task

The invention has for its object an anti-panic door lock with the Dimensions according to DIN 18251 and 18250 part 1, e.g. B. an anti-panic hotel lock, the presupposed genre to improve that the lock judge is largely spared in handling in the conventional sense and there is nevertheless a relatively simple, functional construction.

solution

The object is achieved by the features reproduced in claim 1 solved.  

Some advantages

When the magnet is not energized, the outside of the nut wing runs through empty supports itself with a concave shoulder on a Ge during idle stroke wind bush. If the lock is blocked, a person can open it from the outside press the door handle without inadvertently exerting any force on the Act on lock mechanisms and damage them. This also results a less large load on the nut and the handle square and one corresponding extension of the lifespan of lock and fitting. The opti The impression of a handle hanging from the load is given by the Invention also improved since this disadvantage no longer occurs.

Due to the construction, permanent energization of the Solenoids no longer required. The current is rather in the milli seconds range, during two impulses, namely for the impulse "movable clutch lever engage" and impulse "more flexible Clutch lever back ". This means that little energy is required and increase the service life of a battery that may be installed in a fitting enlarged.  

The nut is equipped with a washer in the center to prevent the to avoid shared pushers. The inner nut wing is used for direct actuation of the latch and at the same time to actuate the entire anti-Pa nik function.

The invention can also be particularly advantageous in that from the anti-wear pattern G 91 04 766.8 from the applicant Use panic lock. Here the lock can be used especially indoors be applied when e.g. B. a door equipped on both sides with a handle unauthorized outside should not be used while inside can leave the room at any time.

Furthermore, such locks can be equipped with sensors or limit switches who monitor the respective bolt and latch position and are therefore part of a status or access control system.  

This also opens up the possibility of an inventive one Locked in connection with an electromagnetic blocking in flight use safety devices. Only by triggering an alarm, e.g. B. emergency button, Smoke fire alarm systems, alarm systems or the like will Blocking removed and the escape route released.

DIN 18 251 provides a hole 46 mm above the center of the nut, which in the Rule for fitting hardware was provided, but usually not is used. There are also drilling templates for this. The invention enables an easy installation of the power supply in that a miniature plug connection within the lock through this hole to the electricity supplier supply can be coupled so that no special cutouts or Holes are required to produce the power supply. At which he inventive lock can therefore the bore 46 mm above the Nut center can be selected. This hole is covered by the fitting. The Power supply from the battery can therefore be described above Whoever installs the plug-in connection without additional effort the.  

The solenoid can be insulated on a brass or art be attached to the fabric part.

The plug part can be divided into a plastic socket and a two- or three-pin miniature plug. The miniature socket is made using a six Nut or the like fastened in the plastic sleeve. The wiring between solenoid and miniature socket and the associated soldering takes place externally and is inserted as an assembly during lock assembly builds. The miniature plug is also external and is only used by the Installation of the fitting connected (inserted).

Furthermore, a lock according to the invention can be used advantageously with one Lock in accordance with the German Ge dating back to the applicant Use pattern G 92 07 865.6, because when the end of the Clutch lever of the driver cams now non-positively behind the inner one Nut wing lies and the retracting movement of the latch and bolt latch as in that German utility model G 92 07 865.6.

As already described, is in the rest position (the outer handle runs empty) the solenoid or a hinged armature magnet, a relay or  the like in the de-energized state. The non-neutralized permanentma gnet now holds him in this position. About the anti-panic function and one The lock can always be opened from the inside. In the event of an accident, e.g. B. Power failure of the battery can also with a lock cylinder bolt locked the emergency opening by the master and emergency key be made. In principle, a half cylinder is sufficient for this.

The reference numeral 1 designates a lock plate, and 2 a lock cover, while 3 represents a cuff which has openings for a latch 4 , a latch bolt and an auxiliary latch.

With the reference numeral 5 is an inner nut wing and with the reference numeral 6 an outer nut wing of the door to be locked (not shown) is designated net ( Fig. 11 and 12).

