Description

Zipper {ZIPPER}

The present invention relates to a zipper, and more particularly, to prevent the zipper from being opened due to the separation of the coupling due to the pressure applied by the contents contained in the inside of the zipper, and at the same time, the zipper can be arbitrarily lowered when the zipper is closed. And a double slider assembly capable of being restrained.

In addition to the pockets of jumpers and pants, backpacks, bags, sneakers and boots use various types of zippers to lock the openings. The zipper was developed to alleviate the inconvenience of tying the straps with each use.The basic principle is that by pulling the center handle of the zipper, the teeth arranged in a row on the right and left side of the cloth tape are closed while the teeth are engaged with each other to close the opening. When it is lowered, the interlocking teeth are separated and the opening is opened.

Types of zippers include the visible zippers, concealed fasteners concealed in the seams, open fasteners, and other specially large and open handles. There are giant zippers with decorative or stone trim, waterproof flat zippers, and safety zippers that only need to be lifted by the zipper loop.

1 shows a conventional general zipper structure. As shown here, the zipper 100 is generally arranged in a form in which a pair of zipper tapes 120 made of a fabric material facing each other, each of these zipper tapes 120, a predetermined arrangement interval on the contact surface Coupling 122 having a tooth structure having a continuous coupling. On the line of the coupling 122, a slider 110 having a handle 114 on the upper side is coupled so that the pair of couplings 122 engage with each other in accordance with the forward and backward movements of the slider 110. Or separate to open and close the opening.

As shown in the figure, holding the handle 114 and ascending the slider 110 causes the pair of couplings 122 located above the slider 110 to be separated from each other in the body 112 of the slider 110. When the slider 110 is lowered downward, the coupling 122 coupled to each other is separated from each other while passing through the body 112 of the slider 110.

However, in the conventional zipper having such a structure, when the zipper is closed due to a lot of contents inserted into the zipper in order to seal the zipper, the slider is raised while pressing the opened zipper tape with both hands. As a lot of force enters and the zipper is opened while the coupling is released by the pressure of the contents, the contents protrude out or the zipper cannot be used again.

In order to solve this problem, the applicant has developed a new type of zipper and filed on July 4, 2000 (registered on September 19, 2000, domestic utility model registration No. 205027). In this Utility Model Registration No. 205027, the elasticity of the contents accommodated in the zipper is maintained by a zipper coupling that is coupled to each other during the closure of the zipper, while allowing the zipper to be easily closed with less force. A zipper is disclosed that can prevent the zipper from being opened.

In the case of this zipper, a zipper provided at one side of a pair of zipper tapes can be opened and closed by a forward and backward movement of a slider provided with a handle, wherein the slider has an extension portion at both sides of the body. One side of the furnace is formed with a cutout, the inside thereof is formed with a guide rail coupler having a circular space portion, the guide rail coupler is slidably coupled to the guide rail formed at one end of the guide member in close contact with the bottom surface of the zipper tape It is characterized by the configuration as possible.

In the conventional zipper having such a configuration, since the guide rail coupler is coupled and the sliding guide rail merely serves to guide the sliding movement of the slider, safety guides for preventing opening such as safety zippers should be separately provided. This causes the manufacturing cost to rise.

The present invention for solving this problem prevents the coupling from being separated by the contents in the process of closing the zipper while the slider is sliding, and at the same time, the coupling state of the coupling is released and separated in a completely closed zipper state It is an object of the present invention to provide a zipper having a papermaking means that serves to prevent it.
