As shown in FIG. 5, the buckle 1 for a shoe belt includes a first fastener 11 attached to one belt 52 of the shoe 51 and a second fastener 31 attached to the other belt 53 of the shoe 51. Become. As shown in FIG. 3, the first fastener 11 and the second fastener 31 have contact surfaces 12a and 32a that are in contact with each other, and at least one of the contact surfaces 12a and 32a has contact surfaces 12a, Magnets 20 and 40 are provided for attracting 32a to each other by magnetic force.

  As shown in FIG. 1, the first fastener 11 has a pair of inner locking holes 23, 24 provided on the attachment side (attachment shaft 17 side) of one belt 52, and the opposite attachment side of one belt 52. A pair of outer locking holes 21 and 22 are provided in 12c. As shown in FIG. 2, the second fastener 31 is provided with a pair of inner locking projections 41, 42 on the attachment side (attachment shaft 36 side) of the other belt 53, and the other attachment side of the other belt 53. A pair of outer locking projections 43 and 44 are provided on 32d.

  As shown in FIG. 3, when the second fastener 31 is attracted to the first fastener 11 by the magnetic force of the magnets 20, 40, the pair of inner locking protrusions 41, 42 form the first fastener 11. The pair of outer locking holes 21 and 22 are locked, and the pair of outer locking protrusions 43 and 44 are locked to the pair of inner locking holes 23 and 24 of the first fastener 11. The inner locking projections 41 and 42 of the second fastener 31 are formed with a rectangular shaft having a rectangular cross section, and the outer locking holes 21 and 22 of the first fastener 11 are rectangular in cross section. It is formed with a rectangular hole.

  As described above, when the second fastening member 31 is attracted to the first fastening member 11 by the magnetic force of the magnets 20 and 40, the pair of inner locking protrusions 41 and 42 is connected to the first fastening member 41. The pair of outer locking protrusions 21 and 22 are locked to the pair of outer locking holes 21 and 22, and the pair of outer locking protrusions 43 and 44 are locked to the pair of inner locking holes 23 and 24 of the first fastener 11.

  In the shoe belt buckle 1, the pair of inner locking projections 41 and 42 and the pair of outer locking projections 43 and 44 correspond to the tensile force in the longitudinal direction of the belts 52 and 53. The force of the magnets 20 and 40 corresponds to the force substantially perpendicular to the direction, that is, the direction in which the first fastener 11 and the second fastener 31 are separated, so that the connection is not released.

In some cases, the rear end is inclined as a fulcrum. In such a case, due to the principle of the lever, a force more than the magnetic force for attracting the second fastener 31 and the first fastener 11 acts, and the tip 32d of the second fastener 31 moves from the first fastener 11. The pair of outer locking protrusions 43 and 44 of the second fastener 31 are likely to be extracted from the pair of inner locking holes 23 and 24 of the first fastener 11.

  However, the inner locking projections 41 and 42 of the second fastener 31 are formed with a rectangular shaft having a rectangular cross section, and the outer locking holes 21 and 22 of the first fastener 11 have a rectangular cross section. Since it is formed with a rectangular hole, the pair of inner locking projections 41, 42 of the second fastener 31 is difficult to be pulled out from the pair of outer locking holes 21, 22 of the first fastener 11 due to frictional resistance. Therefore, the second fastener 31 cannot be easily detached from the first fastener 11.

  As described above, the shoe belt buckle 1 has rectangular shapes of the locking projections 41 and 42 and the locking holes 21 and 22 of the first fastener 11 and the second fastener 31 connected by the magnets 20 and 40. By adopting the shape, it is possible to increase the frictional resistance so that the connection between the first fastener 11 and the second fastener 31 cannot be easily released.

  Note that the shoe belt buckle 1 has outer locking protrusions 43 and 44 of the second fastener 31 formed of a rectangular shaft having a rectangular cross section, like the inner locking protrusions 41 and 42. If the inner locking holes 23 and 24 of one fastener 11 are formed as rectangular holes having a rectangular cross section, like the outer locking holes 21 and 22, the frictional resistance is further increased and the connection is further strengthened. Can do.

  In the shoe belt buckle 1, the outer locking projections 43 and 44 of the second fastener 31 are formed by a circular shaft having a circular cross section, and the inner locking holes 23 and 24 of the first fastener 11 are formed. If the cross section is formed by a circular hole having a circular cross section, alignment can be facilitated.

  In the shoe belt buckle 1, the inner locking projections 41 and 42 of the second fastener 31 and the outer locking holes 21 and 22 of the first fastener 11 are in surface contact with each other in the longitudinal direction of the belt. Since the resistor is formed so as to come into great contact, it is more difficult to release the connection.

They are arranged in the (Y direction). The inner locking protrusions 41 and 42 and the outer locking protrusions 43 and 44 are provided to face each other with the magnet 40 interposed therebetween.

