  • Locking anti-tip device
    Patent number: 5056877
    Abstract: A batching mechanism for an anti-tipping drawer mechanism rigidly attaches adjacent stacked drawers in the retracted position, thus mitigating the tendency to looseness in the mechanism. Preliminary withdrawal movement of any one drawer detaches the latching means and thereafter, further movement of the drawer actuates anti-tipping latching of the other drawers.
