It is being touched. Further, on the front surface of the mounting portion 21, convex portions 23 are formed on both sides of the insertion hole 22. On the other hand, at the lower end of the hook 2, a substantially semicircular hanging portion 24 for hanging a hanger or the like is formed.

The fixed knob 3 is formed by molding a hard resin, and has a head 31 as shown in FIG. A circular protrusion 32 is formed at the center of one end surface of the head 31. The height of the circular protrusion 32 is higher than the height of the protrusion 23, and the outer diameter thereof is substantially equal to the distance between the two protrusions 23. Further, two locking projections (locking portions) 33A, 33B are formed on the outer peripheral portion of the one end surface of the head 31 at 180 ° apart in the circumferential direction. Each of the locking protrusions 33A and 33B has the same height as the circular protrusion 32, and the end portion on the inner peripheral side thereof is continuous with the circular protrusion 32.

Further, cam surfaces 34A and 34B are respectively formed on portions of the one end surface of the head portion 32 which are located between the two locking projections 33A and 33B. In each of the cam surfaces 34A, 34B, a step amount (hereinafter, simply referred to as a step amount) between each part of the cam surface 34A, 34B and the tip end surface of the locking projection 33A (33B) is one direction in the circumferential direction (see FIG. It is inclined so that it becomes smaller as it goes in the direction of arrow B). Therefore, the amount of step difference on one cam surface 34A is large on the side of the locking projection 33A and small on the side of locking projection 33B, and the amount of the step on the other cam surface 34B is small on the side of the locking projection 33B. It is large on the side and small on the side of the locking projection 33A. The maximum step amount of each cam surface 34A, 34B is larger than the height of the convex portion 23, and the minimum step amount is smaller than the height of the convex portion 23.

Further, a shaft portion 35 having a circular cross section is formed at the center of the circular protrusion 32. The length of the shaft portion 35 is substantially the same as the total thickness of the horizontal bar 1 and the hook 2. The outer diameter of the shaft portion 35 is substantially the same as the width thereof so that the shaft portion 35 can be rotated while being inserted into the mounting hole 12 and the insertion hole 22.

An engaging portion 36 is formed at the tip of the shaft portion 35. The engaging portion 36 has a rectangular shape having substantially the same shape and approximately the same size as the engaging hole 12 and the insertion hole 22 so that the engaging portion 36 can be inserted into the attaching hole 12 and the through hole 22. It is formed to be located. Further, the engaging portion 36 is aligned with the mounting hole 12 when the convex portions 23, 23 are abutted against the side surface of the side surface of each of the locking projections 33A, 33B on the side having the larger step difference. It is arranged and formed so that it can be inserted.

Next, in the hook device having the above structure, a case where the hook 2 is fixed to the horizontal bar 1 will be described. First, as shown in FIG. 1 (A), the hook 2 is attached to the horizontal bar 1 so that the insertion hole 22 is aligned with the attachment hole 12. Next, holding the head portion 31 of the fixed knob 3, the engaging portion 36 is sequentially inserted into the insertion hole 22 and the attachment hole 12 (see FIG. 1C). In this state, since the convex portion 23 is located at the position where the step difference between the cam surfaces 34A and 34B is the largest, the cam surfaces 34A and 34B and the convex portion 23 are not in contact with each other, and the circular protrusion 32 and the locking portion. The protrusions 33A and 33B are in contact with the hook 2.

Next, as shown in FIG. 1B, the fixed knob 3 is rotated in one direction (clockwise in FIG. 1) by approximately 90 °. Then, the longitudinal direction of the engaging portion 36 comes to face the lateral direction of the mounting hole 12 (see FIG. 1D), and the engaging portion 36 cannot pass through the mounting hole 12 and cannot be pulled out. Engage with. Further, when the fixed knob 3 is rotated, the cam surfaces 34A and 34B abut the tip surfaces of the convex portions 23 and 23, and the head 31 is pressed so as to move from the lateral bar 1 side to the hook 2 side. At this time, since the engaging portion 36 is engaged with the lateral bar 1, the engaging portion 36 and the head 31 sandwich and fix the lateral bar 1 and the hook 2. That is, the hook 2 is fixed to the horizontal bar 1.

Next, when releasing the fixing of the hook 2, the fixing knob 3 is rotated in the other direction. Then, when the locking projections 33A and 33B are brought into contact with the projection 23, the engagement portion 36 is aligned with the mounting hole 12.

When the engaging portion 36 is pulled out from the mounting hole 12 and the insertion hole 22 in order to release the fixation, the engaging protrusions 33A and 33B are brought into contact with the convex portions 23 and 23 so that the engaging portion 36 is released. Can be aligned with the mounting hole 12 and the insertion hole 22. Therefore, the engaging portion 36 can be pulled out from the mounting hole 12 and the insertion hole 22 very easily. In particular, in this embodiment, since the convex portions 23, 23 are in contact with the outer circumference of the circular protrusion 32, the engaging portion 36 can be more accurately aligned with the mounting hole 12, and the engaging portion 36 can be further improved. Can be easily removed.

It should be noted that the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the invention. For example, in the above embodiment, the mounting hole 12 is formed in a rectangular shape, but may have another shape as long as it has a non-circular cross section.

Further, in the above embodiment, the insertion hole 22 is formed in the same shape as the mounting hole 12, but as long as the engaging portion 36 can be inserted and the size is smaller than the head portion 31. The shape different from the mounting hole 12, for example, a circular shape may be used. However, when the insertion hole 22 has the same shape as the mounting hole 12, when the engaging portion 36 is inserted from the hook 2 side into the mounting hole 12, the engaging portion 36 is attached with the insertion portion 22 being inserted. It can be inserted into the hole 12 and can be easily inserted into the mounting hole 12. Therefore, it is desirable to do so.

Further, in the above embodiment, the protrusion 2 is formed on the hook 2 and the locking projections (locking parts) 33A and 33B and the cam surface 36 are formed on the fixture 3, but the reverse. Alternatively, the hook 2 may be provided with a locking portion and a cam surface, and the fixture 3 may be provided with a convex portion.
