Description

  The present invention relates to a rotary flower pot placement device that can be rotated so that potted plants are uniformly exposed to light.

  In general, plants have the property that the tip part or the flower or leaf part is directed to receive light.For example, if a potted plant for viewing is left on the window or outdoors, the nature and the flower or leaf part are unidirectional. It turns away, and the shape is broken and it looks bad. For this reason, by changing the direction of potted plants at appropriate time intervals, it is possible to prevent the flowers and leaves from extending in the direction of light and to grow evenly as a whole. However, an apparatus for automatically changing the orientation of the flower pot by a simple means has not been developed yet, and it is performed by a method of lifting the pot manually and irregularly changing the orientation.

  As a conventional technique related to flower pots, the main body part of the flower pot and the water tray on the lower side thereof are rotated relative to each other at a certain angle to prevent the water tray from falling when the main body part is lifted. In addition, when separating the two for cleaning the water tray, it is known that the main body is rotated in the reverse direction to disengage the mutual engagement (for example, Patent Document 1). As the engaging means in this case, a plurality of irrigation protrusions projecting downward are formed on the bottom surface of the main body of the pot, and a raised portion is formed on the inner bottom surface of the water tray, and provided on the irrigation protrusion. The raised portion of the water tray is engaged with the step portion by relative rotation. In addition, all of this rotation engagement is a structure rotated manually.

  Patent Document 2 describes a bonsai mounting table that holds a bonsai placed on a table so that the bonsai can be moved up and down and rotated around a vertical axis. In this structure, the lower end of the shaft connected to the lower surface of the mounting table is inserted into the tip hollow portion of the columnar support table on the floor surface, and pins are formed in a plurality of upper and lower horizontal holes formed in the tip hollow portion of the support table. The adjusting member is inserted to support the lower end of the shaft portion. The orientation of the front position, side face position, etc. of the bonsai is changed by rotating the shaft portion around the axis with respect to the support base.

  In addition, bolts and nuts are attached to the side of a rotary table that is pivotally supported on a suitable base, and a wire is sandwiched between the bolts and nuts, and the bonsai on the rotary table is solidified with the wire. A bonsai rotary table structure is also disclosed (Patent Document 3). In this structure, when changing the orientation of the bonsai, it is not necessary to lift the bonsai by hand, and the bonsai is fixed to the rotating table with a wire. It is not.

  As mentioned above, in order to grow potted plants evenly as a whole without the flowers and leaves being biased in one direction, the potted plant should be rotated periodically to change the direction of the pot. However, in the past, the whole bowl was lifted by hand and changed its orientation. However, some foliage plants such as trees require large pots, and it is a cumbersome task to lift and rotate a heavy plant pot by hand. In particular, when the number of pots is large, it is necessary to change the orientation of a plurality of flower pots, which requires a lot of labor. For this reason, the work of changing the orientation of the flower pot tends to be negligible, and there are cases where the plants for viewing are not evenly and satisfactorily grown.

  Although the flower pot described in Patent Document 1 described above has a description of rotating the main body portion of the pot with respect to the lower water tray, this is for the attachment and detachment of the main body portion and the water tray. The purpose of this is to prevent root rot and to manage the cleaning of water trays. In addition, the bonsai mounting table of Patent Document 2 allows the mounting table installed on the floor surface via the shaft part to be adjusted with respect to the vertical position and rotated relative to the shaft part or the supporting table. Although there is a description to hold, there is no description about the means for smoothly rotating the mounting table carrying the bowl, and no mention is made of countermeasures when the bowl is increased in size and weight. Furthermore, the structure of the rotary table for bonsai in Patent Document 3 is similarly described with no specific measures to make the rotation of the table on which the bonsai is placed light and smooth, and the bonsai on the rotary table at the time of rotation is used as the rotary table. Only wire hooking means for fixing the wire is described.

