This is related to, and claims the benefit under 35 USC §119(e) of U.S. Provisional Application for Patent No. 60/824,652, which was filed on Sep. 6, 2006.
FIELD OF THE INVENTIONThe present invention relates in general to metal wall frames, and in particular to such frames which include channels and studs having integrally formed connectors, locators, and retainers.
BACKGROUND OF THE INVENTIONFraming systems have been developed using metal channels and studs in place of more conventional wood frames. Such systems have been adapted to construct various structures including residential and commercial buildings, and particularly the partitions of such buildings. Although these systems function adequately, they are sometimes difficult to use and can take longer to assemble than can conventional wood frames.
Because of these drawbacks, many builders have been reluctant to adopt conventional metal framing systems. Moreover, installers have experienced difficulty in correctly installing some conventional metal framing systems. Installers also dislike the snipping and cutting of the metal frame members required in such systems, as the sharp metal edges can result in cut hands and torn clothes. For these reasons, wood frames are still commonly used for residential construction.
Although wood frames have been widely accepted by builders and installers, wood frames are not fireproof and wood tends to buckle, warp, split, shrink, and bend out of shape. Moreover, a wood stud is heavier and more awkward to work with than a metal stud, and is currently about twice the price of a metal stud.
Even with the drawbacks associated with wood frames, wood is still the material of choice of most builders, particularly since carpenters are familiar with wood frame construction and can nail wood frames together with a nail gun faster than they can screw a fastener into a metal frame with a screw gun.
The following comparison of existing standard wood and conventional metal stud applications might be of value in fully appreciating the advantages of the present invention.
Installation of a wall partition constructed of wooden studs, after upper and lower plates have been installed, requires the following steps for each stud:
-
- 1. Measure 16 inches on center or 24 inches on center from the previously-installed stud and appropriately mark the measured distance on the upper and lower plate.
- 2. Measure the distance between upper and lower plates.
- 3. Measure the length of the stud to be installed to be equal to the measurement in the previous step and mark the stud where it is to be cut.
- 4. Cut the stud. The cut must be cut square, using a miter box, skill saw guide, etc.
- 5. Place the stud into position between the plates. Adjust the position of the stud by applying a level to assure that it is plumb, top to bottom, side to side and front to back.
- 6. Nail the bottom portion of the stud to the lower plate using two nails, either manually or with a nailing gun.
- 7. Climb a ladder or scaffold and nail the top portion of the stud to the upper plate, again using two nails.
- 8. Usually framers will also install horizontal wood members to serve as braces and spacers between the studs. In such case there are the following additional steps:
- A. Measure and mark a piece of stud lumber to fit between the studs.
- B. Cut the piece of lumber square to form a brace.
- C. Nail two nails to one end of the brace and into one stud.
- D. Nail two nails into the other end of the brace and into the other stud.
- 9. When electricians run electrical cable through the studs, it is necessary for them to first bore a hole through each stud individually, that is, through those studs that will have cable going through them.
It is apparent that wood fame construction requires many individual time-consuming steps. Moreover, problems associated with wood studs include:
-
- 1. Wood is not fireproof.
- 2. Wood can buckle, split, shrink, and bend out of shape.
- 3. A wood stud is heavier and clumsier to work with than a corresponding metal stud.
- 4. A wood stud is currently about double the price of a metal stud, and with continuing depletion of natural reserves, prices for lumber will likely continue to rise.
Installation of a partition constructed of conventional metal studs, after the upper and lower channels have been installed, requires the following steps for each stud:
-
- 1. Measure 16 inches on center or 24 inches on center from a previously-installed stud and appropriately mark the measured distance on the upper and lower channels.
- 2. Measure the distance between upper and lower channels.
- 3. Measure the length of the stud to be installed to be equal to the measurement in the previous step and mark the stud where it is to be cut.
- 4. Cut the two side flanges of the stud with a pair of snippers, and then bend the central backbone of the stud back and forth until it breaks off.
- 5. Place the stud into position between the channels where previously marked. Adjust the position of the stud by applying a level to assure that it is plumb, top to bottom and side to side.
