DETAILED DESCRIPTION

[0031] The principles of the present invention apply particularly well to its application as a training aid for downhill (or Alpine) skiing. The instructional device allows for both the student and the instructor to have full visibility both downhill and to the sides. Turning to FIG. 1, with the instructional device 10, the instructor skis to the side and behind the skier (best seen in FIG. 2). The rounded extension member 17 of the device 10 fits passively around the student skier's midsection and provides proper ergonomics, stability and balance for the student as well as the instructor. With this positioning, the arms of the student are completely free—thereby assisting the student in learning and gaining balance.

[0032] Once proper balance has been achieved by the student, two easily removed and replaced handles 21 (best seen in FIGS. 4a and 4b) can be attached to the extension member 17. The detachable handles 21 serve two purposes. First, the device can be easily converted for use either from the student's right side or left side, depending on the instructor's preference. Second, the handles 21 can be added as the student progresses to help correctly position the student's hands and develop good posture for the eventual use of ski poles.

[0033] Utilizing the device 10, the instructor has total control of the skier's speed, which gives the student a significant sense of security and assists in gaining balance and positioning of the skis in both wedge (slowing and stopping) and parallel (for increased speed) situations.

[0034] As the student progresses further, the device 10 can easily be pulled away from the student while skiing. This creates a situation where they are allowed to ski freely and unencumbered. Alternatively, the device 10 can be readily replaced back around the student midsection should there be a loss of control, another skier or obstacle creates a situation requiring additional control and/or some other situation arises where there is a need to prevent possibility of injury.

[0035] Still referring to FIG. 1, a device 10 constructed in accordance with the principles of the present invention will be described in more detail. The device 10 includes a shaft 11 having a proximal end 12 and a distal end 13 (i.e., proximal and distal from an instructor when in use). The device further includes one or more instructor handles 14, 15 for an instructor to grasp.

[0036] First, an optional and/or removable handle or grip may be attached to the shaft 11 at the proximal end 12 at void 14. The handle is preferably similar to the handles 21 shown in FIGS. 4a and 4b. However, it will be appreciated that handles with differing geometries and structures may be provided. If the optional handle is not included or has been removed, then the instructor may grasp the proximal end 12 of the shaft 11. A knob or enlarged section (e.g., similar to the knob on a baseball bat)(not shown) may also be located at the proximal end 12 to help the instructor grip the device 12.

[0037] Second handle 15 is for the instructor's use and is mounted on the shaft between the midsection of the shaft 11 (indicated at dotted line 16) and proximal end 12 of the shaft 11. Handle 15 may be integrally formed with the shaft 11, may be secured with a fitting (e.g., as shown in FIGS. 7a and 7b), or may be affixed thereto (e.g., with glue, screws, tape, etc.). As shown in FIGS. 7a and 7b, a friction fitting 25 may be used with a securing member 26 that brings the fitting 25 into a tight engagement with the shaft 11. It will be appreciated by those of skill in the art that in this arrangement a fitting 25 is located at each end of the second handle 15. An advantage of this arrangement is that the second handle 15 may then be moved up and down the shaft 11 to accommodate different size and height students—as well as the comfort and preference of the instructor.

[0038] Extension member 17 is located at the distal end 13 of shaft 11. Extension member 17 includes an outward facing surface 19 and an inward facing surface 18. The inward facing surface is arranged and configured to be placed on or around the midsection of a student skier. Accordingly, a rounded surface 18 will generally provide a more comfortable surface area to engage the student's midsection and spread the forces (e.g., created when slowing a student skier) over a larger area. However, other inward facing surfaces 18 may also be used. For example, straight, diagonal and two surfaces coming together at an oblique angle might be used for surface 18.

[0039] Referring to FIG. 6, a diagrammatic view illustrating the angle α formed by the mean axis 28 of the shaft 11 and the mean axis 27 of the extension member 17 is provided. The mean axis 28 of the shaft is generally formed by the longitudinal axis of the shaft 11. However, the shaft 11 may include curves in some embodiments. The angle α is preferably an oblique angle. However, a right angle may also be used. An acute angle may tend to create a pinch point between the inward facing surface 18 and the midsection of the student. However, the principles of the invention may still be practiced with such an arrangement.

[0040] Referring now to FIGS. 1, 4A and 4B, in some embodiments extension member 17 may include voids 20 in which removable student handles 21 may be selectively inserted and affixed. In one embodiment, handles 21 include a screw, channel lock, or keyhole element which extends through extension member 17. Complementary corresponding elements 22 have a suitable thread or other device to secure the handles 21. The handles 21 preferably include a diameter and length that is sized for the student. Accordingly, in some embodiments, different size handles 21 may be utilized depending on the student. FIG. 5 illustrates the handles 21 in place with a child student skier grasping the same.

[0041] In a preferred embodiment, the various components of the device 10 are constructed of molded or injectable plastic. However, wood, aluminum, and other materials might be used. A design consideration for some embodiments of device 10 is that it will generally be used in cold weather. Accordingly, wood and plastic may be preferred due to heat transfer and comfort to the instructor. Another design consideration is that the device 10 is preferably constructed of a material that has a strength and rigidity for proper ergonomics, stability and balance for both the instructor and student. Further, preferably all edges, handles, extensions etc. are chamfered or rounded to eliminate sharp edges.

[0042] In use, the device 10 may help with at least three major components useful for students to learn when beginning downhill alpine skiing. Learning these three components help the student gain control and essential mastery of their skis. Balance is the critical and necessary first step followed by weight transfer and confidence. The present device 10 provides a device and method to address each component. It is anticipated that students of various physical abilities may be taught using the device 10. Accordingly, while the term “mastery of their skis” is mentioned, it is recognized that for some students, the outcome may be competence, enjoyment, and/or a new experience.

