Abstract: A slider for a slide fastener with an automatic locking mechanism comprises a small number of components and hence can be assembled and operated with ease. A slider body of the slider has a receiving hole for receiving a resilient plate running in parallel with a guide groove and arranged in the upper wing plate of the slider body. The receiving hole has an enlarged open section arranged at the side of a rear opening and communicating with the guide groove to a claw receiving hole, and is formed to have a narrow tubular shape above a guide post. A wide groove is arranged along a lateral side of the receiving hole with a gap therebetween. A through hole is arranged to perpendicularly cross the receiving hole at the middle thereof.

Abstract: A first extension member has a head coupled to a first zipper head and a tail having a male connector and an elongated generally flat intermediate portion between the head and the male connector. A second extension member has a head coupled to a second zipper head and a body with a female connector that receives and locks the male connector and receives and permits free sliding movement of the elongated flat intermediate portion.The female connector prevents removal of the male connector therefrom to prevent opening the zipper beyond a predetermined position based on the length of the elongated intermediate portion. Because the male connector is positioned generally at the end of the tail and the elongated intermediate portion is generally flat, the tail may slide freely within the female connector between the head and the male connector so that the zipper is therefore not locked in any fixed position.

Abstract: A one-piece, tamper-resistant fastener for attaching one item to another is described. The fastener is particularly suited for attaching an item such as a ski coupon to a skier's garment. The attachment mechanism of the fastener is designed to allow a user to attach both items to the fastener, and thus the items to each other, in one action. The fastener is made of a single piece of plastic material, preferably polypropylene, which is easily recycled, even with a typical ski coupon attached. The one-piece fastener may alternatively be made using a biodegradable material.

Abstract: In a die-casting slide fastener slider having a plastically deformable, cantilevered pull-tab attaching lug on a slider body, the lug projects from an upper end of a guide post over an upper wing toward a rear end of the upper wing and terminates in a downward end projection spaced from the upper wing by a gap through which an attachment ring of a pull tab is threaded. The lug has a longitudinal hollow through its base to facilitate plastically deforming the lug to reduce the size of the gap after threading. In this structure, since first and second slide cores of a mold for die-casting the slide fastener slider can be inserted from the front and rear sides, it is possible to mold the lug without generating any parting line on its overall appearance.

Abstract: A slider of a slide fastener is free from any damage that may arise when a lug is deformed and springs back and an upper wing is protected against undesired deformation. A pair of rear lateral legs project downward from the lug. A gap is defined between the rear lateral legs and the upper wing. One or more longitudinal ribs are formed on the lower surface of the lug. If excessively pinching force is applied to the lug to close the gap, the upper wing is kept free from any local deformation because the rear lateral legs absorb the excessive force. Also, if the lug springs back, because the rear lateral legs restore their original positions, they are held in close contact with the upper wing.