- 6. Take two screws and individually mount each screw onto a screw gun and screw the bottom portion of the stud into the lower channel.
- 7. Climb a ladder, and again, take two screws and individually mount each onto a screw gun and screw the upper portion of the stud into the upper channel.
- 8. Many installers also place a horizontal brace and spacing member that runs through the apertures of several studs. In such case, there are the following additional steps:
- A. Run the bracing member through the apertures of several studs.
- B. Cut little tabs to connect and fasten each stud to its section of bracing member.
- C. Line up each stud to be properly aligned and plumb with each corresponding section of bracing member.
- D. Screw into a precut tab to connect the stud to the bracing member.
It can be seen that conventional metal frame construction requires many individual time-consuming steps. Moreover, problems associated with conventional metal studs include:
-
- 1. There does not seem to be any installation time savings of metal over wood. In fact, one can argue that a wooden frame will go up faster than a metal frame because of the extra time required with metal in the process of cutting the stud to size and the fumbling required with screws as opposed to automatic nailing with a nailing gun and nail cartridges.
- 2. Since the conventional installation of metal frames does not appear to provide real economies of time, many framing contractors prefer to use wood, the “old-fashioned” way.
- 3. When snipping and breaking off a piece of a metal stud, hands and clothing tend to get cut very easily.
- 4. Fumbling with the individual placement of a screw onto a screw gun and screwing into a conventional metal stud is cumbersome, annoying, and more time-consuming than simply applying a cartridge-loaded nailing gun to wood.
- 5. Tunneling spacing members through holes in a series of studs and then dealing with the connection of the tabs between the studs and the spacing members is cumbersome, awkward, and annoying.
However, metal stud installation does provide the following benefits:
-
- 1. Metal is virtually fireproof.
- 2. Metal is lightweight and easier to work with than wood.
- 3. Metal studs remain intact and square and do not warp.
- 4. Metal studs are currently about half the price of wooden studs.
- 5. Metal studs have precut holes for electrical and other cable running.
Accordingly, a need exists for a framing system that is easy to understand and quick to assemble, that does not require extensive cutting or snipping, and that is cost-effective as compared to current alternative methods.
A need also exists for a framing system that is more economical to use than wood frame systems and that is readily acceptable to architects, builders, installers, and end users.
A need also exists for a framing system that provides accurate spacing between studs and that is available with modular interchangeable components.
A need also exists for a framing system that offers a complete and simple solution rather than a partial solution to the entire installation process.
BRIEF SUMMARY OF THE INVENTIONThe present invention is a metal framing system for supporting the walls, floors, and ceilings of various building structures including residential and commercial buildings. The invention is an apparatus that is useful, for example, in the construction industry, and is also useful to end users who are performing home construction projects.
This invention provides for much simpler and speedier installation of wall/partition frames, resulting in greatly reduced labor costs while at the same time maintaining quality control in the integrity and accuracy of the installation.
The construction industry, whose workers are tradition- and trade-oriented, has been very slow to adopt any innovative methodologies or technologies. On the other hand, there is always a desire on the part of builders and consumers to reduce costs in building. The only way to satisfy both ends of the spectrum is to present a solution that creates significant cost-savings while at the same time has certain key ingredients: simple, easy to learn, practical (makes life easier for the worker), and also provides a complete solution, rather than incremental benefits.
The present invention provides ingredients to satisfy the worker and take away the worker's opposition to innovation. Those same ingredients have the effect of cutting costs for the builder. Time is money, and a speedy operation becomes a less expensive one.
Previous innovations have in most instances offered a solution to only a small part of the process, rather than to the whole thing. The present invention provides a complete solution. Importantly, the invention does not seek to replace steps in stud-wall building with a better process. Instead, it just eliminates some of the steps entirely for the tradesperson.
While saving money and streamlining operations, the invention maintains the integrity and accuracy of the installation; studs are square-plumb and on center for drywall installation.
The invention also provides a metal framing system that is easy to use, quick to assemble, and does not require metal cutting during frame assembly.
