DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pad used for clothes such as a shoulder pad.

[0002]

2. Description of the Related Art Conventionally, in a pad used for clothes such as a shoulder pad, a shape memory material such as a shape memory alloy or a shape memory resin has been arranged in the pad to improve the formability of the pad. It has been done. In particular, this kind of pad
Even if the shape changes due to long-term storage or washing of clothes, for example, due to temperature rise due to body temperature when wearing clothes, by increasing the temperature to an appropriate temperature,
When worn, there is an advantage that the shape can be recovered and a good shape can be maintained.

For example, Japanese Utility Model Laid-Open Publication No. 63-11519 discloses a shoulder pad in which a long wire made of a shape memory alloy is inserted into a plurality of layers of a soft pad material such as a fiber material. ing. In this shoulder pad, a thin cylindrical hollow portion is formed near the tip (shoulder tip) of the shoulder pad, and a wire made of a shape memory material alloy is inserted from one open end to the other end of the hollow portion. Through. However, since the shape of the shoulder pad itself is three-dimensionally curved and the wire made of the shape memory material alloy is also curved, it takes a lot of time and effort to insert the shoulder pad. If you do not securely close the open end of the hollow part, the tip of the shape memory alloy wire may protrude from the opening, tearing clothes or, in the worst case, damaging people. is there.

In Japanese Utility Model Application Laid-Open No. 4-37217, a flexible pad material such as a fiber material is folded in two, and a wire or a net made of a shape memory alloy is arranged along the fold. A shoulder pad is disclosed. This pad is made by folding the pad material in half and sandwiching the shape memory material between them, which improves the workability of production.However, since the shape memory material is arranged along the fold line, the shape memory material is The position is limited to the fold, and the degree of freedom of the arrangement position is reduced. More specifically, in this pad, the fold is the tip (shoulder tip) of the pad, but the shape memory material is always located at a position along the shoulder, and is located at a position inside the shoulder by a predetermined length. When arranging a shape memory material, it is extremely difficult to position the shape memory material, and workability is deteriorated. Also, if you do not securely close the open end of the cavity after insertion,
There is a possibility that the tip of the wire made of the shape memory material alloy protrudes from the opening and breaks the clothes or, in the worst case, injures a person.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional pad, and more specifically, when arranging a curved shape memory material on a curved pad, The shape memory material can be positioned accurately and the shape memory material can be arranged, and even when accurate positioning is performed, good productivity can be obtained.In addition, the tip of the shape memory material alloy wire protrudes from the opening. It is intended to provide a pad which can prevent clothes from being broken or, in the worst case, from being hurt.

[0006]

A first aspect of the present invention is directed to a flexible pad material 11, 12, 13, 14, such as a fiber material.
The above problem is solved by providing a pad having the following means, in which a shape memory material 3 is arranged inside 15. In the pad according to the present invention, the bag-like body 2 in which the shape memory material 3 is housed is arranged together with the other pad materials 11, 12, 13, 14, and 15. The bag 2 is composed of at least two sheets 21 and 22 located above and below the shape memory material 3. The bag-like body 2 has an opening 4 that opens along the longitudinal direction of the elongated shape memory material 3 between the two sheet-like bodies 21 and 22, and a depth of the opening 4. And a protrusion preventing portion 6, 6 formed by closing a portion of the elongated shape memory material 3 on the extension of the longitudinal end of the elongated shape memory material 3 in the bag-shaped body 2. The positioning part 5 is formed so as to extend along the longitudinal direction of the long shape memory material 3 by connecting the two sheet-like bodies 21 and 22 to each other. The protrusion preventing portions 6, 6 are formed by connecting the sheet members 21 and 22 in a state where at least one of the two sheet members 21 and 22 is folded and overlapped with the other. is there. The opening 4 is opened at the end face of the pad. The opening 4 is opened, and the long shape memory material 3 is inserted into the bag-like body 2, along the positioning section 5, The pad is fixed in the pad by a fixing means such as sewing. A second invention of the present application is the pad according to the first invention, characterized in that synthetic resin caps 31, 31 are attached to both front and rear ends of the long shape memory material 3, respectively. provide.

