Abstract
Stringers without fastener tape have continuous fastener elements and have element fixing members wherein the fastener elements are sewn together by a sewing thread. The element fixing members are inserted between upper and lower leg sections of the fastener elements. The sewing thread comes in contact with and straddles the upper and lower leg sections of each fastener element and pierces the element fixing members between the fastener elements. As a result of such stringers without fastener tape, the fastener elements can be held and the weight and cost of an article with a slide fastener can be reduced.
Claims8
A stringer comprising:
- a plurality of continuous fastener elements formed from a mono filament, and
- a narrow element fixing member to which the fastener elements are sewn in series by sewing threads,
- wherein each of the fastener elements, formed in a coil shape, has an engaging head which is configured to engage with a facing fastener element in a fastener width direction, upper and lower leg portions extending from the engaging head in the fastener width direction, and a connection portion which extends from the upper leg portion of the continuous fastener element and the lower leg portion of an adjacent fastener element in a fastener length direction and is connected to the lower leg portion of the adjacent fastener element in the fastener length direction,
- wherein the element fixing member is inserted between the upper leg portions and the lower leg portions of the fastener elements along the fastener length direction, and
- wherein the sewing threads come in contact with and bridge over the upper leg portions and the lower leg portions of the respective fastener elements, pierce the element fixing member between the fastener elements adjacent to each other in the fastener length direction and seam the fastener elements and the element fixing member.
An article with a slide fastener comprising:
- a stringer;
- a slider;
- and
- a fastener-attached member having an opening and closing part,
- wherein the stringer includes;
- a plurality of continuous fastener elements formed from a mono filament, and
- a narrow element fixing member to which the fastener elements are sewn in series by sewing threads,
- wherein each of the fastener elements has an engaging head which is configured to engage with a facing fastener element in a fastener width direction, upper and lower leg portions extending from the engaging head in the fastener width direction, and a connection portion which extends from the upper leg portion of the continuous fastener elements and the lower leg portion of an adjacent fastener element in a fastener length direction and is connected to the adjacent fastener element in the fastener length direction,
- wherein the element fixing member is inserted between the upper leg portions and the lower leg portions of the fastener elements along the fastener length direction,
- wherein the sewing threads come in contact with and bridge over the upper leg portions and the lower leg portions of the respective fastener elements, pierce the element fixing member between the fastener elements adjacent to each other in the fastener length direction and seam the fastener elements and the element fixing member,
- one of the sewing threads bridging over the upper leg portions and the sewing threads bridging over the lower leg portions comes in contact with the fastener-attached member, and
- the stringer is attached to the opening and closing part of the fastener-attached member and the slider is slidably attached to an element row formed by the fastener elements.
