Abstract
A file cabinet comprises a case mounted on four caster wheels for mobility. A stabilizing wheel is mounted on the underside of a lower drawer behind the front edge. When the drawer is open, the wheel engages the floor and supports the forward end portion of the lower drawer independently of the case. When the drawer is closed, the stabilizing wheel nests within a forwardly open slot in the bottom wall of the case and is automatically elevated out of engagement with the floor. In an alternate form, the stabilizing wheel provides floor support for the drawer in its closed position.
Claims4
A mobile file cabinet comprising:
- a case which is generally rectangular in horizontal cross-section;
- floor-engaging swivel caster means on the bottom of the case at four corners thereof;
- at least one drawer movable between an opened position and a closed position within a compartment in a lower portion of the case;
- drawer stabilizing wheel support means on the underside of the drawer immediately behind the front edge of the drawer and being rotatable about a fixed horizontal axis which is transverse to the direction of movement of the drawer;
- and
- means supporting the drawer in said case providing sufficient vertical play between the front edge of the drawer and the case to lower the stabilizing wheel support means to engage the floor in opened position and to lift the stabilizing wheel support means out of engagement with the floor in closed position;
- whereby when said drawer is in closed position, said cabinet can be moved in any direction on the swivel caster means to or from a work site without interference by the drawer stabilizing wheel support means, and whereby further, when the drawer is in opened position at a work site with the stabilizing wheel support means engaging on the floor, it will be stabilized against unintended sidewise movement and forward tilting movement.
