Definitions
- the present invention relates to a door for lifts and elevators.
- a known device comprises a first fixed component, associated with the frame of the doorway and acting as a supplier of energy for a second component which is associated with the door, movably therewith, and is provided with means for generating a plurality of signals (in particular a network of infrared rays which intersect each other so as to monitor the doorway zone) and communicates with the fixed component in order to activate, if necessary, stoppage of the movement of the door with subsequent reversal of the direction of movement.
- a first fixed component associated with the frame of the doorway and acting as a supplier of energy for a second component which is associated with the door, movably therewith, and is provided with means for generating a plurality of signals (in particular a network of infrared rays which intersect each other so as to monitor the doorway zone) and communicates with the fixed component in order to activate, if necessary, stoppage of the movement of the door with subsequent reversal of the direction of movement.
- the first and the second component are electrically connected together only when the door is in the completely closed or completely open condition, while in the other siutations the second component has its own independent energy supply which is sufficient to cover the travel of the door.
- the second component in fact, is provided with an energy storage cell of the chemical or capacitive type which supplies power to the signal generating means and is periodically recharged at the end-of-travel points where it is coupled to the first fixed component.
- Said safety device requires, however, the creation of a special longitudinal member for housing the infrared sensors/emitters, which is mounted on the outside of each door as a separate element.
- the object of the present invention is to eliminate the abovementioned drawbacks and provide an electronically sensitive door which incorporates directly the electronic anti- closing safety means without requiring the presence of the member and the box-shaped housing mentioned above. Said objects are fully achieved by the door according to the present invention, which is characterized by the contents of the claims indicated below and in particular by the fact that the door is formed so as to have seats which incorporate the electronic anti-closing safety means associated with the door itself, without the need for providing special members or additional box-shaped housings.
- the door comprises a plurality of sensors which are arranged in a first channel formed by the profile of the door; an electronic circuit for controlling said sensors, which is directly fixed to ribs reinforcing the door itself and connected by means of cables to the sensors; a connector connected to the electronic control circuit by means of cables and positioned in a second channel formed by the profile of the door.
- Said connector is coupled to a corresponding connector of a power supply device fastened to the fixed frame of the doorway, whenever the door reaches the end of its opening or closing travel movement.
- FIG. 1 and 2 show a front view of the door according to two different embodiments of the connections of the anti-closing safety device
- Figure 3 shows a cross-section along the line A-A of the door according to Figure 1 ;
- FIG. 4 shows a cross-section through the door, the same as that of Figure 3, according to a variation of embodiment which envisages a substantially symmetrical profile of the door.
- 1 denotes in its entirety a door for lift or elevator doorways, the profile 2 of which is configured so as to form a first channel 3 and a second channel
- the first channel 3 and the second channel 4 are positioned on the two opposite vertical longitudinal sides of the door and may be different from one another (as in the case of
- the first channel 3 houses internally a so-called light barrier, of the known type, consisting of a plurality of sensors which are arranged longitudinally inside the first channel 3 and schematically denoted by 6 and are designed to detect the presence of obstacles such as persons, objects or animals along the opening or closing path of the door, namely along the threshold of the doorway.
- a so-called light barrier of the known type, consisting of a plurality of sensors which are arranged longitudinally inside the first channel 3 and schematically denoted by 6 and are designed to detect the presence of obstacles such as persons, objects or animals along the opening or closing path of the door, namely along the threshold of the doorway.
- Said sensors are connected by means of cables 7 to an electronic circuit 8 for controlling and managing said sensors, which is in turn connected by means of cables 9 to a connector 10 which is located in an original manner inside the second channel 4 of the door, in accordance with that shown in Figure 1.
- the ribs 5 act as support and seat for the electronic circuit 8.
- the connector 10 is coupled to a corresponding connector 12 represented by a component fastened to the fixed frame of the door. 4
- This component which is also known, has the function of supplying power to the electronic circuit 8 and hence the sensors 8 whenever the door reaches the end of its opening or closing travel path in accordance with a known technique.
- the cables 9 connect the electronic circuit 8 directly to a power source associated with the fixed frame of the doorway or the cage.
- the original feature of the present door lies in the particular configuration thereof which allows the sensors 6 and the connector 10 and the electronic circuit 8 to be housed without requiring an additional member for the sensors or a special box-shaped housing for the electronic circuit 8.
