Definitions

the present invention relates to an elevator system having an improved mechanism for locking and releasing a lock of a hoistway door and is particularly useful in systems in which the car and hoistway doors have aligned panels.
the present invention proposes a mechanism that solves all the above-cited problems, and provides an elevator system comprising an elevator car arranged to move in a hoistway, a door on said car, and a door on said hoistway, said hoistway door having a lock for holding it in a closed position, and a lock operating member, actuable to release said lock, said car door being provided with a pair of generally parallel, vertically elongate members and an actuating means operable to move said elongate members towards one another when said car door is closed and to move said elongate members apart when said car door opens, said elongate members being arranged when moved apart to engage with respective projections on said hoistway door, and to actuate said operating member to release said lock.
the elongate members In operation, when the car door is closed, the elongate members are positioned close to one another so that the car can move freely in the hoistway with the elongate members passing between the hoistway door projections. However, when the car stops adjacent a hoistway door and the car door begins to open, the elongate members move apart and operate to release the hoistway door lock and transmit the movement of the car door to the projections of the hoistway door so that the hoistway door and car door can move together.
the mechanism is based on a simple structure, with a high guarantee of reliability, which eliminates clearances and noise, and provides for more gentle movements.
Figure 1 shows a lock 1 comprising a latch plate 1b and a latch arm 1a.
the latch plate 1b is mounted on the hoistway frame door and the latch arm 1a is mounted on the hoistway door 5 at pivot point A.
a roller 7 is mounted on the latch arm 1a and is connected, by a spring 12, to a roller 6 mounted on the hoistway door.
a pair of parallel profiles 3 are connected together at their top and bottom ends by link members 12, which are pivotally connected to the car door 4 at pivot points P3.
a spring 10 is connected between the points P2 of the two link members 12 and a cam roller 8 is mounted on one of the pivot pins at point P1.
This cam roller 8 follows a cam track 9 mounted on a part 13 of the car, when the car door 4 closes.
the lock 1 is associated with a switch 2 and cooperates with the mechanism of Fig. 2, which is formed as a deformable parallelogram by tne two identical profiles 3 and the link members 12.
the above cited profiles 3 cooperate, in use, with the lock 1, through the rollers 6 and 7 which, as said, are connected to the hoistway door 5 and the latch arm 1a respectively.
the rollers 6 and 7 are arranged either side of the profiles 3 and face the vertical webs of the same, in such a way that, at the beginning of the opening of the car door 4 and in a corresponding displacement of the profiles 3, the webs of the profiles 3 can contact with and push the rollers 6 and 7, which in turn cause the lock 1 to tilt, as is shown in Figure 4, thus releasing the hoistway door 5.
roller 7 is connected to roller 6 by means of the spring 12.
roller 7 When roller 7 is pushed sideways by its corresponding profile 3, it causes latch arm 1a to tilt about an axis A positioned below it, thus releasing the lock 1.
the displacement of the profiles 3 is carried out by means of the cam roller 8 following the cam track 9.
the track 9 has a special shape made for this purpose, and is formed in a part 13 fixed to the car.
the track 9 is represented by a chain line in Figures 2 and 3.
the profiles 3 have flanges 11 which are pivotally connected to each other at points P1 and P2 by top and bottom link members 12. Both link members 12, and through them the profiles 3, are pivotally mounted to the car door at the points P3 located between the points P1 and P2.
the spring 10 is connected between the points P2 so that the link members 12 are biassed to move in a clockwise direction (as seen in Fig. 2) about the points P3, thereby tending to force the profiles 3 apart.
the cam roller 8 is connected to one of the link members 12 at point P1.
the parallelogram remains in its expanded form during the opening and re-closing of the car door 4 so as to transmit the movement of the car door 4 to the hoistway door 5.
a stop (not shown) prevents the spring 10 from rotating the link members 12 past their horizontal positions, at which the parallelogram is fully expanded.
the track 9 can be so shaped that the profiles 3 engage the rollers 6 and 7 at an appropriate rate.
the hoistway door 5 can move freely with the car door 4, in such a way that in the movement of the profiles 3 and of the cam roller 8, the initial movement of the car door 4 will be followed by the hoistway door 5, and both edges will be aligned, as when the doors are closed or totally open.
the lock 1 and rollers 6 and 7 will be provided on the hoistway doors 5 of each floor served by the lift, and the profiles 3 will move between these rollers 6 and 7 as the lift travels up and down between the floors.
the webs of the profiles 3 can be of an appropriate vertical length such that the profiles 3 can still cooperate with the rollers 6 and 7 even if the car and the floor at which it stops are slightly misaligned.
the opening and closing mechanism permits, in any position, the edges of the panels of the car door 4 and hoistway door 5 to be permanently aligned, therefore making it possible to simplify the car door stile as well as the hoistway door stile.
the lock need not be opened by the same members (in this case the rollers 6 and 7) as those with which the profiles 3 connect.
a button or other switch could, for example, be actuated by one of the profiles.