[0007] At least two sheets 21 and 22 constituting the bag 2 may be formed by folding one sheet into two. The opening 4 is
The opening 4 may be closed when the pad is completed. However, since the opening 4 is not located on the extension of both ends of the long shape memory material 3, even if the opening is not strictly closed as in the conventional case, safety can be maintained. Can be secured.

In the present invention, since the shape memory material 3 is placed in the bag 2 in the pad,
Workability is good, positioning is easy and reliable. That is, by correctly arranging the bag-shaped body 2 at a predetermined position on the pad, the shape memory material 3 can also be correctly positioned at a predetermined position on the pad. In particular, when the shape memory material 3 is made of a long material such as a wire, it is difficult to position the shape memory material 3 by itself. However, by storing the shape memory material 3 in the bag 2, the positioning can be made simple and accurate. it can. Further, in the present invention, since the opening 4 is provided in the bag 2, the shape memory 3 is inserted into the bag 2 by inserting the elongated shape memory 3 through the opening 4. Can be coordinated with In particular, since the opening 4 is formed along the longitudinal direction of the long shape memory material 3, the opening 4 can be greatly opened even with the curved long shape memory material 3,
It can be smoothly inserted into the opening 4. At this time, if the length of the opening 4 is substantially equal to or longer than the length of the long shape memory material 3, the opening can be smoothly inserted without difficulty. Note that the length of the opening 4 is shorter than the length of the long shape memory material 3 as long as the shape memory material 3 can be inserted by bending or distorting the shape memory material 3 or making it oblique. There is no problem in implementation. By inserting the shape memory material 3 into the positioning part 5 formed in the back of the opening 4 at the time of insertion, the shape memory material 3 naturally follows the positioning part 5, and The positioning is completed only by the operation of pushing the.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a pad according to an embodiment, and FIG. 2 is a perspective view of the pad with an opening thereof being opened. FIG. 3A is a plan view of the same pad, and FIG. 3B is a front view of the same pad. FIG. 4 is a perspective view of a bag-like body of the pad, and FIG. 5 is an explanatory view showing a use position of the pad.

As shown in FIG. 5, the pad 1 is a shoulder pad for various kinds of clothes such as heavy clothes such as blazer and school uniforms and light clothes such as one-piece and blouse. Sewn into the upper part of the shoulder k. The shoulder pad 1 is curved so as to extend around the upper part of the shoulder of the garment and extend back and forth (front body side and back body side) of the shoulder. Further, similarly to a normal shoulder pad, the thickness on the side of the shoulder tip k1 (boundary between the shoulder and the arm) is large, and the thickness becomes thinner toward the neck side. In the shoulder pad 1, a shape memory material 3 extending across the front and back of the shoulder is arranged inside the shoulder.

As shown in FIGS. 1 to 3, the shoulder pad 1 is made of a soft pad material 11, 12, 1 made of a fiber material or the like.
The shape memory material 3 is arranged inside a plurality of layers of 3, 14, and 15 stacked. As the pad material, a nonwoven fabric, a woven fabric, a knitted fabric, cotton, a flexible synthetic resin such as urethane, or the like can be used as in the conventional case. In this embodiment, the pad material 11, 12, 13, 14, 15 is formed as a pad by laminating a plurality of layers. However, the number of layers to be laminated can be changed as appropriate, and only one sponge-like pad material is used. , A shape memory material 3 may be arranged therein. In the figure, the pad material 11 on the surface is indicated by a thin line without using a relatively thin nonwoven fabric or woven fabric.

Next, the shape memory material 3 is made of a shape memory alloy or a shape memory resin.
It may be implemented as one or a plurality of wires, or a net, a knitted fabric or a woven fabric, and may be a planar shape memory material having the same area as other pad materials. As the shape memory material, a material that recovers the stored shape at a temperature that is at most the same as the body temperature is suitable, and a material that exhibits a predetermined shape when worn or dried after washing may be used. In this embodiment, a single wire made of a shape memory alloy is used, and by changing this shape, the shape of the entire pad can be adjusted to a desired shape.

