Description
TECHNICAL FIELD
[0001] The invention relates to forming holes in doors for
receiving lock sets. More particularly, it relates to the provision
of a simple, easy-to-install, easy-to-use, template for properly
positioning the tools used to make the holes with the door.
BACKGROUND OF THE INVENTION
[0002] It is known to use templates to aid proper positioning of
lock set openings in doors. Known templates in the patent
literature are disclosed by the following U.S. Pat. No. 1,611,930,
granted Dec. 28, 1926, to Murdo C. MacLeod; U.S. Pat. No.
4,415,125, granted Dec. 29, 1987, to Lester R. Livick; U.S. Pat.
No. 4,813,826, granted Mar. 21, 1989, to Raymond R. Riedel; U.S.
Pat. No. 5,114,285, granted May 19, 1992, to Michael K. Brydon;
U.S. Pat. No. 5,807,033, granted Sep. 15, 1998, to Randy E. Benway
and U.S. Pat. No. 6,343,632, granted Feb. 5, 2002, to Varko Vivo
Jinovic.
[0003] A disadvantage of the template disclosed by U.S. Pat. No.
5,114,285 is that the two side plates of the template converge as
they extend away from the edge plate. This enables the side plates
to function as a clamp for clamping the template onto a door. A
disadvantage of this construction is that there is a strong
likelihood that the template will scar the door when it is
installed onto and/or removed off from the door.
[0004] There is a need for a template that is simple in
construction, easy to install and use, and adapted to not scar the
door. The main object of the present invention is to fill this
need.
BRIEF SUMMARY OF THE INVENTION
[0005] The preferred embodiment of the invention comprises an edge
plate that is positionable against an edge of a door, a first side
plate that is positionable against a first side of the door, and a
second side plate that is positionable against the second side of
the door. A plurality of connector pins extend outwardly from the
edges of the edge plate. The side plates have connector pin
receiving openings positioned to receive the connector pins. When
the connector pins are in the connector pin receiving openings, the
side plates of the template can be positioned flat against the
sides of the door and the edge plate can be positioned against the
edge of the door. One or more clamps (e.g. C-clamps) can be used to
clamp the side plates on the door. The connector pins and connector
pin openings will secure the edge plate to the side plates. The
side plates have guide openings in them adapted to receive hole
forming tools and guide them as they drill into the door. The guide
openings are suitably positioned for making lock set mounting
openings at the proper locations in the door for the particular
lock set that is being installed on the door.
[0006] Other objects, advantages and features of the invention will
become apparent from the description of the best mode set forth
below, from the drawings, from the claims and from the principles
that are embodied in the specific structures that are illustrated
and described.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
[0015] FIG. 1 shows an embodiment 10 of the lock set template of
the present invention in a spaced relationship from the lock set
region 12 of a door 14. As best shown by FIG. 3, the template 10
comprises an edge plate 16, a first side plate 18 and a second side
plate 20. The door 14 has a first side 22, a second side 24 and an
edge 26 that extend between the sides 22, 24. The edge 22 is shown
to include a lock plate recess 28, also referred to as a
"mortis".
[0016] Referring to FIG. 3, the side plates 18, 20 may be of
identical construction and may be about six inches wide and nine
and one-quarter inches high, and may be about three-eighths of an
inch thick. The edge surfaces and end surfaces are preferably
substantially square with the side surfaces. Along one edge, the
side plates 18, 20 are formed to include a plurality of connector
pin receiving openings 28. These openings may measure about
one-quarter of an inch in diameter.
[0017] The edge plate 16 is rectangular in shape and has end and
edge surfaces that are substantially square with the side surfaces.
