Description

Description: TECHNICAL FIELD The present invention relates to a method of manufacturing a shoulder pad for a set-in sleeve, which is built into a shoulder portion of clothes and is integrally formed by thermocompression bonding.

(Prior Art) Conventionally, shoulder pads that are generally sold ignore the shape of the shoulder. In other words, the shape and thickness of the shoulder pad are completely symmetrical between the front side (clavicle side) and the back side (scapula side) about the portion corresponding to the vertical center line. The thickness is just the center,
The shape was such that the central part was thickened, and became thinner regularly before and after (left and right) and toward the base of the neck.

As described above, the conventional shoulder pad floats from the body surface of the shoulder on the front side and the back side of the shoulder. By the way, the shoulder part of the human body is not suitable for the anterior and posterior forms with the line called the acromion line connecting the tip of the shoulder and the center of the cervical root. It has a major drawback in that since it slides down obliquely to the rear side and moves along with the worn clothes, the feeling of wearing is poor, the form of the clothes is difficult to wear, and the appearance is impaired.

And these shoulder pads are mainly manufactured by laying up fabrics, sewing the cotton to be inserted inside,
They were often bonded together, and these were inefficient productions.

(Means for Solving the Problems) The present invention was conceived in order to eliminate the above-mentioned drawbacks of the related art, and was manufactured by adjusting the shape and thickness of the shoulder pad to the shape of the human shoulder. It is made easily and efficiently by using a male and female mold and thermocompression bonding, and cutting the molded product at the center in the horizontal direction into two pieces (a pair). Is what I tried.

For the shoulder, the reference line (referred to as the shoulder line) connecting the base of the neck and the reference point of the shoulder point (referred to as the shoulder point) is very important, and the front part (going toward the chest) Part) and the rear part (part going to the back) are asymmetric. The shape of the front side and the back side are completely different, the area of the front side is small, the area of the back side is large, and the thickness of the front and back is different. The front side becomes thinner as it gets farther from the shoulder,
The rear side has characteristics that match the body shape, with the shoulders being thicker and becoming thinner from here to the back, so by adopting such a shape, the shape conforms to the shape of the shoulders and the seating of the shoulder pads is improved. It does not slide down to the rear.

Further, in the production of the present invention, the fabrics are laminated efficiently by utilizing the characteristics of the thermoplastic synthetic fibers and synthetic resin as the raw materials, and are efficiently produced by thermocompression bonding and molding integrally with a mold. It is easy to make two (one pair) of the same thing by cutting horizontally.

(Structure and Example of the Invention) The structure and example of the present invention will be described with reference to the drawings.

FIG. 1 is a cloth which is placed above and below a shoulder pad for a set-in sleeve manufactured by the present invention, and FIG. 2 is a stack of three small cloths to be inserted into the upper and lower cloths shown in FIG. What
FIG. 3 shows a cloth inserted into the upper and lower cloths, and FIG. 4 shows a male cloth shown in FIG. 2 and FIG. 3 superposed between the two cloths shown in FIG. FIG. 1 is a cross-sectional view of a vertical reference line when viewed from a direction A shown in FIG. 1 when inserted into a female mold and heated and crimped. FIG. 2 is a cross-sectional view as viewed from the direction B shown in FIG.

The cloth shown in Fig. 1 is a vertical ellipse, the widest part of the center of which is the right side (4) and the left side (5) is approximately 55: 45% length,
(6) is the point of contact at the point of the shoulder. This horizontal line (4),
(5) The upper and lower parts are symmetrical, and two (one pair) shoulder pads are formed by cutting this part. In addition, this contact (6)
Is divided into a right half circle (rear side) (1) and a left half circle (front side) (2) with a vertical reference line (3) passing above and below as a boundary. The circumference on the right side (1) is gentle, and the circumference on the left side (2) is steep. The semicircle on the right side (1) has a large area and the half circle on the left side (2) has a small area.

The vertical reference line (3) is called the shoulder line and is the most important line. The point of contact (6) is said to be the point of the shoulder, 20 mm above and below this
The points (26) and (26) (up and down symmetry about the horizontal line) are also the most important shoulder peak points, which are the reference center points of the shoulder pads. Normal from this shoulder line to the end (7) is 100mm
Rank. In addition, the point about 20 mm ahead of (7) is the root of the neck (the same applies to the symmetrical lower part).

When the shoulder pad rests on the shoulder, each of these areas becomes a stable shoulder pad according to the front and rear body shape and structure. Prepare two such cloths at the top and bottom. The cloths (1) and (2) may be non-woven fabrics, ordinary knitted fabrics or stretch woven fabrics.

Next, the shape of a nonwoven fabric (also referred to as a pile) inserted between the two cloths will be described. FIG. 2 shows a state in which three nonwoven fabrics are sequentially stacked from a small one. The wide part is 85% of the horizontal lines (4) and (5) of the cloth and is 55: 45% on the right side and left side of the contact point (shoulder point) (6).

From the point 1/3 of the length between (6) and (7) of the vertical reference line (3), a straight line (11) is drawn, rising to the right and left, and descending.
The down slope line is connected to the end of the horizontal line (5), and the up slope line is similar to the circumference of (1) from the height of half the length of (6) and (7). And is connected to the vicinity of the end of the horizontal line (4) to form a triangle (8) having a short side with the horizontal line as the base and showing a circular shape. In addition, a triangular cloth (14) with no corners, having the horizontal line as the base and having a completely symmetrical upward and downward gradient straight line (17) below the vertical reference line (3). Produce continuously. Next, a cloth (9), (15) having a shape similar to that of the above cloth and having a size of 85%
Is prepared. (12) and (18) are upper and lower oblique straight lines. In addition, similar continuous cloths (10) and (16) having a shape similar to the above-mentioned cloth and having diagonal straight lines (13) and (19) above and below and having a size of 85% of the above-mentioned cloth are produced. I do.

