INVENTOR ALBERT A. D|5HAW ATTORBEY.

3,057,005 Patented Oct. 9, 1962 3,057,005 SLIDING DOOR HANGER Albert Arthur Dishaw, 1433 Isabelle Ave., Mountain View, Calif. Filed Oct. 3, 1960, Ser. No. 60,153 3 Claims. (Cl. 16-105) This invention relates to building hardware and deals particularly with quick disconnect hangers for pocket sliding doors.

The pocket sliding door consists essentially of a regulation door panel connected to overhead rollers arranged to slide the door into and out of a wall pocket. There may be one or more of these doors which slides into the same pocket, or there may be one door for each pocket. In any case, the problem lies in the means for connecting the door to the rollers. It is known to those versed in the art of sliding doors, that the pocket into which the door slides is closely fitted to the door by stops, as is also the top of the door. It is also known that these doors must be adjusted to line up with the opening to make an effective closure for the opening.

The invention to be hereinafter described and claimed provides a hanger for doors of the above type which embodies a quick disconnect from the rollers in combination with a means for adjusting the door to the opening which may be used eflectively without removing any structural part of the opening including the stops.

Briefly stated, it is the primary object of this invention to provide a hanger of the character described which will permit a sliding door to be disconnected from the rollers by merely lifting the door and moving the door and the roller carriage relative to each other.

Another object is to provide a hanger for sliding doors wherein the vertical position of the door may be regulated without disturbing any finished parts of the opening. To accomplish this, I propose to put the means for turning the screw threaded bolt which supports the door in the roller carriage at the top of the door where it may be reached and operated through the space left between the door and the stop.

Other objects and advantages will become apparent as the description proceeds in conjunction with the drawing in which:

FIGURE 1 is a side view of my hanger as it would appear when supporting a door on a roller track;

FIGURE 2 is an end view of the same;

FIGURE 3 is atop perspective view showing my hanger mounted on the top of a door;

FIGURE 4 is a perspective view of the plate that goes on the top of a door;

FIGURE 5 is -a perspective view of the bolt with a flan ged slotted head that connects the door to the roller carriage;

FIGURE 6 is a perspective view of the spring member that goes beneath the bolt to hold it in place;

FIGURE 7 is a cross section substantially on the line 7-7 of FIGURE 3.

Referring to the drawing, and particularly to FIGURES 3, 4, 5, and 6, it will be seen that my invention comprises essentially three members, a base plate, generally desig nated P, shown in FIGURE 4, a threaded bolt B with a specially shaped head in FIGURE 5, and a spring member S, in FIGURE 6. These are shown assembled in FIGURE 3.

Taking up the members in the order stated, it will be noted that the base plate P is made from a strip of metal of suitable thickness and width and is adapted to be mounted on the top of a door through holes 11. The plate is bent upwardly in the central portion to hold one section 12 spaced above the top of the door, the end of which section is mounted flush with one edge of the door. In practice, there are two of these plates mounted on opposite edges of the door. The section 12 is made with a central hole 13 which is connected to the forward edge by a slotted opening 14 which is of less width than the diameter of the hole 13.

In combination with the above plate, I propose to use a specially formed bolt B to form a quick disconnect for locking the bolt in the plate. It will be observed that the bolt B has a screw threaded stem 15 which terminates at the lower end in an annular shoulder or hub 16 below which is attached a flanged head 17 having notches 18 on the periphery. In assembling the parts, the stem 15 passes through the slot 14 in the plate P and the annular shoulder 16 is pushed up into the hole 13 thereby locking the bolt in place. The means for holding the bolt up in place may take a variety of forms, but I prefer to use a thin flat spring member S shown in FIG- URE 6. This may he slipped under the lower side of the flanged head 17 on the bolt B and is so formed that it will normally exert an upward pressure on the bolt. It may be held in place by forming a slight upward extrusion 19 in the central portion which will fit into a small depression 20 on the bottom of the bolt B. The downwardly extending portion 21 on the spring S is adapted to come against th edge of the door and form a stop for the spring. It also provides for easy removal of the spring.

In mounting the hanger on doors, the plate P is secured to the top of a door D by screws 22 and the bolt B may be mounted in the plate at the time the plate is mounted, or, as preferred, the bolt B is mounted in a carriage C which carries rollers 23 that are supported on a track 24, the track in turn being supported on a structural member 25. The stem 15 of the bolt B passes through a screw threaded vertical hole in the central portion of the carriage C substantially as shown in FIGURES 1 and 2. From the foregoing, it is apparent that the load is carried on the bolt B and that B being detachably connected to the plate P the door may b disconnected from the carriage by merely raising front edge of the door D until the shoulder 16 drops below the hole 13 whereupon either the door or the carriage may be moved to pass the stem 15 through the slotted opening 14 and drop the door from the rollers. It is also obvious that the slotted flange 17 being at the lower end of the bolt B, the adjustments for height of the door may be made trom the bottom of the bolt thereby eliminating provision for allowing the bolt to pass into the top of the door. It will also be observed that the flangcd head 17 extends beyond the edges of the plate section 12 thereby presenting the notches so they may be reached and moved through slots 26 ordinarily left between the sides of the door B and conventional stops 27.

A quick disconnect of the above character, will not only provide means for quickly and easily adjusting sliding doors to fit openings, but will also provide means for quickly and easily removing the doors for inspection and repairs.

I claim:

1. A hanger for sliding doors comprising a plate adapted to be mounted on the top of a door, said plate having a section thereof spaced above the top of said door and substantially parallel thereto, there being a circular hole through the central part of said raised portion of said plate and a slot in said portion of less width than the diameter of said hole connecting said hole to the end of said raised portion with the slot running substantially parallel to the face of said door, a screw threaded bolt, the diameter of which will pass through said slot, said bolt having an annular hub on one end, the diameter of which fits within said hole, and a flanged head on the bolt below said hub having notches in the periphery thereof, said flange being of greater diameter than the width of said plate.

2. The device of claim 2 and in combination therewith a spring member adapted to be removably mounted between said flanged head and the top of said door for exerting a [force for maintaining said hub in said hole.

3. In combination with a roller carriage adapted to be supported on a track, said carriage having a vertical screw threaded hole in the central portion thereof, a screw threaded bolt adapted to be mounted in said hole, said bolt having a flanged head on the lower end thereof for turning the same, an annular hub on said bolt above said flanged head, a plate adapted to be mounted on the top of a door, said plate having a raised section for forming a space above the top of said door, said raised section having a hole in the central portion thereof adapted to receive said hub and a slot of less width than the diameter of said hole running parallel to the face of said door 4 adapted to pass the diameter of said bolt to allow said hub and said flanged head to pass between the top of the door and the raised portion of said plate to bring said hub into registration with said hole, and a spring between the top of the door and said flanged head to hold said hub in place in said hole.
