DE384465C - Chubb lock with main and pre-locking - Google Patents

Description

The subject of the invention is a Chubbschloß with main and pre-tumblers, of which the former are only used to block the bolt, the latter, however, as locking tumblers for the bolt, the main tumblers and the key. The key is designed as a digger ■ and turnbuckle key and when inserted has the effect that by means of special wedge surfaces coming in front of the beard to act ίο the front or locking _r tumblers by means of piston-like resilient intermediate members from the notches previously in engagement with them Bolt and: the main tumbler are lifted and the path is released for complete rotation of the ■ key bit, which sets the bolt and main tumbler in motion for the passage of the bolt lock pin.

Fig. Ι shows a Chubbschloß according to the invention in the locked position of the bolt with locked main and locking devices,

Fig. 2 with locking or locking tumblers opened after inserting the key.

Fig. 3 and 4 show the locks for the key entry on the lock cover before and after inserting the key.

Fig. 5 shows the trigger and rotary bit key in a single view.

The two-turn bolt c in the present case is in a known manner under the action of the larger number of main tumblers d, which influence the bolt locking pin and which are lifted by the key bit i (Fig. S) and open and close for the passage of the bolt locking pin f (Fig. ι and 2) are released. In addition to the locking organs a ", b '", c " (Fig. 3 and 4), the ends of the radially guided piston-like intermediate organs a, b, c (Fig. Ι and 2), which under the action of the tumbler springs, enter the keyhole with their ends protrude into the keyhole and, after inserting the key, rest against the back of the wedge surfaces h located in the corresponding number on the key shaft g . With their free ends, the pistons a, b, c lie against the tumblers a ″, b ", c", of which the tumbler α "is in the path of the key bit i (Fig. 5), while the tumbler b" latches into the notch b 'of the bolt c, tumbler c " in corresponding notches c of the Hauptzuhalteneu d After inserting the key g · first the rising wedge surfaces h of the key bit § ■ lie against the ends of the pistons a, b, c, which are mounted radially to the key shaft, and move them so far outwards; that the tumblers b " • and V- with notches b ', c of the bolt e and the main tumbler d disengage and the key bit i is released for one full turn.

This has ".. the effect that both the main tumblers d and the bolt e, both of which were previously blocked against unauthorized access, are unlocked so that the main tumblers can be lifted when the key bit is turned and can be released for the bolt lock pin to pass through so that only now the bolt can be moved into the locked and open position under the action of the key.

To make unauthorized access particularly difficult, the lock cover is also secured by locks in the key entry 8u (Figs. 3 and 4), which consist of bolts a '", V", c " which, under the action of the springs 1 , 2, 3 standing, protrude into the keyhole and are removed from the area of the keyhole through the wedge surfaces /} when the key is inserted.

Claims (1)

Patent claim: Chubb lock with main tumblers and tumblers, characterized in that the latter serve as locking tumblers for the bolt, the main tumblers and "the key, which as a trigger and turn-bit key by means of special wedge surfaces the tumblers (a, b, c) by resilient intermediate links from notches ( e ', d') of the bolt and the tumblers first lifts and releases the path for the rotation of the key bit, which then only lifts the main tumblers and the bolt for the passage of the bolt locking pin, moves. 1 sheet of drawings.
