Abstract
The invention relates to an anti-fall device automatically lockable on a safety rope, wherein the two cheeks of the gutter comprise a blind notch in L form, opening out on the edge of the corresponding cheek, while the ends of the pivot pin of the two elements of the lever project laterally in order to engage in said notches. The free end of that element of the lever which does not bear the cam is mounted to rotate about a pin sliding in a slideway made on an extension of one of the cheeks of the gutter, this pin being elastically loaded in the direction opposite that of the notches. A pivoting lock borne by one of the cheeks of the gutter is maintained elastically in a position in which it closes the bottom of the notch of the corresponding cheek.
Claims12
A safety device for use in securing a harness to a rope-like object comprising,
- a generally U-shaped gutter bracket having a bottom defined between opposing cheeks each of which extends from said bottom to a free edge, an elongated opening defined between said free edges of said cheeks, a lever having first and second elements which are articulated to one another about a first pivot means, said second element being pivotally connected relative to said cheeks of said gutter bracket about a second pivot means which is moveable relative to said cheeks in a slideway extending along one of said cheeks, said first element having one end adjacent said first pivot means defining a cam and a second end adapted to be engaged by a harness, a generally L-shaped notch in each of said cheeks of said gutter bracket, each L-shaped notch having a first slot opening to an adjacent free edge of said cheeks and a second slot extending generally toward second pivot means, a pivotable lock mounted to one of said cheeks and moveable between a first locking position closing said second slot of said L-shaped notch to an open position wherein said pivotable lock is spaced from said L-shaped notch, said first pivot means having end portions extending outwardly with respect to said first and second elements of said lever so as to be selectively engageable with said L-shaped notches of said cheeks of said gutter bracket when said lever is pivoted from a first open position in which said lever does not obstruct the opening between said cheeks of said gutter bracket, thereby allowing the rope-like object to be inserted therebetween, to a second end position wherein said first pivot means is engaged within said L-shaped notches with said cam positioned so as to be engageable against the rope-like object extending between said cheeks and against said bottom of the gutter bracket, and first resilient means for urging said second pivot means away from said L-shaped notches to thereof urge said first pivot means toward a seated engagement within said second slots of said L-shaped notches when said first pivot means is in said second position, whereby when said first pivot means is within said second slots of said L-shaped notches said pivotable lock moves to said first locking position to retain said second pivot means within said second slots.
