Battery charger having angled wall in battery receiving opening, and battery pack charging system and cordless power tool system including same
First Claim
1. A charger for charging a battery pack that is detachably attachable to a cordless power tool, the charger comprising:
- at least a first side wall that at least partially defines a battery pack receiving hole shaped to receive and accommodate the battery pack, anda charging output element adapted to supply charging power to the battery pack,wherein the battery pack receiving hole has a lateral cross sectional area that decreases downwardly in the vertical direction of the battery pack receiving hole such that gravity will cause the battery pack to be guided to a prescribed position within the battery pack receiving hole,the charging output element is positioned so as to be proximal to a corresponding charging power input element of the battery pack when the battery pack is disposed in the prescribed position,the battery pack receiving hole comprises a bottom part that is adapted to support a lowermost portion of the battery pack when the battery pack is disposed in the prescribed position, andat least one opening is defined in the bottom part at a location that is lower in the vertical direction than the charging output element.

Abstract
A charger (40; 240; 340) charges a battery pack (20) that is detachably attachable to a cordless power tool (12). The charger has at least a first side wall (44b) that at least partially defines a battery pack receiving hole (44; 244) shaped to receive and accommodate the battery pack. A charging output element (62; 362) supplies charging power to the battery pack. The battery pack receiving hole has a lateral cross sectional area that decreases downwardly in the vertical direction of the battery pack receiving hole such that gravity causes the battery pack to be guided to a prescribed position within the battery pack receiving hole. In addition, the charging output element is positioned so as to be proximal to a corresponding charging power input element of the battery pack when the battery pack is disposed in the prescribed position.

23. A charger for charging a battery pack that is detachably attachable to a cordless power tool, the charger comprising:
-
at least a first side wall that at least partially defines a battery pack receiving hole shaped to receive and accommodate the battery pack, a second side wall coupled to the first wall, a third side wall coupled to the first wall and facing the second side wall, and a charging output element adapted to supply charging power to the battery pack, wherein the battery pack receiving hole has a lateral cross sectional area that decreases downwardly in a vertical direction of the battery pack receiving hole such that gravity will cause the battery pack to be guided to a prescribed position within the battery pack receiving hole, the charging output element is positioned so as to be proximal to a corresponding charging power input element of the battery pack when the battery pack is disposed in the prescribed position, and both of the second and third side walls are inclined relative to the vertical direction by an angle of inclination such that the distance between the second and third inner walls decreases downwardly in the vertical direction. - View Dependent Claims (24)
