Handle for a ski pole

The invention relates to a handle for a ski pole, which has a longitudinally extending cylindrical inside Has cavity.

Skiing is for the purpose of maintaining balance and speeding up and the bed's own from slopes, ski poles are required. The ski poles known years ago were not more than one cane or bamboo stick with one attached Belt pulley, which was commonly referred to as a snow ring or basket and located near the lower The end of the ski pole was attached, while at the top end

a handle was provided. Improved designs had a handle made of leather wrapped around the stick, which was extended like a button at the top of the stick and had a loop around the wrist the skier was lying around. In the last few years these ski poles have been improved significantly. The bamboo stick was replaced by metal tubes or fiberglass, the snow ring or plate consists of a light metal ring fc with injection molded hub and struts and the handle usually consists made of injection-molded plastic, which is adapted to the inside of the gloved hand of the skier.

Although these developments resulted in a lighter and more manageable Pole, was tested 2er ease with which handled a ski pole ^{^:?} N to nothing essential reached. So is z. B “In various ski maneuvers, it is essential to attach the ski poles precisely in terms of time and space. With the known ski poles, the skier must move the ski poles forward quickly using only his fingers and wrists and use them accurately. A certain additional control of the grip and stick is necessary at such moments, but even the latest ski pole grips are designed in such a way that the skier at least partially releases the ski poles at such moments, with the grip mostly between the thumb and forefinger is held when the ski poles are swung and used.

To enable such additional control is to

the present invention. The solution should be to this lead to the fact that an easier-to-use handle is available, which is an essential aid in the Control of the ski pole during numerous critical Moments while skiing made possible · At the same time should a grip can be created which is effortless and comfortable can be held and used and is easy to manufacture.

The solution to the problem posed led to a handle according to the invention of the type described at the outset, straps or similar devices being assigned to the elongated Mylindrisehen handle in order to provide substantial support when holding and using the ski poles. These straps are arranged so that they extend to the handle across the fingers of this comprehensive hand and hold them, preferably extending over all four fingers, just in front of the knuckles, and together with the handle umschlies sen the hand. Thus , the skier can move the ski poles through. Position your wrist and arms precisely using all your fingers and not just using your thumb and forefinger. The handle according to the invention preferably has an enlarged part at one end, this being flattened so that it offers space against the thumb comfortably lying there, a pattern of recesses arranged on the lateral surface of the handle being provided in the area of the inner palm, it- »To prevent the handle from slipping in the skier's hand. The handle is preferably made by spraying.

the left or right hand is provided, the head portion 14 is flattened and shaped so that a transverse to the Grip body 12 machined contact surface 30 the first Member of the thumb provides a comfortable facility

Two strap parts extend from the other side of the handle * They are of sufficient length to overlap and, together with the handle body 12, form an opening for receiving all four fingers of the skier's hand. The upper strap 32 extends outwards from the head region 14 and the lower strap 34 extends outwards from the lower end of the handle body 12. These two straps are arranged in such a way that they extend over the pinger and palm of the handle body 12 in the area of the The straps 32 and 34 are preferably widened when moving into the grip body 12) in order to create large contact surfaces for the hand sides and thereby the lever forces of the ski pole directed from the front to the rear over the largest area of the first links of the index and small ones Fingers to distribute »The outer surface of both straps are provided with notches 36 , which when they are put together by means of a buckle 38 in the Engage the corresponding parts of the buckle, as can be seen in FIG. 1, while preventing the straps from sliding out of the buckle 38. The handle body also has an elongated axial opening 42, which is open at its lower end, around the end of the ski pole 4 «This is normally closed with a wooden plug 44 · The handle can be on different

009838/0121

Way to be attached to the ski pole, preferably will this is effected by means of an axial opening 46 located in the handle, through which a screw 48 passes is screwed into the wooden plug 44, whereby the handle is removably attached to the stick. Although different Means can be provided to capture the back of the skier's hand or part thereof and to be held by the handle, the belt arrangement according to the invention is of a particularly simple construction which is easily adjustable · The straps work over a strong, movable area of the hand and allow an outward movement of the handle and stick by waving the hand and fingers away from the wrist and provide substantial protection for the hand and knuckle against scratches and damage from slalom goals, etc. It is also important that the handle of the invention does not cause the sticks to swing uncontrollably when falling of the skier allows, as is the case with the known grips, because the hands normally forward when falling or be swung backwards and the invention Grasp the ski pole at right angles to the direction of the fall and outward away from the skis keep. The handle according to the invention replaces the loops of the known handles, since all in a one-piece handle Features of handle and loops are included as well as other benefits.

Preferably, the handle and the strap are molded using the Sp: "szgußverfahren manufactured in a form as shown in Fig. 4 in section. The mold cavity 52 in which the

009838/0 121

Molten material for forming the handle is injected in a known manner, consists of two molded parts $ k and 56, the parting line 58 causing a seam 62 on the finished handle, as can be seen in FIGS. The mold further includes a removable mandrel 64 which defines the axial bore and screw opening of the handle. A removable insert 66 is preferably also present in the mold, which after the injection molding process and the separation of the mold parts can be removed from the mold part receiving it and thereby lifts the handle out of the mold. The cavity side of the insert can be designed in such a way that the indentations 28 are formed through it, which are located on the back of the handle or in the area of the inside of the hand, these indentations preferably extending from the mold seams that result during injection molding the separating seams are weakened. Different inscriptions or trademarks can also be incorporated into the insert 66, e.g. B. the word "Unigrip", as can be seen in FIG. Incorporating such designations in the vicinity of the mold parting lines would normally cause difficulties in the manufacture of the mold, at least it would not be useful. However, since these inscriptions are attached to the insert, the removal of the injection-molded handle after it has been lifted out of the injection mold can be carried out separately in the area of the inscription, in that the insert is removed from the lifted-out handle. If necessary, the insert can easily be exchanged for another insert provided with another different inscription, in order to
