Description
FIELD OF THE INVENTION
The present invention is related to commercial or residential electrical wiring and component installation, and pertains more particularly to a template system for locating and cutting gang openings for installing stud-mounted “old work” electrical gang boxes. The invention is further directed to a template system for easily locating and cutting other openings of various sizes in a wall, ceiling or other surface.
BACKGROUND OF THE INVENTION
Wiring and other components for electrical, networking or other such systems in a residential or commercial structure is installed utilizing either “new work” or “old work” installation techniques. The term “new work”, such as when used with reference to installing wiring and components in new home construction, refers to installation of the wiring and components wherein the wiring and components are routed through and installed within the framing of the structure prior to installation of the drywall wall/ceiling covering. The term “old work” refers to the installation of additional wiring or components to existing wiring or components, or to existing wiring or components in an existing structure. A common “old work” example is the installation of an electrical gang box for a new electrical outlet along an existing wiring branch.
It is commonly required that in “old work” installation and repair, at least a portion of the wall covering, typically being drywall, be removed to allow access to, or installation of the wiring or components. Particularly, for installation of electrical gang boxes for installing a new electrical outlet, a rectangular-shaped opening is generally required to be cut from the drywall, and the opening must be level both horizontally and perpendicularly to a horizontal line. It is also desired in such “old work” gang box installation that the location of the new opening is in the desired position relative to a floor, wall or ceiling in the room were the new outlet is installed.
Typical “old work” gang box installation involves locating, scribing and cutting the opening from the existing drywall covering, and installing an “old work” gang box which attaches directly to the drywall, typically utilizing a screw-mounted tab which is rotated to secure behind drywall and a screw accessible from the front of the gang box. A variety of other such means for securing a gang box to drywall have been introduced in the art as well.
The majority of “new work” gang boxes installed in the framing of the structure, for instance, in new home construction, are firmly secured to a framing member of the structure, usually a vertical wall stud, prior to the installation of drywall. It is well-known in the art that, for obvious reasons of stability, rigidity and safety, it is preferable that the gang box be mounted to a stud or other secure member in the framing of the wall boxes, hence such installation in new home construction. In such an application the gang box, and thereby the electrical outlet secured to the gang box, is less prone to jarring or damage caused by contact between cord ends plugged into the outlet and other objects, such as furniture for example, or drywall damage due to over-tightening of the mounting screws. Stability is further compromised in a drywall-mounted gang box application when the drywall, for whenever reason be it moisture damage, or deterioration over time, becomes softer and less able to support and secure the gang box. A particular advantage in such stud-mount application is thereby gained over “old work” drywall-mounted gang boxes, which are typically made of plastic or other non-metal material, and are much more prone to damage compared to metal stud-mounted gang boxes.
For “old work” installation of a new outlet it is therefore preferable that the new outlet be located such that the gang box to which the new outlet is attached is securely fastened to a stud or other framing member within a wall or ceiling. The opening for the new outlet must therefore be not only square, level and located a specific distance from the floor or wall, but must also be located such that one vertical side of the opening is exactly aligned with, and adjacent to, a side surface of a vertical framing stud, for instance, for the purpose of mounting the gang box to the side of the vertical stud. If such a gang box opening is not perfectly located and aligned, upon securing the gang box to the stud, damage to the drywall may occur due to misalignment between the gang box and the opening, and may also adversely affect the alignment and attachment of the wall plate covering the outlet. Presently, such “old work” installation of stud-mounted electrical gang boxes is therefore most often, and best carried out by, those trained in the skill of the art.
Various “old work” methods and apparatus have been developed for locating, scribing and cutting openings in drywall for installation of stud-mounted gang boxes, utilizing such as electronic stud finders, contractor's levels equipped with bubble levelers, and hand-held templates for marking or scribing the wall with an outline of the desired opening. Many “old work” gang boxes are supplied with paper templates for marking the opening prior to cutting.
Much improvement, however, is still needed in the art to enable one with ordinary skill to accurately locate and cut an opening in drywall for a stud-mounted gang box installation. Present techniques require many separate steps and devices to accurately scribe and cut such an opening. The person of ordinary skill performing the installation must first locate the stud behind the drywall using such as an electronic stud finder, manually mark on the drywall the location of the edge of a vertical stud, and then utilize several other devices and means for locating, scribing and cutting the gang box opening such that it is square and level and closely aligned with the vertical framing stud to which it will be mounted.
Such methods for locating and scribing the opening, utilizing an electronic stud finder and carpenter's level or hand-held template, for instance, easily lend themselves to errors in scribing or cutting the opening, because of the manual nature of the actions. Great care must be taken to accurately mark perfectly level horizontal and vertical lines for the new opening. When utilizing a hand-held paper gang box opening template, accurate marking around the periphery of the paper template is often difficult and prone to error, and hand-held leveling templates utilizing such as spiral cutting tools, or roto-zip tools as they are often referred to as, are often difficult to manually hold stationary to drywall while cutting the opening with the cutting tool around the periphery of the template. When utilizing a hand-held drywall saw for cutting a scribed opening, great care must also be taken to avoid cutting into electrical or other wires or cables which may be located behind the cutting line, and unknown to the person performing the cut.
