Structural support shoe and method of manufacturing the same

Claim 2

A shoe for a structural support comprising: a pair of rigid angular parts, each including a base member and a side member extending integrally therefrom at an angle thereto; the base member of one part being positioned in cooperative relation with respect to the base member of the other part with the side members of each part extending in opposed facing spaced relation to each other; and, means to join said base members in fast reinforcing relation to form said shoe.

Claim 3

The shoe of claim 1, said base members of said angular parts being positioned in overlapping relationship.

Claim 4

The shoe of claim 1, said angular parts being of extruded material.

Claim 5

The shoe of claim 1, said angular parts being of extruded aluminum material.

Claim 6

The shoe of claim 1, said members of said angular parts including selectively spaced punched holes.

Claim 7

The shoe of claim 1, said base members of said angular parts being riveted together.

Claim 8

The shoe of claim 1, said base members of said angular parts being welded together.

Claim 9

The shoe of claim 1, said base members of said angular parts being staked together.

Claim 10

The shoe of claim 1, said base members of said angular parts including offset portions which interlock with each other.

Claim 11

The shoe of claim 1, one angular part having a portion of its side member extending beyond its base member a distance equal to the thickness of said parts; said base members of said parts being in overlapping position with respect to each other with the outer base member edge abutting said extended portion of said other base member.

Claim 12

The shoe of claim 1, at least one base member having a traction surface on the outer face thereof.

Claim 13

The shoe of claim 1, said base members being spiked at one end thereof.

Claim 14

A shoe for a ladder foot comprising: a pair of extruded aluminum angular parts of uniform thickness, each including a flat base member and a side member extending integrally therefrom at a right angle thereto with one side member extending beyond its base member a distance equal to the thickness of said parts; said base members of said parts including offset portions and being in overlapped position with the offset portions thereof interlocking and with the outer base member edge abutting said extended portion of said other base member; said base members being spiked at one end thereof and including matching holes; a traction gridded rubber sole facing said outer base member and having matching holes with said overlapping base members; and, rivets passing through said holes to join said overlapping base members and said traction gridded rubber sole together with said side members of said parts in spaced opposed relation to form said shoe; said side members having mating holes to receive a pin for connection to said ladder foot.

Claim 15

A shoe for a ladder foot comprising: a pair of extruded aluminum angular parts of uniform thickness, each including a flat base member and a side member extending integrally therefrom at a right angle thereto with one side member extending beyond its base member a distance equal to the thickness of said parts; said base members of said parts including offset portions and being in overlapped position with the offset portions thereof interlocking and with the outer base member edge abutting said extended portion of said other base member; said base members being spiked at one end thereof and including matching holes; a traction gridded rubber sole facing said outer base member and having matching holes with said overlapping base members; and, rivets passing through said holes to join said overlapping base members and said traction gridded rubber sole together with said side members of said parts in spaced opposed relation to form said shoe; said side members having mating holes to receive a pin for connection to said ladder foot.
