Description

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

  2. Description of the Related Art Conventionally, a button for clothes having a foot portion protruding in a ring shape downward from the bottom surface of the button body has been used. A button for clothes having such a shape is called a shank button or the like, and a foot is integrally formed with a flat button body by drawing a metal plate. .

  For example, as shown in FIG. 12A, the garment button 6 is attached to the garment 7 by entwining a thread 63 at a foot 62 projecting from the bottom surface of the button body 61. In general, when the thread 63 is entangled, the thread 63 is passed through the button hole 64 formed in the foot portion 62 two or three times, the root is wound (unrolled), and finally the root is tightened. Make a knot.

  When this button for clothes is attached to clothes by hand, it can be pulled and pulled firmly by the operator's force at the root tightening stage, so it is convenient that the button and the fabric are firmly grounded. However, the productivity is low, the attachment time is long, the manufacturing cost is increased, and the yield is also deteriorated. For this reason, the manual attachment of the button has a problem that a yield of about 20% can be substantially obtained as compared with the case of mechanical attachment. In addition, there is a problem in that it is difficult to uniformly control the quality of the product because there is a difference in how to attach buttons and rooting work among workers.

  For this reason, particularly in recent years, it has become common to attach this button to clothes using a machine such as a sewing machine. The method of using buttons with a machine can improve productivity, reduce work time, reduce costs, eliminate product quality disparity, and improve yield. It can also be improved.

  However, when a button is mechanically attached, there is no process of pulling firmly with the force of an operator at the stage of root tightening, and therefore the foot and the thread knot cannot be firmly fixed. For this reason, in the example shown in FIG. 12, even if the garment button 6 is attached to the garment 7, the knot of the thread 63 will slip on the foot 62, for example, as shown in FIG. As shown, the button body 61 is inclined obliquely. Since the knot is loose, even if it is attached so that the knot is positioned at the center of the foot 62 when the machine is attached, the knot is gradually shifted from the center of the foot 62 to the end by the subsequent use of the button. As a result, the button main body 61 is inclined obliquely. Therefore, for example, as shown in FIG. 13 (a), the details of the button 6 in the overall view of the garment 7 are such that the inclined garment button 6 becomes noticeable as shown in FIGS. 13 (b) and 13 (c). There was a problem that became very bad. In particular, when the button is configured as a so-called decorative button, in which a decorative object such as a shape or a pattern is attached, the button body 61 becomes heavy and tilts immediately, so that the expected decoration effect cannot be obtained. It was.

Further, when the knot 66 of the thread 63 is shifted from the center of the foot portion 62 to the end portion, the thread 63 is consumed by friction with respect to the foot portion 62, and finally, as shown in FIG. There is also a problem that it becomes easy to remove the button 6 for clothes from the clothes 7 due to cutting.
Furthermore, even if the button for clothes is upright after being attached to the clothes, the uprightness may be gradually lost through the use of the button many times thereafter. For this reason, the demand for clothes with buttons that can maintain uprightness over a long period of time has increased particularly in recent years.

  Therefore, the present invention has been devised in view of the above-described problems, and can maintain the uprightness of the clothing button for a long time even when the clothing button is used many times. It is to provide buttons and clothes.

  In order to solve the above-described problems, the present inventor has a structure in which a groove is formed in the foot, and a thread is entangled with the groove and attached to clothes, thereby preventing the thread knot from jumping out of the groove. Invented a button for clothes and clothes.

  That is, a button for clothes to which the present invention is applied includes a button main body and a foot protruding downward in a ring shape with respect to the bottom surface of the button main body. A groove is formed, and the groove is formed with an inclined surface such that the distance between the grooves becomes narrower toward at least the tip, and the groove is formed in a substantially pentagonal cross section sharpened in the depth direction, An angle ψ with respect to the horizontal plane in the inclined surface is configured to be 10 to 70 °.

