Definitions

  • This invention relates generally to an overhead door holder assembly and more particularly to a stop block that is adjustably positionable to absorb force from a slide assembly connected to a door.
  • Conventional overhead door stops are not suited for use in conjunction with electronic door closers.
  • Such conventional overhead door stops commonly include one or more springs or other elastically compressible elements. These springs transiently engage a slide assembly that is pivotally connected to the door and moves in response to the door opening and closing. The engagement with the springs protects the door, the slide assembly and components of the overhead door holder assembly from damage caused by forceful or violent door opening.
  • conventional door stops do not merely absorb the force of a slide assembly. Instead, a substantial amount of the force is briefly stored by the spring and redirected against the slide assembly. This reverses the direction of movement of both the slide assembly and the connected door, causing the door to swing shut. Unfortunately, for many conventional electronic door closers, the door swings back past its stop point and the door is not properly engaged by the electronic door closer.
  • a 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, and a slide assembly within said channel pivotally attached to the jamb arm for movement in response to opening and closing of the door; characterised by a stop block assembly positioned in the channel for absorbing impact of the slide assembly as the door, in use, is opened.
  • the invention also extends to a door incorporating a door holder assembly essentially as just defined.
  • an overhead door assembly 10 has a channel assembly 22 positioned at a top 13 of a door 12.
  • the channel assembly 22 is attached to the door 12 by end caps 24 and 25 so that its longitudinally extending and generally U-shaped channel 23 is upwardly open.
  • the end caps are detachable from the channel assembly 22, and can be attached to a side of the door adjacent to the top of the door, in addition to the inset attachment illustrated in Figure 1.
  • the overhead door assembly 10 also includes a jamb bracket 16 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 is pivotally connected by pivot 19 to a slide assembly 26.
  • the jamb bracket 16, jamb arm 18 and channel assembly 22 are formed from extruded brass or other durable, wear resistant material such as steel.
  • the slide assembly 26 is positioned for longitudinal, back and forth, sliding movement within the channel 23.
  • a simple slide assembly that does not otherwise engage the channel assembly is illustrated, it will be appreciated that alternative slide assemblies having door hold open features may be used.
  • a friction controlled door holder, a slide assembly engageable with a hold open stop fixed to the channel assembly, or other mechanisms for engaging and holding a slide assembly in the channel assembly can be used to hold open a door.
  • a stop block assembly 28 for protecting the overhead door assembly 10 from damage caused by forceful or violent door opening is also positioned within the channel.
  • the stop block assembly 28 includes a shock absorbing stop block 29 that is constructed at least partially from steel or nylon filled thermoplastics. As best seen in Figures 3 and 4, the stop block 29 is shaped to define a threaded channel 41 through its centre that accommodates a threaded set screw 40. The stop block 29 additionally defines a cavity 43 into which a stop plate 42 can fit.
  • the stop plate 42 is typically constructed from steel or other durable, low wear material.
  • Fixing the position of the stop block assembly 28 simply requires setting the stop block assembly 28 in the channel 23 at a desired distance from the end cap 24.
  • the set screw 40 is rotated to advance it through the threaded channel 41 until it contacts the separate stop plate 42.
  • the stop block 29 is lifted (as seen in Figure 4) until it contacts inturned walls 47 of the channel assembly 22.
  • Continued advancement of the set screw simultaneously increases perpendicular force applied by the stop plate 42 against the channel assembly and stop block 29 against the inturned walls 47. Concomitant with the increasing perpendicular force is an increased static frictional force between the stop block assembly 28 and channel assembly 22 that holds their position fixed with respect to each other.
  • frictional force applied by a stop block assembly 128 is augmented by intermeshing engagement of serrations 144 on a stop plate 142 with matching serrations or grooves 146 defined in a channel assembly 122.
  • Fixing the stop block assembly 128 in position within a channel 123 is substantially similar to the embodiment previously discussed in connection with Figures 3 and 4.
  • a set screw 140 is advanced to lift the stop block 129 with respect to the bottom of the channel assembly 122. Continued advancement of the screw 140 locks the stop block 129 in position in the channel 123 by frictional engagement and mechanical coupling of serrations 144 and 146.
