Description

KAISERLICHESIMPERIAL

Die Erfindung betrifft ein Sicherheitsschloß, welches nur mit dem dazugehörigen Schlüssel, keinesfalls jedoch mit einem Nachschlüssel oder einem anderen Instrument geöffnet werden kann. Dabei zeichnet sich das Schloß vor bekannten Ausführungen durch große Einfachheit aus und kann von jedem Laien an der Tür o. dgl. angeschlagen werden.The invention relates to a safety lock which can only be used with the associated key however, under no circumstances should it be opened with a duplicate key or any other instrument can. The lock is characterized by great simplicity in front of known designs and can be posted on the door or the like by any layperson.

Das Schloß enthält in bekannter Weise einThe lock contains in a known manner a

ίο mit dem Schlüssel zu kuppelndes, im Ruhezustande durch eine Feder gesperrtes, zur Drehung des Riegels dienendes Zahnrad, dessen Eigenart darin liegt, daß das Zahnrad durch die unter ihm befindliche Feder mit Sperransätzen der letzteren im Eingriff gehalten wird, so daß sich das Zahnrad frei drehen kann, wenn es durch einen Druck des Schlüsselschaftes auf die Zahnradfläche außer Eingriff mit den Sperransätzen kommt. Dabei treten die in bekannter Weise zur Kupplung mit dem Rade dienenden Schlüsselstifte, falls sie zu lang bemessen sind, in Aussparungen der Feder ein und verhindern somit in diesem Falle eine Drehung des Schlüssels. Es läßt sich also das Schloß nur öffnen, wenn einesteils der Schlüssel für das Schloß passende Stifte trägt, und wenn andernteils letztere nur gerade so lang sind, daß sie durch eine über dem Zahnrade liegende, die gleichen Aussparungen wie letzteres tragende Deckplatte und das Zahnrad hindurchtreten, ohne in die Aussparungen der Feder einzugreifen. Nur in diesem Falle wird nämlich, sobald der Schlüssel mit der Deckplatte und dem Zahnrade in Eingriff gekommen ist, die Feder derart nach unten gedruckt, daß ihre Sperransätze das Zahnrad freigeben, wodurch dessen Drehung und damit .ein Vorschieben des Riegels möglich wird. Sind die Schlüsselstifte zu kurz, so dringen sie nicht in das Zahnrad ein und vermögen es naturgemäß dann auch nicht mitzunehmen; sind dieselben j edoch zu lang, so erfassen sie die Feder mit, und daher kann sich der Schlüssel nicht drehen, weil die Feder in einer Führung festliegt. Auch durch die verschiedene Länge des Führungsstiftes für den Schlüssel lassen sich Variationen schaffen, und da schließlich die Schlüsselstifte in bekannter Weise mannigfach Querschnittsformen erhalten und unter verschiedenem Winkel zueinander angeordnet werden können, so ergibt sich, daß keine Gefahr besteht, daß ein nicht für ein bestimmtes Schloß angefertigter Schlüssel zur Öffnung desselben dienen kann.ίο to be coupled with the key, in the idle state Locked by a spring, for the rotation of the bolt serving gear, whose The peculiarity is that the gear wheel through the spring located under it with locking lugs the latter is kept in mesh so that the gear can rotate freely, when it disengages from the pressure of the key shaft on the gear surface comes with the locking approaches. This occurs in a known manner for coupling with the Rade serving key pins, if they are too long, into recesses in the spring and thus prevent the key from turning in this case. So it leaves the lock only open if, on the one hand, the key for the lock has matching pins, and if so on the other hand, the latter are only just long enough to be replaced by a the same recesses as the latter supporting cover plate and the gear pass through, without reaching into the recesses of the spring. Only in this case will once the key has come into engagement with the cover plate and the gear, the Spring so pressed down that their locking lugs release the gear, whereby its rotation and thus .a advancement of the bolt is possible. Are the key pins too short, they do not penetrate the gear and are naturally able to do it not to take with you; but if they are too long, they grasp the pen with, and therefore the key cannot turn because the spring is stuck in a guide. Also through the different lengths of the guide pin for the key can be varied, and finally there are the key pins in a known manner in a variety of cross-sectional shapes can be obtained and arranged at different angles to each other, so results that there is no risk of a key not made for a particular lock can serve to open the same.

Claims

produced and provided on the bottom with two supports b, c, which leave a gap between them and of which the latter is bent in such a way that it encloses a rectangular space with a box wall, j, which receives the lock bolt d. In this attached teeth e engages in a known manner around .den pin / rotating gear g, under which in the gap left by the supports b and c ίο the leaf spring i provided with locking lugs h, which, as in FIG. 3 shows, . rests in the rest state only in two places on the lock case base, while their on. blocks mesh with the gear. On the latter there is the stronger, suitably circular recess in the middle that has a corresponding key shaft thickness. Plate k, which is intended to protect the gear from damage. From FIGS. 1 to 3 it can be seen that there are recesses Z in this plate as well as in the gear wheel g and the leaf spring i, which cover in a certain position of the parts mentioned and for the introduction of the on which also a bore m for the key shank η containing the guide pin f, pins 0 are used. If the bolt d is in the rest position (FIG. 3), the leaf spring i lifts the gear wheel g and the plate k so that their lugs h engage the teeth of the former. So it is now utterly impossible to shift the bolt. If, however, the key that fits the lock is inserted with its pins into the recesses of plate k and, after a certain rotation of the latter, into those of gearwheel g, and then pressure is exerted against spring i, the lugs release the gearwheel (Fig. 1 and 2), whereupon this advances the bolt d when it is rotated in the direction of the arrow according to FIG. The lock is opened in a similar way, but the same can only be done with a very specific key. If the pins 0 are too long, they engage in the recesses in the spring i, thus preventing the gear wheel from rotating; if they are too short, however, they cannot grasp the latter at all, and the bolt also remains in its position. In FIGS. 6 to 9 different key shapes, which do not offer anything new, are shown in a bottom view, in order to show that the design of the key shaft, the bores m and the pins ο a special key for each lock, which only fits this one, can be produced. Since, as already mentioned, the pin length is also important and the change in the depth of the bore m. Or the height and cross-sectional shape of the pin f and the setting of the pins at different angles and changing distances from the key rotation axis result in further variations it can rightly be doubted that a key will ever be used by someone else, i. H. cannot open a lock that has not been worked for him. This lock can be attached to any box, door, etc. without difficulty, since it is only necessary to drill a hole for the introduction of the key, while the lock itself, as can be seen from FIGS. 2 to 4, to the smoothness. Box wall or the like. Is posted. It is advisable to let the lock bolt enter into a guide equipped with a drag spring on the immovable box frame, 0. Pa τ ε ν τ - A ν s ρ rü c η ε:
