  • Publication number: 20090134378
    Abstract: A combination of a rail, an upright, and a slide connector for attaching the rail to the upright includes a first connector part including a mounting arm secured to an underside surface of the rail adjacent one end thereof and a tongue depending generally downwardly from the mounting arm, and a second connector part including a mounting base secured to a side surface of the upright and a generally planar engagement body extending laterally outwardly from the mounting base. The engagement body has a slot therein for receiving the tongue when the rail is translated along an engagement axis from a disengaged position in which the first and second parts are generally free to move relative to each other to an engaged position in which the first and second parts are substantially inhibited from moving relative to each other, thereby attaching the rail to the upright.

  • Publication number: 20070297854
    Abstract: A corner bracket apparatus for a slidable frame includes a body having first and second arm portions depending therefrom, the first and second arm portions being oriented generally orthogonally relative to each other and adapted for insertion into respective first and second hollow framing members of said slidable frame, the first arm defining an outboard side edge and an inboard side edge generally opposite the outboard side edge and an internal pocket positioned therebewteen. The corner bracket apparatus further includes a lifter member pivotably coupled to the body and generally received in the pocket, the lifter member having a contact portion adapted to bear against a runner along which said slidable frame is adapted to slide, the lifter member being pivotable between an advanced position in which the contact portion is proud of the outboard side edge of the first arm, and a retracted position in which the contact portion is generally shy of the outboard side edge of the first arm.
