Abstract: The said industrial design consists of the shape, configuration and ornamentation of an electric drill which is generally symmetrical about a central vertical plane extending the length of the electric drill; the electric drill has a battery portion, a driver portion and a grip portion extending between the top surface of the battery portion and lower surface of the driver portion; the grip portion has a trigger extending forwardly therefrom adjacent the lower surface of the driver portion;a central groove extends the height of each of the side surfaces of the grip portion, the central groove having an upper and a lower straight section which follows the profile of the grip portion and a forwardly inclined intermediate section which extends between the upper and lower straight sections thereof; the upper and of the upper straight section bends through an s-shaped section and then extends rearwards to the lower surface of the driver portion; the lower end of the lower straight section curves forwards through a short straight section; then downwards through another short straight section and then rearwards through a further straight generally horizontal section situated adjacent the upper surface of the battery portion; the grip portion curves inwardly away from the upper, intermediate and lower sections of the central groove to the rear of the grip portion, a series of generally parallel closely spaced-apart grooves extends rearwards from adjacent the upper section of the central groove towards the rear of the grip portion;the driver portion has a central section and five aligned projections extending forwardly from the front end thereof; the first projection is a short generally cylindrical section followed by a second generally conical projection having alternate wide generally rectangular shallow grooves with smooth bottom surfaces equally spaced between narrower generally rectangular shallow grooves with bevelled rear surfaces;the second generally conical projection merges into a third generally cylindrical projection having closely and equally spaced-apart generally identical grooves which extend from the front edge of the third projection along most of the length thereof; each groove having parallel sides, a curved bottom surface and a rounded end; the third projection merges into a fourth projection having a generally cylindrical rear portion and a truncated conical forward portion, the generally cylindrical rear portion having a series of equally spaced- apart generally identical grooves which extend the length of the rear portion, each groove having parallel sides, a curved bottom surface and rounded front and rear ends; the fifth aligned projection has a truncated conical shape the base of which merges into the truncated conical forward portion of the fourth projection;the central section of the driver portion has generally identical first longitudinal projections extending along the sides thereof, each first longitudinal projection having a generally flat upper surface and bevelled front, rear and side surfaces; the flat upper surface of each first longitudinalProjection has a shallow rectangular depression and the bevelled rear surface of each longitudinal projection has a series of laterally extending generally identical spaced-apart slots each having slightly convex sides and rounded ends;the forward portion of the central section of the driver portion has a generally curved upper surface which has a central generally rectangular shallow depression with rounded corners and an actuating switch situated therein; a pair of spaced-apart generally horizontally extending peaked sections with rear bevelled surfaces are symmetrically situated on either side of the central generally rectangular shallow depression; the rear portion of the central section of the driver portion has a flat trapezoidal upper surface with forward-facing U-shaped wedge-like projections situated on either side thereof which curve around the ends of the first longitudinal projections, each forward-facing U-shaped wedge-like projection has a flat upper surface and a flat side surface which merges into the flat trapezoidal upper surface;the rear portion of the central section has opposed upper and lower flat surface sections and a pair of opposed flat side surface sections, all four flat surface sections taper rearwards and inwards toward a slightly recessed flat rear surface having bevelled side surfaces and rounded corners; the upper and lower flat surface sections have side edges which taper inwards;the battery portion has a bottom surface, a generally flat top surface which merges into a smooth curved front end and generally identical side surfaces which merge through smooth curved corners into a rear surface of the battery portion; a flat horizontal area extends centrally along the side surfaces and across the rear surface of the battery portion, there being peaked raised areas on each side of the flat horizontal area; the front end of the flat horizontal area merges into a wedge-shaped raised section which has a rear-facing U-shaped area with bevelled sides encircling each wedge-shaped raised section; the upper side surfaces of the battery portion have narrow rear-facing elongated generally U-shaped projections each with a pointed forward end, the narrow rear-facing elongated U-shaped projections being situated adjacent the top surface of the battery portion;the bottom surface of the battery portion has a curved front edge and generally parallel side edges which merge through rounded corners to a rear edge thereof; the bottom surface has a central slightly recessed area which follows the profile of the bottom surface of the battery portion and has a series of shallow raised projections therein with flat upper surfaces.Representations of the design are shown in the figures wherein:Fig. 1 is a right side perspective view from the rear and above of the design of the electric drill;Fig. 2 is a right side elevation view thereof;Fig. 3 is a left side elevation view thereof;Fig. 4 is a top plan view thereof;Fig. 5 is a bottom plan view thereof;Fig. 6 is a front elevation view thereof;Fig. 7 is a rear elevation view thereof.Diagrams of the design are included.
