Rope pull bar

Abstract

A rope pull bar for pulling rope through conduit, said pull bar having a V-shaped notch or slot on an edge in the center of the bar with a perpendicular post on the bar extending outwardly adjacent the bottom of the V so that a rope may be looped around the post and the rope section from the upper run of the loop is positioned in the V-slot whereby when pulled in the direction opposite the point of the V, the upper run of rope will clamp the loose end of the lower run against the bar and provide a secure hold on the rope for further pulling.

1 . A rope pull bar comprising:
 a) an elongated handle, said handle having a central section that is generally in the shape of a rectangular parallelepiped with top, bottom, and side surfaces;   b) said central section having a V-shaped slot formed in one side thereof and, said slot extending in a side surface from the top to the bottom surface;   c) a post mounted on said top surface adjacent to one side of the bottom or point of said V-slot;   d) said post having a cap whereby, when a portion of a rope to be pulled is positioned in said slot with its loose end looped around said post and under said portion, manual force applied by gripping the handle on each side of said V-slot and pulling in the direction opposite from the point of the V-slot, will clamp the loose end of the rope to the handle and facilitate rope pulling.   
   
   
       2 . The rope pull bar of  claim 1  wherein the bar comprises a material selected from the group consisting of aluminum, aluminum alloys, steel, wood, and plastic. 
   
   
       3 . The rope pull bar of  claim 1  wherein said post comprises a shaft carrying said cap, said shaft having a knurled lateral surface for increasing the friction of the surface which contacts a rope. 
   
   
       4 . The rope pulling bar of  claim 1  wherein the depth of said V-slot is in the range of about ¼″ to about 1″, the handle is about ½″ to about 1½″ in thickness, and is about 1½″ to about 3½″ in width. 
   
   
       5 . A rope puller comprising:
 a) an elongated handle having end sections that may be manually gripped and a midsection connecting the end sections;   b) a V-shaped slot in the surface of the midsection for positioning and retaining a portion of a rope in said slot; and,   c) a post mounted in the midsection surface adjacent the bottom of said slot and extending outwardly from the surface; said post having a cap, whereby when a rope to be pulled is run through said notch and its loose end looped around said post and under itself, a user, by gripping the end sections of the handle and pulling in a direction opposite that in which the V notch points, will clamp the rope against the handle for continued pulling.   
   
   
       6 . The rope puller of  claim 5  wherein the handle comprising aluminum, aluminum alloy, steel, or plastic. 
   
   
       7 . The handle of  claim 5  wherein the post has a knurled, lateral surface. 
   
   
       8 . A rope puller comprising:
 a) an elongated handle having a flat, central surface with a V-shaped slot formed on one edge of said surface with the bottom of the V extends into the surface; said slot extending perpendicularly to said surface for the thickness of the handle;   b) a post mounted on the handle adjacent the bottom of the V-slot, said post having a retaining cap; and   c) a rope positioned in the V-slot, said rope having a diameter that is less than the depth of the V-slot, said rope having a loose end on the post side of said handle, said loose end being looped around said post and under itself whereby pulling the handle with substantially equal force on each side of the V-slot in the direction opposite that to which said V points will clamp the rope securely for further pulling.   
   
   
       9 . A method of pulling rope through a conduit comprising the steps of:
 a) providing a rope pull bar according to  claim 1 ;   b) providing rope having one end fastened to a line in a conduit and the other end being a loose end;   c) looping the rope around the post so that the rope segment that goes through the notch and to the conduit is the upper run and the loose end forms the lower run, whereby when pulling force is exerted on said rope from the upper run said rope will clamp the rope from the lower run tightly and securely against the handle.   
   
   
       10 . The method of  claim 9  including the step of applying pulling force by two people, each person gripping said handle. 
   
   
       11 . The method of  claim 9  including after step (c) the steps of pulling the handle in a first stroke, relaxing the pulling force thereby creating slack in the upper run rope segment, pulling the loose end of the rope to take up the slack in the rope, and, therefore, pulling the handle in a second stroke.
