Definitions

the present invention relates to an apparatus for transporting disabled people on stairs and the like.
apparatuses for transporting disabled people on stairs and the like are generally constituted by a supporting frame slideable on guides which are associated with the fixed structure, to which a tilting platform is articulated.
At least one safety bar arranged on the descent side, which must be placed in a safety position when the apparatus is moving with a passenger and must be placed in a raised position in order to allow access and descent of the passenger.
the safety bar must further be arrangeable in a position of minimum space occupation when the apparatus travels without a passenger.
Patent IT 1279827 discloses an extremely practical and functional solution in which transition from the raised-bar position to the position of minimum space occupation is performed by way of a translation movement of the bar which, in practice, retracts into the volume of the frame, simply keeping the upper end spaced from the frame, so as to prevent any accidental crushing of anything interposed between the safety bar and the supporting frame.
the bar is connected to a truck slideable in two parallel guides which are formed by the frame and move mutually apart at the upper end so as to allow to tilt the safety bar toward the safety position.
the aim of the present invention is to achieve the above-noted advantages by providing an apparatus in which it is possible to further reduce the overall dimensions of the bar arranged in the position of minimum space occupation without however entailing any risk.
a particular object of the invention is to provide an apparatus in which the means for guiding the sliding of the bar are considerably simplified yet remaining highly functional.
Another object of the present invention is to provide an apparatus in which it is possible to minimize the number of components, further achieving considerable constructive simplifications.
Another object of the present invention is to provide an apparatus which can be easily obtained starting from commonly commercially available elements and materials and is also competitive from a merely economic point of view.
an apparatus for transporting disabled people on stairs and the like comprising a supporting frame which can slidingly engage guides which are connected to a fixed structure, a tilting platform for supporting the passenger and at least one safety bar being connected to said frame, said bar being movable from a raised position to allow passenger access and descent to a position of minimum space occupation in which it is adjacent to said supporting frame, characterized in that it comprises crush-prevention means of the bar which are adapted to provide an elastic yielding of said at least one safety bar if there is an obstacle between said at least one safety bar and said supporting frame.
the apparatus for transporting disabled people on stairs and the like comprises a supporting frame, generally designated by the reference numeral 1, which in a per se known manner can slidingly engage guides which are connected to a fixed structure.
a tilting platform 2 on which the passenger is accommodated is associated with the frame 1.
At least one safety bar 3 which is arranged on the descent side and can move with respect to the frame 1 so as to be arranged in a safety position, shown in Figures 3 and 4, in which the bar is arranged at the level of the passenger, and in a raised position, which frees the space to allow ascent and descent of the passenger.
the bar is arranged in a position of minimum space occupation, retracting in practice into the frame 1.
the bar 3 is slidingly guided in a vertical guide 10, formed by the side wall of the frame, by engagement with a first pivot 11 and a second pivot 12 which are mutually spaced and in practice allow the bar to retain its vertical position during its translation movement within the guide 10.
the upper portion of the guide 10, designated by the reference numeral 10a, is inclined approximately horizontally with respect to the vertical portion 10, so as to force the safety bar to rotate in order to be arranged in the safety position.
the bar is moved by means of an actuation chain 20 which runs between a lower pinion 21 and an upper pinion 22 and is actuated by an actuation pinion 23 driven by a motor 24 which is supported by a central plate 25 accommodated in the frame; the chain is coupled to the lower pivot 11.
the actuation pinion 23 engages the chain 20, moving it in both directions.
a particular characteristic of the invention is that there are crush prevention means of the bar, which in the position of minimum space occupation, can be arranged completely within the frame, further minimizing external space occupation.
the crush prevention means can provide an elastic yielding of the safety bar if an obstacle becomes interposed between the safety bar and the supporting frame.
the crush prevention means comprise a slider 30 which in practice joins the pivots 11 and 12 and which, in the lower portion of the vertical guide 10, engages an abutment constituted by a flexible bar 31.
the guide 10 at its lower end, is provided with a wider portion 10b which allows the pivots to oscillate, with consequent inclination of the safety bar, which moves away from the frame, preventing the occurrence of crushing or the like.
the abutment bar 31 is provided with elongated slots 32 in which fixed pivots can slide; there are also elastic elements 33 which elastically push the abutment bar 31 against the slider 30 and allow the elastic yielding of the bar, allowing it to tilt, when an obstacle becomes interposed.
microswitches In order to manage the movements of the bar in safety, there are three microswitches which control the corresponding positions. The microswitches must remain pressed in all the positions of the bar and must be released only in the position that they must control.
Another innovative aspect of the invention is the fact that there are emergency release means being constituted by an actuation rod or screw 41 which engages the supporting plate of the motor in order to allow its tilting, as shown in Figure 4, with consequent disengagement of the actuation pinion from the chain, allowing to complete the movement manually.
emergency release means being constituted by an actuation rod or screw 41 which engages the supporting plate of the motor in order to allow its tilting, as shown in Figure 4, with consequent disengagement of the actuation pinion from the chain, allowing to complete the movement manually.
the motor can be released with a very rapid operation.
the materials employed, as well as the dimensions and the contingent shapes may be any according to requirements.
