Abstract
A patch fitting coverplate or cap for a patch fitting that extends a pivot point centerline of the patch fitting. The patch fitting coverplate may be constructed as a retrofit cover to integrate a patch fitting of one standard pivot point centerline to a door pane of another standard pivot point centerline. A patch fitting assembly including the patch fitting coverplate and patch fitting may also include buffers to fill in the interior portion between the extended patch fitting coverplate and the patch fitting. The patch fitting may be tapered at an edge close to the pivot axis of the door pane for smooth actuation of the door pane.
Claims9
A patch fitting coverplate for a pre-existing patch fitting, the pre-existing patch fitting operatively couplable to a door pane and a pre-existing coverplate having leading edge spaced away from a spindle extending from the pre-existing patch fitting by a first distance, the patch fitting coverplate comprising:
- one or more buffers cooperating with the body, and
- a body constructed and arranged to cover an external portion of the pre-existing patch fitting, wherein the body comprises:
- a tapered edge tapered relative to a horizontal axis of the door pane when the door pane is coupled to the pre-existing patch fitting;
- and
- a leading edge extending from the tapered edge in a direction towards a midplane of the door pane when the door pane is coupled to the pre-existing patch fitting,
- wherein the leading edge of the body is configured to be spaced away from the spindle extending from the pre-existing patch fitting by a second distance, wherein the second distance is greater than the first distance, and
- wherein the body is operatively couplable to the pre-existing door patch through a friction fitting with the one or more buffers.
