Field of the Invention

[0001] The present invention relates generally to the field of hole routing and drilling templates and guides, and, more particularly, to hole routing and drilling templates and guides for correct positioning of holes for the installation of door handle and lock hardware. Background of the Invention

[0002] Builders, carpenters, homeowners and the like and the like are required to install door handle and lock hardware from time to time on original or new doors.

[0003] One of the hardest tasks of installing door hardware is correctly aligning perpendicular installation and mounting holes.

[0004] Many door hardware sets come with paper or cardboard templates which may be stuck to the door but which are cumbersome and do not eliminate misalignment.

[0005] A need therefore exists for a small and relatively expensive boring and routing template jig for door hardware which can greatly simplify the accurate and rapid installation of door hardware assemblies.

[0006] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country. Summary of the Disclosure

[0026] Figure 1 shows a boring and routing template jig for door hardware installation attached to an edge of a door;

[0027] Figure 2 shows a plan view of a latch edge template plate of the jig in accordance with an embodiment; and

[0028] Figure 3 shows a plan view of a side face template plate of the jig in accordance with an embodiment. Description of Embodiments

[0029] A boring and routing template jig 100 comprises a side face template plate 102, clamps for holding the side face template plate 102 against a side face of a door 103 to be cut, and a latch edge template plate 104 orthogonally connected to an edge 105 of the side face template plate 102 by a connection so that the latch edge template plate 104 can lie across a latch edge of the door 103 to be cut adjacent to the side face.

[0030] The latch edge template plate 104 and the side face template plate 102 comprise respective cutting guide apertures 106. With reference to Figures 2 and 3, the cutting guide apertures 106 may be large and rectangular or circular for routing 07 11 24 with an inverted bearing router, circular drill bit, or the like for the making of installation holes, or relatively smaller and circular for drilling with a drill bit for the making of mounting holes.

[0031] The connection between the edge 105 of the side face template plate 102 and the latch edge template plate 104 maintains a vertical offset (when the door 103 is hung) between the respective guide apertures 106 of the side face template plate 102 and the latch edge template plate 104 but allows horizontal offset adjustment between the latch edge template plate 104 and the side face template plate 102.

[0032] The connection may allow connection of the edge 105 of the side face template plate 102 against a rear surface of the latch edge template plate 104 at various positions across the rear surface.

[0033] In the embodiment shown, the latch edge template plate 104 is rectangular, and the side face template plate 102 is rectangular, and the connection connects a long edge 105 of the side face template plate 102 along a length of the latch edge template plate 104.

[0034] The connection comprises the latch edge template plate 104 having a parallel pair of channels 107 and the edge 105 of the side face template plate 102 having respective fasteners 108 slidably engaging the channels 107. The fasteners 108 can be released to allow horizontal offset adjustment and tightened to maintain horizontal offset between the latch edge template plate 104 and the side face template plate 102.

[0035] In the embodiment shown, the fasteners 108 comprise screws which screw into threaded blind holes 109 in the edge 105 of the side face template plate 102.

[0036] The channels 107 may be countersunk so that the fasteners 108 are recessed and do not protrude above the front surface of the latch edge template plate 104.

[0037] Whereas Figure 3 shows the side face template plate 102 comprising a single pair of blind holes 109 for the fasteners 108, as illustrated in Figure 1, the edge 105 of the side face template plate 102 may comprise a further pair of inner blind holes to accommodate smaller-sized latch edge template plates 104. 07 11 24

[0038] The latch edge template plate 104 may comprise horizontal offset markings 110. The horizontal offset markings 110 may be located at an outer edge of the latch edge template plate 104, as shown in Figure 2, for alignment with at least one of an edge of the door 103 and the side face template plate 102.

[0039] The latch edge template plate 104 may be transparent so that the relative positioning of the door 103 or the side face template plate 102 can be seen through the latch edge template plate 104 with respect to the horizontal offset markings 110.

[0040] As shown in Figures 1 and 2, the horizontal offset markings 110 may be divided into groups to align with either side of the door 103. Specifically, the horizontal offset markings 110 may comprise a central group of markings and a side group of markings. In some embodiments, the latch edge template plate 104 may be flipped to install different door hardware, and the horizontal offset markings 110 may comprise two side groups of markings for alignment irrespective of the orientation of the latch edge template plate 104.

[0041] The clamping may comprise two clamps 111 which engage the side face template plate 102 on either side of the latch edge template plate 104.

[0042] Each clamp 111 may comprise an orthogonal rod 112 which goes into a respective blind hole 113 in the edge 105 of the side face template plate 102.

[0043] Each clamp 111 may comprise an arm 114 connecting the rod 112 to make a C-shape, and the distal end of the arm 114 may comprise a screw 116 therethrough having a movable jaw acting in opposition to the side face template plate 102. Each clamp 111 may comprise an accessible thumbscrew 115 for turning the screw 116.

[0044] The latch edge template plate 104 may comprise two guide apertures 106 for different types of door hardware. As shown in Figure 1, the latch edge template plate 104 may comprise a relatively larger guide aperture 106 for a first type of door hardware and a relatively smaller guide aperture 106 for another type of door hardware.

[0045] These apertures 106 may be located on either side of a longitudinal midline of the latch edge template plate 104 so that the latch edge template plate 104 can be flipped to install either type of respective hardware. 07 11 24

[0046] With reference to Figure 2, the latch edge template plate 104 may comprise longitudinal centreline markings 117 indicating the centreline of respective guide apertures 106.

[0047] As shown in Figure 2, the latch edge template plate 104 may have a horizontal centreline marking 118 vertically centred with respect to a respective guide aperture 106. As such, a centreline may be marked on the door 103 in pencil, after which the jig 100 may be installed so that the horizontal centreline 118 aligns with the marked centreline of the door 103.

[0048] The side face template plate 102 may have a corresponding horizontal centreline marking 119 corresponding in vertical position with the centreline marking 118 of the latch edge template plate 104 when the latch edge template plate 104 is orthogonally connected to the edge 105 of the side face template plate 102 by the connection.

[0049] The side face template plate 102 may also comprise different types of guide apertures 106 for different types of door hardware.

[0050] Whereas different types of latch edge template plates 104 and side face template plates 102 may be interchanged for various types of door hardware installation, the latch edge template plate 104 may have an indication 120 corresponding in vertical position with one of the guide apertures 106 of the side face template plate 102 when the latch edge template plate 104 is orthogonally connected to the edge 105 of the side face template plate 102 to indicate which guide aperture 106 of the side face template plate 102 to use.

[0051] For example, where the guide aperture 106 of the latch edge template plate 104 is for a particular type of mortise lock, the indications 120 may indicate the corresponding guide apertures 106 of the side face template plate 102 for drilling screw holes.

[0052] In the embodiment shown in Figure 1, the jig 100 may comprise an opposing side face template plate 102A having guide apertures 106 corresponding with those of the side face template plate 102. As such, the door 103 may be cut from either side 07 11 24 using either the side face template plate 102 or the opposing side face template plate 102A.

[0053] The opposing side face template plate 102A may be connected to the latch edge template plate 104 using the same connection. Specifically, the opposing side face template plate 102A may have respective fasteners 108 engaging the same channels 107 of the latch edge template plate 104.

[0054] The clamps 111 may bear against the opposing side face template plate 102A to avoid excessive force on the connection.
