DESCRIPTION
(22) A splitboard is a snowboard that splits into at least two skis for climbing uphill in a touring configuration. When the splitboard is in the touring configuration, traction skins can be applied to the base of the snowboard to provide traction when climbing uphill. The user can use the skis like cross country skis to climb. When the user reaches a location where the user would like to snowboard down a hill, the user removes the traction skins and joins the at least two skis with a joining device to create a snowboard. An integral part of achieving optimal performance, such that the splitboard performs like a solid snowboard, is the joining device's ability to prevent the at least two skis from moving relative to each other.
(23) Where the skis touch to create a snowboard is referred to as the seam. If a splitboard has relative movement between the at least two skis, torsional stiffness is lost, flex in the splitboard is compromised, and ultimately performance is reduced which leads to lack of control for the user. For a splitboard to perform like a solid snowboard the joining device should allow the at least two skis to act as one snowboard with, for example, torsional stiffness and tip-to-tail flex. The joining device also should prevent the splitboard skis from shearing or moving up and down relative to each other, moving apart in a direction perpendicular to the seam, sliding relative to each other in a direction parallel to the seam, and rotating about the seam. Existing devices do not provide sufficient constraint in all four directions, or do not provide constraint in all four directions.
(24) In order to fully constrain movement in the skis relative to each other in directions perpendicular and parallel to the seam, the joining device should create tension in itself and thus compression at the seam of the splitboard between the at least two skis. For this tension and compression to be obtained and still be able to easily separate the at least two skis, the joining device should have the ability to increase and decrease tension easily.
(25) Some existing devices lack, among other things, the ability to fully constrain rotation about the seam of the splitboard. Fully constraining rotation about the seam of the splitboard is an important element to making a splitboard ride like a normal snowboard. If the splitboard can rotate about the seam, the rider's input into the splitboard is delayed creating a less responsive ride down the mountain. Some devices rely heavily on the precision of installation to attempt to limit rotation about the seam of the splitboard. As a result, if the device is installed loosely, or when the device wears down with use, rotation about the seam of the splitboard can occur, the skis can move perpendicularly to the seam of the splitboard, and the skis can move parallel to the seam of the splitboard, thereby creating a less responsive ride down the mountain. Such devices also lack the ability to create tension in the joining device and compression in the seam of the splitboard.
(26) There is a need for a splitboard joining device that can quickly and easily join the skis of a splitboard to create a snowboard while preventing the splitboard skis from shearing or moving up and down relative to each other, moving apart in a direction perpendicular to the seam, sliding relative to each other in a direction parallel to the seam, and rotating about the seam.

(30) First attachment 302 can further comprise translational base portion 305, fixed base portion 304, lever 303, and links 314. Translational base portion 305 can further comprise shear tab 306, shear tab hook 319, slot 309, tip 308, friction teeth 307, drive flange 331, and link pivot 310. Fixed base portion 304 can further comprise lever pivot 313, mounting holes 311 and 312, slot stand-off 317, and retaining surface 318. Links 314 can have pivots 316 and 315. Lever 303 can have pivots 322 and 323 which can rotate on rivet 321, link pivots 320 and end 324. Slot stand-off 317 extends through slot 309. The thickness of slot stand-off 317 can be equal or slightly thicker than the thickness of translational base portion 305 to allow fixed base portion 304 to be tightened down to the top surface 104 of first ski 101 with fastener 336 through mounting holes 311 and 312. Fastener 336 can be a screw, bolt, rivet, or other suitable fastening device. Fastener 336 can also have nut 335 to attach fixed base portion 304 and first ski 101.
(31) In some embodiments, retaining surface 318 of fixed base portion 304 extends over the top of translational base portion 305 vertically constraining translational base portion 305. The closer the thickness of slot stand-off 317 to the thickness of translational base portion 305 the tighter the vertical constraint on translational base portion 305. Retaining surface 318 of fixed base portion 304 can constrain translational base portion 305 in a direction perpendicular to retaining surface 318, rotationally about the seam 103, and rotationally perpendicular to the seam 103.
(32) The width W1 of slot stand-off 317 can be equal to or slightly narrower than width W2 of slot 309. The interaction between width W1 of slot stand-off 317 and width W2 of slot 309 can constrain translational base portion 305 in a direction generally parallel to the seam 103 of the splitboard, the closer the width W1 to width W2 the tighter the constraint. The interaction between width W1 of slot stand-off 317 and width W2 of slot 309 can also constrain translational base portion 305 rotationally generally in the plane of retaining surface 318, the closer the width W1 to width W2 the tighter the constraint. In some embodiments, length L1 of slot stand-off 317 is less than length L2 of slot 309 to allow translational base portion 305 to move in a direction generally perpendicular to seam 103 as shown by dashed line A in
(33) Lever 303 can be attached though pivot holes 322 and 323 to fixed base portion 304 with fastener 321 through pivot hole 313. Fastener 321 can be a rivet, screw, bolt pin or other suitable fastener allowing rotation. Links 314 can attach to lever 303 through pivots 320 with a rivet, screw, pin or other suitable fastener. Links 314 can attach to link pivot 310 on drive flange 331 of translational base portion 305 with a rivet, screw, pin or similar fastener through pivot hole 315.
(34) As show in
(35) Second attachment 301 can attach to second ski 102 with fasteners 333 and 334. Fasteners 333 and 334 can be screws, rivets, or other suitable fastening mechanisms. Nuts 331 and 332 can further be used to attach second attachment 301 to second ski 102. Upon mounting, second attachment 301 can be adjusted with mounting slots 328 relative to second ski 102. To increase tension in the first configuration, end 335 can be moved away from seam 103. To decrease tension in the first configuration, end 335 can be moved towards seam 103.
