Technical Field

[0003] The utility model relates to a battery charger, and more particularly to a portable battery charger adapted to receive a plurality of power tool battery packs. Background Art

[0004] Workplaces can be very large, and workers often have to change locations and need to carry all of their equipment with them (e.g., chargers, tools, etc.). Therefore, it is desirable for work area chargers to be compact, lightweight, and have one or more handles that enable workers to transport the charger from one location to another.

[0005] Many workplaces can be in locations that are susceptible to harsh environments that can damage electrical devices. Chargers can be susceptible to damage from cold temperatures, rain, and splashes. It would be desirable to create a charger with active or passive environmental protection so that the charger can be used in a variety of locations.

[0006] Since battery packs are expensive and chargers are often left unattended, it would be desirable to have a locking assembly in place to lock the entire charger or an individual battery pack into the charging dock.

[0007] Some specific embodiments of the present invention take these three desired features into consideration and balance them. Since the improvement of safety and environmental protection often means the increase of weight and size, the present invention seeks one or more arrangements or forms of chargers to provide optimization of portability, environmental protection and safety.

[0077] A protrusion 90 is disposed on the housing 18 adjacent the padlock latch 80. The protrusion 90 is sized such that the distal end 84 of the cable 76 can be received (e.g., wrapped, snapped, etc.) around the protrusion 90. When the cover 56 is in the closed position, the protrusion 90 and the distal end 84 of the cable 76 are covered by the cover 56. When the cover 56 is in the closed position, the distal end 84 of the cable 76 is encased over the protrusion 90 such that the cable 76 cannot be unhooked or removed from the protrusion 90.

[0078] In use, the cable 76 is wrapped around a stable structure (e.g., a table, a pole) to secure the charger 10 to the structure (e.g., a Fig. 9 Once the cable 76 is wrapped around the object, the distal end 84 of the cable 76 is secured (e.g., snapped) to a protrusion 90 on the charger 10 ( Fig. 10ATo further secure the cable 76 to the charger 10, the cover 56 is moved to the closed position so that the cover 56 covers the protrusion 90 and the distal end 84 of the cable 76 ( Fig. 10B ). The cover 56 prevents the distal end 84 from disengaging from the protrusion 90. A padlock may be inserted into the padlock latch 80 to lock the cover 56 in the closed position. When the cover 56 is locked in the closed position, the battery pack 14 cannot be removed from the charger 10. If the charger 10 is tied to an object, the padlock ensures that the charger 10 cannot be removed from the object by securing the cable 76 to the charger 10.

[0079] The charger 10 may include a drop protection assembly 92 disposed on the housing 18. The drop protection assembly 92 may include a molded edge 96 surrounding the perimeter of the housing 18 and extending through the housing 18. The molded edge 96 may be made of a rubber material.
