Description

  The present invention relates to a fixed planting plate member for plant cultivation, and more particularly, to a fixed planting plate member that can change between plants.

When growing multiple plants, in order to make effective use of the growing space, arrange the plants at a narrow interval at the seed stage, and replant the plants at a large interval from the seedling stage. The method of changing the interval according to the size of the plant body is common.
However, if the plant body is dug up for the replanting work, the root may be damaged, and manpower is necessary.
On the other hand, plant factories are attracting attention as a place for employment of disabled people. However, in practice, there are many operations that are performed with the arms raised and bending the hips, which may be a burdensome task especially for wheelchair users.
Therefore, Patent Document 1 proposes a fixed planting plate member that can be changed between plant strains without changing the plant body by changing the interval between the parts on which the plant body is placed.

Specifically, the fixed planting plate member described in Patent Document 1 has a mountain-folded member that expands and contracts between stocks. This stretchable member is arranged continuously in the horizontal direction and refracted into a V shape and formed into a mountain fold shape, and intermittently arranged in the vertical direction and refracted into a V shape into a mountain fold shape. It is comprised from the member formed in this, It is comprised so that expansion-contraction in the vertical direction and a horizontal direction is possible.
Further, when the elastic members adjacent in the lateral direction are contracted, they are formed to have different heights alternately. For this reason, when contracting in the vertical direction, mutual interference between the elastic members adjacent in the horizontal direction is avoided.

JP 2012-223120 A

However, in the fixed planting plate member described in Patent Document 1, when the expansion and contraction member is contracted in the lateral direction, they interfere with each other due to the thickness of the expansion and contraction member in the vicinity of the bending start point of the expansion and contraction member adjacent in the lateral direction. There was a thing. For this reason, the jig | tool which avoids this mutual interference by shifting so that the elastic member adjacent to a horizontal direction may not overlap was required.
Therefore, there has been a demand for a fixed planting plate member that does not interfere with each other without using a jig and can be smoothly changed between a folded state and an extended state.
An object of the present invention is to solve the above-described problems, and an object thereof is to provide a fixed planting plate member that can be smoothly expanded and contracted between a folded state and an extended state.

  According to the present invention, according to the present invention, the plate pieces for planting plants are arranged in two directions orthogonal to each other, and the distance between the plate pieces is adjusted in the two directions by changing between a folded state and an extended state. A fixed planting plate member that can be arranged, and includes a plurality of plate piece units in which the plate pieces are arranged in one of the two directions, arranged in the other direction of the two directions. , Among the plurality of plate piece units, interposed between the plate piece of the first unit and the plate piece of the second unit located next to the first unit in the other direction, When adjusting the distance in the one direction, interposed between the first bending member that is mountain-folded when adjusting the distance in the direction and the plate piece arranged in the one direction in the first unit Mountain fold And a third bending member that is interposed between the plate pieces arranged in the one direction in the second unit and that is mountain-folded when adjusting the distance in the one direction. The distance between the plate pieces adjacent in the one direction in the first unit is shorter than the distance between the plate pieces adjacent in the one direction in the second unit, and the third bending member is The second folding member disposed next to the second folding member in the other direction, and having two standing walls that rise in the folded state, and a connecting portion that connects the two standing walls in the one direction, When the third folding member is folded in the one direction in the folded state, the two standing walls face each other with a gap in the one direction by the connecting portion, and the second folding member is When the first folding member is folded in the other direction when the first folding member is folded in the one direction together with the third folding member, the gap passes between the two standing walls along the other direction. It is solved by sliding.

  According to the above configuration, when the third folding member is folded, the two standing walls face each other with a gap in one direction by the connecting portion, and the second folding member is folded together with the third folding member, When the first bending member is bent in the other direction, the second bending member and the third bending member interfere with each other by sliding along the other direction through the gap between the two standing walls.

The fold portion of at least one of the first fold member, the second fold member, or the third fold member, or a connection portion between any one of them and the plate piece is formed thinner than the periphery, and the fold line is formed. Preferably it is formed.
If it is formed in this way, it can be folded at the thinly formed portion, the number of parts can be reduced without separately providing a connecting member for foldable connection, and integral molding becomes possible. Manufacturing is easy.

Furthermore, the two standing walls extend on a plane including the one direction and the other direction in the extended state and rise in the folded state, and are opposite to the mountain fold side from the standing portion. And the connecting part is formed at the projecting side end of the extending part so that the extending parts of the two standing walls can be rotated with each other. It is preferable that they are connected.
According to the above configuration, the two standing walls extend on a plane including one direction and the other direction in the extended state and rise in the folded state, and extend to the opposite side of the mountain fold side from the standing portion. The extending portion is present, and the connecting portion rotatably connects the extending portions of the two standing walls, so that the standing wall can be formed integrally with the extending portion and the standing portion, Since a gap can be formed by folding two standing walls into a folded state, the rigidity can be increased and the shape of the fixed planting plate member can be stabilized.

