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.

A total of 20 plate pieces 2 arranged in a matrix in five rows in the horizontal direction are provided. In addition, the fixed planting board member 1 is formed so that the board piece 2 may be arranged on the outer periphery. In addition, the plate groups 2 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 2 group corresponds to the second unit or the third unit according to the present invention. The first unit, the second unit, and the third unit correspond to a plate piece unit.

  The lateral mountain fold portion 3 corresponds to the first bent portion according to the present invention, has a mountain fold fold 30 extending in the longitudinal direction in the middle, and is configured to be extendable and contractable in the lateral direction. Further, the lateral mountain fold portion 3 has substantially the same length in the vertical direction as the plate piece 2 and is connected to each of the plate pieces 2 adjacent in the horizontal direction. A valley fold 20a, which is a fold extending in the vertical direction, is formed in the connecting portion so that the lateral mountain fold 3 is bent upward with the connecting portion with the plate piece 2 as the center. .

  The vertical side valley fold part 4b corresponds to the second bent part according to the present invention, and the vertical side mountain fold parts 4a and 4c correspond to the third bent part according to the present invention. Both have a mountain fold fold 40a or a valley fold fold 40b extending in the lateral direction in the middle, and are configured to be stretchable in the vertical direction. Further, the vertical mountain folds 4a and 4c are connected to the plate pieces 2 adjacent in the vertical direction. A mountain fold portion 20b, which is a fold extending in the vertical direction, is formed at the connection portion so that the vertical mountain fold portions 4a and 4c are bent upwards around the connection portion with the plate piece 2. ing. In the extended state shown in FIG. 1, the horizontal length of the vertical mountain folds 4 a located at both ends in the horizontal direction of the fixed planting plate member 1 is the length of the plate piece 2 in the horizontal direction and half of the horizontal mountain fold 3. It is the total length. That is, the vertical mountain fold 4 a is disposed adjacent to the plate piece 2 and half of the horizontal mountain fold 3 in the vertical direction.

Moreover, in the expansion | extension state of the fixed planting board member 1 shown in FIG. 1, the vertical side mountain fold part 4c located other than the edge of the horizontal direction of the fixed planting board member 1 is the length of the board piece 2 in a horizontal direction, and a horizontal side mountain fold part. 3 and the total length. Further, the vertical mountain fold portion 4c is arranged adjacent to the fold portion of the horizontal mountain fold portion 3 adjacent in the horizontal direction across the plate piece 2 from the fold portion of the horizontal mountain fold portion 3 in the vertical direction. ing.
Similarly, in the extended state of the fixed planting board member 1 shown in FIG. 1, the vertical valley fold portion 4 b has a total length of the plate pieces 2 and the horizontal mountain fold portions 3 in the horizontal direction. Further, the vertical valley fold 4b is disposed in the vertical direction adjacent to the fold portion of the horizontal mountain fold portion 3 that is adjacent in the horizontal direction across the plate piece 2 from the fold portion of the horizontal mountain fold portion 3. ing.

  In the extended state of the fixed planting plate member 1, a cut line 5 is formed on the mutually opposing surfaces of the horizontal mountain fold part 3, the vertical mountain fold parts 4a and 4c, and the vertical valley fold part 4b. The cut 5 enables each member to operate without interference.

In particular, the vertical mountain folds 4a and 4c and the vertical valley fold 4b are arranged such that the mountain fold and the valley fold are adjacent to each other in the horizontal direction. Although the details will be described later by being arranged in this way, the bending operation of the lateral mountain fold portion 3 is not hindered.
In addition, in the fixed planting board member 1, what consists of the board piece 2 of 2 rows of horizontal directions and 2 rows of vertical directions is the minimum unit which can be expanded-contracted in the vertical direction and a horizontal direction.

In addition, as described above, the guide rod 12 is attached to the base 11 of the four-round circumference of the fixed planting plate member 1. The vertical mountain folds 4a are formed at both lateral ends of the fixed planting plate member 1 so that the vertical trough folds 4b do not interfere with the bending movement of the guide troughs 12b. Preferably it is arranged.
Therefore, the vertical mountain folds 4a and 4c and the vertical valley folds 4b arranged on the horizontal side of the fixed planting plate member 1 are alternately arranged, and the vertical mountain folds 4a are arranged at both ends in the horizontal direction. For convenience, the fixed planting plate member 1 is an odd-numbered row. That is, it is preferable that the fixed planting plate member 1 is composed of the plate pieces 2 in three rows and two rows, since the bending operation is not hindered by the guide rod 12.

