Abstract

A door jig assembly for a vehicle, the vehicle having a door and an inner door jamb forming a part of a vehicle door frame. An arcuate bracket portion is fixedly secured to the inner door jamb. A coil spring member surrounds an intermediate extending location of the bracket portion, a first tab end of the coil spring biasingly engaging a location along the bracket portion and a second extending stem and passing through an aperture defined in the vehicle door. A collar secures to a further location of the bracket portion and exhibits a cam surface in abutting contact with an arcuate extending surface of the coil spring member. The coil spring member influences the door to remain in a first closed position, subsequent rotation of the door causing the spring to rotate about the cam surface to influence the door in an opposite and door open position.

Claims

1. A door jig assembly for use with a vehicle, the vehicle including a door having an inner facing edge, through which is defined at least one aperture, and opposing an inner door jamb forming a part of a vehicle door frame, the door further capable of being pivoted about hinges secured to the door frame and between opened and closed positions, said jig assembly comprising:

an arcuate bracket portion fixedly secured to the inner door jamb;

a coil spring member surrounding an intermediate extending location of said bracket portion, a first tab end of said coil spring biasingly engaging a location along said bracket portion, a second end of said coil spring defining an elongate extending stem portion passing through the aperture defined in the vehicle door; and

a collar secured to a further location of said bracket portion and exhibiting a cam surface in abutting contact with an arcuate extending surface of said coil spring member;

said coil spring member influencing the door to remain in a first closed position, rotation of the door to a second open position causing said coil spring to rotate about said cam surface of said collar and to influence said door in an opposite and door open position.

2. The door jig assembly as described in claim 1, said arcuate bracket portion further comprising first and second legs extending from opposite ends of said intermediate bracket portion, said legs engaging first and second locations associated with the inner door jamb.

3. The door jig assembly as described in claim 2, said first leg further comprising a lower leg terminating in a substantially “

U”

shaped and perpendicularly extending portion, said “

U”

shaped portion aligning with an aperture in the door jamb and through which is engaged a mounting bolt for securing said first leg thereto.

4. The door jig assembly as described in claim 3, said bolt further comprising an axially spaced collar and defining an annular recess therebetween for seating said “

U”

shaped bracket portion and for spacing said bracket portion from the inner door jamb.

5. The door jig assembly as described in claim 3, said second leg further comprising an upper leg extending through a further spaced apart aperture defined in the door jamb.

6. The door jig assembly as described in claim 5, said collar securing to an upper end of said intermediate extending location of said bracket portion and being rotatably restrained by said upper extending leg.

7. The door jig assembly as described in claim 1, said cam surface associated with said collar further comprising a first circumferentially extending and tapered location corresponding with said first closed position, a succeeding second and cam lobe location corresponding with said second open position.

8. The door jig assembly as described in claim 7, said closing and opening influence positions corresponding to a substantially 90°

rotation of the door relative to the inner doorjamb.

9. The door jig assembly as described in claim 1, further comprising said coil spring extending stem portion biasing against an inside surface of the vehicle door and exhibiting a cantilever load in said first and second positions.

10. The door jig assembly as described in claim 1, said coil spring member exhibiting a specified shape and size and being constructed from a spring steel material.

11. The door jig assembly as described in claim 1, further comprising a sleeve inserted between said intermediate extending location of said bracket and said coil spring, said sleeve maintaining axial alignment between said sleeve and said coil spring during rotation of the door.

12. A door jig assembly for use with a vehicle, the vehicle including a door having an inner facing edge, through which is defined at least one aperture, and opposing an inner door jamb forming a part of a vehicle door frame, the door further capable of being pivoted about hinges secured to the door frame and between opened and closed positions, said jig assembly comprising:

an arcuate bracket portion fixedly secured to the inner door jamb, said arcuate bracket portion further comprising first and second legs extending from an intermediate extending location thereof;

a coil spring member surrounding said intermediate extending location of said bracket portion, a first tab end of said coil spring biasingly engaging a location along said bracket portion, a second end of said coil spring defining an elongate extending stem portion passing through the aperture defined in the vehicle door; and

a collar secured to a further location of said bracket portion and exhibiting a cam surface in abutting contact with an arcuate extending surface of said coil spring member, said cam surface further defining a first circumferentially extending and tapered location corresponding with a first door closed position, a succeeding second and cam lobe location corresponding with a second door open position;

said coil spring member seating within the extending and tapered location to influence the door to remain in said first closed position, rotation of the door to a second open position causing said arcuate extending surface of said coil spring to rotate about said cam surface of said collar, into said cam lobe location, to thereby influence said door in an opposite and door open position.

13. A door jig assembly for use with a vehicle, the vehicle including a door having an inner facing edge, through which is defined at least one aperture, and opposing an inner door jamb forming a part of a vehicle door frame, the door further capable of being pivoted about hinges secured to the door frame and between opened and closed positions, said jig assembly comprising:

an arcuate bracket portion fixedly secured to the inner door jamb;

a coil spring member surrounding an intermediate extending location of said bracket portion, a first tab end of said coil spring biasingly engaging a location along said bracket portion, a second end of said coil spring defining an elongate extending stem portion passing through the aperture defined in the vehicle door; and

a cam surface established between an arcuate extending surface of said coil spring member and an abutting surface associated with said bracket portion;

said coil spring member influencing the door to remain in a first closed position, rotation of the door to a second open position causing said coil spring to rotate about said cam surface of said collar and to influence said door in an opposite and door open position.