The invention also provides a complete modular framing system that is simple in form, easy to learn, and easy to use.
The invention also provides a metal wall framing system that eliminates some of the steps required to construct a conventional metal or wood frame, while providing a square, plumb, and on-center metal frame for supporting drywall or other wall materials.
The invention also provides a metal framing system that is significantly faster and more economical to assemble than other wood and metal framing systems.
The invention also provides a modular metal framing system that is easily used by an unskilled, lower-cost worker. The system is also intended for use by inexperienced do-it-yourself homeowners lacking the tools, knowledge, and experience of a skilled professional framer.
The invention also provides a metal wall framing system that does not require supplemental hardware, requires no supplemental fasteners, nails, electric tools or other power tools, or any measuring devices or cutting devices.
The invention also provides a modular metal framing system that can include an optional side spacer or bracer that provides spacing and alignment of studs and serves as a larger surface for supporting drywall and into which metal screws can be more conveniently secured to hold the drywall to the frame.
The present invention is directed to a modular metal framing system for constructing wall frames in virtually any type of building construction. The system is complete insofar as it requires virtually no additional hardware and can be readily used by unskilled labor. Metal wall frames constructed in accordance with the invention can be completed in a fraction of the time and at much lower cost than wood frames as well as other conventional metal frame systems.
In accordance with the invention, upper and lower metal channels are formed with a series of evenly-spaced locators or stops that accurately locate a series of metal studs along the channels. The channels also include retainers or prongs located adjacent to the locators or stops for fitting within slots formed in the studs. The channels further include scored or notched areas located adjacent to the stops and prongs for allowing a portion of each channel side wall to be crimped inwardly to hold a stud in place on the channel, or flexible clips that hold the stud in place along the channel.
In order to interconnect and mount a stud on a channel, the stud is simply moved along the channel with a sliding movement until the stud engages a stop. Just before the stud engages a stop, one or more locators or prongs slide into mating slots formed in the stud to hold and guide the stud into alignment with the stop. Notched or perforated portions in the channel sidewalls are then crimped inwardly to hold the stud in place within the channel. Alternatively, flexible clips are bent inward to hold the stud in place. This provides a bracing system for spacing and leveling.
According to a particular aspect of the invention, a metal stud assembly includes a stud adapted for constructing a metal wall frame between a pair of channel members, and an extender longitudinally slidably mounted within the stud. The stud includes a longitudinally-extending central column portion having a pair of opposite end portions, a pair of side walls formed on opposite sides of the central column portion, a first retainer, and at least one elongated alignment slot formed in the stud that is adapted to receive the first retainer formed on one of the channel members. The alignment slot is formed in at least one of the end portions of the central column portion. The extender includes an upper portion having side walls that are substantially parallel to the side walls of the stud, and a lower portion having side walls that join the upper portion side walls at a top end and which taper to smaller dimensions at a bottom end, such that the bottom end fits within the stud.
The stud can also include an indented portion formed in at least one of the side walls that is adapted to receive a spacer bar. The metal stud assembly can include a plurality of studs, as well as at least one spacer bar interconnecting adjacent ones of the studs, coupled to respective the indented portions formed in the studs.
The lower portion side walls of the extender can taper linearly inward. In this case, the extender can be formed with a push hole for pushing and sliding the extender within the stud. The metal stud assembly can also include a second retainer formed on the channel member, and the first retainer can have at least one slot formed therein that receives the second retainer.
According to another aspect of the invention, a metal wall frame system includes a series of metal studs according to the metal stud assembly described above. The system also includes a metal channel member, a series of stops formed at predetermined intervals along the channel member, and a series of retainer members formed at predetermined intervals along the channel member. The metal channel member has a floor portion and a pair of side walls upstanding from the floor portion. The series of metal studs is interconnected to the channel member. Each stud is butted against a respective one of the stops, and each stud receives a respective one of the retainer members.
The system can also include a series of spacer bars. Each spacer bar interconnects adjacent studs.
