FRAMING
BACKGROUND OF THE INVENTION
(1) Field of the Invention The invention pertains generally to a safety tool for the construction industry. More specifically, the invention relates to a hand protector for protecting against accidents from stray nails when wood stud framing.
(2) Description of the Related Art Wood stud framing involves framing up the walls of rooms and other structures.
Typically, a plurality of 2" by 4" inch boards are laid on the ground and nailed together in the particular formation of a wall, often utilizing eight inch "on center" spacing. For instance, a plurality of studs may be nailed with eight inch spacing from one another between a top plate and a bottom plate.
For speed and convenience, wood stud framing in professional settings is usually performed utilizing nail guns. For safety purposes, a user must take care to keep their hands sufficiently far enough away from where the nail will enter the wood. The further away the better in case the nail hits a knot in the wood or the nail gun is misdirected.
Ideally, boards should be connected such that they are both plumb and flush.
Plumb refers to making a perpendicular connection such as a stud meeting a top plate at a ninety degree angle.
Flush refers to the edges of the boards being level with one another such as the side edge of a stud being exactly level with the side edge of a top plate.
The easiest way to ensure that boards are connected together both plumb and flush would be to hold one of the boards at a position very close to where it will be nailed to the other board to manually ensure both the angle is correct and the sides are level with each other. However, holding the boards so close to the point where the nail will enter the wood is extremely risky.
FIG. 1 shows an example of an accident caused by a stray nail when framing according to the related art. Especially when utilizing a nail gun, having one's hand too close to the point of connection between the two boards is dangerous. In an attempt to ensure boards are plumb and flush, a user has an incentive to hold the new board as close to point of nailing as possible.
Accidents may occur if a user inadvertently holds a board too close to the connection and a stray nail is shot into the user's fingers or hand.
BRIEF SUMMARY OF THE INVENTION
According to an exemplary embodiment of the invention there is disclosed a hand protector protecting against accidents from stray nails when framing. The hand protector includes a base running in a forward direction from a back end to a front end, the base further having a top side, a bottom side, a first side, and a second side. A first sidewall extends in a downward direction away from the first side of the base. A first nail stop wall extends laterally away from the first side of the base. The first nail stop is substantially perpendicular to the first sidewall, and the first nail stop wall extends away from the first side of the base at a predetermined lengthwise distance along the base such that the first nail stop wall is closer to the front end of the base than to the back end of the base. A second sidewall extends in the downward direction away from the second side of the base. A second nail stop wall extends laterally away from the second side of the base. The second nail stop is substantially parallel to the first nail stop wall and perpendicular to the second sidewall.
The second nail stop wall extends away from the second side of the base at substantially the predetermined lengthwise distance along the base such that the second nail stop and the first nail stop are both in a same plane.
In addition to protecting a user's hands, an exemplary advantage of some embodiments is that the hand protector further acts an alignment tool to help the user ensure boards are nailed both plumb and flush.
These and other advantages and embodiments of the present invention will no doubt become apparent to those of ordinary skill in the art after reading the following detailed description of preferred embodiments illustrated in the various figures and drawings.

DETAILED DESCRIPTION
FIG. 2 shows a perspective view of a hand protector 200 for protecting against accidents from stray nails when wood stud framing according to an exemplary embodiment. The hand protector 200 includes a base 202, a first sidewall 204a, a second sidewall 204b (hidden in FIG. 2 but visible in FIG. 3, for example). A sidewall hinge 206 runs along a corner of the base 202 intermediate the base 202 and the second sidewall 204b. The base section in this embodiment includes a substantially rectangular shape and runs from a back end 208 to a front end 210. The front end 210 in this embodiment includes a W-shaped end that includes a V-notch 212 located on the front, center end 210 of the base 202.
A first nail stop wall 214a extends away from the right-side of the base 202 and a second nail stop wall 214b extends away from a left side of the base 202. In this embodiment, the nail stop walls 214a, 214b are integral sections of the sidewalls 204a, 204b. For instance, the right-side nail stop wall 214a is formed by a ninety degree bend of the material forming the right sidewall 204a.
Likewise, the left-side nail stop wall 214b is formed by a ninety degree bend of the material forming the left sidewall 204b. In this embodiment, for additional strength, each of the first and second nail stop walls 214a, 214b are formed by double layer of the wall material and include a plurality of internal supporting structures 216 to facilitate additional strength against stray nails hitting said nail stop walls 214a, 214b from the front.
