UNITED STATES PATENT. OFFICE.
ALEXANDER S. HERDMAN AND GUY L. THOMAS, OF AKRON, OHIO.
DOORKNOB COVER.
Application filed March 23, 1926. Serial No. 96,746.
This invention relates to door knob covers and more particularly to a device for covering the ordinary door knob applicable to the door knob while the same is in its usual position and providing the knob with a surfacesuch that the knob is fully cushioned to prevent damage thereby to objects with which it may come into contact when the door is swung in the open position.
A further and more specific object of the invention is to provide a resilient cover engaging and by its own resiliency closely fitt ng the door knob, this cover at once providing a cushion for protecting objects against damage by the knob and a means for grasping the knob to turn the same when the hands are Wet and slippery.
These and other objects we attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration isshown a preferred embodiment of our invention and wherein:
Figure 1 is a side elevation of a door knob having a cover constructed in accordance with our invention applied thereto;
Figure 2 is a front elevation thereof;
Figure 3 is a sectional view taken through the cover while in position upon the knob;
Figure 4 is a section through the cover taken on the line 4-4 of Figure 3.
Referrin now more particularly to the drawing. the numeral 10 indicates a door knob and 11 a covering therefor preferably formed of live rubber of substantially the same contour as the door knob to which it is to be applied. At present, a circular knob has been illustrated, but it will, of course, be understood that the cover may be modified to adapt it to oval, square or other types of knobs. The cover is substantially in the form of a cup, the bottom wall 12 of which engages the outer surface of the knob when the cover is in applied position. The mouth 13 of this cup is of less size than the greatest diameter of the knob so that the cover must be sprung into place thereon and will not slip or fall therefrom. The bottom wall 12 hereinbefore referred to may be, if so desired, provided with corrugations 14 which may be arranged upon either the inner or outer surface of the cover. ()n the present illustration, these are shown as arranged upon both surfaces of the cover, those upon the inner surface serving to prevent slipping of the covering upon the knob while those upon the exterior serve both to prevent slipping of the hand upon the cover and as a means for ornamenting the cover. The interior corrugations also serve to increase the cushioning effect of the covering.
Other changes being possible in the construction hereinbefore set forth without departing from the spirit of the invention, we do not limit ourselves to such specific structure except as hereinafter claimed.
We claim 1. As an improved article of manufacture, a cover for a door knob comprising a cupshaped elementof resilient material of substantially the same contour as the door knob to which it is to be applied, said element having a mouth of less size than the greatest diameter of the knob, the wall of the cup for contact with the face of the knob being interiorly corrugated to increase the cushioning effect. f 2. As an improved article of manufacture, a cover for a door knoo comprising a cupshaped element of resilient material ofsubstantially the same contour as the door knob to which it is to be applied, said element having a mouth of less size than the greatest diameter of the knob, the wall of the cup for contact with the face of the knob being interiorly corrugated to increase the cushioning efiect,and the outer surface being also corrugated to afford a better grip to prevent slipping of the hand upon the cup.
In testimony whereof we hereunto affix our signatures.
ALEXANDER S. HERDMAN. GUY L. THOMAS.
