The present invention is directed to improvements in the art of drawer suspensions, and particularly relates to an improved front release drawer suspension of the type employed for slidably supporting a drawer within a cabinet while permitting the drawer to be bodily removed when the same reaches an outwardmost limiting position relative to the cabinet. The drawer slide assembly includes a release member carried by the drawer, the release member being accessible from the front of the unit at the outermost limiting position of the drawer to facilitate removal of the drawer. The release assembly is characterized by means which positively deflect the forward motion limiting components into engagement as the slide components reach the outermost limiting position and preferably, in addition, permit reinsertion of the drawer without manual activation of the latching mechanism.
A front removable drawer slide assembly comprising, in combination, a drawer channel and a cabinet channel, said channels being elongate and generally U-shaped in transverse section, said channels each including a central web defining the branch of said U and a pair of spaced parallel track portions extending from the extremities of said branch and defining the legs of said U, said channels being disposed in vertically stacked parallel relation, with said webs being in lateral offset vertical planes and said branches extending in opposite directions, with the lower branch of the upper channel being in proximate spaced relation to the upper branch of the lower channel, an anti-friction roller mounted adjacent an extremity of each said channel, said rollers extending into the other said channels for slidably supporting said channels for translatory movement, a latch member movably mounted on one said channel, said latch member being shiftable between locking and unlocking positions, a stop member on the other said channel positioned to engage said latch member in the locking position thereof and limit separating movements of said channels, said latch member, in the unlocking position thereof, being disposed in the path of said roller of said other channel and being shifted to said locking position responsive to engagement with said roller.
