United States Patent O 3,290,049 HANDLES'FOR SKI POLES AND THE LIKE Robert J. McDonald, 3229 Ardley Ave., Oakland, Calif. Filed Feb. 14, 1964, Ser. No. 344,998 Claims. (Cl. 280-11.37)

This invention relates to improvements in handles for ski poles and the like and more particularly to those handles which incorporate a retaining or wrist strap.

Ski poles are used by skiers for balance and traction and are notably essential in slalom and high speed downhill skiing. In these modes of skiing, enormous forces are exerted on the pole by the skier and it is imperative to provide a positive and comfortable gripping 1ocation for the skiers hand on the pole, for here is where these forces are most acute.

Straps are sometimes provided to insure against complete loss of the pole by the skier in case of temporary dislodgment. Thus the strap is attached to the handle of the ski pole and forms a loop, into which the skiers hand is inserted. In other words, the strap has its ends attached to the pole handle from whence the strap encircles the wrist of the skier.

In previous modes of attaching the strap to the ski pole handle, the strap emerged from juxtaposed points on the handle, usually near the top of the handle just above the gripping surface. This required the skier to grip a portion of the strap between the palm of his hand and the ski pole handle; and, as a more serious consequence, the hand could be pulled over the top of the handle leaving the pole free to dangle at the end of the The disadvantage of having a ski pole ailing at the end of ones Wrist, while plummeting down the slopes, is obvious. p

As an additional consequence the term skiers thumb has become an axiom among skiers. This refers to the many sprained and sometimes broken thumbs suffered by the users of the present type of strap which attaches to the pole at a single top location.

This invention further obviates the inadequate prole of the present ski pole handles which are designed to fit both the right and left hand and as a consequence it neither hand well.

Further shortcomings of present-day handles are similarly overcome, such as the danger of losing an eye or other injury when the butt end of the handle is thrust into -the face during an unexpected mishap. Some attempts have been made to relieve this danger, as by placing large spherical bulbs at the ends of the handle, but have proved to be inadequate.

Accordingly, it is a principal object of the present invention to provide a handle for ski poles which affords the maximum of comfort and safety to the user.

A further object of the present invention is to provide a ski pole handle and strap combination in which, in case of a users hand losing its grip on the handle, the strap will keep the pole next to the skiers hand in correct position for him to again grip the handle and regain control ofthe ski pole.

A still further object of the present invention is to provide a handle and wrist strap which obviates the disis also secured on the pole with the fastening means hidden from view.

Another object of the present invention is to provide a ski pole handle which incorporates the aforesaid features in an attractive and economically producible configuration.

Further objects and advantages of the invention will be apparent as the specication progresses, and the new and useful features of the handles for ski poles and the like will be fully defined in the claims attached hereto.

The preferred form of the invention is illustrated in the accompanying drawing forming part of this application, in which:

FIGURE 1 is a front elevational view of one side of a typical right hand grip made in accordance with the preferred form of the present invention but as it would be on a ski pole without the retaining strap in place;

FIGURE 2, a rear elevational view of the grip shown in FIGURE l and is the side diametrically opposite that shown in FIGURE l;

FIGURE 3, a view similar to FIGURE 2 but with the retaining strap in place;

FIGURE 4, a side View of the handle in FIGURE 3 slightly rotated to the right and shown as it would be gripped by a skier;

FIGURE 5, an elevational section taken substantially in the plane of line 5--5 of FIGURE 3 and illustrating how the strap is secured to the pole;

FIGURE 6, a section taken along line 6 6 of FIG- URE 3; f

FIGURE 7, a section taken along line 7-7 of FIG- URE 3; and

FIGURE 8, a sectional view taken along line 8-8 of FIGURE 3.

While only the preferred form of the invention is shown, it should be .understood that various changes or modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.

It should be appreciated that the grip illustrated is intended to be used with the right hand and that a left hand grip would be a mirror image of that illustrated.

As shown in the drawing the handle for ski poles and the like of the present invention consists basically of handle means 11 of elongated form adapted to provide a hand hold at one end of a pole 12, and a flexible strap 14 operatively connected to said handle means at longitudinally spaced

locations

16 and 17 therealong so that the handle means 11 and strap 14 cooperate to provide a loop adapted to engage and restrain the hand 13 of the skier.

As an important feature of the present invention the strap ends are separated where they engage the grip or handle. This separation could take the form of securing the strap ends at

points

16 and 17 as is illustrated Orrin other ways, the main feature being that the effective ends of the strap are separated and that a grip surface 18 is interposed therebetween to complete the loop. The preferred relationship of strap and handle is best shown in FIGURE 4, wherein the strap emerges from near the top of the handle, preferably at an angle as shown, and passes under the thumb, around the back of the hand and reenters the handle near the butt end of the hand.

