CASEMENT WINDOW LOCK Samuel C. Reynaud, Detroit, Mich. Application October 30, 1947, Serial No. '782,980V
Another object is to provide a easement window lock which can be operated through the `slats of a Venetian blind without the necessity of raising the blind, merely by inserting the nger between the slats of the blind and pulling the handle outward to lock the window or pushing it inward to unlock the window.
Another object is to provide a easement window lock which is `equally well adapted to the locking of easement windows which swing either to the right or to the left, without requiring right-handed or left-handed locks. 11 Another object is to provide a easement window lock of simple and easily manufactured `form which can be made at low cost and sold at a low price, yet which has few parts to get out of order.
In the drawings:
Figure 1 is an elevation of a easement window, viewed from inside the building, showing a casement window lock according to a preferred form of the invention;
Figure 2 is a horizontal section taken along the line 2-2 in Figure l, showing the lock in its unlocked position;
Figure 3 is an enlarged detail horizontal section similar to the right-hand end of Figure 2 but taken along the line 3--3 in Figure 1 and showing the lock in its locked position;
Figure 4 is an approximately transverse vertical section taken along the line 4-4 in Figure 3; and
Figure 5 is a vertical section taken along the line 5--5 in Figure 3 at right angles to Figure 4.
Referring to the drawings in detail, Figure l shows a easement window generally designated Il) consisting generally of a window frame II with a easement window I2 hinged thereto and locked in position by a lock I3, according to a preferred form of the invention. The frame II is inserted in an opening I4 in the building wall I5 (Figure 2) and is of approximately rectangular form and of roughly Z-shaped cross-section. Mounted on a vertical edge of the frame II such as by the fasteners I6 is the inner arm Il of a hinge bracket generally designated I8, the outer arm I9 of which is hinged to the inner arm I1 `bv the hinge pins 20. The outer 1 Claim. (Cl. 292-202) v 2 j arm ,I9 is also flanged, and is secured as by the fasteners 2l to the window frame 22.
The window frame 22 is likewise of roughly Z-shaped cross section and has mounted therein one or more panesv23 of glass or other transparent or translucent material, a conventional, mounting medium 24 being employed. The sta-v tionary frame I I and the movable window frame I2 is assembly form a chamber 2 5 of rectangular cross-section lying between the flanges 26 and 2'I and connecting web 28 of the stationary frame II (Figure 3) on the one sidev and between the anges 29 and 30 and their connecting web 3| on the opposite side. The flanges 30 and 29 (Figure 3) overlap the flanges 26 and 2l which they respectively engage.
The movable window frame I2 is drilled and threaded as at 32 to receive a pair of screws 33 which are inserted through vertically elongated holes 34 (Figure 4) in the base plate 35 of a keeper 3G of resilient material such as spring steel. The keeper 36 has a tongue 3l in the form of an arm projecting transversely from the base plate 35. The tongue 3l` is bent intermediately and at its junction with the base plate 35 to form a hump 38 at the mid-portion thereof.
Engageable with the tongue 3l of the keeper 36 is a swinging latch 39 of approximately bellcrank form having inner and outer arms 40 and 4I with upper and lower connecting flanges 42 which are bored as at 43 for the passage of a pivot pin 44. The opposite ends of the pivot pin 44 also pass through holes 45 in the upper and lower arms 46 of an approximately U-shaped bracket 4'I having angled attachment flanges 48 projecting from the arms 46. The latter are drilled for the passage of screws 41a which are threaded into threaded holes 48a in the stationary window frame Il (Figure 4). The arm 40 is provided with an elongated aperture 49 (Figure 4) near its outer end, the latter being 4bent as at 50 in order to prevent it from contacting the base plate 35 prematurely. The ilange 2'I of the stationary frame II is provided with an elongated Vertical aperture 5I for the passage of the arm 49 of the swinging latch 39. The arm 4I of the latter is provided with an outwardly curved end portion 52 which serves as a handle for engagement by the end of the users lingers.
In the operation of the invention, let it be assumed that the parts are in the positions of Figures 1 and 2, with the window I2 closed but not yet locked. To lock the window, the operator hooks the end of his finger over the concave side of the curved portion 52 of the latch 39 and pulls it outward toward him into the position shown in Figures 3 and 4. When this is done, the arm 40 swings toward the keeper 36 so that the tongue 31' enters the aperture 49 and the Outeiedge of the latter slides over the hump 38. The tongue 31 yields while this is occurring, springing inward to permit the end portion 50 of the arm 40 to pass over the hump 38. The latter then prevents the accidental swinging of the latch 39 into its unlocked position and the lock I3 is thus firmly but yieldingly held in its locked position (Figures 3 and 4).
To unlock the lock I3, the operator pushes against the convex portion of the curved end l52 of the latch arm 4|, pushingit toward the window I2 from the position of Figure 3 to that of Figure 2. When this occurs, the arm 40 swings to the right around the pivot pin 44, causing the end portion 5i) thereof to snap over the hump 38 of the tongue 37 and into the position shown in Figure 2. The window I 2 may then be opened in the usual way, swinging outward around its hinge pins 2l).
What I claim is:
A latch structure for locking the tongued keeper -of a swinging easement window to its frame, comprising a bracket attachable to the frame,
CFI
and a latch lever of bell-crank form pivoted to said bracket, said latch lever having a longitudinally elongated outer arm and having an inner arm bent substantially at right angles to said outer arm, said inner arm adjacent its free end being provided with an aperture extending therethrough and said free end beyond the aperture being bent to provide a laterally extendingl portion, the tip of said laterally extending portion being offset relatively to the remainder of said inner arm.
