JP 2004-205642 A

By the way, there is a stand in which poles such as a streamer and a flag are attached to a column part standing on a pedestal part according to time. Even in such a stand, there is a demand for applying the above-described conventional stand to prevent the support portion from rattling.
In that case, since a carp streamer, a flag, etc. fly in the wind, a vibration is transmitted to the pedestal part through the support column part, and a part of the pedestal part may be lifted from the installation surface by the vibration.
From this point, it is conceivable to increase the installation pressure on the installation surface of the pedestal part by placing a heavy object (for example, a concrete block) serving as a weight on the pedestal part.

However, if a heavy object is simply placed on the pedestal part, the heavy object may be displaced due to the vibration transmitted to the pedestal part via the support part, and the heavy object may be displaced and detached from the pedestal part. Then, the installation pressure with respect to the installation surface of a base part cannot be raised reliably.
In addition, if the support is held only at the lower end with respect to the pedestal, the vibration transmitted to the pedestal via the support will act intensively only at the lower end of the support, thereby supporting the support efficiently. The stability of the support column is impaired.

  The present invention has been made in view of the above points, and the object of the present invention is to install the pedestal portion by reliably preventing the detachment of heavy objects from the pedestal portion while improving the stability of the support column. It is providing the stand which can raise the installation pressure with respect to a surface.

  In order to achieve the above object, the present invention is premised on a stand including a pedestal portion installed on a flat installation surface and a column portion erected on the pedestal portion. The pedestal portion has a substantially rectangular shape in plan view, and stands up from the base on which a heavy object serving as a weight is placed, and the periphery of the pedestal portion surrounding the base, and the base The lower end of the support column is provided at an approximately central position of an edge that regulates dropping of heavy objects from the edge and one of the edges facing each other and extending in parallel with the one facing edge. A base end is swingably supported via a column support portion that is swingably supported, and an axis that extends in parallel with the other facing edge on both ends of the other facing edge of the edge. And a supporting member that extends while avoiding interference and has each tip fixed to a middle position of the support column through a fixture.

Due to this specific matter, a heavy object (for example, a concrete block) that becomes a weight placed on the base of the pedestal is restricted from falling off the base by an edge that rises upward from the periphery of the pedestal. Yes. For this reason, even if a swing is transmitted to the pedestal part via the support column when a carp streamer or a flag flutters in the wind, the heavy object is not displaced and detached from the base of the pedestal part. Thereby, it becomes possible to raise the installation pressure with respect to the installation surface of a base part smoothly with a heavy article.
In addition, the middle position of the column portion, the lower end of which is supported by the column support portion at the substantially central position of one of the opposed sides of the pedestal portion, is supported at the base end at both ends of the other opposed side of the pedestal portion. Since it is being fixed by the fixture of the front-end | tip of each support member, the middle position of a support | pillar part is supported from the both ends of the other opposing side which faces the lower end of the support | pillar part. For this reason, the vibration transmitted to the pedestal part via the support part is distributed to the lower end of the support part and both ends of the opposite side facing the lower end, so that the support part can be efficiently supported and the stability of the support part. It becomes possible to improve the nature.

  In addition, a clamp tool having a flange that is open at one end in the circumferential direction so that the fixing tool can be clamped with a reduced diameter with respect to the outer peripheral surface in the middle of the support column, and a flange that faces each other at the open end; Inserted in a state in which the hole provided at the tip of each support member is aligned with the insertion hole provided in each flange, and tightened so that the flanges are close to each other, and the outer circumference of the intermediate position of the column portion It is preferable that a screw member that clamps the clamp tool by reducing the diameter on the surface is provided.

  In this case, the clamp tool is reduced in diameter by tightening the tips of the support members so that the flanges are brought close to each other by a screw member inserted through the hole at the tip and the insertion hole of each flange of the clamp tool. Thus, it is smoothly fixed to the outer peripheral surface at the middle position of the support column. For this reason, if it is on the swing locus of the tip of each support member whose base end swings around the axis at both ends of the other opposite side of the pedestal part, the column part around the axis of the column support part of the pedestal part The tip of each support member is fixed anywhere in the middle position. Thereby, the support | pillar part is supported by each support member with a favorite swing angle, and the freedom degree of the swing angle of a support | pillar part can be expanded.

  Furthermore, each said supporting member may be bent so that it may extend to the middle position, maintaining the space | interval of the base ends, and each front-end | tip may go to the middle position of the said support | pillar part from this middle position.

  In this case, since each support member extends while maintaining the interval between the base ends to the middle position, interference with the weight placed on the base of the pedestal can be smoothly avoided, such as a concrete block. Even bulky objects can be easily placed on the base of the pedestal.

