Description

The invention relates to an anti-panic hotel lock which can be actuated by a key and / or by a handle and has the dimensions according to DIN 18251 and 18250 part 1, with a split nut, change, tumbler, latch and latchbolt, which are arranged in a lock housing, with an intermediate Latch bolt and latch arranged additional latch, which, like the latch and the latch bolt, each emerges from an opening in the cuff against the restoring force of a spring element, the additional latch being guided in a longitudinal slot on the lock housing base and an automatic locking mechanism also arranged in the lock housing, which locks the latch and controls the latchbolt.

An anti-panic hotel lock according to the preamble is known from DE-GM 92 07 865.6, which goes back to the applicant.

A similar lock also relates to DE-GM 91 04 766.8, which also goes back to the applicant.

From DE-PS 36 43 388 an electrically controlled lock with a spring-loaded lock nut is known, which drives the latch via an eccentric lever, the lock nut additionally having a cutting lever, which in the idle state has an armature against the yoke of a spring-loaded control lever Electromagnet presses and the cutting edge runs against a locking pin of the control lever when the magnet is not energized, whereas it runs past the locking pin when the armature is held. The control lever can be a two-armed lever, the lower lever arm of the armature and the upper lever arm having a retaining pin and a locking pin. The underside of the cutting edge can rest on the holding pin in the rest position, while its upper side runs against the sharp-edged locking pin when the door handle is actuated and when the magnet is de-energized. The locking pin can be diamond-shaped and its acute-angled edge can face the cutting lever. A lever, known as a change, is provided between the bolt and the latch, which enables the free-running latch to be actuated via the bolt drive. A handle attached to the inside of the door can act as a bolt drive to serve. The release pulse can be derived from a coding unit. The release pulse is derived from the code card reader. The release pulse can also originate from a pushbutton arranged in a control room. It is also possible to insert a light-emitting diode indicating the release into the lock housing.

EP-PS 0 339 117 relates to an electrically controlled lock with a spring nut under lock and free-running case, the lock nut additionally has a control element and a locking lever is provided which faces a locking lug of the lock nut. The control element is deflected via a control lever, which takes along a locking lever provided with a magnetic armature via a weak leg spring. The control lever and the locking lever can be pivoted as two-armed levers on a common stud.

The known types described last have the disadvantage that the pushers are blocked. Due to the well-known structure of a split nut, the load moment on the handle only affects the part of the nut. This is disadvantageous in that both the nut and the square handle are exposed to a greater load and are therefore more susceptible to failure. The operator has namely, the need to act adversely on the blocked pusher, which does not yield in this construction.

The invention is based, an anti-panic door lock with the dimensions according to DIN 18251 and 18250 part 1, z. B. an anti-panic hotel lock, to improve the presupposed genre in such a way that the lock set-up is largely spared during handling in the conventional sense and yet results in a relatively simple, functional construction.

The object is achieved by the features set out in claim 1 .

When the magnet is de-energized, the outer side of the nut wing runs through empty and is supported with a concave shoulder on a threaded bushing during the idle stroke. When the lock is blocked, a person can therefore press the lever handle from the outside without unintentionally acting on the lock mechanism and damaging it. This also results less stress on the nut and the square handle and a corresponding extension of the service life of the lock and fitting. The visual impression of a pusher hanging from the load is also improved by the invention, since this disadvantage no longer occurs.

Due to the design, permanent energization of the solenoid is no longer necessary. Rather, the energization takes place in the millisecond range, during two pulses, namely with the pulse "falling falling leg" and pulse "falling falling leg back". As a result, little energy is inevitably required and the lifespan of a battery installed in a fitting is increased considerably.

The nut is equipped with a central disc to prevent the split lever from being pushed through. The internal nut wing is used for direct actuation of the latch and at the same time for actuation of the entire anti-panic function.

The invention can also be applied with particular advantage to the anti-panic lock which can be found in German utility model G 91 04 766.8. Here the lock can be used especially indoors be used when e.g. B. a door equipped on both sides with a handle should not be used by unauthorized persons from the outside, while you can leave the room from the inside at any time.