  The present invention allows a large and heavy flower pot to be easily and smoothly rotated in the required direction while being placed on a mounting table without lifting it by hand, so that the tip of the plant or the flowers and leaves can be rotated in a specific direction. An object of the present invention is to provide a rotary type flower pot placing device that is not biased toward the surface.

  The present invention further allows the mounting table on which the flower pot is placed to be automatically rotated at a low speed around the vertical axis, thereby preventing the tip of the plant or the flower or leaf from being biased in a specific direction. An object of the present invention is to provide a rotary flower pot placing device.

  According to the present invention, a base having a seating surface formed on the upper part, a rotating plate pivotally supported on the seating surface of the base and configured to support a flower pot on the upper surface, and the base Means for preventing separation of the rotating plate from the table, a plurality of rolling elements interposed between the upper surface periphery of the seating surface and the lower surface periphery of the rotating plate, the upper surface of the base table, and There is provided a rotating flowerpot placing device characterized by having rolling element guide grooves formed on the lower surface of the rotating plate.

  According to one aspect of the present invention, a motor that rotationally drives the rotating plate with respect to the base is provided, and the rotating plate includes a gear formed on an outer peripheral side portion of the rotating plate and an output of the motor. It is rotationally driven by a meshing means with a gear connected to the shaft.

The present invention will now be described by way of preferred embodiments with reference to the drawings.
Example 1
Referring to FIGS. 1 and 2, a rotary flower pot mounting device 1 according to this embodiment includes a base 2 installed on the upper surface of the ground or an appropriate gantry member and having a seating surface 2a formed thereon. Have. On the upper seat surface 2a of the base 2, an annular groove 3 is formed along the outer periphery. The concave groove 3 is an arc-shaped groove as viewed in the longitudinal section of the base 2, and as will be described later, the arc-shaped concave groove 3 has a large number of rolling elements, in this embodiment, a small rolling element ( A small ball 5) is accommodated. The small sphere 5 rolls in the circumferential direction along the arcuate groove 3 and therefore the arcuate groove 3 functions as a small ball rolling groove. A bolt insertion hole 6 to be described later is formed at the center of the base 2, and a concave portion that is concentric with the bolt insertion hole 6 and has a larger diameter than the bolt insertion hole 6 at the center of the lower surface of the base, that is, the back side of the base 2 7 is formed.

  A rotating plate 8 is supported on the upper surface of the base 2 concentrically with the base 2 via small balls 5 of rolling elements. A flower pot 10 is placed on the upper surface of the rotating plate 8. In this embodiment, an annular groove 9 is formed on the lower surface of the rotating plate 8 on the outer periphery so as to face the arc-shaped groove 3 of the base 2. A large number of small spheres 5 are sandwiched between the recessed grooves 3 of the base 2 and the recessed grooves 9 on the lower surface of the rotating plate 8 and can roll in the circumferential direction along these recessed grooves 3 and 9. . When the rotating plate 8 is manually rotated with respect to the base 2, the small balls 5 are sandwiched between the concave groove 9 of the rotating plate 8 and the concave groove 3 of the base 2 and roll. In this way, a large number of small balls 5 are accommodated between the concave grooves 3 and 9 so as to be able to roll. Therefore, even if the flower pot 10 on the rotating plate 8 is large and heavy, the rotating plate 8 is extremely rotated. It is light and smooth. In this way, the flowerpot 10 can be freely changed in direction while being placed on the rotating plate 8.

