Description

eleven

The invention relates to general engineering, in particular to devices that provide the possibility of movement and insurance when a person is lifted along a fixed rope.

The purpose of the invention is to improve the operating conditions by making the hull closed and reducing the number of operations for inserting and extracting the rope.

FIG. 1 shows a lock for a rope; a view to the glider in FIG. 2 is the same, top view V in FIG. 3, the operation of the locking element.

The clamp consists of a closed body 1 in which a cam 3 is mounted on axis 2, pushed by a spring 4, and a hinged hook 5 with a hole 6 for the connecting pin 7. A cylindrical finger 7 with a head 8 at one end and a radial hole 9 at the other end freely move between the protrusions 10 formed on the housing 1, in one of which there is a hole 11 for accommodating the connecting finger 7 o The head 8 of the finger 7 is made with a flat 12 and installed between the projections 10 with the possibility of translational movement. Lysk 12 facing the body with a gap that provides turning the flats 12 relative to the body at 75-80. The locking element 13, made, for example, in the form of a cable, is fixed at one end on the axis 2 of the cam 3, and the free end is located in the opening 9 of the connecting pin 7.

The device works as follows.

The cam 3 and the cover 5 mounted on the axis 2 turn relative to the body 1 counterclockwise to a position in which free rope can be inserted into the body 1. Thereafter, the crutch 5 is shifted in the opposite direction to coincide. the axis of its hole 6 is with a finger 7. A finger 7 enters the hole 6 of the cap 5. The finger 7 and the cover 6 are fixed by a locking element 13, the free end of which is inserted into the radial hole 9 of the finger 7 on the outside of the key 5. Thanks the presence of flats 12 facing the 1 and an aperture 9 at an angle of 75-80 to the axis is always in the position convenient for the g entry of the locking element 13. The gap And between the flats 12 and the housing 1 provides rotation of the finger 6 around its axis "

The extraction of the rope 14 from the housing 1 is carried out in reverse order. When the locking element 13 is bent in, the finger 7 rotates around its axis, freeing the free end of the cable as it exits from its opening. Then the finger 7 is pulled out of the opening 6 of the hinge 5, the cover 5 is rotated on the axis 2. of the cam 3 to a position that allows the cable 14 to be freely removed from the housing 1. With some skill, the operation of removing the rope is easily performed with one hand.
