DETAILED DESCRIPTION OF EMBODIMENTS

The present invention will be further described below with reference to the accompanying drawings.
In the present application, it should be noted that a direction along X-axis in FIG. 1 is defined as a lateral direction, a direction along Y-axis is defined as a longitudinal direction, and a direction along Z-axis is defined as a vertical direction, for the sake of convenience.
FIG. 1 shows a structure of an ergonomic sleeping mat 100 according to the present invention. As shown in FIG. 1 , the ergonomic sleeping mat 100 comprises a sleeping mat body 1. The sleeping mat body 1 includes a sleeping mat layer 2 and a ground mat layer 3, which are symmetrically arranged with respect to a vertical central plane. The sleeping mat layer 2 and the ground mat layer 3 are connected to each other to form into one piece, thereby forming a closed accommodation cavity 4 (see FIG. 5 ) between the sleeping mat layer 2 and the ground mat layer 3. In one embodiment, the sleeping mat layer 2 and the ground mat layer 3 are configured as a unitary structure. The sleeping mat layer 2 and the around mat layer 3 may also be bonded into one piece through high-frequency welding.
According to the present invention, the ergonomic sleeping mat 100 further comprises a plurality of tensioning bands 5 arranged within the closed accommodation cavity 4. As shown in FIG. 1 and FIG. 2 , a plurality of tensioning bands 5 is arranged within the closed accommodation cavity 4 at intervals along the longitudinal direction. An upper end of the tensioning band 5 is fixedly bonded to the sleeping mat layer 2, and a lower end thereof is fixedly bonded to the ground mat layer 3. In this manner, adjacent tensioning bands 5, the sleeping mat layer 2 and the ground mat layer 3 together form a plurality of inflatable cavities 51 distributed sequentially along the longitudinal direction within the closed accommodation cavity 4. When filled with air, the inflatable cavities 51 can expand the sleeping mat body 1, so as to provide a rigid support for the sleeping mat layer 2, thereby forming a sleeping mat for rest and sleep. The tensioning band 5 is made of cloth, and preferably, for example, of oxford cloth material.
In one embodiment, the sleeping mat layer 2 and the ground mat layer 3 of the sleeping mat body 1 can be made from nylon material or polyester fiber, for example. Preferably, the sleeping mat layer 2 and the ground mat layer 3 are made from a fabric formed by compounding thermoplastic polyurethane elastic film on the nylon/polyester fiber material, in order to facilitate the welding. In this manner, the sleeping mat body 1 can expand under air pressure to provide support and become elastic, which can enhance the softness of the sleeping mat layer 2, and thus make the ergonomic sleeping mat 100 more comfortable. In addition, since the sleeping mat body 1 is made from the above materials, the light weight and portability of the sleeping mat body 1 can be ensured. At the same time, the ergonomic sleeping mat 100 is able to bear the weight of the human body while maintaining its portability.
According to the present invention, in the inflated state, a longitudinal length of the sleeping mat body 1 is configured to be within a range of about 130-200 centimeters, a lateral width thereof is configured to be within a range of about 50-75 centimeters, and a vertical thickness thereof is configured to be within a range of about 5-10 centimeters. The above sizes of the sleeping mat body 1 can be adapted for users of different heights, enhancing the applicability of the ergonomic sleeping mat 100.
According to the present invention, a plurality of inflatable cavities 51 is in communication with each other. In one embodiment, an inflation channel (not shown) is provided within the closed accommodation cavity 4, so that the plurality of inflatable cavities 51 is in communication with each other through the inflation channel. Preferably, the inflation channel is arranged out of the tensioning bands 5 along the lateral direction, and extends along the longitudinal direction, thereby connecting a plurality of inflatable cavities 51. The sleeping mat body 1 is provided with an inflation port (not shown) in communication with the inflation channel, for inflating the inflatable cavities 51. Therefore, all the inflatable cavities 51 can be inflated through the inflation port during use. Also, the air in the inflatable cavities 51 can be discharged through the inflation port, so that the ergonomic sleeping mat 100 can be folded and thus is easy to carry. This not only facilitates the inflation and improves the inflation efficiency, but also facilitates portability.
