In PIg ₆ 1 a locking device designed as a lock with a housing 1 is shown _s at one end of which a flexible component 2 is attached, ZoB. a cable, a stranded wire, a wire, a rope, a chain, etc., preferably coated with plastic or enclosed by a tubular sheath or a sheath made of plastic, "At the other end of the flexible component 2 is a fixed cap 3 fixed made of metal, for example a cap made of sheet steel or similar material. The flexible component 2 can be of a length suitable for the respective application, for example 1.5 m. The section of the flexible component 2 provided with the cap 3 can be inserted into a bore or a through hole 4 that passes through the housing 1 "leads through" The flexible component 2 can be clamped in the locking device either on the cap part 3 or at another point along its length by rotating the end 5-1 5 in the locking roller.

The further structure and mode of operation of the locking device and in particular its locking and lock part is described with reference to FIGS. The drawing shows a cylindrical locking roller 6 which is disposed rotatably in the G-ehäuse 1, but on its rotation as shown in FIG. 2, is prevented in that projecting clamping plates in the locking roller 6 respectively with locking slots _e grooves 8 in the inner wall of the housing or Lock body 1 engaged, like Pig. 2 shows the locking slots 8 are provided separately from one another on the circumference at an angular distance of 90 ° when viewed in the direction of insertion of the key.Each locking plate 7 consists of a flat, essentially rectangular plate with a slot 9 through which the blade of the key 5 passes. Furthermore, the tumbler plates 7 are arranged in such a way that they are pressed against a stop by a spring, so that they move a predetermined length out of their guide

609829/0250

channel 10 protrude into a locking slot 8. Pin 11 engage in a hat in the key 5 to the To limit the direction in which the key is inserted «,

From the locking roller 6 is a thread provided pin 12 before which with a corresponding Internal thread in an axial bore of a clamping member 14 is engaged. The clamping member can freely in the bore 15 of the housing slide and is secured against rotation by two projections 16 with hats 17 in the wall of the housing 1 are engaged. The one with the pin 12 on the locking roller 6 in engagement with thread provided section ensures that the clamping member 14 slides along the bore 15 when the locking roller is rotated.

The end portion 18 of the flexible component 2 is attached to a cylindrical end cap 19 which is by a Bore in the end of the housing is passed before 'the locking device is assembled. This The section with the cap 19 has a widening that prevents the flexible component from loosening, as is the case with 3 "ig. and 3 show.

In the position of the locking device shown in Fig. 2, the bore 21 in the clamping member is aligned with the bore 22 in the housing and thus creates the through bore 4 according to J ¹ Ig ₀ 1 into which the free end of the flexible component, namely the Cap 3. When the correct key 5 is inserted, the tumbler plates 10 are withdrawn until they are substantially flush with the periphery of the locking roller, thereby releasing the locking roller 6 for rotation within the bore 15. After rotation of the locking roller 6, the bore 21 of the clamping member 14 is displaced with respect to the bore 22 of the housing, and it becomes clear that a flexible component which is initially inserted through the through bore 4

603829/0250

is clamped between the bore 21 of the clamping member 14 and the bore 22 through the housing 1. Will the key 5 is pulled out of the lock or from the locking roller, the tumbler plates 10 are released and come into engagement with a locking slot 8, so that the further rotation of the locking roller 6 is prevented and thus the clamped flexible component is locked in its position.

In I? Ig. 4 and 5 is a locking device shown according to another embodiment of the invention. The locking roller ^ is essentially correct corresponds to the locking roller described above, but has on its opposite to the key At the end of a projection 40.

Two arms 41 and 42 are mounted on a pivot axis 43 which in turn is attached to an inner wall 44 of the housing. The arms 41 and 42 are urged by a coil spring 45. At the end of the housing 141 two channels 46 and 47 with a semicircular cross section are provided, specifically at a point where they are ^{aligned with the bores 48 in the wall of the housing 1} T ′. Two flexible components 49 and 50 or also two sections of the same flexible component are located in the channels 46 and 47.

In the position shown, the arms 41 and 42 are in their clamping position, into which they are forced by the helical spring 45 «. The flexible component 50 at the front in FIG. 5 can be pulled through the channel 47 in the direction indicated by the arrow P without hindrance, but if it is pulled in the opposite direction, the associated arm 41 pivots about the pivot axis 43 until its lower, toothed one Edge enters the flexible component and thus prevents further movement of the flexible component (see I ¹ Ig ₀ 5)

609829/025 0

in the opposite direction, a key must be used inserted into the lock or the locking device and rotated the locking roller in such a way that that the projection 40 with the arms 41 and 42 in engagement comes and this brings out of engagement with the flexible components 49 and 50, against the effect of Helical spring 45 ο The locking roller is arranged in such a way that that the key can only be removed when the arms are in their clamped or locked position. The above description with regard to the component 50 located in front is analogous to the second Apply component 49, only reversing the directions.

In Fig. 6 is another embodiment of the locking device after üig «. 4 and 5 shown «here

140 a different arrangement of the locking roller is possible

the two cylindrical projections 60 and 61 instead of the j single projection 40 in Fig. ' 4 and 5 has »These projections 60 and 61 come into engagement with the ends of the arms 41 and 42 opposite the toothed portion engage and force them in the directions indicated by the arrows when the lock roller in the Unlocking position is rotated.

The locking device according to the invention can be used to hold several portable objects such as Cameras or portable radios to be interlocked to connect by the flexible component through a suitable Protrusion on each object is passed, e.g. by a handle, and then at its end inside the locking device or "the housing of this device is locked", such a way of using would be useful in preventing these items from being stolen
