This agricultural and horticultural support 1 is formed by attaching a support cap 3 shown in FIG. 5 to an upper end portion of a support member 2 shown in FIGS. As shown in FIGS. 3 and 4, the column member 2 is a cylindrical rod 21 formed by coating the surface of a steel pipe with a synthetic resin material, and has an annular shape that circulates in the vicinity of its upper end. A protrusion 22 is formed. In addition, a large number of protrusions 23 are formed on the circumferential surface of the support member 2 at intervals in the vertical direction. By forming the projections 23, the plant vines are firmly wound and do not slide down, and the clip does not slide down when the net N is fixed to the support member 2 with a clip or the like (not shown). Note that, as shown in FIG. 4, four rows of protrusions formed at intervals in the vertical direction are formed at intervals of 90 degrees. Furthermore, the lower end part of the support | pillar member 2 is made into the taper taper shape (conical shape) so that embedding to an underground is easy.

In addition, in place of the steel pipe, other metals such as aluminum alloy and stainless steel, or polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyamide, polyurethane, A tubular body made of a synthetic resin such as polyacrylonitrile, ABS, AAS, phenol resin, unsaturated polyester resin, epoxy resin, or FRP may be used. Moreover, as a synthetic resin material that coats the surface of the steel pipe, an α-olefin polymer such as polyethylene, polypropylene, polybutene, etc. may be used, or an ethylene-copolymerized α-olefin, or ethylene, It may be copolymerized with vinyl acetate, methacrylic acid or its ester, acrylic acid or its ester, etc. Furthermore, synthesis of polyethylene terephthalate, polybutylene terephthalate, ABS resin, AAS resin, urethane resin, polyamide resin, phenol resin, etc. Resins can be used, or these resins may be used in appropriate combination.

5 to 10 show the support cap 3 in this embodiment. As shown in FIG. 5, the column cap 3 includes a cap portion 31 for fitting on the upper end portion of the column member 2, and a holding portion 32 formed on the upper end of the cap portion 31 for holding the horizontal bar member 4. It has. The support cap 3 is integrally formed of a synthetic resin material. As the material, AAS resin, AES resin, polycarbonate, urethane resin, polyester, polyamide, or the like may be used alone, or these may be used. You may make it use combining suitably. As shown in FIGS. 6 to 10, the cap portion 31 has a substantially cylindrical insertion hole 311 that opens downward, and the upper end portion of the column member 2 is inserted into the insertion hole 311.

An annular ridge 22 can be fitted into the inner wall surface of the insertion hole 311 as a locking means 35 for locking the annular ridge 22 of the column member 2 when the column member 2 is inserted. A retaining hole 351 is formed in the circumferential direction. In this embodiment, the retaining hole 351 is a through-hole penetrating from the inner wall of the insertion hole 311 of the support cap 3 to the outer peripheral surface except for the four connecting pillars 313.

Similarly, a large number of retaining projections 352 are formed on the inner wall surface of the fitting hole 311 as locking means 35 for locking the annular protrusion 22 of the column member 2 when the column member 2 is inserted. ing. The retaining protrusion 352 protrudes from the inner wall surface of the insertion hole 311 so as to extend in the radial direction (inward direction), and is formed so that its height increases from the lower side to the upper side. The end surface 352a is flat and is connected to the retaining hole 351. As a result, as shown in FIG. 8, the side cross-sectional shape of the retaining protrusion 352 is a shape protruding in a triangular shape from the inner wall surface of the insertion hole 311. The diameter of a circle drawn by connecting the highest points of the retaining protrusion 352 is the minimum value of the inner diameter of the insertion hole 311.

The “height” of the retaining protrusion 352 refers to a length dimension in the radial direction from the inner peripheral surface of the fitting hole 311 of the support cap 3, and the retaining protrusion 352 having the maximum height. In the upper end portion, the inner diameter of the insertion hole 311 is the smallest. As shown in this embodiment, the maximum outer diameter of the column member 2 in the annular protrusion 22 portion of the column member 2 is made larger than the minimum inner diameter of the insertion hole 311 of the column cap 3, and the column cap 3 is preferably capable of being press-fitted into the three insertion holes.

