SLOPE DEVICE FOR ELIMINATING LEVEL DIFFERENCE
To provide a constitution capable of constituting an expansion/contraction stroke between the lowest position and the highest position of a movable plate long and excellent in quick expansion/contraction operation and operability for expansion/contraction, concerning an expansion/contraction mechanism for vertically moving the movable plate in a slope device for eliminating level difference.SOLUTION: An expansion/contraction mechanism (14) is composed of: an upper pivot member (21) pivotally connected to a movable plate; a lower pivot member (23) pivotally connected to a fixed body or a leg seat; and a rotary drive member (24) whose upper and lower ends are mutually screwed to the lower and upper pivot members by first screw means (26) and second screw means (27), which are mutually reverse threaded. The rotary drive member (24) is screwed into the cylindrical part (21a) of the upper pivot member and is configured such that an upper-end part of the rotary drive member, which is inserted upward from the cylindrical part (21a), is received in a housing space (25).SELECTED DRAWING: Figure 5
【課題】段差解消用スロープ装置における可動板を上下動させる伸縮自在な伸縮機構に関して、可動板の最下位と最上位の位置の間における伸縮ストロークを長く構成することができ、しかも、迅速な伸縮動作と、伸縮のための操作性に優れた構成を提供する。【解決手段】伸縮機構(14)は、可動板に枢結された上側枢支部材(21)と、固定体又は脚座に枢結された下側枢支部材(23)と、上下両端部をそれぞれ下側枢支部材と上側枢支部材に対して相互に逆ネジとされた第１ネジ手段(26)と第２ネジ手段(27)により螺合された回転駆動部材(24)により構成されており、回転駆動部材(24)は、上側枢支部材の筒部(21a)に螺挿され、筒部(21a)から上方に挿出された上端部を収容空間(25)に受け入れられるように構成されている。【選択図】図５
