The detachable chair lift leg rest can be assembled with the ski pole shaft 11 and ski boots 18 prior to purchase of the products, or it can be a sold as an after-market kit which the skier can use on their existing equipment.

    (18) As shown in FIGS. 1-15, the detachable leg rest of the present disclosure includes a first engagement member 12 and a second engagement member 14, both of which may be removably secured to a ski pole 10 having a shaft 11 including a proximal end (“P”) and distal end (“D”) during use. The detachable leg rest also includes a hanger 20, which may be formed as a loop 30, or a strap 24, which may be permanently or removably secured to the ski boot. The hanger 20 is constructed and arranged so that it has a hanger opening 21 to receive an engagement member. The hanger opening 21 is defined by the hanger body 19. The proximal end of the shaft 11 of the ski pole 10 includes a grip 36 and the distal end includes a basket 34, as is conventional. In use, the first, proximal, or upper engagement member 12 may be secured to the shaft between a mid and upper portion of the shaft, depending upon the size of the user and the chairlift. The mid to upper portion of the shaft is that portion of the shaft extending from approximately the mid-point of the shaft to the proximal end of the shaft below the grip 36. The proximal engagement member 12 is used to engage the ski pole 10 with the bar 38 of the chair lift 26 and should be positioned accordingly along the shaft for hanging engagement of the ski pole. The lower engagement member 14 may be secured to the distal end of the shaft, below the mid-point of the shaft 11 and above the basket 34. The second, distal, or lower engagement member 14 is used to removably engage the pole with the ski boot 18 by engaging the hanger 20 through the hanger opening 21. Positioning of the lower engagement member 14 sufficiently above the basket to not cause interference by the basket is recommended.

    (19) One embodiment of a detachable chair lift leg rest is illustrated in FIG. 1. As shown in FIG. 1, the shaft 11 of a ski pole 10 includes lower engagement member 14, which may be a hook or other similar device, and an upper engagement member 12, which may also be a hook or the like, as would be known to one of skill in the art. The upper engagement member 12 and the lower engagement member 14 can be adjusted to allow the device to be used by skiers of any height. The upper engagement member 12 and lower engagement member 14 may be made of a lightweight material such as high-density polyethylene, or the like, as known to those skilled in the art. The present embodiment of the upper and lower engagement members 12, 14 show an arcuate shape with rounded edges to avoid snagging on the skiers clothing but may be have other shapes and finishes, as would also be known to those of skill in the art, provided that they removably engage the chairlift bar and ski boot as described herein below.

    (20) The upper and lower engagement members 12, 14, as best shown in FIGS. 4-9, each include a body 40 having an opening 15 sized to receive the shaft 11 of the pole therein so as to grip the shaft 11. The body 40 includes an attachment portion 31 to secure each of the engagement members 12, 14 to the shaft 11, for example by a locking member 32. The locking member 32 may be placed and secured at the correct height, as determined by the length of the skier's legs relative to the safety bar of the ski lift. The locking member 32 may be a self-clamping sex bolt, or the like designed to tighten and secure the attachment member in a clamping manner, as would be known to those of skill in the art. The locking member 32 may be recessed into the upper and lower engagement members 12, 14 in order to minimize the risk of injury or catching on clothing. In order to allow the upper and lower engagement members 12, 14 to fit on any circumference of ski pole 10, a bushing 16 may be inserted into the opening, as desired, 15 to create a more secure connection between the upper and lower engagement members 12, 14 and the shaft 11, as needed. The bushing 16, as are conventional and would be known to those of skill in the art, are available in a variety of thicknesses and, in addition to allowing a fit on any brand or size of pole, allow for a more secure friction fit on the ski pole 10 on any section of the shaft 11, regardless of where on the taper of the shaft 11 the skier 28 attaches the engagement member. In the embodiment shown in FIG. 4, the body 40 of the upper engagement member 12 has an arcuate indent whose size and geometry allows for engaging, latching, or resting the on the restraint bar 38. Alternately, other geometric shapes may be utilized, as would be known to those of skill in the art.

    (21) Referring now to FIG. 5, the body 40 of the lower engagement member 14 may also include an arcuate indent whose size and geometry allows for hooking, grabbing, or clasping the hanger 20. As illustrated and described above, the shaft 11 is inserted into the opening 15 of the lower engagement member 14, through a bushing 16, and the lower engagement member 14 is secured to the ski pole shaft 11 by the locking member 32. While the current illustrations show the upper engagement member 12 and the lower engagement member 14 as similar shapes and designs, the upper engagement member 12 and the lower engagement member 14 do not have to be the same, and each can have a different shape and geometry as would be understood by one of skill in the art.

    (22) Referring now to FIGS. 10-13 various embodiments of attaching the lower engagement member 14 to the ski boot 18 by a hanger will be shown and described. As shown in FIG. 10, one embodiment includes the hanger 20 being removably secured to the ski boot 18 by a fastener, such as boot bolt 22. The boot bolt 22 may be any variety of fastener including a variety of bolts, such as a split ring hanger 22a as illustrated in FIGS. 10-11, a vibration loop clamp 22b as illustrated in FIG. 12, or any other bolt or the like that would function to removably secure the hanger to the ski boot, as would be known to those of skill in the art. The boot bolt 22 is easy to adjust by the user, and can even be adjusted with gloved hands, so that before riding the lift, the skier can tighten the boot bolt 22 and turn the hanger perpendicular to the boot, allowing the lower engagement member 14 to be hooked onto the hanger 20 with ease, as best shown in FIG. 11.

