Inflatable pad assembly

Abstract

An inflatable pad assembly includes a connecting unit for interconnecting pivotally and detachably first and second inflatable pads such that the second inflatable pad is operable so as to pivot relative to the first inflatable pad between a first position, where one of opposite first and second sides of the first inflatable pad abuts against one of opposite first and second sides of the second inflatable pad, and a second position, where the second inflatable pad is superposed on the first inflatable pad. A third inflatable pad is connected pivotally to the second inflatable pad, and is operable so as to pivot relative to the second inflatable pad between a third position, where the third inflatable pad is received fittingly in a notch in the first side of the second inflatable pad, and a fourth position, where the third inflatable pad is superposed on the second inflatable pad.

Claims

1. An inflatable pad assembly comprising: a first inflatable pad having opposite first and second sides;a second inflatable pad having a first side formed with a notch, and a second side opposite to said first side of said second inflatable pad;a connecting unit for interconnecting pivotally and detachably said first and second inflatable pads such that said second inflatable pad is operable so as to pivot relative to said first inflatable pad between a first position, where one of said first and second sides of said first inflatable pad abuts against one of said first and second sides of said second inflatable pad, and a second position, where said second inflatable pad is superposed on said first inflatable pad; anda third inflatable pad connected pivotally to said second inflatable pad and operable so as to pivot relative to said second inflatable pad between a third position, where said third inflatable pad is received fittingly in said notch in said first side of said second inflatable pad, and a fourth position, where said third inflatable pad is superposed on said second inflatable pad.

2. The inflatable pad assembly as claimed in claim 1, wherein, when said second inflatable pad is disposed at the first position and when said third inflatable pad is disposed at the third position, said inflatable pad assembly serves as a single-layer bed.

3. The inflatable pad assembly as claimed in claim 1, wherein, when said second inflatable is disposed at the second position and when said third inflatable pad is disposed at the third position, said inflatable pad assembly serves as a two-layer folded bed.

4. The inflatable pad assembly as claimed in claim 1, wherein, when said second inflatable pad is disposed at the second position and when said third inflatable pad is disposed at the fourth position, said inflatable pad assembly serves as a sofa.

5. The inflatable pad assembly as claimed in claim 4, wherein said second inflatable pad has a mounting surface abutting against said third inflatable pad when said second and third inflatable pads are disposed respectively at the second and fourth positions, said mounting surface being formed with a cup-receiving groove that is disposed adjacent to said notch.

6. The inflatable pad assembly as claimed in claim 1, wherein said connecting unit includes a pair of opposite snap fastener units, each of which includes a female fastener disposed on one of said first sides of said first and second inflatable pads, a strap fastened to the other one of said first sides of said first and second inflatable pads, and a male fastener disposed fixedly on said strap and engaging detachably said female fastener such that said second side of said second inflatable pad is moved toward said second side of said first inflatable pad when said second inflatable pad is pivoted from the first position to the second position.

7. The inflatable pad assembly as claimed in claim 1, wherein said connecting unit includes a zipper that has two zipper halves disposed respectively on said second sides of said first and second inflatable pads and engaging detachably each other such that said first side of said second inflatable pad is moved toward said first side of said first inflatable pad when said second inflatable pad is pivoted from the first position to the second position.

8. The inflatable pad assembly as claimed in claim 1, wherein said notch in said first side of said second inflatable pad is defined by a wall, said second inflatable pad including a first flap fastened to said wall, said third inflatable pad including a second flap fastened to a side thereof and connected fixedly to said first flap of said second inflatable pad, thereby allowing pivoting movement of said third inflatable pad about an assembly of said first and second flaps.

9. The inflatable pad assembly as claimed in claim 1, wherein said notch in said first side of said second inflatable pad is defined by a wall, said second inflatable pad including a first flap that is fastened to said wall and that is provided with a hook-and-loop fastener, said third inflatable pad including a second flap that is fastened to a side thereof and that is provided with a hook-and-loop fastener, said hook-and-loop fasteners of said first and second flaps engaging detachably each other so as to interconnect said first and second flaps, thereby allowing pivoting movement of said third inflatable pad about an assembly of said first and second flaps.

10. The inflatable pad assembly as claimed in claim 1, wherein, when said third inflatable pad is disposed at the third position, an assembly of said second and third inflatable pads is rectangular and has a size substantially equal to that of said first inflatable pad.
