Abstract
In a curved spring configured to generate, based on a relative approaching displacement of the one-side bearing section and the other-side bearing section in an approach/separation direction, an urging force in a separation direction in which a one-side bearing section and an other-side bearing section are separated from each other, a linear elastic body is provided to extend on a closed curve, which includes a one-side portion arranged along a circumferential direction of the one-side bearing section and an other-side portion arranged along a circumferential direction of the other-side bearing section, and to constitute elastic sections of two lines between the one-side portion and the other-side portion.
Claims11
A curved spring comprising:
- an inner-side linear elastic body extending on a closed curve, which includes a one-side portion arranged along a circumferential direction of a one-side bearing section and an other-side portion arranged along a circumferential direction of an other-side bearing section so as to constitute elastic sections of two lines between said one-side portion and said other-side portion, wherein the curved spring generates, based on a relative approaching displacement of said one-side bearing section and said other-side bearing section in an approach/separation direction, an urging force in a separation direction in which said one-side bearing section and said other-side bearing section are separated from each other, and
- an outer-side linear elastic body extending on a closed curve, which includes a one-side portion arranged along a circumferential direction of the one-side bearing section and an other-side portion arranged along a circumferential direction of the other-side bearing section so as to constitute elastic sections of two lines between said one-side portion and said other-side portion, wherein the curved spring generates, based on a relative approaching displacement of said one-side bearing section and said other-side bearing section in an approach/separation direction, an urging force in a separation direction in which said one-side bearing section and said other-side bearing section are separated from each other,
- wherein the inner-side linear elastic body has contact with outer circumferential surfaces of the one-side bearing section and the other-side bearing section, and the outer-side linear elastic body surrounds the inner-side linear elastic body, and
- wherein each of the inner-side linear elastic body and the outer-side linear elastic body is formed from a single piece of linear material, has opposite ends, and includes a discontinuous portion in the one-side portion thereof or the other-side portion thereof.

A curved spring comprising:
- an inner-side linear elastic body extending on a closed curve, which includes a one-side bearing portion forming a portion of a one-side bearing section and an other-side bearing portion forming a portion of an other-side bearing section so as to constitute elastic sections of two lines between said one-side bearing portion and said other-side baring portion, wherein the curved spring generates, based on a relative approaching displacement of said one-side bearing section and said other-side bearing section in an approach/separation direction, an urging force in a separation direction in which said one-side bearing section and said other-side bearing section are separated from each other, and
- an outer-side linear elastic body extending on a closed curve, which includes a one-side bearing portion forming a portion of the one-side bearing section and an other-side bearing portion forming a portion of the other-side bearing section so as to constitute elastic sections of two lines between said one-side bearing portion and said other-side baring portion, wherein the curved spring generates, based on a relative approaching displacement of said one-side bearing section and said other-side bearing section in an approach/separation direction, an urging force in a separation direction in which said one-side bearing section and said other-side bearing section are separated from each other,
- wherein the inner-side linear elastic body has contact with outer circumferential surfaces of the one-side bearing section and the other-side bearing section, and the outer-side linear elastic body surrounds the inner-side linear elastic body, and
- wherein each of the inner-side linear elastic body and the outer-side linear elastic body is formed from a single piece of linear material, has opposite ends, and includes a discontinuous portion in the one-side portion thereof or the other-side portion thereof.
