Document Type and Number:
Japanese Patent JP2015075231
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a mechanism for displaceably supporting articles of various weights on desired positions with a small and light-weight structure.SOLUTION: An article supporting device 1 includes a base member 2, a supporting member 3, a spring member 4, a spring force transmitting member 5, a linear operation mechanism composed of a spring seat plate 6 and an adjustment screw shaft 10, and a cam follower member 7. The cam follower member is pressed to a downward cam face 15 of the supporting member, an upward cam face 18 of the spring force transmitting member, and a lateral cam face 22 of the base member by a load of an article and a spring force of the spring member. A height position of the spring member is adjustable by the spring seat plate 6 in the base member at one end 4a, and the other end 4b biases the spring force transmitting member vertically upward. A pressing force to the cam follower member, of the lateral cam face includes a vertical component according to a height position of the supporting member. Each of the cam faces is designed so that the load, the spring force and the pressing forces to the cam follower member from the cam faces, acting around the cam follower member are balanced.
