Abstract

A jig is provided which is capable of being selective locked in place to support a work piece and quickly dropped out of place to allow the work in progress to pass by. The jig includes a plurality of fingers which can be selectively configured to support a variety of work pieces. The fingers can be easily reconfigured to handle a variety of work pieces without requiring modification of the basic jig structure.

Claims

1. A jig for supporting a plurality of wires for bundling and taping, the jig comprising:

a head having a base and at least one removable tine, said base having a plurality of channels formed therein adapted to receive said at least one tine and said at least one tine adapted to be received in at least one of said channels and to extend from said base to form a support member by which said plurality of wires are supported for bundling, said tine having a locating means and each of said channels having at least one receptacle for receiving the locating means of said tine whereby said tine rests in at least one of said channels and said locating means is received in one of said at least one receptacle;

a retainer for retaining said at least one tine on the base of said head;

a shaft having a first end upon which said head is removably secured; and

a mounting member adapted for mounting said shaft to a work surface, said mounting member further adapted to selectively secure said shaft in a first position and further adapted to selectively release said shaft from said first position to a second position.

2. A jig as set forth in claim 1 wherein said mounting member comprises a mounting base having a shaft passageway formed therethrough through which said shaft slides, said mounting base further having a locking cam pivotally secured therein, and wherein said shaft has a second end to which is affixed a follower and wherein said shaft further has a cam engaging means located between said first and second ends, said locking cam and said follower selectively coacting to alternately engage said cam on said cam engaging means to secure said shaft in said first position and to disengage said cam from said cam engaging means to release said shaft from said first position to said second position.

3. A jig as set forth in claim 1 wherein said retainer is removably secured to the base of said head whereby said tine when secured is received within one of said channels and is sandwiched between the base of said head and said tine retaining means with said locating means received in one of said at least one receptacle of said channel.

4. A jig for assembling a wire harness, said wire harness formed of a plurality of wires which are bundled into groups for routing within a vehicle, said jig comprising:

a head having a base and a plurality of removably securable tines, said base having a plurality of channels formed therein for receiving said tines, said tines extending outward from said base to form a support fork for selectively separating said wires for bundling and for supporting said wires while said wires are being bundled, each of said tines having a locator protrusion thereon and each of said channels having at least one locator dimple, each of said locator protrusions adapted to seat in a respective one of said locator dimples to establish the position of each of said tines with respect to said base;

a shaft having a first end upon which said head is removably secured; and

a collar adapted to mount said shaft to a work surface, said collar having a passageway through which said shaft travels between a secured position above said work surface and a relaxed position.

5. A jig as set forth in claim 4 further comprising a tine securing plate for securing said tines to said base, said tine securing plate being removably secured to said base, whereby said tines are received within said channels and are sandwiched between said base and said tine securing plate with each of said locator protrusions seated in a respective one of said locator dimples when said tines are secured to said base by said tine securing plate.

6. A jig as set forth in claim 5 wherein said collar includes a cam pivotally secured therein near said passageway, and wherein said shaft has a second end, opposite said first end, upon which is located a cam follower, and wherein said shaft further has, located between said first and second ends, a cam shoulder, wherein said shaft is held in said secured position when said cam is engaged on said cam shoulder, and wherein said shaft rests at said relaxed position otherwise, wherein said cam follower contacts and rotates said cam when said shaft is pulled upward away from said work surface, wherein a first alternate pulling of said shaft and contacting of said follower with said cam rotates said cam to a first position to engage said cam shoulder and wherein a second alternate pulling of said shaft and contacting of said follower with said cam rotates said cam to a second position to disengage from said cam shoulder and allow said cam shoulder to pass by said cam unimpeded.
