隱形拉鏈的拉頭 Invisible zipper slider

本創作係有關一種隱形拉鏈的拉頭，尤指一種用於反覆鏈合或分離兩條鏈帶的隱形拉鏈的拉頭結構改良。 The present invention relates to a slider for a concealed zipper, and more particularly to a slider structure for a concealed zipper for reversing or separating two chain straps.

現在常規的隱形拉鏈包括二鏈帶，及一連接住二鏈帶的拉頭，每片鏈帶上各自有一列鏈牙，通過使用者操作拉頭的移動，能夠帶動二鏈帶的鏈牙相互鏈合或分離。其中，習知拉頭的結構參見圖1所示，其包括一基體10、一擋針20及一拉片30，該基體10用於沿成列的鏈牙滑動，並使兩列相對的鏈牙相互嚙合或分離，該擋針20通過一銷釘40轉動地連接在基體10上，該擋針20上設置有供一銷釘40穿過的通孔201，並在擋針20的前端成型有一針尖202，而基體10中央的前部對應針尖202處設有一鎖止孔101，使擋針20後端通過一彈簧50的常態頂推，使其針尖202穿過鎖止孔101並***相互嚙合的鏈牙之間，使拉頭無法任意滑動，防止隱形拉鏈不慎滑開。參閱圖2所示，當使用時需要先拉動拉片30，通過拉片30拉起擋針20的前端，使針尖21從鏈牙之間退出，如此就能夠滑動拉頭，使二鏈帶的鏈牙彼此嚙合或分離。 Nowadays, the conventional concealed zipper comprises a two-chain belt, and a slider connecting the two-chain belts, each of which has a chain of fasteners on each of the chain belts, and the movement of the sliders by the user can drive the fastener elements of the two-chain belts to each other. Chaining or separation. The structure of the conventional slider is shown in FIG. 1 , which includes a base 10 , a stopper 20 and a pull tab 30 for sliding along the rows of fastener elements and making the two rows of opposite chains The teeth are meshed or disengaged, and the needle 20 is rotatably coupled to the base 10 by a pin 40. The needle 20 is provided with a through hole 201 through which a pin 40 passes, and a tip is formed at the front end of the stopper 20. 202, and the front portion of the center of the base 10 is provided with a locking hole 101 corresponding to the needle tip 202, so that the rear end of the needle 20 is pushed through the normal state of a spring 50, so that the needle tip 202 passes through the locking hole 101 and is inserted into the intermeshing. Between the fastener elements, the slider can not be arbitrarily slid, preventing the hidden zipper from slipping open. Referring to FIG. 2, when used, the pull tab 30 needs to be pulled first, and the front end of the retaining pin 20 is pulled up by the pull tab 30, so that the needle tip 21 is withdrawn from between the fastener elements, so that the slider can be slid to make the two-chain strap The fastener elements mesh or separate from each other.

然而，使用者拉動拉片30的方式可能有偏斜施力的動作，因此當上述的擋針20被拉片30拉起時，擋針20的前端容易因為欠缺左右二側的側擋力量，導致擋針20的前端左右偏擺，造成擋針20前端的針尖21偏向變形，或脫離鎖止孔101，以致不能再正確的***相互嚙合的鏈牙之間，更嚴重的情況會發生擋針20前端斷裂，如此極為影響到隱形拉鏈的使用壽命。 However, the manner in which the user pulls the pull tab 30 may have a biasing action. Therefore, when the above-mentioned stopper 20 is pulled up by the pull tab 30, the front end of the stopper 20 is likely to lack the side restraint force on the left and right sides. The front end of the needle 20 is yawed to the left and right, causing the tip 21 of the front end of the needle 20 to be deformed or disengaged from the locking hole 101, so that it can no longer be correctly inserted between the intermeshing elements, and the needle is more likely to occur. 20 front end breaks, which greatly affects the service life of the concealed zipper.

本創作之目的在提供一種隱形拉鏈的拉頭，透過拉頭的結構改良，使擋針的二側具有防止左右偏擺的結構，進而防止拉片扭轉時擋針發生左右偏移變形或斷裂的情況，防止擋針尖端脫離拉頭基體上的鎖止孔造成拉頭損壞，達到提高隱形拉鏈的拉頭的抗扭強度與使用壽命的目的。 The purpose of the present invention is to provide a slider for a hidden zipper, which is improved in structure by the slider, so that the two sides of the needle have a structure for preventing the left and right yaw, thereby preventing the needle from being deformed or broken when twisted and twisted.
