A slider includes a slider body, a tab, and a cover member that is elastically deformable, the slider body has a front attachment post and a rear attachment post standing up from an upper blade, the front attachment post and the rear attachment post have a pair of first side wall portions and a pair of second side wall portions arranged on an outside of the first side wall portions in a length direction, outer wall surfaces of the second side wall portions are arranged on an inside of the first side wall portions via step portions in a width direction, at least a part of the outer wall surfaces of the second side wall portions faces inner wall surface of the cover member. This enables the cover member to be made more difficult to tilt in the width direction even if the cover member receives force.

A ventilation device including a flexible support having first and second edges delimiting a longitudinal opening and being provided with first and second closing devices arranged to cooperate with one another, the ventilation device including at least one elastic spacer member which includes a first tab extending along the first edge and a second tab extending along the second edge, the elastic spacer member being constrained when the closing devices are in the closed position, so that the first and second tabs tend to separate from one another, the length of at least the first tab being less than half the length of the first edge.

In just one separate fastener stringer, a slider stops turning due to collision between a flange of the slider and a fastener element after turning in a direction a connecting pillar of the slider moves away from the fastener element provided in the just one separate fastener stringer. At this time point, an opposed tape side extending toward the flange forms an angle of less than or equal to 45° with respect to a center line of the slider.

A zipper includes zipper teeth, a zipper head base for engaging or disengaging zipper teeth, and a puller with an end hole. The zipper head base includes a body with a pivotal mounting portion, a hook-shaped locking plate with a locking pin, and a biasing member, the hook-shaped locking plate is pivotally connected to the pivotal mounting portion, and the locking pin of the hook-shaped locking plate is configured to pass through the end hole of the puller. The zipper head base has a locked state, in which the biasing member provides a biasing force to the locking plate, so that the locking pin is allowed to be inserted into the engaged zipper teeth to restrict bidirectional movement of the zipper head base. A garment including the zipper is further provided according to the application.

The prevent invention provides a zipper head assembly structure and a sliding assembly thereof. The zipper head assembly structure includes a sliding assembly and a pulling member. The sliding assembly has a base portion, a seat portion, a cover sheet, a spring component, and a retaining member. The cover sheet is disposed on the seat portion. The spring component is disposed inside the seat portion and between the cover sheet and the retaining member. The retaining member is movably disposed on the seat portion and movably contacts the spring component. The pulling member is movably mated with the retaining member. The spring component has a first contacting side contacting the retaining member and a second contacting side, and the cover sheet has a first end portion contacting the second contacting side and a second end portion separated from the retaining member.

There is provided a slider assembly for a slide fastener, including: a slider body; a pull-tab; and a resilient locking member. The pull-tab is provided with a window aligned with an aperture in an upper wing of the slider body when the pull-tab is in a first angular end position. A distal end of the locking member extends towards a guide channel through the window and the aperture. The locking member is configured to be resiliently biased towards a locking position where a distal end thereof protrudes in the guide channel. A proximal end of the pull-tab has a cam cooperating with the locking member such that the locking member takes the locking position when the pull-tab is in the first angular end position, and the locking member is moved towards an unlocking position when the pull-tab is pivoted away from the first angular end position.

There is provided a slide fastener slider. A front mounting portion and a rear mounting portion are respectively provided with receiving grooves for receiving a lock member. The receiving grooves have right and left side walls. Protrusions are respectively provided on upper end edges of the side walls of the front mounting portion. When the upper end portions of the side walls of the front mounting portion are inclined in a direction of approaching each other, the protrusions approach each other, and the protrusions cover the lock member more largely relative to portions of the side walls other than the protrusions.

A cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves corresponding to each other, at least two first retaining blocks corresponding to each other and respectively extended outwardly from the at least two first inner concave grooves, and at least two first through holes corresponding to each other and respectively adjacent to the at least two first retaining blocks. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body to form two breach holes between the inner and the outer surfaces of the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining the elastic piece.

A slider for a slide fastener is disclosed having a slider body and a pull tab wherein: the slider body includes a pull tab retainer having a first side wall and a second side wall with respective recesses for accommodation of the ring of the pull tab, and each recess has a tongue which is inwardly extended to provide a contact surface for the ring, and each tongue joins with the respective side wall with a rounded edge.

A zipper includes zipper teeth, a zipper head base for engaging or disengaging zipper teeth, and a puller with an end hole. The zipper head base includes a body with a pivotal mounting portion, a hook-shaped locking plate with a locking pin, and a biasing member, the hook-shaped locking plate is pivotally connected to the pivotal mounting portion, and the locking pin of the hook-shaped locking plate is configured to pass through the end hole of the puller. The zipper head base has a locked state, in which the biasing member provides a biasing force to the locking plate, so that the locking pin is allowed to be inserted into the engaged zipper teeth to restrict bidirectional movement of the zipper head base. A garment including the zipper is further provided according to the application.
