[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree planting support for preventing a planted tree from tipping.

[0002]

2. Description of the Related Art Generally, when a tree is transplanted to a park, a street, or another place where greening is required, it is required to grow the tree until the roots of the tree have grown enough to support the above-ground portion after transplantation.
Since it takes about a year, at least during that period, the trunk was supported by supporting pillars such as a torii-shape.

[0003] However, the above-mentioned auxiliary strut requires a large-area installation surface around the tree, which hinders the passage of people and the like, and is inferior in appearance to natural trees in appearance. There are drawbacks.

As an improvement over the above-mentioned drawbacks of the conventional planting support, as shown in FIG. 4, an underground driving type pentagonal plate-shaped anchor 2 having no portion exposed above the ground is used.
At 0, there is a support for fixing the wire 25 and supporting the root pot 2.

When such a support is used, when a columnar planting hole 11 for accommodating the root pot 2 is formed,
The anchor 20 is hit into the bottom surface of the hole 11 by hitting with a hammer through a rod (not shown) with a hammer, and then the cable 20a connected to the anchor 20 is pulled up, and the anchor 20 is placed in a substantially horizontal state to increase the anchor effect and fix the anchor. . And
The belt 23 wound around the tree trunk and the anchor 20 were connected by a wire 25 via a block pulley 24, and the belt 23 was tensioned by a tensioning device 14 with a ratchet mechanism to support the root pot 2.

[0006]

However, in the conventional planting support described above, the soil A sandwiched between the anchor and the root mortar is compressed by the tension of the wire. The soil is likely to flow out at once when the shape retention property is deteriorated due to the penetration of rainwater or the like, and at this time, there is a problem that the wire is loosened and the tree is easily tilted.

On the other hand, as another cause of the loosening of the wire, when the root mortar becomes soft due to the rainwater, the shape of the upper peripheral edge of the root mortar is distorted, and the hung wire bites into the root mortar. . In order to cope with such a situation, maintenance work for periodically tensioning the wires after planting is required, and the economic burden increases accordingly. Furthermore, there is a problem that such a support cannot be used in a roof garden or the like where the anchor cannot be driven at a required depth.

Accordingly, the present invention solves the above-mentioned problems of the conventional planting support, which makes it difficult for the soil below the root pot to flow out, and the shape of the upper peripheral edge of the root pot is difficult to collapse, so that wires and the like are difficult to remove. Trees that can be used as a landscaping rooftop garden while maintaining the natural standing-tree atmosphere, even if the string-like member does not loosen and the soil below the supports slightly leaks out. The task is to use it as a support for planting.

[0009]

In order to solve the above-mentioned problems, in the present invention, radial arms supporting the bottom of the root pot of a tree to be planted project radially outward from the outer periphery of the root pot. A stabilizing plate to be slidable in the longitudinal direction of the arm, a support having a height reaching the upper periphery of the root pot is slidably provided in the arm in the longitudinal direction of the arm, The structure in which the string member for stopping was attached was adopted.

[0010] The tree planting support may be formed with a locking projection which can be inserted into the root pot in the middle of the column in the longitudinal direction.

[0011]

[Function] The tree planting support according to the present invention slides the stabilizer as long as possible from the radial arms arranged at the bottom of the planting hole, and applies it to a wide range of soil around the root pot. Lock and use. Then, when the column having a predetermined height is closely attached to the outer periphery of the root mortar with the root mortar placed on the arm, the string-shaped member bridged over the upper surface of the root mortar does not contact the upper peripheral edge of the root mortar. Or it can be locked on top of the strut so as not to cut into that part. For this reason, the shape of the upper peripheral edge of the supported mortar is unlikely to collapse, and the mortar is held upright from the surroundings by the columns. In addition, such a support is substantially stable even in relatively shallow soil, because the bottom area of the root mortar is substantially widened by the stabilizer and the soil fixing force is increased.
The stability is high even if the soil below the root pot sinks unevenly. Furthermore, since the soil is not interposed between the bottom of the root pot and the radial arm, the soil is not easily affected by the softening of the soil due to the penetration of rainwater, and the once-tensed string member does not relax.

[0012] When the pillar is provided with the locking projection, the root pot and the pillar are integrated, so that the tree to be planted becomes more difficult to tilt.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG.
Square members 4 slidably fitted into four groove-shaped radial arms 3 each having a bent top surface and supporting the bottom surface of root pot 2 of tree 1 to be planted are inserted. A rectangular stabilizer plate 5 is attached to the tip of the arm 3, and a pair of rectangular slide rings 6 is slidably mounted on the outer side of each arm 3, and a column 7 having a height reaching the upper peripheral edge 2 a of the root pot 2. Is fixed upright, and a U-shaped hook 9 for securing the string-shaped member 8 is attached to the upper part of the column 7, and further inserted into the inside of the root pot in the middle of the height of the column 7. Bar-shaped locking projection 1 to be obtained
0 is formed.

