SNOW SKI AND SKATE BOARD PLATFORM COMBINATION

Abstract

An apparatus that secures a skateboard platform to a snow ski with a base that has a sliding member and stationary member. An adjustment mechanism urges the sliding member to move toward or away from the stationary member. A stabilizer is movable toward and way from the sliding member via a guide path in the base. The stabilizer has two components that move one inside the other to lengthen or shorten a distance between their respective ends. The sliding member has a protruding portion that fits into a front snow ski binding. The stationary member snaps into the rear snow ski binding. The front binding is sandwiched between the stabilizer and the sliding member.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to an apparatus that is used as a skateboard and, more particularly, to a snow ski device that operates like a skateboard on snow surfaces.

2. Description of the Related Art

As mentioned in U.S. Pat. No. 4,116,455:

Skateboards are generally used on smooth, flat surfaces so as to allow for better riding by easy acceptability of the wheels that are part of the device. However, at this time the skateboard is restricted in its use—not only to the type of surface of the ground area but also by weather conditions. That is, during the winter months, in areas that have snow conditions the ground surfaces become covered and a skateboard cannot be operated.

As mentioned in U.S. Pat. No. 7,581,735:

In the area of skateboarding, skateboarders have traditionally had to turn to snowboards to have similar recreation in the snowy weather. Snowboarding, however, varies in many significant ways from skateboarding. The most obvious difference is the fact that a snowboarder's feet are bound and attached through boots to the snowboard, whereas, on a skateboard, the rider's feet are merely placed on top of the deck of the skateboard and are easily freed from the board to perform tricks and to discontinue the use of the board. Another significant difference is the feel and handling of the snowboard compared to a skateboard due to the fact that the skateboard has wheels and a truck between the deck and the ground that allows for steering and control while a snowboard's deck comes in direct contact with the ground. The locked-in feet and lack of suspension/steering ability make snowboarding a related, but different skill than skateboarding. Another feature of snowboarding and skiing is that both are edging devices.

A bideck snowskate has a top skateboard deck, which the rider stands on, and a lower ski deck, which is in contact with the snow. Bidecks come in single blade varieties and multiple blade varieties. Different bidecks are tailored to a different style of riding. Longer bidecks are favored for mountain snowskating, and shorter bidecks are favored for tricks and stunts.

What is needed is a way to slide across snow on a snow ski while standing upon a skateboard platform (or deck) so as to retain the same freedom of feet movement that the user experiences when skateboarding on pavement, yet retaining the same ski shoe binding settings that the user needs for skiing with the snow skis separate from the skateboard platform.

SUMMARY OF THE INVENTION

One aspect of the invention is to provide a ski board that is adjustable to fit any conventional ski binding without having to alter the ski binding settings. An adjustment screw is provided to allow the user to adjust the base of the ski board to fit in the existing ski binding.

Another aspect is to provide for a stabilizer, which is located in the front of the ski board. The stabilizer is adjustable in that it screws down to stabilize the front of the ski board so that when the rider applies pressure or weight at the front of the ski board, the stabilizer will not allow the ski bindings to eject the ski board even though the ski binds are designed to eject the ski boot when a ski applies too much weight or presser to the front of the binding. The ski board stabilizer also adjusts forward and back to accommodate larger and smaller bindings.

An additional aspect is to provide a tether system that will keep the ski board from sliding away on its own down a hill when the rider comes off the ski board.

A further aspect is to equip the ski board with a brake system. This brake system engages while the rider is not applying pressure or weight to the front of the ski board. When the rider is not standing on the ski board, the brake system engages and holds the ski board in place. This will also engage if the rider comes off the ski board. The ski boarder could also gradually lift their front leg (decreasing downward pressure) as they ride to engage the ski board break.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning to the drawings, FIG. 1 shows the ski board unit 10 of the present invention that allows one to ride a snow ski like a skateboard. Leaning from side to side turns the ski just like a skateboard. Leaning from side to side allows the ski to use its edges to turn like it was designed to do. FIG. 7 shows an exploded view.

The components of the ski board unit 10 include a skateboard platform 12, a base having an upper base part 14 and having a lower base part with a sliding portion 16 and a stationary portion 18, an adjustment screw 20 and a stabilizer 26. The adjustment screw extends across a gap 22 between the sliding portion 16 and the stationary portion 18 and into each of the sliding portion 16 and the stationary portion 18 to adjust the sliding movement of the sliding portion 16 towards and away from the stationary portion 18. The stabilizer 26 provides stability by preventing ejection of the lower part of the base from the front and read ski bindings. A tether 28 may be provided to extend from the skateboard platform 12 to loop around the ankle of a person's leg.

