Description

  The present invention relates to a garment with legs such as trousers, slacks, humpe, under a sponge, and crotch.

  Conventionally, various proposals have been made regarding lower garments for people with bent backs. Patent Document 1 discloses a pair of trousers that correspond to the three-dimensional curvature of the waist by providing a double tack on the lower side of the waist belt position of the back body. This method has the advantage that you can use the standard cutouts as they are, but the two deep tacks are like wide pockets, which are stretched and open, bulky and nice looking is not.

  Patent Document 2 shows trousers in which the knee portion is inflated and the front body rise height is 5 cm to 9 cm lower than the rear body rise height. In Patent Document 3, the difference between the front body's crotch height and the back body's crotch height is made larger than the trousers of Patent Document 2, and the waistline in the front body and the back body is greatly inclined, The trousers with the crotch not cut off are shown. In the examples shown in Patent Document 2 and Patent Document 3, both of the conventional cutting diagrams are used, and only the front and rear crotch dimensions are increased and decreased. The waist rubber was difficult to enter, and the fit around the waist was not satisfactory.

In Patent Document 4, the difference between the front body's crotch height and the back body's crotch height is made larger than that shown in Patent Document 2, and the butt portion of the front body crotch is curved to match the shape of the buttocks. The one sewn up is shown. As in this method, it is very difficult to sew in a curved shape, and special equipment or advanced technology is required. In particular, as in this case, it is industrially impossible to sew with a knitted fabric often used for clothing that requires stretchability.

  Thus, the present invention provides a legged garment that can be mass-produced even within the scope of conventional manufacturing equipment and sewing techniques, and that fits well with the body shape of a person with a bent waist and is excellent in wearing feeling. It is for the purpose. In particular, an object of the present invention is to provide a legged garment that provides a wearing feeling equivalent to that of a standard-type person in the front portion of the waist that has not been solved in the prior art.

  The present invention relates to a legged garment in which a crotch line and a side line of a pair of left and right front bodies and a pair of left and right rear bodies are sewn, wherein the left and right front bodies each have a straight waistline and the waistline. When the long side of the rectangle a is the long side of the rectangle a, the short side of the rectangular length s is cut so that it exists in the crotch line and the side line, and the left and right back bodies are respectively straight waist lines. And when the waist line is the long side of the rectangle a ′, the short side of the rectangle s is cut so as to exist in the crotch line and the side line, and the left and right front bodies and left and right Rising leg axis of each side line of the back body and the same angle of inclination in the range of 5 ° to 60 °, respectively, the line extending the short side of the length s of the side lines of the left and right front bodies and the left and right back bodies It is characterized by crossing at θ1.

The product of the present invention is configured as described above, and the waistline of the front body and the back body has the same slope, and the body portion has a cylindrical shape connected by a single straight line. As a result, it is possible to eliminate the unnatural pulling feeling that the center of the back of the lower garment floats and the feeling of pressure on the abdomen when worn in a forward-bending (inclined) state. In addition, the lower garment is shaped like a cylinder with a single straight line from the waistline, so the torso of each front and rear body is sewn by cutting the waistline straight into a rectangular long side. What is necessary is that special equipment and advanced sewing techniques are not required when sewing the waistline in a curved shape in the conventional product. Therefore, a garment that can be cut into a simple shape and easily sewn by anyone is suitable for ready-made garments and is suitable for mass production.
In addition, the length s below the waist line in each front and rear body is a belt band, and the short sides of the four rectangles a, a, a ′, and a ′ are connected to each other. Since the loop is a single straight band, it can be folded in half and sewn, making it easy to manufacture a belt band with rubber bands and rubber bands inside, enabling mass production. Become.

Embodiments shown in the drawings will be described below.
FIG. 1 is a perspective view of a product of a leg garment 1 according to the present invention, and FIG. 2 is a side view of FIG. 1. As is apparent from these drawings, the product of the present invention has a cylindrical shape from the crotch toward the waist. The shape of the torso is sewn so as to be inclined so as to correspond to the forward bending posture in a certain angle range to the front side.

  In each figure, 2 is a pair of left and right front bodies, and 3 is the back body. 4 is a crotch, 5 is a waist, 6 is a waistline from the crotch 4 to the waist 5, 7 is a leg axis rising from the center of the leg, 8 is a center axis of the waist, and 9 is a waist line at the upper edge of the waist It is.

