- This application relates generally to a framing guide for use in construction.
- the application relates more particularly to a guide for positioning studs for framing dwellings and buildings.
- Framing configurations can include structures such as trusses, gables, rafters, joists, sill plates, posts, supports, scaffolding, and so forth. Different sizes and grades of wood can be used depending on the structural necessities of the particular part of a structure being framed. For example, studs such as two-by-fours are commonly used to frame wall sections where the forces are generally vertical, while two-by-six or bigger studs are common for floor joists which have to support substantial horizontal forces as well.
- Some configurations utilize wood beams placed at right angles to one another.
- studs used to frame wall sections are generally in horizontal and vertical orientations. These configurations tend to be relatively easy to position and secure to one another as the various surfaces of the studs are also at right angles which facilitates attachment to adjoining beams by nails, screws, and other means.
- other configurations such as trusses and rafters, utilize wood beams positioned at various angles relative to one another, depending upon the specific ways the structure is engineered to carry loads or based on the desired slope of a roof.
- a rotatable framing guide includes a base, a rotatable arm, and a lockable retaining pin.
- the base is configured to be secured to two or more surfaces of a first beam, for example adjacent surfaces of the first beam when the distal ends of the base include 90-degree angle flanges.

- Wood beams, or studs can be assembled or preassembled into various configurations to construct the frame of a dwelling, a building, or other structures. Studs can be used to construct trusses, gables, rafters, joists, sill plates, posts, supports, scaffolding, and so forth using different sizes and grades of wood to meet structural requirements.
- Example studs can include two-by-fours, two-by-sixes, two-by-eights, two-by-ten, or bigger studs, as well as four-by-four posts, or larger beams.
- trusses While framing vertical walls is relatively straightforward, framing trusses and floor joists can be substantially more difficult.
- trusses have multiple beams often attached to one another at different angles.
- roof trusses are commonly preassembled, often off-site, and then lifted into position and secured during framing.
- Floor joists present somewhat different challenges.
- Floor joists are designed to support substantially more horizontal weight loading than other structures and are often required to span large distances as well. Because of this, floor joists are generally constructed using larger beams, such as two-by-sixes, and two-by-eights. Because of the additional size and weight of the beams used for floor joists, individual beams are positioned and secured into place during framing.
- a framing guide can provide both accuracy of placement of the beams and facilitate holding beams in position as they are secured in place.
- the rotatable stud framing guide 100 includes a base 102 , a rotatable arm 104 , and a lockable retaining pin comprising a clevis pin 110 , an eccentric cam lever 112 , and a cotter pin 114 .

- the cotter pin 114 is configured to pass through one of the cam apertures 124 , through the clevis aperture 120 , and through the other cam aperture 124 .
- the cotter pin 114 can be any suitable shape and configuration that allows eccentric cam lever 112 to rotate relative to the clevis pin 110 about a long axis of the cotter pin 114 , for example a pin riveted on both ends, a split pin, or an R-clip as would be understood in the art.
- the lockable retaining pin retains the rotatable arm 104 in close proximity to the base 102 while allowing the rotatable arm 104 to rotate relative to the base 102 about the long axis of the clevis pin 110 .
- the eccentric cam lever 112 is rotated so that cams on each of the cam arms 122 press against the base 102 , pulling the clevis pin 110 towards the base 102 .
- the head 116 of the clevis pin 110 is pulled towards the rotatable arm 104 until the head 116 contacts the rotatable arm 104 .
- Further rotation of the eccentric cam lever 112 forces the rotatable arm 104 against the base 102 to secure, through friction, the rotatable arm 104 to the base 102 at a desired angle ⁇ .
- the angle ⁇ of the rotatable arm 104 relative to the base 102 can be defined as being at 0 degrees when the rotatable arm 104 is normal to, or perpendicular to, the base 102 .
- the rotatable arm 104 can rotate along an arc of approximately 120 degrees and the angle ⁇ varies between approximately ⁇ 60 degrees and approximately +60 degrees.
- the arc can be greater than or less than 120 degrees and the range of the arc can be dependent, for example, on mechanical constraints such as the angle ⁇ at which part of the rotatable arm 104 contacts the base 102 which inhibits further rotation.
