Abstract

PURPOSE:To prevent water grasses from coming out and to keep them in a standing state without giving a sense of incompatibility to the atmosphere to the water tank by sandwiching culture soil between a pair of nonwoven fabric layers, fixing the root part of the water grasses, laying river sand thereon to, form the surface layer. CONSTITUTION:Water grasses are planted in the bottom sand in a state where the root part of each water grass is nipped, e.g. by a root-fixture or a root- fixture having an opening part capable of opening and closing respectively set to a fiber layer-containing layered material or to a sponge material. Culture soil 13 is sandwiched between a pair of nonwoven fabric sheets 11 and 12 in the layered material 10 and the respective root parts 15a and 16a of the water grasses 15 and 16 are inserted through the nonwoven fabric layer 11 into the culture soil 13. River sand is laid on the nonwoven fabric layer 11 to form the surface layer 18. For preventing the layered material 10 from coming up, a thin metal plate 19 such as a lead plate is placed on the laminated material 10 as necessary.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquatic plant fixing tool used for stably planting aquatic plants on bottom sand laid inside an ornamental water tank.

[0002]

2. Description of the Related Art It is easy to get tired of simply swimming with ornamental fish such as goldfish and tropical fish in a water tank. Therefore, by planting aquatic plants in the bottom sand laid on the bottom of the aquarium or arranging pseudo rocks, an atmosphere as close to nature as possible is created.

[0003] Examples of aquatic plants placed in the aquarium include floating plants and grasses that have roots in the bottom sand and leaves that float in the water. The latter aquatic plants are placed in the aquarium by planting aquatic plants one by one in the bottom sand. However, replacement of water or movement of aquatic animals may cause the surface layer of the bottom sand to fly up, causing the roots to slip out of the bottom sand. As a result, aquatic plants float in the water, creating an extremely messy impression inside the aquarium.

Various means have been conventionally employed to prevent the roots of aquatic plants from slipping out of the bottom sand and to maintain the aquatic plants in the water in the desired state. For example, there is a method in which a pot in which aquatic plants are firmly planted is placed inside the aquarium, a method in which a lead plate is wound around the root of the aquatic plant and the submerged in the aquarium.

[0005]

When using a pot in which aquatic plants are planted, the shape and color tone of the pot are restricted because of harmony with other accessories arranged in the aquarium. Further, when thinning the number of water plants that have increased or become too large, it is necessary to take out all the water plants together with the soil from the pot, separate the water plant from the soil, and plant the desired water plant again in the pot.

In the method of winding the lead plate, not only the root portion of the aquatic plant is easily damaged during winding, but also the root part is covered with the lead plate, so that the growth of the aquatic plant is suppressed. In addition, the wound lead plate may be exposed from the surface layer of the bottom sand, which deteriorates the atmosphere in the water tank.

The present invention has been devised to solve such a problem, and by reliably holding the roots of water plants downward, it is possible to maintain a good atmosphere in the water tank and The purpose is to simplify the work of fixing water plants to sand.

[0008]

Means for Solving the Problems The aquatic plant fixing device for an ornamental aquarium of the present invention, in order to achieve its object, fixes the root of the aquatic plant by entanglement with fibers, sandwiching by an elastic body, or the like,
The aquatic plant is made to stand up in the water, and the fixture itself is hidden inside the bottom sand.

The first aquatic plant fixing device is characterized by being composed of a severable laminate in which a culture soil is sandwiched between a non-woven fabric layer through which a root part of aquatic plants is inserted and a lower non-woven fabric layer. The second aquatic plant fixing tool includes a sponge body having a cavity at the bottom and a planting hole portion formed on a main surface thereof, and a root fixing tool inserted into the cavity from the planting hole portion. The fixture is characterized in that it is provided with a protrusion for fixing the root part of the aquatic plant. The third aquatic plant fixing device includes a sponge body having a V-shaped groove formed on the front surface side, and an inverted conical root fixing device mounted in the V-shaped groove. It is characterized in that a protrusion for fixing the portion is provided. The fourth aquatic plant fixing device includes a box-shaped fixing device main body, a slider movably attached to the fixing device main body, and a sponge inserted into the fixing device main body. It is characterized in that the root part of the aquatic plant inserted inside is sandwiched between the end surface of the slider and the side wall of the fixture body.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. Example 1 In this example, as shown in FIG. 1, a laminated body 10 in which a culture soil 13 is sandwiched between nonwoven fabric layers 11 and 12 is used. The non-woven fabric layers 11 and 12 are made of felt-like chemical fibers having excellent water resistance. For the culture soil 13, for example, river sand mixed with appropriate nutrients is used.

