Is erected. The support column 13 is provided with a female screw hole 14 into which the set screw 4 is screwed from the opening 12 side. A step 15 is formed on the periphery of the opening 12.

The mounting members 2, 3 are fixed seats 21, 31, which are fastened and fixed to the connection end surfaces of the connected members A, B by screws 5.
And connecting portions 22 and 32 screwed to the fixing seats 21 and 31 and connected to the opening 12 of the relay member 1.

The fixed seats 21 and 31 are provided with base plates 212 and 312 which are formed by drilling countersunk screw holes 211 and 311 into which the screws 5 are inserted and which are in contact with the connection end surfaces of the connected members A and B, respectively, and a male outer shape. A flange 214 on which screw portions 213 and 313 are engraved,

The connecting portions 22 and 32 have fixed seats 21 and
Female screw part 2 screwed into the screw parts 213 and 313
21 and 321 are formed in a bowl shape engraved. Relatively large holes 222 and 322 are opened at the bowl-shaped tops of the connecting portions 22 and 32.

These relay members 1, mounting members 2, 3
Are connected by a spherical sliding structure 6 so that the angle can be adjusted.

The spherical sliding structure 6 includes a spherical seat 61 provided on the relay member 1 and connecting portions 22 and 32 of the mounting members 2 and 3.
And a spherical wall 62 provided at the bottom.

The spherical seat 61 is formed of a synthetic resin material such as polyacetal to prevent damage when the spherical wall 62 is formed of a metal material, and includes a spherical dish 611 and a spherical packing 612. The spherical plate 611 has a spherical bottom shape and is fitted to the support column 13 of the relay member 1 so that the spherical plate 611 is prevented from being pulled out by the set screw 4. The spherical packing 612 has an inner peripheral portion formed of a spherical ring shape, and is fitted into the opening 12 of the relay member 1.

As the spherical wall 62, the spherical surface around the holes 222, 322 of the connecting portions 22, 32 of the mounting members 2, 3 is used as it is.

In this construction, since the work is mainly performed by the contacting and screwing operations, the connecting work is easy. Naturally, the disassembly work is also easy.

Further, in the sliding of the spherical sliding structure 6, the operation is reliably and smoothly performed since the spherical wall 62 is sandwiched between the spherical seats 61 from both sides.

Note that, as shown in FIG.
-Shaped center axis of spherical sliding structure 6 (center of variable range)
Since a and b are set to other than 180 degrees, the variable range of the connection angle can be shifted in a specific direction.
Therefore, the holes 2 in the connecting portions 22 and 32 of the mounting members 2 and 3 are formed.
Even if the openings 22 and 322 are not very large, a sufficient variable range of the connection angle can be obtained on the shift direction side. If the diameters of the holes 222 and 322 are avoided in this way, a reduction in the contact area of the spherical sliding structure 6 is avoided, and the mounting strength of the spherical sliding structure 6 is maintained. Incidentally, as shown in FIG. 3, when the V-shaped angle c of the relay member 1 is 75 degrees, the connection minimum angle d is about 85 degrees and the connection maximum angle e is 1 degree.
It is preferable to set it to about 30 degrees.

In addition, as shown in FIG. 4, in the three-dimensional variation of the connection angle of the connected members A and B, in addition to the two-dimensional angles c and d shown in FIG. , B can be easily connected to form a step h in the arrangement direction.

FIG. 5 shows an embodiment (2) of a variable angle connector according to the present invention.

In this embodiment, the V-shaped angle c 'of the relay member 1 is set to 30 degrees.

According to this embodiment, the minimum connection angle d '
Is preferably about 125 degrees and the maximum connection angle e 'is about 170 degrees.

As described above, in addition to the illustrated embodiment, a configuration in which three or more attachment members 2 and 3 are connected to the relay member 1 is also possible.
