7 Claims.

This invention relates to a door mounting for Y swingable overhead garage doors or the like and position against rattling or looseness, and for supporting the door in its elevating movements.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views.

Figure 1 is an interior, and broken elevational view of a garage door and mounting involving this invention.

Figure 2 is a fragmentary vertical sectional view through one side of the door frame showin features of the invention in elevation.

Figure 3 is a part sectional and part diagrammatic view of the door and mounting illustrating the operation thereof to overhead position.

Figure 4 is a diagrammatic view of the door and mounting illustrating the elevating movements of the door.

Figure 5 is an enlarged fragmentary sectional view taken substantially upon the line VV of Figure 1.

Figure 6 is an enlarged fragmentary sectional view taken upon the line VI--VI of Figure 1.

In the drawings, there is shown a door 1 which is adapted to close a doorway in a building such as a garage or the like and that is adapted to be elevated to overhead position as shown in Figure 3. Upon the interior side walls 2 of the door opening and not far above the bottom thereof are plates 3 which extend a short distance into the doorway. Latch plates 4 are secured to the door and these latch plates are provided with depending prongs 5 that take over the plates 3 when th door is in closed position to prevent the lower end from moving outwardly in such position.

The upper end of the door is provided with a roller 6 upon each side which is adapted for travelling in a channel shaped track '7, the flanges of which have approaching lips 7a to prevent the escape of the rollers. Each track 6 has a depending portion 71) (Figure 4) at its forward end into which the rollers are adapted to pass when the door is in its closed position and prevent undue lateral movement of the upper part of the door in its said closed position.

Means are provided for controlling the door in its elevating movements and for elevating the same and the illustrated form of this means will now be set forth: For controlling the swinging movements of the door a pair of hinge rods 8 connect the door with the side walls of the doorway. Each hinge rod 8 has a right angled hearing portion Sat at its lower end which is journalled in bearing lugs 9 and 10 on a plate 11 secured to the lower portion of the door adjacent the side thereof. The upper end of each hinge rod 8 has an outwardly directed journal portion 12 that is journalled in the double armed links 13 which are pivoted to flanged plates 15 attached to the side walls 2. Coil springs 16 are connected to the journal portions 12 and these springs are anchored to angle clips 17 attached to the side walls 2 below the links.

Above the plates 15 are brackets 18 which are attached to the interior side walls of the doorway. These brackets include flanges or portions 18a that incline so as to extend over portions of the door. Upon the inner and upper end of each flange, there is pivoted a lever or fulcrum member 19 carrying a roller 20 at its lower'end. To the power arm of each lever 19, there is connected a link 21 provided with a plurality of apertures for adjustably receiving a spring anchor bolt 22 to which the upper end of a coil spring 23 is anchored. The lower ends of the coil springs 23 are anchored to the lower journal portions of the rods 8. These springs serve to cause fulcrum members to tilt in response to the tilting movements of the door and form fulcrums therefor. When the door is tilted outwardly as shown in Figure 4 and when the door is closed, the said springs force the lever 19 against the door to force said door against the door jamb.

Weather strips 24 (Figure 6) are attached to the exterior margins of the door and overlap the posts 2. These weather strips 24 may extend from the bottom to a suitable point upwardly to about the bracket 18. Above the brackets 18, the side wall 2 or posts are reduced in width and a corresponding portion 25 is attached to the sides of the door so that the strips 24 can pass through the do rway when the upper part of the door is tilted inwardly and the door is moved to an overhead position. In other words, the doorway is wider above the point where the door tilts inwardly.

The door is provided with a handle 26 upon its exterior whereby it may be elevated and is provided with a strap 2'7 whereby it may be pulled downwardly from its overhead position.

To open the door from its closed position, the operator will grasp the handle 26 and elevate the door in a straight vertical plane until the latch rongs 5 pass above the plate 3 and the rollers 6 pass above the depending arms 7b of the guide tracks 7. At this point, the operator will pull the lower end of the door outwardly as shown in Figure 4, whereby the rollers 6 will travel rearwardly upon the tracks 7. As the door is tilted, it will fulcrum upon the rollers 20 as shown in Figures 3 and 4, and it is only necessary to give the door an outward pull and upward thrust when the coil springs aided by the momentum of the door will carry the same to overhead position as shown in Figure 3.

In its closed position, the springs 23 acting on the levers 19 will force the rollers 20 against the door and tend to push the upper portion outwardly and in tight engagement with the door posts or walls. Likewise, the downward pull of the springs 16 will tend to force the door downwardly through the hinge rods 8 and maintain the same tightly closed.

We are aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

We claim as our invention:

1. In a building having a tiltable and upwardly movable door, fulcrum members, means on said building for supporting said fulcrum members in the path of said door, said members having rollers for engaging said door, and yielding means connecting said door and fulcrum members for urging the latter against said door in its closed position and forming an intermediate support therefor when the same is partially tilted.

2. In a building having a tiltable and upwardly swingable door, hinge rods connecting said door and building, Yielding means for normally closed or partially tilted.

.urging said hinge rods downwardly, brackets upon said building, fulcrum members pivoted to said brackets and yielding means connecting said fulcrum members and door for urging the former against said door.

3. In a building having an opening, an overhead movable door for closing said opening, ringe rods connecting said door and building, a pair of levers pivoted to the inner side of said door frame and lying in the path of said door and yielding means connecting said levers and door for forcing said levers against said door in its closed position.

4. In a building having a tiltable and upwardly swingable door, levers pivotally supported upon the building and yielding means connecting said levers and door and effective for forcing said levers against said door when the same is in its closed position.

5. In a building having, a tiltable and upwardly swingable door, brackets upon the inner side of said building, members pivoted to said brackets and lying in the path of said door and yielding means connecting said members and door for forcing said members against the door when said door is in its closed position.

6. In a building having a tiltable and upwardly movable door, levers pivotally mounted upon the inner side of said building and lying in the path of said door and yielding means connecting said levers and door and effective for forcing said levers against said door when the same is 7. In a building having a tiltable and upwardly movable door, levers pivoted to the inner side of said building and lying in the path of said door, rollers upon said levers. and yielding means connecting said levers and door for forcing said rollers against said door when the same is closed or partially tilted.
