Description

[Detailed Description of the Invention] This invention relates to improvement of rain pants.

The raincoat is made of water-resistant fabric made from thermoplastic synthetic resin, and is made by melt-bonding the pieces of fabric using a high-frequency welder to prevent water from penetrating through the seams. However, each part of these rain pants is usually made of one layer, and for example, in the case of fisheries or agricultural jobs where there are many opportunities to work while bending down, only the knee parts wear out quickly.

The purpose of this invention is to eliminate the above-mentioned drawbacks.

That is, this idea overlaps the reinforcing knee pads, which have the same square shape as the knees and are made of the same fabric as the pants body, on the inner surface of the front knee part of the front fabric of the trousers body, uses the edge where the body is to be joined to machine sew the mating margin, and then folds it back. to set the heat,
These rain pants have upper and lower edges welded directly to the front fabric, making them unobtrusive and stylish, as well as improving durability.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. As shown in Figures 1 and 2, the rain pants of this invention are made of waterproof fabric whose front side is waterproofed using thermoplastic synthetic resin such as vinyl chloride, and includes a front fabric 1 and a back fabric. 2 are joined at the side line 3 and inseam line 4 to form a cylindrical leg, and the left and right legs are joined at the front rise line 5 and rear rise line 6 to form the pants body, and an elastic band is attached to the upper edge. Reinforcing knee pads 8 made of the same fabric as the pants body, with 7 sewn on.
are superimposed on the inner surface of the trousers body, and using the armpit joint edge a and the inseam joint edge (not shown), the upper and lower edges are directly bonded to the front fabric, and the periphery is melt-bonded by heat setting using a high-frequency welder. It is what it is.

The waterproof fabric of the rain pants has a thermoplastic synthetic resin waterproof layer on the front side, and the back side remains as a base fabric of, for example, a plain weave structure, and is non-sticky and feels good to the touch when worn.

The front cloth 1 and the back cloth 2 have a side line 3, a crotch line 4, a front crotch line 5, and a rear crotch line 6 connected with a narrow seam allowance 9 instead of a seam allowance.

As shown in FIGS. 2 and 3, the knee pad 8 has the same shape as the knee part of the front cloth 1 (see chain line 8' in FIG. 1).
It is a rectangular cut cloth, and the left and right edges 10 are the front cloth 1, the armpit joint edge a and the inseam joint edge (not shown).
The upper edge 11 and the lower edge 12 are also melt-bonded to the front cloth 1 by heat setting using a high frequency welder.

The joining structure of each cut fabric of the rain pants is the fourth
As shown in the figure and Figure 5A, there is no thermoplastic synthetic resin layer on the back side of the waterproof fabric, so there is no welding performance, and the mating margin 9 of the front fabric 1 and the back fabric 2 is overlapped on the side to be welded. Then, another transparent thermoplastic synthetic resin welding tape 13, for example, is applied, and these are sewn together with a sewing machine 14, and then the seams are folded approximately at the center and melted and bonded by heat setting using a high frequency welder.

In addition, when overlapping the knee pads 8 on the inner surface of the front cloth 1, as shown in FIG.
4, stitch together, fold back and weld.

The rain pants according to this invention have the above-described structure, and are useful for fisheries or agricultural applications where there are many opportunities to work while bending down, for example.
The knee pads have the same shape as the trousers, and use the armpit joint edges and inseam joint edges, so they are unobtrusive and look good, and because they are sewn together using a sewing machine in advance, the joints are very strong and usually harden. Comfortable to wear as the welded edges lie face down.
Even if the knee parts of the trousers are worn out and a hole develops, the knee pads made of the same fabric will be exposed, so it will not be noticeable, water will not get in, and there will be no problem wearing it, and it is more durable than conventional products and can last for a long time. It is economical to use, and since the back side remains as a base fabric, it is non-sticky and feels good to the touch.

Claims (1)

[Scope of utility model registration request] In rain pants, the legs are formed by welding a front fabric and a back fabric made of waterproof fabric having a thermoplastic synthetic resin layer at the armpit joint edges and the inseam joint edge, and on the inside surface of the knee part of the front fabric of the leg. , the reinforcing knee pads are square shaped with the same width as the width of the front fabric, and are made of the same fabric as the trousers body. Weld them directly to the front fabric, and for the armpit joint edges and inseam joint edges, overlap the joining margins of the front fabric, back fabric, and knee pads, overlap the welding tapes, sew them together, and then fold the welding tapes around the core. Rainwear pants characterized by being welded.
