<p>CANADIAN PATENT APPLICATION OF CHRISTER VAHLBERG and ODD HIELM FOR ANTI-THEFT DEVICE FOR OUTBOARD MOTORS An anti-theft device for clamping and locking an outboard motor to a transom board comprises a bracket which is connected with an upper part of the outboard motor and forms together with this part a substantially U-shaped suspension rack for mounting the outboard motor on the outboard side of the transom, and with a free leg of the bracket extending down on the inboard side of the transom, and a clamping fixture including a clamping screw for urging said free leg of the bracket away from the inboard side of the transom while clamping 1a the motor to the outboard side thereof. Tile clamping fixture is in the form of a screw jack which comprises, in addition to said clamping screw, a hollow body forming a protective housing for receiving and shielding the screw shank and, connected to one end of the housing, an open ended protective casing for receiving and shielding the screw head as well as a key-operated lock mounted therein for cooperation with the screw head for locking the screw against rotation; the protective housing comprises in an upper wall thereof an opening for receiving an end portion of said leg, and the screw shank extends from the casing into the housing through an opening formed in a partition between the housing and the casing; the end of said hollow body opposite to the casing forms a base adapted to hear against the inboard transom side, the screw head is adapted to bear against said partition and the screw shank extends through and engages a threaded bore in said end portion of the shank, whereby the screw, when being rotated, urges said bracket leg and thereby the outboard motor forward and said base end of the hollow body backwards against the inboard side of the transom thereby clamping the motor firmly to the transom, and when the screw then is locked, the screw is non-rotatable, shielded and substantially inaccessible and thus safely protected. lb</p> |
