Abstract

The present invention relates to a battery charging unit comprising a housing having a current supply means provided therein for supplying current to an electrical or electronic apparatus located remote from the battery charging unit, coupling means provided on the housing for coupling the current supply means to a mains power supply, means for coupling the remote apparatus to the current supply means, comprising a cable, and a reel provided in the housing for storing the cable in the housing when the battery charging unit is not in use, and allowing the cable to be dispensed when required. This has the advantage that by having a device around which the cable remains wound during storage and from which the cable is simply unwound from the charging unit when it is required eliminates the unsightly and messy bunching of the cable which is a feature of known charging units.

Claims

1. A battery charging unit comprising a housing having a current supply means provided therein for supplying current to an electrical or electronic apparatus located remote from the battery charging unit, coupling means provided on the housing for coupling the current supply means to a mains power supply, means for coupling the remote apparatus to the current supply means, comprising a cable, and a reel provided in the housing for storing the cable in the housing when the battery charging unit is not in use, but allowing the cable to be dispensed when required, wherein said reel is mounted within the housing and is able to be disengaged with respect to the housing to enable the user to manually wind the cable around the reel.

2. A battery charging unit according to claim 1, wherein the reel includes a reel plate which defines part of the wall of the housing.

3. A battery charging unit according to claim 1, wherein the reel includes a reel plate which comprises an opening means by which user can grip the reel and pull it out of the housing when it is desired to wind or unwind the cable around the reel.

4. A battery charging unit according to claim 1, characterized in that the cable exits the housing through an aperture in the housing.

5. A battery charging unit according to claim 2, characterized in that the cable exits the housing through an aperture in the reel plate.

6. A battery charging unit according to claim 5, characterized in that the aperture allows the reel to be pushed into the housing when the cable is unwound.

7. A battery charging unit according to claim 1, characterized in that the reel comprises a spindle mounted in a spindle housing in which it can be telescopically moved and at the same time maintained in the central position with respect to the housing.

8. A battery charging unit according to claim 7, characterized in that the spindle and the spindle housing comprise corresponding stop means to stop further movement of the reel and a cammed detent means to resiliently retain the reel in the pulled out position.

9. A battery charging unit according to claim 8, characterized in that the detent means provide sufficient retaining force on the reel so that the user has his hands free to hold the housing with one hand and wind or unwind the cable around the reel with the other without inadvertently pushing the reel back in the casing and yet low enough that when the winding operation is complete the user may press the reel back in the housing with sufficient force to overcome the cammed detent means.

10. A battery charging unit according to claim 1, characterized in that part of said housing comprises a cover which is openable to provide access to the reel and closeable to cover the reel.

11. A battery charging unit according to claim 10, characterized in that said cover is releasably attachable to said housing.

12. A battery charging unit according to claim 10, characterized in that said cover is pivotally attached to said housing.

13. A battery charging unit according to claim 10, chlaracterised in that said cover is slidably attached to said housing.

14. A battery charging unit according to claim 10, characterized in that said cover is provided with releasable locking means to retain the cover in the closed position.

15. A battery charging unit according to claim 12, characterized in that said locking means comprise a press-release locking means.

16. A battery charging unit according to claim 1, characterized in that said battery charging unit also comprises means for mounting a battery within the housing such that current is supplied from the current supply means to the battery mounted therein, the battery mounting means being provided such that the battery is mounted at an orientation whereby the longitudinal axis of the battery is at an acute angle to the horizontal and vertical axes of the housing.

17. A battery charging unit according to claim 16, wherein the acute angle is approximately 45 degrees.

18. A battery charging unit according to claim 16, wherein the battery to be mounted within the housing is part of an electrical or electronic apparatus, the whole apparatus being receivable in the recess.
