  • Locking feature for use in cartridge insertion guide applications
    Patent number: 7756442
    Abstract: A guide is used to protect a corona cartridge during shipping and during insertion into an electrostatic marking apparatus. The guide has dimensions that will permit the cartridge to fit therein and has a locking mechanism that securely holds the cartridge in place during shipment or movement. When the cartridge is to be removed from the guide and inserted into an electrostatic marking system, a handle attached to a latch is used to free the latch from a groove in the guide. The groove in the guide is located between two upwardly protruding ramps having a slidable side and a locking side that abuts the latch and holds it in place until activation when the latch handle frees it from the groove.
