Abstract

A control unit 1 for the lock of a safe having a front housing part 4 and a rear h housing part 3. A controller 6 is integrated in the control unit 1 that, when a correct combination is entered in the keypad 5, moves a module through a motor 11 in the number of turns corresponding with this combination. The module has a transmission board 8 integrated in the housing 2 of the control unit 1 and a bolt 9 for actuating the safe'"'"'s lock.

Claims

1. Control unit (1) for the lock of a safe with a multipart housing (2) that has a front housing part (3) and a rear housing part (4), wherein a controller (6) is integrated in the control unit (1) that, when a correct combination is entered in the keypad (5), through a motor (11) rotates a module having a transmission board (8) arranged in the housing (2) of the control unit (1) and a bolt (9) for actuating the safe'"'"'s lock by the number of turns corresponding with this combination.

2. Control unit in accordance with claim 1, wherein release takes place through a control unit (9) that enables manual adjustment of the front housing part (4) with regard to the rear housing part (3) between a normal position and a function position, whereby in the last-mentioned position the front housing part (4) can be rotated against the rear housing part (3).

3. Control unit in accordance with claim 1, wherein the front housing part (4) pivots with regard to the rear housing part (3) in the direction of their joint longitudinal axis (7) between a normal position and a pulled out position.

4. Control unit in accordance with claim 1, wherein a handle (10) is integrated in the front part of the housing (4) through which the front housing part (4) can be moved between the normal position and the function position.

10. Control unit in accordance with claim 1, wherein both housing parts (3, 4) are designed to be removed.

11. Control unit in accordance with claim 10, wherein if the front and rear housing parts (3, 4) are removed the transmission board (8) serves to open the lock.

13. Control unit in accordance with claim 11, wherein the transmission board (8) has a gear rim (19) on its front side (20).

5. Control unit in accordance with claim 5, wherein the keypad (5) is integrated in the front housing part (4).

6. Control unit in accordance with claim 5, wherein the front housing part (4) and the transmission board (8) are non-positively connected to each other in the pulled out position of the front housing part (4).

7. Control unit in accordance with claim 6, wherein a gear wheel connection serves for the non-positive connection.

8. Control unit in accordance with claim 5, wherein a rim (13) extends in the axial direction of the transmission board (8) that shows the turns of the front housing part (4) in interplay with a sensor integrated in the control unit (1).

9. Control unit in accordance with claim 8, wherein the rim (13) has a large number of openings (14-16) that correspond to the coding of the control unit (1).

12. Control unit in accordance with claim 8, wherein the transmission board (8) is fitted with a scale (17) on its front side (20).
