Abstract
Abstract In order to allow conductors or wires having different cross sections to be easily and reliably stripped, the swivelling axis pin of a stripper is designed as a double axis pin whose first substantially cylindrical pivot is arranged in a first leg and whose second substantially cylindrical pivot is arranged in a second leg. Both pivots are held and guided in an intermediate element. This sliding hinge allows both legs with their cutting tool parts to be held as forceps and to be pressed against each other and slid in one direction with respect to each other by actuating guiding elements arranged on the legs.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
122 words
In a device for stripping insulation from wires, said device comprising two legs designed as stripping tools, each leg having at one end at least one swivel pin about which the respective leg can pivot, and having in the area of its other end, at least one cutting tool element; the improvement comprising an intermediate element pivotally connected at spaced points thereof to said swivel pins of said two legs, thereby forming a double hinge, such that when both legs, with their respective cutting tool parts, are held as forceps and are pressed against each other, they slide in contrary motion against each other and their respective cutting tool elements are forced away from each other to strip insulation from a wire.
Claim 2
Dependent Claim
122 words
In a device for stripping insulation from wires, said device comprising two legs designed as stripping tools, each leg having at one end at least one swivel pin about which the respective leg can pivot, and having in the area of its other end, at least one cutting tool element; the improvement comprising an intermediate element pivotally connected at spaced points thereof to said swivel pins of said two legs, thereby forming a double hinge, such that when both legs, with their respective cutting tool parts, are held as forceps and are pressed against each other, they slide in contrary motion against each other and their respective cutting tool elements are forced away from each other to strip insulation from a wire.
Claim 3
Dependent Claim
47 words
The device according to claim 1, further comprising cutting members of an insulation stripping tool for flat wires mounted on facing inner sides of the respective legs, which cutting members are L-shaped with one cutting member being arranged with respect to the other in opposing cutting relationship.
Claim 4
Dependent Claim
39 words
The device according to claim 1, further comprising a hooked extension arranged on one of the legs, and a cutting tool arranged in opposing relationship thereto and guided forwards and backwards with the sliding motion of the two legs.
Claim 5
Dependent Claim
30 words
The device according to claim 1, wherein the double hinge is provided with a return biasing element and a return stop element arranged on at least one of the legs.
Claim 6
Dependent Claim
56 words
The device according to claim 1, wherein the double hinge is designed as a slotted double hinge with the first swivel pin arranged on one of the legs arranged to slide and rotate in a slot in the intermediate element, and with the second swivel pin rotationally held on the other leg and the intermediate element.
Claim 7
Dependent Claim
48 words
The device according to claim 1, wherein the double hinge is designed as a slotted element wherein the two legs are connected by an intermediate element with the first swivel pin arranged on one of the legs and arranged to slide in a groove in the intermediate element.
Claim 8
Dependent Claim
24 words
The device according to claim 6, wherein the groove in the intermediate element consists of two obliquely positioned groove portions with differentially steep slopes.
Claim 9
Dependent Claim
47 words
The device according to claim 1, further comprising a guide element arranged on one of the legs on the side thereof facing the other leg, which guide element is at the same time a stopping element for the conductor to be inserted in the cutting tool elements.
Claim 10
Dependent Claim
28 words
The device according to claim 8, wherein the guide element is designed as at least one peg sliding in at least one longitudinal recess in said one leg.
Claim 11
Dependent Claim
34 words
The device according to claim 8, wherein the guide element is designed as a lever hinge that is rotationally connected with said one leg and us guided in a slot in the other leg.
Claim 12
Dependent Claim
52 words
The device according to claim 1, further comprising a pivot member attached to one leg and a lever, arranged in the pivot member, having a curved surface that comes into forcible contact with a cylindrical roller arranged in a slot in the other leg during the sliding motion of the two legs.
Claim 13
Dependent Claim
47 words
The device according to claim 1, further comprising an essentially v-shaped lever, pivotally held in a slot in one of the legs, said lever engaging forcibly, with an essentially straight portion, a cylindrical pivot rotationally mounted in a socket arranged on the other one of the legs.
Claim 14
Dependent Claim
31 words
The device according to claim 1, wherein the intermediate element is arranged at an angle of between 30° and 90° with respect to the longitudinal direction of one of the legs.
Claim 15
Dependent Claim
50 words
The device according to claim 1, further comprising a return stop element designed as a cylindrical pivot running in a recessed slot in one of the legs, and an arm holding said return stop element and arranged in the vicinity of one of the pivot points of the swivel pins.
Claim 16
Dependent Claim
33 words
The device according to claim 1, further comprising a blade element arranged on a piston bolt that is connected to an arm and is guided by a swivel pin in the piston bolt.
Claim 17
Dependent Claim
34 words
The device according to claim 1, further comprising a raised grip disposed on the outer side of at least one of the legs to facilitate movement of the legs with respect to each other.
Claim 18
Dependent Claim
22 words
The device according to claim 6, wherein the intermediate element is held rotationally by the second swivel pin on the other leg.
Claim 19
Dependent Claim
16 words
The device according to claim 6, wherein the intermediate element is fixed on the other leg.
