Patent ID: 8662066

Claim:
A closure device associable with the opening of a cooking chamber of a trolley-type oven, the oven including a closure door associated with said chamber, for sealed closure of the cooking chamber in an absence of the trolley, said device comprising a closure element capable of being placed to close a portion of the opening of the chamber that is not engaged by the closure door, the portion of the opening being capable of permitting the closure of the door when the trolley is inserted into the cooking chamber, said closure element co-operating in a sealed manner with respective sections of gaskets arranged at said opening, for the sealed closure of the cooking chamber when the trolley is not inserted in said chamber, said closure element is secured to the door of the oven and is at least partially flexible, so that said closure element is displaceable between an operative state in which, in the absence of the trolley in the cooking chamber and following the closure of the door, said element remains set, in an unfolded configuration, against the portion of opening, in order to ensure the sealed closure thereof, and a non-operative state in which, with the trolley inserted in said chamber and following the closure of the door, said element is still received in an at least partly folded configuration, between the door and the trolley, without interfering with the sealed closure in a region of said portion.
