FINGER GUARD Filed May 10, 1 944 Hens BY wmwm H TTORNEY Patented July 3, 1945 FINGER GUARD John B. Ghisnell, Barberton, Ohio, assignor to The Sun Rubber Company, Barberton, Ohio, a corporation of Ohio Application May 10, 1944, Serial No. 534,863
This invention relates to finger guards or finger pads.
An object of this invention is to provide a finger guard, of the type made of rubber or like flexible, resilient material adapted to be received over the end of the finger, with improved means in the interior thereof whereby is'assured circulation from end to end of the guard and whereby is obviated or greatly reduced the usual discomfort caused by perspiration due to lack of air circulation insidethe guard.
Other objects of the invention will be manifest from the following brief description and the accompanying drawing.
Of the accompanying drawing:
Figure 1 is a side elevation of a finger guard of the type embodying the invention.
Figure 2 is an end view as .viewed from the right thereof.
out filling the same or at least not to such an extent that passage of air through the grooves will be prevented. To this end the bottom cor- .ners 14-, I4 of the grooves l2 may be relatively sharp or without substantial fillets, as illustrated in Figure 4. -Ihe grooves are unrestricted along the lengths thereof and communicate freely to r the extremity of the open end of the casing (see still further enlarged scale, taken at 4-4 in Fig- :5
Referring to the drawing, the numeral l0 designates a finger guard, which may be an elongated hollow casing of vulcanized rubber or other flexible, resilient material, open at one end, and rounded at the other end, and proportioned and shaped to be received on the finger without materially affecting bending action of the first joint of the finger. The outer surface of the guard or casing H1, at the rounded end thereof, is provided with a suitable non-skid design, as indicated at H, to facilitate use of the guard as fo leafing papers or pages of a book.
The inner surface of casing l0 may have provided therein circumferentially spaced, relatively narrow grooves l2, l2, which extend longitudinally of the casing from the open end thereof to the inner or rounded end', these grooves defining relatively narrow ribs l3, l3. The grooves and ribs are'spaced substantially as shown so that when the guard is received on the finger the skin thereof will lay across the grooves with- Figure 3).
in the use of theimproved finger guard it is adapted to be received over the finger, substantially as shown in Figure 3, wherein a finger is shown in chain-dotted lines. As the guard is usually worn on the finger so that there is a small space'or chamber at tip orrounded end, air is free to circulate along grooves l2, between the open end of the guard and said spacev or chamber at the tip end. This circulation or air inside the guard prevents or materially reduces discomfort due to perspiration, as usually experienced by use of finger guards of known types.
Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claim.
What is claimed is:
A finger guard comprising a hollow elongated,
one-piece imperforate casing of rubber or like flexible, resilient material, said casing being open at one end and adapted to be received on the finger, said casing being provided around the inner surface thereof with circumferentially spaced ribs defining grooves therebetween and extending longitudinally from said open end of the casing to substantially the length of the easing, said grooves being unrestricted along the lengths thereof and opening freely at said open end of the casing, the inside corners at the bottoms of said grooves being substantially sharp or without substantial fillets, whereby when the guard is received on the finger the skin will lie across the grooves and yet provide maximum continuous space along the grooves for free circulation of air along the same and through the ends thereof opening at said open end of the casing.
