Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a flower pot support stand that includes a support to which a pot holder is attached, and a synthetic resin pedestal on which the support is erected.

(Prior Art) In a conventional flower pot support stand, for example, as shown in FIG. 9, a support 28 is provided upright on a synthetic resin pedestal 26 via a holding cylinder 27. A plurality of resin pipes 29 with protruding pot holders are fitted onto the pedestal 26 so as to be stacked, and the pedestal 26
There is a device in which a resin pipe 29 and a resin pipe 29 are held between caps 30 and 31 screwed to both the upper and lower ends of the support column 28 (for example, Utility Model Application No. 56-108460).

(Problem to be solved by the invention) However, in this type of conventional support stand, the pedestal 26 is made only of synthetic resin, so when a flower pot is placed on the pot holder of each resin pipe 29, the center of gravity inevitably shifts. It had the disadvantage of being tall and easily falling over. In addition, when fixing the column 28 to the pedestal 26 side, after inserting a plurality of resin pipes 29 into the column 28, screw the caps 30 and 31 to both ends of the column 28, and attach the caps 30 and 31 to the pedestal. 26 and a plurality of resin pipes 29 had to be held between them, and the work of fixing the support column 28 was extremely troublesome.

In view of the above-mentioned problems, the present invention has been developed so that it can be installed stably so that it will not easily fall over, and the support can be easily fixed to the pedestal side.

(Means for Solving the Problems) The technical means of the present invention to solve this technical problem is to provide a support 1 to which a pot holder 3 is attached, and to hold the lower end of the support 1 in the vertical direction. In a flowerpot support stand comprising a synthetic resin base 9 having a holding cylinder part 10 and a skirt part 11 extending radially outward from the holding cylinder part 10 so as to protrude below the lower end of the cylinder part 10. , the skirt portion 1
An engagement groove 14 is formed on the inner surface of the lower end portion of the pedestal 9 and is recessed outward in the radial direction over substantially the entire circumference.
When the engagement groove 14 is in an expanded state immediately after molding,
A disc-shaped steel plate 17 is fitted so that the outer peripheral edge thereof is engaged over substantially the entire circumference, and a bolt shaft 22 projects from the lower end of the column 1 so as to pass through the center of the steel plate 17. A nut 24 is provided which is screwed onto a bolt shaft 22 so as to tighten and fix the support column 1 to the steel plate 17.

(Function) Since the lowest part of the flowerpot support base is made of a heavy steel plate 17, the center of gravity is lowered, and there is no fear that the flowerpot will fall easily when placed on the pot holder 3.
Moreover, after inserting the support column 1 into the holding cylinder part 10,
By threading and tightening the nut 24 onto the bolt shaft 22, the support 1 can be easily fixed to the pedestal 9.

(Embodiment) The present invention will be explained below according to the illustrated embodiment. In FIGS. 1 to 3, reference numeral 1 denotes a support made of a metal pipe, and the support 1 has a cylinder as shown in FIG. A pot holder 3 is attached via the body 2 so as to be rotatable and slidable up and down, and by fitting a fixing pin 5 into the keyway 4 of the cylindrical body 2, a plurality of pot holders 3 can be attached to the support 1. It is configured so that it can be detachably fixed in any rotational and sliding position. Also, pillar 1
A cap 6 is removably fitted inside the upper end of the cap.

Reference numeral 9 denotes a synthetic resin pedestal on which the support column 1 is erected, and includes a holding cylinder part 10 in the vertical direction, and a radially outward part extending from the upper end of the holding cylinder part 10 to the lower end of the cylinder part 10. It has a widened skirt part 11 integrally. As shown in FIG. 5, the holding cylinder part 10 internally holds the lower end of the support column 1 via a plurality of protruding strips 12 that project inward from the holding cylinder part 10. 13
5 are ribs provided on the pedestal 9, and a plurality of ribs are provided radially so as to connect the holding cylinder part 10 and the skirt part 11, as shown in FIG. Reference numeral 14 denotes an engagement groove provided in the skirt portion 11, which is formed in the inner surface of the lower end portion of the skirt portion 11 so as to be recessed radially outward in a V-shape over the entire circumference, as shown in FIG.

17 is a disc-shaped steel plate provided on the pedestal 9;
As shown in the drawings and FIG. 8, a mounting hole 18 is provided in the center, and a rib 19 bent downward in an arc shape is formed in an annular shape on the outer periphery. This steel plate 17 is fitted onto the lower end of the skirt portion 11 so that its outer peripheral edge engages with the engagement groove 14 over the entire circumference when the base 9 is in an expanded state immediately after resin molding.

In other words, synthetic resin molded products, such as polypropylene with a thickness of around 2 mm, generally shrink by about 18/1000, so they are formed using a mold that is 1.018 times larger than the product size, and immediately after molding, Assuming that the contraction is 50% complete, (1
The product will come out of the molding machine in a state that is +(18/1000) x (1-0.5)) times larger than the product size.
It is said that contraction is complete in about 24 hours. Therefore, by utilizing this property, for example, when the opening diameter B at the lower end of the pedestal 9 is 374 mm immediately after molding, a steel plate 17 with a diameter D of 373 mm is inserted through the lower end opening of the pedestal 9, and the pedestal 9 is held upside down for a while. cool,
If you store it in a box once the opening diameter B is 373mm or less, the opening diameter B will be 371mm approximately 24 hours later.
Thus, the outer peripheral edge of the steel plate 17 having a diameter D of 373 mm is engaged with the engagement groove 14 so that it is securely and irremovably fitted into the lower end of the skirt portion 11.

Reference numeral 22 denotes a bolt shaft provided on the column 1, which projects downward through a synthetic resin inner fitting member 23 that is fitted and fixed to the lower end of the column 1. It penetrates vertically through. A wing nut 24 is screwed onto the bolt shaft 22, and the support column 1 is tightened and fixed to the steel plate 17 by the nut 24. Note that 25 is a washer.

(Effect of the invention) According to the invention, the pedestal 9 has a skirt portion 11.
Since a disc-shaped steel plate 17 is fitted into the engagement groove 14 at the lower end so that the outer periphery thereof is engaged over the entire circumference, the weight of the steel plate 17 lowers the center of gravity of the flower pot support. Therefore, even if the flower pot is placed on the pot holder 3, the flower pot support can be stably installed without fear of falling. Further, a bolt shaft 22 is provided at the lower end of the column 1 so as to protrude through the center of the steel plate 17, and a nut 24 is provided which is screwed onto the bolt shaft 22 so as to tighten and fix the column 1 to the steel plate 17. Therefore, in order to fix the support column 1 to the pedestal 9 side, after inserting the lower end of the support column 1 into the holding cylinder part 10,
By screwing the nut 24 onto the bolt shaft 22 and tightening it, the column 1 can be fixed very easily. Moreover,
The steel plate 17 is fitted into the engagement groove 14 so that its outer periphery is engaged over the entire circumference when the pedestal 9 is in an expanded state immediately after being formed. This can be done reliably and easily without fear of it coming off or rattling, and the structure of the attachment part between the steel plate 17 and the pedestal 9 is also very simple, making it easy to manufacture and providing at low cost. Its practical effects are significant.
