Description

Specification

Clothes button

Technical field

The present invention relates to a button for clothes used by being worn on clothes or the like.

Background art

[0002] A clothing button provided with a foot that protrudes in a ring shape downward to the bottom surface of the button body is conventionally used. The clothes button having such a shape is called a shank button or the like, and the legs are integrally formed on the flat button body by drawing a metal plate. .

For example, as shown in FIG. 12 (a), the clothes button 6 is attached to the clothes 7 by entangling the threads 63 at the legs 62 projecting from the bottom of the button body 61. In general, in the case where this yarn 63 is to be entangled, thread the yarn 63 two or three times through the button holes 64 formed in the foot portion 62, and perform root winding (rolling down), and finally perform root tightening. Make a conclusion.

[0004] When manually attaching the button for clothes to the clothes, the buttons and the fabric can be pulled by pulling the force of the worker with force of the worker at the root tightening stage. Sufficient contact force and grounding force S, lower productivity, longer installation time, higher manufacturing cost, and worse yield. For this reason, there was a problem that this manual attachment of the button could only obtain a yield of about 20% substantially compared to the case of machining. In addition, there is a difference in the way of attaching buttons and tightening work among workers, which makes it difficult to control product quality itself uniformly.

For this reason, particularly in recent years, the attachment of the button to clothes has generally been performed using a machine such as a sewing machine. The mechanical method of the button can improve the productivity, shorten the working time, lower the cost, and eliminate the difference in product quality and make it uniform. It also makes it possible to improve yield and yield.

Problem that invention tries to solve

However, when the button is machined, in particular, since there is no step of pulling firmly by the force of the worker at the stage of root tightening, it is possible to fix the foot and the knot of the thread particularly firmly. Absent. For this reason, in the example shown in FIG. 12, even if the clothing button 6 is attached to the clothing 7, the knot of the thread 63 slips on the foot 62, for example, as shown in FIG. As shown in), the button body 61 is inclined obliquely. Because the knot is loose, even if the knot is attached so that the knot is located at the center of the foot 62 at the time of mechanical attachment, this knot gradually increases from the center to the end of the foot 62 by using the button thereafter. In the end, the button body 61 is inclined. Therefore, for example, as shown in FIG. 13 (a), the details of the button 6 in the general view of the garment 7 show the inclined clothing button 6 as shown in FIGS. 13 (b) and (c). , There was a problem that it looks very bad. In particular, when the button body 61 is configured as a so-called decoration button in which a decoration such as a shape or a pattern is attached to the button, the button main body 61 becomes heavy and immediately inclines, so that the expected decoration effect can not be obtained. There was also.

In addition, when the knot 66 of the thread 63 is shifted from the center to the end of the foot 62, the thread 63 is worn away by friction against the foot 62, as shown in FIG. 12 (c). There was also a problem that the yarn 63 was broken and the clothing button 6 could be easily removed from the clothing 7. Furthermore, even if the clothes button is upright after being attached to the clothes, the uprightness may be gradually lost through the subsequent use of the buttons. For this reason, there has been a growing demand for buttoned garments that can maintain their uprightness over a long period of time, particularly in recent years.

Therefore, the present invention has been made in view of the above-mentioned problems, and even when the button for clothes is used for many times, the uprightness of the button for clothes is maintained for a long time. An object of the present invention is to provide a clothes button and clothes that can be held.

Means to solve the problem

[0009] In order to solve the above-mentioned problems, the inventor of the present invention forms a groove in the foot, entangles the yarn in this groove and attaches it to clothes, so that the knot of the yarn jumps out of the groove. Prevention The garment button and the garment have been invented.

That is, the button for clothes to which the present invention is applied comprises a button body and a foot portion that protrudes in a ring shape downward to the bottom surface of the button body, and the foot portion is a string attached to the clothes. A groove for entanglement is formed, and the groove is characterized in that at least the tip is formed with an inclined surface such that the distance between the grooves becomes narrower toward the tip.

Effect of the invention

In the button for clothes to which the present invention is applied, the foot portion projecting in a ring shape downward from the bottom surface of the button body is formed with a groove for entangling a thread attached to the clothes.

