Description

Technical Field

[0001] The utility model relates to a mattress in the field of bedding, in particular to a mattress capable of maintaining a flat surface. Background Art

[0002] Common spring mattresses use different materials to splice a cushion layer with different zoning effects on a plane and cover it on the spring core layer as a comfort layer. Since there is a lack of effective fixation for the splicing materials on both the upper and lower surfaces of the comfort layer, these materials spliced on the plane will shift and squeeze during use. Over time, the middle materials will bulge and protrude, and then the middle of the mattress will also arch accordingly, resulting in an uneven surface of the mattress, seriously affecting the supporting sleeping feeling and comfort of the mattress. Content of the Utility Model

[0003] To solve the technical problem that the comfort layer of the existing mattress is spliced with materials but lacks effective fixation, and the materials shift and squeeze during use, resulting in the middle materials bulging out, causing the surface of the mattress to be uneven and affecting the supporting sleeping feeling and comfort of the mattress, the utility model provides a mattress capable of maintaining a flat surface. By making reliable positioning of the splicing materials of the comfort layer, it prevents the materials from shifting and squeezing and the resulting bulging, so that the surface of the mattress can also be maintained flat during long-term use, ensuring the supporting sleeping feeling and comfort of the mattress.

[0004] The technical solution adopted by the utility model to solve the technical problem: A mattress capable of maintaining a flat surface includes a top layer, a comfort layer, a spring core layer and a bottom layer arranged from top to bottom, and a fence arranged around the spring core layer. The comfort layer is spliced and composed of elastic zones and breathable zones alternately distributed along the length direction of the mattress. The elastic zones and breathable zones are made of different materials. The characteristic is that a base layer is provided between the comfort layer and the spring core layer. The materials of the elastic zones and breathable zones are both fixed on the base layer, and the comfort layer and the base layer are fixedly connected into an integral sub-component unit. The utility model fixes the materials of each zone on the comfort layer on the same base layer, so that various materials spliced to form the comfort layer can have fixed positions on the base layer, and the different materials will not shift and squeeze, effectively avoiding the bulging of the materials caused by the shift and squeeze and the resulting arching and unevenness of the mattress surface, ensuring that the surface of the mattress can also be maintained flat during long-term use without unevenness and bulges. The sub-component unit formed by fixedly connecting the comfort layer and the base layer can be used as an independent component for batch manufacturing and production, improving production efficiency. The bottom layer is usually made of latex.

[0005] As a further improvement and supplement to the above technical solution, the present utility model adopts the following technical measures: The materials of the elastic zone and the breathable zone are adhesively fixed on the base layer by glue and spliced to form a comfort layer. The materials of each partition of the comfort layer are adhesively bonded to the surface of the base layer for connection and fixation, and after the positions are fixed, they are spliced into a comfort layer. Different materials are adhesively fixed and spliced on the base layer to form a comfort layer. By adjusting and pasting different types of materials on the base layer, it is very convenient to change the number of partitions of the comfort layer and adjust the functions of each partition.

[0006] Preferably, the glue covers the contact surface between the base layer and the comfort layer. Compared with the conventional strip-shaped glue application scattered in multiple places, the glue covers the entire surface of the base layer in contact with the comfort layer, which can better ensure the largest bonding area between the base layer and the comfort layer and improve the reliability of the fixed connection.

[0007] Preferably, the glue covers the contact surface between the base layer and the comfort layer by rolling and gluing along the length direction of the mattress. Rolling and gluing means rolling and coating the glue on the surface of the base layer along the length direction of the mattress under pressure, so that the glue is evenly applied on the surface of the base layer and fully penetrates with the help of pressure, to ensure that the materials of each partition of the comfort layer can be firmly adhered to the base layer, thereby avoiding unevenness caused by bulging due to material displacement and extrusion.

