A zip fastener may include a first slider disposed to slide lengthwise along a pair of stringers, and which includes one of a male part and a complementary female part. The other of the male part and the female part is formed on either a member, which may be a fixture fixed to the stringers, or a second slider. The male coupling part includes a neck adjacent an enlarged head, and the female coupling part includes a transverse slot with broad and narrow sections. In a two-handed operation, the male and female parts are mutually engaged to connect the first slider and the member by relative transverse movement, to pass the male part through a mouth of the transverse slot. When latched is closed in this way, axial separation of the first slider from the member is precluded.

A zipper head assembly structure includes a sliding member and a pull member. The sliding member includes a sliding element, an elastic member, and a locking hook, the sliding element has a base portion, a first lateral wall portion, a second lateral wall portion, and a seat portion, and an inner surface of the seat portion is configured with at least one retaining block. The first lateral wall portion and the second lateral wall portion respectively extend upward from opposite side ends of the base portion, mutually corresponding to each other, and are connected to a front end of the base portion. The seat portion is disposed on the base portion and connected to a rear end of the base portion.

A device releasably attachable to a zippered compartment, so as to secure the compartment against unauthorized access is disclosed. The device includes an anchor for mounting the device to the zippered compartment, and a releasable lock for engaging a slider head of the zippered compartment. The anchor includes a clamp, clip, and contact surface so as to engage a portion of the zipper of the zippered compartment. The releasable lock includes a latch. Method of releasably attaching the device to the zippered compartment is also disclosed.

A garment, preferably a garment for infants, toddlers and children, includes a zipper for securing the wearer within the garment. A locking device is provided for securing the zipper in a closed position when the wearer is received within the garment. The locking device has a retaining element for preventing movement of the zipper slider once it has reached its fully closed position, and a first closure element for enclosing the zipper and the retaining element. The locking device protects the and maintains the zipper in its fully closed position in two separate ways, namely, by retaining element preventing movement of the zipper from its fully closed position, and by the closure element which prevents access to the zipper and the retaining element when the zipper is in its fully closed position. Preferably, the zipper and the locking device are provided at a position on the garment which further prevents access to the zipper and locking device by the wearer.

The present invention discloses a zipper structure, relates to the field of bags, and is composed of at least one group of zipper. The zipper comprises pull pieces and a pull head; one end of the pull pieces is matched with a box lock for locking, characterized in that limiting structures matched with each other are arranged between the pull pieces of the zipper; and the pull pieces are limited through the matching of the limiting structures. In this way, when one end of the pull head of a group of zipper is closed and one end of the pull pieces is matched and locked with the box lock, the pull pieces of the group of zipper are closed with each other. Because the limiting structures matched with each other are also arranged between the pull pieces, a pair of pull pieces that are closed with each other are limited jointly by the box lock and the limiting structures under the limit of the limiting structures. In this way, one end of the pull head cannot be moved, thereby achieving the effect that one end of the pull head cannot be pulled after the zipper is matched and locked with the box lock.

A zipper slider lock is provided. The zipper slider lock includes a first sliding device, a second sliding device, and a lock body. The first sliding device includes a first slider and a first puller, wherein one end of the first puller is connected to the first slider. The second sliding device includes a second slider and a second puller, wherein one end of the second puller is connected to the second slider. The lock body includes a lock hole, wherein the first puller and the second puller can be inserted into the lock body through the lock hole in order to be locked by the lock body.

The invention concerns a slider (100) for a zip fastener comprising a hasp (115) and a pull tab (120), the assembly being moulded into a single block, the pull tab (120) comprising an eyelet (121) for connecting to the hasp of the slider, characterised in that: a. the pull tab (120) comprises a locking eyelet (122) the opening plane of which is parallel to the opening plane of the connection eyelet (121); b. the pull tab (120) comprises a portion (125) for connection between the two eyelets (121, 122), called the pull tab body, the width of the cross-section of the pull tab body in a direction perpendicular to the opening planes of the eyelets is greater than or equal to the height of the cross-section in the plane parallel to the opening planes of said eyelets.

A luggage article, such as luggage case, with zipper pull-tabs laterally engaged along inner sides and separably secured by a magnetic force, without interlocking with each other, to allow enhanced manipulation of the zipper pull-tabs, zipper sliders and optionally improved operation of the lock mechanism.

A zip fastener may include a first slider disposed to slide lengthwise along a pair of stringers, and which includes one of a male part and a complementary female part. The other of the male part and the female part is formed on either a member, which may be a fixture fixed to the stringers, or a second slider. The male coupling part includes a neck adjacent an enlarged head, and the female coupling part includes a transverse slot with broad and narrow sections. In a two-handed operation, the male and female parts are mutually engaged to connect the first slider and the member by relative transverse movement, to pass the male part through a mouth of the transverse slot. When latched is closed in this way, axial separation of the first slider from the member is precluded.

A fastening system for a zipper is disclosed which includes locking or interlocking first and second zipper pull tabs. A first zipper pull tab comprises a first base, a hook extending from the first base, and a moveable gate coupled to the first base. A second zipper pull tab comprises a second base, a cover coupled to the second base, and a post extending between the second base and the cover. For interlocking, the moveable gate and hook are further coupled around the post to provide the interlocking configuration of the first and second zipper pull tabs. The first zipper pull tab may be utilized separately from the second zipper pull tab, such as to lock to a coupling ring or another component of a carrying bag.
