Fallen-Pahikschloßv especially for 'tubular frame doors ,

The invention relates to a latch panic lock intended in particular for tubular frame doors with an outer nut part rotatably adjustable by an outer handle, one coaxially arranged therewith, by an inner handle 'rotatably adjustable inner nut part and an engaging on the lock latch shaft Latch driver arm, in the sense of trap entrainment can be constantly acted upon by the inner nut part, but only via the outer nut part a coupling nose to be engaged, which is attached to a vertical movable and from a key-operated Shut-off device with adjustable coupling arm sits. With such a trap panic lock can the lock latch through the inner handle and the resulting Drehzüverstellide inner

Nut part at any time, including when the shut-off device is locked, e.g. in the event of a panic, be obtained, whereas the operation of the lock latch by the outside handhabe only with im unlocked state of the shut-off device engaged clutch nose is possible, otherwise the outer handle runs empty.

In a latch panic lock of the above type known from DE-GM 82 16 0S6, the one on the lock latch shaft attacking trap driver arm part of the inner nut part, which in turn has to be engaged Coupling nose is to be coupled with the outer nut part. For this, there are in comparatively short distance from their turning point Arranged driver socket, between which the coupling nose seated on the coupling rocker is pivoted can be, whereby the rotary drive coupling between the two nut parts is effected. Then will the coupling rocker also vertically by a distance corresponding to the rotary adjustment stroke of the two nut parts adjusted. In this previously known Falleri panic lock, there is the disadvantage that the coupling nose is engaged Condition between the inner and outer nut part squeezed like a pincer and therefore damaged can be, then namely when held up Inner handle the outer handle is pressed down. The resulting squeezing of the coupling nose can easily lead to proper engagement between the inner and outer nut part is no longer guaranteed, which is also particularly because of this can easily occur because the coupling nose together with the coupling rocker in the coupling case only performs a linear movement and therefore all the more more easily disengaged from the two rotating ones Share the takeaway ocher on the two nuts' comes.

-JlS-

The invention is therefore based on the object a Falleri panic lock of the type mentioned at the beginning to the effect that the '.above mentioned risk of crushing cleared for the coupling nose and the lock becomes more reliable in terms of operation and function. This object is achieved according to the invention in that a third, namely middle nut part rotatable: is arranged, which carries the trap — driver arm, with the outer nut part over the coupling nose to be engaged and with the inner nut part via driver cams is to be connected to rotary drive. This leads to a three-part lock nut the actuation of the lock latch is only ever via the middle one, which is provided with the latch driver arm NussteiT takes place and the Drehverstelantrieberi des outer and inner nut part completely independent from each other. Since the DrehversteTlbewegung of the middle nut part by the inner hand can in no case be blocked, there is a pincer-like squeeze between the middle one and the outer nut part - engaging clutch nose not possible anymore.

Advantageously, a return spring acts on the central nut part, which enables the inner as well as the outer nut part in the conventional one Way by a holding spring attacking them are applied and the interior handling when completed The shut-off device and the actuation of the outside hand that takes place in the process are not twisted is, whereby otherwise the lock latch would be overtaken and the shut-off device would be unlocked.

The Falleri panic lock advantageously has a key-operated shut-off device, which, as is known from DE-OS 29 14 ^: 372, consists of a sliding bolt secured by a tumbler plate and a sliding bolt that is partially movable with the latter and which, like the switching bolt, has latching incisions for key operation , but can also be actuated by the inner nut part in the sense of the sliding bolt retraction movement via a panic lever mounted so that it is difficult to move. Here, the invention provides that the coupling rocker is to be pivoted via a driver boom seated on the sliding bolt. This has the advantage that for the "key actuation of the coupling rocker" the conventional 'sliding bolt mechanism can be used in a correspondingly narrower design for the tubular frame door. . "

Further features of the invention are the subject further subclaims. '

The drawing shows an advantageous embodiment of a latch panic lock provided with a sliding bolt shown for tubular frame doors. Show:

The panic lock shown in FIGS. 1 to 3 has a lock box 2 which is firmly connected to the faceplate 1 and which is of a correspondingly narrow design for tubular frame fittings. In the upper part of the lock case, the lock latch 4 is slidably mounted in an opening 3 in the faceplate, which is additionally guided with its latch shaft 4 'and projections 4 *' on the side in the: Schloßkästeri 2 and in the lock case cover (not shown) in guide slots 5 . On the end plate 4 * '.' On the latch shaft 4 *. engages the upper part of the Fallerifeder 6, which ^{seeks to press the end plate 4 r} 'V against the housing-fixed stop pin 7 and thus also the latch in its extended closed position. In addition to the falling spring 6 wound around the housing-fixed bolt 8, a retaining spring 10 is arranged in the upper part of the lock case and is spirally wound around the housing-fixed square bolt 9, which strives to hold the retaining slide 11 leading to the lock nut parts in its upper position.

In the middle area of the lock case 2, three different nut parts are mounted coaxially one above the other and rotatably adjustable, namely the outer nut part 12 / the middle nut part 13 and the inner nut part 14 ^: The rotational adjustability of these nut parts is limited by the two bolts 15, 16 fixed to the housing.
