Definitions

  • This invention relates to an adjustable overhead door holder assembly and more particularly to an overhead door holder assembly having a low profile suitable for mounting in a door top inset, that can be easily adjusted without removal of a hold open stop.
  • An overhead 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 door control device is efficient, effective and convenient to install and maintain.
  • Overhead door control devices are less subject to damage by vandalism or accidents and do not present a potential stumbling hazard.
  • an overhead 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 jamb arm pivotally attached to the jamb bracket; a channel assembly having a channel therein defined by channel walls; a slide assembly positioned for movement in the channel, said slide assembly being pivotally attached to the jamb arm; and a hold open assembly attached to the channel assembly: characterised in that said hold open assembly has a roller link with connected rollers for engaging the slide assembly to hold the door in an open position, and a movable rod for modifying position of the roller link to allow for engagement/disengagement with the slide assembly and there being an adjustment assembly for varying force of a spring on the movable rod, the adjustment assembly having primary and secondary wedges positioned between the roller link and the movable rod.
  • an overhead adjustable door holder assembly for attachment between a door jamb and a door, comprising means for pivotally attaching a jamb arm to said door; a channel assembly for attachment to the door and having a channel defined therein; means positioned within the channel assembly for holding the door and comprising a slide assembly positioned for movement in the channel, the slide assembly being pivotally attached to the jamb arm and having slot defined therein, characterised by an adjustment assembly for varying force on rollers for engagement with the slot of the slide assembly, the adjustment assembly comprising a primary wedge movable with respect to a secondary wedge to adjust position of the rollers.
  • an overhead door holder assembly for attachment between a door jamb and a door, the assembly being configured to allow adjustment, in use, of horizontal distance between components by vertical adjustments of a wedge adjust screw
  • the assembly including a channel assembly attached to the door and having an upwardly opening channel defined therein, means positioned within the channel assembly for holding the door and comprising a slide assembly having slot defined therein, and an adjustment assembly, characterised in that said adjustment assembly is for varying force on rollers for engagement with the slot of the slide assembly, the adjustment assembly comprising a primary wedge connected to a wedge adjust screw, the primary wedge being configured for horizontal movement, in use, with respect to a secondary wedge through adjustment of the wedge adjust screw, the horizontal movement acting to vary the force on the rollers.
  • the invention also extends to a door incorporating a door holder assembly essentially as just defined.
  • an overhead adjustable door holder assembly 10 has a channel assembly 22 positioned in a door inset 20 at an upper edge 13 of a door 12.
  • the channel assembly 22 is attached to the door 12 so that its longitudinally extending and generally U-shaped channel 23 is upwardly open.
  • a slide assembly 26 Positioned for sliding movement within the channel 23 is a slide assembly 26.
  • the overhead adjustable door holder assembly 10 also includes a jamb bracket 16 permanently affixed by screws, bolts, rivets or other fasteners to a door jamb 14.
  • a jamb arm 18 is pivotally connected at one end to the jamb bracket 16 and at its opposite end to the slide assembly 26.
  • the jamb bracket 16, jamb arm 18 and channel assembly 22 are formed from brass or other durable, wear resistant material such as steel.
  • the slide assembly 26 When the door 12 is normally closed with its upper edge 13 positioned parallel to and adjacent to the door jamb 14, the slide assembly 26 is positioned in the channel 23 at its maximum distance from the spring support 24. As the door 12 is about fully opened, as shown in Figure 1, the pivoting connection of the jamb arm 18 between the jamb bracket 16 and the slide assembly 26 allows the slide assembly 26 to move along the channel 23 towards a spring support 24. When force is applied to open the door, the slide assembly 26 moves along the channel toward the spring support 24 to engage the hold open assembly.
  • the hold open assembly 36 includes a bracket 38 that is fixed to the channel assembly 22.
  • a roller block 44 supporting a roller link 40 and rollers 42 movable in relation to the bracket 38, is attached to a movable rod 46 and its enveloping rod spring 48.
  • an adjustment assembly Positioned between the rod spring 48 and the roller link 40 is an adjustment assembly that includes a primary wedge 52 and a secondary wedge 54.
  • the primary wedge 52 is connected to a wedge adjust screw 56 that can move both vertically and a limited horizontal distance.
  • the rollers 42 first engage ramp 28 of the slide assembly as the slide assembly advances toward the rollers when the connected door is opened.
  • the required force necessary to depress the rollers 42 provides positive feedback for imminent engagement of the slide assembly and the hold open assembly 36. Engagement of these elements to hold open the door is realised when the rollers 42 are forced into a slot 30 defined in the slide assembly 26.
  • the door remains in a held open position until substantial force is applied to the door to depress the rollers 42 to disengage the slide assembly 26 from the hold open assembly 36.
  • the exact force required to engage or disengage the slide assembly from the hold open assembly can be easily varied using the adjustment assembly 50.
  • the primary wedge 52 is connected to a wedge adjust screw 56 extending in a vertical orientation for easy access. Adjusting the screw 56 changes the spatial relationship between the primary and secondary wedge, increasing or decreasing a horizontal distance across the combined primary and secondary wedge and altering the length of the rod spring 48 and subsequent force transferred to the rollers 42. Instead of needing to readjust the position of the partially hidden and horizontally extending adjustment rod 50 directly, the vertical manipulation of the wedge adjust screw is converted into a horizontal movement of the wedges, which in turn modify the force necessary to engage or disengage from the rollers.
  • An additional aspect of the present construction is its capacity for absorption of door opening impact. As best illustrated in Figure 2, when the door is opened far enough, the slide assembly 26 impacts and is slowed by contact with springs 32 and 34 held by the spring support 24 to extend longitudinally in parallel spaced apart relationship along the channel 23. Both springs have substantially equal spring constants and resistance to compressive force. By slowly distributing the force of door opening, the springs prevent shock damage to the assembly 10.
