Abstract

An inflatable device includes an upper layer, a lower layer, and at least one strap alternately connected to the upper layer and the lower layer to form a wavelike pattern between the upper layer and the lower layer so as to limit deformation of both the upper layer and the lower layer. The strap includes a plurality of first contact portions connected to the upper layer, and a plurality of second contact portions connected to the lower layer. The first contact portions are offset from the second contact portions in a horizontal plane respectively defined by the upper layer and the lower layer, such that the first contact portions are not superimposed with the second contact portions from a perspective orthogonal to the upper and lower layers.

Claims

1. An inflatable device comprising:

an upper layer;

a lower layer; and

at least one strap alternately connected to the upper layer and the lower layer to form a wavelike pattern between the upper layer and the lower layer so as to limit deformation of both the upper layer and the lower layer.

2. The inflatable device as claimed in claim 1, wherein the strap comprises a plurality of first contact portions connected to the upper layer, and a plurality of second contact portions connected to the lower layer, wherein the first contact portions are offset from the second contact portions in a horizontal plane respectively defined by the upper layer and the lower layer, such that the first contact portions are not superimposed with the second contact portions from a perspective orthogonal to the upper and lower layers.

3. The inflatable device as claimed in claim 1, comprising a plurality of straps, wherein the straps are arranged longitudinally with respect to the upper layer and the lower layer.

4. The inflatable device as claimed in claim 1, comprising a plurality of straps, wherein the straps are arranged latitudinally with respect to the upper layer and the lower layer.

5. The inflatable device as claimed in claim 1, wherein the upper layer has an inner surface area, and a total contact area between the strap and the inner surface area as a percentage of the inner surface area is equal to or larger than 6.3%.

6. The inflatable device as claimed in claim 5, wherein the total contact area between the strap and the inner surface area as a percentage of the inner surface area is less than or equal to 63%

7. The inflatable device as claimed in claim 1, wherein the lower layer has an inner surface area, and a total contact area between the strap and the inner surface area as a percentage of the inner surface area is equal to or larger than 6.3%.

8. The inflatable device as claimed in claim 7, wherein the total contact area between the strap and the inner surface area as a percentage of the inner surface area is less than or equal to 63%.

9. The inflatable device as claimed in claim 1, wherein the lower layer is provided with a protruding peripheral edge formed on an underside of the lower layer arranged to establish a suction force with a surface on which the inflatable device is disposed.

10. The inflatable device as claimed in claim 9, wherein an auxiliary strap is provided between an exterior surface of the lower layer and an inner sidewall of the protruding peripheral edge.

11. The inflatable device as claimed in claim 1, wherein an auxiliary strap is provided between an inner surface of the sidewall and an inner surface of the lower layer.

12. The inflatable device as claimed in claim 1, wherein a first auxiliary bar is provided at a joint between the upper layer and the sidewall and a second auxiliary bar is provided at a joint between the sidewall and the lower layer to enhance integrity of both the upper layer and the lower layer.

13. The inflatable device as claimed in claim 1, wherein portions of the strap extending between the upper and lower layer are slanted with respect to a reference line orthogonal to the upper layer and the lower layer.

14. The inflatable device as claimed in claim 1, wherein the strap is a single, continuous strip of material.

15. The inflatable device as claimed in claim 1, wherein the strap comprises a plurality of individual strips connected between the upper and lower layers.

16. The inflatable device as claimed in claim 1, wherein an angle measured between a portion of the strap forming a contact portion connected to the upper layer and a segment of the strap extending from the contact portion to the lower layer is between 91 and 167 degrees.

17. The inflatable device as claimed in claim 1, wherein an angle measured between a portion of the strap forming a contact portion connected to the lower layer and a segment of the strap extending from the contact portion to the upper layer is between 91 and 167 degrees.
