Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bench for plant cultivation using movable shelves in which shelves on which cultivation containers are placed are movable in order to make effective use in greenhouses and vinyl greenhouses.

[0002]

2. Description of the Related Art As a bench for plant cultivation of this type, for example, as shown in FIG.
A beam 101 which is laid across the upper part of the
There is known one having a roller 102 which is spanned between beams 101 arranged to face each other and rolls on the beam 101, and a movable shelf 103 which is placed on the roller 102. With such a configuration, even if the movable shelves 103 adjacent to each other are installed in the greenhouse so that they are in contact with each other, an operator can push the movable shelves 103 to move the rollers 102 on each other as long as the passage width for one place is secured. If you can secure a passage in another place,
It is possible to increase the effective cultivation area of the greenhouse without hindering the cultivation work.

[0003]

As such a movable shelf, a plate-like body is usually used for mounting a cultivation container. However, the use of the plate-shaped body is heavy, so that the installation work on the site is difficult and also inconvenient when it is transported to the site. Also, when moving the movable shelf on the roller, the heavier the weight, the more labor the operator needs to move.

In order to solve this, it is conceivable to reduce the weight of the movable shelves. For example, a pipe material that is simply bent into a square shape is used, and a cultivation container is placed on it. It is conceivable to dispose a net member or the like. However, if the pipe material is simply processed into a substantially rectangular shape, the portion that comes into contact with the roller becomes extremely small, that is, if the frictional force is small and the base is slightly inclined, the movable shelf can be moved in either direction. When moved, it may not stop and may easily return in the opposite direction, or it may shift along the axial direction of the roller during movement. It may be possible to provide multiple pipes for reinforcement along the moving direction of the movable shelf, but in that case, there are many connection points by welding etc. to the pipe material bent into a substantially rectangular shape, and the processing process is complicated. The problem is that

The present invention has been made in order to solve the above-mentioned problems, and aims to reduce the weight of a movable shelf and to install the movable shelf.
(EN) Provided is a plant cultivation bench, which can facilitate the transfer work, can minimize the backward movement of the movable shelf after the movement and the deviation during the movement, and does not complicate the processing process. With the goal.

[0006]

In order to achieve the above object, a plant cultivation bench of the present invention is constructed by combining pipe materials, and has a base having a beam which is supported by legs and assembled in a substantially square shape in a plane. And a roller that is laid over a pair of opposing two sides that form the beam of the base and is rollably arranged between stoppers provided at both ends of the two sides, and on the roller. In a plant cultivation bench having a movable shelf for placing the cultivation container, which is positioned, the movable shelf is processed into a substantially pipe-shaped first pipe material processed into a substantially square shape, Between a pair of two opposing sides of the first pipe member,
And a second pipe member arranged so that the vicinity of the top is in contact with the substantially central part of one side and both hem parts are in contact with the side opposite to the one side, and constitutes a first pipe member. The other two opposite sides and the two inclined sides between the top and the bottom of the second pipe member are in contact with the roller.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the embodiments shown in the drawings. 1 to 4 show an embodiment of the present invention, in which 1 denotes a plant cultivation bench of the present embodiment, which comprises a base 2, rollers 3, and a movable shelf 4.

The base 2 is composed of a beam 21 and legs 22 and 23. In this embodiment, the beams 21 are movable shelves 4 to be described later.
The two long pipe members 21a and 21b and the two short pipe members 21c and 21d each having a length capable of being mounted on the roller 3 by connecting two of them are arranged to face each other, and the leg portion 2
2 and 23 are connected in the vicinity of the upper part and are formed in a substantially rectangular shape in a plane. The beam 21 may be formed by bending one pipe material into a substantially rectangular shape.

The legs 22 and 23 are each formed by bending one pipe material, and the beam 2 assembled into a substantially rectangular shape.
Vertical parts 22a, 22b, 23 fixed to the respective corners
a, 23b and a pair of vertical portions 22a, 22b or 23
It is formed in a mountain shape between a and 23b, and each top portion is constituted by reinforcing portions 22c and 23c that are connected and fixed by abutting the substantially central portions of the short pipe members 21c and 21d of the beam 21.
As the legs 22 and 23, it is needless to say that a simple rod-shaped member may be attached so as to stand substantially perpendicularly to the ground, but in terms of strength, the reinforcement 2 as in this embodiment.
Structures having 2c, 23c are preferred.

