Abstract
A clutch mechanism for a hand tool comprises a body with a converging internal wall surface which is mounted on a rod. The body houses a set of ball bearings which are biased along the converging wall into an engaged position with a rod passing through the body. An axial force applied to one end of the body causes the balls to grip the rod. Whereas a force applied to the other end of the body releases the balls from the rod.
Claims25
A clutch mechanism for a rod comprising a body having an aperture, through which the rod extends, the aperture being partially defined between first and second ends of the body by a wall surface converging toward the rod at the first end, the mechanism further comprising a rod engaging member moveable along a respective wall surface between a first position, in which the engaging member is engaged between the wall surface and the rod such that the body is movably engaged with the rod when a force is applied to the first end of the body, and a disengaged position, in which the rod is moveable relative to the body, the converging wall surface defining a guide having a lateral profile which is complimentary to an adjacent surface of the engaging member.
A clutch mechanism for a rod comprising a body having an aperture, through which the rod extends, the aperture being partially defined between first and second ends of the body by a wall surface converging toward the rod at the first end, the mechanism further comprising a rod engaging member moveable along a respective wall surface between a first position, in which the engaging member is engaged between the wall surface and the rod such that the body is movably engaged with the rod when a force is applied to the first end of the body, and a disengaged position, in which the rod is moveable relative to the body, the engaging member being a roller bearing adapted for rolling contact with the rod.
A clutch mechanism for a rod comprising a body having an aperture, through which the rod extends, the aperture being partially defined between first and second ends of the body by a wall surface converging toward the rod at the first end, the mechanism further comprising a rod engaging member moveable along a respective wall surface between a first position, in which the engaging member is engaged between the wall surface and the rod such that the body is movably engaged with the rod when a force is applied to the first end of the body, and a disengaged position, in which the rod is moveable relative to the body, the engaging member being wedge-shaped and adapted for sliding contact with the rod.
A clutch mechanism for a rod comprising a body having an aperture, through which the rod extends, the aperture being partially defined between first and second ends of the body by a wall surface converging toward the rod at the first end, the mechanism further comprising a rod engaging member moveable along a respective wall surface between a first position, in which the engaging member is engaged between the wall surface and the rod such that the body is movably engaged with the rod when a force is applied to the first end of the body, and a disengaged position, in which the rod is moveable relative to the body, the rod formed with axially extending surfaces having a lateral profile which is complimentary to an adjacent surface of the engaging member.