In addition, a fold portion of at least one of the first bending member, the second bending member, or the third bending member, or a connection portion between any one of these and the plate piece is connected by a hinge to form a fold. It may be.

It should be noted that members, arrangements, and the like described below do not limit the present invention, and it goes without saying that various modifications can be made in accordance with the spirit of the present invention.

(About the structure of the fixed planting plate member 1)
As shown in FIGS. 1 to 3, the fixed planting plate member 1 used for plant cultivation according to the present embodiment is configured so that the strain can be adjusted according to the growth of the plant.
Here, FIG. 1 is a perspective view showing an expanded state of the fixed planting plate member 1 according to the present embodiment, FIG. 2 is a perspective view showing an intermediate stage of the contracted state of the fixed planting plate member 1, and FIG. It is a perspective view which shows the 1 folding state. In FIG. 1, a broken line means a mountain fold line, and a two-dot chain line means a valley fold line.

  The planting board member 1 is disposed on a water tank (not shown) and is used for hydroponics for growing and cultivating a plant body placed on the planting board member 1 with a nutrient solution contained in the water tank. Specifically, the fixed planting plate member 1 includes a plurality of bases 11 arranged on the four circumferences of the fixed planting plate member 1, and a plate piece on which a pot (not shown) in which a plant body is placed is fixed on the base 11. 2 and 8, and a horizontal folding member 3, a vertical upper folding member 4, 10 and a vertical lower folding member 9 for expanding and contracting the planting plate member 1 in a substantially horizontal direction.

The base 11 has a plate shape that is long in the height direction, and is basically attached to each of the plate pieces 2 and 8 and to the plate pieces 2 at the four corners. In particular, the base 11 is attached at a position avoiding a planting hole 2a, which will be described later, so as not to hinder the placement of a pot (not shown).
Further, the adjacent base 11 is used for guiding the base 11 to a predetermined position when a lateral folding member 3, vertical upper folding members 4, 10 and vertical lower folding member 9 described later expand and contract. A guide bar 12 is stretched horizontally. Specifically, the guide rod 12 has a configuration that can be expanded and contracted, and the longitudinal direction that is the direction in which the lateral folding member 3, the longitudinal upper folding members 4 and 10, and the longitudinal lower folding member 9 expand and contract, and It extends in the horizontal direction and spans two in each direction.

The plate pieces 2 and 8 are arranged horizontally in a plate shape, and have planting holes 2a and 8a for holding a pot (not shown) in which a plant body such as a seedling is placed. The fixed planting plate member 1 according to the present embodiment has four rows in the vertical direction shown in FIG. 1 corresponding to one direction according to the present invention and a direction perpendicular to the vertical direction, and corresponds to the other direction according to the present invention. A total of 20 plate pieces 2 and 8 are arranged in a matrix of 5 rows in the horizontal direction.
The plate pieces 8 in the second row and the fourth row arranged in the vertical direction correspond to the first unit according to the present invention, and the first row, the third row, and the fifth row arranged in the vertical direction. The plate piece group 2 corresponds to the second unit according to the present invention. The first unit and the second unit correspond to the plate piece unit according to the present invention.

1 to 3, the plate piece 2 and the plate piece 8 are shown to be formed at substantially the same height. However, actually, the plate piece 2 is arranged to be higher than the plate piece 8 by a plate thickness a. That is, the base 11 that supports the plate piece 2 is formed to have a plate thickness a higher than the base 11 that supports the plate piece 8.
Further, the plate piece 8 is formed longer in the vertical direction than the plate piece 2 so that the distance between the plate pieces 8 adjacent in the vertical direction is shorter than the distance between the plate pieces 2 adjacent in the vertical direction. Is formed. Strictly speaking, the distance between the plate pieces 8 and the distance between the plate pieces 2 mean the distances between the respective end portions. In relation to the formation in this way, the distance between the valley fold 20d and the mountain fold 40b of the vertical lower folding member 9 (described later) connected to the longitudinally adjacent plate pieces 8 is vertical. It will be shorter than the distance between the valley fold 20b and the mountain fold 40a of the direction upper fold members 4 and 10.
Since the base 11 and the plate pieces 2 and 8 are formed as described above, when the fixed planting plate member 1 is expanded and contracted, the vertical upper folding members 4 and 10 and the vertical lower folding are formed as described later. Interference with the member 9 and interference between the longitudinal upper folding members 4 and 10 and the plate piece 8 can be avoided.

