" OPENING DEVICE & DOOR CLOSURE " DESCRIPTION 5 10 16

OBJECT OF THE INVENTION The present invention relates to an opening device e. door closers, designed primarily for their application on carriage doors or. railway wagons, being of the type those operated at a distance from a plant or by means of a control button placed near said doors. The device is based on a minimum number of parts and on a functional simplicity that give it a mechanical simplicity without this implying a loss with respect to its operative reliability.

BACKGROUND OF THE INVENTION

The doors of train carriages and the like which are actuated in the distance by the train driver or head of the cabin, or which are actuated by the users themselves on the basis of an existing button in the vicinity of the doors themselves, are based on complex mechanisms which, despite their remarkable reliability, have the disadvantage of their high costs and constant maintenance in terms of their inspection and mechanical control. 25 Moreover, in the event of a possible breakdown, the replacement or replacement of parts takes considerable time due to the complexity of the mechanism in question.

DISCLOSURE OF THE INVENTION The device according to the invention, by which it is possible to open and / or close the doors of railway wagons or coaches and the like, has been designed to solve this problem in a fully satisfactory manner, providing a structure extremely simple with respect to the general mechanics of the pre-operative device. · W / Οβ

S 20 25 30 65.543 7 / in order to give the assembly the maximum operational reliability with a minimum of optional parts, which will not only result in a low maintenance cost, but also a very low manufacturing cost. economic savings for the companies that have numerous trains running daily. More particularly, the device is based on a threaded or worm spindle with two counter-pitch sections, each corresponding. one of the sections one of the two doors forming the assembly or pair of doors of an opening in this type of train carriages. These two threaded spindle portions each incorporate a nut which is attached to the respective door, with the particularity that one of said nuts forms part of an arm connected to the rod of a pneumatic cylinder whose drive will cause rotation of the spindle, and , therefore, the displacement of both nuts and, with them, the displacement of the doors to which they are connected by opening them, or their closure if the drive is carried out in the opposite direction. At the beginning of the opening, there is a movement of the doors outwards, and then an opposite and lateral displacement thereof, counting, for this purpose, with rollers located in upper guides, with a first diverging section outwards and a section (remainder ) parallel to the plane of the door, so that a first displacement of each of the doors towards the outside is followed, as it were said, followed by a lateral displacement in the opposite direction thereof to carry out the opening, and movement counterclockwise to close. It is not necessary to specify that the actuation of the pneumatic cylinder will be effected from any conventional system, and that the displacement of the corresponding rod would, as it were, imply the rotation of the spindle and hence the displacement of the nuts, since the two threaded spindle sections in the opposite direction and connected to the paths of the associated nuts to the corresponding ports. As can be seen, the device is based on a tremendously simple mechanism, practically free of any type of failure, since it is based on a spindle and two nuts, as well as the connection of one of the nuts to the piston of a pneumatic cylinder of action- It is obvious that these components, for their simplicity, are 3 35 65 543 m /

To complement the description we are making, and in order to help one. the present specification is attached as an integral part thereof by a single sheet of planes in which, in an illustrative and non-limiting manner, there is shown a general perspective view of the opening device and closure of doors for train carriages and the like, being logically represented in correspondence with the upper part of a pair of sheets forming a door, these sheets being displaceable in a lateral direction.

PREFERRED EMBODIMENT OF THE INVENTION

In view of said figure, it can be seen how the device of the invention is applicable to the opening and closing of the two sheets (1 'and 1') of a conventional door which are operable simultaneously both in their opening and in their closure, fundamentally for your application in train carriages. The device is based on a threaded spindle formed by two equal sections, (2) and (2 '), but with opposite thread pitch, each provided in correspondence with the upper part of each blade (1) '), respectively. These sections (2) and (2 ') of the spindle are screwed into the respective threads (3) and (3'), these being logically antagonistic to one another, each being attached to one of the sheets forming the door itself. On the other hand, the nut 3 is integral with an arm 4 which receives the rod 5 of a pneumatic cylinder 6 which at its other end has an anchoring tongue 7, with the particularity that the door leaf 1 is associated with a roller 8 or 8 'which slides through a chute 9 or 9' to drive the movement of the sheet 1 and 1 'respectively of the opening of the door, the movement of which in the opening is initially outwards, as a consequence of the rails (9) and (9 ') 4 35 1 1 5 10

That is, when the pneumatic cylinder 6 is actuated in the position corresponding to the closed door shown in the figure, the corresponding rod 5 will cause the nut 3 to rotate the spindle so that the section 2 will rotate in a (2 ') will rotate in the opposite direction, which will cause the nuts (3) and (3T) to move in opposite directions, and therefore, the movement of the sheets (1) and (1 *) in the direction lateral direction, the opening being made after the start of the outward movement, as previously stated.

In this simple and effective way, the problem of the complex mechanisms used in the doors of carriages and wagons is solved, without prejudice to the maximum effectiveness with respect to functionality and operational reliability. It is not considered necessary to take this description further. that any expert in the matter understands the scope of this aid and the benefits derived therefrom.

The materials, shape, size and arrangement of the elements are susceptible to variation as long as this change does not imply a change in the essence of the invention.

The terms in which this memory was described should be taken in a broad sense and not a limitation. 25
