  • Patent number: 10718407
    Abstract: A chain bending limiting attachment includes first bending limiting members and second bending limiting members. The first and second bending limiting members are detachably attached to a chain to be arranged in a series arrangement direction. Each first bending limiting member includes a first engaging portion. When the chain bends in a first direction, the first engaging portion engages with another first bending limiting member adjacent to the first bending limiting member in the series arrangement direction to limit bending of the chain in the first direction. Each second bending limiting member includes a second engaging portion. When the chain bends in a second direction, the second engaging portion engages with another second bending limiting member adjacent to the second bending limiting member in the series direction to limit bending of the chain in the second direction.

  • Patent number: 10710837
    Abstract: The guide apparatus for a long object comprises: a movable portion that is capable of reciprocal movement in a reciprocal direction; a fixed portion; a pair of sheets that have flexibility; and a guide member. The fixed portion is fixed so that the movement in the reciprocal direction is not possible. The pair of sheets, with a curved part formed at an intermediate position in the longitudinal direction, couple the movable portion and the fixed portion. The guide member reciprocates in the reciprocal direction while guiding the movable portion and the pair of sheets so that the pair of sheets reciprocate in the reciprocal direction as the curved part is shifted in accordance with the reciprocal movement of the movable portion. The guide member forms, together with the pair of sheets, a storage chamber for storing a long object.

  • Publication number: 20200130942
    Abstract: An elongated object guiding device includes an elongated protection guide portion, inner wheels, outer wheels, a first rail surface, a second rail surface, at least one divided portion, and a restriction guide. The outer wheels are located at positions different from those of the inner wheels in the longitudinal direction of the protection guide portion and located farther from the protection guide portion in the width direction than the inner wheels. The divided portion is configured by dividing the first rail surface and the second rail surface. The divided portion allows the inner wheels and the outer wheels to move along a curved portion. The restriction guide limits a range in which at least the inner wheels or the outer wheels moves away from the first rail surface and the second rail surface.

  • Patent number: 10290394
    Abstract: A cable includes a flexible coated wire, a multi joint support member, and a flexible sheath member that covers the multi joint support member and the coated wire. The multi-joint support member is formed by pivotally coupling adjacent ones of a plurality of link members arranged in series. Turning of the multi joint support member in a first direction in a direction intersecting a serial direction is allowed until becoming equal to a predetermined radius of curvature and turning of the multi joint support member in a second direction, which is opposite to the first direction, is restricted.

  • Patent number: 10221919
    Abstract: A long object guide device includes an articulated support member, which includes link members arranged in series. Adjacent ones of the link members are rotationally coupled to each other. The articulated support member is permitted to turn to a predetermined bending radius in a first direction that intersects a series arrangement direction. The articulated support member is restricted from turning in a second direction that is opposite to the first direction. The long object guide device guides flexible covered wires while protecting the covered wires. The guide device includes an end. The guide device includes a fixation member that is fixable to a counterpart member while coupled to one of the link members that corresponds to the end of the guide device.

  • Publication number: 20180320757
    Abstract: An elongated object guiding device includes a protective guide and a guide rail. The protective guide includes a plurality of links. The links form an accommodation cavity that accommodates an elongated object. The protective guide guides while protecting the elongated object accommodated in the accommodation cavity. The guide rail moves back and forth while guiding the protective guide as the protective guide moves back and forth in a longitudinal direction. The protective guide includes a plurality of engagement portions. The guide rail includes a guide groove that engages the engagement portions and extends in the longitudinal direction to allow the protective guide to be guided. The guide groove restricts movement of the engagement portions in a direction intersecting the longitudinal direction and allows movement of the engagement portions in the longitudinal direction.

  • Patent number: 10083777
    Abstract: A flat cable assembly has a belt-like portion. In the belt-like portion, cables capable of transmitting power and/or signals and a pair of tubular portions positioned at the opposite ends in the width direction are arranged in parallel with one another. Each tubular portion has a longitudinal multi joint supporting member inserted therein in a state where link members are arranged in series, and adjacent link members are pivotally connected to one another. The multi-joint supporting members are configured to limit pivoting motion in a first direction that intersects the longitudinal direction in a range to a previously defined bend radius, and to restrict flexing in a second direction that is opposite from the first direction.

  • Patent number: 9809244
    Abstract: A housing structure includes first and second housings and first and second rotation transmitting members. The first and second housings house a shaft. The first rotation transmitting member is provided coaxially with the shaft. The second rotation transmitting member is arranged so as to transmit power to the first rotation transmitting member. The first and second housings are combined with each other so that mating surfaces of the first and second housings that are unparallel to an axis of the shaft are contacted. The first housing includes a first guide portion that protrudes from the mating surface of the first housing. The second housing includes a second guide portion that engages with the first guide portion. The first and second guide portions are engaged with each other along a circumferential direction of the axis and guide relative rotation of the first housing and the second housing around the axis.