The radial arm 3 is formed by assembling and welding four ends of a rectangular channel steel having a certain length and joining them in a cross shape. The number of the arms 3 is, for example, about 3 to 6 arms. You can also.

As shown in FIG. 2, a rectangular plate-shaped stabilizer 5
When placed in the planting hole 11, it forms the same plane as the bottom surface of the root pot 2, and its corners are easily locked to the wall surface of the planting hole 11. Excellent. Of course, the shape of such a stabilizer may be various designs such as a triangle, a trapezoid, an ellipse, and a circle. The stabilizer 5 is attached to the lower surface of the square bar 4 by overlay welding, and can be shrunk by overlapping the lower surface of the radial arm 3. Therefore, almost the entire square bar 4 is accommodated in the arm 3. Therefore, it can handle even relatively small diameter root mortars. Also,
The dimensions of the arm 3, the timber 4 and the stabilizer 5 as described above are such that the tree after transplanting is in an upright state in consideration of the weight of the tree 1 to be planted, the height, the diameter of the root pot, and the tension of the branches. Is set to be stable.

The column 7 is fixed to a rectangular slide ring 6 which is slidable in the longitudinal direction of the arm 3 (in the direction of the arrow in FIG. 1). The slide ring 6 is arranged at a predetermined distance from the arm. It consists of one set. And
On the upper surface of the slide ring 6 located on the distal end side of the arm 3, a column 7 is fixed upright, and a wedge-shaped member 12 is fixedly connected across the lower part of the column 7 and the other slide ring 6. . As shown in FIG. 2, such a wedge-shaped member 12 supports the lower part of the root mortar 2 from the periphery when the column 7 approaches the outer periphery of the root mortar 2, so that the planted tree 1 can be relatively easily. It is useful for erecting.

The U-shaped hooks 9 attached to the upper portions of the columns 7 are fixed to the inner surfaces of the columns 7 facing each other. However, the hooks 9 may be mounted upright so as to straddle the upper end surfaces of the columns 7. Alternatively, if the leg 9a (see FIG. 1) of the hook 9 is rotatably attached to the side wall of the column 7, it can well cope with the pulling angle of the string member 8. As shown in FIG. 2, the hook 15 fixed to the outside of the column 7 locks a belt-like string-shaped member 13 wound around the outer periphery of the column 2 so as not to separate from the column 7 and the column 2.

The locking projection 10 is formed of a rod having a suitable thickness of about 3 to 10 cm, which can be inserted into the inside of the root bowl 2. This is inserted into the root mortar when the column 7 is arranged so as to be in close contact with the root mortar 2, and integrates the root mortar 2 and the column 7 very efficiently.

The string members 8 and 13 are made of a belt or a wire made of synthetic fibers or the like, as shown in FIG. A hook 9 is used to lock key points. At this time, the string-shaped member 8 is composed of one annular belt whose ring diameter is adjusted by a buckle 16 and another annular belt whose tension can be adjusted by interposing a well-known tensioning device 14 having a ratchet mechanism. Are linked to form a set, which is constituted by a total of two sets of annular belts.

To use the embodiment described above, first, FIG.
As shown in the figure, a planting hole 11 of an appropriate size is drilled in the root pot 2 of the tree 1 to be planted, and the support of the embodiment is arranged on the bottom surface thereof. Then, the radial arm 3 is extended to arrange the stabilizer 5 so as to be in contact with the hole wall, and is buried slightly in the hole wall as necessary. Next, the root mortar 2 is transplanted to the center of the radial arm 3, the support 7 is manually brought into close contact with the periphery thereof, and the locking projection 10 is inserted into the inside of the root mortar 2. It is tightened by a string-shaped member 13.

Then, as shown in FIG. 3, the string member 8 is hooked on the upper part of the column 7 and is hung over the upper surface of the root mortar 2 so as to surround the trunk, and the tension is adjusted by the tensioning member 14. . After that, it is sufficient to backfill the soil until the support is hidden.

[0023]

According to the present invention, as described above, since the stabilizers can be slid as much as possible from the radial arms arranged on the bottom of the planting hole and arranged in a wide range, the stability is extremely excellent. In addition, since the soil is not interposed between the bottom of the root mortar and the radial arm and there is no outflow of the soil, the string member once tightened does not relax. In addition, since the string-shaped member is locked to the upper portion of the support at a predetermined height so as to hardly contact the upper periphery of the root mortar, the shape of the upper periphery of the root mortar becomes difficult to collapse, and the string-shaped member is used for a long time. Difficult to relax.
Therefore, the necessity of maintenance work for periodically tensioning the string member is reduced, and it can be said that the present invention is extremely excellent in labor economy. Furthermore, since the support is not exposed to the ground, it does not impair the natural atmosphere of standing trees and can stably support trees even on hard soil that is difficult to excavate deeper than the guest soil. There is an advantage that it is also suitable.
