Abstract

A bodkin includes first and second holding plates, an operation plate and an elongated bar member. The second holding plate overlaps with the first holding plate. The operation plate is rotatably supported by the first holding plate with a part of the second holding plate disposed between the first holding plate and the operation plate. The bar member is connected to the first holding plate so that the operation plate is operable independently of the bar member. Use of the operation plate enables the bodkin to selectively take an opened state and a closed state. In the opened state, the two holding plates are apart from each other, providing a gap into which an end of a string can be inserted. In the closed state, the two holding plates are brought closer to each other, thereby pinching the end of the string between them.

First claim

The invention claimed is:

1. A bodkin, comprising:
a first holding plate including a base end portion and a first front end portion that are spaced apart from each other in a first direction;
a second holding plate including a second front end portion and a base end portion opposite to the second front end portion, the second front end portion being arranged to overlap with the first front end portion as viewed in a second direction extending along a thickness direction of the first holding plate and perpendicular to the first direction;
an operation plate including a base end portion rotatable relative to the first holding plate about a third direction perpendicular to both the first direction and the second direction, the operation plate being configured to switch between an opened state and a closed state, wherein in the opened state the first front end portion and the second front end portion are apart from each other and in the closed state the first front end portion and the second front end portion are in contact with each other; and
a bar member connected directly to the base end portion of the first holding plate and elongated in the first direction, the bar member being formed separately from the operation plate,
wherein the opened state is attained by the operation plate standing upright with respect to the first holding plate, and the closed state is attained by the operation plate overlapping with the first holding plate, thereby pressing the second holding plate toward the first holding plate, and
the bar member includes an elastically deformable body portion elongated in the first direction, and the body portion has a cross section that is greater in size in the third direction than in the second direction.

2. The bodkin according to claim 1 , wherein the base end portion of the second holding plate is supported by the first holding plate rotatably about the third direction,
the first holding plate is provided with a pair of upright pieces each disposed between the base end portion of the first holding plate and the first front end portion, the upright pieces being spaced apart from each other in the third direction and extending in the second direction, and
the base end portion of the operation plate is rotatably supported by the pair of upright pieces.

3. The bodkin according to claim 2 , wherein the pair of upright pieces are formed with holes, respectively, that are paired with each other in the third direction, and
the base end portion of the operation plate is provided with projecting portions that are spaced apart from each other in the third direction and fitted into the holes of the upright pieces, respectively.

4. The bodkin according to claim 2 , wherein the operation plate includes a front end portion opposite to the base end portion of the operation plate and includes an extending piece that extends from the base end portion of the operation plate and is capable of pressing the second holding plate, the extending piece extending in a direction intersecting a direction connecting the base end portion of the operation plate and the front end portion of the operation plate.

5. The bodkin according to claim 4 , wherein in the closed state the second holding plate is elastically pressed against the first holding plate by the extending piece.

6. The bodkin according to claim 1 , wherein the first front end portion is provided with a plurality of first teeth projecting toward the second holding plate and arranged at intervals in the third direction,
the second front end portion is provided with a plurality of second teeth projecting toward the first holding plate and arranged at intervals in the third direction, and
the plurality of first teeth and the plurality of second teeth are alternately arranged in the third direction.

7. The bodkin according to claim 1 , wherein the bar member includes a leading portion connected to the body portion, and the leading portion tapers with increasing distance from the body portion.

8. The bodkin according to claim 7 , wherein at least a part of the leading portion has a cross section that is greater in area than the cross section of the body portion.

9. The bodkin according to claim 1 , wherein the operation plate is arranged above the base end portion of the first holding plate and the base end portion of the second holding plate in the second direction.

10. The bodkin according to claim 1 , wherein the operation plate includes a front end portion opposite to the base end portion of the operation plate, and
in the opened state, the front end portion of the operation plate stands upright away from the bar member.
