Description

Technical Field

[0001] The utility model relates to the technical field of outdoor inflatable mattresses, in particular to a mattress body and an inflatable mattress. Background Art

[0002] In the existing bedding market, mattresses are indispensable resting products in people's daily lives, and their comfort and support have always been the focus of consumers. Traditional mattress designs often use uniform materials and structures, which are difficult to fully adapt to different body shapes, sleeping positions, and different pressure distributions generated by various parts of the human body during sleep. This limitation causes many users to feel uncomfortable when sleeping, especially for those who have high requirements for sleep quality. In order to solve the shortcomings of traditional mattresses, a variety of mattress products with innovative designs have gradually appeared on the market, among which the method of adjusting the internal structure of the mattress to achieve differentiated support has received widespread attention. However, most of these products have problems such as complex structure, high cost, or unsatisfactory support effect, which are difficult to meet the needs of consumers.

[0003] Existing patent number CN103945737A discloses a mattress and a bed device using the mattress, which can efficiently apply shear stress to the through holes of the mattress to make it easy to shrink, and the through holes are not formed into a waveform and the number and area of ​​the holes are unchanged compared with the past. For this purpose, a plurality of holes with straight-shaped portions having an angle inclined relative to the width direction of the mattress are formed at the foot of the mattress at every specified interval toward the thickness direction of the above-mentioned foot. The above-mentioned multiple holes are arranged in a zigzag shape on the mattress when viewed from above. However, since different parts of the human body exert different pressures on the mattress when lying on the mattress, the mattress only has straight-shaped holes to provide support and cannot better fit the pressure of the human body. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a cushion body and an inflatable cushion, and the utility model adopts the following technical solutions:

[0005] A cushion body is used in a manner that the ends in the longitudinal direction are subjected to compression by the human body. The cushion body is provided with a plurality of through holes in the direction in which deformation occurs due to compression, and the through holes form a first force-bearing area and a second force-bearing area on the cushion body. The through holes in the first force-bearing area and the second force-bearing area have different sizes and / or shapes so as to adapt to and support the weight of the human body according to the pressure distribution of the human body lying on the cushion body.

[0006] Furthermore, the first stress-bearing areas are arranged in the head, back and buttocks regions of the cushion body, and a first longitudinal through hole having a smaller size is formed therein to increase the support and stability of the mattress.

[0007] Furthermore, the first longitudinal through hole is a circular hole with a hole diameter of 1.0-2.5 cm.

[0008] Furthermore, the rest of the cushion body is provided with a second stress-bearing area, which is formed by an arrangement of larger second longitudinal through holes, and the second longitudinal through holes are regularly arranged on the cushion body when viewed from above to adapt to the smaller pressure distribution in these parts.

[0009] Furthermore, the second longitudinal through holes are formed by penetrating a plurality of holes including a straight-line portion inclined with respect to the width direction of the mattress at predetermined intervals in the portion deformed by the compression.

[0010] Furthermore, the plurality of holes are arranged on the mattress in a zigzag shape when viewed from the side.

[0011] Furthermore, the second longitudinal through holes are arranged on the mattress body in a centrally symmetrical manner in a manner of being inclined at 25°-75° relative to the length direction of the mattress.

[0012] Furthermore, the pad body is a sponge pad with a thickness of 30mm-45mm.

[0013] An inflatable mattress includes a mattress body and a cushion body fixedly arranged therein. The inflatable structure of the mattress body is designed to cooperate with the through holes of the cushion body, so that the mattress can provide differentiated support forces according to the density of the through holes in different areas when inflated.

[0014] Furthermore, the cushion body is adhered to the inside of the mattress body on all sides.

[0015] The beneficial effects of the utility model are:

[0016] (1) The utility model provides a new type of cushion body and an inflatable cushion used therein, which achieves precise adaptation and support to the pressure distribution of various parts of the human body by optimizing the layout of the through holes inside the cushion body.