An inherent functional limitation in hand-held gang box opening templates is that the templates are typically available in sizes applicable to either a single-gang box opening, or a dual-gang opening, or in some instances, both. Such a hand-held template provides no advantage, however, to one wishing to easily cut a square and level opening of a size different from what is required for a standard single or dual gang box, such as for a junction box for wiring of a local area network (LAN), for instance. Slight variances in the dimensions of “old work” gang boxes may require openings having dimensions slightly different from standard, posing further problems to the user of a conventional hand-held gang box opening template.
What is clearly needed is an “old work” template system for accurately locating and cutting an opening in drywall or other such wall covering, wherein the user of average skill may accurately locate the position of the cut relative to a framing member within a wall, for example, and precisely cut a square and level opening of predetermined size from the drywall, the opening oriented such that it is properly positioned relative to the edge of the wall stud or framing member for subsequent mounting of a desired box. Such a template system should accurately pinpoint the location of the gang box mounting surface of a stud or framing member behind drywall, indicating to the user such alignment, enabling the user to then secure the template in the exact level position relative to the edge of the stud or framing member, and to accurately cut the desired opening along an outline of a predetermined size provided by the template. By utilizing such a template system in preferred and alternative embodiments the user is enabled to adjust the template horizontally and vertically so as to accurately cut square and level openings of various predetermined sizes, accurately positioned relative to a framing stud, floor, wall or ceiling, for example, or to accurately cut square and level openings in drywall, the openings having dimensions much larger, and of different shapes than are required for gang box installation. The template system of the present invention enables the user of average skill to repeatedly perform such precision cuts eliminating the need for several separate steps and devices for locating, measuring, scribing and cutting the opening, such as is required in conventional art. The system should also be inexpensive to manufacture utilizing many conventionally known methods and apparatus for leveling, stud location, distance measurement, opening measurement, and so on, and also be lightweight and easily handled, positioned or otherwise manipulated by a single user, allowing the user to easily reposition the template system in various orientations or positions for repeated cuts, while maintaining the template system level or perpendicular to a horizontally or vertically plumb line. Embodiments of such a new and novel template system are herein provided as described and illustrated below in enabling detail.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1
illustrates an outline for an opening to be cut into a section of drywall, for both a single and a dual gang box opening, located adjacent to, and aligned with a vertical framing stud within a wall, to which a gang box is to be mounted. Drywall
11
covers stud
13
as is typical in the construction of a wall. Typically the outline of a rectangular cutout for a gang box is marked or scribed upon the outer surface of drywall
11
, in a preferred position for installing either a single or dual gang box to stud
13
. In order for proper alignment of the newly installed gang box, the left vertical edge of the cutout outline, represented by line
20
in the illustration, is adjacent to, and aligned with the right vertical edge of stud
13
, represented as surface
15
. In the illustration an outline for the cutout required for a single-gang opening is represented by the rectangular shape formed by line
19
intersected by lines
21
and
22
, the rectangular outline having a width of dimension A and height of dimension C. The dual gang opening is approximately twice the width of the single gang opening described above, represented by line
17
intersected by lines
21
and
22
, the dual-gang outline having a width represented by dimension B, and sharing the height of dimensions C with the single-gang opening outline.
It is well known in the art that not in all situations will stud
13
be perfectly level with a vertical line, as is illustrated in FIG.
1
. It is preferred, however, when cutting the outline of the gang box opening, that the opening be as close to perfectly square as possible, and also is oriented such that the top and bottom horizontal edge of the opening is level to horizontal (line A), and the left and right vertical edges of the opening are plumb and perpendicular to the horizontal line.
In order to achieve the square and level gang box opening cutout of
FIG. 1
for mounting a single or dual gang box to stud
13
, stud
13
must first be accurately located through drywall
11
for the purpose of properly positioning the reference point for beginning the marking or cutting, or for correctly positioning a hand-held template for marking or cutting. The location for the reference point for the cutout must be determined relative to surface
15
of stud
13
. In the illustration such a reference point may be the intersection of horizontal line A with vertical line B.
In conventional art there are many method steps and different devices required for determining the exact location of stud
13
, and marking the reference point for the outline for the cutout so as to enable the desired square and level cutout, correctly positioned relative to stud
13
. An electronic stud finder device, for example, may be used to locate the approximate location of surface
15
of stud
13
, a mark made on drywall
11
indicating the location, and then various other separate means and methods for measuring and scribing or cutting along the desired outline are generally required as discussed above.
