Referring now to the drawings more in detail, wherein like numerals have been employed to designate similar parts throughout the various figures, it will be observed that for the purpose of I illustrating one practical embodiment of my invention I have shown the same in association with a garage structure which I have designated generally by the numeral 20. This structure includes a door opening 22, and positioned on opposite sides of this door opening is an upright member or door jamb 24. Extending downwardly from the roof structure 26 toward the rear portion thereof is a suitable support 28, Figures 3 and 4, and the lower extremity of this support provides a mounting for the rear extremity of the upper section 30 of a guide rail which I have designated generally by the numeral 32.

One of these guide rails 32 is positioned on each side of the door opening, and the upper rail sections 36 are horizontally disposed and merge into curved sections 34 which in turn terminate in vertical rail sections 36. The curved rail section 34 is secured against a bearing or gusset plate 38 which is mounted in any suitable manner against the door jamb 24.- Spaced along the vertical section 36 of the guide rails is a plurality of brackets 40, Figures 1 and 2. One extremity of each of these brackets 40 is anchored to the door jamb 24, while the other extremity is riveted or otherwise secured to the vertical guide rail section 36,as clearly shown in Figure 2. It will thus be apparent that each of the guide rails 32 is rigidly supported within the garage structure,

and that the rail section 36 is vertically positioned in parallelism with its companion upright door jamb 24.

The guide rails 32 provide means for directing the movement of a plurality of hingedly connected

door panels

42, 44, 46, and 48 between a vertical door closing position, as shown in Figures 1,-

3, and 16, and a substantially horizontal overhead position. The door panels are connected together at each extremity by means of similar hinge and strut mechanisms which I have des ignated generally by the numerals. 50, 50a, and 50b. The hinge mechanisms 50 connect the panels42 and 44, and the next adjacent mechanisms 50a connect the

panels

44 and 46, while the mechanisms 50b hingedly join the

panels

46 and 46.

Each of these

mechanisms

50, 50a, and 50b comprises a hinge unit which includes a hinge element 52 which is secured by means of suitable screws or the like to one of the door panels and a companion hinge element 54 which is likewise secured to the adjacent door panel, (see Figures 5 to 7 inclusive and Figure 19). A hinge pin 56 passes through the adjacent cylindrical sections of the

hinge elements

52 and 54, and straddling these cylindrical sections and mounted upon opposite extremities ofthe pin 56 is a shackle or strut member 58. This shackle or strut includes elongated side elements 60 which are connected by a bodyportion 62. This strut member .58 is movable about the pin 56 within predetermined limits, which limits are determined by a lug 64 which is struck out of the body portion or plate 62. This lug 64 extends within a circumferential slot or groove 66 which is provided within the cylindrical sectionrof the hinge element 52, the upward swinging movement of the shiftable strut 58 being determined by the engagement of the lug with an abutment 68 at one extremity of the slot 66 and the downward movement by an abutment 10 at the opposite extremity of the slot. The free extremity of each of the side members 60 provides a mounting for a pin 12 which carries at its outer extremity a roller 14, which roller is shiftable withinthe guide rails 82. The outer or free extremity of the body portion 82 of the shiftable strut is adapted to receive one extremity of an actuating rod; thus the shackle or strut 58 of the uppermost mechanism 50 is adapted to receive the upper threaded extremity of an actuating rod I8 which carries adjusting nuts 18, and the lower extremity of this actuating rod I8 is received by the shackle or strut of the mechanism 50a. The upper extremity of an actuating rod 18a is received by the mechanism 50aand the lower extremity by the mechanism 50b, while the upper extremity of an actuating rod 161) is connected to the mechanism 50b, and the lower extremity thereof is secured to a control mechanism 80, later to be described. These actuating rods I81; and 18b serve to impart upward movement to the movable shackle members 58 as the door panels approach the limit of their door opening position, thereby imparting lateral movement to the

door panels

42, 44, 48, and 48 toward the door jambs 24. In other words, the shackle or strut members 58 and their

companion hinge members

52 and 54 provide a toggle device, and when the shackle members are urged upwardly, the rollers I4 bear against the inner surface 82, Figure 2, and the door panels are positively carried forward and sealed against the door jambs. In this instance, the shackle member serves as a strut which acts between the stationary rail section and the panels so as to firmly secure said panels against the door jamb. The movement of these shackle or strut members 58 is automatically controlled by a panel controlling mechanism 84 which is about to be described. This panel controlling mechanism 84 is similar in many respects to the mechanism shown in the copending application of Douglas A. Wilson, Serial No. 383,301, filed August 3, 1929, but is provided with certain improved structural characteristics which render the same particularly adaptable for use in connection with the panel sealing or closing mechanism forming a part of the present invention. The controlling mechanism 84 includes a pair of

straps

86 and 88, Figures 16 and 19, which straddle the shackle member 58, and which are mounted upon the roller carrying pin I2 of the upper hinge and shackle mechanism 50.