In this embodiment, the W-shaped front end 210 of the base 202 extends past the front side 218 of the nail stop walls 214a, 214b by approximately 3/4 of an inch such that the tip of the V-notch 212
4 is at a center position of a board positioned adjacent the front edges 218 of the nail stop walls 214a, 214b. The length of the base 202 running toward the back end 208 behind the nail stop walls 214a, 214b is approximately four inches to accommodate a placement of a user's palm.
As illustrated, the first and second sidewalls 204a, 204b are substantially perpendicular to first and second nail stop walls 214a, 214b. The combination of the base 202 and the sidewalls 204a, 204b rotated as shown in FIG. 2 form a rectangular empty section between them into which a first board to be nailed can be inserted. The bottom side 220 of the base 202 rests against the top side of the first board and the two side walls 204a, 204b extend downwards on either side of the first board.
The first and second nail stop walls 214a, 214b are parallel one and another and are both located in a same plane such that the front side 218 of the two nail stop walls 214a, 214b can be abutted against a second board to be nailed.
FIG. 3 illustrates a front view of the hand protector 200 of FIG. 1 with the second sidewall 204b rotated upwards such that the hand protector 200 is configured in an open configuration according to an exemplary embodiment. As illustrated, the second sidewall 204b is rotated upwards around the sidewall hinge 206 intermediate the base 202 and the second sidewall 204b such that second sidewall 204b is now roughly parallel with the base 202. The open configuration of the hand protector 200 is useful to allow a board 222 to be nailed to be inserted. In some embodiments, the sidewall hinge 206 includes a spring that is biased to by default open the hand protector 200 into the open configuration as shown in FIG. 3. A user can then overcome the spring force in order to rotate the second sidewall 204b around the sidewall hinge 206 in order to change the hand protector 200 into a working configuration.
FIG. 4 illustrates a front view of the hand protector 200 of FIG. 1 with the second sidewall 204b rotated downwards such that the hand protector 200 is configured in the working configuration according to an exemplary embodiment. In the working configuration, the board 222 can be frictionally gripped as it is sandwiched between the first and second sidewalls 204a, 204b. The working configuration allows the board 222 to be grabbed by a user with a palm of the user's hand on the top side 224 of the base 202, fingers of the user's hand on a first side wall 204a and thumb of the user's hand on a second sidewall 204b. The user can grip the sidewalls 204a, 204b (pull fingers and thumb toward one another) in order to hold and manipulate the board 222.
As illustrated, the first and second sidewalls 204a, 204b are substantially perpendicular to first and second nail stop walls 214a, 214b. The combination of the base 202 and the sidewalls 204a, 204b rotated as shown in FIG. 2 form a rectangular empty section between them into which a first board to be nailed can be inserted. The bottom side 220 of the base 202 rests against the top side of the first board and the two side walls 204a, 204b extend downwards on either side of the first board.
The first and second nail stop walls 214a, 214b are parallel one and another and are both located in a same plane such that the front side 218 of the two nail stop walls 214a, 214b can be abutted against a second board to be nailed.
FIG. 3 illustrates a front view of the hand protector 200 of FIG. 1 with the second sidewall 204b rotated upwards such that the hand protector 200 is configured in an open configuration according to an exemplary embodiment. As illustrated, the second sidewall 204b is rotated upwards around the sidewall hinge 206 intermediate the base 202 and the second sidewall 204b such that second sidewall 204b is now roughly parallel with the base 202. The open configuration of the hand protector 200 is useful to allow a board 222 to be nailed to be inserted. In some embodiments, the sidewall hinge 206 includes a spring that is biased to by default open the hand protector 200 into the open configuration as shown in FIG. 3. A user can then overcome the spring force in order to rotate the second sidewall 204b around the sidewall hinge 206 in order to change the hand protector 200 into a working configuration.
FIG. 4 illustrates a front view of the hand protector 200 of FIG. 1 with the second sidewall 204b rotated downwards such that the hand protector 200 is configured in the working configuration according to an exemplary embodiment. In the working configuration, the board 222 can be frictionally gripped as it is sandwiched between the first and second sidewalls 204a, 204b. The working configuration allows the board 222 to be grabbed by a user with a palm of the user's hand on the top side 224 of the base 202, fingers of the user's hand on a first side wall 204a and thumb of the user's hand on a second sidewall 204b. The user can grip the sidewalls 204a, 204b (pull fingers and thumb toward one another) in order to hold and manipulate the board 222.