The stops can be formed as upstanding tabs struck from the channel member. In this case, the system can also include a series of longitudinally spaced crimp portions crimped inwardly from the side walls and locking the studs on the channel member. Each of the studs can include a socket, and each spacer bar can include a series of projections respectively extending into each of the sockets.
The metal channel member described above can be a lower channel member, and the system can also include an upper channel member interconnected to the extender. The extender can include an elongated slot, and the upper channel member can include a retainer member that engages the elongated slot to interconnect the upper channel member to the extender.
According to another aspect of the invention, a metal stud assembly includes a stud adapted to be used in the construction of a metal wall frame between a pair of channel members, and an extender longitudinally slidably mounted over the stud. The stud includes a longitudinally-extending central column portion having a pair of opposite end portions, a pair of side walls formed on opposite sides of the central column portion, a first retainer, at least one elongated alignment slot formed in the stud adapted to receive the first retainer formed on one of the channel members, and an indented portion formed in at least one of the side walls adapted to receive a spacer bar. The alignment slot is formed in at least one of the end portions of the central column portion. The extender includes an upper portion having side walls that are substantially parallel to the side walls of the stud, and a lower portion having side walls that fit over the stud.
The lower portion side walls of the extender can taper linearly inward.
The lower portion of the extender can join the upper portion side walls at a top end and taper to larger dimensions at a bottom end, such that the bottom end fits over the stud.
The assembly can also include a tapered section. The lower portion of the extender can fit over the stud and join the upper portion side walls at the tapered section. The tapered section provides a transition in dimensions between the upper portion and the lower portion.
The extender can be formed with a push hole for pushing and sliding the extender within the stud.
The metal stud assembly can also include a second retainer formed on channel member, and the first retainer can have at least one slot formed therein that receives the second retainer.
According to another aspect of the invention, a metal wall frame system includes a series of metal studs as described above. The system also includes a metal channel member having a floor portion and a pair of side walls upstanding from the floor portion, a series of stops formed at predetermined intervals along the channel member, and a series of retainer members formed at predetermined intervals along the channel member.

The aforementioned features and advantages of the invention will, in part, be pointed out with particularity, and will, in part, become apparent from the following more detailed description of the invention, taken in conjunction with the accompanying drawings, which form an integral part thereof.

DETAILED DESCRIPTION OF THE INVENTIONThe present invention will now be described in conjunction with the drawings, beginning with
The channel member 10 includes a flat, longitudinally-extending central floor 12 and a pair of upstanding parallel side walls 14 that are bent upwardly at right angles from each side of the floor 12. The channel member 10 is formed of a sheet metal material such as steel. A stud locator or stop member in the form of a tab 16 is struck or punched upwardly from the channel floor 12, leaving behind an open aperture 18 in the floor 12. As shown in
Preferably, the tab 16 is aligned vertically perpendicular to the floor 12 and laterally or transversely perpendicular to each side wall 14. In this manner, the tab 16 is square with both the floor and side walls of the channel member. A series of longitudinally-spaced tabs 16 is formed in the channel member 10, with each tab located at regular intervals. The tabs 16 can be located at predetermined longitudinal spacings of, for example, 16 and/or 24 inches.
One or more retaining members 20 are also struck out or punched up from the channel floor 12, leaving behind an open aperture 22 in the floor 12. As shown in
As shown in
As also shown in
As shown in
As can be appreciated from a review of
When the stud is fully and properly butted flat against the tab 16, it is also fully seated against the retainer members 20. In the example of the retainer member 20 of
At this point, the crimp portions 28 are bent inwardly from the side walls 14 of channel member 10 to form locking members 44. An open notch 46 is thus formed in the top edge 29 of each side wall 14. The locking members 44 can be closely spaced from the lips 36 on the stud 30 or in contact with the lips 36.
Alternatively, flexible clips 104 can be used in place of the locking members 44 to hold the stud in place. As shown in
The edge 108 of the clip 104 encroaching within the channel member 10 prevents movement of the stud 30 along the longitudinal direction of the channel in much the same manner as the locking members 44.
