- 1. Field of the Invention
- The invention relates to an inflatable bed, more particularly to an inflatable bed having a simple structure and sufficient structural strength.
- 2. Description of the Related Art
- As shown in
FIG. 1 , a conventional inflatable bed includes atop sheet 40, abottom sheet 42 spaced apart from thetop sheet 40, amiddle sheet 41 parallel to and disposed between the top andbottom sheets sheet 43 having atop sheet portion 430 that interconnects peripheries of the top andmiddle sheets middle sheets lower sheet portion 431 that is connected to thetop sheet portion 430, that interconnects peripheries of the middle andbottom sheets bottom sheets upper pull belts 51 disposed in the upper inflatable space, and a plurality oflower pull belts 52 disposed in the lower inflatable space. Each of theupper pull belts 51 has vertically opposite top and bottom edges that are connected respectively to the top andmiddle sheets lower pull belts 52 has vertically opposite top and bottom edges that are connected respectively to the middle andbottom sheets middle sheet 41 results in a double-layer structure of the conventional inflatable bed, and the upper andlower pull belts middle sheet 41 and the surroundingsheet 43, theupper pull belts 51 and the top andmiddle sheets lower pull belts 52 and the middle andbottom sheets - Therefore, the object of the present invention is to provide an inflatable bed that has a multilayer appearance, a relatively simple structure and sufficient structural strength.
- Accordingly, an inflatable bed of the present invention comprises a top sheet, a bottom sheet, an endless surrounding belt, and a plurality of pull belts. The surrounding belt interconnects peripheries of the top and bottom sheets, and cooperates with the top and bottom sheets to define an inflatable space thereamong. The surrounding belt has a bow tie shaped cross-section and includes vertically opposite upper and lower hollow portions. The upper hollow portion has a first surrounding surface that confronts the inflatable space and that is connected to the periphery of the top sheet. The lower hollow portion has a second surrounding surface that confronts the inflatable space and that is connected to the periphery of the bottom sheet. The pull belts are disposed in the inflatable space. Each of the pull belts has opposite top and bottom edges that are connected respectively to the top and bottom sheets.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
-
FIG. 1 is a partly cutaway perspective view of a conventional inflatable bed; -
FIG. 2 is a partly cutaway perspective view of a first preferred embodiment of an inflatable bed according to the invention; -
FIG. 3 is a sectional view of the first preferred embodiment; and -
FIG. 4 is a fragmentary, partly sectional, perspective view of a second preferred embodiment of the inflatable bed according to the invention. - Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
- As shown in
FIGS. 2 and 3 , the first preferred embodiment of an inflatable bed according to the present invention comprises a top sheet 1, abottom sheet 2, an endless surroundingbelt 3, and a plurality ofpull belts 51. - The top and
bottom sheets 1, 2 are disposed parallel to each other. - The surrounding
belt 3 interconnects peripheries of the top andbottom sheets 1, 2, and cooperates with the top andbottom sheets 1, 2 to define aninflatable space 500 thereamong. The surroundingbelt 3 has a bow tie shaped cross-section and includes vertically opposite upper and lowerhollow portions hollow portions hollow portion 31 of the surroundingbelt 3 has atop wall 301, abottom wall 300 disposed under and shorter than thetop wall 301, an inner surroundingwall 302 interconnecting inner peripheries of the top andbottom walls surface 3021 that confronts theinflatable space 500 and that is connected to the periphery of the top sheet 1, and an outer surroundingwall 303 interconnecting outer peripheries of the top andbottom walls wall 302 of the upperhollow portion 31. The lowerhollow portion 32 of the surroundingbelt 3 has atop wall 304 coupled to thebottom wall 300 of the upperhollow portion 31 of the surroundingbelt 3, abottom wall 305 disposed under and wider than thetop wall 304, an inner surroundingwall 306 interconnecting inner peripheries of the top andbottom walls surface 3061 that confronts theinflatable space 500 and that is connected to the periphery of thebottom sheet 2, and an outer surroundingwall 307 interconnecting outer peripheries of the top andbottom walls wall 306 of the lowerhollow portion 32. In this embodiment, the periphery of the top sheet 1 is connected to the first surroundingsurface 3021 of the inner surroundingwall 302 of the upperhollow portion 31 of the surroundingbelt 3 at a position adjacent to thetop wall 301 of the upperhollow portion 31, and the periphery of thebottom sheet 2 is connected to the second surroundingsurface 3061 of the inner surroundingwall 306 of the lowerhollow portion 32 of the surroundingbelt 3 at a position adjacent to thebottom wall 305 of the lowerhollow portion 32. - The
pull belts 51 are disposed in theinflatable space 500 and are parallel to each other. Each of thepull belts 51 has vertically opposite top and bottom edges that are connected respectively to the top andbottom sheets 1, 2. Thepull belts 51 provide sufficient structural strength when the inflatable bed is inflated. - Although this preferred embodiment of the inflatable bed has a double-layer appearance, it has a simpler structure than that of the aforementioned prior art by omitting the
middle sheet 42. Moreover, since each of thepull belts 51 is connected directly to the top andbottom sheets 1, 2, the process of connecting thepull belts 51 to the top andbottom sheets 1, 2 is simpler than that of the prior art, thereby resulting in a lower manufacturing cost of the inflatable bed of this invention. Furthermore, when the inflatable bed of this embodiment is inflated, thetop wall 301 of the upperhollow portion 31 of the surroundingbelt 3 will slightly swell out to serve as a bed rail around the top sheet 1, thereby enhancing safety of the inflatable bed of this invention. - Referring to
FIG. 4 , the second preferred embodiment of the inflatable bed according to the present invention has a structure similar to that of the first embodiment. The main difference between this embodiment and the previous embodiment resides in the configuration of the surroundingbelt 3. The surroundingbelt 3 of this embodiment includes vertically opposite upper and lowerhollow portions 31′, 32′. The upperhollow portion 31′ of the surroundingbelt 3 is in a form of an endless tube, and includes a generally V-shapedfirst plate 34 and atop plate 33. Thefirst plate 34 has amiddle segment 346, an inner surroundingsegment 341 extending from a side of themiddle segment 346 and formed with a first surroundingsurface 3021′ to which the top sheet 1 is coupled, and an outer surroundingsegment 342 extending from an opposite side of themiddle segment 346. Thetop plate 33 is coupled to upper ends of the inner and outer surroundingsegments first plate 34. The lowerhollow portion 32′ of the surroundingbelt 3 is also in a form of an endless tube, and includes a generally inverted V-shapedsecond plate 36 and abottom plate 37. Thesecond plate 36 has amiddle segment 366 coupled to themiddle segment 346 of thefirst plate 34 of the upperhollow portion 31′ of the surroundingbelt 3, an inner surroundingsegment 361 extending from a side of themiddle segment 366 and formed with a second surroundingsurface 3061′ to which thebottom sheet 2 is coupled, and an outer surroundingsegment 362 extending from an opposite side of themiddle segment 366. Thebottom plate 37 is coupled to lower ends of the inner and outer surroundingsegments second plate 36. The second preferred embodiment has the same advantages as those of the first preferred embodiment. - While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
