Abstract

The present invention is structured so that a guide pin will be captured within holes disposed on opposite walls of a case. A stopper wedge piece having a contact surface rides on the guide pin at one end of the case while a spring is disposed on the guide pin at the other end of the case. The guide pin has a collar close to one end that prevents the spring from slipping off that end of the guide pin. The collar also prevents the guide pin from passing through the hole at that end of the case. The spring keeps the stopper wedge pressed toward one side of the case while at the same time keeps the guide pin collar pressed toward the other side of the case. A metal plate pressed into the bottom of the case prevents wear of the case as the stopper wedge rides against the bottom plate during use. Assembly is facilitated by a downward incline toward the outside is formed on the lower portion of the hole on the case wall into which the stopper end of the guide pin is inserted. The steps of assembly include first pressing the bottom liner plate into the case. Second, slide the spring onto the stopper end of the guide pin until it contacts the collar. Third, slide the stopper wedge onto the guide pin, compressing the spring. Fourth, insert the stopper end of the guide pin through the hole at the stopper end of the case beyond its final position, taking advantage of the outward bevel to insert the guide pin at an incline. Finally, swing the collar end of the guide pin into alignment with the opposite hole, and allow the spring to urge the end of the guide pin into the hole until the collar contacts the wall of the case.

Claims

1. A vibration-preventing device for an opening/closing body in an vehicle comprising:

a guide pin spanning a case, said guide pin passing through a stopper wedge and a spring in said case;

a stopper end and a collar end of said guide pin captured in said case in two holes disposed on opposite side walls of said case;

said stopper wedge and said spring contacting said collar end of said guide pin;

said spring urging said guide pin toward a collar side wall of said case;

an incline formed downward and outward on a lower portion of said hole in a stopper side wall of said case through which a stopper end of said guide pin is inserted; and

a contact surface is formed toward a collar end of said guide pin contacting said collar side wall of said case.

2. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 1 further comprising:

a plate disposed on a bottom surface of said case;

said plate having a length greater than a length of said bottom surface of said case; and

said plate is attached by pressing said plate into said case.

3. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 2 wherein ends of said plate are sawtooth shaped.

4. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 3 wherein a drainage hole is disposed at least one corner of said bottom surface of said case.

5. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 3 wherein a corner on at least one end of said plate is bevelled.

6. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 5 wherein a drainage hole is disposed at least one corner of said bottom surface of said case.

7. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 2 wherein a corner on at least one end of said plate is bevelled.

8. A vibration-preventing device for an opening/closing body in an vehicle as described in claim 7 wherein a drainage hole is disposed at least one corner of said bottom surface of said case.

9. A vibration-preventing device comprising:

a guide pin having a collar, a stopper end, and a collar end;

said stopper end disposed in a stopper hole;

said collar end disposed in a collar contact hole;

said collar substantially larger than said collar contact hole;

a stopper end-wall, and a collar end-wall;

said stopper hole disposed in said stopper end-wall;

said collar contact hole disposed in said collar end-wall;

said guide pin spanning a distance between said stopper hole and said collar contact hole;

a stopper wedge slidably disposed on said guide pin; and

a spring disposed on said guide pin between said stopper wedge and said collar, said spring simultaneously urging said stopper wedge toward said stopper hole and said collar toward said collar contact hole.

10. The vibration-preventing device of claim 9, further comprising

a case having said stopper end-wall, and said collar end-wall.

11. The vibration-preventing device of claim 9 further wherein said wear resistant bottom is a metal plate press-fit into said case.

12. A vibration-preventing device, comprising:

a stopper body having a wedgable shape, a leading end, and a following end;

at least one guide pin, said at least one guide pin having an axis, a collar, a stopper end, and a collar end;

a collar contact hole disposed in a collar end-wall;

said collar end of said at least one guide pin disposed in said collar contact hole;

said stopper body slidable along a path defined by said axis of said at least one guide pin, said path having an end, said end defining a position beyond which said stopper body cannot slide;

at least one spring having a stopper contact end and a collar contact end;

said stopper contact end of said spring contacting said following end of said stopper body; and

said spring biased to urge said guide pin into said collar contact hole while simultaneously urging said stopper body to move along said path in a direction lead by said leading end of said stopper wedge.
