BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree supporting device.

[0002]

2. Description of the Related Art For example, trees are artificially planted on pavements, roads, parks and the like from the viewpoint of improving the cityscape and habitability. Conventionally, as a means for planting such trees on the ground, a base made of a grid of pipes is placed on the bottom of the planting hole cut into the ground, and placed on the center of the upper surface of the base. The root pot of the placed tree is tied to the base with a belt, and the fixed rod provided at the tip of the pipe material that can be retracted in the axial direction is pierced on the vertical side of the planting hole to stabilize the tree after planting. There are some (see Japanese Patent Laid-Open No. 2-219527).

[0003]

However, according to the above-mentioned conventional technique, since the fixing rod is provided so as to be able to move in and out from the pipe material in the axial direction, the fixing rod can be pierced into the vertical side surface of the planting hole. The hammer had to be shaken sideways to drive in the fixed rod, which was a very heavy task.

Further, if there is a large stone in the ground at the place of driving, the fixed rod cannot be driven, so that the desired strength may not be obtained. In view of such circumstances, it is an object of the present invention to provide a tree supporting device which can support a tree firmly by a simple work by reducing the construction work in the planting hole as much as possible.

[0005]

[Means for Solving the Problems] In order to achieve the above object,
The present invention has taken the following technical means. That is, the invention according to claim 1 is provided with a base placed on the bottom surface of the planting hole cut into the ground, and the root pot of the tree placed on the center of the upper surface of the base is tied to the base with a belt. In the tree supporting apparatus described above, a swing arm whose tip end is pushed up to the vertical side surface of the planting hole in a tilted state is pivotally attached to the upper surface of the end portion of the base in a vertically rotatable manner. To do.

Further, in addition to the above-mentioned structure, the invention according to claim 2 is further provided with an earth pushing plate fixed to the tip of the swing arm so as to be pierced obliquely from above from the vertical side surface of the planting hole when the arm is rotated downward. It is characterized by being

[0007]

The swing arm provided on the upper surface of the end of the base is rotatable up and down, and the tip of the swing arm is struck by the hammer or the like from above to the vertical surface of the planting hole. Therefore, the swing arm acts as a bracing member that receives an axial compressive force at the corner portion of the planting hole, and fixes the base to the bottom surface of the planting hole.

On the other hand, when the earth pushing plate is provided at the tip of the swing arm, the earth pressure applied to the earth pushing plate is transmitted to the base through the swing arm, thereby further stabilizing the base.

[0009]

An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 4, the tree supporting device adopted in the present embodiment has a base 3 placed on the bottom surface of a planting hole 2 cut into the ground 1, and a vertical rotation on an upper surface of an end portion of the base 3. And a plurality of swing arms 4 that are freely pivoted.

The base 3 is formed by connecting four leg members 6 made of die steel having a C-shaped cross section in a cross shape in plan view.
The opening side of the cross section is the upper surface side of the base 3, and the ground plate 7 is welded to the lower surface of the tip of each leg member 6.
A laterally long engagement hole 9 is formed in each side wall 8 of each leg member 6.
Are provided at regular intervals in the longitudinal direction of the tree, and one of the engaging holes 9 is provided with a root pot 10 of a tree at the center of the upper surface of the base 3.
A hook 12 for the belt 11 is provided for binding. The latch 12 is formed by bending a metal rod in a U shape, and inserts the left and right free ends, which are oppositely bent outward, into the engaging hole 9 from the inside of the cross section of the leg member 6. so,
The leg member 6 is swingably attached.

A mounting member 13 for pivotally mounting the swing arm 4 on the upper surface of the base 3 is provided at the tip of each leg member 6. In this embodiment, the mounting member 13 is used as the base. It is configured separately from 3. That is, the mounting member 13 includes a rectangular cylindrical slider 14 slidable within the cross section of the leg member 6 and a pair of mounting brackets 15 facing each other fixed to the upper surface of the slider 14. Bracket 1
5 is arranged so that the facing direction thereof faces the cross-sectional width direction of the slider 14.

A pair of thumbscrews 16 are screwed onto the outer surface of the end portion of the side wall 8 of the leg member 6, and the mounting member is fitted from the front end opening of the leg member 6 toward the center 17 of the base 3. Thirteen
The slider 14 is fixed to the leg member 6 by tightening the thumbscrew 16. Therefore, by loosening the thumbscrew 16 and moving the slider 14 in the longitudinal direction of the leg member 6, the pivoting position of the swing arm 4 can be changed.

The swing arm 4 is made of steel square bar,
A lateral pin 18 oriented in the width direction of the leg member 6 is inserted through a base end portion of the swing arm 4 arranged between the mounting brackets 15. Therefore, as shown in FIGS. 3 and 4, the swing arm 4 is pivotally attached to the tip end portion of each leg member 6 so as to be vertically rotatable so that the longitudinal direction thereof is along the longitudinal direction of the leg member 6. .

At the tip of the swing arm 6, the earth pushing plate 1 is attached.
9 is fixed. The earth pushing plate 19 is made of a steel plate material having a tapered blade portion 20 at the lower end edge, and one surface of the upper end portion is welded substantially perpendicularly to the axis of the swing arm 6. As a result, when the swing arm 4 rotates downward, the blade portion 20 of the earth pushing plate 19 causes the blade surface 20 of the planting hole 2 to rise.
It will be pierced from diagonally above.

Next, a work procedure for carrying out a planting work using the above supporting device will be described. First, the base 3 is placed on the ground 1 approximately at the center of the bottom surface of the planted hole 2, and the slider 14 of the mounting member 13 is attached to the tip of each leg member 6 of the base 3.
Is fitted and fixed with a thumbscrew 16 to attach the swing arm 4 to each leg member 6. Then, the root pot 10 of the tree is placed in the center of the base 3, and the belt 1 inserted into the hook 12 is inserted.
At 1, the root pot 10 is bound on the base 3.

When the tip end of each swing arm 4 is tapped from above with a hammer or the like to push the earth pushing plate 19 into the soil obliquely, the tip end of the swing arm 4 stands up with a planting hole in an inclined state. The base 3 is pushed to the side surface, whereby the base 3 is pressed against the bottom surface. After setting the base 3 in the planting hole 2 in this manner, the work is completed by backfilling the planting hole 2.

In the above-mentioned planting method, the swing arm 4 is first attached to the base 3 and then the base 3 is planted in the hole 2.
It may be set inside. On the contrary, the root bowl 10
The rocking arm 4 may be attached to the base 3 after being set on the base 3. In such a case, the rocking arm 4 does not get in the way when the root bowl 10 is placed and work is performed. Cheap.

The present invention is not limited to the above supporting device. For example, the number of leg members 6 is not limited to four, and when the ground plate 7 is provided, it is sufficient to have two or more, and two or more leg members 6 are radially arranged to form the base 3
Should be configured. Further, the swing arm 4 need not be provided corresponding to all the leg members 6, and the number thereof is not limited to four. Further, the swing arm 4 may be pivotally attached to the mounting bracket 15 directly fixed to the base 3.

[0019]

As described above, according to the present invention,
Just hit the swinging arm from above with a hammer etc., and the swinging arm that acts as a bracing member can firmly fix the base to the bottom of the planting hole, so it is necessary to drive the fixing rod deeply in the lateral direction as in the past. It is possible to firmly support the tree with no work.

According to the second aspect of the invention, the earth pressure applied to the earth pushing plate is transmitted to the base side, so that the base can be more stabilized.
