Length adjustment apparatus

Abstract

The present invention relates to a length adjustment apparatus including a fixed housing having a central panel with a through-hole; and a rotatable housing having a rotational shaft to be inserted into the through-hole of the fixed housing, and which is coupled to the fixed housing such that the rotatable housing is rotatable in the forward and reverse directions relative to the fixed housing. A string is inserted into a first string passage hole formed at one side of either the fixed housing or the rotatable housing, taken up at a winding portion formed at the rotational shaft, and extracted through a second string passage hole formed at the other side of either the fixed housing or the rotatable housing, such that the string is taken up at the winding portion and released from the winding portion when the rotatable housing rotates in the forward and reverse directions. In the coupled parts of the fixed housing and the rotatable housing, a protrusion is formed at one of either the fixed housing or the rotatable housing and a groove is formed at the other one of the fixed housing and the rotatable housing. Whereby, a string adjustment apparatus with a simpler structure which enables for the convenient and effective adjustment of string length can be obtained.

Description

technical field [0001] The present invention relates to a rope length adjusting device, more specifically, relates to a rope length adjusting device which has a simpler and simpler structure and can adjust the length of the rope more conveniently and effectively. [0002] This application claims the priority of Patent Application No. 10-2008-0065205 filed with the Korean Patent Office on July 7, 2008, the contents of which are fully incorporated in this specification. Background technique [0003] Generally, jackets, sportswear, hats, etc. are equipped with adjustment ropes (hereinafter referred to as "ropes") to adjust the waist or head circumference according to the wearer's physical condition after wearing, and these ropes usually have fixed parts that move along the rope at their ends. Fixtures to maintain a certain length. [0004] The clamp passes through the rope at its central part, and is tightly attached to the rope to prevent it from moving along with the rope. T...

Problems solved by technology

[0005] However, when the clamp adjusts the length of the rope, the user should adjust it one by one, which is very cumbersome, and the entire length of the rope remains the original length, so the remaining parts will cause inconvenience or become entangled.

[0006] Also, since it is difficult to separate the string and the clip, there is a problem that the clip collides with the inside of the washing machine during laundry, causing damage or the washing machine breaks.
