The strut connector a described in Patent Document 2 is provided on one side and, as shown in, for example, FIG. Alternatively, it was provided on one of the surface portions e.

When the connector main body b has an annular frame shape, the column introduction port j of the fitting recess g of the column clamping portion h has an annular frame shape as indicated by the arrows in FIGS. It was opened toward the front side in the extending direction of a connecting straight line n connecting the center k of the connector main body b1 and the center m of the fitting recess g. Further, when the connector main body b is linear, the support post introduction port j of the fitting recess g is perpendicular to the extending direction of the linear connector main body b2, as indicated by the arrow in FIG. 21(B). It was open in the direction of

FIGS. 20A, 20B, 21A, and 21B show a plant support device p configured using an annular frame-like connector main body b1 or a linear connector main body b2 having such a configuration. 20(A) and 21(A) are partial views for explanation, and in both of these plant support devices p (FIGS. 20A and 21A), the lower end side of each support f constituting the plant support device p is buried in the soil. It was assumed to be standing on the ground by

However, when the plant support device having such a configuration is set up on the ground, when a plant is supported by the plant support device, or when the plant is supported by the plant support device, the plant support device does not fit into the insertion recess g. There is a problem that an external force directed toward the support entry port j acts on the support post portion q in the mated state, and the support post portion q is likely to come off through the support entry port j. This point will be described below with an example.

(1) When the plant support device is erected on the ground by burying the lower end portion of each support f of the plant support device in the ground, if there is a hard portion such as gravel in the soil, When the lower end of the support hits the hard part, the support f is tilted outward (toward the support introduction port j in the open state of the fitting recess g), and as a result, fits into the fitting recess. There is a problem that the column portion q in the state is likely to come off through the column inlet j.

(2) In the cultivation of plants with strong springiness of branches, for example rose cultivation, when a branch is attracted to the support, the support portion q that is in a state of being fitted in the fitting recess g due to the springiness of the branch is the support. There is a problem that when pulled toward the introduction port j, the pillar portion q, which is fitted in the fitting recess g, is likely to come off through the pillar introduction port j.

(3) When vines bearing fruits such as cucumbers, bitter melons, and pumpkins are cultivated with the plant support device standing on the ground, the load of the fruits grown and heavy increases the specific load of the support connector a. The connector main body b is in a slanted state by concentrating on the fitting recess g. There is a problem that the portion q is easily detached through the pillar introduction port j.

(4) When vines bearing fruits such as cucumbers, bitter melons, and pumpkins are cultivated with the plant support device standing on the ground, the plant support device is used in a state where the leaves of the vines grow thickly and bear fruit. When exposed to a strong wind, the plant support device shakes greatly, and as a result, the support portion q, which is fitted in the fitting recess g, is likely to come off through the support introduction port j.

In the present embodiment, as shown in FIG. 2, four supporting column holding portions 9 are provided on the outer peripheral surface portion 6 of the connector main body 5 having an annular frame shape at an angular pitch of 90 degrees in the circumferential direction. It is In the present embodiment, the fitting recess 12 of each of the strut clamping portions 9 is opened toward the front side of an opening direction straight line 30 (FIG. 3), which will be described later.

The opening width of the post introduction port 15 is smaller than the diameter of the post 3 , and the post 3 is fitted into the fitting recess 12 by elastically widening the post introduction port 15 . In this embodiment, even if the connector main body 5 is turned upside down, the pillars 3 can be fitted into the fitting recesses 9 .

More specifically, the strut clamping portion 9 includes the first clamping piece 10 and the second clamping piece 11, as shown in FIG. As shown in FIG. 3, the second holding member 11 is provided integrally with the connector body 5 and has a guide piece 19 at its tip.

The first clamping piece 10 can be seen in the extending direction of the connecting straight line 16 that connects the main body center A1 (FIG. 2) of the connector main body 5 and the recess center A2 of the fitting recess 12, and the second clamping piece 10 , and a guide piece portion 19 is provided at the tip portion thereof. The first and second guide piece portions 19 and 19 are provided facing each other, and have inclined surfaces 21 and 21 in opposite directions so that the width between them expands toward the tip to form a V-shape. have. When the post 3 is fitted into the fitting recess 12 , the inclined surfaces 21 and 21 contact the peripheral surface 22 of the post 3 and guide the post 3 toward the fitting recess 12 .

The first and second clamping pieces 10 and 11 can form the fitting recess 12 into which the support 3 is fitted, and the support 3 guided as described above can be inserted into the fitting recess 12 . The fitting strut part 13 fitted into the fitting recess 12 is elastically clamped. The inner surfaces of the first clamping piece 10 and the second clamping piece 11 are formed into semi-circular surfaces 23 and 25, and the fitting recess 12 is formed by the semi-circular surfaces 23 and 25. there is Then, in a state where the post 3 is fitted into the fitting recess 12 as described above, the main body center A1 of the annular frame-shaped connector main body 5 and the recess center A2 of the fitting recess 12 are connected. The first clamping piece 10 arranged on the leading side in the extending direction of the connecting straight line 16 is attached to the supporting column outer peripheral surface portion 17 on the leading side in the extending direction of the fitting supporting column portion 13 fitted in the fitting recess 12 . , and as described above, the first clamping piece 10 supports the external force directed forward in the extension direction.

