United States Patent 3,208,782 WEATHERPROQF SLIDING WINDOWS Lawrence Zeller, RR. 3, Harmon, Ontario, Canada Filed May 31, 1962, Ser. No. 199,054 1 Claim. (Cl. 292-2515) The present invention relates to a holder and lock for sashless windows and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally the invention comprises novel devices for holding and locking windows of the sashless type where panels of plate glass are mounted to slide past each other in a frame and without a sash encasing the glass panels themselves. The invention contemplates the use of an upper and one or more intermediate holding devices of novel structure which utilize permanent magnets and lower locking and holding device likewise using a permanent magnet and having a novel locking structure incorporated therewith. The invention permits the secure holding of horizontally sliding panels in their closed position and also permits the secure locking of such windows when desired.

It is accordingly an object of the invention to provide a novel holding device and lock for sashless windows.

Still another object of the invention is to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and etiicient in use.

Another object of the invention is to provide, in a device of the character set forth, novel locking means forming a part of the invention.

Still another object of the invention is to provide, in a device of the character set forth, novel means for mounting the component parts thereof upon sashless windows.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

FIGURE 1 is a vertical sectional view of a pair of cooperating sashless windows illustrating the devices of ,the present invention mounted thereon,

FIGURE 2 is an enlarged vertical sectional view of a holding device forming a part of the present invention,

FIGURE 3 is an elevational view of a closure disc utilized in the device of FIGURE 2,

FIGURE 4 is an enlarged fragmentary vertical sectional view, partly in elevation, of a holding and locking device forming a part of the invention,

FIGURE 5 is an elevational view of a closure disc utilized in the device illustrated in FIGURE 4,

FIGURE 6 is a fragmentary sectional view, partly in elevation, of the device illustrated in FIGURE 4 but taken at right angles thereto, and

FIGURE 7 is a sectional view taken substantially along line 7-7 of FIGURE 6.

Referring more particularly to the drawing, there is shown therein a pair of horizontally slidable sashless windows 10 and 11 and in the vertical cross sectional view shown in FIGURE 1, there is generally indicated at 12, 13 and 14, respectively, an upper holder, an intermediate holder and a combined holder and lock.

Extending through a suitable opening in the window 11 is a cylindrical housing 15 of stainless metal or suitable plastic material encasing a permanent magnet 16. The window 11 is countersunk, as indicated at 17, to accommodate an annular flange of the casing 15 and it will be seen by reference to FIGURE 2 that the outer face of the flange 18 and the outer face of the magnet 16 are flush with the adjacent face of the window 11. The casing 15 is held fixed in position by means of a collar 19 aflixed to the casing 15 by means of pins 20 or the like.

3,208,782 Patented Sept. 28, 1965 ice A steel disc 21 is mounted in a countersunk opening 22 in the inner face of the window 10 and is centrally provided with an integrally formed stud 23 which extends through an opening 24 in the window 10 and has threaded thereon at its outer end a locking nut 25. It will be seen that the outer face of the disc 21 lies flush with the inner face of the window 10.

The combined holder and lock 14 is illustrated in greater detail in FIGURES 4 to 7, inclusive, and consists of a cylindrical housing 26 having centrally and longitudinally mounted therein a tubular member 27. The inner end of the housing 26 is provided with an annular flange 28 suitably countersunk in the outer face of the window 11 and a permanent magnet 29 of annular form surrounds the tubular member 27 and is encompassed by the easing 26.

A collar 30 secured by pins 31 or the like to the casing 26 acts to rigidly hold the member 14 in position in the window 11 and it will be apparent that the outer faces of the flange 28 and magnet 29 lie flush with the outer face of the window 11.

Countersunk in the window 10 is a disc 32 of steel or other magnetic material having a stud 33 extending through an opening 34 in the window 10 and having threadably mounted thereon at the free end thereof a locking nut 35. A recess 36 extends centrally through the plate 32 and into the stud 33.

Adjacent the inner end of the tube there is provided a pair of bayonet slots 37 and, inwardly of the slots 37 there is provided a pair of diametrically opposed inwardly directed arms 33.

A lock shaft 39 having an operating handle 40 at its outer end centrally extends through the outer end of the casing 26 and through the tube 27 and has fixed thereto at its inner end a collar 41 from which extends a pair of diametrically opposed pins 42 each receivable in one of the bayonet slots 37. A compression spring 43 surrounds the shaft 39 and bears at one end against the arms 38 and at its other end against a pin 44 affixed to and extending through the shaft 39 immediately inwardly of the outer end wall of the cylinder 26.

In operation, it will be apparent that when the windows 11 and 10 are brought to closed position, the upper and intermediate holder members 12 and 13 will register with their respective plates 21 and that the magnets 16 will coact with the plates 21 to hold the window in such closed position. This is also true, of course, with respect to the plate 32 and magnet 29 in the combined locking and holding device 14. When, however, it is desired to lock the windows 10 and 11 in their closed position, it is only necessary to grasp the handle 40 and move the shaft 39 thereby until the free end thereof enters the recess 36 in the stud 33, thereafter turning the handle 40 to move the pins 42 into locking engagement in the bayonet slots 37. To unlock the windows 10 and 11, the pins 42 are disengaged from the bayonet slots 37 by twisting the shaft by means of the handle 40 in the reverse direction thus freeing the pins from engagement with the circumferential extending portions of the bayonet slots to the longitudinally extending arms thereof thus permitting the compression spring 43 to move the shaft 39 out of engagement with the recess 36 and the stud 33.

It will be apparent that in the case of large windows one or more intermediate holder members 13 may be employed whereas in a case of extremely small windows, the intermediate holder members 13 may not be necessary.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A weatherproof holder for a pair of co-operating sliding sashless windows having opposed surfaces facing one another in closely overlying relation, and comprising; a cylindrical casing mountable in one side Window and of a length greater than the thickness of said window; one closed and one open end on said casing; an annular retaining flange of greater diameter than said casing extending outwardly therefrom in a plane substantially normal to the axis thereof around said open end for retaining said casing in position in said window with said flange flush with an opposed surface thereof, said flange being of a thickness substantially less than the thickness of said window; an annular collar member slidably mountable around said casing for abutting against the other suurface of said window and retaining said casing in position therein; fastening means in said collar member for attachment thereof to said casing; a permanent magnet mounted in said casing; one end of said magnet exposed at said open end of said casing and lying in a common plane with said annular flange and forming a flush surface therewith; a circular plate of permeable material of a diameter substantially equal to the diameter of said annular flange, mountable in the opposed surface of the other said window and of a thickness substantially less than the thickness thereof and having a contact face on one side thereof; a threaded stud of reduced diameter in relation to said plate extending from the other side thereof and of a length greater than the thickness of said window; threaded means for engaging the free end of said stud.