That is, the tether 28 attaches to the ski board 10 and keeps the ski board from sliding away from the user on a slope when the user falls or gets off the board. The tether 28 can be attached to the user's leg or held in the user's hand as the user operates the ski board unit 10. The length of the tether can be adjusted based on comfort and preference.

The turned up two ends of the skateboard top of the ski board platform allow for better grip while riding. A ruff sand paper grip covers the top of the skateboard platform 12.

The upper base part 14 retains the lower base part so as to retain the sliding portion 16 in a sliding manner and the stationary portion 18 in a stationary manner. The upper base part 14 has a grooved fit with the lower base part that keeps both the sliding portion 16 and the stationary portion 18 connected, allowing the sliding portion 16 to slide to the appropriate size of the ski binding. The sliding portion 16 slides back and forth as necessary to adjust to larger bindings.

Turning to FIGS. 3A through 3F, the sliding portion 16 is slid forward or backward as needed to adjust to larger or smaller ski bindings. One or more threaded adjustment screws 20 enable the user to adjust the size of the base that locks into the ski binding. By turning the adjustment screw 20 or screws in either a clockwise or counterclockwise direction as appropriate, the sliding portion 16 may be moved towards or away from the stationary portion 18, thereby increasing or decreasing the size of the gap 22.

To help with setting the correct position of the sliding portion 16, the sole 32 of the ski boot 30 may be placed beneath the lower base part as shown to serve as a guide to slide the sliding portion 26 to a relative position. In so doing, the sliding portion 16 of the lower part of the base is adjusted to slide from a position in which the distance of the lower part of the base from end to end is shorter than the length of the ski boot sole to a position in which the distance of the lower part of the base from end to end (inclusive of the gap 22) is equal to the length of the ski boot sole 32.

Once the end to end distance of the lower base part matches the end to end distance of the sole 32 of the snow ski boot 30, then, as shown in FIG. 3C-3D, the sliding portion 16 and the stationary portion 18 are ready to be inserted into conventional front and rear ski bindings 34, 36 of the snow ski 24 in the manner shown. The lower part of the base snaps into the conventional front and rear bindings just like a ski boot 30 (of FIG. 3A, FIG. 3B) would. The lower part of base of the ski board unit 10 adjusts to fit different size ski bindings. Thereafter, the stabilizer 26 of FIG. 3E is adjusted as to exert pressure between the underside of the overhang 15 of the upper part 14 of the base and the topside of the snow ski 24.

The adjustment of the stabilizer 26 is carried out as shown in FIG. 3F by unscrewing the inner cylinder 35 from the cylinder 40 until the hinged trapezoidal end piece 39 exerts pressure on the topside of the snow ski 24. Preferably, the base has a 4-inch height, which allows clearance of the ski binding and the skateboard platform 12.

Although not shown in FIGS. 1, 2, 3A and 3B, there are two sets of four threaded screws 38 of FIG. 7 that allow the user to secure the skateboard platform 12 to the base 14. As shown in FIG. 7 and understood from FIGS. 3G and 3H, the base has predrilled holes that align with the two sets of four threaded screws 38 of FIG. 7. If desired, additional pairs of such holes may be provided in the base 14 to enable the placement of the skateboard platform 12 to be adjusted forwards or backwards on the top of the base 14 to align the threaded screws 38 with the desired pairs of holes to make securement. Thus, the threaded screws 38 enable the user to adjust where the base that locks into the ski binding 34, 36 relative to the skateboard platform 12, which may enable the ski board unit 10 to be used with different size ski bindings. Although the embodiment of FIGS. 3C-3F has two pairs of threaded screws 38 (only two visible on side), preferably four pairs of threaded screws 38 as shown in FIG. 7 are used to provide stronger securement than can be provided by just two pairs of threaded screws 138.

The two sets of four screws generally correspond with the placement of two sets of four holes conventionally used to secure a support for a pair of wheels to the underside of a skateboard. The base 14 is provided with eight predrilled holes in its top surface to align with the two sets of four threaded adjustment screws 138. However additional pairs of predrilled holes may be provided in the base 14 to enable some adjustment as concerns the relative placement of the skateboard platform 12 on the base 14 by aligning the threaded adjustment screws 138 with desired pairs of holes in the base. The ski board in accordance with the invention may be assembled into an operative condition by following six steps (See FIGS. 3A-3F):

Step 1. Use a screwdriver to turn the adjustment screw to adjust the movable sliding portion 16 of the ski board base to match the size of the bottom or sole 32 of the ski boot 30 used for the ski one plans to use the ski board with. Turn the adjustment screw 20 counterclockwise to make the effective size of the base larger and clockwise to make smaller.

