Abstract

The device has a case with two parts (a, b) extended from each other using two springs, to fix the case on vertical upright rods of a ladder. The case has jaws (11-13), and a wing screw passes through holes of the jaws to directly lock the jaws on a gutter (4), to clasp the gutter against which the ladder is laid. The case is also fixed on a bar of the ladder.

Description

La présente invention concerne un dispositif de sécurité qui permetThe present invention relates to a safety device which enables

d'immobiliser une échelle afin qu'elle ne glisse pas lors de son utilisation 1  to immobilize a ladder so that it does not slip during its use 1

Pour aller sur un toit, on pose l'échelle contre un cheneau. A la montée et surtout à la descente, cette dernière risque de "glisser" entraînant la personne qui l'utilise dans une chute qui peut provoquer de graves blessures.  To go on a roof, we put the ladder against a crawler. At the climb and especially the descent, the latter may "slip" causing the person who uses it in a fall that can cause serious injury.

Le dispositif, selon l'invention, permet de remédier à cet inconvénient. Il comporte en effet deux caractéristiques. - _ La première est un boîtier venant se fixer sur l'un ou l'autre des montants verticaux de l'échelle.  The device according to the invention overcomes this disadvantage. It has two features. The first is a housing which is fixed on one or the other of the vertical uprights of the ladder.

La deuxième est une machoire qui enserre le cheneau Selon des modes particuliers de réalisation _Le boitier venant sur l'échelle doit comporter deux ressorts afin qu'il s'adapte à la largeur de cette dernière.  The second is a jaw that encloses the cheneau According to particular embodiments _The case on the scale must have two springs so that it fits the width of the latter.

_La machoire est articulée et à l'arrière, à l'aide d'un écrou "papillon" (14) non 15 représenté, on resserre cette dernière pour qu'elle bloque le cheneau (4) par effet de levier.  The jaw is hinged and at the rear, using a nut "butterfly" (14) not shown, it tightens the latter to block the cheneau (4) by leverage effect.

Les dessins annexés illustrent l'invention La figure (1) représente le dispositif de l'invention La figure ( 2) est une coupe représentant le bottier ( 2) se fixant sur l'échelle ( 6) 20 La figure ( 3) représente la mâchoire inférieure (12) et les mâchoires supérieures (12 et 13) En référence à ces dessins le dispositif (1) comporte un boîtier (2) de la figure ( 2) dont la partie ( a) est amovible. Écartée de la pièce ( b) par deux ressorts (9) celle ci s'adapte à la largeur du montant vertical de l'échelle ( 6) qui est serré sur ce dernier par les vis ( 7 et 8) Une vis ( 5) ou un levier à serrage rapide, non représenté dans la figure (1) traverse (b) de la figure ( 2) et passe au travers de lumières des mâchoires ( 11-12-13) Cette dernière peut ainsi être réglée en profondeur afin qu'elle vienne se bloquer directement sur le cheneau (4)La vis "papillon" (14) permet le blocage de la mâchoire (11-12-13) Le border ( 2) peut aussi bien se positionner sur un barreau (10) que sur un montant de l'échelle (6) La mâchoire (1112-13) peut enserrer une branche si l'on désire que l'échelle ( 6) se positionne dans un arbre. Dans tous les cas l'échelle est solidaire de son support et une mâchoire amovible, non représentée, peut être remplacée pour s'adapter à son point de serrage ainsi que sur différentes échelles.  The accompanying drawings illustrate the invention. FIG. 1 represents the device of the invention. FIG. 2 is a cross-section showing the casing 2 attached to the ladder 6. FIG. lower jaw (12) and the upper jaws (12 and 13) With reference to these drawings the device (1) comprises a housing (2) of Figure (2), the portion (a) is removable. Spread from the piece (b) by two springs (9) it adapts to the width of the vertical upright of the ladder (6) which is tightened on the latter by the screws (7 and 8) A screw (5) or a quick-release lever, not shown in Figure (1) crosses (b) of Figure (2) and passes through the slots of the jaws (11-12-13) The latter can thus be adjusted in depth so that it comes to lock directly on the channel (4) The screw "butterfly" (14) allows the blocking of the jaw (11-12-13) The border (2) can as well be positioned on a bar (10) that on an amount of the scale (6) The jaw (1112-13) can enclose a branch if it is desired that the ladder (6) is positioned in a tree. In all cases the ladder is secured to its support and a removable jaw, not shown, can be replaced to adapt to its clamping point and on different scales.

Selon une variante, non illustrée, cette invention (1) pourra être aménagée de telle sorte que la mâchoire (11-12-13) puisse se bloquer sur des parties de 38 différentes formes ainsi que sur différentes configurations d'échelles.  According to a variant, not illustrated, this invention (1) can be arranged so that the jaw (11-12-13) can hang on parts of 38 different shapes and different scale configurations.
