Multitool with wire stripping element
View Patent ↗A tool member for a multitool which is configured to strip wire. The tool member has first and second members which in one form are pivotally attached at a common axis on the handle portion of a multitool where the tool member has an extended orientation and can be retracted into the channel region of the tool member.
1. A multitool configured to strip the insulation of wire from a core portion, the multitool comprising:
a) a pair of opposed jaw members, a first pivot swingably connecting the jaw members for movement relative to each other, each of the jaw members having a working end portion extending from the first pivot in a first direction and a butt portion extending from the first pivot in a second, generally opposite direction,
b) first and second elongated handles each having a channel therein, the jaw members being moveable relative to the handles between an open position in which the jaw member working end portions are exposed and a closed position in which the jaw members are substantially nested in the channels of the handles,
c) a wire stripping tool member having first and second members that are pivotally attached to the first handle and share a common pivot on the first handle where the wire stripping tool member is configured to be in a stored orientation within the channel region and an extended orientation where the wire stripping tool member is extended from channel region, the first and second members each having wire engaging surfaces configured to incise insulation of the wire to remove it from the core portion, the first and second members each have locking surfaces operatively configured to engage a lock bar attached to the handle.
2. The multitool as recited in claim 1 where the wire engaging surfaces are positioned opposite one another where the wire engaging surfaces provide a plurality of slots narrowing in diameter to engage wires of different diameters.
3. The multitool as recited in claim 1 where a stop member prevents the rotation of the first and second stripping members such that the first and second stripping members open with respect to one another at a prescribed angle.
4. The multitool as recited in claim 1 where the locking surfaces engage the lock bar when the wire stripping tool member is in an extended orientation.
5. The multitool as recited in claim 4 where the lock surfaces of the first and second members do not coincide in location when the first and second members are in an open orientation and the lock bar disengages the wire stripping tool member to allow the wire stripping tool member to be repositioned to the stored orientation.
6. A wire stripping device configured to strip the insulation of a wire from the core portion, the wire stripping tool member comprising:
a) a U-shaped handle member,
b) a first member pivotally attached to the U-shaped handle member, the first member having a wire retaining surface configured to hold a wire therein,
c) a second member pivotally attached to the U-shaped handle member and positioned adjacent to the first member, the second member having a wire retaining surface and where a stop member prevents the rotation of the first and second members such that the first and second members open with respect to one another at a prescribed angle,
d) whereas the wire retaining surfaces of the first and second members are configured to coincide in location and share a common pivot on the U-shaped handle member such that when the first and second members are in a closed orientation, the wire retaining surfaces of the first and second members cooperate to cut the insulation of a wire placed therebetween for stripping of the insulation from the core portion of the wire, the wire stripping tool member being configured to fit within U-shaped handle when in a stored orientation.
7. The wire stripping tool member as recited in claim 6 where a lock bar is configured to engage first and second lock surfaces on the first and second members respectively.
8. The wire stripping tool member as recited in claim 7 where the first and second members are orientated to an open orientation the lock surface of the second member allows a prescribed amount of rotation of the second member.
9. The wire stripping tool member as recited in claim 7 whereas when the first and second members are separated when the first and second members are in the open orientation, the first and second lock surfaces engage the lock bar where the width of the second lock surface is greater than the width of the first lock surface so the second member has a prescribed range of rotational motion when the first member is locked to the open orientation.
10. The wire stripping tool member as recited in claim 6 where the U-shaped portion of a handle is a handle of a pocket knife.
