Description

June 14, 1960 c. B. RISER swam; DOOR HANGER Filed Feb. 4, 1958 United States Patent 6 SLIDING DOOR HANGER Clarence.- B. Riser, Sterlingyllh, assignor to Lawrence.

The presentinvention relates to a. novel door hanger structure, and. more particularly; to; adjustable. hanger structure of .the-utype suitable for. mounting. sliding doors.

One object ofthe invention ispto. providea translatable door han er which providesforsupport-and vertical adjustment: of a sliding. doorv byi means of an, improved and highly simplified. construction which can be confined within a vertically'and homizontally compactspace located above a. sliding-door and containedsubstantially within the normal: thickness of asliding door while at the same time. beingreadily accessiblefor adjustmentby a tool extending upwardly closely alongsidea door: supported by the. hanger.

Another object of;the.:present invention is. to proyide a novel. hanger structure for (1001813116. the like of the above described: type which structure may be readily and economically" produced and easily-assembled with a door.

Qther objects and advantages of. the: present: invention will. become apparent fromthe followingdescription and the accompanying drawings 1 wherein:

Fig. l is a fragmentary elevational. view showing a sliding door installation utilizing hanger structures incorporating features of the present. invention;

Fig. 2 is an enlarged fragmentary. cross sectional view taken along line 2-2 in Fig. 1;

Fig. 3 ha fragmentary sectionalv view taken generally along line 3-3 in Fig. 2;

Fig. 4 is. a sectional view taken. generally along line 4-4 in Fig. 2; and

Fig. 5 is. an exploded perspective showing a hanger structure incorporating features of. the. present. invention.

Referring now more specifically to the drawings. wherein like parts are designated. by the same numerals throughout the various figures, an installation is shown in Fig. 1 wherein a sliding door. 10 is supported from an overhead track 12' by means of a pair ofhanger structures 14 which are made in accordance with the present invention. Aswill be understood, the door 10-is adapted to be moved to and from the closed position shown in Fig. l and an openposition withina door receiving pocket 16 formed in the wall structure 18 in a known manner. As indicated best in Figs. 2 and 3 the track 12 disposed within and secured to a suitable header member 20.

The hanger structure 14 comprises a carriage assembly 22 and a bracket assembly 24 which are adjustably interconnected with each other in the manner described fully below. The carriage assembly comprises an elongated generally vertically disposed plate-like body member 26 having

rollers

28 and 30 mounted adjacent its opposite ends by means of

stub shafts

32 and 34 respectively. As will be understood, these rollers are adapted to ride on an upwardly facing surface of the track member 12. A finger element 36 is welded or otherwise secured to the body member 26 for extending beneath the track member, which finger element terminates in an upwardly inclined portion 38 having a threaded aperture which 2.940.112 Patented June 14, 1960 receives a screw. 40. The screw. 40 -m;ay be: selectively adjusted to the position shownxbest in:Fig. 2 so as to preventthe carriage assembly from being yraised ciently to disengage the rollers from the track member. and to a retracted position which will permit-thecarriage; assembly to be applied or removed, fi'omj thetrack member. Another finger element or lug 42 is provided; which finger element 42 extends oppositely from the. finger. element '36 and in the embodiment shown is into; gral with-the body member 26. This finger element is provided with an upwardly inclined end'portion 44 which has an aperture-therethrough for the purpose described below.

"Ihefbracket assembly 24 comprises a bracket member 46; having 'an-upstanding-portion 48 and, alaterally extending portion- 50. A plurality of apertures 52, is provided-indie bracket portionSO so that the; bracket is adapted .to be secured to the upper margin of adoor or the like by means of a plurality of screws 54. A finger element or lug 56 is struckfrom an intermediate section'ofthe-upstanding bracket portion 48- and extends laterally therefrom and oppositely from the bracket po tion 50. The finger portion 56 provided with an outer upwardly inclined end section 58. The end section 58 is inclined in substantially the same, manner as, the end section 44 of the finger element 42.

In accordance with a featureof the present invention, the carriage and bracket assemblies areadjustably. inter connected by means including a screw member 69 having an enlarged head 62 underlying the, finger portionjfi anda threaded shank which extends. upward-1y aligned apertures in thefinger portion 5S;-a.nd.the finger portion 44. A nut element 64. overlies the finger por tion 44 and threadedly receives the screw.-shank. "1.s shown best in Figs. Zfand. 5; the nut elementf64 and thefinger portion 44 are provided with complementaryv rounded surfaces. restraining the nut member against rotation. A spring 66is mounted on the screw, shank and compressed. between. the finger. portions 44. and 58 so as normally to maintain the nutmeinb i in n a e; ment with the finger portion 44. It will be noted'that the fingerv portions 44, and 58 are inclined so. that the screw member is arranged in a manner which displaces the slotted head thereof from the, upper edge of the door and whichexposes the slottedhead sothat i t may be readily. engaged by means of a screw driver 68. or the like indicated, in broken lines in Fig. 2. In otherwords, the structure is such that the, longitudinal axi Of the screw member is aligned with the gap between the upper edge of the door and the adjacent wall of the member 20. With this structure it will be appreciated that the door may be readily either vertically raised or lowered merely by turning the screw member 60in the appropriate direction.

The. carriage and bracket assemblies are provided with cooperable guide means which retain them against lateral separation from each other and against relative tilting movement so that undue lateral or bending stresses are not imposed upon the screw member. More specifically, the carriage body member 26 is provided with a pair of vertically

elongated slots

68 and 70 through which pins 72 and 74- extend. These pins have reduced diameter end portions 76 and 78 which extend through suitable apertures in the upstanding portion 48 of the bracket and which end portions are upset so as to secure the pins to the bracket. The free ends of the pins are provided with

enlarged heads

80 and 82 which overlie the body member 26 for preventing lateral separation of the bodymember from the upstanding bracket portion. it will be noted that the body member 26 is provided with a central slot 84. This slot is adapted to accommodate the upper end of the screw member 60 rs n s especially when the screw is adjusted so as to raise the bracket with respect to the carriage assembly.

While the preferred embodiment oftthe present invention'has been shown and-described herein, it is obvious;
