Abstract
A door system (1) includes a door leaf (3) for closing off an entrance opening (4) and a suspension rod (10) having two opposite ends (11, 12) supported by a support structure (13). A suspension member (14) connects the door leaf (3) to the suspension rod (10) and can slide together with the door leaf (3) along the suspension rod (10) from an initial position corresponding to a closed position of the door leaf (3), to a final position corresponding to an open position of the door leaf (3). The two opposite ends (11, 12) of the suspension rod (10) are slidable in a horizontal direction transverse to the entrance opening (4). The suspension member (14) is slidably coupled to and guided by a non-linear upper guide (17) positioned above the suspension rod (10).
Claims12
A door system for a passenger transport vehicle, comprising:
- A) a door leaf for closing off an entrance opening defined by at least a first doorpost and a second doorpost,
- B) a displacement system for supporting and moving the door leaf between:
- a closed position in which the door leaf is positioned in said entrance opening between the first doorpost and the second doorpost and a first side edge of the door leaf is adjacent to the first doorpost and a second side edge of the door leaf is adjacent to the second doorpost, and
- an open position in which the door leaf provides access to the entrance opening,
- wherein the displacement system comprises:
- a suspension rod having two opposite ends supported by a support structure in a first suspension point on a side of the first doorpost and in a second suspension point on a side of the second doorpost,
- a suspension member that connects the door leaf to the suspension rod and that slides together with the door leaf along the suspension rod between the first suspension point and the second suspension point,
- an actuator operable to translate the suspension member along the suspension rod from an initial position corresponding to the closed position of the door leaf, to a final position corresponding to the open position of the door leaf,
- C) a guide system configured to guide the door leaf from the closed position to the open position comprising:
- an initial phase of outward rotation of the door leaf in which the second side edge of the door leaf moves transversally away from the entrance opening and laterally beyond the second doorpost,
- a phase of lateral translation of the door leaf at least partially away from the entrance opening,
- a final phase of inward rotation of the door leaf opposite to the initial outward rotation,
- wherein each of said two opposite ends of the suspension rod is slidable in a substantially horizontal direction transverse to the entrance opening, and the suspension member is slidably coupled to and guided by a non-linear upper guide positioned above the suspension rod;
- wherein the upper guide is fixed with respect to the support structure and extends from a first side of the door system where the first door post is arranged to a second side of the door system where the second door post is arranged, thereby approximating towards the entrance opening and converging towards a plane substantially parallel to the entrance opening;
- and
- wherein the upper guide forms:
- an initial section on the first side that defines with the entrance opening an initial convergence angle,
- a final section on the second side that defines with the entrance opening a final convergence angle, and
- an intermediate section, between the initial section and the final section, that defines with the entrance opening an intermediate convergence angle,
- wherein the intermediate convergence angle is smaller than the initial convergence angle and the final convergence angle is smaller than the intermediate convergence angle.

- and
- wherein the lateral guides have an angular or “C” shape profile and are each engaged by a lateral guide roller of the ends of the suspension rod.
