Description

[Technical Field]

[0001] The present invention relates to a stand for supporting a pole for a flag or the like. [Background technology]

[0002] Traditionally, stands have been used to support flags that serve as advertisements or landmarks to attract customers at stores or event venues. In particular, various stands have been proposed that are provided with a storage space for storing water to make the stand heavier so that the flags and stands do not fall over due to the influence of wind or the like.

[0003] For example, Patent Document 1 describes a support device that has a hollow body that can be stacked, a weight body with an inlet / outlet for filling material, a groove-like slit section of appropriate width that is cut from the outer periphery, and a pole-standing section at an appropriate position on the top surface.

[0004] Furthermore, for example, Patent Document 2 describes a pole support base that includes a hollow body having a water storage section and a water supply and drainage port, a base having an attachment recess with an engagement notch, and a cylindrical body whose interior is formed as an insertion tube and has side protrusions on the outer periphery.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2020-204192 [Patent Document 2] Japanese Patent Application Publication No. 08-123347 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the water stands described in Patent Documents 1 and 2, when a hose or faucet is brought close to the opening and water is poured in, the opening is blocked by the hose or faucet, making it difficult to visually see the storage space from the opening and therefore difficult to ascertain how much water is stored in the storage space. In particular, if water continues to be poured into the storage space even though it has reached its maximum capacity, the water in the storage space cannot be drained, which could cause the storage space to burst and damage the stand. Furthermore, since the air trapped in the storage space cannot be released, there is a risk that the storage space may burst and damage the stand.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a stand that improves handling performance during use while preventing the storage space from bursting when water is poured into the storage space. [Means for solving the problem]

[0008] The present invention, which solves the above problem, is a stand for supporting a pole, comprising: a support part for supporting the pole; a storage space for storing water; an opening leading to the storage space; and a filter covering part of the opening, wherein the filter divides the opening into a plurality of openings.

[0009] According to the present invention, a filter covering part of the opening divides the opening into multiple openings, so that when water is poured into one of the multiple openings, the water and air in the storage space are discharged from the remaining openings, thereby preventing the storage space from bursting.

[0010] In a preferred embodiment of the present invention, the plurality of openings include a water inlet that allows water to be supplied to and drained from the storage space, and a drain outlet for draining water stored in the storage space, and the water inlet is configured to allow a hose to be attached that supplies water to the storage space. With this configuration, water can be supplied to the storage space with the hose inserted into the water inlet, preventing water from being sprayed around the stand.

[0011] In a preferred embodiment of the present invention, the drain ports are formed so that the total area of ​​all the drain ports is larger than the area of ​​the water passage ports in a plan view. With this configuration, when the storage space is filled to its maximum capacity with water and a hose is inserted into the water inlet to supply water to the storage space, the amount of water drained from the storage space will be the same as the amount of water supplied to the storage space or the amount of water discharged will be greater than the amount of water supplied, preventing the storage space from bursting.

[0012] In a preferred embodiment of the present invention, a lid is provided that covers the opening from above the filter. This configuration prevents the water stored in the storage space from unintentionally leaking out or evaporating. In addition, it is possible to open and close the water inlet and the drain outlet simultaneously with a single operation.

[0013] In a preferred embodiment of the present invention, corresponding threads are formed on the inner periphery of the opening and the outer periphery of the filter, and the filter is detachably screwed onto the inner periphery of the opening. This configuration allows the filter to be removed and replaced if it becomes damaged or soiled. It also prevents the filter from coming off the opening when draining water from the storage space.

[0014] In a preferred embodiment of the present invention, the filter is provided with a lid that covers the opening from above, the lid having a threaded portion with a screw thread that corresponds to the inner surface of the opening, and the filter and the threaded portion are configured to have the same diameter when viewed in plan. With this configuration, the filter and the lid can use the same screw hole (opening), making it relatively easy to form an opening that can be opened and closed by the filter and the lid.

