Japanese Unexamined Patent Publication No. 2009-45015 (paragraph 0021, FIG. 2)

However, in the most common usage, in order to allow the planting floor material to absorb water sufficiently, a sufficient amount of planting water exceeding the water absorption capacity of the planting floor material is supplied to the water storage part of the planting container. There is.

In such a case, in the planting device described in Patent Document 1, there is a possibility that the planting water exceeding a certain amount will be left for a long time from the upper end of the overflow pipe, and the planting water will be left for a long time. There was a risk of losing aesthetics.

Then, the objective of this invention considers the subject which the planting apparatus by the prior art illustrated above gives, even if it supplies the water for planting of the quantity exceeding the water absorption capability of a planting floor material to the water storage part of a planting container. An object of the present invention is to provide a planting apparatus in which the aesthetics may be impaired.

The characteristic configuration of the planting apparatus according to the present invention is:
A planting container having a water storage part capable of storing water for planting and a planting space on which a water-absorbing planting flooring can be placed, and a water supply means for supplying water for planting to the water storage part ,
An overflow pipe for draining water for planting exceeding a predetermined height is provided in the water reservoir,
A drain portion having a drainage capacity lower than a water supply speed of the water supply means is provided on the bottom surface of the water storage portion.

In the planting device having the above-described characteristic configuration, since the drain part having a drainage capacity lower than the water supply speed of the water supply means is provided on the bottom surface of the water storage part, when the water supply to the water storage part by the water supply means ends Planting water remaining in the reservoir without being absorbed by the planting material is drained by the drain.

Therefore, the water for planting will not be left in the water storage section for a long time, and there will be no fear that the planting floor material will generate wrinkles or the like, or there will be no harmful insects in the water for planting, and the aesthetics will not be impaired. .

Moreover, since the drainage capacity of the drain part is lower than the water supply speed of the water supply means, the water for water supply to the water storage part by the water supply means holds the water for planting at an appropriate height in the water storage part. Appropriately absorbs the water for planting and reveals the state of water retention.

In another feature of the present invention, a drain pipe communicating with the overflow pipe is formed to project downward from the water storage section, and the drain section communicates the bottom surface of the water storage section and the inner surface of the drain pipe. It is in the point formed.

For example, if the drain part is formed at a position different from the installation position of the overflow pipe or drain pipe, even if drainage of excess planting water is possible, the water for planting that has entered the drain part is The bottom surface of the bottom wall member that forms the bottom of the water reservoir is easy to move laterally, so the bottom surface of the bottom wall member is contaminated along with the movement, and from the boundary of the planting containers stacked up and down There is a risk of problems such as oozing out.

However, if it is this structure, the water for planting which entered the drain part first moves down along the inner surface of the drain pipe formed to project downward from the water storage part, and falls from the lower end of the drain pipe. In general, the water storage part of the lower planting container and the surface of the planting floor material are surely reached.

Moreover, if it is this structure, compared with the structure to which the water for planting which approached the drain part moves below along the outer surface of the drainage pipe, the plant drained from the drain part of the bottommost planting container Water can be reliably collected into an appropriate tank by using a hose fitted on the drain pipe.

Another feature of the present invention is that the drain portion extends so as to form an angle with respect to the vertical direction.

With this configuration, the planting water drained downward from the drain part by its own weight falls to a position displaced laterally from directly below the drain part, so that it is installed in the planting container one step below. It is convenient that the planted flooring will be irrigated.

Another feature of the present invention lies in that a foreign matter catching convex portion for catching foreign matter contained in the planting water is provided on the side of the drain portion.

With this configuration, even when foreign matter is floating on the surface of the planting water stored in the water storage part, in the water or near the bottom of the water storage part, many of these foreign substances are captured by the foreign matter catching convex part. Therefore, the drain portion is not easily blocked by these foreign substances, and a normal drainage state is ensured.

It is connected by 19c.

Since the guide tube 13 and the rear long side wall 4 are partitioned by the third reinforcing rib 19 c, the second reinforcing rib 19 b formed between the guide tube 13 and the partition wall 6 has the guide tube 13. A notch 19p that allows the planting water W to come and go between the two unit planting spaces 2a located on the left and right is formed.