- the allowable arc of rotation will be less than 180 degrees, however the arc of rotation presented herein is presented as an example only and is not intended to limit all embodiments of the rotatable stud framing guide 100 .
- the base 102 can include a center section 126 that includes an aperture 108 , or hole, and the shaft 118 of the clevis pin 110 is positioned in the aperture 108 to secure the base 102 to the rotatable arm 104 .
- the rotatable arm 104 similarly includes an aperture 108 , or hole, through which the shaft 118 of the clevis pin 110 is positioned.
- the hole in the rotatable arm 104 can be countersunk and the head 116 can be configured to be seated in the countersunk hole of the aperture 108 such that the top of the head 116 is substantially flush with a top surface of the rotatable arm 104 .
- the center section 126 can be recessed or slightly lower than the distal ends of the base 102 such that the top surface of the rotatable arm 104 is substantially flush, or coplanar, with a top surface of the distal ends of the base 102 .
- the base 102 can include angle flanges 128 positioned at the distal ends of the base 102 .
- the angle flanges 128 are nominally at a 90-degree angle ⁇ ′ and configured to abut two adjacent surfaces of a first stud positioned against the base 102 and angle flanges 128 .
- the angle flanges 128 can be suitably sized according to the size of the studs being used.
- the angle flanges 128 can be approximately the same height as the width of the base 102 .
- the height of the angle flanges 128 can be increased to allow multiple attachment points to a stud for additional weight loading capability.
- the height of the angle flanges 128 and the width of the base 102 can be increased to allow attachment to larger posts.
- the rotatable arm 104 can include one or more pairs of opposing compression flanges 130 .
- the compression flanges 130 can be configured such that the angle ⁇ ′′ is less than 90 degrees. In this configuration, when a second stud is placed between the compression flanges 130 , the compression flanges 130 press against opposing surfaces on one end of the second stud to hold the second stud in place. This configuration advantageously helps workers by supporting the weight of the second stud and maintaining the second stud in the desired position while the second stud is being secured permanently in position.
- each of the ends of the compression flanges 130 can include reverse angle flanges 132 angled outwardly from the compression flanges 130 .
- the reverse angle flanges 132 advantageously help workers to insert the second stud between the compression flanges 130 by forcing apart the compression flanges 130 when the second stud is pushed against the reverse angle flanges 132 and the compression flanges 130 .
- the rotatable arm 104 can include any suitable number of compression flanges 130 .
- the rotatable arm 104 can include a single pair of opposing compression flanges 130 , or two or more pairs of opposing compression flanges 130 as illustrated.
- the rotatable arm 104 can include offset or staggered compression flanges 130 or different numbers of compression flanges 130 on each side of the rotatable arm 104 .
- the rotatable arm 104 can include two compression flanges 130 on one side, and a single compression flange 130 on the opposing side. Any suitable arrangement of compression flanges 130 can be used to increase strength, decrease weight or materials costs, or for aesthetic or marketing reasons.
- a plurality of apertures 106 allow workers to permanently secure the first stud and second stud to the rotatable stud framing guide 100 using fasteners 134 such as wood screws, bolts and nuts, nails, or other suitable fasteners.
- the base 102 , the angle flanges 128 , the rotatable arm 104 , and the compression flanges 130 can all include apertures 106 .
- the apertures 106 can be offset from one another so that the fasteners 134 do not intersect with other fasteners 134 when inserted into the studs. For example, if bolts are used as the fasteners 134 , then holes in the base 102 and angle flanges 128 may need to be offset from another.
- holes can be aligned in opposing compression flanges 130 to allow a single bolt to pass through the stud and both of the compression flanges 130 .
- Any suitable configuration of offset apertures 106 or aligned apertures 106 can be used as would be understood in the art.
- FIG. 2 a front view of the rotatable stud framing guide 100 of FIG. 1 is presented including the base 102 , center section 126 , angle flanges 128 , rotatable arm 104 , compression flanges 130 , reverse angle flanges 132 , apertures 106 , and the assembled lockable retaining pin 200 .