For this reason, in this embodiment, the center of the opening width of the post introduction port 15 is positioned on the opening direction straight line 30 passing through the recess center portion A2, and faces toward the extension direction of the opening direction straight line 30. are open to the public. The opening direction straight line 30 is inclined 20 to 25 degrees toward the main body center A1 side of the connecting straight line 16 with respect to an orthogonal straight line 26 passing through the recess center A2 and perpendicular to the connecting straight line 16 (Fig. 3) and a first straight line 27 that passes through the recess center A2 and is inclined 20 to 25 degrees toward the extension direction of the connecting straight line 16 with respect to the orthogonal straight line 26 (FIG. 3 is inclined by 25 degrees).

It should be noted that the shape of the connector main body 5 and the connector should be adjusted so that the fitting of the post 3 into the fitting recess 12 is not hindered even if the opening direction straight line 30 approaches the first straight line 27 . The arrangement state of the second clamping piece 11 with respect to the main body 5 is appropriately changed. For example, the shape of the connector main body 5 may be appropriately changed to a shape having a recess that can accommodate a part of the support 3, or a convex portion with a required projecting length to be connected to the connector main body 5 may be changed. It is modified such that the second holding piece 11 is arranged through the hole.

The support 3 has a length of 900 to 2100 mm, and a length suitable for cultivated plants is selected. The support 3 has a circular cross section and an outer diameter of, for example, 10 to 15 mm. The peripheral surface 22 (FIGS. 3 and 4) of the support 3 is formed as a smooth surface, and in addition, the peripheral surface 22 is provided with a plurality of discontinuous projection rows extending in the length direction. , the peripheral surface portion 22 may have unevenness.

FIG. 6 shows a contact state of the first clamping piece 10 against the outer peripheral surface 17 of the post when the straight line 30 in the opening direction coincides with the second straight line 29. The piece 10 can support an external force directed forward in the extension direction.

A work process for fitting the post 3 into the fitting recess 12 will be described with reference to FIGS. 3 to 5. FIG. The column 3 is in contact with both the inclined surfaces 21, 21, or one of the inclined surfaces 21 and the outer peripheral surface portion 6 of the connector main body 5, as indicated by the arrow in FIG. Then, by pressing with a finger toward the insertion recess 12 , the support post 3 can be fitted into the insertion recess 12 by elastically expanding the support introduction port 15 . In the upper part of FIG. 5, the post connector 2 is turned upside down, and the post 3 is fitted into the fitting recess 12 by elastically expanding the post introduction port 15 in the same manner as described above. Illustrated.

FIGS. 1, 4, and 5 illustrate a plant support device 1 comprising a cylindrical plant support frame 31 constructed using the post connector 2 having such a configuration. 1, it is constructed by using the three post connectors 2 , 2 , 2 and two arch-shaped posts 32 , 32 . The strut connectors 2 are arranged at the lower part, the upper part and the middle part of the arch-shaped strut 32, respectively. 3, 3, 3 required parts are inserted. The interval between the vertically adjacent strut connectors 2, 2 is set to 250 mm to 300 mm. Referring to FIG. 1, the column connector 2b located in the middle is upside down with the column connectors 2a, 2a located above and below. FIG. 5 is a partial perspective view showing a state in which the same strut 3 is fitted into the upper and lower fitting recesses 12b, 12a of the upper and lower strut connectors 2b, 2a which are in an inverted state.

FIG. 1 shows the cylindrical plant support frame 31 constructed by burying a 200 to 300 mm long portion of the lower end side 33 of the support 3 of the plant support device 1 having such a configuration in the ground. 1 shows a state in which the plant support device 1 is erected on the ground 35, and plants can be cultivated satisfactorily by the plant support device 1. FIG.

When the plant support device 1 having such a configuration is used, the conventional support connector, that is, the support inlet of the insertion recess extends outward in the extension direction of the connecting straight line of the connector main body having the shape of an annular frame. For example, when the plant support device 1 is erected on the ground 35 or when a plant is supported by the plant support device 1, as in the case of using a conventional post connector (FIG. 20) that is open toward the Alternatively, there is no possibility of causing the problem that the strut 3 is easily detached from the fitting recess 12 while the plant is being supported by the plant support device 1 .

