Hereinafter, the configuration and examples of the present invention will be described in detail. Conventional bra is provided with a bias tape 20 made in the shape similar to the shape of the chest to support the bottom of the female breast under the cup portion 10, sometimes the wire 30 is inserted as shown in the figure, b It is common to use it. However, the shape of the wire supports the underside of the woman's breast, so that the breast sags downward with gravity and the wire rests on the bias tape 20, or wire 30, for the purpose of bra function or structure. Presses the lower part of the chest. There are many microvascular and lymphatic vessels in the chest, and these vessels and lymphatic vessels may be blocked, which may adversely affect the wearer's health. In the present invention in Figure 1a, the bias tape 20 is distributed at regular intervals to the bias tape 20 of the lower part of the tape that is in close contact with the inner chest of the bra to form a protrusion pressing portion 26 in between. The pressure cancel part 25 is provided in between. That is, the protrusion pressing part 26 protrudes and is in close contact with the chest, and the pressure releasing part 25 which is not protruding from the protrusion pressing part 26 is not in close contact with the chest, or the blood vessels may be in the position due to the lack of adhesion. Do not squeeze the lymph vessels can achieve the purpose. The method of having the protruding pressing portion 26 and the pressure releasing portion 25 in the safety bra of the present invention protrudes in each method described in the present invention directly to the bias tape 20 sewn on the bra when the bra is manufactured. The press part 26 and the press release part 25 are formed, or the press tape 26 and the press release part 25 are provided in the bias tape 20, and the press release part 26 and the press release part are provided. There is a method of making a safety bra by applying the bias tape 20 having the part 25 to the safety bra, and the latter is a more preferable method. Hereinafter, a method of providing the protrusion pressing portion 26 and the pressure releasing portion 25 will be described. A thick cloth is cut out and padded by a stitching means by fixing a thick cloth to the protruding pressing part 26 by a method of providing the protruding pressing part 26 to the bias tape 20 so that the thick cloth becomes the protruding pressing part 26. You can make a configuration. That is, if the thick fabric is cut into small desired sizes and mechanically arranged on one side of the bias tape 20 at regular intervals and fixed by the stitching means, the thick cloth padding becomes the protrusion pressing portion 26, between The bias tape 20 which becomes the pressure relief part 25 can be made. Alternatively, the bias tape 20 may be made of only stitching means without applying a cloth to the bias tape 20, and the needle may be intensively sewed by the sewing means to protrude into the protrusion pressing portion 26. This is similar to the principle of engraving a name by sewing or painting by sewing. Of course, it is a task that can be programmed using a sewing machine means, or a CNC sewing machine means as a mechanical means. In other words, it is possible to make a desired height by laminating a number of threads by sewing on the part to make the protrusion pressing part 26 by sewing and making it to a desired height, and arranging such protrusion pressing parts 26 at regular intervals to bias tape 20 ), A bias tape 20 made of the protruding pressing portion 26 and the pressure releasing portion 25 can be made, and a safety bra can be made. In another method, a thick layer of cotton of the same fabric is placed between two layers of bias tape, and the pressure relief portion 25, which is the periphery of the portion to be made with the protrusion pressing portion 26, is sewn by mechanical sewing and pressed. When fixed, the stitched portion becomes flat and becomes the pressure relief portion 25, and the portion not stitched is provided with abundant cotton to make the bias tape 20 that becomes the protruding pressing portion 26. You can make a used safe bra. Alternatively, button means may be attached to the inside of the bias tape 20 of the bra. It is made by molding a button having a thickness and size according to the purpose, the button is to be spaced at regular intervals and attached to the inside of the bias tape (20). That is, when the button is attached to the protruding pressing portion 26, the button is pressed to the lower side of the chest, the button release portion 25, which is a portion where the button does not run, the pressure is weak or the pressure is weak can achieve the purpose. Apply the cloth to the bias tape in advance to make the protruding pressing portion 26, or to make the protruding pressing portion 26 by the stitching means, or by pressing the button means to make the pressing pressing portion 26. 25), the bias tape 20 alternately provided with the protrusion pressing part 26 can be used in a safe bra, or by using a bias tape not provided with the protrusion part, the bra is made of a braided tape and the protrusion pressing part 26 is applied. To make, or to make the protruding pressing portion 26 by the stitching means, or, by pressing the button means to make the protruding pressing portion 26, the pressure relief portion 25, the protruding pressing portion 26 are alternately provided. The safety bra can be made in a separate working order, which can be a manufacturer's option. However, the correct method is to use the bias tape provided with the pre-press release portion 25 and the projecting compression portion 26 in a safe bra, and it is easy to configure the wire 30 in the center of the bias tape 20. . That is, the wire 30 is provided by using the bias tape provided with the pressure releasing part 25 and the projecting pressing part 26, and placing the wire 30 thereon and covering the flat bias tape again and stitching the edge with sewing means. It is possible to make a safe bra equipped with the pressure relief portion 25, the protrusion pressing portion 26. In the above description, the pressure relief portion 25 and the protrusion compression portion 26 are formed on the bias tape 20 supporting the cup, and the pressure relief portion 25 is provided between the protrusion compression portions 26. It is explained that the blood vessels and the lymphatic vessels that support the chest are not blocked in the relieving part 25. However, in further detail, the bias tape 11, the bias tape 12, the bias tape 13, or the bias tape of the shoulder strap means, etc., which are not shown in the drawing, the pressure canceling section 25 and the projecting pressing section 26 Note that the provided bias tape means can be used. And the important thing is that the compression pressing part 26 is continuously pressed, so when making a safe bra, the pressure relief part 25 and the protrusion pressing part 26 can make a safe bra in the form of staggered, so that the user can use it alternately. have. In other words, if there are two safety bras, the pressure relief portion 25 position of one safety bra is provided with the protrusion compression portion 26 at the same position of the other safety bra, and the user alternates between the two safety bras every day. By wearing it, it is possible to double the purpose of the use of a safe bra by alternating pressure part and pressure relief part every day. The overlap protrusions 21 and the overlap protrusions 22 are seams of the bias tapes, and when the overlapping portions are fixed by sewing means, the protrusions are naturally provided.
