Claims

[Claims for Utility Model Registration] (1) In a pantograph formed by arranging small pieces of slide plates divided into a large number of pieces in the longitudinal direction of the boat body on the upper surface of the boat body, the small pieces of slide plates divided into a large number of pieces are collectively durable. Fixed to a flexible sheet with arc properties,
One or more elastic bag-like bodies filled with a gas such as air are arranged between the flexible sheet and the frame of the boat body over the rows of the slider strips divided into a large number of pieces. , the end of the flexible sheet in the direction perpendicular to the longitudinal direction of the boat body covers the side surface of the boat body, and the flexible sheet is fastened to the frame with a fastening material. A pantograph collector boat featuring (2) Arrange slide plates divided into a plurality of pieces in the longitudinal direction of the boat on the upper surface of the boat, and each of the slide plates divided into a plurality of pieces has a U-shaped cross section and is approximately the same as the slide plate. It is attached to a support plate of the same length, and between this slide plate and the support plate, it has conductivity and elasticity, and is fixed to the hull frame located along the entire length of the plurality of slide plate rows and on the outside of both ends thereof. Holding a bottom plate made of thin metal plate that communicates with the fixed slide plate part,
Both side surfaces of the support plate are arranged on both sides of a boat frame having an upwardly facing U-shaped cross section via a sliding material, and the space between the support plate and the boat frame contains air bubbles and has elasticity. A collector boat for a pantograph characterized in that a sponge rubber is arranged to elastically support a slider plate. (3) The shape of the sponge rubber may be such that it has a plurality of holes passing through it in the transverse direction of the boat hull, or it is shaped so that there is space inside, and it is shaped like a sandwich rubber in multiple stages in the transverse direction of the boat hull. 2. A current collecting boat for a pantograph according to claim 2, characterized in that the current collecting boat of a pantograph is made of an elastic bag-like body which is sandwiched together or is filled with gas instead of sponge rubber. (4) A bag-like body filled with sponge rubber or gas having a larger elastic modulus than the intermediate portion is disposed at the connecting portion with the fixed slider provided at both longitudinal ends of the slider row. Claim No.
The pantograph collector boat described in (2).