  In a button for clothes to which the present invention is applied, a groove for entwining a thread to be attached to clothes is formed in a foot part protruding downward in a ring shape with respect to the bottom surface of the button body.

  By attaching the thread to the groove and attaching it to the garment button having such a configuration, the thread knot does not jump out of the groove, and further, the thread knot is on the foot. Can be prevented from slipping to the end. As a result, the button body of the garment button can be prevented from being inclined obliquely, and can be fixed in an upright state with respect to the cloth of the garment.

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

  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. 1 (c) is the button 1 for clothes. FIG.

  The button for clothes 1 includes a button main body 11 and a foot 12 that protrudes downward in a ring shape with respect to the bottom surface 11 a of the button main body 11.

  The button main body 11 and the foot 12 may be integrally formed by drawing a metal plate, or may be formed integrally with each other. Further, any material other than metal and resin may be used.

  The shape of the foot portion 12 may be any shape as long as it is ring-shaped, may be a polygonal shape including any number of corners, and may be a semi-elliptical or semi-circular shape. Moreover, you may comprise by U shape. That is, the foot 12 may be configured in any shape as long as a ring for forming a hole through which the thread is inserted 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. When bent with a curvature, the radius of curvature may be any size.

  Both end portions of the foot portion 12 are configured 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 a semi-elliptical or semi-circular shape, the central portion 21 is similarly bent so as to protrude downward. Moreover, although the foot part 12 consists of the shape which bent the flat plate in the ring shape, it is not limited to this, You may be comprised by what kind of cross-sectional shape.

  Further, the button hole 14 is present inside the foot 12. The button hole 14 may have any shape, a polygonal shape including any number of corners, or a semi-elliptical or semicircular shape. The size of the button hole 14 is determined based on a standard for machine attachment such as a sewing machine, and is desirably set to φ1.5 mm or more. As shown in FIGS. 1A and 1B, 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.

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

  In the example of FIG. 1, grooves 17 are formed on both side surfaces (side surface 12 c and side surface 12 d) in the central portion 21 of the foot 12. FIG. 2 is an enlarged configuration diagram of the groove 17. In the groove 17, an inclined surface 31 is formed so that the distance between each groove becomes narrower toward at least the tip 32. The inclined surface 31 may be configured as a plane as shown in FIGS. 2 (a) and 2 (b), but is not limited to this, and as shown in FIGS. 2 (c) and 2 (d). Or a curved surface with a slight curvature. Further, the tip 32 of the groove 17 may be rounded as shown in FIGS. 2 (a) and 2 (c), or sharpened as shown in FIGS. 2 (b) and 2 (d). Also good.

That is, the shape of the groove 17 may be any shape as long as it has an inclined surface 31 as shown by a solid line in FIG.
FIG. 3 shows an example in which the groove 17 is formed in a substantially pentagonal cross section sharpened in the depth direction. Since the groove 17 having a substantially pentagonal cross section similarly has the inclined surface 31, it is included in the category of the technical idea described above.
Incidentally, the shape of the groove 17 may be configured to have a substantially n-square cross section as long as it has an inclined surface 31 whose distance from each other becomes narrower toward at least the tip (n is 3 or more). integer).

  FIG. 4 shows a case where the clothes button 1 having the above-described configuration is attached to the clothes 2. When the button 1 for clothes is actually attached to the clothes 2, the thread 17 is entangled in the groove 17. In general, when the thread 23 is entangled, the thread 23 is inserted into the button hole 14 formed in the foot 12 two to three times or more. At this time, in the clothing button 1 to which the present invention is applied, the groove 17 is formed in advance in the central portion 21 of the foot 12, so that the thread 23 is inserted into the button hole 14, whereby the thread 23 is inserted into the groove 17. It becomes possible to get involved in. As a result, after the thread 23 is wound in the groove 17, the root winding (unwinding) is performed, and finally the root tightening is performed.

