发明名称 DEVICE ATTRACTED TO WALL SURFACE AND MOVABLE ALONG THEREON
摘要 PURPOSE:To make a device movable so smoothly while being attracted onto a wall surface, by making pressure, which renders a partition wall contact with a wall surface, reducible without varying the suction force acting on the wall surface. CONSTITUTION:A mobile device is provided with a pressure receiving body 2, while this pressure receiving body 2 is constituted so as to make it movable on a wall surface as being attracted to the wall surface by a suction device. A partition wall 8 is of almost U-shaped from in type, and its outer end is locked to a peripheral edge part of the pressure receiving body 2, and its inner side end is locked to an inner surface of the body 2 and that its projection part 18a is designed so as to be touched to the wall surface. The partition wall 18 forms a fluidic dense, first decompression region substantially in cooperation with the pressure receiving body 2 and the wall surface 4, while the projection part 18a of the partition wall 18 forms a second decompression region 22 in cooperation with the pressure receiving body 2. The decompression region 22 is connected to a vacuum pump via a differential pressure regulating valve 30 while the compression region 20 directly to the vacuum pump, both via pipes 40 and 24, respectively. Thus the mobile device is attractable to the wall surface.