[0015] The present invention is a stand for supporting a pole, comprising: a support part for supporting the pole; a storage space for storing water; an opening leading to the storage space; a filter covering part of the opening; and a lid part covering the opening from above the filter, wherein the filter has a filter body that divides the opening into a plurality of openings; and a protruding part protruding from the filter body, the protruding part having a screw thread formed on its inner surface; and the lid part having a screw-threaded part with a screw thread formed on the inner surface of the protruding part, and the lid part is removably screwed onto the inner periphery of the protruding part.

[0016] With this configuration, the filter covering part of the opening divides the opening into multiple openings, so that when water is poured into some of the multiple openings, the air in the storage space is discharged from the remaining openings, preventing the storage space from bursting. Furthermore, since the opening is airtightly sealed by both the filter and the lid, the storage space is kept sealed, making it possible to further prevent the water stored in the storage space from evaporating.

[0017] Another aspect of the present invention is a filter as described above. [Effects of the Invention]

[0018] According to the present invention, it is possible to provide a stand that improves handling performance during use and prevents the storage space from bursting when water is poured into the storage space. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] First Embodiment A stand according to a first embodiment of the present invention will be described below with reference to FIGS. The embodiment shown below is an example of the present invention, and the present invention is not limited to the embodiment shown below. In these drawings, reference numeral 1 denotes a stand according to the first embodiment. The wavy lines indicate that the drawing range is omitted.

[0021] <Configuration> As shown in Figures 1 to 4, the stand 1 includes a support portion 11 that supports the pole, a storage space 12 for storing water, an opening 13 that leads to the storage space 12, a filter 14 that covers part of the opening 13, and a lid portion 15 that covers the opening 13 from above the filter 14. Although plastic is preferably used for the stand 1, there are no particular limitations on the material as long as it has enough rigidity to maintain its shape when not subjected to external force.

[0022] The support portion 11 has a support hole 111 penetrating the bottom surface (not shown) of the stand 1 that comes into contact with the ground, and is provided at the center of gravity of the stand 1 in a plan view. As a result, the pole part FP (see FIG. 7) is inserted into the center of gravity of the stand 1, making it possible to stably support the banner F (see FIG. 7). Furthermore, because the support holes 111 are through-holes, the center of gravity of the flag F is positioned lower, which results in stable support of the flag F. In addition, water is prevented from accumulating in the support parts 11 after the stand 1 is exposed to rain or snow.

[0023] A screw thread P that is threadedly engaged with a fixing member (not shown) that fixes the pole portion FP (see FIG. 7) is provided on the inner peripheral surface of the support hole 111. This makes it possible to fix the fixing member (not shown) inserted into the support hole 111. The diameter of the support hole 111 is formed so that it increases monotonically upward. As a result, the diameter of the upper part of the support hole 111 is larger than the diameter of the pole part FP (see FIG. 7), making it easy to attach and detach the pole part FP to and from the support hole 111. This also makes it possible to fix a fixing member (not shown) inserted into the support hole 111.

[0024] As shown in FIG. 3( a ), the opening 13 communicates with the storage space 12 . This allows water to be poured into the storage space 12 through the opening 13, and also allows the water poured into or accumulated in the storage space 12 to be drained to the outside.

[0025] The top surface of the storage space 12 is formed in a curved shape except for the portion adjacent to the support portion 11. This prevents damage to the storage space 12 and the stand 1 due to an increase in pressure within the storage space 12.

[0026] The opening 13 is integrally formed and protrudes from the top surface of the storage space 12.

[0027] The opening 13 is airtightly sealed by a filter 14 and a lid 15, which will be described later. This improves the airtightness of the storage space 12, and makes it possible to further suppress evaporation of water stored in the storage space 12 even without providing a packing.

[0028] As shown in FIG. 2 or FIG. 4( a ), the filter 14 has a filter body 141 that divides the opening 13 into a plurality of openings, and a protruding portion 142 that protrudes from the filter body 141 .

[0029] The filter 14 is fixed to the inner peripheral surface of the opening 13 . This prevents the filter 14 from coming off from the opening 13 when the cover 15, which will be described later, is rotated.