These

straps

88 and 88 are connected by means of a connecting member 90 to a plate member 02, which extends laterally of the connecting member 90 and carries a roller 95. This roller rides along the outer surface of the guide rail and thus guides the connecting member 80 during the shifting of the door panels. Pivotally mounted to the upper extremity of the connecting member 90 is a rocker arm 94, one extremity of this rocker arm 94 having an adjustable panel engagink member 96 and the opposite extremity thereof provided with a U-shaped arm 98, which is formed with a tapered section I00, Figures 16 to 18 inclusive. A pin I02 is positioned so as to engage the arm 98 when the control mechanism 84 is moved forwardly to the position shown by the dotted lines in Figure 16. The engagement of the arm 98 with this pin I02 causes the adjustable arm 06 to be quickly swung into engagement with the uppermost door panel 42 so as to cause said panel to be tightly sealed against the door jamb, as shown in Figure 16. A pin I02a engages the tapered section I of the arm 08, as clearly shown in Figure 18, so as to prevent the inadvertent rearward movement of the panel 42. For a more detailed description of the functional characteristics of certain portions of the panel controlling mechanism 84, reference is made to the aforementioned copending application.

The arm 98 of the rocker arm 84 is connected to the shiftable strut member 58 of the upper mechanism 50 by means of an actuating rod. I04. The lower extremity of this rod I04 is received by the body portion 82 of the strut member, as clearly shown in Figure 19, and the upper threaded extremity of the rod passes through a swivel eye-bolt or member I08. justing and locking nuts I08 are-provided to adjustably control the degree of movement of the rod I04. The swivel eye-bolt I08 and the adjusting nuts I08 are so disposed with respect to each other that no movement will be imparted to the actuating rod I04 until the rocker arm 94 approaches the limit of its panel closing movement. In other words, an upward movement is imparted to' the actuating rod I04 just as the rocker arm is completing its clockwise panel closing movement, Figure 16, and this upward movement which is experienced by the rod I04 is contemporaneously imparted to the strut members 58 of the

mechanisms

50, 50a, and 50b, thereby effecting the automatic sealing of the panels against the door jambs. To instantaneously release the door panels, it is only necessary to impart a very slight upward movement thereto. In fact, an upward movement of onequarter of an inch imparted to the panels is sufficient to release said panels from engagement with the door jambs.

Attention is now directed to the structure shown in Figures 8 to 13 inclusive, wherein I have shown in detail the structural characteristics of the panel controlling mechanism 80 which is mounted at each lowermost corner of the bottom door panel 48. This mechanism includes a bearing plate IIO suitably m'ounted upon the panel 48, and extending outwardly from this bearing plate is a bracket II2 which pivotally supports a strut'member 58a. which is similar in functional characteristics to the shackle or strut member 58 already described. The shiftable strut member 580 is pivotally supported by a pin 56a mounted in the bracket II2, and the freeextremity thereof carries a pin 12a. which supports a roller 14a. Vertically slidable within the bracket II2 is a locking element or plate II 4, and the upper extremity of this plate is connected by means of the actuating rod 18b with the shackle or strut member of the mechanism 50b. The locking member or plate H4 is formed with an outwardly extending finger 8, which is adapted to engage the pin or shaft 12a when said locking member experiences an upward movement, as clearly shown in Figure 10. This causes the lowermost panel 48 to be tightly sealed against the door jamb. When an upward movement is imparted to the lowermost panel, the

Suitable adshackle or strut member- 58a is immediately and automatically released so as to permit the associated elements to occupy the position shown in Figure 11. As the bottom panel reaches the position shown in Figure 13, where it is about to be moved along the curved rail section 34, there is a tendency for the panel 48 to be swun outwardly away from the vertical rail section 84 and toward the door jamb. This lateral swinging of the panel toward the door jamb must be prevented in order to insure suflicient clearance, and this is accomplished by providing an abutment II8 on the locking element II4. It will be noted that this abutment H8 is adapted to be engaged by one edge of the shiftable strut 58a, and this positively prevents the panel 48 from moving toward the door ,1 b. By referring to Figures 9 and 10 it will be seen that the abutment II 8 is positioned well above the shackle or strut member 58a at the time the panel 48 is in its lowermost position, and hence the said shackle'or strut member may be swung sufliciently so as to bring the outer surface of the panel 48 into engagement with the adjacent door jamb. Obviously, numerous other panel controlling or closing mechanisms may be employed without departing from the spirit and scope of my invention, and in this connection attention is directed to, Figures 14 and 15, wherein a modified form of panel controlling mechanism is shown.

