DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art For example, trees are artificially planted on sidewalks, roads, parks, and the like from the viewpoint of improving the cityscape and livability. Conventionally, as a means for planting such trees on the ground, a base formed by framing a plurality of pipe materials in a grid pattern is placed on the bottom of a planting hole cut out on 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 a fixed rod provided at the tip of the pipe material so as to be able to move back and forth in the axial direction is inserted into the vertical side of the planting hole to stabilize the tree after planting. (Japanese Unexamined Patent Publication No.
-219527).

[0003]

However, according to the above-mentioned prior art, since the base is assembled (the frame of the pipe material) at the site where the planting hole is provided, this operation is troublesome. Further, the opening area and the shape of the planting hole may be different between when there is a relatively large site area such as a sidewalk and a park, and when there is not enough room area such as a median strip. In such a case, when assembling the base (using the pipe material as a frame), it is necessary to adjust the planar size and shape, etc., and in some cases, it may be necessary to cut the pipe material. This, too, was a major factor complicating the work.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made in consideration of the above circumstances, and has a tree support capable of easily assembling a base without depending on a difference in an opening area and an opening shape of a planting hole. It is intended to provide a device.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the present invention includes a base mounted on a bottom surface of a planting hole cut out on the ground, and supports a tree rooted by a belt on a root pot W of the tree mounted on the base. A plurality of legs are protruded outward from the base so as to swing freely, and a grounding plate is provided at a protruding end of each leg. Body as opening degree setting means
It is characterized in that it is fixed so that the degree of opening between adjacent legs can be adjusted .

More specifically, according to the present invention , the base is provided with four legs that can swing freely via four fulcrum portions provided on the outer peripheral portion of the base at regular intervals. The grounding plate is provided at the protruding end of each leg, and the protruding ends of two adjacent legs and the protruding ends of two other legs are mutually connected. Coupling interval
They are connected to each other by connecting rods so that they can be adjusted .

In this case, a pair of legs connected by one connecting rod and a pair of legs connected by the other connecting rod.
Of the pairs of legs, the protruding ends of the legs that are adjacent to each other in each pair may be connected to each other by an open / close stabilizing bar at a variable interval. It is also desirable to provide a root escape hole at the center of the base for the reasons described below.

[0008]

[Function] The swing angle between the legs can be adjusted appropriately with respect to the base, and the adjusted mutual opening of the legs is fixed by an opening setting means (a connecting rod, an opening / closing stabilizing rod, etc.). Therefore, the contour (the size and shape) formed by connecting the protruding ends of the legs with imaginary lines can be adjusted to the opening area and opening shape of the planting hole.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a tree T according to a first embodiment of the present invention.
FIG. 1 shows a supporting device 1 of a ground 2
A base 5 placed on the bottom surface of the planting hole 3 cut into a hole, four legs 6 projecting outward from the base 5, and provided at the protruding end of each leg 6. Ground plate 7
And opening setting means for fixing the opening of each leg 6 (connection
(A bar, an open / close stabilizing bar, and the like) .

The base 5 is formed by pivotally connecting the roots of the legs 6 to four circumferential positions of a pair of upper and lower circular center plates 11 by means of bolts 12 and nuts 13. Is interposed between the upper and lower center plates 11. The center plate 11 is not limited to a circular plate, but may be a square plate such as a regular polygon. Legs 6
Is formed by a square pipe, and the bolt 12 used for assembling the base 5 as described above penetrates in a skewered manner at the base. Therefore, the bolt 12 can be swung with respect to the base 5 as a fulcrum 15.

Each of the legs 6 has a belt retaining ring 1 formed by bending a wire into a rectangular frame shape and connecting ends thereof by welding.
6 has been extrapolated. The ground plate 7 is formed by joining a circular plate to the lower surface of the protruding end of the leg 6 by welding or bolting. The grounding plate 7 is provided with an opening setting means (described later) at a position which is distributed with respect to the axis of the leg 6.
(Connecting rods, opening / closing stabilizing rods, etc.) Mounting bolts 18 and 19 used for mounting 10 are fixed by welding or the like in a state where the screw portions protrude upward. The ground plate 7 is not limited to a circular plate, but may be a square plate such as a regular polygon.

Mounting bolt 1 for each ground plate 7
The positioning of 8, 19 is such that the mounting bolts 18 or 19 used for the same purpose between adjacent ground plates 7 are close to each other. The opening degree setting means (such as a connecting rod and an open / close stabilizing rod) 10 includes a connecting rod 23 and an open / close stabilizing rod 24 attached to each leg 6.

The connecting rod 23 is cut into a predetermined length using an angle material (L-shaped steel) as a raw material, and a plurality of connecting rods 23 (each end portion in the drawing) are provided on one side near both ends at predetermined intervals along the longitudinal direction. 5 bolt insertion holes 25 are formed therethrough. Therefore, the connecting rod 23 selects an appropriate one of the bolt insertion holes 25 near each end, inserts the selected one into the mounting bolts 18 of the two adjacent ground plates 7, and connects them with the nut 26. It is used as it is. If the selection of the bolt insertion hole 25 is made different,
The distance between the ground plates 7, that is, the degree of opening between the legs 6 can be changed.

By providing a plurality of bolt insertion holes 25 in this way, the swing angle between the legs 6 can be adjusted stepwise, and there is an advantage that the adjustment can be performed easily and quickly. The opening / closing stabilizing bar 24 is cut into a predetermined length by using an angle material (L-shaped steel) as a raw material, and has a long hole 28 formed in one side near both ends thereof along the longitudinal direction.

Accordingly, the opening / closing stabilizing rod 24 is used in such a manner that the long holes 28 near each end are inserted into the mounting bolts 19 of the two adjacent ground plates 7 and connected by the nuts 29. Needless to say, the position of the mounting bolt 19 in the elongated hole 28 can be arbitrarily changed, whereby the distance between the ground plates 7, that is, the degree of opening between the legs 6 can be changed.