[0012] With respect to the button for clothes having such a configuration, by tying the yarn in the groove and attaching it to the clothes, the knot of the yarn does not jump out of the groove, and further, the yarn of the yarn concerned is tied. It is possible to prevent the part from sliding on the foot and slipping to its end. As a result, it becomes possible to prevent the button body of the button for clothes from being inclined, and it becomes possible to fix it in a state of being upright with respect to the fabric of the clothes.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, as a best mode for carrying out the present invention, a button for clothes used by being worn on clothes or the like will be described in detail with reference to the drawings.

FIG. 1 (a) is a rear view of the button 1 for clothes to which the present invention is applied, FIG. 1 (b) is a side view of the button 1 for clothes, and FIG. Fig. 2 shows a perspective view of the clothing button 1;

The clothing button 1 includes a button body 11 and a foot 12 protruding in a ring shape downward with respect to a bottom surface 11 a of the button body 11.

The button body 11 and the foot 12 are integrally formed by drawing a metal plate and / or may be integrally formed of resin with each other. /! In addition to metals and resins, any material may be used.

[0017] The shape of the foot 12 may be any shape as long as it has a ring shape, and may have a polygonal shape consisting of any number of corner portions, or a semi-elliptic or semi-circular shape. It is also good. Also, it may be U-shaped. That is, the foot portion 12 may be formed in any shape as long as a ring for forming a hole for threading a thread is formed. That is, the foot 12 may be formed with a corner that can be bent at approximately 90 °, or may be gradually bent with a curvature without the corner. If it is bent with a curvature, its radius of curvature may be! /, Even a large size! /.

Both end portions of the foot portion 12 are formed so as to enter from the lower side toward the bottom surface 11 a of the button body 11. On the other hand, the central portion 21 of the foot 12 is extended in a substantially horizontal direction. If the shape of the foot 12 is semi-elliptic or semi-circular, the central portion 21 is similarly bent downward to be convex. Further, the foot 12 may be formed in any cross-sectional shape which is not limited to a force which is formed by bending a flat plate into a ring shape.

In addition, a button hole 14 is present inside the foot 12. The shape of the button hole 14 may be any shape, and may be a polygonal shape having any number of corners, or may be a semi-elliptic or semi-circular shape. I'm sorry! The size of the button hole 14 is determined based on the standard for machine attachment such as a sewing machine, and it is desirable that the size is φ 1.5 mm or more. The central portion 21 of the foot 12 is surrounded by a bottom surface 12a, an upper surface 12b, a side surface 12c, and a side surface 12d, as shown in FIG. 1 (a) (b).

In the clothing button 1 to which the present invention is applied, the groove 17 is formed on one or more surfaces of any of the bottom surface 12a, the top surface 12b, the side surface 12c, and the side surface 12d.

In the example of FIG. 1, the grooves 17 are formed on both side surfaces (the side surface 12 c and the side surface 12 d) of the central portion 21 of the foot 12. FIG. 2 is an enlarged view of the groove 17. The grooves 17 are formed with inclined surfaces 31 such that the distance between the grooves 17 narrows at least toward the tip 32. The inclined surface 31 may be a flat surface as shown in FIGS. 2 (a) and 2 (b), but is not limited to this as shown in FIGS. 2 (c) and 2 (d). It may be composed of a curved surface with a slight curvature. Moreover, the tip 32 of the groove 17 may be rounded as shown in FIGS. 2 (a) and 2 (c), or may be sharpened as shown in FIGS. 2 (b) and 2 (d). It is also good.

That is, the shape of the groove 17 is any shape as long as it has an inclined surface 31 indicated by a solid line shown in FIG. It may be composed of

FIG. 3 shows an example in which the groove 17 is formed in a substantially pentagonal cross-sectional shape sharpened in the depth direction. ing. Since the groove 17 having a substantially pentagonal cross section also has the inclined surface 31 in the same manner, the groove 17 is included in the category of the technical idea described above.

By the way, the shape of the groove 17 may be configured to have a substantially n-shaped cross section as long as it has an inclined surface 31 such that the distance between the groove 17 and the tip becomes narrower at least at the tip. 3 or more integer).

