Description

[0001] The invention relates to a door lock for a box door of an elevator, with a housing and a latch that in relation to said door can be put in a closed position and in a release position and that is housed in the housing, a mechanism of coupling that cooperates with the latch and that can operated by an external device in the form of a elevator car thus carrying the latch from its position

closing

to its release position, provided a

device

from blocking for to block he latch in its

closing position

[0002] It has been proven that there are repeatedly unauthorized persons who, with inappropriate actions, they try to open an elevator door to access the box of the elevator This puts these people in danger considerable. Sometimes such people try to manipulate the coupling mechanism actuated by the device external, for example an elevator car, to open a box door There is therefore a need to limit the accessibility to the hollow box of the elevator at a service of elevator according to regulations. To this end they would be imaginable measures such as hindering the accessibility of coupling device, but this would require a intervention in the overall operation of the system elevator. There is also the possibility of installing locks of additional door in the door of box, with what access to the elevator box would also be difficult. Without However, this requires a great expense and is not adequate for a later equipment of the elevators.

[0003] In part there are also legal provisions according to which should be generally impossible to open a door of elevator if there is no elevator car behind it. On the other hand, authorized persons must have everything moment the possibility of opening the cash doors by an emergency unlock key regardless of the position of the cabin to, for example, be able to free people locked up, so that all the doors of lift must be unlocked by operating a switch corresponding in a protected place, for example the room elevator control Therefore, the door lock must be specially adapted to comply with these provisions legal or at least be modified in the simplest way possible to meet these requirements. [0004] EP 1460018 A1 describes a lock Door lift with a latch, which closes the door and that can be operated by a cranked lever, and with a locking device, which acts on the pivot center of the angled lever producing a lock. [0005] Document DE 19743655 A1 describes a device lock for a lock, in which, to unlock the latch, an unlocking device is provided which is totally independent of the latch mechanism of the lock and in which the unlocking is done if an issuer emits a coded unlock signal. [0006] US 2307542 describes a lock for elevator doors with a latch, in which it is planned [0007] a locking element that acts on the latch. [0008] Thus, the invention aims to create a door lock that is specially adapted or can be adapted to an elevator system that hinders the access to the elevator box to unauthorized persons and by

means of which the legal provisions are complied with above mentioned or they can be fulfilled by Simple modification measures of the elevator system. [0009] The objective is achieved by a lock of door according to claim 1. [0010] In the door lock according to the invention is provided a blocking device that acts directly or indirectly on the latch to lock it in its closing position During normal operation, the Locking device can be operated preferably in function of the actual positioning of the external device, such as the elevator car corresponding to the door lock, and with special preference just for is. Additionally, the locking device must be liable to operate from a protected place, as per for example, the corresponding elevator control room, for example for maintenance work or in case of emergency. Therefore, it is not possible to bypass the blocking device by operating, in an unauthorized manner, the coupling mechanism actuated by the device external. The blocking element preferably acts in drag on the component to block, and in case also given in force drag. Locking device can be operated by electrical means, preferably only for these, so that manipulation is prevented mechanical for unauthorized release of the lock door, like the one that is frequently attempted by screwdrivers, wires, cables or the like. Be understands that the door lock according to the invention It can also be used in other equipment or devices transport. According to the invention, the blocking device acts directly with a blocking element on the

latch and / or can act on the coupling mechanism which is arranged in the door lock housing and which in turn cooperates with an external device, as per for example an elevator car or other means of transport, to be able to bring the latch from the closed position to The position of release. For this purpose it may be installed in the external device a drive mechanism or element of actuation acting on the mechanism of coupling The drag mechanism may be installed directly in the cabin or, for example, in a device stationary or modifiable position thereof, such as an extendable latch cam. In the mechanism of coupling can be installed an element of coupling, such as a contact pulley. The same time, the blocking element can also act on a drawbar usually provided as part of coupling mechanism, which can be coupled to a angled lever that preferably acts directly on the latch. [0011] According to the invention, the blocking element can, to lock the latch, act on a toothed lever provided in the coupling mechanism, which, in most of the cases, it is executed as an angled lever. He turning movement of the toothed lever can be locked in particularly favorable conditions of force, for example if a blocking element acts at least essentially tangential way about a drag mechanism that protrudes radially from the axis of rotation of the lever angled as a coupling element. The forces that of this mode acts on the blocking element when it occurs the lock against an intentional actuation of the latch they can be absorbed by the counter-support of the element of