This is because, as described above with reference to FIG. 3, the opening width of the support introduction port 15 of the support clamping portion 9 is formed to be smaller than the diameter of the support 3, and the connector main body 5 has an annular frame shape. The first clamping piece 10 arranged on the leading side in the extension direction of the connecting straight line 16 connecting the main body center A1 and the recess center A2 of the fitting recess 12 is fitted into the fitting recess 12 The first clamping piece 10 abuts against the outer peripheral surface portion 17 of the insertion support portion 13 on the front side in the extension direction, and supports the external force P acting on the support 3 toward the front side in the extension direction. This is because it is configured as

As a result, the external force P directed outward in the extending direction of the connecting straight line 16 of the fitting strut portion 13 (FIG. 3) that is fitted in the fitting recess 12 is applied to the first clamping piece 10 (FIG. 3). ), and the lateral external force toward the support inlet 15 is not so large.

In particular, as described above with reference to FIG. 5, when the column connector 2 is turned upside down and each column 3 is fitted into the fitting recess 12 through the column introduction port 15 in the same manner as described above. When looking at the same support 3, as shown in FIG. 5, the support 3 is supported by the arc-shaped bottoms 36b, 36a of the upper and lower insertion recesses 12b, 12a that open in the opposite direction in plan view. Therefore, in plan view, a restrained state is obtained in which the support 3 is surrounded in the circumferential direction by the upper and lower support support clamping portions 9b and 9a. Due to such restraining action, even if the external force P directed toward the support inlet 15 is large, the support 3 is effectively prevented from moving.

This point will be described below with an example.
(1) When the plant support device 1 is erected on the ground 35 by burying the lower end side 33 of each support 3 of the plant support device 1 in the ground

In this case, the lower end of the support 3 hits a hard part such as gravel in the ground, and the support 3 may be tilted outward (toward the first clamping piece 10). As a result, as shown by the arrow in FIG. 3, a large external force P directed outward, such as in the extending direction of the connecting straight line 16, acts on the fitting strut portion 13 that is fitted in the fitting recess 12. However, in this case, most of the external force P is supported by the first clamping piece 10, and the external force directed toward the post introduction port 15 does not act so much. As a result, it is possible to prevent the post 3 from coming off the fitting recess 12 through the post introduction port 15 . In particular, as shown in FIG. 5, when the connector main body 5 is turned upside down as described above, the support column 3 is arranged so that the fitting recesses 12b and 12a of the reverse openings arranged vertically in a plan view are Since it is restrained by the upper and lower strut clamping portions 9b and 9a, even if the external force directed toward the strut introduction port 15 is large, the restraint action prevents the strut 3 from coming off.

(2) Cultivation of plants whose branches have a strong springiness, for example, cultivation of roses, in which the branches are attracted to the support 3

In this case, due to the springiness of the branch, a large external force P (FIG. 3) directed outward, such as in the extending direction of the connecting straight line 16, acts on the fitting strut portion 13 that is fitted in the fitting recess 12. sometimes. In this case, most of the external force P is supported by the first clamping piece 10 (FIGS. 3 and 4), and the external force directed toward the post introduction port 15 does not act so much. As a result, it is possible to prevent the post 3 from coming off the fitting recess 12 through the post introduction port 15 . In addition, even when the springiness of the branch becomes stronger due to the growth of the branch after the attraction, the support 3 can be prevented from coming off the fitting recess 12 through the support introduction port 15 for the same reason. In particular, when the connector main body 5 is turned upside down as described above, the support 3 has upper and lower support holding portions having the above-mentioned insertion recesses 12b and 12a arranged vertically and open in the opposite direction in plan view. Since it is restrained by 9b and 9a, even if an external force directed toward the support introduction port 15 is large, the restraint action prevents the support from coming off.

(3) Cultivation of fruit-bearing vines such as cucumbers, bitter melons, and pumpkins with the plant support device standing on the ground

In this case, the load of the fruit, which has grown and become heavy, is concentrated on the specific support 3 of the support connector 2, and the support 3 is tilted outward. A large external force P directed outward may act on the column 3, but most of this external force P is supported by the first clamping piece 10 (FIGS. 3 and 4), and the column introduction port The external force toward 15 does not act so much. As a result, it is possible to prevent the post 3 from coming off the fitting recess 12 through the post introduction port 15 . Moreover, even when the springiness of the branch becomes stronger due to the growth of the branch after the attraction, it is possible to prevent the post 3 from coming off the fitting recess 12 . In particular, when the connector main body 5 is turned upside down as described above, the support 3 has upper and lower support holding portions having the above-mentioned insertion recesses 12b and 12a with opposite openings arranged vertically in a plan view. Since it is restrained by 10, 10, even if an external force directed toward the support introduction port 15 is large, the restraint action prevents the support 3 from coming off.

FIGS. 8 to 10 show a plant support device 1 constructed using a post connector 2 having such a configuration. The diameter of the struts 3 used in these plant support devices 1 is, for example, 10 to 15 mm. The support 3 has a length of 900 to 2100 mm, and a length suitable for cultivated plants is selected. Further, the center-to-center distance between adjacent struts 3, 3 is set to, for example, 150 to 250 mm, and the distance between vertically adjacent strut connectors 2, 2 is set to, for example, 250 to 300 mm. About 200 mm to 300 mm of the lower end side 33 of the support 3 is buried in the ground.
