Abstract

A cord lock includes a main body having front and rear walls and two side walls, an elongated hole, and an inclined portion formed in an inner surface of the side walls; and an operating button having front and rear wall side operating portions arranged on the front wall and the rear wall, respectively, a connecting portion integrally connected to the front and rear wall side operating portions through the elongated hole, a biasing device biasing the front and rear side operating portions to the one side opening to cooperate with the inclined portion, and a gear-shaped engagement portion adapted to pinch the band inserted into the tubular shape. The operating button has a pivot portion, wherein a distance between an axial end of the pivot portion and a shaft end supporting the gear-shaped engagement portion is narrower than a thickness of the gear-shaped engagement portion.

First claim

What is claimed is:

1. A cord lock comprising:
a main body which is formed into a tubular shape adapted to insert a band from one side opening of the tubular shape into another side opening, and having front and rear walls and two side walls, an elongated hole arranged so as to face the front and rear walls and extending in a direction of a tube, and an inclined portion formed in an inner surface of the side walls and expanding toward a depth; and
an operating button having a front wall side operating portion and a rear wall side operating portion arranged on the front wall and the rear wall, respectively, a connection portion integrally connected to the front and rear wall side operating portions through the elongated hole, a biasing device biasing the front and rear wall side operating portions to the one side opening to cooperate with the inclined portion, and a gear-shaped engagement portion which is adapted to pinch the band inserted into the tubular shape,
wherein the operating button protrudes in a direction from at least one of the front wall side operating portion and the rear wall side operating portion toward the other thereof, and has a pivot portion in which the gear-shaped engagement portion is axially supported, a distance between an axial end of the pivot portion and a shaft end supporting the gear-shaped engagement portion arranged in another side or a support portion being narrower than a thickness of the gear-shaped engagement portion, so that the distance is expanded by an elastically deforming portion which is arranged in the operating button, and the gear-shaped engagement portion is capable of passing through.

2. The cord lock according to claim 1 , wherein the elastically deforming portion is the connection portion.

3. The cord lock according to claim 1 , wherein the elastically deforming portion is the support portion.

4. The cord lock according to claim 1 , wherein the biasing device is a coil spring, and includes a come-off prevention portion so as to partly close an opening end as well as a seat which receives a corresponding end portion of the coil spring in the another side opening, such that an open portion other than a closed portion of the come-off prevention portion is set to an insertion portion of the band.

5. A cord lock comprising:
a main body which is formed into a tubular shape adapted to insert a band from one side opening of the tubular shape into another side opening, and having front and rear walls and two side walls, an elongated hole arranged so as to face the front and rear walls and extending in a direction of a tube, and an inclined portion formed in an inner surface of the side walls and expanding toward a depth; and
an operating button having a front wall side operating portion and a rear wall side operating portion arranged on the front wall and the rear wall, respectively, a connection portion integrally connected to the front and rear wall side operating portions through the elongated hole, a biasing device biasing the front and rear wall side operating portions to the one side opening to cooperate with the inclined portion, and a gear-shaped engagement portion which is adapted to pinch the band inserted into the tubular shape,
wherein the operating button has a support piece which is provided in the connection portion, and a pivot portion which is arranged in the support piece and protrudes toward one of the front wall side operating portion and the rear wall side operating portion to axially support the gear-shaped engagement portion, a distance between an axial end of the pivot portion and a shaft end supporting the gear-shaped engagement portion arranged in another side or a support portion being narrower than a thickness of the gear-shaped engagement portion, the distance being expanded by an elastically deforming portion which is arranged in the operating button to pass the gear-shaped engagement portion.