Step 2. Turn the adjustment screw 20 to adjust the movable sliding portion 16 of the ski board base to match the size of the bottom or sole 32 of the ski boot. Stop when there is a match.

Step 3. Line up the Ski board base like one would for one's ski boot 30 with the front tip of the ski board base going into the front part of the ski binding. Line up with nose/front of base first.

Step 4. Line up the Ski board base to the ski binding and just like one would with one's ski boots, putting the front of the ski boot into the front part of the ski binding and then push down on the back to snap the ski board base into the ski bindings.

Step 5. Use one's hand to twist the ski board stabilizer 26 to extend the stabilizer 26 to fit snug against the ski 24. The ski board stabilizer 26 is threaded 35, 40 and telescopic. As one twists the lower part of the stabilizer 26, it will extend down toward the ski 24.

Step 6. Once one has twisted the ski board stabilizer 26 to extend the stabilizer 26 to fit snug against the ski. It is now ready to start using the ski board on the snow.

Turning to FIGS. 3F and 3G, provision may be made to enable the stationary portion 18 to instead slide back and forth to fit larger bindings. As shown, the stationary portion 18 may be repositioned into any one of a plurality of different positions by choosing which group of two pairs of holes 17 in the upper part 14 of the base should align with four holes through the stationary portion 18 to secure the screws 19 accordingly. The sliding portion 16 may be slid and secured as in the other embodiments.

Turning to FIGS. 3I and 3J, a small weight 120 (e.g., one ounce) may be applied to one side of the base or clipped onto the platform one side and then tightened with a screw 122 to keep the small weight 120 in place. That way, should the user get off the ski board unit 10, the ski board unit 10 will likely tip over on the side of the weight, thereby preventing the ski board unit 10 from sliding away down a hill. Such a small weight applied to one side does not completely replace the functions of the brake since the ski board unit 10 will not remain upright for long since the weight is present, which means that the ski board unit 10 will not be held steady while the user is trying to step on the ski board unit 10. Further, the user is not able to gradually slow down the ski board unit 10 since there would be no brake of FIGS. 6A and 6B to apply. In its simplest form, the small weight could be a conventional one-ounce line clip weight whose bottom is tightened by turning the screw 122 to secure to one side of the platform.

The significance of the stabilizer 26 can be better appreciated by turning to FIG. 4 which illustrates what may happen in its absence or if not secured properly to exert pressure on the topside of the snow ski 24. That is, the person using the ski board unit 10 applies a weight force forward, which triggers the ski bindings to eject the sliding portion 15 and the stationary portion 18 of the lower part of the base. Indeed, the forward weight of the platform 12 itself may be enough to trigger the bindings to eject the base.

Turning to FIG. 5A, the stabilizer 26 keeps the ski board 10 from ejecting when the rider applies their weight to the front of the ski board 10. The user does not have to adjust the ski binding tension to keep the ski board 10 from being ejected. It is safer not to adjust the ski binding tension, because it is set for the user's height, weight and ability. The user would want the ski binding to eject based on these factors when the user is skiing with the skis (without the board attached to a ski). The ski board 10 allows the user to use the existing skis at their current settings. It is easy to snap in and set and also easy to disengage the board from the ski.

A ski board stabilizer channel allows the stabilizer 26 to adjust toward and away from the binding. This allows the ski board unit 10 to adjust to different size bindings. The cylinder 35 goes inside cylinder 40. They are threaded and adjusted by twisting cylinder 35. Screw down to ‘tighten’ (i.e., shorten the overall length) and unscrew to ‘loosen’ (i.e., increase the overall length). There is a swivel part 41 attached to the bottom of the inside cylinder 40 to which is hinged a trapezoidal end piece 39.

By unscrewing the engaged threads of the cylinder 35 and the inside cylinder 40, the hinged trapezoidal end piece 39 rotates as need be to rotate so that the bottom of the hinged trapezoidal end piece 39 rests flat upon the incline of the snow ski 24. The stabilizer 26 provides front weight stability and keeps the bindings 34, 36 from ejecting upon the application of front weight pressure.

