Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root pot fixing device used for a device for supporting trees to be planted in parks, streets, roofs of buildings and the like.

[0002]

2. Description of the Related Art A conventional tree supporting device is a park or a street where a hole is dug in the ground, an anchor member for anchoring a root pot is fixed around the hole, and the root pot is inserted into the hole. Wires are wrapped around the top and side surfaces of the root pot, and by anchoring this wire to the anchor member for anchoring the root pot around the hole, the root pot is fixed and the fall of trees is prevented,
They are backfilling the soil and planting trees. Also, in artificial ground locations such as the roof of a building, a pedestal member is installed in place of the anchor member for anchoring the root pot, the root pot is placed on this, and wires are wrapped around the top and side surfaces of this root pot, By anchoring the wire to the pedestal member, the root pot is fixed to prevent the trees from collapsing, and embankment is planted around the root pot to plant trees. These tree support devices are disclosed in, for example, Japanese Patent Laid-Open No. 62-19522.
No. 5, JP-A No. 5-260862, and the like.

[0003]

The conventional tree supporting device uses a wire as a root pot fixing means,
When using the wire in this way, the anchoring member or pedestal member for anchoring the root pot installed around the planting position is used as the anchoring point, and the wire is wrapped around the top and side surfaces of the root pot and tightened. Although I am using it, it is unavoidable that the wire is accompanied by elongation, and it is difficult to tighten the circumference of the root bowl evenly due to this elongation, it is easy to become uneven, and while correcting this Since it is necessary to proceed with the work, the fixing work is complicated, and the wire is often overstressed, which damages the root pot and tightens the root of the tree too much, which may hinder the growth and growth of the tree after planting. there were.

The present invention has been proposed in view of the above problems of the conventional root pot fixing means, and an object of the present invention is to make the root pot fixing work easy and quick,
Moreover, it is an object of the present invention to provide a root pot fixing device for a tree supporting device that does not damage the root pot and the root of the tree.

[0005]

In order to achieve the above object, the present invention forms a polygonal frame that is larger than the outer circumference of the root of a tree and smaller than the outer circumference of a root pot with a chain,
A root-pot fixing tool for a tree supporting device in which one end of an anchor member for anchoring a root-pot or a anchor member for a pedestal member is connected to each corner of the polygonal frame.

The polygonal frame may be a quadrilateral frame such as a rhombus or a square.

[0007]

[Function] The chain has almost no elongation as compared with the wire, and the chain links alternately bite into the root pot in a 90 ° standing / falling form, and there is no slip like wire, so this chain is used for trees. By forming a polygonal frame that is larger than the outer circumference of the root and smaller than the outer circumference of the root pot, the upper surface of the root pot can be pressed accurately and reliably without tightening the root of the tree, and, The other end of each tether is connected to each corner of this polygonal frame by connecting one end of the tether to the root pot anchoring member or the pedestal member. By anchoring to the root pot, the root pot can be anchored from the direction of each corner of the polygonal frame and securely fixed.

When the polygonal frame is a quadrangular frame, the shapes of the root of the tree and the outer periphery of the root pot are anchored from four directions, so that the tree can be stably supported with a relatively small number of members.

FIG. 1 is a plan view showing an embodiment of a root pot fixing device according to the present invention, FIG. 2 is a schematic side view showing a first use example of the root pot fixing device according to the present invention, and FIG. It is a schematic side view which shows the 2nd example of use of the root bowl fixture which concerns on.

As shown in FIG. 1, the root pot fixing device of the present invention has a chain 1 in which both ends 1a and 1b of a chain 1 are connected by a connector 2a which can be opened and closed, and is folded in two. The other ends, that is, the midpoint 1c of one chain 1 and the points 1d and 1e having a length half that of the chain 1, are connected with the couplers 2b, 2c and 2d, respectively, and these couplers 2a and 2b , 2c and 2d, the tethers 3a, 3b, 3c,
Connect one end of 3d. This tether 3a, 3b, 3
If the other ends of c and 3d are pulled in all directions, the chain 1 becomes a rhombic or square frame shape. Tether 3a, 3b, 3
In the present embodiment, a chain is used as c and 3d, but a wire or other strip may be used.

The length of the diagonal line of the diamond-shaped or square frame thus formed is set to be larger than the outer circumference of the root of the tree 4 and smaller than the outer circumference of the root pot 5. Further, each of the tethers 3a, 3b, 3c, 3d has the other end connected with the couplers 6a, 6b, 6c, 6d, and the couplers 6a, 6b, 6c, 6d are shown in FIG.
Then, the tightening device 8 such as a turnbuckle is used for tightening and anchoring, or the anchor member 9 for anchoring the root bowl shown in FIG. 3 is tightened and anchored by using the tightening device 8 such as a turnbuckle. This tightening tool 8 includes a pedestal member 7 or an anchor member 9 for anchoring a root bowl.
A bolt 8a connected to the bolt 8a, a locking sleeve 8b loosely fitted to the bolt 8a, and a nut 8c. A locking ring 8b 'is integrally attached to the locking sleeve 8b.
Each of the tethers 3a, 3b, 3c, 3d is attached to the locking ring 8b '.
The other ends of the tethers 3 are connected by the connectors 6a, 6b, 6c, 6d, and the nut 8c is tightened in this state.
A, 3b, 3c and 3d are tightened and anchored. The coupler 2
a, 2b, 2c, 2d and couplers 6a, 6b, 6c, 6
d has the same structure, and its structure is C
A screw joint is used in which the opening of the mold ring is closed by a screw sleeve so as to be openable and closable. Chain 1
A metal link chain called a heavy link coated with anticorrosive paint is used. In FIG. 1, reference numeral 10 indicates a pad for protecting the corner portion of the root pot 5 from the chain 1, and 3e indicates a preliminary tether.

In the above-mentioned embodiment, the tree 4 is placed on the upper surface of the root pot 5.
One chain 1 is wound around the root of the, and both ends thereof are connected to form a chain ring, and the tethers 3a, 3b, 3c, 3d
In the example, the case of forming a rhombus or a square by expanding it in four directions is illustrated. However, in forming the rhombus or a square, two chains may be used, and a plurality of chains such as four chains may be used. May be used. In addition, not limited to a rhombus or a square, when the shape of the root pot 5 is distorted, it is an appropriate polygonal frame shape according to the shape of the root pot 5, such as a pentagon, a hexagon, etc., and a tether is provided at each corner. It is to be attached.

[0013]

According to the present invention, the upper surface of the root pot can be accurately and surely pressed into a polygonal frame shape without tightening the root of the tree, and the anchoring strips at each corner of the polygonal frame are provided. By anchoring the other end of the body to the anchor member or the base member for anchoring the root pot, the root pot can be securely fixed. Therefore, the work of fixing the root pot can be performed easily and quickly, and there is no fear of damaging the root pot and the root of the tree.

If the polygonal frame is a quadrangular frame, a tree can be stably supported with a relatively small number of members.
