Wall framing system, method and product
View Patent ↗An improved system, method and product are disclosed for attaching non load-bearing metal wall studs to an overhead metal track in metal stud framing systems used for wall partitioning, in a manner that allows the overhead track to deflect under load without transferring the load to the studs and any attached wall partitions. The system features compression spring attachment products that frictionally engage overlapping flange portions of the track and studs so that any overhead load-induced movements of the track are not transferred from the track to the studs, or to any wall partitions attached to the studs.
1. An asymmetrical spring clip for use in interconnecting a generally vertically extendible flanged wall stud and a generally horizontally extendible flanged member, the wall stud having a flange and an angled flange return, the flanged member having a flange terminating at a distal edge, the spring clip comprising:
first and second opposed clamping end portions, the clamping end portions being asymmetrical relative to one another and configurable to apply a clamping force to overlapping flanges of the wall stud and the flanged member, wherein the first clamping end portion has a generally flat shape and is positionable generally flush against an outer surface of the flange of the flanged member, and wherein the second clamping end portion is positionable to contact an inner surface of the flange of the wall stud; and
an asymmetrical clip body portion interconnecting said opposed clamping end portions and biasing said opposed clamping end portions toward one another for applying the clamping force, the clamping force being sufficient to clip the wall stud and flanged member together while allowing relative vertical sliding movement between the flanges so that the flanged member can move vertically relative to an erect wall stud in response to changes in a supported load, the body portion configured to extend from the first clamping end portion, around the distal edge, around the flange return, toward the inner surface of the flange of the wall stud, and to the second clamping end portion;
wherein the spring clip comprises no more than two bends having an interior included angle of less than 90°;
wherein said clamping end portions and said body portion are comprised of a springy material; and
wherein said opposed clamping end portions each includes an upturned lip end portion, with the lip end portions of the opposed clamping portions being upturned in directions opposite one another.
2. A spring clip according to claim 1 wherein said springy material comprises a flat strip of springy material.
3. A spring clip according to claim 2 wherein said springy material is a metal material.
4. A spring clip according to claim 1 wherein said springy material comprises a springy metal material operable to provide a dynamic friction fit between the wall stud and the flanged member.
5. A spring clip according to claim 1 wherein said springy material comprises a springy wire material.
6. A spring clip according to claim 1 wherein said springy wire material is a metal material.
7. The spring clip of claim 1 , wherein the spring clip comprises only one bend having an interior included angle of less than 90°.
