Abstract

An electrical charger equipped with a plug (7) for cableless insertion into a wall receptacle, with a power supply unit and a fixture for holding an electrical low-voltage appliance that is to be charged and has a storage unit for electrical energy, characterized in that the charger is equipped with at least one adapter (4a) for a power socket of the low-voltage appliance and/or with a mount containing a primary winding for the induction of a secondary winding in the low-voltage appliance that can be accommodated on the mount.

Claims

1. An electrical charger equipped with a plug (7) for cableless insertion into a wall receptacle, with a power supply unit and a fixture for holding an electrical low-voltage appliance (13) that is to be charged and has a storage unit for electrical energy, characterized in that the charger is equipped with at least one adapter (4a-4e;

24) for a power socket of the low-voltage appliance and/or with a mount containing a primary winding for the induction of a secondary winding in the low-voltage appliance that can be accommodated on the mount.

2. The charger according to claim 1, characterized in that it is equipped with a plurality of adapters (4a-4e;

24) secured to at least one carrier, in particular on a respective carrier plate (15, 28) for the sockets of various small appliances.

3. The charger according to claim 1, characterized in that the at least one carrier inside the charger is slidably and/or rotatably mounted on a shaft (25).

4. The charger according to claim 3, characterized in that the shaft (25) is essentially flush with the plugging direction of the receptacle in which the charger can be plugged.

5. The charger according to claim 3, characterized in that the shaft (25) can be fixed, in particular latched, securely in each position in which an adapter (24) can be connected with a low-voltage appliance (13) to be charged.

6. The charger according to claim 3, characterized in that a switch (23) can be actuated to bring an adapter (24) for a socket of a low-voltage appliance to be charged into a position in which the latter can be secured in the fixture, brought into electrical contact with the matching adapter (24), and charged.

7. The charger according to claim 6, characterized in that the switch is a rotary switch, a drive motor-actuated switch or a sensor-equipped switch.

8. The charger according to claim 6, characterized in that the switch is a pressure switch (23), with which the shaft (25) and an adapter carrier (28A) accommodated thereupon can be moved further from one rotational setting to the next during each actuation based on the principle of a ball-point pen.

9. The charger according to claim 1, characterized in that the name of the low-voltage appliance (13) belonging to the adapter (24) and/or the manufacturer of the low-voltage appliance (13) and/or a designation to be specified by the user can be shown on a front display panel.

10. The charger according to claim 6, characterized in that the switch (23), display, position of the adapter and/or another element of the charger is equipped with a lamp.

11. The charger according to claim 1, characterized in that it encompasses a basic body or a casing (1, 20) that holds the power supply unit, and mounts (5, 22) for holding the low-voltage appliance in the charging position.

12. The charger according to claim 11, characterized in that the mounts consist of a front mount and side mounts (5, 22).

13. The charger according to claim 11, characterized in that at least one of the mounts (5, 22) can be shifted and/or spring-loaded relative to the basic body (1, 20).

14. The charger according to claim 13, characterized in that the lateral mounts are designed as resilient projections for holding the small appliance from above.

15. The charger according to claim 14, characterized in that the lateral mounts (5, 22) of the charger are mounted so that they can rotate, and be twisted out of their resting position against the restorative force of a tension spring (29, 30).

16. The charger according to claim 1, characterized in that it is equipped with an optical and/or acoustic display means (18) for displaying the charge state of the small appliance.

17. The charger according to claim 3, characterized in that the shaft (25) and/or adapter carrier (28A) with several sliding contacts for establishing an electrically conductive connection between the ground output and another output of the power supply unit with a specific voltage, and a ground contact of the adapter (4a-4e;

24) as well as another contact of the adapter (4a-4e;

24) to which the voltage is applied, just as to the other output of the power supply unit.

18. The charger according to claim 1, characterized in that exhibits an area for holding an image, in particular behind a protective pane, especially one made out of plexiglass or acrylic glass.

19. The charger according to claim 1, characterized in that it exhibits a lamp that can be activated in particular via a photoelectric lighting controller (17).

20. The charger according to claim 1, characterized in that it can have a plug for connection (33) to a cigarette lighter in a motor vehicle alternatively or additionally to the plug (7).