[0030] The filter body 141 is provided with a water inlet 141a through which water can be supplied to and drained from the storage space 12, and a drain outlet 141b through which water stored in the storage space 12 can be drained. As a result, the filter 14 divides the opening 13 into a plurality of openings.

[0031] The diameter of the water passage port 141a is formed to be slightly larger than the size of a general water hose, and may be, for example, 1.8 cm to 2.2 cm. This allows a hose H (see FIG. 6) for supplying water to the storage space 12 to be attached to the water passage 141a.

[0032] A plurality of drain ports 141b are provided outside the water inlet port 141a in a plan view, and allow drainage and ventilation when a hose is attached. In particular, in order to improve the strength of the filter body 141, a rib may be provided to connect the outer periphery of the drain port 141b and the member that separates the water inlet port 141a.

[0033] The drain ports 141b are formed so that the total area of ​​all the drain ports 141b is larger than the area of ​​the water passage ports 141a in plan view. This makes it difficult for the internal pressure of storage space 12 to increase when water is supplied. For example, when water is supplied through water inlet 141a when the tank is full, an amount of water equal to the amount of water supplied is discharged from drain outlet 141b, preventing damage to stand 1. Furthermore, if the internal pressure in storage space 12 increases due to supplying water at high water pressure or if a dent is created in storage space 12 due to an external force during water supply, the amount of water drained from drain outlet 141b will be greater than the amount of water supplied from water inlet 141a, preventing damage to storage space 12 and stand 1.

[0034] In addition, the drain outlets 141b are formed so that the total area of ​​the drain outlets 141b is larger than the area of ​​the water passage ports 141a in any area where the filter body 141 is divided by any straight line in a plan view. This makes it easier to tilt the stand 1 and drain the water in the storage space 12.

[0035] The protruding portion 142 protrudes from the top surface of the filter body 141 along the edge thereof. The inner peripheral surface of the protruding portion 142 is formed with a screw thread 14R that corresponds to a screw-engaging portion 152 of the lid portion 15, which will be described later. 3(b), the threaded portion 152 can be detachably threadedly engaged with the filter 14. In addition, the thread 14R is formed from the upper end surface of the filter body 141 to the upper end surface of the protruding portion 142, thereby further improving airtightness.

[0036] As shown in Figure 3(b) or Figure 4(b), the lid portion 15 has a gripping portion 151 that is gripped by the user and a screwing portion 152 that is screwed onto the inner surface of the protruding portion 142 of the filter 14.

[0037] The grip portion 151 is formed in a rectangular shape with rounded corners when viewed from the front. This makes it possible to prevent a user from getting injured when gripping the grip portion 151.

[0038] The threaded portion 152 is formed with a thread 15R that corresponds to the thread 14R provided on the filter 14. This makes it possible to simultaneously open and close the water inlet 141a and the drain outlet 141b with a single operation.

[0039] <How to use> Hereinafter, a method of using the stand 1 will be described with reference to FIGS.

[0040] When attaching the flag F to the stand 1, as shown in FIG. 5, the user first grasps the grip portion 151 and rotates the lid portion 15 to remove the lid portion 15 from the filter 14.

[0041] Next, as shown in FIG. 6, the user attaches a hose H connected to a water supply source (not shown) to the water port 141a.

[0042] Next, the user runs water through the hose H, and the water accumulates in the storage space 12, which is connected to the water outlet 141a. At this time, since no water flows into the drain outlet 141b, the air in the storage space 12 is released to the outside.

[0043] Next, after the user confirms that the desired amount of water has been stored in the storage space 12 through the drain outlet 141b, he or she stops the water supply from the water supply source (not shown) and removes the hose H from the water inlet 141a. At this time, even if the user continues to supply water without noticing that the maximum capacity of water in the storage space 12 has been stored in the storage space 12, the water in the storage space 12 is discharged to the outside from the drain outlet 141b.

[0044] Next, the user attaches the cover portion 15 to the filter 14, and then inserts the pole portion FP of the flag F into the support portion 11 as shown in FIG. In this way, the flag F can be supported.

[0045] When draining the water stored in the storage space 12, the user first removes the pole part FP inserted into the support part 11. Next, as shown in FIG. 5, the user grasps the grip part 151 and rotates the lid part 15 to remove the lid part 15 from the opening 13.

