Description

[Technical Field]

[0001] The present invention relates to a horticultural support used in agriculture and horticulture, such as for growing vegetables and flowers. [Background technology]

[0002] Various proposals have been made for agricultural and horticultural supports used in agriculture and horticulture. Patent Document 1 discloses a rod for plant cultivation, which has a discontinuous row of projections provided on the outer surface of a rod in the lengthwise direction, and scale projections protruding from the outer surface of the rod positioned to the side of the discontinuous row of projections, the discontinuous row of projections being discontinuously protruding in the lengthwise direction of the rod to provide hooking protrusions for plant stems and vines, or to prevent the binding material from slipping off when plant stems are bound to the rod, and the scale projections protrude at regular intervals in the lengthwise direction of the rod from the smooth outer surface of the rod, with a gap provided between the scale projections and the discontinuous row of projections.

[0003] [Patent Document 1] Patent No. 4339343 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using the above-mentioned agricultural and horticultural support, the scale protrusions make it easy to align the binding position of binding materials such as attracting wires, but the protrusion positions of the discontinuous protrusion rows formed in multiple rows on the outer surface of the agricultural and horticultural support vary from row to row relative to the scale protrusions formed at specific positions, and when binding to the support using a binding material such as attracting string near the scale protrusions, the binding material is placed on the scale protrusions, so the protrusions cannot fully function to prevent the binding material from slipping off.

[0005] This problem can also be solved by controlling the formation positions of the discontinuous protrusion row and the scale protrusions so that they are not formed in the same horizontal position, but it is difficult to completely control the formation positions of the scale protrusions and discontinuous protrusions in the covering portion, which have different circumferential positions, formation pitches, and sizes.

[0006] To provide an agricultural and horticultural support pole which fully exhibits the function of preventing a binder used for binding plant stems and the like from slipping off and has a scale part serving as a mark for positioning. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention has the following configuration. In other words, the agricultural and horticultural support of the present invention is characterized in that raised portions are formed along the longitudinal direction at predetermined intervals and protrude in the thickness direction of the support, first protrusions are formed on the raised portions, and a number of second protrusions are formed in a row along the longitudinal direction on the outer surface of the covering layer excluding the raised portions.

[0008] The height of the raised portion may be greater than the height of the second protrusion.

[0009] The first projection may be formed so that the height of the first projection from the raised portion is greater than the height of the second projection from the covering portion.

[0010] The first protrusions may be formed in the same row as the second protrusions. [Effects of the Invention]

[0011] According to the agricultural and horticultural support of the present invention, the raised portions are formed at a predetermined interval, so that they fully function as a scale when aligning by binding, etc., and the positions at which they are formed are limited by the first protrusions on the raised portions and the second protrusions on the non-raised portions, so that regardless of the position, the first protrusions and the second protrusions are not formed concentrically, and when binding a lure string, etc., the first protrusions on the raised portions and the second protrusions on other portions fully function to prevent slipping, making it possible to prevent slipping.

[0012] Furthermore, according to the agricultural and horticultural supports of the present invention, when a frame material is created using multiple agricultural and horticultural supports, even when the raised portions are attached together in abutting relation to each other, the first protrusions formed on the raised portions enable stable attachment.

[0023] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is a front view showing one embodiment of an agricultural or horticultural support pole P according to the present invention. The structure of the agricultural and horticultural support P is not particularly limited, and it may be a rod-shaped pipe material 1 with a synthetic resin layer 2 coated on the outer surface thereof.

[0015] The agricultural and horticultural support P has raised portions 4 formed at predetermined intervals along the longitudinal direction, protruding in the thickness direction of the support, and first protrusions 41 are formed on the raised portions 4, and a large number of second protrusions 3 are formed in a row along the longitudinal direction on the outer surface excluding the raised portions. The positions where the raised portions 4, first protrusions 41, and second protrusions 3 are formed are not particularly limited as long as they are formed on the outer surface of the agricultural and horticultural support P, and they may be formed on the synthetic resin layer 2 covering the outer surface of the pipe material 1.

