DOORSTOP Filed Jan. 31, 1932 Z 4 ENE 775752... a/IE EL/Z1 s77 Patented Nov. 14, 1933 t ar "STAT sis I DOORSTOP George Spratt and Julien F. Cullen, 'Eau I Claire, Wis.
Application January '21, 1932. "Serial No. 587,882
' 1 clai (01. :292 34s) Thisfinvention pertains to door stops, and more particularly to a stop designed for use in connection withswinging doors-and the like.
The invention hasprimarily for its object to giprovide' an exceedingly simple and inexpensive stop which will securely and releasably hold a door at a desired adjusted position when the stop is positioned under the bottom edge of the door. Incidental to the foregoing, 'a more specific object resides in the provision of a base provided with a yieldable member for wedging engagement with the bottom of the door.
A more detailed object is to provide a stop of i.-the foregoing characterwhich is formed integrally of resilient material, capable of retraction upon itself, to provide wedging engagement between the floor and the lower edge of the door. A still further object is to provide a stop 'fihaving the foregoing characteristics, and in which the bottom surface is formed to create a suction contactwith the floor to further insure against slippage when positionedupon floors having hard, smooth surfaces.
With the above and other objects in view, which will appear as the description proceeds,
' the invention resides in the novel construction,
combination and arrangementof parts substantially. ashereinafter described and more particuiilarly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.
In the accompanying drawing is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.
In the drawing: I
Figure l is an elevation of a stop constructed in accordance with one form of the invention, parts being broken away and in section to more clearly illustrate structuralv details. I Figure 2 is a'transverse section taken on the 5zcl'ine 2-2 of Figure 1.
'Figure 3 is a fragmentary detail of one way in which the bottom surface of the stop may be formed. 7 v
. Figure 4 is at View similar to Figure 1, illustrating the application of the stop to a door.
Figure 5 is an elevation of a modified form of the invention, parts being brokenaway and in section, and
- Figure 6 is an end elevation of the stop illustrated in Figure 5.
- Referring now more particularly to that form of the invention illustrated in Figures 1 to 4 of the accompanying drawing, the numeral 1 desig- 1 nates a base of rectangular, shape and provided With a central opening 2, for reception of the retraetible member 3, which, in the form of the invention illustrated, comprises a rectangular strip provided with a longitudinal groove 4 for reception of the lower edge of a door, the bottom width of the groove portion being substantially the same asthat of the longitudinal opening-2 to permit the same to be retracted within the opening when forced under a door, thus compensating for doors having various clearance With the floor.
The longitudinaledges of the strip 3 are preferably provided with lateral flanges 5 which extend over the base 1 adjacent the edges of the opening 2, thus serving as a stop for retraction of the strip 3, and also materially reinforcing the same. I
As best illustrated in Figures 1 and 2, the ends of the fianges5 are projected beyond the door engaging strip 3, and are turned downwardly to connect with the ends of the base 1, thus serv ing to provide a resilient connection between the strip 3 and base 1, which permits the former to be forced downwardly upon the base when position under the bottom edge of a door, thus effecting a secure wedgingaction between the door and floor, to hold the door in the desired adjusted position. I
While the invention as heretofore described, may be constructed'in various ways, utilizing any type of material witha resilient connection between the base and door engaging strip, it is contemplated to construct the preferred form of the invention from a flexible material such as rubber and the like, which readily lends itself to an integral structure, either-moulded in a single unit, or formed in a plurality of units welded together. Obviously, any dimensions may be employed, depending upon the conditions for which the stop is to be designed. 7
While it is contemplated that the stop, as heretofore described, will effect a secure wedge between the bottom edge of "a' door andthe floor, to I retain the door in desired adjusted position, in some instances, where the stop is to be used on floors of smooth, hard finish, it may be desirable to provide additional means to insure the stop against slippage. It is therefore contemplated that the bottom surface of the base 1 may be provided with recesses 6, of any contour or shape,
to create suction action between the base and floor.
Another form of the invention comprises a structure illustrated in Figures 5 and 6, in which the door engaging strip 3' is inclined with relation to the base 1', and connected integrally therewith at one end. At the opposite end the strips 3' and 1' may be connected by U-shaped springs'7, which normally urge the strip 3 to its raised position, as illustrated, and at the same time permit the door engaging strip to be retracted upon the base 1, to function in the same manner as described in connection with the preferred form of the invention. It will further be appreciated that in the modified form of the invention, Where the same is constructed of resilient material, such as rubber, the springs 7 are assisted in their function by the integral connection between the opposite ends of the base and door engaging strip. Furthermore, the springs 7, which are embedded in the ends of the door engaging strip and the base, form projecting loops, which facilitate manipulation of the stop inasmuch as they provide convenient handles for inserting or removing the'stop.
In this form of the invention the vacuum cups 6' may also be utilized, if desired. However, it is understood that the same are not essential to the present invention.
From the foregoing explanation, taken in connection With the accompanying drawing, it will be readily seen that an extremely simple, inexpensive and efficient door stophas been provided, which can be readily inserted under a door to securely retain the same in adjusted position.
Attention is also directed to the fact that Where the stop is to be formed out of soft flexible ma-
