A compliant sheet covers 56 References Cited said pad, and provides an exterior cover for the door UNITED STATES PATENTS body 854,135 5/1907 Whittemore 161/102 2 Claims, 3 Drawing Figures DOOR BODY The principal object of my invention is to provide a door body that is intended to be forcibly opened by impact of a cart or truck pushed against it, yet is sufficiently resilient to return to its normal shape after being struck.

Another object is to provide such a door body that is strong enough to withstand said impacts repeatedly for an indefinite length of time, yet is simple in construction and relatively inexpensive to manufacture.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement of parts such as is disclosed by the drawing. 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 drawing nor to the particular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my invention.

In the drawing:

FIG. 1 is a front elevational view of my door body.

FIG. 2 is a sectional view, greatly enlarged, taken on the line 2-2 of FIG. 1.

FIG. 3 is a sectional view similar to FIG. 2; of a modified form of my invention, and showing the front extremity of said door body.

As illustrated, my door body has a core of relatively firm sheet material that is somewhat resilient and non bendable when serving as part of the main body of a door that is regularly opened by forceful impact, as when a moving cart or truck strikes it. It may be made of a thermo-forming material, or another suitable material, such as an acrylic polyvinyl chloride alloy plastic sheet. It may be one-eighth inch thick, for instance.

At the front and rear of said core 10 is a yielding resilient pad or sheet 14, which commences at a stile 20, later referred to, and extends at one side of said core 10 to the outer end of the door body and then reverses and extends inwardly at the opposite side of said core 10 and terminates at the edge of said stile 20. This sheet 14 is shown as a unitary one, and is thicker than said core 10 and preferably is more than two times as thick. For instance, said sheet 14 may be one-fourth or onehalf inch thick while said core may be one-eighth inch thick. This sheet or pad 14 is made of yieldable, resilient material such as sponge rubber, urethane or neoprene, and is relatively resilient compared to said core which is relatively stiff, although said core, as well as said sheet, will yield upon forcible impact.

A cover sheet or skin 16 of compliant material, such as rubber, extends around the door body, including said stile 20, extending to the outer end of said door body, beyond said core 10 and pad 14 to provide a flexible nose 18, as shown in said FIG. 3. Said cover sheet l6 continues from said nose 18 to said stile 20. It is cemented to said stile and pad.

Said door body has a stile or mount 20 at its inner end, which may be formed of wood, plastic or extruded aluminum, for instance, preferably being solid and extending the full height of said body. It has a slot 21 formed therein extending from top to bottom, and from its outer end inwardly a relatively short distance such as l /zinches. This slot 21 receives an inner end portion of said core 10 which is cemented or pinned, or both, to said stile. The cover sheet 16 is covered on the outside by a cap 22 where it overlaps said stile. Said cap is preferably made of metal that extends around said stile and a post 32, later referred to.

Said stile 20, cover sheet 16 and cap 22 are shown as retained by a bolt 24 extending through them, on which a head 26 is formed. Said cover sheet 16 and cap 22 are further retained in position by screws 28 and 30 that enter said stile 20.

A privot post or pipe 32 extends from top to bottom of said door body at the inner end thereof, being fastened by a pin 34 extending through said post and cap 22 and having a head 36 formed thereon. Said door body may be provided with a window 40 as shown in said FIG. 1.

In said FIG. 3 I show a modified form of cap 22a, without said post 32, and with said cover sheet 16 extending to the inner end of said door body. The latter sheet 16, said stile 20 and said cap 220 are fastened together by screws 42 and 43. A hinge 44 is fastened to the inner end of said cap 22a in any well-known way.

In forming said flexible nose 18 the material of said resilient pad 14 is compressed where a tum is made at the point beyond the outer end of said core 10 to the outer end of said cover sheet.

What I claim is:

l. A door body comprising a core extending straight and of relatively firm but resilient material, pad means on opposite sides of said door of compressible but resilient material, the latter material being more resilient than said core material, a cover sheet of compliant material exteriorly of said pad means and core and providing a cover for said door body, a solid stile forming the inner side portion of said door body and having a slot extending inwardly from the inner end portion of said body, a portion of said core extending into said slot, said pad means terminating at said stile, said pad means being unitary and reversing itself beyond the outer end of said core.

2. A door body as in claim 1, the portions of said pad means reversing itself being compressed between the outer end of said core and the inner end of said cover,

said core being non-bendable.