Furthermore, such locks can be equipped with sensors or limit switches that 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 using a lock according to the invention in connection with an electromagnetic blocking in the escape route security. Only by triggering an alarm, e.g. B. emergency button, smoke fire alarm systems, alarm systems or the like, the blocking is released and the escape route is released.

DIN 18 251 provides a hole 46 mm above the center of the nut, which was usually intended for fastening fittings, but is generally not used. There are also drilling templates for this. The invention enables simple mounting of the power supply in that a miniature plug connection can be coupled within the lock through this hole to the power supply, so that no special milled or Holes are required to produce the power supply. In the lock according to the invention, the bore can therefore be selected 46 mm above the center of the nut. This hole is covered by the fitting. The power supply from the battery can therefore be installed via the plug connection already described underneath the fitting without additional effort.

The lifting magnet can be attached to a brass or plastic part for insulation reasons.

The plug part can be divided into a plastic socket and a two- or three-pole miniature plug. The miniature bushing is fastened in the plastic bushing by means of a hexagon nut or the like. The wiring between the solenoid 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 external and is only connected (inserted) when the fitting is installed.

Furthermore, a lock according to the invention can advantageously be used in a lock according to the German utility model that goes back to the applicant Use G 92 07 865.6, because when the drop end of the driver cam is actuated, it now lies non-positively behind the inner nut wing and the retraction of the latch and bolt latch can take place as in the German utility model G 92 07 865.6.

As already described, the lifting magnet or a hinged armature magnet, a relay or the like is in the de-energized state in the rest position (outer pusher idling). The non-neutralized permanent magnet now holds it in this position. With the anti-panic function and a change, the lock can always be opened from the inside. In the event of an accident, e.g. B. Power failure of the battery, the emergency opening by the master and emergency key can be carried out via a locking cylinder even when the bolt is locked. In principle, a half cylinder is sufficient for this.

In claim 2 a lock is described in which a lifting magnet is provided, which swivels the movable drop shaft via a pin into the effective area of a lever of the outer nut half, so that when Press down the door handle, the latch is taken along with the change, the bolt is also taken and the door can also be opened from the outside.

Claim 3 describes a preferred embodiment of the invention.

In claim 4 an embodiment is described with a hinged armature magnet, while claim 5 describes a construction according to the invention with a permanent magnet.

In claim 6 , the design of the nut halves is described.

According to claim 7 , the nut halves for right / left use of the lock are arranged interchangeably and connected to one another by a simple plug connection.

Claim 8 describes the special design of the trap.

The reference numeral 1 designates a lock plate, and 2 a lock cover, while 3 represents a cuff that is orthogonal to the lock plate 1 and has an opening for a latch 4.

Reference number 5 denotes a nut wing for the inside and reference number 6 a nut wing for the outside of the door to be locked (not shown) (FIGS. 11 and 12).

A nutshell has the reference number 7, with which the two nut wings 5 and 6 are coupled very precisely by a simple plug connection. The nutshell 7 also has a square opening in the center for receiving a pusher mandrel, not shown. A disc 8 (FIGS. 13 and 14) is arranged between the two nut wings 5 and 6 and in a central recess in the nut shell 7, 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 that the nut and thus a pusher pin in the 1 shows the position shown. The reference numeral 10 denotes a movable falling shaft, 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 rotates empty when actuating the outer lever against the force of the counter spring 25 by up to the stop against a threaded bushing 18, which is in the lock case, preferably between the lock plate 1 and the lock cover 2 is immovably stored.

A magnetic or chip card in the manner of a credit card triggers an approximately twenty millisecond lasting pulse via a card reader (not shown) and the corresponding electronics when the card in question is inserted into a slot (not shown) of a fitting part (also not shown). As a result, a permanent magnet is neutralized in the lifting magnet 14, whereby a pin part 29 has a stroke of z. B. executes about 2.5 mm. The pin part 29 strikes a lever 11 of the movable drop shaft 10, the design of which can be seen particularly clearly 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 drop shaft 10 falls into its actuation position, in which it engages behind a lever 31 of the nut wing 6. The end of the trap head of the movable drop shaft 10 is now offset by a few tenths of a millimeter in front of the lever 31 of the outer nut wing 6. At the same time, there is a driver cam 32 which projects orthogonally to the underside of the movable drop shaft 10 and is integrally connected to the movable drop shaft 10 and with a few tenths of a millimeter of play behind the end face 33 of the inner nut wing 5. When the trigger pin is pressed down, the latch is taken away and withdrawn into the lock case.

