Abstract:
An apparatus for traveling on a closed track on the surface of a wall comprising a moving platform movable along a guide rail disposed on the surface of a wall of a building, the moving platform including a supporting unit to slidingly and movably mate with the guide rail; a rotational member to be connected to and driven to rotate by a driving means, the rotational member being disposed on the moving platform; and a plurality of mating units disposed around the rotational member at the same distance from each other, mating with guide faces of driving guides disposed on the surface of a wall, and for generating a driving force, in which the guide faces of the driving guides disposed on the surface of a wall are formed in a substantially cycloidal shape so that a substantially constant speed in a direction of the movement along the surface of a wall is imparted to a rotational center of the rotational member,wherein the guide rail disposed along the surface of a wall of a building includes a plurality of rails which form a closed track, the supporting units for mating with the rails are disposed at a plurality of positions of the moving platform separated from each other,the plurality of rails differ in phase from each other so as to support the moving platform, of which supporting units mate with the rails, substantially in the same orientation while the moving platform is traveling, and are disposed separated from each other so as not to contact and intersect each other, andthe guide faces of the driving guides project from the rails toward the moving platform.
