Abstract:
1. A pair of splitboard boot bindings, each boot binding for securing a rider's boot to a splitboard, the splitboard having a pair of conjoinable ski members, the ski members when conjoined together defining a snowboard riding configuration and when used separately defining a ski touring configuration, each boot binding for engaging a snowboard mounting block assembly affixed crosswise to the top face of the splitboard in snowboard riding configuration and for engaging a ski mounting assembly affixed to one of the ski members in ski touring configuration, each boot binding of said pair comprising, a box girder having a top plate member with a top surface, a bottom plate member with a bottom surface, a medial web member, a lateral web member, a heel end and a toe end; wherein, a) said top surface is proportioned for contactingly receiving an applied torque from the sole of the rider's boot, said box girder having means for detachably securing the rider's boot to said top surface; b) said bottom plate member comprises parallel inside flange edges forming an underside channel for receiving and grippingly conjoining said box girder to the snowboard mounting block assembly affixed to a top face of the splitboard, and is proportioned with widened bottom outside mediolateral flange edges for dynamically transmitting torque from the sole of the rider's boot to the top face of the splitboard; c) said medial and lateral web members underlie said top plate and join said top plate to said bottom plate, forming a rigid mechanical linkage therebetween; d) said medial and lateral web members each comprise a transverse coaxial hole on a pivot axis proximate to said toe end, said transverse coaxial hole for receiving an insertable toe pivot pin; and, e) said medial and lateral web members have each a lateral face and a medial face dimensionally separated by a lateral-to-medial width, said lateral-to-medial width having a maximum proximate to said transverse coaxial pivot hole and tapered to a minimum posteriorly therefrom.
