The ornamental design for a stungun, as shown and described.
FIG. 1 is a perspective view of a stun gun showing my new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a bottom plan view thereof;
FIG. 4 is a left side elevation view thereof;
FIG. 5 is a right side elevation view thereof;
FIG. 6 is a front elevation view thereof; and,
FIG. 7 is a rear elevation view.
The shade lines (which are straight solid lines) in the figures show surface contour, but not surface ornamentation. The broken lines represent environment and are for illustrative purposes only and form no part of the claimed design; The two triangular structures (which are aligned in a horizontal configuration to go across the center portion of the embodiment) as identified by broken lines and marked by shade lines shown in FIG. 2 are purely environmental and thus are not shown and omitted for brevity in FIG. 1. The stun gun of an embodiment of present invention is shown by solid lines, including solid vertical contour lines. In addition, stipplings are also used herein to shown surface contours and character. The left-side elevational view can be symmetrical and mirror image of the right side elevational view of the embodiment. In addition, additional markings or text such as for example, “POLICE”, “SECURITY” or a company logo can be engraved or embossed on any of the flat surfaces in FIGS. 1, 4, and 5.