In a preferred embodiment, the inflation port is arranged on a side wall region of the sleeping mat body 1, at a lateral side position with respect to the inflation channel.
According to one embodiment of the present invention, the upper end of the tensioning band 5 is fixedly bonded to a lower surface of the sleeping mat layer 2 through face-to-face connection, and the lower end thereof is fixedly bonded to an upper surface of the ground mat layer 3 through face-to-face connection. Preferably, the tensioning band 5 can be fixedly bonded to the sleeping mat layer 2 and the ground mat layer 3, for example, through hot pressing or high-frequency welding. In the inflated state, all the inflatable cavities 51 are filled with air, so that each tensioning band 5 presents a C-shaped configuration under the influence of air.
According to one embodiment of the present invention, as shown in FIG. 3 , the sleeping mat layer 2 of the ergonomic sleeping mat 200 comprises an upper body portion 201, a waist portion 202 and a lower limb portion 205 corresponding to different parts of the human body, respectively. The lower limb portion 205 may comprise a hip portion 203 and a leg portion 204 to fit different parts of the human body.
As shown FIG. 4 , the waist portion 202 is configured to be higher than the upper body portion 201 and the lower limb portion 205, i.e., forms a projection relative to the upper body portion and the lower limb portion, thereby contacting with the waist of the human body to support the waist. According to one embodiment of the present invention, the waist portion 202 is about 0.5-2 cm, and preferably about 0.75-1.5 cm, thicker than the upper body portion 201, the hip portion 203, and the leg portion 204. More preferably, the waist portion 202 is 1 cm thicker than the upper body portion 201, the hip portion 203, and the leg portion 204. The above structure of the sleeping mat layer 2 can significantly improve the comfort of the ergonomic sleeping mat 200. According to one embodiment of the present invention, the thickness of the waist portion 202 is about 7-11 cm, and preferably 8-10 cm. It should be noted that the thickness of the waist portion 202 refers to that of a side of the ergonomic sleeping mat 200 in contact with the human body when in use.
In order to ensure little deformation of each region of the sleeping mat layer 2 when the human body is on the ergonomic sleeping mat 200, the air pressure within the inflatable cavities 51 of the ergonomic sleeping mat 200 is about 2-5 kPa after inflation, which can effectively ensure that the ergonomic sleeping mat 200 can provide a certain rigid support after inflation.
According to another embodiment of the present invention as shown in FIG. 5 and FIG. 6 , the sleeping mat layer 2 of the ergonomic sleeping mat 100 includes a neck region 21, a back region 22, a waist region 23, a leg region 24, and an ankle region 25 that correspond to and adapt to different parts of the human body, respectively. Among them, the neck region 21 and the back region 22 are configured to form the upper body portion 201, the leg region 24 and the ankle region 25 are configured to form the lower limb portion 205, and the waist region 23 is configured to correspond to the waist and the hip of the human body. The tensioning bands 5 corresponding to the neck region 21, the hack region 22, the waist region 23, the leg region 24, and the ankle region 25 respectively are configured to have different heights and sizes. In this manner, when the inflatable cavities 51 are in the inflated state, the neck region 21, the back region 22, the waist region 23, the leg region 24, and the ankle region 25 of the sleeping mat layer 2 will form human body contact surfaces of different heights adapted to the contour of the human body, and provide rigid support. As a result, the neck region 21, the back region 22, the waist region 23, the leg region 24, and the ankle region 25 can provide respective undulating surfaces with different heights, thereby forming an ergonomic structure. This structure of the sleeping mat layer 2 is particularly effective in relieving the pressure on the neck, the waist, the leg, the ankle and other parts of the human body, so as to produce a soothing effect, improve the sleep quality, and make the human body more comfortable.
