Description

[Detailed explanation of the idea] The present invention relates to improvements in agricultural and horticultural supports.

Agricultural and horticultural supports made of iron or other metal wire coated with synthetic resin are already widely used as durable supports in place of bamboo, etc., but the known ones are based on the basic structure shown in Figure 3. Generally, a metal wire 10 having the same diameter from the end to the upper end is coated with a synthetic resin outer covering layer 20, and synthetic resin caps 30, 30 are attached to both ends.

However, as the length of this type of support increases, the center of gravity when erected also moves upwards, resulting in problems with its stability, and it is prone to being exposed to slight external forces or strong winds. It has the disadvantage that it tends to fall over when placed upright.

In addition, since the lower base end and the upper upper end have the same diameter, thin vines and branches that have grown from the tips of crops and flowers are less likely to get wrapped around them. It was not possible to bend it to fit along a branch, and there were also problems in terms of its adaptability to the crops being grown.

The purpose of the present invention is to easily eliminate such inconveniences that conventionally known agricultural and horticultural supports had, and to provide an agricultural and horticultural support that is improved in terms of both stability and adaptability. The gist is that a metal wire extending in a stepwise tapered shape from the base end toward the upper end is coated with a synthetic resin outer coating.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows one embodiment of the present invention, and FIG. 2 shows a modification thereof.

That is, the thing 3 shown in FIG. 1 is a metal wire 1 made of iron, aluminum, etc., which extends in a stepwise manner from the base end 1a toward the upper end 1b, and is inserted into the soil of a field or a pot, etc. It is coated with a synthetic resin outer layer 2 made of polyvinyl chloride, polyethylene, etc., and a synthetic resin cap body 4 is attached to the end of the proximal end 1a, and when used for home gardening etc. The base end 1a of the metal wire 1 is 5
The diameter is approximately 8 mm to 8 mm, and the upper end is 2.0 mm to 2.5 mm.
It is formed to have a length of about mmφ and a length of 0.3 to 1.5 m.

Such a metal wire 1 can be easily formed by a drawing process in which metal wires of the same diameter are stretched in stages while being heated. By widening or narrowing the tip of the die according to the conditions, an outer covering layer 2 made of a synthetic resin such as polyvinyl chloride or polyethylene is formed to manufacture the agricultural and horticultural support of the present invention. The covering layer may be a foam layer.

The agricultural and horticultural support 3 shown in FIG. 1 has support portions 11, 12, and 13 constituting each step tapering toward the upper end, and the support 3 shown in FIG. Constituent support columns 11, 12, 1
3 indicates that the diameter is the same in all parts.

In these embodiments, 4 and 4 are both caps attached to the base end 1a of the support 1, and as shown in FIG. A cap body is also fine.

The ones shown in the drawings are formed in such a way that they have three steps and the diameter becomes smaller as they move toward the tip, but this is not the only option. It's okay if it's something.

However, in addition to the embodiments shown in these examples, the agricultural and horticultural support of the present invention may have protruding nodes or protrusions on the outer covering of the synthetic resin. Not only is it effective in preventing strings from falling out when tying flowers to posts, but it is also effective in preventing them from falling out when multiple plants are tied together with string during transport. It is something like that.

Furthermore, although the metal wire 1 generally has a circular cross section, the agricultural and horticultural supports of the present invention are not limited to this cross-sectional shape, but can also adopt any shape such as a triangle, quadrangle, or pentagon.

When selecting these cross-sectional shapes, it is recommended that so-called angular shapes, such as triangles and squares, be chosen because they provide good soil support when buried in soil, etc., and provide stability during erection. It will be further improved.

As mentioned above, the agricultural and horticultural supports of the present invention are made of metal wires that extend in a stepwise manner from the base end toward the top end, and are coated with a synthetic resin coating, so that they can be installed upright in the soil or in a pot. In this case, the center of gravity of the strut is located on the heavy base side. Therefore, even if the length of the support column becomes large, the stability when erected is excellent.

In addition, since it becomes thinner towards the tip, it is easy to wrap around thin vines and branches that have grown from the tip of crops and flowers, and even if the tip of the branch has grown crooked, it is easy to bend the tip. Therefore, it can be easily bent to fit along vines and branches, and blends well with agricultural crops and flowers.

The agricultural and horticultural support support of the present invention is easy to manufacture because it uses a metal wire that tapers in a stepwise manner from the base end toward the upper end. In other words, there is a way to draw a metal wire into a tapered shape in a continuous manner, and obtaining such a continuous tapered shape requires advanced drawing technology, but there is a stepwise stretching method. To obtain a tapered shape,
A more sophisticated drawing technique is not required than in the continuous case.
