Description

  The present invention relates to a slide fastener.

  Slide fasteners are attached to used lab coats worn by doctors and nurses and used nursing clothes worn by hospitalized patients so that they can be easily changed. Used clothes are taken home by linens and washed using a large commercial dry washing machine, and then washed white clothes and nursing clothes are returned to the hospital.

  The sliders that engage and disengage the fastener elements (service teeth) attached to a pair of fastener base fabrics sewn on the garment are often damaged or lost during washing. In consideration of this, when the slider is removed from the fastener element and washed in advance, it is necessary to remove the stopper (stopper) attached to the lower end of the fastener element so that the slider does not fall off the fastener element. Therefore, some fastener base fabrics at the lower end attachment position of the fastener element are stitched together with a thread 6 to make a lower end, or there are also inserted a lower end member 10 having a U-shaped cross-section that allows easy removal of the lower end. . However, in this case, both ends of the fastener base fabric that follows the attachment position of the bottom stop protrude randomly on the surface of the garment. There is discomfort because it touches the body.

  In addition, as an invention related to a slide fastener in which a slider is removed and washed, a shape in which two sliders are attached to the fastener body, the sides where the slide grooves close is opposed to each other, and the slide grooves can pass through both ends of the fastener body The stopper composed of the first member and the second member having a shape through which the slide groove cannot pass is arranged so that the left and right combinations of the first member and the second member are opposite to each other at one end and the other end of the fastener body. When the first member of the stopper is pulled out through the slide groove, the first member is detached from the slider and the fastener body is separated, and the slider is slid toward the other end after separation and the two sliders are moved together. There is an invention in which one member is passed and removed from the fastener body (for example, Patent Document 1).

In this case, since the two sliders are bulky, there is an uncomfortable feeling when touching the body, and the number of parts is large, resulting in high production costs. You also have to choose the design, size, thickness, etc. of the slider itself.
Japanese Patent No. 3056219

  If both ends of the fastener base fabric that follows the attachment position of the bottom end protrude randomly on the surface of the garment, the commercial value will decline if the overlaid fabric is not sewn onto the garment itself. It needs to be cleaned up carefully. Further, in the case of the slide fastener according to the above-mentioned Patent Document 1, it is necessary to attach two sliders and a stopper made up of the first member and the second member. There is an uncomfortable feeling when touching, and when replacing the slider, the design, size, thickness, etc. of the slider itself must be selected. An object of the present invention is to solve the above-mentioned problems by simple means.

  In a slide fastener that forms a bottom stop by stitching a thread between the fastener base fabrics facing the lower part of the fastener element, both edges of the fabric band extend between the outer edges of the fastener base fabric following the attachment position for the bottom stop The upper surface of the fastener base fabric and the space are sewn and sewn so that the fastener base fabrics are not separated from each other, and both ends of the fastener base fabric are inserted into the space and covered with a cloth band. The trouble of stitching the protruding fabric to the garment itself was omitted.

  When both ends of the fastener base fabric are inserted into the space formed between the upper surface of the fastener base fabric and the lower surface of the fabric band, the both ends of the fastener base fabric are covered with the fabric band. It doesn't protrude from the fabric band, so it looks good, and both ends don't touch the body, so there is no annoying discomfort. Furthermore, the extra work of sewing both ends to the garment itself is not required. In addition, the garment to which the slide fastener according to the present invention is attached can easily remove the slider from the fastener element by cutting off the bottom end substitute formed by sewing a thread at the time of washing. Can be prevented. Further, the slider can be easily engaged with the fastener element from both ends of the original fastener base fabric and inserted.

  FIG. 3 shows a bottom stop 10 made of a U-shaped member, and the fastener base fabric 4, 4 is not separated from each other by inserting its open leg into the bottom stop position of the bottom portion of the fastener base fabric 4, 4. A conventional example is shown in which when the slider 2 is replaced, the bottom stop 10 can be grasped with fingers and easily pulled out.

FIG. 4 is a partially cutaway front view showing a conventional slide fastener 11, in which a fastener element 13 inserted in a slide groove of a slider 12 and slid is attached to fastener base fabrics 14 and 14, and is fixed to a lower portion of the fastener element 13. 15 and an upper stopper 16 on the top.

  FIG. 1 is a front view showing a state in which the slide fastener according to the present invention is attached to the waist 9a of a gown-type lab coat 9 used by a doctor, and FIG. 2 is an enlarged view of the part A in FIG.

  A slider 2 for engaging and disengaging the fastener elements 3 (service teeth) is slidably inserted into the fastener element 3 and a pair of fastener elements 3 are attached to the upper portions of the fastener elements 3 attached to the pair of fastener base fabrics 4 and 4. The upper stoppers 5 and 5 are attached, and the fastener base cloths 4 and 4 facing each other at the lower part of the fastener element 3 are overlocked with a thread 6 and stitched to form a lower stopper substitute 7 indicated by an arrow so that the slider 2 is moved. In a slide fastener that prevents the slider 2 from being detached from the lower portion of the fastener base fabrics 4 and 4 when pulled down, both ends of the fabric band 8 extend between the outer edges of the fastener base fabrics 4 and 4 following the attachment position of the bottom stop substitute 7. The edge is sewn so that the fastener base fabrics 4 and 4 are not separated from each other, and the lower surface of the fabric band 8 and the fastener base fabric , Was not allowed to protrude from the fabric band 8 together cover the space formed between the upper surface of the 4 end portions 4a of the fastener base fabric 4,4 and 4a in pledge cloth band 8.

  The slide fastener according to the present invention is not limited to the lab coat 9 described above, but is a slide provided on a widely used garment, a laundry net for putting laundry in washing, a cover of a futon or a blanket, etc. Applicable to fasteners.

  Not only has the advantage of being able to quickly wash white lab coats and nursing clothes that are collected in large quantities by linen contractors, and can return them to hospitals in a short period of time. Even for slide fasteners attached to nets, futons, blanket covers, etc., the sliders can be easily exchanged, so the market value is high as a slide fastener with high commercial value.

The principal part notch front view which shows the slide fastener which concerns on this invention. FIG. The front view which shows the bottom stop 10 which consists of the conventional U-shaped member. A partially cutaway front view showing a conventional slide fastener 11.