Here, the beam 21 has the leg portion 2 as described above.
Vertical parts 22a, 22b, 23a, 23
Since it is connected and fixed in the vicinity of the upper part of b, specifically, at a position slightly shifted downward from the upper end, the beam 2 is connected to the upper end of each vertical part.
The space between the connecting portion 1 and the connection portion 1 projects upward from the beam 21. In this embodiment, the protrusions are provided on the two opposite sides of the pair, that is, on both ends of each of the short pipe members 21c and 21d, and the stopper 2 that restricts the rolling range of the roller 3 is provided.
It is used as 2d and 23d. The legs 22 and 2
It goes without saying that a member different from 3 may be attached as a stopper.

The roller 3 is composed of a pair of opposing two sides of the beam 21, that is, a pipe material or a cylindrical rod member having a length that can be bridged between the short pipe materials 21c and 21d. In the embodiment, two are provided as shown in FIG. 1, but three or more may be provided.

The movable shelf 4, as shown in FIGS. 1 and 2,
It is configured to have a first pipe member 41 formed by combining two L-shaped pipes. Specifically, the first pipe member 41 is assembled so that one long side portion of each L-shaped pipe is fitted and connected to the other short side portion, and is formed in a generally rectangular plane as a whole. There is. The size is not particularly limited, but at least the length of the opposing two sides 41c, 41d parallel to the moving direction of the movable shelf 4 is a short pipe of the beam 21 of the base 2 which is also formed in a substantially rectangular shape. It is necessary to form the members 21c and 21d to be longer than the length of the members 21c and 21d by at least the moving distance D shown in FIG. This is because the movable shelf 4 is moved to secure a working passage between the movable shelf 4 and another adjacent movable shelf.

Although four rod-shaped pipes may be connected to each other, two L-shaped pipes may be used as in this embodiment or one long pipe may be used for ease of processing. The pipe may be bent into a substantially rectangular shape.

Further, the movable shelf 4 is such a first pipe member 4
Second arranged in a substantially rectangular space formed by 1
The pipe material 42 of FIG. Specifically, the second pipe member 42 is bent and formed into a substantially chevron shape in a plane as a whole, and is opposed to each other along the moving direction of the movable shelf 4 among the four sides forming the first pipe member 41. A pair of opposite sides 41
Between a and 41b, the vicinity of the top portion 42a abuts on the inside of the substantially central portion of one side 41a of the two opposite sides and is fixed by a bolt, and the two hem portions 42b and 42c are opposed to each other (the other side). ) 41b is abutted on the inside and fixed by bolts. Therefore, in the second pipe material 42, between the vicinity of the top portion 42a and the hem portions 42b, 42c,
Two inclined sides 42d and 42e will be formed.
It should be noted that the top pipe portion 42a of the second pipe member 42 and both hem portions 42b, 42c are formed on the opposite two sides 41 of the first pipe member 41.
The second pipe member 4 is brought into contact with the insides of c and 41d.
When the diameter of 2 and the diameter of the first pipe material 41 are made substantially the same, the short pipe material 41 that constitutes the first pipe material 41
c, 41d and lower parts of inclined sides 42d, 42e are all rollers
This is to make contact with.

When the vicinity of the top portion 42a of the second pipe member 42 is brought into contact with the substantially central portion of one side 41a of the first pipe member 41 and both hem portions 42b and 42c are brought into contact with the inside of the other side 41b, the top portion 42a is formed. Two L-shaped members that are fitted and connected can be formed by connecting and fixing one hem portion 42b to the other L-shaped pipe in the vicinity to one L-shaped pipe that constitutes the first pipe member 41. It is also possible to prevent the mold pipe from coming off naturally due to long-term use.

In the present embodiment, two such movable shelves 4 are used by being connected, but the sides 41d and 41c adjacent to each other are used.
A long member 5 is interposed between them, and is connected and fixed by bolts and nuts. The elongated member 5 has two projecting pieces 51, 52 protruding downward and provided at predetermined intervals.
Is provided. The projecting pieces 51, 52 are provided with two rollers 3, 3 arranged outside the both.
It comes into contact with and plays a function of rolling the rollers 3, 3.
In addition, in this embodiment, since the two movable shelves 4 and 4 are connected, the elongated member 5 is arranged between them.
The movable shelves 4 may be arranged along the outside or inside of the other two opposite sides 41c and 41d. Further, as described above, instead of separately disposing the long member 5 having the projecting pieces 51 and 52, two elongated members 5 are provided at appropriate positions of the first pipe member 41 or the second pipe member 42 at predetermined intervals. You may provide a protrusion.

