## Abstract

A fall arrest safety apparatus with blocking on a rope, comprising: a rigid body provided with a trunking for housing the rope, a securing system designed to swivel between a closed position to collaborate with the rope by blocking the latter at the bottom of the trunking in case of a fall, and an open position releasing access to the trunking for fitting or removal of the rope, and a control device to move said securing system from the closed position to the open position, and vice-versa, wherein the control device comprises a pair of gripping cleats able to be actuated simultaneously to stabilize and lock the securing system in the open position, the two gripping cleats being arranged side by side on a transverse pivot-pin integral to the pivoting securing system.

## Claims

### Claim 1

A fall arrest safety apparatus with blocking on a rope, comprising:
a rigid body provided with a trunking for housing the rope,
a securing system designed to swivel between a closed position to collaborate with the rope by blocking the latter at the bottom of the trunking in case of a fall, and an open position releasing access to the trunking for fitting or removal of the rope,
and a control device to move said securing system from the closed position to the open position, and vice-versa,
wherein the control device comprises a pair of gripping cleats able to be actuated simultaneously to stabilize and lock the securing system in the open position allowing access to the trunking, the two gripping cleats being arranged side by side on a transverse pivot-pin integral to the pivoting securing system.

### Claim 2 (depends on 1)

The safety apparatus according to claim 1, wherein a fixed blade made from plastic material is interposed between the two gripping cleats to prevent pressing of one of the cleats from causing movement of the other cleat.

### Claim 3 (depends on 1)

The safety apparatus according to claim 1, wherein each gripping cleat is equipped with a boss designed to come up against a stop of the body when the two cleats are not actuated simultaneously in the opening direction, making locking in the open position and access to the trunking impossible.

### Claim 4 (depends on 1)

The safety apparatus according to claim 1, wherein the securing system of a fall arrest apparatus comprises a blocking roller supported by a support device with a double swivelling arm, the common pivot-pin of the two cleats being integral to the double arm.

### Claim 5 (depends on 1)

The safety apparatus according to claim 1, wherein the securing system of an ascender device is equipped with a pivoting trigger, the two cleats being articulated on the trigger to be latched to the body in the open position.
