The prevent invention provides a zipper head assembly structure and a slidable element thereof. The sliding element has a base portion, two lateral wall portions, and a seat portion. The base portion has a front side and a back side. The two lateral wall portions are respectively upwardly extended from two opposite lateral sides of the base portion, and the two lateral wall portions correspond to each other and are connected to the front side of the base portion. The seat portion is disposed on the base portion and connected to the back side of the base portion. The seat portion has a main body disposed on the base portion and connected to the back side of the base portion, two strip convex ribs respectively disposed on two opposite sides of the main body, and two concave spaces respectively connected to the two strip convex ribs.

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.

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.

The invention involves a securable slider assembly for a zipper. The securable slider assembly is formed in a single die cast operation to include the securable slider and the pull being formed simultaneously. At least one side shifting slide is incorporated into the die, which allows the bridge and pull loop to be formed with their full geometric shape and without the converging flat surfaces required in the prior art. The slide assembly includes a puller that includes geometry to allow two slides to be secured together after the closing operation of the zipper teeth and restricts the ability to separate the pullers for opening of the zipper teeth to provide security to the user.

A zipper locking hasp is described which adapts to most conventional zippers without modification to the zipper or to the movable slider parts of a zipper. The hasp is comprised of a plate component with prongs pivotally joined to a channel component. The plate component is fabricated having narrow prongs designed to fit through the conventional aperture present on most zipper sliders. In normal operation, when a zipper is closed, a pair of sliders is brought together along the zipper chain. When the hasp is open, the prongs formed by the plate are inserted through apertures in adjacent sliders which inhibits movement of each slider relative to one another. When the hasp is closed, holes provided in the plate and channel assembly are aligned. A shackle of a padlock can be inserted through the aligned holes keeping the plate and channel components mated locking the zipper.

“A slide (100) for a zip fastener has a hasp (115) and a pull tab (120). This assembly is being moulded into a single block. The pull tab (120) has an eyelet (121) for connecting to the hasp of the slider. The pull tab (120) has a locking eyelet (122) the opening plane of which is parallel to the opening plane of the connection eyelet (121). The pull tab (120) has 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.”

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.

An anti-pinch zipper includes two zipper tapes and a zipper slider. The inner side of the chain cloth of each zipper tape is folded back to the front to form a chain belt portion and a sliding space. The zipper slider has a top plate that holds the pull tab and is provided with a structure to guide the two rows of teeth of the zipper tapes to be interlocked with each other. The rows of teeth and the chain belt portions are passed through the zipper slider, so that the top plate and the pull tab are located on the front of the zipper, and the two chain cloths cover the back of the zipper slider.
