  • Patent number: 10960945
    Abstract: A wall surface suction-type travel device includes a main body, a cushion, a plurality of support wheels, a crawler, and a drive source. The main body includes a wall-surface facing section and a draw-in port. The cushion is disposed on the wall-surface facing section of the main body and surrounding an edge of the draw-in port. The cushion is elastically deformable and has a slide surface sliding on the wall surface when the wall surface suction-type travel device travels on the wall surface. The plurality of support wheels are disposed on the main body. The crawler is an endless belt suspended on the plurality of the support wheels. The crawler has a grip surface put into contact with the wall surface when the wall surface suction-type travel device travels on the wall surface. The drive source is to rotate the crawler.

  • Patent number: 10836446
    Abstract: A wall surface suction travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular to both a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.

  • Patent number: 10696338
    Abstract: A wall surface suction-type travel device is configured to travel on a wall surface while being suctioned on the wall surface. An intermediate chamber communicates with decompression chambers facing the wall surface. A suction device sucks in air from the intermediate chamber to decompress the intermediate chamber. Principal communicating parts allow the decompression chambers to communicate with the intermediate chamber. Secondary communicating parts allow the respective decompression chambers to communicate with the intermediate chamber. Valves face openings of the respective principal communicating parts. An area of an opening of each of the secondary communicating parts is smaller than an area of the opening of a corresponding one of the principal communicating parts.

  • Patent number: 10483743
    Abstract: A cable holding device for holding a cable, includes a first member, a second member and a fixing member. The first member has a first through hole through which the cable is to pass. The second member has a second through hole through which the cable is to pass. The fixing member fixes the second member to the first member in such a condition that the second through hole partially overlaps the first through hole to hold the cable by an inner periphery of the first through hole and an inner periphery of the second through hole.