FIG. 4 shows the case where the clothes button 1 configured as described above is attached to the clothes 2. When actually attaching the button 1 for clothes to the clothes 2, it is carried out by entangling the yarn 23 in the groove 17. Generally, when this yarn 23 is to be entangled, the yarn 23 is passed through the button hole 14 formed in the foot 12 two or three times or more. At this time, in the clothing button 1 to which the present invention is applied, since the groove 17 is formed in advance in the central portion 21 of the foot portion 12, the yarn 23 is threaded through the button hole 14. It becomes possible to entangle in the groove 17. As a result, after the yarn 23 is wound in the groove 17, root winding (winding down) is performed, and finally root tightening is performed.

The clothing button 1 attached to the clothing 2 in this manner is in a state in which the yarn 23 is wound around the groove 17. In other words, the knotting portion of the yarn 23 is located in the groove 17. For this reason, it is possible to prevent the knot of the yarn 23 from jumping out of the groove 17 and to prevent the knot of the yarn 23 from sliding on the foot 62 and shifting to the end thereof. . As a result, it is possible to prevent the button body 11 of the button 1 for clothes from being inclined, and it is possible to fix the clothes 2 in a state of being upright with respect to the fabric.

[0026] If the clothing button 1 is machined, even if the knot strength of the yarn is loose compared to the case of the manual attachment, the presence of the groove 17 causes the knots of the yarn 23 to be cut. Can be prevented from popping out of the groove 17.

Also, after the clothes button 1 is attached, tensile force and rotational force are applied to the clothes button 1 by using the buttons thereafter. However, even if such a force is applied, in the present invention, the yarn 23 is wound around the groove 17 and wound, and the yarn 23 is prevented from jumping out of the knot of the yarn 23 by fixing it. Can. That is, in the present invention, once attached to the garment 2, it may be inclined even after use. In addition, it becomes possible to always keep the cloth 2 upright.

By configuring all the clothes 2 with the button 1 for clothes to which the present invention is applied, the clothes button 1 in an upright state is not good in appearance even when viewed over the whole clothes 2. It is possible to solve the problem of In particular, by attaching a decoration decorated with a shape or a pattern to the button 1 for clothes, it is possible to prevent the button body 11 from being inclined obliquely even if it is heavy, when it is configured as a so-called decoration button. You can get the effect of decoration you expect.

Further, in the clothing button 1 to which the present invention is applied, since the knot of the thread 23 is not displaced from the center to the end of the foot portion 12, the thread 23 is worn away by friction with the foot portion 12. There is nothing to do. Therefore, it is possible to prevent the yarn 23 from being cut and the clothing button 1 being detached from the clothing 2. Therefore, the present invention can maintain the firmly attached state without being removed from the clothes 2 even for many years of use.

In particular, in the present invention, the groove 17 is required to have an inclined surface 31 which is directed toward at least the tip 32 and the distance between the grooves becomes narrower as the grooves become narrower. When winding the yarn 23 in such a groove 17, the yarn 23 is guided toward the tip of the groove 17 via the inclined surface 31. As a result, the tightening force to the groove 17 by the yarn 23 can be concentrated around the end of the groove 17, and the increase in the slack of the yarn 23 with the use of the button over time results in the lack of curling and uprightness. It becomes possible to prevent. Further, by forming a pointed portion in the groove 17 so as to spread laterally through the inclined surface 31, it is possible to improve the deviation preventing property of the yarn 23 from the groove 17.

In the groove 17, for example, as shown in FIG. 2 (b), the tip of the groove 17 is pointed to the tip through the inclined surface 31 by sharpening the tip. The tightening force of the yarn 23 can be concentrated around the tip, which makes it possible to exert the button uprightness stably for a longer period of time.

Further, the present invention exerts a great effect when the button is attached to the clothes 2 by mechanical attachment. By attaching a button with a mechanical attachment, productivity can be improved, work time can be shortened, and it is possible to reduce the cost and eliminate the difference in product quality and make it uniform. Force, can also improve the yield. In addition to this, in the present invention You can eliminate the inclination of the button, which was a problem when machining, and keep it upright. For this reason, the appearance can be improved by making it stand upright as in the case of hand-making while improving the yield, and a large synergetic effect can be achieved.

