The mark consists of a three-dimensional configuration of an elevator roller guide. The roller guide includes three main components: the base mounting bracket, the central hub and the pivot arms. Each pivot arm holds two wheels, mounted at the extreme and opposite ends of the arm. The two "side" pivot arms are identical, and consist of two parallel, generally diamond-shaped faces, connected in the middle by an elongated cylinder. Substantially oval holes at the center of each face of the pivot arm reveal the springs and some inner workings of the guide. The third pivot arm is disposed between the other two pivoting arms and is rotated approximately 90 degrees relative to the other arms. This "face" pivot arm consists of two parallel faces, each shaped in an angular, three-section, wide-spread U configuration. These two planes are attached to each other in two places near the angles of the U shape. All three pivot arms are attached at their middles to a central hub, which consists of a cylindrical section attached to four flat rectangular surfaces. The base includes a substantially planar platform and a generally oval main support section, reinforced with an angled rib extending from the bottom of the main support section. The top of the oval main support receives the hub's cylinder. A large generally oval hole is formed in the lower portion of the main support.
