Abstract
Abstract The specification describes a rope clamp with at least one clamping body, which can be moved between wedge-shaped guiding faces. A rear part of the clamping body remote from the rope is constructed as a pivoting edge or is rounded and on actuation of the clamp the clamping body slides into its clamping position with the rear part on an associated guiding face comes into engagement with the rope. Following this the clamping body swings about the pivoting edge as a pivot axis until the whole clamping face lies against the rope. The clamping face is so arranged that in the clamping position the front edge of the clamping face lies behind, in terms of the pulling direction, a line drawn perpendicular to the direction of pulling through the axis of rotation or at the most lies on this axis. Furthermore for actuating the clamp to release it the clamping body is first swung about its axis of rotation formed by its pivot edge before it begins its sliding movement on the guiding face.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
239 words
A releasable clamp comprising a. an elongated housing having a longitudinal axis, an inner end and an outer end, said inner end having an inner cam surface converging with the longitudinal axis toward the inner extremity thereof, b. a slide member longitudinally movable relative to said housing and having a cam slot diverging from said longitudinal axis toward the inner end of the housing, c. an elongated clamping member within said housing having an inner end and an outer end, the inner end having an elongated gripping surface with a leading edge at the inner end thereof at one side adjacent said longitudinal axis and a rounded abutment on the other side for slideable and rocking engagement with said inner cam guide surface, the outer end of said clamping member comprising a shank portion and a cam follower engageable with the cam slot, and d. spring means biased to slide the slide member toward the inner end for longitudinal movement of the clamping member from a release position toward the inner end until the converging cam guide surface brings the leading edge of the gripping surface into engagement with the object to be clamped and thereafter to lock the clamping member by rocking said member about the point of contact of said abutment with said cam surface by the camming action of the cam slot until the remainder of the gripping surface firmly engages the object to be clamped.
Claim 2
Dependent Claim
239 words
A releasable clamp comprising a. an elongated housing having a longitudinal axis, an inner end and an outer end, said inner end having an inner cam surface converging with the longitudinal axis toward the inner extremity thereof, b. a slide member longitudinally movable relative to said housing and having a cam slot diverging from said longitudinal axis toward the inner end of the housing, c. an elongated clamping member within said housing having an inner end and an outer end, the inner end having an elongated gripping surface with a leading edge at the inner end thereof at one side adjacent said longitudinal axis and a rounded abutment on the other side for slideable and rocking engagement with said inner cam guide surface, the outer end of said clamping member comprising a shank portion and a cam follower engageable with the cam slot, and d. spring means biased to slide the slide member toward the inner end for longitudinal movement of the clamping member from a release position toward the inner end until the converging cam guide surface brings the leading edge of the gripping surface into engagement with the object to be clamped and thereafter to lock the clamping member by rocking said member about the point of contact of said abutment with said cam surface by the camming action of the cam slot until the remainder of the gripping surface firmly engages the object to be clamped.
Claim 3
Dependent Claim
239 words
A releasable clamp comprising a. an elongated housing having a longitudinal axis, an inner end and an outer end, said inner end having an inner cam surface converging with the longitudinal axis toward the inner extremity thereof, b. a slide member longitudinally movable relative to said housing and having a cam slot diverging from said longitudinal axis toward the inner end of the housing, c. an elongated clamping member within said housing having an inner end and an outer end, the inner end having an elongated gripping surface with a leading edge at the inner end thereof at one side adjacent said longitudinal axis and a rounded abutment on the other side for slideable and rocking engagement with said inner cam guide surface, the outer end of said clamping member comprising a shank portion and a cam follower engageable with the cam slot, and d. spring means biased to slide the slide member toward the inner end for longitudinal movement of the clamping member from a release position toward the inner end until the converging cam guide surface brings the leading edge of the gripping surface into engagement with the object to be clamped and thereafter to lock the clamping member by rocking said member about the point of contact of said abutment with said cam surface by the camming action of the cam slot until the remainder of the gripping surface firmly engages the object to be clamped.
Claim 4
Dependent Claim
239 words
A releasable clamp comprising a. an elongated housing having a longitudinal axis, an inner end and an outer end, said inner end having an inner cam surface converging with the longitudinal axis toward the inner extremity thereof, b. a slide member longitudinally movable relative to said housing and having a cam slot diverging from said longitudinal axis toward the inner end of the housing, c. an elongated clamping member within said housing having an inner end and an outer end, the inner end having an elongated gripping surface with a leading edge at the inner end thereof at one side adjacent said longitudinal axis and a rounded abutment on the other side for slideable and rocking engagement with said inner cam guide surface, the outer end of said clamping member comprising a shank portion and a cam follower engageable with the cam slot, and d. spring means biased to slide the slide member toward the inner end for longitudinal movement of the clamping member from a release position toward the inner end until the converging cam guide surface brings the leading edge of the gripping surface into engagement with the object to be clamped and thereafter to lock the clamping member by rocking said member about the point of contact of said abutment with said cam surface by the camming action of the cam slot until the remainder of the gripping surface firmly engages the object to be clamped.
Claim 5
Dependent Claim
30 words
A clamp as defined in claim 1 wherein the longitudinally movable slide member is actuated and controlled by a sleeve member at least partly surrounding and slideable on the housing.
Claim 6
Dependent Claim
22 words
A clamp as defined in claim 1 wherein the cam follower on the shank of the clamping member is a transverse pin.
Claim 7
Dependent Claim
31 words
A clamp as defined in claim 1 wherein the housing has a longitudinal slot in one side and along the length thereof for lateral insertion of the object to be clamped.
Claim 8
Dependent Claim
53 words
A clamp as defined in claim 1 wherein the housing has a longitudinal slot in one side and along the length thereof for lateral insertion of the object to be clamped and the slide member is actuated and controlled by a sleeve member slideable on the housing and having a corresponding longitudinal slot.
Claim 9
Dependent Claim
24 words
A clamp as defined in claim 1 having two opposed elongated clamping members actuated by opposed converging cam slots, cam surfaces and cam followers.