- the assembled lockable retaining pin 200 functions as a rotatable locking mechanism to selectively secure the rotatable arm 104 to the base 102 at the desired angle. In this view, the assembled lockable retaining pin 200 is in the locked position.

- the cam arm 122 of the eccentric cam lever 112 has a longer radius r′ near the flat edge 302 of the eccentric cam lever 112 , and a shorter radius r for other portions of the cam arm 122 that decreases as one moves further away from the flat edge 302 .
- the eccentric cam lever 112 When the eccentric cam lever 112 is in the locked position, the eccentric cam lever 112 is configured so that the flat edge 302 is substantially flush with the bottom surface of the base 102 .
- having the flat edge 302 flush against the base 102 substantially reduces the likelihood that the eccentric cam lever 112 could be accidentally struck and forced into the unlocked position which would allow the rotatable arm 104 to rotate unexpectedly.

Abstract
Description
- This application is a continuation-in-part of U.S. Design application Serial No. 29/618,406 filed Sep. 21, 2017 which is herein incorporated by reference in its entirety. This application is related to U.S. Design application Serial No. 29/634,743 filed Jan. 24, 2018.
- This application relates generally to a framing guide for use in construction. The application relates more particularly to a guide for positioning studs for framing dwellings and buildings.
- Modern construction practices utilize wood beams, or studs, that are assembled or preassembled into various configurations to construct the frame of a dwelling or a building. Framing configurations can include structures such as trusses, gables, rafters, joists, sill plates, posts, supports, scaffolding, and so forth. Different sizes and grades of wood can be used depending on the structural necessities of the particular part of a structure being framed. For example, studs such as two-by-fours are commonly used to frame wall sections where the forces are generally vertical, while two-by-six or bigger studs are common for floor joists which have to support substantial horizontal forces as well.
- Some configurations utilize wood beams placed at right angles to one another. For example studs used to frame wall sections are generally in horizontal and vertical orientations. These configurations tend to be relatively easy to position and secure to one another as the various surfaces of the studs are also at right angles which facilitates attachment to adjoining beams by nails, screws, and other means. However, other configurations such as trusses and rafters, utilize wood beams positioned at various angles relative to one another, depending upon the specific ways the structure is engineered to carry loads or based on the desired slope of a roof.
- In accordance with an example embodiment of the subject application, a rotatable framing guide includes a base, a rotatable arm, and a lockable retaining pin. The base is configured to be secured to two or more surfaces of a first beam, for example adjacent surfaces of the first beam when the distal ends of the base include 90-degree angle flanges. The rotatable arm is configured to be secured to two or more surfaces at the end of a second beam, for example opposing surfaces of the second beam when the rotatable arm include one or more pairs of compression flanges. The lockable retaining pin is configured to keep the rotatable arm in close proximity to the base, provide an axis of rotation when in an unlocked configuration, and lock the rotatable arm to the base when in a locked configuration. The lockable retaining pin can include a clevis pin, an eccentric cam lever, and a cotter pin configured to secure the eccentric cam lever to the clevis pin. The clevis pin can include am aperture configured to receive the cotter pin, a shaft that configured to pass through the apertures in the base and the rotatable arm, and a head at the top of the shaft that has a larger diameter than the aperture in the rotatable arm and that works in conjunction with the eccentric cam lever to secure the rotatable arm to the base.
- In accordance with an example embodiment of the subject application, a framing guide for aligning a first beam with a second beam includes a base, a rotatable arm, and a locking retaining pin. The base includes a center pivot hole and a pair of 90-degree angle flanges at each end. The rotatable arm includes a pivot hole at one end and a set of opposing compression flanges at the other end. The base and rotatable arm are configured to be secured to the first and second beams respectively. The lockable retaining pin secures the rotatable arm to the base, allows rotation of the rotatable arm relative to the base, and selectively locks the rotatable arm at a desired angle relative to the base so as to align the second beam with the first beam.
- In accordance with an example embodiment of the subject application, a stud framing guide includes a guide body, and a guide arm extending perpendicularly from the guide body. The guide body includes a two or more angle flanges. Holes in the guide body and angle flanges allow the guide body to be secured along the length of a first stud using suitable fasteners. The guide arm includes two or more opposing flanges configured to hold an end of the second stud in the guide arm. Holes in the guide arm and opposing flanges allow the guide arm to be secured to the end of the second stud using suitable fasteners.