    (23) Referring now to FIG. 12, another embodiment of the boot bolt is illustrated as a vibration loop clamp, which is also a conventional member known to those of skill in the art. In this embodiment, the same or similar elements of the embodiment of FIG. 1-11 are labeled with the same reference numbers proceeded with the numeral “1.” In this embodiment, the boot bolt 122b is used to secure the hanger approximately perpendicular to the ankle of the boot. The vibration loop clamp is coated with rubber and when secured, the hanger 120 is held in place by friction with the rubber. Thus a single adjustment of the hanger 120 is possible. The embodiment of FIG. 12 utilizing a vibration loop clamp operates in the same manner as the previous embodiment shown and described to engage the hanger 120 with the lower engagement member.

    (24) Referring now to FIG. 13, in another embodiment of the disclosure, the hanger 220 is removably affixed to the ski boot 218 by a strap 224. In this embodiment, the same or similar elements of the previous embodiment are labeled with the same reference number proceeded with the numeral “2.” The strap 224, as shown in FIG. 14, may be a stretchable ski strap or the like, provided around the ski boot. The strap allows the skier to removably secure the hanger 220 to the boot without drilling a hole into the ski boot as would be necessary to secure a bolt or the like. The strap is ideal for a skier who may be renting boots or otherwise cannot, or does not want to, permanently or semi-permanently change their ski boots. The strap can have a variety of configurations, thicknesses and lengths, and may be adjustable, as would be known to one of skill in the art. In the present embodiment, the hanger 220 is placed in a substantially vertical position by the skier to allow for the lower engagement member to attach to the hanger 220.

    (25) Referring now to FIG. 15, in another embodiment of the disclosure, the engagement member 314 is removably engaged with the tongue loop 330, that has been reinforced to support weight. In this embodiment, the same or similar elements of the previous embodiment of are labeled with the same reference numbers proceeded with the numeral “3.” The tongue loop 330 allows the skier to removably secure the hanger 320 to the boot without drilling a hole into the ski boot as would be necessary to secure a bolt or the like. The tongue loop 330 is often a component of commercially available ski boots 318 and is used for assisting the skier with putting the boot on. In this embodiment, the tongue loop 330 is reinforced which allows for the skier to us it in place of adding an additional bolt or strap to the boot. In the present embodiment, the skier engages the lower engagement member 314 directly with the tongue loop 330.

    (26) Use of the detachable chair lift leg rest will now be described with reference to the FIG. 1. Prior to boarding the ski lift, either at home or in the lodge, the skier would attach the upper engagement member and the lower engagement member 12, 14, to the shaft 11 of the ski pole 10. The skier positions the engagement members such that when the skier is in a seated position and holds the ski pole in front of them approximately parallel to their body, the upper engagement member 12 is positioned so that it can engage with the chair lift restraint bar (approximately four to eight inches above the knee, depending on the height of the skier), and the lower engagement member is positioned so that it is at the distal end of the ski pole and it can engage with the ski boot hanger 20. The body of each engagement member is positioned so that the arcuate portion of the body 40 is directed toward the body of the skier when the skier is holding the ski pole by its grip. If the strap 24 is used, the lower engagement member is positioned so that the arcuate portion of the body 40 is perpendicular to the skier. The skier also either permanently or removably affixes the hanger 20 to the ski boot 18 as shown by the embodiments above.

    (27) Once at the mountain, the skier simply loads the chair lift in the normal manner, and once in the seated position, lowers the restraint bar 38. The skier engages the ski boot to the lower portion of the pole by means of the hanger 20, tongue loop 30, etc. as described above. Once the lower engagement member 14 is engaged with the boot, and after the restraint bar 38 is lowered, the skier lifts their poles and engages the upper engagement member 12 with the restraint bar. When both the upper and lower engagement member 12, 14 are attached, the weight of the skier's legs, ski boots and skis is transferred through the ski pole 10 and onto the restraint bar 38. Once the lift reaches the top, the skier releases the upper engagement member 12 from the restraint bar 38 by lifting their poles and the upper engagement member up and away from the restraint bar, then releases the lower engagement member 14 from the hanger 20 by lowering the ski poles, lifts the restraint bar 38, and unloads in a normal manner. The skier can then continue down the mountain without any additional thought about the detachable chair lift leg rest until they get on the next lift.

    (28) It will be understood by those skilled in the art that various changes in the form and details may be made herein without departing from the spirit and scope of the invention as defined by the appended claims. For example, the materials disclosed herein may be readily changed, as may the dimensions and geometric configurations. The upper and lower engagement members and the strap may be made out of a variety of materials. The bolts referenced are defined by example only and may be any bolt or attachment member known to those of skill in the art such as split ring hangers, vibration loop clamps, clamps, screws, or the like. Any variety of ski poles, ski boots, and skis may be used. The hanger referenced and shown may be any type of hanger, loop, support, carabiner, hook, or the like, of any shape with any size opening defined by a body that can receive the engagement member and may be made of any material that can support the weight of the ski boots, skis and poles.