blocking in a particularly favorable way. The element of blocking can be performed in general as a lever angled, but also as a simple lever, being able to lever support point be arranged opposite to component to be locked, in particular to the toothed lever. The lever, or angled lever, changes position here by means of a drive element to be able to take it to Your locked position. The drive element can act on the arm of the angled lever that is between the support of the angled lever and the component a lock, for example the toothed lever or the latch. In In this case, the drive element of the device lock can also act on the lever arm

layered

opposite to the component to to block with relationship to the

support of the angled lever.

[0012]

He device from blocking may actuate

preferably by means of a drive device electric, which with special preference acts directly on the blocking element. [0013] The provision of the angled lever as an element of lock allows to adapt the locking device with little spending at different conditions, for example different drive elements. So, for example, the device lock can be operated by an electromagnet, which with preference acts directly on the blocking element or the drive element thereof. The drive of blocking device using an electromagnet has as advantage that the locking device can be activated by means of a command, said command being able to be adapted to the more diverse requirements and also be arranged in one place protected, such as the system control room of elevator. In the locked position of the element

blockage, the electromagnet can be under current or preferably without power, so that the device lock is in its locked position even if, by For example, there is a breakdown of the remote control or a power outage. stream. [0014] According to an alternative, the locking device is preferably arranged in the lock housing door, so that it is protected against interventions external [0015] According to the invention, the blocking device can be also arranged externally to the housing of the door lock, for example due to the necessary space. For this purpose it can be provided in the housing of the door lock a housing opening through the which can pass the blocking element to act on the element to be locked from the door lock, for example a latch, a toothed lever or a part of the mechanism of coupling, such as the drawbar. How alternative a coupling can also be provided that go through the door lock housing and over which The locking element can act. In this case, the locking device, possibly with a housing corresponding, it must be arranged in a suitable place in the exterior of the door lock. To do this, the device lock can be fixed to the housing of the door lock or also to another component, as per example to the fence of the door corresponding to the lock door, to an adjacent wall, etc., so that at least when the door is closed, the locking device can act on the element to be locked from the lock of door.

[0016] A particular configuration is achieved advantageous when the toothed lever is installed, coaxially with respect to its axis of rotation, an extension leading to the outside of the door lock, acting the locking element outside the lock housing of door over the extension itself or over an element of coupling acting on it. So, for example, the extension can be configured as a bar extension, which can also be manufactured in a tube profiling that can also be used to make a key an emergency release device assigned to the door lock, that is in most cases a triangular profile The extension and the key of a emergency release device can therefore act if necessary on the same coupling element of the door lock and extension can be adapted in its length to the requirements in question. So the coupling of the locking device or extension it is preferably detachably attached to the door lock. In the prolongation it can also be arranged a coupling element, such as a disk of blocking or similar, on which the blocking element of the blocking device can act producing a blockage to prevent the latch from moving to its position of release. The coupling element arranged in the prolongation may protrude from the radial extension and / or axially The coupling element may present by example a housing for the blocking element, with the in order to be immobilized by it. The coupling and the locking disc are fixed in each case preferably No possibility of rotation. The extension can here be coupled to, or placed on top of, a stump of the axis of rotation of the

