Patent

CA 2710751

A dock leveler (10) comprising a vehicle-engaging lip (20) pivotally coupled to the vertically adjustable front edge of a deck (18) includes a seal or series of seal segments that close one or more air gaps (36) that exist in the area where the lip is hinged to the deck. Such gaps are particularly large when the lip hinge comprises a hinge pin that couples a series of lugs (30) extending from underneath the deck to a series of lugs (32) extending from the lip, wherein the lugs are spaced apart along the length of the hinge pin (34). The seal or seal segments could be above the deck, below the deck, or interposed between the adjoining edges of the deck and the lip. In some cases, the seal is provided by an air curtain or by a tube that is inflatable or hermetically sealed.

L'invention porte sur un niveleur de quai (10) comprenant une lèvre de coopération avec un véhicule (20) couplée de manière pivotante au bord avant réglable verticalement d'une plate-forme (18) qui comprend un joint ou une série de segments de joint qui ferment un ou plusieurs espaces d'air (36) qui existent dans la zone où la lèvre est articulée à la plate-forme. Ces espaces sont particulièrement grands lorsque l'articulation à lèvre comprend une broche d'articulation qui couple une série de taquets (30) s'étendant du dessous de la plate-forme à une série de taquets (32) s'étendant à partir de la lèvre. Selon l'invention, les taquets sont espacés sur la longueur de la broche d'articulation (34). Le joint ou les segments de joint pourraient se trouver au-dessus de la plate-forme, au-dessous de la plate-forme, ou interposés entre les bords adjacents de la plate-forme et de la lèvre. Dans certains cas, le joint est fourni par un rideau d'air ou par un tube qui est gonflable ou scellé hermétiquement.
