DOOR KNOB SHIELD

This invention relates to a painter's tool and more particularly to a door knob shield for use by a painter in readily and quickly painting a door zone about a door knob.
In the past there has been a problem often encountered by painters painting a building where there are numerous doors. Because door handles are ordinarily of a different material than is the door, it is necessary to, first, mask around a door knob or, alternatively to paint about it very carefully and hence slowly so as to define pre-cisely and neatly the line between the door knob base and the door. This invention is of a shield which includes a handle extending from a coaxial skirt which is sized to nestingly receive the door knob with the skirt end in close abutting relation to the door at the base of the door knob so that paint may be applied to the door about the base of the door knob without getting paint on the door knob. By using the tool painting of a door can take place quickly and without the attendant labor of prior art techniques.

It is an object of this invention to provide an improved door knob shield for use by painters in guickly and readily painting about a door zone adjacent a door knob and which is composed of a handle with a coaxial skirt siæed to receive the door knob and with the skirt being adapted to abuttingly engage the door abou-t the ~k F7Q/00166-4.109 ~ 1 7~273 door knob and which tool may include inserts to accom-modate various size of door knobs.
In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings in which:
Figure 1 is a view illustrating the use of the instant invention;
Figure 2 is a view partly broken away and illust-rating the details of the invention;
Figure 3 is a view similar to Figure 2 and illust-rating the insert shown in Figure 2 removed from the leading or working end of the tool; and Figure 4 is a view partly in cross section showing the insert which has been removed from Figure 2.
Referring to the drawings wherein like reference characters designate like or corresponding parts through-out the several views, the numeral 12 generally designates a portion of a door adjacent a door knob generally desig-nated by the numeral 14 having a base or flange 16 which is secured to the door in a conventional fashion. The door knob shield is generally designated by the numeral 20. It is seen to include a handle 22 and a skirt 24 at the forward end 26. The skirt defines a chamber 28, see Figure 2. The chamber is open at the distal end 30 and may be beveled as at 32. Alternatively, as best seen in Figure 4, an insert 33 having an annular portion with a threaded nose 34, sized for threaded engagement with internal threads 36 at the mouth of the skirt 241 of the modified form of the device of Figure 3. Conventionally, F70/0016~-4.109 3 ~71273 one or two turns is all that is required to remove or install the insert. The insert may be of two or three sizes for the purpose now to be described.
In use, as shown in Figure 1, the skirt is posi-tioned with the interior wall 38 in close abutting rela-tion to the flange 16 of the door knob and with the knob 14 within the chamber 28 of the skirt. As the handle is grasped, and the shield is in the position shown, the door may be painted quickly and easily, either by a brush or spray about the flange without getting paint on the metal of the door knob. For different size door knobs, an insert, see Figure 4, may be threadably engaged in the mouth or end 40, Figure 3, by engaging the exterior threads 34 of the insert with the internal threads 36 of the skirt. Depending upon the size of the flange of a door knob, an insert as shown in Figure 4 is selected.
It is thus seen that there has been provided a simple and inexpensive tool for use by painters in shield-ing a door knob so that the door surface adjacent the door knob when installed may be quickly and easily painted in a smooth clean job which does not re~uire expensive masking tape and other time-consuming procedures.
In accordance with the foregoing, it will be appreci-ated that while the instant invention has been shown and described in what is considered to be a practical and preferred embodiment, departures may be made therefrom within the spirit and scope of this invention which is, therefore, not to be limited except as set forth herein-after.

Claims (2)

F7P/00166-4.109 The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A door knob shield comprising an elongate handle having a first end and a second end, a skirt having a closed end and an open end and means securing the closed end in coaxial relation with the handle, said skirt being sized for nestingly receiving the door knob and said open end of said skirt being sized to abut the surface of a door adjacent a door knob, said skirt is internally threaded adjacent said open end and an annular ring is provided in threaded engagement with said skirt, said ring being in-serted within said skirt and adapted to accommodate the door knob, where different sized rings can be individually attached to the threaded end of the skirt to accommodate different sized door knob bases.