- Various embodiments will become better understood with regard to the following description, appended claims and accompanying drawings wherein:

It will be appreciated that modifications to disclosed and described examples, arrangements, configurations, components, elements, apparatuses, devices methods, systems, etc. can suitably be made and may be desired for a specific application. In this disclosure, any identification of specific techniques, arrangements, etc. are either related to a specific example presented or are merely a general description of such a technique, arrangement, etc. Identifications of specific details or examples are not intended to be, and should not be, construed as mandatory or limiting unless specifically designated as such.
- Wood beams, or studs, can be assembled or preassembled into various configurations to construct the frame of a dwelling, a building, or other structures. Studs can be used to construct trusses, gables, rafters, joists, sill plates, posts, supports, scaffolding, and so forth using different sizes and grades of wood to meet structural requirements. Example studs can include two-by-fours, two-by-sixes, two-by-eights, two-by-ten, or bigger studs, as well as four-by-four posts, or larger beams.
- While framing vertical walls is relatively straightforward, framing trusses and floor joists can be substantially more difficult. For example, trusses have multiple beams often attached to one another at different angles. For consistency, roof trusses are commonly preassembled, often off-site, and then lifted into position and secured during framing. Floor joists present somewhat different challenges. Floor joists are designed to support substantially more horizontal weight loading than other structures and are often required to span large distances as well. Because of this, floor joists are generally constructed using larger beams, such as two-by-sixes, and two-by-eights. Because of the additional size and weight of the beams used for floor joists, individual beams are positioned and secured into place during framing.
- However, precise positioning of individual beams and holding beams in place while securing them during construction can be both difficult and labor intensive. A framing guide can provide both accuracy of placement of the beams and facilitate holding beams in position as they are secured in place.

Thecotter pin 114 can be any suitable shape and configuration that allowseccentric cam lever 112 to rotate relative to theclevis pin 110 about a long axis of thecotter pin 114, for example a pin riveted on both ends, a split pin, or an R-clip as would be understood in the art. - In an unlocked configuration, the lockable retaining pin retains the
rotatable arm 104 in close proximity to the base 102 while allowing therotatable arm 104 to rotate relative to the base 102 about the long axis of theclevis pin 110. In a locked configuration, theeccentric cam lever 112 is rotated so that cams on each of thecam arms 122 press against thebase 102, pulling theclevis pin 110 towards thebase 102. As theeccentric cam lever 112 is rotated, thehead 116 of theclevis pin 110 is pulled towards therotatable arm 104 until thehead 116 contacts therotatable arm 104. Further rotation of theeccentric cam lever 112 forces therotatable arm 104 against the base 102 to secure, through friction, therotatable arm 104 to the base 102 at a desired angle θ. - In a non-limiting example, the angle θ of the
rotatable arm 104 relative to the base 102 can be defined as being at 0 degrees when therotatable arm 104 is normal to, or perpendicular to, thebase 102. In this example therotatable arm 104 can rotate along an arc of approximately 120 degrees and the angle θ varies between approximately −60 degrees and approximately +60 degrees. In other configurations the arc can be greater than or less than 120 degrees and the range of the arc can be dependent, for example, on mechanical constraints such as the angle θ at which part of therotatable arm 104 contacts the base 102 which inhibits further rotation. Generally, the allowable arc of rotation will be less than 180 degrees, however the arc of rotation presented herein is presented as an example only and is not intended to limit all embodiments of the rotatablestud framing guide 100. - The base 102 can include a