By providing such a long hole 28, it is possible to flexibly cope with the swing setting position of the leg 6 (which is governed by which bolt insertion hole 25 is selected in the connecting rod 23), and each member There is an advantage that the accuracy error of can be absorbed. In addition, there is an advantage that processing can be performed easily and at low cost as compared with a case where a plurality of bolt insertion holes are formed. Next, a case where the planting operation is performed using the support device 1 will be described.

In the following, for convenience of explanation, each leg 6 will be described.
Are distinguished into upper left, lower left, upper right, and lower right with respect to the positioning shown in FIG. First, the fulcrum 15 (nut 13) of all the legs 6 with respect to the base 5 and the joint (nut 29) of the open / close stabilizing bar 24 with each leg 6 are loosened to the extent that they do not come off. The connecting rod 23 is detached from each leg 6.

The swing angle of each leg 6 with respect to the base 5 is adjusted in accordance with the opening area and opening shape of the planting hole 3 cut out on the ground 2. FIG. 1 shows a case in which the site area is relatively large, such as a sidewalk or a park, and the outline formed by connecting the protruding ends of the legs 6 with a virtual line has a square shape. When there is no room in the site such as a median strip, a rectangular outline is formed as shown in FIG. 3, for example.

At this time, the upper left and lower left legs 6 and the upper right and lower right legs 6 are connected by the open / close stabilizing bar 24 via the grounding plate 7, and the protruding end portions are spaced from each other. It is restricted so as not to deviate from a predetermined range. That is, for example, a movement in which two specific leg bodies 6 adjacent to each other are in a parallel state or in a straight line is restricted. Therefore, the swing angle of each leg 6 can be easily and stably adjusted.

After the opening of each leg 6 is adjusted, the mounting bolts 18 of each ground plate 7 are connected to the connecting rod 23 for each of the upper left and upper right legs 6 and the lower left and lower right legs 6. The final correction is made to match the bolt insertion hole 25, and the connection rod 23 is connected (the nut 26 is tightened). afterwards,
A fulcrum 15 (nut 13) of the entire leg 6 with respect to the base 5,
Then, all the joints (nuts 29) of the opening / closing stabilizing bar 24 to each leg 6 are tightened to fix the opening of all the legs 6.

Next, the supporting device 1 is placed on the bottom of the planting hole 3, and the root pot W of the tree T is placed on the base 5, and the root 32 is inserted by the belt 32 inserted into the belt retaining ring 16. The pot W is tied to the base 5. Before the support device 1 is put into the planting hole 3, the root pot W of the tree T is tied on the base 5, and then the support device 1 and the tree T are planted together in the planting hole 3.
You may put it in.

Thereafter, the work is completed by backfilling the planting holes 3. 4 and 5 show a second embodiment of the present invention. This embodiment is different from the first embodiment in that a root escape hole is provided at the center of the base 5 in order to prevent the root vigor of the tree T from being hindered after planting due to the presence of the base 5. 33 is provided.

That is, after planting the tree T, the root pot W
The root extends from right below or to the side, but as shown in FIG. 2, the base 5 is located immediately below the root pot W at the time of planting. , The root from the mortar W cannot extend directly below. For this reason,
The root on the lower side of the mortar W is detoured to the side, and the detoured root may appear on the ground or cause a concrete structure on the ground to rise.

Therefore, in the present embodiment, as shown in FIGS. 4 and 5, a large escape hole 33 is formed concentrically with the center plate 11 forming the base 5 at the center of the center plate 11. The root is not hindered from extending right below, thereby preventing the root on the lower side of the root pot W from bypassing to the side. Also, if the escape hole 33 is formed to have a diameter slightly smaller than the root mortar W shown in FIG. 33, the root pot W is attached to the base 5.
It is easier to install on top.

The second embodiment is the same as the first embodiment except that the escape hole 33 is provided. Therefore, the other components are denoted by the same reference numerals as the first embodiment. The description is omitted. By the way, the present invention is not limited to the above embodiment. For example, the number of the legs 6 is not limited, and it is also possible to adopt a structure in which the fulcrum 15 of the swing is common to the plurality of legs 6.

Although the connecting rod 23 is provided with a plurality of bolt insertion holes 25 and the open / close stabilizing rod 24 is provided with the elongated hole 28, the plurality of bolt insertion holes 25 are provided only at one end of the connecting rod 23. It is possible to replace the long hole 28 with a plurality of bolt insertion holes only at one end of the opening / closing stabilizing bar 24, or to connect the connecting bar 23 and the opening / closing stabilizing bar 24.
It is also possible to make both of them long holes or a plurality of bolt insertion holes.

Further, an opening degree setting means (a connecting rod or an opening / closing stabilizing rod)
Etc.) The structure 10 is not limited to the structure using the connecting rod 23 or the opening / closing stabilizing rod 24, but may adopt a structure that prevents the swing of the leg 6 at the root side.

[0028]

The present invention is provided with the above-mentioned structure, in which the swing angle between the legs can be appropriately adjusted with respect to the base, and the angle after the adjustment is adjusted to the opening degree setting means (connection). Rods and open / close stabilizing bars).
The outline (the size and shape) formed by connecting the protruding ends of the legs with imaginary lines can be adjusted to the opening area and opening shape of the planting hole. Therefore, the base can be easily assembled without being affected by the difference in the opening area and the opening shape of the planting hole.

Further, when a root escape hole is provided in the center of the base, the root at the lower part of the mortar is allowed to extend directly below, and it is possible to prevent the root from diverting to the side. Roots can be prevented from appearing on the ground or lifting structures above the ground.
