Adjustable wall mounted bracket

DETAILED DESCRIPTION The present invention relates to adjustable brackets and more particularly, to a wall mounted bracket assembly for adjustably supporting the trackway of vertical blind systems or the like.
The bracket assembly of the present invention is characterized by means formed as an integral part of a fixed bracket member, which permits a movable extension arm and trackway mounting spring clip to assume a stable and secure position at virtually any location between positions of maximum and minimum extension of the extension arm with respect to the fixed bracket member.
Such means includes a multi-functioning break-away tab which bridges one end of a through, extension arm adjustment slot provided in the bracket member and adds rigidity or rib strength to the bracket member in positions of the extension arm at or near the maximum limit of its range.
In the minimum position of extension of the extension arm with respect to the bracket member, the tab is simply broken away and discarded to prevent unsightly projection thereof forwardly beyond the trackway to be mounted.
In certain mid-range positions of extension, the tab is broken away and then employed as a shim or washer to span the distance between a plane defined by the mating or engaging surfaces of the bracket and the spring clip member and a parallel plane defined by the mating or engaging surfaces of the bracket member and the extension arm within the area of projection of the extension arm.
In this manner, the spring clip and thus the blind trackway mounted thereby remain at all times in planes parallel to the plane of the mating surfaces of the bracket member and the extension arm.
Any tendency of the trackway to cant or tilt is thereby effectively eliminated.
Essentially then, the present invention provides an adjustable bracket assembly for the trackway of vertical blinds, comprising a fixed bracket member containing an elongated, longitudinally extending slot closed at one end by an apertured break-away tab; an extension arm in the form of a plate having threaded mounting apertures and supported by the bracket member for sliding or adjusting movements relative thereto in a direction lengthwise of the slot; and an apertured spring clip for releasably securing a trackway in a selectively adjusted position, wherein the clip is fixed by a mounting screw to the extension arm in all positions of extension thereof with respect to the bracket member
