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 a part of the center of the plate width is perforated at the tip of the lower spring that is in direct contact with the upper surface and side surface of the bottom of the rail, and the upper spring that is continuous with the lower spring. A leaf spring for a PC sleeper, characterized in that the upper spring and the lower spring act on the upper surface of the bottom of the rail when the upper spring is tightened. (2) In the leaf spring for PC sleepers according to claim 1, the lower spring is supported on the upper surface of the bottom of the rail and the spring holder, and when the upper spring is tightened, the tip of the upper spring is the tip of the lower spring. and the upper surface of the bottom of the rail, or securely contact the tip of the lower spring, so that the tip of the lower spring and the tip of the upper spring are
A leaf spring for PC sleepers characterized by a spring acting on the upper surface of the bottom of the rail. (3) In the leaf spring for PC sleepers according to claim 1, the upper spring is supported on the upper surface of the bottom of the rail and the spring holder, and when the upper spring is tightened, the upper spring presses the rail and A leaf spring for a PC sleeper, characterized in that the lower surface is in reliable contact with the tip of the lower spring, and the upper and lower spring tips act as springs on the upper surface of the rail bottom. (4) In the leaf spring for PC sleepers as set forth in claim 1, 2, or 3, the corresponding part of the lower spring is A leaf spring for PC sleepers characterized by using leaf springs of two sizes, large and small, whose dimensions are adjusted to account for the amount of gauge change.