This relationship of the strap ends overcomes several difficulties encountered in previous ski pole handle and wrist strap combinations. For instance, it will be -noted that if the hand is opened the gripping surface 18 will remain :near the palm of the hand and be'in a position to be readily regrasped.

It will be noted further that by separating the strap Vends the hand will be stopped from sliding any appreciable distance along the handle. Similarly the thumb joint, between the thumb and index finger, is not submitted to the full force of a blow as on previous handles.

Another important feature of the present invention is the mode in which the strap is secured to the ski pole. The strap emerging from the lower end of the handle, at 17, is directed downwardly and away from the handle. From here the strap makes a half twist and enters the upper end of the handle at 16, axially displaced and askew to the lower end.

Preferably', the length of the strap is adjusted by concealed means and the usual buckle is eliminated. Such concealed adjusting means may be of any suitable form. As here shown, the upper strap end 14a enters the handle through passageway 19 and is secured to the ski pole by suitable fastening means 21 such as a screw 22 held in hole 23 in ski pole 12; the other end- 14b enters the handle through passage 24 and is similarly secured to the ski pole by a screw 26 in hole 27.

In order to keep the attractive qualities that have been designed into the handle, the fastening means are hidden from view but are readily accessible. This is accomplished by relieving the interior bore 28 to provide

recesses

29 and 31 under the handle adjacent the

passages

19 and 24 into which the strap ends and the fastening means are lodged. To apply the handle and straps to a ski pole the handle is pulled on-to the end of the ski pole until the

passages

19 and 24 coincide with

holes

23 and 27; the strap ends are then secured to the pole with

screws

22 and 26. After the strap ends are so secured the handle is pulled further onto the pole until the strap ends and their fastening means are concealed under the handle in

recesses

29 and 31. This mode of attachment also keeps the handle 11 from moving axially or circumferentially on the pole 12. The usual plug in the end of th'e ski pole may be eliminated by swaging over the end of the pole as shown in FIGURE 5.

Adjustment of the strap length is here effected by securing the strap through suitable alternate holes 32, provided in either the shaft or strap. It will be appreciated that a considerable length of strap can be accommodated in the relieved recesses 29-31 by enlarging them, and that the strap could run entirely under the handle if desired. However, it is preferred to pass the end of the strap into the interior of the ski pole through a slot 35. In this manner, a wide range of adjustment may be accommodated while concealing the strap ends.

The handle is essentially an elongated sleeve 33 having generally

cylindrical Walls

34 and 36 defining an interior shaft receiving bore 28 and an exterior grip surface 1S. But, as an important part of the present invention, the profile of the exterior wall 36 is made to more comfortably and securely support a human hand and restrain the handle against twisting. In this connection the preferred form of the invention provides separate handles for each hand, that is, one for the right hand and one for the left.

The upper end of the sleeve 33 is closed by an enlarged end portion 37 which extends out over the grip surface 18. This enlarged extension or projection keeps the hand from being pulled over the top of the handle. The lower surface 38 of the projection is concave to fit adjacent the thumb and index finger (see FIGURE 4) while the upper end 39 of the end portion is convex to afford more protection in case the ski pole is jabbed toward the face. As best seen in FIGURE 4 the enlarged end 37 lays substantially in the contour of the upper end of the fist 13, combining therewith to present a large area of impact to absorb any blows imparted to the body or head by the ski pole.

Further hand conforming features of the grip surface include a protruding ridge 41 extending longitudinally along one side of the handle, and projecting therefrom. This ridge is formed to engage the fingers of the users hand and more particularly to fit within the crotch made by. the inside second joint of the fingers. When the skier is using the handle this ridge gives him a reference line to help orient the hand on the handle and also provides a means to keep the handle from rotating within his hand.

Similarly, the side of the grip surface substantially diametrically opposite the ridge 41 has a configuration 42 adapted to conform to the palm of the users hand and which also helps to position the hand and keep the handle from rotating. In addition, the palm conforming projection 42 forms an enlarged cross-section for the handle, under which relieved recesses 29 and 31 are provided.

The handle is preferably made of a moldable rubber to present a soft and warm feel to the hand. The elasticity and friction of the rubber also helps to keep the grip on the pole, the shaft receiving bore- 28 being made somewhat smaller than the diameter of the pole in such case.

So as not to detract from the smooth flowing lines of the preferred form of the ski pole handle it is contemcorporated into the general aesthetic harmony of the handle. This is achieved, as is clearly shown in the drawings, by running the line 43 along the apex of the first or nger-engaging projecting ridge 41, thence along the intersection 44 of the convexo-concavo end portions 3S and 39 and along the apex of the second or palm-engaging projection 4Z.

From the foregoing description, it is seen that I have provided a handle for ski poles and the like which affords improved comfort and safety to the user, which incorporates a retaining strap in a manner wherein the handle is retained in close proximity to the hand even though temporarily dislodged, and which interposes a grip surface between the strap ends, with hand conforming projections, all of which are incorporated in an attractive ensemble.