Incidentally, in order to keep the button upright, the number of turns of the thread 23 around the groove 17 is determined based on the cross-sectional shape and width of the foot 12, the plate thickness, and the shape and size of the groove 17. It will be Conversely, based on the shape and size force S of this groove 17 and the number of turns of the yarn 23 determined in advance, it is adjusted in advance!

FIGS. 4 (a), (b) and (c) show a button for clothes Γ as another configuration example of the button 1 for clothes. The same components and members as those in the configuration example of FIG. 1 described above are attached with the same reference numerals in the clothing button, and the above description is cited, and the description below will be omitted.

In the button for clothes, the groove 17 is formed on the upper surface 12 b of the central portion 21 of the foot 12. That is, in addition to the side surfaces 12 c and 12 d of the central portion 21, the grooves 17 are further formed on three surfaces of the upper surface 12 b. As a result, when the yarn 23 is entangled, the yarn 23 can be wound in the grooves 17 formed on the three sides, so the yarn 23 is formed on the grooves 17 formed on the two sides like the clothing button 1. As compared with the case of winding, it is possible to fix the knot of the yarn 23 in a more stable state, and it is possible to prevent the jumping out from the groove 17 more firmly. As a result, the clothing button basket can be erected more stably with respect to the clothing 2.

In the present invention, the case where the groove 17 is provided in the central portion 21 of the foot 12 has been described as an example, but the invention is not limited thereto and a protrusion may be provided as an alternative to the groove 17. May be That is, by providing at least two projections in the central portion 21 of the foot portion 12, the yarn can be entangled and wound between the projections, so almost the same effect as in the case where the groove 17 is provided. It can be expected.

As shown in FIGS. 6-9, each shape of the button for clothes is as follows: A— ;! ̃ A—4, B —;! — B—5, C—I;! —C— 3 , D-;! ~ D-4 classified.

In the diagrams shown in FIGS. 6 (a), (b), 7 (a), (b), (c), 8 (a) and 9 (a), A-; — 4 smells The dotted line indicates the site to be defined. Figures 6 (c), 7 (d), 8 (b) and 9 (b) list the shape of each part of the button.

A-2 to A-4 corresponding to FIG. 6 (b) enumerate examples of the groove 17 or protrusion formed on the upper surface 12b. B-1 corresponding to FIG. 7A lists examples of the outer shape of the foot 12. Further, B-2 to B-4 corresponding to FIG. 7 (b) enumerate examples of the groove 17 or the protrusion formed on the bottom surface 12a. B-5 corresponding to FIG. 7 (c) lists the shape of the groove 17 or protrusion formed on the bottom surface 12a or the top surface 12b as viewed from the front.

To D-4 corresponding to FIG. 9 (a) enumerate examples of the groove 17 or protrusion formed on the side surface 12d.

Since the shape of the foot 12 is created by A-1 and B-1, it is essential to select any one of the configurations from A-1 and B-1. In addition to this, in the present invention, A-2 to A-4, B-2 to B-4, C1;! To C-4, D-; The configuration will be selected. In other words, by adopting a configuration one by one from A-2 to A-4, B-2 to B-4, C one;!

Incidentally, A-4, B-4, C-4, and D-4 are examples in which protrusions are provided on both sides of the groove 17. As a result, by tying the knots of the yarn 23 into the grooves 17, slippage of the knots of the yarn 23 can be prevented by the grooves 17 and the projections, and the effect of the present invention can be further improved. It is possible to

Example 1

In order to confirm the above-described effects, the following experimental examination was performed. The garment button 1 to which the present invention is applied was attached to the fabric based on the process described above. As a comparative example, a conventional product having the same button body 11 as the clothing button 1 and having no groove 17 was attached to the fabric by mechanical attachment and manual attachment respectively.

[0043] Next, reverse torsion test and vertical vertical tensile test were performed on each of these buttons. In the reverse torsion test, load 60 gf each on the front and back of the buttoned fabric While pulling the dough, the button was twisted 180 ° at a speed of about 200 times per minute. This reverse screw test was performed 10000 times for one button. In the vertical tension test, while applying a load of 120 gf to the arched foot and pulling it downward, hook the force and the upward hook on the arched foot, and pull it upward until a load of 400 gf is applied. The upper and lower vertical tensile tests were performed 100 times for one button.

