Description
DOOR LOCK INSTALLATION KIT
FIELD OF THE INVENTION
This invention relates to door lock installation kits and in particular door lock installation kit that may be used with a variety of door thicknesses and setbacks.
BACKGROUND OF THE INVENTION
Most residential and commercial doors include a door lockset. The vast majority of these are standard door lockset with a predetermined setback from the edge of the door. Common procedure for installing a standard lockset to a door requires the drilling of a 2-1/8" hole through the face of the door and a 1"
hole on the edge of the door perpendicular and in alignment with the 2-1/8" hole.
Installing standard locksets to a door requires two types of information: the thickness of the door and the backset distance of the hole on the face of the door.
There are various devices adapted to aid to drill the holes for a standard lockset on a door that accommodate the thickness and backsets. For example, US
pending patent application # 2004/0240950 covers two ways: an "L-shaped"
bracket and a "U-shaped" bracket in which both are mounted to the edge of the door and can be manipulated to accommodate the backsets. The "U-shaped" bracket consists of a flexible plastic that clamps onto the door edge. Another example of a lockset drilling guide is shown in US pending patent application 2004/0062618 which includes a generally L-shaped bracket with a pair of spacing tabs so that the guide may be used with doors of two different thicknesses. There are number of limitations with this and other guides. Specifically, these guides are not readily adaptable for use with different backsets.
Accordingly, it would be advantageous to provide a door lock installation kit that is easy to use and may be adapted for use with different thicknesses of doors.
Further it would be advantageous to provide a door lock installation kit that may be adapted for use with different backsets.

DETAILED DESCRIPTION OF THE INVENTION
The door lock installation kit of the present invention is used as an aide to correctly cutting the holes for the installation of a door lock. Generally a hole is required for the handle portion that extends through the thickness of the door and another hole that is perpendicular to the handle hole for the latch. The latch hole extends parallel to the plane of the door and intersects the handle hole. The door lock installation kit aids someone to cut the handle hole and the latch hole.
Referring to figure 1, the template of the door lock installation kit of the present invention is shown generally at 20. The template 20 includes a U-shaped bracket 22 and a first and second removable hole saw guides 24.
The U-shaped bracket 22 has a front portion 26 and a first and second side portion 28. The side portions 28 are generally perpendicular to the front portion
-5-26. The front portion has a latch hole 30 generally in the centre thereof. A
pair of screw holes 32 are positioned above and below the latch hole 30. The position of the screw holes 32 generally correspond to the position of the holes on a cover plate for a latch (not shown).
The first and second removable hole saw guides 24 each have a saw hole 34. Each guide 24 is removably attachable to the side portions 28 of the U-shaped bracket 22. The guides 24 are attachable in four possible positions.
Each guide 24 has a finger 36 that extends outwardly from each end thereof and is receivable into a channel 38 (shown in figure 2) in the side portions 28 of U-shaped bracket 22. Each finger 36 has a generally V-shaped groove 40 formed therein on the side of the finger 36 as best seen in figure 2. Groove 40 corresponds to a generally V-shaped elongate ridge 42 on the side of channels 38. The guides 24 are constructed such that when positioned in U-shaped bracket 22 the backset, which is the distance from the inside edge 44 of the U-shaped bracket 22 to the saw hole 34, is a first predetermined distance when the guide 24 is in a first position and is a second predetermined distance when the guide 24 is in a second position. In the first position shown in figure 1, the backset is less than the backset of the second position shown in figure 5. In the first and second positions, the inside surface of the guide 24 is flush with or in the same plane as the inside surface of the side portion 28 as shown in figures 1, 5, 7, 8 and 10. When the guides 24 are in position the saw holes 34 are in alignment and the centre points of the saw holes 34 and the latch hole 30 are in the same plane as shown in figure 3.
pair of screw holes 32 are positioned above and below the latch hole 30. The position of the screw holes 32 generally correspond to the position of the holes on a cover plate for a latch (not shown).
The first and second removable hole saw guides 24 each have a saw hole 34. Each guide 24 is removably attachable to the side portions 28 of the U-shaped bracket 22. The guides 24 are attachable in four possible positions.
