Abstract
A bridge 4 comprises a floor 6 movable between a passive position (Fig 1), in which it allows pedestrian access to a flight of steps 2, and an active position (Fig 2), in which it is capable of bridging between a mobile platform 17 and a landing 1 at the top of the flight of steps 2.
Description
Access Apparatus This invention relates to apparatus for providing access
to a landing at the top of a flight of steps.
Disabled people experience difficulty in negotiating flights of steps. Such people may find it difficult, painful, or impossible to climb steps and may, in particular, be confined to wheelchairs.
Stair lifts are available capable of carrying a wheelchair up a staircase, but the use of such a stair lift is precluded if the width of the staircase is restricted, which is typically the case with a low-rise flight of steps leading to the front or side door of a dwelling.
What is desired is apparatus which allows access to a landing by both able- bodied and disabled people.
The present invention provides apparatus for providing access to a landing at the top of a flight of steps, the apparatus comprising a bridge which comprises a floor movable between a passive position, in which it allows pedestrian access to the steps, and an active position, in which it is capable of bridging between the landing and a mobile platform.
The invention will be described further, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a fragmentary perspective view of apparatus for providing access to a landing; Figure 2 is a view similar to Figure I, showing the apparatus in another position; and Figure 3 is a diagrammatic side view of the apparatus, showing the progressive steps in transferring a wheelchair from ground level to landing level.
The apparatus illustrated in Figures I to 3 allows access selectively by a wheelchair and by a pedestrian to a landing I at the top of a flight of steps 2 rising, for example 1 metro, from ground level 3. The apparatus comprises a bridge 4 including a floor 6 which is movable between a passive position (shown in Figure 1), in which it allows pedestrian access to the steps 2, and an active position (shown in Figure 2).
The floor 6 comprises two flooring sections 6a,6b, which are pivotably mounted on respective lateral frames 7a,7b so as to be laterally movable between the passive and active positions, as indicated by the arrow 8 in Figure 1. Each lateral frame has a rear leg 9a mounted at an upper part of the flight of steps and a front leg 9b mounted at a lower part of the flight of steps. In the embodiment illustrated, the lower ends of the rear and front legs 9a,9b are connected (e.g. by bolting or welding to plates 11 a,1 lb fixed to the landing I and the ground level 3 respectively. To allow for use with landings of difference heights, me front legs 9 are telescopic so as to be adjustable in length. (Alternatively, or additionally the rear legs 9a could be telescopic).
Each flooring section 6a,6b carries a supporting leg 12 which hangs from it and which has a telescopically adjustable foot 13 which rests on one of the steps 2 to support the flooring section 6a,6b in the active position, while the rear end of me flooring section rests on the landing 1. The leg 12 is connected to the flooring section 6a,6b and the associated lateral frame 7a,7b by a parallelogram mechanism 14 for controlling the movement of the supporting leg 12.
The bridge 4 is used in conjunction with an elevator 16 including a platform 17 which is movable in a vertical direction between a lower position (shown in Figure 1), in which it is substantially at ground level, and an upper position (shown in Figure 2), in which it is substantially at the same level as the landing I and the floor 6 in the active position. The platform is moved by any convenient lifting mechanism (for example a winch or an hydraulic ram). The platform 17 has two side frames 1 8a, 1 8b and is guided in its vertical motion by corner posts 19 at the front ends of fixed side walls 21 for preventing animals and children from entering the space under the raised platform 17.
For the same purpose, the front and rear ends of the space are covered by flexible blinds 22.
A hinged ramp 23 is provided at the front edge of the platform 17, to allow a wheelchair 24 to be moved onto the platform easily from ground level. As the platform begins to rise, the ramp 23 tilts upwards to form a stop for the rear wheels of the wheelchair, as shown in Figure 2. The elevator 16 also includes a wheel stop 26 at the rear end of the platform 17. The stop 26 is initially held upright by a flange 27 on one or both of the front legs 9b, until the platform 17 approaches its upper position, whereupon the stop 26 falls over the upper end of the flange 27 and forms a ramp between the platform 17 and the floor 6 in its active position, as shown in Figure 2.
The bridge 4 includes a mechanism for moving the floor 6 from the passive position (Figure 1) to the active position (Figure 2) automatically in response to arrival of the platform 17 at its upper position. In the embodiment illustrated, this mechanism comprises lever arms 28 which pivot with the flooring sections 6a,6b and which are engaged by abutments on the side frames 1 8a, 1 8b as the platform 17 approaches its upper position, so that the lever arms 28 drive the flooring sections 6a,6b towards their active position. When the platform is lowered to its lower position, the floor 6 may be returned to its passive position manually or by springs (not shown).
The progressive steps in transferring a wheelchair from ground level 3 to the landing 1 are shown in Figure 3. The user rides the wheelchair 24 onto the platform 17 at its lower position, from ground level 3, and then activates the lifting mechanism of the elevator 16 to cause the platform 17 to rise to its upper position, substantially level with the landing 1. During this process, the floor 6 is automatically moved from its passive position to its active position. The user can then ride the wheelchair 24 across the floor 6 and onto the landing 1. Subsequently, the user can return across the floor 6 to the platform 17 in its upper position and then operate the elevator 16 to cause the platform 17 to descend to the lower position, whereupon the user can ride the wheelchair 24 out of the elevator 16.
It will be appreciated that, when the platform 17 is in its lower position and the floor 6 is in its passive position, the flight of steps 2 is free for access by pedestrians.
Various modifications may be made in the apparatus. For example, the mechanism using lever arms 28 may be replaced by another mechanism which pivots the flooring sections 6a and 6b in dependence on the rising and falling of the platform 17. Such a mechanism may, for example, comprise cables and pulleys. Alternatively, if an hydraulic lifting mechanism is used in the elevator 16, a linked hydraulic actuating mechanism may be incorporated in the bridge 4 to move the floor 6 between the passive and active positions. Alternatively, the bridge 4 could incorporate one or more electric motors for driving the floor 6 between its active and passive positions, the motor or motors being under a control of a sensor which detects the presence of the platform 17.
The two flooring sections 6a, 6b could be replaced by a single flooring section pivotably mounted on a single lateral frame. The movement of the floor sections is not limited to simple pivoting movement about a fixed axis, but could be any convenient movement capable of moving the flooring sections between a passive position allowing pedestrian access to the steps and an active position bridging between the landing I and the platform 17 in its upper position. s