[0016] Furthermore, in the embodiment of the present invention, the first protrusions 41 and the second protrusions 3 are formed in the same row, but this is not limited to this, and the first protrusions 41 may be formed at a different position from the second protrusion row in the circumferential direction of the covering portion, as long as they are on the raised portion 4.

[0017] In the agricultural and horticultural support P of the present invention, the positions at which the first protrusions 41 and the second protrusions 3 are formed are limited and they are not formed aligned on the same circumference, so that when binding, binding can be performed without placing a binder on the protrusions, and therefore the slippage prevention function can be fully exerted without controlling the protrusion formation positions.

[0018] The pipe member 1 is a tubular body made of metal such as iron, stainless steel, or aluminum alloy, or synthetic resin such as polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyamide, polyurethane, polyacrylonitrile, ABS, AAS, phenolic resin, unsaturated polyester resin, epoxy resin, or FRP, and its cross-sectional shape is not particularly limited, but may be circular, elliptical, polygonal, or the like, but as shown in this embodiment, a tube having a true circular cross-section is preferably used.

[0019] Furthermore, the synthetic resin material that covers the outer surface of the pipe material 1 may be a polymer of an α-olefin such as polyethylene, polypropylene, or polybutene, or may be a copolymer of ethylene with an α-olefin, or a copolymer of ethylene with vinyl acetate, methacrylic acid or its ester, acrylic acid or its ester, or the like. Furthermore, synthetic resins such as polyethylene terephthalate, polybutylene terephthalate, ABS resin, AAS resin, urethane resin, polyamide resin, or phenol resin may also be used, or these resins may be used in appropriate combination.

[0020] 2 and 3 are partially enlarged front and side views of the raised portion 4 of the agricultural and horticultural support P according to the present invention, in which the first protrusions 41 are formed in the same row as the second protrusions 3 and are formed in a shape that follows the raised portion 4. Furthermore, the first protrusions 41 formed at the boundary of the raised portion 4 are formed with an inclination that follows the raised portion 4. This allows the first protrusions 41 to fully perform their role of preventing slippage when binding the binder K to the raised portion 4.

[0021] 4 and 5 are cross-sectional views taken along lines AA and BB in Fig. 2, respectively, and show that the synthetic resin layer 2 of the raised portion 4 is raised in the circumferential direction from the synthetic resin layer 2 of the non-raised portion, and is formed in close contact with the pipe member 1. The protruding height h2 of the raised portion 4 is also formed to be higher than the protruding height h1 of the second projections 3. This improves the visibility of the raised portion 4, allowing it to fully function as a marker when aligning the bonding position.

[0022] The cross-sectional shape of the raised portion 4 is not particularly limited to circular, elliptical, etc., but as shown in this embodiment, a cross-section having a perfect circle is preferable because it can provide visibility regardless of how the agricultural and horticultural support P is set up.

[0023] Fig. 6 is a partially enlarged cross-sectional view of the cross section taken along line CC in Fig. 3. The protrusion height h3 of the first protrusions 41 is formed to be higher than the protrusion height h1 of the second protrusions 3. This allows the protrusions 4 to serve as markers, and when binding a binder to the protrusions 4, they can exhibit a stronger slippage prevention function than non-protrusions.

[0024] Furthermore, the formation width l2 of the raised portion is wider than the formation width l3 of the first protrusions, and is also wider than the width l1 including the formation width and formation interval of the second protrusions, so that even when the first protrusions and the second protrusions are formed in the same row, one or more first protrusions can be formed on the raised portion.

[0025] Figure 7 shows an example of an agricultural or horticultural support P according to the present invention in which a binder is attached. The two agricultural or horticultural supports P are aligned using the raised portions 4, and then the binder is attached. The raised portions 4 make alignment easy, and because the first projections 41 are formed in the same row as the second projections 3, the second projections 3 and the first projections 41 do not interfere with each other, and the agricultural or horticultural support P can be attached at any position while fully exhibiting its anti-slip function.

[0026] In this embodiment, the agricultural and horticultural support P has a length of approximately 1800 mm and an outer diameter of approximately 16 mm, and the raised portions 4 are formed every 300 mm, but are not limited to this size. [Explanation of symbols]
