DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural and horticultural support, and more particularly, to an agricultural and horticultural support suitable for supporting growing plants.

[0002]

2. Description of the Related Art Conventionally, in addition to bamboo, knotted metal tubes or resin-coated metal tubes have been used for agricultural and horticultural supports. It is fixed by using a tying device such as a cord and formed into a mountain shape, or a horizontal member is hung over an appropriate position of a column standing in parallel and fixed using a tying device such as a string to form a lattice. By doing so, they support growing plants.

[0003] In this case, the nodes of the agricultural and horticultural supports not only support the supports but also improve the entanglement of the growing plants and prevent the plants from sliding off when the supports are fixed to the supports using a binding device such as a string. It had a function to prevent it.

[0004]

In conventional agricultural and horticultural supports, the nodes are formed at equal intervals in the longitudinal direction of the supports. Even if the pillar is installed so that the first node is located near the ground surface, it takes a long time to reach the next node from the first node, so it is possible to improve the entanglement of growing plants. In some cases, the function of the node of preventing slipping when the plant is fixed to the support using a tying tool such as a string cannot be sufficiently exhibited.

The present invention has been made in view of the above-mentioned problems of the conventional agricultural and horticultural supports, in order to improve the entanglement of the growing plants even in the case of small seedlings having a low growth rate, or to tie the plants to the supports using a stringing device such as a string. It is an object of the present invention to provide an agricultural and horticultural support that can sufficiently exhibit the function of a node that prevents slipping when fixing using a method.

[0006]

Means for Solving the Problems To achieve the above object, an agricultural and horticultural support according to the present invention is an agricultural and horticultural support in which a coating layer made of a thermoplastic resin is formed on a metal tube. The node is characterized in that the longitudinal direction of the knot is formed so as to gradually increase from one end to the other end of the column. In this case, an arbitrary enlargement method is adopted such that the intervals in the longitudinal direction of the nodes are formed so as to be sequentially enlarged for each node, and for example, the nodes are formed so as to be sequentially enlarged for a plurality of nodes. be able to.

[0007] In this agricultural and horticultural support, a band-like or dotted chain-like node is formed so that the longitudinal interval thereof is gradually increased from one end of the support to the other end, so that the support is provided from the lower end of the support. By setting up the pillars so that the intervals in the longitudinal direction gradually increase toward the upper end, it takes a long time to reach the next node from the first node, even for small seedlings that have a low growth rate. Without, it is possible to make the entanglement of the growing plants good, and to fully demonstrate the function of the node of preventing the plant from sliding down when fixing the plant to the support using a tying device such as a string, From the upper end of the support to the lower end,
By installing the struts so that the intervals in the longitudinal direction gradually increase, it is possible to easily bind and fix a suspension line for branch suspension or the like on the upper portion of the support, and the suspension line may shift downward. Can be more reliably supported by the node immediately below. Further, compared to the case where the nodes are formed evenly at a narrow interval, the amount of the thermoplastic resin constituting the nodes can be reduced.

In this case, water-tight caps can be provided at both ends of the column.

Accordingly, it is possible to prevent the metal pipe such as a steel pipe from being rusted due to rainwater or water sprinkling in the hollow portion of the pole, and to improve the durability of the pole.

[0010] The coating layer and / or the cap may be made of a polyolefin resin.

As a result, there is no adverse effect of environmental hormones when the agricultural and horticultural support is used and when it is disposed after use.
In addition, no harmful substances such as chlorine gas are generated even when incinerated.

Further, a knurl pattern can be formed on the coating layer.

[0013] Thereby, the entanglement of the plant can be further improved.

The coating layer and / or the cap may contain at least one of a fungicide, an insect repellent coloring agent and an insect repellent.

[0015] This makes it possible to selectively impart fungicidal and insect repellency to the agricultural and horticultural supports.

Further, the surface shape near the base of the node with respect to the column can be formed such that the upper surface is nearly horizontal when the column is erected.

As a result, the function of catching the knots is improved, the support of the object to be supported such as a plant or a string is ensured, and the downward sliding can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an agricultural and horticultural support according to an embodiment of the present invention.

