Abstract
Abstract A convertible device which may be formed into either a carrying bag or mattress comprises a plurality of panels extending from each side of a relatively narrow center panel, the panels being inflatable and hinged together. Side flaps having closure devices extend from the opposite ends of the center panel and at least one of the adjacent panels for joining the ends of the panels adjacent the center panel when forming a carrying bag. The center panel and side flaps provide increased width for the bag permitting increased capacity.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
200 words
An assembly for alternatively forming a bag or an elongated pad comprising: a. a pneumatically inflatable intermediate panel, b. pneumatically inflatable side panels hingedly secured to opposite transverse edges of said intermediate panel, c. at least two end flaps, one of said end flaps being attached along one side thereof to a lateral edge of at least one of said side panels and another of said end flaps being attached along one side thereof to the opposite lateral edge of at least one of said side panels, d. valve means for inflating said intermediate panel and separate further valve means for inflating said side panels, and e. releasable securing means along the opposite lateral edges of said assembly for securing each of the lateral edges together when said side panels are folded into parallel relationship to form said bag, f. said intermediate panel being separately inflatable from said side panels with no pneumatic communication between said intermediate panel and said side panels whereby when said assembly is formed as a bag, the weight of an article in said bag will not cause transfer of air contained in said intermediate panel to said side panels distorting the shape of said bag.
Claim 2
Dependent Claim
200 words
An assembly for alternatively forming a bag or an elongated pad comprising: a. a pneumatically inflatable intermediate panel, b. pneumatically inflatable side panels hingedly secured to opposite transverse edges of said intermediate panel, c. at least two end flaps, one of said end flaps being attached along one side thereof to a lateral edge of at least one of said side panels and another of said end flaps being attached along one side thereof to the opposite lateral edge of at least one of said side panels, d. valve means for inflating said intermediate panel and separate further valve means for inflating said side panels, and e. releasable securing means along the opposite lateral edges of said assembly for securing each of the lateral edges together when said side panels are folded into parallel relationship to form said bag, f. said intermediate panel being separately inflatable from said side panels with no pneumatic communication between said intermediate panel and said side panels whereby when said assembly is formed as a bag, the weight of an article in said bag will not cause transfer of air contained in said intermediate panel to said side panels distorting the shape of said bag.
Claim 3
Dependent Claim
27 words
The invention as defined in claim 1 wherein said securing means includes a zipper device having working elements positioned along the opposite lateral edges of said assembly.
Claim 4
Dependent Claim
27 words
The invention as defined in claim 1 comprising four end flaps which extend along each entire lateral edge of the intermediate panel and two adjacent side panels.
Claim 5
Dependent Claim
67 words
The invention as defined in claim 3 wherein each end flap is curved so as to joiN at the midpoint of the intermediate panel lateral edge, and said securing means comprises a zipper device having working elements connected along the outer edge of said end flaps whereby when the zipper elements are connected together two end flaps will be joined to form the ends of said bag.
Claim 6
Dependent Claim
16 words
The invention as defined in claim 1 wherein said end flaps are adapted to be inflated.
Claim 7
Dependent Claim
31 words
The invention as defined in claim 1 wherein said end flaps are connected along opposite lateral edges of one of said side panels which is positioned adjacent to said intermediate panel.
Claim 8
Dependent Claim
31 words
The invention as defined in claim 6 wherein said securing means is arranged along the outer edge of each of said end flaps, said intermediate panel and the opposite side panel.
Claim 9
Dependent Claim
55 words
The invention as defined in claim 1 wherein said end flaps are connected in offset fashion, one to the lateral edge of a side panel connected to one transverse edge of said intermediate panel and the other to the lateral edge of the side panel connected to the other transverse edge of said intermediate panel.
Claim 10
Dependent Claim
176 words
An assembly for alternatively forming a bag or elongated pad comprising: a. a pneumatically inflatable intermediate panel having a pair of opposite substantially parallel sides and at least one pneumatically inflatable side panel hingedly secured to each of said sides of said intermediate panel, said intermediate and side panels forming said assembly with a pair of opposite lateral sides transverse to the parallel sides of said intermediate panel, b. valve means for inflating said intermediate panel and separate valve means for inflating each of said side panels, and c. releasable securing means for securing each of said opposite lateral edges when said side panels are folded into substantially parallel spaced relationship to form said bag, d. said intermediate panel being separately inflatable from said side panels with no pneumatic communication between said intermediate panel and said side panels whereby when said assembly is formed as a bag, the weight of an article in said bag will not cause transfer of air contained in said intermediate panel to said side panels distorting the shape of said bag.
Claim 11
Dependent Claim
176 words
An assembly for alternatively forming a bag or elongated pad comprising: a. a pneumatically inflatable intermediate panel having a pair of opposite substantially parallel sides and at least one pneumatically inflatable side panel hingedly secured to each of said sides of said intermediate panel, said intermediate and side panels forming said assembly with a pair of opposite lateral sides transverse to the parallel sides of said intermediate panel, b. valve means for inflating said intermediate panel and separate valve means for inflating each of said side panels, and c. releasable securing means for securing each of said opposite lateral edges when said side panels are folded into substantially parallel spaced relationship to form said bag, d. said intermediate panel being separately inflatable from said side panels with no pneumatic communication between said intermediate panel and said side panels whereby when said assembly is formed as a bag, the weight of an article in said bag will not cause transfer of air contained in said intermediate panel to said side panels distorting the shape of said bag.
Claim 12
Dependent Claim
48 words
The invention as defined in claim 9 comprising a further separately pneumatically inflatable side panel hingedly secured to the side of each of said first recited side panels opposite said intermediate panel, whereby said further side panels may be deflated when said assembly is formed as a bag.
