Furthermore, the large profile and the contours 309 of the fastener 307 facilitate holding and positioning by an individual using their fingers prior to it being tapped into place with a hammer. Conversely, smaller type nails are hard to hold along a narrow one to two inch width of a stud, especially when it is installed tight against a perpendicular surface such as a wall.
- the fasteners 307 are also designed to be reusable.
- the fastener 307 of FIG. 17 shows the addition of a hole 311 through the fastener body for the option of holding it in place with a nail or screw, if desired.

An embodiment of the disclosed bracket may be attached between two boards to permit better access to the locking mechanism. A reusable fastener is also disclosed.
Description
- The present application is a continuation-in-part of U.S. patent application Ser. No. 13/488,041 titled “Expandable Stud Bracket” and filed on Jun. 4, 2012. This application also claims the filing priority of U.S. Provisional Application No. 61/960,004, filed Sep. 9, 2013, and titled “Options And Accessories To An Expandable Bracket For Temporary 2×4 Installation.” The entirety of the '004 provisional application is hereby incorporated by reference.
- The present device and system relate to building materials for erecting temporary walls. Particularly, the present device and system relate to an expandable bracket to facilitate construction of a temporary wall or work-space.
- In the construction field, the need for installation of temporary walls and studs (vertical and horizontal) often arises. Some of these occurrences are expected and some unexpected. Regardless, erecting these temporary structures can add considerable cost and time to a construction project. The frequency of the need for such structures appears to be on the increase.
- For example, as a result of new Federal construction laws, dust control walls are now required under certain circumstances. Specifically, a contractor/remodeler must contain and isolate any area where lead-base paint may be present prior to cutting and removing walls or ceiling material from the structure. This law applies to any home, school, or day care facility built before 1978, where the presence of lead-based paint must be assumed and tested for before work can be performed.
- Similarly, some construction projects require the installation of temporary studs. When an existing wall is being prepared to be removed, the ceiling structure above must be temporarily supported. This is commonly accomplished by installing a temporary 2″×4″ stud under each ceiling support joist. When done properly, installation of the temporary wall can require as much time and energy as construction of a permanent wall.
- The systems that are currently available are designed solely to support the weight of plastic for dust control. These systems are not designed to support the weight that would be required for a temporary support structure. Many of these dust control systems consist of round metal telescoping poles which are designed to hold the plastic at the ceiling. Adhering the plastic to the round pole is cumbersome and expensive when using additional material such as painter's tape.

- Referring to
FIGS. 1-11 , there is illustrated several embodiments of an expandable bracket, generally designated by thenumeral 10. Additional embodiments and related components are similarly designated with the addition of a 1, 2, 3, . . . etc. to distinguish between such embodiments. Thebracket 10 can be designed for attachment to an end of a 2″×4″, 4″×4″, or 2″×6″ board, then the assembly is placed between two stationary surfaces, e.g., floor-to-ceiling, wall-to-wall, and expanded. The assembly may be used both horizontally and vertically with equal success and is not limited to the few examples described and illustrated herein. - In the embodiment illustrated in
FIGS. 1-6 , thebracket 10 includes ahousing 12 comprised ofsidewalls 14, atop panel 15, and front and back panels 16 a-b, and an expansion mechanism 18 (Note: theback panel 16 b is shown in broken lines inFIG. 1 to allow better viewing of the bracket interior). The bottom of thehousing 12 is left open for receiving the end of a board.Holes 13 defined within the sidewalls, and top, front and back panels allow nails and/or screws (not shown) to retain the board within the open end of thebracket 10. Aninternal stop 20 is used to halt the insertion of the board so as not to interfere with the operation of theexpansion mechanism 18. Window 11 (FIG. 2 ) is preferably defined within the front panel 16 a to allow the user to visually ascertain when a board is inserted sufficiently to contactstop 20. - Referring to
FIG. 3 , theexpansion mechanism 18 is positioned at the top of thebracket 10 and includes anengagement plate 21, an extension rod, and ananchor 24. Theengagement plate 21 is preferably fixed, via a weld or other means, to one end of theextension rod 22, while theanchor 24 is likewise fixed to the other end of therod 22. In various of the disclosed embodiments, theengagement plate 21 and/or theanchor 24 may include holes for securing to a surface via nails or screws.FIG. 6 illustrates edge slots onengagement plate 21 for “toe-nailing” to a surface. - An opening in the
