Title:
PROPULSION DEVICE UTILIZING ECCENTRIC ACTION
Document Type and Number:
Japanese Patent JP2018176835
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a propulsion device that is compact and lightweight, inexpensive, low in power consumption, and user-friendly.SOLUTION: A propulsion device 1 includes: a housing 2; a driving member 3 (rotary motor) that is provided in the housing 2 and causes a weight 4, which is separated in a radial direction from a center axis 3a, to make a circular motion with the center axis 3a as a center; and plural grounding members 5 (plural ciliary legs 5a and 5b) that ground the housing 2. The plural grounding members 5 each have a spring property for varying a distance between the housing 2 and a contact surface 9. An eccentric action exerted by causing the weight 4 to make a circular motion and the spring properties of the plural grounding members 5 are used to generate in each of the plural grounding members 5 a propulsive force that has a magnitude relationship to an advancing direction (forward, backward, rightward, or leftward).SELECTED DRAWING: Figure 1
