Description

Technical Field

[0001] The present invention relates generally to the field of hole milling and drilling templates and guides, and more specifically, to hole milling and drilling templates and guides for properly positioning holes for installing door handles and lock hardware. Background Technology

[0002] Builders, carpenters, homeowners, and others need to install door handles and lock hardware on original or new doors from time to time.

[0003] One of the most difficult tasks in installing door hardware is correctly aligning the vertical mounting holes and assembly holes.

[0004] Many door hardware kits come with paper or cardboard templates that can be glued to the door, but this is not only cumbersome but also fails to eliminate misalignment.

[0005] Therefore, there is a need for a small and relatively expensive drilling and milling template jig for door hardware that can greatly simplify the accurate and rapid installation of door hardware components.

[0006] It should be understood that if any prior art information is mentioned herein, such mention does not constitute an admission that such information is part of common general knowledge in the field in Australia or any other country. Summary of the Invention

[0007] This document provides a drilling and milling template fixture for door hardware installation, comprising a side template strip defining at least one side cutting guide hole; a clamping device configured to secure the side template strip to the side of a door in use; and a latching edge template strip defining at least one cutting guide hole and a pair of channels orthogonally engaging a pair of fasteners projecting from the edge of the side template strip. The front template strip is orthogonally connected across the edge of the side template strip by the fasteners, wherein when the side template strip is secured to the side of the door in use, the fasteners maintain a vertical offset between the side template strip and the front template strip, and allow the front template strip to be horizontally offset relative to the side template strip.

[0008] In addition, the side template strip can be rectangular, and the edge of the side template strip from which a pair of fasteners protrude can be a long edge.

[0009] Furthermore, the template strip can be rectangular.

[0010] This allows the fastener to be recessed into the channel.

[0011] Fasteners can be engaged into corresponding blind holes in the edge of the side template strip.

[0012] The clamping device may include a pair of clamping members, with the side template strip located between the pair of clamping members, and the clamping device defines an orthogonal bar that can engage with a corresponding blind hole in the edge of the side template strip.

[0013] Furthermore, the clamping device may have an arm connecting a screw, the screw having movable jaws that act opposite to the side template pressure strip.

[0014] The face template strip can be transparent and has a horizontal offset mark, allowing for visual measurement of the relative position of the side template strip with respect to the horizontal offset mark.

[0015] Furthermore, the face template strip can have a horizontal offset mark.

[0016] The horizontal offset markers consist of a set of center markers and a set of side markers.

[0017] At least one cutting guide hole of the face template strip may include two cutting guide holes for two types of door hardware.

[0018] The two cutting guide holes can be located on either side of the centerline of the face template strip, and the fastener allows the face template strip to rotate in either of two directions spaced 180° apart, thereby using either of the two cutting guide holes.

[0019] The face template strip may have a centerline mark centered relative to its cutting guide hole.

[0020] The side template strip can have a centerline mark that corresponds to the centerline mark of the front template strip.

[0021] At least one cutting guide hole of the side template strip may have two cutting guide holes for two types of door hardware.

[0022] The face template strip may have an indicator corresponding to one of the cutting guide holes in the side template strip.

[0023] The fixture may also include opposing side template strips, wherein the side template strips are further orthogonally connected to the edges of the opposing side template strips by corresponding fasteners located at the edges of the opposing side template strips.

[0024] Other aspects of the invention are also disclosed. Attached Figure Description

[0025] Although any other forms may fall within the scope of this invention, preferred embodiments of this disclosure will now be described by way of example only and with reference to the accompanying drawings, wherein:

[0026] Figure 1 The image shows a drilling and milling template fixture attached to the edge of a door for door hardware installation;

[0027] Figure 2 A plan view of the face template strip of the fixture according to one embodiment is shown; and

[0028] Figure 3 A plan view of the side template strip of a fixture according to one embodiment is shown. Detailed Implementation

[0029] The drilling and milling template fixture 100 includes a side template strip 102, a clamping device for fixing the side template strip 102 against the side area of ​​the door 103 to be cut, and a face template strip 104 orthogonally connected to the edge 105 of the side template strip 102 by a connector, such that the face template strip 104 can cross the edge face area of ​​the door 103 to be cut adjacent to the side area.

[0030] The face template strip 104 and the side template strip 102 include corresponding cutting guide holes 106. (Reference) Figure 2 and Figure 3 The guide hole 106 can be large and rectangular or circular for milling with an inverted bearing milling cutter, a circular drill bit, etc. to make a mounting hole, or it can be relatively small and circular for drilling with a drill bit to make an assembly hole.

[0031] The connector between the edge 105 of the side template strip 102 and the front template strip 104 maintains the vertical offset between the corresponding guide holes 106 of the side template strip 102 and the front template strip 104 (when the door 103 is hung), but allows for horizontal offset adjustment between the front template strip 104 and the side template strip 102.

[0032] The connector allows the edge 105 of the side template strip 102 to connect to and abut against the rear surface of the front template strip 104 at various locations throughout the rear surface.