  The clothing button 1 attached to the clothing 2 in this manner is in a state where the thread 23 is wound around the groove 17. In other words, the knot portion of the thread 23 is in the groove 17. For this reason, it is possible to prevent the knot portion of the thread 23 from jumping out of the groove 17 and further prevent the knot portion of the thread 23 from slipping on the foot portion 62 and shifting to the end portion. . As a result, it is possible to prevent the button body 11 in the garment button 1 from being inclined obliquely, and it is possible to fix the button body 11 in an upright state with respect to the cloth of the garment 2.

  Even if the button 1 for clothing is mechanically attached, even if the knot strength of the thread is loose compared to the case of manual attachment, the knot portion of the thread 23 protrudes from the groove 17 due to the presence of the groove 17. Can be prevented.

  Moreover, after attaching the button 1 for clothes, use of the button after that will apply the tensile force and rotational force with respect to the button 1 for clothes. However, even if such a force is applied, in the present invention, the yarn 23 is wound around the groove 17 and wound, and this is fixed to prevent the knot 23 from jumping out of the groove 17. Can do. In other words, in the present invention, once attached to the garment 2, it is not inclined obliquely by subsequent use, and it is possible to always keep it upright with respect to the cloth of the garment 2.

  By configuring the garment 2 with the garment button 1 to which the present invention is applied, the garment button 1 in an upright state becomes unsightly when viewed from the entire garment 2. It becomes possible to eliminate the point. In particular, it is possible to prevent the button body 11 from being inclined even when the button body 11 becomes heavy by attaching a decorative object decorated with a shape, a pattern, or the like to the button 1 for clothes. Can achieve the expected decoration effect.

  Further, in the clothing button 1 to which the present invention is applied, the knots of the thread 23 do not shift from the center to the end of the foot 12, so that the thread 23 may be consumed by friction with respect to the foot 12. Disappear. For this reason, it is possible to prevent the thread 23 from being cut and the clothes button 1 from being removed from the clothes 2. For this reason, this invention can maintain the state attached firmly, without removing from the clothes 2 even for long-time use.

  In particular, in the present invention, it is a requirement that the groove 17 is formed with an inclined surface 31 such that the distance between the grooves 17 becomes narrower toward the tip 32 at least. When the thread 23 is entangled in such a groove 17, the thread 23 is guided toward the tip of the groove 17 through the inclined surface 31. As a result, the tightening force of the thread 23 on the groove 17 can be concentrated around the tip of the groove 17, and the increase in looseness of the thread 23 and the lack of uprightness associated with the use of the button over time can be prevented. It becomes possible. Further, by forming a sharpened portion in the groove 17 so as to spread laterally through the inclined surface 31, it is possible to improve the prevention of deviation of the yarn 23 from the groove 17.

  In the groove 17, for example, as shown in FIGS. 2 (b) and 2 (d), the tip of the groove 17 is sharpened, whereby the yarn guided to the tip via the inclined surface 31. The tightening force 23 can be concentrated around the tip, and the uprightness of the button can be stably exhibited over a longer period.

  Further, the present invention exerts a great effect when the button is attached to the garment 2 with a machine. By attaching buttons with a machine, productivity can be improved, work time can be shortened, cost can be reduced, and product quality gaps can be eliminated, and yield can be made uniform. Can be improved. In addition, according to the present invention, the inclination of the button, which has been a problem when attaching the machine, can be eliminated and held in an upright state. For this reason, it is possible to improve the yield and improve the appearance by making it stand upright as in the case of manual operation, and a synergistic effect can be obtained.

  Incidentally, in order to hold the button in an upright state, the number of windings 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, the shape and size of the groove 17. Become. Conversely, the shape and size of the groove 17 may be adjusted in advance based on a predetermined number of windings of the yarn 23.

  4 (a), 4 (b), and 4 (c) show a clothing button 1 'as another configuration example of the clothing button 1. FIG. In this clothing button 1 ′, the same elements and members as those in the configuration example of FIG. 1 described above are denoted by the same reference numerals, and the above description is cited, and the description below is omitted.