In the embodiment, three sheets are stacked, but two or four sheets may be used. The number of sheets differs depending on the body shape, the thickness of the cloth, the type of clothes, and the like.

FIG. 3 shows an elongated tape-like cloth (20) slightly shorter than the horizontal lines (4) and (5), and the dotted line in the center is a vertical reference line (3), horizontal lines (4) and (5). , Shoulder tip (6).
This cloth may be one sheet, but may be two sheets. In the case of the second sheet, the cloth becomes finer and varies depending on the type of clothes.

Two cloths (1) and (2) each having the shape shown in FIG. 1 are prepared, and the cloths shown in FIG. ) And (5), and the elongated cloth (20) shown in FIG. 3 is also overlapped with these vertical and horizontal lines and shoulder point (6) aligned. This is inserted in the form shown by the dotted line in FIG.

On the other hand, male and female molds are used to mold the shoulder pads. The space of this mold is made by using sand mold and plaster to create the space of the size, thickness and shape as described above. When the male and female are combined, the space conforms to the body shape described above. It has. Fig. 4 shows the vertical reference line (3) when the stack shown in Fig. 2 and Fig. 3 is superposed between the upper and lower fabrics shown in Fig. 1 and inserted, heated and crimped. When viewed from the direction A in FIG. 1 in the cross section of FIG. 1, FIG. 5 shows the point of shoulder (6), horizontal line (4),
(5) The cross section of the portion is viewed from the direction of FIG. 1B. In the figure, (21) and (22) are cross-sectional views of the male mold and the female mold, and both have a thickness of 10 mm.

In the space of these two dies, (1),
If a non-woven fabric or the like is inserted between the two cloths in (2), these can fit in the space as described above. Then, heat treatment, pressure bonding, and molding are performed for several seconds, and the shoulder pad of the present invention is integrally and instantaneously manufactured. In the present application, this is cut at a horizontal line portion to form a pair of shoulder pads used for both shoulders.

The fabric above and below (outside) the shoulder pad of the present application is a synthetic fiber, and a knitted fabric made of polyester or a stretch fabric is used. Polyester nonwoven fabric is used for the stacking cotton that enters the inside, but polyurethane fiber, foamed polyurethane, and the like are also used. In this case, polyester non-woven fabrics are preferred, and these materials have an adhesive that melts.

In the case of molding a non-woven fabric made of polyester, it is pressed and molded at a wet heat of 120 ° C. for about 4 to 5 seconds, and in the case of polyurethane and foamed polyurethane, a dry heat of 200 ° C. for 30 to 40 seconds. The hatched portion (23) in the drawing is the shoulder pad of the present application.

Although the material shown in FIG. 1 is planar, the shoulder pad of the present application differs from the conventional uniform thickness as seen in the cross-sectional view. The size, the thickness of the male and female molds to be crimped and molded together with the shape of the human shoulder, and the thickness at a delicate position are combined.

In the figure, (26) and (26) are shoulder points, (7) is an end, and a dotted line (4) is a horizontal line, which indicates a portion to be cut here. Also, (3) is the shoulder line, (24) is the back shoulder (rear side), and (25) is the front shoulder (front side).

This, together with the thermoplasticity of synthetic fibers and synthetic resins and the adhesive such as non-woven fabric, makes it possible to manufacture shoulder pads efficiently in a short time.

Since the shoulder pad manufactured by the method of the present invention is in such a form, the front side (2) is centered on the vertical shoulder line (3).
And the rear side (1) are not symmetrical, the front side has a small area,
The rear side has a large area, and the front and rear shapes are completely different. The conventional shoulder pad has the same shape in the front and rear, and the thickness is the same in the front and rear, but the front and rear thicknesses of the present application are different. This is about the shoulder point about 20mm from the point of the shoulder, with the wadding between the upper and lower two cloths bordering on the shoulder line, before and after the lower two cloths. This unique shape as well as the great.

In addition, the thickness is largely different before and after. The front part is generally thinner, and the area where the pile is inserted is the largest (8), but the area at the root of the neck in (2) is 1 In the size of / 4 to 1/5, this overlaps at the tip of the shoulder, and gradually becomes thinner with a gentle gradient gradually and turns forward from the shoulder.

At the back, the thick part from the shoulder is also large, and the largest part of the inserted stack (8) is (1) one-half to one-third the size of the entire area, and this is also a gentle slope in order from the shoulder It becomes thin and turns around the shoulder.

The shape of the shoulder pad manufactured in this way is as described above, and is adapted to the shape of the shoulder of the human body. The shoulder is the thickest, especially the thickness from shoulder point (6) to shoulder point (26) of shoulder line (3) is about 10mm. The rear side is considerably thicker toward the base of the arm, and gradually thinner toward the base of the arm.

(Effect) Since it has such a form, the shoulder pad of the present application is well adapted to the form of a human shoulder, and in particular, the inclination of the rear side (rear surface) is strong. It is thicker and has a larger area to prevent it from sliding down the back diagonally.

On the contrary, the front side (front side) is thinner and matches the shape of the shoulder, so that the pad does not move and the aesthetic appearance is not impaired.

In order to manufacture these materials, these materials can be manufactured in a very short time by means of thermocompression bonding and molding with male and female molds, and cut in two at the center to efficiently use a pair of shoulder pads. This has the effect of being able to be manufactured in an efficient manner.
