Definitions
- the invention relates to an arrangement for securing a key opening a lock against unauthorized access or vandalism according to the generic term of claim 1.
- the arrangement is used for locking devices of cash boxes in one Open to the public and arranged in various machines Cashier units, which have a special protection against unauthorized access and whole especially against vandalism. These are e.g. B. Safes from coin-operated machines.
- the invention has for its object to an arrangement of the type mentioned realize that on the one hand prevents unauthorized manipulation of the lock and on the other hand, allows the anti-tampering measures from responsible personnel can be fixed with little effort then actuating the lock using a key.
- the arrangement (see FIG. 1a) for securing the key opening of a lock 1 against unauthorized access or vandalism is the key opening with one cover cap 2 provided, which in extension of the key opening has a slot-shaped passage 3 for a lock key.
- the Key opening is not shown in the drawing.
- the slot-shaped passage 3 has at its end facing away from the lock 1 an open to the outside cylindrical first cavity 4 for receiving a positive Securing cylinder 5 of a fuse, while the lock 1 end facing a second cavity 6 open to the outside as a cage for Has locking spring 7, which are arranged in the cage in such a way that in a rotary Movement of the fuse around its own axis in the fuse across this axis Arranged locking pin 8 snaps into place.
- the second cavity 6 is possibly in The direction of the axis of the fuse is extended by one on the outside of the Lock 1 existing cavity 9, which then together with the second cavity 6th forms a cage 6; 9 for receiving the locking springs 7.
- the outer wall of the closure cap 2 is thin-walled, it is on its outer side facing away from the lock, preferably with a cast-on eye 10 provided which laterally at least a part of the cylindrical first cavity 4 surrounds, but also, depending on the thickness of the outer wall, the slot-shaped passage 3 and can possibly laterally surround part of the second cavity 6 (see FIG. 2a).
- two locking springs 7 are preferably arranged, the z. B. each in 3a and 3b have the shape shown.
- the locking springs 7 then each have a constant width B (see Fig. 3b) and in the top view the shape of each garbled number "eight".
- a first elliptical part of the "eight" points over the full width B of the locking spring 7 extending longitudinal slot, so that it is a two Tines 7a and 7b has a fork-like shape, which is used during assembly securing easily by one of the two protruding parts of the locking pin 8 is compressed (i.e. the distance between the two prongs 7a and 7b is slightly reduced by pressure) before the locking pin 8 engages.
- each of the two locking springs 7 in its two parallel vertical webs 6a and 6b, which are not necessarily arranged vertically must be, each of the two locking springs 7 is housed.
- the dimensions of the Crosspieces 6a and 6b are preferably such that one locking spring 7 each without a large one Loss of space fits into it.
- the two locking springs 7 are thus, for. B. in the opposite direction, parallel to each other and point symmetrical to the intersection of the axis of the fuse with a central plane of the two locking springs 7 running perpendicular to the axis arranged.
- the securing cylinder 5 points to it after assembly the fuse, the side facing the lock 1 in extension of its axis projecting pin 11 as a rotary shaft, the radius or the largest Rotation radius, if the pin 11 is not cylindrical, at most equal to half the width of the is slot-shaped passage 3 and on his, after the fuse assembly, in the Cage 6 or 6; 9 protruding part has the locking pin 8, which on both Pages above is arranged in a transverse bore of the pin 11.
- the Security cylinder 5 is on its, after installing the fuse, from the lock 1 facing outer side with a depression 12 open to the outside for receiving a form-fitting pin 13 (see Fig. 5b) of an assembly key.
- the depression 12 is not slit-shaped, but preferably cylindrical with a slight elliptical cross section to avoid securing with a coin can be unlocked.
- the assembly key (see Figures 5a and 5b) is preferably a spanner that has a pin 14, at one end of the pin 13 and at the other A transverse toggle handle 15 is arranged at the end. Edges one outwards open side 12a (see Fig. 4b) of the cylindrical depression 12 and edges of a Butt outside 13a of the pin 13 (see Fig. 5b) of the assembly key are for better engagement of the pin 13 in the cylindrical depression 12, but also for optical Deception, preferably provided with facets, which is not shown in the figures.
- the fuse is installed as follows (see Figures 1a, 1b and 1c):
- the pin 13 of the assembly key is in the depression 12 of the locking cylinder 5th inserted and then the fuse into the cavity 4 using the assembly key, the passage 3 and the cavity 6 or 6; 9 axially pushed in until the Security cylinder 5 completely fills the cavity 4.
- a light Turn the toggle handle 15 of the assembly wrench each elliptical-cylindrical Shape of the depression 12 of the locking cylinder 5 and the pin 13 of the Assembly wrench a positive connection that allows the locking pin 8 snap into place by turning the two locking springs 7 again, which locks the inserted and rotated fuse.
- a light Tilting the assembly key can then be removed while the locked fuse in their, e.g. B. remains rotated by 90 ° and as a backup is effective because it makes the key opening of the lock 1 inaccessible.
- the safety lock is unlocked and removed as follows: With the help of the pin 13 inserted into the depression 12 of the securing cylinder 5 Assembly key and the positive locking of the elliptical-cylindrical shape of the depression 12 and the pin 13 can be rotated by the assembly key of the Unscrew the locking pin 8 from its locking device formed by the locking springs 7 and then the fuse from the cavity 6 or 6; 9, the passage 3 and pull out the cavity 4 axially and thus remove the fuse, causing the Key opening of the lock 1 is freely accessible, so that the lock 1 in the usual way Can be operated and opened by means of a lock key.