  In the clothes button 1 ′, a groove 17 is formed on the upper surface 12 b of the central portion 21 of the foot 12. That is, the groove 17 is formed on three surfaces of the upper surface 12b in addition to the both side surfaces 12c and 12d of the central portion 21. As a result, when the yarn 23 is entangled, the yarn 23 can be wound in the groove 17 formed on the three surfaces, so that the yarn 23 is inserted into the groove 17 formed on the two surfaces like the button 1 for clothes. As compared with the case where the thread is wound, the knot portion of the thread 23 can be fixed in a more stable state, and the jumping out of the groove 17 can be prevented more firmly. As a result, the button 1 'for clothes can be made to stand upright with respect to the clothes 2 in a more stable state.

  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. However, the present invention is not limited to this, and a protrusion may be provided as an alternative to the groove 17. . That is, by providing at least two protrusions on the central portion 21 of the foot 12, it becomes possible to wind a thread between the protrusions and wind it. Because it can be expected.

  In addition, each shape of this button for clothes is shown in FIGS. 6-9, A-1 to A-4, B-1 to B-5, C-1 to C-3, D-1 to D. -4.

  6 (a), (b), FIG. 7 (a), (b), (c), FIG. 8 (a), and FIG. The part where it does is shown by the dotted line. FIGS. 6 (c), 7 (d), 8 (b), and 9 (b) list the shapes of each part of the button.

  A-1 corresponding to FIG. 6A lists examples of the shape of the button hole 14. A-2 to A-4 corresponding to FIG. 6B list examples of grooves 17 or protrusions 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. 7B list examples of grooves 17 or protrusions formed on the bottom surface 12a. B-5 corresponding to FIG. 7C lists the shapes of the grooves 17 or protrusions formed on the bottom surface 12a or the top surface 12b as viewed from the front. C-1 to C-4 corresponding to FIG. 8A list examples of grooves 17 or protrusions formed on the side surface 12c. D-1 to D-4 corresponding to FIG. 9A list examples of grooves 17 or protrusions 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, in the present invention, one or more configurations are selected from A-2 to A-4, B-2 to B-4, C-1 to C-4, and D-1 to D-4. Will be. In other words, by adopting the configuration one by one from A-2 to A-4, B-2 to B-4, C-1 to C-4, D-1 to D-4, Any of the grooves 17 or the protrusions may be provided on all of the bottom surface 12a, the top surface 12b, and the side surfaces 12c and 12d.

  Incidentally, A-4, B-4, C-4, and D-4 are examples in which protrusions are provided on both sides of the groove 17. Thus, if the knot portion of the thread 23 is entangled in the groove 17, it is possible to prevent the knot portion of the thread 23 from slipping by the protrusions in addition to the groove 17, and further improve the effect of the present invention. Is possible.

  In order to confirm the above-described effects, an experimental study described below was performed. The button 1 for clothes to which the present invention was applied was attached to the fabric based on the process described above. As a comparative example, a conventional product made of the same button body 11 as the clothing button 1 and not provided with the groove 17 was attached to the fabric by mechanical attachment and manual attachment, respectively.

  Next, an inverted torsion test and an up / down vertical tensile test were performed on each of these buttons. In the reverse torsion test, the button was twisted 180 ° at a speed of about 200 times per minute while applying a load of 60 gf before and after the buttoned fabric and pulling the fabric. This inversion torsion test was performed 10,000 times per button. Further, in the vertical vertical tensile test, a load of 120 gf is applied to the arch-shaped foot portion and pulled downward, and an upward hook is hooked on the arch-shaped foot portion and pulled upward until a load of 400 gf is applied. This vertical vertical tensile test was performed 100 times per button.

  As a result, the button 1 for clothes to which the present invention is applied has a stable and upright state before and after the test even after the reverse torsion test and the vertical vertical tensile test. And it looked beautiful.

