Description

[Detailed description of the invention] This invention buries a longitudinal buried frame with a cover plate that can be opened and closed under the ground surface, and separately supports the undulating pillar in a undulating column support frame that can freely rotate up and down, and the undulating column support frame The tree was fitted onto the end of the longitudinal burial frame to form an undulating pillar, so that the tree could be stored upright by undulating against the longitudinal burial frame.

In particular, this invention removably fixes the fixed circumferential flange and receiving flange that protrude laterally from the upper ends of both sides of both the undulating column support frame and the longitudinal embedding frame, so that the undulating column can be buried in the longitudinal direction when bent. This invention relates to a fence post that rises and falls from the ground, making it possible to replace only the undulating pillar with a new one while leaving the frame as it is buried, and facilitating the replacement of damaged undulating pillars.

Next, one embodiment of this invention shown in the drawings will be described. 1 is a hollow undulating column 1' which has a retractable handhold fitting 10 into which a rope or the like can be inserted at the upper end and serves as a handhold during undulating. However, a long hole 13 is bored in the lower end root portion 12 in parallel with the longitudinal direction of the undulating column 1.

A pivot 5 passes through this.

Both ends of the pivot 5 are fixed to both side walls of an undulating column support frame 7 having a gutter-shaped cross section, and fixing flanges 8, 8 are respectively provided laterally protruding from the upper ends of both sides of the undulating column support frame 7. , 8 has rivet holes 9', 9
' is provided.

Separately, the longitudinal burial frame 3 buried below the ground surface GL has a bridge shape and has an open opening 2 at the top, and receiving flanges 18, 18 are protruded laterally at the upper ends of both sides of the longitudinal length. A cover plate 4 covering the opening 2 is hinged to one side of the cover plate 4 with a hinge 6, and end plates 20 and 20' are fixed to both ends.

The undulating column support frame 7 is thus fitted onto the end of the longitudinal buried frame 3, the fixed circumferential collar 8 rests on the receiving collar 18, and the fixed screws 9.1
The undulating column 1 is connected to the longitudinal buried frame 3 by inserting the rivet holes 9', 9' into the screw holes 9'' of the receiving flange 18.

Reference numeral 14 designates a chino that is fixed to the lower part of a handhold fitting 10 provided at the upper end of the undulating column 1 so as to be freely retractable, and is built into the undulating column 1 so as to hang down therein.

Since this idea is configured as described above, the undulating column 1
When not in use, it is sufficient to fold it down around the pivot 5, store it in the longitudinal buried frame 3, and cover it with the cover plate 4.

Next, when using the undulating column 1, open the cover plate 4, move the undulating column 1 somewhat to the right as shown in FIG. The undulating pillar 1 can be easily erected by holding the undulating pillar 1 itself as a handhold and raising it.

If you let go of the undulating pillar 1, the undulating pillar 1 will be located at the pivot 5 and the long hole 13.
Guided by this, it descends slightly and stabilizes its position.

In addition, to ensure the stable standing of the undulating column 1, close the cover plate 4.
It is held by the end plate 20, but in this embodiment, a rotation stopper a' is carefully provided.

In particular, according to this invention, the undulating column support frame 7 is placed within the longitudinal buried frame 3.
In addition, the fixed peripheral flanges 8, 8 of the undulating column support frame 7 are fitted.
Although the receiving flanges 18, 18 of the longitudinal burial frame 3 overlap and are fixedly connected to each other in a detachable manner, the undulating column 1 to the longitudinal burial frame 3
If the retention of the rice is smooth, the retention of the rice is certain.

If the undulating column 1 is bent or otherwise damaged and needs to be replaced, the longitudinal embedding frame 3 and the undulating column support frame 7 are removably fixedly connected, so the longitudinal embedding frame 3 can be left in the buried state. Then, only the undulating column support frame 7 with the undulating column 1 is installed in the longitudinal buried frame 3.
All you have to do is remove it and replace it with a new undulating column support frame 7 with a new undulating column 1 attached.

In this case, since the fixed connection between the frames 7 and 3 is the part of the longitudinal buried frame 3 exposed above the ground, the frames 7 and 3 can be attached and detached very easily.

In this way, the longitudinal burial frame 3 can be reused without being removed from below the ground surface GL, thereby eliminating waste of equipment.
