Abstract:
A basketball backstop control for moving a group of basketball backstops in synchronous movement from one predetermined position to a second predetermined position, each basketball backstop having a winch, the control comprising:a source of AC power;each winch having a reversible motor, each motor being connected with the source of power and one of the basketball backstops to be moved;a first plurality of basketball backstop selection switching mechanisms connected with the source of power for selectively indicating the winches to be actuated and the basketball backstops to be moved, there being one selection switching mechanism for each winch motor;a second plurality of basketball backstop positioning switching mechanisms interconnected with the selection switching mechansims for selectively operating the winch motors in opposite directions;a first set of electromagnetic actuating devices connected between the winch motors and the selection and positioning switching mechanisms and being responsive thereto, there being a one-to-one correspondence between each device and each of the selection switching mechanisms;a second set of electromagnetic actuating devices connected to the first set of electromagnetic actuating devices and the positioning switching mechanisms; anda reset switching mechanism connected with the source of power for deactuating the switching mechanisms and electromagnetic actuating devices and selectively disconnecting the source of power from the first set of electromagnetic actuating devices,whereby certain of the selection switching mechanisms are first actuated to indicate a group of basketball backstops to be moved together, and one of the positioning switching mechanisms is then actuated to move the desired group of basketball backstops in one direction in unison, the reset switching mechanism being employed to disable actuation of the selection and positioning switching mechanisms once the basketball backstops have been moved from the one predetermined position to the second predetermined position.