FIG. 2A
illustrates an improved template system enabled for locating and cutting such a square and level gang box opening properly positioned relative to a framing stud to which a gang box will be attached, according to a preferred embodiment of the present invention. Template system
201
provides an adjustable template for cutting such an opening, enabling accurate location of an outline for a cutout of a predetermined width and height, the outline properly located relative to the location of a stud or other framing member within a wall, ceiling and so forth. Template system
201
enables the average user to easily and affordably perform “old work” stud-mounted gang box installation for new outlet additions to existing electrical wiring and components in a building structure.
Template system
201
in this embodiment comprises a pair of stud finder modules
206
and
207
and an adjustable template system
202
spanning between modules
206
and
207
for guiding a drywall cutting tool, particularly a rotary or spiral type cutting tool, over the outline for the cutout formed by the adjustable template system. Stud finder modules
206
and
207
each contain stud-sensing circuitry according to known technology, preferably utilizing the latest mini-radar sensing technology for accurately reading the exact dimensions and location of the framing stud. In this respect stud finder modules
206
and
207
are functionally equivalent.
Each of module
206
and
207
has a display
209
utilizing known display technology such as LCD or equivalent, for providing the user with visible readings, information and possibly graphics pertaining to the operation and positioning of template system
201
. Each of modules
206
and
207
also has a speaker
212
for providing the user with various audible indicators. Buttons
215
and rotary knob
211
are provided for each of modules
206
and
207
for executing the various functions of modules
206
/
207
, which are further described below, and for selecting display of various information and settings pertaining to the modules' operation and function.
Each of modules
206
and
207
is also provided with a plurality of emitter/receiver elements
219
, one element
219

206
/
207
. Elements
219
are connected to circuitry and a processor (not shown) within modules
206
/
207
enabled for emitting, receiving, reading and processing laser signals. In a preferred embodiment, elements
219
are enabled for laser distance measurement utilizing known technology such as CCD laser displacement sensing that is suitable for measuring the distance between, for example, the inside edges of each module
206
/
207
utilizing the inside-facing elements
219
, or between a top or side edge of module and a wall, ceiling, floor, and so on. The functions of each of elements
219
are separately programmable through activation of one or more of buttons
215
or knob
211
.
The unique template system of the present invention combines the functions of stud location, distance measurement and leveling with an adjustable template system enabling an accurate cut along a precise outline of a predetermined size for a cutout. Modules
206
and
207
each have, extending outwardly and horizontally from the top of each module, a pair of extension arms which fit together to form the top outline of the template, represented by horizontal line A. Module
206
has extension arms
239

206
and
207
in a preferred embodiment, or may otherwise be fixedly attached to the body of modules
206
/
207
using various know means.
Extension arms
231
and
239
, and the outer casing of modules
206
/
207
are preferably formed of high-strength metal alloy that is both rigid and lightweight. The inside dimension of each of tubular arms
231
are slightly larger than the outside diameter of arms
239
, such that the ends of each of arms
239
may be inserted into the ends of arms
231
. Arms
231
are adapted to receive the ends of arms
239
, allowing arms
239
to slide within arms
231
, thereby providing horizontal adjustability to the template system. It is shown in the view that the ends of arms
239
extend slightly into arms
231
, and are secured once the proper adjustment has been achieved utilizing such as set screws
270
, or, in alternative embodiments, a variety of other known clamping means. In the embodiment shown, screws
270
extend through, and rotate freely within threaded holes at the end of arms
231
, and upon tightening, urge into the top surface of arms
239
, thereby securing arms
239
within arms
231
.
The lower portion of template
202
comprises a pair of L-shaped extensions
223
a/b
, and
227
a/b
, each of which is also tubular in nature, similarly to extension arms
231
and
239
of modules
207
and
206
. The inside dimensions at the ends of tubular extensions
223
are slightly larger than the outside dimensions of extensions
227
, such that extensions
227
may be inserted into the ends of extensions
223
, and may slide back and forth within extensions
223
, similarly to extensions
231
and
239
of modules
207
and
206
. Screws
270
are used in this embodiment as described above for extension arms
231
and
239
for securing arms
227
within arms
223
once the proper horizontal adjustment has been achieved.
Each of modules
206
and
207
are provided with an internal track (hidden view) located along the inside vertical edge of each module, adapted for receiving the upper end of each L-shaped extensions set
223
and
227
, and allowing the upper portion of arms
223
and
227
to slide up and down within the vertical tracks. The upper ends of arms
223
extend up into track
291
of module
206
and are secured within track
291
once the proper vertical adjustment has been achieved, utilizing additional screws
270
. The upper ends of arms
227
extend into the bottom of module
207
via track
292
, similarly to arms
223
, and are also secured within track
292
utilizing a set of screws
270
.
