The present invention relates to a novel 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.
Temporarily holding a door in an open position is o~ten necessary for convenience and safety. One commonly employed method uses an overhead door control device that includes a pivoting arm attached between an upper portion o~ a door jamb and an upper part of a door. When the door is to be held open at an angle that does not exceed about 110 degrees, an overhead door control device is e~icient, e~ective, and convenient to install and m~intain.

DETAILED DESCRIPTION OF THE INVENTION
As illustrated in Figures 1 and 2, an overhead adju~table door holder assembly 10 has a channel assembly 22 posltioned 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. Positioned for sliding movement within the channel 23 is a slide as~emply 26.
The overhead adjustable door holder assembly 10 also $ncludes a jamb bracket 16 permanently affixed by screws, bolts, rivets, or other fasteners to a door jamb 14. A
~amb arm 18 is pivotally connected at one end to the jamb ;
bracket 16 and at its opposite end to the slide assembly 26. In pre~erred embodiments, the jamb bracket 16, jamb arm 18 and channel assembly 22 are ~ormed from brass or other durable, wear resistant material such as steel.

26 allows the slide assembly 26 to move along the channel 23 toward a spring support 24. When force is applied to open thc door, the slide assembly 26 moves along the channel toward the spring support 24 to engage the hold open assembly.
As best ~llustrated in Figures 3 and 4, the hold open assembly 36 includes a bracket 38 that is fixed to the channel a~sembly 22. A roller block 44, supporting a roller link 40 and rollers 42 movable in relation to the bracket 38, i8 attached to a movable rod 46 and its enveloping rod spring 48. 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 ad~u~t screw 56 that can move both vertically and a limlted horizontal distance.
In operation, the rollers 42 first engage ramp 28 of the ~lide assembly as t~le slide assembly advances toward the roller~ when the connected door is opened.
