A hub assembly (10) for use in arranging muntins (22) across a window pane includes at least first and second covers (12, 14) which are snap-fit and frictionally held together and which define at least one arcuate track (70) that is adapted to slidably receive carrier members (20) for interconnecting the muntins (22) to the hub assembly (10). The arcuate track (70) coacts with the carrier members (20) to retain the carrier members (20) in selective angular positions about the hub assembly (10). The hub assembly (10), which is semi-circular in plan view, can be selectively attached directly to a window frame, or to another similarly constructed hub assembly (10) to form a circular overall hub assembly.

DETAILED DESCRIPTION The present invention solves these and other deficiencies and problems in the art by providing an adjustable hub assembly for window muntins which accommodates a varying number of carrier members that can be shifted relative to one another.
More particularly, the hub assembly includes an arcuate, track defining portion which slidably receives the carrier members such that the number of carrier members utilized can be readily varied, as well as the relative angular positioning of the carrier members.
In a preferred form of the invention, the hub is formed by interconnecting two, identically constructed, semi-circular covers that are snap-fit together in order to define the arcuate track that is open at comer portions of the hub.
An inner rail associated with a respective one of the carrier members can be readily positioned within the track and guidably shifted along the track into a desired position.
A detent arrangement is preferably arranged between the track and the inner rail in order to index the carrier members in predetermined angular increments, such as five degree increments, along the track and to aid in retaining the carrier member in a desired position.
Each of the carrier members further includes a barbed section about which a respective muntin bar is to be placed.
The hub assembly can be utilized to cosmetically divide a semi-circular or even polygon-shaped window pane into various sections by centrally anchoring a straight side of the hub to a frame of the window, arranging a desired number of muntin carrier members about the arcuate portion of the hub and then positioning a corresponding number of muntins between the hub and the frame of the window.
The versatile hub assembly of the invention can also be used in dividing circular and polygon-shaped window panes by interconnecting the straight sides of two similarly constructed, muntin carrying hub assemblies such that a circular carrier track is formed.
In this case, the combined hub assembly would be located in the center of the circular window and the muntins would radiate outwardly therefrom
