Abstract
An indexing device having a container for holding a plurality of cards therein and a cover pivotally mounted to the container by means of a shaft. When the cover is opened by the force of a resilient spring, the card placed at a desired location is exposed. A damping mechanism is provided around the shaft of the device to prevent the cover from being suddenly swung open, which would otherwise be caused by the resilient force.
Claims7
An indexing device comprising:
- a container having an open face,
- a cover pivotally mounted on a shaft passing through side walls of both the container and the cover,
- the container cooperating with the cover to hold a plurality of cards stacked therebetween,
- a resilient member producing a resilient force tending to open the cover when it is unlocked and to expose a desired one of the cards, and
- damping means including a viscous medium around said shaft for providing viscous resistance to the resilient force produced by the resilient member.
