A circuit arrangement embodied within the construction of a ski. A conductor plate is provided inside the ski and has at least one threaded opening therein for threadedly receiving a screw which facilitates a fastening of a base plate for a ski binding member to the upper surface of the ski. The screw is threadedly received in the opening and the base plate of the ski binding member is clamped between the head of the screw and the upper surface of the ski. The screw is electrically insulated from the base plate of the ski binding member but does provide a metal-to-metal contact with the conductor plate. The base plate of the ski binding member and the conductor plate are electrically conductive so that these two plates can function as components of an electrical circuit embodied within the ski. A battery can be mounted within the ski and the aforementioned base plate and conductor plate utilized in circuit with the battery to provide power to electrical loads located elsewhere on the ski, as for example in the ski binding members.
In a ski construction having an electrically conductive base plate, an electrically operable load on a ski binding which is mounted on said base plate, a battery operatively connected to said load to provide the electrical power necessary to effect an operation of said load, the improvement comprising an electrically conductive anchor plate means embedded in said ski and being vertically spaced from and insulated from said base plate, an electrically conductive fastening means for fastening said ski binding to at least one of said base plate and said anchor plate means, said battery having a positive terminal electrically connected to one of said base plate and said anchor plate means and a negative terminal electrically connected to the other of said base plate and said anchor plate means, said load having at least first and second electrical conductors thereon, said first electrical conductor being electrically coupled to said fastening means, said second electrical conductor being electrically coupled to said other of said base plate and said anchor plate means.