The horizontal folding member 3 corresponds to the first folding member according to the present invention, has a mountain fold 30a extending in the vertical direction in the middle thereof, and is configured to be extendable in the horizontal direction. The lateral folding member 3 has substantially the same length in the vertical direction as the plate piece 2 and is rotatably connected to the plate pieces 2 and 8 adjacent in the horizontal direction. The upper surface of the connecting portion is folded upward in the vertical direction so that the lateral folding member 3 bends upward about the connecting portion with the plate pieces 2 and 8. Is formed.
Specifically, the valley fold 20a is formed at a boundary portion in the lateral direction between the lateral folding member 3 and the plate piece 2, and the valley fold 20c is formed between the lateral folding member 3 and the plate piece 8. It is formed at the boundary portion in the lateral direction.

1 to 3, when the fixed planting plate member 1 is in the extended state, the lateral length on the side connected to the plate piece 2 and the lateral length on the side connected to the plate piece 8 in the lateral folding member 3. Is shown as being formed at approximately the same height. However, in actuality, when the fixed planting plate member 1 is in the extended state, the lateral length of the lateral folding member 3 on the side connected to the plate piece 8 is larger than the lateral length on the side connected to the plate piece 2. Is also formed to be about a plate thickness a long.
Thus, when the horizontal folding member 3 is formed, the vertical upper folding member 4 and the vertical lower folding member 9 interfere when the fixed planting plate member 1 is expanded and contracted as will be described later. You can avoid that.

  The vertical upper folding members 4 and 10 correspond to the third bending member according to the present invention, and are configured to include two standing walls 4a and 10a and connecting portions 4b and 10b connecting them, respectively. Between the plate pieces 2 adjacent to each other in the vertical direction through a valley fold 20b extending in the horizontal direction. Here, the vertical upper folding member 4 is disposed at both ends in the horizontal direction in the fixed planting plate member 1, whereas the vertical upper folding member 10 is the inner side in the horizontal direction in the fixed planting plate member 1. Are arranged.

  The standing walls 4a and 10a extend substantially horizontally when the fixed-planting plate member 1 is in the extended state as shown in FIG. 1, and each of the standing walls 4a and 10a is valley-folded in each of the vertically adjacent plate pieces 2 and 8. It is connected via the part 20b. When the fixed planting plate member 1 is in the folded state as shown in FIG. 3, the standing walls 4 a and 10 a are bent upward about the valley fold 20 b and extend substantially vertically.

  The connecting portions 4b and 10b are portions for connecting two standing walls 4a and 10a, which are connected to each of the plate pieces 2 and 8 adjacent in the vertical direction, via the mountain fold portions 40a and 40c. The connecting portions 4b and 10b form a gap S (shown in FIG. 7) in the two standing walls 4a and 10a when the fixed planting plate member 1 is in the folded state as shown in FIG.

  The vertical upper folding members 4 and 10 are folded in the vertical direction by being folded at the valley folds 20b and then being folded at the mountain folds 40a and 40c. Will be extended.

The vertical lower folding member 9 corresponds to a second folding member according to the present invention, and includes a valley fold 20d extending in the horizontal direction between the plate pieces 8 constituting the first unit and adjacent in the vertical direction. It is intervened.
And the vertical direction lower side fold member 9 has the one mountain fold part 40b of the mountain fold extended in the horizontal direction in the vertical direction center. The vertical lower folding member 9 is folded in the vertical direction by being folded at the valley fold portion 20d and then being folded at the mountain fold portion 40b. It will be.

  Further, in the extended state of the fixed planting plate member 1 shown in FIG. 1, a cut 5 is formed on the mutually opposing surfaces of the horizontal folding member 3, the vertical upper folding members 4, 10 and the vertical lower folding member 9. The cut 5 enables the members to extend and contract in the horizontal direction without interfering with each other.

In particular, the vertical upper folding members 4 and 10 and the vertical lower folding member 9 are alternately arranged in the horizontal direction. By arranging in this way, although the details will be described later, the bending operation of the lateral folding member 3 is not hindered.
In the fixed planting plate member 1, the one composed of the plate pieces 2 and 8 in two rows in the horizontal direction and two rows in the vertical direction is the minimum unit that can be expanded and contracted in the vertical direction and the horizontal direction.

