The present subject matter generally relates to a field of turntables. More specifically, the present subject matter relates to a turntable for the rotation of motorcycles. Yet more specifically, the presently disclosed subject matter provides rotation device for assisting with safe and controlled directional movement and pivoting of stationary motorcycles.
It is known that turntables are generally used for rotation of automobiles, other vehicles and/or displays. The turntables provide a platform, which is flush with a surrounding surface or suspended above the ground and is circular with a pivot point at a center thereof. The platform couples to a rotational motor through gearing systems.
Several turntables have been disclosed in the past that help to rotate vehicles, heavy equipment or displays. One such example is disclosed in a United States published application No. 20190389436 entitled “Vehicle Turntable” (the “'436 Publication”). The '436 Publication discloses a vehicle turntable comprising a central hub communicatively coupled to a control unit for receiving control signals; a plurality of wedge-shaped panels radially coupled to the central hub so as to form a circular surface; a plurality of wheels coupled to a number of the plurality of panels; and at least one motor configured to drive a corresponding one of the plurality of wheels and to receive the control signals from the central hub. Embodiments also include a system comprising a first turntable hub configured to control operation of a first turntable; and a control unit communicatively coupled to the first turntable hub to provide control signals to the first turntable hub.
Another example is disclosed in a U.S. Pat. No. 5,086,704 entitled “Motor Vehicle Turntable” (the “'704 Patent”). The '704 Patent discloses an improved motor vehicle turntable that may be installed in any location, typically in front of a garage for the purpose of rotating a vehicle so as to enable it to leave the area in the opposite direction from which it entered the garage. The motor vehicle turntable has a circular vehicle receiving platform supported by a polygonal support frame. The receiving platform and support frame are received within a cylindrical pit so that the upper surface of the platform is level with the surrounding terrain into which the pit is formed. A chain drive frictionally engages the perimeter of the polygonal support frame to rotate the receiving platform when the chain is moved by means of a drive motor and sprocket arrangement. The drive motor and sprocket arrangement provide a spring biasing to the chain to frictionally engage the perimeter of the support frame under normal operating conditions, but which permits loosening of the chain to manually rotate the receiving platform and support frame if there is a power outage or equipment malfunction.
Another example is disclosed in a U.S. Pat. No. 4,716,837 entitled “Automobile Turntable” (the “'837 Patent”). The '837 Patent discloses a turntable for positioning a parked vehicle is disclosed herein having a revolving platform operably mounted on a portable base with driving mechanism interconnecting the base with the platform. Rollers movably support the platform on the base in combination with reinforced tracks. Wheel stops are incorporated into the top surface of the platform for releasably retaining the vehicle in a parked position during operation of the turntable and remote controls as well as manual controls are employed for starting and stopping the operation.
The above discussed turntables have several disadvantages. For example, the turntables are extremely heavy, require on-site construction and assembly, and are very expensive. As a result, they cannot be used in narrow driveways, automobile showrooms, garages or the like to change the direction of the vehicle.
Therefore, there is a need for an improved turntable that is relatively inexpensive and easily assembled, that is readily operated to change the direction of a vehicle when there is not adequate room to turn the vehicle as it is being operated.
It is an object of the present invention to provide a turntable that allows the direction of a vehicle to be changed easily and avoids the drawbacks of known turntables.
It is another object of the present invention to provide a turntable that can be used in narrow garages, automobile showrooms, factories, or the like, to change the direction of displays.
It is another object of the present invention to provide a motorized turntable, which may be assembled on site and installed in a driveway or garage for rotation of vehicles.
In order to overcome the limitations here stated, the present invention provides a turntable for the rotation of motorcycles and displays. The turntable includes base arc and centering segments and deck segments. The base arc and centering segments with roller assemblies and motor is firmly attached to the floor. Wedge-shaped deck segments receive a motorcycle. The turntable includes a center hub connecting the deck segments. Here, the center hub acts as a pivot point for rotating the turntable. The turntable includes C-Channel arms extending from the center plate and connecting the deck plates.
In accordance with the present invention, the center plate comprises a hexagonal section with milled/machined areas. The rotating arms connect to the hub in the machined areas. The turntable comprises gear segments connected to the arms via a spacer. The gear segment spacer provides a gap between the arms and the gear segment and ensures they do not come in contact during operation of the turntable.
The gear segment connects to a drive shaft via a worm gear. The turntable includes a motor connecting the drive shaft. A user operates the motor via controller or remote controller. The motor engages the drive shaft causing the worm gear to rotate, which in turn rotates the gear segment. Rotation of the gear segment causes the arms to rotate with support from the roller assemblies. Rotation of the arms rotates the center hub, which in turn rotates the deck segments with the vehicle.
When a user activates the remote control, the turntable rotates clockwise at a set speed.
In one advantageous feature of the present invention, the turntable provides a smooth operation with minimum noise. Further, the turntable mounts easily and is readily operated to change the direction of a motorcycle when there is not adequate room to turn the vehicle as it is being operated.
The turntable allows the motorcycle to be rotated from facing forward to 180 degrees from that position, thereby minimizing the likelihood of back-over and reversing accidents in garages, for example.
In yet another advantageous feature of the present invention, the turntable allows parking, displaying, rotating and maneuvering motorcycles or other large or heavy items.