Each guide 24 has a finger 36 that extends outwardly from each end thereof and is receivable into a channel 38 (shown in figure 2) in the side portions 28 of U-shaped bracket 22. Each finger 36 has a generally V-shaped groove 40 formed therein on the side of the finger 36 as best seen in figure 2. Groove 40 corresponds to a generally V-shaped elongate ridge 42 on the side of channels 38. The guides 24 are constructed such that when positioned in U-shaped bracket 22 the backset, which is the distance from the inside edge 44 of the U-shaped bracket 22 to the saw hole 34, is a first predetermined distance when the guide 24 is in a first position and is a second predetermined distance when the guide 24 is in a second position. In the first position shown in figure 1, the backset is less than the backset of the second position shown in figure 5. In the first and second positions, the inside surface of the guide 24 is flush with or in the same plane as the inside surface of the side portion 28 as shown in figures 1, 5, 7, 8 and 10. When the guides 24 are in position the saw holes 34 are in alignment and the centre points of the saw holes 34 and the latch hole 30 are in the same plane as shown in figure 3.
-6-In the third and fourth positions, the inside surface of the guides 24 are spaced inwardly from the inside surface of the side portion 28 of U-shaped bracket 22 as shown in figures 3, 6 and 9. A collar 46 is formed around saw hole 34 such that when in the third and fourth positions, the inside surface of guides 24 is spaced inwardly.
The door lock installation kit of the present invention is designed for use with doors having a thickness of 1-3/8 inches or 1- 3/ inches and with a backset of 2-3/8 inches or 2-% inches. Accordingly there are four potential settings, namely a first position of 2-3/8" x 1-3/4"; a second position of 2-3/4" x 1-3/4"; a third position of 2-3/8"
x 1-3/8" and a fourth position of 2-3/4" x 1-3/8". However, it will be appreciated by those skilled in the art that other sets of thicknesses and backsets may also be used.
For the spacings described above the distance between the side portions 28 is inches and the thickness of the collar 46 is 3/16 inch.
In use, the hole saw guides 24 snap into the U-shaped bracket 22 at each end of the side portion 28 of the bracket 22 so that the 2-1/8" saw holes 34 are perpendicular to the 1" latch hole 30 of the bracket 22. The hole saw guides 24 are oriented according to the varying thicknesses (Figures 1 and 3) that doors 48 (shown in figure 7) are available in and backsets (Figures 1 and 5) that the standard locksets are available in. Preferably the hole saw guides 24 are provided with thickness and backset information 51 on the face thereof to aid in the correct orientation of the hole saw guide 24. Once the orientation of the hole saw guides 24 are determined and snapped onto the bracket 22, the template 20 is mounted to the edge of the door 48
The door lock installation kit of the present invention is designed for use with doors having a thickness of 1-3/8 inches or 1- 3/ inches and with a backset of 2-3/8 inches or 2-% inches. Accordingly there are four potential settings, namely a first position of 2-3/8" x 1-3/4"; a second position of 2-3/4" x 1-3/4"; a third position of 2-3/8"
x 1-3/8" and a fourth position of 2-3/4" x 1-3/8". However, it will be appreciated by those skilled in the art that other sets of thicknesses and backsets may also be used.
For the spacings described above the distance between the side portions 28 is inches and the thickness of the collar 46 is 3/16 inch.
In use, the hole saw guides 24 snap into the U-shaped bracket 22 at each end of the side portion 28 of the bracket 22 so that the 2-1/8" saw holes 34 are perpendicular to the 1" latch hole 30 of the bracket 22. The hole saw guides 24 are oriented according to the varying thicknesses (Figures 1 and 3) that doors 48 (shown in figure 7) are available in and backsets (Figures 1 and 5) that the standard locksets are available in. Preferably the hole saw guides 24 are provided with thickness and backset information 51 on the face thereof to aid in the correct orientation of the hole saw guide 24. Once the orientation of the hole saw guides 24 are determined and snapped onto the bracket 22, the template 20 is mounted to the edge of the door 48
-7-where the location of the lockset will be. Since the template 20 has only two pre-determined sizes for thickness, and is made out of a solid plastic with limited flexibility, the user achieves greater stability when it is secured to the edge of the door 48. The screws 50 that are provided with the standard lockset kits are temporarily used to secure the template 20 to the edge of the door 48 (figure 7) for drilling the holes, and ensuring that the backset of the 2-1/8" holes are drilled and positioned accurately.
This door lock installation kit of the present invention can accommodate the two thicknesses of doors: 1-3/8" and 1-3/4", as well as the two backsets of standard locksets: 2-3/8" and 2-3/4". This is easily achieved by matching the indicated sizes of the 2-1/8" hole saw guides on each outside face of the U-shaped bracket shown in FIGS. The 2-1/8" hole saw guides are secure in the U-shaped bracket with a dovetail shape channel 38 (frgure 14) and held in with snaps 52. The 2-1/8"
hole saw guides can easily be snapped out of the U-shaped bracket to accommodate the other thickness and backsets of doors by either flipping or rotating the 2-1/8" hole saw guides and matching the indicated sizes to the U-shaped bracket.
