Description

Drawstring-free curtain retractor

The present invention relates to a cordless curtain retractor, and more particularly to a cordless curtain retractor that can surely prevent a child from being caught by a rope.

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. Pull the rope to control the opening and closing of the curtain.

In general, the drawstrings (or bead chains) of the curtains are formed into a ring shape and are laid down so that the users of different heights can easily grasp the drawstring and pull the upper and lower directions to take the scroll. The receiver drives the curtain body up and down, or releases the function of shielding the window 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 drawstring is composed of a strong rope, It is easy to produce entanglement and knotting. When a child plays, if the cord is inadvertently wrapped around his neck, and if he wants to struggle to untie the cord in a panic, the rope will become more and more tight. Wrapped around the child's neck, causing the child to stretch.

Therefore, based on the prevention of children's shackles, countries have established safety regulations for the drawstrings of curtains, such as the movable end of the drawstring, which is detachably attached to the bottom of the drawstring. When pulling the drawstring, the bottom of the drawstring can be separated to release the drawstring of the drawstring. However, in actual use, the puller is often not easy to fall off after the puller is pulled, or bundled. The combination and separation structure of the device is too cumbersome. When the child's neck is wrapped with a drawstring, it is difficult to calmly untie the force-carrying device under the panic condition, so that the situation of the child being pulled by the rope still occurs frequently.

The reason is that the present creator has in view of the fact that the existing drawstring retractor with a drawstring is prone to entanglement in the child's neck, resulting in the loss of children's shackles, etc., thanks to its many years of manufacturing and design experience and knowledge in related fields. And through many ingenuity, research and development of the existing curtain retractor, and research and creation of this creation.

The present invention relates to a cordless curtain retractor, the main purpose of which is to provide a cordless curtain retractor that can surely prevent a child from being caught by a rope.

In order to achieve the above-mentioned implementation purposes, the present author has developed the following cordless curtain retractor, which is mainly provided with a retractor main body, and the main system of the retractor includes a corresponding shaft seat and a lining cover, and The shaft seat and the lining cover have an accommodating space, and the shaft seat and the lining cover are formed with through holes at opposite sides thereof, and the two through holes are communicated with the accommodating space, and the accommodating space is a transmission rod is disposed in the space, and one end of the transmission rod is disposed on the shaft seat to be assembled with a cord retracting unit, and the other end of the transmission rod is provided with a worm wheel, and is disposed in the accommodating space.
