Description

Access device for elevators.

Object of the invention

The present invention relates to a device that allows access to an elevator, whose door entrance is located in front of a slope. By saying device is allowed to install elevators in places where accessibility to them is very complicated, as per example; on stairs of buildings that do not have landings Suitable for access to an elevator.

The present invention therefore covers a scope of application in the installation of elevators that until the moment had not been covered, resulting in special interest in the field of rehabilitation and renovation of buildings.

Background of the invention

The state of the art closest to the present invention is within the scope of accessibility to transport vehicles, by people in wheelchairs or strollers for children. An example within this field of application It is shown in document ES2208538T3.

In this document you can see a built-in lifting device at the bottom of the door Vehicle access Said lifting device comprises a telescopic platform that protrudes completely from a frame of support fixed to the vehicle. The telescopic platform comprises its once some elements of union, in the form of parallelogram, articulated With the support frame. These joining elements allow leveling the platform with the exterior access surface and raise it subsequently until it is at the level of the onboard surface, leaving a gap between the latter surface and the one corresponding to the platform. So the telescopic platform also requires a sliding extension that finally allows access to vehicle, saving the aforementioned gap.

However, this device of certain mechanical complexity is unfeasible for application in elevators intended to be installed on stairs of buildings that they do not have the appropriate landings to access them, since that the components of said device have enormous difficulties of architectural integration.

It exists therefore in the field of rehabilitation and renovation of buildings an important area of application in the installation of elevators that so far It lacked a technical solution. The present invention allows to cover said scope of application by means of a practical device of access that allows to save an unevenness, such as stairs or a ramp, which is located in front of the door of an elevator.

Description of the invention

To solve the exposed problems formerly the access device for elevators, of the type of those that comprise a door arranged in front of a slope, understands:

?

a folding platform with a motorized pivot shaft integrated in the bottom of the elevator, where said platform is configured to adopt:

-

a upright position where the platform is folded over the door to allow free movement of people along the route defined by the slope; Y

-

a lying position where the platform is level with a delivery area to allow access to the elevator saving the unevenness;

Y;

?

power and control means which allow changing from the upright position to the lying position, and vice versa, warps controlled.

The feeding and control means comprise both the electrical protection switches and the equipment control and maneuver (relays, automatons, detectors, controls etc.) to the correct operation of the installation. In this sense, the feeding and control means comprise a first end of race arranged in the elevator, whose status is active or at rest causes interchangeably:

?

a closed door situation that keeps the platform in the upright position or that activates said platform to change from position to position upright Y

?

an open door situation that keeps the platform in the lying position or that activates said platform to change from the upright position to the position lying

Preferably, said first end of the race, consisting of any type of contact or micro detector commercially available switch and suitable for that purpose, it is arranged between the fixed part and the mobile part of the door, being able to detect if it is open or closed.

Additionally, the feeding means and control comprises one or more presence detectors located in the near the elevator, which in the wake of people cause:

?

motion inhibition of the platform during the change from the upright position to the position lying and retracting it until the upright position is adopted; or

?

platform activation to change from position to position upright

These presence detectors present safety functions, avoiding possible falls, bumps and trips with the platform, by the users of the stairs.

Additionally, the feeding and control means comprise elevator call means that activate the platform to change from the upright position to the lying position. Preferably, for greater security, said calling means are out of reach from the vicinity of the slope. The calling means may consist of push buttons, keyed drives or magnetic cards, among others. Its operation is coordinated with the presence detectors, to prioritize the function of one or the other according to the mode
wanted.

Additionally, the feeding means and control comprise an alarm (acoustic, visual or mixed) that is active with the movement of the platform.

In order to maximize the stability of the platform, the device comprises support means integrated in a wall opposite the elevator. On said means rests, during the lying position, the furthest end of the platform from the axis of rotation. Preferably, the support means comprise one or more guides fixed on the wall, arranged so that the platform fits perfectly both the contour of the wall and the contour of the delivery surface. Additionally, the feeding and control means comprise a second limit switch arranged on said support means, whose status in active or at rest checks interchangeably if the platform is in the laid position. Additionally, the power and control means comprise a third limit switch arranged at the rear of the axis of rotation to verify that the platform is in the upright position whose active or idle state independently checks whether the platform is in the upright position. These limit switches, consisting of any type of contact detector or micro switch, allow precisely stop the movement of the axis of rotation when the platform reaches a certain
position.

For security reasons, preferably the platform comprises a guardrail that is located folded over it during the upright and ready position on its opposite end to the delivery surface, where said guardrail is configured to:

?

unfold during the change of the upright position to the lying position until adopting a position perpendicular to the platform; Y

?

fall back on the platform during the change from position to position upright

Such actions can be carried out by electrical, mechanical, hydraulic means or combinations of themselves in coordination with the feeding and control means.
