Documents of the prior art

Patent document 1: japanese patent laid-open No. 2010-239878 (paragraphs 0041 to 0043, FIGS. 1 and 2)

Problems to be solved by the invention

However, the plant cultivation apparatus described in patent document 1 has a large-sized form in which the water-retentive substrate is sandwiched between the front plate and the back plate and fixed by bolts, nuts, and the like, and thus it is difficult for a user or the like to change the structural form of the plant cultivation apparatus.

Disclosure of Invention

In view of the problems of the conventional techniques described above, it is an object of the present invention to provide a plant cultivation apparatus in which the configuration of the plant cultivation apparatus can be changed relatively easily.

The characteristic structure of the plant cultivation device of the invention comprises: one or more plant cultivation containers each having a water storage portion capable of storing water for plant cultivation and a plant cultivation space in which a water-absorbing plant cultivation plate material can be placed, the one or more plant cultivation containers being capable of forming an opening portion on at least a front surface side thereof, the opening portion exposing the plant cultivation plate material; and a frame member that detachably supports the one or more plant cultivation containers and surrounds the one or more plant cultivation containers, wherein a protruding portion is formed at a part of an outer periphery of the plant cultivation container, and an engagement opening portion that fits into the protruding portion is provided at an outer periphery of the frame member.

In the plant cultivation device having the above-described characteristic configuration, the plant cultivation container is supported and surrounded by the frame member having an arbitrary appearance color, and therefore, not only can a plant cultivation device having a high appearance be obtained easily, but also the frame member can be attached to and detached from the plant cultivation container, so that the configuration of the plant cultivation device can be changed relatively easily, and a method of use such as replacement of other frame members having different color tones can be performed, or the frame member can be separated from the plant cultivation container as needed, and used in a form in which only the plant cultivation container and the plant cultivation plate are combined.

In the plant cultivation apparatus having the characteristic configuration, when the frame member is attached to the plant cultivation container, the engagement opening formed in the outer periphery of the frame member and the protrusion formed in a part of the outer periphery of the plant cultivation container can be fitted to each other, and therefore, the plant cultivation container can be prevented from being inadvertently detached from the frame member.

Further, even when the frame member is formed of a material having a bright opaque color or the like, the level of the water for plant cultivation stored in the water storage portion in the plant cultivation container can be confirmed by the transparent water level confirmation portion of the plant cultivation container which is seen through the engagement opening of the frame member.

In another feature of the present invention, an overflow pipe for discharging water for plant cultivation exceeding a predetermined height is integrally formed in the plant cultivation container.

In this configuration, since the overflow pipe for draining the plant cultivation water supplied to the water storage part and exceeding the predetermined height is integrally formed, it is possible to easily prevent the water storage part from storing excessive plant cultivation water.

A further feature of the present invention is that the projection is at the lower end of the overflow tube.

In this configuration, when the plant growth container and the frame member are used in combination, the lower end of the overflow pipe and the engagement opening of the frame member are fitted to each other, and therefore, the plant growth container can be effectively prevented from being inadvertently detached from the frame member. In addition, in the present configuration, when the overflow pipe is used, the water for plant cultivation flowing down the overflow pipe can be smoothly discharged from the engagement opening of the frame member.

In another feature of the present invention, the overflow pipe is formed to be inclined with respect to a vertical line in a front view.

Even in this case, since the overflow pipe is inclined with respect to the vertical line in the front view, the opening portion disposed on the upper surface of the plant cultivation container and the vicinity of the upper end of the overflow pipe are inevitably disposed at positions displaced in the left-right direction, and the plant cultivation water supplied from the opening portion disposed on the upper surface of the plant cultivation container is hardly discharged from the overflow pipe to the outside while bypassing the water storage portion.

In another aspect of the present invention, at least one side surface of the plant container is formed with a transparent water level confirmation portion protruding therefrom, and the water level confirmation portion constitutes the protruding portion.

In this configuration, even when the frame member is formed of a material having a bright opaque color or the like, the level of the water for plant cultivation stored in the water storage unit in the plant cultivation container can be confirmed by the transparent water level confirmation unit of the plant cultivation container being seen through the engagement opening of the frame member.