The specific gravity of the laminate 10 is such that the nonwoven fabric layers 11 and 12 are
By adjusting the ratio of the culture soil 13 to the water, it is set to an appropriate value larger than water. Upper and lower non-woven fabric layers 11,
12 are connected by an appropriate connecting portion 14 so as not to be separated from each other. The connecting portion 14 sandwiches the culture soil 13 between the non-woven fabric layer 11 and the non-woven fabric layer 12 and then,
It is formed by a needling that reciprocates between 1 and the nonwoven fabric layer 12.

Water plants 15 and 16 to be placed in an aquarium
Is inserted into the culture soil 13 through the nonwoven fabric layer 11 of the laminate 10. At this time, the roots 15a of the aquatic plants 15 and 16,
Since the fibers 16a are intertwined with the fibers of the non-woven fabric layer 11, the inserted water plants 15, 16 are securely fixed to the laminate 10. In addition, the aquatic plants 15 and 16 grown by the nutrients supplied from the culture soil 13 extend roots deep inside the nonwoven fabric layers 11 and 12 and are integrated with the laminated body 10.

In order to facilitate the insertion of the aquatic plants 15, 16, it is preferable to make a notch 17 in the upper nonwoven fabric layer 11 as shown in FIG. When the root portion of the aquatic plant 15 is pressed against the non-woven fabric layer 11 where the notch 17 is formed, the notch 17 is opened as shown in FIG. 2B, and the root 15 a of the aquatic plant 15 reaches the culture soil 13. Then, when the force of pushing the aquatic plant 15 is removed, the root of the aquatic plant 15 is sandwiched by the fibers of the non-woven fabric layer 11 by the restoring force F that causes the nonwoven fabric layer 11 to return to its original shape.

Laminated body 10 into which aquatic plants 15 and 16 are inserted
Can be placed as is on the bottom of the aquarium. Then, as shown in FIG. 1, river sand is sprinkled on the upper surface of the laminated body 10 to form the surface layer 18. By this, the non-woven fabric 11
A natural atmosphere is created without exposing.

If the specific gravity of the laminated body 10 is small and there is a risk of floating, a thin metal plate 19 such as a lead plate is stacked on the laminated body 10. In addition, when the layered product 10 into which the aquatic plants 15 and 16 are inserted is placed in a culture tank and held until the aquatic plants 15 and 16 grow to a predetermined size and then transferred to an ornamental aquarium, the aquatic plants 15 and 16 are Securely fixed.

The laminate 10 can be easily cut with scissors or a cutter. Therefore, in consideration of the relationship with the accessories arranged inside the ornamental water tank, it can be cut into an appropriate size for use. For example, it is advantageous to carry out rooting of aquatic plants 15 and 16 on a laminated body 10 having a large area in a culture tank, cut the laminated body 10 to a required size, and arrange the laminated body 10 inside an ornamental water tank. is there. At this time, since the aquatic plants 15 and 16 are transferred with the roots 15a and 16a being integrated with the culture soil 13 or the nonwoven fabric layers 11 and 12, the aquatic plants 15 and 1 transferred to the ornamental aquarium are performed.
The growth of 6 is also going well.

Example 2 In this example, a sponge body 20 having the shape shown in FIG. 3 was used. The sponge body 20 has a plurality of ribs 20a protruding downward and adjacent ribs 20a.
A cavity 20b is formed between a and 20a. Further, a planting hole 20d facing the cavity 20b is formed on the main surface 20c of the sponge body 20.

The aquatic plant 21 placed in the aquarium has a root portion 21a.
After inserting the root fixing device 22, the planting hole 20d
Plugged into. The root fixing tool 22 has a mesh-shaped main body 22a formed in a cylindrical shape, and a plurality of pressing protrusions 22b project from the circumferential direction in an upper opening of the mesh-shaped main body 22a. The pressing protrusions 22b may be provided in a plurality of steps in the height direction of the mesh body 22a. The height of the reticulated body 22a is set to be slightly higher than that of the cavity 20b formed in the lower portion of the sponge body 20 so that the top of the reticulated body 22a is located at the middle portion in the thickness direction of the main surface 20c.

