Fastener stringer, slide fastener, and objects with attached fasteners

Abstract

For fastener stringers (4, 44, 64), paired left and right fastener tapes (2, 42, 62) comprise a main body of the tape (2a, 42a, 62a) and element attachment part (2b, 42b, 62b) that is disposed on one edge of the main body of the tape (2a, 42a, 62a). A row of elements (3, 43, 63) is attached to the element attachment part (2b, 42b, 62b). Electrically conductive yarn is used for the main structural yarn lines (11, 12) that configure the fastener tapes (2, 42, 62), and the fastener tapes (2, 42, 62) have conductivity that can shield electromagnetic waves. Moreover, the pair of fastener tapes (2, 42, 62) have electrically conductive tape-contacting parts (16, 49, 62c) that closely contact the fastener tape (2, 42, 62) on the other side when the rows of elements (3, 43, 3) are interlocked, and the rows of elements (3, 43, 63) in an engaged state are covered by the tape-contacting parts (16, 49, 62c) when the tape-contacting parts (16, 49, 62c) closely contact each other. Such fastener stringers (4, 44, 64) can prevent leakage of electromagnetic waves from the rows of elements (3, 43, 63) in an engaged state and can reliably shield electromagnetic waves.

Description

technical field [0001] The present invention relates to a fastener stringer capable of shielding (shielding) electromagnetic waves, a slide fastener constructed using the fastener stringer, and a fastener attachment to which the slide fastener is attached. Background technique [0002] In recent years, information and communication equipment and digital electronic equipment have been popularized, but on the other hand, the problem of electromagnetic waves emitted by these equipment has also been paid attention to. For example, it is known that electromagnetic waves emitted from communication equipment etc. cause various equipment to malfunction or fail. [0003] In addition, since electromagnetic waves are emitted from information devices such as OA devices, for example, by receiving electromagnetic waves from such information devices externally, personal information and corporate confidential matters can be stolen. In this way, electromagnetic waves cause various disadvant...

Problems solved by technology

[0020] However, in such conventional slide fasteners and slide fastener chains, in a state in which the left and right fastener elements are meshed, there is formed between the left and right fastener elements and between the fastener elements adjacent to each other in the tape length direction. lots of tiny gaps

[0021] Therefore, in conventional slide fasteners and fastener chains, even if the fastener tape and the fastener elements are conductive in order to obtain an electromagnetic wave shielding function, there is still a problem that electromagnetic waves leak through a large number of gaps formed in the meshed element rows.
