SNUBBER APPARATUS FOR A DOOR Filed Sept. 22, 1965 United States Patent 3,353,857 SNUBBER APPARATUS FOR A DOOR William E. Mongor, Morrisburg, Ontario, Canada, assignor to Oliver C. Eckel, Carlisle, Mass. Filed Sept. 22, 1965, Ser. No. 489,349 2 Claims. (Cl. 292-157) ABSTRACT OF THE DISCLQSURE A spring-projected door snubber mounted on a frame adjacent a flexible door. As the door closes it cams the snubber and is received in a recess therein. A push on the door flexes it out of the snubber recess.

This invention relates to a snubber apparatus for a door especially a resilient one.

One object of my invention is to provide novel snubber apparatus that will, when it reaches closed position, stop movement of a door and retain it in normal or closed position indefinitely even though wind blows against it or there is other involuntary pressure against it.

Another object is to provide such snubber apparatus that is especially suitable for use with a door that yields, such as a rubber or other type of resilient door, so that the door may readily be freed from a position where it is retained by the snubber.

A further object is to provide such apparatus that is endurable and will remain in working order although a door is opened and closed many times a day.

A still further object is to provide such apparatus that has relatively few parts, is simple in operation, easy to install, and is relatively inexpensive.

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 claims.

In the drawing:

FIG. 1 is a front elevational view showing double doors in normal or closed position, with my apparatus in mounted position so retaining the doors.

FIG. 2 is a side elevational view of my snubber alone.

FIG. 3 is a bottom plan view of said snubber.

FIG. 4 is a sectional view, enlarged, taken on the line 44 of FIG. 1.

FIG. 5 is a view similar to FIG. 4; but showing a door bending as it moves out of snubber recess.

FIG. 6 is a view similar to FIG. 4; but showing a door returning to closed position.

As illustrated, my apparatus has a snubber 10 the main body 12 of which has a recess or bight 14 intermediate opposite sides. The upper edge 16 thereof extends continuously horizontally as shown, while the

lower edges

18 and 18a extend diagonally upward and outward from opposite sides of said recess 14. Thus these latter edges provide outwardly tapering portions that serve a purpose later explained. Said body 12 is preferably metal, such as a casting of aluminum alloy.

At opposite sides of said recess 14, holes 20 are provided that extend through said body 12 between the upper and

lower edges

16 and 18 respectively, the lower portions of said holes 20 being enlarged as at 22 to provide countersinking space.

Above and spaced from said snubber, fixed supporting means are provided shown as a door frame or header 24 having an attaching or connecting portion 26 shown extending horizontally. The latter has two holes 27 therethrough internally screw-threaded and which are in alignment with said holes 20.

Pin members 28 shown as bolts have heads 30 that movably extend into countersunk portions 22 of said holes 20 being spaced inwardly from said lower edges. From said heads 30 the shank or elongate portions 32 extend through said holes 20 through the space between said snubber and connecting portion 26 and into said holes 27 with which they screW-threadedly connect. Nuts 34 on said elongate portions normally bear against said connecting portion 26 and serve to lock said pin members 28 in predetermined position in said portion 26. Thus the normal relative positions of said snubber 10 and said header portion 26 is maintained as shown in FIGS. 1 and 4. Compression springs 36 around said elongate portions 32 are desirable since they serve as leveling means for said snubber. They bear on said nuts 34 and said snubber upper edge 16 as shown.

In normal position one or more well-known doors D extends into one or more said recesses 14 were each is retained against involuntary movement, such as may be caused by wind blowing against the same. Also swinging of a door back and forth is prevented.

When purposely opening it, a said door D bends and yields, snapping out of the said recess 14. The closing movement of the door cause said snubber 10 to rise until a door extends into said recess 14 at which point the snubber drops to normal position as shown in said FIG. 4, holding the door against drafts.

To adjust the position of snubber 10 relative to the header 24, said nut 34 is moved downwardly to unlocked position. Then said bolt 28 is screw-threadedly moved upwardly or downwardly to the desired position, whereupon said nut 34 is again moved to locking position in contact with said heater attaching portion 26.

What I claim is:

1. In combination, a snubber, a door, and a door frame normally spaced from said snubber and door, said snubber being directly above said door when the latter is in normal position, said snubber having a recess therein intermediate opposite sides and having holes extending upwardly therethrough, said door extending into said recess, and pin members freely extending into and retained in said holes and connecting with said frame, said frame having screw-threaded holes in alignment with said snubber holes, said pin members having screw-threaded portions screw-threaded1y connecting with said latter holes, and nuts screw-threadedly connected with said pin member screw-threaded portions and outside of and normally bearing against said frame to thereby hold said pin members in predetermined position, said door being resilient and adapted to bend when being forcibly moved out of said snubber recess.

2. In combination, a door, a snubber, and a door frame normally spaced from said snubber and door, said snubber being directly above said door when the latter is in normal position and having a recess therein, means to movably attach said snubber to said frame, said door having a resilient portion that enters said recess and is adapted 3 4 to bend when being forcibly moved out of said snubber 1,044,412 11/ 1912 Newton.

Claims

2. IN COMBINATION, A DOOR, A SNUBBER, AND A DOOR FRAME NORMALLY SPACED FROM SAID SNUBBER AND DOOR, SAID SNUBBER BEING DIRECTLY ABOVE SAID DOOR WHEN THE LATTER IS IN NORMAL POSITION AND HAVING A RECESS THEREIN, MEANS TO MOVABLY ATTACH SAID SNUBBER TO SAID FRAME, SAID DOOR HAVING A RESILIENT PORTION THAT ENTERS SAID RECESS AND IS ADAPTED TO BEND WHEN BEING FORCIBLY MOVED OUT OF SAID SNUBBER RECESS.