The side surfaces of side plate 18 are substantially parallel. The
side surfaces of side plate 20 are substantially parallel. The side
surfaces of edge plate 16 are substantially parallel. However, a
plug 30 is secured to the inside of edge plate 16, such as by a
pair of screws 32, for example. The screws 32 removably connect the
plug 30 to the edge plate 16. Plug 30 is constructed to snuggly fit
within the lock plate recess 28 for the particular lock set that is
being installed onto the door. Edge plate 16 is provided with a
plurality of connector pins 34, equal in number to the connector
pin openings 28. As will be hereinafter described in more detail,
the connector pins 34 are sized to make a clearance fit with the
openings 28. The spacing of the connector pins 34, in each wall of
connector pins 34 varies and the spacing of the corresponding
connector pin openings 28 varies in the same manner. This allows
each side plate 18, 20 to be connected to the edge plate 16 only
when a particular end of the side plates 18, 20 is directed
upwardly and the opposite end is directed downwardly. Referring to
FIG. 3, the upper two connector pins 34 on each side edge of the
edge plate 16 are spaced apart the same distance as the upper two
connector pin openings 28. The bottom three connector pins 34 on
each edge of the edge plate 16 are spaced apart a distance equal to
the spacing of the bottom three connector pin openings 28. When the
connector pins 34 are in the connector pin openings 28, and the
side plates 18, 20 are connected to the edge plate 16, the gauge
openings 50 in side plate 18 are in alignment with the gauge
openings 36, 38, 40, 42, 44, 46, 48, 50 in the side plate 20.
[0018] The template is installed by setting the plug 30 into the
lock plate recess 28. Either before or after the side plates 18, 20
are connected to the edge plates 16 by use of the connector pins 34
in the connector pin openings 28. For example, the edge plate 16
may be installed by itself, with the plug 30 extending into the
recess 38. Then, side plate 18 may be installed on its side of the
edge plate 16 and side plate 20 may be installed on its side of the
edge plate 16. As shown by FIG. 7, the connector pins 34 makes a
clearance fit with the connector pin openings 28. As a result, the
side plates 18, 20 can be placed flat against the side surfaces 22,
24 of the door 14. If the surfaces are uneven and/or are not
parallel, there will be movement at the connections 28, 32 so that
the side plates 18, 20 remain in tight contact with the door
surfaces of 22, 24 while the connections 28, 34 remain secure. FIG.
4 shows a slight divergence of the side plates 18, 20 with respect
to the edge plate 16. FIG. 5 shows the side plates 18, 20
substantially parallel to each other. FIG. 6 shows a slight
convergence of the side plates 18, 20 relative to the edge plate
16. This construction of the template 10 allows a quick placement
of the edge plate 16 against the edge 26 of the door 14, followed
by a quick placement of the side plates 18, 20 against the sides
22, 24 of the door 14, with the connector pins 34 within the
connector pins 34 within the connector pin openings 28. Then, a
C-clamp can be installed for the purpose of pressing the side
plates 18, 20 against the side surfaces 22, 24 of the door 14. When
the template 10 is secured to the door 14 in this manner, the two
sets of gauge openings 36, 38, 40, 42, 44, 46, 48, 50 are in
alignment with each other. The person who is installing the lock
need only insert the free end of the hole forming tool (e.g. drill
bit) in a selected gauge hole and then use the tool to drill
through the door from the starting gauge hole in one side plate to
the corresponding gauge hole in the opposite side plate. For
example, the workman may put a drill bit in a power drill and
insert the end of the drill in gauge opening 48 in side plate 18
and then drill through the door until the drill bit passes through
the gauge opening 48 in side plate 20. The number of holes that are
drilled, and the sizes of the holes, are determined by the
particular lock set that is being installed on the door 14. After
the holes are formed, the clamp is removed, the side plates 18, 20
are moved away from edge plate 16 and edge plate 16 is moved away
from the door edge 26.
[0019] The template 10 may be provided with a plurality of
different sizes of plug 30, one for each type of lock set that
exists to be installed.
[0020] The illustrated embodiment is only an example of the present
invention and, therefore, is non-limitive. It is to be understood
that many changes in the particular structure, materials and
features of the invention may be made without departing from the
spirit and scope of the invention. Therefore, it is my intention
that my patent rights not be limited by the particular embodiment
that is illustrated and described herein but is to be determined by
the following claims, construed by use of the established rules of
patent claim construction.
