assignors to Kewanee Manufacturing Company, a corporation of Iliinois Filed .lune 4, 1963, Ser. No. 285,532 2 Claims. (Cl. 20-53) This invention relates to window structure combinations of the type commonly employed for basement windows and, more particularly, is concerned with a simplified locking arran-gement for such structures that prevents accidental opening thereof and that cooperates in holding the window sash against rattle.
In the usual basement window installation, a window frame is embedded directly in the concrete foundation wall and defines a window opening bordered about its periphery by a fore and aft inwardly facing sash stop at -a location intermediately of fore and aft extremities of the window frame. A sash frame of substantially less dimension in the fore and aft direction is arranged to seat in closed position within the window frame to span the window opening and abut the sash stop.
The principal object of the present invention is to provide a simple clip type lock arrangement mountable on the sash to engage an abutment provided on the window frame.
Another object of the invention is to provide a sash lock arrangement of this type in a window structure combination having a base mounting pocket of tapered form to receive the sash under resilient loading developed by a resilient type lock, thereby preventing rattling.
Another object is to provide a separate clip of spring steel that is resiliently yieldable to effect lock release.
Other objects and advantages of the invention will become apparent during the course of the following description.
ln the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:
FIG. l is an elevational view of a window structure combination as seen from the inside looking out;
FIG. 2 is an enlarged fragmentary sectional View taken through the frame as indicated by the lines 2 2 on FIG. l, with mid-height portions of the frame omitted;
FIG. 3 is an enlarged fragmentary sectional view taken on the lines 3 3 of FIG. l with mid-width portions of the structure omitted;
FIG. 4 is an enlarged detailed view of a sash lock and is taken on the lines indicated at 4 4 of FIG. l; and
FIG. 5 is a perspective view of the lock.
For purposes of disclosure the invention is herein illustrated in FIG. l as embodied in a basement-type window structure, designated generally as 1t), in which a sash frame 11 seats in closed relation within a metal window frame 12 which is intended to be cast in place in a concrete foundation wall (not shown). The window frame 12 delines a window opening bordered about its periphery by a sash stop S (see FIGS. 2 and 3) located intermediately of the fore and aft extremities of the window frame.
Thus, the window frame 12 is formed from spaced pairs of horizontal and vertical rails to provide a head 12H and a sill 12S connected by vertical jambs 12J to collectively define the window opening and sash stop. The sash frame 11 is comprised of correspondingly spaced pairs of horizotal rails 11H and 11S and vertical rails 11i, with these sash frame rails being of substantially less fore and aft dimension than the window frame rails 3,196,497 Patented July 27, 1965 ice and arranged to seat in closed position within the window frame to span the window opening and abut the sash stop S. The sash rails 11H, 11S and 11] are preferably of L-shaped cross section and each presents a fore and aft inwardly directed planar flange. An intermediate vertical rail 11T of T-shaped cross section completes the sash framing.
In the window structure 10 illustrated herein the sash frame seats at a location in the window frame intermediately of fore and aft extremities thereof and undergoes swinging movement towards and away from fully closed position in the window frame. A lock 13y is shown mounted centrally on the upper sash rail 11H in straddling relation to the leg flange of the intermediate sash rail 11T. The head rail 12H of the window frame is provided with an internal marginal abutment surface 14 facing outwardly through the window opening at a location spaced slightly inwardly of the inner extremity of the sash flange and functions as a keeper for cooperation with the lock 13 when the sash frame 11 is seated in closed position in the window frame 12.
A hinge stop arrangement is provided to accommodate swingable mounting of the sash frame 11 between closed position and one or more partially open positions and to provide for total removal of the sash frame 11. Accordingly, each vertical sash rail 11] has a laterally projecting hinge pin 15 at a lower region thereof and each lVertical .window frame rail 12] has internal marginal abutment structure, designated generally at 16, at a corresponding lower region thereof and presenting a generally fore and aft outwardly facing guide Wall 16W spaced inwardly in a fore and aft direction from a corresponding portion of the sash stop to define therebetween a generally vertical entrance trackway T for the corresponding hinge pin 15. The abutment structure 16 has an irregular slot 16S provided therein and opening outwardly in a generally fore and aft direction at the base of the guide wall `16W which, in effect, presents an upper corner bounding the slot.
In the preferred arrangement illustrated herein, the rails are formed steel sections and therefore the abutment 14 and the abutment structure 16 are punched out embossures from each corresponding rail section.
Both the slot 16S and the hinge pin 15 are spaced above the lower edge of the window opening to cooperatively provide an intermediate hinge region controlling partially open positions for the sash. For this purpose the slot has boundary surfaces that include a generally upwardly facing fore and aft extending guide surface 17 leading from the trackway, a contoured surface 18 leading from the inner extremity of the guide surface in a direction generally downwardly and inwardly and then in a direction generally upwardly to define a hinge socket that may receive and retain the hinge pin 15 to support the sash frame at a `first partially open position.
Preferably, the slot 16S is bounded by a further guide surface 19 leading from the inner extremity of the hinge socket in a direction generally upwardly and inwardly and a further contoured surface 20 leading from the extremity of the guide surface in a direction generally downwardly and inwardly and then in a direction generally upwardly to define a second hinge socket for receiving the hinge pin land thereby supporting the sash frame at a further partially open position. This sash frame position is illusin phantom lines in FIG. 2, and -it will be noted that for such position the lower end of the sash frame abuts against a lower region of the sash stop S, resulting in a stable support arrangement for the sash frame at this intermediate position. A similar support arrangement obtains where the sash frame has its hinge pins engaged in the hinge sockets defined by the surfaces 18.
'To install the sash frame 11, it is entered generally downwardly into the window frame along a direction inclined slightly outwardlyV to guide eachpin V15 downward- 1y throughrvits, corresponding trackway to a position im-f During mediately outwardly of its corresponding slot. final closure movement of the sash frame, itswings about the line of support established between the lower sash rail 11S and the sill 12S, and the'ilock'l is enabled to enter 'beneath the abutment surface 14 to `finally snap into engaged position confronting this abutment surface when the sash frame-is fully seated within the window frame. The window sill 12S. has ,an outwardly sloped intermediate wall 12W Vinwardly of the stop S and cooperating therewith in defining a basepocket 21 tapering downwardly to a region narrower than the sash rail 11S to provide better control over the swinging closure movement of the sill. Moreovenrthe lock 13 by reaction with the underface of the head rail 12H normally urges the sash frame downwardly during Vfinal closing movementY to :seat the sash frame forceablyV in wedging engagement in the pocket 21 to thereby prevent any tendencey tov rattleor shake. i i Y The lock 13 -is comprised of a one-piece -spring steel such-that the forces developed-upon the lock 13 'by virtue of 'its locking function against the abutment 14 are directed in a sense to maintain the tongues 23 in fully scated relation upon the flange 11F. rhus, the Ylock may be vdisengaged only by an appropriate release motion.
