Slider for slide fastener with locking mechanism

摘要

The present invention provides a slider with a simple locking mechanism which allows the slider to be operated easily and exerts its locking function accurately. In the slider of this invention, a recess (11) is made in the center of an upper wing plate (5) of a slider body (1) thereof and engaging posts (17) are provided on the front and back of the slider body (1). Two pawl holes (13) are provided in a bottom portion (12) of the recess (11) and supporting pieces (14) are provided on the right and left sides so as to be erected. Guide grooves (16) are provided in side walls (15) of the recess (11). A pawl body (2) includes locking pawls (24) provided on the right and left of a bottom face thereof in which a top face (21) thereof is formed in a mountain shape and their phases are deviated by half pitch and guide protruding portions (26) protruding from the side walls (25). A pull tab (3) has a pintle (29) on an end thereof and a cam (30) is provided in the center of the pintle (29). A cover (4) is a rectangular prism and has front and rear engaging holes (35) which are capable of engaging the engaging posts (17). The guide protruding portions (26) of the pawl body (2) are inserted into the guide grooves (16) of the recess (11) and the pull tab (3) is placed on the supporting pieces (14) from above. Then, the cover (4) is mounted. When the pull tab (3) is raised or hung, the pawl body (2) moves up and down, so that the locking pawls (24) enter in between fastener elements by pressure.
