6 Claims.

This invention relatesto an overhead door structure and to: hinges employed therewith. The invention is particularly applicable to doors of the panel type connected by hinges, which are employed for garages and for other types of buildings. The hinge structure is also applicable to other uses;

In an overhead door type of construction, the panels of the door, when supportedinaclosing position for the doorway lie substantially in a vertical plane. The guide tracks, however, for receiving the rollers carried by hinges connecting the panels, are inclined upwardly and inwardly so that there is a'gradually increasing space between the tracks and the vertical door as the tracks rise. To provide for such increasing space; individual hinges have been employed for connecting the panels at different heights so as to support the roller at varying distances-from the door. Such hinges are often misplaced or are not correctly brought together in a set, with the result that there is considerable loss of time in the. assembly of the door structure with the tracks. Further, the structure is very expensive because the manufacturer is required to make different hinges requiring separate tools and separate operations. Further, the'hinges often do not fit the requirements of the specific structure andspecial adjustments have to be made inv order to'assemblethe door'with the track.

An object of the present invention is to provide a panel door and hinge structurewhich may be readily assembled and in which a single form of hinge may be used throughout the entire height of the door. A still further object is to provide, in combination with the panels of an overheadv type of door, a hinge structure permitting the shifting of the wheel-supporting shaft at varying distances laterally of the door so as to fit the door to guide tracks which may vary from normal inclinations. is to provide a hinge structure for supporting the panels of an overhead type of door, wherein a shiftable sleeve is supported in varying spaced Yet, another obie'ct Figure 1 is a vertical sectional view of a structure embodying my invention; Fig. 2, a perspective view of the hinge structure employed; Fig. 3, a broken enlarged rear view showing the hinge structure applied to two door panels and supporting a roller within a guide track; Fig. 4, a vertical sectional view, the section being taken as indicated at line 4' of Fig. 3; and Fig. 5, a detail sectional view, the section being taken as indicated at line .5 of Fig. 4.

In the illustration given, Iii designates a door frame, and [I designates the side wall of the building supporting the guide track l2. It will be understood that a similar track i2 is supported at the opposite side of the door by suitable frame supports. The track I2 is provided with the usual inwardly-turned flanges I3 for retaining the roller 14 within the track.

The segmental door in the illustration given is indicated generally by the numeral I5. The door is composedof panels 16, which may be formed in any suitable way. In the illustration given, the panels consist of a central strip received within frame border strips l l. The border strips ll are connected by hinge structure l8.

A cable l9 connected to the lower portion of the door extends upwardly and over a pulley 20,

the upper end of the cable being connected to a coil compensating spring. Since such compensating structure is well known, a detail description herein is believed unnecessary. The hinge structure 18, as shown more clearly in Figs. 2 and 5, comprises an upper section 22, having openings 23 for securing the same to a door panel and having also downwardly and inwardly turned flanges 24. The flanges 24 have openings therein with the edges thereof turned inwardly, as indicated at 2-5. The openings receive a fixed tube or sleeve 26 forming the pivot for the structure. If desired, the corner portions of the hinge section 22 may be pressed inwardly, as indicated at 21, to strengthen the structure.

The lower hinge section 28 is also provided with openings 29 adapted to receive screws or other means for fastening the section to a door panel. The section. isprovided with parallel and relatively wide flanges 30, which extend rearwardly from the main body of the section. The flanges 30 are apertured at 3| to receive the fixed pivot tube 26', as shown more clearly in Fig. 5.

In the illustration given, each of the flanges 30 is inclined rearwardly and upwardly, asshown more clearly in Fig. 4, and is provided with a number of spaced openings. An inner row of openings 32 and are in diagonal alignment With the fixed pivot sleeve 25', as indicated in Fig, 4. Anouter series of openings 34, 35 and 36 are aligned so as to extend slightly outwardly of the first row of openings. The laterally spaced openings thus provided, with the exception of the openings receiving the pivot tube 26, are adapted to receive a movable sleeve or tube 36. The tube 31 has one end of normal diameter receivable within the openings 32 to 3b, inclusive, while the other end of the sleeve is outwardly flared, as indicated by the numeral 38.

Received within the sleeve 31 is a shaft 39 supporting a fixed collar 49, as indicated more clearly in Fig. 5. The collar 40 is provided with a groove adapted to receive the ball bearings 4i and upon the race 42 about the ball bearings is mounted a roller structure 43, Thus, the roller structure 43 is free to rotate about the ball bearings 4| but is fixed with respect to longitudinal movement upon the collar 40 of the shaft 39.

The shaft 39 is also adapted to be received within the fixed tube 26, as indicated in dotted lines in Fig. 5, so that the roller-bearing shaft 39 may be moved successively into the sleeve 31 carried by openings 32, 33, 34, 35 and 36, and may also be introduced into the fixed tube 26.

In the assembly of the door with respect to the inclined track 52, it will be noted that the hinges [8 may all be alike and that the only adjustment therein is in the positioning of the tube 31. For

the'lower hinges, the tube 31 will be placed within the inner openings 32 or 3 3, while as the hinges are left at higher elevations, the sleeve 3! is moved to the outer groove of openings. Thus, the roller I4 is supported at varying distances rearwardly of the door so as to support it in alignment with the guideway 12 at the different elevations.

Should there be slight irregularities in the inclination of the track caused by irregularities of the main structure, the hing flanges illustrated provide means for varying the outward positioning of the rollers to fit such irregularities. Further,'if a need for adjustment should later occur for any reason, the sleeve 37 may be readily removed from the aligned openings receiving the same and inserted into another pair of openings which place the roller in the desired alignment with the track.

While I prefer to flare the end of the tube 31 on one side, it will be understood that any suitable enlargement may be provided which will serve to lock the tube against lateral movement.

The relatively wide flanges on both of the hinge sections provide a support for the pivot 26 at a point well to the rear of th front panels of the hinge. Further, by using the fixed tube 26 as the pivot tube and for receiving the roller-equipped shaft, such tube becomes an optional bearing for the shaft in a graduated alignment or spacing from the other openings which receive the removable tube or sleeve 31. The wide flanges of the structure extend outwardly past guide track l2 and protect the openings between the flanges 13, while at the same time providing laterally-spaced openings for receivin the removable sleeve 37.

The structure is extremely simple, permits the assembly of the door with facility and without requiring specific types of hinges for different elevations, while at the same time permitting any selected variation in the angle between the door and the inclined track or guideway.

While in the foregoing specification I have set forth one embodiment of the invention in great detail for the purpose of illustration, it will be understood that the details of such structure may be varied widely by those skilled in the art with out departing from the spirit of my invention.
