Abstract

The cam (6) has a manual drive shaft (7) and an off-centered revolution part (10), and is supported on a floor beam (5) of a wall bracket or ladder cleat (1). The part stops in a point on a hollow shaft (11) of a clevis (9), when in clamping position to indicate to user that post supports are blocked on the beam. The shaft is lifted to disengage the revolution part from the point to permit the support to move on the beam.

This patent describes a console including a vertical arm sliding on the horizontal crossbar of the console can be immobilized to the building elements by means a key through the yoke sliding arm.

Certificat d'addition FR A 2122666 - perfectionnement apporté aux dispositifs de protection du genre garde-corps. Cet additif décrit plusieurs dispositions d'immobilisation de potelet de garde-corps sur dalle de béton ou autre élément d'une construction. Une disposition d'immobilisation décrite est réalisée au moyen d'une clavette.Certificate of addition FR A 2122666 - improvement to the protection devices of the guardrail type. This additive describes several restraint provisions of railing post on concrete slab or other element of a construction. An immobilization provision described is achieved by means of a key.

Toutes les dispositions énoncées dans les brevets ci-dessus, soit ne permettent pas d'obtenir un positionnement précis des supports de potelets bloqués sur la traverse, soit obligent de la part de l'opérateur l'utilisation d'un outil marteau ou autre pièce de battage que ce soit au blocage ou au déblocage.All the provisions set out in the above patents, either do not allow precise positioning of the post supports blocked on the transom, either require the operator to use of a hammer or other threshing tool, whether release.

La présente invention permet un réglage, un blocage et un déblocage par excentrique des supports de potelets de garde-corps sur console murale ou taquet d'échelle ou autres à la position souhaitée sans outil et remédie donc aux inconvénients précités. A cette fin, le support de potelet de garde-corps coulissant sur la traverse de la console murale ou taquet d'échelle est pourvu d'une chape dans laquelle s'articule un excentrique équipé d'une tige pour prise de main. La position de l'excentrique est déterminée de manière précise afin qu'après serrage l'excentration maximale soit légèrement dépassée assurant ainsi une position stable dite de blocage. Le débattement de l'excentrique est limité par le fait de venir en butée sur une surface perpendiculaire à la surface de serrage.The present invention allows adjustment, blocking and unblocking by eccentric rail bracket posts on wall bracket or scale stopper or others at the desired position without tools and remedies therefore to the aforementioned disadvantages. To this end, the guardrail post support sliding on the crossbar of the wall bracket or ladder cleat is equipped with a screed in which is articulated an eccentric equipped with a stem for taking hold of hand. The position of the eccentric is determined specifies that after tightening the maximum eccentricity is slightly exceeded thus ensuring a stable position called blocking. The travel of the eccentric is limited by coming to a stop on a surface perpendicular to the clamping surface.

Ces dispositions autorisent donc le déplacement des supports coulissants de potelet et leur blocage à l'endroit souhaité sur la traverse support de plancher de la console murale ou du taquet d'échelle.These provisions therefore allow the sliding supports to be moved of post and their blocking at the desired place on the cross support floor of the wall console or ladder stopper.

Les éléments de plancher, bastaings ou autres peuvent être maintenus plaqués les uns contre les autres quelle que soit leur largeur tout en évitant les vides dangereux entre ceux-ci.Floor elements, bastaings or others can be maintained plated against each other regardless of their width while avoiding dangerous voids between them.

Ces mêmes dispositions autorisent de situer précisément le plancher à la distance que l'utilisateur désire sur la traverse support de plancher de la console murale ou taquet d'échelle.
