Abstract

A bracket apparatus for a composite spring, may include a lower bracket disposed to come into contact with a composite spring when a U-bolt is fastened to a nut; an upper bracket disposed above the lower bracket so as not to be decoupled therefrom by the nut; and an elastic member disposed between the lower bracket and the upper bracket to provide a force such that the lower and upper brackets move away from each other.

First claim

What is claimed is:

1. A bracket apparatus for a composite spring, the bracket apparatus comprising:
a lower bracket disposed to contact with the composite spring when a U-bolt is fastened to a nut;
an upper bracket disposed above the lower bracket so as not to be decoupled therefrom by the nut; and
an elastic member disposed between the lower bracket and the upper bracket to provide a force such that the lower and upper brackets move away from each other,
wherein, when the composite spring is contracted according to a changed in atmospheric temperature so that a thickness of the composite spring is decreased and a gap is formed between the composite spring and the lower bracket due to a decrease in the thickness of the composite spring, the lower bracket moves toward the composite spring by restoring force of the elastic member to be maintained when the lower bracket is continuously in contact with the composite spring, removing the gap between the composite spring and the bracket.

2. The bracket apparatus according to claim 1 , wherein
the U-bolt passes through the lower and upper brackets, and then an end portion thereof is protrudingly formed upwards from the upper bracket; and
the nut is fastened to the end portion of the U-bolt to contact with an upper surface of the upper bracket.

3. The bracket apparatus according to claim 1 , wherein the elastic member includes a plurality of compression springs, first and second end portions of each of which are supported by the lower and upper brackets.

4. The bracket apparatus according to claim 1 , wherein the lower and upper brackets have installation grooves formed in respective upper and lower surfaces thereof for installation of the elastic member, first and second end portions of the elastic member being respectively fitted into the installation grooves.

5. The bracket apparatus according to claim 1 , wherein
the upper bracket has an insertion groove formed in a lower surface thereof wherein a portion of an upper portion of the lower bracket is inserted into the insertion groove; and
the portion of the upper portion of the lower bracket is inserted into the upper bracket through the insertion groove.
