A TTOR/VEYS Patented May 1%. i937 some noon cowsrauorrou Julius ll. Byrne, Detroit, Mich. Application November 11, 1935, Serial No. 49,306 8 Claims. (or. 20-19) The invention relates to door constructions and refers more particularly to door constructions for use in warehouses, airplane hangars and the like.

One of the objects of the invention is to provide an improved door construction which is opened by raising the same and in which the door moves bodily vertically during the first portion of the raising movement'and then swings I toward horizontal positionf Another ob ectis to so construct the door construction that it positive guiding'means. A further object is to provide an improved means for guiding the door during its raising and lowering movements. 7

These and other objects of the invention will become apparent from the following description. taken in connection with the accompanying drawings, in which Figure 1 is an inside elevation of a door construction showing an embodiment of my invention;

Figure -2 is a cross section on the line 2--2 of Figure 1;

Figures 3 and 4 are cross sections on the lines 3-3 and 5- 3, respectively, of Figure 2;

Figure 5 is a view similar to a portion of Figure 2, showing another embodiment of my invention;

Figure 6 is a cross section on the line 5-6 of Figure 5; 1

Figure 7 is a view similar to Figure 2 showing another embodiment of my invention.

As illustrated in the present instance, the door construction is for use in warehouses. The door of the embodiment shown in Figures 1, 2, 3 and i, has a metal frame with the top and bot tom rails 2 and 2' respectively and the upright rails 3. The door is movable bodily or as a unit and is adapted to he opened by being raised. The door is so mounted that it moves vertically up- Wardly during the first portion of its opening movement and then swings or tilts about a horizontal axis with its upper edge movable rearwardly during the remaining portion of its opening movement. The door has secured to its end upright rails the rollers i which; are located intermediate the upper and lower edges of the door and which engage suitable upright guide channels secured to the jambs at the sides of the door opening.

To open the door, I have provided the flexible linear members 5, such as steel cables, there being three in the present instance. These linear members extend in front of the door when closed and have their lower ends secured to the door by suitable means. such as the clevises 6, which are located preferably near the vertical center of the door. In this connection, the rollers i are located with respect to these clevises to secure prac tical operating clearance for the clevises. The linear members extend over the sheaves l which are mounted upon the framework of the building and are located above the door. Suitable counterweights for the door are secured to the linear members and the linear members. may be actuated either manually or by 'power to eifectopening and. closing of the door. With this arrangement, the linear members in opening the door tend to tilt the door in a direction such that its upper edge will move rearwardly.

The head guide or track construction for the door 1 comprises the arms or links 8 which have their lower. ends pivotally'connected to one of faces of the upper portion of the door. In the present instance, there are two armsor links, one being at each end of the door. Each of these arms or links is pivotally connected to the bracket 5. extending rearwardly from the door frame. The upper end of each link is provided'with the upperand lower pairs of rollers l8 and H respectively, which are spaced longitudinally or vertically of the link. For cooperating with each arm or link, there is the head track it which is T-shaped in elevation and which is located above the door in all positions. Each head track has the vertically extending track portion 83 and the horizontally extending track portion it which extends rearwardly from the vertically extend ing track portion and connects thereint'o intermediate its ends. The horizontally extending track portion is parallel to the path of movement of the door. The vertically extending track portion forms in eifect the upper and lower track parts l5 and 16 respectively and' the horizontally extending track portion in efiect connects into the upper end of the lower track part. Both the vertically and horizontally extending track pol tions have the same cross section, as illustrated in Figures 3 and 4. The verticallyextending track portion'opens rearwardly and the horizontally extending track portion opens downwardly. The upper part orweb of the horizontally extending track portion is also cut away at ii to receive the portion of the arm or link above the lower rollers it when the arm or link is in angular position, such as illustrated by the dotted lines of Figure 2. j g I In operation and with the door closed, upon up= ward pulling of the linear members the arms or links will first be moved vertically 'by reason of their upper and lower rollers being positively guided by the vertically extending track portions Eli oieach head guide or track. As a result. the first portion'of the opening movement of the door is in a vertical direction. However, when each link is moved upwardly so that its lower rollers register to horizontal position, as indicated by'the dottedlines in Figure 2. g

In the modification shown in Figures and 6. the parts are so constructed that the'same operation is secured. However. in this modification there are supporting or guiding plates", located above the door and extending transversely thereoi and parallel to the path of movement of the door.

Each plate is provided'with the T-shaped slot having the verticaiiyextending portion Ii and the horizontally extending portion '22 which connects Y into the vertically extending portion intermediate its ends and which extends rearwardly therefrom.

The longitudinally or vertically spaced upper'and lower rollers 28 and 24 respectively upon the arm or link {I are engageable in these portions of the slot in the same manner as the corresponding rollers with their vertically and horizontally extending track portions. illustrated inFlgur'es 1' to 4 inclusive.

The modificationillustrated in Figure 7 has the same general arrangement of parts as that illustrated in Figures 1 to 4 inclusive. l-lowever; in this modification the arms or links 2' corresponding to the arms or links 8 are located inwardly beyond the door 21 when the latter is in closed position to thereby enable more effective sealing between the jambs oi the door frame and the ends oi the door. The headtracks 2a are located inwardly beyond the inner face of the door and at an elevation above the door to provide for positioning the arms or links in the desired relation to the door.