[0033] In the illustrated embodiment, the face template strip 104 is rectangular and the side template strip 102 is rectangular, and the connector connects the long edge 105 of the side template strip 102 along the length of the face template strip 104.

[0034] The connector includes a face template strip 104 having a pair of parallel channels 107, and an edge 105 of a side template strip 102 having a corresponding fastener 108 that slides into the channels 107. The fastener 108 can be loosened to allow for horizontal offset adjustment and can be tightened to maintain the horizontal offset between the face template strip 104 and the side template strip 102.

[0035] In the illustrated embodiment, the fastener 108 includes a screw that is screwed into a threaded blind hole 109 in the edge 105 of the side template strip 102.

[0036] Channel 107 may be a countersunk hole, so that fastener 108 is recessed so as not to protrude above the front surface of faceplate strip 104.

[0037] although Figure 3 The side template strip 102 is shown to include a single pair of blind holes 109 for fasteners 108, as shown. Figure 1 As shown, however, the edge 105 of the side template strip may include an additional pair of internal blind holes to accommodate a smaller face template strip 104.

[0038] The face template strip 104 may include a horizontal offset mark 110. For example... Figure 2 As shown, the horizontal offset mark 110 may be located at the outer edge of the face template strip 104 for alignment with at least one of the edge of the door 103 and the side template strip 102.

[0039] The face template strip 104 can be transparent, so that the relative positioning of the door or side template strip 102 relative to the horizontal offset mark 110 can be seen through the face template strip 104.

[0040] like Figure 1 and Figure 2 As shown, the horizontal offset marks 110 can be divided into multiple groups aligned with either side of the door 103. Specifically, the horizontal offset marks 110 may include a set of center marks and a set of side marks. In some embodiments, the faceplate strip 104 is flip-up to install different door hardware, and wherein the horizontal offset marks 110 include two sets of side marks for alignment, regardless of the orientation of the faceplate strip 104.

[0041] The clamping device may include two clamping members 111, which engage the side template strip 102 on either side of the face template strip 104.

[0042] Each clamp 111 may include an orthogonal bar 112 that enters a corresponding blind hole 113 in the edge 105 of the side template strip 102.

[0043] Each clamping member 111 may include an orthogonal bar 112 to form a C-shaped arm 114, wherein the distal end of the arm 114 may include a screw 116 passing through it, the screw having movable jaws that act opposite to the side template pressure strip 102. Each clamping member 111 may include an accessible wing screw 115 for rotating the screw 116.

[0044] The faceplate strip 104 may include two guide holes 106 for different types of door hardware. For example... Figure 1 As shown, the faceplate strip 104 may include a relatively large guide hole 106 for the first type of door hardware and a relatively small guide hole 106 for different types of door hardware.

[0045] These holes 106 can be located on either side of the longitudinal centerline of the faceplate strip 104, allowing the faceplate strip 104 to be flipped to install any type of corresponding hardware.

[0046] refer to Figure 2 The face template strip 104 may include a longitudinal centerline mark 117 that indicates the centerline of the corresponding guide hole 106.

[0047] For example Figure 2 As shown, the face template strip 104 may have a horizontal centerline mark 118 that is vertically centered relative to the corresponding guide hole 106. Therefore, the centerline can be marked on the door 103 with a pencil, and then the clamp 100 can be installed such that the horizontal centerline 118 is aligned with the marked centerline of the door 103.

[0048] When the face template strip 104 is orthogonally connected to the edge 105 of the side template strip 102 via a connector, the side template strip 102 may have a corresponding horizontal centerline mark 119 at a vertical position that corresponds to the centerline mark 118 of the face template strip 104.

[0049] The side template strip 102 may also include different types of guide holes 106 for different types of door hardware.

[0050] Although different types of face template strips 104 and template strips 102 are interchangeable for various types of door hardware installations, when the face template strip 104 is orthogonally connected to the edge 105 of the side template strip 102, the face template strip 104 may have an indicator 120 in a vertical position corresponding to one of the guide holes 106 of the side template strip 102 to indicate which guide holes 106 of the side template strip 102 are used.

[0051] For example, when the guide hole 106 of the face template strip 104 is used for a specific type of latch lock, the indicator 120 can indicate the corresponding guide hole 106 of the side template strip 102 for which a screw hole is drilled.

[0052] exist Figure 1 In the embodiment shown, the clamp 100 may include opposing side template strips 102A, which have guide holes 106 corresponding to the guide holes of the side template strips 102. Therefore, the door 103 can be cut from either side using either the side template strips 102 or the opposing side template strips 102A.

[0053] The same connectors can be used to connect opposing side template strips 102A to face template strips 104. Specifically, another side template strip 102A may have corresponding fasteners 108 that engage with the same channels 107 of the face template strip 104.

[0054] The clamping member 111 can abut against the opposing side template strip 102A to avoid applying excessive force to the connector.