The height of the lowermost end of the notch 19p is about 7 to 8 mm, and is set to be sufficiently lower than the height of the overflow pipe 10 (about 14 mm).

In addition, instead of the notch 19p formed in the 2nd reinforcement rib 19b, the water for planting between the two unit planting spaces 2a located in the right and left of the guide cylinder 13 near the lower end of the 3rd reinforcement rib 19c A notch that allows W to come and go may be provided.

For the convenience of stacking a plurality of planting containers 1 up and down, the upper edge of each partition wall 6 is an inclined upper edge 6 a corresponding to the inclination of the bottom wall 3.

For the same purpose, a fitting step 3 s is provided on the periphery of the bottom wall 3, and a circular columnar body 12 a provided on the lower edge of the short side wall 5 is provided on the upper edge of the short side wall 5. A recessed portion 14 to be fitted is provided.

That is, as shown in FIG. 4, when the planting containers 1 are stacked up and down, the lower surface of the bottom wall 3 of the planting container 1 positioned above is inclined by the partition wall 6 of the planting container 1 positioned below. It is set so as to contact the upper edge 6a.

Furthermore, almost simultaneously with the above-mentioned contact, the step 3s of the bottom wall 3 of the planting container 1 positioned above is located at the upper surface opening of the planting container 1 positioned below, and the columnar body 12a is recessed. 14 is set to be fitted.

The lid member 1a that can be placed in the upper surface opening of the planting container 1 located at the top is provided with a convex portion 15 that fits into the concave portion 14 of the short side wall 5.

Further, a guide member 16 is provided on the lower surface of the lid member 1a for appropriately holding the direction of the tip end portion of the water supply hose H2 (or the branch joint J2 attached in the vicinity of the tip end portion) particularly in the left-right direction. Yes.

In addition, the columnar body 12a provided at the lower edge of the short side wall 5 can be used as means for supplying the water W for planting from the side as needed.

In this case, a through hole is formed in the wall member sealing the inside of the columnar body 12a, and a hose for pumping up water for planting may be connected to the through hole.

As illustrated in FIG. 1, planting water for connecting a plurality of stages of planting containers 1 on a casing 1 c disposed on a floor surface such as a room by fitting each part and supplying water to each planting container 1. The water tank 1b for planting which can store W can be implemented with the form arrange | positioned inside the casing 1c.

In the example shown in FIG. 1, the contour shape in plan view is made common between the casing 1 c and the planting container 1, and the pump 30 is installed inside the planting water tank 1 b, thereby The overall appearance is simple and excellent.

Excess planting water W drained from the overflow pipe 10 or the like of each planting container 1 is drained from the drain pipe 11 connected below the lowermost overflow pipe 10 and the lower end of the drain pipe 11. It is collected in the planting water tank 1b via the hose H3. The inner diameter of the overflow pipe 10 and the drain pipe 11 is about 14 to 15 mm.

The planting water W collected in the planting water tank 1b is supplied from the joint H1 to the joint hose H1 that connects the outlet of the pump 30 and the joint J1 installed on the upper surface of the planting water tank 1b. It can be used without waste in the form of being supplied to the uppermost planting container 1 through the water supply hose H2 guided upward through the.

The front end of the water supply hose H2 is branched into two by the branch joint J2, and is supplied almost uniformly to the left and right unit water storage portions 8a of the uppermost planting container 1.

Each planting flooring A is placed with its lower part immersed in planting water W in the unit reservoir 8a. Therefore, the planting water W can be supplied to the root R of the plant P and planted while each planting floor material A absorbs the planting water W.

As described above, the front bottom wall 3b on which the planting flooring A is placed has an inclination angle α that is positioned higher on the opening side of each unit planting space 2a and lower on the side farther from the opening. It is formed in the inclined surface which has.

Therefore, as shown in FIG. 2, the planting floor material A is immersed in the planting water W on the side away from the opening, and the opening side is slightly immersed in the planting water W. It will be in the state which is not immersed in the water W.

As a result, it is possible to secure a large rhizosphere of the plant P (region where the root R of the plant grows and grows), and a sufficient amount of planting water W is supplied to the rhizosphere. Therefore, good growth of the plant is ensured.

