<p>. Several embodiments are disclosed of a bottom stop of a slide fastener of the type comprised of three members, two secured to one stringer tape and one to the other, such that once the three members are passed through the Y-shaped channel, they interengage to form a unitary stop member that cannot be disassembled. Contrary to prior art wherein at least one part of the stop member is of a greater maximum width than the maximum width of the respective channel of the slider, to secure abuttive opposition to the movement of the slider, the invention provides elements that can all pass relatively smoothly through the respective slider channels when assembling the stop. The abutting action is achieved by a concave protrusion on one of the members by its engagement with the neck of the slider. The interengagement of the members is such as to prevent separation of the assembled stop both transversely of and perpendicularly to the fastener rows, while facilitating the assembling by avoiding forced passage of at least one stop member through the slider and the resulting damage to at least one of the members to the channel of the slider or to both, frequently encountered in prior art stops of this type.</p> |
