Abstract
In the operation of construction machinery, it is often desirable to be able to utilize a variety of implements on a single machine. While it extremely important to be able to attach and detach these implement very quickly, many mechanisms suffer trade-offs in a variety of design parameters. The coupling device of the subject invention utilizes a locking arrangement that provides a positive coupling force upon initial engagement of the device and maintains the positive force throughout the entire operation of each work implement. All of the components in the coupling device are maintained in linear alignment with the mounting components of the machine linkage to reduce the magnitude of operational forces transmitted therebetween and to provide a device that is extremely compact and versatile in design.