The plant cultivation bench 1 of this embodiment is used as follows. First, the base 2 is placed in a greenhouse or the like. Two
The rollers 3 and 3 are arranged on the short pipe members 21c and 21d of the beam 21 forming the base 2. Next, the two movable shelves 4 and 4 connected via the elongated member 5 are placed so that the rollers 3 are located outside the protrusions 51 and 52 of the elongated member 5. Although not shown, a net member or the like is further placed on the movable shelf 4, and a cultivation container in which a plant is planted is placed thereon. Further, as shown in FIG. 4, the number of the benches 1 for plant cultivation is set to the moving direction X of the movable shelf 4,
If a space corresponding to the movement distance D of one movable shelf 4 can be secured along the Y in the greenhouse, a large number of movable shelves 4 adjacent to each other along the movement directions X and Y should be arranged so as to come into contact with each other. You can

When carrying out the work, the necessary movable shelves 4 are moved, for example, in the X direction. Following the movement of the movable shelf 4, the rollers 3, 3 also roll in the X direction. Then, when the roller 3 comes into contact with the stopper 22d, the movable shelf 4 stops moving. As a result, it is possible to secure as many passages as the movement distance D. Therefore, as described above, the moving direction X,
Even if a large number of movable shelves 4 adjacent to each other along Y are brought into contact with each other, there is no hindrance in the cultivation work. In addition,
When the movable shelves 4 are moved in the opposite direction Y, as shown by imaginary lines in FIG. 3, the rollers 3, 3 also roll in the Y direction, and when the other roller 3 abuts the stopper 22d, the movable shelf 4 moves. Of course, it is possible to secure a passage at a position opposite to the above with the movable shelf 4 interposed therebetween.

When moving the movable shelf 4, the movable shelf 4 is composed of only two sets of members, that is, the first pipe member 41 and the second pipe member 42.
With respect to the two opposite sides 41c, 41 of the first pipe member 41.
d and the inclined sides 42d and 42e of the second pipe member 42 are in contact with each other. Moreover, since the inclined sides 42d and 42e of the second pipe member 42 are in contact with each other, for example,
Compared with the case where two pipe materials are arranged in parallel with the pipe materials 41c and 41d, the contact area with the roller 3 is large. That is, since the contact friction with the roller 3 can be secured to some extent despite being the minimum required member, even if the base 2 is installed with a slight inclination, the movable shelf 4 can be prevented from moving to some extent. . Further, for the same reason, when the movable shelf 4 is moved, even if the roller 3 is unevenly moved in the axial direction (thrust direction), the two opposite sides 41 of the first pipe member 41 are moved.
Compared to the case where two pipe materials are arranged in parallel with c and 41d, the number is small.

Moreover, since the movable shelf 4 is composed of the minimum necessary members, it is possible to easily carry out transportation to the site, installation work, and moving work of the movable shelf 4.

The mobile bench for plant cultivation of the present invention is not limited to the above embodiment. For example,
Among the elongated members 5 used in the above-mentioned examples, the protrusions 51,
An uneven portion is formed on the outer side of 52, that is, on the lower edge of the portion that abuts against the rollers 3 and 3 to increase the contact friction with the rollers 3 and 3 to further reduce unnecessary natural movement and unbalanced movement. You can also When the long member is not used, the same effect can be obtained by forming these uneven portions on the outer sides of the projecting pieces provided on the first pipe member 41 or the second pipe member 42 that form the movable shelf 4. Can be demonstrated.

Further, the leg portions 22 and 23 forming the base 2 may be formed so as to be foldable toward the beam 21. As a result, the transportation work and the like becomes simpler. In addition, the legs 22,
An adjuster for height adjustment may be provided at the lower end of each vertical portion 22a, 22b, 23a, 23b of 23.

Further, in the above-described embodiment, the two movable shelves 4 and 4 connected to each other are placed on one base 2. However, it goes without saying that a larger number of movable shelves 4 may be connected. is there. In this case, a plurality of the bases 2 shown in FIG. 1 may be arranged to support a large number of movable shelves 4, but in the configuration shown in FIG. 1, the long pipe members 21a and 21b are connected to the vertical portion 2 of the leg portion 22.
2a, 22b is used to form a base that is projected along the connecting direction (longitudinal direction) (not shown), the bases are arranged at both ends in the longitudinal direction, and the bases are arranged between the opposing protruding portions of both bases. It is also possible to connect a plurality of pipe members (not shown) and further connect supporting legs (not shown) to the pipe members at appropriate positions.

[0024]

According to the bench for plant cultivation of the present invention, since the movable shelf is made of pipe material, it is lightweight,
Installation of movable shelves and transportation work can be facilitated. In addition, since the inclined side of the second pipe material forming the movable shelf is in contact with the roller, even though the minimum necessary pipe material is used, the movable shelf moves backward or is moving. It is possible to reduce the deviation. Further, since the pipe materials are simply connected and the number of parts is small, the working operation is easy.
