The new thing is that two parallel at the extreme end in the key shaft hinged beards arranged side by side, but independently of each other when the Key in the keyhole socket with its toothed parts on a toothed square mandrel push and comb with this, that a third hinged beard through one on the key

self-arranged adjusting device displaceable, as is also foldable at the same time and is turned into a plane perpendicular to the plane of the other two beards. The drawing illustrates an embodiment, namely shows:

Fig. Ι a longitudinal section through the key along the sliding hinged beard with beards laid down,

ίο Fig. 2 a view corresponding to Fig. ι with beards folded out,

Fig. 3 a section along the other two beards through the key with laid down Beards,

Fig. 4 is a view corresponding to Fig. 3 with the beards folded out,

Fig. 5 shows a cross section through the key with the beards folded out, Fig. 6 is an external view of the key with the beards laid down, i

Fig. 7 a cross section of the keyhole socket,

Fig. 8 an interior view of the lock on a reduced scale,

Fig. 9 is an external view of the keyhole, socket with an inserted key and folded out Barten, 'Figure 10 is a longitudinal section through _the. Socket and the toothed square mandrel. The key consists of one with the! Key ring 2 firmly connected square; shaft i, in which the movable rods 3 are stored in corresponding slots on two sides. At the upper end these are firmly connected by the axis 4, which is provided with two buttons 5. The other ends | the rods 3 are worked out to form a reinforced slide attachment 6 and are connected by the screw 7, which serves as the axis of rotation for the beard 8. A sliding movement of the axis 4 within the recess 10 of the shaft brings the beard 8 either into the position shown in Fig. 2 or in Fig. 1 under the action of the teeth 11 firmly attached by the screws 12 in the key shaft Position of the beard 8 according to Fig. 2 a her- | unfold the two beards 13 ahead. The- _; This is done by combing the toothed 'part 14 of the beard 13 with the toothed,; in the lock firmly attached square mandrel 22, j with the teeth 13, the screws 15 serve as axes of rotation.

The mode of operation is as follows: The key is in the position according to \ Fig. I, 3 or 6 in the key opening 17:

the rotatable sleeve 18 inserted, it should be noted that the protruding parts of the three bits 8 and 13 beyond the circumference of the key shaft 1 into the slots 19 get in. The toothed parts 14 abut the toothed square mandrel 22, mesh with this by pressing the key ring 2, and so the beards 13 step in the opposite direction Directions through the openings 20 in the keyhole socket 18 via the Scope of the latter addition (Fig. 9). By pushing buttons 5 to the lock too, the toothed part 9 of the beard 8 encounters the toothed part of the stuck Rod 11, combs with this, and by placing the beard in the recess 16 in the key shaft moved forward and at the same time rotates about the axis 7, it passes through the opening 21 the socket 18 in an angular position to the two other already unfolded beards, too beyond the circumference of the socket 18.

When the key is turned, the in Fig. 8 is moved in the reduced size Scale, without the lock mechanism shown corresponding to the key bits 23, the rotatable sleeve 18 taking part in the movements of the key.

The key can be removed without difficulty by first pulling it out the button 5, the beard 8 moves backwards and lowers, then the beard 13 can be lowered by pulling on the key ring 2.

An unintentional raising or lowering of the beard is prevented by drag springs.