toothed lever, to which a spanner can also be attached a standard emergency release device. [0017] The locking device is activated with special preference via a command that is configured so that, during normal operation of the elevator, the locking device is placed in the position of unlock only if behind the box door corresponding to the door lock is arranged in a correct position an elevator car correspondingly, or similarly of another device of transport. Instead, if behind the box door corresponding to the door lock is not arranged an elevator car in rest position or in its position correct, during normal elevator operation the locking device is always in its position of blocking. A sensor is preferably provided for this purpose. which emits a signal when behind the box door corresponding to the door lock is arranged a elevator car in a correct position and the latch It can be unlocked as prescribed. Thus, during normal operation of the elevator, the device lock is brought to its unlocked position only when the sensor indicating a positioning correct of the elevator car in the box door emits a signal. The emission of the signal by the sensor can be a necessary or sufficient condition for unlocking and therefore also depend on other parameters of elevator operation. The command can be the same

command of

elevator or constitute a separate command The command

is

willing prefe recently in a protected place, by

example

the room from I send of the elevator. In case dice, he

sensor can also emit the signal directly to the

locking device The locking device features further preferably a drive device

electric,

how by example a electromagnet or a engine

electric,

what drives he elemen to from blocking direct or

indirectly.

[0018] Once the locking position of the blocking device by persons authorized to do so, an emergency manual release can be performed on the door lock. Eventually, the locking device can also be placed in its unlocked position by operating the emergency release device of The door lock. As a release device of emergency may be provided for example an element of coupling arranged on the axis of rotation of the lever toothed, for example an axially protruding stump, which can be operated by means of a key of a device emergency release, such as a triangular key usually planned for this purpose. [0019] Alternatively, or additionally, there is the possibility that the locking device is coupled to a command of an emergency release device and can be operated by it through a control element emergency and placed in its unlocked position regardless of the sensor signal. Through this emergency command can be placed in its position of unlock the locks locking devices of insulated door of the elevator system, or all of them, of so that access to the elevator box is allowed. The command emergency may be arranged in a protected place and Be part of the elevator control. It is preferable that the one emergency release device possible exclusively through a command, in particular a command

electrical, that is, not by mechanical intervention direct on the door lock for example by means of a key of an emergency release device. [0020] The sensor that detects the correct positioning of the elevator car can have multiple ways of embodiment, for example that of an optical sensor, a barrier of light, a magnetic sensor that reacts sensitively to an element placed in the elevator car, a sensor Optoelectronic, a mechanical sensor or other suitable sensor. The sensitive element for the sensor may be arranged directly in an area of the elevator car and in case also given in an additional cabin device elevator, which can also be of modifiable position, such as for example a cab latch cam, such as the usually provided for the actuation of a mechanism drag, such as a contact pulley, with the in order to act on the coupling mechanism of the Door lock that is attached to the latch. In this case, the latch cam extends only if the cab elevator is destined to stop behind a door selected, but not in cabins that only pass by the door. The modifiable position device can activate by means of the command to modify its position. How alternative to the latch cam may also be provided another device that changes its position or its status if the elevator car is destined to stop at a default cash gate corresponding to the door lock. [0021] The signal received by the sensor indicating that a cabin has reached its correct position, to unlock the blocking device, and / or the signal emitted by the sensor at command and / or directly to the locking device may be

properly coded to hinder handling errors and in particular also external interventions. The coding can be done by modulating the signal. The coding can also be done depending on the respective cabins used, so that the sensor, or the command, can detect if a specific cabin of several cabins are arranged behind the door corresponding to The door lock. [0022] The command can be performed in such a way that the Unlocking the locking device is performed only if a concrete cabin, or several cabins selected from a countless cabins, is / n arranged in position correct in a box door corresponding to the lock Door in question. [0023] If applicable, the sensor can also detect other parameters of the elevator cars, as an alternative

or additionally to the position, to emit a signal to the command and / or to the locking device in order to carry this last to an unlocked position. The sensor can detect for example also the speed of the elevator, so that no an unlock is made if the elevator car moves still at a certain speed when it is arranged behind the Door corresponding to the door lock in question. [0024] The correct position of the cabin, which through the command leads to an unlock of the locking device, can also be detected if necessary by means of a control device The control device can, by example from movements or changes of state of the cabin drive device, determine the actual position of the latter and if necessary also others parameters, such as cabin speed, and can

be made for example as a decoder of travel. [0025] The invention is described below by way of example and is explained by way of example by Figures, which show:

