Fence and wall structures

Claim 2

A portable fence-type enclosure comprising a plurality of separate building modules having means interlocking said modules to form a continuous wall, means carried by at least some of said building modules of said wall on at least one side thereof to retain and support inflatable means which when inflated exert pressure directly against said wall to expand same outwardly, thereby applying tension between said interlocked building modules for maintaining said wall in place.

Claim 3

In the enclosure defined in claim 1, said building modules comprising plates and said hinge means comprising hook and eyes to separably attach said plates one to another to form a substantially circular enclosure.

Claim 4

In the enclosure defined in claim 1, said hinge means comprising a pivotable and slidable rail and channel interlock to separably attach said plates one to another to form a completely closed enclosure.

Claim 5

In the enclosure defined in claim 2, said plates having opposed ledge means formed integral therewith and adapted to overlap in the assembly with complementary ledge means of adjacent plates to form a closed enclosure.

Claim 6

In the enclosure defined in claim 1, said retainer means comprising hooks and said inflatable means comprising at least one pneumatic tube adapted to be supported in the assembly by said hooks on some of said plates.

Claim 7

The enclosure defined in claim 5, in which said means to inflate said tube comprise valve means attached to said tubes.

Claim 8

In the enclosure defined in claim 2, said plates being made of expanded metal.

Claim 9

In the enclosure defined in claim 2, said plates being made of perforated sheet material.

Claim 10

In the enclosure defined in claim 2, said plates being made of corrugated sheet material.

Claim 11

In the enclosure defined in claim 1, said plates being made of fire and bulletproof material.

Claim 12

In the enclosure defined in claim 3, said plates being provided with portholes.

Claim 13

In the enclosure defined in claim 3, said rail and channel interlock extending along the sides of said plates from end to end to allow vertical adjustment of said plates relative to each other upon assembly of said enclosure on a rough terrain.

Claim 14

A portable collapsible enclosure comprising in assembly: plates of identical configuration adapted to form a circular wall, when assembled; hinge means associated with each of said plates to lock said plates together to form said circular wall; pneumatic means associated with each of said plates adapted to exert equal pressure directly on each of said plates when actuated for maintaining said wall in place; and means to retain said pneumatic means on said plates when assembled to form an enclosure.

Claim 15

A portable collapsible enclosure comprising in assembly: plates of identical configuration adapted to form a circular wall, when assembled; hinge means associated with each of said plates to lock said plates together to form said circular wall; pneumatic means associated with each of said plates adapted to exert equal pressure directly on each of said plates when actuated for maintaining said wall in place; and means to retain said pneumatic means on said plates when assembled to form an enclosure.

Claim 16

In the portable collapsible enclosure as defined in claim 13, said pneumatic means comprising a pair of inflatable tubes spaced in parallel relationship and adapted to abut all of said plates of said circular wall to exert equal pressure on each of said plates when inflated.

Claim 17

In the portable collapsible enclosure as defined in claim 14, the provision of shields placed over the exposed portions of said pair of inflatable tubes between said retaining means, and tongues stamped out of the material of said plates adjacent said retaining means adapted to securely clamp said shields to said inflatable tubes.

Claim 18

In the portable collapsible enclosure as defined in claim 13, said plates being solid and provided with portholes.

Claim 19

In the portable collapsible enclosure as defined in claim 13, said plates being curvilinear to form a true circle when assembled.

Claim 20

A portable collapsible enclosure comprising in assembly: plates of identical configuration adapted to form a circular wall, when assembled; hinge means associated with each of said plates to lock said plates together to form said circular wall; a pair of inflatable tubes spaced in parallel relationship and adapted to abut all of said plates of said circular wall to exert equal pressure on each of said plates when inflated; means to retain said pair of tubes on said plates when assembled to form an enclosure; and a gate in said enclosure and shield means adapted to be placed over the exposed portion of the lower one of said pair of inflatable tubes defined by the gate opening to protect said tube from damage.

Claim 21

A portable collapsible enclosure comprising in assembly: plates of identical configuration adapted to form a circular wall, when assembled; hinge means associated with each of said plates to lock said plates together to form said circular wall; a pair of inflatable tubes spaced in parallel relationship and adapted to abut all of said plates of said circular wall to exert equal pressure on each of said plates when inflated; means to retain said pair of tubes on said plates when assembled to form an enclosure; and a gate in said enclosure and shield means adapted to be placed over the exposed portion of the lower one of said pair of inflatable tubes defined by the gate opening to protect said tube from damage.

Claim 22

A portable collapsible enclosure comprising in assembly: plates of identical configuration adapted to form a circular wall, when assembled; hinge means associated with each of said plates to lock said plates together to form said circular wall; a pair of inflatable tubes spaced in parallel relationship and adapted to abut all of said plates of said circular wall to exert equal pressure on each of said plates when inflated; means to retain said pair of tubes on said plates when assembled to form an enclosure; and shields placed over the exposed portions of said pair of inflatable tubes between said retaining means.

Claim 23

A portable collapsible enclosure comprising in assembly: plates of identical configuration adapted to form a circular wall, when assembled; hinge means associated with each of said plates to lock said plates together to form said circular wall; a pair of inflatable tubes spaced in parallel relationship and adapted to abut all of said plates of said circular wall to exert equal pressure on each of said plates when inflated; means to retain said pair of tubes on said plates when assembled to form an enclosure; and shields placed over the exposed portions of said pair of inflatable tubes between said retaining means.
