[Technical field to which the device belongs]

 This invention relates to the shape of a tie bar that stops a tie.

[0002]

[Prior art]

 One of the ornaments that stop the tie is a tie bar. For example, as shown in FIG. 7, a conventional tie bar 1 has a decoration bar 2 to be decorated and a clip bar 3. Both bars 2 and 3 are pin-coupled so that they can be opened and closed, and are urged in the closing direction by a coil spring 5 mounted around a pin-coupled shaft 4. A serrated tooth-like portion 6 for increasing friction is formed near the tip of the clip bar 3. To stop the tie, pinch the rear ends of the decoration bar 2 and the clip bar 3 to open them, position the tie and shirt between them, and release your fingers. The function of the tooth-like portion 6 prevents the tie bar 1 from slipping off the tie and slipping off. Further, as shown in FIG. 8, the decoration bar 2 and the clip bar 3 are separated without using a coil spring. There is also one manufactured by bending a metal plate 7 which is integrated and continuous. That is, the metal plate 7 is bent approximately 180 degrees, and the tie is clamped by its own elasticity. In this type of tie bar 1, when the tie is stopped, the tie is sandwiched and slid so that the tooth-like portion 6 cannot be provided on the surface of the holding portion. The type in Fig. 7 is called the crocodile type, and the type in Fig. 8 is called the hairpin type.

[0003]

[Problems to be solved by the device]

 However, in the crocodile type tie bar of FIG. 7, since the tooth-like portion 6 is formed by the tip portion of the clip bar 3, the tie bar 1 rotates and tilts with the tooth-like portion 6 as a fulcrum. There was a problem. Further, the tooth-like portion 6 may damage the tie cloth. Further, the hairpin type tie bar shown in FIG. 8 did not sufficiently rub against the tie and could not sufficiently prevent the possibility of falling out. The present invention has been made to solve the above problems, and an object of the present invention is to provide a tie bar that does not rotate, does not damage the cloth of the tie, and does not fall out when the tie bar is worn. .

[Embodiment of device]

 An embodiment of this invention will be described with reference to the drawings. Figure 1 shows the tie bar of the so-called crocodile type with this invention implemented. On the back side of the decoration bar 2 to be decorated, a metal plate material 8 having a corrugated shape 8a for increasing friction is fixed by adhesion or brazing. One of the grips of the plate member 8 is bent in a U shape, and a pin connecting portion 9 is provided. The clip bar 3 is openably and closably attached by the pin coupling portion 9. A coil spring (not shown) is attached around the pin shaft 11 of the pin coupling portion 9. The clip bar 3 is biased toward the decorative bar 2 in the closing direction by the biasing force of the coil spring. By bending the clip bar 3 into a shallow inverted V shape, almost the entire surface facing the plate member 9 is parallel to the plate member. On the surfaces in the parallel state, the shape of the corrugation 3a similar to the corrugation of the plate member 8 is applied. Both wave patterns 8a and 3a have the same phase and are formed so as to be fitted to each other.

Further, a slit 12 is formed in the longitudinal direction at the center of the clip bar 3 in the width direction at the portion of the wave shape 3 a on the clip bar 3 side. The action of this slit 12 further increases the friction on the tie. At the rear end of the clip bar 3, a slip stopper 13 for pinching with a finger is formed. As described above, by providing the corrugated shapes of the corrugations 3a and 8a on both surfaces of the portion of the tie bar that holds the tie, greater friction can be exerted on the tie than when the corrugated shape is provided on only one surface. Also, since the corrugations 3a and 8a on both sides are provided almost in the entire lengthwise direction of both bars 2 and 3, compared to the case where unevenness is provided in a part of the longitudinal direction (for example, only the tip), It is possible to prevent the tie bar 1 from rotating and inclining in this state. The lengths of the bars 2 and 3 provided with the uneven shape as described above in the longitudinal direction must be sufficiently long so that the tie bar does not rotate. However, this sufficient length is required. It is related to the weight and length of.

Further, since the uneven shape is the corrugated shape 3A, 8a, the contact area with the tie becomes large, and more friction can be exerted. In addition, it is possible to locally increase the friction at each curved portion of each corrugation, and to exert sufficient friction as a whole. Further, by fitting the corrugations 3a and 8a on both sides to each other, sufficient frictional force can be exerted against the force of falling off in the direction parallel to the bars 2 and 3. Further, even when the force is applied to the bars 2 and 3 in the direction perpendicular to them, that is, in the vertical direction, the corrugations are fitted to each other, resulting in a larger frictional force than in the case where they are simply in flat contact. Can be demonstrated. Further, the tie cloth is slightly swollen and enters the slit 12, so that the local friction between the edge portion of the inner circumference of the slit 12 and the cloth can be enhanced, and therefore the overall friction can be increased.

