As shown in FIGS. 1 to 9, there is a cylinder 12 a cap 13 connected to it with an inwardly pointing annular flange 14 on its end face

109830/0057

on. A pin 15 is inserted into the bore of the cylinder, to be rotatably held therein by a closing plate 16 and a threaded ring 17 and the thread of the threaded ring cooperates with an internal thread at the rear end of the cylinder. The rear end of the cylinder can also be designed as an inwardly pointing flange and the cap can be removed at the end, to allow insertion of the tenon. The pin 15 is with a slot 18, another slot 20 of smaller width, which adjoins the slot 18, and a bore 21 is formed which leads to the base of the Slot 20 opens out. The front end of the pin is covered by an end cap 22 and the rear end 23 is of reduced diameter to extend through the locking plate 8 16. The rear part of the The base of the slot 18 is closed by a retaining plate 24 which protrudes into slots 25 engages the pin in order to prevent independent movement of the retaining brace. On the sides of the slots 18 bzui. 20 are holes 26 bzui. 27 provided in the pin, to include axes of rotation in it. The end cap 22 and the sides of the pin 15 form a stretched one Keyhole 28 lying transversely in the pin, the flange 14 of the cylinder cap being formed with a groove 30

109830/0057

which coincides with the outer end of the keyhole in the closed position. The keyhole has no flat parallel sides, but is with a number of recesses 31 in its sides profiled.

Six engaging lever 32 are fixed in a row in the slot to independently about a common axis of rotation ⁵ 33 to rotate from each other in the holes 26 and extend perpendicular to the axis 34 of the pin and the cylinder substantially parallel to the plane of the keyhole eccentric. The planes of the engagement levers 32 are essentially perpendicular to the plane of the keyhole, so that each lever points with a leading edge 35 towards the keyhole. Each engagement lever is provided with a spring 36, one end of which is attached around the pivot 33 and the other end of which is attached to the retainer plate 24, the spring being in a slot in the engagement lever to set the lever in a locked position adjacent the keyhole to press. The upper edge 37 of each engagement lever is cam-shaped and its rear edge is provided with a protrusion 38. This edge also has a recess 40 and the recesses 40 of at least some of the levers

1098 30/0057

different distances from the leading edge 35, as in dashed lines Lines shown in Fig. 1.

A switching claw 41 is rotatably mounted on a rotation axis 42 in the holes 27 parallel to the axis 33. One Spring 42A has one end mounted in hole 21, running around axis 42 into a slot in the Shift pawl 41 and its other end engages the rear side 43 of the shift pawl to remove it from the keyhole iueg into a latched position, in u / elcher their rear surface in a cam-shaped recess 44 comes to rest in the closing plate 16. The front of the pawl is with a forward protruding Arm 45 is provided which abuts against the projections 38 on the engagement levers and its front surface next to the edges 37 of the engagement lever is in their locked positions.

lliie from Fig. 10, the key 39 is with a side edge 46 and a front edge 47, the latter having six steps arranged are to abut corresponding engagement levers and the surfaces of the steps at different distances from the rounded front surface 48 of the side

edge 46 are arranged. The distances between the wells 40 in the engagement levers from their leading edges 35 is proportional to the distances between the leading edges 47 of the steps from the front surface 48.

When the mechanism is in the locked position, the pin passes through Engagement of the switching claw 41 in the recess 44 is prevented from rotating in the cylinder and the movement of the Shift claw from this latched position is through The arm 45 is prevented from hitting the upper edges 37 of one or more of the engagement levers. If the right one When the key is inserted into the keyhole, the stepped leading edge 47 of the key contacts the leading edges the engagement lever and moves it against the action of by means of a thrust as opposed to a stroke Springs 36 in an unlocked position in which all recesses 40 are aligned side by side, to accommodate arm 45 as shown in FIG. Rotation of the pin with the help of the key pushes the switching claw forward into its notched position, in which the arm 45 as a result of the interaction of the cam surface of the recess 44 with the rear of the Switching claw is brought into the recesses 40 against the action of the spring 42A. When the arm 45 of the