  In short, in short, an edge that rises upward from the peripheral edge of the pedestal portion and restricts dropping of heavy objects from the base is provided, and the column support portion is located at substantially the center position of one opposing side of the pedestal portion facing each other. By fixing the mid-point position of the support column, the lower end of which is supported by the fixtures at the distal ends of the support members, the base ends of which are supported on both ends of the other opposite side of the pedestal, The installation pressure against the installation surface of the pedestal is ensured by preventing the detachment of heavy objects from the base of the pedestal due to the vibration transmitted to the pedestal through the support while supporting and improving the stability of the support. Can be increased smoothly by a heavy object.

  Further, as shown in FIG. 4, each of the support members 24 is formed in a pipe shape, and flat plate-like support pieces 241 and 242 are integrally provided at the base end and the distal end thereof, respectively. Each of the support pieces 241 and 242 is provided with a bolt insertion hole 243 (only one is shown in FIG. 5) as a hole. Further, bolt insertion holes (in the rear end portions of the left and right long edges 221 and 222 which are the left and right ends of the rear short edge 224 (the right side in FIG. 1) as the other opposing edge of the edges 22 are provided. (Not shown) is provided. The support piece 241 at the base end of each support member 24 is rotatable by the rivet 71 in a state where the bolt insertion hole 243 is matched with the bolt insertion holes at the rear end portions of the left and right long edges 221 and 222. It is supported by. In this case, the axis of the rivet 71 functions as an axis extending in parallel with the rear short edge 224, and the base end of each supporting member 24 is swung in the front-rear direction with respect to the rear end portions of the left and right long edges 221 and 222. Supports freely.

  On the other hand, as shown in FIGS. 5 and 6, the support piece 242 at the tip of each support member 24 is fixed to the middle position of the support column 3, that is, the upper end position of the lower hollow pipe 31 via the fixture 4. Has been. The fixing device 4 has flanges 41, 41 that open at one end in the circumferential direction so that they can be clamped by reducing the diameter with respect to the outer peripheral surface at the upper end position of the lower hollow pipe 31, and face each other at the open end. Are inserted into the clamp tool 42, the insertion hole 411 (only one is shown in FIG. 5) provided in each flange 41, and the bolt insertion hole 243 (only one is shown in FIG. 5) at the tip of each support member 24. The butterfly bolt 43 and the butterfly nut as screw members are clamped by tightening the flanges 41 and 41 close to each other to reduce the diameter of the clamp tool 42 to the outer peripheral surface at the upper end position of the lower hollow pipe 31. 44. In this case, the support column 3 (lower and upper hollow pipes 31 and 32) is supported by the support column support unit 23 and the support members 24 in a state slightly inclined backward from the vertical line.

  Further, as shown in FIG. 1, the pipe portion of each support member 24 has a base end so as to avoid interference with the two water injection tanks W1 and W1 placed on the base 21 of the base portion 2. Extending to a midway position (for example, a position about two-fifths from the base end) while keeping the distance between each other, it is bent inward so as to go to the upper end position of the hollow pipe 31 below the midway position. .

Next, a procedure for assembling the stand 1 will be described.
First, the pedestal portion 2 is set on the flat ground surface of the garden, and the distal end (support piece 242) is erected upward with each support member 24 as a fulcrum of the base end (support piece 241). At this time, the fixture 4 is attached to the tip of each support member 24 in a state in which the wing bolt 43 and the wing nut 44 are loosened and the clamp tool 42 is expanded in diameter.

  Next, the lower end of the lower hollow pipe 31 is supported on the support column support 23. That is, the through holes 33 and the bolts in the state where the through holes 33 at the lower end of the lower hollow pipe 31 are matched with the bolt insertion holes 252 of the facing pieces 251 and 251 of the convex portion 25 of the front short edge 223. The lower end of the lower hollow pipe 31 is supported on the support column support 23 by a butterfly bolt 35 and a butterfly nut 36 inserted into the insertion hole 252. At this time, each through hole 33 at the lower end of the lower hollow pipe 31 has a shorter length from the end portion than each through hole 33 at the upper end, so that an attachment error does not occur.

  Thereafter, the lower hollow pipe 31 is inserted into the clamp tool 42 of the fixture 4 from the upper end, and then the lower end of the upper hollow pipe 32 is inserted into the lower hollow pipe 31 from the upper end thereof, and the through holes 33 are connected to each other. It is attached by a wing bolt 35 and a wing nut 36 which are inserted into the respective through holes 33 in a state of being matched with each other.

  Then, the lower end of the proximal pipe member 52 of the telescopic pole 5 is inserted into the upper end of the upper hollow pipe 32, and the through hole 33 at the upper end of the upper hollow pipe 32 and the lower end of the proximal pipe member 52 of the telescopic pole 5 are penetrated. In a state where the holes 56 are aligned with each other, the heat-on bolts 59 are inserted and fixed with wing nuts. At this time, the telescopic pole 5 is fixed by the lock member 57 by extending the pipe members 53 to 55 respectively. Further, by fixing the fixture 4 at the tip of each support member 24, that is, by tightening the butterfly bolt 43 and the wing nut 44 to reduce the diameter of the clamp tool 42, the tip of each support member 24 is attached to the upper end of the lower hollow pipe 31. Is fixed.

