2,809,728 FRAMING CHANNEL STRUCTURES Harold G. Olson, Old Greenwich, Conn., assignor to-The Bailey Company, Inc, Amesbury, Mass, a corporation of Massachusetts Application December S, 1955, Serial No. 551,848

6 Claims- (Cl. 189-76) This invention relates to improvements in channel structures and more particularly to metallic channel structures for engaging around edge margins of sheet elements which may be panes of glass, or sheets and panels of other materials, which are to be mounted within a metallic frame for protectively supporting the sheet element as a window or panel in a building or for serving in the nature of a shipping crate, or the like, to protectively enclose the edge margins of one or more glass panes, panels, or the like. The invention provides an improved channel structure, for the mentioned general purposes, wherein channels of metal and of resilient cushioning material are combined and utilized in a novel manner to attain novel results and effects.

The invention is herein illustrated and described as it may be embodied in a window frame which may be of the jalousie orany other type, but it should be understood that the disclosed channel structure is not limited in utility to window frames but may be employed wherever it becomes necessary or desirable to protectively enclose edge margins of sheet elements as a permanent frame for single sheet elements of glass, or the like, or as a permanent or temporary protective frame for edge margins of a single sheet element, such as a structural panel, for example, or a plurality of such panels, grouped together for shipment.

The present invention contemplates a novel channel structure fabricated from elongated framing stock of simple construction, lengths of which may be cut whenever desired into suitable sections that need only be joined at their ends to provide without more a weather-proof and non-rattling support or protector for a glass pane, a panel, or a plurality of the panes or panels grouped together, as for shipment.

An object of the present invention is to provide framing stock of the foregoing type comprising telescoped channels, the outer one being composed of a relatively stifi resilient material such as sheet metal, and an inner one being composed of a relatively soft compliant material such as rubber, the channels being permanently connected by beads in the extremities of the legs of the outer channel which tightly pinch the extremities of the legs of the inner channel.

Another object of the present invention is to provide a channel structure comprising sections of framing stock of the foregoing type which are connected at their ends by specially designed angle bars, the arms of which extend between bight portions of two telescoped channels.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the product posessing the properties, features and relation of components which are exemplified in the following detailed disclosure,

and the scope of the application of which will be indicated in the appended claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following United States Patent Patented Oct. 15, 1957 detailed description taken in connection with the accompanying drawing wherein:

Fig. 1 is a front elevation of a window embodying the present invention;

Fig. 2 is a perspective view of a fragment of the window of Fig. 1 with portion broken away, and with parts in section, the section being taken along the line 22 of Fig. l;

Fig.3 is a perspective view of one of the corner components of the window of Fig. 1; and

Fig. 4 is a side elevation of a modified wrap-form of framing channel.

Fig. 1 illustrates a jalousie window 10 removably secured within a suitable frame 11 by a series of pivotable fasteners 12. Window 10 includes a glass pane 13 and four framing sections 14 secured at their mitered ends by four corner brackets 15.

Sections 14 are shown in detail in Fig. 2 as comprising an inner channel 16, a medial channel 17 and an outer channel 18. Inner channel 16, preferably, is composed of a relatively soft compliant material, for example, a rubberlike material such as natural rubber or neoprene, a synthetic plastic material such as polyethylene or nylon or a fibrous material such as felt or asbestos. Inner channel16, which is designed to snugly engage the edges of pane 13, serves as a weather-proofing and shock absorbing seal or cushion. Medial channel 17 and outer channel 18 preferably are rolled into shape from suitable sheet metal blanks. Medial channel 17 is coextensive with inner-channel 16 so that its arms have the leverage and its bight portion'the proximity to tightly grip and effective ly support the edges of pane 13 with the inner cushioning and sealing channel 16 intervening between them. The

legs of outer channel 18 are longer than the legs of medial and inner channels 17 and'16 so that the bight portion 20 of the outer channel is spaced from

bight portions

21 and 22 of the the medial and inner channels. Bight portion 20 is provided with a reentrant step having a horizontal portion 23 and a vertical portion 24, as viewed in Fig. 2. Vertical portion 24 preferably is provided with a strip 25 of soft compliant material which may be cork or any of the materials described above in connection with inner channel 16. Strip 25 serves as a weather-proofing and shock absorbing seal between sash 10 and frame 11.

Channels 16, 17- and 18 are permanently connected to each other without additional discrete components as follows. The extremities of the legs of

channels

17 and 18 are reversely bent to provide

beads

26, 26 and 27, 27.

Associated beads

26 and 27 are shaped together to permanently interlock the outer two channels and at the same time to firmly pinch the extremities of the legs of inner channel 16. The beads additionaly serve as guides tospread the legs of the composite channel when the edgeof: a glass pane is introduced.

The ends of sections 14 are connected by angle brackets 15 that have been stamped, cast or otherwise formed into the shape shown in Fig. 3. Each bracket 15 has two

coplanar arms

30 and 31 which are provided, along their inner edges, with

ridges

32 and 33 lying in planes perpendicular to the common plane of the arms. As will be seen in Fig. 2, the thickness of

arms

30 and 31 is substantially the same as the distance between vertical portion 24 and the adjacent parallel portion of the longer leg of outer channel 18. Furthermore,

ridges

32 and 33 are spaced from the outer edges of the arms by distances which permit ridge 32 to immediately underlie horizontal portion 23 of one framing section 14, and ridge 23 to immediately underlie horizontal portion 23 of an adjacent framing section 14, when the outer edges of the arms underlie the outermost portions of

bights

20, 20 of the two sections. The arms and ridges of brackets 15 may be welded or otherwise secured to the reentrant step portions sections which when joined by brackets of the above description provide a weather-proof and non-rattling sash for a glass pane of any chosen size. However,' the cut sections may be joined together by any suitable means,

and may be produced in sizes suitable for engaging over edge margins of various sheet elements for any of a variety of purposes, such as for protecting the edges of panels and the like during handling and shipping.

In the interests of economy, it sometimes may be desirable to produce the framing sections in continuous strip form with cut-out notches suitably spaced apart so that the strip may be Wrapped around theedges of a pane or panel, or a plurality of grouped together panes or panels, and extend continuously around all four sides thereof. Fig. 4 shows such a continuous strip 14 which has been notched at predetermined spaced locations 34 where corner bends are to occur, with complementary end portions adapted to be brought together and secured at one corner of the frame. The 90 angular'notches may be cut in the channels prior to their being assembledor after assembly. Corner brackets 15, or the like, at each of three of the corners may be loosely inserted at the time of bending the frame. Each of these brackets will be retained as a corner reinforcement by the right-angularly related sides of the frame extending from that corner. The bracket 15 at the fourth corner, Where the mitre joint is to be effected, may have the opposite end portions welded or otherwise rigidly secured to it for strengthening the mitre joint. Obviously, all of the corner brackets may be welded or otherwise secured to the outer channels if this is considered desirable for strength at the corners.

Since certain changes may be made in the above product without departing from the scope of the invention herein involved it is intended that all matter contained in the above description and shown in the accompanying drawing, shall be interpreted in an illustrative and not in a limiting sense. 1
