CA 2747421

A hinge for cold rooms, swing gates or the like, which comprise a stationary support structure (S) and at least a door (A) movable between an open door position and a closed door position. The hinge comprises a box-like hinge body (3) and a pin (5) reciprocally rotatably coupled to rotate about a first axis (X) between the open door position and the closed door position. Closing means are provided (10) for automatically returning the door (A), as well as a working fluid acting thereon to hydraulically contrast their action. The closing means (10) comprise a cam element (11 ) unitary with said pin (5) interacting with a plunger element (12) housed in an operating chamber (25) defined within the box-like hinge body (3). The box-like hinge body (3) has an elongated shape to define a second axis (Y) perpendicular to the first one (X).

L'invention concerne une charnière pour chambres froides, barrières pivotantes ou similaires comprenant une structure de support fixe (S) et au moins une porte (A) mobile entre une position de porte ouverte et une position de porte fermée. La charnière comprend un corps de charnière du type boîte (3) et une tige (5) accouplés réciproquement de manière rotative pour tourner autour d'un premier axe (X) entre la position de porte ouverte et la position de porte fermée. Des moyens de fermeture (10) permettent de renvoyer automatiquement la porte (A), un fluide de travail agissant sur ces derniers afin de compenser leur action de manière hydraulique. Les moyens de fermeture (10) comprennent un élément came (11) qui est formé d'un seul tenant avec ladite tige (5) et interagit avec un élément plongeur (12) logé dans une chambre de commande (25) délimitée dans le corps de charnière du type boîte (3). Le corps de charnière du type boîte (3) présente une forme allongée de manière à définir un second axe (Y) perpendiculaire au premier (X).
