ABSTRACT:
An improved swiveling wheel assembly comprising a brake member including a toggle lever mechanism comprising a first and a second element rotatably connected together. The first element is rotatably fastened to the upper end of a rod-shaped locking member and the second element is rotatably connected to a vertical fastening member. A coupling means is also included and used for coupling one of the first and second elements to a cam member whereby, when the cam member rotates from a first or second position into a third position, the toggle lever mechanism is brought from an unextended position into essentially an extended position, wherein a line drawn between the axes of rotation of the toggle lever mechanism is essentially aligned with the longitudinal axis of the locking member and the locking member is displaced downward against a spring member with respect to the first and second positions whereby a lower edge of a locking disk is pressed against the wheel.