  In order to prevent the rotating plate 8 from being detached from the base 2 in a state where the base 2 and the rotating plate 8 are combined, the shaft of the rotating plate 8 with respect to the base 2 is interposed between the base 2 and the rotating plate 8. A direction departure prevention means is provided. In the first embodiment, as shown in FIG. 1, a bolt insertion hole 11 is drilled at the center of the rotating plate 8, and the bolt insertion hole 6 described above is formed at the center of the base in alignment with the bolt insertion hole 11. . As described above, a recess 7 having a larger diameter than the bolt insertion hole 6 is formed on the lower surface of the base 2 concentrically with the bolt insertion hole 6. A bolt 12 is inserted from the bolt insertion hole 11 of the rotating plate 8 into the bolt insertion hole 6 of the base 2, and the outer diameter of the bolt 12 is larger than that of the bolt insertion hole 6 at the position of the large-diameter recess 7 of the base 2. A hex nut 13 is screwed. At this time, the nut 13 is screwed to such an extent that a slight gap t (FIG. 1) is generated with respect to the upper surface (recessed inner surface 7 a) of the large-diameter recess 7 of the base 2. That is, the screw 2 is screwed so that there is a slight clearance between the nut 13 and the upper inner surface 77a of the base recess 7 so that the base 12 and the rotating plate 8 are not tightened by the head 12a of the bolt 12 and the nut 13. It is worn.

  With such a configuration, when the rotary plate 8 is lifted upward with both hands, the nut 13 screwed to the tip of the bolt contacts the upper inner surface 7a of the recess 7 on the lower surface of the base, and the rotary plate 8 is removed from the base 2 There is no possibility of leaving upwards. When the rotary plate 8 is lifted upward, the rotary plate 8 is lifted from the base 2 by the gap t between the upper inner surface 7a of the recess 7 of the base 2 and the nut 13, and this causes the small balls 5 to roll. There is no possibility of falling off the concave grooves 3 and 9. Further, as described above, since there is a slight gap t between the nut 13 and the concave inner surface 7a on the lower surface of the base, there is no problem when the rotating plate 8 is rotated with respect to the base 2. Even when the flowerpot placing device 1 is moved to another place, the base 2 and the rotating plate 8 can be integrated without lifting by lifting the handle-like protruding portion 8a on the upper edge of the rotating plate 8 with both hands. Can be lifted. The above is an example of the means for preventing the detachment of the rotating plate 8, but other detaching preventing means for the rotating plate 8 can be adopted without preventing the rotating operation of the rotating plate 8 with respect to the base 2. Of course.

(Example 2)
The first embodiment is a type in which the rotating plate 8 on which the flower pot 10 is placed is manually rotated. In the second and third embodiments, a motor is incorporated to automatically rotate the rotating plate 8. First, in the second embodiment, a gear 16 is formed on the outer peripheral side portion of the rotating plate 8, and a small gear 17 is meshed with the gear 16. The small gear 17 is rotationally driven by a motor 20 via a speed reducer 18, whereby the rotating plate 8 is rotated with respect to the base 2. Except that the gear 16 is formed on the outer periphery of the rotating plate 8, the base 2, the rotating plate 8, and a large number of rolling elements (small spheres 5) interposed between the upper surface of the base and the lower surface of the rotating plate, etc. The means for preventing the detachment of the rotating plate 8 with respect to the base 2 and the like are substantially the same as in the first embodiment, and duplicate descriptions of similar parts are omitted as much as possible.

  The motor 20 is powered by a power supply device attached to the flowerpot placing device 1 or an external power supply. The operation time, supply voltage, rotation speed, and the like are controlled by a controller 21 attached to the motor 20. For example, the operation time is controlled by the controller 21 so that the motor 20 does not operate during rainy weather or at night. The rotational speed of the motor 20 is controlled so as to operate at a low speed such that the rotating plate 8 rotates once per hour, for example, in cooperation with the speed reducer 18. In addition, you may make it set this rotation speed to an appropriate rotation speed according to the kind of potted plant mounted in the rotation board 8. FIG.

(Example 3)
FIG. 4 is a longitudinal sectional view of the rotary flower pot placing device 1 according to the third embodiment of the present invention. In the third embodiment, the rotary plate 8 is automatically rotated by driving the motor. Unlike the second embodiment, the output shaft of the motor 20 is connected to the shaft portion fixed to the rotary plate 8 via a speed reducer. Gears are connected and the rotating plate 8 is rotated through the shaft portion. In the third embodiment, the shaft portion is constituted by a bolt 22. A bolt insertion hole 23 is formed at the center of the rotary plate 8, and a bolt insertion hole 25 having a larger diameter than the bolt insertion hole 23 is formed in the base 2, and the bolt 22 is inserted into the base 2 from the rotary plate 8. In this state, a nut 26 is screwed onto the bolt 22, and the bolt 22 is fixed to the rotary plate 8 by tightening the rotary plate 8 with the bolt head 22 a and the nut 26.

