INVENTOR. J'omv 1P foasreon M) v Jrroaw United States Patent Ofiice 3,372,522 Patented Mar. 12, 1968 3,372,522 DETACHABLE GRILL ASSEMBLY FOR WINDOW SASH John P. Engstrom, Minneapolis, Minn, assignor to JJJ.

Specialty Co., Minneapolis, Minn., a corporation of Minnesota Filed Aug. 11, 1966, Ser. No. 571,875 1 Claim. (Cl. 52-456) ABSTRACT OF THE DISCLOSURE A detachable sash grill assembly comprising a springlike angled clip having a self holding portion inserted into an end of a grill bar and a toothed portion biting into an adjacent sash portion.

This invention relates to a grill structure for a window sash. More specifically, this invention relates to a grill assembly comprising portions adapted to be readily assembled to form a grill structure for detachable installation onto a window sash.

Grill structures are desirable as a decorative addition to a window sash. Detachable grill structures of various designs permit a dealer to carry a standard or basic type of window sash in inventory, and to such a sash there may be added a grill structure of whatever available design that may be desired. This permits a much smaller and less varied inventory of sash to be carried in stock than would otherwise be required if grill structures of various designs were permanently attached to the sash.

It is an object of this invention to provide a grill structure which is separate from a window sash and which is adapted for installation thereon.

It is another object of this invention to provide a grill structure in a disassembled condition adapted for ready assembly by hand and adapted for installation onto a window sash by hand.

It is also an object of this invention to provide a grill structure adapted for ready assembly by hand and including resilient retractable holding means for rem'ovably gripping the framework of a window sash.

These and other objects and advantages of the invention will be set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:

FIG. 1 is a view in front elevation showing the invention herein in operating position;

FIG. 2 is a view in elevation showing the assembled device comprising the invention herein;

FIG. 3 is a view similar to that in FIG. 2 showing the device in exploded position on an enlarged scale with portions thereof broken away and partially in section;

FIG. 4 is a broken view in vertical section on an enlarged scale taken on line 44 of FIG. 1 as indicated;

FIG. 5 is a composite view showing a detail of structure broken away on an enlarged scale in side elevation and in end elevation;

FIG. 6 is a view in perspective on an enlarged scale showing a detail of the structure; and

FIG. 7 is a view in elevation on an enlarged scale showing another detail of the structure.

Referring to the drawings, a window sash 10 of conventional design is shown comprising a top rail 11, a bottom rail 12, side rails 13 and 14, and a window pane 15.

Mounted onto said sash, as shown in FIG. 1, is a grill structure 20. It will be understood that said gril-l structure may be formed to be variously designed. Shown here is a grill structure of a basic design. Said grill structure comprises a unitary bar 22 forming a transom and a vertical cross bar 24 which is formed to be split transversely and to comprise portions 25 and 26, which portions are commonly known in the trade as mounts.

The bar 22 is provided with an aperture 23 centrally transversely therethrough, as shown in FIG. 3. The bar portion 26 is apertured axially at one end as indicated by the character 26b to receive a portion of a joiner pin 27 press fit therein. Said joiner pin is formed to have circularly grooved end portions forming rearward projecting teeth 27a, as shown in FIG. 7. Said joiner pin is thus formed at each end with only one end portion thereof being illustrated, and when press fit into an accommodating aperture this construction of the joiner pin makes a strong connection. Said joiner pin is thus secured to the bar portion 26. Said aperture 2612 will be somewhat smaller in diameter than the grooved portion of said joiner pin.

In assembling the grill structure, the portion of the joiner pin 27 projecting from the bar portion 26 will be passed through the aperture 23 of the bar 22 and into the bore 21 extending inwardly of the adjacent end portion of the bar 25, as indicated in FIG. 3. In this manner the bars 22 and 24 are assembled into a cross bar re- 'lationship and are held together by said joiner pin 27 in an integral relationship. The rearward projecting teeth at the ends of the joiner pin make such a strong connection that the bar portions 25 and 26 may be regarded as being permanently connected.

The adjacent ends 25a and 26a of the bar portions 25 and 26 will have a configuration adapted to correspond with the configuration of the respective engaged surface portions of said bar 22.

Formed into the free or remote ends of said bars 22 and 24 are transverse kerfs or slits. Only one such slit designated by the character 28 is here described and this is representative of the other slits. Said slit 28 is here shown as an upwardly angled open-ended slit. Said slit is preferably angled upwardly to provide a stronger construction.

Disposed into said slits are holding members or clips of which a representative clip is indicated by the character 29. Said clip as here shown comprises a plate member formed of a suitable resilient sheet metal having angled wall portions 30 and 31. Said wall portion 31 has a tongue portion 32 struck therefrom projecting to one side thereof.

Said tongue is shown as having a substantially rectangular projecting portion with the free end corner portions being angled as at 32a to provide tooth portions to bite into an adjacent side of a slit. Said wall 31 will be disposed into a slit 28, as shown in FIG. 5.

The other wall 30 of said clip has a saw-toothed free end portion 33 with said teeth being angled somewhat downwardly with reference to the normal position of said clip, as shown in FIG. 5. Thus when said clip is in operating position as shown in FIG. 4, said teeth 32a will bite into the edge portion of the adjacent engaged rail portion of the window sash.

Upon being assembled as above described, said grill structure will be positioned as shown in FIG. 1. It will be understood that the bars 22 and 24 will be of a length to span the window pane of the sash upon which the grill structure will be installed. The lower portions of the ends of the bars 22 and 24 will be somewhat undersized, as indicated by the character 22b with reference to the bar 22. The undercutting of the lower portions of the ends of the bars provide a small space for movement of said clip 29 whereby the teeth 32a bite into the adjacent rail portion of the sash. For removal of the grill structure, a narrow blade as of a pen knife may be inserted between the edge of the rail and the wall 30 of the clip to spring or press the teeth 33 away from the adjacent rail portion and out of engagement therewith whereby the bar portion of the grill structure may be raised. With a second clip being thus disengaged from a second rail portion, the grill structure may be readily removed from the window sash. To install the grill structure, it is very simply pressed downwardly into position and the toothed portions of the clips bite into the adjacent rail portions of the sash. With the clips 29 in operating position, the grill structure is strongly secured to the window sash.

Thus it is seen that I have provided a simply constructed detachable grill structure for a window sash which may be disassembled into a small package and which may be readily assembled by hand and installed in operating position.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention which, generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claim.

What is claimed is:

1. A detachable grill assembly for a window sash having in combination,

a pair of elongated bars secured together in a crossed relation and being of respective lengths to extend between and abut opposing rails of said sash,

the end portions of said bars respectively having inwardly extending slits,

holding means for said end portions each comprising a resilient plate member forming a pair of angled walls,

one of said walls having a tongue struck therefrom projecting outwardly of the plane thereof, the free end corner portions of said tongue angled out of the plane thereof, said Wall being disposed Within one of said slitted end portions of said bars self held therein by said tongue, and

the other of said walls having a toothed end portion angled out of the plane of its wall in a direction away from said first mentioned wall, said toothed end portion biting into the sash portion adjacent said slitted end portion of said bar for engagement therewith.
