Mitchell Attorney, Agent, or FirmHofgren, Wegner, Allen, Stellman &amp; McCord [57] ABSTRACT A strapless ski pole grip includes a generally cylindrical body having an axial bore for receiving the shaft of a ski pole. The ends of the cylindrical body have integrail fingers which project outwardly and sideways to press against a skiers hand between the hand knuckles and the first finger joints. The lateral extents of the fingers form rigid supporting platforms for the top and bottoms of a skiers hand. At least one finger is resilient and moves sideways when the ski pole becomes captured to allow sliding withdrawal of the skiers hand.  
 15 Claims, 5 Drawing Figures STRAPLESS SKI POLE GRIP BACKGROUND OF THE INVENTION This invention relates to a strapless ski pole grip which allows emergency release ofa skiers hand, while also providing sufficient support during normal skiing conditions.  
  When a ski pole becomes captured in use, as by the basket becoming snagged on an object, conventional retention straps will bind the skiers hand to the captured ski pole and &#39;may create a serious injury. To obviate this problem, strapless ski pole grips have been developed, such as shown in US. Pat. No. 3,479,045 to Miller. Such a strapless grip includes one or more projections which overlie a small portion of the skiers hand to provide support therefore.  
  Unfortunately, the projections of known strapless grips provide minimal retention characteristics and sudden. but not uncommon, forces may cause the skier to lose his grip and hence the ski pole. For example, in some ski conditions which create sticky snow, the normally smooth upward release of the ski pole tip out of the snow may be prevented, producing a jerk as the skier lifts his hand upwardly. Since strapless ski pole grips have an upper resilient finger with a substantial upward movement, the unexpected jerk may pull the ski pole out of the skier&#39;s hand.  
  To overcome these problems, some ski pole grips use a quick-release type strap which does not have to be looped around the skiers wrist. Generally, the strap extends across the length of the body of the grip and forms a channel for the skiers hand. For example, in US. Pat. No. 3,565,451 to Giambazi, the strap includes a buckle which tightens the strap against the skiers hand. between the hand knuckles and the first finger joints, sufficient to prevent inadvertent release of the ski pole. Unfortunately, the retention strap still binds the skiers hand to the ski pole and during some emergency situations, the skiers hand may not be released.  
 SUMMARY OF THE INVENTION In accordance with the present invention, an improved ski pole grip overcomes all of the above noted disadvantages of prior strapless grips and prior grips with quick-release type straps. For maximum safety in emergency situations, the retention strap is entirely eliminated. The grip uses a pair of projecting fingers which define a channel for retaining the skiers hand.  
 During use, the lateral portions of the fingers form rigid upper and lower platforms for supporting the top and bottom of the skiers hand, regardless of the pressures exerted parallel with the ski pole axis. During an emergency situation, in which the ski pole becomes captured, the body of the skier will continue to move until the skiers arm is outstretched. One of the fingers will then move sideways. opening the channel and allowing sliding release of the skiers hand. As a result, the ski pole grip provides for emergency release while also providing for rigid support in the axial direction along which normal skiing forces are exerted.  
  One object of this invention is the provision of a strapless ski pole grip which provides adequate support and retention of a skiers hand even though the skier relaxes his grip, and which releases the hand quickly in the event of an emergency situation.  
  Further objects and features of the invention will be apparent from the following description and from the drawings. While an illustrative embodiment of the invention is shown in the drawing and will be described in detail herein, the invention is susceptible of embodiment in many difierent forms and it should be understood that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated.

 DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, a strapless ski pole grip is illustrated which includes an elongated, generally cylindrical body 10 having an axial bore 12 for receiving the shaft 14 of a ski pole. The bore 12 extends along a substantial length of the body 10 and is coaxial with the ski pole shaft 14. Integral with body 10 and extending from the ends thereof are an upper projecting finger 20 and a lower projecting finger 22. As seen in FIG. 1, the pair of fingers 20 and 22 are located to press against the gloved fingers of a skiers hand 24, between the hand knuckles 26 and the first finger joints 28. The skier&#39;s thumb 30 extends around the opposite side of the body 10 to allow the skiers hand to firmly grasp the grip.  