In the above embodiment, a so-called crocodile type tie bar was shown, but in another embodiment, the present invention can be applied to a hairpin type tie bar as shown in FIG. . That is, one metal plate member 14 like a hairpin is bent and fixed to the back side of the decoration bar 2 by adhesion or brazing. The corrugated shapes of the corrugations 3a and 8a similar to those in the above-described embodiment are provided on the fixed portion and the parallel portion facing the fixed portion. The opposite parallel portions become the clip bars 3. Even if the coil spring as in the above embodiment is not provided, the tie can be held by the spring property of the bent portion of the plate member 14 itself. The slits 12 are also formed as in the above embodiment (FIG. 1).

Since the corrugated shapes of the corrugations 3a and 8a do not have particularly large friction locally unlike the conventional tooth-like portion 6 (see FIG. 7), the corrugations 3a and 8a should be slid on the tie when worn. Is possible. Not only that, as described in the above embodiment, sufficiently large friction can be exerted as a whole. Further, it is possible to prevent the tie bar 1 from rotating and tilting in the mounted state. Although the uneven shape is wavy in the above two embodiments (FIGS. 1 and 2), it may be uneven in other shapes in other embodiments. For example, as shown in FIG. 3, a long convex portion 15 is formed on one surface to be sandwiched, that is, the plate material 8 (or 14) surface on the decoration bar 2 side, and a long concave portion is formed on the other surface, that is, the surface on the clip bar 3 side. 16 can be formed. The recess 16 may be a slit. The convex portion 15 and the concave portion 16 are fitted to each other.

By forming the protrusions 15 and the recesses 16 which are long in the longitudinal direction of the bar in this manner, the force that tends to slip off in the direction perpendicular to the longitudinal direction of the bars 2 and 3, that is, in the vertical direction, is removed. It is possible to generate a large resistance force, that is, a frictional force. That is, the tie sandwiched between the long convex portion 15 and the long concave portion 16 is bent in a U-shape, and an extremely large resistance force is generated in the bent portion. Since this bent portion exists long in the longitudinal direction of the bars 2 and 3, the resistance becomes extremely large. Further, a sufficient resistance force is generated also in the longitudinal direction of the bars 2 and 3, that is, in the lateral direction. It should be noted that the convex portion 15 and the concave portion 16 may have a gap in which the cloth of the tie is sufficiently clamped and caught in the fitted state.

Further, the embodiment of FIG. 3 can be applied not only to the crocodile type but also to the hairpin type tie bar, like the embodiments of FIGS. 4 to 6 described later. Next, as shown in FIG. 4, the concavo-convex shape may be one in which a large number of random concavities and convexities 17 are formed. The large number of irregularities 17 are fine irregularities. The fine relief avoids damaging the tie fabric. Here, the meaning of being random means that there are concavities and convexities facing each other, some of which are fitted and some of which are contacted at the tip, but there is no regularity in these fitting and contact. Even if the fine unevenness does not increase the local friction and avoids damaging the fabric of the tie, the surface on which the unevenness 17 is formed is both sides of the part that holds the tie, Moreover, since it covers almost the whole, sufficient friction can be generated as a whole. Therefore, it has substantially the same effect as the above embodiment.

Further, the uneven shape of FIG. 5 is such that a plurality of convex portions 18 are arranged in the longitudinal direction of the bars 2 and 3. The convex portion 18 constitutes a cylindrical side surface and is provided with an arcuate cross section. The positions and sizes of the protrusions 18 are the same on both sides where they are sandwiched, and therefore, they contact the protrusions 18 on the other surface facing each other at their tips. A frictional force can be increased by holding a tie between the contacting parts. Further, since the circumferential direction of the cylindrical curved surface of the convex portion 18 is oriented in the longitudinal direction of the bars 2 and 3, it is possible to secure a certain degree of slippage with the cloth of the tie in this longitudinal direction, and accordingly, the hairpin type tie. It can be easily implemented in the bar. It is also possible to change the circumferential direction of this curved surface by 90 degrees so that the curved surfaces are oriented at right angles to the longitudinal direction of the bars 2 and 3. A large resistance force is generated at the edge of the cylindrical end, and a large resistance force is generated against the slipping-off force.

