1 Claim. (Cl. 292-343) This invention pertains to door stops of the type which may be placed upon the floor and pushed under a door so as to hold it against swinging.
An object of this invention is to provide a simple stop which will have just the right degree of resiliency to provide the proper pressure on the floor and the door when forced into position under a door to produce suflicient frictional resistance to prevent movement of the door relative to the stop, and also movement of the stop relative to the floor. Another object of this invention is to provide such a stop of simple structure which may be manufactured on a mass production basis at a very low cost.
Generally stated, the stop is molded of rubber or other resilient material, preferably a rather stiff material which requires a substantial force to deform it. It is molded to have an elongated body of rectangular cross section, preferably square and tapered toward one end, with a hollow similarly tapered extending axially into the body from its larger end. Such a device, when pushed under a door, yields by deforming its side walls and produces a very substantial pressure between the floor and the door.
A preferred embodiment of this invention is illustrated in the accompanying drawings, in which- Fig. 1 is an end view of a door stop embodying this invention;
Fig. 2 is a side view of the same;
Fig. 3 is a bottom view of the same;
Fig. 4 is a longitudinal section on line 44 of Fig. 3;
Fig. 5 is a section on line 5-5 of Fig. 2; and
Fig. 6 is a section on line 6-6 of Fig. 2.
As shown in the drawing, a body 1 is formed by molding or otherwise, having an elongated tapered form as shown in Fig. 2. In the illustrated embodiment, the cross-sectional shape of the body is square as shown in Figs. 1, 3, and 6.
The tip or smaller end of the body 1 is blunted by forming thereon a short section 2 having an increased taper with respect to that of the body 1. This short section is formed with a square end 3 which makes it easier to mold than if this section were continued to a point. The blunted end portion 2 also shortens the body at that portion which is seldom active when in use. It also enhances the durability by providing a short end of smaller size which is not active in performing the functions of the door stop and may take abuse which might otherwise mar the active surfaces.
The body 1 is formed with an elongated hollow 4, extending axially into the body from its larger end, as shown in Figs. 2 and 4. As shown in the drawing, this hollow is of frusto-conical shape and extends into the body a substantial distance, usually at least two-thirds of the length of the body. As may be seen from Figs. 5 and 6, this hollow 4 forms side walls which are comparatively thin at their middle portions, and therefore are capable of yielding under pressure and providing a resilient force resisting such pressure.
It will be seen, therefore, that this invention provides a simple structure which is easily molded and therefore cheap to make. The outer walls of the body are smooth so that they make close contact with the floor and the bottom of a door. When forced under a odor in the usual manner, the vertical side walls will yield by bending outward and will then exert a yielding force to retain the stop in place.
Various changes may be made in the details of construction, within the scope of the appended claim, without departing from the spirit of this invention. Parts of the invention may be used without the whole and improvements may be added while retaining some Or all of the advantages of the invention.
I claim:
A door stop comprising, an elongated tapered body of substantially square cross-section molded of relatively hard rubber, said body having its smaller end blunted by a short section of increased taper, said body being formed with an elongated frusto-conical hollow extending axially thereinto from its larger end for substantially two-thirds of its length thereby forming yielding side walls for said body.
