Definitions

  • the present invention relates to a door closure mechanism. It is particularly applicable to door closure mechanisms for cubicle doors, especially cubicles which are prefabricated and assembled on site.
  • doors for cubicles do not have closure mechanisms, although this would be desirable, for aesthetic and other reasons.
  • Door closure mechanisms are in themselves very well known, however they tend either to be visible or to be located with in the fabric of the building, either above or below the door or in the adjacent wall.
  • a door closure mechanism for a cubicle comprising damping means, biasing means and a pivot arm, all arranged to be located within a fixed part relative to which fixed part the door is pivotally mounted, and in which: the damping means has its distal end fixed relative to the fixed part and its proximal and pivotally connected to one end of the pivot arm; the biasing means has its distal end fixed relative to the fixed part and its proximal end pivotally connected the other end of the pivot arm; and the pivot arm is pivotally mounted relative to the fixed part and is arranged to be rotationally fixed relative to the door; whereby pivotal movement of the door relative to the fixed part causes the pivot arm to rotate relative to the fixed part thereby simultaneously moving the respective proximal ends of the damping means and biasing means.
  • the invention extends to such a door closure mechanism in combination with the fixed part and the door.
  • the invention extends to a cubicle or series of cubicles incorporating one or more such combinations.
  • the damping means is an hydraulic piston/cylinder arrangement.
  • the biasing means is a helical spring.
  • the fixed part is a hollow cubicle headrail.
  • the damping means, the biasing means and the pivot arm are located on a rigid base which is itself fixed within the headrail.
  • the pivot arm is connected to the door by means of an eccentric or non-circular cross-section shaft which is located in respective correspondingly shaped openings in the pivot arm and in the door at its upper edge.
  • the shaft passes through a circular or other hole in the base, allowing the shaft to rotate relative to the base.
  • the hole is constituted by a bearing such as a journal bearing or a roller bearing.
  • the biasing means is arranged to urge the pivot arm to rotate and in turn the door to move in a desired direction. This may be towards a door closed or a door open (or even an intermediate) position. Thus, as the door is moved in the opposite direction, the effect of the biasing means is increased.
  • the damping means acts to damp the effect of the biasing means thus damping the fall velocity of the door and ensuring that the door does not slam.
  • the door is a laminated, composite, or glass door. It is preferably pivotally supported at the bottom by a bottom support bracket.
  • a bearing such as a brass roller bearing may be provided in the support bracket which may receive a pin extending from the lower part of the door.
  • a cubicle 11 is defined by a rear wall (not shown), two side panels, one of which is shown at 12, and a door 13.
  • the door 13 is suspended from a headrail 14, to which the panel 12 is also attached, and is pivotally supported by a bottom support bracket 15.
  • the panel 12 is supported by a foot (not shown).
  • Movement of the door 13 is controlled by a closure mechanism 21 located within the headrail 14 and shown in detail in Figures 2 and 3.
  • the mechanism 21 comprises an hydraulic damping piston/cylinder 22 with a piston rod 23, a helical tension spring 24, a pivot arm 25 and a solid base 26.
  • the distal end of the cylinder 22 is fixed to the base 26 eg. by means of bolts 27, while the distal end of the spring 24 is attached to the base 26 eg. by means of a pin 28 as shown in Figures 4 and 5.
  • the pivot arm 25 comprises a solid core 29 with upper and lower laterally extending tongues which thus define two later U-shaped cavities 31, 32.
  • a respective pin 33, 34 extends between the upper and lower tongues.
  • the proximal end of the spring 24 is hooked around the pin 33 while the pin 34 extends pivotally through the proximal end of the piston rod 23.
  • An eccentric shaft 35 passes through a corresponding eccentrically shaped opening in the pivot arm 25 and extends rotatably through a circular hole in a bearing 36 located in the base 26. The end of the shaft 35 then received in a corresponding eccentrically shaped bore (not shown) defined in a housing (not shown) in the top edge of the door 13.
  • the base 26 is screwed to the headrail 14 by means of tapped holes 37.
  • Figure 4 shows the mechanism in the at-rest, door-closed position, with the spring 24 exerting a tensile force on the pivot arm 25, tending to move it clockwise about the axis of the shaft 35.
  • the shaft 35 is rotated anti-clockwise taking with it the pivot arm 25 which rotates anti-clockwise relative to the base 26. This causes the piston rod 23 to retract into the cylinder 22 and causes the spring 24 to stretch.
