Abstract: A fifth wheel coupling device is adapted for a towing vehicle that vertically receives a kingpin of a trailer. The device includes a plate having a kingpin hole formed therethrough defining a vertical path adapted to permit entry of the kingpin into the kingpin hole and through the plate along the vertical path, and to prevent release of the kingpin out of the kingpin hole along a lateral path leading outside the plate. A support base is attached to the plate, and is adapted to mount the plate to the towing vehicle. A lifting mechanism is operatively connected to the plate and is adapted to be mounted on the towing vehicle for raising and lowering the plate relative to the trailer. A locking mechanism is movably attached to the plate and is provided with an actuating portion.

Abstract: A secondary lock assembly for a fifth wheel, where the fifth wheel includes a hitch plate with a rearward opening slot to receive a trailer kingpin and a transversely sliding primary locking member for retaining the kingpin within the slot. The assembly comprises a tie bar pivotally connected at its middle to the primary locking member and a transversely oriented pull bar pivotally connected at an inner end to the forward end of the tie bar. The pull bar comprises a rearward offset tab. A latch is pivotally connected roughly at the center of the latch to the forward end of the tie bar, and also pivotally connected at a point rearwardly and inwardly offset from the first pivoting connection to the offset tab. A detent extends from a transverse wall comprised in said hitch plate such that said detent lies in the same horizontal plane as said latch.

Abstract: A tibial insert includes a platform defining an upper bearing surface and a bottom surface. A keel of the tibial insert is coupled to the bottom surface of the platform and a rod of the tibial insert extends through a portion of the keel. A surgical method for knee arthroplasty is also disclosed.

Abstract: A tibial insert includes a platform defining an upper bearing surface and first and second keels extending downwardly from the platform. Each of the first and second keels includes an angled anterior face. A surgical method for knee arthroplasty is also disclosed.

Abstract: A fifth wheel assembly comprises a fifth wheel having a plurality of journal bearings extending generally downward from its underside, and an “I-shaped” transverse beam member for mounting the assembly to a truck frame. The beam member is dimensioned to span across parallel longitudinal truck frame members and it includes mounting flanges extending generally downward from either lateral side where the mounting flanges have a plurality of apertures for receiving suitable fasteners inserted therein for mounting said beam member to the truck frame members. The transverse member also includes a plurality of pivot bearing pairs to receive the journal bearings of the fifth wheel which is coupled thereto by a trunnion.
