ABSTRACT:
For self-closing a sliding door, e.g. of a showcase, combinations of belts and sprockets, cables and pulleys, rods and springs and the like, which have proved difficult to construct, service and replace are replaced by one or more constant force springs associated with a spring-retention cavity or other spring retainer. This permits the doors to be easily removed for servicing and for improved access to the interior of the showcase. Upon door removal, no self-closing apparatus still links the door to the case. The parts are simple and easy to replace, few moving parts are involved and the system is applicable both for new construction and for retrofitting to existing cases.
