ACCOMMODATION AND LOCKING DEVICE

The present invention relates to a retractor as defined in the preamble of claim 1 and a locking device as defined in the preamble of claim 5.

In elevators with an automatic door, the connection between the car door and the plane door is generally made by an attendant attached to the car door, which engages the counter members in the plane door by its engaging means. The receiver and counter members are arranged relative to each other such that as the elevator car passes past the plane door, the engaging means and counter door counter members in the embosser pass intermittently. With the basket level and the doors moving, the entrant 15 is caught in the counter members. Thus, the platform door also moves when the car door is moved by a power unit connected to the car door. Often, the gripping members are tin plates facing the level door from the retractor, forming a vertical groove that is open towards the level door. 20 Counter elements are often rollers in the level door which extend from the door towards the shaft and whose axis is perpendicular to the plane of the door. In connection with the receiver or the car door there is otherwise a locking device which closes the car door so that the car door can not be opened, at least without special measures, except when the car is close to the floor level, i.e. the car is in the door area. Locking the elevator door requires reliability and durability. Locking the elevator door should not generate annoying noises.

There are various arrangements for locking the elevator door in a reliable and elevator-friendly manner. For example, locking by a separate electromechanical actuator requires a separate subsystem or parallel system for controlling the operation of the elevator door, which performs the locking and unlocking of the door. Locking with a separate electromechanical actuator always causes an additional cost of the actuator in the system.

There are also mechanically operated locking devices, 2,102,673, in which the driving force for locking the door is taken from the movement of the elevator car or the movement of the car door. These have a separate slide in the elevator shaft at each floor level or another separate sign attached to the elevator shaft to indicate the level area and / or to control the operation of the lock. Installing such slides or signs in the shaft at each floor level required a great deal of installation time. Plenty of installation time means high salary costs.

10 Frequently, the car door lock arrangement is bulky, and the elevator car door or door hanger has to be designed to some extent with the location of the locking devices.

The need to achieve a simple, mechanically operable elevator car door locking device that is inexpensive to manufacture, inexpensive to use in space, easy to install, quiet in operation, and associated with an attendant is an invention of the novel inclusion and new elevator car locking apparatus. The incorporator according to the invention is characterized by what is stated in the characterizing part of claim 1 and the locking device according to the invention is characterized by what is described in the characterizing part of claim 5. Other embodiments of the invention are characterized in what is set forth in the other claims.

Advantages can be achieved with the invention e.g. as follows: The locking device is advantageously manufactured.

The locking device connected to the receiver simplifies 30 door concepts. Integration of the host and locking system simplifies the installation process.

-because the locking is controlled by the action of the catcher, i.e. whether the catching member of the catcher is within reach of the leveling door, the elevator shaft does not require separate control devices or signs to indicate the door area.

The locking device has a small space requirement, so it is not difficult to place it even in thin structures.

3 The 102673 locking device is easy to install near the door and requires no separate electrical controls when operated mechanically.

-the door remains locked outside the floor areas, any interference with the elevator's electrical system will not affect the 5 interlocks.

- if the elevator has stopped between floor levels in the event of a power failure, the door will open when the elevator is manually moved to the floor level.

hardware does not create extra noise when the elevator is moving or when locking or unlocking the 10 car doors.

locking and unlocking of the elevator car body door is temporally and hardwareally related to the opening and closing of the door.

The invention will now be described in more detail with reference to one embodiment of the present invention, with reference to the accompanying drawings, in which Figures 1 and 2 illustrate an inventive applicator with locking devices outside the level region;

In the following, parts are named using the terms left, right, upper, lower, etc. These terms refer to the 25 directions in the figures, as well as the expressions anticlockwise and clockwise.

With reference to Figures 1-4, an inventive applicator 4 with locks and its operation are described. Figures 1 and 2 illustrate a situation in which the elevator car is out of the level area, whereby the dampers 14 and 15 of the entrant 30 cannot hit the rollers which are counter-elements in any of the level doors. Figures 3 and 4 illustrate a situation where the elevator car is in the level area whereby when the doors are opened, the dampers 14,15 engage the rollers 17,18 in the level door. The carrier door hanging plate 1 has an assembly 4 assembled.

