DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a threader used for passing a thread through a hole of a needle such as a sewing needle for sewing.

[0002]

2. Description of the Related Art Conventionally, as this kind of threader, for example, there is one shown in FIG. Threader B shown in the figure
Has a wire portion 29 attached to one end of a main body 19 for a user to hold by hand.
Is formed by bending a thin, flexible, stainless steel wire into a hollow shape with a substantially rhombic shape when viewed from the front.

[0005] The threader B having the above structure is, for example, shown in FIG.
As shown in (a) and (b), after inserting the wire portion 29 into the hole 50 of the sewing needle 5, the thread 7 is inserted into the wire portion 29.
And then, as shown in FIG.
9 is used so as to be pulled out from the hole 50 of the sewing needle 5. By using the threader B in this manner, it is possible to eliminate the need to pass the thread 7 directly through the hole 50 of the sewing needle 5,
The threading operation to the sewing needle 5 is simplified.

[0004]

However, the conventional threader B has the following disadvantages.

[0005] First, the wire portion 29 of the threader B is
It is composed of very thin wires. When the wire is thickened, as shown in FIG.
This is because if the thread 7 is passed through the wire portion 29 inserted through the hole 50, it becomes difficult to remove the wire portion 29 from the hole 50 thereafter. For this reason, as the above-mentioned wire, it is common to use a wire having an extremely small diameter of, for example, about 0.1 mm. In particular, the sewing needle for patchwork has a very small thread portion because the threading hole is formed very small. Therefore, in the conventional threader B, the wire rod portion 29 is difficult to see, and the position of the wire rod portion 29 is difficult to recognize not only for a person with weak visual acuity but also for a person with excellent visual acuity. As a result, there is a problem that the work of inserting the wire portion 29 into the hole 50 of the sewing needle 5 cannot be performed so easily. Generally, a glossy silver stainless steel wire is used as the material of the wire portion 29, but such a wire is made of, for example, white cloth or wallpaper having a background when the threader B is used. In this case, it is difficult to distinguish them from these backgrounds, and it is particularly difficult to see them.

Second, when using the above-mentioned threader B, it is customary for the user to hold the threader B with one hand and the sewing needle 5 with the other hand. When inserting both into the hole 50, it is necessary to approach both of them in the air. However, it is difficult to stably bring the two close together in the air, and the positional relationship between the wire portion 29 and the hole 50 of the sewing needle 5 easily shifts due to slight shaking of the user's arm or hand. Therefore, in the related art, there is a case where it is difficult to insert the wire portion 29 of the threader B easily into the hole 50 of the sewing needle 5 due to such a thing.

Third, the conventional threader B has a configuration in which the entire wire portion 29 protrudes from one end of the main body 19. On the other hand, the wire portion 29 is formed of a thin wire, and its strength is very small. For this reason, when handling the threader B or storing the threader B in a sewing box or the like, the wire portion 29 of the threader B tends to come into contact with other articles or the like, and such contact causes the wire rod 29 to be in contact with other articles. The portion 29 is easily deformed and tends to be bent.

The present invention has been made in view of the above circumstances, and has made it easy to insert a wire portion of a threader into a hole of a needle to improve the usability thereof. It is an object of the present invention to prevent the wire portion from being easily damaged.

[0009]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

[0010] That is, the threader provided by the first aspect of the present invention is a threader including a wire portion formed hollow by a wire, and the threader is provided on one side of the wire portion. A background plate portion having a color different from that of the wire portion and having flexibility in a direction facing the wire portion is provided, and a part of the background plate portion is provided in front of the front end portion of the wire portion. It is also located on one side of the area,
And while a gap is formed between the region other than the tip portion of the wire portion and the background plate portion, the part of the background plate portion is more wire-shaped than the other portions of the background plate portion. It is characterized in that it is formed as a convex part protruding so as to approach or contact the part.

[0011] In the threader provided by the first aspect of the present invention, a background plate portion having a color different from that of the wire portion is provided on one side of the wire portion, so that the threader is used. Sometimes, if the background plate portion is located behind the wire portion, the wire portion can be clearly seen based on the difference in color between the background plate portion and the wire portion. Therefore, the user of the threader can clearly recognize the position of the wire portion, and an effect of simplifying the operation of passing the wire portion through a hole of a needle such as a sewing needle can be obtained.

Further, since the background plate portion is provided on one side of the wire portion, the background plate portion also has a function of protecting the wire portion. Therefore, the effect that the possibility that the wire portion is deformed due to contact with another article such as a sewing tool during use or storage of the threader can be reduced.

[0013] Since the part of the background plate portion is arranged on one side of the front region of the front end portion of the wire portion, a user of the threader holds the wire portion of the threader with both hands of the threader and the needle. When approaching the hole of the needle, the needle is brought into contact with a part of the background plate portion, so that the needle and the threader can be stably positioned. With this configuration, the wire portion can be easily inserted into the hole of the needle so that the positional relationship between the needle and the threader does not easily shift.

