Description

Drive mechanism of the cover Coach access platforms.

Object of the invention

The present invention relates to a mechanism for operating the cover of access platforms in coaches, whose obvious purpose is to carry out the operation of lifting the corresponding cover based on the thrust it exerts the platform in its lifting and / or lowering tilt for be in the operational or inoperative position.

The object of the invention is to achieve some lid actuation means simply, efficiently and without constitute any obstacle to the folding of said lid towards the resting position, manually.

Background of the invention

Access platforms applied by coaches are related to a scrollable and guided car inside of a box, relating the platform and the car through a arm established on each side, that arm being tilting to be able to carry out the movements of the platform.

These types of platforms include a lid swingarm that can be positioned at 90 ° forming a barrier, or either be in the horizontal plane to allow access to the platform to the coach to which it is applied, when it is in an elevated position, and can also be placed in a collapsed or collected position superimposed on the platform.

That cover must remain at 90 ° when the platform is lowered, and when in its tilting it passes through the center, while when the upper plane is reached it should be placed horizontally, that is to say that it must be folded 180 ° from the rest or folded position to the use or deployed position, all this in such a way that the folded or resting position, which corresponds to that of 0 °, is achieved manually, without the mechanism affects said movement.

As already said, the platform is related to a sliding carriage guided inside of the box, relation that is made by a lateral arm that makes it possible to arrange said platform in a lowered position with the lid at 90 °, a position facing the box with the lid also at 90 °, and an elevated position in which the lid can be deployed to 180 ° to allow access, or fold to 0 ° and overlap by tilting the platform and occupy the position of repose.

When the platform is applied in vehicles of smaller size, there are problems when making the tilting the lid, due to lack of space among other reasons requiring a simple and economical system.

Description of the invention

The mechanism that is recommended is precisely a solution to the problem posed above, for which it has been foreseen that the tilting movements of the transit cover are carried out by pushing an axially sliding slider and arranged laterally, guided by a skate belonging to the same that slides in an elongated window made for this purpose on a support fixed laterally to the platform, at the same time guiding that slide through a side wheel emerging from said fixed support, and whose wheel travels in a torn window of the slide itself . In the description that is going to be made next, the elements of one side will be mentioned, although they are arranged in the same way in both
lateral.

For its part, the tilting box, in proximity to its axis of articulation, it is related to a side piece layered that in its push and tilt forces to tilt the lid, since the layered side piece is articulated on end of a connecting rod that at its other end articulates with a cam which in turn is articulated to the fixed lateral support to the platform.

In the joint between cam and connecting rod has provided a bearing to facilitate the movement.

In this way, when the tilt of the support arm to the platform to move (raise and / or lower) the same, you get simultaneously the axial displacement of the slide, as it is related to said arm through a plate with multiple positions of anchor between said plate and the articulating elements (arm and slide).

That linear displacement of the slide carries I get the thrust over the joint area between the connecting rod and the cam, and with it the thrust of these, so that based on that articulation occurs the swinging of said connecting rod-cam assembly and with it the tilting of the angled piece articulated laterally to the lid, producing consequently its tilting from the position horizontal or of use until reaching the vertical position at 90 °, to from which said lid can be folded to position a 0 °, that is to say superimposed on the platform, corresponding to the resting or folding position of said lid.

Once the position at 90 ° has been reached by the cover, even if the slide continues to move, can be maintained such a cover in that position at 90 ° and be folded manually, as commented previously.

The movement of the repeated cover can be regulate based on the multiple positions in which you can articulate the plate with respect to the arm and with respect to the slide side.

In short, the thrust of the mechanism is what brings the lid up from the horizontal position to the position vertical or 90 ° while in the movement of lowering the mechanism is only removed, so that the movement of the lid It is done thanks to its weight and a spring that pushes it.

Preferred Embodiment of the Invention

As you can see in the referred figures, the mechanism of the invention is applicable to platforms (1) equipped with a tilting cover (2) that can be placed superimposed on the platform (1) corresponding to the 0 ° position and therefore of folded or resting, being able to occupy a position vertical at 90 °, constituting a barrier when the platform (1), which is tiltable and movable, occupies a lowered position or confrontation with the corresponding car (3) with which it is related.

Said cover (2) can also occupy a 180 ° deployed position corresponding to that of access on the platform (1).

As for the car (3), it is mounted on guided form inside a box (4) with respect to which can be collected and / or extended to fold and / or unfold the platform (1), this being related to said car (3) by means of two swinging arms (5) provided in each side.

For its part, the cover (2) is mounted articulated on the platform (1), through an axis of rotation (6), in order to tilt or turn it in one or other sense.

Based on these characteristics, the mechanism of the invention is constituted, on each side, from a slide (7) mounted laterally to the platform (1), with faculty of linear displacement with respect to it, being endowed this slide (7) of an elongated window (8) on which it is guided a wheel (9) emerging laterally from a fixed and lateral support (10), with respect to which the slide (7) is movable in a way guided by the commented wheel (9) and by a skate (11) belonging to the slide itself (7) and sliding through the window torn (12) from the side and fixed support itself (10).

For its part, the cover (2) has laterally the articulation of a bent piece (13), in proximity to the axis of swing or tilt (6) of that, on whose angled piece (13) in turn articulates the end of a connecting rod (14), articulated in turn by the opposite end of a cam (15) articulated to the lateral and fixed support (10).

In correspondence with the articulation between connecting rod (14) and cam (15) a bearing (16) is provided that It facilitates the movement.

As for the linear displacement of the sliding (7), is achieved on the basis that it is related to the corresponding arm (5) by means of a plate (17) able to look at multiple positions both in respect of the slide (7) as of the arm (5), relating to it to through a support (18) that includes the multiple points of anchor of the plate itself (17); that is to say that the articulation of such a plate (17) to both one and another element, has multiple positions, as can be seen in figure 4, to be able to definitively regulate the movement of the access cover (2).

According to the exposed characteristics, from the unfolded position of the lid (2) at 180 ° as seen in Figures 2, 3, and 4, the tilting thereof until it is located at 90 °, as seen in figures 6 and 7, it is done by pushing on the set that form the connecting rod (14) and cam (15) and of these on the angled part (13), the thrust that the displacement performs linear that is produced by the slide (7) when tilts the arm (5) and therefore the platform (one). That linear displacement of the slide (7), properly guided as previously stated, brings with it that the end of the same incision and push on the joint area of the connecting rod (14) and cam (15), producing the tilting ascending of these and with it the push on the bent piece (13) which also tilts up, forcing the lid (2) swing upwards as seen in figure 5, until reach the vertical position at 90 ° of figures 6 and 7, from whose position the cover (2) is folded manually to the position of 0 ° collection, as seen in figure 8, collaborating on it own weight of it and a spring (not shown) that the Push.

The position at 90 ° of the cover (2) and abatement from this to the folded position, it can be maintained and performed regardless of whether the slide (7) can continue moving linearly.
