DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment (one embodiment) of a stand structure for hydroponic cultivation comprising a standing angle-adjustable column according to the present invention and a standing angle-adjustable column will be described with reference to the drawings. I do.

The upright-angle-adjustable column 1 of the present embodiment is shown in FIG.
As shown in FIG. 3, a base 10 for mounting on an installation surface G such as the ground, a bolt 23 screwed to a nut 22 fixed to a lower end of a long pipe 21 are provided. It comprises a column bolt 20 having a shelf mounting plate 24 in its part, and fixing means 30 for fixing the column bolt 20 to the base 10.

The base 10 has a cone-shaped main body 11.
And a dome-shaped support plate 12 provided integrally with the upper part of the main body 11, and a bolt insertion hole 13 penetrating through the top of the support plate 12.
Two trapezoidal windows 14 are provided on the side surface of the base 10. In addition, the window portion 14 may be appropriately provided at only one place.

A bolt 23 at the lower end of the column bolt 20 is loosely inserted into the bolt insertion hole 13 in the base 10, and nuts 31 and 32 constituting the fixing means 30 are provided.
The column bolts 20 are fixed to the support plate 12 by tightening. The window 14 is used to insert a spanner or the like to fix the lower nut 32 disposed in the base 10 when the nut 31 is rotated.

The fixing means 30 is provided with a washer 33 having a curved surface which is formed in a curved shape conforming to a substantially spherical curved surface of the support plate 12. The washer 33 having the curved surface and a normal disk-shaped washer 33 are provided. The support plate 12 is sandwiched between a washer 34 and two bolts 31 and 32.

In this embodiment, as the fixing means 30 disposed on the concave curved surface side of the support plate 12 (below the support plate 12), an elongated hole 35 having an elongated hole 35 is used. It comprises an annular member 36 and a cylindrical washer 37 disposed further below the annular member 36. In the present embodiment, both ends of the annular member 36 are curved, so that a large number of contact portions with the concave curved surface of the support plate 12 can be secured.

The bolt 23 at the lower end of the column bolt 20 is inserted into a slot-like insertion groove 35 provided in the annular member 36, and the column bolt 23 extends along the longitudinal direction of the insertion groove 35. The lower end (bolt 23) of 20 is movable. Therefore, the adjustment of the standing angle of the column bolt 20 is facilitated. Furthermore, since the annular member 36 and the curved surface of the support plate 12 surely contact at two or more points, a large frictional force between the annular member 36 and the support plate 12 is always ensured.

Further, the cylindrical washer 37 serves to adjust the angle of engagement of the nut 32 disposed on the lower side with the frustoconical side portion. That is, the support bolt 20
Even when the lower end portion (bolt 23) is not orthogonal to the annular member 36, the cylindrical washer 37 and the side surface of the nut 32 engage with each other at a certain free angle,
It is possible to reliably obtain a strong and stable tightening state of the annular member 36 by the nut 32.

On the other hand, as described above, a substantially triangular plate-like shelf-mounting plate 24 is fixed to the end (upper end) of the column bolt 20 substantially perpendicular to the column bolt 20. The two guide portions 25 erected in a direction substantially perpendicular to the upper surface of the shelf material mounting plate 24 and a shelf material passing portion 26 formed by cutting out the intersection of the two guide portions 25 are provided. Is provided.

Therefore, by disposing the (usually bar-shaped) shelves 2 in the shelves passing portion 26 so as to be orthogonal to each other,
The shelf 2 can be securely held on the shelf placing plate 24. Furthermore, the shelf 2 can be easily and reliably orthogonalized by aligning the shelf 2 along the inside of the two guide portions 25 on the shelf mounting plate 24.

By arranging the plurality of upright-angle-adjustable columns 1 configured as described above at appropriate positions, an embodiment of a shelf structure 3 for hydroponics according to the present invention as shown in FIG. Can be provided.

When using the upright-angle-adjustable column 1 constructed as described above, first, the base 10 is placed on an installation surface G such as the ground, and a nut 22 at the lower end of the pipe 21 is placed.
The height of the plurality of columns 1 is adjusted by changing the screw position with the bolt 23. At this time, it is preferable that the directions of the shelf mounting plates 24 at the upper ends of the plurality of columns 1 are aligned in the same direction so that the shelf 2 can be arranged so as to be orthogonal to each other.

If the support column 1 cannot be erected at the desired angle due to unevenness or inclination of the installation surface, the nut 31
Or, loosen 32 and adjust the angle of the column 1. Here, since the support plate 12 and the washer 33 are formed in a spherical shape, the standing direction of the pipe 21 can be freely changed to the direction of A or B in FIG. 1 by loosening the nut 31 or 32. If the nut 31 or 32 is tightened at the optimum angle, the standing angle of the column 1 can be easily and reliably adjusted and set.

Next, the shelves 2 are inserted into the shelves passing portion 26 of the shelves placing plate 24 of the column 1, and
By aligning the shelves 2 along the inner surface of the device, a plurality of shelves 2 can be easily and reliably arranged and fixed at correct positions and angles.

Therefore, by using the column 1 of the present invention, the hydroponic cultivation shelf structure 3 which requires considerable care to be surely installed in a horizontal state can be extremely easily and stably. Can be installed.

The present invention is not limited to the above embodiment. As shown in FIG. 5, the main body 11 of the base 10 may be cylindrical, or the window 14 may be omitted. As shown in FIG. 7, the main body 11 of the base 10 may be provided with a plurality of legs 15.

In the case where a plurality of legs 15 are provided as shown in FIG.
1 to fix the nut 32.

The present invention also relates to the base 1 according to the present embodiment.
The support plate 12 may be a spherical support plate 12 that is convex downward as shown in FIGS. 7 and 8. In this case, the support plate 1
The bolt insertion hole 13 may be provided in the center of the bottom of the second 2, and the spherical washer 33 may be used upside down.

Further, without departing from the scope of the present invention, a spherical washer 33 may be used above and below the support plate 12 to clamp the support plate 12,
The nut 31 may be omitted, and the spherical washer 33 or the support plate 12 may be directly fixed by the nut 22 of the column 1.

In addition, without departing from the spirit of the present invention,
The shape, the arrangement angle and the number of the two guide portions erected in a direction substantially perpendicular to the upper surface of the shelf mounting plate are changed, and the hydroponic is performed by using a plate as the shelf. You may implement so that the shelf structure for cultivation may be installed. In this case, it is not necessary to provide a shelf material passage between the two guides.

Further, the fixing means may be implemented by omitting the spherical washer 33 or the annular member 36, or may be used as a support column in which the bolt 23 is fixed directly to the lower end of the pipe 21 by welding, The configuration, dimensions, mounting position, mounting method, material, etc. of each part such as the support bolt and the fixing means may be appropriately changed and implemented.
