deflation. The cuboid-shaped massage layer can be fitted into the assembly groove to ensure it fits against the groove wall of the assembly groove. The massage bladder group forms a massage stimulation through inflation and deflation to provide massage services to the user.

[0016] Preferably, the massage layer includes a limit pad provided on the fixed pad, and through holes for the massage air bladders to pass through are provided on the limit pad. The limit pad is sleeved on the massage air bladders through the through holes, which not only plays a role in clamping and positioning the massage bladder group but also guides the expansion and contraction of the massage air bladders to ensure that the massage air bladders generate a massage stimulation vertically upward.

[0017] Preferably, the massage layer includes a third outer casing, an upper pad, and a lower pad. The upper pad, the limit pad, the massage bladder group, the fixed pad, and the lower pad are stacked in sequence from top to bottom and are tightly wrapped by the third outer casing. The third outer casing can tightly wrap the components of each layer inside the massage layer, ensuring the relative positions of each layer are fixed and facilitating the disassembly and cleaning of the third outer casing.

[0018] The beneficial effects of the present utility model: A base with an assembly groove is provided, and the support layer and the massage layer are sequentially inserted into the assembly groove. The top surface of the massage layer and the peripheral edge of the assembly groove opening are joined to form a flat supporting surface, which not only plays a role in horizontally limiting the support layer and the massage layer, ensuring uniform support in each area of the top surface of the pad body, but also ensures that the side wall of the pad body remains flat, improving the user experience.

Specific embodiments

[0027] The following further illustrates the substantial features of the present utility model in conjunction with the description drawings and specific embodiments.

[0028] Embodiment 1:

[0029] This embodiment provides a mattress.

[0030] As Figure 1 shown, the mattress body includes a base 1, a support layer 2, and a massage layer 3. An upwardly open assembly groove 4 is formed in the base 1, and the support layer 2 and the massage layer 3 are sequentially installed in the assembly groove 4 so that the top surface of the massage layer 3 is joined with the top surface of the base 1 to form a flat supporting surface. By providing the base 1 with the assembly groove 4 and sequentially installing the support layer 2 and the massage layer 3 in the assembly groove 4, and joining the top surface of the massage layer 3 with the peripheral edge of the opening of the assembly groove 4 to form a flat supporting surface, it not only plays a role in horizontally limiting the support layer 2 and the massage layer 3, ensuring uniform support in each area of the top surface of the mattress body, but also ensures that the side wall of the mattress body remains flat, improving the use experience.

[0031] In this embodiment, the peripheral contours of the support layer 2 and the massage layer 3 match the side wall contours of the assembly groove 4 to reduce the gaps between the support layer 2 and the assembly groove 4 and between the massage layer 3 and the assembly groove 4. The contour of the support layer 2 matches the bottom contour of the cavity of the assembly groove 4, the contour of the massage layer 3 matches the top contour of the cavity of the assembly groove 4, and the sum of the heights of the support layer 2 and the massage layer 3 is the same as the depth of the cavity of the assembly groove 4. During installation, the support layer 2 and the massage layer 3 are sequentially stacked and installed in the assembly groove 4. After installation in place, the support layer 2 overlaps on the bottom wall of the assembly groove 4, the side wall of the support layer 2 matches and fits with the bottom of the side wall of the cavity of the assembly groove 4, the massage layer 3 overlaps on the top surface of the support layer 2, the side wall of the massage layer 3 matches and fits with the top of the side wall of the cavity of the assembly groove 4, and the top surface of the massage layer 3 is flush and joined with the peripheral edge of the opening of the assembly groove 4 to form a continuous and flat supporting surface.

[0032] In this embodiment, both the support layer 2 and the massage layer 3 are in the shape of a regular cuboid, and the cavity of the assembly groove 4 is also in the shape of a cuboid, which not only ensures that the assembly groove 4 can play a role in horizontally limiting the support layer 2 and the massage layer 3, but also facilitates processing, disassembly, and maintenance. Moreover, it can effectively reduce the wall thickness of the side wall of the base 1, thereby ensuring good support in a relatively large area in the middle of the top surface of the cushion body.

[0033] In this embodiment, the base 1 includes a first outer casing 25, the support layer 2 includes a second outer casing 26, and the massage layer 3 includes a third outer casing 27. The first outer casing 25, the second outer casing 26, and the third outer casing 27 can not only tightly wrap the central block of the base 1, the support layer 2, and the corresponding components inside the massage layer 3, playing a role in protection and shaping, but also effectively reduce the assembly resistance, facilitate the disassembly, assembly, and maintenance of the base 1, the support layer 2, and the massage layer 3. Moreover, it is convenient for disassembly and cleaning, thereby reducing the cleaning requirements of the wrapped components and facilitating maintenance.