  The inner locking protrusions 41 and 42 are rectangular axes having a rectangular (rectangular) cross section, the long sides are directed in the left-right direction (Y direction), and the short sides are directed in the front-rear direction (X direction). . The outer locking protrusions 43 and 44 are circular shafts with a circular cross section, but the inner locking protrusions 41 and 42 may be rectangular axes with a rectangular (rectangular) cross section.

  Next, the use of a shoe belt buckle will be described. As shown in FIG. 5, the 1st fastener 11 is attached to the front-end | tip of the shorter short belt 52 of shoes 51, such as a high heel, by sewing. That is, as shown in FIG. 3, the first fastener 11 is attached by sewing one end (upper surface) 12 a upward and sewing the end of the short belt 52 to the attachment shaft 17 of the attachment portion 15. It is done. The other surface (lower surface) 12b of the first fastener 11 is a contact surface on the foot side.

  As shown in FIG. 5, the second fastener 31 is attached to the front portion 53 a of the longer belt 53 of the shoe 51 by engagement of the belt hole 55 and the attachment shaft 36. That is, as shown in FIG. 3, the second fastener 31 is attached to the rear end 32c of the fastener body 32 with the front portion 53a of the long belt 53 facing downward on one surface (lower surface) 32a. It passes through the frame 34 from below and passes through the guide frame 35 formed at the front end 32d of the fastener body 32 from above so as to contact the other surface 32b of the fastener body 32, and into the belt hole 55. The attachment shaft 36 is engaged and attached to the long belt 53. The second fastener 31 can adjust the length of the long belt 53 depending on the position of the belt hole 55 with which the attachment shaft 36 is engaged.

  The shoe belt buckle 1 is configured such that when one surface (lower surface) 32a of the second fastener 31 is overlapped with one surface (upper surface) 12a of the first fastener 11, the magnet 20 of the fastener body 12 and the fastener. The magnet 40 of the main body 32 is attracted by the magnetic force, and the one surface (lower surface) 32a of the second fastener 31 and the one surface (upper surface) 12a of the first fastener 11 are firmly connected.

  The rear portion 37 of the mounting shaft 36 of the second fastener 31 can be stored in the semicircular recess 13 of the first fastener 11. The pair of inner locking projections 41, 42 of the second fastener 31 are inserted into and locked to the pair of outer locking holes 21, 22 of the first fastener 11. The outer locking projections 43 and 44 are inserted into the pair of inner locking holes 23 and 24 of the first fastener 11 and locked.

  In the shoe belt buckle 1, the first fastener 11 cannot move, but the second fastener 31 can move. In other words, since the first fastener 11 is sandwiched and fixed between the foot and the second fastener 31, it cannot move in a direction away from the second fastener 31. In the shoe belt buckle 1, when a force is applied in the longitudinal direction of the belts 52 and 53, the inner locking projections 41 and 42 of the second fastener 31 are connected to the outer locking holes 21 and 22 of the first fastener 11. Since the outer locking projections 43 and 44 of the second fastener 31 are locked in the inner locking holes 23 and 24 of the first fastener 11, the second fastener 31 is 1 does not come off from one fastener 11.

In such a case, the outer locking projections 43 and 44 of the second fastener 31 are pulled out from the inner locking holes 23 and 24 of the first fastener 11.

  However, the inner locking projections 41 and 42 of the second fastener 31 are located on the fulcrum side (rear end 32c side) from the outer locking projections 43 and 44, and thus move from the outer locking projections 43 and 44. Is small and is difficult to be pulled out from the outer locking holes 21 and 22 of the first fastener 11. Moreover, since the inner locking projections 41 and 42 of the second fastener 31 and the outer locking holes 21 and 22 of the first fastener 11 have a rectangular cross section, the inner locking projections 41 and 42 The frictional resistance due to surface contact between the outer locking holes 21 and 22 and the outer locking holes 21 and 22 is large, and the inner locking protrusions 41 and 42 are more difficult to be pulled out from the outer locking holes 21 and 22. As described above, since the inner locking protrusions 41 and 42 of the second fastener 31 are difficult to be pulled out from the outer locking holes 21 and 22 of the first fastener 11, the second fastener 31. Even if it is tilted, it does not easily come off from the first fastener 11.

  In the above embodiment, since the first fastener 11 and the second fastener 31 are formed of a ferromagnetic material, a magnet is provided on either the fastener body 12 or the fastener body 32. For example, the magnets are attracted to each other by one of the magnets, and it is not necessary to provide magnets in both the fastener body 12 and the fastener body 32. Moreover, since the 1st fastener 11 and the 2nd fastener 31 mutually adsorb | suck with the magnets provided in both the fastener main body 12 and the fastener main body 32, you may form with a nonmagnetic material. Absent.

  The present invention can be used for a shoe belt buckle for connecting a belt provided on a shoe such as a high heel.
