  As shown in FIG. 3, the male hook 5 is formed of a substantially convex body as a whole, and has a top portion 5A having a substantially cylindrical shape and a base end portion 5B having a disk shape. The front part 5A of the male hook 5 having a substantially cylindrical shape is provided with a protruding edge part 8 at the front end peripheral part of the front part 5A so that the front end peripheral part protrudes outward in the radial direction from the rear peripheral part 8A. (See FIG. 4).

  That is, the male hook 5 has a rear surface of the base end portion 5B in the round hole 10 formed in the engagement surface material 9A among the two engagement surface materials 9A and 9B shown in FIG. And the set screw 12 disposed between the engaging face material 9A and the engaging face material 9B is screwed into a screw hole (not shown) formed in the leg part 11, The male hook 5 is fastened to the engaging face material 9A inside the folded back lid 4 (see FIGS. 7 to 8). As a result, the male hook 5 is positioned inside the folding lid 4 in a state where the leading portion 5A is exposed (see FIG. 2). The engaging face material 9A and the engaging face material 9B are stitched together to form the folded back lid 4.

  On the other hand, the female hook 7 that can engage the leading portion 5A of the male hook 5 in the direction of arrow A in FIG. 3 has a female hole 13 that engages the leading portion 5A of the male hook 5 in the direction of arrow A. It is assumed that the entire upper surface having a circular shape has a substantially cylindrical shape, and includes a substrate 14 having a generally cylindrical shape (see FIGS. 3 and 4).

  That is, as shown in FIG. 6, the female hook 7 is formed by concentrically fixing an overall cylindrical base body 14A on an overall disc-shaped support base 14B (see FIG. 6). The base body 14A and the support base 14B are manufactured as an integrated body by molding, for example. In the base 14, a space 14 </ b> C in which the leading portion 5 </ b> A of the male hook 5 is engaged is formed by the inner surface of the base body 14 </ b> A and the surface 20 (base surface) of the support base 14 </ b> B.

  As shown in FIG. 6, the female hook 7 has a leg portion 15 formed on the rear surface of the disc-shaped support base 14 </ b> B, and two engaged surface members 16 </ b> A and 16 </ b> B constituting the front piece 6 of the second bag 2. Among them, a stopper ring 18 that is inserted between the engaged surface material 16A and the engaged surface material 16B is inserted into the round hole 17 formed in the engaged surface material 16A. It is attached and fixed to the front piece 6 (see FIG. 2). The engaged face material 16 </ b> A and the engaged face material 16 </ b> B are stitched together to form the surface piece 6.

  Here, the center position of the circular tip end surface of the top portion 5A of the male hook 5 engaged in the direction of the arrow A toward the female hole 13 is shown in FIG. 4, FIG. 5, FIG. As shown in FIG. 8, the attracting portion 24 is provided and formed in a state where a permanent magnet is embedded. On the other hand, as shown in FIGS. 4 and 6, the circular base surface 20 of the support base 14 </ b> B of the base 14 has a leading portion 5 </ b> A of the male hook 5 at a position shifted from the center 20 </ b> C in the radial direction of the base surface 20. Is provided in the state of being engaged with the inside of the base body 14 from the female hole 13, and a suctioned portion 25 that can be sucked and sucked with the suction portion 24 of the male hook 5. Here, the center 20C is the center of a substantially circular region 13A (region in which the female hole 13 is projected on the base surface 20) corresponding to the inner bottom portion of the female hole 13 in the base surface 20 of the support base 14B (FIG. 6). Match. The substrate surface 20 of the support substrate 14B constitutes the inner bottom portion of the substrate 14.

  A semicircular holding hole 19 is formed on the upper surface of the base body 14 </ b> A so as to extend to the female hole 13 in the radial direction and reach a position corresponding to the attracted portion 25. Similar to the female hole 13, the holding hole 19 is formed so as to penetrate the upper surface of the base body 14A vertically and reach the space 14C. The maximum opening diameter of the holding hole 19 is the same as or larger than the outer diameter W1 (FIG. 4) of the rear peripheral portion 8A of the male hook 5 and smaller than the outer diameter W2 (FIG. 4) of the protruding edge portion 8. Has been. On the other hand, the maximum opening diameter of the female hole 13 is the same as or larger than the outer diameter W2 of the protruding edge 8 of the male hook 5.

