Abstract

PROBLEM TO BE SOLVED: To obtain strut structure for pots, which is readily unfolded, stabilized in a unfolded state and has further reduced bulk volume when folded. SOLUTION: A first connection piece 16a to a first connection piece 16d are fixed to each tip of four struts 13a-13d constituting strut structure 11 of a pot and the pieces are rotatably connected by a first connection rod 15a to a first connection rod 15d. Similarly, a second connection piece 19a to a second connection piece 19d and a third connection piece 22a to a third connection piece 22d are fixed at the middle positions and the lower positions of the strut 13a to the strut 13d. A second connection rod 18a to a second connection rod 18d and a third connection rod 21a to a third connection rod 21d are each rotatably fixed to each of the connection pieces. Consequently, when pairs of the struts facing each other are mutually moved in the opposite directions, the whole struts are folded in a bar state.

And are all set to be the same.

Therefore, in the strut structure 11 of the flowerpot according to this embodiment, each of the strut 13a to the strut 13d is arranged so as to spread slightly from the lower end toward the upper end. This makes the pillar structure of the flowerpot 11
When installed in a flower pot (not shown), the appearance impression when using the pillar structure 11 of the flower pot is improved.

Next, a description will be given of a change when the pillar structure 11 of the flower pot shown in FIG. 1 is folded from the expanded state.

FIG. 4 is a perspective view showing a state where the support column is folded from the state shown in FIG. 1, and FIG. 5 is a perspective view showing a state where the support column is completely folded.

Referring to FIG. 4, a force is applied to the supporting columns 13a and 13c facing each other from the state shown in FIG. 1 so as to move them upward in the axial direction. On the other hand, a force is applied to the other opposing columns 13b and 13d so as to move them downward in the axial direction. At this time, as described above, the first connecting rod 15, the second connecting rod 18, and the third connecting rod 21 have the first connecting piece 16a to the first connecting piece 16d and the second connecting piece 19a to the second connecting piece 19 respectively.
d and the third connecting piece 22a to the third connecting piece 22d are rotatably connected.

Therefore, with respect to the movement in the direction of the arrow generated in each of the columns 13a to 13d, a force that obstructs the movement does not occur, and the whole is deformed as shown in the figure. That is,
The connection state of the first connecting rod 15a and the first connecting rod 15d changes with the first connecting piece 16a, the first connecting piece 16c, and the first connecting piece 16d so that they form a V shape.

Similarly, the first connecting rod 15b and the first connecting rod 1
These connection states change so that 5c also has a V shape. The connection states of the second connecting rod 18 and the third connecting rod 21 also change. Then, each of the columns 13a to 13d moves as they move in the axial direction.
The first connecting rod 15, the second connecting rod 18, and the third connecting rod 21 are moved so as to approach each other. When the columns 13a to 13d further move to their final positions, the column structure 11 of the flowerpot changes to the state shown in FIG. FIG. 6 is an enlarged perspective view showing the uppermost state of the folded state shown in FIG.

When the strut structure 11 of the flowerpot is completely folded as shown in these figures, the strut 13a and the strut 13c come close to each other. Along with this, the first connection piece 1 attached to the tip of the column 13a
Each of the first connecting rod 15a and the first connecting rod 15b connected to 6a extends downward along the support column 13a.

Similarly, each of the first connecting rod 15c and the first connecting rod 15d connected to the first connecting piece 16b attached to the tip of the column 13c also extends downward along the column 13c. Then, the first connecting rod 15a and the first connecting rod 15d
The column 13d connected to the lower side of the column and the column 13b connected to the lower side of the first coupling rod 15b and the first coupling rod 15c are also close to each other and located along the columns 13a and 13c.

That is, from that position, each of the columns 13a and 13d extends downward while being in contact with the columns 13a and 13c. And the second connecting rod 1
8a to the second connecting rod 18d also include the columns 13a to 1
It moves so as to extend downward along each of 3d.
Similarly, each of the third connecting rod 21a to the third connecting rod 21d also
It moves so as to extend downward along each of the columns 13a to 13d.

When the strut structure 11 of the flower pot is completely folded in this manner, the strut 13a to the strut 13d are brought close to each other and integrated, and the first connecting rods 15 and 15 are formed around them.
Each of the second connecting rod 18 and the third connecting rod 21 moves along. Therefore, the bulk capacity of the pillar structure 11 of the flowerpot in the folded state is further reduced. That is, the occupied volume of the strut structure during storage and transfer in this state is extremely small, and the folded state is efficient.

The expansion from this state to the use state shown in FIG. 1 is carried out in the direction opposite to the direction of the arrow shown in FIG.
It suffices to apply a force to each of the columns 13d. As a result, the state of FIG. 5 immediately changes to the state of FIG. Since the lower ends of the columns 13a to 13d are in a state of being inserted and fixed in the flower pot as in the conventional example of FIG. 7, there is no possibility that the columns 13a to 13d will move in the axial direction. Absent. Therefore, the strut structure 11 of the flowerpot does not change to the state shown in FIG. 4, and it is possible to maintain a stable expanded state.

In the above embodiment, three sets of the connecting piece and the connecting rod are provided for the support column, but the same effect can be obtained if at least one set is provided.

Further, in the above embodiment, the number of columns is four, but the number of columns may be (4 + 2 × n), where n is a natural number. In this case, when a force is applied to one of the columns and the other of the columns of every other column in directions opposite to each other in their axial directions, they move relatively while approaching each other.
Then, it becomes possible to fold on the columns in a state in which each of the connecting rods is along.

Further, in the above embodiment, the rotating structure is formed by the projection of the connecting piece and the ring of the connecting rod, but it goes without saying that a rotating structure of other structure may be used. Yes. Further, the protrusion may be provided on the connecting rod and the ring body may be provided on the connection piece.

Further, in the above embodiment, the cap is used as the fixing means for the uppermost connection piece,
It goes without saying that a band-shaped fixing member having a U-shape in plan view at another position may be used instead.