The rectangular outline of a cutout to be made, in this case for a gang box opening, is represented in this view by the area within template
202
formed with the intersection of horizontal lines A and D, with vertical lines B and C. It is the object of the present invention as shown in the illustration, to enable the user, using a rotary-type or a reciprocating cutting tool, to easily follow a guideline with the cutting tool for cutting exactly along the desired outline of the cutout. Such a guide for the cutting tool is provided in this embodiment by assembling and securing arms
239
with arms
231
, and securing arms
223
and
227
together, and securing the upper ends of each into modules
206
and
207
.
An L-shaped slot
280
is formed between the separate extending arms
231
a
and
231
b
of module
207
, and a similar slot
282
is formed between arms
239
a
and
239
b
of module
206
, the slots extending completely through each extending arm set such that the cutting bit of a cutting tool may be inserted through the slot and may move within the slot, for making a cut along the outline. Slots
281
and
282
form the upper portion of the outline of the desired cutout as shown in the illustration. A similar pair of L-shaped slots
284
and
286
are formed by the attachment of arms
223
and
227
to each other and into modules
206
and
207
as described, together forming, as shown in the illustration, the lower portion of the outline of cutout. Module
206
has a vertical slot
283
which extends completely through the body of module
206
, and is aligned along the left side of module
206
with the vertical portions of L-shaped slots
282
and
284
, following vertical line B as shown. Module
207
has an equivalent vertical slot
240
located on the right side, aligned with the vertical portions of L-shaped slots
280
and
286
. Together, slots
280
,
282
,
284
and
286
formed by extension arms
231
/
239
and
223
/
227
, and vertical slots
283
and
240
of modules
206
and
207
, form a substantially continuous rectangular-shaped guide for a cutting tool, such that the user, by following the guide provided by the combined slots, the user easily and accurately make the cutout along the outline formed by the area defined by lines A, B, the C and D.
In practice of the present invention, a user wishing to make a cutout in drywall for an opening for a stud-mounted gang box will first determine the size of the opening to be cut, and adjust the size of template
202
horizontally and vertically as described previously, securing the elements of template
202
in the desired position by tightening all of screws
270
. In a preferred embodiment modules
206
and
207
are enabled for determining the vertical and horizontal dimensions of the outline formed by the position of elements of template
202
. Modules
206
and
207
in a preferred embodiment are enabled with programming intelligence and circuitry to determine the width dimension of the outline formed by lines A, B, C and D, as shown in the illustration, by detecting the positions of upper extension arms
231
and
239
relative to each other, and by detecting the positions of lower extension arms
223
and
227
within tracks
291
and
292
of modules
206
and
207
respectively.
Modules
206
and
207
are further enabled with circuitry and functionality (not shown) for communicating with one another, either through wired connection through the extension arms of template
202
, or via wireless infrared communication such as is commonly known, or both. Module
206
, for example, may determine the dimensions of an outline based on the sensed positions of all of the extending arms relative to each other and the position of arms
223
and
227
in tracks
291
and
292
, or may combine the sensed position of arms
223
and
227
with a laser distance measurement through the inward-facing elements
219
. Intercommunication between modules
206
and
207
enables each module to sense the other module's positions of extension arms relative to each other, and locations within tracks
291
and
292
of the extension arms
223
and
227
, with the ability to share this information between them. Either module
206
/
207
, may therefore display through display
209
, initiated by activating one of buttons
215
, for example, the determined dimensions of the outline formed by template
202
.
By utilizing such detection functionality for determining the dimensions of an outline formed by template
202
, modules
206
/
207
may then compare the dimensions of the outline with a dimension that has been pre-programmed into the intelligence of modules
206
/
207
, such as the standard dimensions for a single-gang and dual-gang outlet box cutout, for example, and provide the user with a visual indicator through a display
209
, or an audible indicator through speaker
212
, or both, when such a known dimension is achieved by the adjustment of template
202
.
A preferred embodiment of the invention also enables a user, utilizing one or more of buttons
215
to enter into memory (not shown) within modules
206
or
207
, the exact dimensions of a particular cutout, such that the dimension is saved in memory for recall at a later time. Other means for a user entering such dimension information into modules
206
or
207
may include placing template system
201
upon a printed outline supplied by the manufacturer with a new “old work” gang box, for example, aligning the slot of template
202
with the outline for the cutout, and then, utilizing one or more of buttons
215
, initiating functionality for determining the dimensions of the outline based on the positions of the extension arms, as previously described. A user may then select from memory within modules
206
/
207
, by utilizing rotary knob
211
, for example, various dimensions for different cutouts, and then adjust template
202
to match a selected dimension, and receive a visual and/or audible indication from module
206
/
207
when such a dimension is achieved. Various embodiment of invention may also utilize measurement marks, which may be placed at various locations of the extensions of template
202
or modules
206
/
207
, providing the user with a quick visual reference indicating the dimensions of the outline.
