Description

Double-deck slide fastener, the two pull head men and women trousers of single slide fastener

The utility model relates to the slide fastener that sealing process is played at crotch Qianmen, men and women's trousers station.

The accessory one that sealing process is played at crotch Qianmen, men and women's trousers station is a clasp, the 2nd, and slide fastener.The method of sealing, the one, use clasp to buckle, the 2nd, draw with slide fastener.Present most of trousers all are to have two: one with this accessory of slide fastener, and slide fastener is in use convenient and swift than clasp, the 2nd, install in process that the slide fastener ratio is stitched a button, the buttonhole labor and material saving, to such an extent as to also imitating male trousers, slacks change the slide fastener sealing of crotch Qianmen, station into by the sealing of side position clasp.The advantage of slide fastener has won liking of people, and slide fastener has played great role on trousers, is the greatest problem that exists at present but in use slide fastener is perishable.The slide fastener at position, trousers Qianmen is all the highest positions of accessory utilization rate of trousers, and slide fastener damages opening repeatedly in the closure easily, and the position of damage is based on slider of zipper fastener and slide fastener, and slider of zipper fastener decreases the drawing of cup slide fastener and do not go up, and slide fastener damages then that slider of zipper fastener draws motionless.The trousers Qianmen is in a very obvious position again, as just in use, runs into above example and makes the people rather awkward.

The utility model solve exactly crotch Qianmen bad slider of zipper fastener of slide fastener draw motionless, the problem that the bad slide fastener drawing of slider of zipper fastener is not gone up.

The utility model is two kinds of independently methods.The utility model is achieved in that first method is on the basis of existing slide fastener a secondary slide fastener to be installed again, becomes double slide fastener, slide fastener and outer slide fastener in double slide fastener divides.When double slide fastener is installed 2 requirements are arranged, when at first inside and outside two slide fasteners are overlapping, will stagger the mutually slide fastener distance of a sprocket of two slide fasteners, sprocket is the parallel shape arranged side by side of dividing right and left, and mainly is to prevent that bidentate is folded mutually, and thickness gate increases before the crotch, and it is uncomfortable to wear.Outer slide fastener prolonged 25 millimeter than interior slide fastener to the below of trousers when secondly inside and outside slide fastener was installed, and the pull head of inside and outside two slide fasteners is separated up and down, did not overlap on the point, also was to avoid trousers thickness to increase, and wore uncomfortable.About 5 millimeters of the thickness of a pull head, it is exactly 10 millimeters that two pull heads overlap, and two overlapping thickness that increase trousers greatly of pull head are unfavorable for dress.When so two layers of slide fastener are installed, the one, sprocket will separate, and two is that the slider of zipper fastener of two slide fasteners will stagger, and two layers of slide fastener have been arranged, and in use outer slide fastener break, and in addition interior slide fastener is very practical.Second method is the two pull heads of single slide fastener.Specific embodiments is: pull head of many installations on a slide fastener, in use, a pull head has been broken, and also has a standby pull head.The installation method of two slider of zipper fasteners is vertical arrangement up and down.

The utility model is compared with prior art, and advantage is to provide convenience to the consumer not influencing under the trousers situation attractive in appearance.A slide fastener in use only is installed on the trousers, just in case bad, just not easy to handle, two slide fastener situation differences have been arranged, the user can in time solve problem with the second slide fastener.Equally, the slide fastener of a pull head, pull head has been broken, and also is anxious but unable to do any thing, and the slide fastener of two pull heads is arranged, and the consumer just can start second pull head, goes on the street in safety.Double slide fastener, the trousers of two pull heads are a a progressive step than the trousers of single slide fastener, single pull head, use relieved when making the people buy the double slide fastener or the trousers of two pull heads.

The utility model is just added a slide fastener or is added a pull head on existing basis, method is simple.