[0008] Preferably, the base layer is made of sponge material and has a thickness of 1.5 - 2.5 cm. The base layer is also made of commonly used sponge material, which is convenient for processing, has a low cost, and the glue is easy to penetrate into the base layer, so that the base layer and the upper comfort layer are firmly adhered and fixed.

[0009] Preferably, the elastic partition is made of sponge material or latex material, and the breathable partition is made of 3D material. The elastic partition is made of sponge or latex, which has sufficient elasticity to meet the support requirements of the corresponding partition; the breathable partition is made of 3D material, which has good breathability and certain elastic support performance to meet the working needs of the corresponding partition.

[0010] Preferably, the spring core layer is wrapped in the accommodation cavity formed by the enclosure, and the top surface of the enclosure is higher than the top surface of the spring core layer. The sub-unit is covered on the spring core layer, and the periphery of the comfort layer in the sub-unit is at the same height as the top surface of the adjacent enclosure. The upper layer is a felt cloth pressed and covered on the enclosure and the comfort layer. The spring core layer is wrapped in the accommodation cavity formed by the enclosure, and at the same time, the top surface height is also lower than the top surface of the outer enclosure. The comfort layer is at the same height as the enclosure. Thus, both the spring core layer and the comfort layer are wrapped and fixed by the enclosure and will not shift or deviate. The felt cloth, as the upper layer, covers the enclosure and the comfort layer through a pressing process.

[0011] Preferably, the thickness of the felt cloth is 0.3 - 0.5 cm. The thickness of the felt cloth is appropriate within this range. If the felt cloth is too thick, it will affect the comfort of the mattress; if it is too thin, it is easy to wear out after a long time.

[0012] Preferably, both the spring core layer and the comfort layer are provided with three zones distributed along the length direction of the mattress. The hardness of the two end zones in the three zones of the spring core layer is less than that of the middle zone. The three zones of the comfort layer include a ventilation zone and elastic zones sandwiching both sides. On the premise of meeting the support of different parts of the body by the mattress, both the spring core layer and the comfort layer adopt a three-zone design, which can simplify the process, reduce costs, and the zones of the upper and lower layers are superimposed and corresponding, making the sleeping feeling of the mattress more comfortable.

[0013] Preferably, the hardness of the two end zones in the three zones of the spring core layer is the same. Most of the existing spring core layers adopt independent pocket springs. Limiting the same hardness of the two end zones can effectively simplify the types of independent pocket springs, thereby simplifying the process and reducing costs.

[0014] The beneficial technical effects of the present utility model: Fix the materials of each zone on the comfort layer to the same base layer, and the materials of each zone can have a fixed position on the base layer, preventing displacement and extrusion between the materials, avoiding the bulging of the materials caused by the displacement and extrusion of the materials of each zone due to the inability to be fixed during the long-term use of the mattress, and the uneven arching of the mattress surface caused thereby, ensuring that the surface of the mattress can remain flat even during long-term use; The sub-unit formed by the fixed connection of the comfort layer and the base layer can also be used as an independent component that can be mass-produced, further improving the production efficiency of the mattress.

[0019] The present utility model will be further described below in conjunction with the description of the drawings and the detailed embodiments.

[0020] As Figures 1 to 3As shown in the figure, the utility model relates to a mattress capable of keeping the surface flat, which comprises a top layer 1, a comfort layer 2, a spring core layer 3 and a bottom layer 6 arranged from top to bottom, and a fence 5 arranged around the spring core layer 3. The comfort layer 2 is composed of elastic zones 2-1 and breathable zones 2-2 which are alternately distributed along the length direction of the mattress. The elastic zones and the breathable zones are made of different materials. A base layer 4 is arranged between the comfort layer 2 and the spring core layer 3. The materials of the elastic zones and the breathable zones are both fixed on the base layer 4. In this embodiment, the materials of the elastic zones 2-1 and the breathable zones 2-2 are both pasted and fixed on the base layer 4 with glue and are spliced to form the comfort layer 2. The comfort layer 2 and the base layer 4 are fixedly connected into an integral sub-unit.

