Definitions

  • the present invention relates to cabinets having telescopic shelves and, more particularly, to such cabinets with a mechanism to prevent tipping when heavily loaded telescopic shelves are extended from within the cabinet.
  • Filing cabinets and the like often have telescopic shelves which are heavily loaded with equipment such as files or electronic devices and it has long been recognized that mechanisms may be needed to prevent tipping of such cabinets when the shelf, which may be in the form of a drawer, is extended or opened.
  • the present invention is aimed at overcoming this problem.
  • a cabinet having:
  • the leg or legs may be either hinged or telescopic and, if telescopic, may form a plinth housed, in the retracted position, in the base of the cabinet and movable out of the front of the base into the extended position.
  • one or more pivotable wings or flanges may be provided along a vertical front edge of the cabinet in a position to partially overlie the front of the shelf or shelves when they are retracted, the wing or flange being pivotable to an open position allowing extension of the telescopic shelf or shelves when the leg is extended.
  • pivoted wing or flange may be a bar vertically movable into engagement with the shelf or shelves to prevent their extension and operable by movement of the leg.
  • the hinged wing or flange, or the vertically movable bar or rod may be interconnected to the plinth in a number of different ways.
  • the leg may be in the form of a telescopic plinth, as mentioned above, the plinth having a sloping flange engaging a pin which is retractable from a position in which it prevents opening of the wing or flange or else prevents a disengaging movement of the alternative bar from each of the shelves, by forward movement of the plinth causing the pin, following the slope of the flange (downwardly from front to back of the plinth) so that when the plinth is fully extended the pin is withdrawn to a position which allows the wing or flange or the vertically moving bar to move, in turn to allow opening of the telescopic shelf or shelves.
  • an abutment possibly in the form of an additional flange, on the bottom of the wing or flange or the vertical bar, can be provided to block the movement of the pin engaged with the plinth.
  • the wing or flange may, of course, if desired, provide a door to the cabinet.
  • the interlock mechanism may be constructed so as to cause the plinth to be retracted as the hinged wing is closed over the front of the shelves.
  • the leg or legs may be hinged and the interlock mechanism may include a pivot pin (which might have cranked arms) which engages with the wing and the leg so as to cause them to be moved together.
  • a pivot pin which might have cranked arms
  • the interlock mechanism may alternatively include cranked arms which hold the wings closed until a telescopic leg has been extended to the safe position, at which point the cranked arm is free to allow rotation of the wing or flange.
  • a cable or chain actuated interlock mechanism may be provided, the cable or chain being routed around elements within the cabinet and connected between movable bars or front closing wings or flanges and the leg/plinth.
  • the cabinet may store electronic equipment, such as devices for use in the telecommunications industry.
  • the cabinet 1 shown in figures 1 to 5 may be a conventional filing cabinet or similar having telescopic shelves or drawers 2 arranged one above another at any height within the cabinet.
  • a pair of vertically pivoted or hinged wings or flanges 3 are provided at the open front of the cabinet, one on each side, the wings or flanges 3 being pivotally mounted by appropriate pivot pins 4 at the top and bottom.
  • An interlock mechanism in the form of a retractable pin 5 sliding through a hole 6 in the base 7 of the cabinet is located, so as to prevent each of the wings 3 from opening, by connection to a sloping flange or the like 8 (see figures 4 and 5) disposed on a telescopic leg 9 in the form of a plinth housed in the base 7 of the cabinet.
  • the slope on the flange 8 allows the pin 5 to retract to a lower position as seen in figure 5, in turn allowing the corresponding wing 3 to be opened and the shelf or shelves 2 to be extended.
  • each wing 3 a horizontal additional flange or similar (not shown) may be provided to cover the opening 6 through which the interlock pin 5 moves, thus preventing the plinth from being retracted until the wings 3 have been closed. Since the wings 3 cannot be closed while the shelves are extended this prevents the plinth 9 from being retracted while the shelves are extended.
  • Figure 6 shows a second example, diagrammatically, in which the plinth or leg 9, which is again telescopically extendable at the base 7 of the cabinet 1, has a side member 11 with a cutout 10.
  • the wings 3 each have a pivot rod 4 which includes a cranked portion 12.
  • the pivot pin 4 is fixed onto the wing 3 in such a position that the cranked element 12 is substantially aligned with the side member 11 of the plinth 9 when the wing is in the closed position and is thus prevented from being moved out of this position until the plinth 9 has been extended to the point when the cutout 10 comes to lie adjacent the cranked element 12 of the pivot pin 4, at which point it may be rotated and hence the wing 3 rotated with it.
  • the plinth 4 cannot be pushed back to the retracted position without causing closure of the wing 3 and hence requiring the shelves to be retracted first.
  • Figures 7 and 8 show a third example of cabinet in which a pair of pivoting legs 9 are provided in the base 7 of the cabinet, pivotable between closed positions within the base 7 (see figure 8) and an open position (see right hand half of figure 7) in which they extend forwardly of the cabinet.
  • the pivot pins 4 on which the legs 9 are pivotable also provide the lower pivots for the wings 3 and the pins 4 are fixed to both the legs 9 and wings 3 so that they open and close together.
  • leg movement is possible within the concept of the present invention.