top panel 15 and aguide 25 positioned within thehousing 12, retain theextension rod 22 in a position to move only in a direction perpendicular to thetop panel 15. Theguide 25 is preferably provided by cutting three sides of a rectangular section of the front panel 16 a and bending it into the housing interior, leaving anopening 17 on the front panel 16 a ofhousing 12. Theguide 25, which is completed with a hole therein to retain theextension rod 22, also provides a limit to the upward movement of therod 22 by stopping theanchor 24 from further travel. Therod 22 otherwise moves freely within the holes of thetop panel 15 andguide 25. - Preferably, the
expansion mechanism 18 provides about 0.5 inches to about 6 inches of adjustability. Most preferably, the adjustability is limited to a range of from about 0.75 inches to about 2.0 inches. In a preferred embodiment, shown inFIGS. 4 a-b, theexpansion mechanism 18 is extended manually through opening 17 in front panel 16 a. Theanchor 24 is provided with atab 45 which extends through theopening 17 and aprotective cover 46 which prevents the user from placing anything, especially fingers, under theanchor 24. As theanchor 24 is raised viatab 45, theprotective cover 46 blocks theopening 17. This is not only an important safety feature for the illustrated embodiment, but a useful feature for more readily extending theengagement plate 21. Thetab 45 allows a user to use one hand to raise and hold theplate 21 in place, while adjustinglocking mechanism 26 with the other hand. - Also shown in
FIGS. 1-3 is lockingmechanism 26 attached to therod 22 to lock the downward travel of therod 22, and thus theengagement plate 21. For ease of access and structural integrity, thelocking mechanism 26 is positioned outside thebracket housing 12 to abut thetop panel 15 in use. However, it may be alternately positioned within thehousing 12 to abut theguide 25 or another surface. In the illustrated embodiment, therod 22 is a threaded rod and thelocking mechanism 26 is aknurled finger nut 30 threaded onto therod 22. - The
nut 30 is also preferably provided withlever slots 31 to facilitate tightening of thelocking mechanism 26. Theslots 31 are merely round openings into which a tool may be inserted for added leverage totorque nut 30 to be either tightened or loosened onrod 22. Specifically for this purpose, alever 32 may be provided as part of a stud expansion system. Thelever 32 is preferably metal and round (in cross-section) with a length sufficient to allow turning of thenut 30 without impacting the user's hands (e.g., knuckles) on thehousing 12 edges. Thelever 32 may also be stored on or within thehousing 12 using by adding a slot (not shown) or magnets (not shown). - As an optional feature of the
bracket system 10, adetachable foot 34 may be provided. Thefoot 34 is preferably a U-shaped device having nail/screw holes defined therein. Arubber pad 35 may also be provided on a contacting surface of thefoot 34. Thefoot 34 may be used in one of two ways. - The
foot 34 may be secured to an opposite end of a board within thebracket 10. This allows the padded side of thefoot 34 to contact other surfaces without marring, scratching or moving. Alternatively, thefoot 34 may be inverted and secured by nail/screw to the opposite end of the board within thebracket 10, via the padded surface, and also secured by nail/screw to a perpendicular board via the arms of thefoot 34. The latter configuration is preferably used whenever the support board is being attached to a perpendicular board. Anotch 37 may optionally be provided in thefoot 34, as shown inFIG. 5 a, to allow storage during non-use. - In use, with reference to
FIG. 2 , an end of a board of the proper dimensions is first secured within the receiving end of thebracket 10 using the defined sidewall holes and nails or screws. Similarly, thefoot 34 may be optionally attached to the opposite end of the board, as described above. Theexpansion mechanism 18 is then manually extended to a distance just less than the span in which the temporary stud is to be placed. This is done by extending out theengagement plate 21 by lifting theanchor 24. Thenut 30 is then easily spun to engage thetop panel 15 ofhousing 12. - The assembly can then be positioned properly in the desired space and the
lever 32 can be inserted into aslot 31 and used to turn thelocking mechanism 26 to thereby further extend theextension rod 22 andengagement plate 21 until sufficient support is achieved. At all times while turning thelocking mechanism 26/nut 30, theanchor 24 prevents turning of the threaded rod by contacting thehousing 12. - If necessary, to remove or reposition the temporary stud assembly, the
lever 32 may be inserted into aslot 31 and used to turn thelocking mechanism 26 in an opposite direction until contact between theengagement plate 21 and opposing surface is lost. The assembly may then be repositioned and retightened or disassembled and stored. - Referring to