[0046] Next, the user holds the stand 1 and tilts it so that water drains from the opening 13. At this time, water may be drained not only through the water inlet 141a but also through the drain outlet 141b, but since there are multiple drain outlets 141b, air flows into the storage space 12 from the drain outlets 141b that are not draining. This makes it possible to easily drain the water stored in the storage space 12.

[0047] In this way, the water stored in the storage space 12 can be drained.

[0048] In the above-described method of use, water is stored in the storage space 12, but it is not limited to water and may be sand, for example.

[0049] <Effects> According to this embodiment, the filter 14 covering part of the opening 13 divides the opening 13 into multiple openings, so that when water is poured into some of the multiple openings, the water and air in the storage space 12 are discharged from the remaining openings, thereby preventing the storage space 12 and the stand 1 from bursting.

[0050] In addition, the filter 14 has a water inlet 141a that can supply water to and drain water from the storage space 12, and a drain outlet 141b for draining water stored in the storage space 12, and the water inlet 141a is configured to be able to attach a hose H that sends water to the storage space 12, so that water can be supplied to the storage space 12 with the hose H inserted into the water inlet 141a, preventing water from being sprayed around the stand 1.

[0051] The drain outlets 141b are formed so that the total area of ​​all the drain outlets 141b is larger than the area of ​​the water inlet 141a in a plan view. Therefore, when the maximum volume of water is stored in the storage space 12 and the hose H is inserted into the water inlet 141a to supply water to the storage space 12, the amount of water drained from the storage space 12 and the amount of water supplied to the storage space 12 will be the same or greater than the amount of water drained, preventing the storage space 12 from bursting.

[0052] Furthermore, the provision of a lid 15 that covers the opening 13 from above the filter body 141 prevents the water stored in the storage space 12 from unintentionally leaking out or evaporating. In addition, it is possible to simultaneously open and close the water inlet 141a and the drain outlet 141b with a single operation.

[0053] In addition, the filter 14 has a filter body 141 that divides the opening 13 into multiple openings, and a protruding portion 142 that protrudes from the filter body 141, and the inner surface of the protruding portion 142 has a screw thread 14R formed thereon, and the lid portion 15 has a screw-engaging portion 152 that has a screw thread 15R formed thereon that corresponds to the inner surface of the protruding portion 142, and is detachably screwed onto the inner periphery of the protruding portion 142.Since the opening 13 is airtight by both the filter 14 and the lid portion 15, the airtightness of the storage space 12 is improved, and it is possible to further suppress the evaporation of water stored in the storage space 12.

[0054] Second Embodiment The configuration of a stand 2 according to the second embodiment of the present invention will be described below with reference to FIGS. Note that the configurations described in the configuration of the first embodiment but not shown below are the same as those of the first embodiment. Furthermore, the embodiment shown below is an example of the present invention, and the present invention is not limited to the following embodiment. In these figures, the reference numeral 2 denotes a stand according to a second embodiment.

[0055] As shown in Figures 8 to 11, the stand 2 includes a support part 21 that supports the pole, a storage space 22 for storing water, an opening 23 that leads to the storage space 22, a filter 24 that covers part of the opening 23, and a lid part 25 that covers the opening 23 from above the filter 24.

[0056] The stand 2 has the shape of a square truncated pyramid with rounded corners.

[0057] As shown in FIG. 9 or FIG. 10(a), an opening 23 is provided on the top surface of the stand 2 and communicates with the storage space 22.

[0058] Further, on the inner circumferential surface of the opening 23, near the lower end, a screw thread 23R is formed that corresponds to both the outer circumferential surface of the filter 24 described later and the screw portion 252 of the lid portion 25. This allows the filter 24 and the threaded portion 252 to be detachably threadedly engaged with the opening 23 .

[0059] The inner peripheral surface of the opening 23 on which the thread 23R is provided is formed to have the same diameter in a plan view.