[0043] According to some embodiments, a method employing the training device 10 may be used to advance a student through a progression of the three components described in the preceding paragraph. The method is illustrated in FIG. 8 generally at 800 and begins at 801.

[0044] Early balance, and then confidence, is achieved by allowing the student to grasp and hold the extension member 17 (as shown in FIG. 2). It allows the student to easily stand while sliding their skis. By doing so, acquiring the necessary balance is facilitated while the student's speed is completely controlled by the instructor. This initial step is reflected at block 802.

[0045] Once early balance (and the fear of falling or going too fast is achieved), the student can begin to utilize their arms by letting go of the extension member 17 and allowing it to passively rest against the midsection (as shown in FIG. 3). At this step, the student advances their sense of balance. This further allows the student to confidently focus and learn proper body and ski positioning—as well as the weight distribution and transfer necessary for the sliding and gliding motion of the skis. All of which is necessary for turning, speed control and stopping techniques. This second step is reflected at block 803.

[0046] As skills and confidence are achieved using the device 10, the instructor can selectively employ the device 10 against the midsection of the student and/or control the pressure against the midsection as needed. This step is reflected at block 804.

[0047] Further at block 805, as the student continues to gain skills and confidence, the removable handles 21 on the extension member can be added (as shown in FIG. 5), to simulate the proper body and hand positioning for the future utilization of ski poles. This step is reflected at block 805 of FIG. 8. The method ends at 806. It will be appreciated that the method as described herein does not require that the steps recited in FIG. 8 need to be performed in a sequential sequence.

[0048] Referring next to FIG. 9, an alternative embodiment of the ski training aid device 10 is illustrated. The alternative embodiment device is illustrated generally at 10′. The device 10′ includes an instructor handle 15′ between proximal end 12 and distal end 13 of shaft 11′. Extension member 17′ is connected at distal end 13. Two foldable handles 21′ are cooperatively connected to the extension member 17′.

[0049] The shaft 11′ may be constructed with aluminum, with the remaining elements of the alternative embodiment device 10′ constructed of injected or molded plastic. However, other materials may be used as discussed above in connection with device 10. Also, one design choice which may be advantageous is to select materials and/or material colors such that the device 10′ is visible if dropped or left lying on the snow (e.g., a color that is visible when lying on white snow). The alternative embodiment device 10′ operates substantially in the manner described above in connection with device 10. However, some structural differences exist, including the rotation of the student handles 21′ and the instructor handle 15′ connection to shaft 11′ as will be described in the following paragraphs.

[0050] Now referring to FIG. 10, a perspective view of the extension member 17′ is illustrated. Connector 53 connects with shaft 11′. In the event that the extension member 17′ and shaft 11′ are not of unitary construction, such connection may be made by adhesive, compression fit, barbed or press fit engagement, and/or screws, among other connection methods. Extension member 17′ includes an outward facing surface 19′ and an inward facing surface 18′. Voids 51 are formed in the extension member 17′ to create spaces into which handles 21′ may be rotated when not in use (best seen in FIGS. 9 and 11). Slots 52 are provided within the voids 51 and into which rotational axes of the handles 21′ are located.

[0051] FIG. 11 illustrates the rotation of handle 21′ up out of the mean plane formed by extension member 17′ and to within the void 51, the void 51 being located generally within the mean plane formed by extension member 17′, along path of rotation 56. Each of the handles 21′ may optionally be rotatable into an up out of the mean plane position on either side of the mean plane formed by the extension member 17′. In some embodiments, an axis member is included on either side of handle 21′ and extends through the slots 52. The axis member extends into a member such as a friction fit member that can take a circular, some portion of a circle or horseshoe shape (not shown) which is located beneath member cover 54. The member cover 54 engages with a complementary cover on the other face of extension member 17′. The pair of member covers 54 are sized to engage with the member to provide enough friction that the handles 21′ remain in the desired position. Alternatively, a detent may be used to maintain the desired position. The bushing cover 54 and its complement are connected with screws 55 or other fastening devices. Optionally, the member may take the form of a bushing or bearing element.

[0052] Turning to FIG. 12, an alternative instructor handle 15′ is illustrated. The handle 15′ engages with shaft 11′. The handle includes a body 57 having a void 61 through which shaft 11′ is inserted. Accordingly, the external portion of shaft 11′ engages with the internal surface 60 of body 57. The handle 15′ may be affixed to the shaft 11′ or may be adjustable. In the case of being affixed, any number of known methods including adhesive, screws, set screws, etc. may be used. In the case of being adjustable, set screws, detents, significant friction engagement and other methods may be employed.

[0053] In view of the foregoing, it will be appreciated that the principles of this invention apply to a method and apparatus for downhill ski training. While particular embodiments of the invention have been described with respect to its application, it will be understood by those skilled in the art that the invention is not limited by such application or embodiment or the particular components disclosed and described herein. Further while the description refers to the device 10 being placed against the student's midsection, it will be appreciated that such description is approximate and that the device in practice may actually be placed above (ribs) or below (pelvis) the midsection of the student without departing from the principles of the present invention.

[0054] Accordingly, other components that embody the principles of this invention can be configured within the spirit and intent of this invention. The arrangement described herein is provided as only one example of an embodiment that incorporates and practices the principles of this invention. Other modifications and alterations are well within the knowledge of those skilled in the art and are to be included within the broad scope of the appended claims.