FIGS. 6-8 , several features of alternate embodiments of the present invention,bracket system 110, are illustrated. In these embodiment, thehousing 112 is open on both ends to receive a board in one end and theexpansion mechanism 118 in the other. Here theexpansion mechanism 118 is manufactured as a separate component from thehousing 112 and attaches to thehousing 112 viatabs 140 inserted within slots 141. This configuration may be best utilized where a less expensive plastic moldedhousing 118 is used, for example. - Similar to previous embodiments, the
expansion mechanism 118 ofFIG. 6 comprises anengagement plate 121, anexpansion rod 122, and ananchor plate 124, but also includes anexpansion tube 125 fixed to theanchor plate 124. Theattachable expansion mechanism 118 may be positioned within thehousing 112 by snap-fitting thetabs 140 within slots 141, where they may not be removed without destroyinghousing 112. Theanchor plate 124 rests onstop 120 for further support. As with the previous embodiment described above, therod 122 may be manually extended and thelocking mechanism 126 tightened to prevent inward movement of therod 22. Theexpansion tube 125 is preferably keyed to theexpansion rod 122 or otherwise configured to prevent turning of theexpansion rod 122 when engaginglocking mechanism 126. - Alternatively, the
tube 125 may include internal threads to engage the threadedexpansion rod 122. Theengagement plate 121 androd 122 would require turning to extend the mechanism to a desired length. No locking mechanism would be required. - In either configuration, the
anchor plate 124 includes holes therein for insertion of nails or screws for attachment to a board inserted in the opposite end ofhousing 112. As shown inFIG. 8 , a possible alternate use for the illustrated embodiment may include attachment of themechanism 118 to a board end and insertion of boards into both ends of thehousing 112. - Optionally, a
detachable foot 134 may also be provided. By providingstorage slots 142 onhousing 112, the arms offoot 134 may be inserted into theslots 142 for storage of the foot during non-use. Magnets fixed to thebracket housing 112 may be used to provide a more positive retention of the storedmetal foot 134. - In use, the
bracket system 110 ofFIG. 8 may allow a greater span for installation by using a board inserted at both ends of thehousing 112. Theexpansion mechanism 118 attaches by theanchor plate 124 to a free end of one of the boards, while the optional foot attaches to a free end of the other board. Theexpansion mechanism 118 is extended to a distance slightly less than the necessary distance and then positioned where needed. Theengagement plate 121 can then be further extended to contact and sufficiently support the opposing surface by either turning thelocking mechanism 126 or theengagement plate 121, as required. -
FIG. 7 illustrates asleeve 102 which provides a user with the ability of using, for example, two 4 ft boards (or some variation of two boards measuring 8 ft total) instead of one 8 ft board.Window 117 provides visual assurance of the two boards proper seating insleeve 102. Either of the free ends of the two boards may then be used with thebracket system 10/110 as described above. -
FIGS. 9-11 illustrate still another embodiment of the invention,bracket system 210. Thisbracket 210 is suitable for use on flat and sloped surfaces, such as a vaulted ceiling. Thebracket 210 is comprised of housing 212 andbase 221. The housing 212 includes a receiving end for attachment to a board viabolt 250 andwing nut 251 positioned within slot 232. The slot 232 allows the attached board to move a distance and pivot within thehousing 12. Thebase 221 includes complementary wedges, specificallystationary wedge portion 260 having an approximately 45° surface and amovable wedge portion 262 also having an approximately 45° surface—the individual angles may vary, so long as the resulting combined angle of the two wedges is at least 90°. Themovable wedge 262 is configured to slide along thestationary wedge 260 to adjust the angle of the secured board relative thebase 221. A dovetail connector is illustrated inFIG. 9 , while achannel 263 and bolt 264 connection is shown inFIG. 10 . Numerous alternate connection configurations are possible. - In use, a board is inserted into the open end of
housing 12 and secured withbolt 250 andwing nut 251—a hole may need to be drilled first. The assembly is positioned where needed with thebase surface 221 facing the surface to be supported. The position of board inhousing 12 may be adjusted by loosening and retightening thebolt 250 andwing nut 251. Themovable wedge 262 can then we slid betweenstationary wedge 260 and the end of the board until a desired angle within the range of from about 10 to about 90 degrees is achieved. As shown inFIG. 11 , thebase 221 may include a screw hole for securing the base 221 to the surface before setting thebolt 250 andwing nut 251. -
