Description

Support mechanism for access platform in Coaches

Object of the invention

The present invention relates to a mechanism of support for coach access platform, whose obvious purpose is to establish a stable means of support for platforms when they are folded in rest position.

The object of the invention is to achieve a optimal stability and positioning of the applicable platform such as means of access by coaches, however allowing make the appropriate movements as well as the rest of the positions from the platform itself.

Background of the invention

The platforms used as access in coaches, are usually mounted in a box with respect to which they can fold and unfold, based on a car that slides and is guided in the inside of the box, so that the platform is relates to the car through a swing arm provided in each of the sides.

In addition, the platforms are complemented by a flip top that in its deployed position constitutes the platform access surface, and whose lid can occupy a resting or collapsed position at 0 °, a vertical position at 90 ° constituting a barrier, and the horizontal position at 180 ° determining the access surface.

The problem with this type of platforms is its difficult application in smaller vehicles to those presented by normal coaches, precisely because The available space is smaller. In addition, no means are known. appropriate to allow support and therefore the stable position of when the platform with its access cover is in a folded or collected position.

Description of the invention

The mechanism that is recommended is planned precisely to solve the problem raised above, mechanism whose purpose is to serve as support for the platform when it is folded, that is, collected in resting position, with the particularity that in the rest of platform positions and the movements to be performed by it  are interfered by the mechanism in question.

More specifically, the mechanism of the invention it is determined by two parts, one corresponding to the arm of tilt that relates the platform to the car in each side, and another corresponding to the access cover.

As for the part corresponding to the arm, it comprises a rocker, provided on the inner side of the arm and a fixed stop to it on which it is likely to support the rocker.

As for the part corresponding to the lid of access, it is constituted by a solidarity stop of a piece belonging to the lid itself and provided for in each of the ends thereof, in proximity to the axis of rotation thereof, whose but as you can obviously turn to one side or the other following the own rotation or tilting of the lid. Said top of the lid is formed by a protrusion of the referred piece that, depending on whether the lid is folded at 0 ° or vertical at 90 °, it travels a another touching or not with the rocker provided in the respective arm of tilting the platform, all in a way that when the rocker is picked up from its lower end allowing the platform to rise. When said is exceeded rocker, then it is placed horizontally again, getting your recovery to the original position by collaboration of a spring or by its own weight, depending on the weight distribution.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Preferred Embodiment of the Invention

As you can see in the referred figures, the mechanism of the invention is applicable to platforms (1) that they have a folding cover (2) for access, which is articulated according to the axis of rotation (3), being able to be placed in extended position or 180 ° deployed to determine the access surface of the platform. It can also be placed by tilting in a vertical position at 90 °, as seen in figures 1 and 3, as well as in folded or pick up position at 0 °, which corresponds to that of rest, as seen in figures 5 and 7.

The platform (1) is related to a car (4) which is sliding and is guided inside a box (5), whose relationship between platform (1) and carriage (4) is effected by a swing arm (6) on each side, allowing once the car has slipped outward, raise and lower the platform (1), as well as placing it facing the height of the box (5).

Well, from these characteristics, the support mechanism for the platform carried out in accordance with the object of the invention, is formed by a stop (7) that forms part of the cover (2) and by the combination of a rocker (8) and a stop (9) provided in the respective swing arm (6).

The stop (7) belongs to a piece (10) articulated on the cover (2), in correspondence with the end of each of its sides, specifically with the end where it is established the axis of rotation (3) of said cover (2).

For its part, the rocker (8) is mounted on the inner side of the arm (6), as well as the stop (9) on the which can influence such a rocker (8).

In this way a means of support is constituted stable for the platform (1) in the folded and rest position of this, as seen in figures 7 and 8, and specifically in the detail of figure 8 itself, where the rocker (8) is resting on the stop (7) of the cover (2) and the stop (9) of the arm (6), however allowing the other positions of the platform (1) are not interfered with by this mechanism, such as neither does it intervene in the different movements that it has to perform said platform to occupy the folding positions and deployed, and even the folding and unfolding movements of the cover (2).

Claims (3)

1. Support mechanism for coach access platforms, where the platform is related, on each side, with a tilting arm articulated to a sliding car guided in a box with respect to which it can be removed to allow folding and unfolding of the platform itself, complementing it with an access cover capable of occupying a 180 ° deployed position, corresponding to the access position itself, a folded or resting position superimposed on the platform, and a vertical position at 90 °, wherein the mechanism itself is provided so that the platform in its collection or folded position together with the lid remains stably supported without interfering in the movements to be performed by such platform to adopt other positions, characterized in that it is constituted from a stop provided on the cover and a stop combined with a rocker provided on the respective side arm that relates the platform itself rma with the respective sliding carriage. 2. Support mechanism for access platforms in coaches, according to claim 1, characterized in that the stop provided in the cover is constituted by a projection belonging to a piece articulated at an end points of the sides of said cover, in proximity to the axis of rotation of the same, so that depending on the folded or vertical position of said cover, the stop will make a route or another contacting or not with the rocker provided in the respective rocker arm that relates the platform with the sliding carriage. 3. Support mechanism for coach access platforms, according to previous claims, characterized in that the rocker arm is capable of being connected to a spring to recover its resting position.
