ADJUSTABLE DOOR HANGER Filed Aug. 19, 1963 United States Patent Ofiice 3,234,582 Patented Feb. 15, 1966 3,234,582 ADJUSTABLE DOOR HANGER Wayne C. Bates, Rockford, Ill., assiguor to National Lock Co., Rockford, 11]., a corporation of Delaware Filed Aug. 19, 1963, Ser. No. 302,905 1 Claim. (Cl. 16105) The present invention relates to a novel adjustable door hanger assembly for mounting and suspending a sliding door panel on a supporting track, including means for positively locking said hanger assembly to the door panel after accurate adjustment has been made.

In the assembly and mounting of a depending door panel whereby it is free to slide along an overhead track, each panel is generally suspended from two or more door hangers depending upon the size and weight of the suspended panel, there being generally one adjacent each upper corner of the panel. As it is difiicult to mount and maintain a depending sliding door panel in a vertical plane below the horiozntally arranged track with its vertical edges accurately aligned or plumb with the side or vertical door jambs, the supporting or hanging brackets are provided with some means for adjustably positioning the panel. However, in such prior adjusting means there is no provision for positively locking and thereby assuring retention of the hanger and door under all conditions of use.

The present invention comprehends a novel adjustable bracket for a door hanger assembly in which the bracket when once adjusted to position the door panel in its accurately aligned vertical hanging position, is positively locked and retained in such position.

It is an object of the present invention to provide a novel adjustable door hanger for mounting and maintaining a depending sliding door panel in its properly aligned poistion. Unlike prior hangers provided \m'th means for adjustment, the present novel hanger embodies locking means effective to positively and securely lock the door panel in accurately aligned position after suitable adjustment has been made.

In the present novel embodiment should the adjustment screw become loose, the door panel cannot sag for the hanger remains securely locked thereto in its previously aligned relation.

Further objects are to provide a construction of maximum simplicity, efiiciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

In the drawing:

FIGURE 1 is a perspective view of an adjustable sliding door hanger for supporting a sliding door panel upon an overhead track;

FIG. 2 is a view in end elevation of a pair of the adjustable sliding door hangers for slidably mounting adjacent door panels;

FIG. 3 is a view in front elevation of the novel adjustable sliding door hanger;

FIG. 4 is a view in end elevation of the sliding door hanger; and

FIG. 5 is an enlarged view in vertical cross section through the roller and its mounting for free rotation.

Referring more particularly to the detailed embodiment disclosed in the drawing, FIGS. 1 and 2 disclose a sliding door installation comprising an overhead track having spaced depending

rails

11 and 12 each provided with a trough or indented portion 13 receiving a roller 14 mounted for free rotation on a rivet or axle 15 (FIG. 5.) This roller is preferably of a plastic composition such as nylon and is rotatably mounted on the intermediate enlargement 16 on the rivet 15, the roller having an annular shoulder 17 abutting the head 18 of the rivet 15.

The other end 19 of the rivet 15 is reduced and projected through the upwardly projecting flange 20 on the upper end of a bracket 21 of the novel sliding door hanger 22, and this end 19 is then upset at 23 to anchor the rivet in the flange 21.

The novel sliding door hanger 22 comprises the bracket 21 having

plural otfset portions

24, 25 and 26. The upper offset and angularly arranged portion 24 includes the rearwardly offset flange 20 and spaced angularly arranged or

inclined portions

27 and 28 having a strengthening rib or embossment 29 therebetween. The intermediate oilset body portion 25 of the bracket is connected to the upper offset 24 by a horizontal portion or connecting ledge 31 closely conforming to and seating upon the top edge 32 of a sliding door panel 33. The lower depending oflset portion 26 of the bracket is spaced outwardly from the door panel to provide a thumb adjustment means for shifting the hanger about its pivot.

The body portion 25 of the bracket 23 is provided with a screw hole 34 for receiving a pivot screw 35, an arcuate slot 36 for receiving an adjusting screw 37, and a screw hole 38 for receiving a locking screw 39. The hole 34 is positioned at the center or axis of a circle containing the arcuate slot 36. This arrangement provides for positive angular adjustment of the bracket 21 of the adjustable sliding door hanger 22 about the pivot screw 35, and means or locking screw 39 for positive locking and retaining the hanger in such adjusted position and accurate vertical alignment of the door panel.

When the door panel is to be hung, it is placed beneath the track 10 and the roller 14 of each hanger 22 in its track rail. The hanger is then afiixed to the door panel 33 by inserting a pivot screw 35 in the hole 34 and inserting an adjusting screw 37 into the arcuate slot 36. With the door panel depending from its track, its bracket 22 is then swung to its adjusted position and the screws 35 and 37 tightened. To prevent future sagging of the door panel 33 when subjected to use and loosening of the adjusting screw 37, the locking screw 39 is inserted through the screw hole 38 of the bracket 21 and tightened, thereby assuring future positive retention of the door panel 33 in its properly aligned vertical position for sliding movement on the overhead track 10.

It is to be understood that one or more of these hangers may be employed depending on the size and weight of the door panels to be supported for sliding movement.

Having thus disclosed the invention, I claim:

An adjustable door hanger for slidably mounting and suspending a door panel in a horizontal track, comprising a bracket mounted on the upper edge of the door panel having a plurality of vertically oflset portions including an upper portion projecting above the upper edge of the door panel, inclined from a vertical plane and provided with an oflset end portion, an axle mounted on said offset end portion, a roller carried by and rotatably mounted on said axle and rotatable in the horizontal track, an intermediate flat body portion abutting and affixed to an inner vertical face of the door panel below the upper edge thereof and provided with a flat generally horizontal ledge connecting the intermediate and upper portions and adjustable upon the upper edge of the door panel, and a lower depending and relatively narrow portion ofiset away from said door panel to provide a thumb-actuated means for pivotally adjusting the bracket when assembled on the door panel, said intermediate body portion having a first opening adjacent one edge of the portion for receiving a screw pivotally mounting said bracket on the door panel directly above said lower depending portion, an arcuate slot generally horizontally spaced from said first opening receiving an adjusting screw whereby the bracket 3 4 is mounted for pivotal movement about the pivot screw, 1,070,243 8/1913 Frantz 16105 said first opening being positioned at the axis for said 2,627,633 2/1953 Shectman 16-105 arcuate slot, and a second opening generally vertically 3,011,209 12/1961 Majeske 16105 spaced from the first mentioned opening and arcuate slot 3,022,537 2/ 1962 Blackrner 16-105 receiving a screw for locking the adjusted bracket against 5 3,159,866 12/ 1964 Kellems 16105 further adjustment.
