Abstract
A separable bottom end stop for a reverse opening-type slide fastener, in which left and right element rows of left and right fastener stringers can be opened from an upper end and a lower end, the slide fastener includes a lower slider for opening the left and right element rows from the lower end, the lower slider includes a locking claw, which is elastically biased to a protruded position protruding into an element guide path of the lower slider, an insert pin connected to the lower end of one of the left and right element rows, and a box pin connected to the lower end of the other of the left and right element rows. At least one of the box pin and the insert pin includes a release groove capable of receiving the locking claw on a side surface opposing to the other side surface.
Claims12
A separable bottom end stop for a reverse opening-type slide fastener (100), in which left and right element rows (12) of left and right fastener stringers (10) can be opened from an upper end and a lower end, the slide fastener (100) comprising:
- a lower slider (30) for opening the left and right element rows (12) from the lower end, the lower slider (30) including a locking claw (40), which is elastically biased to a protruded position protruding into an element guide path (34) of the lower slider (30);
- an insert pin (50) connected to the lower end of one of the left and right element rows (12);
- and
- a box pin (60) connected to the lower end of the other of the left and right element rows (12),
- wherein at least one of the box pin (60) and the insert pin (50) includes a release groove (63) capable of receiving the locking claw (40) on a side surface (62) opposing to the other side surface,
- wherein at least one of the box pin (60) and the insert pin (50) includes a protruded piece (66) protruding from one side surface (62) toward the other side surface (51), the side surfaces (62, 51) being opposing to each other,
- wherein the release groove (63) extends upward at least to a lower end of the protruded piece (66), and
- wherein the release groove (63) includes a guide face (65b) as an inclined groove side face, which extends obliquely upward in a longitudinal direction and toward a front side in a front-and-back direction.
A separable bottom end stop for a reverse opening-type slide fastener (100), in which left and right element rows (12) of left and right fastener stringers (10) can be opened from an upper end and a lower end, the slide fastener (100) comprising:
- a lower slider (30) for opening the left and right element rows (12) from the lower end, the lower slider (30) including a locking claw (40), which is elastically biased to a protruded position protruding into an element guide path (34) of the lower slider (30);
- an insert pin (50) connected to the lower end of one of the left and right element rows (12);
- and
- a box pin (60) connected to the lower end of the other of the left and right element rows (12),
- wherein at least one of the box pin (60) and the insert pin (50) includes a release groove (63) on a side surface (62) opposing to the other side surface, which is capable of partially receiving the locking claw (40) at a time when upper ends of the box pin (60) and the insert pin (50) become housed in the lower slider (30) through a rear opening (34a), when the lower slider (30) is pulled upward from its lower end position to a first element split position at which lower end first elements (12b) are split, and
- wherein the release groove (63) includes a guide face (65b) as an inclined groove side face, which extends obliquely upward in a longitudinal direction and toward a front side in a front-and-back direction.
