  • a filing cabinet 10 is formed of a sheet metal cabinet having a front opening 12 and includes a plurality of conventionally mounted sliding file drawers or trays 14 which are movable outwardly of the cabinet for access thereto.
  • Each of the trays 14 is provided with a covering door 16, 18, 20, 22 and 24 which may be selectively moved to a closed position, illustrated by doors 16, 20,
  • the door 18 comprises a continuous sheet metal envelope including a front wall 26, a rear wall 28, and connecting top and bottom walls 30 and 32, respectively.
  • the continuous sheet of metal is bonded together at 34 by spot welding on the rear wall 28 to conceal the seam.
  • the front wall 26 of the door is substantially entirely planar except for an indicia means 36 at the upper right hand comer.
  • the rear wall 28 further includes a lateral depression 38 adjacent the bottom wall 32 for use as a handle.
  • a hat-shaped structural member 40 is bonded to the insides of front and rear walls 26, 28 and extends laterally of the door to rigidify the door.
  • the sheet metal envelope defines an opening 42 at each end, the openings receiving unitary plastic end caps 44 which are bonded therein.
  • Each of the plastic end caps 44 forms the door sliding guides and includes an elongated depression 46 for use as a handle, a stop tab 48 which will be later described, and a locking tab 50 which will be later described.
  • each of the end caps 44 includes a hole 52 which receives a pivot pin 54 formed integrally on a plastic guide member 56.
  • the plastic guide members 56 are attached to the ends of an elongated U-shaped trailer bar 58 so that the pins 54 and holes 52 pivotally mount the door 18 on the trailer bar 58.
  • the trailer bar guides 56 are received at either side of the cabinet within elongated guide channels 60 mounted on the cabinet. Their movement may be controlled by a cable control system, including trailer bar rollers 62, which forms no part of this invention and will not be further described.
  • the door may be swung from the vertical closed position, shown by door 20, about pins 54 up to a horizontal position shown by door 22, by grasping depressions 46. The door can then be pushed back within the cabinet, whereupon the end caps 44 enter the guide channels 60 and function as door guides. The door is then shoved all the way back into the cabinet to the fully retracted position, shown by door 18.
  • the tabs 48 have a dual function. In the door closed position, door in FIG. 3, the tabs 48 are gravity-biased into engagement with the edge of the cabinet to position the door in the closed position.
  • the shape and location of the structural member 40 within the door is such that the center of gravity C.G. of the door is located just outwardly of a plane extending vertically beneath the pivot 52, 54 of the door to provide the gravity bias to hold the door closed.
  • a door may be used as a posting shelf.
  • the reinforced door may be utilized as a posting shelf or writing surface, as shown by door 22 in FIGS. 1 and 3.
  • the indicia means 36 is retracted within the cabinet and only a planar surface is exposed.
  • the stop member 64 on trailer bar 58 engages a bent spring metal detent clip 70, riveted at '72 to the cabinet inner wall, to cause increased resistance to further movement of the door 22 within the cabinet. This provides a physical indication that the door has been moved to a position for use as a posting shelf.
  • stop member 64 Upon further movement of the door, stop member 64 will cam the clip 70 out of the path of travel and permit movement of the door to the fully retracted 7 position, as indicated by the door 18 in FIG. 3. Upon subsequent movement of the door outwardly, the stop member 64 strikes the back side of the clip 70 and cams it out of the way to permit the complete withdrawal of the door outside the cabinet for subsequent movement to the closed position, indicated by door 20 in FIG. 3.
  • the upper right hand corner of the cabinet mounts a lock cylinder 74 which is operable to reciprocate an elongated lock bar 76 which mounts at spaced intervals along its length locking pins 78.
  • the locking tab 50 of end cap 44 extends inwardly of the cabinet so that a recess 80 therein is located immediately above the lock pin 78.
  • the bar 76 is reciprocated upwardly so that the pin 78 enters the notch 80 to secure the door in its closed position.
  • end caps 44 have manifold functions. These unitary pieces include pivot holes 52 for pivoting the door to trailer bar 58, a finger grip depression 46, a dual purpose stop tab 48, and a locking tab 50, and also form an end closure for the sheet metal envelope and serve as guides for sliding the doors on channels 60.
  • the structure of the door is sufficiently rigid to enable additional use as a posting shelf.
  • the finger 64 and the detent clip 70 provide means for indicating that the door has attained a position sufficient to support itself for use as a posting shelf.
  • the construction of the door is such that the center of gravity lies outwardly of the door pivot to maintain a gravity biased engagement of the stop tab with the cabinet to maintain the door in closed position.
  • door construction of this invention provides many improvements in filing cabinet construction and features a reduced number of assembly parts, structural rigidity, and elimination of a separate posting shelf.