  Upper projecting finger 20 has a relatively thick lateral section 34 which extends outward a sufficient distance to clear the gloved hand of the skier. At the end of the lateral section, the finger curves downwardly and forms an axial or side section 36 which extends parallel to and offset from the center axis of body 10. The axial section 36 preferably extends below the midpoint of the body 10, that is, the axial section 36 has a length greater than the majority of the length of the channel.  
  Lower projecting finger 22 has a relatively thick lateral section 38 which smoothly curves into an uptuned angulated section 40 which is spaced from side section 36 by a gap 46. The axis of side section 36 and the axis of angulated section 40 are coplanar and intersect the center axis of cylindrical body 10. The axis of side section 36 intersects the lower finger 22, and defines an open channel 50 generally located between the cylindrical body 10 and the side fingers 20. The width of the channel 50 is made approximately equal to the width of the gloved hand.  
  Along cylindrical body 10, a series of ridges 44, oval cross-section, define therebetween a series of valleys for receiving the four fingers of the skiers hand. When the skier is properly holding the grip, as seen in FIG. 1, the fingers 20 and 22 press against the skiers fingers between the hand knuckles 26 and the first finger joints 28. At this time, the major axis of the ridges 44 extends forwardly. As can be seen in FIGS. 3 and 4, the major axis of ridges 44 is approximately at a 45 angle with respect to the center axis of the fingers 20 and 22. The ski pole grip shown in FIGS. 1-5 is designed for the left hand of the skier, and it will be appreciated that a separate ski pole grip is provided for the right hand of a skier. In such a right hand grip, the fingers and 22 would also be at an angle of approximately 45 with a major axis of the ridges 44, but would be located on the opposite side of the major axisv The ski pole grip may be molded from PVC material having a durometer reading of approximately 75 to 85. The hardness and dimensions are selected so that the pair of fingers 20 and 22 are resilient, and the sections 36 and 40 can flex or bend. However, the lateral sections 34 and 38 are formed to be rigid in order to respectively define top and bottom platforms for supporting the skiers hand.  
  To grasp the ski pole, the skier inserts four fingers through the channel 50 and wraps his thumb around the opposite side of the body 10, as shown in FIG. 1. In this position, the inner surface of upper finger 20 presses gently against the skiers gloved fingers, between the hand knuckles 26 and the first finger joints 28. The pair of projecting fingers 20 and 22 form a retention system which maintains the ski pole in the skiers hand, even though he loosens his grip.  
  During an emergency situation, as when the ski pole becomes captured by an object, the skiers hand is pulled rearwardly, as the ski pole rotates about the shaft 14. The side section 36 of upper finger 20 is deflected to the side along a lateral axis 52, as seen in FIG. 5, opening the channel 50. This allows the skiers four fingers to readily slide out of the channel. The upper finger 20 is constructed to have a substantial side movement and little upward movement, to prevent inadvertent release under normal skiing conditions. Generally, sliding release of the hand will occur only when ski pole has been captured on an obstacle. For other conditions including large downward and upward pressures, the fingers 20 and 22 serve as rigid platforms which support the upper and lower sides of the skiers hand.  
  Various modifications may be made to the illustrated strapless ski pole grip, following the above teachings. Generally, the length of gap 46 is not critical. Preferably, the gap 46 should not be lengthened to an appreciable extent, as this would reduce the retention capabilities produced by the overlying finger 20. While the release finger 20 has been illustrated as being the upper finger, the positions of the upper and lower fingers could be reversed. As another modification, the upper finger 20 and the lower finger 22 could be made substantially the same length, and define therebetween a gap located at the mid-point of the ski grip. In such a case, both the upper and lower fingers would be used to press against the skiers hand.
