The present invention relates to the general field of fasteners, and is more specifically concerned with a two-way slide fastener.
Some garment extenders are used, for example, to temporarily extend a garment, such as a jacket or a coat, during pregnancy. These garment extenders are attached between the two halves of an already present garment slide fastener of the garment. These garment extenders also often include their own extender slide fastener that is used to open and close the garment, with the garment extender remaining attached to the garment slide fastener.
Due the morphological changes occurring during pregnancy, such garment extenders typically have a wide portion and a narrow portion. The wide portion is located at the bottom of the garment, to accommodate the expanding belly of the pregnant woman, and the narrow portion is provided at the top of the garment. Once the baby is born, one may wish to extend the garment to accommodate the bulge created by the baby carried in a baby carrier under the garment. Since the baby is usually carried over the chest in such baby carriers, the wide portion and narrow portions would ideally switch position when the garment extender is used to extend the garment to carry the baby.
Switching the narrow and wide portions of the garment extender however results in switching the bottom and top edges of the garment extender. Since conventional slide fasteners can only be joined to each other at a single extremity after having been disengaged, if the extender slide fastener is configured to engage from the bottom during pregnancy, the same slide fastener will be switched upside/down when the garment extender is flipped for baby carrying, which will result in an unnatural top to bottom engagement of the slide fastener.
Accordingly, there exists a need for an improved slide fastener. It is a general objective of the present invention to provide such an improved slide fastener.

Referring for example to
More specifically, the first stringer 12 includes a first tape 20 defining first tape first and second ends 22 and 24, a plurality of first teeth 26 being provided along the first tape 20 between the first tape first and second ends 22 and 24. Similarly, the second stringer 14 includes a second tape 28 defining second tape first and second ends 30 and 32, a plurality of second teeth 34 being provided along the second tape 28 between the second tape first and second ends 30 and 32.
In the embodiment shown in the drawings, the first and second sliders 16 and 18 are mounted permanently to the first stringer 12. To prevent the first and second sliders 16 and 18 from becoming detached from the first stringer 12, the first tape 20 is provided with a retainer pin 36 at each of the first tape first and second ends 22 and 24. The second stringer 14 is provided with a separable pin 38 at each of the second tape second tape first and second ends 30 and 32. The retainer and separable pins 36 and 38 typically have substantially identical lengths, which is typically about the combined length of the channels 40 (seen in
The first and second teeth 26 and 34 and the first and second sliders 16 and 18 may be conventional teeth and sliders used commonly in the art of slide fasteners. Typically, the first and second sliders 16 and 18 are similar to each other. Referring to
The separable pins 38 are similar to conventional separable pins and are made of a substantially rigid elongated piece of material that extends in prolongation of the second teeth 34 and that is small enough to relatively easily enter the channels 40 of the first and second sliders 16 and 18. The separable pins 38 are each reversibly insertable through both channels 40 of the first and second sliders 16 and 18 when the first and second sliders 16 and 18 abut against each other to attach the first and second stringers 12 and 14 to each other or to allow detachment of the first and second stringers 12 and 14 from each other. Typically, the separable pins 38 are substantially elongated and have a constant thickness therealong, thickness referring to measurements in a direction perpendicular to the second tape 32.
The retainer pins 36 each include a retainer pin body 44 similar in shape and dimensions to the separable pin 38, and typically of a constant thickness therealong, but are also provided with a retainer 46 protruding from the retainer pin body 44, for example perpendicularly to the plane in which the channel 40 is formed, which therefore creates a thicker portion in the retainer pin 36 that is thicker than the remainder of the retainer pin 36. The retainer 46 and the channel 40 are configured and sized so that the retainer 46 is unable to travel through the whole channel 40, which prevents the first and second sliders 16 and 18 from detaching from the first stringer 12. In some embodiments, the retainer 46 protrudes from the retainer pin body 44 to an extent preventing the retainer 46 from entering the channel 40, and therefore maintains the first and second sliders 16 and 18 on the first stringer 12. In other embodiments, the retainer 46 may enter the channel 40, but a ledge (not shown in the drawings) protruding inside the channel 40 prevents the retainer 46 from travelling through the whole channel 40. The ledge is also configured and sized to allow movements relative to the first stringer 12 when the retainer 46 is away from the ledge. The retainer pin body 44 and the separable pin 38 are sized to fit both simultaneously and jointly in the channel 40, typically substantially snugly and adjacent to each other at the channel narrow end 43.
When initially detached from each other, the first and second stringers 12 and 14 are attachable to each other by inserting the second stringer 14 in the channels 40 of the first and second sliders 16 and 18 (as seen in
The body 50 is wider at the body first end 56 than at the body second end 58, and therefore tapers in a direction leading from the body first end 56 towards the body second end 56. The body 50 typically tapers uniformly between the body first and second ends 56 and 58, forming a trapezoid. The body 50 defines opposed body first and second surfaces 60 and 62, seen respectively in