As a result, the button 1 for clothing to which the present invention is applied has a stable and upright orientation before and after the test, even after the reverse torsion test and after the vertical vertical tensile test. It has become a state, and the appearance also looks beautiful.

On the other hand, in the comparative example, the orientation of the button was inclined both after machining and after handing, both after passing through the reverse torsion test and after passing through the vertical vertical tensile test.

Example 2

Furthermore, in order to confirm the above-mentioned effects, the following experimental examination was performed. The garment button 1 to which the present invention is applied was attached to the fabric based on the process described above. As a comparative example, a conventional product having the same button body 11 as the clothing button 1 and not provided with the groove 17 was machined and manually attached to the fabric.

Next, these buttons were pressed from the top. As a result, as shown in FIG. 10 (a), the top 1 lb of the button main body 11 was inclined by about 40 ° in the direction of the substantially vertical direction.

Next, the pressure was released with this state set to 0 °. As a result, the force that would cause the button body 11 to return to its original position was measured at this return angle Θ (°). That is, the return angle 基準 is based on the state (0 °) in which the end of the button body 11 is grounded to the fabric. Also, in this measurement, as shown in FIG. 10 (b), the measurement is divided into two patterns, one in the case of pressing in the A direction and the other in the case of the pressing in the B direction. Here, the direction A refers to a direction perpendicular to the longitudinal direction of the foot 12, and the direction B refers to a direction parallel to the longitudinal direction of the foot 12. Measurements were made eight times for each different sample, and the average was taken at the end.

The measurement results of the return angle 結果 are shown in Table 1. [Table 1]

Note 1) The unit is all degrees.

Note 2) All decimal places are rounded up.

Further, the return rates calculated for the return angle and repulsive force in the button main body 11 are shown in Table 2 below. What is the rate of return toward the original position with reference to the end of the button body 11 grounded to the fabric (0 °). It is what displayed as a percentage whether it returns. That is, the return rate is the return angle Θ /

[Table 2]

Note 1) All units are%.

Note 2) All decimal places are rounded up.

From the results of Tables 1 and 2, in the example of the present invention, the return angle ボタン of the button body 11 was larger than that of the comparative example. Similarly, in the inventive example, the return rate was also large compared to the comparative example. That is, in the present invention, since the above-described mechanism works, it can be said that the force S to return to the original position is largely exerted. That is, according to the present invention, even when a pressing force is applied to the button main body 11, it is possible to operate so as to maintain the upright state.

Example 3

FIG. 11 is a configuration example of the back of the foot 12 in the button 1 for clothes to which the present invention is applied. In this example, grooves 17 are formed on both side surfaces (side surface 12 c and side surface 12 d) of the foot 12. In the example of FIG. 11, the groove 17 is formed in a substantially pentagonal cross section. In the example of FIG. 11, 'the width t of the groove 17 is about 0.8 mm, the depth is about 0.7 mm,

1 2

In addition, it is configured to be sharpened over about 0.2 mm in the depth t toward the depth direction. [0055] In the example of FIG. 11, the yarn 23 is first entangled at the tip of the groove 17, and then the yarn 23 is entangled so as to spread on both sides of the tip as the number of turns is increased. As a result, it is possible to concentrate the tightening force to the groove 17 by the yarn 23 centering on the tip, and to prevent the increase of the slack of the yarn 23 with the use of the button with time and the lack of uprightness. It becomes possible. Further, by forming a pointed portion in the groove 17 so as to extend laterally, it is possible to improve the anti-deviation property of the yarn 23 from the groove 17. Further, it is desirable that the angle φ with respect to the horizontal plane in the sharpened surface shown in the drawing in the example of FIG. 11 be 10 to 70 °. The reason is that if the angle φ force S10 ° or less, the tightening force of the groove 17 by the yarn 23 can not be expressed, and the angle φ is 70. If the value of f.sub.2 is exceeded, the pointed portion becomes sharper, and the entwined yarn 23 is worn away. Incidentally, it is desirable that the angle φ be in the range of 30 to 60 ° in order to prevent the breakage of the yarn 23 more firmly and to further improve the concentration of the clamping force.