35 The car door hanging plate 1 has support rollers, and usually also counter rollers, which rolls correspond to a guide rail in the upper carrier beam supported by the elevator car or other suitable guide surface in the 4 102673 upper carrier beam. Thus, the door hangs in the upper support beam supported by the hanging plate or plates. The receiving dampers 14 and 15, between which the level door rollers 17 and 18 (shown in Fig. 4) enter when the access door 5 engages the level door, are secured to the lever 2 which is moved by the platform door actuator. The link 2 also engages a locking catch 10 for locking the car door. The locking catch engages a non-movable stop relative to the elevator car, for example, in the upper support beam of the door, or possibly a hinged door half 10. The basket door actuator opens and closes the basket door. Likewise, it opens and closes the level door which is connected to the basket door via the attendant. The actuator is, for example, a rope traction arranged to influence the direction of the door closing and opening movement and secured to the 15 catcher 4. The actuator may be a drive device other than a rope pull that provides substantially propulsive driving force, e.g. The doors are actually moved with the help of an attendant. The rope pull engages the lever 2 at the attachment point 3 of the operating lever 5. As a result of the rope 20 pull, the operating lever 5 tends to rotate with respect to the retractor 4 (and the retaining plate 1 on the retractor) around the stationary pivot point 6. The drive lever 5 is secured to the hanging plate 1 at the pivot point 6. The movement of the drive lever 5 relative to the pivot point 25 6 causes the proper movement of the lock 10 as well as the dampers 14 and 15 via the lever 2. The appropriate movement depends on whether the elevator is in the door area or not. Being in the door area is identified by the presence of leveling rollers in the gutter between the dampers 14 and 15. Thus, the height of the bar between the sheets 14 30 and 15 should be substantially the same as the height of the door area.

In figure 1, the arrows close and open are marked from the point of attachment 3. The close arrow indicates the direction (to the left in the picture) to which the cable pull will pull when the door is closed, and the open arrow to indicate the direction (to the right in the figure) to which the cable to pull when the door is opened. The close arrow also indicates the door closing direction and the 5 102673 open arrow indicates the door opening direction. In Figure 1, a sector 6a is shown on the pivot point 6 to illustrate an angle whose operating lever 5 rotates clockwise with respect to the pivot point 6 when an attempt is made to open the door by a cable pull.

The rotation caused by the pivoting of the operating lever 5 of some other parts of the link 7,8,9 is illustrated by the sectors 7a, 8a, 9a drawn on these. The linkage parts 7,8,9 are pivoted relative to the integrator relative to the stationary pivot points 7b, 8b, 9b. These pivot points 7b, 8b, 9b, which are stationary with respect to the integrator 10, are indicated in the figures by a solid (black) circle. Other joints and attachment points that are immobile with respect to the attachment are indicated by solid circles. The pivot points and attachment points that move with the joints are marked with an open 15 (white) circle on the inside. Fig. 2 shows the positions of the parts of the linkage 2, the dampers 14 and 15, and the lock 10, where they are positioned by the movement of the control lever via the linkage 2.

The following describes how the movement effect of the rotation of the operating lever 5 in accordance with sector 6a is propagated by the linkage 2. The operating lever 5 joins the linkage at three movable pivot points, namely 5x, 5y and 5z. Below the operating lever 5 is a support lever 21, which is pivotally attached to the stationary pivot points 21a and has movable pivot points 21x and 21y. The pivot arms between the pivot points 21a and 21x and between the 6 and 5x are equally long. Similarly, the pivot arms between the pivot points 21a and 21y and between the 6 and 5y are equally long. The left damper 14 engages the operating lever 5 and 30 on the supporting lever 21 at the pivot points 5x and 21x. At the pivot points 5y and 21y, the drive lever 5 and the "support lever 21" engage the synchronization bar 16 such that the pivot points 5x, 21x, 5y and 21y form angular points, with the left flap 14 and the synchronization bar 16 intersected and pivoting between the pivot points and the pivot arms between the pivot points 21a and 21y and between the 6 and 5y are parallel. It could even be said that the synchronization bar 102673 6 16, by its movements, corresponds to a damper and slide lock using a damper and lock similar to a conventional catcher 15 and is a detachable surface structure of the synchronization bar 16 which detaches from the immediate proximity 5 of the synchronization bar. At the pivot point 5z, a first rod 22 is connected to the operating lever 5 at its left end, connecting the upper triangular lever 7 and the operating lever. The rod 22 may be bent by the joint 22a between its ends. The upper triangular door lever 7 is secured at the pivotal point 7b. The upper triangular lever has pivot points 7x, 7z and anchorage point 7y that move with the triangular lever around the pivot point 7b, of which the upper pivot point 7z engages at its right end with a bar 22. When the bar 22 is pushed to the right Clockwise rotation is facilitated by a tension spring 23 which pulls downward from the anchorage point 7y on the right toward the tension spring anchorage 23a in the suspension plate. The tension spring 23 would not necessarily be needed if the rod 22 had no joint 22a. Clockwise rotation of the first triangular lever 7 raises the left pivot point 7x of the triangular lever 7, thereby pulling the right pivoting point 8y upwardly of the second triangular lever 8 by the second bar 24 to cause the triangular lever 8 to rotate anticlockwise around the pivot 8b. The first end of the second rod 25 is fixed at the pivot point 7x and the other end at the pivot point 8y. The pivot points 8b, 8x, 8y of the triangular lever 8 are located near the corners of the triangular triangular lever 8.

The foregoing description of movements of the various parts of the linkage 30 applies in fact both inside and outside the level range and is ♦ · resulting from a rotation of the operating lever 5 by sector 6a when the door instruction, i.e., drive actuation, changes from closing to close.