The shape memory material 3 is provided with a shoulder k of the shoulder pad 1.
1 is inserted into the shoulder pad 1 through an opening 4 provided in the end face of the shoulder pad 1. That is, the opening 4 is formed so as to extend back and forth along the shoulder along the edge of the pad on the side of the shoulder tip k1. A positioning portion 5 for defining the position of the shape memory material 3 is formed at the back of the opening 4 (that is, at an appropriate position from the tip of the shoulder pad 1 toward the neck). The positioning portion 5 is provided with two sheet-like members 21.2 forming the opening 4.
2 formed by closing. In addition, since these sheet-shaped bodies 21 and 22 are also thin, they are represented by “lines” in the figure. The closing method can be formed by fixing the two sheet-shaped bodies 21 and 22 together by sewing, bonding, metal fittings, or the like. These fixings may be performed linearly continuously,
Several places may be fixed intermittently. In short, shape memory material 3
When the shape memory material 3 is inserted, the shape memory material 3 may be in contact with the shape memory material 3 so that the shape memory material 3 cannot be advanced deeper than the fixed portion.

In this embodiment, the opening 4
Are formed as the bag-shaped body 2,
We are implementing. As the material of the bag-like body 2, the same flexible sheet-like pad material as the other pad materials 11, 12, 13, 14, 15 can be used. More desirably, a smooth and relatively woven cloth (eg, a thick cloth such as canvas or denim) without a pile or the like can be used, but a thin cloth may be used. The structure and the yarn used can be freely changed. Further, the material can be changed to another material such as a synthetic resin sheet or a nonwoven fabric. Further, the bag-like body 2 may be doubled, or three or more stacked.

As shown in FIG. 4, the bag-shaped body 2 has an opening 4 formed by opening one side of a long side facing the opening, and a positioning section 5 by closing the other side of the long side. It has a bag shape at the bottom. Then, two opposed short sides are closed so as to prevent the inserted shape memory material 3 from protruding in the front-rear direction, thereby forming protrusion prevention portions 6 and 6. That is,
When the opening 4 is the mouth of the bag and the positioning part 5 is the bottom of the bag, the protrusion preventing parts 6, 6 correspond to the side of the bag. By closing the side portion of the bag, the bag is used as the protrusion prevention portions 6 and 6.

The shape memory material 3 is inserted through the opening 4. At this time, as shown in FIG. 2, the opening 4 can be greatly opened, and even if the shape memory material 3 is long curved, Naturally, the shape memory material 3 can be inserted from the shoulder k1 to the back through the opening 4 that is widely opened without difficulty. When the shape memory material 3 is inserted until it hits the positioning portion 5 at the back, the position is determined naturally. That is, the shape memory material 3 is in a state along the positioning section 5, that is, in an adjacent state. In particular, as shown in FIG. 3, the shape memory material 3 is curved both when viewed from above and when viewed from the front. Although it was extremely difficult to accurately position the three-dimensionally curved shape memory material 3 and smoothly insert the shape memory material 3 with good workability, the shape memory material 3 was placed on the shoulder tip k1 side over the front and back of the shoulder. The opening 4 that opens over substantially the entire length of the opening 3 can be inserted very easily by widening the opening, and accurate positioning can be achieved only by inserting the shape memory material 3 until it hits the positioning portion 5 at the back. Things.

Further, by providing the protrusion preventing portions 6 and 6 on both sides of the positioning portion 5, the shape memory material 3 can be inserted only until the shape memory material 3 comes into contact with the positioning portion 5 at the back. The position of the shoulder is determined in contact with the prevention portions 6, 6, and the position of the shoulder in the front-rear direction is also determined accurately at the same time. In addition, even if the shape memory material 3 moves back and forth when worn, the front and rear ends of the shape memory material 3 hit the protrusion preventing portions 6 and 6, so that the front and rear ends of the shape memory material 3 are prevented from protruding. It is possible to eliminate the possibility of damaging clothes and people. In this embodiment, the caps 31 made of synthetic resin are attached to the front and rear ends of the shape memory material 3 to increase safety in case of emergency.

