towards the door frame, when the door reaches itsclosed position, one of said closing devices being capable of being locked for holding all the closing devices in closed position.

Another object of the invention resides in the combination and arrangement of a manually operated closing device with automatic closing devices, whereby a more eiiective closing action is accomplished between the door panels and the door frame.

A feature of the invention resides in a design of closing device that will assure full eifective movement of the panels into closing position with the door frame but will readily compensate for any irregularities in construction or irregularities in the closing movements of the door panels when in use.

Another feature of the invention resides in the use of closing devices that will move the door panels horizontally towards the door frame and capable .of coaction with other; types of closing devices that are capable of giving horizontal and vertical movements to the door panels to assure tight closing of the panels against the door frame,

and tight closing of the panels against the ground or base of the door frame. v

Besides the above, the invention is distinguished in the specific details of construction of the various parts of the door structure, whereby the cost of manufacture is materially reduced while at the same time adding to the eiliciency f the door construction as a unit.

With these and other objects in view, the invention will be better understood from the i01 lowing detailed description, taken in conjunction with the accompanying drawings, wherein:

Again referring to the drawings, illustrating one of the many constructions of the invention, the numeral i designates a door frame of a garage, or any other suitable enclosure, and this frame 0 rests upon a ground base 2.

Associated with the door frame I is the improved door construction, including a door 3, which consists of a plurality of hingedly connected panels d, the number of panels depending upon the area of the opening formed by the door frame I. These panels are provided with overlapping flanges la at their abutting edges and, further, the abutting edges of the panels are hingedly connected together by the improved type of hinge illustrated in Figures 6 to 9 inclusive. The hinge is so constructed as toperform the dual function of a hinge and a guide device for the door panels. To accomplish this dual result, the hinge consists of a pair of metal plates 5 and 6, the former hereinafter identified as the upper plate, and the latter as the lower plate, although a it is to .be understood that this relation of the plates may be reversed. I

The plate 5 is stamped to provide a slot 1 defining a pair of side strips 8 and 9 which are rolled back upon themselves to form ears l0 and II. The plate 6 is stamped and out along the lines l2 and Hi to provide the end strips I 4 and I5 and the intermediate strip IS. The intermediate strip is rolled back upon itself to form a cylindrical ear I L which is adapted to be arranged in the slot l of plate 5 and aligned with ears l0 and II to receive the pintle I8 of the-v hinge, thereby forming a. hinge connection between the upper body of the plate 6. The bearings 23 are formed by rolling back the extreme end portions of the strips l4 and I5. These bearings or tubular members 23 have relatively smooth interior sur- 5 faces so as to allow the free rotation of the shaft 2| journalled therein, which shaft is capable of longitudinal shiftable movement in the bearings. Mounted upon one end of the shaft 2| is a roller 22 adapted to travel in the trackway hereinafter described.

The improved hinge device is connected to a pair of adjacent panels so that the panels may swing relative to each other for the purpose hereinafter set forth.

Secured to the door frame is a supporting frame 23 which, in turn, supports a pair of

tracks

24 and 25, each shaped and constructed to have a lower vertically inclined portion 26; a vertical straight portion 21, a continuation of the portion 26; an intermediate curved portion 23, a continuation of the straight portion 21; and a horizontal portion 23, a continuation of the curved portion 28. These tracks are further provided with flanges 33 and 3| having a guiding engagement with the rollers 22 of the various hinges.

Associated with the upper panel 32 of the set /of panels is an automatic closing device 33 and associated with the bottom panel 34 is an automatic closing device 35. The

intermediate panels

36 and 31 are associated with

automatic closing devices

33 and 33 while the intermediate panel 43 is associated with a manually operated closing device 4|.

The automatic closing device 33 consists of a clip 42 directly bolted or secured to the panel 32 and this clip supports a roller 43 guided by the flanges 3| and 33. Due to the length of the clip 42, and the position of the roller 43, the roller 43 will have a cam action with the curved portion 40 28 of the track when the panel 32 approaches its closed position. ,As a result, the panel 32 is wedged towards the frame I for assuring the effective closing of the upper portion of the door.

The automatic closing device 36 also consists of a clip 44 carrying a roller 45 that is positioned to have a wedging action with the inclined por-- tion 26 of the track when the bottom panel 34 reaches its closed position and, as a result, this panel 34 is forced towards the frame I. Each of the

