Slider Assembly for a Slide Fastener

A slider assembly for a slide fastener, comprising:

• a slider body;
• a pull-tab;
• and a resilient locking member,
• wherein the slider body has upper and lower wings linked by a post and an essentially Y-shaped guide channel defined between the upper wing and the lower wing,
• wherein an upper surface of the upper wing has a recess extending in a longitudinal direction of the slider body,
• wherein the recess has two confronting side walls and a bottom wall disposed between the two confronting side walls,
• wherein the upper wing is provided with an aperture putting the recess in communication with the guide channel,
• wherein the pull-tab has a distal end adapted to be gripped and a proximal end pivotably mounted in the recess of the upper wing, between the two confronting side walls thereof,
• wherein the slider assembly is provided with a pivot pin which extends in a transverse direction of the slider body, through holes in the two confronting side walls and a hole in the proximal end of the pull-tab,
• wherein the pull-tab is provided with a window which is aligned with the aperture in the upper wing when the pull-tab is in a first angular end position relative to the slider body,
• wherein the locking member has a proximal end retained to the slider body, an intermediate portion extending in the recess around the proximal end of the pull-tab, and a distal end extending towards the guide channel through the window in the pull-tab and the aperture in the upper wing,
• wherein the locking member is configured such that the locking member is resiliently biased towards a locking position in which the distal end thereof protrudes to a predetermined extent in the guide channel, and
• wherein the 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.