Modules
206
/
207
of template system
201
are enabled for laser distance measurement through elements
219
for determining the distance between a calculated reference point and a wall, a ceiling or a floor, as well as the distance between the inward-facing elements
219
of modules
206
and
207
. Intelligence built into the distance sensing functionality of modules
206
/
207
may calculate, for example, the distance between the floor and the starting reference point for the cutout, and display the information through display
209
. A predetermined measurement, such as a minimum required distance between the floor and outlet box according to building code, may be pre-programmed into memory of modules
206
/
207
, and modules
206
/
207
may then give a visual/audible indicator when template system
201
is positioned on a wall at the proper height such that the lower border of the outline for the cutout, represented as line D in
FIG. 2A
, is at the proper distance from the floor as detected by the laser distance measurement functionality.
Template system
201
is also provided with a pair of levels
210
and
212
, level
210
located horizontally on the upper inner surface of arm
239
b
of module
206
, the other located vertically along the inside edge of module
207
. The user is thereby provided a quick visual indication of whether or not the template is positioned on the wall squared to a horizontal line. In a preferred embodiment modules
206
and
207
are also provided with detecting means (not shown), which detect the status of each level and may then provide a visual indicator through display
209
of the current angle of template system
201
relative to plumb, for example, or may also provide a visual and/or audible indicator when such alignment is achieved. In one embodiment the system uses a magnetometer system for determining level.
Once the dimension of the cutout is determined and template
202
has been adjusted by the user to exactly match said dimension as described above, the exact location for the cutout is then determined utilizing the stud-sensing functionality of either module
206
or
207
, depending on whether the cutout will be located to the right or left of a stud within the wall. For the example given the starting reference point for a cutout that is to be located to the right of the wall stud, will be the intersection of lines A and C, the starting reference point for an opening to be located to the left of a wall stud, being the intersection of lines A and B. Either starting reference point is preferably located adjacent to the left or right side of the wall stud as applicable, as shown in the example given by
FIG. 1
, illustrating the intersection of lines A and B, located adjacent to surface
15
of stud
13
.
Utilizing the stud sensing functionality the user is enabled to locate template system
201
on the wall in the correct position relative to the stud, by receiving a visual/audible indicator from one of modules
206
/
207
when proper alignment is achieved, and the starting reference point of the outline for cutout is in the correct position relative to the wall stud. The user may then move template system
201
up or down in alignment with the wall stud until the predetermined distance is detected between the starting reference point for the cutout and the floor, at which point the user may also receive a visual/audible indicator from one of modules
206
/
207
that the correct distance has been achieved. Once the correct position of template system
201
relative to the wall stud, and correct distance from the floor has been achieved, the user may then rotate template system
201
to level the outline of template
202
to plumb, and also receive a visual/audible indicator from modules
206
/
207
when a perfectly level line has been achieved.
Module
206
has a locator pin mechanism
250
for the purpose of anchoring the right side of template system
201
in its held position over a wall stud after proper location and alignment has been achieved. Module
207
has an equivalent locator pin mechanism
251
for anchoring the left side. In the example described above for placing template system
201
on the drywall at the proper height, angle, and location relative to the wall stud, the user, upon achieving the correct template position for the proposed cutout, activates locator pin mechanism
251
, which drives a pin
253
into the drywall at a downward angle, anchoring the left side of template system
201
to the drywall. The user then verifies that template
201
is level, and activates locator pin mechanism
250
, which drives a pin
254
into the drywall at a downward angle thereby anchoring the right side of template system
201
. Activation of pin mechanisms to
250
and
251
to drive pins
253
and
254
into the drywall may be a manual function performed by the user, or in some embodiments may be automated by the user selecting one of buttons
215
, for example, which may cause an electrically-operated pin driver mechanism, for example, to drive pins
253
and
254
into the drywall. Control means for retracting pins
253
and
254
from the drywall may also be manual or automated in various embodiments without departing from the scope and spirit of the invention. Other alternative embodiments of the present invention may utilize locator pins which permanently protrude somewhat from the bottom of modules
206
/
207
, and securing template system
201
to the drywall may be achieved by simply pressing template system
201
into the drywall after proper location and angle as indicated, thereby urging the locator pins on the back of template system
201
into the drywall, preferably at a slight downward angle.
In a preferred embodiment, once template system
201
is properly positioned and secured to the drywall utilizing the locating pin mechanisms
250
and
251
, the user then utilizes a cutting tool, whose cutting bit has a dimension less than the width of the rectangular slot following the outline of the cutout, to make the cut in the drywall following the guide provided by the rectangular slot in template
202
. The cutting bit, attached to the tool, is adjusted for the proper depth-of-cut according to the thickness of the drywall, and is inserted into the rectangular slot following the outline of the cutout. The user then makes the required cut in the drywall by following the guide provided by the rectangular slot in template
202
along the entire periphery of the outline. Once the cutting is complete, the user then removes template system
201
from the drywall, leaving a cut out section, which is removed to form the desired opening. The cut out section remains in place within the opening, supported only by a small section of drywall which was not cut caused by lifting of the cutting tool out of the slot guide and over support bridges
242
of module
206
, and bridges
243
of module
207
. The user may then simply perform a small cut with a drywall saw or other hand-held cutting utensil, at the four bridge locations to remove the cut out section to form the opening, or simply remove the cut out section by gently tapping on the surface to break the small drywall bridges that remain.

