Abstract

The invention relates to a curtain structure having a safety function. Primarily, an accommodating space formed between a fixing seat and an assembling seat is provided with a bead chain seat, an elastic member and a first transmission member within a cavity of the bead chain seat. Thereby when a child exerts force to pull a bead chain which wraps around the neck, a conical head of the first transmission member and a conical receiving slot of a second transmission member mounted on the assembling seat can guide the first transmission member to generate a thrusting force toward the direction of the bead chain seat so that the first transmission member is retracted into the cavity of the bead chain seat and the bead chain seat and the bead chain cord can be separated from the accommodating space, and then the bead chain cord can be unwound. When the bead chain seat or the like is to be returned to the accommodating space, the elastic member and the first transmission member are sequentially inserted into the cavity of the bead chain seat, and the bead chain seat and the bead chain cord are placed into the accommodating space. Then the elastic member presses the first transmission member to reset the first transmission member to be engaged and positioned with the second transmission member. Accordingly, it can easily achieve the effect of placing the bead chain seat and the bead chain cord into the accommodating space again.

Description

Curtain structure with safety detachment

The present invention relates to a curtain structure with safety detachment, in particular to a pearl chain disc which can be pulled off by force to prevent children from being strangled by the pearl chain rope, and the pearl chain disc can be assembled back to the pearl chain. Curtain structure for accommodating space.

According to the curtain, the curtain has the functions of providing building shading, ensuring privacy and decoration. The existing curtains such as Roman curtains and roller blinds mainly use a pull rope to control the opening and closing of the curtain body. The curtain ropes of these curtains are usually hoop-shaped, so as to facilitate users to hold the ropes to drive the curtain body to roll up and lower. Because the curtain rope is draped, children can easily construct the curtain rope and use the rope as a play toy. Since the loop rope is mostly composed of a strong rope body or a bead chain, etc. It is prone to entanglement and knotting. When children play, if they accidentally let the drawstring around the neck, they struggle in panic and want to untie the drawstring, but the drawstring struggles more and more tightly around the child. Neck, which can cause strangulation in children.

Therefore, in order to avoid the danger of the curtain rope pulling children by the governments of various countries, the curtain manufacturers are required to have a safety structure capable of releasing the curtain rope. Please refer to the “Belt curtain driver structure with safe disengagement” of China's Announcement No. M530617. The pre-patent application filed by the inventor of this case mainly includes a base assembled with the outer tube of the curtain. A bead chain turntable is provided corresponding to the set. The bead chain turntable is provided with a plurality of bead insertion grooves for the bead chain to enter, and a cover is pivotally arranged on the base. The cover limits the bead chain to the bead. For those who rotate on the chain turntable, the bead groove is provided with an angle inclined radially, so that when the bead chain is pulled by force, it slides forward to push the cover off; thereby, the bead chain is made of beads. The chain turntable is detached to achieve the safety protection effect of preventing young children from going around the neck.

Although the “Bead curtain driver structure with safety detachment” of China ’s Announcement No. M530617 can achieve that when a child is pulled around by a bead chain and pulls the bead chain, the bead chain can be detached from the bead chain turntable in order to release the bead chain to the child The neck is tightly wound; however, because the outer curtains are generally assembled at high places, and the bases arranged at the ends of the outer curtains of curtains are mostly adjacent to the wall of the building, the pivotal protection of the bases When the cover is opened, it will touch the side wall of the building, which will limit the opening angle of the cover. Therefore, when the bead chain is detached from the bead chain turntable, it is often The cover cannot be fully opened due to the limit of the wall of the building on the side, and the unfavorable assembly conditions such as the base of the curtain outer tube is assembled at a high position, causing the user to install the bead chain that has fallen off to the bead chain turntable. Difficulty.

The reason is that the inventor still has the above-mentioned shortcomings in the implementation of the "Bead curtain driver structure with safe disengagement" in view of its previously developed China Bulletin No. M530617, which is based on his many years of manufacturing and design experience in related fields and It is supplemented by knowledge, and through various ingenuity, the invention has been developed.
