Description

Patented Feb. 16, 1932 UNITED STATES WILLIAM. D. CABNAL, OF AKRON, OHIO DOORSTOP Application filed September 25, 1981. Serial No. 565,186.

This invention relates to door stops and its general object is to provide a device of that character, that is not only capable of firmly securing a door in any desired open position, but will not in any way damage the door or its securing or supporting means, as the device is formed from resilient material such as soft rubber or the like, therefore excess pressure against the door is impossible.

in Another object of the invention is to provide a door stop that is simple in construction, inexpensive to manufacture and extremely eflicient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a perspective view showing my door stop in use.

Figure 2 is a fragmentary sectional view taken through the door and my stop respec tively.

Figure 3 is a view of the door stop partly in section and in elevation.

Figure 4 is a bottom plan view thereof.

Referring to the drawings in detail, the reference numeral 1 indicates the body of my door stop and it will he noted that the body is elongated and wedge shape, the bottom thereof being fiat while the upper surface or top is inclined to provide the door engaging surface to set up a wedging action as will be apparent.

The bottom is corrugated as at 2 for a portion of its length, and the corrugations extend transversely thereof as will be noted upon inspection of Figure 4. The corrugations prevent the stop from slipping when in use, and cooperate with the material from which the body is formed, for that purpose, as the body is formed from resilient material such as rubber or the like and therefore has a tendency to grip a floor surface.

Formed in the enlarged portion of the body and extending inwardly from the bottom thereof is a recess 3 which is in the form of a bore and extendin across the recess and having its ends em edded in the body is a pin 4 which is arranged approximatel midway between the ends of the recess or the purpose of receiving a coil spring 5, the latter being arranged with respect to the pin, so that the pin extends through one of the convolutions thereof as best shown in Figure 3. By this construction, it will be obvious that the coil spring can be adjusted with respect to the floor surface, merely by rotating the coil spring, and it cooperates with the body in plrging the latter in engagement with the cor.

From the above description and disclosure of the drawings, it will be obvious that I have provided a door stop that will firmly secure a door in any desired open position, due to the serrations or corrugations 2, as well as the fact that the body of the stop is formed from resilient material such as rubber, and the coil spring cooperates with the material in urging the body into contacting engagement with the door. This material will naturally give under the pressure of the door as will be 30 noted upon inspection of Figure 2, with the result that casual movement of the door will be prevented when the latter and the door stop are arranged in the positions as shown in Figures 1 and 2.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:

1. A door stop of the character described comprising a body formed from resilient material and having a flat bottom and an inclined upper surface, the bottom being provided with serrations, said body having a recess formed therein, and a coil spring adjustably associated in said recess for cooperation with the body to urge the latter in contacting engagement with the door.

2. A door stop of the character described comprising a body formed from resilient material and having a flat bottom and an inclined upper surface, the bottom being provided with serrations for a portion of its length, said body having a recess arranged in the enlarged portion thereof and extending from the bottom, a pin disposed across the recess substantially midway its ends, a

coil spring received by the pin with the latter disposed through one of the convolutions thereof in a manner whereby the coil spring is adjustably associated in said recess, and said coil spring cooperating with the body to urge the latter in contacting engagement with the door.

In testimony whereof I aiiix my signature.

WILLIAM D. CARNAL.