5 FIG. 5 illustrates a top view of the hand protector 200 of FIG. 1 in the working configuration and holding a board 222 according to an exemplary embodiment. As shown in this example, the hand protector rests on a top surface 226 of the board 222.
FIG. 6 illustrates a perspective view of usage of a hand protector 200 with integrated forearm brace 228 to help prevent accidents from stay nails when framing according to an exemplary embodiment. In this example, the hand protector 200 is being utilized to protect a user's hand while nailing a stud board 222 to a top plate board 230. Prior to the view shown in FIG. 6, the user grabbed the stud board 222 utilizing the hand protector 200 similar to a claw.
For example, the hand protector 200 was opened by the user into the open configuration and was positioned with the stud board 222 inserted into the protector 200 as shown in FIG. 3. The rotatable sidewall 204b was then rotated downward into the working configuration and the stud board 222 was picked up by the user. The user then carried the stud board 222 in the hand protector 200 and positioned the stud board 222 to abut against the top plate board 230 forming a T-connection. The user then slightly releases the pressure on their grip such that the sidewalls 204a, 204b of the hand protector 200 can slide along the stud board 222 toward the T-connection such that the first and second nail stop walls 214a, 214b abut against the side surface 232 of the top plate board 230 as illustrated in FIG. 3. At this time, the user's hand is very close to the T-connection between the two boards 222, 230 and the user can easily ensure the joint is both plumb and flush.
The design of the hand protector 200 in this embodiment assists with ensuring the joint is both plumb and flush. Because the sidewalls 204a, 204b and the nail stop walls 214a, 214b are perpendicular to one another in the working configuration, by sliding the hand protector 200 along the stud board 222 right up to the joint until both the nail stop walls 214a, 214b reach and press against the side 232 of the top plate board 230, the angle that the boards 222, 230 meet each other will be very close to ninety degrees. Likewise, because the base 202 extends forward past a point at which the nail stop walls 214a, 214b extend laterally out from the base 202, by pressing downward on the hand protector 200 such that top sides 234, 236 of both the stud board 222 and the top plate board 230 are pressing against the bottom side 220 of the base 202, the top sides 234, 236 of the stud board 222 and the top plate board 230 are ensured to be very close to level.
Beneficially, the hand protector 200 allows the user to have their hand positioned very close to the joint to be nailed by the nail gun 238 while still being protected from stay nails. The joint is the
FIG. 6 illustrates a perspective view of usage of a hand protector 200 with integrated forearm brace 228 to help prevent accidents from stay nails when framing according to an exemplary embodiment. In this example, the hand protector 200 is being utilized to protect a user's hand while nailing a stud board 222 to a top plate board 230. Prior to the view shown in FIG. 6, the user grabbed the stud board 222 utilizing the hand protector 200 similar to a claw.
For example, the hand protector 200 was opened by the user into the open configuration and was positioned with the stud board 222 inserted into the protector 200 as shown in FIG. 3. The rotatable sidewall 204b was then rotated downward into the working configuration and the stud board 222 was picked up by the user. The user then carried the stud board 222 in the hand protector 200 and positioned the stud board 222 to abut against the top plate board 230 forming a T-connection. The user then slightly releases the pressure on their grip such that the sidewalls 204a, 204b of the hand protector 200 can slide along the stud board 222 toward the T-connection such that the first and second nail stop walls 214a, 214b abut against the side surface 232 of the top plate board 230 as illustrated in FIG. 3. At this time, the user's hand is very close to the T-connection between the two boards 222, 230 and the user can easily ensure the joint is both plumb and flush.
The design of the hand protector 200 in this embodiment assists with ensuring the joint is both plumb and flush. Because the sidewalls 204a, 204b and the nail stop walls 214a, 214b are perpendicular to one another in the working configuration, by sliding the hand protector 200 along the stud board 222 right up to the joint until both the nail stop walls 214a, 214b reach and press against the side 232 of the top plate board 230, the angle that the boards 222, 230 meet each other will be very close to ninety degrees. Likewise, because the base 202 extends forward past a point at which the nail stop walls 214a, 214b extend laterally out from the base 202, by pressing downward on the hand protector 200 such that top sides 234, 236 of both the stud board 222 and the top plate board 230 are pressing against the bottom side 220 of the base 202, the top sides 234, 236 of the stud board 222 and the top plate board 230 are ensured to be very close to level.
