Abstract

A multipurpose rope clamp may be attached to a support or suspended from a rail as desired. The clamp provides clamping channel in an open channel between a back plate and a front tongue. Rope is prevented from slipping out of the mouth of the channel by rope guides defining open rope guide channels which open in a direction opposed to the rope gripping channel to form a partial cover for the rope gripping channel. The guides may be lugs spaced to either side of the front tongue so that a bight of rope may be manipulated behind the lugs into the rope gripping channel. Preferably another rope guide channel is provided to form a bight of rope in the clamp into a U-shape.

Claims

1. A rope clamp optionally attachable to a support comprising a molded unit comprising a back carrier plate having an integral parallel front tongue spaced therefrom defining a substantially straight open rope gripping channel therebetween;

an inner face of the front tongue and an inner face of the back plate being provided with converging clamping ribs to narrow said open rope gripping channel towards a channel base thereof;

the back carrier plate extending to either side of the front tongue and having a rope guide to each side of the front tongue, one of the rope guides defining an open rope entry channel opposed to said open rope gripping channel and the other of the rope guides defining a rope exit channel opposed to said open rope gripping channel to guide the rope between the clamping ribs, each of the rope guides being spaced from the front tongue by a distance sufficient to pass a bight of rope between said tongue and the respective rope guide for engagement or disengagement in said open rope gripping channel.

2. A rope clamp as claimed in claim 1 which includes a straight tubular rope guide parallel to said rope gripping channel and said entry and exit channels, whereby a bight of rope in said rope clamp is formed into a U-shape, one run of rope confined in the rope gripping channel forming one leg of the U, another run of rope in the tubular rope guide forming another leg of the U and a loop of rope between said runs forming a web of the U.

3. A rope clamp as claimed in claim 2 in which each of said one and said other rope guides comprises a lug having a free distal end, the lug upstanding from one of said back plate extensions to project towards said channel base and having a root substantially parallel to said channel base.

4. A rope clamp as claimed in claim 3 in which each of said one and said other rope guides comprises an L-shaped lug of which one limb of the L constitutes a roof portion parallel to said channel base and upstanding from the back plate, and the other limb of the L projects towards said channel base substantially flush with said front tongue.

5. A rope clamp as claimed in claim 2 in which said channel base of said gripping channel and said tubular rope guide are adjacent each other and are molded integrally.

6. A rope clamp as claimed in claim 1 in which the front tongue is spaced from the back plate by a distance substantially corresponding to the diameter of rope for which it is to be used.

7. A rope clamp as claimed in claim 1 in which the back plate includes attachment means for attaching it to said support.
