Abstract

An attachment that when added to a hard shelled snowboard binding converts the binding to a semi step-in binding. The step-in binding allows the rider to exit the ski lift chair with complete control because the rear boot can be placed and held in the rear binding rather than on the stomp pad which is normal in snowboarding.

The rider can lift their heel and step out of the rear binding when reaching the bottom of the incline and use the freed foot to push away from the drop off point.

Stepping into and locking the binding down is greatly facilitated when the rider is ready to make a run.

Description

This utility patent application is based on a provisional application filed on Jan. 1, 2001 and having Serial No. 60/266 103.[0001]

BACKGROUND OF THE INVENTION

(a) Field of the Invention

This invention relates to ski and snowboard bindings and more particularly, but not by way of limitation, to a snowboard hard shell boot binding attachment.

(b) Discussion of Prior Art

Snowboarding has been around since the mid-sixties but the sport didn't catch on or start to grow until the mid-eighties. This was when the two million or so skateboarders discovered they could strap a snowboard to their feet and do skateboard tricks on the snow rather than on concrete or wood. Almost every ski resort now features a skateboard park and pipe—they simply call it a snowboard park and pipe. Growth of the sport was rapid but it seemed to be pretty much restricted to skateboarders who use soft boots enabling them to perform skateboard tricks while using a snowboard. The problem with soft boots is that the center of gravity is 4 inches above the board when the rider is maneuvering.

Hard shelled boots and bindings correct this problem but present another problem when getting off the chair lift. Hard shelled boots have a hard plastic sole and provide very little traction when placing the rear boot on the stomp pad for balance when dismounting from the chair lift.

An attachment to the hard shelled boot binding solves this problem by allowing the rider to place their boot in the rear binding and have it held in place until reaching the bottom of the incline after exiting the chair. Snowboarders normally get off the ski lift chair with only the lead foot attached to the board. One foot must remain free so the rider can push over flat terrain since they do not use poles like skiers do. This attachment also greatly facilitates the locking down of the binding when the rider is ready to make a run. No prior art showed a way of stepping into a binding when exiting the chair lift while wearing a hard shelled (ski) boot.

SUMMARY OF THE INVENTION

In view of the foregoing, it is a primary object of the subject invention to provide a hard shelled boot binding attachment that will allow the rider of a board to be able to exit the ski lift chair under complete control by having both feet attached to the board.

Another object of the invention is to allow the rider to freely step out of the binding after exiting the chair lift and use the freed foot to push themselves to an area where they may wish to start a run.

Still another object of the invention is to allow the rider to reset the toe locking clip and step into the binding heel first, making sure the heel lug (extension) is inserted under the heel bale and lowering the toe of the boot so it engages the barrels on the toe clip causing the clip to rotate to a partially closed position. A slight additional tug on the cam locking toe clip locks it in place.

These and other objects of the present invention will become apparent to those familiar with ski bindings and binding for snowboards from the following detailed description, showing novel construction, combination and elements as herein described and more particularly defined by the appended claims, it being understood that changes in the precise embodiment to the herein disclosed invention are meant to be included as coming within the scope of the claims, except insofar as they may be precluded by the prior art.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate complete preferred embodiments of the present invention according to the best modes presently devised for the practical application of the principles thereof and in which: [0012]
FIG. 1 is a side view showing how the attachment is affixed to the binding caps, the bales and the cam lever locking clip. The sole of the boot is shown for clarity. Only one side of the binding attachment is shown because sides are alike. [0013]
FIG. 2 shows the toe of the boot inserted into the toe bale area of the attachment on the binding. [0014]
FIG. 3 shows how the rear bale locks the boot in but not down when the heel of the boot is lowered. [0015]

FIG. 4 shows the heel of the of the boot inserted under the heel bale while the toe locking clip is preset in the open position. Lowering the toe of the boot on the barrels causes the toe clip to rotate and partially close on the boot.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In FIG. 1 the subject semi step-in binding attachment for a hard shelled boot is designated by [0017] general reference number 10. The cam lever locking toe clip 11 is held in place at a preset position by the hold down plate 12. Bolt 13 and nut 14 attach plate 12 at the top and also provide tension. The expanded section 15 is the cam lever balance point and houses the front of the toe bale 19 as well as split tube 16. Bolt 17 and barrel 18 attach the bottom of plate 12 to clip 11 and provide the required tension. Toe bale spring 20 holds toe bale 19 in a fixed position. The open tab 32 on the binding cap 29 anchors toe bale spring 20 which is wrapped around the toe bail 20 at the center and at the bottom. Toe guide bar 21 is flared at the top and is attached to the toe binding cap 29 by bolt 20 and nut 23. Bolt 25 and nut 26 attach heel binding guide bars 24 which are flared at the top to heel binding cap 30. Spring 28 is wrapped around the center and bottom of bale 27 and anchored by tab 31 on binding cap 30. Spring 28 holds bale 27 in a preset forward biased position. A length of split tubing 16 is fitted over the center section of bale 19 and under the raised part 15 of hold down plate 12 to help provide the friction required to hold the toe cam lever locking clip 11 in an open or a closed position. The toe guide bars 21 are flared at the top and are attached to the toe binding cap 29 by bolts 21 and nuts 22. Toe guide bars 21 guides the boot 31 onto cap 29. Heel bale 27 is held in a forward position by heel bale spring 28. Boot 31 sits on binding toe cap 28 and binding heel cap 30.
While the invention has been particularly shown, described and illustrated in detail with reference to the preferred embodiments and modifications thereof, it should be understood by those skilled in the art that equivalent changes in form and detail may be made therein without departing from the true spirit and scope of the invention as claimed, except as precluded by the prior art. [0018]
