Definitions
- the present invention relates to a safety device ensuring the stability of ladders by intermediate attachment of the ladder to tubular or rectangular scaffolding structures or railings whatever their inclination .
- the device according to our invention therefore makes it possible to remedy these drawbacks because it is designed to secure the ladder to the stability of the structures scaffolding must be installed at least one meter above the floor so as to prevent any risk of workers falling.
- the device according to our invention attaches manually and without special tools to scaffolding structures or railing between the level of the floor and the upper part of the railing planned and implemented according to current safety standards.
- the device according to our invention can be used, due to its asymmetry, in all directions whatever the position and the inclination of the scale placed in relation to the structure and vice versa. Finally, when using the device according to our invention, its position in no way hinders the free passage of its users.
- EP-A-0 171 485 which allows parts of different shapes to be brought into contact.
- US-A-2,392,932 It describes an apparatus consisting of two clamps, one of which is intended to grip a section tube strictly circular, the other clamp ending in a hook. The connection between the two clamps do not allow adaptation to a ladder.
- GB 2,222,629 describes a ladder fixing device comprising two clamps joined by a joint. Tightening a clamp on the ladder blocks the joint. Clamping does not provide secure security.
- the device also comprises a brake adapted to the size of the screw head, so that the screw can be locked when the device is in the closed position.
- the device also comprises a butterfly screw (2) passing on either side of the scale acceptor (1) by a nut (5) used to manually block the amount of the scale (12) by pressing it between the end of the wing screw (2) and the walls of the scale acceptor (1).
- the third characteristic of the device is that it also comprises a cylindrical tube (6) through which the butterfly screw (2) passes; this cylindrical tube (6) connects the ladder acceptor (1) to a structure fastener (3) open at its ends for housing a screw (4), the latter being able to be moved between two positions corresponding to the open states and closed of the device according to our invention; the space defined by the structure fastener (3) and delimited by the screw (4) is used to insert the tubular or rectangular structure (10).
- the device comprises the structural fastener (3) composed of two different openings at the ends of its two opposite faces: one includes the head of the screw (4) whatever the position of the latter and the another retains the screw (4) only in the closed position by means of two angled hooks (9).
- the device has a wing nut (7) which is tightened manually around the screw (4) against the structure fastener (3) and encloses the tubular or rectangular structure (10) inside the fastener structure (3) which is then retained by the tubular or rectangular intermediate structure (14) or by the floor (11) depending on the height of use of the device according to our invention chosen by the worker.
- the device also comprises a brake (8), adapted to the size of the head of the screw (4), so as to be able to lock the screw (4) when the safety device is in the closed position.
- the device according to our invention is designed to adapt to all types ladders and tubular or rectangular structures (10). However, it is possible to adapt the entire device according to our invention to special dimensions without limitation.
- the device according to our invention is particularly intended for construction and public works workers.

Description
- un acceptant d'échelle 1 ouvert au moins sur trois de ses faces susceptibles de coulisser le long d'un montant de l'échelle 12 et de se fixer en un endroit approprié de celui-ci ;
- un tube cylindrique 6 astreint à pivoter autour de l'axe d'une vis papillon 2 de l'acceptant d'échelle,
- un attaché de structure 3 fixé au dit tube 6, délimitant entre ses parois latérales un espace permettant d'insérer un élément 10 tubulaire ou rectangulaire de l'échafaudage,
- la figure 1 est une vue en perspective d'un dispositif selon l'invention, en position fermée.
- la figure 2 est une vue en plan du même dispositif dans la même position avec la position ouverture représentée en pointillés, et
- la figure 3 représente en perspective une échelle fixée à un échafaudage par un dispositif selon l'invention.
Claims (2)
- Dispositif de sécurité pour échelle permettant de stabiliser celle-ci en la rendant solidaire des structures d'échafaudage, comportant trois éléments solidaires entre eux:un acceptant d'échelle (1) ouvert au moins sur trois de ses faces susceptibles de coulisser le long d'un montant de l'échelle (12) et de se fixer en un endroit approprié de celui-ci ;un tube cylindrique (6) astreint à pivoter autour de l'axe d'une vis papillon (2) de l'acceptant d'échelle,un attaché de structure (3) fixé au dit tube (6), délimitant entre ses parois latérales un espace permettant d'insérer un élément (10) tubulaire ou rectangulaire de l'échafaudage,
- Dispositif selon la revendication 1, caractérisé en ce qu'il comporte également un frein (8) adapté à la taille de la tête de la vis (4), de façon à pouvoir bloquer la vis (4) lorsque le dispositif est en position fermée.