The general spacing of the interconnected channel member 10 and the stud 30 is shown in
A variation of this positioning, locating, aligning, and locking stud and channel framing system is shown in
A further variation of the invention is shown in
In the example of
In each of the prior examples, a pair of identical channel members 10 is aligned with one channel member directly above another. One channel member can be attached by fasteners to a floor and the other similarly attached to a ceiling. The tabs 16 on each channel member are vertically aligned one directly over the other and the channel members are carefully plumbed longitudinally parallel with one another as well.
The aligned channel members provide for the accurate vertically-plumbed alignment of the studs when the studs are pushed against a pair of aligned tabs 16, one tab being on the upper channel member and one on the lower channel member. In this case, the alignment slots 38 on each opposite end of the stud 30 are identical so that both ends of the studs are aligned by sliding the studs against a pair of stops or tabs 16 and interengaging the slots 38 with the retainer members 20 on each channel member 10. The crimp portions 28 or flexible clips 104 are then bent inwardly as described above.
A further embodiment of the invention is shown in
Rather than secure the upper or top portion 62 of the stud 30 directly to an overhead channel member 10, the extender 60 is adjusted vertically by sliding within the top portion 62 to engage the tabs 16 and the retainer members 20 on the channel member 10. The lower side walls 64 on the extender 60 have more compact dimensions than the upper portion 66, to form a snug sliding friction-fit against the side walls 34 of the top portion 62. The area between the lower side walls 64 and the upper portion 66 can be slightly tapered to provide a suitable transition in dimension. This prevents the extender from having a loose slack fit within the stud 30.
The upper portion 66 of the extender 60 can be transversely or laterally enlarged along the outwardly tapered portions 68 to prevent the extender 60 from sliding completely into the stud 30 by interfering with or abutting against the top edge 70 of the stud 30. As further seen in
Normally, the lower alignment slots 74 are engaged with the retainer members 20 on an upper channel member 10 attached to a ceiling. The retainer members 20 are thus spaced below the ceiling on which the upper channel member is fastened and spaced below the floor 12 of the upper channel member 10. With this arrangement, the top edge 78 of the extender 60 fits snugly against the floor 12 of the upper channel member. When the upper slots 72 are engaged with the retainer members 20, the top edge 78 of the extender 60 is spaced a small distance below the floor 12 of the upper channel member. This spacing accommodates settling of the ceiling and floors of the building structure and/or allows for additional loading which can compress and lower a ceiling.
When a stud 30 is attached directly to an upper channel member without an extender 60, it is suitable for use in load-bearing walls, providing the gauge of the metal stud meets the strength requirements for a load-bearing partition. However, when the extender 60 is used, it is loosely telescopically positioned within the stud and as such is not suitable for use in load-bearing walls.

In each of the embodiments discussed above, the upper and lower portions of each stud 30 are secured in place between the upper and lower channels 10 and held in place by stops such as tabs 16 which are accurately positioned on, for example, 16-inch or 24-inch spacings. An alternative embodiment of this arrangement is to secure the bottom portion of each stud 30 as described in any of the examples above, but to allow the upper portion of each stud to slide longitudinally within the upper channel member without being locked in place.
This can be achieved by eliminating the tabs 16 from the upper channel member 10. One or more “L” shaped retainer members 20 as shown in
In this embodiment, the upper channel member 10 need not be accurately aligned horizontally from wall to wall with the lower channel member 10. The lower channel member 10 is spaced and positioned where desired and the upper channel member 10 is simply approximately located above the lower channel member. Although the upper and lower channel members are aligned vertically in a common plane, they are not necessarily spaced and aligned accurately on 16-inch or 24-inch centers with one another. This allows for wall variations that may be wider on top than at the bottom or vice versa.
In this case, the lower ends of the studs 30 are secured within a channel member 10 as discussed in connection with the previous embodiments. The upper ends of the studs 30 (or the extenders 60) are simply slid onto the retainer members 20 and left to freely slide or “float” along the length of the retainer legs 26. Accurate spacing of the studs 30 can still be achieved, however, by the use of one or more central spacer or bracer bars 84 as shown in
