Abstract
Abstract A tunnel formed of a thermoplastic film with an outside and inside surface with compressed air in between. The tunnel consists of end sections (20) connected by longitudinal sections (22) to support sections (24), each having openings therebetween, allowing communication for introducing the compressed air. A second embodiment is similar, except it utilizes helical shaped sections (34) formed in a round configuration. A polygon shaped center intersection (40) connects the tunnels together with hook and loop tape (28) bonded to each mating surface forming a matrix when used in conjunction with a plurality of tunnels and intersections. The hollow interior of the devices allow children at play to enter and crawl through while within the protective enclosure afforded by the invention.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
An inflatable toy tunnel comprising: (a) a first and second quadrangularly shaped end each having an outside and inside wall with compressed air therebetween forming a collapsible structure; (b) a plurality of longitudinal sections having an outside and inside wall with compressed air therebetween attached to said first and second end with communication therein; (c) a plurality of quadrangularly shaped supports having an outside and inside wall with compressed air therebetween communicably abutting said longitudinal sections forming a segmented tunnel with a clear passageway therethrough, allowing entrance and egress for children at play; (d) a plurality of ground attaching loops at the lower extremes of said tunnel for fastening to the surface upon which the tunnel is resting; and, (e) connecting means on the exposed outside surface of said ends for attachment to a like structure for lengthening and the creation of an assembled matrix, said connecting means comprising continuous strips of hook and loop tape bonded to said ends with adhesive forming a removable and reusable joining system.
Claim 2
Dependent Claim