According to the present invention, the neck region 21 is configured to have a constant height along the lateral direction. Moreover, the tensioning hands 5 corresponding to the neck region 21 are fixedly bonded with the sleeping mat layer 2 and the ground mat layer 3 along the lateral direction in a continuous manner, thereby forming a plurality of protruding strips 211 extending continuously along the lateral direction in the neck region 21 of the sleeping mat layer 2 (see FIG. 6 ).
In one embodiment, the plurality of tensioning bands 5 corresponding to the neck region 21 is configured to have the same vertical height, which remains unchanged along the lateral direction. In the inflated state, the portion of the sleeping mat layer 2 corresponding to the neck region 21 expands outward under air pressure, while the tensioning bands 5 exert inward pulling forces on the sleeping mat layer 2 along an opposite direction, so that a protruding strip 211 that extends continuously along the lateral direction is formed on the corresponding portion of the sleeping mat layer 2 between adjacent tensioning bands 5. In this manner, a plurality of protruding strips 211 that extends continuously along the lateral direction is formed in the neck region 21, and the height of each protruding strip 211 remains unchanged along the lateral direction.
According to the present invention, the vertical heights of the protruding strips 211 in the inflated state can be adjusted by adjusting the vertical heights of the tensioning hands 5 in the neck region 21, or by adjusting the longitudinal distance between two adjacent tensioning bands 5 corresponding to the neck region 21. In this manner, the vertical height of the neck region 21 can be adjusted. Preferably, the longitudinal distances between the plurality of tensioning bands 5 corresponding to the neck region 21 are configured to be the same, so that the plurality of protruding strips 211 corresponding to the neck region 21 has the same height.
According to the present invention, the tensioning bands 5 corresponding to the back region 22 are fixedly bonded with the sleeping mat layer 2 and the ground mat layer 3 along the lateral direction in a continuous manner, thereby forming a plurality of protruding strips 211 that extends continuously along the lateral direction in the back region 22 of the sleeping mat layer 2. Further, a middle area of the back region 22 is configured to be lower than areas on both sides thereof along the lateral direction, so that the back region 22 has a structure with a concave middle area along the lateral direction. In this manner, the back region 22 is shaped as a concave cavity that closely fits the back of the human body, and thus can effectively relive the stress on the back of the human body.
In one embodiment, a lateral middle portion of a plurality of tensioning bands 5 in the back region 22 is configured to be lower than both lateral sides thereof along the vertical direction. That is, the back region 22 has a structure with a lower middle portion and two higher sides. In the inflated state, the portion of the sleep mat layer 2 corresponding to the back region 22 form a plurality of protruding strips that extends continuously along the lateral direction under the influence of air pressure and the tensioning bands 5. In addition, the lateral middle portion of each protruding strip is configured to be lower than the corresponding two lateral sides along the vertical direction, so that the back region 22 is shaped as a concave cavity that closely fits the back of the human body.
According to the present invention, the vertical heights of the protruding strips in the inflated state can be adjusted by adjusting the vertical heights of the tensioning bands 5 corresponding to the back region 22, or by adjusting the longitudinal distance between two adjacent tensioning bands 5 corresponding to the back region 22. In this manner, the vertical height of the back region 22 can be adjusted. Preferably, the longitudinal distances between the plurality of tensioning bands 5 corresponding to the back region 22 are configured to be the same, so that the plurality of protruding strips corresponding to the back region 22 has the same height.
According to the present invention, as shown in FIG. 5 , the vertical height of the neck region 21 is configured to be greater than the maximum vertical height of the back region 22, causing a height difference between the neck region 21 and the back region 22. This structure of the neck region 21 is able to support the head of the human body. That is, the neck region 21 can be used as a headrest support, thereby making the head feel comfortable and further improving the convenience of the ergonomic sleeping mat too. At the same time, the height difference between the back region 22 and the neck region 21 is more remarkable due to the concave structure in the laterally middle portion of the back region 22, so that the neck region 21 is more applicable as a pillow.
According to the present invention, the waist region 23 is configured to have a constant height along the lateral direction. Similarly, the tensioning bands 5 corresponding to the waist region 23 are fixedly bonded to the sleeping mat layer 2 and the ground mat layer 3 along the lateral direction in a continuous manner, thereby forming a plurality of protruding strips extending continuously along the lateral direction in the waist region 23 of the sleeping mat layer 2.