[0034] In this embodiment, the base 1 includes a bottom plate 5 and a sponge perimeter. The sponge perimeter is arranged along the peripheral edge of the top surface of the bottom plate 5 and encloses to form the assembly groove 4. The sponge perimeter is in a square frame shape and includes side perimeters 6 and end perimeters 7 (as Figure 2 shown). The side perimeters 6 and the end perimeters 7 are alternately arranged on each edge of the top surface of the bottom plate 5, and then enclose to form the assembly groove 4 through adhesive bonding, ensuring that the base 1 has good structural strength and playing a role in clamping and limiting the massage layer 3 and the support layer 2.

[0035] In this embodiment, the inner cavity contour of the first outer casing 25 matches the contour of the base 1, so that the bottom plate 5 and the sponge perimeter are tightly wrapped by the first outer casing 25, effectively restricting the offset between the bottom plate 5 and the sponge perimeter.

[0036] In this embodiment, a deformation groove 8 is opened at the top edge of the side perimeter 6, and a deformation hole 9 is opened in the middle. Both the deformation groove 8 and the deformation hole 9 are opened through, which is not only convenient for processing, but also realizes the adjustment of the softness and hardness of each area of the side perimeter 6 by adjusting the sizes of the deformation groove 8 and the deformation hole 9, effectively improving the support comfort.

[0037] In this embodiment, the support layer 2 is in the shape of a cuboid and includes a front block 10, a middle block, and a rear block 11 (as Figure 3 shown) that are sequentially arranged from front to back. The support layer 2 is lapped on the bottom wall of the assembly groove 4 through a flat bottom surface and supports the massage layer 3 through a flat top surface. By setting the front block 10, the middle block, and the rear block 11, the support layer 2 is divided into multiple partitions to provide differential support for each body segment of the user. The front block 10, the middle block, and the rear block 11 are all rectangular and arranged neatly, ensuring that the relative positions among the three are fixed and forming a flat top surface for supporting the massage layer 3.

[0038] In this embodiment, the middle block includes a support bladder group 12 and two support pads 13. The support pads 13 are provided with through holes 14. The support bladder group 12 includes support air bladders arranged in a matrix and an air path platform 15 disposed in the middle of the support air bladders. The support pads 13 vertically clamp the air path platform 15 and are sleeved on the ends of the support air bladders through the through holes 14. The support pads 13 are vertically stacked and tightly clamp the air path platform 15, playing a role in clamping and limiting the support air bladders. The top and bottom of the support air bladders are respectively inserted into the through holes 14 of the corresponding support pads 13. The through holes 14 play a role in telescopic guiding for the support air bladders, ensuring that the support air bladders can perform vertical telescoping and adjusting the softness and hardness of the middle block. The middle block is tightly wrapped by the second outer cover 26, ensuring the relative positions of the support pads 13 and the support bladder group 12 are fixed, ensuring that the support bladder group 12 is tightly clamped by the support pads 13, and facilitating the disassembly and cleaning of the second outer cover 26.

[0039] In this embodiment, the front block 10 is a cuboid sponge pad, and the rear block 11 is a cuboid spring pad. By setting different support structures, differential support properties are obtained, thereby meeting the differential support requirements of various body segments of the user. In addition, the front block 10, the middle block, and the rear block 11 can adjust the type of support structure and the size according to needs, and all should be regarded as specific embodiments of the present invention.

[0040] In this embodiment, the massage layer 3 is in the shape of a cuboid and includes a fixed pad 17 and a massage bladder group 16 (as Figure 5 shown). The massage bladder group 16 includes massage air bladders arranged in a matrix. The massage air bladders form a massage stimulus applied upward through inflation and deflation. The massage bladder group 16 realizes vertical reciprocating telescoping through inflation and deflation, thereby generating a massage stimulus transmitted upward to provide massage services for the user. The massage air bladders are arranged in a matrix to ensure that all areas on the user's surface can be effectively pressed, improving massage comfort.

[0041] In this embodiment, the massage layer 3 includes a limit pad 18, an upper pad 20, and a lower pad 21 (as Figure 4 shown). The limit pad 18 is provided with through holes 19 for the massage air bladders to pass through. During installation, the upper pad 20, the limit pad 18, the massage bladder group 16, the fixed pad 17, and the lower pad 21 are stacked in sequence from top to bottom and are tightly wrapped by the third outer cover 27. The massage air bladders on the massage bladder group 16 are inserted into the through holes 19. The through holes 19 play a role in telescopic guiding for the massage air bladders and can also play a role in hiding the deflated and contracted massage air bladders, ensuring that the top surface of the massage layer 3 remains flat and effectively reducing the sense of foreign body.

[0042] Embodiment Two:

[0043] Compared with the first embodiment, this embodiment provides another type of mattress.