Beneficially, the hand protector 200 allows the user to have their hand positioned very close to the joint to be nailed by the nail gun 238 while still being protected from stay nails. The joint is the
6 point at which one or more nails will enter the boards and join them together.
If the nail is fired straight it will pass through the top plate 236 and into the end of the stud board 222 thereby making a solid joint. This is the expected and desired action. However, if there is a knot in the wood or if the nail gun 238 is not being held at the exact correct angle or if any one of a plurality of other unforeseen circumstances occur, the nail may be diverted from its proper angle and may fire toward the user's hand. In this case, the hand protector 200 acts as a shield because the various angles that the nail is likely to pass are blocked by the hand protector 200. The base 202 protects the palm of the user's hand. The sidewalls 204a, 204b protect the user's fingers and thumb from nails that may come out the sides of the stud board 222. The nail stop walls 214a, 214b protect the user's fingers and thumb from nails that are misfired from the front such as nails that completely miss the stud board 222 entirely.
A misfired or otherwise stray nail will tend to impact one of the surfaces of the hand protector 200 and be stopped. In this embodiment, each of the base 202, sidewalls 204a, 204b, and nail stop walls 214a, 214b is made of a solid material such as stainless steel that has strength sufficient to stop the impact of a nail fired by the nail gun 238. The base 202 and sidewalls 204a, 204b in this embodiment are a single layer of the material as it likely that any nails that impact on the base 202 or the sidewalls 204a, 204b will have a tangential angle. The nail stop walls 214a, 214b in this embodiment are double layer to further add reassurance and safety in case a nail is directly shot by the nail gun 238 into the nail stop walls 214a, 214b from the front.
The hand protector 200 of FIG. 6 further includes several other features. For one, a pencil holder 240 is provided on the top surface 224 of the base 202 allowing a user to hold a carpenter's pencil 242 within the tool 200 at all times. The pencil 242 can be positioned such that its writing tip is located right at the V-notch 212 on the front end 210 of the base 202 such that the user can make marks on a board 222, 230 without removing the pencil 242 from the hand protector 200 if so desired.
Another feature illustrated in the embodiment of FIG. 6 is the addition of a forearm brace 228 that wraps around the forearm of the user. The forearm brace 228 is coupled to the base 202 of the hand protector 200 by a cord 244 that may a flexible wire such as airplane wire. A
benefit of the forearm brace 228 being attached to the hand protector 200 is to prevent the hand protector 200 from being accidentally dropped onto another worker that may be working below where the framing is taking
If the nail is fired straight it will pass through the top plate 236 and into the end of the stud board 222 thereby making a solid joint. This is the expected and desired action. However, if there is a knot in the wood or if the nail gun 238 is not being held at the exact correct angle or if any one of a plurality of other unforeseen circumstances occur, the nail may be diverted from its proper angle and may fire toward the user's hand. In this case, the hand protector 200 acts as a shield because the various angles that the nail is likely to pass are blocked by the hand protector 200. The base 202 protects the palm of the user's hand. The sidewalls 204a, 204b protect the user's fingers and thumb from nails that may come out the sides of the stud board 222. The nail stop walls 214a, 214b protect the user's fingers and thumb from nails that are misfired from the front such as nails that completely miss the stud board 222 entirely.
A misfired or otherwise stray nail will tend to impact one of the surfaces of the hand protector 200 and be stopped. In this embodiment, each of the base 202, sidewalls 204a, 204b, and nail stop walls 214a, 214b is made of a solid material such as stainless steel that has strength sufficient to stop the impact of a nail fired by the nail gun 238. The base 202 and sidewalls 204a, 204b in this embodiment are a single layer of the material as it likely that any nails that impact on the base 202 or the sidewalls 204a, 204b will have a tangential angle. The nail stop walls 214a, 214b in this embodiment are double layer to further add reassurance and safety in case a nail is directly shot by the nail gun 238 into the nail stop walls 214a, 214b from the front.
The hand protector 200 of FIG. 6 further includes several other features. For one, a pencil holder 240 is provided on the top surface 224 of the base 202 allowing a user to hold a carpenter's pencil 242 within the tool 200 at all times. The pencil 242 can be positioned such that its writing tip is located right at the V-notch 212 on the front end 210 of the base 202 such that the user can make marks on a board 222, 230 without removing the pencil 242 from the hand protector 200 if so desired.