Since a gap is formed between the background plate portion and the wire portion, after inserting the wire portion into the hole of the needle, a desired yarn is inserted into the wire portion by using the gap. Can be passed through appropriately. In other words, it is possible to appropriately avoid the difficulty in passing the thread through the wire portion due to the provision of the background plate on one side of the wire portion. On the other hand, a part of the background plate portion disposed on one side of the front region of the front end portion of the wire portion has a convex portion protruding closer to or in contact with the wire portion than other portions of the background plate portion. Therefore, by bringing the needle into contact with the convex portion, the hole of the needle can be easily approached to the tip of the wire portion,
The work of inserting the wire into the hole of the needle is further facilitated.
Since the background plate portion has flexibility in a direction facing the wire portion, when a needle is brought into contact with the convex portion,
By appropriately pressing the background plate portion with the needle, the position of the needle in contact with the convex portion can be adjusted, and the positioning between the hole of the needle and the wire portion becomes easier.

[0015] A threader provided by the second aspect of the present invention is a threader having a wire portion formed in a hollow shape by a wire, and the wire portion is provided on one side of the wire portion. A background plate portion having a color different from the background plate portion is provided, and the background plate portion has a cutout or non-cutout hole facing the hole of the wire portion.

According to the threader provided by the second aspect of the present invention, as described below, the operation of passing a thread through a needle hole using the threader is facilitated. That is,
In the case where the hole portion is not provided in the background plate portion and the background plate portion is arranged on one side of the wire portion so as to face the entire region of the wire portion, the wire portion is When passing the yarn, it is necessary to pass the yarn through a gap formed between the wire portion and the background plate portion. On the other hand, if a hole is provided at a predetermined position of the background plate portion, the thread passed through the wire portion (strictly, the hole portion of the wire portion) is directly inserted into the hole provided in the background plate portion. You just need to pass it. Therefore, the operation of passing the thread through the wire portion is further facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a front view showing an example of a threader A according to the present invention. FIG. 2 is a side view of the threader A shown in FIG. FIG. 3 is an exploded sectional view of the threader A shown in FIG.

The threader A includes a main body 1, a wire 2, a background plate 3, and other members to be described later.

The main body 1 is formed in a shape and size convenient for the user to hold with a fingertip, and includes a first synthetic resin member 1a and a second synthetic resin member 1b.
And are joined. The joining of these two synthetic resin members 1a and 1b is performed, for example, by connecting the projection 10 and the hole 1 to each other.
1 and are bonded to each other using an adhesive or the like as necessary. On each surface of the two synthetic resin members 1a and 1b, uneven portions 1 for slip prevention are provided.
3, 13a and the like are provided as appropriate. A metal cutter 6 is sandwiched between the two synthetic resin members 1a and 1b, and a part of the cutting edge of the cutter 6 is formed at the rear part of the two synthetic resin members 1a and 1b (see FIG. 1 to 3 (lower part of FIG. 3). The cutter 6 is used for cutting a thread for sewing.

The wire portion 2 has a diameter of, for example, 0.1 m.
m is formed by bending a stainless steel wire 20 having a hollow shape having a substantially rhombic shape in a plan view.
It is formed in a sharp shape that is easy to insert into the hole of the sewing needle. The base ends 2b, 2b of the wire member 2 are fastened to a suitable plate 21 such as an aluminum plate, for example, and fixed. Thereby, the wire part 2 has a shape retaining property for maintaining a predetermined shape. However, the wire 20
Is flexible, and the wire portion 2 is formed as shown in FIG.
In the direction of arrow N1. The wire part 2
The plate 21 is attached to the main body 1 by, for example, sandwiching the plate 21 between the first synthetic resin member 1a and the second synthetic resin member 1b.

The background plate portion 3 is formed integrally with the first synthetic resin member 1a, is located on one side of the wire portion 2, and extends in the same direction as the longitudinal direction of the wire portion 2. It is provided to extend. 2, the background plate portion 3 is provided so as to form a step H with respect to one side surface 14 of the main body 1. As shown in FIG. The background plate portion 3 has a thin plate portion 30 at its base end side and a thick convex portion 31 at its tip end side,
A gap S is formed between the thin plate portion 30 and the wire portion 2. On the other hand, the convex portion 31 protrudes from the thin plate portion 30 in a direction approaching the wire portion 2, and approaches or contacts the distal end portion 2 a of the wire portion 2. One side surface of the convex portion 31 corresponds to an example of the wall portion 4 according to the present invention, and the wall portion 4 is located forward (upward in FIG. 3 not shown in FIG. 1) than the tip 2 a of the wire portion 2. It is provided to extend.

