Title:
LINEAR-MOVING EXPANSION DEVICE AND LINEAR-MOVING EXPANSION TYPE GATE DEVICE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2015213974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a linear-moving expansion device and the like which achieves reduction in size and weight, and which achieves reduction in cost with a simple structure.SOLUTION: A linear-moving expansion device 1 includes: a long movement piece group 3 comprised by connecting a plurality of movement pieces 20 in a left and right direction via a rotary shaft 23; and a housing 2 for accommodating the movement piece group 3 inside. The movement piece 20 rotates around the rotary shaft 23 between: a contact position P1 in which rotation downward is restricted by coming into contact with an end part of the adjacent other movement piece 20 and movement along an axial direction of the rotary shaft 23 is also restricted; and a separation position P2 in which movement along the axial direction is allowed by rotating upward so as to separate from the end part of the other movement piece 20. The movement piece 20 which rotates to the contact position P1 configures an arm part 3B which moves in a linear manner arrayed in one row with other movement pieces 20. The movement piece 20 which rotates to the separation position P2 configures a spiral part 3A for moving in a spiral manner by displacing to one axial direction inside the housing 2.