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

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 for an electromagnet, shown as a lever, is shown, while 16 relates to a mounting bracket for the lifting magnet 14.

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

In the case of short, wide and long signs, these are the holes 21.5 mm below the center of the nut and below or above the lock case. DIN 18 251 provides for a 46 mm hole above the center of the nut, which is usually not used for fastening fittings.

Due to the present construction and the space-saving construction of a miniature plug connection within the lock, it is possible to create a position for the plug connection which is favorable from the position. For this Position in the present case, the hole was selected 46 mm above the center of the nut. This hole is covered by the fitting. So it makes sense to install the power supply from a battery (not shown) integrated in the fitting via the described connector without additional effort below the fitting.

Towards the castle ceiling, the cylindrical pin 13 penetrates the movable drop shaft 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 drop shaft 10 always runs freely and cannot get caught between the catch 4 and the cover 2.

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

The plug part 27 is divided into a plastic socket and a two or three-pin 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 external and is only connected (inserted) when the fitting is installed.

The trap 4 is designed in one piece as a beam trap. The falling shank serves to receive the cylindrical pin 13 which, for. B. can be 4 mm thick and which extends through an elongated hole 37 of the movable drop shaft and slightly protrudes from it. 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 the like, but other materials that can be precisely manufactured. 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 drop shaft 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 the Engagement and turns empty when actuating the outer handle against the force of the counter spring 25 through to the stop on the threaded bushing 18. This means that sensitive parts of the lock device are not loaded. If a magnetic card or chip card is read in via a card reader, the electronics receive a pulse of approximately 20 milliseconds. 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 falling shaft 10. Against the force of the spring 23 and supported by the top-heavyness, the moving falling shaft 10 falls into an actuating position. The end of the trap head of the movable dropper shaft 10 lies in front of the outer nut wing 6, at the same time the driver 32 of the movable dropper shaft 10 lies behind the inner nut wing 5 taken away. When the drop end is actuated, the driver cam now lies non-positively behind the inner nut wing 5. The retracting movement of latch 4 and bolt latch can be carried out as described in German utility model G 92 07 865.6.

An elongated hole 37 in the movable latch shaft 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 starting position, the movable drop shaft 10 is still in the swivel range of the outer nut wing 6.

In the event of a further pulse, which is determined variably in the electronics, the lifting magnet 14 picks up, at the same time the movable drop shaft 10 pivots back into its starting position, supported by the tension spring 23.

With the door closed and the bolt locked, the lock can always be opened from the inside using the anti-panic function. From the outside, however, the handle turns empty.

In its rest position, the magnet 14 is deenergized because the outer handle runs through empty.

The embodiment according to FIG. 19 differs from the previously described embodiment in that a tension spring 38 holds the movable drop shaft 10 in its basic position I.

After energizing the hinged magnet, the switching lever 39 pivots from position A to position B. Via the cam of the movable drop shaft 10, the latter 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). With a further impulse, the tension spring 38 pulls the movable drop shaft 10 back into its basic position I. The switching lever of the hinged armature magnet 14 lies below the grooved mandrel, so that it can slide over the switching lever 39 when the latch 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 drop shaft 10. Opposite this, a permanent magnet 40 is also fastened on 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 drop shaft 10 is always in position I due to the magnetic field. By energizing the coil of the electromagnet the magnetic field is reversed and the movable drop shaft 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 spring 4 leading spring 4, the movable falling shaft 10 is pulled into the area of the magnetic field which is now repelling itself again, the basic position is thereby achieved again.

The features described in the abstract and in the claims as well as in the description and apparent from the drawing can be essential for realizing the invention both individually and in any combination.