[0021] Since the materials of each partition on the comfort layer are fixedly connected to the base layer, the materials of each partition have their respective fixed positions on the base layer, and the materials of different types will not shift and squeeze each other. Therefore, it effectively avoids the material bulging caused by the original shift and squeeze, and the mattress surface arching and bulging caused by the material bulging, ensuring that the mattress surface remains flat during long-term use and improving the comfort of the mattress. In addition, the sub-unit formed by fixedly connecting the comfort layer and the base layer can be used as an independent component for mass production, improving efficiency. In this embodiment, the bottom layer is usually made of latex material, which has good elasticity and breathability.

[0022] Furthermore, the glue used for fixedly connecting the comfort layer 2 and the base layer 4 covers the contact surface between the base layer 4 and the comfort layer 2 by rolling and gluing. Compared with the existing method of scattered strip gluing at multiple places, the glue covers the entire surface of the base layer in contact with the comfort layer, which can further ensure the maximum bonding area between the base layer and the comfort layer and improve the reliability of the fixed connection. The rolling and gluing is to roll and apply glue on the surface of the base layer along the length direction of the mattress while applying pressure. The glue is evenly applied on the surface of the base layer and fully penetrates into the bonding surface of the base layer with the help of the applied pressure, so that the materials of each partition of the comfort layer are firmly bonded and fixed on the base layer, preventing displacement and extrusion caused by lack of fixation of the materials and thus avoiding the unevenness of the mattress surface caused by bulging. In this embodiment, hot melt adhesive (commonly known as PUR) is used for gluing by means of a roller process.

[0023] Furthermore, the base layer 4 is made of sponge material and has a thickness of 1.5-2.5 cm, preferably 2 cm. The elastic zone 2-1 is made of sponge material or latex material, preferably sponge. The breathable zone 2-2 is made of 3D material.

[0024] The base layer is also made of common sponge, which is convenient to process and has low cost, and the glue is easy to penetrate into it, so that the base layer and the upper comfort layer are firmly bonded and fixed. The elastic partition can be made of sponge or latex, which has enough elasticity to meet the support requirements of the partition. The breathable partition made of 3D material also has good breathability and certain elastic support, meeting the working requirements of the corresponding partition.

[0025] Furthermore, the spring core layer 3 is wrapped in the accommodation cavity formed by the enclosure 5, and the top surface of the enclosure 5 is 2 higher than the top surface of the spring core layer 3. The sub-component unit formed by fixedly connecting the comfort layer 2 and the base layer 4 is covered on the spring core layer 3. The periphery of the comfort layer 2 in the sub-component unit is at the same height as the top surface of the adjacent enclosure 5. The upper layer 1 is a felt cloth press-fitted and covered on the enclosure 5 and the comfort layer 2. The thickness of the felt cloth is 0.3 - 0.5 cm, preferably 0.4 cm.

[0026] The spring core layer is wrapped in the accommodation cavity formed by the enclosure. The top surface of the enclosure is higher than the spring core layer. After the comfort layer is covered on the spring core layer, it is flush with the height of the enclosure. Then, it is tightly press-fitted with a felt cloth. The comfort layer and the spring core layer are both wrapped by the enclosure for positioning and will not shift or deviate.

[0027] As shown in the figure, in this embodiment, both the spring core layer 3 and the comfort layer 2 are divided into three zones along the length direction of the mattress. Among the three zones of the spring core layer 3, the hardness of the two end zones is less than that of the middle zone. In this embodiment, the hardness of the two end zones is the same; the three zones of the comfort layer 2 include the middle ventilation zone 2-2 and two identical elastic zones 2-1 sandwiching it on both sides.

[0028] On the premise of meeting the support requirements of the mattress, both the spring core layer and the comfort layer adopt a simplified three-zone design, which has simple technology and low cost. At the same time, the zones of the upper and lower layers are superimposed and corresponding, making the sleeping feeling of the mattress more comfortable.