Another feature illustrated in the embodiment of FIG. 6 is the addition of a forearm brace 228 that wraps around the forearm of the user. The forearm brace 228 is coupled to the base 202 of the hand protector 200 by a cord 244 that may a flexible wire such as airplane wire. A
benefit of the forearm brace 228 being attached to the hand protector 200 is to prevent the hand protector 200 from being accidentally dropped onto another worker that may be working below where the framing is taking
7 place. Another benefit is to allow the user that is utilizing the hand protector 200 to temporarily mount the hand protector 200 onto the forearm brace 228 in order to free up both their hands for other tasks.
For mounting, the forearm brace 228 in this embodiment includes a magnet 246 mounted thereon, and when desired, the user can move the metal base 202 of the hand protector 200 adjacent to the magnet 246 to thereby temporarily attach the hand protector 200 to the forearm brace 228. Of course, the magnet 246 needs to be of sufficient strength such that its magnetic force is sufficient to overcome the force of gravity pulling down on the hand protector 200 including the optional pencil 242 and cord 244.
In this embodiment, the forearm brace 228 further includes a cord retractor 248 that automatically retracts slack cord 244. The cord retractor 248 may be formed by a washer, nut, or other stopper element welded to an end of the cord 244 within the retractor. A cord spring may be intermediate between the stopper unit and a front inner surface of the cord retractor 248.
By overcoming the force of the cord spring, the user can pull out the cord 244 from the retractor unit 248; however, slack cord 244 will be automatically pulled back into the retractor 248 by the force of the spring pushing the stopper unit away from the front inner surface of the cord retractor 248.
In addition to metal wire cords 244, other types of cords 244 may also be utilized. For example, soft flexible cords 244 such as bungee type line may be utilized in other embodiments. The cord 244 itself may be elastic thereby possibly negating the cord retractor 248, which may therefore be omitted in some embodiments.
FIG. 7 illustrates a top view of a hand protector 200 with integrated forearm brace 228 and measuring rod 250 while the protector 200 is in an open configuration according to an exemplary embodiment.
The hand protector 200 in this embodiment includes a forearm brace 228 with integrated magnet 246 and cord retractor 248. Hook and loop material such as Velcro is provided to allow the forearm brace to be secured around the user's forearm. The cord 244 connects from the retractor 248 to a pivot joint 252 that can rotate 360 degrees and also bend over 180 degrees. A pencil holder 240 is mounted on the top side 224 of the base 202 and a side wall 204b is rotated about a sidewall hinge 206 in the upwards direction such that a board 222 can easily be inserted into the space under

FIG. 11 illustrates a top view showing a method of utilizing the measuring rod 250 of the hand protector 200 of FIG. 7 according to an exemplary embodiment. As shown, a user may extend the measuring rod sections 256a, 256b such that the measuring rod 250 is substantially parallel with the nail stop walls 214a, 214b. The user can grab a stud board 222 and position it to be nailed to a top plate board 230. Beneficially, the desired spacing such as eight inch center spacing can be
9 achieved without any measuring. The user simply needs to abut the end 260 of the measuring rod 250 against the side of a previously nailed stud board 262.
Although eight inch on center spacing is common, the measuring rod 250 and/or sections 256a, 256b thereof may of course be changed in size to accommodate any desired spacing. In some embodiments, the measuring rod 250 is telescoping to allow the user to set a desired distance.
Likewise, rather than or in addition to a pivot 258 between measuring rod sections 256a, 256b, a slider track may be utilized between the rods 256a, 256b to allow one or more sections 256a, 256b to slide relative the other in order to extend or reduce the overall measuring rod 250 distance. A
locking screw or other friction hold device may lock into place the sections 256a, 256b to prevent further sliding after the desired distance is set. The measuring rod 250 may also be removable and installable by the user. A kit may be provided with a plurality of different measuring rods 250 for different desired spacings.
FIG. 12 illustrates a top view of a hand protector 300 with a sideways rotatable nail stop wall 302a according to an exemplary embodiment. In this embodiment, the nail stop walls 302a, 302b are single layer walls of sufficient width to prevent passage of a nail that impacts a front of the wa11302a, 302b. Further, a first one of the nail stop walls 302a includes a nail stop hinge 304 running vertically along the edge of the nail stop wall 302a that couples the nail stop wall 302a to the sidewall 204a and/or base 202. The nail stop hinge 304 allows the nail stop wall 302a to be rotated backwards such that the first nail stop wall 302a is parallel the adjacent first sidewall 204a.