The panel controlling or closing mechanism disclosed in Figures 14 and 15 is designated generally by the numeral 80a, and is similar in many respects to the mechanism 80 just described. The only structural features in the mechanism 80a, which differ from the mechanism 80, are the features of the slidable locking member or plate. The mechanism 80a comprises a plate I I4a which is provided at its lower extremity with an extended section I20. As the door panel 48 approaches the limit of its downward movement, this extended or depending section I is carried into engagement with the fioor I22, and as the panel continues to move downwardly, the pin 12a is automatically urged upwardly, thereby causing the panel to be swung laterally toward the door jambs 24. In other words, instead of employing the actuating rod 16b, as described in connection with Figures 8 to 13 inclusive, the modified device shown in Figures 14 and 15 employs the extended section I20. In both devices, the shackle or strut member is automatically moved about its pivotal point in response to the relative movement between the locking member or plate and the door panel. Obviously, means other than the floor and the actuating rods may be provided for imparting movement to the locking means, and it should therefore be clearly understood that my invention is not limited to the specific structure which has been described but is capable of numerous modifications and changes which are comprehended within the scope of the appended claims.

To more clearly understand the operation of the above described door controlling devices, consider, for example, that the door panels occupy their open overhead position. While in this position, the panel lifting elements, such as the counterbalancing springs I24 pulleys I26, and flexible lifting elements or chains I28, are positioned slightly to the left of the position shown in Figure 4. As the panels are shifted forwardly, the lowermost panel 48 is first shifted along the curved rail section 34, and as it is moved downwardly from this curved section, the shackle or strut member 58a engages the abutment II8 of the locking member orplate, as clearly shown in Figure 13. This insures sufficient clearance between the lower edge of the panel 48 and the surfaces of the door jambs. The door panels are successively shifted along the curved section 84 to. thevertical section 36, and the clearance between said panels and the door jambs is sufficient to positively preclude any possibility of binding. In other words, the door panels are freely shiftable without encountering frictional engagement with the door jambs. As the upper panel controlling mechanism 84 reaches the dotted position shown in Figure I8, the U-shaped arm 88 of the rocker arm 84 engages the pin I02, and this causes the upper panel 42 to be quickly swung into closing position toward the door Jambs. During the final movement of the rocker arm, the actuating rod I04 is shifted upwardly a sufllcient distance so as to impart movement to the connected

shiftable strut members

58 and 58a, thereby moving said shiftable strut members from the position shown in Figure 6 to the position shown in Figure 5. It will be noted that the axis of the roller carrying pin 12 can never be shifted upwardly to a point which would be in horizontal alinement with the axis of the pin the lug 84 which limits the upward movement of the shiftable strut member by engaging the hinge abutment 88. This prevents the movement of the shackle or strut members past dead center, or, in other words, prevents said members from being locked in position. Upon imparting a very slight upward movement to the panels, the shackle members are immediately released, thereby permitting the panels to be moved upwardly without encountering any undue frictional engagement with the door jamb. As the uppermost panel is moved upwardly, it is quickly swung 58 by reason of rearwardly by engaging a deflector I30, and when the panels reach the position shown in Figures 4 and 13, the engagement of the shiftable strut members 58a with the abutment II8 of the locking member II4 serves to prevent movement of the panel 48 toward the door jamb, thereby permitting uninterrupted movement of said panel between open and closed positions.

From the foregoing it will be apparent that my invention contemplates the provision of an overhead door construction, in which hingedly connected door panels may beshifted from a substantially horizontal overhead position to a vertical position and automatically sealed against the door jamb in a very effective manner. It is to be noted that the lower sections of the guide rails are vertical, or, in other words, are in parallelism with the inner surface of the door jambs, and by having the lower rail section vertically disposed the door panels'may be freely shifted adjacent the lambs without experiencing any binding action; that is to say, suflicient clearance is presented between the panels and the door jambs so that, even though the panels or jambs are subjected to expansion, warping, or other distortion, said panels may be freely shifted. The fact that my invention provides, in combination with a fixed vertical rail section, door closing means which does not function until the panels approach the limit of their closing movement, enables said panels to have suihcient running clearance during substantially their entire vertical movement adjacent the door jambs. Doors, such as garage doors, are used during all seasons 01' the year, and hence are subjected to a wide range of climatic conditions. Hence there is constantly a tendency for the parts to experience the above mentioned warping and other distortions. In this connection, attention is directed to the fact that I provide connecting means between the various shackle or strut members which are adjustable. This adjustable feature enables the movement, which is imparted to said struts, to be adjustably controlled. In this manner, variations in surface contour of the panels and door jambs may be compensated for, thereby insuring the perfect sealing of the panels against the lambs at all times. As pointed out above, the shiftable shackle members, which are associated with the hinges as well as the lower portion of the bottom panel, provide positively acting strut members which act between the fixed vertical rail sections and the door panels. Only a very slight movement is required to establish the strutting relation of these members, and a similar slight movement is required to release said members. Therefore only a very slight movement, which takes place during the final closing operation of the door panels, is required to effect the sealing of the panels against the 'door jambs. The controlling mechanism associated with the upper door panel provides a very effective means for controlling the movement of the actuating rods, and the manner in which I have provided the U-shaped portion at the extremity of the rocker arm and the tapered section thereof, serves to positively prevent the inadvertent rearward swinging of the uppermost panel when said panel has been moved to its final closed position. My improved door controlling mechanism is not only efficient in operation, but is structurally designed so as to enable -the same to ,be economically manufactured and to be installed with a minimum amount of effort and skill.