109830/0057

Switching claw is located in the recesses, the back of the switching claw slides on the flat / order surface of the locking plate, so that the pin can be rotated in both directions in the cylinder. If one of the steps on the key is Palscher Depth to position the front surface on its corresponding engagement lever, the indentations will not be in the correct position and the latch will not be able to disengage. By changing the depth and arrangement of the steps and handles, different lock combinations are of course provided. The side edge 46 of the key engages the edge 50 of the keyhole and through the groove 30 in the cylinder cap and restricts the lateral and longitudinal movement of the key, the opposite side edge 51 being flat. The side edge 46 is formed with a groove 52 to receive the cylinder flange 14 when the key is turned. The engagement of the edges of this groove with the flange 14 prevents removal of the key, except in the locked position of the mechanism. The profile of the key corresponds to that of the keyhole. Another arrangement of the shift pawl is shown in Figs. 11 and 12, in which a ball 53 at

109830/0057

the rear face of the pawl and engages recess 44 in the striker, the mechanism otherwise being the same as that previously shown.

As a result of the profile shape of the key and the keyhole, not all parts of the key that the The front edges 35 of the engagement levers touch, in the same plane u / ie from FIGS. 13 and 14 emerges. The levers that are operated by the key steps on the center line Z, have a lower U / angle adjustment per unit the key move as the levers that go through key steps be operated on the center line Y. This is inadequate because the touch of the key is specific Lever at the corner of the step is carried out, resulting in a wear and tear and a reduction in the Lever movement results. To rule this out, two different levers with differently shaped leading edges are used 35 is used, the lever shown in Fig. 13 works with the steps on the center line Z of the key together and the lever shown in Fig. 14 with the steps on the center line Y of the key so that all levers with the key steps are at or near the center line those stages will have touch. Another

Lever design that combines these two types shown in Fig. 1b.

As can be seen from Figures 16 to 1b, the pin, cylinder, lever and pawl of this arrangement are generally similar to those already described and are given the same reference numerals so that the same parts will not be described again. In this embodiment, the flange 14 of the cylinder is of greater depth and is formed on its inner surface with a recess 54 to receive a projection 55 which extends forwardly from the cap of the pin which is made in one piece with the pin. The introduction of the projection 55 in the recess prevents a relative rotation of the pin in the cylinder. The rear end of the bore of the cylinder is threaded as before and has a threaded ring 56 secured therein which receives the rear end 23 of the pin and is provided with an inwardly facing annular flange 57. A compression spring 5b around the part 23 of the pin acts between the flange 57 and the pin in order to push the same axially forward and to hold the projection 55 in the recess 54. The rear side 43 of the switching pawl is attached to an end face 60 of the gear by the spring 42A.

winder rings pressed. In dan locked positions of the shift lever 32, the switching claw is prevented and from pivoting forward by the abutment of its arm 4b at the edges 37 of the engagement lever 32 as long as the switching claw can not be / enkt forward geschu, the pin can not axially into the Cylinder are moved. When the correct key is inserted, the levers are pivoted, as above, into a position in which their recesses 40 are aligned to receive the arm 4b. In this position, a further pressure on the key pushes the pin axially into the cylinder and brings the arm 45 in the recesses until the projection 55 of the flange 14 geläst h ^ t and the pin can be rotated in the cylinder.

Another embodiment is shown in FIGS. 19-21. A cylinder 61, generally similar to the cylinder 12, has a cam-shaped recess 62 in its inner surface. A pin 63, generally similar to pin 15, is located in the cylinder for rotation therein and is of reduced diameter 64 which extends through a threaded ring 65 by which the pin is retained in the cylinder. A number of

Sliders 66 are in a row in a slot 67 arranged in the pin to have a word edge 68 on to lie against the keyhole 69 and slide parallel to the axis of the pin. A spring 70 is with each slide gate united. Each feather is around a common one in the pin 71 fixed in the pin wound, with one end supported on the inner surface of the pin and the the other end on the back of the corresponding slide to push it towards the keyhole. Everyone Slider is provided on its upper surface 73 with a recess 72, the function and the arrangement of the depressions 72 corresponds to those of the depressions 40. A shift pawl 74 is rotatable on one Axis of rotation 75 is mounted in the pin and has a rounded rear side 76 on its upper part 77, which in FIG in the latched position, engages recess 62 to provide anti-rotation movement between the pin and the cylinder to prevent.

One end of a spring 78 is supported against the rear side of the pin, runs in a slot in the shift dog around the axis of rotation 75 and is supported with its other end against the inner surface of the shifting claw around the same into their latched position.
