CLAMPING DEVICE FOR ROPE Russian patent published in 2004 - IPC

FIELD: means for fastening cables or ropes.

SUBSTANCE: one end of a rope is preliminary arranged inside the housing. The other end passes through the housing to form a loop and is secured inside the housing with the use of two same spring-loaded rotation bodies. The first end is preliminary secured in the holder, which is mounted inside the housing for permitting movement. The holder has two grooves for rotation bodies and through passage used for passing and arranging the rope. The longitudinal sizes of the grooves are larger than the diameter of the rotation bodies. The flat sides of the stop surfaces for the rotation bodies face the outlet opening of the holder and outlet opening of the housing. Two sides of the inner space of the housing, each of which provides interaction with the corresponding rotation body, are curvilinear. The inclination between the tangents to the generatrix of each curvilinear sides and aligned axes of the inlet and outlet openings of the housing increases from the inlet to the outlet port of the housing so that the diametrical size of the curvilinear side increase from the inlet to the outlet openings of the holder. In addition, the device is provided with a screw whose threaded part is positioned in the through threaded port of the housing for permitting interaction with the outer side of the holder and provided with a handle. There is a ring groove between the handle and threaded part.

EFFECT: enhanced reliability of clamping and expanded functional capabilities.
