    Description

    Field of the Invention



    [0001] The present invention relates to a system for operating the opening and closing of doors in movable platforms pertaining to a universal and accessible transport system for people/goods.

    Background of the Invention



    [0002] In reference to the field of actuating transport systems for passengers/goods including closing doors in the passenger platform, the need for a solution that reduces the overall dimensions of the equipment and that protects the user during the path in dangerous situations such as possible falls and blows is detected.

    [0003] The most common transport systems having a platform for passengers on the market with closing means are vertical moving equipment such as elevators. These elevators use a door closing and opening system located both in the passenger car (car doors) and on the floor (floor doors), the operation of which is located in the upper part of the car and it has a telescopic horizontal movement that increases its constructive dimensions since it requires space in the side part in order to open the doors.

    [0004] A need to find an improved movable car closing system which allows increasing the possibilities of the movement of the different cars in these systems for allowing new movement trajectories without limiting them to vertical movement trajectories of elevators and which in turn allow improvements in terms of the overall dimensions of the equipment which entail reduced construction work is detected.

    [0005] WO 00/07922 A1, EP 0 650 918 A2, DE 202 01 676 U1 and JP 52 103568 U all disclose a closing system for movable transport platforms according to the preamble of claim 1.

    Description of the Invention



    [0006] The present invention relates to a system for closing and opening doors in a platform pertaining to a system for the transport of people/goods, with the fundamental feature that the opening/closing movement is performed following a curved trajectory. Therefore, the invention relates to a closing system for movable platforms as defined in the set of claims.

    [0007] The system comprises drive means, which comprise a rack and pinion system moving the door which is supported on a set of support wheels on a V-shaped guiding which provides rigidity to the door and geometrically determine the trajectory of the closing/opening movement of the door. Once closed, the doors project over the floor of the platform, preventing having to make a slot in the floor, as occurs with current doors with mechanism located in the lower part. The distance between the floor and the lower part of the projecting door in the closed position is in accordance with the parameters indicated in the regulations in force on transport systems and goods for preventing trapping.

    [0008] An aspect of the invention relates to a closing system for movable platforms as defined in the set of claims.

    Brief Description of the Drawings



    [0009] A series of drawings which aid in better understanding the two proposals of the invention and which are expressly related to the embodiment of said invention presented as a non-limiting embodiment thereof is very briefly described below.

    Figure 1 shows a perspective view of the system of the invention.

    Figure 2 shows a perspective view of one of the support and drive columns.

    Figure 3 shows a detailed view of the support and drive column.

    Figure 4 shows a perspective view of the support column.

    Figure 5 shows a perspective view of the door of the system.


    Description of Preferred Embodiments of the Invention



    [0010] The system described in detail below.

    [0011] The system comprises two clearly distinguished areas; on one hand there is the door (1) itself which has an inner structure (10) providing it with rigidity and on which the V-shaped guides (4) and the lower rack (5) are secured. The V-shaped guides (4) are located: two in the upper part and two in the lower part, and the rack (5), is located in the lower part and in the area outside the passenger area, such that the rack (5) and, therefore, the drive system are not within reach of the user. At the same time, there will be a coating which covers the structure of the door and serves as an element providing comfort to the user and an aesthetic appearance to the platform. The second element forming the system is formed by the support columns (2, 3), which are fixed to the structure of the platform (15). These support columns (2, 3) can be tubular elements for reducing the weight of the assembly. The height-adjustable supports (6) for the support wheels (7) are located on these columns. The V-shaped guides (4) slide on these support wheels (7) and will provide the rolling path of the door (1), since the profile of these support wheels (7) copies the profile of the guide (4) and, therefore, the support wheels (7) have a V-shaped rolling profile. The shape of the V-shaped profile of the support wheels (7) conjugated with the V-shaped guide (4) allows a more guided rolling. Each support column (2, 3), one on each side of the structure of the door (10), will have 4 support wheels (7) distributed as follows, two in the upper part and two in the lower part, whereby providing great stability to the closing/opening movement of the door (1). On the other hand, said support wheels (7) are assembled on height-adjustable supports (6) which are adjusted in height in order to align and fix the support wheels (7) against the V-shaped guides (4) and to allow a precise adjustment of the assembly of the door (1) to prevent vibrations in the closing/opening movement of the door (1). These height-adjustable supports (6) are fixed to the support columns (2, 3). One of the two support columns is referred to as support and drive column (2), since the part of the drive system made up of a pinion (9) operated by a gear motor (8) is assembled therein. The rotating movement of the pinion (9) allows the rack (5) assembled on the door (1) to be moved following the trajectory of the V-shaped guides (4) and performing the closing and opening movements of the door. The gear motor (8) and pinion (9) assembly is fixed in the inner part of the support and drive column (2) and distanced from the useful passenger area such that it is inaccessible for the passenger.
