| 1. In a drawer slide having first slide member and a second slide member, the first slide member being slidably extensible
from within the second slide member from a retracted position to an extended position in a cantilevered arrangement, the improvement
comprising:
a drawer mounting member;
a slot formed into the first slide member, said slot having an entrance section formed into an edge of the first slide member
for receiving said drawer mounting member into said slot, and a lock section for receiving said drawer mounting member from
said entrance section;
a rotary lock member having a main body portion, a follower portion and a rotary stop portion, said rotary lock member rotatably
mounted to said first slide member for rotating about an axis relative to main body portion between an open position and a
closed position, said follower portion facing outward of said main body portion, and said rotary stop portion disposed in
cooperative relation to said first slide member for locating said rotary lock member in said open position and said closed
position;
a biasing member engaging between the first slide member and said rotary lock member for urging said rotary lock member into
said closed position;
said main body portion and said follower portion adapted such that when said rotary lock member is disposed in said closed
position, said main body portion extends adjacent said drawer mounting member and prevents removal of said drawer mounting
member from said lock section of said slot, and said follower portion extends adjacent to said entrance section of said slot
disposed to engage said drawer mounting member when disposed in said entrance section of said slot, such that movement of
said drawer mounting member from said entrance section into said lock section of said slot rotates said rotary lock member
from said closed position to said open position, against said biasing member; and
said main body portion and said follower portion adapted such that when said rotary lock member is disposed in said open position,
said main body portion is moved aside of said drawer mounting member and said follower portion is aligned adjacent said slot
for passing said drawer lock member from said entrance section into said lock section of said slot, and said follower portion
extends aside of said drawer lock member when disposed in said lock section of said slot, such that said biasing member returns
said rotary lock member to said closed position with said main body portion disposed adjacent to said drawer mounting member;
wherein said rotary stop portion has a forward stop and a rearward stop which engages a forward edge of said first slide member
which is formed to define an edge profile having an open position stop and a rearward position stop engaged by respective
ones of said forward stop and said rearward stop portion of said rotary stop portion.