Since the background plate portion 3 includes the thin plate portion 30, it can be bent and deformed in the direction of arrow N2 in FIG. Of the front and back surfaces of the background plate portion 3, the entire surface of the side surface 3a on the side facing the wire portion 2 is, for example, black, and has a color different from that of the silver stainless steel wire 20 having luster. The side surface 3a also includes a wall surface portion 4, and the wall surface portion 4 is also black. As means for making the side surface 3a black, means for applying black paint, means for attaching a black tape piece or the like, means for thermally transferring black material, or synthetic resin material itself constituting the background plate portion 3 can be used. Various means such as blackening means can be adopted. When the side surface 3a is black, preferably, it is matte black.

Next, an example of the use and operation of the threader A having the above configuration will be described.

First, when using the above-mentioned threader A,
For example, as shown in FIG. 4, holding the threader A and the sewing needle 5, and inserting the wire portion 2 of the threader A into the threading hole 50 of the sewing needle 5, The background plate 3 is made visible. Since the wire portion 2 is glossy silver, while the side surface 3a of the background plate portion 3 is black, the difference in color between the two makes the wire portion 2 easier for a threader user to see. . Therefore, even a person with relatively weak visual acuity can clearly recognize the position of the wire portion 2.

On the other hand, when the distal end portion 2a of the wire portion 2 approaches the hole 50 of the sewing needle 5, the head 5a of the sewing needle 5 is brought into contact with the wall surface portion 4, as shown in FIGS. Thus, by bringing the sewing needle 5 and the threader A into contact with each other, the positional relationship between the sewing needle 5 and the threader A can be stabilized, and the sewing needle 5 and the threader A can be placed in the air in an independent manner. It can avoid swaying and swaying. Further, just by bringing the head 5 a of the sewing needle 5 into contact with the wall surface 4, the hole 50 of the sewing needle 5 and the tip 2
In some cases, the positions of a and a do not match. However, in such a case, the background plate portion 3 is
Is pressed in the direction of the arrow N3, whereby the background plate 3
May be bent in the same direction to adjust the position of the sewing needle 5. In this manner, if the position of the sewing needle 5 is adjusted,
The hole 50 of the sewing needle 5 and the distal end portion 2a of the wire portion 2 can be easily aligned.

As shown in FIG. 6, the tip 2a of the wire 2
When the sewing needle 5 is pressed by an appropriate force F to move the wall portion 4 in the same direction even when the wall portion 4 and the wall portion 4 are in contact with each other in advance, the same as the case shown in FIG. In addition, the alignment between the hole 50 of the sewing needle 5 and the wire portion 2 can be accurately performed. Therefore, in the normal state of the threader A, the wall portion 4 may be in contact with or not in contact with the distal end portion 2a of the wire portion 2.

After the positioning of the sewing needle 5 and the wire portion 2 has been performed as described above, the head 5a of the sewing needle 5 is kept in contact with the wall portion 4 while the head 5a is positioned relative to the wire portion 2. Approach. Thus, the wire portion 2 can be easily inserted into the hole 50 of the sewing needle 5. Since the wall portion 4 is also black, which is different from the wire portion 2, the distal end portion 2a of the wire portion 2 is easy to see, and the above operation is further facilitated.

As shown in FIG. 7, after the wire portion 2 is inserted through the hole 50 of the sewing needle 5, a desired thread 7 is passed through the wire portion 2. A gap S is provided between the wire portion 2 and the background plate portion 3.
Is formed, the operation of passing the thread 7 through the wire portion 2 can be appropriately performed. On the other hand, the distal end portion 2a of the wire portion 2 and the wall surface portion 4 are close to or in contact with each other, and the space between them is narrow. Therefore, the wire portion 2
In the case where the thread 7 is passed through the thread 7, even if the threader user leaves the threader A or the sewing needle 5 for some reason, it is possible to reduce the risk that the sewing needle 5 may come off the wire portion 2 carelessly. It becomes possible and convenient. After passing the thread 7 through the wire portion 2, similarly to the existing threader, the wire portion 2 is pulled out of the hole 50 of the sewing needle 5, so that the thread 7 can be passed through the hole 50. it can.

In the threader A, a background plate portion 3 is provided on one side of the wire portion 2. In the present embodiment, in particular, in the present embodiment, the width and length of the background plate portion 3 are limited to the width of the wire portion 2. Greater than. Therefore, when the threader A is used or stored, the chance of other sewing tools or the like directly contacting the wire portion 2 can be reduced, and the wire portion 2 can be protected. When using the above-mentioned threader A, for example, as shown in FIG.
While the threader A may be used for threading the sewing needle 5 with the threader A mounted on the table T, a step H is provided between the background plate 3 and one side surface 14 of the main body 1. As a result, the background plate portion 3 can be bent and deformed downward. Accordingly, the operation of aligning the hole 50 of the sewing needle 5 with the wire rod portion 2 can be performed accurately by bringing the sewing needle 5 into contact with the wall surface portion 4 and bending the background plate portion 3 downward. .