(About the operation of the fixed planting plate member 1)
As shown in FIGS. 2 and 3, the fixed planting plate member 1 configured as described above includes mountain fold portions 40 a, 40 b, 40 c and valleys in the vertical upper folding members 4, 10 and the vertical lower folding member 9. By changing the bending degree of the folding portions 20b and 20d, the vertical stock between the plate pieces 2 and 8 can be changed.
Similarly, by changing the bending degree of the mountain fold part 30a and the valley fold parts 20a, 20c in the horizontal foldable member 3, the horizontal strain between the plate fragments 2, 8 can be changed.

As described above, in the fixed planting plate member 1 in the extended state, the vertical upper folding members 4 and 10 and the vertical lower folding member 9 are alternately arranged in the horizontal direction.
The distance between the valley fold portion 20d and the mountain fold portion 40b serving as the folding fulcrum of the vertical lower folding member 9 connected to the plate piece 8 adjacent in the vertical direction is the fulcrum of the vertical upper folding members 4 and 10. It is formed shorter than the distance between the valley fold 20b and the peak fold 40a.
For this reason, when the vertical upper folding members 4 and 10 are bent using the valley fold 20b as a folding fulcrum, and the vertical lower folding member 9 is bent using the valley fold 20d as a folding fulcrum, the vertical lower folding is performed. The member 9 slides in the lateral direction through the gap S (shown in FIG. 7) between the two standing walls 4a so as to lie under the vertical upper folding members 4 and 10. Therefore, it is possible to prevent the vertical upper folding members 4 and 10 and the vertical lower folding member 9 from crossing and interfering with each other in the vertical direction.
Further, as described above, the base 11 that supports the plate piece 2 is formed to have a plate thickness a higher than the base 11 that supports the plate piece 8. Can be prevented from interfering with each other.

  Therefore, as shown in FIG. 2, when the horizontal folding member 3 is folded in the horizontal direction, the vertical upper folding members 4, 10 adjacent to the horizontal direction and the vertical lower folding member 9 do not come into contact with each other. Moreover, since the vertical direction upper folding members 4 and 10 and the board piece 8 do not contact | abut, the folding operation | movement to the horizontal direction of the fixed planting board member 1 will be performed smoothly.

In the state shown in FIG. 3, the lateral end surfaces 5 a and 5 c of the longitudinal upper folding members 4 and 10 adjacent in the lateral direction and the lateral direction below the longitudinal upper folding members 4 and 10 are adjacent. A lateral end face (not shown) of each of the vertical lower folding members 9 is in a state of surface matching in the lateral direction. Further, the lateral folding member 3 and the vertical side surfaces of the upright walls 4a and 10a of the vertical upper folding members 4 and 10 are in a state of surface matching in the vertical direction.
Thus, the fixed planting plate member 1 has its rigidity enhanced by the adjacent portions being in a face-to-face state in the folded state.

  When the planting plate member 1 is actually used, the plant body to be placed is compacted as the folded state shown in FIG. 3 while the plant body is a seedling, and the state of FIG. 2 and the state of FIG. 1 as the plant body grows. By making the fixed planting plate member 1 extend, the space can be effectively used.

(About mountain folds and valley folds)
Next, the mountain folds 30a, 40a, 40b, and 40c and the valley folds 20a, 20b, 20c, and 20d will be described with reference to FIGS.
Here, FIG. 4A is a schematic diagram showing the cut 6a that forms the mountain folds 30a, 40a, 40b, and 40c, and FIG. 4B forms the mountain folds 30a, 40a, 40b, and 40c. FIG. 5A is a schematic view showing the hinge 6b, FIG. 5A is a schematic view showing the cut 7a forming the valley folds 20a, 20b, 20c, and 20d, and FIG. 5B is a view showing the valley folds 20a, 20b, 20c, It is a schematic diagram which shows the hinge 7b which forms 20d.

As shown in FIG. 4A, the notch 6a is formed on the upper surface side, so that the notch 6a portion functions as a thin hinge. This configuration can be used for the mountain folds 30a, 40a, 40b, and 40c.
Similarly, as shown in FIG. 5A, the notch 7a is formed on the lower surface side, so that the notch 7a part functions as a thin hinge. This configuration can be employed for the valley folds 20a, 20b, 20c, and 20d.
In this way, the cuts 6a and 7a can form folds without preparing separate parts.

