Abstract

A cord lock includes a female member including first cord insertion portions through which a cord can be inserted to pass; a male member capable of moving in and out from an opening of the female member, and including second cord insertion portions through which the cord inserted to pass through the first cord insertion portions can pass; and an urging device provided between the female member and the male member to provide an urging force in a direction wherein the male member protrudes from the opening of the female member. The second cord insertion portion of the male member and the urging device are located adjacent to each other, and on opposed faces of the female member and the male member along an insertion direction of the cord, straight portions which can carry out at least a line contact are provided.

First claim

What is claimed is:

1. A cord lock, comprising:
a female member including a pair of first cord insertion portions facing each other in a first direction and adapted to receive a cord therethrough, the female member having a cylindrical shape including an opening at least at one end of the female member and a bottom portion at another end of the female member facing the opening, the bottom portion including a pair of through portions arranged on an inner side of the corresponding first cord insertion portions;
a male member supported to enter into and out from the opening of the female member, and including
a pair of second cord insertion portions facing each other to communicate with the first cord insertion portions and adapted to receive the cord inserted through the pair of first cord insertion portions, and
a pair of flange portions overlapping the female member when the female and male members are assembled, and entering into the pair of through portions, respectively; and

an urging device provided between the female member and the male member to provide an urging force in a direction wherein the male member protrudes from the opening of the female member,
wherein the pair of second cord insertion portions of the male member and the urging device are situated adjacent to each other, and
the female member and the male member include faces extending along the first direction and having straight portions to line contact each other.

2. The cord lock according to claim 1 , wherein the male member further comprises:
a cord chamber arranged between the pair of second cord insertion portions and adapted to receive the cord,
a spring chamber housing the urging device, and
a partition wall provided between the cord chamber and the spring chamber to partition the cord chamber and the spring chamber side by side in a plan view along the first direction.

3. The cord lock according to claim 2 , wherein the urging device is a coil spring, and
the partition wall is partially cut to receive the coil spring.

4. The cord lock according to claim 2 , wherein the female member includes a side wall extending from the bottom portion to define the opening, and has a hexagonal shape.
