Jan. 16, 1951 WINDOW LOCK Filed Marh so, 1948 Z w; MMM W,
*rainwater :or the like.
Patented Jan. 16, l95l NITED PATENT if OFFICE WINDOW LOCK VJohn 'SchurmanfDetroia Mich.,1ass'gnor to Hig- "gins "Resources, Inc., New OrleansJia.,ia corpolaation Lof `Louisiana .AppIcatiOnMarhSD, 194.8, VSerial No. 18,031 c 'This invention relates to "a lock and, `more particularly, to a `window lock rfor a pivotally mounted window.
An outstanding disadvantage arising `fromthe operation of common types of window locks "is that, 'after unlocking, it is often lnecessary `to exert vexcessive `manual eiforttopush thewindow sash away from the framedue :to the tendency of these'parts to stick togethenparticularly when the sash becomes vfrozen vto vthe frame 'by frozen IFurthermore such locks are oftentimes not entirely burglar-proof.
An object of the present inventionis 'to overcome the 'above-mentioned `disadvantages -and to provide a novel lock particularly useful for 'a pivotallymounted window, which lo'ckfis'so constructed that the unlocking movement of rthe handle 'will positively force the `window away from the frame, so as to break any seal formed Aby ice or the like tending Ato hold these` parts together. g
Another object of the invention is to vprovide a window lock mechanism which is relatively simple in construction, inexpensive to manufacture and devoid of springs and other such .parts normally requiring frequent replacement.
A further object of `the inventionis .tov provide a reliable window lock which willpositivelylock together a window sash andframe in a manner so as to be truly burglar proof.
Broadly stated, the window 'lock embodying the present .invention comprises'a hook (or catch) adapted to be secured to a pivotally mounted window sash .and a Ela'tch `mechanism ,adapted tobesecured vto a window framawhich Klatch ygether with fthe accompanyingdrawings wherein:
Figure l a longitudinal lcross-sectional 4view of a loci:I embodying the'present invention whereinthe `partsare shown in vthe fully lockedposition;
fFigure v2 is .a cross-sectional viewtsimilar `to Figure 1, ,except that the parts are shown .in-.an intermediate positiontobetter illustrate how .the latch pushes. against the hook;
"Figure 3 isa cross-sectional view similar to 6 Claims. (Cl. 292-113) F'igures'l vand 2, except that the parts are shown in the jfully unlocked position; and,
"Figure 4 isa cross-sectional view taken on line llof Figure l.
:Referring more particularly to the drawings, numeral `'l denotes a hook, or catch, which is adapted to tbe attached to a pivotally mounted window sash '2, only a 'fragment of which is shown, by any well-known fastening means, such as screws, bolts, etc. Numeral 3 generally denotes alatch mechanism enclosed in a housing adapted to be -fastened to `awindow `frame (not shown) 'formed of half portions "3a fand f3?) which are sweated or otherwise integrally secured together to form the'housing. The housing halves are each 'provided with a cavity to denne a space in vwhich the internal parts of the latch mechanism may move. integrally formed on the housing r'l'lalves lare two inwardly projecting guide portions 3c and i3d ywhich are slightly offset with respect to each other, that is, they are not in exactconfronting or opposing relationship. An operating handle or lever il is pivotally mounted on the housing 3 by Vmeans of a pin 5. A cam or latch is pivotally mounted, at one end, on handle All 'by means of a pin 1. The free end Ba of latch B is hook-shaped and is adapted to behookedin locking engagement with hook l.
' Latch t has, Vat one side thereof, a substantially straightrportion 6b which is adapted to slide against guide `portion 3c to guide the latch s0 as to'initiallymove'in a substantially rectilinear direction 'from the position shown in Figure 1 to'thatshown in Figure 2. The other side of latch or catch A5 has a somewhat straight portion 6c and '.anoutwardly extending cam `portion 6d adapted to slide on guide portion 3d.
vThe operation ofthe loci: mechanism is as follows:
Assume that thelock is in the position shown in Figure l, that is, in the fully locked position. The operator turns handle 4il clockwise about pin 5 as a pivot. The'latch will be moved towards the right as viewed in Figure l `in a substantially horizontal direction during the initial vrotation ofhandle .4 because of the engagement of the straight portion 6b :of the "latch with guide portion "3c in the course of this movement. The hook-shaped end a "thereof abuts against the base ofhook l. Therefore, upon continued rotan tion of vhandle li, latch E is ,positively pushed against the'base of `the hook `as shown in Figure 2 thereby forcing the hook away from the latching mechanism and breaking any .seal that might have beenmrmed vbetween the window sash and frame. Upon further rotation of handle 4, portion 6c and then portion 6d slide in succession against guide portion 3d, the latter portion causing rocking of said latch so as to lift the hookshaped end away from said hook so as to clear it as shown in Figure 3. This rocking or turning of the latch is possible by virtue of the offset relationship of the inwardly extending guide portions 3c and 3d and the shape of latch 6. Upon rocking of the latch, the upper projection 3c cooperates with a downwardly curved portion Bf of the cam to allow turning of the latch about pin 1 as a pivot. The window sash may therefore be pushed away from the latch mechanism such as by a separate crank or handle (not shown).
Of course, when it is desired to lock the win-V dow, the reverse process takes place. That is, the hook is moved to the position shown in Figure 3 and the handle 4 is turned counterclockwise to move the latch 6 to the position shown in Figure 2 and upon further movement to the position shown in Figure 1, thereby hooking and drawing in hook l against a seat portion in the housing, which seat portion conforms to the shape of the lower surface of the hook, s as to rmly lock the hook in place and prevent rattling or vibration of the Window. It will be noted that when the parts are in the locked position shown in Figure 1, pin 1 is moved past dead-center with respect to pin to prevent the possibility of unlocking of the locking mechanism by the mere pulling of the window which carries hook I, therefore making the lock burglar-proof.
Thus it will be seen that I have provided an eicient, relatively simple and reliable lock which is not only burglar-proof but which is so constructed as to break the seal between the locked parts, such as a window sash and window frame, to insure and facilitate separation of such parts. While, for purposes of illustration, the hook has been described as being secured to a window sash, it will be readily apparent that it may, instead, be secured to a screen, door, or other part which is relatively movable with respect to a stationary frame to which the latch mechanism is secured. For example, the latch mechanism may be extended through a window screen fastened to the window frame and the hook may be secured to an outside pivotally mounted window swingable away from the locking mechanism. Furthermore, the locking elements may be reversed, that is, hook l may be secured to the xed member and the latch mechanism secured to the movable member. Similarly, other modifications of the invention will be readily suggested to those skilled in the art after having had the benet of the teachings of the present disclosure.
While I have illustrated and described one specific embodiment of my invention, it will be understood that various changes and modifications may be made Within the contemplation oi' my invention and under the scope of the following claims.
I claim:
