Abstract
A mechanism preventing opening more than one drawer at one time, the mechanism having one movable locking bar for each drawer, using gravity to move a bar into interfering, locking position when its associated drawer is opened, and using an inclined surface to raise the bar into non-locking position as the drawer is shut.
Claims7
Locking mechanism for a plurality of vertically oriented horizontally reciprocal members which comprises
- a first member of said members,
- a second member of said members,
- a first vertically limitedly reciprocable locking bar,
- a second vertically limitedly reciprocable locking bar,
- first camming means carried by said first member for cooperation with said first vertically limitedly reciprocable locking bar to provide first vertical movement of said first vertically limitedly reciprocable locking bar when said first member is moved away from said first vertically reciprocable locking bar,
- second camming means carried by said second member for cooperation with said second vertically limitedly reciprocable locking bar to provide second vertical movement of said second vertically limitedly reciprocable locking bar when said second member is moved away from said second vertically reciprocable locking bar,
- first latch means carried by said first member for cooperation with said first vertically limitedly reciprocable locking bar to prevent horizontal movement of said second member upon said first vertical movement, and
- second latch means carried by said second member for cooperation with said second vertically limitedly reciprocable locking bar to prevent horizontal movement of said second member upon said second vertical movement.