automatic closing devices

33 and 33 consists of a bracket 46 secured to an intermediate panel, the bracket terminating in a sleeve 41 in which is mounted a pin 43 adapted to have cam action with a cam finger 43 projectportion of the track. Contiguous 'to the cam finger 43, the plate isprovlded with a recess 5| in which the-pin 43 is adapted to be lodged after it has been guided into the recess by the cam action of the cam finger 43; It will benoted from the drawings that the brackets 46 extend lipwardly at a slanted angle from the door, and it will be understood that due to the lengthof said brackets, the pins 43 are yieldably carried with respect to the cooperating cam plates 63 so that each pin 43 resiliently coacts with the cam finger 43 and contiguous recess 5| of the corresponding cam plate to urge the associated door panel towards the door frame with a yieldable force. This coaction between the pin and the cam finger properly forces the door panels towards the door frame and when this is accomplished, the panels are locked in such position due to the coactionof the walls of the recess 5| ing from the cam plate 53 secured to the vertical with the pin 43. To assure pr p l? coaction between the cam finger 43, the pin 43, and the walls of the recess 5|, the plate is provided with slots 52 in which are mounted bolts 53 that are also mounted in slots 54 in the supporting frame 23. Attention is called to the fact that the slots 52 are horizontally disposed, whereas the slots 54 are vertically disposed, thereby enabling the plate to have horizontal and vertical adjustments.

The manually operated locking device 4| consists of a pair of locking bolts 55, one for each vertical edge of the door and each having a double cam action with the tracks so that the set of door panels may be given horizontal and vertical movements in the actuation of the locking device 4|. Each bolt 55 directly coacts with a keeper plate 56 provided with horizontally disposed slots 51 in which are mounted clamping bolts 58 that are in turn mounted in vertical slots 53 formed in the supporting frame 23.

Each track is provided with an opening 63 registering with the opening 6| in the keeper plate. The horizontal wall 62, and the vertical wall 63 of the keeper plate opening 6| are so disposed when the bolts 58 are properly adjusted in the

slots

51 and 59, that they will have the desired cam action with the horizontal cam face 64 and the vertical cam face 65 of the bolts.

The coaction between the walls 62 and 63 and the cam faces 64 and 65 is such that the door panels are simultaneously given movements in two directions, that is, horizontally and vertically, to bring about a tight fitting action between the panels and the door frame and between the lower edge of the bottom panel 34 and the ground base 2.

For the purpose of giving the desired sliding movements to the bolts 55, there is provided an actuator 66 consisting of a link 61 having pivotal connections 63 with rods 63 that are connected to the bolts, the rods being slidably mounted'in the guide bearings 13 arranged contiguous to the keeper plates 56. The link 61 is mounted upon a shaft 1| that,.in turn, has secured thereto an interior handle 12 and an exterior handle 13 for the manual operation thereof. The link 61 is further provided with notches 14 adjustably related with the latch 15'. of any suitable form of lock 16. Due to the arrangement and construction of the notches and their coaction with the latch 15, the bolts may be effectively locked in any of their adjusted positions, thereby compensating for any irregularities in construction or sliding movements of the door in the use thereof.

To complete the invention, there is provided a, lifting mechanism 11 consisting of cables 13 secured to the door panels and travelling over pulleys 13 with one of the pulleys connected to one end of a coii spring 3|, the other end of which is'secured to a portion of the supporting frame 23. In the installation of the door, the rollers 23 are arranged'to' travel between the flanges 33 and 3| of the pair of tracks so that the panels may be flexed relative to each other and caused to travel vertically and horizontally. In the movement of the door panels towards closing position, the wedging action between the closing devices 35 and the inclined portion of the tracks 26 will force the door panel 34, or the lower portion of the door, into tight engagement with the door frame. As this action is taking place, the pins 43 are being subjected to a cam action due to their engagement with the cam fingers 43 which also forces the door or door panels towards the door frame I and conjointly with this action, the

, '2,124,oeo

closing devices 33 are having'a cam action with the curved portion of the tracks for forcing the upper panel 32 or upper portion of the door towards the frame I. Thus .it will beappreciated that the panels are automatically moved into engagement with the door frame. I

As a final operation and, further, to assure the tight engagement of the panels with the frame through the action of the automatic closing de-. vices, the manually operated closing device M is actuated, which gives a further movement of the panels towards the door frame and, further, gives a, movement of the panels downwardly to assure tight engagement of the lower edge of the door with the ground base and a final engagement of the panels with the door frame i.

This manual actuation of the closing device I draws the pins 48 into final tight engagement with the walls of the recess 5! and, further, draws the rollers of the

closing devices

33 and 35 into tight wedging action with the cam surfaces of the tracks. As the manually operated device ll is capable of being locked, it will be appreciated that the locking device 5| performs the triple function 'of' giving horizontal and vertical movements to the door and locking the door panels in vertical and horizontal adjusted positions.

To facilitate proper coaction between the panels in the operation of the various types of closing gressively into engagement therewith, that is to say, the uppermost panel moving into closing contact with the door frame; immediately thereafter, the intermediate panels moving into closing contact with the door frame; and finally, the

lower panel moving into closing contact with the door frame; or, this action may be reversed, with the lower panel first contacting with the door frame, then the intermediate panels, and finally the uppermost panel.

or course, it is to be understood that the details of construction of the various parts may be changed without departing from the spirit of the invention and, therefore, we do not wish to be limited in protection except as set forth in the following claims:
