Abstract

Abstract A pliers for handling disks and other flat and thin objects. The pliers are substantially comprised of jaws (4) provided with claws (5), biased against each other by an adjustable tension spring (3), arranged between the arms (1). The jaws (4) are made into a single part, of flexible material, and folded in two portions to form a hinge (6) acting as a penetration limiter, distinct from that (2) of the arms (1). The claws (5) are fixed on the jaws (4) by a turned down edge (10) thicker than the protuberance (12) located at the junction of the arms (1) with the jaws (4). The ends of the claws (5) are tapered and offset so as to facilitate the insertion of the jaws (4) between the object and the handling of the object with the pliers.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 178 words
A pliers for handling flat and thin objects comprising: first and second plier elements each having a handle portion and a substantially flat jaw portion, said first and second plier elements being pivotally joined so that the respective substantially flat jaw portions thereof can mate when in a closed position; and a flexible claw assembly including first and second claws joined together by a hinge, said first and second claws being configured, respectively, to be carried by and to be disposed between said substantially flat jaw portions of said first and second plier elements, said hinge being disposed adjacent to said pivotal joining of said first and second plier elements when said first flexible claw assembly is positioned on said plier elements, said hinge serving as a stop to limit the distance an object can be inserted between said substantially flat jaw portions, said flexible claw assembly being fixed in position on the jaw portions of said first and second plier elements by a turned down edge disposed on the outer face of said first and second claws.
Claim 2
Dependent Claim 178 words
A pliers for handling flat and thin objects comprising: first and second plier elements each having a handle portion and a substantially flat jaw portion, said first and second plier elements being pivotally joined so that the respective substantially flat jaw portions thereof can mate when in a closed position; and a flexible claw assembly including first and second claws joined together by a hinge, said first and second claws being configured, respectively, to be carried by and to be disposed between said substantially flat jaw portions of said first and second plier elements, said hinge being disposed adjacent to said pivotal joining of said first and second plier elements when said first flexible claw assembly is positioned on said plier elements, said hinge serving as a stop to limit the distance an object can be inserted between said substantially flat jaw portions, said flexible claw assembly being fixed in position on the jaw portions of said first and second plier elements by a turned down edge disposed on the outer face of said first and second claws.