A pressing protrusion 23 protruding inward from the upper opening
In addition to b, it is also possible to use a root fixing tool 23 having a locking projection 23c protruding outward at a slightly upward angle. When the root fixing tool 23 is inserted into the planting hole portion 20d of the sponge body 20 placed on the bottom plate 24 of the water tank, the locking projection 23c pierces the inner circumferential surface of the planting hole portion 22d, so that the sponge is sponged. It is securely held in a position below the body 20.

Further, the fertilizer pot 25 can be detachably attached to the lower portion of the root fixture 23. The fertilizer pot 25 has a structure in which a net-like main body 25b is raised from the peripheral edge of a tray 25a containing an appropriate fertilizer.
Then, the fertilizer pot 25 is attached to the root fixture 23 by hooking the upper end of the reticulated body 25b on the lower portion of the reticulated body 23c.

Instead of using the fertilizer pot 25, for example, a starchy film 26 laid on the bottom plate 24 of the aquarium may be used as a nutrient supply source for the aquatic plant 21. In FIG. 3A, the starch film 26 is shown laid on the entire surface of the bottom plate 24. However, the starch film 26 is cut into small pieces and mixed with the soil 27, or the bottom plate corresponding to the cavity 20b is cut. You may arrange | position on 24.

The aquatic plant 21 has its root portion inserted into the upper opening of the net body 22a and is pushed downward. When the downward force is released, the root portion of the aquatic plant 21 is clamped by the restoring force of the pressing protrusion 22b to restore the original shape. At this time, in the root fixing tool 22 in which the pressing projections 22b are provided in multiple stages in the height direction of the net-like main body 22a, the roots are clamped at a number of places, so that the aquatic plant 21 is reliably fixed.

As shown in FIG. 3 (b), the root fixture 22 having the water plant 21 attached thereto is inserted into the cavity 20b from the planting hole 20d of the sponge body 20. The soil 27 filled in the cavity 20b as the root fixture 22 is inserted.
Enter the inside of the mesh of the mesh body 22a,
Fill around 1a.

After the planting work of the aquatic plant 21, river sand is sprinkled on the sponge body 20 to form the surface layer 28. The weight of the surface layer 28 prevents the sponge body 20 from rising. Alternatively, a weight such as lead may be attached to an appropriate portion of the sponge body 20 to increase the specific gravity of the sponge body 20. In this case, since the sponge body 20 itself sinks in water, the amount of river sand scattered as the surface layer 28 can be reduced.

In this way, the aquatic plant 21 has a root portion 21a.
Is fixed by the root fixing device 22, and the bottom plate 24 of the aquarium is well-positioned.
Placed on top. Further, in the case of incorporating the fertilizer pot 25 and the starchy film 26, the growth of the aquatic plant 21 is promoted. Then, the sponge body 20 and the root fixing device 22
Etc. are covered with the surface layer 28 and do not deteriorate the atmosphere inside the water tank. The sponge body 20 is cut into an appropriate size and used in the same manner as the laminated body 10 of the first embodiment.

Example 3 In this example, a sponge body having a plurality of V-shaped grooves as shown in FIG. 4 was used. The sponge body 30 is formed with a plurality of V-shaped grooves 31a, 31b ... Which extend in one direction. V-shaped groove 31
Through holes 33 reaching the fertilizer pack 32 attached to the back surface of the sponge body 30 are provided at appropriate intervals at the bottom of a, 31b, ....

The aquatic plants placed in the aquarium are fixed at the root 34
Or after the root is fixedly supported by 35, V-shaped grooves 31a, 31
planted in b ... The root fixtures 34 and 35 are
Locking protrusions 34 having reverse conical net bodies 34a, 35a corresponding to the cross-sectional shapes of the V-shaped grooves 31a, 31b ... And piercing the slopes of the V-shaped grooves 31a, 31b.
b and 35b project from the peripheral surfaces of the mesh bodies 34a and 35a.

In the root fixing member 34, a plurality of pressing protrusions 34c protruding in the center direction are provided at equal intervals in the circumferential direction of the open end of the mesh body 34a. Pressing protrusion 34c
Holds the root 36a of the aquatic plant 36 in the same manner as the pressing protrusions 22b and 23b of the root fixing tools 22 and 23 in the second embodiment.