In one embodiment, the plurality of tensioning bands 5 corresponding to the waist region 23 are configured to have the same vertical height, wherein the vertical height of each tensioning band 5 remains unchanged along the lateral direction. In the inflated state, a plurality of protruding strips extending continuously along the lateral direction is formed in the portion of the sleeping mat layer 2 corresponding to the waist region 23 under the influence of air pressure and the tensioning bands 5, wherein the height of each protruding strip remains unchanged along the lateral direction.
Similarly, the vertical heights of the protruding strips in the inflated state can be adjusted by adjusting the vertical heights of the tensioning bands 5 corresponding to the waist region 23, or by adjusting the longitudinal distance between two adjacent tensioning bands 5 corresponding to the waist region 23. In this manner, the vertical height of the waist region 23 can be adjusted. Preferably, the longitudinal distances between the plurality of tensioning bands 5 corresponding to the waist region 23 are configured to be the same, so that the plurality of protruding strips corresponding to the waist region 23 has the same height.
According to one embodiment of the present invention, as shown in FIG. 5 , the waist region 23 is configured to be higher than the back region 22 and the leg region 24, so that the waist region 23 is able to be in contact with the waist of the human body to support the waist. This enables the waist to be stretched, thereby effectively relieving pressure on the waist of the human body, and making the user feel more comfortable, which is very conducive to the pressure relieving effect of the ergonomic sleeping mat 100.
According to the present invention, the tensioning bands 5 corresponding to the leg region 24 and spaced from each other evenly along the lateral direction are fixedly bonded to the sleeping mat layer 2 and the ground mat layer 3, thereby forming undulating bulges 241 (see FIG. 6 ) extending along the lateral direction in the leg region 24.
In one embodiment, the vertical heights of the plurality of tensioning bands 5 corresponding to the leg region 24 are configured to be the same, wherein the vertical height of each tensioning band 5 remains unchanged along the lateral direction. In the inflated state, the portion of the sleeping mat layer 2 corresponding to the leg region 24 expands outwardly under air pressure, while the tensioning bands 5 exert inward pulling forces on the sleeping mat layer 2 along an opposite direction at the fixedly bonding positions to the sleeping mat layer 2 and the ground mat layer 3, thereby forming undulating bulges 241 extending continuously along the lateral direction in the corresponding portion of the sleeping mat layer 2 between adjacent tensioning bands 5. Therefore, a plurality of undulating bulges 241 extending continuously along the lateral direction is formed in the leg region 24. In this manner, a plurality of convex contact surfaces and undulating curves are formed in the corresponding leg region 24 of the sleeping mat layer 2, which are well adapted for the natural curve of human body in a supine position, and conform to ergonomics, so that the user can place his or her legs more comfortably.
Similarly, the vertical heights of the undulating bulges 241 in the inflated state can be adjusted by adjusting the vertical heights of tensioning bands 5 corresponding to the leg region 24, or by adjusting the longitudinal distance between two adjacent tensioning bands 5 corresponding to the leg region 24. In this manner, the vertical height of the leg region 24 can be adjusted. Preferably, the longitudinal distances between the plurality of tensioning bands 5 corresponding to the leg region 24 are configured to be the same, so that the plurality of undulating bulges 241 corresponding to the leg region 24 has the same height.
According to the present invention, the height of the ankle region 25 is configured to remain unchanged along the lateral direction. Similarly, along the lateral direction, the tensioning bands 5 corresponding to the ankle region 25 are fixedly bonded to the sleeping mat layer 2 and the ground mat layer 3 in a continuous manner, so that protruding strips extending continuously along the lateral direction are formed in the ankle region 25 of the sleeping mat layer 2.
