Description

A. SPRUNG Sept. 6, 1966 COMBINED GASEMENT WINDOW LATCH WITH LOCKING MEANS Filed June 2. 1965 United States Patent 3,270,536 COMBINED CASEMENT WINDOW LATCH WITH LOCKING MEANS Abraham Sprung, Flushing, N.Y. (2200 Central Road, Fort Lee, NJ. 07024) Filed June 2, 1965, Ser. No. 460,725 8 Claims. (Cl. 7089) This invention relates generally to latches for casement windows in which the bracket member of the latch is adapted to include a member of the locking means. More specifically, this invention combines the operating handle member and the bracket member of the latch into one unit with the locking means. This unified latching-lock device can be used to replace the standard latching means without drilling additional holes in the frame of the jamb usually required for locking attachments.
This invention, as disclosed herein, will also provide for the locking member of the latch to removably engage one end of a chain to the jamb with the other end fixed to the window frame. In this manner this invention can be used either to lock the window directly to the jamb or indirectly wherein it will allow for a small space between the window and the jamb to be used for ventilation through the partially opened window and still be in a locked position. This invention primarily will deter an unauthorized person from unlocking the latch, thus gaining entrance through the window.
Another object of this invention is to provide a latch having one of its members as a locking means and which is inexpensive in construction, easy to install and operate.
Other and more limited objects of the invention will be apparent from the following specifications and the accompanying drawings forming a part thereof wherein:
FIG. 1 is a front elevation of the invention showing the casement window latch wherein the bracket member includes a locking means member.
FIG. 2 is a vertical section taken on the line 2-2 of FIG. 1;
FIG. 3 is a vertical section taken on the line 3-3 of FIG. 2 showing the locking means in the lock position;
FIG. 4 is a detail vertical section showing the locking member in engagement with the chain locking member in a closed position;
FIG. 5 is a perspective view showing bracket member of latch, locking means, and chain member holding window in a partially open position.
Additional features and adaptations of this invention will be illustrated herein as applicable to a swinging casement window or door required to be held and locked in either a closed or partially closed position with the use of a standard latch comprising an outwardly swinging handle hingedly operating between two ears forming a member of the latch bracket. The handle operates a latching finger which is part of and located on the upper end of the handle and serves to latch and unlatch the window. The two ears which are spaced apart include the hinge of the operating handle which also include two space openings through which the locking element of locking means is adapted to be inserted. This locking element comprises a slidable bolt of a standard lock which may be either a plunger type or padlock type. The inseration of this bolt through the opening of the ears will prevent any vertical operation of the handle or latching finger. The unlocking of the locking element or bolt is performed by a key.
The same sliding bolt of the lock can be used for engaging one end of a member formed with a ring and the other end fixedly attached to the window frame. The ring is to be inserted between the ears and aligned with 3,270,536 Patented Sept. 6, 1966 the openings of said ears to allow the bolt to slide through.
Referring to the drawing the numeral 10 shows a section of the window jamb and 11 is a section of the casement window sash of the window 12, adapted to contact jamb 10 when window 12 is closed, The window 12 comprises both the sash 11 and glass pane 13. A latching means 14 and locking means 23 are adapted to hold and lock casement window 12 against jamb 10. The latch 14 comprises an operating handle 19 hingedly swinging between two ears at the hinge pin 15. The ears 16a and 1612 which are spaced apart at 16c and located perpen dicularly to jamb 10 are supported by bracket 17 which is screwed to jamb 10 at 18 and 18. The operating handle 19 is formed at its upper and inner end with an upwardly curved latching finger 20 and hinged around the hinge pin 15 so that a downward movement of the handle 19 will operate latching finger 20 upward and inward, engaging striker plates 22 of sash 11 on window 12, thereby latching said window to jamb 10. To unlatch window 12 for opening, the latching finger 20 is disengaged from sash 11 by operating handle 19 upward and around hinge pin 15. Latching finger 20 is formed at its lower end and located below hinge 15 with a generally U-shaped portion 20' at the point where the latching finger meets the upper inside portion of handle 19.
To lock the latch 14 it is necessary to slide a horizontal bolt 26 through the openings 16a and 16b and the generally U-shaped portion of the handle 20'. This will prevent the handle 19 from pivoting around hinge pin 15. The bolt 26 can be inserted through openings in the ears by means of a plunger 24 of lock 23 or any standard padlock. The lock 23 which can be a standard sliding door key-operated cylinder lock consisting of a casing or a cylindrical housing 25 and a plunger or cylinder insert 24, is so arranged that it can be pushed inwardly and fixedly held by a standard retaining means of the plunger 24 of lock 23 or the padlock. In order to unlock the latch 14 as shown in FIG. 1 it is necessary to turn key 27 which will release the retaining means thereby allowing the bolt to return in a disengaged position. The lock can be operated through casing 25 attached to either the right ear 16a or to the left ear 16b. It is to be noted that the casing 25 of lock 23 which operates the bolt through the ears and generally U-shaped portion 20' can be either a fixed part of latch bracket 17 or a detached lock as in a padlock.
FIG. 2 distinctly shows how the slide bolt 26 will prevent the swinging motion of operating handle 19 and latching finger 20 around the hinge pin 15. FIG. 3 shows how slide bolt 26 engages through both ears 16a and 16b and 20 when latch 14 is in a locked position.
Another method of locking the window sash 11 to jamb 10 is shown in FIG. 4 and FIG. 5 wherein an intermediate space member 28, having one end attached to the window sash 11 at point 30 and the other end provided with a ring 29 adapted to be inserted upward and inward in space 16c at the U-shaped portion 20 between ears 16a and 16b through the aligned openings 16a and 16b so that the dead bolt 26 can be pushed through the openings 16a and 16b and the U-shaped portion 20' engaging the ring 29 of the space member. This operation will hold and lock space member 28 so that window 12 will be locked in a partially open fixed position as shown in FIG. 5.
Bracket 17 including the latch 14 and lock 23 is designed to conform in all respects to a standard latch bracket including the location of holes for screws 18 and 18'. This will allow for an easy replacement of this invention for the standard latch on standard casement windows.
From the foregoing it will be apparent to those skilled in this art that I have provided a very simple and efficient mechanism for accomplishing the objects of my invention.
It is to be understood that I am not restricted to the specific construction shown and described herein, as various modifications may be made thereto within the spirit of the invention.
