Abstract
A ski pole grip made up of a cylindrical central body grip part having a hole therein for receiving a ski pole handle. The body grip part has an upper and a lower end and an intermediate part. The intermediate part is generally cylindrical and adapted to be received in a hand of a skier with the palm of the body a first side and the fingers extending around the second side of the intermediate part. A mushroom-like top part is integrally attached to the upper end of the hand engaging part and extends outward from the sides and front thereof. The front part of the mushroom-like top acts as a snow guard and is attached to the front side of the top and extends downward. A thumb support is attached to the inner side of the body part and extends upward and terminates in spaced relation to the upper end. A recess formed at the front of one side of the thumb support receives the ends of the skier's fingers. A hand support is attached to the lower part of the body part at the outer side and extends upwardly. The mushroom-like top upper guard is attached to the second side of snow guard, extending downwardly and terminating adjacent the upper end of the lower guard. The upper guard and the hand support are adapted to receive the hand of a skier therebetween with the hand resting on the lower guard.

Description
Background of the Invention
Applicant has observed that the conventional ski pole grips provide little, if any, protection for the thumbs of a skier which are exposed and are injured in many skiing accidents. Because of the physical structure and anatomical location of the thumb it is especially vulnerable to injury, particularly when the skier is thrown forward. No prior ski pole grip is designed to adequately protect the thumb and hand.
Statement of the Invention
The aspects of this invention are: (1) the thumb rest which holds the thumb in a natural position with the rest of the hand and prevents the thumb from being jammed back. It prevents the thumb and fingers from being bent down and back so that the knuckles will not be dislocated. It also protects the index finger from being crushed, (2) the mushroom shaped shield or snow guard that extends out over the front and sides of the pole protects the thumb from being indured from above, (3) the undercut recess in the thumb support member below the thumb support surface saves material in the manufacturing process and provides a space for the tips of the skier's fingers which curve around the cylindrical grip, and (4) the guard that goes around the back of the hand replace the conventional leather straps. The lower extension is relatively stiff, flat, and provides a rest for the hand while planting a ski pole.
The primary purpose of the improved ski pole grip is to protect the thumb and hand of the skier. The thumb guard will keep the thumb of the skier on the thumb support against the body of the grip when the skier's hand impacts with the ski slope and other obstacle thus preventing the thumb from being broken and prevents other injuries to the skier's hand. The raised grip which merges into the guard is intended to hold the thumb stationary during the time that the thumb is against the body of the grip and to keep the thumb from being bent back by impact thereby breaking or fracturing the thumb.
The mushroom shaped snow guard has a generally convex top and concave bottom with its central part attached to the upper end of the cylindrical body. The snow guard extends out and down over the front and sides of the hand and is designed to protect the knuckles of the first two fingers of the hand and to prevent the thumb from striking with a direct impact and jamming the knuckles backwards. Very little of the mushroom shaped snow guard extends rearward beyond the hand grip so as not to interfere with the hand at that part.
The raised portion in the grip, or rearwardly extending protrusion, in addition to helping hold the thumb in place, also helps hold the pole out so that when the skier is reaching forward to plant his pole he does not have to turn his wrist up as fast and therefore releases pressure on the wrist itself.
Reference to Prior Art
Applicant is familiar with the following U.S. Pat. Nos.:
None of the patents shows a thumb guard, or a snow guard such as Applicant has disclosed.
Objects of the Invention
It is an object of the invention to provide an improved ski pole grip particularly shaped to protect the thumb of a skier.
Another object of the invention is to provide a ski pole grip especially suitable to protect the entire hand of the skier.

Detailed Description of the Drawings
Now with more particular reference to the drawings, the embodiment of the invention shown in FIGS. 1 through 6 shows a grip 10 for a ski pole 11 made up of generally elongated cylindrical body 12 having an upper end and a lower end. The lower end has means on it in the form of a hole to receive the upper end of the ski pole 11.
A mushroom shaped snow guard 20 has an upper convex surface 22 and a lower concave surface 26. The mushroom shaped snow guard 20 is integrally attached to the upper end of the generally cylindrical body 12 and extends foward and to both sides of the body 12. The peripheral edges of the mushroom shaped snow guard 20 extend downwardly, outwardly and overlie the thumb and hand of a skier.
A thumb support 19 is integrally fixed to the lower part and inner side of the cylindrical body 12 and extends inwardly toward the other hand and terminates in an upwardly facing thumb supporting surface 18 spaced from the upper end approximately half way along the cylindrical body 12.
The thumb support 19 is undercut on the front side 21, forming a recess 23, to receive the fingers 24 of a skier. As shown in FIG. 2, the fingers of a hand indicated at 24 may extend into recess 23 and thumb 25 may overlie thumb support surface 18. A rearwardly extending convex protrusion 17 is formed on thumb support 19. Protrusion 17 is generally hemispherical in shape and fits into the palm of the skier's hand. Protrusion 17 terminates on the thumb support surface 18 between the mushroom shaped snow guard 20 and the thumb support 19. Thus when a skier falls forward, the mushroom shaped snow guard 20 will engage the ground and protect the skier's thumb 25 and fingers 24 from injury.
A thumb guard 16 extends upwardly from the inner side of the thumb support surface 18 remote from the cylindrical body 12. Thumb guard 16 terminates in spaced relation and below a side edge 15 of the mushroom shaped snow guard 20. The overhanging part of the side edge 15 of the snow guard 20 prevents the snow from injuring the thumb supported on thumb support surface 18.
Hand support 14 is a relatively thin generally flat part integrally attached to the cylindrical body 12 and extends radially, outwardly from body 12 and terminates in a generally upwardly inclined surface adapted to support a hand. An overhanging part 13 of the mushroom shaped snow guard 20 terminates above and in spaced relation to the hand support 14 providing a space between the overhanging part 13 and the hand support 14 to receive a hand of a skier.
Generally the mushroom shaped snow guard 20 protects the thumb 25 from being jammed back. Mushroom shaped snow guard 20 also protects the index finger from being crushed when striking an object. Thumb support 19 holds the thumb in a natural position with the rest of the hand. The recess 23 below the thumb support surface 18 saves material in the manufacturing process of the ski pole grip and allows for fingertips to curve around the pole for the larger than average hand or for bulky gloves.
The traditional straps that go around the back of the hand are replaced by overhanging part 13 on the outer side of the grip 10. The protrusion 16 extends rearwardly of the grip with regard to a person using the grip. The word "forward" is also used herein with reference to the person using the grip.
The foregoing specification sets forth the invention in its preferred, practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