  A driven bevel gear 27 is attached to the lower end of the bolt 22 as shown in the figure, and a driving bevel gear 28 meshing with the driven bevel gear 27 is connected to the output shaft of the motor 20 via a speed reducer 29. The motor 20 is powered by a power supply device attached to the plant placement device or an external power supply. The operation time, supply voltage, rotation speed, and the like are controlled by a controller 21 attached to the motor 20. For example, the operation time is controlled by the controller 21 so that the motor 20 does not operate during rainy weather or at night. The number of rotations of the motor 20 is controlled so as to operate at a low speed such that the rotating plate 8 rotates once in one hour in cooperation with the speed reducer 29. In addition, you may make it set this rotation speed to an appropriate rotation speed according to the kind of potted plant mounted in the rotation board 8. FIG. By automatically rotating the platform on which the flower pot 10 is placed as in the second and third embodiments, the entire shape of the plant and the leaves collapse in the direction of light, without bothering human hands. Can be prevented. The present invention is particularly effective when used for the uniform growth of ornamental potted plants.

Example 4
Example 4 of FIG. 5 is a modification of Example 1, and has a configuration in which a flower pot placing plate 30 having a diameter larger than that of the rotating plate 8 is mounted on the upper surface of the rotating plate 8. By providing the large mounting plate 30, for example, a horizontally long and large rectangular flower pot 31 can be stably mounted and rotated as shown in the figure. The configurations of the rotating plate 8, the base 2, and the rolling elements of small balls arranged between the rotating plate and the base are the same as those in the first embodiment shown in FIGS. Is omitted. In addition, it is also possible to install a large-diameter flowerpot placing plate on the upper surface of the rotating plate in the motor-driven type of Example 2 and Example 3. In Example 4, an appropriate placement plate is installed according to the type, size, and weight of the applied flowerpot by replacing the large-sized flowerpot placement plate with another one depending on the situation. Therefore, it is possible to obtain a rotary flower pot placing device with a wide application range.

  In each of the above-described embodiments, the guide concave grooves 3 and 9 of the rolling element are formed on both the upper surface of the base and the lower surface of the rotating plate. However, this guide concave groove is formed only on one of the upper surfaces of the base, for example. However, it is possible in some cases to omit such a concave groove on the lower surface of the rotating plate. The rotary plate 8 is prevented from moving upward relative to the base 2 (detachment prevention means), and the large lateral movement of the rotary plate 8 is caused by the base 2 in the embodiment of FIG. Large displacement in the lateral direction of the bolt 12 is restricted by the insertion hole 6 of the base 2 due to the small gap between the formed bolt insertion hole 6 and the bolt 12.

  Further, in the example of FIG. 4, the inner wall 14 of the base 2 is formed so as to face the driven bevel gear 27 on the rotating plate side with a small gap, and thereby the lateral movement of the rotating plate 8 is controlled. Can be regulated. In FIG. 4, the upward restriction of the rotary plate 8 is performed by a gap t between the inner upper wall of the base 2 and the driven bevel gear 27. In any case, there is no hindrance to the rotation of the rotating plate 8 with respect to the base 2.

  According to these rotary flower pot placing devices, the rotary plate 8 can be slidably rotated in a state where the rotating plate 8 is held by the plurality of small balls 5 on the base 2 by the bearing structure composed of grooves and small balls. Not only flower pots but also large flower pots and multiple flower pots can be placed in a stable state. Therefore, the plants in the flower pot placed on the rotary flower pot placing device can grow evenly without growing biased toward the direction of the light source, and can maintain an aesthetic feeling suitable for viewing and photographing.