In addition, in the present configuration, when the frame member is attached to the plant cultivation container, the engagement opening formed in the outer periphery of the frame member can be fitted to the water level confirmation part formed to protrude from the side surface of the plant cultivation container, and therefore, the plant cultivation container can be further prevented from being inadvertently detached from the frame member.

In another feature of the present invention, the plant cultivation container is integrally formed by blow molding of resin.

In this structure, molding can be performed using a parting die having a simple structure as compared with a structure in which molding is performed by injection molding, for example, and the amount of resin used is also small, so that weight reduction can be achieved, and reduction in manufacturing cost can be achieved. In addition, in this configuration, since the wall surface portion of the container constituting the plant cultivation container can be made sufficiently thin as compared with a configuration formed by injection molding, for example, the opening portion can be easily formed by a salesperson or a user using a simple tool such as a cutter.

In addition, in this configuration, since the wall portion constituting the plant cultivation container can be made sufficiently thin, the water level confirmation window can be provided to be elastically displaceable with respect to the entire side surface, and the plant cultivation container can be more easily attached to and detached from the frame member.

In still another feature of the present invention, the opening is disposed above a center of the upper and lower portions, and a pair of support portions that support the plant-growing plate material from a front-rear direction are formed to protrude from a lower inner surface of the opening.

In this configuration, since the plant-growing plate material can be supported from the front-rear direction by the pair of support portions formed so as to protrude inward below the opening portion of the plant-growing container, it is possible to suppress the fear of impairing the appearance of the plant grown on the plant-growing plate material, such as the plant-growing plate material swaying inside the plant-growing container or falling down in the plant-growing space to one of the front and rear directions to expose a part of the plant-growing plate material from the opening portion to the outside.

In another feature of the present invention, grip portions protruding into the plant growing space are integrally formed on both side surfaces of the plant growing container, and the grip portions also serve as restricting means for restricting lateral movement of the plant growing plate material.

In this configuration, the parts protruding into the plant cultivation space are integrally formed on both side surfaces of the plant cultivation container, whereby both functions of the handle portion usable as a means for operating the plant cultivation container and the regulating means for regulating the lateral movement of the plant cultivation plate material can be simultaneously realized with respect to the same parts.

In another feature of the present invention, the plant cultivation container has a back surface side facing the front surface side, and an auxiliary opening facing the opening can be formed in the back surface side.

In this configuration, since the position of the opening (auxiliary opening) can be selected between the front side and the back side, when the overflow pipe or the like is provided at one of the left and right ends of the plant cultivation container, for example, the opening (auxiliary opening) is provided at one of the front side and the back side, and the position of the overflow pipe can be set at an appropriate position on either of the left and right sides. In addition, in the present configuration, by providing the opening portions (auxiliary opening portions) on both the front side and the back side, the plant cultivation plate material and the plant planted in the plant cultivation plate material can be exposed from both the front and back sides of the plant cultivation container.

Detailed Description

The embodiment for carrying out the present invention will be described below with reference to the drawings.

Fig. 1 shows an example of a plant cultivation apparatus according to the present invention, and particularly shows the following states: the present invention relates to a plant cultivation container for cultivating a plant, which comprises only one rectangular transparent resin plant cultivation container a, a water-supplying plant cultivation sheet B accommodated in the plant cultivation container a, a frame C having relatively high rigidity and detachably fitted and fixed to the outer periphery of the plant cultivation container a, and a plant P planted in a plant cultivation through hole H of the plant cultivation sheet B.

The plant cultivation container a is integrally molded by blow molding of a resin such as polystyrene, and as illustrated in fig. 2, the plant cultivation container a after blow molding has: a front wall portion a1 and a rear wall portion a2 extending in parallel with each other with a gap in the front-rear direction, a bottom wall portion A3 closing a space formed by the front wall portion a1 and the rear wall portion a2 from below, a top wall portion a4 closing the space from above, a1 st side wall portion a5 closing the space from the left side, and a2 nd side wall portion a6 closing the space from the right side.