On the other hand, as shown in FIG. 4 (B), if the hinge 6b is formed on the lower surface side, the mountain folds at each of the above-mentioned parts can be performed also by the hinge 6b.
Similarly, as shown in FIG. 5B, if a hinge 7b is formed on the upper surface side, valley folding at each of the above-described parts can be performed by the hinge 7b.
In this way, the hinges 6b and 7b can form folds without providing a flexible material portion. In particular, according to the hinges 6b and 7b, it is possible to form folds and separate them at the hinges 6b and 7b. That is, the hinge pieces 6b and 7b allow the plate pieces 2 and 8, the horizontal folding member 3, the vertical upper folding members 4 and 10, and the vertical lower folding member 9 to be newly attached, and can be removed conversely. It becomes possible. Therefore, the fixed planting plate member 1 can be made larger or smaller, and can be easily attached to a water tank (not shown) having a predetermined size, and versatility can be improved.

  In addition, the fixed planting board member 1 may be provided with both the site | part which forms a crease | fold by the notches 6a and 7a, and the site | part which forms a crease | fold by hinges 6b and 7b. In particular, when the folds are formed by the hinges 6b and 7b on the outside of the fixed planting plate member 1, depending on the size of the water tank, the plate pieces 2 and 8, the lateral folding member 3, the longitudinal upper folding member 4, 10 and the vertical lower folding member 9 can be easily removed and attached, and expandability is improved.

The vertical upper folding member 14 includes two standing walls 14a partially including a portion formed in a L-shaped cross section with the upright portion 14b spreading in a plane as a base, and a connection pin corresponding to the connection portion according to the present invention. 14d.
When the fixed planting plate member 1 shown in FIG. 8B is extended, the two standing walls 14a extend from the upright portion 14b in a direction opposite to the mountain fold side and in a direction perpendicular to the vertical direction and the horizontal direction. The extending portions 14c are formed at portions facing each other.
More specifically, the extending portions 14c of the two standing walls 14a protrude from the upstanding portions 14b in the opposite directions in the vertical direction, are intermittently formed in the horizontal direction, and are alternately combined to form a mountain fold. It is a direction opposite to the side and extends in a direction orthogonal to the vertical direction and the horizontal direction. The extending portions 14c of the two standing walls 14a are connected to each other by connecting pins 14d so as to be rotatable with respect to each other at the projecting end.

Since the extending portion 14c formed in this manner is connected by the connection pin 14d, when the vertical upper side folding member 14 is folded, as shown in FIG. 8A, the standing portions 14b of the two standing walls 14a. The gap S is formed by the total distance between the connection pin 14d and the connection pin 14d.
According to the vertical upper folding member 14 having such a configuration, since there is no thin fold portion like the vertical upper folding members 4, 10, rigidity can be improved and a long life can be achieved.

Furthermore, in order to stabilize the form in the state which contracted the fixed planting board member 1 besides the said modification, as shown in FIG. 9, the fixed planting board member 1 is the side surface ( It is preferable to provide the locking projection 13 on the upper surface in the extended state.
The locking projection 13 has a semicircular cross section and is formed to extend in the vertical direction in a state in which the vertical upper folding members 4 and 10 are extended. The locking projections 13 are formed on each of the two standing walls 4a and 10a in the one vertical upper folding member 4 and 10 at a portion intersecting the horizontal folding member 3 in the vertical upper folding member 4 and 10. The transverse folding member 3 is formed in a double-piece set separated by a plate thickness a.

Specifically, it is formed one by one so that the outer edges of the locking projections 13 are along the valley folds 20a on the lateral side of the plate pieces 2 and 8 that are adjacent in the vertical direction. One piece is formed at a position 2a away from the pieces 2 and 8 laterally outward.
Since the locking projections 13 are formed in this manner, in the folded state of the fixed planting plate member 1 shown in FIG. 9, the lateral folding member 3 in which the pair of locking projections 13 are folded is sandwiched. .
In this way, the lateral folding member 3 is clamped by the locking projection 13, so that the posture is stabilized. Further, the vertical upper folding members 4 and 10 are sandwiched between the lateral folding members 3 having a stable posture on both sides in the vertical direction, so that the posture is stabilized. That is, the mutual posture is stabilized, and the lateral folding member 3 and the vertical upper folding members 4 and 10 can be prevented from falling down to the plant body side in the pot held in the planting hole 2a.

  In addition, since the latching protrusion 13 has a shape extending in a semicircular cross section as described above, it is preferable because the folding operation of the lateral folding member 3 is difficult to be hindered. As long as the lateral folding member 3 can be sandwiched, the shape is not limited to this. For example, it may be a trapezoidal cross section or other polygonal shapes, and further may be protrusions provided in parallel with a space of 2a.

  The above embodiment is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the spirit of the present invention, and of course, the present invention includes equivalents thereof.

  For example, you may make it form said latching protrusion 13 in the vertical direction upper side folding member 14 which concerns on a modification.
