Yes, installation is not complete. Since the operation knob portion 84 does not intersect the hole edge portion 51, the mat 12 can be removed.

  As shown in FIG. 9A, the inner peripheral protrusion 64 is inserted into the hole edge 51. Further, as shown in FIG. 9B, the protruding portion 42 is also inserted into the hole edge portion 51. Since the lower end of the operation knob portion 84 is above the hole edge portion 51 and the restriction portion 44, the operation knob portion 84 can rotate. The limiter 44 limits the downward movement of the operation knob 84 in the axial direction. The outer peripheral taper 88 and the inward protrusion 25 are engaged.

  Returning to FIG. By rotating the operation knob portion 84, the operation knob portion 84 and the hole edge portion 51 intersect with each other to be in a locked state. A state where the operation knob portion 84 shown in FIG. 9A is rotated by 90 degrees is the mat fastener 10 in the locked state shown in FIG. In the locked state, the operation knob portion 84 and the hole edge portion 51 intersect with each other, and the operation knob portion 84 prevents the front-side second fixing member 50 from coming off. In this way, the mat 12 can be connected to the carpet 14.

  As shown in FIG. 1A, the protrusion 42 is positioned in the knob insertion hole 53. The knob insertion hole 53 has a shape that is slightly larger than the outer shape of the protrusion 42. The longitudinal direction of the operation knob portion 84 and the longitudinal direction of the limiting portion 44 are parallel. As shown in FIG. 1B, the shaft portion 82 is supported by the elastic portion 24 in a state where the operation knob portion 84 is slightly lifted with respect to the hole edge portion 51 and the protruding portion 42. The operation knob 84 is in a state of being lifted from the hole edge 51 by 1 mm to several mm. The lower end of the operation knob portion 84 and the hole edge portion 51 have a predetermined gap in a normal locked state.

FIG. 10 is a cross-sectional view showing a state where the operation knob portion 84 is pushed toward the opening edge on one end side of the insertion hole portion 28. That is, the mat fastener 10 shown in FIG. 1 is in a normal locked state, and in FIG.

  When an external force is applied to the operation connecting member 80 from above, the operation knob portion 84 falls, and the lower end of the operation knob portion 84 comes into contact with the hole edge portion 51 and stops as shown in FIG. At this time, the outer peripheral taper portion 88 of the shaft portion 82 expands the elastic portion 24 against the elastic force of the elastic portion 24. Since the inward protruding portion 25 of the elastic portion 24 abuts on the outer peripheral tapered portion 88 and biases in the closing direction, the outer peripheral tapered portion 88 is biased upward in the axial direction.

  As shown in FIG. 10B, the restricting portion 44 is disposed near the side edge of the operation knob portion 84, and the rotation of the operation knob portion 84 is restricted. For this reason, the state where the operation knob portion 84 intersects the hole edge portion 51, that is, the locked state is maintained. Thereby, it can suppress that the operation knob part 84 rotates with the force with respect to the operation knob part 84 from the axial direction upper direction, and can suppress that the mat | matte 12 remove | deviates from the carpet 14. FIG. The restricting portion 44 can be disposed so as to protrude above the hole edge 51 by allowing the protrusion 42 to be inserted into the hole edge 51.

  When the external downward force in the axial direction on the operation connecting member 80 is released, the operation connecting member 80 moves upward in the axial direction by the restoring force of the elastic portion 24, and as shown in FIG. And stop by contact of the bulging portion 86. In this manner, the shaft portion 82 is pushed back by the elastic portion 24, and the operation connecting member 80 returns to the original position. The operation connecting member 80 can be easily pushed back with a simple shape by the outer peripheral tapered portion 88 and the inward protruding portion 25.

  In the normal locked state, the elastic portion 24 again holds the position of the operation connecting member 80, and the operation knob portion 84 is positioned above the limiting portion 44, so that the user can unlock the lock by rotating the operation knob portion 84. Can do.

  Although the restricting portion 44 is formed on the upper surface of the protruding portion 42, a restricting portion that restricts the rotation of the operation knob portion 84 may be further formed on the upper surface of the hole edge portion 51. That is, a limiting portion that limits the rotation of the operation knob portion 84 is also provided on the second fixing member 50 side. A limiting portion that protrudes upward may be formed on the upper surface of the hole edge portion 51 and in the vicinity of the outer periphery of the operation knob portion 84, and the height of the limiting portion may be the same position as the limiting portion 44. Thereby, when the operation knob part 84 falls, rotation of the operation knob part 84 can be restrict | limited more reliably.

  The limiting portion 44 is formed in the first fixing member 20 and is provided at a position surrounded by the hole edge portion 51. Further, as shown in FIG. 1A, the restriction portion 44 is formed with respect to the rotation locus of the operation knob portion 84 by forming the restriction portion 44 so as to be orthogonal to the longitudinal direction of the hole edge portion 51. It becomes easy to overlap, and the rotation limitation of the operation knob portion 84 can be easily made. Therefore, even if there is a manufacturing error or the like, the rotation of the operation knob portion 84 can be surely restricted.
