Abstract
Abstract A folding door for the luggage compartment of vehicles comprises a pair of leafs pivotally interconnected to one another. The upper leaf is pivotally connected to the wall of the compartment, whereas the lower leaf is pivotally connected to the wall of the compartment. An actuating device is provided which is pivotally connected to the wall of the compartment at one end and also pivotally connected to a projecting arm projecting from the first leaf. The arrangement of pivotal connection of the leafs together with the actuator provides for a dead center position of the projecting arm of the first leaf. When the projecting arm is above the dead center position, the actuator acts on the projecting arm so as to close the leafs against the opening in the compartment. When the projecting arm is below the dead center position, the actuator acts to pull the projecting arm and thereby the first leaf away from the opening in the compartment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
284 words
A folding door for the luggage compartment of vehicles, said luggage compartment having a wall provided with an opening, said door comprising a first leaf having an edge and opposite end portions, means for pivotally connecting one of said end portions of the first leaf to said wall adjacent the opening, a second leaf having an edge and opposite end portions, means for pivotally connecting one of said end portions of the second leaf to the other end portion of the first leaf, a connecting rod including opposite end portions, means for pivotally connecting one end portion of the connecting rod to said wall, means for pivotally connecting the other end portion of the connecting rod to the other end portion of said edge of said second leaf, said first leaf including a projecting arm extending transversely thereto, biasing means including opposite end portions, means for pivotally and permanently connecting one end portion of said biasing means to said projecting arm at a position which, with the door closed, is above the first said means, and means for pivotally connecting the other end portion of said biasing means to said wall, said projecting arm having a dead center position defined by its position when the means pivotally connecting the biasing means to the projecting arm is co-linear with an imaginary line joining the means pivotally connecting the first leaf to the wall and the means pivotally connecting the biasing means to the wall, said biasing means acting on said projecting arm for urging said first leaf toward said opening when said projecting arm is above said dead center position and away from said opening when said projecting arm is below said dead center position.
Claim 2
Dependent Claim
284 words
A folding door for the luggage compartment of vehicles, said luggage compartment having a wall provided with an opening, said door comprising a first leaf having an edge and opposite end portions, means for pivotally connecting one of said end portions of the first leaf to said wall adjacent the opening, a second leaf having an edge and opposite end portions, means for pivotally connecting one of said end portions of the second leaf to the other end portion of the first leaf, a connecting rod including opposite end portions, means for pivotally connecting one end portion of the connecting rod to said wall, means for pivotally connecting the other end portion of the connecting rod to the other end portion of said edge of said second leaf, said first leaf including a projecting arm extending transversely thereto, biasing means including opposite end portions, means for pivotally and permanently connecting one end portion of said biasing means to said projecting arm at a position which, with the door closed, is above the first said means, and means for pivotally connecting the other end portion of said biasing means to said wall, said projecting arm having a dead center position defined by its position when the means pivotally connecting the biasing means to the projecting arm is co-linear with an imaginary line joining the means pivotally connecting the first leaf to the wall and the means pivotally connecting the biasing means to the wall, said biasing means acting on said projecting arm for urging said first leaf toward said opening when said projecting arm is above said dead center position and away from said opening when said projecting arm is below said dead center position.
Claim 3
Dependent Claim
15 words
A door as claimed in claim 1 wherein said biasing means includes a fluid actuator.
Claim 4
Dependent Claim
72 words
A folding door according to claim 1 wherein at least the means pivotally connecting the first leaf tO the wall provided with the door opening is constituted by an I-section band of strong, flexible material, the heads of which slide and are held in corresponding cavities in section bands fastened to the corresponding edges of the first leaf and of the door opening, in such a manner as to ensure tight closure.
