Description

[Detailed description of the invention] The present invention relates to a waterproof structure for the attachment part of a dot button, which consists of a front part with an engaging part and a back part which is integrated with the front part by caulking. Used for the dot button mounting part.

In conventional rainwear, there has been a problem in that rainwater intrudes into the interior through a small gap between the hole in the base fabric and the dot button, which is formed when the dot button is caulked and attached.

The purpose of the present invention is to solve the above problems, and the base fabric 2 on which the plurality of dot buttons 1 are crimped and fixed, and the covering fabric 4 covering the back part 3 of this base fabric 2 are both waterproof and waterproof. The base fabric 2 and the cover fabric 4 are welded together along at least weld lines including the weld lines surrounding these dot buttons, and the dot button mounting portion is constructed of a waterproof structure. It is characterized by comprising the following.

The present invention will be specifically described below based on embodiments shown in the drawings.

In the first embodiment shown in FIGS. 1 to 3, the present invention is applied to the lower front part B of rainwear A, and rainwater is reliably prevented from entering into the lower front part B. This is what I did. The lower front part B has a vertical 1
A plurality of male dot buttons 1, 1, . . . are attached in a row. This dot button 1 has a front part 6 provided with an engaging recess 5.
and a back part 3 which is crimped and integrated therewith, and when the dot button 1 is crimped, the base cloth 2 is sandwiched and fixed between the front part 6 and the back part 3. In this example,
The base fabric 2 includes an outer fabric 7 made of a vinyl sheet,
It is constituted by a webbing cloth 8 made of a vinyl sheet placed on the back side of this outer cloth 7. This two-layer base fabric 2 is formed into a band shape, and a plurality of dot buttons 1, 1, . . . are attached thereto as described above. As shown in FIG. 1, the base fabric 2 is placed on a covering fabric 4 made of a vinyl sheet (in this embodiment, the lower front fabric is used as the covering fabric), and this is welded to the covering fabric 4. They are joined by welding through processing. As shown in FIG. 1, the welding operation is performed on a pair of welding lines a and b along both side edges of the base fabric 2 and on both sides of the dot button 1. This is done along a plurality of welding lines c, c... that connect the welding lines. Therefore, the backs 3, 3, . . . of each dot button 1, 1, . The space surrounded by the covering cloth 4 is sealed.

In the second embodiment shown in FIG. 4, the present invention is applied to the upper front part D of rainwear A, so that rainwater can be reliably prevented from entering into the upper front part D. Yes (see Figure 3). In this embodiment, the upper front part is used as the covering fabric 4, and a plurality of female dot buttons 1, 1, . . . are attached to the strip-shaped base fabric 2 similar to the first embodiment, and Then, cover the base fabric 2 with the covering fabric 4.
It is welded to. Note that 9 is the front part of the dot button 1, which is provided with a recess 10 and a spring part 11 which are removably engaged with the engaging convex part 5. In the other configurations, parts common to the first embodiment are designated by common reference numerals in the drawings.

The third embodiment shown in FIG. 5 is constructed almost the same as the first embodiment, except that the base fabric 2 and the covering fabric 4 are composed of one piece of fabric (such as a vinyl sheet), and the weld line A, b, c', c' are formed along the four circumferential side edges of the base cloth 2, and are characterized in that they are formed so as to surround the plurality of dot buttons 1, 1, . . . as a whole. In this embodiment, a plurality of pieces of webbing 8, 8, . . . are attached only to the necessary locations of each dot button 1, 1, .

In this embodiment, since the base fabric 2 and the covering fabric 4 have a continuous structure, the weld line a along the folded portion is not essential and may be omitted.

The fourth embodiment shown in FIG. 6 is constructed in substantially the same manner as the first embodiment, but the lower front fabric is used as the outer fabric 7 of the base fabric 2, and the covering fabric 4 is a belt-shaped one. It is distinctive in that it uses . In this embodiment, as in the third embodiment, the webbing 8, 8, . . . are attached only to the necessary locations of each dot button 1, 1, .

The present invention can be configured in various ways other than those shown in the above embodiments. In addition to the vinyl sheet, the base fabric 2 and the covering fabric 4 may be made of other waterproof and heat-fusible materials such as a laminate fabric made by laminating a jersey made of nylon thread (or polyester thread) on the back side of a urethane foam film, or a nylon sheet. It can be constructed from materials that have Further, in the above embodiment, the base fabric 2 has a two-layer structure including the outer fabric 7 and the webbing fabric 8, but it may have a single-layer structure. Furthermore, it goes without saying that the attachment parts of the dot buttons 1, 1, . . . are not limited to the upper front part D and the lower front part B of the rainwear.

Since the present invention has the above-mentioned configuration, the hole (the second
Even if rainwater enters the back part 3 of the dot button 1 through a small gap between the dot button 1 and the dot button 1 (shown as P in Figure 4), the back part 3 of the dot button 4 and surrounding weld lines a, b, c, c, a, b,
Since the space is surrounded by c' and c' and sealed by the base fabric 2 and the covering fabric 4, it is necessary to reliably prevent the rainwater from further entering the interior. Further, according to the present invention, the base cloth 2 on which the plurality of dot buttons 1 are attached and the covering cloth 4 covering the base cloth 2 are attached at least along weld lines a, b, and c' including the weld lines surrounding these dot buttons 1. Welded, multiple dot buttons 1
Since we are welding around the mounting part all at once,
Welding work can be performed easily and efficiently.
