The present invention relates to a strap-actuated buckle, and more particularly, to a strap-actuated buckle capable of easily separating a male buckle locked from a female buckle by connecting a strap to a male buckle and pulling the strap.

The currently used buckle is mainly used for products such as mountaineering bags, clothing, and life jackets, and is a device for easily binding both ends of one strap or two straps such as belts, waistbands, and tightening straps. In general, since the buckles must be coupled to each other and fixed, it is common to consist of a female buckle and a male buckle. Accordingly, the female buckle and the male buckle are coupled to each other and locked, and have a structure in which a certain force is applied to release the locking. Conventionally, the structure of the female buckle and the male buckle is a commonly known structure in which the locking is released by pressing the locking portion of the male buckle fastened to the female buckle in a one-touch format.

Due to the convenience of attaching and detaching the buckle, it is becoming an essential configuration for firefighters or soldiers who use equipment that needs to be quickly attached or removed. In particular, it can be applied to backpacks and body armor used in firefighting equipment and military equipment. When taking off the body armor, the Velcro tape or buckle coupled to the front or side can be directly released by hand to put on and take off the body armor. However, the method of releasing the locking of the plurality of coupling parts directly by hand has a problem in that it is difficult to take off easily in an emergency situation such as a training or exhibition situation, which interferes with activities. In addition, in case of injury, there is a problem in that time is wasted to release the complex coupling in an emergency situation in which first aid measures or transport must be quickly taken.

To solve this problem, a number of techniques have been proposed. In particular, Patent No. 2232808, the most recently proposed technology, relates to a one-touch buckle, which includes a buckle body composed of a female buckle and a male buckle, and an unlocking body connected to the buckle body with a wire to release the locking of the buckle body. In order to release the locking of the male buckle, a hinge portion is formed at the front end of the male buckle, and a one-touch buckle in which the locking is released is proposed by pulling a wire hanging from the elastic unlocking portion formed with the hinge portion.

However, in the case of the above technique, when the hinge part is formed at the front end and the wire connected to the unlocking part is pulled, a concentrated load is generated on the hinge part at the front end, and problems such as easy breakage may occur.

In addition, since the wire uses a wire for a breaker, there is a problem in that the range in which the line can be pulled is limited.
