Description

Security locks with chubb-like tumblers according to patent 341778 two key attacks for closing through one and the same keyhole can be used for two- and multi-turn locks for closing from one side as well as from both Pages are designed with three or more key attacks, with the tumblers shifting with the bolt be set by the key so that the key attacks used when closing after closing are inaccessible from the keyhole in the lock case. This increases security for two-speed and multi-speed locks given, and 'the possibility of variation is great.

The drawing represents in Figs. 1 and 2 a two-turn lock with a group of tumblers in view and section. Figs. 3 and 4 show a lock with two tumbler groups with the same representations. Figs. 5 and 6 show a two-turn lock for closing both Pages in elevation and · section.

The. Tumbler group b, which can consist of any number of tumblers, leads with slots c over pins d, which sit on the bolt α. The locking pin f located in the lock case engages as usual in the window e , which has a number of notches corresponding to the number of key attacks. There are three key attacks x, y, 2 arranged side by side, and the key, indicated by dashed lines, to be inserted via the mandrel g , which is designed as a double-bit key, successively lifts the tumblers out of the blocking position opposite to the action of the pins on the bolt i laying springs h out, shifts latches and tumblers at the same time. There is one key attack after the other in front of the keyhole, while the key attacks not attacked by the key are hidden outside the keyhole area in the lock case. The individual key attacks are the same for a single-bit key, and different for a double-bit key, so that the first key attacks χ again match the last, 2.

For locks with two tumbler groups; the one in fig ¹ . 3 and 4 shown embodiment, which from one side through the same keyhole, and

Claims (6)

one and the same double-bit key are operated, the individual key key attacks of the two guard groups can have an order analogous to the first embodiment, in such a way that the first groups of key key attacks have a different order than the second and the third groups match the first, so that the lock with two turns ίο is to be closed with a key with two double bits, one of which corresponds to the first double bit and the second double bit of the second opposite group of key-key attacks. The key attack groups can also coincide crosswise in their order, namely the first two key attack groups, while the third pair of key attacks again corresponds to the first pair. In the case of locks to be closed on both sides according to the third embodiment (Figs. 5 and 6), one of the number of key-key attacks corresponding to any number of key-key attacks to be classified through the keyhole on one side is arranged on the same tumbler group, which opens through a keyhole offset from the first keyhole the other side of the lock. For •) o a single-turn lock that can be closed on both sides, each tumbler group is provided with four key attacks (in Fig. S these are attacks 1 to 4). In the case of two-speed locks that lock on both sides, on the other hand, each tumbler group has six key locks. Since a spring acts on each side of all these tumblers, they follow the action of the key from all points, and the arrangement of the key locks used to close from one side and those used to close from the other side can also be used Attacks in relation to the locking groove (window) of the guard locking are designed symmetrically. Godfather NT-A κ Proverbs: 1.Safety lock according to patent 341778, ■ characterized in that the tumblers each with three or more key attacks are equipped. 2. Safety lock according to claim 1, characterized in that when furnished with a group of tumblers each with three key attacks to close from one side the first group of key attacks has a different order of any kind than the second and third groups coincide with the first, so that the lock It can be locked in two turns with the help of a double-bit key, one of which belongs to the first group and! its second Bart corresponds to the second group of key attacks. 3. Safety lock according to * claim 1, characterized in that when set up for closing from one side with two opposite sides Groups of tumblers with three keys each attack the first two opposing key attack groups can have any order and deal with the following attack group pair cover crosswise in the order, while the 'third pair again corresponds to the first, so that all groups in two-speed locking with the same double-bit key that the first Attack group pair closes, be classified. 4. Safety lock according to claim 1, characterized in that on both sides to lock any number of locks through the keyhole Another number of key attacks on the guard locking corresponding to the key attacks to be classified on one side is arranged, which is offset by a against the first keyhole Keyhole can be used on the other side. 5. Safety lock according to claim 1, characterized in that on both sides to close locks and one who joins the bolt movement With single-speed locking, each guard locking is set up with four key attacks and with two-speed locking, each guard locking with six key attacks Is provided. 6. Safety lock according to claim 1, characterized in that the tumblers are pressed on both sides by springs against a tumbler pin each, thereby preventing the action of the Follow the key from all points, and the order of the key attacks used to lock from one side and also the attacks used to close from the other side in relation to the locking groove of the tumbler can be designed symmetrically. 1 sheet of drawings.