  As shown in FIGS. 7 and 8, the attracted portion 25 is formed by embedding a permanent magnet in the support base 14B. The adsorbed part 25 is arranged in a substantially circular area 19A corresponding to the inner bottom part of the holding hole 19 (an area where the holding hole 19 is projected on the substrate surface 20) (FIG. 6) in the base surface 20 of the support base 14B. In other words, at least the center position of the attracted portion 25 is shifted from the center 20 c of the substrate surface 20. Here, the attracted portion 25 is configured to apply an attractive force having a polarity (S pole) different from the magnet polarity (for example, the N pole) of the attracting portion 24 on the tip surface of the leading portion 5A of the male hook 5. . Further, when the attracted portion 25 is disposed outside the inner bottom portion of the female hole 13, even if the male hook 5 engaged with the female hook 7 is moved up and down by the suction force of the attracted portion 25, the protruding edge portion 8 hits the holding hole 19, and the male hook 5 is difficult to come out of the female hole 13, which is preferable.

  The female hole 13 of the base body 14 is formed with a slit 28 that extends in a radial direction from a position opposite to the holding hole 19 in the circumferential direction (θ direction in FIG. 4). The slit 28 vertically penetrates the upper surface of the base body 14A, extends in the radial direction (radial direction) of the base body 14A, and communicates with the outside on the peripheral wall 14D of the base body 14. The opening width of the slit 28 is equal to or larger than the outer diameter W1 of the rear peripheral portion 8A of the male hook 5 and smaller than the outer diameter W2 of the protruding edge portion 8.

  According to the above configuration, when the leading portion 5A of the male hook 5 is engaged from the female hole 13 into the space 14C as shown in FIG. 7, the suction portion 24 and the support base 14B provided on the leading end surface of the leading portion 5A are attached. The male hook 5 moves in the direction of the arrow D1 (FIG. 8) in the space 14C by a magnetic attraction force acting between the portion to be attracted 25 provided. Then, the male hook 5 stops at a position where the attracting part 24 and the attracted part 25 face each other as shown in FIG. 8, and this position is generated by the suction force between the attracting part 24 and the attracted part 25. As a result, the male hook 5 and the female hook 7 are engaged with each other. In this state, even if the male hook 5 is moved upward (upward in FIG. 8) due to the relationship between the outer diameter W2 of the protruding edge 8 and the opening diameter of the holding hole 19, the protruding edge 8 is Since it strikes against the inner surface of the holding hole 19, the leading portion 5 </ b> A of the male hook 5 cannot be pulled out of the base body 14, and the engaged state is held by the suction force between the suction portion 24 and the suctioned portion 25. .

On the other hand, the male hook 5 is moved in the arrow D2 direction opposite to the arrow D1 direction, and the male hook 5 is moved upward in a state where the head portion 5A of the male hook 5 is disposed at the position of the female hole 13. , The male hook 5 can be taken out from the female hole 13 due to the relationship between the outer diameter W2 of the protrusion 8 and the opening diameter of the female hole 13, and the male hook 5 and the female hook 7 The engaged state can be released.
The engagement between the male hook 5 and the female hook 7 can also be released by taking out the male hook 5 moved in the arrow D2 direction through the slit 28 to the outside.

  As a result, the male hook 5 and the female hook 7 can be engaged and disengaged with a simple operation while having a simple configuration, thereby providing an engagement tool with excellent operability and durability. can do.

  In the above embodiment, the holding hole 19 is semicircular, but the opening size is the same as or larger than the outer diameter W1 (FIG. 4) of the rear peripheral portion 8A of the male hook 5 and As long as it is smaller than the outer diameter W2 (FIG. 4), it may have a shape other than this, for example, a slit shape.

Moreover, according to the said embodiment, although the adsorption | suction part 24 is formed so that a permanent magnet may be embed | buried in the center part of the front end surface which makes | forms the circle in the head part of the male hook 5, for example, a permanent magnet is formed in the whole front end surface. And the entire tip surface may be used as the suction portion 24.
Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.

  As described above, the present invention allows the male hook to be disengaged from the female hook by a simple operation without the male hook easily detaching from the female hook even when some external force is applied on the male hook side. Therefore, it can be applied to various products such as wallets and second bags that require an engaging tool.
