1 Claim.

This invention relates to a manually operated closing and locking device for overhead garage doors and, more particularly, to a divisional application of a previously led application, Serial Number 70,736 dated March 25, 1936, and has for its primary object the incorporation in a locking device of a plurality of types of. closing elements whereby the door may be more effectively and positively forced into closed position with the door frame and locked in such position.

4An object of the invention resides in the use of a combination of closing elements which cooperate in a new and eliective manner to give the required movements to the door panels in a plurality of directions towards the door frame upon the door reaching its closed position, said vclosing elements being capable of being locked for holding the door in closed position. .A feature of. the invention resides in the nov-el manner of designing the parts of the manually operated closing device whereby any irregularities in construction or assemblage of the parts, or irregularities in the closing movements of the door panels, may be compensated for to assure full closing of the door against its door frame.

Another feature of the invention resides in a design of closing device in which the parts counction to move the door panels horizontally towards the door'frame, and vertically towards the ground base of the door frame, whereby the door is assured of close contact with its frame and with the ground base.

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

Figure l is a side elevation of the door.

Figure 2 is a perspective view of a part of the locking device.

Figure 3 is a vertical sectional' View through the closing and locking device.

Figure 4 is a cross sectional view of a part of the closing and locking device.

Figure 5 is a front elevation of the keeper plate.

Figure 6 is an edge elevation of the keeper plate and associated elements.

resting upon a ground base 2.

Associated with the door frame is a door 3 consisting of a plurality of hingedly connected panels d, the number ci panels depending upon the area of the opening formed by the door frame l.

These panels are provided with overlapping have a lower vertical inclined portion 2&5, a vertical straight portion 2l, a continuation of the inclined portion 26; an intermediate curved portion Zit, a continuation of the straight portion 2i; and a horizontal portion 29 a continuation of the curved portion 28, as more clearly set .forth and described in copending application Serial Number l 79,736, filed March 25, 1936.

Associated with the inclined portion 26 and attached to the lower panel 34 is an automatic closing device 35 which consists of. a clip it carryy ing a roller that is positionedto have a wedging action with the inclined portion 25 when the bottom panel 34 reaches its closed position, resulting in the panel 34 being forced towards the frame I. The intermediate panels of the door are associated with a locking device which not only functions to force and lock the door in closed position, but to operate with the closing device 35 to move the door downwardly as well as horizontally, to assure the closing thereof in tight position with the door frame and with the ground base.

The locking device 4I consists of a pair of latch 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 the desired horizontal and vertical movements in the actuation of. the locking device lil. Each bolt directly coacts with a keeper plate 5t provided with horizontally disposed slots 5l in which are mounted clamping bolts 58 that are, in turn, mounted in vertical slots 59 formed in the supporting frame 23.

Each track is provided with an opening 60 registering with the opening 6l in the keeper plate. The horizontal wall 62 and the vertical wall 63 of the keeper plate opening 6l are so disposed that when the bolts 58 are properly adjusted in the slots 51 and 59, they will have the desired cam action with the horizontal cam face @t and the vertical cam face 65 of the bolts 55.

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

For the purpose of giving the desired sliding movements to the bolts 55 there is provided an actuator B6 consisting of a link B1 having pivoted connections 68 with the rods 659 that are connected to the bolts, the rods being slidably mounted in the guide bearings 10 arranged contiguous to the keeper plates 56. The link 61 is mounted on a shaft 'H that in turn has secured thereto an interior handle 'l2 and an exterior handle 13 for the manual operation thereof. The link 61 is further provided with notches 'I4 adjustably related with the lock bolt l5 of any suitable form of lock i6. Due to the arrangement and construction of the notches and their coaction with the lock bolt l5, the latchingY bolts 55 may be effectively locked in a number of adjusted positions, thereby compensating for any irregularities in construction and assemblage of the parts of the lock, and sliding movements of the door in the use thereof.

To complete the invention, there is provided a lifting mechanism Tl consisting of cables 18 secured to the door panels and each travelling over pulleys 19, with one of the pulleys connected to a coil spring 8l, the other end of which is secured to the supporting frame 23. In installing the invention, the rollers 22 are arranged to travel in the pair of vguide tracks so that the panels may be flexed relative to each other and caused to travel horizontally and vertically. In the moveient of the door panels towards closed position, the wedging action between the closing device and the inclined portion of the track 2B will force the lower portion of the door towards the door frame, and this closing action of the lower portion of the door is effectively increased to assure tight closing action of the door frame through the manipulation of the manually operated locking device which, when operated, gives further downward movement to the door, to increase the cam action between the closing device 35 and the inclined portion 36 and further forces the door horizontally towards the frame. This is accomplished through the arrangement of the cam faces of the latching bolts and their coaction with the walls of the locking plates in the manner herenbefore set forth.

I am aware of the fact that locking devices have been heretofore used with garage doors, but their designs are such as to provide only horizontal displacement of the door, whereas my locking device is so designed as to provide not only horizontal displacement of the door but also vertical displacement so that the door may be simultaneously moved into closed position with the frame and also into engagement with the ground base. I am also of the opinion that I am the rst to construct the locking device in the novel manner above set forth, and to associate the same with a self acting closing device whereby the closing action of the latter may be manually increased in the final closing of the door.

What I claim is:

In an overhead garage door movable on guide tracks to an initial closing position and then to a final closing position towards the door frame and Vtowards the ground, a mechanism for moving the door from its initial closing to its final closing position comprising: devices slidably carried by the door an-d each having two right angularly disposed camming surfaces, one of said surfaces being disposed at an angle to the door frame and the other of said surfaces being disposed at an angle to the ground; means including elements mounted in the tracks and positioned thereon to be engaged by said devices when the door reaches its initial closing position and to coact with the camming surfaces of said devices for simultaneously urging the door towards the frame and towards the ground, thus moving said door from its initial closing position to its nal closing position; and means associated with said elements for their vertical and horizontal positioning with respect to said devices whereby to regulate the cam actions of the latter in simultaneously urging the door towards the frame and towards the ground.
