Title:
WALL WALKING MACHINE
Document Type and Number:
Japanese Patent JPS61222878
Kind Code:
A
Abstract:
PURPOSE:To make a wall walking machine in a simple mechanism and in light weight by coupling together a pair of legs, on the right and left, equipped each with a suction cup through a motion inverting mechanism so that either of the legs travels in the direction of walking while the other is fixed attracted to the wall surface. CONSTITUTION:Support frames 4 for a pair of legs 1a, 1b on the right and left are coupled with their mating mounting frames 5 for suction cup 8 by the use of expansion/contraction mechanisms 6. A liquid pressure actuator 7 to narrow together and move apart each set of such a supporting frame 4 and mounting frame 5 is provided in the middle. The supporting frames 4 are supported slidably through an arm 14 installed at a cylinder 10 of drive mechanism 2. A gear 17 of a motion inverting mechanism 3 is installed on the undersurface of this cylinder 10. The gear 17 is meshed with a rack 18 furnished on the inside of each supporting frame 4. The left and right supporting frames 4 are thus advanced alternately by this motion inverting mechanism 3 to accomplish walking on the wall.