(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 is configured by changing the folding degree of the folds of the vertical mountain folds 4a and 4c and the vertical valley fold 4b. It is possible to change between the strain 2 fragments.
As described above, the vertical mountain folds 4a and 4c and the vertical valley folds 4b are arranged so that the mountain folds and the valley folds are alternately adjacent to each other. For this reason, as shown in FIG. 2, when the horizontal mountain fold part 3 is bent and contracts in the horizontal direction, the adjacent vertical mountain fold parts 4a and 4c and the vertical valley fold part 4b do not come into contact with each other. The contraction operation in the lateral direction is not hindered.

  In the state shown in FIG. 3, the horizontal mountain fold part 3, the vertical mountain fold parts 4 a and 4 c, and the vertical valley fold part 4 b below the vertical mountain fold parts 4 a and 4 c (FIG. Each of (see)) is folded at the crease and is in a face-to-face state. Furthermore, in the vertical direction, the vertical end face 6d of the horizontal mountain fold 3 is in contact with the vertical side surfaces of the vertical folds 4a and 4c. Further, the lateral side end surfaces 5a and 5c of the longitudinal mountain folds 4a and 4c that are adjacent to each other in the contracted state are in contact with each other in the lateral direction.

  As described above, since the lateral end faces 5a and 5c of the adjacent vertical mountain folds 4a and 4c are in contact with each other, there is no portion that opens below the plate piece 2 inside the fixed planting plate member 1. . For this reason, the fixed planting plate member 1 is in the contracted state, even when the vertical valley fold 4b below the plate piece 2 is immersed in a nutrient solution in a water tank (not shown), the vertical valley fold 4b. Since it is not exposed upwards, sunlight from above can be blocked, and adhesion of mold and moss can be suppressed.

  When the planting plate member 1 is actually used, the contracted state shown in FIG. 3 is made compact while the plant body to be placed 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, with reference to FIG. 4 thru | or FIG. 7, the horizontal side mountain fold part 3, the vertical side mountain fold parts 4a and 4c, and the vertical side valley fold part 4b are demonstrated. 4 is a plan view showing the fixed planting plate member 1, FIG. 5 is a schematic view showing the VV cross section of FIG. 4, and FIG. 6A is a mountain fold portion made of a flexible material having a cut 6a. FIG. 6B is a schematic view showing a mountain fold part having a hinge 6b, and FIG. 7A is a schematic view showing a valley fold part made of a flexible material having a cut 7a. 7 (B) is a schematic diagram showing a valley fold having a hinge 7b.

(About interference between mountain folds and valley folds)
The horizontal side end surfaces 5a, 5b, 5c, in which the vertical side mountain folds 4a, 4c and the vertical side valley fold 4b are opposed to each other in the extended state, are formed to be inclined as shown in FIG. Specifically, the lateral end surfaces 5a and 5c facing the longitudinal valley folds 4b in the longitudinal mountain folds 4a and 4c are formed to be inclined downward from the vertical surface. On the other hand, the lateral end face 5b facing the longitudinal mountain folds 4a and 4c in the longitudinal valley fold 4b is formed to be inclined upward from the vertical surface.
As described above, the lateral end faces 5a, 5b, and 5c are formed to be inclined so that the fixed planting plate member 1 in the expanded state shown in FIG. 1 is contracted so that the lateral mountain fold portion 3 is folded. In doing so, it does not hinder its contraction action.

Specifically, when the lateral mountain fold portion 3 is contracted so as to be folded, the lateral end surfaces 5a, 5c and the lateral end surface 5b come into contact with each other, and vertical drag forces on the opposite sides are generated. For this reason, the vertical mountain folds 4a and 4c are automatically folded upward, and the vertical valley fold 4b is automatically folded downward.
Therefore, the force caused by the contact between the vertical mountain folds 4a and 4c and the vertical valley fold 4b is dispersed by the inclination of the horizontal end surfaces 5a, 5b and 5c, and the horizontal mountain fold 3 It is possible to prevent interference with the contraction operation of the. Furthermore, the vertical folds 4a and 4c and the vertical trough fold 4b are operated in a direction in which the vertical folds 4a and 4c and the vertical valley folds 4b are preferably folded by the distributed vertical force. Therefore, the fixed planting board member 1 slides smoothly in the lateral direction.

(About folds of mountain folds and valley folds)
As shown in FIG. 6 (A), a cut 6a is formed on the upper surface side of the mountain fold portion of the horizontal mountain fold portion 3 or the vertical mountain fold portions 4a and 4c, and the periphery thereof is made of a flexible material. If it consists of, it becomes possible to carry out a mountain fold in the notch 6a part.
Similarly, in the connection portion between the plate piece 2 and the horizontal mountain fold portion 3, the vertical mountain fold portions 4a and 4c, or the vertical valley fold portion 4b or the valley fold portion of the vertical valley fold portion 4b, FIG. If the cut 7a is formed on the lower surface side and the periphery thereof is made of a flexible material, valley folding is possible at the cut 7a portion.
In this way, the cuts 6a and 7a can form folds without preparing separate parts.

