Title:
APPARATUS CAPABLE OF BEING SUCKED TO SURFACE AND MOVING ALONG THE SAME
Document Type and Number:
WIPO Patent Application WO/1994/025328
Kind Code:
A1
Abstract:
An apparatus capable of being sucked to a surface and moving along the same comprises a pressure receiving body, a partition device mounted on the pressure receiving body for cooperating with the pressure receiving body and the surface to define a pressure reducing space, and a pressure reducing device for discharging a fluid from the pressure reducing space to reduce a pressure in the pressure reducing space. The partition device includes a lip portion extending along the surface. Provided on a portion, except for an outer peripheral portion on an opposed surface of the lip portion, of the partition device positioned to be opposed to the surface are a plurality of abutting means which are spaced from one another. The outer peripheral portion on the opposed surface of the lip portion is brought into contact with the surface, and the abutting means on the portion except for the outer peripheral portion on the opposed surface of the lip portion are brought into contact with the surface, so that a gap communicating to the pressure reducing space is left between the portion, except for the outer peripheral portion on the opposed surface of the lip portion, and the surface.