223
and
227
is clearly depicted in this view, extension arms
227
having slightly smaller dimensions than extension arms
223
, allowing for the ends of extension arms
227
to neatly slide into the ends of extension arms

as shown. Extension arms
227
are secured within extension arms
223
by tightening of screws
270
through extension arms

FIG. 3
is an elevation view of a template system according to an alternative embodiment of the present invention. Template system
301
provides an alternative method for following the outline for a cutout with a drywall cutting implement, such as a rotary drywall cutting tool as described with reference to FIG.
2
A. Template system
301
comprises stud finder modules
306
and
307
which are functionally equivalent to modules
206
/
207
of the preferred embodiment described in FIG.
2
A. Modules
306
/
307
are each provided with the same speaker and display, function control, emitter/receiver elements and locator pin anchoring systems and other elements for positioning and leveling template system
301
, for cutting an opening in drywall along an outline defined by the area encompassed by lines A, B, C and D, similarly as described for template system
201
of FIG.
2
A. Modules
306
and
307
also each have an extension arm protruding horizontally, inward from the top of each module, arm
339
from module
306
and arm
331
from module
307
. In this embodiment, however, extension arms
339
and
331
are connected with a center sleeve
335
which is adapted on one end to slide into the end of arm
331
, and on the opposite end to slide over the end of arm
339
, in similar fashion the upper arms of template
201
of FIG.
2
A. Template system
301
also has an L-shaped template extension
323
, one end of which is inserted into track
391
of module
306
, similarly as described for template
201
, and a similar L-shaped extension
327
inserted into track
392
of module
307
. A sleeve
325
connects extensions
327
and
323
similarly as for extensional arms
339
and
331
, also secured in position by tightening screws
370
.
The method used for following the outline for making the drywall cut differs in this embodiment however, in that, instead of following a slotted groove with the rotary drywall cutting tool or other cutting implement, as in template system
201
of
FIG. 2A
, the user follows along the inside edge of the outline formed by the assembled extension arms
339
,
331
,
323
and
327
, and center elements
325
and
335
, following the cutout outline defined by horizontal lines A and D, intersecting with vertical lines B and C, as shown in the view. The configuration of the extension arms and center connectors also extends the limits of adjustability for template system
301
, allowing the user to accurately cut openings much larger than standard single or dual-gang openings.
FIG. 4
is elevation view of a template system according to another alternative embodiment of the present invention. Template system
401
differs from systems
201
of
FIG. 2A and 301
of
FIG. 3
in that only a single stud finder module
406
is utilized for locating the beginning reference point of an outline of a cutout to be made, and providing the squared and level guide along which the user follows with the cutting tool to make the cut. Module
406
is substantially equivalent to the modules of the preferred embodiment described in
FIG. 2A
in both form and functionality, sharing all of the elements as described for function control, display, laser distance measurement, leveling, and so on. Module
406
, however, differs slightly in functionality from module
206
of
FIG. 2A
, in that, due to the single module design of system
401
, added functionality is incorporated enabling the user to locate the starting reference point for the outline of a cut to be made, relative to a detected wall stud, the outline aligned with either side of the wall stud. For instance, if a user wishes to locate and cut an opening for installing a stud-mounted gang box which is to be secured to the left side of a stud, the user would utilize module
406
to locate the stud and identify the stud dimensions and outline, and using the distance measurement, leveling, audible/visual indicators and other functionality as described for the previous embodiments, the user would then position template system
401
on the drywall in the correct position, anchor with the locator pin mechanisms
451
and
452
, and proceed to make the cut with a rotary drywall cutting tool for example, following the guideline provided by the template system. On the other hand, if the user wishes to cut the opening for installing a gang box on the right side of the stud, the user would then invert system
401
such that the template portion of system
401
is positioned to the right of module
406
. Intelligence within module
406
would then, either automatically of by the user invoking a command with one of buttons
415
, for instance, consider the inverted position of the system, and still correctly indicate to the user when the proper distance from the floor, angle and alignment with the wall stud is achieved. The user is thereby enabled to utilize system
401
for making level, squared openings in drywall, regardless of whether the opening will be to the left or right of the wall stud.
