Bohrvorrichtung zum Anschlagen von Scharnierbändern u.dgl.

摘要

A boring device for locating and drilling hinge mounting holes in frame and door members includes a base member with a stop shoulder for positioning the device with respect to the edge of the frame member. A slide member positionally adjustable within a channel in the base member is secured to the base member. The slide member includes at least one bore jig for properly aligning a bit during drilling of one or more mounting holes. Transverse interfitting grooves between the mating surfaces of the base and slide members in conjunction with a screw and slot arrangement in the slide member provide a rigid yet adjustable mounting arrangement between the two elements. Graduated indicia on the base member and a positioning index on the slide member permit the two members to be adjusted with respect to each other for accurate positioning of the bore jig and repositioning of the members.
