Abstract
The invention relates to an apparatus (1) for locking a cord (2), a wire, a tube or any other bendable member into a locking position with a locking portion. The locking portion (3) has at least one open slits shaped receiving cavity (5) defined at one end of the locking portion, the cavities having an opening that is facing away from a portion (7) of the cord that is under tension and the cavity having a width that is less than a diameter of the cord so that the portion (7) that is under tension and a portion (8) of the cord that is received within the receiving cavity are substantially perpendicular to one another.
Claims9
An apparatus for locking a cord into a locked position, comprising:
- a locking member having a first end and an opposite second end, both ends defining n opening extending through the locking member;
- the locking member further having an open slit at the first end thereof;
- the cord having a first end portion and an opposite second end portion, the cord having a diameter D;
- the open slit being formed in the locking member and having:
- an outermost diverging wall portion that has a greatest width that is greater than the diameter D;
- a bottom wall portion with a minimum width that is less than the diameter D;
- a central wall portion formed as substantially parallel, opposing side walls of the locking member and connecting the outermost diverging wall portion and the bottom wall portion, the opposing side walls having a substantially constant separation that is wider than the bottom wall portion;
- the open slit being adapted to receive the first end of the cord through the outermost diverging wall portion, along the central wall portion, and at least partially disposed into the bottom wall portion thereby locking the cord;
- and
- the first end of the cord being substantially perpendicular to the second end of the cord when the first end of the cord is at least partially disposed within the bottom wall portion of the open slit.

A cord locking device comprising:
- a mainly cylindrical locking member having an outer wall, a mainly open interior within the outer wall, and at least a first open end for receiving at least one cord, each cord having a cord diameter and a first end and a second end;
- a pair of substantially longitudinally extending slits formed in and through the outer wall of the locking member, each slit having:
- a guiding wall portion that has a greater width that is greater than the cord diameter;
- a bottom wall portion with a minimum width that is less than the cord diameter;
- a central wall portion that is wider than the bottom wall portion and is formed as substantially parallel, opposing side walls of the locking member and connecting the outermost and innermost wall portions of the locking member;
- each slit thereby being adapted to receive a respective one of the cords through the respective guiding wall portion, along the respective central wall portion, and at least partially into the respective bottom wall portion, the respective bottom wall portion and respective central wall portion together cooperate to thereby secure each cord in a locked position;
- the first end of each secured cord, in the locked position, being substantially perpendicular to the second end of the cord.

An apparatus for locking a cord into a locked position, comprising:
- a locking member having a first end and an opposite second end, both ends defining an opening extending through the locking member;
- the locking member defining an open slit at the first end thereof, the open slit having a width;
- the cord having a first end portion and an opposite second end portion, the cord having a diameter D that is greater than the width of the open slit;
- the open slit being adapted to receive the first end of the cord having a bottom and parallel side walls extending upwardly therefrom so that the open slit has a width V between the parallel side walls that is about half the diameter D of the cord, the parallel side walls having a length B that is about the same or greater than the diameter D of the cord;
- the first end of the cord being substantially perpendicular to the second end of the cord when the first end of the cord is disposed within the open slit.
