    • PROBLEM TO BE SOLVED: To improve durability of elastic pads, while making a spring constant of the elastic pads uniform.
      SOLUTION: The elastic pads 10 and 11 of a set of upper-lower two sheets, are installed between an under surface of a sleeper 3 and an upper surface of ballast 2. A truncated cone-shaped projection projecting toward the other surface, is arranged on and meshed with opposed base surfaces of the respective pads 10 and 11 by interposing clearance. Respective projection upper surfaces are allowed to abut on a base surface of the respectively opposed other pads 11 and 10. One projection of one pad is surrounded in an equal azimuth by the projection of the opposed other pads. The respective projections are restricted by the other projection after being deformed by a certain degree in the horizontal direction toward the clearance. Thus, since the projections are distributed over the whole pad, deformation performance is uniformized over the whole surface, and a spring constant and a settlement quantity are regulated by restriction of its deformation, and shearing force can be reduced by checking excessive deformation. When the projection is formed in a hollow shape, the deformation performance is further improved.

    • 要解决的问题:为了提高弹性垫的耐久性,同时使弹性垫的弹簧常数均匀。 解决方案:一组上下两张纸的弹性垫10和11安装在卧铺3的下表面和压载物2的上表面之间。朝向另一表面突出的截头圆锥形突起 通过插入间隙而布置在相应的垫10和11的相对的底表面上并与之啮合。 允许各个投影上表面邻接在相对的另一个焊盘11和10的基面上。一个焊盘的一个突出部通过相对的另一个焊盘的投影以等方位包围。 在水平方向上朝向间隙变形一定程度之后,各个突起被另一个突起限制。 因此,由于突起分布在整个焊盘上,变形性能在整个表面上均匀化,并且通过限制其变形来调节弹簧常数和沉降量,并且可以通过检查过大的变形来减小剪切力。 当突起形成中空形状时,变形性能进一步提高。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To improve workability of mounting work while confirming a spring clip visually from the outside.
      SOLUTION: A base plate 5 of high bed type having a cavity part 4 at an inner end is formed by forming a slide plate 1 and a body part 2 together with an outward wall 3a integrally. Downward protruding parts 11, 11 are provided on both sides of a rear surface of the slide plate 1. Locking grooves 30, 30 having an opened side each are formed on both sides of the outward wall 3a. A pair of bar springs 6, 6 are inserted into the inside through sides of the base plate 5 and each of inner ends 60 protrudes from the cavity part 4. A halfway section of each bar spring 6 is pressed by the downward protruding part 11, and each of outer ends 61 is locked in the locking groove 30 to energize each of inner ends 60 of each bar spring 6 in the downward direction always and tighten a leg part 70 of a rail 7 elastically.

    • PROBLEM TO BE SOLVED: To provide a switch guard which is easy to work, excellent in durability, and facilitates adjustment of a flangeway width, and to provide a mounting member therefor and a switch guard mounting structure.
      SOLUTION: A mounting portion 12b of the switch guard 12 has a flat surface 12i which is to be mounted on the mounting member 13, and a mounting portion 13a of the mounting member 13 has a convex surface 13d for mounting the flat surface 12i thereon. Therefore unlike a conventional switch guard, bending work is dispensed with, and the mounting position of the switch guard 12 can be easily changed. Further an adjusting washer 17 having a fastening bolt 15 attached thereto, can be inserted and mounted on the fastening bolt 15, and therefore the flangeway width W can be easily adjusted to a specified value. Furthermore, spherical surface portions 13c, 18a make contact with each other, and therefore even if the position of the switch guard 12 is changed, an eccentric load applied to the fastening bolt 15 can be reduced.

    • PROBLEM TO BE SOLVED: To solve the following problem of a conventional joint that: if derailment occurs, wheels and their flanges directly strike joint plates by large forces, bolt heads, and nuts by large power, and therefore not only the joint plates are damaged but also the bolts and nuts are cut, resulting in the disengagement of the bolts and disconnection of the rails from a joint portion, whereby the rails are lifted up to collide with a vehicle body.
      SOLUTION: There is provided an adhesive insulated joint according to which the joint plates 3 are fitted into both surfaces 12, 12 of a web of the rail via insulated adhesives 4, respectively, and fastened to the rail 1 with a bolt 6. The externally facing surface 31 of each joint plate 3 is formed in the vicinity of a virtual line L2 hung from the edge of the maximum width L1 of a rail head 11. Then bolt penetration holes 30, 30 and 10 are formed in both the joint plates 3 and the rail 1, and a recess 32 is formed in one of the joint plates 3 while a female screw 33 is screwed in the bolt penetration hole 30 in the other joint plate 3. Further the bolt 6 is inserted into the bolt penetration holes 30, 30 and 10, and the shaft edge 60 of the bolt 6 is tightly fastened to the female screw 33. Furthermore a shaft tip is finished so as to stay in the joint plate 3, and the bolt head 61 is sunk in the recess 32.
