2 Claims.

This invention appertains to new and useful improvements in closure controlling means.

The principal object of the present invention is to provide a door retaining mechanism whereby the door can be retained in closed or fully opened position against self-swinging.

Another important object of the invention is to provide a closure detent whereby the doors of a garage can be fully held in closed or automatically opened position, without manual assistance.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a top plan view of the mechanism attached to a pair of garage doors, showing the doors in open position.

Figure 2 is a top plan view of the mechanism showing the doors held in closed position.

Figure 3 is a fragmentary vertical sectional view showing the mechanism in closed door retaining position.

Figure 4 is a sectional view taken substantially on line 4-4 of Figure 2.

Figure 5 is a fragmentary detailed sectional view-on the line 5--5 of Figure 1.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a garage structure which includes the doorway frame made up of the vertical side members a-a and the top frame member 13. Numeral 6 denotes a beam secured to the horizontal member b and the upper ends of the side members aa and to this is secured the forward portion of the retainer mechanism generally referred to by the numeral 1. The garage doors are denoted by numerals 88 and each is provided with a lug 9 on its inner side. Inwardly connected to these lugs 99 on the forward ends of the elongated arms lfll0 which at their upper ends are pivotally connected by a trunnion II to the roller l2 which operates between the depending flanges of the parallel angleiron guides I3-l3. The forward ends of these angleiron members l3l3 are secured to the intermediate portion of the beam 6 while the rear ends are connected to the intermediate portion of the substantially V-shaped brace member I4 which is apertured at its ends to receive securing means whereby the same can be secured by its ends to a suitable portion of the garage.

Extending laterally from one of the angleirons l3 are the angleiron guide members I5l5 between which rides the roller It, said roller having upwardly and downwardly extending spindles i'l--I8 pivotally connecting the adjacent end of the links l9--20 to the roller I6, while the remaining ends of these links [9-28 are pivotally connected to the upper and lower ends of the aforementioned roller I2. A coiled extensible spring 2! has one end secured to one of the angleirons l3 while its opposite end connects to the roller It. A bar 22 extends rearwardly from the beam 6 and connects the remaining ends'of the angleirons I5-|5.

It can now be seen that the spring 2| in Figure 2 is operative to hold the roller l2 toward the rear end of the guide members l3|3 and in so doing is holding the doors 88 in closed position.

In moving the doors 88 to open position, the doors are pulled open and as this occurs the arms ill-10 move forwardly on the roller I2 which moves the forward ends of the links l92fl laterally of the guides |3-I3. As the roller l2 passes the guides l5l5 the doors can be released as the tension of the spring 2| will snap the doors to fully opened position as the roller I2 is forced toward the forward ends of the guide members Iii-I3, carrying with it the arms |0- I 0. Thus, the doors 88 are held either in closed position as shown in Figure 2 under tension, or in fully opened position as shown in Figure 1, under the tension of the spring 2|.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what claimed as new is:

1. A door retainer of the character described comprising a swingable door mounted in a doorway, a guide extending at right angles tothe doorway, a lateral guide extending from the first mentioned guide, an arm extending from the door and having one end slidably engaged with the first mentioned guide, a link member having one end engaged with the end of the arm engaged in the first mentioned guideway, the remaining end of the link being slidably connected with the second mentioned guide, and spring means normally tending to urge the last mentioned end of the link toward the first mentioned guide.

2. A door retainer of the character described comprising a swingable door mounted in a doorway, a guide extending at right angles to the doorway, a lateral guide extending from the first mentioned guide, an arm extending from the door and having one end slidably engaged with the first mentioned guide, a link member having one end engaged with the end of the arm engaged in the first mentioned guideway, the remaining end of the link being slidably connected with the second mentioned guide, and spring means connecting the last mentioned end of the link to the first mentioned guide, and supporting means for the said guide.
