channel strips 22 and the upper end of the door is suspended from the tracks I4 through the rollers I9, aXlesZll,l and weatherstrips 2l welded.`
on the channel strips 22. The lower end of the door is pivotally connected through the link arm 24 with weatherstrips 28 secured to the"`doo`r jambs. The door is thereby mounted in the doorway for swinging movement from the lclosed very tical position shown in'Figure 1 through the'intermediate open position shown in Figure 2, to a fully opened overhead position lying horizontally parallel ywith the tracks I4. kThe link arms 24 will swing about their pivots 2l from downwardly extending position, shown in Figure 1, to upwardly extending position forholding thebottom end of the door adjacent the lintel l2. lThe double pivots `32 and 34 for the upper end of the spring are arranged so that the spring `will have .a Straight upward pull on the door in closed vertical lposition to prevent slamming of rthe door into closed positionand an inward pull on the door in overhead position to hold the door open. Y
In order to lock the door in closed position', nippel-devices bestshown ina-Figures l, 3 and 4 are provided on the inner face of the door I adjacent the side edges thereof at levels beneath the pivotal axes 2'Iffor the door. .AS shown in Figures 3 and 4, a plate 31 is Awelded on the inner Yflange 22a of the channel strip and projects therefrom over the door to be secured tothe door l0 by means of screws or the like. Theplate has an offset portion 31a overlying and welded to the iiange 22a of the channel strip 22 and, to permit full seating of the flange 22a on the weatherstrip 28,` the'weatherstrip 28 has an offset localized portion, 28a thereof receiving the forwardly projecting en dr'la of the plate. The arrangement is such that the weatherstrip 28 will contact the flange: 22a of the channel strip along its entire length except at the localized portion 28a thereof. This .portion 28a thereof will contact the plate portion 31a. a
Raised portions 31D are formed on the plate in spaced opposed aligned relationship to define pivf ot supports for a flipper member 38. The ipper member 38'has an oifsetfront end portion 38a for` engaging the weatherstrip 28. Ears 38h are provided on the sides of the flipper in spacedrelation from the end 38a thereof and a coil spring 39 is anchored at one end to each ear 38h and at the other end to a .tang `31e turned up from the edge of the plate 37. The springs 39 pull the flipper 38" to thedotted line positionshown in Figure 3, in which position the kilipperwill clear the inner edge of the weatherstrip 28. I .l
A slide bar 40 is -slidably mounted through a` slot in an upstanding flangc'S'ld of the plate;4 and .through an aligned slot in an upstanding ear 37e yof thee/plate. Y
The bar 40 has an upturned end portion 40a foracting as a presserfootto slide over the ipper 38l andk depress it into locked .position as shown in Y i Figures. As indicated by the dottedlines in Figure 3*, the bar 40 rocksl relative to the plate31 as it is moved from iiipper-releasing position shown in dotted lines to flipper-locking position shown in solid lines. ,'This Arocking action provides a` wedge for securing the nipper in locked position. The inner end of. thebar Dis offset as at 4019 and the offset portion is apertured to receive an f actuating rod 4 I A Cotter pin l2 retains the rod in the aperture of the offset portion 4912. The rod 4! extends along the inner face of the door-k as best shown in Figure l, to an actuating bar k42 of a lock device 43 secured on the inner face ofthe door.
The device 43 has a handle 43a which, when turned, draws the bar 42 inwardly to pull the rod :lllv and effect a sliding of the bar 40 to a position so that the spring 39 will release the flipper 38 I from locked position. A similar bar 62a' actuates a similar rod lla to the lock bar 4E! of the other locking device.
The flippers 38', upon being forced to lockin position by the bars d, serve to pull the door into a fully closed position in the event that the door v has not been fully closed,A since the offset portions locking position against spring` action by means of presser feet or lock bars. The flippers are adapt-' i38a of the flippers will engage the weatherstrips bent to provide depressed portions 24h in alignment with the flipper plates 31 and actuating bars when the door is in closed position, so that suicient clearance will be obtained for the locking device. a
From the above descriptio sit should be understood that this invention now provides locking' devices composed of flippers which are spring-impelled to open position and are actuated to closed ed to engage doorjambs of a doorway for pulling a door intofully closed position, `When'the lock" bars ork presser feet actuate ltheaiiippers.against q the spring action,l thefiippers are locked against further movement and the door .is locked in the doorway.
It will, of course,y be understood that various de- Y tails of construction may be varied through a wide vrange without departing from the vprinciples of this invention, and it is, therefore, not the purpose I claim as my invention:
1. In an upward acting door construction ofthe type including adoor tiltably mountedv in a doorway, an 'improved lockingl means comprising," weatherstrips adapted to overlie the inner face of the door at the side edges of the doorway, offset pockets, formed on said weatherstrips, plates adapted'to be mounted on the inner face of the y door and having offset mating portionsarranged to project into said pockets when the door is closed in full, engagement with said weather'strips, iiip-l pers pivotally mounted on saidv plates and feacli having an arm'portion adapted to overlie the weatherstrips in thrusting engagement therewith, springs stretchedbetween said plates and said flippers for vpivoting the flipper arm portions to extend inwardly from the side edges of the door,'` lock bars slidably mounted on said plates and having offset free ends constituting presser foot'portions arranged to slide over and depress saidfiiippers against the biaso'f. said springs, and'means retainer at a predetermined aligned position, an
arm member pivotally mounted on said plate and extending beyond said one edge of said door to engage a portion of the retainer overlying the doorway, biasing means normally urging said arm member inwardly of said one edge of said door into clearance relationship relative to the portion of said retainer overlying the door, guide means on said plate, and a slidable actuating bar carried byy said guide means, said actuating bar having a pressure foot formed at one end thereof to engage said arm member in wedge relation, whereupon selective reciprooation of said bar will wedge said arm to clamp said door against said retainer in locked closed position,