  Thereafter, two empty water injection tanks W1 and W1 are placed on the base 21 of the base 2 and water is injected into each water injection tank W1 using a hose or the like.

  Therefore, in the above embodiment, the two water injection tanks W1 and W1 placed on the base 21 of the pedestal part 2 are dropped from the base 21 by the edge 22 rising upward from the peripheral edge of the pedestal part 2. Is regulated. Therefore, even if a swing is transmitted to the pedestal portion 2 via the telescopic pole 5 and the support column portion 3 when the streamer, the flag, etc. fly in the wind, each water injection tank W1 is not displaced and does not separate from the base 21. . Thereby, the installation pressure with respect to the ground surface of the base part 2 can be raised smoothly by each water injection tank W1.

  Further, the upper end position of the lower hollow pipe 31 supported at the lower end by the support column support part 23 at the approximate center position of the front short edge 223 of the pedestal part 2 is the rear end part of the left and right long edges 221 and 222, respectively. Since the base end is fixed by the fixture 4 at the tip of each supporting member 24 supported, the left and right ends of the rear short edge 224 where the upper end position of the lower hollow pipe 31 faces the lower end of the hollow pipe 31 Supported from the side. For this reason, the vibration transmitted to the pedestal portion 2 via the support column 3 is dispersed between the lower end of the support column 3 and the left and right ends of the rear short edge 224 facing the lower end, thereby supporting the support column 3 efficiently. Therefore, the stability of the column part 3 can be improved.

  Further, since each support member 24 extends to a midway position while maintaining the distance between the base ends, interference with each water injection tank W1 placed on the base 21 of the pedestal portion 2 can be smoothly avoided and bulky. Even a heavy object can be easily placed on the base 21 of the base 2.

  In addition, this invention is not limited to the said embodiment, The other various modifications are included. For example, in the above-described embodiment, the support column 3 is supported by the support column support unit 23 and each support member 24 in a state slightly inclined backward from the vertical line. However, as shown in FIG. 23 and each support member 24 may be supported in a standing state on the vertical line. In other words, if the base ends of the rear ends of the left and right long edges 221 and 222 are on the swing trajectory of the tip of each support member 24 that swings about the axis of the rivet 71, the column support portion 23 of the base portion 2. The lower hollow pipe 31 is swung around the axis of the butterfly bolt 35, and the tip of each support member 24 is fixed by the fixture 4 anywhere in the middle. Thereby, the support column 3 is supported by each support member 24 at a preferred swing angle, and the degree of freedom of the swing angle of the support column 3 can be increased.

  Moreover, in the said embodiment, although two rectangular box-shaped water injection tanks W1, W1 were applied as the heavy article W, as shown in FIG. 8, five PET bottles W2, W2,. Alternatively, as shown in FIG. 9, two concrete blocks W <b> 3 and W <b> 3 may be placed on the base 21.

  Moreover, in the said embodiment, although the long edges 221 and 222 of the base part 2 were set to 480 mm and the short edges 223 and 224 were each set to 345 mm, the dimension of the long edge and short edge of a base part is limited to this. Needless to say, in order to increase the weight of a heavy article, it may be set to a dimension larger than this.

  Further, in the above embodiment, the support column support portion 23 is provided at substantially the center position of the front short edge 223, and the base ends of the support members 24 are supported by the rear end portions of the left and right long edges 221, 222. The support portion may be provided at substantially the center position of one long edge facing each other, and the base end of each support member may be supported at the corresponding position of the short edge corresponding to the left and right end portions of the other long edge.

  Moreover, in the said embodiment, although the case where the base part 2 of the stand 1 was installed on the ground was described, if the base part of a stand is a flat installation surface regardless of the outdoors or indoors, it is installed anywhere. It goes without saying.

  Moreover, in the said embodiment, the expansion pole which consists of three pipe materials 53-55 accommodated in the upper end of the upper hollow pipe 32 at the upper end with respect to the base end pipe material 52 and this base end pipe material 52 so that expansion-contraction is possible. 5, the telescopic pole is composed of a base pipe material attached to the upper end of the upper hollow pipe 32 and two or four or more pipe materials accommodated so as to be stretchable with respect to the base pipe material 52. It goes without saying that it may be done.

  Moreover, in the said embodiment, although the pipe part of each supporting member 24 was extended to the middle position of about 2/5 from the base end, maintaining the space | interval of base ends, the pipe part of each supporting member is a base. You may extend from the base end to the middle position of 2/5 or more, maintaining the space | interval of base ends so that interference with the bulky heavy article mounted on the base of the part may be avoided. In this case, the pipe portion of each support member is bent inward so as to go to the upper end position of the hollow pipe 31 below the midway position.

  Furthermore, in the said embodiment, although the telescopic pole 5 to which the windsock and the streamer were attached was supported by the support | pillar part 3, pipes, such as an extendable pole to which the scissors were attached, may be supported by the support | pillar part.