A stopper 306 is included adjacent the hinge 304 to ensure that, when rotated forward, the nail stop wall 302a will be perpendicular to the sidewall 204a.
FIG. 13 illustrates a front view of a hand protector 400 with an upwards rotatable nail stop walls 402a, 402b and protruding L-shaped clip 404 according to an exemplary embodiment.

The nail stop walls 214a, 302a, 402a, 214b, 302b, 402b may fold upwards for storage.
Although the invention has been described in connection with preferred embodiments, it should be understood that various modifications, additions and alterations may be made to the invention by one skilled in the art without departing from the spirit and scope of the invention.
For instance, although various features such as hinges, pivot points, springs, measuring rod, pencil holder, clips etc. are illustrated on one or more particular sides of the hand protector 200, 300, 400, in other embodiments, these features may be on another side or on multiple sides of the hand protector 200, 300, 400. In one example, a measuring rod 150 may be provided on both the right and the left sides to allow easy framing spacing regardless of the order the stud boards are attached to the top or bottom plates. Likewise, a pivot mount point 258 for the measuring rod 150 may be provided on both the right and left sides allowing a single measuring rod 150 to be swapped from the right side to the left side by the user according to the user's preferences. This may be beneficial to match a user preference depending on whether the user is left handed or right handed, or may be beneficial depending on the work site location and existing boards such as for when framing boards that are already standing up.
Although the above disclosure has focused on protecting a user's hand while framing wood studs, the hand protector 200, 300, 400 may also be used in a similar manner with other types of framing or nailing of boards. Framing may be done with boards lying on ground or tool may be utilized for standing work.
The nail stop walls may be single layer or double layer for added protection.
Likewise, any of the base and/or sidewalls may be single layer or double layer for added protection.
As illustrated in FIG. 4, the second sidewall 204b can rotate such that it impacts the board 222 and allows the board 222 to be enclosed between the sidewalls 204a, 204b even if the board 222 is narrower than the width of the base 202. In some embodiments, an inner surface of the sidewalls 204a, 204b adjacent the board 222 may have a griping layer such as a rubber coating or grip tape in order to increase friction. The gripping layer may be removable such as being held in place by a hook and loop attachment or snaps such that it can be utilized in certain conditions such as rainy days with wet boards, and removed for other conditions such as sunny days with dry boards.
Likewise, a griping layer may be provided on the top side 224 of the base 202 and/or outsides of the sidewalls 204a, 204b to facilitate a user holding the hand protector 200.
Although some of the above embodiments have shown a magnet 246 attached to the forearm brace 228 for attracting and holding the metal base 202; other combinations of ferromagnetic attachments may be utilized. For instance, a magnet may be attached to the base or other element of the hand protector and a piece of metal mounted to the forearm brace. Likewise, both the forearm brace and the base may have respective magnets mounted thereto. In this case, the polarities of the magnets are configured such that the N pole of one magnet and attach to the S pole of another magnet in order to attach the protector to the forearm brace.
The various methods of protecting against accidents from stray nails when framing utilizing hand protectors as disclosed herein are according to exemplary embodiments. The steps of positioning and operating the hand protector 200, 300, 400 may be performed by a human user of the hand protector 200, 300, 400. The steps as disclosed are not restricted to the exact order shown or described, and, in other configurations, shown and described steps may be omitted or other intermediate steps added.
Functions of single elements and parts of the hand protector may be separated into multiple units, or the functions of multiple elements and parts may be combined into a single unit. For example, in some embodiments, the base is integral with one or more of the sidewalls and/or the nail stop walls. In some embodiments, a nail stop wall may be integral to a sidewall.
All combinations and permutations of the above described features and embodiments may be utilized in conjunction with the invention.
Although eight inch on center spacing is common, the measuring rod 250 and/or sections 256a, 256b thereof may of course be changed in size to accommodate any desired spacing. In some embodiments, the measuring rod 250 is telescoping to allow the user to set a desired distance.
Likewise, rather than or in addition to a pivot 258 between measuring rod sections 256a, 256b, a slider track may be utilized between the rods 256a, 256b to allow one or more sections 256a, 256b to slide relative the other in order to extend or reduce the overall measuring rod 250 distance. A
locking screw or other friction hold device may lock into place the sections 256a, 256b to prevent further sliding after the desired distance is set. The measuring rod 250 may also be removable and installable by the user. A kit may be provided with a plurality of different measuring rods 250 for different desired spacings.