[0024] like Figure 1-Figure 3As shown, the utility model discloses a cushion body, which is used in a way of being placed in an outdoor inflatable cushion. The outdoor inflatable cushion is used in various scenes such as camping, home, office, medical care, and travel exploration; in this embodiment, the mattress is a sponge pad 1. The thickness of the sponge pad is 38mm. This thickness range not only ensures sufficient support, but also takes into account the lightness and portability of the mattress. Its entirety (the part where the user's body is placed, such as the middle part or the middle upper part of the full length of the mattress) becomes the part that is deformed by compression caused by pressing at the end of the longitudinal direction. The sponge pad 1 is a single-layer or multi-layer plate made of polyurethane foam material. The sponge pad 1 has a plurality of through holes in the direction of deformation due to compression, and the through holes form a first force-bearing area 11 and a second force-bearing area 12 on the cushion body; the size and / or shape of the through holes in the first force-bearing area 11 and the second force-bearing area 12 are different, so as to adapt to and support the weight of the human body according to the pressure distribution of the human body lying on the cushion body. Specifically, the first stress-bearing area 11 is arranged in the head, back and buttocks areas of the cushion body, and a first longitudinal through hole 111 with a smaller size is formed inside the first stress-bearing area 11 to increase the support and stability of the mattress. In the present embodiment, the first longitudinal through hole 111 is a circular hole with a hole diameter of 1.5 cm. In other embodiments, the first through hole 111 is an elliptical or square through hole with a smaller hole diameter and is distributed in the first stress-bearing area 11 in a dense manner to achieve support for body parts with greater pressure such as the head, back and buttocks. The rest of the cushion body is provided with a second stress-bearing area 12, which is composed of larger second longitudinal through holes 121 arranged in a regular manner on the cushion body when viewed from above to adapt to the smaller pressure distribution in these parts. On the sponge pad 1, except for the head, back and buttocks areas, a plurality of second longitudinal through holes 121 with a straight-line portion with an angle inclined relative to the width direction of the mattress are formed at specified intervals in the thickness direction. As shown Figure 3 As shown, the second longitudinal through hole 121 is arranged in a zigzag shape on the mattress when viewed from above in the cross-sectional view. It can be formed so that its straight-shaped portion is inclined at 45° relative to the width direction of the mattress 10. In this embodiment, the plurality of second longitudinal through holes 121 are arranged so that the angle formed by the straight-shaped portion relative to the width direction of the mattress is 45°. Specifically, the second longitudinal through holes 121 are arranged on the sponge pad 1 in a manner of being inclined at 45° relative to the length direction of the mattress through a plurality of central symmetric arrangements.

[0025] It should be noted that, in the present embodiment, the through holes in the first stress-bearing zone 11 are all circular holes with the same aperture size. Since the pressure exerted on the sponge pad 1 by the head, back and buttocks of the human body is also different, the first stress-bearing zone can also be divided into the head stress-bearing zone, the back stress-bearing zone and the buttocks stress-bearing zone. The three can use circular holes, elliptical holes or square holes with different apertures and densities to adapt to the pressure in different areas.

[0026] In this embodiment, a plurality of second longitudinal through holes 121 are formed in a straight line portion and are inclined relative to the width direction of the mattress. A plurality of second longitudinal through holes 121 are formed to be arranged at the same inclination angle in the width direction, and are formed in a sawtooth shape in the longitudinal direction, where every other row is arranged in an inclined direction in the opposite direction. In this way, since a plurality of second longitudinal through holes 121 are formed to be inclined relative to the width direction of the mattress, even holes with corner portions will exert force in the direction of the relative sides being staggered, and the shear stress also acts on the entire periphery of the second longitudinal through holes 121. Since the corner portions have a degree of freedom for the shear stress, the second longitudinal through holes 121 are easy to deform. In addition, by configuring the second longitudinal through holes 121 in a sawtooth shape, the shear stress can be uniformly transmitted to the entire sponge pad 1. Since the compression deformation of the second longitudinal through holes 121 is easily generated along the inclination of the straight line, the compression deformation of the sponge pad 1 to one side in the width direction can be prevented by alternating in this way. At the same time, the weight of the entire sponge pad 1 can be reduced, making it easier to pick up.

[0027] The utility model also provides an inflatable mattress, comprising a mattress body, and a sponge pad 1 fixedly arranged inside the mattress body, wherein the sponge pad 1 is adhered to the inside of the mattress body on all sides. The inflatable structure of the mattress body is designed to cooperate with the through holes of the mattress body, so that the mattress can provide differentiated support forces according to the density of the through holes in different areas when inflated.

[0028] The above are only preferred embodiments of the present invention. The protection scope of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be regarded as the protection scope of the present invention.
