DOOR STOP William C. Barnes, Jr., and Ewing R. Dryden, In, El Paso, Tex.

This invention relates to a door stop for maintaining a swinging door in a desired position.

The principal object of this invention is to provide a door stop which may be easily and detachably applied to the base of a door so as to hold such door against accident or movement in either direction.

One of the novel features of the device includes means of eccentrically mounting a crank to which arms are attached for holding an eccentric stop member, the means for supporting the crank being offset from spring means so as to cause the stop member to be directed into either a floor engaging position, or a retracted position.

Still further objects of the invention reside in the provision of a door stop member that is strong, durable, highly efiicient in operation, simple in construction and manufacture, constructed from a minimum number of parts, and which will be relatively inexpensive to produce out of readily available materials.

These, together with the various and ancillary objects of the invention which will become apparent as the following description proceeds, are attained by this door stop, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure l is a perspective view showing the door stop comprising the present invention and operative installation on the bottom portion of a door;

Figure 2 is an enlarged vertical sectional view of the door stop showing it in its operative position, and showing the retracted position thereof;

Figure 3 is an enlarged side elevational view showing the construction of the door stop member comprising one important feature of the invention;

Figure 4 is an enlarged sectional detail as taken on the plane of line 4-4l of Figure 3.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates a door on which the invention in dicated at 12 is adapted to be in place.

This device includes a substantially U-shaped clip having a bottom wall 14 to which

side walls

16 and 18 are attached. The clip may be formed from a suitable spring steel, or any other convenient material having the desired characteristics, and is adapted to embrace the sides of the door 10.

Integral with and pressed from the

side walls

16 and 18 of the clip are ears 20 which are extended outwardly from the

side walls

16 and 18. Suitable apertures are formed in the cars 20 and they provide means for journaling a substantially V-shaped crank 22 between each pair of cars on either side of the clip. Arms 24 are integrally formed with the crank and extend downwardly therefrom. The arms 24 with legs 26 at their free ends which extend at right angles to the arms 24. Pivotally mounted about the legs 26 are cam shaped stop tates Patent 2,169,5 5 Patented May 31, 1955 members 28 which have a floor engaging surfaces Sil eccentric from the axis of rotation of the stop members 28. The stop members are preferably made from ribbed rubber, but may be formed from any other suitable ma terial. These substantially L-shaped ribbed feet provide a secure engaging surface.

Lugs 32 are pressed from the end walls. 16 and I3 and have apertures therethrough to which one end of springs 34 are secured. The other ends of the springs 34 are 0 attached to the apices 36 of the V-shaped cranks 22.

The ends of the springs 34 are mounted for pivotal move ment and in action will constantly urge the apices 36 toward the lugs 32. As the ears 20 hold the crank arms 22 outwardly from the lugs 32, the springs 34 will constantly urge the crank arms 22 and hence the arms 2d together with the stop members 28 enter into an engaged position or a retracted position as shown by dotted lines in Figure 2.

In operation, the door may be swung toward its desired open position and then the door stop members 23 may be grasped and pulled downwardly from its retracted position until the arms 24 are positioned downwardly to some extent. The door stop members 2% can then be released and the springs 34 will continue to pull the door stop members 28 downwardly until the floor engaging surfaces 30 contact the floor. With the door stop member 28 positioned on either side of the door, any movement of the door will be resisted.

Since from the foregoing the construction and advantages of this door stop are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications may readily occur to those skilled in the art after consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, accordingly all suitable modifications and equivalents amy be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A door stop comprising a U-shaped clip having side walls adapted to engage the sides of a door, pairs of cars including a pair of cars on each of said side Walls, V- shapcd cranks journalled in each of said pairs of cars, lugs on said side walls between said ears, springs terminally connected to said lugs and to said cranks at the apex thereof, arms attached to said cranks, and stop members each having an eccentric floor engaging portion, said stop members being pivotally attached to said arms and extending therebetween.

2. A door stop comprising a U-shaped clip having side Walls adapted to engage the sides of a door, pairs of ears including a pair of cars on each of said side walls, V- shaped cranks journalled in each of said pairs of cars, lugs on said side walls between said ears, springs terminally connected to said lugs and to said cranks at the apex thereof, arms attached to said cranks, and stop members pivotally attached to said arms and extending therebetween, said springs being pivotally secured to said lugs inwardly toward the door from where said springs are attached to said cranks to provide means for urging said stop members toward said door, each of said members having an eccentric floor engaging portion.