[0044] As Figure 6 and 7 shown in the mattress, the support layer 2 is inserted and installed at the bottom of the assembly groove 4, and the massage layer 3 inserted into the assembly groove 4 covers the support layer 2 and is fixedly connected to the base 1 through a zipper 22, so that the support layer 2 is clamped between the massage layer 3 and the bottom surface of the assembly groove 4. The support layer 2 is installed at the bottom of the assembly groove 4, the massage layer 3 is inserted into the assembly groove 4 and connected to the base 1 through a zipper 22, and the support layer 2 is clamped and fixed between the bottom wall of the assembly groove 4 and the massage layer 3. It not only clamps and positions the support layer 2 by fixedly connecting the massage layer 3, simplifies the steps for convenient assembly, but also does not require the use of glue, meets the environmental protection requirements, does not affect the health of users, and is also convenient for disassembly and maintenance, improving the use experience.

[0045] In this embodiment, the zipper 22 includes a second chain 24 provided on the side edge of the top surface of the massage layer 3 and a first chain 23 provided on the side edge of the notch of the assembly groove 4. The massage layer 3 is inserted into the assembly groove 4 and fixedly connected by meshing the first chain 23 with the second chain 24, so that the top surface of the massage layer 3 is flush with the top surface of the base 1 and forms a flat supporting surface. During installation, first, the support layer 2 is inserted at the bottom of the assembly groove 4, then, the massage layer 3 is inserted into the assembly groove 4 and overlaps above the support layer 2, and finally, the massage layer 3 is fixedly connected by meshing the second chain 24 with the first chain 23 provided on the base 1.

[0046] After being installed in place, the massage layer 3 and the base 1 are fixedly connected by the zipper 22 to prevent the massage layer 3 from disengaging from the assembly groove 4, and the support layer 2 is clamped between the bottom surface of the massage layer 3 and the bottom wall of the assembly groove 4 to prevent the support layer 2 from disengaging. It can not only firmly connect the support layer 2 and the base 1, and the massage layer 3 and the base 1 at the same time through the operation of fixedly connecting the massage layer 3 and the base 1, improve the assembly efficiency by simplifying the steps, but also facilitate meshing and fixing by setting the zipper 22, which is convenient for disassembly and maintenance. It can also ensure that the top surface of the massage layer 3 and the top surface of the base 1 are joined to form a flat and continuous supporting surface, provide a comfortable support for users, eliminate the sense of foreign objects by reducing the gap between the massage layer 3 and the base 1, and thus improve the use experience.

[0047] In this embodiment, the first chain 23 is attached to the side edge of the notch of the assembly groove 4, and the second chain 24 is attached to the side edge of the top surface of the massage layer 3. Specifically, the first chain 23 is sewn on the first outer cover 25 at the long side edge of the notch of the assembly groove 4, and the second chain 24 is sewn on the long side edge of the third outer cover 27 at the top surface of the massage layer 3. The meshing edges of the second chain 24 and the first chain 23 are arranged facing each other and approaching each other, and the distance between the side wall of the assembly groove 4 and the side wall of the massage layer 3 is reduced by the meshing of the zipper 22. The second chain 24 is arranged to be of the same length as the long side edge of the massage layer 3, and the first chain 23 is arranged to be of the same length as the long side edge of the notch of the assembly groove 4. The lengths of the first chain 23 and the second chain 24 are the same, ensuring that the two can be matched and meshed, preventing the situation that the ends are not effectively used after meshing due to the non-corresponding lengths of the first chain 23 and the second chain 24, and preventing the generation of a foreign body sensation. The first chain 23 is provided on both long side edges of the assembly groove 4, and the second chain 24 is provided on both long side edges of the top surface of the massage layer 3. The massage layer 3 is inserted into the assembly groove 4 and the corresponding first chain 23 and second chain 24 are meshed and fixed, which not only facilitates disassembly and assembly by reducing the number of zippers 22, but also increases the laying length of the zipper 22 by arranging it on the long side edge, thereby improving the fixing reliability.

[0048] In this embodiment, the cavity of the assembly groove 4 is in the shape of a cuboid, and the vertical projection contours of the support layer 2 and the massage layer 3 coincide with the contour of the bottom wall of the assembly groove 4, so as to eliminate the gaps between the support layer 2, the massage layer 3 and the assembly groove 4. Specifically, the vertical projections of the support layer 2, the massage layer 3 and the assembly groove 4 coincide, so that the support layer 2 and the massage layer 3 can be fitted with the side walls of the assembly groove 4 through the side walls, and the horizontal distance between the first chain 23 and the second chain 24 is shortened by reducing the distance between the side wall of the massage layer 3 and the side wall of the assembly groove 4. The sum of the support layer 2 and the massage layer 3 is the same as the depth of the cavity of the assembly groove 4, so that the top surface of the massage layer 3 and the peripheral edge of the notch of the assembly groove 4 are at the same height, and the vertical distance between the first chain 23 and the second chain 24 is shortened by reducing the distance between the top surface of the massage layer 3 and the notch of the assembly groove 4. Thus, it is ensured that the first chain 23 and the second chain 24 can be accurately meshed after the massage layer 3 is assembled in place, and further ensured that the massage layer 3 is accurately positioned and forms a flat, neat and continuous supporting surface with the top surface of the base 1.