Upon screwing the engaging threads of the cylinder 40 and the inside cylinder 35, their end-to-end distance of them shortens and upon unscrewing the engaging threads of the cylinder 40 and inside cylinder, their end-to-end distance lengthens.

A channel pin 42 fits in selected one of grooves 44 of the grooved track to help secure the ski board stabilizer 26. The channel pin 42 presses into the selected one of the grooves 44 as the cylinder 40 and inside cylinder 35 are unscrewed sufficiently with end of the inside cylinder 35 pressing against a topside surface of the snow ski 24. A channel cap 47 is screwed in place into the overhang of the base 14 with screws 43 to keep the channel pin 42 fitted into position to the selected groove 44. By loosening the screws 43 and thereby the channel cap 47 from the overhang, the channel pin 42 may be relocated to a different groove 44 and thus the stabilizer 26 may be relocated accordingly.

FIG. 5B is an alternative embodiment for the stabilizer to that of FIG. 5A in which the pin and grooved track of FIG. 5A are replaced by two rows of teeth 45A, 45B that engage and mesh with each other as the inside cylinder 35 is rotated counterclockwise relative to the cylinder 40 by a sufficient amount such that pressure is applied via the hinged trapezoidal end piece 39 to the topside of the snow ski 24. The row of teeth 45A is directed downwardly from the underside of the overhang 15 of the upper part 14 of the base.

When the inside cylinder 35 is rotated clockwise relative to the cylinder 40, pressure is released and the cylinder 40 and inside cylinder 35 may be displaced in a linear direction with the hinged trapezoidal piece 39 and one of the rows of teeth 45A closer to or further away from the sliding portion 16. The channel cap 47 has a center region that is open to accommodate the cylinder 40 being moved laterally to any position in which the two rows of teeth 45A, 45B may engage and mesh with each other. The channel cap 47 is secured to the underside of the overhang 15 of the upper part 14 of the base with screws 43.

FIG. 5C is a further embodiment of the stabilizer in that a series of pre-drilled threaded holes 49 are made in the underside of the overhang 15 of the upper part 14 of the base into which screws 43 are aligned and fastened to secure the channel cap 47 in place to allow the cylinder 40 to press against the underside of the overhang 15 as the hinged trapezoidal end piece 39 presses against the topside of the snow ski 39 that arises from unscrewing the inside cylinder 35 relative to the cylinder 40.

FIG. 5D is yet another embodiment of the stabilizer in which a magnetic strip 51 is provided on the underside of the overhang of the base and a further magnet 53 is provided atop the cylinder 40 of the stabilizer to magnetically attract with the magnetic strip 51. The magnetic force should be strong enough to support the weight of the stabilizer dangling from the overhang 15 of the upper part 14 of the base as the internal cylinder 35 is being rotated until the hinged trapezoidal end piece 39 exerts pressure upon the topside of the snow ski 24.

FIG. 4 shows that without the stabilizer 26, the application of forward weight would tend to trigger the bindings to eject the base from the bindings.

Turning to FIG. 6A, a brake 50 holds the ski board unit 10 in place until the user is fully on the ski board unit 10 with both feet. The platform 12 has a forward portion 13 that is hinged to the rest of the platform at a hinge 11. The base 14, which has the overhang 15, also has a raised portion adjacent the overhang 15 so as to enable the brake seat 52 to fit in a recess alongside the stepped end of the raised portion and be above the overhang 15.

When the user applies weight to the front of the ski board and depresses the brake seat 52, the arm 54 pivots about pivot 55 so that the brake seat 52 disengages from its brake position to enter into a non-braking position of FIG. 6B. As the pivoting commences, a rod 59 at the end of the arm 54 slides within an open track 57 in the brake seat 52 in response to the pivoting force exerted about the pivot 55 by depressing the brake seat 52.

When the user removes their feet from the forward portion 13 of the platform 12, the forward portion of the arm 54 lowers because of pivoting movement about the pivot 55 under spring tension from spring 61 in or on lever arm 63 so that the brake seat 52 returns to the activated brake position of FIG. 6A.

When deployed, the arm 54 pivots to stop the ski board unit 10 from sliding forward. When weight is put on the front of the ski board unit 10, the brake mechanism is depressed and the arm retracts/disengages. The tension spring 61 lifts up the brake seat 52 when the user's weight has been lifted and deploys the arm 54 to stop the ski board 10 from sliding forward. FIGS. 6C-6E show how to activate, deactivate and reactivate the brake 50 merely by pressing down with one's foot onto the forward portion 13 of the platform to deactivate the brake and thereafter removing one's foot from pressing down to allow the spring tension to restore the brake to the activated position.