A nutshell has the reference numeral 7 with which the two nut wings 5 and 6 are very precisely positively coupled by a simple plug connection. The nutshell 7 also has a square aperture in the center for receiving a press mandrel, not shown. Between the two nut wings 5 and 6 and in a central recess in the nut shell 7 , a disc 8 (FIGS . 13 and 14) is arranged, which prevents the pushing pin from being pushed through the nut shell 7 .

9 with a web is referred to, which is acted upon by a counter spring 25 and is supported on the nut wings 5 and 6 , namely in a groove of the same, so as to prevent slipping and thereby presses the nut and thus a presser pin into the position shown in FIG. 1. The reference numeral 10 denotes a movable clutch lever, which is in the rest position by the force of a tension spring 23 and a lifting magnet 14 . Here, the outer nut wing 6 is not in engagement and turns when actuating the outer handle against the force of the counter spring 25 empty by up to the stop against a threaded bushing 18 in the lock case, preferably before between the lock plate 1 and the lock cover 2 , is immovable.

About a magnetic or chip card in the manner of a credit card is triggered by a card reader and the corresponding electronics, a pulse lasting about twenty milliseconds when the card in question is inserted into a slot, not shown, of a fitting part, a pulse . Thereby, a permanent magnet is neutralized in the solenoid 14, whereby a pin member 29 via a building-side spring 30 a stroke of z. B. executes about 2.5 mm. The pin part 29 meets a lever 11 of the movable clutch lever 10 , the design of which is particularly clear from FIGS. 15 and 16.

Against the force of the tension spring 23 , but supported by the favorable center of gravity or its top heaviness, the movable clutch lever 10 falls into its actuating position in which it engages behind a nut arm 31 of the nut wing 6 . The end 34 of the movable clutch lever 10 is now offset by a few tenths of a millimeter in front of the nut arm 31 of the outer nut wing 6 . At the same time there is a drive cam 32, which protrudes orthogonally to the underside of the movable clutch lever 10 to this and is integrally connected to the movable clutch lever 10 and with a few tenths of a millimeter play behind the end face 33 of the inner Nußflügels 5 is incident. When the trigger pin is pressed down, the latch is taken and pulled back into the lock case.

By pressing the outer handle engages the obliquely arranged, claw-like nut arm 31 of the outer nut wing 6 behind the claw-shaped, inclined end 34 , so that the end 34 is prevented from sliding away from the nut arm 31 .

With 12 screws, with 13 a cylindrical pin and with 15 and 17 also screws.

19 is a latch spring, 20 a spring guide, 21 shoulder mandrels, 22 grooved mandrels and 24 a square mandrel, while 26 represent screw sleeves.

At 11 , a trigger designed for a solenoid is shown, while 16 relates to a mounting bracket for the solenoid 14 .

To install the fitting, the stop requires a drilling template. In As a rule, these are the holes on the right and left for rosette fittings next to the nut and the cylinder.

For short, wide and long signs, these are the holes 21.5 mm below the middle of the nut and under or above the lock case. The DIN 18 251 provides a bore of 46 mm above the center of the nut, which is usually used for Fitting attachment is not used.

Due to the existing construction and the space-saving structure of a Miniature connector to power the magnet inside the It is possible to find a location convenient for the castle To create a connector. For this position was in the present case selected the hole 46 mm above the center of the nut. This hole will covered by the fitting. So it makes sense to power one battery not shown in the fitting integrated over the described Install the plug connection underneath the fitting without additional effort.  

Towards the castle ceiling, the cylinder pin 13 penetrates the movable coupling lever into an elongated hole and stands approx. 0.3 mm above it in order to be supported towards the castle ceiling 2 . As a result, the movable clutch lever 10 always runs freely and cannot: jam between the latch 4 and the ceiling 2 .

The magnet 14 is designed as a bistable solenoid and can be attached in a special version and preferably for insulation reasons to a brass or plastic part.

The plug part 27 (see FIG. 22) is divided into a plastic socket and a two- or three-pole miniature plug connection. The miniature socket is fastened in the plastic socket with a hexagon nut. The wiring between the solenoid 14 and the miniature socket and the associated soldering is carried out externally and is installed as an assembly during lock assembly. The miniature plug is also located externally and is only connected (inserted) when the fitting is installed.

