Problems solved by technology

[0012] With this type of device, the effective range of braking positions is within the small travel of the lever 58, so it is difficult for the user to find the proper braking position to be able to continue traveling at the desired speed

Embodiment Construction

[0022] figure 2 It is an exploded perspective view of an embodiment of the protective rope device that can provide precise control of the running speed of the rope. The figure shows the figure 1 Parts with the same function as those of the conventional device shown, and even if these parts sometimes have different shapes, are denoted by the same reference numerals.

[0023] The figure shows the flange plate 18 used as a reference part for assembling the other components. The cam 14 and plate 30 form a single part hinged about a pivot pin 32 . This single part is hereinafter indicated as 'cam 14'.

[0024] The lever 58 is shown in its inoperative position, hinged on the cam 14 by means of a pivot pin 60, which is folded back to conform to the general external shape of the device.

[0025] In order to be able to precisely control the running speed of the rope, the base of the rod 58 is provided with a post 100 parallel to the pivot pin 60 on the side opposite to the part fo...

Abstract

The invention relates to a self-arresting rope belay device comprising a cam arranged to clamp the rope when the rope is under tension, and a lever arranged to act on the cam to progressively release the rope by manual action on the lever. The lever acts on the cam respectively with a geared-down effect in an initial part of its release travel, and with a direct effect in a final part of its travel. This results in the relative movement of the cam with respect to the lever being smaller in the initial part of the travel than in the final part, which enables accurate adjustment of the braking effort and of the running speed of the rope in the initial part of travel of the lever.

Description

technical field [0001] The present invention relates to a self-arresting belay device for a rope, which can be used as a descender or for belaying a climber. The device can be designed to automatically grip the rope once it is under tension. If the user wants the rope to run freely, he has to manually operate the lever. Background technique [0002] figure 1 A conventional anti-slip device as described in European Patent EP 0398819 is partially shown. The device comprises a pair of pulleys 12 and 14 housed between two parallel flange plates, one of which is indicated at 18, hereinafter referred to as the base flange plate. The first pulley 12 is fixedly mounted on the base flange plate 18 via the fixing element 22 . The pulley 12 is provided with a circular top sector of a guide groove for guiding the rope 26 and a braking surface 28 facing the second pulley 14 . The braking surface 28 is substantially flat. [0003] The second pulley 14 is secured to a support plate 3...
