Is formed by the inner walls (23) C, (23) C of the arcuate locking grooves (23), (23) from the inner end of the expanded portion (23) A, (23) A. The parts (23) B and (23) B are formed, and as shown in FIG.
3) C, (23) C is the arcuate locking groove from the expanded portion (23) A, (23) A
It has inclined lower surfaces (23) D and (23) D extending to the other ends of (23) and (23). Expanded portions (23) A, (23) A of the arcuate locking grooves (23), (23)
The diameter of the narrow portion (23) B, (2) is set to be approximately equal to or slightly larger than the diameter of the large diameter portion (14) of the locking rod (12) of the fixing member (1).
3) The width of B is smaller than the diameter of the large diameter portion (14) of the locking rod (12) and is substantially equal to or slightly larger than the diameter of the small diameter portion (13).

The insertion member (3) is an insertion hole portion of the locking member (2).
It has a cylindrical shape that roughly corresponds to (21).
Is formed, and a shaft (31) is extended from the center of the surface, and the shaft (31) includes a large diameter portion (31) A and a small diameter portion (31) B.
Fitting holes (32) and (32) into which the tips (16) of the locking rods (12) and (12) of the fixing member (1) are fitted respectively are provided around (31). The fitting holes (32), (32) have a conical shape adapted to the shape of the tips (16) of the locking rods (12), (12).

The rotary connector F having the above structure is made of plastic, metal or the like, but the insertion hole (2) of the locking member (2) is used.
The insertion member (3) is inserted into 1) and the shaft (31) of the insertion member (3) is fitted into the shaft hole (22) of the locking member (2). In this state, the large diameter portion (31) A of the shaft (31) of the insertion member (3) fits into the large diameter portion (22) A of the shaft hole (22) of the locking member (2), The insertion member (3) does not separate from the insertion hole (21) of the locking member (2), and thus the locking member (2) and the insertion member (3) are It is assembled so that it can rotate about 31). However, the insertion hole (2) of the locking member (2)
The protrusions (21) A, (21) A of 1) and the corrugated shape (3) A of the insertion member (3)
Free rotation is prevented by friction with.

In this state, the locking member (2) and the fixing member
A pair of articles (4), (5) to be connected as shown in FIG. 1 are sandwiched between (1) and the article (4), (5), as shown by the solid line in FIG. The locking rods (12) and (12) of the fixing member (1) to the arcuate locking grooves (23) and (23) A of the locking member (2).
(23) Penetrate from position A, and insert the tip (16) into the insertion member (3).
It is fitted into the fitting holes (32) and (32). At this time, the diameters of the enlarged diameter portions (23) A, (23) A of the arcuate locking grooves (23), (23) are the same as those of the fixing member (1).
Since the diameter of the locking rod (12) is substantially equal to or slightly larger than the diameter of the large diameter portion (14) of the locking rod (12), the large diameter portion (14) has the arcuate locking grooves (23), ( It is possible to pass through the expanded parts (23) A and (23) A of 23).

Next, when the locking member (2) is rotated in the direction of the arrow in FIG. 2, the locking rods (12), (12) of the fixing member (1) are in the arc shape as shown by the dotted line in FIG. Narrow part of locking grooves (23), (23)
It is located at (23) B, (23) B. In this state, the locking rod (12),
Since the diameter of the large diameter portion (14) of (12) is larger than the width of the narrow portion (23) B, (23) B, the large diameter portion (14) has the narrow portion (23) B, ( 23) I can't get through B. In this way, the fixing member (1) of the rotary connection tool F is engaged with the locking member (2) and
(4), (5) Connect each other.

A second embodiment of the present invention is shown in FIGS. In this embodiment, the fixing bracket (1) A of the rotary coupling F is attached to the base (11) A from the bottom of the mounting bracket.
(6) is integrally extended, and the curtain suspender (7) is attached to the mounting bracket (6).

12 and 13 show a third embodiment of the present invention. In this embodiment, locking rods (12) A, (12) A which are connected in the base (11) B of the fixing member (1) B and are U-shaped are used. The tips of 12) A and (12) A are bulged into hemispheres to become large diameter parts (14) A and (14) A. Small diameter part (13) A, (1
3) It is A. And the insertion hole (32) of the insertion member (3) A
A and (32) A are correspondingly hemispherical. In addition, as shown in FIG. 13, the arcuate locking grooves (23) D, (2
3) D does not have the inner walls (23) C, (23) C formed as in the first embodiment, but the inner walls (23) C, (23) E and the narrowed portion (2) are themselves formed.
3) F and (23) F are formed. A corrugated shape (2) C is formed on the peripheral surface of the locking member (2) B for friction. In this embodiment, since the connecting portions of the U-shaped locking rods (12) A, (12) A are located inside the base (11) B of the fixing member (1) B,
The base (11) B is reinforced.

FIG. 14 shows a fourth embodiment of the present invention. In this embodiment, the tip of the locking rod (12) B of the fixing member is a wide flat large-diameter portion (14) B, and the locking rod (12) above the large-diameter portion (14) B. The B body is the small diameter part (13) B.

FIG. 15 shows a fifth embodiment of the present invention. In this embodiment, the locking bar (12) C hung from the rear surface of the base (11) C of the fixing member (1) C has two circumferential grooves (15) A, (1
5) B is formed, and as a result, the two small steps (13) C, (13) D
And the large diameter parts (14) C and (14) D exist. In this embodiment, the fixing member (1) C can be engaged with the engaging member (2) in two steps.

FIG. 16 shows a sixth embodiment of the present invention. In this embodiment, a small waveform is formed on the peripheral surface of the engaging member (2) D.
(2) E is formed, and three protrusions (21) B, (21) B, (21) B are formed on the peripheral wall of the insertion hole (21) A at intervals of 120 °, The inner walls (23) C and (23) C as in the first embodiment are not formed in the arcuate locking groove (23) H, and the arcuate locking groove (23) H itself is enlarged in diameter (23). I and the narrow portion (23) J are formed.

In the present invention other than the above embodiment, three or more locking rods of the fixing member may be provided.