Further, as shown in FIG. 6, the concavo-convex shape is such that one surface has a plurality of convex portions 19 arranged in the longitudinal direction of the bar 2 and the other surface has a plurality of concave portions 21. You can also do it. The plurality of concave portions 21 and the plurality of convex portions 19 are fitted to each other. When fitting and sandwiching the tie, the tie can be bitten by the edge portions of the concave portion 21 and the convex portion 19 to increase the friction. This edge exists on the substantially circumference of the concave portion and the convex portion, that is, on the line. It is considered that the projected length of this line portion in the longitudinal direction of the bars 2 and 3 and the projected length of the bars 2 and 3 in the direction perpendicular to the longitudinal direction are substantially equal. Therefore, not only in the longitudinal direction of the bar but also in the direction perpendicular to the longitudinal direction of the bar, a sufficiently large resistance force against the slipping-off can be generated.

It should be noted that, in the above-described embodiment, recesses and protrusions that are fitted with each other are provided on both sides where the sandwiching is performed (FIGS. 3 and 6), or similar concave and convex shapes are provided (FIGS. 4 and 5). 5), but in other embodiments, the concavo-convex shapes provided on both sides may be different from each other. That is, one surface may be provided with a corrugated shape as shown in FIG. 1 or FIG. 2, and the other surface may be provided with a concavo-convex shape with a large number of random concavities and convexities as shown in FIG. There may be a plurality of other combinations of such uneven shapes. That is, any combination is possible in FIGS. Further, the material on both sides provided with the concavo-convex shape is not limited to the conventional metal material, but may have some elasticity and can increase friction. For example, a member made of silicon rubber may be fixed to one surface or both surfaces where the sandwiching is performed. In addition, an uneven shape may be formed on this member.

[0015]

[Effect of device]

 As described above, according to the first aspect of the present invention, the tie bar can be prevented from rotating and tilting in the mounted state by providing the uneven shape for increasing the friction in almost the entire portion where the tie is held. Also, by having the uneven shape on both sides of the part that holds the tie, this uneven shape can exert a sufficiently large friction as a whole even if it does not have a large local friction so as to damage the cloth of the tie. , It is possible to prevent all tie-bars from falling out when worn. According to the invention of claim 2, since the corrugated concavo-convex shapes formed on both sides have the same phase and are fitted to each other, the area of the fitted portion can be increased and the friction of the whole with respect to the tie bar can be increased. Can be made bigger. Furthermore, by fitting in a corrugated shape, a great resistance can be exerted against the force that tends to slip off, making it difficult to slip off. In addition, a large frictional force is locally generated at the portion of each wavy curve, and these curves can generate sufficient friction without damaging the cloth like the conventional tooth-like portion. According to the invention of claim 3, the long concave portion and the long convex portion formed in the longitudinal direction of the bar are fitted to each other. Therefore, when the tie is sandwiched and fitted, a large resistance force is exerted against the force of all falling in the vertical direction. Since it is effective, it is possible to more completely prevent the tie bar from slipping off when worn. Further, according to the invention of claim 5, the convex portions formed on both surfaces of the sandwiched portion are in contact with each other, so that a large frictional force is locally generated at this contact point. Therefore, even if these uneven materials that do not damage the tie cloth, that is, those with a small coefficient of friction are used, a sufficient friction force can be obtained at the contact portion, and the tie pin as a whole can be used. Not only can it be prevented from falling off, but the fabric of the tie can also be prevented from being damaged. According to the invention of claim 6, by further fitting the plurality of protrusions into the plurality of recesses, not only the direction perpendicular to the bar, that is, the vertical direction, but also the direction parallel to the bar, that is, the horizontal direction. Also, sufficient friction can be generated against the tie bar, and the tie bar can be prevented from all coming off. According to the invention of claim 8, since the tie is held by the member made of the material having elasticity larger than that of the metal, large friction can be exerted as compared with the conventional case where the tie is held by the metal. Therefore, it is not necessary to provide a tooth-like portion as in the past, and the tie cloth is not damaged. In addition, it is possible to reduce the possibility of slipping out while wearing. Further, by providing the tie bar on almost the entire surface to be clamped, it is possible to prevent the tie bar from rotating and tilting.