1 and 2 show an embodiment of an agricultural and horticultural support according to the present invention. The agricultural and horticultural support 1 is formed by forming a coating layer 4 made of a thermoplastic resin on the surface of a metal tube 2 via an adhesive layer 3 as necessary. The caps 51 and 52 are provided, and the band-like node 6 is moved from one end (the lower end in the present embodiment) of the column 1 to the other end (the upper end in the present embodiment).
The longitudinal interval L is formed so as to gradually increase.

In this case, the cap 51 provided at the lower end of the column 1 has a convex shape with a conical pointed tip in order to reduce the resistance when the column 1 is inserted into the ground. And a cap 5 disposed at the upper end of the column 1
No. 2 uses the one whose tip is formed flat, respectively. By arranging the water-tight caps 51 and 52 on both ends of the column 1 in this way, it is possible to prevent rainwater or water spray from entering the hollow portion of the column 1 and rust the metal tube 2 such as a steel tube. The durability of the column 1 can be improved.

The node 6 is formed by partially changing the thickness of the coating layer 4.
For example, the first node 61 is provided above 100 to 700 mm (L0), and the interval L in the longitudinal direction is sequentially increased from the position toward the upper end, that is, L1 <L2 <
Sections 62 and 6 are set so that L3 <L4 <L5 <L6 <.
3, 64, 65, 66, 67,... In this case, the method of expanding the interval L is not particularly limited. For example, as shown in Table 1, the interval L is regularly expanded by a certain distance (in the example of Table 1, 5 mm). , It is desirable to be configured to enlarge at a fixed ratio.

[0022]

[Table 1]

In Table 1, the numerical value of the first node is the distance L0 from the lower end of the column 1 to the first node, and the numerical value in parentheses is the distance from the lower end of the column 1 to the upper node. The other numerical values indicate the distance between the node and the node immediately below the node.

Further, nodes 61, 62, and 62, which are formed so as to gradually increase the interval in the longitudinal direction toward the upper end of the column 1,
In addition to 63, 64, 65, 66, 67,..., Auxiliary nodes 65a serving as marks can be formed at appropriate intervals (in the present embodiment, as shown in FIG. The node 65a is formed adjacent to the fifth node 65.) Thus, for example, a horizontal member (not shown) is provided between the columns 1 standing in parallel with the auxiliary node 65a as a mark. , The level can be easily adjusted.

In this embodiment, the distance between the nodes 6 in the longitudinal direction is set to one of the nodes 61, 62, 63, 64, 6.
5, 66, 67,... Are formed so as to be sequentially enlarged. However, the present invention is not limited to this. , L1 = L2 <L3 = L4 <L5 = L6 <... (Every two), L1 = L2 = L3 <L4 = L5 = L6 <. In addition to forming
The number of nodes is changed so as to be sequentially enlarged, that is, the interval L in the longitudinal direction is L1 = L2 <L3 <L4 = L5 <L6 <.
. (Every other and two), L1 = L2 = L3 <L4 <L5 = L6
= ... (every third and every other), an arbitrary enlargement method such as forming the node 6 can be adopted. You can also.

The shape of the surface of the joint 6 near the base with respect to the column 1 is set so that the upper surface is nearly horizontal when the column 1 is erected, specifically, the angle between the upper surface 6a of the node 6 and the horizontal plane. By forming the nodes 6 so that θ is 20 ° or less, preferably 10 ° or less, and more preferably 5 ° or less, the function of catching the nodes 6 is improved, and the supporting object such as a plant or a string is supported. Can be reliably supported, and downward sliding can be prevented. In addition, this kind of agricultural and horticultural support 1
As described above, it is formed by continuously extruding the coating layer 4 made of a thermoplastic resin on the surface of the metal tube 2 via the adhesive layer 3 as necessary. The node 6 is formed by sliding the mold back and forth in the extrusion direction. The shape of the joint 6 can be easily changed by adjusting the sliding motion before and after in the extrusion direction of the mold.

In this embodiment, the band-shaped node 6 has been described. However, the shape of the node is not limited to this. For example, as shown in FIG. . And also in this case, the joints 71, 72,
73, 74, 75, 76,...

As described above, the band-shaped or chain-shaped nodes 6, 7
Is formed so that the longitudinal distance L thereof is gradually increased from one end of the support 1 to the other end, so that, for example, as shown in FIG. From the first clause 71 (61), the next clause 72 (62)
It does not require long days to reach the plant, improves the entanglement of the growing plant, and prevents the plant 9 from slipping down when the plant 9 is fixed to the support 1 using a tying tool 8 such as a string. , 7 functions can be fully exhibited, and the interval between nodes 6 and 7 is widened on the upper part where the growth rate is fast, so the amount of thermoplastic resin constituting nodes 6 and 7 is reduced. Can be done.

