claims. (c1. zii-.19)

' 10 a doorway a door, which in its vertical position will close the doorway, and in its horizontal elevated position will projectr through the doorway to form an overhanglng canopy protection.

It is also an object to provide a swinging door 15 with means for supporting the door so that it may travel bodily as well as swing, the bodily movev ment being guided by guides.

It is a further object to provide a one-piece panel door with guides for receiving rollers located on the upper end of the door, said guides being provided with horizontal channels for guiding the upper end of the door horizontally, and with vertical downward extensions, whereby the door may be moved vertically downwardly as it reaches its closing position, the parts of the guides forming the downward extensions serving to hold the upper end of the door against the door jambs.

These and other objects andv advantages will appear from the following description taken in connection with the drawings.

Referring Ito the drawings:

Figure 1 is an inside elevation of one sideof the door and the door jamb to which the door is attached, the door and the jamb'shown broken away.4

, FigureZ is a section on the line 2--2 of Figure 1. In this figure the door is in its closed position.

Figure 3 is a view similar to Figure 2 but with Vthe door elevated, due to the inward opening movement. I

AFigure 4 is a view similar to Figures 2 and 3 but with the door in a position intermediate that shown in Figure. 3 and its open horizontalposition.

Figure 5 -is a section through the door showing it in its open position.

Figure 6 isa top plan view of the door and its operating mechanism, showing the adjacent wall structure in section.

Figure 7 isa section on the line 1-1 of Figure 1.

Figure 8 is a section on the line il--8` of Figure 1.

The door of this invention is adapted tobe used in connection with garages, storage-rooms and the like, in which there is'an opening or passageway provided on each side with a door jamb I, and across the top with a lintel 2. Beneath the lintel and extending toward the inside of the building is a strip 3 suitably attached to the lintel in any suitable manner. For the purpose of closing the passageway between the two door jambs a one-piece door 4 is provided.

Each door jamb has thereon an inwardly extending bracket 5 to which a link 6 is pivoted in- 10 vtermediate its ends. To one end of this link 6 one end of a lever I is suitably pivoted, while the other end of the lever 1 is pivotally attached to `a bracket 8 attached to the door below its middle point. To the other end of the link 6 is pivoted 15 a lever 9 intermediate its ends. One end of this lever 9 is pivotally connected tol one end of a link I I), which has its other end pivotally connected to the lever 1 intermediate its ends. The other end of the lever 9 is provided with a counterweight II.

When the.door is in its closed position it engages at each inside edge-with a plate or weather strip I 2, attached to the jambs of the door. These strips extend from the bottom of the doorway up- 25 ward to a point past the center line. Cooperating with the weather strips I2 are plates I3 attached to the door and adapted to engage the jambsV above the strips I2.

The door is provided at its upper end, at each 30 edge, with a bracket I4, on which there is mounted a roller I5. On the upper edge of the door is a strip I6, which is adapted to engage the insideedge of the lintel 2 and the top edge of the strip 3 when the door is in a closed position, as shown 35 in Figures 1 and 2. The rollers I5 are adapted to travel in horizontal guides I1 in the form of channel tracks. Each guide is supported at its inner end by means of a bracket I8, suitably attached to some part of the building. 'I'he ends 40 of the guides adjacent the doorway are supported by means of brackets I9. These brackets have horizontal passageways or horizontal channels 20, corresponding in shape to and in alignment with the channel parts of the trackways or guides Il,

`and downwardly extending channelways 2| into which the door rollers enter just before the door reaches its closed position.

In the final closing of the door thedoor moves. downwardly, with the rollers in the downwardly 50 extending channelways 2| so that when the door is closed the brackets I9 serve to prevent the inward movement of the upper end of the door. The lowerl end of the door is held against inward movement by means of the plates I2. The door 55 is prevented from moving outwardly by means of the plates I3 engaging the jambs, and by means of the rollers I5 engaging the lower parts of the brackets E9.

Operation When it is desired to open the door it is first moved upwardly from the position shown in Figure 2 to that shown in Figure 3. During this part of the operation of the door the rollers move upwardly in the channelways 2l until the rollers reach a position for movement in the channels of the guides il. This upward movement of the door is aided by the counterweight it, which acts in a plane parallel to the door for raising the door.

During this upward movement of the door the link 6 serves as a lever, the counterweight acting on one end of the lever to move the door connected to the other end of the lever. The initial upward movement may be brought about by applying downward pressure to the counterweight or by lifting the door. When the door gets in the position shown in Figure 3 a movement of the counterweight to the right or a movement of thek lower end of the door to the left causes the whole door mechanism and its operating lever system to move about the pivot of the link G. In this movement the rollers travel along the guides il.

Figure 4 shows the door in what might be called the second stage of its opening movement. A continued movement of the counterweight to the right and downward, with the lower end of the door moving to the left and upward will bring the door to its open position, as shown in Figure 5. In this position the door is horizontally disposed,

with its lower end projecting out through the doorway to provide a canopy structure. The amount of this projection depends upon the position of the bracket 8 with regard to its distance from the lower end of the door. With this bracket closer to the lower end of the door the door projects alesser distance through the doorway. With this bracket near the center of the door the projection is greater.

The lever and counterweight mechanism may be attached to one or both sides of the door. If such mechanism is attached to one side of the door a heavier counterweight would be necessary, whereas if attached to both sides of the door a lighter counterweight would be sufficient.

By providing means for lifting the door bodily it is possible to lift it above any collection of ice, snow or other material before swinging it transversely of the door opening. By providing a counterweight that will rst move the door vertically in conjunction with the guide and then move it transversely of the door opening, it is possible to utilize a single weight for the compound movement of first lifting the door and then moving it into a horizontal position over the door opening.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention.
