Abstract:
1. A battery powered device comprising: a housing having a battery compartment apparatus disposed therein, the battery compartment apparatus configured to accept at least one battery; the battery compartment apparatus comprising a battery carrier and a locking hold down mechanism, the battery carrier being slidably mounted in the housing and the locking hold down mechanism configured to respond to insertion and withdrawal of the battery carrier into and out of the housing by locking the locking hold down mechanism against the at least one battery, thereby preventing undesired displacement of the at least one battery within the housing; wherein the housing is configured to alternatively receive a first size battery and a second size battery and the first and second batteries are different sizes and cannot be simultaneously contained within the housing; wherein the first size battery is tubularly shaped and has a first length and a first diameter and the second size battery is tubularly shaped and has a second length and a second diameter and the first diameter is smaller than the second diameter; wherein the locking hold down mechanism comprises a support frame and a retaining member secured to the support frame configured to contact and secure the battery within the battery carrier; wherein the support frame has a first end and a second end and the first end contacts the battery carrier and the second end pivots about an axis secured within the housing; wherein the battery carrier comprises a trough shaped tray having an inner surface, an outer surface, a first end and a second end and after withdrawal of the battery carrier from the housing, the first end remains inside the housing and the second end extends beyond the housing; wherein the trough shaped tray comprises a first pair of matching inclined surfaces and a second pair of matching inclined surfaces, the first pair of matching inclined surfaces are closer to the first end of the trough shaped tray and the second pair of matching inclined surfaces are closet to the second end of the trough shaped tray; wherein the second pair of matching inclined surfaces terminate at an end wall with an overhang extending therefrom; and the second pair of matching inclined surfaces, end walls and overhangs cooperate to define closed end slots.