Once the template 20 is configured in its desired orientation, and mounted onto the edge of the door 48, figure 8 displays the method of drilling the holes. Since the template is U-shaped, the intention for the 2-1/8" hole is to drill through half the door from one side and finish drilling through on the other side to avoid the splintering on one side. Specifically, a 2-1/8" hole saw 54 is attached to mandrel 56 and affix to drill (not shown). The pilot drill should extend 1/4" past the teeth of the hole saw 54. The hole saw 54 is lined up with the saw hole 34 in the template 20 and _g_ drilling is begun. To eliminate splintering the user should stop drilling when the pilot drill breaks through the back of the door 48. The hole saw 54 is removed from one side of the door 48 and the hole is completed from the other side of the door 48.
Again, the hole saw 54 is lined up with the saw hole 34 in template 20 using the pilot drill hole previously made and continue drilling until the hole is complete.
The 2 1/8"
hole saw 54 is removed from the mandrel 56 and replaced with the 1" hole saw 58.
Similarly, the pilot drill extends 1/4" past the teeth of the 1" hole saw 58.
The 1" hole saw 58 is lined up with the latch hole 30 in the template 20 on the edge of the door 48.
The latch hole is drilled through to the large face hole. Thereafter the latch plate screws 50 and the template 20 are removed from the door and the lockset is attached to the door 48 as provided in the instructions therewith. Preferably, as shown in figure 16, the door lock installation kit of the present invention is sold including the template 20, a mandrel 56, a hole saw 54 and a latch hole saw 58.
The door lock installation kit of the present invention is described above with a first and second hole saw guide 24. However, it will be appreciated by those skilled in the art that the kit could also work with only one hole saw guide 60. An example of this embodiment is shown in figures 15. This embodiment is similar to that described above however, the collar 62 would have a thickness of 3/8 inch and only one side of the U-shaped bracket 64 would receive a hole saw guide 60. The remainder of the kit would be essentially the same.
Referring to figures 16 and 17, typically the door lock installation kit of the present invention would be sold as shown at 70. The kit 70 includes a template 20 as _g_ well as a mandrel 56, a hole saw 54 and a latch hole saw 58. There would all be packaged together in a sealed package 72.
As used herein, the terms "comprises" and "comprising" are to construed as being inclusive and opened rather than exclusive. Specifically, when used in this specification including the claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or components are included.
The terms are not to be interpreted to exclude the presence of other features, steps or components.
It will be appreciated that the above description related to the invention by way of example only. Many variations on the invention will be obvious to those skilled in the art and such obvious variations are within the scope of the invention as described herein whether or not expressly described.
This door lock installation kit of the present invention can accommodate the two thicknesses of doors: 1-3/8" and 1-3/4", as well as the two backsets of standard locksets: 2-3/8" and 2-3/4". This is easily achieved by matching the indicated sizes of the 2-1/8" hole saw guides on each outside face of the U-shaped bracket shown in FIGS. The 2-1/8" hole saw guides are secure in the U-shaped bracket with a dovetail shape channel 38 (frgure 14) and held in with snaps 52. The 2-1/8"
hole saw guides can easily be snapped out of the U-shaped bracket to accommodate the other thickness and backsets of doors by either flipping or rotating the 2-1/8" hole saw guides and matching the indicated sizes to the U-shaped bracket.

The hole saw 54 is removed from one side of the door 48 and the hole is completed from the other side of the door 48.
Again, the hole saw 54 is lined up with the saw hole 34 in template 20 using the pilot drill hole previously made and continue drilling until the hole is complete.
The 2 1/8"
hole saw 54 is removed from the mandrel 56 and replaced with the 1" hole saw 58.
Similarly, the pilot drill extends 1/4" past the teeth of the 1" hole saw 58.
The 1" hole saw 58 is lined up with the latch hole 30 in the template 20 on the edge of the door 48.
The latch hole is drilled through to the large face hole. Thereafter the latch plate screws 50 and the template 20 are removed from the door and the lockset is attached to the door 48 as provided in the instructions therewith. Preferably, as shown in figure 16, the door lock installation kit of the present invention is sold including the template 20, a mandrel 56, a hole saw 54 and a latch hole saw 58.