FIGS. 6F and 6G correspond to the views of FIGS. 6A and 6B, but for a different embodiment in that the hinged front portion 13 of FIGS. 6A and 6B is omitted so that the platform 12 is a single piece and not hinged into two portions. In addition, a rear support 73 is provided underneath a rear portion of the platform in the vicinity of the platform 12 where a hole or holes to secure a conventional skateboard wheel or wheels is/are provided. The rear support 73 is pivoted to the topside of the base 12 with a pivot 75. The underside of the platform 12 is secured to the rear support 73 by one or more screws. The underside of the platform 12 is also secured to the brake seat 52.

An advantage of the brake of FIGS. 6A and 6B over that of the brake of FIGS. 6F and 6G is the ability for the user to apply the brake gradually as the ski board unit 10 is in motion to slow the ski board unit. On the other hand, the brake of FIGS. 6F and 6G has an advantage over that of the brake of FIGS. 6A and 6B in that any conventional skateboard platform may be used without any need to modify the skateboard itself. Such is not the case for the brake of FIGS. 6A and 6B because the skateboard may need to be split into two parts that are then hinge to each other.

However, the brake of FIGS. 6A and 6B and the brake of FIGS. 6F and 6G offer the ability of keeping the ski board unit 10 steady and secure when left on a hill incline to enable the user to step on the platform for use of the ski board unit.

Also, both prevent the ski board unit from sliding down a hill on its own since the lever arms are spring loaded to push against the ground.

All components of the base of the ski board unit may be fastened to each other and to the underside of the platform by conventional fastening techniques, such as with fasteners (screws in screw-threaded holes). Pivots and hinges of the brake or below the rear support may be secured to the base in any conventional manner that permits pivoting about the pivot and rotation about the hinges.

While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the scope of the present invention.

The method of claim 14, further comprising: providing a brake having a brake seat, a lever arm and a spring arm;pivotally connecting the lever to the base, the brake seat having two slots, the lever arm having an lever arm end with a rod that slides back and forth in one of the two slots, the spring arm having an spring arm end with a further rod that slides back an forth in a remaining one of the two slots, the spring arm including a tension spring with a spring bias that tends to elevate the brake seat away from the base and impart a force on the lever arm that pivots the lever arm in a clockwise direction into a deployed position, the brake seat moving into a recess of the base in response to exertion of a manual force from above to depress the brake seat to cause the lever arm to pivot in a counterclockwise direction into a non-deployed position.

21. The method of claim 20, further comprising: securing a support to an underside of a platform closer to a rear of the platform than to a front of the platform;securing the brake seat to the underside of the platform closer to the front of the platform than to the rear of the platform so that the brake seat and the support are spaced apart; andpivoting the support relative to the base and thereby moving the platform between two positions, with the brake seat being elevated away from the base in one of the two positions and the brake seat being closer to the base in the other of the two positions, the lever being urged into the deployed position with the brake seat in the one of the two positions with the brake seat elevated away from the base and the lever arm being in the non-deployed position with the brake seat in the other of the two positions and closer to the base.

22. The method of claim 14, further comprising: turning an adjustment screw of the adjuster to adjust the sliding portion until an end to end dimension of the base matches an end to end dimension of the bottom of a ski boot, wherein the turning of the adjustment screw changes the end to end dimension of the base;inserting a portion of the sliding portion into a front ski binding of the snow ski;pushing down on a rear portion of the base to snap the rear portion of the base into a rear ski binding of the snow ski; andtwisting at least one component of the stabilizer to extend the stabilizer to fit in an abutting manner against the snow ski.

23. The method of claim 15, further comprising: securing a tether to the skateboard platform.

24. The method of claim 15, further comprising: securing a weight to one side of the skateboard platform that causes the skateboard platform to topple from the one side in an absence of a counterbalancing force.

25. The method of claim 14, wherein the at least one sliding member includes two sliding members that are configured slide toward and away from each other, the base including a further base member to which the two sliding members are held to slide back and forth relative to the further base member, and further comprising: securing the two sliding members into respective relative positions adjacent the further base member.

26. The method of claim 25, further comprising securing a skateboard platform to the further base member, holding the two sliding members with bindings of a snow ski so that the sliding members and the further base member collectively are between the skateboard platform and the snow ski.
