4 Claims. (CI. 49-61) ABSTRACT OF THE DISCLOSURE The present invention relates to window assemblies, especially to window assemblies adapted to carry a storm sash removably thereon by a plurality of latches associated with the Window assembly.
The general object of the present invention is to provide a novel and improved window assembly characterized by the removable positioning of a storm sash in the window assembly and by the ready and convenient accessible control of the engagement and removal of the storm sash with relation to the primary window.
Another object of the invention is to provide a storm sash with a plurality of latches having control arms and locking arms thereon wherein the locking arms of the latches can readily be engaged with a sash rail of the prime window for removable sealed engagement of the storm sash with the prime window.
A further object of the invention is to provide a novel and improved latch means particularly suited for securing a storm sash to a carrier member in any suitable type of a window, door, or other assembly.
The foregoing and other objects of the invention will be made more apparent as the specification proceeds.
Attention now is particularly directed to the accompanying drawings wherein:
FIG. 1 is an elevation of a window ing the principles of the invention; 7
FIG. 2 is an enlarged fragmentary perspective View, partially shown in vertical section, of a portion of the window of FIG. 1;
FIG. 3 is an enlarged fragmentary vertical section showing the engagement of the locking arm of the latch With the primary window sash; and
FIG. 4 is a top plan view of a latch member embodying the principles of the invention. a
The present invention, generally speaking, relates to a storm window assembly, or the like, wherein a prime Window sash is present and it usually has four sash rails forming a sash enclosure with sash positioning means extending inwardly of the plane of the sash on, usually, the outer portion of the sash rails, at least two of the sash rails having locking slots formed therein, and a second sash is provided of a size to be received in the sash rails enclosure, the invention particularly comprising the improvement of a plurality of sash latches being present, each having an elongated control arm and a short locking arm thereon, which locking arm is spaced axially from the control arm in each latch, and means are present that pivotally secure the latches to the second sash for movement of the locking arms into engagement with the slots to force the second sash into engagement assembly embodywith the sash positioning means of the sash rails and provide a removable assembly of the second sash on the prime window sash.
With reference to the details of the structure shown in the drawings, FIG. 1 shows a window assembly as indicated as a whole by the numeral 1. It will be realized that this window may be used in a window frame, a door, or any other desired opening, but the invention particularly will be described and shown with relation to a window assembly that usually would be mounted as a double hung Window adapted for sliding vertical or horizontal movement, as desired. The window assembly 1 includes a primary window 2 that normally has four sash rails 3, 4, 5 and 6 provided therein and suitably secured together to provide a sash enclosure for the prime window 2. A window pane 7 normally is carried by the prime window 2 as by suitable sash positioning means 8 that are carried by, or formed as a suitable unit with, the sash rails and extend inwardly of the prime window 2. These sash engaging means may comprise a pair of spaced flanges and with such flanges and the remainder of the sash rails as shown in FIG. 2 being formed as unitary metal extrusions from any suit-able material. The window pane 7 can be secured within the sash engaging means 8 by any conventional member, such as a plastic sealing strip 9, which is forced into engagement with the sash engaging means to position the window pane 7.
FIG. 2 of the drawings best shows that the sash rail 4, which is only exemplary of all the sash rails and how they can be constructed, has the sash positioning means 8 provided on one lateral portion thereof, preferably the outer portion of the sash rail. The sash rail 4 is also shown as including a substantially rectangular hollow section 10 as a portion thereof, which sash section 10 is of greater depth than the sash positioning means 8 as provided thereon whereby a second sash, such as a storm sash indicated as a whole by the numeral 11, can be carried by the prime window 2. This storm sash 11 is of such size .that it can be received within the confines of the sections 10 provided on the sash rails of the prime window 2. Such storm sash 11 is adapted to be brought into resilient sealed engagement with an inwardly extending portion of the sash positioning means 8, as by abutting against a resilient sealing strip 12 provided between one flange of the sash positioning means 8 and an adjacent wall or sash rail of the storm sash 11. At such time, the outer surface of the storm sash 11 is preferably in substantial vertical alignment with the inner margins of the sash rails of the prime window 2.
For the purpose hereinafter to be described in more detail, at least two of the sash rails 3 through 6 have one or more locking slots 13 provided in the inner wall of the section 10 of the sash rail.
As an important feature of the invention, a plurality of locking latches 14 are pivotally carried by the storm sash 11. Each of these latches 14 has an elongated control arm 15 and a short locking arm 16 formed thereon. Usually the control arms 15 each have a flange 17 formed thereon and normally the locking arms 16 are axially spaced from the locking arms 16 whereby the latches will have the control arms 15 positioned, usually, on the inner surface of the sash rails of the storm sash 11 but with the locking arms 15 being received within recesses 18 provided in a sash rail, or equivalent 19 of the storm sash 11. These latches 14 are positioned by suitable members such as rivet-s, pins, or the like 20 that are secured to the sash rail 19 or other rail of the storm sash whereby the latch is positioned for pivotal movement from the dotted inoperative position shown in FIG. 3 over to an operative position as shown in solid lines in FIG. 3 when the locking arm 16 extends into the slot 13 to engage an associated portion of the section 10 of the sash rail of the prime window. To facilitate engagement of the locking arm 16 with the wall or other adjacent portions of the sash rail 3, for example, a cam section 21 usually is provided on the corner area of this locking arm 16 which first engages the sash rail 3 as the latch 14 is swung to a locking position.
It will be realized that the latches 14 are so positioned on the storm sash 11 as to be brought readily into perative engagement with the slots 13 in the prime window sash rails and that the thickness of the storm sash 11 is such that the inner margins of the storm sash will be brought into compressive engagement with the sealing strips 12 to urge them against the sash engaging positioning means 8 on the prime window by moving the latches into operative positions.
By the use of, preferably, two or more of these latches 14 in the window assembly 1, the storm sash 11 can be positively but yet removably carried in the window assembly so that the components of the window assembly can readily be reached for cleaning action or for repair or replacement purposes, as desired. The latches and/or the locking arms thereof usually frictionally engage associated means to retain any given position. The latches are made of suitable metal construction and will provide a long service life with a minimum maintenance thereon. Hence, it is believed that the objects of the invention have been achieved.
While one complete embodiment of the invention has been disclosed herein, it will be appreciated that modification of this particular embodiment of the invention may be resorted to without departing from the scope of the invention as defined in the appended claims.