FIG. 9 is a front view showing another example of the threader Aa according to the present invention. FIG. 10 is a sectional view taken along line XX of FIG. 9 and the subsequent drawings, the same parts as those in the previous embodiment are denoted by the same reference numerals.

This sleder Aa is an elongated main body 1
A is configured such that two wire portions 2, 2 are provided at both ends in the longitudinal direction of A. Each of these two wire portions 2 and 2 has a different thickness in order to be able to accommodate sewing needles of different sizes. On one side of each of the wire portions 2, 2, there are provided background plates 3A, 3A of a color different from that of the wire portions 2, 2, and caps 8, 8 are attached and detached to these portions. It is configured so that it can be mounted freely. Also, each of the two background plate portions 3A, 3A is provided with a convex portion 31A, 31A,
Wall surfaces 4A, 4A whose surfaces guide the sewing needle
It has been.

Thus, the threader according to the present invention is
Instead of being provided so that one wire portion protrudes from only one end of the main body, a threader having a configuration in which two wire portions are provided at both ends of the main body may be used. In the threader according to the present invention, the specific configuration of the main body supporting the wire portion is not limited, and the specific configuration for supporting the wire portion is not limited. Therefore, it is not necessary to integrally form the background plate with the main body. When forming the main body supporting the wire portion, it goes without saying that the main body may be formed using an aluminum metal plate or the like other than the synthetic resin.

In the above-described embodiment, the color of the background plate is black, but the present invention is not limited to this.
The point is that the color of the wire portion should be different from the color of the wire portion so that the wire portion can be easily recognized visually, and may be a color other than black. It is preferable that the entire surface of the background plate portion has a color different from the color of the wire portion. However, the present invention is not limited to this. For example, a portion having the same color as the wire portion may exist. Absent.

[0039]

FIGS. 11 to 13 are front views showing other examples of the threaders Ab to Ad according to the present invention.

The threader Ab shown in FIG. 11 has the same basic structure as that of the threader A described above, but is different from the threader Ab in that a hole 38 is provided in the background plate 3. The configuration is different from that of the threader A. The hole 38 is a non-notched hole penetrating in the thickness direction of the background plate 3, and is provided so as to face the substantially rhombic hole 25 of the wire 2 formed by the wire 20. ing.

In the threader Ab, when the thread 7 is passed through the wire portion 2 after the wire portion 2 is inserted through the hole 50 of the sewing needle 5, the thread 7 passed through the wire portion 2 is directly used as the background plate. What is necessary is just to let it pass through the hole 38 of the part 3. That is, the thread 7 is inserted into the narrow gap S between the wire 20 and the background plate 3.
There is no need to pass through. Therefore, the operation of passing the thread 7 through the wire portion 2 is further facilitated. Of course, if the thread 7 is passed through the wire portion 2 by a sufficient dimension, then the wire portion 2
When the thread 7 is pulled out from the hole 50 of the sewing needle 5, the thread 7
The threading operation can be accurately performed without being accidentally deviated from the thread. In addition, the above-mentioned threader A
In b, since the hole 38 of the background plate 3 is provided so as not to overlap the wire 20, the entire wire 20 can be clearly seen in comparison with the color of the background plate 3, and There is no problem that the wire 20 becomes difficult to see due to the provision of the portion 38.

However, according to the present invention, when a hole for facilitating the threading operation into the wire rod portion 2 is provided in the background plate portion, the specific configuration is still the above-mentioned threader A.
The configuration is not limited to b. In the present invention, the hole 38A provided in the background plate 3 may be formed to be larger in size than the hole 25 of the wire 2 as in a threader Ac shown in FIG. Even with such a configuration, the threading operation into the wire portion 2 can be facilitated, and the background plate portion 3 is partially overlapped on one side of the wire portion 2. Also, it is possible to make the wire portion 2 easier to see in comparison with the color of the background plate portion 3.

In the present invention, the hole 38B provided in the background plate 3 may be formed as a notch-like hole, for example, like a threader Ad shown in FIG. Even with such a configuration, the above-mentioned threaders Ab, A
An effect similar to that of c can be expected. Thus, in the present invention, the specific shape and size of the hole provided in the background plate are not limited.

In addition, the specific configuration of each part of the threader according to the present invention can be variously changed in design. As the wire constituting the wire portion, a material other than stainless steel can be adopted, and the specific shape of the wire portion may be a hollow shape other than a substantially rhombic shape in a front view. Furthermore, the threader according to the present invention can be used for threading various kinds of needles other than general sewing needles, such as sewing needles, regardless of the specific types of needles to which the threader is applied. Needless to say.
