摘要： PROBLEM TO BE SOLVED: To reduce an air current noise generated at a through hole 23a part in which a pantograph frame 22a provided at a cover 20a is inserted.
SOLUTION: A pantograph device includes a second cover 29 having first, second and third cover elements 30-31, provided at an opening between a peripheral edge of the through hole 23a and an outer peripheral surface of the pantograph frame 22a opposed to this peripheral edge. The opening is always blocked irrespective of a displacement of the pantograph frame 22a by this second cover 29.

摘要： PROBLEM TO BE SOLVED: To suppress generation of air current noise when traveling at high speed.
SOLUTION: Insulators 17 and 17, an underframe supported by each insulator 17, 17, and a pantograph frame 21 supported to rise and fall freely on the underframe except the upper part thereof are covered with an intermediate cover 20 and a pair of end part covers 22 and 22. Upper part of the pantograph frame 21 is projected above the intermediate cover 20 through a through hole 26 formed therein and a collector shoe 7 is supported at the upper end part thereof. The above-mentioned problem can be solved by preventing wind from blowing against the parts covered with the covers 20 and 22.

摘要： PROBLEM TO BE SOLVED: To obtain a current collecting shoe device capable of detecting the phenomenon that a force acting on a friction part has become larger than a force in a normal state between the upper surface of each sliding plate 9 and the lower edge of an overhead cable.
SOLUTION: A shoe body 16a is supported to the upper end of a pantograph device 1 so as to be swingably displaced around an axis 19 arranged in the width direction of a railway vehicle. The shoe body 16a is energized by a centering spring toward a neutral position where the upper surface of the sliding plate 9 and the roof surface of the railway vehicle are parallel with each other. By detecting that the shoe body 16a has been displaced at an prescribed angle or larger with respect to the neutral position by using a pair of limit switches 18a, 18b, it can be recognized that the force has become larger than a force in a normal state.

摘要翻译：要解决的问题：为了获得能够检测作用在摩擦部分上的力已经变得比每个滑板9的上表面和下滑板9的上表面之间的正常状态的力大的现象的集电鞋装置架空电缆的边缘。解决方案：鞋体16a被支撑在放弓装置1的上端，以围绕布置在铁路车辆的宽度方向上的轴线19摆动地移位。鞋体16a通过定心弹簧朝向中空位置被激励，在该位置，滑板9的上表面和铁路车辆的车顶表面彼此平行。通过使用一对限位开关18a，18b，通过检测到鞋体16a相对于中立位置已经以规定角度或更大的位移，可以认识到力已经变得大于正常状态下的力。版权所有（C）2007，JPO＆INPIT
