  • Patent number: 11873859
    Abstract: A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.

  • Patent number: 11199207
    Abstract: The motion guide device clamper mechanism includes a clamper main body connected to the movable member, an inner face having a tapered shape so that the distance between the facing faces is narrower toward the end of one face of the track member, and one rolling member disposed between the facing faces of the one face of the track member and the inner face. The rolling member receives a pressing force toward a position where the distance between the facing faces of one face of the track member and the inner face of the clamper main body is narrow, so that a frictional force based on the taper shape acts on the rolling member, and the restraint of the clamper main body with respect to the track member is performed. Further, a frictional force based upon the taper shape is released and the non-restraint of the clamper is performed.

  • Patent number: 10690183
    Abstract: In this motion guide device (10), a track member (20) has a recess or protrusion (51) that is formed in a longitudinal direction, and a moving member (30) has a holding protrusion or holding recess (53) that corresponds to the recess or protrusion (51) formed in the track member (20). When force is applied in a direction that would cause relative separation of the moving member (30) and the track member (20), the holding protrusion or holding recess (53) holds onto the recess or protrusion (51) such that the moving member (30) and the track member (20) are unable to be separated. With this configuration, a motion guide device that is both compact and capable of withstanding a strong external load can be obtained.