The front wall portion a1 and the rear wall portion a2 are substantially square, and the bottom wall portion A3, the top wall portion a4, the 1 st side wall portion a5, and the 2 nd side wall portion a6 extend along four sides of the squares.

As shown in fig. 2, the entire plant-cultivating container a is substantially rectangular plate-shaped, and the widths of the bottom wall portion A3, the top wall portion a4, the 1 st side wall portion a5, and the 2 nd side wall portion a6 are each a fraction of one side of the front wall portion a1 and the rear wall portion a2 (for example, the range of 1/5 to 1/3) in a state where the plant-cultivating container a is erected so that the front wall portion a1 and the rear wall portion a2 are substantially vertical.

In the blow molding, a resin parison is inserted between two half molds (not shown) having a parting surface extending along the bottom wall portion A3, the top wall portion a4, the 1 st side wall portion a5, and the 2 nd side wall portion a6, and compressed air is blown into the parison from two blow ports corresponding to the vicinities of the left and right ends of the top wall portion a4, whereby the parison can be pressed against the inner surface of the cavity in the half molds.

Therefore, in the vicinity of the left and right ends of the top wall portion a4 after blow molding, as shown by the broken lines, a part of the parison remains as two small dome-shaped surplus end portions 3A, 3B, and the surplus end portions 3A, 3B are cut off at the base end portions at an arbitrary timing after being released from the half-split mold, thereby forming two upper surface opening portions 4A, 4B in the vicinity of the left and right ends of the top wall portion a 4.

At least one of the upper surface openings 4A and 4B is used as a water supply port for supplying water W for plant cultivation to the plant P through the plant cultivation sheet B accommodated in the plant cultivation container a.

A burr E generated at the interface between the two half molds can be seen along the bottom wall portion A3, the top wall portion a4, the 1 st side wall portion a5, and the 2 nd side wall portion a6, and the plant-growing container a as a whole has a plane-symmetrical shape with a plane along the burr E as a center.

A horizontally long rectangular window formation planned line 5 is provided in a part of the front wall portion a1 (one example of the front and rear surfaces). The predetermined window formation line 5 is formed along the entire circumference of the rectangle in the following manner: the radially inner portion of the predetermined window-forming line 5 is formed in a step shape recessed into the blow-molded body by a depth of about 1 to 2 mm.

Since the blow-molded article is formed with an appropriate thickness, for example, when a salesperson or a user of the plant-growing container a cuts along the entire circumference of the line 5 by a cutter or the like using the above-described step difference or the like and removes the removal portion 5A on the inner side in the radial direction of the line 5, a rectangular plant-growing window portion 5B (an example of an opening) is formed in the front wall portion a1, as shown in fig. 3.

Further, since the completely similar predetermined window forming lines 5 are provided also in the rear wall portion a2 (an example of the front and rear surfaces) on the opposite side of the front wall portion a1, the plant cultivation window portion 5B (an example of the auxiliary opening portion opposing the opening portion) may be formed not only in the front wall portion a1 but also in the rear wall portion a2 (an example of the rear surface portion) or the plant cultivation window portion 5B may be formed in both the front wall portion a1 and the rear wall portion a2, depending on the intention of the salesperson or the user.

The internal space of the plant cultivation container a located below the lower edge of the plant cultivation window 5B thus formed functions as a water storage portion capable of storing the plant cultivation water W supplied from the upper surface openings 4A, 4B, etc., or as a plant cultivation space capable of placing the water-absorbent plant cultivation plate B.

As shown in fig. 4, the plant-growing sheet material B is stored in the plant-growing window 5B, but since fig. 4 shows the plant-growing sheet material B as being expanded by the plant-growing water by a factor of about 1.3, the plant-growing sheet material B before expansion can be easily stored in the plant-growing window 5B.

The plant-growing sheet material B is made of a mixture of, for example, urethane and pulverized wood chips, and can maintain moisture and air in a substantially uniform and well-balanced manner from the top to the bottom, and easily ensure air necessary for the growth and development of roots.

