Description

Curtain rope safety anchor

The present invention relates to a curtain cord safety anchor, especially a curtain cord safety anchor which can facilitate the separation of the two-phase combined drawstring when the child's neck is wrapped by the drawstring.

According to the curtain system, it provides the functions of building shade, privacy and decoration. The curtains are divided into Roman blinds, roller blinds and venetian blinds according to their types, shapes and functions. The existing curtains are mainly ropes. Or a drawstring such as a bead chain to control the opening and closing of the curtain.

In general, the drawstrings such as ropes or bead chains are formed into a ring shape, and are laid down so that the users of different heights can easily grasp the looped drawstring and pull the upper and lower directions to drive. The curtain is rolled up, or the function of shielding the window is released downward. Since the curtain has a drawstring, the child can easily construct the curtain drawstring and use the drawstring as a play toy, since the looped rope is mostly made of a strong rope. Or a bead chain, and easy to produce entanglement, knotting phenomenon, when the child plays, if the ring rope is inadvertently wrapped around the neck, in the panic to struggle to untie the ring rope The more the rope is struggling, the more tightly it is wrapped around the child's neck, causing the child to be shackled.

Therefore, based on the prevention of children's resilience, countries have developed safety regulations for the drawstrings or bead chains of the curtains. Therefore, the industry has developed a collection of bundles that can combine the activities of the bottom end of the drawstring. For the solids, please refer to the "Curtain Drawstring Safety Pulling Device" of China's Announcement No. I414264, which basically consists of a dimple-like collecting cup, and the inner bottom is provided with a perforation downward to provide a top end of the pulling element. The coupled wire hoop body is inserted and inserted, and the inner ring side of the wire hoop is oppositely displaced from the bottom surface of the cup body, and the radial locking of the pair of pull ropes is radially locked, thereby forming a relay capable of fully transmitting the pulling force, and Very time to break the rope quickly, so that the moment is bright and sensitive.

In addition, please refer to the "Safety Cable Buckle for Curtain Drawstrings" of China's Announcement No. M440740, and the "Safety Glue for Curtain Drawstrings" of China's Announcement No. M322783, which is mainly composed of left and right shells. The utility model has the corresponding joint block and the joint groove between the left and right shells, and has a bottom hole on the bottom surface of the left and right shells, so that the two to four drawstrings of the curtain can be respectively secured by the safety bundle. The through holes of the left and right top surfaces of the device are inserted and fixed, and a main rope having a knot extends through the bottom hole, and the pulling force is combined by the clamping force of the left and right shells to urge all the ropes. The multiple drawstrings can be combined by a safety buncher and have the characteristics of being able to automatically decompose and fall off when subjected to excessive external force.

The above two patents are designed to achieve a load that is subjected to excessive external force (for example, when a child's neck is accidentally pulled by a drawstring), the left and right housings can be automatically disassembled and the stability ring can be loosened. The intended purpose of releasing the drawstring neck is that the left and right shells are respectively made of different molds, so the molds of the left and right shells must be made in the manufacture, and the shell of the safety beamer is caused.