Although the inserted shape memory material 3 may be used as it is, as shown in FIG. 1, it may be fixed by sewing using a thread n1 with a sewing machine or the like. Sewing
The bag-shaped body 2 may be sewn on the shoulder k1 side of the shape memory material 3 so that the shape memory material 3 may be fixed between the sewing and the positioning portion 5, or
As shown in FIG. 1, the yarn n1 is
May be sewn and fixed in a zigzag manner. In addition to the sewing, the bag-like body 2 may be formed by other means such as adhesion.
The shape memory material 3 may be fixed by fixing the appropriate positions of the two sheet members 21 and 22. In addition, the fixing by sewing or adhesion may be performed over the whole of the sheet bodies 21 and 22. That is, in a state where the shape memory material 3 is arranged along the positioning portion 5, the two sheet-like members 2 of the bag-like member 2 are formed.
The openings 1 and 22 may be joined to close the opening 4.

The shoulder pad 1 is sewn to the shoulder of the garment like a conventional shoulder pad. At this time, since the position of the shape memory material 3 is accurately determined, the sewing needle is Sewing can be performed without hitting the shape memory material, and needle breakage can be prevented.

Next, a method of manufacturing this pad will be described. First, a continuous pad material 1 that becomes a pair of left and right pads
1a, 12a, 13a, 14a, and 15a and a continuous bag-like body 2a that is a pair of left and right bag-like bodies are prepared. Shoulder pad 1
Are pad materials 11, 12, 13, which have a substantially semi-elliptical shape.
It is formed by laminating a plurality of sheets 14 and 15. Therefore, pad materials 11, 12, 13, 14, 15 constituting each layer
Each time, a semi-elliptical continuous pad material 11a, 12a, 13a, 14 is formed by connecting a semi-elliptical shape to the left and right.
These are prepared for each layer as a and 15a (see FIG. 6). Since a plurality of the continuous pad materials are stacked, the shape, size, thickness, material, and the like are changed according to the layer as in the case of the conventional shoulder pad.

The continuous bag-like body 2a has a substantially elliptical shape in which the above-mentioned substantially semi-elliptical bag-like bodies 2 face each other. More specifically, as shown in FIG.
Are two sheet-shaped members 21 constituting the bag-shaped member 2 described above,
Each of 22 is composed of one continuous sheet-like body 21a, 22a which is connected left and right facing each other. The two continuous sheet bodies 21a and 22a have substantially the same shape, but the other continuous sheet body 22a is formed longer in the front and back than one continuous sheet body 21a.
The front and rear extending portions are turned back portions 6a, 6a. The two continuous sheets 21a, 22a are overlapped with each other, and the folded portions 6a, 6a are folded on the surface of one continuous sheet 21a. By the folded portions 6a, 6a, both ends of the bag are closed, and the protrusion preventing portion 6 of the completed bag 2 is formed. In this figure, one continuous sheet 2
Although the folded portion is provided only in 1a, both of the two sheets may be folded. The positioning portions 5 are formed by sewing both sides of the superposed two continuous sheet bodies 21a and 22a with the thread n2. The folded portions 6a, 6a are formed by the thread n2.
Although it may be sewn on top of "a", it is sufficient to have a sufficient fixing effect even if it is folded. Also, the positioning portion 5 may be formed by providing a folded portion similarly to the protrusion prevention portion 6. Instead of sewing, other fixing means such as adhesion may be adopted.

