1 2,893,728 VENT LOCKING MEANS FOR AWNING TYPE WINDOWS Morton Tucker, Hialeah, Fla. Application June 25, 1958, Serial No. 744,411 2Claims. (Cl. 2;6'8--1 1 1) 'This invention relates to window devices and particularly to that type of window device commonly recognized in the industry as an awning type window and that is composed of a plurality of horizontally pivoted and vertically swinging vents that are movable to -and from an overlapping relation with respect to each other.

Window devices of the above noted characters have generally had one outstanding fault, such :being the absence of any definite locking means for the several vents that prevents unauthorized movement of .the vents United States Patent and, with the lower lock member having cam surfaces that are first engaged by a ,pin carried by crank farfms embodied in 'the vent closing mechanism and whereby the crank arms when movable inwardly in .a closing action of the vents, cams the lower locking'devicejupwardly, and through the medium of links 'between'thelocking devices, the locking devices are simultaneously swung :u'pwardly so that a locking recess is presented to .receive pins'carried by the vents when the vents are movedto substantially the fully closed position and, *wiithithe lower locking devices being additionally 'cammed downwardly fwhen the vents have reached their approximately closed position, so that theilower locking devices are forced carrying the "upper lock devices also n wnwe-r619 and forcing all of the-lock devices simultaneously The locking devices as above noted also function to be automatically =released"from the 'pins *oithe ventsupon t'lre s'tart oftheswinging movement df-the cranks tci move *theseveral vents toan open position, such initial rel'ease' "ofltihe {locking devices being necessary and, it shouild be understood that the initial movement of tlie Cranks and their cam actuating pins' permits the cr nksm travel a distance ca able of c'am'ming the tower lock neengagement with the pins carried by ithe ice Figure 5 is a side elevation of an actuating latch, also {illustrated in Figures 3 and 4, but illustrating the latch in the initial movement to move the several latches in a direction to release the window vents,

Referring specifically to the drawings, the numeral 5 designates extruded jamb forming members, and the numeral 7 indicating an extruded-connecting member for the lower ends of the jambs, all preferablyvformed of aluminum and assembled to form an open frame. The several members each are provided withan inner stop -8, forming an abutment for inner flange members 9 of vent frames 10, and with the frames 10 having circumferential flanges 11 that overlie and abut reveal portions -12 of the frame members and whereby to effectively weather the vents with respect to the frame when-in the fully closed position. Each of the vents, of which there may beany :desirable number, carry :hinge 'elementsl3 'at their upper ends, and .with .the hinge elements 13 .being pivotally connected at 14, to operator :bars 15, that are vertically slidable under the influence 'of links 16, pivotally connected at 17 to the'operator bars and also 'pivotally connected at '18, to 'crank arms 1 9 the construction being duplicated at the opposite sides of the window. The crank arms 19 are .fixed upon a cross shaft 20, horizontally disposed through the sill member rices upwardly, prior to the movement of the vents' e t:

geared operator, not shown. fulcrumed to swing in .a vertical .positions, by fulcrum .bars (not shown.) .and customary .in windows of this type. The mechanism 'so far described is conventional and does not constitute a .part of the invention. Each of the vents 10 upon their opposite ends, are provided vwith projecting pins 24,- while the cranks 19 are provided with projecting pins '25.

Pivotally connected to the inner spacedwall .7a o'f the jambs 7 are actuating latches 26. Thelatches .26 are pivoted at 27, to swing in -a verticalplane. The latches 26 function to lock thelower vent and .to also actuate upper latches to and from .a locking position with respect to upper vents. The latches 26 are double faced, embodying upon one side, a downwardly open groove 28, The groove 28 :functions to receive-a :pin 24 upon the adj'acent end oftthe lower vent 'and, when the latchisrin a :fullylowere'd :posi- The several vents. are arc to open and closed don, the .pin 24 will be fully engaged within the slot 28.

also disposed in the path of movement ofth e pins carried bythe cranks 19. Upperlatches '33, arepiyota'llly supported at 34 upon the wall section 7aand inthe. same vertical ,plane as the latches 26. 'The slotted at 35 and-the slots35 opendownwardlytoconr latches 33 are inunicate with a 'bevel surface 36 thatreceivesand .cams adjacent pins .24 intothe slots 35,.should-the window be partially away from a full seating position and the cam the -.windowinto actuating latches and one upper locking l atch"has-.been

illustrated although, it will be apparent wat additional latches will be cmp cycd nhe e additiqnal;t sntsratezs quired for a particular window structure. The latches 26 and the latches 33 are connected together by elongated links 37, pivotally connected tothe latches 26 and 33, as at 38 and 39. It will be apparent, that any movement of the latch 26 will be imparted to the upper latches 33, both to and from a locking position.

In the use of the device, with the parts illustrated, as in Figure 4, when the vents are to be shifted to the open position, the shaft 20 is rotated, causing the cranks 19 to move outwardly. Since in window constructions of this type, there is an initial lost motion between the cranks and the window operating linkage, it follows, with this lost motion, the pins 25 cam against the upper walls of the cam grooves 31, causing the starting release movement of the latches 26, such being shown in Figure 5. A further motion of the cranks 19, causes the pins 25 to swing the latches 26 upwardly, and as in Figure 6, the latches 26 have been moved upwardly sufiicient to clear the pins 24 from their respective grooves 28 and 35, permitting the cranks 19 to continue the opening movement of the vents. No means has been provided to retain the latches in the release position other than the usual frictional engagement of the pivotally connected parts thus, there is a possibility that the latches may drop downwardly after the window has been fully moved away. Assuming the latches are in the lower position as illustrated in Figure 3, when the window is being shifted to a closed position, the cranks 19 swing inwardly, causing the operator bars to move upwardly, carrying with them the pivots 14, the hinge elements 13 and swinging the vents downwardly on their fulcrum levers. As the cranks continue their inward movement, it will obviously become apparent that the latches must be moved to an open position to receive the pins 24. To be sure that the latches will be elevated to receive the pins 24, the inward swinging movement of the cranks 19, carrying the pins 25, cause the pins to first engage the cam edge 30, shifting the latches 26 upwardly and, through the linkage 37 moving the upper latches 33 in a correspon"- 1g manner, pre-' senting the opening of the grooves 28 and 35 to the line of movement of the pins 24. This initial movement has been shown in Figure 7. When the pin 25 engages the dwell portion 32 of the latches 26, the latches remain relatively stationary to permit of the full closing movement of the vents and, as the pins 25 enter the cam groove 31, they bear against the lower edge of the groove, forcing the latches 36 downwardly upon their pivots 27 and,

through the medium of the links 37 force the latches 26 and 33 to move downwardly over their pins 24 to a full seating and locking engagement within the grooves 28 and 35, thus securely holding the several vents at each end against any unauthorized movement outwardly.

It will be apparent from the foregoing that a very novel form of latch means has been provided for effectively latching the opposite ends of vertically swinging vents in a fully closed and weathering condition. The latches are mounted within the well known frames of aluminum awning type windows and offer no interference to the free movement of the conventional mechanism employed to actuate the window mechanism. While the latches have been applied to one specific form of window device, it will be clearly apparent that it is not restricted as to its use and readily adapts itself to substantially all of the vertically swinging awning type window vents. The several latches, including the actuating latches and the upper locking latches are cheap to manufacture and are assembled within a window frame with a minimum of effort.

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claims.
