As shown in FIG. 4C, the insertion hole 22 has a tapered portion 38 that expands toward the inlet on the side surface. This facilitates insertion of the knob 50.

  5A is a perspective view of the knob 50 as viewed from the front surface, and FIG. 5B is a perspective view of the knob 50 as viewed from the back surface. 6A is a surface view of the knob 50, and FIG. 6B is a cross-sectional view of the knob 50 of the line segment DD shown in FIG. 6A. The knob 50 includes a knob main body 52, an elastic piece 58, a hinge portion 56, and a connecting portion 66, which are integrally formed as a single member. The knob main body 52 includes a handle portion 54 for a user to hold, and two suspension portions 68 for suspending the handle portion 54 and the hinge portion 56.

  As shown in FIG. 5 (b), the connecting portion 66 is formed on the back surface of the suspension portion 68 of the knob main body portion 52 and is rotatably connected to the curtain member 16. The connecting portion 66 functions as a stopper by contacting the edge of the insertion hole 22 when the knob 50 is inserted into the insertion hole 22. Accordingly, the curtain member 16 can be raised to the vicinity of the edge of the insertion hole 22, and the gap between the curtain member 16 and the holder 20 can be reduced. The handle 54 is provided on the rear side in the insertion direction of the knob body 52, and a plurality of recesses are formed on the surface. The insertion direction of the knob 50 is the longitudinal direction of the knob 50.

  The hinge part 56 is provided in the insertion direction front side of the knob main body part 52, and supports the elastic piece 58 rotatably. The hinge portion 56 is provided at the front end portion of the knob main body portion 52 and gives elasticity to the elastic piece 58 by twisting. It is inserted into the insertion hole 22 from the hinge portion 56 at the front in the insertion direction.

  The elastic piece 58 is connected to the hinge portion 56 and extends from the hinge portion 56 toward the handle portion 54 side. The elastic piece 58 is accommodated between the two suspension portions 68, and the knob body portion 52 and the elastic piece 58 are formed in a plate shape as a whole. A gap 70 is formed between the elastic piece 58 and the handle portion 54 and the suspension portion 68 as shown in FIG. 6A, and the end of the elastic piece 58 on the handle portion 54 side as shown in FIG. 6B. The part is a free end.

  As shown in FIG. 5A, a release operation part 60, a locked part 64, and a notch part 62 are formed on the surface of the elastic piece 58, respectively. The locked portion 64 is formed to be recessed in the width direction, and is locked by the protruding locking portion 28. Although the locked portion 64 and the connecting portion 66 are in the front and back positions, they are arranged at the same interval from the hinge portion 56 in the longitudinal direction of the knob 50. The release operation part 60 is provided on the grip part 54 side from the locked part 64, and a plurality of convex parts are formed on the operation surface.

  As shown in FIG. 6B, the notch 62 is formed by cutting out the elastic piece 58 in front of the locked portion 64 in the insertion direction. Since the notch 62 cuts out the front edge of the knob 50 so that the thickness of the knob 50 is thinner than the suspension 68, the insertion into the insertion hole 22 provided with the locking portion 28 at the entrance becomes easy. Further, the notch 62 is formed with inclined surfaces on both sides in the width direction of the elastic piece 58. That is, the notch 62 is inclined so that the elastic piece 58 becomes thicker toward the side in the width direction. As a result, when the locking portion 28 is introduced into the notch space of the notch 62 when the knob 50 is inserted into the insertion hole 22, the width of the locking portion 28 is increased by the inclined surfaces on both sides of the notch 62. Relative movement can be restricted, and lateral shift when the knob 50 is inserted into the holder 20 can be suppressed. The width direction is a direction parallel to the rotation axis direction of the connecting portion 66 and is a direction orthogonal to the longitudinal direction of the knob 50.