The plant-growing sheet material B is a slightly vertically long rectangle, and the height of the expanded plant-growing sheet material B is set to be substantially equal to or slightly smaller than the distance from the upper surface of the bottom wall A3 to the lower surface of the top wall a4 of the plant-growing container a, and the thickness of the expanded plant-growing sheet material B is set to be slightly smaller than the distance from the inner surface of the front wall a1 to the inner surface of the back wall a2 of the plant-growing container a.

The operation recess 6 (an example of the handle and the regulating means) for facilitating the operation of the plant-growing container a is formed in a recessed shape slightly above the upper and lower centers of the 1 st side wall portion a5 and the 2 nd side wall portion a6 of the plant-growing container a. When the 1 st side wall portion a5 and the 2 nd side wall portion a6 are viewed, the two operation recessed portions 6 are arranged symmetrically with respect to the burr trace E extending in the longitudinal direction, and the width of the expanded plant-growing plate material B is set to be substantially equal to or slightly smaller than the distance from the inner surface of the operation recessed portion 6 located on the 1 st side wall portion a5 side to the inner surface of the operation recessed portion 6 located on the 2 nd side wall portion a6 side. The operation recess 6 also functions as a restricting means for restricting the movement of the plant-growing plate material B housed in the plant-growing container a in the lateral direction.

The plant-cultivating window portion 5B formed along the predetermined window-forming line 5 is formed at a position displaced upward from the center of the front wall portion a1 in the vertical direction.

Similarly, five plant-growing through-holes H formed to penetrate through the plate-shaped plant-growing plate material B in the front-rear direction are also arranged at positions displaced upward from the center in the vertical direction as a whole.

As a result, as shown in fig. 5, the five plant-growing through-holes H disposed in the plant-growing plate material B are substantially uniformly distributed inside the plant-growing window portion 5B displaced upward in this manner in a state where the plant-growing plate material B accommodated in the plant-growing container a is swelled with the plant-growing water.

As can be understood from fig. 4 and 5, the plant-growing through hole H is not provided in a portion below the plant-growing plate material B disposed below the lower edge of the plant-growing window portion 5B, and the left and right side portions of this portion gradually narrow downward in the front view to form a tapered shape, thereby functioning as follows: the volume of the water storage part formed below the lower edge of the plant cultivation window part 5B is ensured to be larger.

A support protrusion 8 (an example of a support portion) horizontally extending in a long and narrow manner in the left-right direction protrudes in a rib shape into the blow-molded body from a position below the lower edge of the plant-cultivating window portion 5B of the front wall portion a1 and the rear wall portion a 2. These support protrusions 8 arranged at intervals in the front-rear direction come into contact with the expanded plant-growing plate B accommodated therein from the front-rear direction, thereby achieving an effect of substantially stabilizing the posture of the plant-growing plate B in a vertical shape.

As shown in fig. 6, an overflow part 10 is integrally formed at a position between the 1 st side wall part a5 and the bottom wall part A3 on the left side, and the overflow part 10 is used for automatically overflowing the plant cultivation water exceeding the original water level WL.

The overflow section 10 includes: a weir part 10A formed to protrude upward from the vicinity of the right end of the bottom wall part A3, and an overflow pipe 10B extending downward smoothly from the upper end of the weir part 10A and the lower end of the 1 st side wall part a5 without protruding laterally. The weir 10A and the overflow pipe 10B are connected by a thin plate rib-shaped reinforcement part 11.

The upper end of the weir 10A is disposed at the original water level WL, and the original water level WL is provided slightly below the lower edge of the plant-cultivation window 5B.

As shown in fig. 6, in the state immediately after the blow molding, since the lower end of the overflow pipe 10B is closed in the blind pipe shape, the overflow pipe 10 does not function as such, and when the lower end portion of the overflow pipe 10B is cut out substantially horizontally at the position of 10C by a salesperson, a user, or the like, the excess plant cultivation water exceeding the weir portion 10A first overflows downward through the overflow pipe 10B.