-

figure 7, a door lock according to figure 6, with the locking device in the unlocked position. [0026] Figure 1 shows a schematic representation of a door lock 1, in particular for a door of an elevator box, with a housing 2 and a latch 3, that is housed in the latter and that can be put into a closed position (figure 1) and in a release position (figure 2) regarding a door. It is also planned a coupling mechanism that cooperates with latch 3 and that You can present a serrated 4 with a serrated 5, which

it is made in the form of a bent lever and housed in a way rotating on the axis of rotation 6 and that, by means of a bar traction 7 acting indirectly or preferably directly on it, it can be placed in at least two positions of turn corresponding to a release position and a latch closing position 3. The mechanism of coupling, if necessary the pull bar 7 directly, can be operated by a device external, for example an elevator car 19, when the external device enters its nominal position or at least It is almost there. To do this, the mechanism of coupling can present a drag mechanism configured for example as a contact pulley, which can act in conjunction with cabin 19 or a part of the same, for example a position latch cam modifiable, to cause a change of position of the toothed lever 4 and / or latch 3. [0027] To safely prevent an opening, do not authorized closed box door, and with it a unauthorized entry in the elevator box or in general the operating space of a device or device transport, a locking device 10 is provided that it has a locking lever 12 that can be operated by means of an electromagnet 11, by which it can lock the latch in its closed position. According to him exemplary embodiment, the axis of rotation 6 of the lever toothed 4 is widened radially as an element circular 14 and it is arranged without turning an element 13 projecting radially in the form of a projection and on which the locking lever 12 acts to lock the rotation of the toothed lever 4. The blocking arm 15 of the lock lever 12 is essentially arranged so

tangential to the outer perimeter of the axis of rotation 6 or the circular element 14, so that when the blocking arm 15 is next to or adjacent to the toothed lever 4 blocks a turn of the toothed lever 4 in cooperation with the element 13. Since the toothed lever 4 cooperates directly or also indirectly with latch 3, the latter also It is locked in its closed position. [0028] Lock lever 12 is configured here as a bent lever, such that the blocking arm 15 is disposed between the axis of rotation 16 and the actuator of the lock lever, electromagnet 11. According to the example, in the lock position of the lock lever 12 the electromagnet 11 is out of current, and when electromagnet 11 the lock lever is in current position unlocking (figure 2), so that, by activating the coupling mechanism, such as the bar traction 7, it is possible to turn the toothed lever 4 and carry with it the latch 2 to its release position. [0029] The electromagnet 11, or if necessary also another actuator, is activated here by means of a knob 17, which is coupled to a sensor 18 under signal transmission. He sensor 18 is configured to indicate the layout correct of an elevator car 19 in its nominal position behind the box door corresponding to the lock of door 1, being able to be arranged in cabin 19 a element 20 to which sensor 18 is sensitive. Sensor 18 it can be in particular an optical, magnetic sensor, electro-optical or mechanical Element 20 may also be arranged in particular on an extendable latch cam 21, which extends to an active position when the cabin approach the box door respectively selected by a person, to interact with a

drive element, such as a contact pulley, and actuate the coupling mechanism attached to latch 3. In if necessary, the element may also be arranged in another suitable modifiable position device of the cabin. [0030] The sensor is also configured so that in the passive position of the latch cam or the device Modifiable position of the booth 19 no signal is generated any. The passive position of the latch cam is given by example when the cabin only passes by a door of box. [0031] The aforementioned signal generated by sensor 18 it is transmitted to command 17 or, if necessary, also directly to the locking device. Knob 17 drives then the actuator, for example the electromagnet 11, of the lock device to unlock directly or indirectly latch 3, so that it goes on to occupy Your position of liberation. According to the embodiment example, for this, the locking lever is placed in its position of unlocking shown in figure 2 using the electromagnet excited by current. [0032] Element 20 and sensor 18 are preferably willing and mutually adapted so that the Unlocking the locking device is done in time before or practically at the same time as the drive of the coupling mechanism to rotate the toothed lever 4, or in general to bring the latch to its position of release, which is generally applicable according to the invention. The temporary adaptation is preferably such that

he

latch be I carried to its position from release

immediately

after from to have occupied he device from

Lock your unlocked position.

