Description

The present invention relates to a plant cultivation shelf, a rod member that constitutes the plant cultivation shelf, and a regulation cap and a regulation cylinder that constitute the rod member.

As examples of plant cultivation racks in which bar members are joined to each other via joining members, those disclosed in Patent Documents 1, 2, 3, and 4 have been proposed.

The plant cultivation racks according to Patent Documents 1 and 2 have two pillars each having a joint member provided at the upper end thereof, which are erected on the ground at a required interval, and the adjacent joint members support horizontal bar members. A post frame is formed by holding both end portions in a detachable and elastically sandwiched state, and a net material is hung on the post frame. It was designed to grow together.

In addition, the plant cultivation racks according to Patent Documents 3 and 4 use a plurality of opening/closing type columns in which a joint member is provided at the upper ends of a pair of left and right columns that are connected so that they can be opened and closed at the upper ends. The opening and closing pillars that are open in a mountain shape are erected on the ground with a required interval, and the adjacent joint members hold both ends of the horizontal bar in a detachable and elastically sandwiched state to form a pillar frame. A net material is hung on both inclined outer surfaces of the support frame, and the vines planted in the ridge are made to grow on the net material.

By the way, the joint member used to construct these plant cultivation racks has a C-shaped holding portion provided with a holding groove having a narrow upper open end. Then, the both ends of the horizontal bar member are accommodated in the holding grooves by elastically widening the upper end open portion, and the both ends of the horizontal bar member are elastically held. The strut frame is configured by connecting the struts and the openable struts to each other through the .

Therefore, when vines such as cucumbers, bitter melons, and pumpkins are cultivated on the plant cultivation shelf, if the plant cultivation shelf is exposed to strong wind in a state where the leaves of the vines grow thickly and bear fruit, the plant cultivation can be difficult. The shelf swings horizontally (swings in the extension direction of the horizontal bar). As a result, there is a risk that the soil around the support-embedded portion buried in the ground will be spread out and a gap will be created, causing the support to wobble and the plant cultivation shelf to collapse. In addition, when the lateral movement of the plant cultivation rack becomes large, a phenomenon occurs in which the axis of the horizontal bar is greatly inclined with respect to the axis of the holding groove, and as a result, the upper end opening opens and the holding is carried out. There is also a possibility that the plant cultivation shelf may be damaged due to the detachment of the portion from the horizontal bar. Furthermore, when the plant cultivation racks are swayed by strong winds, the trunks, stems, branches and leaves of the cultivated plants are broken, and the fruits are damaged by rubbing against the net material, causing damage to the plants. There was also a problem of giving
