Self aligning mechanical pointer
摘要:
A self-aligning mechanical pointer (10), includes a frame (12) attached to the front of a vehicle (14). A guide wheel (16) rides on a road surface and is rotatably carried by a wheel holder (18). The wheel holder (18) is connected to a swing arm (20), which pivots on frame (12) at point (22). An adjustable linkage member (24) connects swing arm (20) to a second swing arm (26). A guide rod (28) provides a sight means for an operator to align the pointer (10) with an intended target.
