TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tree planting stabilizing device used to stably hold trees during tree planting.
[0002]
[Prior art]
Conventionally, when planting trees, a tree planting stabilizer is installed at the bottom of the excavated planting hole, and the root pot of the tree is placed on it, and the root pot is planted so that it can withstand strong winds etc. It has been practiced to tie to a stabilizer and then backfill the planting hole.
[0003]
Various types of such tree planting stabilizing devices are known. Usually, a root ring is placed on a metal arm formed with a framework, and a belt or the like is attached to a locking ring that is locked to the arm. The fastening strips are connected and wrapped around the shoulder of the root pot, thereby tying the root pot to the arm.
[0004]
In general, the locking ring is formed of a rectangular frame-shaped annular metal fitting that is externally inserted into the arm, and a fastening strip such as a belt is inserted through the annular metal fitting and hangs over the shoulder of the root bowl. It is fastened by a fastening means such as a winch, and the root pot is tied to the arm.
[0005]
[Problems to be solved by the invention]
In the case of the prior art, the arm is formed by a round pipe or a square pipe made of metal, and the locking ring is constituted by an annular fitting which is movably inserted outside the arm. Therefore, the annular metal fitting is freely movable in the longitudinal direction of the arm, so that it is easy to cope with the difference in the size and size of the root pot.
[0006]
Therefore, when the root mortar is tied to the arm, with the root mortar placed on the arm, the annular metal fitting is moved on the arm so as to come to a position corresponding to the size of the root mortar, and a tightening strip such as a belt is used. When the piece is inserted into the annular metal fitting and fastened at the upper part of the root pot, the annular metal fitting is pulled up by the tightening strip and is locked on the peripheral surface of the arm.
[0007]
However, when the fastening strip is fastened, not all of the annular fittings are necessarily fixed at a desired position in a desired posture with respect to the arm. That is, even if the annular bracket is displaced from a desired position with respect to the longitudinal direction of the arm or is in a twisted posture instead of an upright posture, when the annular bracket is pulled by fastening the fastening strip, The annular fitting is pressed against the arm and is temporarily fixed.
[0008]
However, in such a case, there is a risk that the annular metal fitting may move in the longitudinal direction of the arm after the tree planting, and if the annular metal fitting is slightly moved, the tightening strip that should have been bent is loosened. However, there is a problem that the tree planting stabilizer does not play its original role.
[0009]
[Means for Solving the Problems]
The present invention has been made in view of the above problems, and provides a tree planting stabilization device that solves the above-mentioned problems by forming an arm with a rigid long member in which nodes and grooves are alternately arranged.

At the top, a part of the fastening strip is provided with a fastening means capable of reducing the loop of the fastening strip, and a holding strip that stands up so as to hold the root pot is provided. With the fastening strip inserted and locked in the holding part, By reducing the loop of the fastening strip through the means, the holding strip is tightened, the holding portion of the holding strip is pressed against the surface of the root mortar, and the locking portion of the holding strip is engaged with the groove of the arm. It is configured to stop.
[0011]
Further, the present invention is configured as a second means, an arm is extended in a radial direction from a pedestal portion arranged at the bottom of the root pot of a tree, and the root pot is placed on the side from the bottom by a support member mounted on the arm. In the tree-planting stabilizing device, which is supported on the supporting member and a traction strip formed of a belt or the like connected to the supporting member is hung over the upper part of the root mortar and fastened, the arms are arranged with nodes and grooves alternately in the longitudinal direction. The supporting member is constituted by a pivotal portion that constitutes a rotation fulcrum movably disposed below the arm, and is deflected inward of the arm in the center direction with respect to the pivotal portion. A holding portion movably disposed above the arm, an undulating portion which is displaced outward in the direction of extension of the arm relative to the pivot portion and is disposed above the arm, and a portion near the undulating end of the undulating portion.
