Abstract
A hand tool for assembling two or more articles along an extended plane. Arcuate motion of a movable handle is converted to axial movement of a presser plate to assemble the articles placed on an aligned platen. The movable handle controls a drive bar which is coupled to the tool frame by pivotally movable links which move the drive bar in two orthogonal directions and to the presser plate to move it in two orthogonal directions by means of pivotally movable links coupled to the drive bar. The movements along one orthogonal axis cancel one another and the movements along the other orthogonal axis are cumulative whereby the presser plate is moved only in the direction of the platen.
Claims16
A hand tool for joining two or more objects together comprising:
- a frame member having a first end portion, a second end portion and an intermediate portion therebetween;
- a movable support member having first and second ends, said first end pivotally coupled to said intermediate portion of said frame member to permit movement of said support member second end with respect to said frame member second end portion;
- a latch bar pivotally coupled to said second end of said support member and releasably coupled to said frame member second end portion to prevent relative movement of said support member with respect to said frame member;
- handle means having first and second ends, said second end of said handle means pivotally coupled to said intermediate portion of said frame member;
- presser plate means;
- first coupling means coupled to said presser plate means and said frame member between said intermediate portion and said second end portion;
- and second coupling means coupling said presser plate to said second end of said handle means;
- the arcuate movement of said first end of said handle means towards said first end portion of said frame member driving said presser plate axially towards said support member.

- a support member having first and second ends, said first end coupled to said intermediate portion and said second end coupled to said second end portion;
- handle means having first and second ends, said second end of said handle means pivotally coupled to said intermediate portion of said frame member;
- presser plate means;
- first coupling means coupled to said presser plate means and said frame member between said intermediate portion and said second end portion;
- said first coupling means comprising a drive bar;
- first links having first and second ends, said first ends of each of said first links pivotally mounted to said frame member and said second ends of each of said first links pivotally mounted to said drive bar;
- second links each having a third and a fourth end, said third ends of each of said second links pivotally mounted to said drive bar and each of said fourth ends of said second links pivotally mounted to said presser plate;
- and second coupling means coupling said presser plate to said second end of said handle means;
- said second coupling means comprising a pivotal connection between said second end of said handle means and said presser plate and a pivotal connection between said second end of said handle means and said drive bar;
- the arcuate movement of said first end of said handle means towards said first end portion of said frame member driving said presser plate axially towards said support member.
