Definitions

  • This invention relates to a cabinet of the kind suitable for storing files, stationery and the like.
  • a cabinet of the kind described may include a plurality of drawers arranged in a vertical array, one above the other.
  • the drawers may be large and, when filled with stationery, have a substantial mass. If more than one drawer is opened, at the same time, then there is a danger that the combined mass of the open drawers can be such that the cabinet is caused to overturn. This is a dangerous situation.
  • US 4,605,266 discloses such a cabinet.
  • the cabinet includes a plurality of drawers and a lock mechanism is employed which comprises an elongated lock bar and a plurality of locking tabs to act on the drawers.
  • the drawers can all be locked by means of the single locking bar, but it is still possible to open several drawers at the same time.
  • the invention is concerned with a cabinet which may contain a plurality of drawers which can be locked or unlocked in unison and which includes the safety feature that only one drawer can be opened at a time.
  • the invention provides a cabinet which includes a frame and a plurality of drawers which are separately slidable relatively to the frame between closed and open positions, a plurality of members which are respectively fixed to the drawers, at least one shaft which extends rotatably in the frame adjacent the drawers, and a plurality of catches, at least one for each drawer, which are movable together with the shaft, and which is characterised in that a plurality of biasing means fixed relatively to the frame, are respectively located adjacent the catches and in that the drawers, when all in the closed positions, are so positioned that the respective members act on the respective biasing members thereby permitting any drawer to be moved to an open position and, when any drawer is moved to an open position the respective biasing member causes rotational movement of its respective catch, and hence of the shaft and the remaining catches, so that the remaining catches engage with formations on the respective members thereby to prevent any of the remaining drawers from being opened.
  • Each drawer may include two of the catch mechanisms located respectively on opposing lateral sides of the drawer.
  • Each drawer when closed, may actuate or cause movement of the biasing means so that the catch can be moved between the first and second positions.
  • the plurality of the catches on the common shaft are rotatable in unison with the shaft and one another.
  • the biasing means acts on any one of the catches and causes it to move to the first position the shaft is simultaneously rotated and all of the catches are moved in unison to the first position.
  • this biasing means is moved out of engagement with its respective catch, by closure of the associated drawer, the common shaft and all of the catches may then be counter-rotated so that the catches are moved to the second position.
  • the first member may be made from any suitable material and preferably is a moulded plastics component.
  • the first member may include at least one sloping face, but preferably has first and second sloping faces which are engagable respectively with the biasing means and with the catch respectively.
  • the first and second sloping faces may be vertically spaced.
  • the biasing means may comprise a sheet of spring steel or the like which is fixed to the frame.
  • the catch may comprise any suitable component and may include a formation such as a projection which overlies the biasing means.
  • the first member may include a recess or other locking formation, on one side of the second sloping face, with which the catch is engagable or into which the catch is insertable.
  • all of the drawers may be locked simultaneously by causing rotation of the common shaft. This requires little physical effort. This may be accomplished by means of a key operated locking device or any similar component.
  • the locking device may be coupled to the common shaft by means of any suitable link. When all the drawers are locked no drawer can be retracted. If the shaft is rotated so that the catches are disengaged from the respective first members then each catch abuts its respective biasing means and deflects the biasing means. If any drawer is removed then the biasing means associated with that drawer deflects the associated catch and all of the catches are moved in unison to their respective locking positions.
  • FIG. 1 illustrates a cabinet 10, according to the invention, which includes a frame 12 and a number of drawers 14 which are mounted in any suitable way so that they are respectively individually slidable into or out of the frame.
  • the cabinet is shown schematically only for the construction of the cabinet frame, and of the drawers, is not important to an understanding of the invention.
  • Each drawer has associated with it, on opposed lateral sides, two catch mechanisms 16.
  • a lock 18, which is mounted at a suitable position on the cabinet 10, is connected via wire links 20 to steel shafts 22 and 24 which extend down opposed sides of the frame.
  • Figure 2 illustrates in enlarged detail a portion of the frame 12 and two of the catch mechanisms 16.
  • Each catch mechanism includes a flat spring steel member 26 which is fixed to the frame 12 by means of a screw 28, and a locking member 30 which is mounted to the associated shaft 24.
  • the locking members 30 are rotatable together with the shaft.
  • the locking member 30 has a projection 32 which overlies the spring steel member 26.
  • the shaft 24 passes through a number of spaced guides 34 along the height of the frame 12. At its upper end the shaft has a coil spring 36 which surrounds it. One end 38 of the spring is anchored in a hole in the frame 12 while an upper end 40 of the spring passes through a hole 42 in the shaft. The end 40 is connected to one of the wire links 20 which extend from the lock 18, shown in Figure 1.
  • Figure 3 illustrates a side wall 44 of a drawer 14. Fixed to the side wall, at a suitable location, is a moulded plastic member 46. This member is shown from the side in Figure 3 and in plan in Figure 5. The member includes a hole 48 through which passes a screw, not shown, whereby the member is fixed to the wall 44 of the drawer.
  • the member has a first sloping face 50 on one side and a second sloping face 52 on an opposed side.
  • the faces 50 and 52 are on a leading side of the member when referring to the direction in which the drawer is moved when it is moved to a closed position.
  • Visible in Figure 3 is a deep recess 54 to the right hand side of the second sloping face 52. It can also be seen that the first sloping face 50 terminates, at its upper end, in a raised formation or detent 56.
  • Figure 3 illustrates the drawer 14 in an open position i.e. in a position at which the member 46 is displaced from the spring 26 and the catch 30.
  • the catch 30 is movable from a position at which the projection 32 abuts the spring steel member 26 to a position 39, shown in dotted outline, at which the projection 32 is displaced well clear from the spring steel member 26.
  • the drawers can be all locked or, alternatively, the individual catches of the drawers are moved to positions, i.e. the solid line positions in Figure 3, at which any one drawer can be removed.
