Turner, Oklahoma City, Okla. Application October 18, 1937, Serial No. 169,704 2 Claims. (Cl. 292—278) 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 where 5 by 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 auto 10 matically opened position, without manual as sistance. These and various other important objects and advantages of the invention will become apparent to the reader of the following speci 15 ?cation. 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 re taining 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 nu merals designate like parts, it can be seen that numeral 5 denotes a garage structure which includes the doorway frame made up of the ver tical side members a-a and the top frame mem ber 13. Numeral 6 denotes a beam secured to the horizontal member b and the upper ends of the side members a—a and to this is secured the for ward portion of the retainer mechanism gener ally referred to by the numeral 1. The garage doors are denoted by numerals 8—8 and each is 4:0 provided with a lug 9 on its inner side. Inwardly connected to these lugs 9—9 on the forward ends of the elongated arms l?—l0 which at their up per ends are pivotally connected by a trunnion II to the roller l2 which operates between the 45 depending ?anges of the parallel angleiron guides I3-—l3. The forward ends of these angle iron members, l3—l3 are secured to the inter mediate portion of the beam 6 while the rear ends are connected to the intermediate portion of 50 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 angle 55 irons l3 are the angleiron guide members I5—l5 between which rides the roller It, said roller hav ing upwardly and downwardly extending spindles i'l--I8 pivotally connecting the adjacent end of the links l9--20 to the roller I6, while the re maining ends of these links [9-28 are pivotally Ol 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 Fig ure 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 8—8 in closed position. In moving the doors 8—8 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 l9—2? lat erally of the guides |3-I3. As the roller l2 passes the guides l5—l5 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 8—8 are held either in closed position as shown in Figure 2 under tension, or in fully opened position as shown in Figure 1, 30 under the tension of the spring 2|. While the foregoing speci?cation sets forth the invention in speci?c terms, it is to be under stood that numerous changes in the shape, size, and materials may be resorted to without de parting from the spirit and scope of the inven tion as claimed hereinafter. Having described the invention, what is claimed as new is: 1. A door retainer of the character described 40 comprising a swingable door mounted in a door way, a guide extending at right angles to- the doorway, a lateral guide extending from the ?rst mentioned guide, an arm extending from the door and having one end slidably engaged with the ?rst mentioned guide, a link member having one end engaged with the end of the arm en gaged in the ?rst mentioned guideway, the re maining end of the link being slidably connected with the second mentioned guide, and spring 50 means normally tending to urge the last men tioned end of the link toward the ?rst mentioned guide. 2. A door retainer of the character described comprising a swingable door mounted in a door 55 2 2,122,220 way, a guide extending at right angles to the doorway, a lateral guide extending from the ?rst maining end of the link being slidably connected with the second mentioned guide, and spring mentioned guide, an arm extending from the means connecting the last mentioned end of the door and having one end slidably engaged with the ?rst mentioned guide, a link member hav link to the ?rst mentioned guide, and support ing means for the said guide. ing one end engaged with the end of the arm engaged in the ?rst mentioned guideway, the re GROVER C.