That is, the minimum inner diameter of the insertion hole 311 is smaller than the maximum outer diameter of the protrusion 22 portion of the column member 2. Further, the support cap 3 is made of a synthetic resin material. When the support member 2 is press-fitted into the insertion hole 311 of the support cap 3, the retaining protrusion 352 is pushed by the annular protrusion 22 of the support member 2 to be inserted into the insertion hole 311. Retracts elastically in the radial direction (outward direction). When the annular protrusion 22 is fitted into the retaining hole 351 after press-fitting the supporting member 2, the retaining protrusion 352 presses the side peripheral surface of the supporting member 2 to return to the original state, Thereby, the support | pillar cap 3 is attached to the upper end part of the support | pillar member 2 stably. As shown in FIG. 11, in a state where the column cap 3 is fitted to the upper end portion of the column member 2, the annular protrusion 22 of the column member 2 is fitted into the retaining hole 351 of the column cap 3 and The lower portion of the protrusion 22 is placed and locked on the upper end of the retaining protrusion 352 so that the support cap 3 can be stably attached to the upper end of the support member 2. Yes. In this embodiment, a large number of retaining protrusions 352 are configured by forming four retaining protrusion groups 352 including five retaining protrusions 352 at appropriate intervals. In this manner, by arranging a plurality of retaining protrusion groups (preferably at three or more positions) at appropriate intervals, it becomes easy to insert the column member into the insertion hole 311.

Further, in this embodiment, a concave groove 316 extending in the vertical direction is formed on the inner surface of the fitting hole 311 of the connecting column 313 portion of the column cap 3 as shown in FIGS. 9 and 10. As shown in FIG. 12, the concave groove 316 is capable of inserting a large number of projections 23 formed in four rows in the longitudinal direction of the column member 2 of the column member 2 into the groove 316. The size of the tip of the groove is such that it contacts the bottom of the groove 316. That is, the inner diameter dimension of the fitting hole 311 passing through the bottom of the concave groove 316 and the outer diameter of the column member 2 passing through the tip of the protrusion 23 are substantially the same size. The attachment state when attached to the upper end of the is stable.

Furthermore, the support | pillar cap 3 is equipped with the holding | maintenance part 32 in the upper end. As shown in FIG. 1, the holding portion 32 is configured to hold the horizontal bar member 4 so as to pass the horizontal bar member 4 between the upper ends of the plurality of agricultural and horticultural supports 1. .

The holding part 32 in this embodiment includes holding pieces 321 that are opposed to each other and extend in an arc shape. That is, both holding pieces 321 draw an arc shape and extend in a direction away from each other as they go upward, and extend in a direction approaching each other from about the middle portion, and thus in a front view shown in FIG. The shape is such that a part of the upper end of the ring is cut out, and a circular space 37 is formed between the holding pieces 321.

The horizontal bar member 4 is lowered from above the holding portion 32 so as to be positioned in the space portion 37. In this embodiment, the two holding pieces 321 facing each other are arranged at the tips thereof. The receiving part 322 provided with the inclined surface 322a from which a mutual distance goes away as it goes is formed (refer FIGS. 5-7). As a result, the horizontal bar member 4 can be placed on the receiving portions 322, and therefore, the horizontal bar member 4 is easily guided to the space 37 of the holding unit 32, and the work of attaching the horizontal bar member 4 can be easily performed. .

Further, the distance between the tip portions of the holding pieces 321 is smaller than the outer diameter of the horizontal bar member 4 at the closest position. By adopting such a configuration, when the horizontal bar member 4 is press-fitted toward the space 37 from above, the front ends of both holding pieces 321 are elastically moved away from each other by being pushed by the horizontal bar member 4. When the horizontal bar member 4 has been press-fitted into the space 37, both holding pieces 321 are elastically pressed against the circumferential surface of the horizontal bar member 4 in an attempt to return to the original state. The member 4 is stably held by the holding portion 32.

Furthermore, in this embodiment, a plurality of protrusions 323 and 324 are formed on the inner peripheral surface of the holding piece 321 so as to protrude from the peripheral surface toward the inner side of the space portion 37. By doing in this way, since a horizontal bar member contacts and presses only in the projection part instead of the whole inner peripheral surface of the holding piece 321, it comes to be hold | maintained more stably at the holding part 32. FIG.
In addition, this holding | maintenance part 32 is not restricted to the above forms, According to the cross-sectional shape of the horizontal bar member 4, it is possible to apply the holding | maintenance part of various shapes.