For example, when two plant growth containers a are used without using the frame C while being stacked up in the vertical direction, if the plant growth containers a have the same shape in which the plant growth window portions 5B are formed in the front wall portions a1, and the right and left centers of the plant growth containers a are aligned with each other, the lower end of the overflow pipe 10B of the plant growth container a disposed above is set to be naturally inserted through the upper surface opening 4A on the left side of the plant growth container a disposed below.

Further, as described above, since the position of the plant cultivation window 5B (opening, auxiliary opening) can be selected between the front wall a1 and the rear wall a2, the position of the overflow pipe can be set to a position suitable for the user on either the left or right by providing the plant cultivation window 5B on either the front wall a1 or the rear wall a 2.

Further, it is difficult to cause a situation in which the water for plant cultivation supplied to the inside of the plant cultivation container a from the upper surface opening 4A directly downward is not supplied to the water storage portion of the plant cultivation container a but is discharged to the outside of the plant cultivation container a through the overflow pipe 10B. This is because the overflow pipe 10B is gradually inclined inward in the front view from the upper end corresponding to the height of the weir portion 10A to the lower end, and therefore the upper end of the overflow pipe 10B and the upper surface opening 4A are displaced in the right-left direction of the plant growth container a. The reason for this is that, in general, the water for plant cultivation supplied into the plant cultivation container a from the upper surface opening 4A is absorbed by the plant cultivation plate material B or flows down toward the bottom of the interior of the plant cultivation container a along the vicinity of the surface of the plant cultivation plate material B.

As shown in fig. 6, a vertically long water level confirmation part 14 is formed to protrude from a2 nd side wall part a6 (an example of an outer periphery) on the right side of the plant growth container a. Since the plant cultivation container a is transparent as a whole, when only the plant cultivation container a and the plant cultivation plate B are used in combination, as will be described later, the actual water level of the plant cultivation water W can be confirmed from any direction of the plant cultivation container a. However, as shown in fig. 1, when a frame C made of an opaque material is generally used by being externally fitted to the plant cultivation container a, since the water level cannot be checked from the front of the frame C, the water level of the plant cultivation water W is checked by a water level check window 24 (an example of an engagement opening) formed through the side plate portion C4 on the right side of the frame C and the water level check portion 14 corresponding to the water level check window 24.

The frame C has: a substantially square 1-layer dash panel C1 having a rectangular window 20, and 4 side panels C2, C3, C4, and C5 extending at right angles from the four sides of the dash panel C1.

When the frame C is fitted to the plant cultivation container a, as shown in fig. 7, the front wall portion a1 on which the plant cultivation window 5B is formed is overlapped with the front panel portion C1.

An upper through hole 21 for supplying water for plant cultivation is formed in the side plate portion C3 on the top surface side of the frame C, and a lower through hole 22 for discharging excess water for plant cultivation flowing down from the overflow pipe 10B to the outside of the plant cultivation device is formed in the side plate portion C2 on the bottom surface side of the frame C.

The lateral width and height of the outside dimension of the plant-growing container a are approximately equal to the lateral width and height of the inside dimension of the frame C. The water level confirmation part 14 (an example of a protrusion) of the plant cultivation container a is formed to be capable of fitting with the water level confirmation window 24 of the frame C, and the lower through hole 22 (an example of an auxiliary engagement opening) on the bottom surface side of the frame C is capable of fitting with the lower end part (an example of a protrusion) of the overflow pipe 10B.

When the frame C is fitted to the outside of the plant container a, as illustrated in fig. 8, the plant container a is first inserted into the frame C in a posture inclined in a plan view, and the water level confirmation part 14 of the plant container a is brought close to the water level confirmation window 24 of the frame C, and then the first side wall part a5 of the plant container a is pressed into the inner side of the right side wall part C5 of the frame C while the plant container a is rotated so that the water level confirmation part 14 is fitted to the water level confirmation window 24, and finally the lower end part of the overflow pipe 10B is fitted to the lower through hole 22 of the frame C, thereby completing the fitting.

