Channel clip
A channel clip used to secure an acoustically isolated ceiling via an acoustic isolator, which includes a centrally positioned bore for attachment to the isolator and an interior protrusion for limiting movement of a channel within the clip. A method of manufacturing a channel clip, including extrusion of tubing from which the clip is cut, and a method of installing a channel clip are also provided.
1 . A detachable channel clip for supporting a U-shaped channel, the clip comprising:
a top wall having a first end and a second end opposite the first end;
a bottom wall parallel to the top wall, and having a first end and a second end opposite the first end;
a first side wall extending from the first end of the top wall to the first end of the bottom wall;
a second side wall parallel to the first side wall and extending from the second end of the top wall to the second end of the bottom wall;
a protrusion extending from the first side wall and towards the second side wall, and configured to reduce movement of the channel disposed in the clip along a direction parallel to the first and second side walls, wherein a portion of the second side wall directly opposite the protrusion and facing the protrusion has a planar surface configured to engage and support a web of the U-shaped channel when the channel is inserted into an interior volume of the clip, and
a bore extending through a center of the top wall;
wherein the interior volume is dimensioned to allow the web of the U-shaped channel to pass completely through and be supported by the planar surface of the second side wall.
2 . The channel clip of claim 1 , wherein the clip comprises a unitary body formed by an extrusion process.
3 . The channel clip of claim 1 , wherein the unitary body has a rectangular cross section.
4 . The channel clip of claim 1 , wherein the protrusion is disposed at a location on the first side wall that is approximately 0.25 inches from the bottom wall to limit the channel from moving relative to the clip.
5 . The channel clip of claim 1 , wherein the protrusion has a rectangular cross section.
6 . The channel clip of claim 1 , wherein the bore is a threaded bore.
7 . The channel clip of claim 6 , wherein the bore is a first bore, and the clip further comprises a second bore that is a threaded bore and that extends through the center of the bottom wall.
8 . The channel clip of claim 6 , wherein the channel clip is configured to be supported by an acoustic isolator via the first bore.
9 . The channel clip of claim 7 , wherein the channel clip is configured to support at least one secondary structure via the second bore.
10 . The channel clip of claim 1 , where the channel clip is configured to interchangeably accommodate a ¾″ cold rolled channel, a 1½″ cold rolled channel, a 2″ cold rolled channel, and a 2½″ cold rolled channel.
11 . The channel clip of claim 1 , wherein
the protrusion is configured to constrain a flange of the channel, and
the channel extends through an interior volume of the clip defined by the top wall, the bottom wall, the first side wall, and the second side wall.
12 . The channel clip of claim 1 , wherein the protrusion is a first protrusion, and further comprising at least one second protrusion, the first and second protrusions positioned to form a notch to limit movement of the channel disposed in the clip along the direction parallel to the first and second side walls.
13 . The channel clip of claim 1 , wherein the protrusion limits movement of the channel to between approximately 0.180 and 0.210 inches of distance along the direction.
14 . A channel clip for supporting a channel, the clip comprising:
a top wall having a first end and a second end opposite the first end;
a bottom wall parallel to the top wall, and having a first end and a second end opposite the first end;
a first side wall extending from the first end of the top wall to the first end of the bottom wall;
a second side wall parallel to the first side wall and extending from the second end of the top wall to the second end of the bottom wall;
a first protrusion extending from the first side wall and towards the second side wall, wherein the first protrusion is perpendicular to the first side wall,
a bore extending through a center of the top wall, and
at least one second protrusion extending from the first side wall and towards the second side wall adjacent the first protrusion, wherein the at least one second protrusion is perpendicular to the side wall,
wherein the first and second protrusions positioned to form a notch that accommodates a flange of the channel therebetween to limit movement of the channel disposed in the clip along the direction parallel to the first and second side walls.
