ABSTRACT:
A rope grip having a receiving member with a pair of substantially parallel side walls spaced apart a distance sufficient to receive a rope therebetween. The side walls are joined along one side edge thereof so as to define a first engagement. An engagement member slidably received within the side walls and having a second engagement surface and being in a facial spaced relationship with regard to the first engagement surface. A movement restricting member, is positioned to define and restrict the movement of the engagement member within the pair of side walls. An actuating arm having a first end and a second end is secured to the engagement member in such a manner to allow for pivotal movement of the actuating arm, whereby the first end moves in response to a force exerted upon the second end and the first end makes contact with the receiving member causing the engagement member to move within the pair of side walls, such movement of the engagement member causes the second engagement surface to either move closer to or further away from the first engagement surface and accordingly secure or release the rope grip from the rope. A pair of planar members are secured to and depend away from the second engagement surface. The planar members are angularly positioned with respect to the second engagement surface and allow the rope to be angularly displaced with respect to the rope grip. Such placement of the planar members prevents the rope grip from damaging the rope when the rope grip is secured to the rope.
