Abstract
A drill jig for installing a lockset in a hanging door with an aperture for the lockset. The drill jig has a plate with a plug on one side dimensioned to fit into the aperture. An array of drill bushings is mounted in the plate aligned with a level on the top edge of the plate. Rubber feet protect the the door from being marred by the plate. The plate is positioned against the door in preparation for drilling holes through the drill bushing into the door. A tool is provided having a tee hook which is inserted through the door aperture from a side of the door opposite the drill jig and temporarily secures the drill jig against the door during the drilling operation.
Claims11
A drill jig for installing a doorset into a door panel having a door aperture dimensioned to receive said door set, said door having one side opposite an opposite side, said drill jig comprising:
- a jig plate;
- an array of drill guide holes in said jig plate in a pattern selected to correspond to an array of holes to be drilled in said door through each one of said array of drill guide holes;
- a jig plug mounted on one side of said jig plate for positioning said jig plate against a surface of one side of the door with said jig plug dimensioned to fit snugly inside the door aperture;
- said jig plug having a slotted aperture with an opening on each side of said jig plate;
- a tool having a tee hook and operably constructed to permit placing said tool against said opposite side of said door and inserting said tee hook through said jig plug inserted in the door aperture from the one side of the door.
The drill jig of claim 2 wherein said tool comprises:
- a stem having said teehook mounted on one end;
- a handle secured to another end of said stem;
- a tool plug operably dimensioned to fit in said door aperture and having a tool aperture;
- said stem slidably positioned in said tool aperture;
- said stem, tee hook, handle, and tool plug operably arranged to permit placing said jig plate against said one side of said door with said jig plug inserted in the door aperture, and placing said tool against the opposite side of the door with said tool plug inserted in said door aperture and said stem inserted through said door aperture and slotted aperture and, further, permitting engagement of said tee hook with a far side of said jig plate whereby said jig plate is secured in a position to permit drilling holes in the door through said array of drill guide holes.
A method for installing a lockset in a hanging door having one side and a far side and having a door aperture dimensioned for receiving said lockset which includes the steps in operable order:
- (a) providing a drill jig including:
- (i) a jig plate;
- (ii) a jig plug mounted on one side of said jig plate for positioning said jig plate against a surface of the one side of the door with said jig plug dimensioned to fit snugly inside the door aperture;
- (iii) an array of drill guide holes in said jig plate in a pattern selected to correspond to an array of holes to be drilled in the door through each one of said array of drill guide holes;
- (iv) a bubble level means mounted on said jig plate for guiding a user to orient said jig plate with said jig plug in said door aperture;
- (v) said level oriented with respect to said array to provide that, when said jig plug is in the door aperture and said bubble level is horizontal, a reference line of said array is vertical enabling a user to mount said drill jig on the door with said jig plug inserted in the door aperture, orient said drill jig to where said reference line is vertical and drill holes in the door through each said bushing of said array of bushings;
- (vi) at least three rubber feet means positioned on said one surface of said jig plate for protecting said surface on one side of the door from marring by said drill jig;
- (vii) a tool having a tee hook and arranged for positioning against the opposite side of the door with said tee hook extending through the door aperture and engaging a side of said jig plate opposite said jig plug whereby said jig plate is securable against said one side of the door for drilling an array of holes in the door;
- (b) positioning said jig plate against said door with said plug positioned in said aperture of said door;
- (c) orienting said jig plate to where said bubble level is horizontal;
- (d) temporarily securing said jig plate against said door with said tool;
- (e) drilling holes in said door through said each drill guide hole;
- (f) removing said tool and drill jig and mounting said lockset in said door and bolting said lockset with a bolt in each hole of said array of holes.
