Benefits of technology

[0023]The invention has the advantage that the slider is securely kept in the closing position. It should be noted that the snap-on engagement between the locking elements and the slider, namely the puller thereof, provides a quick and simple locking / unlocking action, so that the slider of the fastener is securely kept in the closing position and prevented from accidental opening even under intensive use, but the user can open the fastener rapidly and easily at any time.
[0024]The invention is particularly useful in a fluid-tight fastener, where a small deviation of the slider from the full-closing position may compromise the fluid-tightness. Hence, an item fitted with a slide fastener according to the invention, such as a sports garment or the like, gives reliable fluid-tight performance with easy and safe use.

Problems solved by technology

In fact, an accidental displacement of the slider, even of few tenths of a millimeter, may compromise the fluid-tightness of the fastener at the region of the top stop and / or between the teeth.

Embodiment Construction

[0032]FIG. 1 shows a top portion of a slide fastener 1, in accordance with a preferred embodiment of the invention, comprising a pair of tapes 2, equipped with teeth 3, a top stop 4, and a slider 5 with a puller 6. The puller 6 is connected to the slider 5 by a ring 7.

[0033]The slider 5 is movable in a sliding direction, parallel to tapes 2, up to a closing position where the slide fastener 1 is fully closed, i.e. all teeth 3 are engaged and the slider 5 is in contact with the top stop 4. Said closing position is shown in FIG. 1.

[0034]Details of tapes 2 an teeth 3 can be according to known art and are not discussed in detail. For example, in a fluid-tight sliding fastener, tapes 2 are made of a textile core layer fully coated on both sides by a suitable waterproof layer and teeth 3 are injection-molded on tapes 2. The top stop 4, in a fluid-tight slide fastener, can also be injection-molded on tapes 2.

[0035]The slider 5 (FIG. 2) substantially comprises upper and lower blades 8, 9 wi...

Abstract

A slide fastener (1) comprising a slider (5) with a pull-tab (6), and a top stop (4) with a retaining element (20) disposed to act against a contact face (30) of the puller (6), when said pull-tab (6) is in a suitable locking position, to prevent the slider (5) from sliding away and keep the fastener (1) closed.

Description

FIELD OF APPLIATION[0001]The present invention refers to a slide fastener and to a top stop of a slide fastener. The invention relates in particular to fluid-tight slide fasteners and top stops of fluid-tight slide fasteners.PRIOR ART[0002]A slide fastener, in essential terms, comprises a pair of tapes bearing respective rows of teeth, top and bottom stops, and a slider for opening and closing the fastener by engaging and disengaging the teeth. The slider is operated by a puller (or pull-tab) which is usually connected to the slider by a ring or a ring shaped end portion of the same puller.[0003]The top and bottom stops are at opposite ends of the slide fastener, which is completely closed when the slider reaches the top stop.[0004]Fluid-tight slide fasteners, in particular, are used in sports and outdoor activity items, diving or sailing suits, camping tents and the like, and are required to securely prevent the passage of a liquid and / or gas, e.g. water and / or air. In some cases, ...