In this case, the plant to which the strut 1 is applied is a small seedling, a plant with low independence such as tomato or cucumber, or a vine with no independence such as green beans or morning glory. Although the example in which the column 1 is installed so that the interval L in the longitudinal direction is sequentially enlarged from the lower end to the upper end of the column 1 has been described, the type of the plant to which the column 1 is applied (eg, eggplant, pepper, fig, etc.) Depending on the method of using the strut 1 (for example, hanging a tree plant in the snow), the strut 1 may be directed from the upper end to the lower end of the strut, although it may be self-supporting, but may be a plant that suspends branches to support the fruit weight. The column 1 can be installed so that the interval L in the direction is sequentially increased. As a result, the number of the nodes 6 and 7 at the top of the column 1 is large, and the interval L is small. Easily tie suspension lines for branch suspension, etc. It is possible to constant, hanging line even if the shift down, and that can be reliably supported by the sections 6 and 7 immediately below.

As the thermoplastic resin forming the coating layer 4 and the resin material forming the caps 51 and 52, a thermoplastic resin such as a vinyl chloride resin can be used. It is preferable to use a polyolefin resin. As a result, there is no adverse effect of environmental hormones when the agricultural and horticultural supports are used and when disposed after use, and no harmful substances such as chlorine gas are generated even when incinerated.

In addition, as shown in FIG. 4, in the coating layer 4, by partially changing the thickness of the coating layer 4, an uneven knurled pattern 41 can be formed as shown in FIG. . The knurl pattern 41 extends in the longitudinal direction of the support 1,
In addition to being formed parallel to the central axis, it can be formed in a spiral shape. Thereby, the entanglement of the plant can be further improved.

The thermoplastic resin for forming the coating layer 4 and the resin material for forming the caps 51 and 52 include at least one of a fungicide, an insect repellent coloring agent and an insect repellent on at least the surface layer thereof. It can be contained. This makes it possible to selectively impart fungicidal properties and insect repellent properties to the agricultural and horticultural supports, which can be suitably used for cultivation of fruits and vegetables without pesticides.

[0033]

According to the column for agricultural and horticultural use of the present invention, the band-like or chain-like node is formed so that the longitudinal interval thereof is gradually increased from one end to the other end of the column. For,
From the lower end to the upper end of the strut, by installing the strut so that the interval in the longitudinal direction gradually increases, even for small seedlings with a slow growth rate, from the first node to the next node It does not require long days, it can make the entanglement of growing plants good, and it can fully demonstrate the function of the node that prevents sliding when fixing the plant to the support using a tying device such as a string. On the other hand, from the upper end to the lower end of the support, by installing the support so that the longitudinal interval thereof is gradually increased, it is possible to easily bind and fix a suspension line for branch suspension or the like to the upper part of the support. Therefore, even if the suspension line is displaced downward, it can be reliably supported by the node immediately below the suspension line. Further, compared to the case where the nodes are formed evenly at a narrow interval, the amount of the thermoplastic resin constituting the nodes can be reduced. This makes it possible to obtain easy-to-use agricultural and horticultural supports at low cost.

Further, by providing water-tight caps at both ends of the column, it is possible to prevent rain or sprinkling water from entering the hollow portion of the column and to rust a metal pipe such as a steel pipe, thereby improving the durability of the column. be able to.

Further, by forming the coating layer and / or the cap from a polyolefin resin, there is no adverse effect of environmental hormones when the agricultural and horticultural support is used and when it is disposed after use. No generation of harmful substances such as chlorine gas.

By forming a knurl pattern on the coating layer, the entanglement of plants can be further improved.

In addition, by adding at least one of a fungicide, an insect repellent coloring agent and an insect repellent to the coating layer and / or the cap, the fungicide and the insect repellent are selected for the agricultural and horticultural support. Can be provided.

Further, the surface shape near the base of the node with respect to the column is formed such that the upper surface becomes nearly horizontal when the column is erected, thereby improving the function of catching the node.
It is possible to reliably support a support object such as a plant and a string, and to prevent downward sliding.
