Abstract

Abstract A key keeper is held in a belt loop within a small closed bend thereof. The keeper has opposed small and large half loops. Straight side rods connect the loops, being tangent to both. One side rod is split to place keys on the keeper. A trough or clip fixed to a rod at the split releasably secures the rod in place. One loop is about twice the diameter of the other, the large half loop imparting resiliency to the keeper to reduce the need for expensive spring steel wire for the keeper. The keeper is made by winding a continuous wire on a mandrel wherein two end plates with pivots support a large and a small arbor. Each arbor has a cylindrical outer segment in contact with the wire. A clamping bar holds the wire in place after winding, insuring that the wire accepts the shape of the arbors. A cutter then severs the strands of wire on one side of the mandrel, separating the wound length into segments each having the configuration set forth above.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 237 words
A key holder for use on a belt and comprising a belt hook formed by a pair of spaced flat legs joined by a shallow bend and adapted to retain the hook on the belt; a key keeper having a large half loop adapted to receive keys, a small half loop spaced from the large loop and engageable with the belt hook, a straight first keeper side rod connecting between said large and small keeper half loops, a discontinuous straight second keeper side rod connecting between the said large and small keeper half loops, and securing means for releasably securing together the discontinuous straight second keeper side rod, said securing means being fixedly attached to a portion of the discontinuous side near the small loop and further precluding passage of keys from the small loop at one end thereof; and means on the belt hook for retaining a key keeper including a flat loop extending from one spaced flat leg, a flat loop end bearing resiliently against said one spaced flat leg, and a flat leg extension on the other flat leg in contact with the outer surface of the loop and extending away from the shallow bend beyond the flat loop, whereby said key keeper is retained by said flat loop and said legs are resilient so as to spring apart to separate the flat loop and the leg for the insertion of a belt therebetween.
Claim 2
Dependent Claim 237 words
A key holder for use on a belt and comprising a belt hook formed by a pair of spaced flat legs joined by a shallow bend and adapted to retain the hook on the belt; a key keeper having a large half loop adapted to receive keys, a small half loop spaced from the large loop and engageable with the belt hook, a straight first keeper side rod connecting between said large and small keeper half loops, a discontinuous straight second keeper side rod connecting between the said large and small keeper half loops, and securing means for releasably securing together the discontinuous straight second keeper side rod, said securing means being fixedly attached to a portion of the discontinuous side near the small loop and further precluding passage of keys from the small loop at one end thereof; and means on the belt hook for retaining a key keeper including a flat loop extending from one spaced flat leg, a flat loop end bearing resiliently against said one spaced flat leg, and a flat leg extension on the other flat leg in contact with the outer surface of the loop and extending away from the shallow bend beyond the flat loop, whereby said key keeper is retained by said flat loop and said legs are resilient so as to spring apart to separate the flat loop and the leg for the insertion of a belt therebetween.
Claim 3
Dependent Claim 32 words
A key holder in accordance with claim 1 wherein each of the first and second keeper side rods join the small and large half loops substantially at tangent points to both loops.
