ABSTRACT:
A play service center for toy self-propelled reversible drive vehicles that includes a lift ramp powered by the vehicle. Rollers carried by the lift ramp transfer power from the driven vehicle wheels through a pinion gear that engages a stationary curved rack gear to raise and lower the lift and vehicle. At the top of the curved rack gear a number of teeth are omitted and a stop is provided to retain the lift in the raised position. In order to lower the lift, the vehicle drive is reversed. Levered pads provide additional traction for driving the vehicle off the rollers and lift ramp. A power take-off drives service equipment such as a power meter as well as a rotating buffer or drill. The meter includes a biased dial pointer that provides an indication of the power transmitted by the vehicle wheels through the driven rollers.