Template system
401
utilizes the template elements similar to those described for module
301
of system
301
of
FIG. 3
, having an extension arm
439
extending horizontally from the top of module
406
, with a center extension
435
sliding over arm
439
. In the absence of a second equivalent module as in the previous embodiments described, L-shaped extensions
427
and
431
are provided to form the left portions of the template. The end of the upper portion of extension
431
is adapted to slide over center extension
435
, and the same is true for the lower arm
427
and center extension
425
. Template
401
is shown in this view adjusted to the outline dimensions of a single-gang opening, and may also be secured in position utilizing screws such as previously described, or some other securing means.
As with system
301
of
FIG. 3
, the inner surfaces of the extension elements of template system
401
, forming the rectangular outline defined by lines A, B, C and D, provide the guide for making the cut in the drywall, the user following the outline with the cutting tool while slightly urging the tool outwardly in order to prevent wandering of the cutting tool. Locator pin mechanisms
450
and
452
are equivalent in form and function to those of previously described embodiments, and are similarly employed by the user to project a pin slightly into the surface of the drywall, at a slightly downward angle, for anchoring both sides of the template system to the drywall once it is placed in the correct position for cutting the opening along the determined outline.
FIG. 5A
is an elevation view of a template system module according to another alternative embodiment of the present invention. Module
501
is provided in this embodiment, as a standalone unit which, when used with other like modules and template elements in a template system which will be subsequently described, allows the user to accurately locate the outline for making a large cut in drywall, relative to the location of a hidden wall stud, wherein the size of the opening is much larger than possible with the previous embodiments disclosed above.
Module
501
contains stud-sensing circuitry according to known technology, preferably utilizing the latest mini-radar sensing technology for accurately reading the exact dimensions and location of the framing stud. In this respect module
501
is functionally equivalent to module
206
of FIG.
2
A.
Module
506
also has a display
509
utilizing known display technology such as LCD, for providing the user with visible readings, information and possibly graphics pertaining to the operation and positioning of module
506
, and a speaker
512
for providing the user with various audible indicators. Buttons
515
are provided for executing the various functions of module
506
, which is further described below, and for selecting display of various information and settings pertaining to the modules' operation and function. Levels
510
and
512
provide the leveling capability of the unit, as with previously described embodiments.
Module
506
is also provided with a plurality of emitter/receiver elements
519
, one element
519
located on each of the top, bottom, left and right sides of module
506
. Elements
519
are connected to circuitry and processor (not shown) within module
506
enabled for emitting, receiving, reading and processing laser signals. Elements
519
are enabled as in previously described embodiments for laser distance measurement utilizing known technology that is suitable for measuring the distance between, for example, the distance between module
506
and a wall, ceiling, floor, or another module
506
. The functions of each of elements
519
are separately programmable through activation of one or more of buttons
515
.
Locator pin mechanisms
550
and
551
and pins
552
and
553
, which are also similar to those used in module
206
of
FIG. 2A
, are also provided in this embodiment for the purpose of anchoring module
506
in its held position over a wall stud after proper location and alignment has been achieved. Activation of pin mechanisms to
550
and
551
to drive pins
552
and
553
into the drywall may be a manual function performed by the user, or may be automated by the user selecting one of buttons
215
, for example, which cause the pin driver mechanism to drive pins
552
and
553
slightly into the drywall, at a downward angle. Control means for retracting pins
553
and
554
from the drywall may also be manual or automated without departing from the scope and spirit of the invention.
Module
506
is provided with a rotating mounting apparatus
560
, which rotates freely within module
506
, and contains two pairs of small slots
563
extending from the surface downward into apparatus
560
. Apparatus
560
is provided for attaching the end of a template element as is further detailed below.

FIG. 6
is an elevation view of a plurality of template system modules
506
of
FIG. 5A
, interconnected with template guide rails according to an embodiment of the present invention. Template system
60
, as will be described, allows the user to accurately locate the outline for making a large cut in drywall, relative to the location of a hidden wall stud, wherein the size of the opening is much larger than possible with the previous embodiments disclosed above.
An example of an application where system
601
might be used is for making a level and perfectly squared opening in a wall covered with drywall, for installing a recessed medicine cabinet, for instance, into a wall, wherein it is necessary for both the left and right sides of the opening to be aligned with wall studs such that the medicine cabinet may be attached directly to the studs.
Template system
601
comprises a pair of modules
506
and a pair of modules
507
, modules
506
located at the top left and bottom left corners of a rectangle, modules
507
being located at the top and bottom corners at the right of the rectangle. Modules
506
and
507
are physically and functionally equivalent to each other, with the exception that modules
507
differ slightly from modules
506
in that the arrangement of all of the elements on the surface of modules
507
is opposite to that of modules
506
, allowing for arranging them in a pattern as shown for making the large cut. For instance, module
506
has the rotating element
560
located in the lower right corner, and module
507
has an equivalent rotating element
562
located in the lower right corner.