The trap 4 is designed in one piece as a beam trap. The clutch lever is used to hold the cylinder pin 13 , the z. B. can be 4 mm thick and which extends through an elongated hole 37 of the movable clutch lever and protrudes somewhat. The cylinder pin 13 is guided in the lock plate and at the same time needed as a latch stop to the faceplate.

The two nutshells 7 are preferably made of sintered metal C 39 or similar chemically, but precisely manufactured other materials. In order to be able to absorb the load moments through the handle actuation, the plug connections of the nut wings 5 and 6 with the nut shells must be designed precisely.

The mode of operation of the embodiments shown in FIGS. 1 to 18 is as follows:
The movable clutch lever 10 is in the rest position by the force of the tension spring 23 and the lifting magnet. The outer nut wing 6 is not in engagement and, when the outer handle is actuated, rotates empty against the force of the counter spring 25 until it stops against the threaded bushing 18 . This means that sensitive parts of the lock are not stressed. If a magnetic card or chip card is read in via a card reader, the electronics generate an approximately 20 millisecond pulse. As a result, a permanent magnet is neutralized in the lifting magnet 14, as a result of which the pin part 29 executes a stroke via the spring 30 . This pin part 29 hits the lever 11 of the movable clutch lever 10 . Against the force of the spring 23 and supported by the top heaviness, the movable clutch lever 10 falls into an actuation position. The end 34 of the clutch lever 10 is located in front of the outer Nußflügel 6, at the same time the driver is located 32 of the movable clutch lever 10 behind the inner Nußflügel. 5 By actuating the outer pusher, the end 34 of the clutch lever 10 is carried along via the claw-like nut arm 31 , whereby the driver 32 of the inner nut wing 5 is also taken along. When the end 34 is actuated, the driver cam 32 now lies non-positively behind the inner nut wing 5 . The retraction movement of latch 4 and latch bolt can be carried out as described in German utility model G 92 07 865.6.

An elongated hole 37 in the movable coupling lever 10 is required for the advance of the inner nut wing 5 in order to pivot the latch lock out of the range of motion of the latch 4 . The door can now be opened, the handle is in its initial position, the movable clutch lever 10 is still in the swivel range of the outer nut wing 6 .

In the event of a further current pulse, which acts variably over time through the electronics, the solenoid 14 picks up, at the same time the movable clutch lever 10 , supported by the tension spring 23 , swings back into its initial position.

With the door closed and the bolt locked, the lock can be opened by always open inside using the anti-panic function. However, from the outside it turns Then press the button empty.

In its rest position, the magnet 14 is de-energized and the outer handle runs through empty.

The embodiment of FIG. 19 differs from the embodiment described above in that a tension spring 38 holds the movable clutch lever 10 in its basic position I.

After energizing the folding magnet, the switching lever 39 pivots from position A to position B. About the cam of the movable clutch lever 10 this is moved from its basic position into its functional position II. The trap 4 can thus be withdrawn depending on the time (via the anti-panic function). The tension spring 38 pulls the movable clutch lever 10 back into its basic position 1 via a further pulse. The Schalthe bel of the hinged armature magnet 14 lies below the grooved mandrel, so that the water can slide over the switching lever 39 when the case 4 moves.

In the embodiment for FIG. 20, as in the embodiment according to FIG. 19, the same reference numerals have been used for parts with the same function.

A permanent magnet 40 is located on the movable clutch lever 10 . This is also a permanent magnet 40 attached to a soft iron core 41 so that the poles repel each other. The electromagnet with the soft iron core 41 is connected to the lock plate, so it does not move with it. In the basic position, the movable clutch lever 10 is due to the magnetic field, always in position I. By energizing the coil of the electromagnet, the magnetic field is reversed and the movable clutch lever 10 falls into its position II. No contact should occur between the magnets . The lock can be opened in the specified time. Electricity is equal to the door opening time. With the vorei loins by spring force trap 4 of the movable clutch lever is pulled in the area of the now again repulsive magnetic field 10, the basic position is achieved by there again.