Next, as shown in FIG. 8A, the continuous pad blanks 11a, 12a, 13a, 14a, 15a and the continuous bag-like body 2a are overlapped with their left and right centers aligned. In this embodiment, 2 is placed on the continuous bag 2a.
The continuous pad materials 11a, 12a come and the continuous pad materials 13a, 14a, 15 beneath the continuous bag 2a.
Although the layers are stacked so that “a” comes, this positional relationship can be appropriately changed depending on the position where the shape memory material 3 is arranged.

Next, the continuous pad material 1
1a, 12a, 13a, 14a, 15a and the continuous bag-like body 2a are bonded and shaped. More specifically, the continuous pad materials 11a, 12a, 13a, 1
An adhesive is applied to at least one of 4a, 15a and the continuous bag-like body 2a (this application is desirably performed before the overlapping). And FIG. 8 (B)
As shown in FIG.
The 2a, 13a, 14a, 15a and the continuous bag-like body 2a (in FIG. 8B, the symbol is represented only by 11a) are placed on the press table p1. From above, steam is jetted while being pressed by the press mold p2. By this heat, the respective materials are formed into a curved shape and are bonded to each other by the adhesive. Note that no adhesive is applied between the continuous sheet bodies 21a and 22a of the continuous bag-shaped body 2a, and the two do not adhere to each other. The continuous pad materials 11a, 12a, 1
The 3a, 14a, 15a and the continuous bag-like body 2a may be provided with a positioning mark on each material in order to accurately align the positional relationship with each other. May not occur.

Next, the continuous pad materials 11a, 12a, 13a, 14a, 15a and the continuous bag-like body 2a, which are superposed and adhered, are cut at the center to form a pair of left and right pad members p.
a, pa (pads of the present application, in which the shape memory material 3 is not yet inserted) are produced. This cut end face
The pad member becomes the shoulder k1, and the end surface of the shoulder k1 is beautifully aligned, and the opening 4 is formed in the bag-shaped body 2 at the end surface of the shoulder k1. Note that the portion x that is cut off and discarded is shaded in FIGS. 8C and 6.

After the pad members pa and pa are formed, as described above, the shape memory material 3 is inserted through the opening 4 and fixed by sewing or the like to complete the shoulder pad containing the shape memory material. . At this time, as shown in FIGS. 3A and 4, locking portions 7 may be provided. The locking portions 7 are formed in front of the positioning portions 5 at both ends of the bag-like body 2, and one end of the shape memory material 3 is connected to the locking portions 7 and the positioning portions 5.
Then, the other end of the shape memory material 3 is inserted between the other locking portion 7 and the positioning portion 5. By performing such an insertion operation, the positions of both ends of the shape memory material 3 are determined more accurately. In addition, when the other end is inserted after the one end of the shape memory material 3 is inserted, it can be prevented that the position of the already inserted one end is shifted.

The locking portion 7 can be formed by sewing the sheet members 21 and 22 together, but can also be formed by fixing the sheet members 21 and 22 by other fixing means such as bonding. Can be formed.

The distance between the locking portions 7 is set shorter than the length of the long shape memory material 3. It is desirable that this length is at least half of the length of the long shape memory material 3 from the viewpoint of operability of insertion. However, even if the length is shorter than that, the shape memory material 3 may be curved. There is no problem in implementation as long as it can be inserted by being distorted or oblique.

The pad of the present invention can be manufactured by another method. For example, the left and right shoulder pads may be separately manufactured. Alternatively, the pad material other than the bag material may be laminated first, and the bag material may be inserted between the pad materials later. Further, in the above-described embodiment, the positioning portion 5 is formed along the outer shape line of the bag-shaped body 2. However, the shape of the positioning portion 5 and the shape of the bag-shaped body 2 do not necessarily have to match each other. It may be extended greatly outside the part 5. More specifically, the positioning portion 5 is formed at an appropriate position by setting the entire size of the bag-like body 2 to the same size as the entire size of the pad (that is, the same size as the pad material 11). May be.

The opening 4 of the bag-like body 2 is provided on the side of the shoulder pad 1 on the shoulder tip side. (Except on the extension). The pad of the present invention is not limited to a shoulder pad, but can be applied to a pad at another location such as a chest.
