Ergonomically designed, electrically energized hand drill having a housing, longitudinally aligned with a hand, wrist and forearm support

摘要

An electrically energized hand drill (10) that incorporates a hand, wrist and forearm support (50). The drill (10) is ergonomically designed, in combination with the support (50), to reduce incidents of repetitive- use injuries and cumulative-effect traumas. The drill design includes a housing (12) having on its rear side (12B) an upper and lower handle support (30, 32) that support a substantially vertical handle (34). The handle has a trigger switch (35) that when depressed by the middle finger, a battery power-pack housing (38), located above the upper handle support, supplies power to an internal electrical circuit (14) that distributes the power to operate the drill (10). Located on the housing's lower section rear side (12B) is the hand, wrist and forearm support (50). When the support (50) is placed in an extended, functional position, the support allows the wrist and forearm to be supported in substantial alignment with the longitudinal axis of the hand, which is in substantial alignment with the longitudinal axis of the drill bit ( 80).
