Patent Application
20190069691
The present invention relates to an inflatable bed, and more particularly to a connecting structure of an inflatable bed.
For mountaineering or camping, people usually use a soft cushion to enhance the comfort of ling on the ground and stop the surface temperature. The soft cushion is made of a soft material, so it can enhance the comfort for the user to lie thereon. But, because of its solid structure, the soft cushion is heavy in weight and large in size, so it is inconvenient for carrying. Therefore, an inflatable mattress is developed on the market. Although it can reduce the weight and the size after collapsed, the internal structure of the inflatable mattress is provided with a number of pull strips. As a result, the inflatable mattress is still somewhat heavy.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
In view of the shortcomings of the prior art, the primary object of the present invention is to provide an inflatable bed which is light in weight and comfortable for use and has a simple structure and can be carried conveniently and has a low cost and other advantages, meeting the needs of industry and consumers.
In order to achieve the aforesaid object, the inflatable bed of the present invention comprises an upper body, a lower body, and a closed chamber space formed between the upper body and the lower body. The inflatable bed includes a plurality of connecting members therein. The connecting members are spaced a determined distance apart from each other and arranged longitudinally and transversely inside the inflatable bed for connecting the upper body with the lower body. Each of the connecting members is a thin ring-like structure. When the chamber space inside the inflatable bed is inflated, the connecting members arranged in the longitudinal and transverse directions provide a bubble-like effect, thereby enhancing the comfort for the user to lie on the inflatable bed. Further, the inflatable bed is light and small in size after collapsed, which is advantageous for camping and mountaineering.
Preferably, the upper body and each of the connecting members are joined together by a press-fit technique, such as high frequency heating, to form a bonded portion so that the upper body is connected with the connecting member.
Preferably, the lower body and each of the connecting members are joined together by a press-fit technique, such as high frequency heating, to form a bonded portion so that the lower body is connected with the connecting member.
Preferably, the bonded portion may be of various shapes, such as a circle, a rectangle, a strip, or a polygon, but not limited thereto.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
As shown in
Each connecting member 2 is a thin ring-like structure. The upper body 11 and the connecting member 2 are joined together by a press-fit technique, such as high frequency heating, to form a bonded portion 13 so that the upper body 11 is connected with the connecting member 2. The lower body 12 is connected with the connecting member 2 in the same manner.
According to the above-described structure, when the chamber space 10 inside the inflatable bed 1 is inflated, the connecting members 2 spaced a determined distance apart from each other and arranged longitudinally and transversely are inflated and connected between the upper body 11 and the lower body 12 to provide a bubble-like effect, thereby enhancing the comfort for the user to lie on the inflatable bed. Further, after the inside of the chamber space 10 is deflated (as shown in
The bonded portion 13 may be of various shapes, such as a circle. As shown in
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
