Application August 10, 1955, Serial No. 527,501

1 Claim. (Cl. 160-354) This invention relates to door body construction, especially for resilient door bodies.

Reference is made to my pending patent application, Serial No. 311,917, tiling date September 27, 1952, now Patent No. 2,720,920.

One object of my invention is to provide a separator between the front and rear casings of a door body or the like, which separator has barriers at the outside whereby the filler material that is commonly used in door bodies will not accumulate within the contines of the separator and create bulges at such points.

Another Object is to provide such a separator having a connector web between front and rear flanges, and with said barriers, so constructed that the centrally located, connector web provides the principal rigidity, and the barriers yield when a door body containing such separators is struck vigorously, as by a moving truck or the like.

A further object is to provide such a separator of simple construction, that can be manufactured at a relatively low cost and can conveniently be used in the construction of a door body.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a combination and arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and therefore, I am not to be limited to the construction disclosed by the drawings nor to the particular parts described in the specifications; but am entitled to all such changes therefrom as fall within the scope of my claim.

In the drawings:

Fig. 1 is a front elevational view of a door body having my separators therein.

Fig. 2 is a top plan View of said door body.

Fig. 3 is an enlarged, sectional View taken on the line 3 3 of Fig. 1.

Fig. 4 is a fragmentary, perspective View of a door body, part of the lower wear strip, and front casing, being shown broken away to expose the interior of the door body.

Fig. 5 is a perspective View of my separator, broken away.

As illustrated, my door body has an outside front casing and an outside rear casing 12, which casings are spaced apart, and may be made of sheet rubber or plastic, for instance. Said door body also has a stile 13, or other reinforcement, at its inner side, while there is another stile 14 or reinforcement of the outside edge. There is a nose member 15 at the outside edge of the door body.

In the space between the casings I provide one or more separators 16 which are usually made of rubber or a rubber composition, preferably being resilient and flexible. Each separator has a front flange 18 and a rear ange 20 which are attached to said

casings

10 and 12 respectively, as by an adhesive. A web or connector 22 is integral with and extended to serve as an anchor and to ice yieldingly withstand the principal strains and stresses the door is subjected to when opened by a moving truck, or other moving equipment, striking against it.

Since empty space between said casings is lled with rubber coated fibers or other yieldable liller material F, it is undesirable to leave any pocket-like space for said filler material to steadily accumulate in, such as between said anges and said connector web. Such accumulations pile together, and bear against and tend to expand said flanges, thus causing forward and rearward bulges in the door body which are unsightly and result in uneven distribution of said filler material F.

To prevent the accumulation of filler material aforesaid, and yet have said web 22 serve its purpose as the principal mainstay of my separator between the front and rear casings of the door body, I provide barriers which are, as shown, at the top and bottom of my separator. A front barrier 26 extends at a right angle to, and from the front edge of said front ange 18 rearwardly, being shown as the upper, front barrier in the drawing. Another front barrier 28 extends at a right angle to, and from the front edge of said front ilange 20 rearwardly, being shown as the lower, front barrier in the drawing.

A rear barrier 30 extends at, a right angle to, and from the rear edge of said rear flange 20 forwardly, being shown as the upper, rear barrier in the drawing. Another rear barrier 32 extends at a right angle to, and from the rear edge of said rear flange 20, being shown as the lower, rear barrier in the drawing.

These front and

rear barriers

26 and 30 respectively, are adjacent each other at their free edges, but spaced slightly apart, such as s inch apart, and this is likewise true of the other two front and

rear barriers

28 and 32, the free edges of each said pair of barriers being so close to each other that no appreciable amount of the filler material F will pass beyond the barriers into the contines of my separators.

By providing said barriers in parts, such as the half sections shown, said web or connector 22 provides the principal rigidity in my separator, since said barriers can freely yield and become temporarily deformed, and separate from each other.

At the front of the door body, a rubber wear strip 34 is shown, that extends a short distance from the bottom upwardly.

What I claim is:

A door body comprising a resilient, front casing and a resilient, rear casing spaced from said front casing, and an elongate, resilient, separator extending crosswise of said door body embodying two oppositely disposed flanges between and attached to said casings, a connector web attached to intermediate points of, and extending between said iianges, a pair of barriers extending from edges of said two flanges towards, and to points adjacent, each other, another pair of barriers extending from edges of said anges that are opposite the rst-mentioned edges, towards, and to points adjacent, each other, said web being spaced from said barriers, and filler material between said casings and in contact with two of said barriers, the two barriers of each said pair being suiciently close to prevent an appreciable amount of said filler material from passing between them.