In the root fixing device 35, pressing protrusions 35c having spring elasticity are attached so as to be undulated at equal intervals in the circumferential direction of the open end of the net-like body 35a. When fixing the root of the water plant 37 to the root fixture 35,
Open c and put the root 37 of aquatic plant 37 inside the mesh body 35a.
After inserting a, the force applied to the pressing protrusion 35c is released. The pressing protrusion 35c has its tip end rotated in the center direction by elastic restoring force, and as shown in FIG.
Hold a.

The root fixing members 34, 35 which fix the roots 36a, 37a of the aquatic plants 36, 37 are pushed into the V-shaped grooves 31a, 31b ... Of the sponge body 30. When the force for pushing the root fixing devices 34, 35 is released, the locking projections 34b, 35b become V-shaped grooves 31a, 31b by the restoring force of the sponge body 30 and the mesh bodies 34a, 35a that are compressed.
Stick into the slope of ... As a result, the root fixing device 3
4, 35 are held at predetermined positions of the V-shaped grooves 31a, 31b ....

The sponge body 30 with the root fixing devices 34 and 35 attached is laid on the bottom of the water tank, and river sand or the like is sprinkled on the sponge body 30 to form the surface layer 38. Then, water is poured into the aquarium and aquatic organisms are put therein. The aquatic plants 36, 37 receive nutrients from the fertilizer pack 32 below the sponge body 30 and grow smoothly. The roots of aquatic plants 36 and 37 that grow with growth are
From the mesh of the mesh bodies 34a, 35a, the V-shaped groove 31a,
Since it extends in the longitudinal direction of 31b ..., problems such as root rot caused by nodulation of grown roots do not occur.

Example 4 The aquatic plants can be arranged in a water tank by fixing one or several roots without using a laminated body having a large area as in Examples 1 to 3. .. For example, as shown in FIG. 5, a root fixing tool 40 that can fix one or two aquatic plants is used.

The root fixing member 40 has a fixing member main body 41 having a substantially rectangular parallelepiped shape, and a guide groove 42 is formed on a side surface thereof. Then, the inverted U-shaped slider 43 is bridged from the guide groove 42 on one side surface to the guide groove 42 on the opposite side surface via the upper surface of the fixture main body 41, whereby the slider 43 in FIG. It can be slid to the left and right.

On the upper surface of the fixture body 41, the slider 4
An opening 44 is formed along the longitudinal direction of the hole 3. From this opening 44, as shown in FIG.
1 is filled with fertilizer 45, and a sponge 46 is inserted thereon. The sponge 46 is provided with a notch 46a.

After inserting the root 47a of the aquatic plant 47 into the notch 46a, the slider 43 is slid to the right in FIG.
And the side surface 41a of the fixture main body 41. As a result, the root 47a of the aquatic plant 47 is fixed to the root fixture 4.
It is fixed at 0.

After mounting the root fixing device 40 with the water grass 47 mounted on the bottom plate 48 of the water tank, the bottom sand is sprinkled on the bottom plate 48 to form a sand layer 49. The sand layer 49 is provided with a thickness that covers the upper surface of the root fixture 40. As a result, the atmosphere inside the water tank becomes close to nature, and the root 47a is pressed down even by the bottom sand, so that the water grass 47 is prevented from rising. Note that the root fixture 40 may be embedded in the sand layer 49 after the sand layer 49 having a predetermined thickness is provided on the bottom plate 48.

As the device for fixing the roots of aquatic plants, other various shapes are used. FIG. 6 shows some examples. The root fixture 50 of FIG. 6 (a) has a plurality of leg portions 50b attached to a mesh body 50a,
The root of the aquatic plant 50c is fixed to the net-like main body 50a with an elastic body such as a rubber band 50d.

The root fixing tool 51 shown in FIG.
A rod-shaped body 51b is raised from 1a, and wires 51c are attached at appropriate intervals in the longitudinal direction of the rod-shaped body 51b. After binding the roots of the water plants with the wires 51c, the pedestal 51a is embedded in the sand layer. The rod-shaped body 51b acts as a pillar that keeps the aquatic plant vertically in the water.

The root fixture 52 shown in FIG. 6 (c) comprises a rod-shaped body 52b extending from a tubular mesh body 52a, and an installation portion 52c formed at the lower end of the rod-shaped body 52b. A plurality of locking protrusions 52d protruding in the center direction are provided in the upper opening of the mesh body 52a.
Is provided. The root part of the aquatic plant inserted into the internal space of the mesh body 52a is clamped by the elastic restoring force of the locking projection 52d.