  On the other hand, in the comparative example, the direction of the button was tilted both in the machine mounting and in the hand mounting, both after the reverse torsion test and after the vertical vertical tension test.

  Furthermore, in order to confirm the above-described effects, an experimental study described below was performed. The button 1 for clothes to which the present invention was applied was attached to the fabric based on the process described above. As a comparative example, a conventional product made of the same button body 11 as the clothing button 1 and not provided with the groove 17 was attached to the fabric by mechanical attachment and manual attachment, respectively.

  Next, these buttons were pressed from above. As a result, as shown in FIG. 10 (a), the vertex 11b of the button body 11 that was initially oriented in the substantially vertical direction was tilted by about 40 °.

  Next, this state was set to 0 °, and the pressing was released. As a result, the button body 11 is returned to the original position, and the return angle θ (°) at this time was measured. That is, the return angle θ is based on a state (0 °) in which the end of the button body 11 is grounded to the cloth. In this measurement, as shown in FIG. 10B, the measurement is performed in two patterns, that is, when the pressure is applied to be inclined in the A direction and when the pressure is applied to be inclined in the B direction. The A direction herein refers to a direction perpendicular to the longitudinal direction of the foot 12, and the B direction refers to a direction parallel to the longitudinal direction of the foot 12. The measurement was performed 8 times for each different sample, and finally the average was taken.

  Table 1 shows the measurement results of the return angle θ.

  The return rates calculated from the return angle θ in the button body 11 are shown in Table 2 below. The return rate is a percentage indicating how many degrees the button body 11 returns to the original position with reference to the state where the end of the button body 11 is grounded (0 °). That is, the return rate can be expressed as a return angle θ / 40 × 100 (%).

  From the results of Tables 1 and 2, the return angle θ of the button body 11 was larger in the example of the present invention than in the comparative example. Similarly, the inventive example also had a higher return rate than the comparative example. That is, it can be said that the example of the present invention confirms that a large force is applied to return to the original position because the mechanism described above works. That is, according to the present invention, even when a pressing force is applied to the button body 11, it is possible to act so as to maintain an upright state.

FIG. 11 is a configuration example of the back surface of the foot 12 in the clothing button 1 to which the present invention is applied. In this example, grooves 17 are formed on both side surfaces (side surface 12c, side surface 12d) of the foot portion 12, respectively. In the example of FIG. 11, the groove 17 is formed with a substantially pentagonal cross section. In the example of FIG. 11, the width t ₁ of the groove 17 is about 0.8 mm, the depth t ₂ is about 0.7 mm, and is further sharpened by about 0.2 mm per depth t ₃ in the depth direction. It is made into a structured.

In the example of FIG. 11, the yarn 23 is first entangled at the sharpened portion in the groove 17, and then the yarn 23 is entangled so as to spread on both sides of the sharpened portion as the number of turns is increased. As a result, the tightening force of the thread 23 on the groove 17 can be concentrated around the sharp point, and the increase in looseness of the thread 23 and the lack of uprightness associated with the use of the button over time can be prevented. It becomes possible. Moreover, it becomes possible to improve the escape prevention property from the groove | channel 17 of the thread | yarn 23 by making it the structure which formed the sharpened part in the groove | channel 17 and spread laterally.
Further, in the example of FIG. 11, it is desirable that the angle ψ with respect to the horizontal plane in the sharpened surface shown in the drawing is 10 to 70 °. The reason is that if the angle ψ is 10 ° or less, the tightening force of the groove 17 by the thread 23 cannot be expressed, and if the angle ψ exceeds 70 °, the sharpened portion becomes sharper. This is because the entangled yarn 23 is worn out. Incidentally, it is desirable that this angle ψ is further in the range of 30 to 60 ° from the viewpoint of more firmly preventing the thread 23 from being worn out and further improving the concentration of the tightening force.