A set of four adjustable template guide rails
605
are provided in this embodiment, for the purpose of providing the guide along which the user will follow with a rotary drywall-cutting tool, for example, when making a cut. Guide rails
605
each comprise multiple sections
605
a
-
d
which are adapted for one section to slide back and forth within another, similarly to the adjustable template systems previously described. Sections
605
a
and
605
d
are each adapted on one end, as shown later in greater detail, to attach to the rotating elements
560
or
562
of modules
506
and
507
, such that one guide rail
605
may span and interconnect a pair of modules
506
or
507
, as shown in the figure.
Each of center sections
605
b
and
605
c
have a slot
640
spanning the entire length of the section and extending completely through, and each of end sections
605
a
and
605
d
have a similar slot, except that instead of extending the entire length, the slot terminates close to the end which is attached to rotating elements
560
/
562
of modules
506
/
507
.
In practice of the embodiment shown by
FIG. 6
, the example shows the outline of a large cutout to be made, represented by the area encompassed by intersecting lines A, B, C and D. The cutout to be made in this example spans horizontally from one hidden wall stud (not shown) to another. The user will first locate the wall stud, which will border the left of the outline, utilizing the stud sensor functionality of a first module
506
. Distance measurement functionality in module
506
as described enables placement of module
506
at the desired height from the floor. Once module
506
is aligned with the hidden wall stud and at the proper height, module
506
is leveled using levels
510
and
512
, and then locator pin mechanisms
550
and
551
are activated to anchor module
506
in its proper location to the surface of the drywall.
With the first module now in place at the upper left corner of the proposed cutout, and perfectly leveled to plumb, the remaining three modules of the system may be positioned. As previously mentioned, module
506
is enabled for laser distance measurement utilizing circuitry and functionality within module
506
, and emitter/receiver elements
519
located on each of the four sides of module
506
. In this embodiment, however, modules
506
and
507
are also enabled for emitting a laser beam through any of elements
519
, and are also capable of reading an emitted laser beam from any other module
506
or
507
.
For locating and placing the second module in the system (module
507
, top right), the user will first locate the hidden wall stud which will border the right side of the proposed cutout, utilizing the stud sensing functionality of module
507
. Once the proper position for module
507
is determined relative to the right-side wall stud, the user will then activate such as one of buttons
515
of module
506
, to emit a visible laser beam
590
horizontally from an element
519
on the side of module
506
, towards the second module (
507
). Since the first module (
506
) is now positioned at the upper left corner of the proposed cutout, and is anchored to the drywall perfectly squared to a horizontal line, the laser beam
590
is emitted from module
506
following a perfectly horizontal line. Elements
519
of modules
506
and
507
are also enabled for detecting such an emitted laser beam from another module, and the second module (
507
) which will be placed at the upper right of the outline detects, through an element
519
on the side of module
507
facing module
507
, the emitted laser beam from module
506
, and when module
507
is aligned horizontally with module
506
, thereby indicating the correct height for module
507
, module
507
provides a visible/audible indicator to the user that such horizontal alignment has been achieved. Leveling functionality in module
507
enables the user now to position module
507
perfectly squared to module
506
.
With module

507
to emit a perfectly horizontal laser beam to the left for aligning a fourth module (
506
lower-left) such that the fourth module may be correctly positioned relative to the remaining three modules, which have already been located, squared and anchored to the drywall. The fourth module is then anchored at the lower left corner of the outline utilizing pin locator mechanisms as described, and one end of a third guide rail
605
is then attached to rotating element
562
, the other end extended towards the fourth module
506
, and attached to rotating element
560
of the final module
506
. Once modules
506
and
507
have been positioned and anchored, and all guide rails
605
have been attached at both end to modules
506
/
507
, a squared and level template is thereby provided for cutting a large opening between two wall studs, wherein the user follows the guide provided by slot
640
of guide rails
605
with the cutting tool around the entire outline completing the rectangle.

Although the present invention has been described in the various embodiments above to be adapted for use in locating and cutting rectangular shaped openings in “old work” gang box installation applications, and for locating and cutting other larger openings in drywall or other such wall covering, the present invention may be adapted for providing a guide for cutting openings of a variety of sizes and shapes, which may or may not be necessarily aligned with a wall stud. For example, template module systems according to the present invention may be used for cutting openings which are located on the wall based only on the measured distance between the module and a wall, floor or ceiling, as detected by the distance measuring functionality of the module as described. Furthermore, adjustable template systems integrated with modules as described above, or adjustable guide rails for use with separate modular units, such as described in
FIGS. 6 and 7
, may be adapted to provide a guide for a cutting tool other than the rotary cutting tool as described above for the various embodiments, such as a hand-held drywall saw, jigsaw or other common drywall cutting implement, without departing from the scope and spirit of the invention. Still further, the functionality for distance measurement, leveling, and intercommunication between modules of a template system may utilize various known technologies enabling the functionality, and should not be limited only those technologies herein disclosed.