center section 126 that includes anaperture 108, or hole, and theshaft 118 of theclevis pin 110 is positioned in theaperture 108 to secure the base 102 to therotatable arm 104. Therotatable arm 104 similarly includes anaperture 108, or hole, through which theshaft 118 of theclevis pin 110 is positioned. The hole in therotatable arm 104 can be countersunk and thehead 116 can be configured to be seated in the countersunk hole of theaperture 108 such that the top of thehead 116 is substantially flush with a top surface of therotatable arm 104. Thecenter section 126 can be recessed or slightly lower than the distal ends of the base 102 such that the top surface of therotatable arm 104 is substantially flush, or coplanar, with a top surface of the distal ends of thebase 102. - The base 102 can include
angle flanges 128 positioned at the distal ends of thebase 102. The angle flanges 128 are nominally at a 90-degree angle θ′ and configured to abut two adjacent surfaces of a first stud positioned against thebase 102 andangle flanges 128. In a configuration, theangle flanges 128 can be suitably sized according to the size of the studs being used. For example, theangle flanges 128 can be approximately the same height as the width of thebase 102. In another example, for larger floor joists the height of theangle flanges 128 can be increased to allow multiple attachment points to a stud for additional weight loading capability. In yet another example, the height of theangle flanges 128 and the width of the base 102 can be increased to allow attachment to larger posts. - The
rotatable arm 104 can include one or more pairs of opposingcompression flanges 130. Thecompression flanges 130 can be configured such that the angle θ″ is less than 90 degrees. In this configuration, when a second stud is placed between thecompression flanges 130, thecompression flanges 130 press against opposing surfaces on one end of the second stud to hold the second stud in place. This configuration advantageously helps workers by supporting the weight of the second stud and maintaining the second stud in the desired position while the second stud is being secured permanently in position. In this configuration, each of the ends of thecompression flanges 130 can includereverse angle flanges 132 angled outwardly from thecompression flanges 130. Thereverse angle flanges 132 advantageously help workers to insert the second stud between thecompression flanges 130 by forcing apart thecompression flanges 130 when the second stud is pushed against thereverse angle flanges 132 and thecompression flanges 130. - In various configurations, the
rotatable arm 104 can include any suitable number ofcompression flanges 130. For example, therotatable arm 104 can include a single pair of opposingcompression flanges 130, or two or more pairs of opposingcompression flanges 130 as illustrated. In yet another example, therotatable arm 104 can include offset or staggeredcompression flanges 130 or different numbers ofcompression flanges 130 on each side of therotatable arm 104. For example, in one configuration therotatable arm 104 can include twocompression flanges 130 on one side, and asingle compression flange 130 on the opposing side. Any suitable arrangement ofcompression flanges 130 can be used to increase strength, decrease weight or materials costs, or for aesthetic or marketing reasons. - A plurality of
apertures 106, or holes, allow workers to permanently secure the first stud and second stud to the rotatablestud framing guide 100 usingfasteners 134 such as wood screws, bolts and nuts, nails, or other suitable fasteners. Thebase 102, theangle flanges 128, therotatable arm 104, and thecompression flanges 130 can all includeapertures 106. In an embodiment, theapertures 106 can be offset from one another so that thefasteners 134 do not intersect withother fasteners 134 when inserted into the studs. For example, if bolts are used as thefasteners 134, then holes in thebase 102 andangle flanges 128 may need to be offset from another. In another example, if bolts are used as thefasteners 134, then holes can be aligned in opposingcompression flanges 130 to allow a single bolt to pass through the stud and both of thecompression flanges 130. Any suitable configuration of offsetapertures 106 or alignedapertures 106 can be used as would be understood in the art. - Referring to
FIG. 2 , a front view of the rotatablestud framing guide 100 ofFIG. 1 is presented including thebase 102,center section 126,angle flanges 128,rotatable arm 104,compression flanges 130,reverse angle flanges 132,apertures 106, and the assembled lockable retainingpin 200. The assembled lockable retainingpin 200 functions as a rotatable locking mechanism to selectively secure therotatable arm 104 to the base 102 at the desired angle. In this view, the assembled lockable retainingpin 200 is in the locked position. - Referring to