FIG. 11 illustrates a double-hook 263 attached to thebase 221. Where a plurality of supports need to be constructed, astring line 266 may be run between twobrackets 210, as is known in the art, to align a series ofbases 221. As previously described, thebases 221 may be attached via the screw hole before insertion of a board - Referring now to
FIGS. 12-17 , additional embodiments and accessories to theexpandable bracket 10 are shown. - Under certain conditions a 2″×4″ board used along with an embodiment of the
expandable bracket 10 may shrink slightly during use, especially in dry conditions when the system is in place over a long period of time. The following improvement will help compensate for the potential shrinkage. - In an embodiment, the shrinkage is compensated by spring loading elements of the
bracket 10 so they “self-adjust” under a release of tension (which would occur from shrinkage).Location 300, under thenut 26 of thetreaded rod 22, is one example where spring-loading can be useful. The type of spring used may vary, including a common coil spring (not shown) or a Belleville washer (or spring washer) 301, as shown inFIG. 13 . In the case of the Belleville washer 301, one or more may be used, with additional washers being stacked as is well-known in the art (i.e., front to front and back to back) on the threadedrod 22. This type of arrangement creates space for the cupped washers to collapse under a load and then regain their cupped shape after the load is relieved. The varied tension created and maintained by the spring washer(s) may occur either in response to shrinkage or when thebracket nut 26 is loosened for removal. Alternatively or additionally, other areas of thebracket 10 may be spring loaded, such as under the top plate or inside the main housing at positions 302 (FIG. 12 ) where the stud slides into thebracket 10. - Another embodiment of the
bracket 10 may be used between two shorter 2″×4″ studs, as shown inFIG. 14 , as opposed to being at the top or bottom of the stud, as previously disclosed. This embodiment is similar to that shown inFIG. 7 which shows a sleeve for connecting two lengths of 2″×4″ boards.Arrows 304 illustrate where the 2″×4″ would be inserted and fastened in place with screws, nails, etc. through holes 13.Arrow 305 shows the direction of travel the two housings are allowed to move in. The two housings would be connected byguides 306 which are comprised of slots on one housing and a pin in the other to keep the two housing brackets aligned. These guides and/or slots may be various sizes and may also be located on the narrow or wide side of the brackets. - Referring to
FIG. 15 , by positioning the adjustment mechanism of the system within the reach of a user, it would allow the tightening and loosening in place without the need for a ladder. Padded ends (seeFIG. 5A ,components 21 and 34) could still be attached at the top and the bottom of the stud, as previously disclosed. -
FIGS. 16 and 17 show two embodiments of areusable fastener 307 for holding sheet-like materials such as plastic, cloth, Tyvek, etc. in place over a 2×4 framework created using the disclosedexpandable bracket 10. The pointed ends 310 of thefastener 307 are easily driven into a wood substrate, such as a stud.FIG. 16 also illustrates a typical wood framework where these fasteners would be used along its length. The temporary installation of such materials is necessary when theexpandable bracket 10 is being used for dust control or containment or to visually separate two spaces. Current means for holding these materials in place are staples, nails, screws, etc. When a standard staple is used, it may be difficult to remove and/or it may even tear through a plastic sheet. Nails into wood are also hard to remove. Screws may also pull through the sheet material or may twist a fabric type sheet. - The
fastener 307 ofFIG. 16 will not only hold the material in place but is also designed to be removed easily with a flat screw driver, pry bar, or the like, placed within one of theopenings 308 to pry against. Furthermore, the large profile and thecontours 309 of thefastener 307 facilitate holding and positioning by an individual using their fingers prior to it being tapped into place with a hammer. Conversely, smaller type nails are hard to hold along a narrow one to two inch width of a stud, especially when it is installed tight against a perpendicular surface such as a wall. Thefasteners 307 are also designed to be reusable. - The
fastener 307 ofFIG. 17 shows the addition of ahole 311 through the fastener body for the option of holding it in place with a nail or screw, if desired. - The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants' contribution. Specifically, several of the disclosed features of the present invention are described and illustrated with some embodiments and not others. Such examples are intended to be descriptive of the features and not limiting of the possible embodiments. It should be understood that all the disclosed features may be provided in any of the described embodiments, as desired. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
