Claim 1
Independent Claim
153 words
A runner for drawer support units comprising an integral channel section body member, one limb of which terminates in a tongue co-extensive with the said one limb, the said tongue and the base of the channel member being spaced apart and defining a blind slot, the said base of the channel section member having at each end an integral upstanding cranked arm of an L-configuration one part of the arm in connection with the base being horizontal and defining a fulcrum for the arm when the other part is inserted horizontally into a slot defined by an upright drawer support, whereby when the runner is rotated about the said fulcrum the runner rotates and the other part lockingly engages the body of the said upright to support the runner, and the tongue can be bent upwardly or downwardly out of the plane of the said one limb thereby locking the runner in position.
