BACKGROUND OF THE INVENTION The present invention relates to an agricultural and horticultural support joint.

[0002]

2. Description of the Related Art Conventionally, as an agricultural and horticultural support used for plant cultivation, for example, a steel pipe is coated with a synthetic resin layer, and the synthetic resin layer is provided with a plurality of projections along the length direction. Generally, it has been used as a single pillar of a predetermined length according to the use in advance.

[0003]

However, since such a conventional agricultural and horticultural support column has a predetermined length according to the use in advance, when a support column of various lengths is required for use, a plurality of types of lengths are prepared in advance. It was inconvenient because I had to prepare a stanchion. In addition, if it is desired to change the length of the supporting column, the entire supporting column must be replaced with another supporting column or the supporting column must be cut, which is a problem in terms of usability.

In view of the above situation, an object of the present invention is to provide a joint for agricultural and horticultural props by solving the above problems by connecting the props through a dedicated joint.

[0005]

A joint for an agricultural and horticultural strut according to the present invention has a substantially circular cross section, has a synthetic resin layer on at least the surface, and divides the synthetic resin layer substantially in the circumferential direction.
In this way, it is a joint of a pillar provided with a plurality of projections along the length direction, and it is made into a cylindrical body whose cross-section has a substantially circular shape, and the circumferential direction is divided into almost equal parts on the inner surface of the cylindrical body. A plurality of ribs along the length direction are provided corresponding to the protrusions of the column, and the inner diameter of the tubular body is almost equal to the outer diameter of the protrusion of the column.
When the rib is made, the protrusion degree is almost equal to that of the protrusion.
Made is, strut ends respectively inserted in the openings of both ends of the tubular body, the tubular inner surface is in close contact with the protruding top end of the tower, pile write the rising portion of the protrusion with the ribs apex is closely pillars surface It was designed to be pressed against each other.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 is a pillar, which is a conventional general-purpose agricultural and horticultural pillar. Generally, the pillar 1 has a surface of a core material 11 such as a steel pipe covered with a synthetic resin layer 12, and a terminal opening is watertightly treated. The synthetic resin layer 12 is provided with a plurality of projections 13 along the length direction of the support column 1. The protrusions 13 are generally provided along the length direction so as to divide the support 1 in the circumferential direction substantially equally.

The protrusions 13 are provided so that the rising portions along the length direction of the support column 1 are inclined in the circumferential direction of the support column 1, and even if they are provided continuously along the length direction of the support column 1. It may be provided discontinuously. Moreover, as shown in FIG.
The ridges having a mountain-shaped cross section along the length direction of the column 1 are pressed at equal intervals to form protrusions 13 in which concave portions 14 and convex portions 15 are alternately provided, and the concave portions 14 are arranged in the circumferential direction of the column 1. It may be slightly pushed out and slightly raised from the surface of the column 1.

Reference numeral 2 is a tubular body forming a joint, which is a synthetic resin such as polypropylene, polyethylene, polyvinyl chloride, ABS or nylon, or a mixture of these with a filler,
Alternatively, it is made of metal or the like. The tubular body 2 has a circular inner shape in cross section, and its inner diameter is substantially equal to the outer diameter of the protrusion 13 portion of the column 1. However, the inner diameters of the openings at both ends of the tubular body 2 are made slightly larger than the outer diameter of the projection 13 portion of the support column 1 so that the support column 1 can be easily inserted.

On the inner surface of the cylindrical body 2, a plurality of ribs 21 along the length direction are provided corresponding to the protrusions 13 of the support 1. Generally, a plurality of ribs 21 are provided so as to divide the circumferential direction of the tubular body 2 into substantially equal parts. The rib 21 has a protrusion degree substantially equal to the protrusion degree of the protrusion 13 of the column 1. Further, a partition wall 22 is provided in the circumferential direction in the substantially central portion of the inner surface of the tubular body 2, and serves as a stopper when the column 1 is inserted into the tubular body 2.

The tubular body 2 generally has an outer diameter of 4 to 10 of the column 1.
A double length is preferably used and formed into a straight cylindrical shape, but it may be formed into a bent cylindrical shape. Then, in order to connect the columns 1 to each other, the protrusions 13 of the columns 1 are positioned between the ribs 21 of the tubular body 2 as shown in FIG. 1A, and the columns 1 are placed in the end openings of the tubular body 2. insert. At this time, the inner surface of the tubular body 2 is brought into close contact with the tops of the protrusions 13 of the support 1, and the tops of the ribs 21 are brought into close contact with the surface of the support 1. Prop 1
When the cylindrical body 2 and the cylindrical body 2 are relatively rotated, the rotation is blocked by the protrusions 13 and the ribs 21 as shown in FIG.
Are pressed against each other so that the rising portions of the protrusions 13 do not fit into the rising portions, so that the support 1 and the tubular body 2 are fixed. The column 1 may be similarly inserted into the opening at the other end of the tubular body 2.

[0011]

As described in detail above, in the agricultural and horticultural support joint of the present invention, the inner surface of the tubular body is in close contact with the tops of the protrusions of the support, and the tops of the ribs of the inner surface of the tubular body are in close contact with the surface of the support and the protrusions are formed. since the rising portion bites manner is adapted to be pressed, to prevent backlash between the supports and fittings cheapest
Can be fixed firmly. Moreover, coupled with the fact that the ribs on the inner surface of the tubular body are provided so as to approximately equally divide the circumferential direction in correspondence with the protrusions of the column, the column is inserted into the tubular body,
The struts and joints can be fixed by a simple operation of rotating the ribs and projections until they hit each other , which improves workability .

Therefore, by connecting a plurality of columns via a joint as required, it is possible to obtain agricultural and horticultural columns of various lengths.
