Abstract

A fitting for hanging a piece of channel framing includes a coupling component having opposite longitudinal ends, a length extending between the opposite longitudinal ends, a coupling longitudinal portion configured to be secured in the external fitting groove of the channel framing body, and an exposed longitudinal portion configured to extend outward from one of the open groove ends of an external fitting groove for connection to a rod to hang the piece of channel framing from an elevated structure when the coupling longitudinal portion of the coupling component is received in the external fitting groove.

First claim

What is claimed is:

1. A fitting for a piece of channel framing including an elongate channel framing body having opposite longitudinal ends, a length extending between the opposite longitudinal ends, and a fitting side defining an external fitting groove extending lengthwise of the body, wherein the external fitting groove has opposite open groove ends at the opposite longitudinal ends of the channel framing body, the fitting comprising:
a coupling component comprising an elongate body generally in the form of a block, the elongate body having opposite longitudinal ends, a length extending between the opposite longitudinal ends, a coupling longitudinal portion configured to be secured in the external fitting groove of the channel framing body, and an exposable longitudinal portion configured to extend outward from one of the open groove ends of the external fitting groove, wherein the coupling longitudinal portion of the elongate body has a generally double dovetail cross-sectional shape, whereby an upper portion of the coupling longitudinal portion has a length extending along the length of the elongate body and a generally dovetail cross-sectional shape for sliding insertion lengthwise into the external fitting groove, and a lower portion of the coupling longitudinal portion has a length extending along the length of the elongate body and a generally dovetail cross-sectional shape, which is inverted relative to the upper portion of the coupling longitudinal portion, for sliding insertion lengthwise in an external fitting groove of a different piece of channel framing to connect the pieces of channel framing to one another,
wherein the length of the upper portion of the coupling longitudinal portion extends along the length of the lower portion of the coupling longitudinal portion,
wherein the elongate body has opposite upper and lower faces and a first opening extending through the upper and lower faces, wherein the first opening is defined by the exposable longitudinal portion of the elongate body,
wherein the elongate body has a second opening extending through the upper and lower faces, wherein the second opening is defined by the coupling longitudinal portion of the elongate body.

2. The fitting set forth in claim 1 , wherein the first opening is configured to receive a first rod, the elongate body having a third opening extending through the upper and lower faces and spaced apart from the first opening along the length of the elongate body, wherein the second opening is defined by the exposable longitudinal portion of the elongate body and is configured to receive a second rod.

3. The fitting set forth in claim 1 , wherein the coupling longitudinal portion of the elongate body is slidably insertable lengthwise into the external fitting groove of the channel framing body through one of the open groove ends of the external fitting groove, wherein the coupling longitudinal portion of the elongate body is configured to inhibit withdrawal of the elongate body from the external fitting groove in a direction transverse to the length of the external fitting groove when the coupling longitudinal portion of the elongate body is slidably inserted into the external fitting groove.

4. The fitting set forth in claim 1 , in combination with the piece of channel framing, wherein the coupling longitudinal portion is connected to the fitting side of the channel framing body, and the exposable longitudinal portion extends outward from one of longitudinal ends of the channel framing body.

5. The fitting in combination with the piece of channel framing set forth in claim 4 , wherein the channel framing comprises a slotted side opposite the fitting side of the channel framing body, the slotted side defining an elongate slot extending lengthwise of the channel framing body and into an open interior of the channel framing body.

6. The fitting in combination with the piece of channel framing set forth in claim 4 , wherein the first opening is configured to receive a rod to hang the piece of channel framing from an elevated structure when the coupling longitudinal portion of the coupling component is received in the external fitting groove.

7. The fitting in combination with the piece of channel framing set forth in claim 4 , wherein the coupling longitudinal portion of the coupling component is configured to inhibit withdrawal of the coupling component from the external fitting groove in a direction transverse to the length of the external fitting groove.

8. The fitting set forth in claim 1 , wherein the generally dovetail cross-sectional shapes of the upper and lower portions of the coupling longitudinal portion are mirror images of one another in reference to an intervening plane extending lengthwise of the elongate body.