The root fixture 53 shown in FIG. 6 (d) has a semi-cylindrical net-like main body 53a, and pressing pieces 53b, 53c which can be opened and closed.
Is attached to form a cylindrical shape as a whole.
The pressing pieces 53b and 53c elastically rotate about the hinges 53d and 53e. Hinge 53 open
After inserting the root of the aquatic plant into the cylindrical space formed by d, 53e and the mesh body 53a, the pressing pieces 53b, 53
Apply force to the side of c. As a result, the pressing pieces 53b, 5
3c is elastically pressed against the mesh body 53a side around the hinges 53d and 53e as shown by the arrow, and the root of the aquatic plant is clamped between the mesh body 53a and the pressing pieces 53b and 53c.

The root fixing tool 54 shown in FIG.
The L-shaped net 54b is attached to a. L-shaped net 54b
In the steady state, the upper end edge is in contact with or close to the net body 54a, and the root insertion opening 54c between the net body 54a and the net body 54a is opened by elastic deformation. Further, the net 54a is attached with a leg portion 54d extending downward, and an installation portion 54e is provided at a lower end of the leg portion 54d. When the legs 54d and the installation portion 54e are made of wire, it becomes easy to embed the root fixture 54 in the sand layer.

For example, the aquatic plant 54f is attached to the root insertion port 54c.
As shown in FIG. 6 (f), the root fixture 54 sandwiched between the sand layer 5 and the mesh main body 54a is hidden by the sand layer 54g.
Embedded in 4g. At this time, the embedded state of the root fixture 54 is stabilized by the horizontally extending installation portion 54e. Therefore, even if the surface layer of the sand layer 54g flies up to some extent as aquatic animals move, the aquatic plant 54f does not fall.

When planting aquatic plants in the bottom sand of an aquarium, it may be necessary to apply fertilizer in order to promote their growth. For simple fertilization, the means shown in FIG. 7 can be adopted. That is, when fertilizing the aquatic plant 62 planted in the bottom sand 61, the fertilizer supply pipe 63 is used.
The fertilizer supply pipe 63 has a length such that the upper end thereof projects from the water surface 64a of the water layer 64 when the lower end is pierced into the bottom sand 61.

With the fertilizer supply pipe 63 piercing the bottom sand 61, the fertilizer 65 is pushed through the upper end opening 63a on the water surface 64a. As the fertilizer 65, for example, one contained in a capsule 66 can be used. It is preferable that the capsule 66 has a large number of holes 66a on its peripheral surface so that the fertilizer 65 contained therein flows out or dissolves into the bottom sand 61 or the water layer 64 for a long time. Alternatively, the capsule 66 can be made of a porous material or a water-soluble material.

As the capsule 66 which can be repeatedly used,
For example, a cylinder 66b made of an insoluble material and having a lid 66c attached thereto is used. This capsule 66 is inserted into the fertilizer supply pipe 63, and the inside of the fertilizer supply pipe 63 is pushed forward by an appropriate push rod, and the capsule 6 is placed on the bottom sand 61.
Stick 6 As a push rod, the lid 66c of the capsule 66
If one with a sharp tip that sticks into the bottom is used, the bottom sand 61
When the push rod is pulled out after the capsule 66 is pierced into the capsule 66, the lid 66c is removed from the capsule 66,
As shown in (c), the upper end opening 66d of the capsule 66 is released.

Such fertilizing means is also applied to injection of a chemical solution for the purpose of exterminating pathogenic bacteria. In this case, the chemical solution gradually dissolves from the capsule 66 into the bottom sand 61 and the water layer 64,
The effectiveness of the drug solution is secured for a long period of time. for that reason,
The inside of the aquarium is kept in good hygiene, and aquatic life can be maintained for a long period of time.

[0047]

As described above, according to the present invention, the roots of water plants placed in the aquarium are firmly fixed,
Even if the surface layer of the bottom sand is rolled up due to movement of aquatic organisms or water exchange, floating of aquatic plants is prevented. Planting aquatic plants on the bottom sand is also easy. Moreover, the aquatic plant fixing device is embedded in the bottom sand without giving an uncomfortable feeling. Therefore, the inside of the water tank can be maintained in a natural state for a long period of time, and the observer is not given a bad impression.
