Gegenstand der vorliegenden Erfindung bezieht sich auf ein Schloß, das das Öffnen der Tür von einem beliebig entfernten Punkte des Zimmers aus ermöglicht. Es sind bereits Schlösser dieser Art bekannt geworden, deren Öffnen dadurch erfolgt, daß ihr Riegel mit Hilfe eines Winkelhebels und einer Zugvorrichtung aus der Ferne zurückgeschoben wird, doch sind diese Schlösser insofern mangelhaft, als der bei ihnen unter Federwirkung stehende Riegel in seiner Offenstellung nicht selbsttätig, sondern dadurch festgelegt wird, daß die Zugvorrichtung mittels eines in bestimmter Höhen- oder Weitlage angebrachten Ringes in einen Knopf eingehängt wird, welcher Ring jedoch infolge der durch die beständige Spannung eintretenden Dehnung der Zugschnur oder dergl. Vorrichtung seine Lage in nachteiliger Weise verändert, während die Zugschnur selbst häufig reißt.The present invention relates to a lock that allows opening the door from any point in the room. There are already Locks of this type become known, the opening takes place in that their bolt with Is pushed back remotely with the help of an angle lever and a pulling device, but these locks are defective in that they are spring-loaded standing bolt in its open position is not automatically, but is determined by it, that the pulling device is attached by means of a certain height or distance Ring is hooked into a button, which ring, however, as a result of the constant tension occurring elongation of the pull cord or the like. Device its Position changed in a disadvantageous manner, while the pull cord itself frequently breaks.

Vorliegende Erfindung besteht nunmehr darin, daß der in bekannter Weise mit dem Riegel zwangläufig verbundene und diesen durch sein Gewicht in seine Schließstellung führende Winkelhebel in seiner der Offenstellung des Riegels entsprechenden - Lage durch ein sich beim Anziehen der Zugschnur unter ihn legendes Hindernis festgelegt wird, das beim weiteren Anziehen der Zugschnur selbsttätig aus der Bahn dieses Winkelhebels heraustritt und dessen freies Niederfallen bezw. das Sperren des Riegels zuläßt. Durch diese Anordnung ist einesteils ein Zerreißen der stets schlaff liegenden Zugschnur sozusagen ausgeschlossen, andernteils die Wirkung des Schlosses auch bei Dehnung der Zugschnur gesichert. Jegliche mehr oder minder rasch unbrauchbar werdende Federung des Riegels ist außerdem vermieden.The present invention is now that in a known manner with the Bolt inevitably connected and this due to its weight in its closed position leading angle lever in its corresponding to the open position of the bolt - position is fixed by an obstacle lying under him when the pull cord is pulled, that when the pull cord is tightened automatically out of the path of this angle lever emerges and its free falling bezw. the locking of the bolt allows. By this arrangement is, on the one hand, a tearing of the pull cord, which is always slack, so to speak excluded, on the other hand the effect of the lock is secured even if the pull cord is stretched. Any more or Suspension of the bolt, which becomes unusable less quickly, is also avoided.

Der im Schloßgehäuse 1 untergebrachte Riegel 2 ist einesteils in kurzen Ansätzen des Stulpes, andernteils auf einer Rolle 3 horizontal verschiebbar gelagert, die entlang einem Führungsschlitz des Riegels läuft. Zum Vorschieben (Sperren) und Zurückziehen (Öffnen) des Riegels dient der um Zapfen 5 drehbare Winkelhebel 6, dessen einer Schenkel mit einem Stift 7 in einen vertikalen Führungsschlitz 8 des Riegels greift, während sein anderer Schenkel 6' durch ein Gewicht 9 belastet ist und als Angriffspunkt für die über Rollen 11 bis zur gewünschten Stelle des Zimmers geführte Zugschnur oder dergl. dient.The bolt 2 housed in the lock housing 1 is partly in short approaches of the Stulpes, on the other hand mounted on a roller 3 horizontally displaceable along a The guide slot of the bolt runs. To advance (lock) and retract (open) the bolt is used to rotate about pin 5 angle lever 6, one of the legs with a pin 7 engages in a vertical guide slot 8 of the bolt while being other leg 6 'is loaded by a weight 9 and as a point of attack for the over Rolls 11 to the desired point in the room, guided pull cord or the like.

Claims

Angle lever 6 held. It is not difficult to see that by tightening the pulling device in the direction α (Fig. I) the bolt 1 is pushed back, d. H. the lock can be opened, but after releasing the pulling device, the angle lever would automatically cause the bolt to advance (lock) again. To avoid this, i. H. In order to keep the bolt in its open position until the door is locked, even after the pulling device has been released, the device shown individually in FIGS. 2, 3 and 4 is now arranged according to the present invention. This consists of a housing 14 fastened to the lock plate 13, which is provided with a small spoon-like shell 16 which can be loosely rotated about pin 15 and in which a ball 17 is loosely located, which, when the shell is raised, passes through a corresponding opening in the housing wall 18 and thereby the path between this wall and the cover plate 19 - which serves as a guide for the arm 6 'of the angle lever - blocked. The mode of operation of this lock is as follows: The angle lever 6 lies with its arms 6 'when the bolt is locked in the lower part of its mentioned guide (FIG. 3). On this arm 6 ', a short arm 21 is articulated around pin 20, which is prevented from moving upward in any known manner, for example by a joint stop, and can only move upward. If the angle lever is now rotated around its pin 5 by tightening the pulling device 10, the arm 21, which grips through a slot in the side housing wall, strikes a lateral, correspondingly shaped stop 22 of the shell 16 and lifts the shell so far that when it is pushed back (opened ) Bolt the ball 17 comes to lie under the arm of the angle lever mentioned (Fig. 4) and thereby prevents the angle lever from turning back and thus prevents the bolt from automatically jumping forward when the pulling device is released. The individual lock parts then assume the position shown in FIG the shell releases, fall back by itself to its previous position. To do this, respectively. in order to lock the bolt again, only a slight pull is exerted again in the direction α (Fig. 1) on the pulling device, whereby the angle lever and bolt automatically move into their closed position. A strong spring 23 resting against the stop pin 24 has the purpose of indicating the open position of the bolt by increasing the pulling resistance when the angle lever strikes the spring with its arm 6 '. It should be noted that the lock is designed as a box or mortise lock and can be used for both right and left-hand doors by simply reversing it. Godfather T-A ν Proverbs:

1. Lock with one of any remote places by means of a pull cord and Angle lever retractable bolt, characterized in that one arm of this angle lever is in its open position of the bolt corresponding position is determined by an obstacle lying under him, the further Tightening the pull cord automatically emerges from the path of this arm and the free fall of the angle lever BEZW. the locking of the bolt allows.

2. Embodiment of the lock according to claim I, characterized by a spoon-like bowl (16), which is in a against the guide of the arm (6 ') of the Angle lever to open housing (14) is rotatably mounted, for receiving a Ball (17) is used and when lifting the angle lever with the help of this attached arm (21) pushes the ball into the guide of the angle lever and the latter fixes, while in the further, expediently by a spring (23) made it difficult to tighten the angle lever, the shell is free from the aforementioned arms (21) and together with the ball automatically falls back into its normal position, so / let it through in the known way a weight-weighted angle lever fall down and the bolt in the closed position can move.