(Drain configuration)
As shown in FIG. 3 to FIG. 10, on the bottom surface of the water storage part 8, drain parts 20a, 20b, 20c, 20d, 20e for draining the planting water W remaining in the water storage part 8 in a relatively short time. 20f is provided.

Therefore, when the water supply to the water storage unit 8 by the pump 30 is completed, the planting water W that is not absorbed by the planting flooring material A and remains in the water storage unit 8 is drained parts 20a, 20b, 20c, 20d, 20e, and 20f. Therefore, the water reservoir 8 is not left for a long time. As a result, pests, moths and other microorganisms are less likely to be generated in the planting flooring material A and the planting water W.

The drain portions 20a, 20b, 20c, 20d, 20e, and 20f are all formed so as to communicate the bottom surface of the water storage portion 8 and the inner surface of the drain pipe 11.

The inner diameter of each hole or the gap size of the slit constituting each drain part 20a, 20b, 20c, 20d, 20e, 20f is set so that the drainage capacity by the drain part is lower than the water supply speed of the pump 30.

Therefore, since the water for planting W is held at an appropriate height such as 10 mm or more in the water storage unit 8 during water supply to the water storage unit 8 by the pump 30, the planting floor material A appropriately uses the water for planting W. Water can be absorbed with efficiency and the state of water retention can be revealed.

Further, the inner diameter of the holes or the dimensions of the slits constituting the drain portions 20a, 20b, 20c, 20d, 20e, and 20f are caused by foreign matters such as particles and fibers contained in the water W for planting. , 20d, 20e are set to have appropriate sizes that are difficult to be blocked.

(First embodiment)
The drain portion 20a according to the first embodiment shown in FIGS. 3 to 5 has one through hole shape formed on the side surface of the overflow pipe 10, and the through hole extends in the radial direction of the overflow pipe 10, and The position of the lower end of the water coincides with the level of the bottom surface of the water reservoir 8. Here, the inner diameter of the drain portion 20a is about 5 mm.

More specifically, as illustrated in FIG. 5A, a concave wall having a reverse arc shape in which a part of the cylindrical portion constituting the overflow pipe 10 protrudes radially inward in a plan view. The drain part 20a is formed to penetrate the lower end of the concave wall part 10a laterally so as to allow the bottom surface of the water storage part 8 and the inner surface of the drain pipe 11 to communicate with each other.

A pair of left and right foreign matter catching convex portions 21a projecting radially outward are provided on the side of the upstream end portion of the drain portion 20a. As shown in FIG. 5B, the foreign matter capturing convex portion 21a has a partial spherical shape having a center at a position where the upper surface of the rear bottom wall 3a and the outer peripheral surface of the concave wall portion 10a intersect.

The concave wall portion 10a has a circumferential length slightly less than a quarter of the entire circumference of the overflow pipe 10 in a plan view, and is disposed so as to face the outermost unit planting space 2a. The end portion is disposed so as to be adjacent to the first reinforcing rib 19a.

As a result, the pair of left and right drain portions 20a are configured to extend rearward and leftward and rightward in plan view.

Since the drain part 20a is extended in the horizontal direction here so as to form an angle with respect to the vertical direction, most of the planting water W discharged from the drain part 20a is illustrated in FIG. 5 (b). Thus, it falls while drawing a parabola that is laterally separated from the concave wall portion 10a as it goes downward, and is not inside the overflow pipe 10 of another planting container 1 positioned below, but other than the overflow pipe 10 To the rear bottom wall 3a.

(Second Embodiment)
In the planting container 1 illustrated in FIG. 6, a flat wall portion 10 b is formed in a part of a cylindrical portion constituting the overflow pipe 10, and a drain portion 20 b is provided on the flat wall portion 10 b. .

The flat wall portion 10b faces the opening of the outermost unit planting space 2a and is inclined with respect to the first reinforcing rib 19a in plan view.

The drain portion 20b is in the form of a through hole formed laterally at the lower end of the flat wall portion 10b, and allows the bottom surface of the water storage portion 8 and the inner surface of the drain pipe 11 to communicate with each other.