[0033] The control 17 also has a control element 22 so that it is possible to unlock the locking device 10 regardless of an output signal from sensor 18. This it is necessary for, for example in case of emergency, allow access to the box through the box door corresponding to the door lock. If necessary they can operated with control element 22 one, several or all

the

dispositives from blocking from the locks from door

willing

in a box, the that may be done

simultaneously

or in relationship with, in every case, a

Door lock selected. Command 17 is at General arranged in a control room protected against entry of unauthorized persons. [0034] The embodiment according to figure 3 is difference from that of figure 1 by the configuration of the locking device, presenting the locks so others the same design. The same elements carry equal references. As in the case of Figure 1, the Lock lever is configured as a bent lever, but, unlike the case in figure 1, the actuator or electromagnet 11 acts on the arm 25 of the lever lock that is not the locking lever 15. In the state without electromagnet current 11, the lock lever 12 is is in its unlocked position (figure 3). So, the arrangement of the electromagnet 11 can be adapted to the respective spatial conditions. It is understood that, according to both examples of embodiment, in the state of the device lock respectively represented the electric motor it can also be inversely under current or without current, for example by arranging the compression spring 26 respectively on the side of the electromagnet opposite the lock lever 12 and causing it to act on shaft 27.

[0035] In the exemplary embodiment according to Figure 4, the locking device 30 is arranged externally to the door lock housing 2 1. In addition, regardless of this, the locking device 30 acts directly on latch 3. In figure 4, the locking device is represented in its position of blocking. The blocking element 31 goes through a opening 32 of the housing 2. The locking element can intervene here in a latch recess or grab by behind the terminal area of the latch and intervene for it for example in the housing bore 33 in which it is the latch housed. The locking device 30 may be fixed to a support 34, which can be fixed to the housing 2 from door lock 1 or to another device, as per example a door fence, the device being able to lock 30 be provided if necessary in a housing additional 37. The electromagnet 35 of the locking device it can also be configured here, as in all others configurations of the invention, such that the locking device 30 is in its locked position with the electromagnet 35 under current or without current, for which compression spring 36 may be arranged in the side of the electromagnet 35 which oriented towards the element of lock 31 or in the opposite direction to it (also agree with figure 5). [0036] Figures 6 and 7 show another form of realization of the door lock according to the invention, with a locking device 40 arranged externally to the door housing 2. Unlike figure 1 (so other, the same elements have equal references), in the toothed lever 4 acting on the latch is intended to attach the locking device to the latch

a coupling, which here is configured as a Coaxial extension of the axis of rotation 6 of the toothed lever. The coupling 41 can be coupled here to an element installed on its axis of rotation 6, which can also be attached a key of an emergency release device for unlocking the door lock in case of emergency, by example a triangular stump. So, the link can consist of a corresponding triangular hollow profile, such as the one generally used to manufacture a key An emergency release device. To facilitate the blocking action of the blocking device or element lock 42 in the coupling 41, a coupling element 44 configured as a disk of lock, which has a recess 45 in which you can intervene blocking element 42. It is understood that the coupling element 44, provided that it is provided, and the coupling 41 act in each case without turning one on the other or on the axis of rotation 6. To operate the locking element 40 is again provided with an electromagnet 11, which is out of current or under current when the locking device is in its locked position. [0037] It is understood that the arrangement and configuration of other devices, such as control 17, sensor 18, element 20, etc., can be applied in general as has been described in figure 1 also for the other examples of realization or also for other configurations of the door lock according to the invention.