FIG. 3 , a close upview 300 of the rotatable locking mechanism of the rotatable stud framing guide ofFIG. 2 is presented. Portions of the assembled lockable retainingpin 200 are illustrated including theclevis pin 110, theeccentric cam lever 112, and thecotter pin 114 which has been inserted through acam aperture 124 of theeccentric cam lever 112. Thecam arm 122 of theeccentric cam lever 112 has a longer radius r′ near theflat edge 302 of theeccentric cam lever 112, and a shorter radius r for other portions of thecam arm 122 that decreases as one moves further away from theflat edge 302. When theeccentric cam lever 112 is in the locked position, theeccentric cam lever 112 is configured so that theflat edge 302 is substantially flush with the bottom surface of thebase 102. Advantageously, wheneccentric cam lever 112 is in the locked configuration, having theflat edge 302 flush against the base 102 substantially reduces the likelihood that theeccentric cam lever 112 could be accidentally struck and forced into the unlocked position which would allow therotatable arm 104 to rotate unexpectedly. - Referring to
FIG. 4 , acutaway view 400 of the rotatable locking mechanism of the rotatable stud framing guide ofFIG. 3 is presented. Portions of the assembled lockable retainingpin 200 are illustrated including theclevis pin 110, theeccentric cam lever 112, and thecotter pin 114 which has been inserted through theclevis aperture 120 of theeccentric cam lever 112. Theshaft 118 of theclevis pin 110 passes through the lockingaperture 108 of therotatable arm 104 andbase 102. Theclevis pin 110 includes a taperedhead 116 that seats flush against a taperedportion 402 of the lockingaperture 108 of therotatable arm 104. - Referring to
FIG. 5 , a close upview 500 of the rotatable locking mechanism of the rotatable stud framing guide ofFIG. 2 is presented. In thisview 500, theeccentric cam lever 112 is in the unlocked position. In this configuration, thecam arm 122 of theeccentric cam lever 112 nearest to the base has a shorter radius r than the radius r′ near the flat edge of theeccentric cam lever 112. As a result of the shorter radius r, theeccentric cam lever 112 does not exert force against thebase 102 and therotatable arm 104 is free to rotate relative to thebase 102. Advantageously, when theeccentric cam lever 112 is in the unlocked configuration, theeccentric cam lever 112 is easily accessible by a worker for rotation into the locked configuration. - Referring to
FIG. 6 , abottom perspective view 600 of the rotatable stud framing guide ofFIG. 1 is presented. In this view, thelockable retaining pin 200 is in a locked configuration and therotatable arm 104 is secured against thebase 102. - Referring to
FIG. 7 , abottom view 700 of the rotatable stud framing guide ofFIG. 1 is presented. In thisbottom view 700, therotatable arm 104 is locked at an angle θ to thebase 102. - Referring to
FIG. 8 , an explodedview 800 of the rotatable stud framing guide ofFIG. 1 is presented. In this explodedview 800, the taperedportion 402 of the lockingaperture 108 of therotatable arm 104 is visible. To assemble the rotatable stud framing guide, theclevis pin 110 is inserted through both lockingapertures 108 of therotatable arm 104 andbase 102, and acotter pin 114 is inserted through theeccentric cam lever 112 andclevis pin 110. - Referring to
FIG. 9 a perspective view of astud framing guide 900 is presented. Thestud framing guide 900 includes aguide body 902 and aguide arm 904 connected to the center of theguide body 902. Theguide body 902 includes two angle flanges at the distal ends of the guide body rotated at right angles, or 90-degrees, relative to the guide body. Theguide body 902 and angle flanges are configured to abut adjoining surfaces of a first stud. Theguide arm 904 includes one or more pairs of compression flanges. The top of each compression flange can include a reverse angle flanges to assist a worker with inserting the end of a second stud between the compression flanges into theguide arm 904. Fasteners, such as wood screws, can be inserted through apertures in theguide body 902,guide arm 904, angle flanges, and compression flanges into the studs to permanently secure the studs to thestud framing guide 900.Viewing apertures 908 can assist a worker with alignment of thestud framing guide 900 and the studs. Theviewing apertures 908 can be used to apply marks to the studs. - The
stud framing guide 900 can be constructed from a single flat piece of metal of suitable thickness by first cutting the metal into the appropriate shape and then bending portions of the metal to make the angle flanges, compression flanges, and reverse angle flanges. Theapertures 906 andviewing apertures 908 can be drilled or milled prior to bending the portions of the metal into shape. -
