In the case of the present combination lock, the is usually replaced by a Key to be moved and provided with a guard locking bolt by a the cross bolt lying inside the lock, on which the combination device, consisting of several disks that can be rotated independently of each other with one, cut, acts in a known manner. The kinematic connection of the guard locking is new here the lock bolt with a locking device for the cross bolt on the one hand and the cross bolt with a locking and adjusting device for the disks of the combination device, on the other hand, whereby the connected parts in their movement are made dependent on each other and the security of the lock is increased.

In the accompanying drawing, Fig. 1 is a view of the lock with the ceiling removed, Fig. 2 is a vertical section and Fig. 3 is a horizontal section, the latter along line 3-3 of Fig. 1. Fig. 4 shows a piece of the door T. the castle from the outside. The remaining figures are special views, namely Fig. 5 is a front view, Fig. 6 is a side view of the cross bar, Fig. 7 shows one of the panes and Fig. 8 shows one of the plates alternating with the panes, each in a front and side view.

In the lock box A we first find the lock bolt B (Fig. 1 and 2). The guard locking (humming iron) b acts on the bolt; the incisions for the same and the key attack correspond to a two-turn bolt. 'The key C can be of any type; According to the drawing, the bolt, tumbler and key are taken from an ordinary French lock.

When the bolt is fully advanced, the pin d on B lies in front of the raised cross bolt D, but goes freely over the pushed down cross bolt. In the middle position (first tour) of B , pin d lies at d ¹ (Fig. 1 dotted); the lock bolt can therefore be pushed into the first tour despite the raised cross bolt without the pin d being brought into disruptive contact with the cross bolt.

The cross bar D, which is guided vertically in a suitable manner on the floor of the castle, can be moved by means of the toothing ^{d 2} and the toothed drive d ³ ; on the drive axis d * sits the handle d ^h outside the door (Figs. 2 and 4). Drive d ^s is blocked in the idle state by pawl d ⁶ , which is articulated to tumbler d by rod ^{d 1.} Accordingly, the cross bar can only be moved when the key bit C has lifted the tumbler b and with it the pawl d ^6.

The bolt e ^{is located below the tapered foot section D 1 of} the cross bar, which extends through the entire clear thickness of the castle. On it are alternating with the plates e ¹

Claims (1)

the toothed disks E are loosely lined up. With their thickenings e ³ lying next to one another and held together by bolts e ² , the plates e ¹ allow the disks E with the laterally projecting pins e ⁴ scope for rotation, which is limited ^{by placing e 4} on e ^l. ' Under a Centriwinkel which is different in the various slices, lying to the pins e ⁴ emanating from a tooth gap radial incisions e ⁵ of the discs E. The discs E can independently of each other by the drive F on the hollow shaft are rotated f, f can be rotated and slid on the mandrel / ¹ and is provided with the handle / ² outside the door. A pawl / ⁴ , in conjunction with the incisions / ³ on /, sets the drive F in relation to each individual disk E. If the crossbar D can be pushed down completely, all the incisions e ⁵ must be directed upwards. A stop in the setting of the disks E by the pinion F is provided by a diametrical mark on f ² (Fig. 4) in cooperation with a circular pitch / ⁵ on the metal plate S corresponding to the tooth pitch of the pinion. Incidentally, the crossbar D and the washers E do not belong to the present invention. A pawl G under the action of the spring g , the head of which extends over all the disks E , is articulated to D by the rod g ¹ with a slotted head. If D is lowered, G first engages in the disks E ; but then, thanks to the slot in g ^1, the crossbar can go further downwards. Conversely, with the upward movement of the cross bar D in the last part of the movement, the small stick g ^{1 will be} carried along. There is an intermediate position of the crossbar in which it rests on the base of the teeth of E. In this position the lock bolt is blocked by D and G engages in E. The latch G has a dual purpose. Once she should just irish Thanks to the wedge shape of her head setting the wheels only at the Walking down the cross bar and then back up to the other it is to lock the wheels E is locked Castle of and d ³ <P in the intermediate position secured crossbar. This prevents unauthorized adjustment of the panes when the lock is locked, but then also makes it impossible to try in the direction that one could determine by raising and lowering the transverse bolt and simultaneously turning the panes to and fro, whether the foot of the transverse bolt is larger or less resistance. The drive F cannot be rotated as long as it engages in one of the locked discs; in order to secure F and f against unauthorized shifting too, the 'attachment g ^{2' is} attached to G (Fig. 1), which 'lies in front of the shoot when Ff is pushed as far as possible into the castle, so that F in the last disc E engages. According to Fig. 1, the lock bolt B is fully advanced, the cross bolt D assumes its highest position, pawl G is on the engagement with the panes. From this position you can secure the lock with the combination device. First, with the aid of the drive F, all or several of the disks E are adjusted. Then it lifts by means of the key, the tumbler b C so far, that pawl d ^ß the engine ³ d freigiebt. Now, through d ° -d ⁱ -d ^i, the cross bar D can be lowered so far that pawl G locks the panes E and the foot of the cross bar enters the tooth gaps of E opposite it. In this intermediate position, the lock bolt is blocked by D and d. The tumbler that snaps back into place allows ^{d 6} to intervene in d ^3. Crossbar and shoot are immobile. At the same time, G has also secured the disks E and attachment g ^2, the drive F pushed back. In order to open the lock again, the cross bolt is first brought into its highest position after the tumbler b has been raised and the drive d ^{3 has been released.} The misaligned disks E are set correctly, the initiate knows how far he has to turn each of them until it directs its slot upwards. So the position of FIG. 1 occurs again. All of the disks have their slits turned up. Now (after lifting the guard locking) the cross bar is pushed back all the way. First G comes in and adjusts the position of the disks, then D ¹ penetrates to the bottom of the slots or. so far that the head of the cross bar releases the pin d . The lock bolt can now be pushed back using the key. The lock described can also be used like an ordinary door lock. When the cross bolt is pushed back (engaging in the slots e ⁵ ) the lock bolt can be pushed forwards and backwards through both turns, with the cross bolt raised at least through one turn without having to adjust the combination device. Pat en τ claim: Lock with cross bolt and several combination disks acting on this to secure the lock bolt, characterized in that the cross bolt (D), which in turn, only after the tumbler (b) of the lock bolt has been lifted and the pawl (d ⁶ ) acting on the drive (d ^s ) to move the cross bolt - can be moved, with a locking device that adjusts the setting of the combination disks and with its approach (g ² ·) the drive (F) for adjusting the combination disks is connected to prevent shifting locking pawl (G) in such a way that when the cross bolt is pushed back, the pawl engages in front of the cross bolt.
