Claims

[Scope of Claim for Utility Model Registration] (1) A leaf spring for elastic fastening of a rail used in a sleeper with a structure in which a spring plug is integrally embedded in a concrete sleeper support. It is a horizontal spring type in which the entire surface of the bottom spring in the plate width direction is in direct contact with the upper surface and side surface of the bottom of the rail, and when the upper spring is tightened, the tips of the lower spring and the top spring are in contact with the rail. A leaf spring for concrete sleepers characterized by having a double spring type that acts as a spring on the top surface of the bottom. (2) In the leaf spring for concrete sleepers according to claim 1, when the leaf spring is fastened to the rail, the tip of the upper spring contacts both the tip of the lower spring and the upper surface of the bottom of the rail, or the lower spring 1. A leaf spring for concrete sleepers, characterized in that the leaf spring for concrete sleepers is shaped so that the end part of the lower spring and the end part of the upper spring act as springs on the upper surface of the bottom of the rail. (3) In the leaf spring for concrete sleepers according to claim 1 or 2, with respect to the required dimension from the bottom side of the rail to the spring holder, the dimension of the corresponding part of the lower spring has a gauge. A leaf spring for concrete sleepers characterized by using leaf springs of two sizes, large and small, adjusted to account for the amount of change.