  In the present invention, the waistline portion 6 of the product to be sewn is such that the waistline center axis 8 is inclined to the front side at an inclination angle θ1 of about 5 ° to 60 ° with respect to the leg axis 7 rising from the center of the leg. Accordingly, the angle θ2 at which the plane including the waist line 9 intersects the rising leg axis 7 from the center of the leg forms a descending slope of 90 ° or less.

  3 and 4 show an example of cutting a pattern to be sewn as described above. 2 'is for the front body and 3' is for the back body. As is apparent from these patterns 2 ′ and 3 ′, the present invention product has a unique shape including the waist line x (two-dot chain line) in the shape from the crotch to the waist. In the figure, the alternate long and short dash line indicates the molding of a general product. Hereinafter, this mold making example will be described.

  With respect to the pattern 2 'of the front body, the waist line 9 of the present invention has a constant downward inclination angle θ3 with respect to the horizontal waist line x in general, and this has a certain dimension from the waist line x. A line x 'parallel to this is drawn to the descending part of s, and a virtual rectangular body a formed by these lines x, x', crotch line m, and side line n is directed forward (to the crotch) The rotation is made 10 (counterclockwise).

The dimension s in the above is determined to an appropriate dimension value according to the physique and the degree of bending of the waist. At this time, in the case of L-size slacks for women based on various experiments by the present inventor, it is preferable to set the thickness to 60 mm in accordance with the most demanding body shape.
By the way, the dimension s is designed in the range of 40 mm to 150 mm, and the virtual rectangular body a is formed on the waist part below the waist line as shown in the above example. Even in this case, the waistline central axis 8 intersects the leg centerline 7 at an inclination angle θ1 of 5 ° to 60 °. Although the said inclination | tilt angle (theta) 1 is selected from the many experiment result of this invention, the suitable range of general demand shall be 15 degrees-45 degrees.

  Next, with respect to the back pattern 3 ′, as shown in the drawing, the virtual rectangle a ′ in the above-mentioned pattern of the front body is rotated 11 (counterclockwise) so as to be shifted upward with respect to the horizontal waist line x. The waist line 9 ′ has an inclination angle θ 3 that is about the same as that of the front body. By the way, the crotch line m of the front body is relatively short compared to the general one, and the crotch line m ′ of the back body is relatively long compared to the general one. Specifically, the dimension ratio of the length of the crotch is designed so that the latter is longer by about 25% to 80% than the former. This preferred general demand size is around 60%. Thus, the total length of the side line n of the front body 2 'and the side line n' of the back body 3 'in the above is stitched by making the same dimension. The same applies to the inseam lines v and w.

  Regarding the pattern making of the front body 2 and the back body 3, the waist line 9 of the front body and the waist line 9 'of the back body have the same inclination angle θ3. The inclination angle can be increased (generally such a design). In addition, the virtual rectangular bodies a and a ′ (one-dot chain line segments) assumed on the prototype (general pattern) are rotated counterclockwise at a constant inclination angle θ3 in the illustrated example to perform the desired pattern removal. In addition, it is possible to easily remove the paper pattern by selecting both the upper end of each side line and the intersection point k of the horizontal waist line x in the original pattern with the points moved appropriately (e, e 'in the illustrated example). be able to. In the present invention, such a molding is included in the scope of the present invention.

The product that is cut and sewn in the example of the pattern as shown above is as shown in FIG. 1, and the cylindrical body portion p that is not seen in the conventional product is bent at a certain angle. It will be formed in a (falling down) state.
In this figure, although the opening part at the time of wear is not indicated, it is performed by means such as a fastener at the crotch part or both side line parts. Pockets and the like are also sewn at appropriate places. Although the belt band is sewn separately on the waist line, it may be configured to also serve as the virtual rectangular bodies a and a ′. That is, the virtual rectangular bodies a and a ′ are made into a double fabric, and a rubber string or a rubber band is put inside or sewn.

  The product of the present invention is configured as described above. Instead of reducing the length of the crotch of the front body compared to the general product, the crotch of the back body is made to be a relatively long size, thereby reducing the waist. A body part p having a substantially uniform diameter is formed in the body part below the line. Thus, it eliminates the feeling of pulling at the back, which is a disadvantage of the conventional product, and provides stability to the abdomen and clearance to the back, and is extremely comfortable and comfortable to wear. It becomes a thing.

It is a product perspective view of the lower garment which concerns on this invention. It is a side view of FIG. It is explanatory drawing which shows the cutting example of the pattern for front body. It is explanatory drawing which shows the example of cutting of the back body pattern.