  Operations of the holder 20 and the knob 50 configured as described above will be described with reference to FIGS. 7 and 8. FIG. 7 is a view showing the fastener 10 in a state where the knob 50 is locked to the holder 20. 7A is a view of the fastener 10 viewed from the back side, FIG. 7B is a view of the side surface, and FIG. 7C is a line segment EE shown in FIG. 7A. It is sectional drawing of the fastener 10. FIG. Moreover, Fig.8 (a) is sectional drawing of the fastener 10 of the line segment FF shown to FIG.7 (b), FIG.8 (b) is the line segment GG shown to FIG.7 (b). It is sectional drawing of the fastener 10. FIG.

  The knob 50 is inserted into the insertion hole 22 of the holder 20 from the hinge portion 56 by the user holding the handle portion 54. The user inserts the locking portion 28 so that the surface of the notch 62 is aligned. Since the locking portion 28 is exposed to the outside, it is easy to match the surface of the notch 62, and the locking portion 28 can be easily introduced into the locked portion 64 adjacent to the notch 62. At this time, since both sides of the notch 62 are inclined, even if the knob 50 is displaced in the width direction, the locking portion 28 and both sides of the notch 62 abut against each other to restrict the movement in the width direction. The locking portion 28 can be easily introduced into the locked portion 64.

  Further, when the knob 50 is inserted and the locking part 28 crosses the mountain that becomes the boundary between the notch part 62 and the locked part 64, the elastic piece 58 rotates around the hinge part 56, and the locked part 64. Goes down. When the locking portion 28 is accommodated in the locked portion 64, the elastic piece 58 returns to the original state by the elastic force of the hinge portion 56, and the locking portion 28 engages the locked portion 64 as shown in FIG. Stop. Due to this elasticity, a click feeling indicating that it is locked is transmitted to the user. Even if the knob 50 is further inserted, the connecting portion 66 comes into contact with the edge of the hole lower surface 34 and the movement of the knob 50 in the insertion direction is restricted.

  As shown in FIGS. 7C and 8B, the upper surface of the suspension portion 68 is supported in contact with the guide portion 30. FIG. 7C is also a cross-sectional view of the fastener 10 taken along line HH shown in FIG. As shown in FIG. 8B, the lower surface of the suspension portion 68 is supported in contact with the hole lower surface 34. By supporting the suspension portion 68 from above and below in this manner, the rattling of the knob 50 in the locked state can be suppressed, and the large curtain member 16 can also be fastened with one fastener 10.

  Further, since the entire plate-like knob 50 is inserted into the insertion hole 22 extending obliquely upward with respect to the horizontal direction, as seen from the back side and the side as shown in FIGS. 7 (a) and (b). Also, the knob 50 is locked in a protruding state. That is, the pulling force of the curtain member 16 is applied to the knob 50 in the vertical direction, but the pulling force can be distributed and held on the guide portion 30 and the hole lower surface 34 in addition to the locking portion 28. Thereby, the knob 50 can be locked more stably.

  As shown in FIGS. 7B and 8A, the release operation unit 60 is exposed in the locked state. Here, since the connecting portion 66 also functions as a stopper that restricts movement of the knob 50 in the insertion direction, a part of the suspension portion 68 on the rear side in the insertion direction from the connecting portion 66 can be released as a portion that can be gripped by the user. The operation part 60 and the handle part 54 can be secured. When releasing the lock, the user can easily release with one hand by pressing the release operation part 60 with the thumb while holding the handle part 54. When the two fasteners 10 are attached to the curtain member 16, they can be released simultaneously with both hands. The thickness of the suspension portion 68 on the rear side in the insertion direction from the connecting portion 66 is set to a thickness that does not hinder the release operation of the release operation portion 60. For example, the release operation is greater than the height of the locking portion 28 or the locked portion 64. It may be formed thicker than the portion 60.

  Further, as shown in FIG. 5A, a plurality of concave portions are formed on the surface of the handle portion 54, and a plurality of convex portions are formed on the operation surface of the release operation portion 60. As a result, a recessed portion is formed so that the portion to be grasped is easy to grasp, and a portion to be pressed at the time of release is convex like a button, so that it is designed so that the user can easily grasp the usage method.
