Abstract
A turntable for turning vehicles, including a base member adapted to be supported on a flat floor and having a platform rotatably disposed above the base member for supporting a vehicle thereon. Rollers are utilized to reduce friction and support the platform as it rolls around and the rollers roll along the floor. The roller mechanism and actuating mechanism are extremely compact in order to allow the turntable to be low enough to the floor so that ramps are not needed to get a vehicle thereon and tipping is not required. A rod is pivotally attached to the underside of the platform and has a cog operatively attached thereto with a free end thereon for engaging a first or second cog holding mechanism attached to each side respectively of the base member. A cog is engageable with the cog holding mechanism to hold the platform in place, but the cog is movable on a selective basis in order to allow the platform to rotate 180 degrees, whereupon the other cog holding mechanism will automatically engage the cog and hold the platform steady. Shock absorbing structures are provided for preventing damage to the cog when it engages the cog holding mechanisms.
