摘要:
Disclosed are an intelligent anti-theft zipper and an intelligent anti-theft system for zippers. The zipper includes a zipper tape (1), a zipper head (2) and an intelligent anti-theft module (4). The intelligent anti-theft module (4) includes a control signal switch (40), an alarm unit (42) and a power supply (44). The control signal switch (40) includes a first switch component (401) and a second switch component (402) cooperating with each other. The first switch component (401) is fixed on the zipper head (2); the second switch component (402) is fixed on the zipper tape (1) or an article with the zipper, the installation position of the second switch component (402) corresponds to the position of the zipper head (2) when the zipper is fully closed. The control signal switch (40) generates and outputs a control signal to the alarm unit (42) to give an alarm when the first switch component (401) deviates from the second switch component (402) a predetermined distance. The system comprises the intelligent anti-theft zipper and an anti-theft terminal (6). The zipper and the system can timely detect the illegal opening of the zipper and give an alarm. ( Fig. 1 )
摘要:
The invention concerns a device for controlling the closed or open state of an article, the control device being in the form of an electronic circuit comprising a first closure system (9), comprising a first electrically conductive element (6) and a second electrically conductive element (7) that can be electrically connected to or disconnected from each other, at least the first element (6) comprising a hollow body (60); a power supply source (5) housed in the hollow body (60), a second closure system () comprising a first terminal () and a second terminal (). The control device also comprises a detection and signalling device comprising a detection module configured to be powered by the source (5) in the closed state of the first closure system (9) and to detect the open or closed state of the second closure system, and a signalling module configured to emit a signal depending on the open or closed state of the second closure system detected by the detection module.

A slide fastener of the present invention includes: a first fastener stringer; a second fastener stringer; and a slider which couples or separates the first and second fastener stringers, in which the second fastener stringer separated from the slider is inserted into the slider wherein the first fastener stringer and the second fastener stringer are coupled in a vertical direction. Accordingly, a row of fastener elements of the second fastener stringer separated from the slider is inserted into the slider by first and second fastening members when a fixing pin and an insertion pin are coupled in a vertical direction, and as a result, the coupling operation is convenient.

This slide fastener (1) is characterized in that the first and second main surfaces of the main body (21a, 51 a) of the engaging head (21, 51) of the fastener elements (20, 50) are flat surfaces that are orthogonal to the longitudinal tape direction and the pair of legs (23, 53) of the fastener element (20, 50) curve in a diagonal direction or extend at a slant with respect to the first and second main surfaces of the main body of the head (21a, 51 a). As a result, this slide fastener (1) has a different external appearance from previous slide fasteners and is able to stably achieve strength with respect to transverse pulling and strength with respect to thrusts that are equivalent to or greater than previous slide fasteners.

摘要:
The slide fastener (1, 2) of the invention has separable bottom end stop (30, 40), and the separable bottom end stop (30, 40) has at least an insert pin (31, 41) and a box pin (32, 42). The insert pin (31, 41) has an escape portion (31b, 41c) provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin (31, 41) decreases in the direction of the tape width toward the side edge that faces the box pin, the escape portion being positioned in the front end corner portion of a first surface of the insert pin (31, 41), the corner portion being positioned along the edge that faces the box pin. This allows the escape portion (31b, 41c) of the insert pin (31, 41) to function as an interference prevention means, can efficiently prevent chain failure in an element row (12) when the slide fastener (1, 2) is bent into a U-shape, and can maintain stable engaging.