In addition, a groove portion 10d having a width equal to the inner diameter of the drain portion 20b is formed in the vertical direction on the surface on the radial direction side of the flat wall portion 10b.

Here, the vicinity of the lower ends of the left and right flat wall portions 10b protruding outward in the radial direction with respect to the groove portion 10d constitutes the foreign matter capturing convex portion 21b.

Also here, since the drain part 20b is extended in the horizontal direction generally, most of the water W for planting discharged | emitted from the drain part 20b reaches below fundamentally so that it may illustrate in FIG.6 (b). It falls while drawing a parabola that is laterally separated from the flat wall portion 10b, and reaches the rear bottom wall 3a other than the overflow pipe 10 instead of the inside of the overflow pipe 10 of another planting container 1 positioned below.

(Third embodiment)
In the planting container 1 illustrated in FIG. 7, a part of the cylindrical portion constituting the overflow pipe 10 is configured by an arched wall portion 10 c that protrudes radially inward in plan view.

Unlike the first and second embodiments, the drain portion 20c is not part of the arch-shaped wall portion 10c, but the rear bottom so as to be along the ceiling portion located on the innermost radial direction of the arch-shaped wall portion 10c. The bottom surface of the water storage portion 8 and the inner surface of the drain pipe 11 are communicated with each other in the form of a through hole formed vertically with respect to the wall 3a.

The drain portion 20 c is formed at a position retracted radially inward from the basic outer peripheral surface of the overflow pipe 10. Here, the vicinity of the lower ends of the outer peripheral surfaces of the left and right overflow pipes 10 projecting outward in the radial direction with respect to the drain portion 20c constitutes the foreign matter capturing convex portion 21c.

As illustrated in FIG. 7B, most of the planting water W discharged from the drain portion 20c falls inside the drainpipe 11 and the overflow pipe 10 of another planting container 1 located below. It reaches the rear bottom wall 3 a other than the inside or the overflow pipe 10.

In the planting container 1 of the form illustrated in FIG. 7, the drain portion 20 c extends in the vertical direction, like the long side wall 4, the short side wall 5, and the partition wall 6.

Therefore, when the planting container 1 is manufactured by injection molding of resin, a planting container is provided by providing a convex part for molding the drain part 20c in two molds (not shown) divided up and down. The drain portion 20c can be simultaneously molded at the time of molding 1.

(Fourth embodiment)
The drain portion 20 d provided in the planting container 1 illustrated in FIG. 8 has a form of a vertical slit formed in a part of the cylindrical portion constituting the overflow pipe 10 in the circumferential direction.

The vertical slit extends in the vertical direction over the entire length of the overflow pipe 10 and communicates the bottom surface of the water storage section 8 and the inner surface of the drain pipe 11.

As illustrated in FIG. 8B, most of the planting water W discharged from the slit-shaped drain portion 20d falls inside the drainpipe 11 and is another planting container 1 positioned below. It reaches the inside of the overflow pipe 10 or the rear bottom wall 3 a other than the overflow pipe 10.

Also in the planting container 1 of the form illustrated in FIG. 8, the vertical slit-shaped drain portion 20 d extends in the vertical direction in the same manner as the long side wall 4, the short side wall 5, and the partition wall 6.

Therefore, a planting container is provided by providing a convex part for molding the drain part 20d in two molds (not shown) divided into upper and lower parts for manufacturing the planting container 1 by injection molding of resin. It is possible to simultaneously mold the drain portion 20d when molding 1.

(Fifth embodiment)
In the planting container 1 illustrated in FIG. 9, the overflow pipe 10 has a simple cylindrical shape, and the drain portion 20 d faces the lower end of the overflow pipe 10 so as to be adjacent to the outer surface of the first reinforcing rib 19 a. The bottom surface of the water storage section 8 and the inner surface of the drain pipe 11 are communicated with each other in the form of a through hole formed in the bottom.

Since this drain part 20e is extended in the horizontal direction generally, most of the water W for planting discharged | emitted from the drain part 20e is fundamentally so that it goes to the downward direction so that it may illustrate in FIG.9 (b). 1 falls while drawing a parabola that is laterally separated from the reinforcing rib 19a, and reaches the rear bottom wall 3a other than the overflow pipe 10 instead of the inside of the overflow pipe 10 of another planting container 1 positioned below.

