United States Patent RESILIENT DOOR WITH OFFSET MOUNT Q Oliver C. Eckel, Carlisle, Mass.

Application July 20, 1955, Serial No. 523,326

4 Claims. (Cl. 20-16) Reference is made to my pending patent application, Serial No. 315,505, filing date October 18, 1952.

This invention relates to a door of the resilient type, particularly a door that is forced open by a moving truck or the like.

One object of my invention is to provide such a door with a flexing point located where it affects the durability of the door the least.

A further object is to provide such a door with a wear stripthat extends continuously from a point under a portion of a door mount to and around the nose and then to an opposite door mount portion.

A further object is to provide such a door that is strong enough to withstand the strains and stresses resulting from heavy trucks striking against it, is relatively simple to assemble, and makes a good appearance.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction and arrangement 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 specification; but am entitled to all such changes therefrom as fall within the scope of my claims.

In the drawings:

Fig. 1 is a front elevational view of my door shown movably attached to a door frame, said door being shown broken away vertically and horizontally.

Fig. 2 is an enlarged, sectional view taken on the line 22 of Fig. 1.

Fig. 3 is an enlarged, sectional view taken on the line 33 of Fig. 1.

As illustrated, pivot bearings 10, each having an opening 12 therethrough, are shown attached to a door jamb or frame F by screws 14. These pivot bearings are usually located at an upper portion of the door and a lower portion thereof, and there could be more than two if the size of the door so requires.

Attached to the main body 16 of the door at opposite face surfaces thereof door mount means are provided,

being here shown as two separate door mounts each hav-.

ing a retaining portion 20 that is curved, which portions extend towards each other, and preferably are adjacent each other at their free ends. In the space or opening provided between said curved retaining portions 20 a pivot member 30, later described, is received. Each said door mount also has an attaching portion 22 that is connected to a said retaining portion 20 by an offset portion 23 that extends between said portions 20 and 22, and from one end of which each said attaching portion 22 extends alongside a face of and parallel with the main body of the door for a short distance. Screws 24 extend through a said door mount attaching portion 22, passing through a wooden block 26 or other solid portion that forms part of said door body, and they screw-threadedly connect with A 2,774,117 v Patented Dec. 18, d

ice

the opposite attaching portion, as shown in said Fig. 2. A pivot member 30, shown in the form of a pipe that is circular in cross section, rotatably extends into said pivot bearing openings 12 and through the opening or space between the two retaining portions 20 of the door mount means, being attached to the latter by screws 32 that are shown extending from one said retaining portion 26, through said pivot member 30 and into the other retaining portion.

The interior of said main body 16 of the door has resilient supporting members 34, spaced apart, that bridge the space between opposite face surfaces of a resilient sheet or retaining casing 36. This latter extends from a point inside a said door mount attaching portion 22, commencing where the offset portion 23 ends, and continues along said block 26 and a face surface of the door body the full width of the latter, being turned over at the outer edge of the door to provide a nose portion 38. From there it continues along the opposite face surface of the door body, terminating when it reaches the other offset portion 23.

Outside of said retaining casing 36 is a wear strip 40 which may be made of rubber or other resilient, sheet material, and which extends from a point inside a said door mount attaching portion 22, commencing where said offset portion 23 ends. From there it runs along said block 26 and a face surface of the door body, parallel with said casing 36, being turned over at the door outer edge or nose, as at 42, and returning along the opposite face surface of the door body, terminating when it reaches the other ofiset portion 23.

'Said ofiset portions 23, by providing extra space, make it possible to extend an integral wear strip sheet to points where the door body begins, opposite a portion of said pivot member, thus providing the necessary strength and reinforcement for the full width of the door body. This avoids flexing of the door body at the end of said block 26 nearest a nose portion 42, which occurs if the wear strip has to commence there, and which adversely affects the wearing qualities of the door.

Ordinarily this wear strip 40 extends only about onehalf way up the body, as its main purpose is to absorb some of the shock and wear resulting from violent contact of the lower half of a door body with a moving truck or the like, as the later forces the door open.

What I claim is:

1. Door apparatus comprising a door body, door mount means embodying retaining portions at opposite faces of said door body having curved portions spaced apart and extending towards each other and providing an opening therebetween, a pivot member extending into said opening, means fastening said pivot member to said curved portions, two attaching portions, two ofiset portions connecting said retaining portions and said attaching portions and extending outwardly in ofiset relationship to said retaining portions, means fastening said attaching portions to said door body, a casing member having a portion extending from a point opposite and under a said attaching portion along a face of said door body, and another portion along the opposite face of said door body to a point opposite and under the other said attaching portion, a wear strip having a portion extending from a point opposite and under a said attaching portion along a face of said door body and a portion extending along the opposite face of said door body to a point opposite and under the other said attaching portion.