[0060] The opening 23 is formed so that the diameter thereof increases monotonically toward the external space. This makes the diameter of opening 23 close to the external space larger than the diameters of filter 24 and lid 25, making it easy to attach filter 24 and lid 25 to and detach from thread 23R.

[0061] As shown in Figure 9 or Figure 11(a), the filter 24 is provided with a water inlet 24a that allows water to be supplied to and drained from the storage space 22, and a drain outlet 24b for draining the water stored in the storage space 22.

[0062] The lower end of the water inlet 24a is located lower than the lower end of the drain outlet 24b. This makes it easier for the attached hose to point downward. Other features of the water passage port 24a and the drain port 24b are configured in the same manner as the water passage port 141a and the drain port 141b in the first embodiment.

[0063] The filter 24 has a screw thread 24R on its outer circumferential surface, and the screw thread 24R is formed so as to be able to be screwed onto the screw thread 23R provided on the opening 23. This allows the filter 24 to be detachably screwed into the opening 23 .

[0064] As shown in Figure 10(b) or Figure 11(b), the lid portion 25 has a gripping portion 251 that is gripped by the user, a threaded portion 252 that is threadedly engaged with the filter 24, and a gasket 253 that abuts against the top surface of the stand 1.

[0065] The threaded portion 252 is formed with a thread 25R that corresponds to the inner peripheral surface of the opening 23 and corresponds to the thread 24R provided on the filter 24. On the other hand, the thread 24R and the thread 25R may be provided in a reverse thread relationship to make them less likely to come off unintentionally.

[0066] The packing 253 is formed to have a diameter larger than the diameter of the opening 23 in a plan view, and is in close contact with the top surface of the stand 2. This improves the airtightness of the storage space 22, and inhibits the water stored in the storage space 22 from evaporating.

[0067] With the above configuration, corresponding screw threads 23R, 24R are formed on the inner circumferential surface of opening 23 and the outer circumferential surface of filter 24, respectively, and filter 24 is detachably screwed onto the inner circumferential surface of opening 23. Therefore, if filter 24 is damaged or soiled, it can be removed and replaced. In addition, filter 24 is prevented from coming off opening 23 when draining water from storage space 22.

[0068] Furthermore, the lid portion 25 has a threaded portion 252 on which a thread 25R corresponding to the inner peripheral surface of the opening 23 is formed, and the filter 24 and the threaded portion 252 are configured to have the same diameter in a planar view, so that the opening 23 and thread 23R that are common to the filter 24 and the lid portion 25 can be utilized, making it possible to relatively easily form an opening 23 that can be opened and closed using the filter 24 and the lid portion 25.

[0069] <Example of change> The shapes and dimensions of the components shown in the above two embodiments are merely examples and can be modified in various ways based on design requirements and the like.

[0070] For example, the support portion 11 may have a fixing member that helps support the pole portion FP, thereby making it possible to support the pole portion FP more stably.

[0071] For example, the diameter of protrusion 142 may be approximately the same as the diameter of support hole 111. This allows threaded portion 152 to be inserted into support hole 111 when lid portion 15 is removed from opening 13, thereby preventing lid portion 15 from being lost. Similarly, the diameter of the opening 23 may be approximately the same as the diameter of the support hole 211 .

[0072] For example, a plurality of openings 13 may be provided, and filters 14 and lids 15 may be provided correspondingly. This makes it easy to drain the water stored in the storage space 12 to the outside by opening the plurality of openings 13. Similarly, a plurality of openings 23 may be provided, and filters 24 and lids 25 may be provided correspondingly.

[0073] For example, the periphery of the opening 23 may be configured to be raised except for a portion, or the opening 23 may be provided so as to be inclined outward relative to the horizontal plane. This makes it possible to control the flow of water overflowing from the opening 23 to some extent. Furthermore, for example, grooves for guiding water may be provided on the surface of the stand 1.

[0074] For example, the stands 1 and 2 may be provided with grips (not shown) on their sides. This makes it easy to carry the stands 1 and 2.

[0075] In addition to being used as stands for flags, stands 1 and 2 can also be suitably used as stands for chain poles or parasols. [Explanation of symbols]