(Sixth embodiment)
In the planting container 1 shown in FIG. 10, a communication passage 9 that communicates the unit water storage portions 8 a in the lateral direction is formed in a generally rectangular cutout shape at the lower part of each partition wall 6.

The drain portion 20f has a shape of one through hole formed on the side surface of the overflow pipe 10, and the through hole extends in the radial direction of the overflow pipe 10 and has an inner diameter of about 3 mm.

As shown in FIG. 10B, the position of the lower end of the through hole is set to a level 5 mm higher than the upper surface of the central bottom wall 3c constituting the substantial bottom surface of the water storage section 8. This is to further suppress the phenomenon in which the drain portion 20f is blocked by foreign matters such as particles and fibers contained in the planting water W.

As shown in FIGS. 6A and 6B, a part of the cylindrical part constituting the overflow pipe 10 (a part closer to the center than the corresponding partition wall 6 and the front part) is generally parallel to the long side wall 4. It is comprised by the flat wall part 10b extended to.

The drain portion 20f allows the bottom surface of the water storage portion 8 and the inner surface of the drainage pipe 11 to communicate with each other in a form penetratingly formed at the lower end of the flat wall portion 10b.

A foreign matter catching convex portion 21d protruding outward in the radial direction is provided on the left and right sides and below the drain portion 20f. The foreign matter catching convex portion 21d has a partially spherical shape that protrudes generally forward, particularly on the left and right sides of the drain portion 20f.

Since the drain part 20f is generally extended in the front-rear horizontal direction so as to form an angle with respect to the vertical direction, most of the planting water W discharged from the drain part 20f is basically downward. It falls, drawing the parabola spaced apart backward from the flat wall part 10b, and reaches the water storage part 8 or the planting flooring material A other than the overflow pipe 10 of the planting container main body 1 located below.

In this embodiment, the rear bottom wall 3a extending obliquely downward from the lower end of the long side wall 4 and the generally long side wall 4 toward the generally horizontal central bottom wall 3c below from the lower end of the rear bottom wall 3a. And an intermediate vertical wall 3d extending in parallel with each other. The drain portion 20f is arranged at a level near the middle of the intermediate vertical wall 3d in the vertical direction.

As shown in FIGS. 10A and 10B, a shielding plate 24 is provided above the upper end of the overflow pipe 10.

The shielding plate 24 enters the overflow pipe 10 from the upper end of the overflow pipe 10 or the drain part 20f, and the planting water W flowing down from the drain pipe 11 is not supplied to the water storage part 8 of the lower planting container 1. It is a means for suppressing the overflow pipe 10 from entering.

The shielding plate 24 is formed so as to project laterally from each of the outer side surfaces of the left and right partition walls 6 so as to intersect with the axial center of the overflow pipe 10 and cover most of the opening of the overflow pipe 10 in plan view. ing.

Of the upper end of the overflow pipe 10, a pair of connecting portions 25 extend straight upward toward the shielding plate 24 from two places before and after corresponding to the boundary with the partition wall 6, and the front end of the shielding plate 24 and Smoothly connected to the rear end.

A thin plate-like guide wall portion 26 is erected upward from the peripheral portion excluding the connecting portion 25 of the shielding plate 24. As a result, the upper surface of the shielding plate 24 is sandwiched between the partition wall 6 and the guide wall portion 26, thereby forming a groove-like flow path extending in the front-rear direction.

That is, even if the planting water W flowing down from the upper end of the overflow pipe 10 or the drain part 20f of the upper planting container 1 via the drain pipe 11 falls toward the overflow pipe 10, most of the upper surface of the shielding plate 24 is used. , Guided to the partition wall 6 and the guide wall portion 26, and supplied to the water storage portion 8 from the outer periphery of the overflow pipe 10 along the front and rear connection portions 25.

Therefore, a large amount of water for planting W does not directly enter the inner surface of the overflow pipe 10 from the drain pipe 11 of the upper planting container body 1.

Excessive planting water W accumulated in the water storage section 8 overflows into the overflow pipe 10 from the opening Q formed in the upper end of the overflow pipe 10 and the lower surface of the shielding plate 24.
