Strut and clip assembly for stiffening a hanger rod
The present invention is a clip for use with a strut that at least partially surrounds a hanger rod for the purpose of providing stiffness to the hanger rod. The clip includes a handle portion, a rod-clamping portion, and a fulcrum spaced away from the handle portion. The fulcrum is for being mounted to the strut. The rod-clamping portion is for forcing the hanger rod into tight engagement with an engagement surface of the strut in response to the handle being actuated to an operational position. The present invention also relates to a hanger rod stiffening system that uses a clip and a strut, whereby a handle of the clip is actuated to force a rod-clamping portion of the clip into tight engagement with an internal surface of the strut.
1. A stiffening system for a hanger rod, comprising:
a strut that at least partially surrounds the hanger rod and extends along a length of the hanger rod, the strut including an internal engagement surface adjacent to the hanger rod, the strut further including a pivot region; and
a clip having a handle portion, a rod-clamping portion, and a fulcrum spaced away from the handle portion, the fulcrum being pivotably engaged in the pivot region of the strut, the rod-clamping portion forcing the hanger rod into tight engagement with the internal engagement surface of the strut in response to a pivoting movement about the fulcrum caused by the handle being actuated to an operational position.
2. The hanger-rod stiffening system of claim 1 , wherein the rod-clamping portion includes a groove for receiving the hanger rod.
3. The hanger-rod stiffening system of claim 2 , wherein the rod-clamping portion has a curved engagement surface, the hanger rod moving across the curved engagement surface as the handle is actuated to the operational position, the groove defining the curved engagement surface.
4. The hanger-rod stiffening system of claim 1 , wherein a body of the clip has a configuration that is generally in an L-shape, the handle portion being transverse to the rod-clamping portion.
5. The hanger-rod stiffening system of claim 1 , wherein the fulcrum is located within the rod-clamping portion.
6. The hanger-rod stiffening system of claim 1 , wherein the fulcrum is defined by first and second protruding surfaces extending away from each other, the first and second protruding surfaces engaging the pivot region of the strut.
7. The hanger-rod stiffening system of claim 1 , wherein the actuation of the handle to the operational position causes the rod-clamping portion to be wedged between the hanger rod and the pivot region of the strut.
8. The hanger-rod stiffening system of claim 1 , wherein the handle extends away from the strut in an insertion position when the clip is initially inserted into the strut.
9. The hanger-rod stiffening system of claim 8 , wherein, in response to manual force on the handle, the handle is moved from the insertion position to the operational position that forces the hanger rod into tight engagement with the internal engagement surface of the strut.
10. The hanger-rod stiffening system of claim 1 , wherein the clip further includes latching fingers to engage inner surfaces of the strut after the handle is actuated to the operational position.
11. The hanger-rod stiffening system of claim 1 , wherein the latching fingers move toward each other as the handle is moved toward the operational position, the latching fingers resiliently spring outwardly onto the inner surfaces of the strut in response to the handle reaching the operational position.
12. The hanger-rod stiffening system of claim 1 , wherein the rod-clamping portion includes a plurality of rod-engaging surfaces, the plurality of rod-engaging surfaces being selectively useful in providing tight engagement to multiple sizes of hanger rods within the strut.
