Definitions

  • the present invention relates to a descending-and-blocking tool lever on ropes or halyards in tension with variability of the dosage of the descending function.
  • An attachment means of the operator close to the passage of the rope and an extensible lever opposite the attachment means to release in a controlled manner the locking and offer a progressive descent
  • the existing tool EP 1 329 242 A1 offers these possibilities but without dosage depending on the type and the rope texture used.
  • the invention aims to remedy the following three problems:
  • the tool responds to these problems by the wedging of the rope stretched between the two flat and looking surfaces of the sheaves.
  • the point of attachment of the user is almost in the axis of passage of the stretched rope thus defined.
  • Progressive smooth release from the blocking function to the descending function thanks to the extendable handle, which is symmetrical on the opposite side of the attachment point, depends on the diameters and the roughness of the ropes by the positioning of carabiners. or moving axes in the holes placed at the edge of the sheaves and the passage of the rope. This results in four possible braking configurations that must be determined by testing each rope.
  • Figure 1 shows a left view in the open position showing the establishment of the rope in the tool.
  • Figure 2 shows a view of the back of the tool.
  • Figure 3 shows four profile sections in the closed position and in tension with the four possible braking positions.
  • the choke descender on tensioned rope consists of a first so-called fixed cheek 1 enlarged by an extensible maneuvering handle 1 1, and a second mobile cheek 2 mirrored in the closed position of the cheek 1 (without the handle). They are drilled at 9 and 10 at the top opposite the handle 1 1 to form the point of attachment of the operator.
  • a tubular spacer 14 keeps the cheeks to traction, without torsion stress.
  • the longitudinal axis 16 of the tool is approximately in the middle of the tool and places the fixing holes 9 and 10 and the handle 1 1 on either side of this axis.
  • the so-called fixed cheek 1 has on either side of the axis 16 and substantially equidistant from the operating handle 1 1 and the perforations 9 and 10, two friction surfaces 1 8 and 19 "cut” in sheaves 3 and 4. These sheaves 3 and 4 are fixed on this cheek 1 by a blind bolt 12 for the 4 and a bolt 1 3 with shoulder nut for the 3 which also serves as a fixing point and axis of rotation of the mobile cheek 2.
  • the thickness of the sheaves 3 and 4 (drawing 2) provides a substantially wider passage than the line 1 7 between the cheeks 1 and 2.
  • the line 1 7 passes in a straight line from top to bottom along the axis 1 6 by touching the friction surfaces 1 8 and 19, and the holes 9 and 10 and the tube 14, and the handle 1 1.
  • the handle is extensible.
  • the device according to the invention is summarized by a variable lever action between the surfaces and points of friction, and the rope, as well as by the possible dosage thanks to the expandable handle.
  • the operator presents the open tool (drawing 1) so as to place the rope 17 along the axis 16 between the surfaces and friction points. He can then close the tool on the rope by rotating the cheek 2 to the mirror position and striking a carabiner 20 in the holes 9 and 10.
  • Position 2 a point of friction shifted down to 7-8.
  • Position 3 two friction points offset at the top 5-6 and at the bottom 7-8.
  • Position 4 a staggered point at the top 5-6.
  • the same tool can be developed "in duplicate" namely that the fixed cheek would serve as a mirror to provide a second pair of sheaves and a second mobile cheek, so as to use the tool on two lines.
  • the tool functions as a down-braking device if the rope tension is released.