On the other hand, if the hinge 6b is formed on the lower surface side as shown in FIG. 6B in the mountain fold portion of the horizontal mountain fold 3 or the vertical mountain fold 4a, 4c, the mountain 6b is formed by the hinge 6b. A fold of the fold portion is formed.
Similarly, in the connecting portion between the plate piece 2 and the horizontal mountain fold portion 3, the vertical mountain fold portions 4a and 4c, or the vertical valley fold portion 4b or the valley fold portion of the vertical valley fold portion 4b, FIG. ), If the hinge 7b is formed on the upper surface side, the fold of the valley fold portion is formed by the hinge 7b portion.
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. In other words, the hinge piece 6b, 7b makes it possible to newly attach the plate piece 2, the lateral mountain fold part 3, the vertical mountain fold parts 4a, 4c, and the vertical valley fold part 4b, and can be removed conversely. Become. 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, the plate piece 2, the lateral mountain folds 3 and the vertical mountain folds 4a and 4c are formed according to the size of the water tank. Or the removal and attachment of the vertical side valley fold part 4b become easy, and an expansibility becomes favorable.

(About the relationship of the size of each part of the fixed planting plate member)

Moreover, c is half the length of these vertical widths in the state where the vertical mountain folds 4a, 4c or the vertical valley folds 4b are extended. In other words, c is the length that is the protruding height of the vertical mountain folds 4a, 4c from the plate piece 2 or the length that is the depth of the depression from the plate piece 2 of the vertical valley folds 4b in the contracted state. It is.
Furthermore, D is the horizontal length of the vertical mountain folds 4a, 4c or the vertical valley folds 4b.
Each subscript indicates the position of each part arranged in a matrix. The subscripts l, L, M, and N shown below are natural numbers, satisfying 1 <l <n, 1 <L <N, 1 ≦ M <N / 2, where 2M-1 is an odd number other than 1. .

The length relationship between the plate piece 2, the lateral mountain fold part 3, the vertical mountain fold parts 4a and 4c, and the vertical valley fold part 4b in the lateral direction of the fixed planting plate member 1 is expressed by the following formulas 1 to 4. Fulfill.

The left side of Expression 13 indicates a length obtained by adding the horizontal lengths of the plate fragments 2 at both ends in the horizontal direction of the fixed planting plate member 1. On the other hand, the right side indicates the horizontal length of any one plate piece 2 other than both ends in the horizontal direction.
By satisfy | filling Numerical formula 11 and Numerical formula 13, when the horizontal width of the whole fixed planting board member 1 is made into an expansion | extension state from a shrinkage | contraction state, it becomes possible to make it double length.

  In this way, the fixed planting plate member 1 is used in a contracted state by making the length of the stretched fixed planting plate member 1 twice the length of the contracted planting plate member 1. It is easy to calculate the space occupied when using the case and the extended state, and the layout design becomes easy.

Furthermore, in order to stabilize the form in the state which contracted the fixed planting board member 1, when the fixed planting board member 1 is provided with the latching protrusion 13 on the upper surface of the vertical side mountain fold parts 4a and 4c, as shown in FIG. preferable.
The locking projection 13 has a semicircular cross section, and is formed to extend in the vertical direction in a state where the vertical mountain folds 4a and 4c are extended. The locking projections 13 are separated by a thickness 2t of the lateral mountain fold 3 at the longitudinal mountain folds 4a at both ends in the lateral direction, and are arranged in two locations in two pairs, and at four locations in the longitudinal mountain folds 4c other than both ends. Is formed.

Specifically, it is formed one by one so that the outer edge of the locking projection 13 is along the fold on the lateral side in the plate piece 2 adjacent in the vertical direction, and further from the plate piece 2 in the horizontal direction. One is formed at a position 2t away from the outside.
And in the state which the horizontal side mountain fold part 3 and the vertical side mountain fold parts 4a and 4c shown in FIG. Become.
In this manner, the lateral mountain fold 3 is clamped by the locking projection 13, so that the posture is stabilized. Further, the vertical mountain folds 4a and 4c are sandwiched between the horizontal mountain folds 3 having a stable posture on both sides in the vertical direction, thereby stabilizing the posture. That is, the mutual posture is stabilized, and it is possible to prevent the lateral mountain fold part 3 and the vertical mountain fold parts 4a and 4c from falling to the plant body side in the pot held in the planting hole 2a.

  In addition, it is suitable for the latching protrusion 13 to have a shape extending in a semicircular cross section as described above, because it is difficult to hinder the bending operation of the lateral mountain fold 3. However, the present invention is not limited to this shape as long as the lateral mountain fold 3 can be sandwiched. For example, the shape may be a trapezoidal cross section or other polygonal shapes, or may be protrusions provided in parallel with an interval of 2t.
