Definitions

  • This invention relates to an overhead door holder assembly and, more particularly, to an overhead mounted door holder assembly having two pivotably connected arms that are lockable to hold open a door.
  • Temporarily holding a door in an open position is often necessary for convenience and safety.
  • One commonly employed method of holding open a door uses an overhead mounted door control device that includes a pivoting arm attached between an upper portion of a door jamb and an upper part of a door.
  • an overhead mounted door control device is efficient, effective, and convenient to install and maintain, is less subject to damage by vandalism or accidents, and does not present a potential stumbling hazard.
  • the door holder should be set to permit easy engagement of the door holder, hold the door against minor amounts of jostling contact without release, and yet still permit closing the door without undue effort.
  • an overhead mounted adjustable door holder assembly for attachment between a door jamb and a door, for selectively holding the door in an open position, comprising a jamb bracket for attachment to the door jamb; a double arm assembly pivotally attached to the jamb bracket, the double arm assembly having a first arm pivotally connected to a second arm and pivotally connected to the jamb bracket; and a channel assembly having a channel therein with a slide assembly positioned for movement in the channel in response to opening or closing of the door, the slide assembly being pivotally attached to the second arm of the double arm assembly; characterised in that a spring plunger assembly is supported by the double arm assembly, the spring plunger assembly having a plunger housing configured to retain a plunger replaceably connected to a plunger handle, and a lock plate engageable by the plunger to prevent pivoting movement of the first arm with respect to second arm, effectively holding, in use, the door in a user defined open position until a predetermined amount of force is applied to disengage the plunger from the
  • an overhead mounted adjustable door holder assembly for attachment between a door jamb and a door, comprising means for pivotally attaching a jamb arm to the door, the attaching means having first and second arms pivotally connected to each other; characterised by means for holding the door comprising a spring plunger assembly, the spring plunger assembly having a plunger housing containing a plunger replaceably connected to a plunger handle, and a lock plate engageable by the plunger to prevent pivoting movement of the first arm with respect to the second arm, thereby effectively to hold the door in a user defined open position until a predetermined amount of force is applied to disengage the plunger from the lock plate.
  • the invention also extends to a door incorporating a door holder assembly essentially as just defined.
  • an overhead mounted door holder assembly 10 has a channel assembly 22 positioned adjacent to the top of door 12.
  • the channel assembly 22 is attached to the door 12 so that its longitudinally extending generally U-shaped channel 23 is upwardly open.
  • a slide assembly 26 Positioned for longitudinal sliding movement within the channel 23 is a slide assembly 26.
  • the assembly 10 also includes a jamb bracket 16 fixed to a door jamb 14.
  • a double arm assembly 18 extends between the jamb bracket 16 and the channel assembly 22 to connect the door 12 and door jamb 14.
  • the double arm assembly 18 includes a first arm 20 and a second arm 21 connected to each other by a pivot 34, with the first arm also being pivotally connected to the jamb bracket 16 and the second arm being pivotally connected to the slide assembly 26.
  • a stop 42 is attached to first arm 20 and extends downward to engage and prevent pivoting of the first arm 20 across the second arm 21.
  • the jamb bracket 16, double arm assembly 18 and channel assembly 22 are formed from brass or other durable, wear resistant material such as steel.
  • the door can be releasably held in an open position by engaging a spring plunger assembly 28 attached to the second arm 21 below a lock plate 32 affixed to the first arm 20.
  • the spring plunger assembly 28 includes a plunger handle 30 threadably engaged with a plunger 36.
  • the plunger 36 is formed from hardened steel to increase its resistance to wear and is configured to have a bevelled edge 37 that enhances the ability of the plunger 36 to slide into and out of an aperture 33 defined in the lock plate 32.
  • the plunger 36 and plunger handle 30 are partially contained by a plunger housing 40 which is cylindrically configured to accommodate a plunger spring 38 which simultaneously engages the plunger 36 and the plunger housing 40 to bias the plunger 36 outward from the housing 40 to engage the lock plate 32 when the door is fully opened.
  • the plunger 36 can be extended from the housing 40 to enable, or retract to disable, the door holding feature.
  • the plunger handle 30 has a detent 48 that can be rotated with the plunger handle and once properly aligned can drop into a lock notch 44 that allows extension of the plunger 36 into its normal door hold open position. Continued rotation of the plunger handle through an angular distance of about 90 degrees pulls the plunger 36 up against the resistance of the spring 38, disabling the door hold feature, and allows the detent 48 to drop into a shallowly incised open notch 46. In this position, the plunger 36 will not engage the aperture 33 of the lock plate 32.
  • the door 12 can still be forced from a hold open position by exertion of sufficient force so the bevelled edge 37 of the plunger contacts the edge of the lock plate aperture 33 and acts as a ramp to ease sliding retraction of the plunger 36 into the housing 40 against the biasing force of the spring 38.