In one embodiment, the vertical heights of the plurality of tensioning bands 5 corresponding to the ankle region 25 are configured to be the same, wherein the vertical height of each tensioning band 5 remains unchanged along the lateral direction. In the inflated state, the plurality of protruding strips extending continuously along the lateral direction are formed in the portion of the sleeping mat layer 2 corresponding to the ankle region 25 under the influence of air pressure and the tensioning bands 5, wherein the height of each protruding strip remains unchanged along the lateral direction. This structure of the ankle region 25 provides less undulating curves, which is well adapted for the natural curve of human body in a supine position, and conforms to ergonomics, so that the user can place his or her ankles more comfortably.
Similarly, the vertical heights of the protruding strips in the inflated state can be adjusted by adjusting the vertical heights of tensioning bands 5 corresponding to the ankle region 25, or by adjusting the longitudinal distance between two adjacent tensioning bands 5 corresponding to the ankle region 25. In this manner, the vertical height of the ankle region 25 can be adjusted. Preferably, the longitudinal distances between the plurality of tensioning bands 5 corresponding to the ankle region 25 are configured to be the same, so that the plurality of protruding strips corresponding to the ankle region 25 has the same height.
According to one embodiment of the present invention, the tensioning bands 5 corresponding to the neck region 21, the back region 22, the waist region 23, the leg region 24, and the ankle region 25 are all configured to be distributed evenly at a certain distance along the longitudinal direction. In one embodiment, the longitudinal spacing of the tensioning bands 5 corresponding to the neck region 21 and the back region 22 is configured, for example, as a first spacing, and the longitudinal spacing of the tensioning bands 5 corresponding to the waist region 23, the leg region 24 and the ankle region 25 is configured, for example, as a second spacing, wherein the second spacing is configured to be greater than the first spacing. Based on the above structure, the protruding strips corresponding to the neck region 21 and the back region 22 that carry the main weight of the human body are distributed densely, thus providing greater rigid support. At the same time, the protruding strips or the undulating bulges corresponding to the waist region 23, the leg region 24 and the ankle region 25 that carry the weight of lower limbs of the human body are distributed sparsely, thus providing smaller rigid support. Therefore, the sleeping mat layer 2 is suitable for different parts of human body, thus effectively enhancing the pressure relieving effect in various parts.
Of course, it should be understood that the density of the longitudinal distribution of the tensioning bands 5 corresponding to the neck region 21, the back region 22, the waist region 23, the leg region 24, and the ankle region 25 may also be configured independently according to actual needs. For example, the longitudinal spacing of the tensioning bands 5 corresponding to the neck region 21, the back region 22, the waist region 23, the leg region 24, and the ankle region 25 may all be configured differently. As a result, as shown in FIG. 6 , the neck region 21, back region 22, waist region 23, leg region 24, and ankle region 25 on the sleeping mat layer 2 are configured as human body contact surfaces with different heights and undulating shapes.
According to the present invention, the undulating human body contact surfaces formed by the neck region 21, back region 22, waist region 23, leg region 24 and ankle region 25 on the sleeping mat layer 2 have height differences ranging from 0.5-4 centimeters. Due to the undulations of the human body contact surfaces of the sleeping mat layer 2, the structure of the ergonomic sleeping mat 100 is more ergonomic, which can make the human body more comfortable, further relieve the pressure on various parts of the human body, and significantly improve the quality of sleep.
The ergonomic sleeping mat 100 according to the present invention is provided with tensioning bands 5 with different heights in regions corresponding to different parts of the human body. In an inflated state, regions of the sleeping mat layer 2 of the sleeping mat body 1 corresponding to different parts of the human body are formed as human body contact surfaces with different heights and convex/concave shapes, so that the sleeping mat layer 2 is endowed with enhanced undulating effect. Accordingly, the sleeping mat layer 2 of the ergonomic sleeping mat 100 conforms to ergonomics better in structure, and is very conducive to significantly and effectively relieving pressure on the neck, back, waist, legs, ankles, and other parts of the body, thus achieving a soothing effect. Therefore, the quality of sleep can be effectively improved, and the user can feel more comfortable. In addition, the ergonomic sleeping mat 100 is portable because it has a light weight and can be folded conveniently.
