ABSTRACT:
A cartridge for binding multi-page documents comprises a center member and a pair of side members pivotally connected to the center member. In the closed operative configuration, the side and center members cooperate to form a U-shaped channel for receiving the documents. Pins extending between and supported by the side members enter aligned holes in the documents for suspending them. The side members are provided with a lock for releasably locking the cartridge in the closed configuration. The lock comprises a first tab on one side member having an opening therein and a second tab on the other side member having a protrusion. The two tabs cooperate such that the second tab protrusion releaseably engages the first tab opening when the cartridge is in the closed configuration. The cartridge may be made with a T-shaped bar or a center hook suspension system. A frictional coupling retains one side member to the center member in the closed configuration even though the second side member remains in the open configuration and the tab lock is inoperative.