1 and 2, a situation in which the elevator car is out of the level area, and then, in figures 3 and 4, a situation in which the elevator car is in the level area will be described.

At the pivot point 8x of the triangular door 8, a third rod 25 is fastened at its first 5 ends by a third rod 25 pivotally supported at its right end by a pivot point 25a between its ends. The locking lever 11 remains substantially stationary. Retaining is secured by a pusher spring 12 which presses upward on the left end 10 of the locking lever, which further pushes the locking hook 10 into the door locking position. In the drawings, springs 12 and 23 are shown only in Figure 1. As the triangular lever 8 moves the first end of the rod 25 with the pivot point 8x to the right, the rod 25 pivots about the pivot point 25a and the fourth rod 26 moves the first pivoting lever 27 between the pivot point 27a to the left. The fourth rod 26 is pivoted from its first end 25x to one end of the third rod 25 and from its second end to the pivot point 27a of the first suspension lever 27. The damper 15 is mounted to the entrant by two suspension levers 27 and 28. The first suspension lever 27 and the second suspension lever 28 are pivotally mounted on the suspension plate 1 at its first ends, which are pivotally movable with respect to the integrator. 25 points out of 27x, 28x. At one end, the suspension levers 27 and 28 are secured by the pivot points 27y, 28y at the other ends of the damper 15. The suspension levers 27 and 28 are of the same length. The pivot points 27y, 28y, 27x and 28x are arranged with respect to the hanging plate 1 such that, when the hanging levers 30 are rotated 27,28, the damper 15 remains vertical. Thus, the movement on the linkage does not unlock when outside the level zone, but moves the damper 15 to the left. The pushing spring 12 ensures that the damper moves to the left. Due to the force exerted by the push spring locking lever 11, the pivot point 25a is held in position as the pivot point 25x moves.

In the following, with reference to Figures 3 and 4, a situation is described where the elevator car is in the level area and the car door is unlocked.

Figure 3 shows a sector 6a 5 illustrated at the pivot point 6 to illustrate the angle at which the operating lever 5 first rotates clockwise relative to the pivot point 6, and the sector 6A whose operating lever 5 then pivots to engage the engaging member 4 on the plane door rolls 17,18.

The operation of the linkage, as described above, results in e.g. 10, the rotations of the triangular levers 7 and 8, illustrated by sectors 7a and 8a drawn on them. Since the elevator car is in the level area, the right-hand damper 15 responds to the right-hand roller 18, some of the movement of the linkage parts takes place unlike when out of the level area. As already mentioned 15 above. The roll 18 is a so-called roller. a fixed roll, i.e., roll that which remains substantially stationary with respect to the plane door as the engaging damper responds. The roller 17, on the other hand, can move somewhat with respect to the plane door, whereby the movement caused by the compression-20 applied to it by the catch damper 14 can be used to open the plane door lock. As the damper 15 responds to the roller 18, the damper 15 is prevented from moving to the left. It is important for the desired function that the third rod 25 is rotated clockwise about the pivot point 25x by the angle illustrated by sector 25A as a result of the counterclockwise rotation of the triangular lever 8. Fig. 4 shows the positions of the parts of the linkage 2, the dampers 14 and 15 and the lock 10, which they are positioned through the linkage as a result of movement of the operating lever sector 6a. A pivot point 8x of a triangular door 8 has a third rod 30 attached at its first end, supported by a lower end to a fourth rod, and a pivot point 25x at its end serving as a pivot of its pivot when rotated by the triangular door lever from its upper end. Since the movement of the right-hand damper 15 and thus also of the suspension lever 27 is prevented, the pivot point 25x at the right end of the fourth bar 35 acts as a substantially stationary support for the pivoting of the third bar 25. The action of the thrust spring 12 on the lever 11 then disappears on the support force indirectly obtained by the pivot point 25x9 102673. Thus, the pivot point between the ends of the third rod, where the L-shaped locking lever 11 is closed, is pulled a good distance to the right. The movement of the locking lever 11 pulls the lock 10 open, whereby the opening of the car door 5 may begin. At the same time, a safety switch 13 in connection with the lock 10 is opened, which provides electronic information to the elevator safety circuit and, if necessary, to the elevator control whether the car door is locked or not. After unlocking, the operating lever is further rotated by the amount of sector 6A shown in Fig. 3, by which the operating lever rotates to move the right-side engaging damper 14 to the right-hand leveling door roller 17 and finally squeezing the leveling door rollers 17,18 between perfect. The actuation lever 15 can be swiveled unhindered by sector 6A, since the rod 22 is provided with a hinge 22a from which the rod can be folded, so that the bending of the rod 22 substantially absorbs the action of the release of the lock in the direction of the triangular lever 7.

It will be apparent to one skilled in the art that the various embodiments of the invention are not limited to the examples set forth above, but may vary within the scope of the following claims.
