  • Patent number: 9995069
    Abstract: An operator cab for a machine such as a motor grader includes an access door coupled to a frame by way of a hinge mechanism. The hinge mechanism has abutting cam and follower surfaces with geometry to control the swinging of the access door such as under the force of gravity. The cam surface has a double-sloped profile of rotation about the pivot axis of the hinge mechanism so that the access door swing is controlled in either of a first or a second swing direction toward a dwell location of the access door.
    Type: Grant

  • Patent number: 5520452
    Abstract: A file cabinet drawer slide assembly comprises a slide arm which is fitted with rotatable rollers, the rollers being dimensioned and configured to support a hem of a cabinet drawer. The slide arm is cooperable with a generally C-shaped track fixed to an inside side wall of the cabinet and configured to receive and support the slide arm in rolling telescoping relationship. A pivotable cam member is secured to the forward end of the slide arm in proximity to one of the rollers defining a slot through which the hem of the drawer travels. The bottom wall of the drawer is provided with a downward projection which engages a cross brace connected to the slide arm and normally prevents removal of the drawer. When the cam member is pivoted away from the hem, the drawer may be lifted sufficiently such that the projection disengages from the cross brace and the drawer can be removed from the cabinet.

  • Patent number: 5494175
    Abstract: A hanging file support structure for the drawer of a file cabinet comprises a hangrail and a bracket for supporting the hangrail in a generally horizontal position within the drawer. The bracket is generally C-shaped in cross-section and has pairs of hooks extended from edges thereof which are received in slots provided in a wall of the drawer. Two sets of slots are provided in the wall of the drawer such that the bracket may selectively be supported in either of two positions thereby defining two separate positions for the hangrail to accommodate hanging file folders of different widths.