Even if the lower end of the overflow pipe 10B is opened by cutting or closed in an uncut state, the lower end of the overflow pipe 10B can be fitted into the lower through hole 22 of the frame C, and when the lower end of the overflow pipe 10B is opened, the through hole 22 functions as a drain port for draining the excess plant cultivation water W flowing out of the overflow pipe 10B.

The plant cultivation device in the state shown in fig. 1 can be suspended on the wall surface by forming the engaging hole 26 for suspension in a through shape at the left and right center of the back surface side of the side plate portion C3 on the top surface side of the frame C, and engaging the head portion of the nail-like attachment member or the like that is provided upright from the wall surface with the engaging hole 26 by a string or a hook that passes through the engaging hole 26.

A pair of front and rear avoidance concave portions 16 for passing the string or the hook are formed in the center of the top wall portion a4 of the plant growth container a, and these pair of front and rear avoidance concave portions 16 also function to support the vicinity of the upper end of the plant growth plate material B in the front-rear direction.

A horizontal linear indication mark 14A is formed to protrude from the water level confirmation part 14 of the plant cultivation container a, and the indication mark 14A indicates a reference water level corresponding to the height of the weir part 10A of the overflow part 10.

Fig. 9 shows an example of use in which 4 plant-cultivating containers a are engaged with each other inside a large frame CX in a state of being arranged in a state of being laid flat in the vertical direction.

Here, two plant-growing containers a stacked up and down facing right have plant-growing windows 5B formed in the front wall portion a1, and two plant-growing containers a stacked up and down facing left have plant-growing windows 5B formed in the rear wall portion a 2. Therefore, the overflow pipes 10B of the four plant cultivation containers a are all arranged in the center of the right and left sides, and thus the entire shape is symmetrical (right-left symmetrical).

Two upper through holes 21 for supplying water for plant cultivation are formed in the side plate portion C3 on the top surface side of the frame CX, and a lower through hole 22 (not shown) to be fitted to the lower end of the overflow pipe 10B is formed in the side plate portion C4 on the right side of the frame CX.

Further, all four water level confirmation windows 24 to be fitted to the water level confirmation parts 14 of the four plant cultivation containers a are formed in the left and right side plate parts of the frame CX.

When the lower ends of the overflow pipes 10B of at least the two plant cultivation containers a located above are opened and the plant cultivation water W is supplied from the upper surface opening 4A to the plant cultivation containers a located above, the excess plant cultivation water W for the plant cultivation container a located above is supplied to the two plant cultivation containers a located below through the overflow pipe 10B, and all the plant cultivation plates B stored in the four plant cultivation containers a can be kept in a water retaining state.

As can be understood from fig. 5 and the like, a plant cultivation apparatus may be used that: a plant cultivation device comprising a combination of a plant cultivation container A and a plant cultivation plate B without using a frame C.

Fig. 10 shows a state in which four plant cultivation containers a are arranged in a vertical and horizontal direction on a wall surface without using a frame C. Here, two plant-growing containers a stacked up and down facing right sides form the plant-growing window 5B in the front wall portion a1, and two plant-growing containers a stacked up and down facing left sides form the plant-growing window 5B in the rear wall portion a 2. Therefore, the overflow pipes 10B of the four plant cultivation containers a are all arranged in the center of the right and left sides, and thus the entire shape is symmetrical (right and left symmetrical).

The plant cultivation container a can be fixed to a wall surface by a dedicated attachment unit 30, as shown in fig. 10, for example. The attachment unit 30 includes a leg portion which is driven into the wall surface to be in an anchor shape, and a head portion 30A which is engaged into the left and right operation recessed portions 6 of the plant cultivation container a from the side.

In addition to the frame C shown in fig. 7, a frame member may be prepared in advance in which the arrangement of the water supply through hole 21 and the water discharge through hole 22 with respect to the window portion 20 is reversed left and right. In this case, a frame C in which a plant cultivation container a having a plant cultivation window portion 5B formed in a front wall portion a1 as shown in fig. 7 is fitted and a frame member turned right and left in which a fitted plant cultivation container a having a plant cultivation window portion 5B formed in a rear wall portion a2 is different from that of fig. 7 can be used in a state in which the frame member is stacked up and down.
