Description

[Technical field]

[0001] This invention relates to a pole stand for stretching barricade tape or anti-intrusion bars to prevent people or vehicles from entering. [Background technology]

[0002] Conventionally, in order to prevent people and vehicles from entering around no-entry areas and at the entrances to no-passage passages, it has been common to suspend bridge members such as cone bars, barricade tapes, and chains over guard cones (see Patent Documents 1 and 2). Among these, cones that are suspended using two types of bridge members have been proposed (see Patent Document 2).

[0003] For example, Patent Document 2 proposes a guard cone in which a pair of rod-shaped hooks are provided on a ring-shaped flat portion near the upper end of the cone, and the hoop portion of the cone bar is attached to the upper end of the cone and a chain is attached to the rod-shaped hooks. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2021-127656 A [Patent Document 2] Japanese Patent Application Laid-Open No. 10-074295 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the method of wrapping barricade tape around a guard cone disclosed in Patent Document 2, the barricade tape is wrapped around the entire circumference of the guard cone, which can make it difficult to use the barricade tape in combination with the cone bar.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a pole stand that can accommodate hanging cone bars while also securing space for attaching and hanging barricade tape. [Means for solving the problem]

[0007] The invention made to solve the above problem is a pole stand for hanging an anti-intrusion tape or cone bar. The pole stand for solving the above problem includes a support part, a ring-shaped handle part, and a connection part. The support part extends in a rod-like shape in the vertical direction. The handle part is located above the support part, and an opening faces the horizontal direction. The connection part connects the upper end of the support part and the lower end of the handle part. The support part has a column part and a cone part. The column part has a constant diameter in the vertical direction. The cone part is located above the column part, and a ring-shaped hoop provided on the cone bar is hung on the column part. The outer diameter of the column part in the horizontal direction is larger than the inner diameter of the hoop. The outer diameter of the cone part in the horizontal direction becomes smaller the higher it is. The outer diameter of the handle part in the horizontal direction is smaller than the inner diameter of the hoop. In this way, in addition to the support portion, a handle portion and a connection portion are provided, and further, the support portion is provided with a cone portion on which a cone bar can be hung. Therefore, the pole stand of the present invention can secure space for attaching and hanging barricade tape while also being able to hang a cone bar.

[0008] In the pole stand of the present invention, it is preferable that the horizontal length of the connecting portion is smaller than the outer diameter of the handle portion. Therefore, the amount of barricade tape required is smaller than that required when, for example, barricade tape is wrapped around the pole and then applied, making it easier to wrap and apply.

[0009] In the pole stand of the present invention, it is preferable that the horizontal length of the connecting portion is the same as the diameter of the top portion indicating the upper end of the cone portion. This makes it difficult for the hoop portion of the cone bar to get caught on the connecting portion.

[0010] In the pole stand of the present invention, the handle portion preferably has a longitudinal shape in the vertical direction, thereby making it possible to secure a space for wrapping and attaching barricade tape around the handle portion while passing it through an opening in the handle portion.

[0011] In the pole stand of the present invention, it is preferable that the handle portion includes a straight extending portion extending along the vertical direction, whereby the contact surface of the handle portion with the barricade tape can be configured to be flat, making it difficult for the barricade tape to peel off.

[0012] In the pole stand of the present invention, the support part preferably has a chain insertion hole which is a through hole penetrating horizontally at the upper end and has a cylindrical wall connecting both end openings of the through hole to isolate the inside of the through hole from the inside of the support part. The chain insertion hole preferably has a straight rod-shaped locking bar which extends vertically from the bottom surface of the chain insertion hole and has a free end at the middle part in the penetrating direction. The support part preferably has a pair of recesses which are horizontally opposed in recess direction. The chain insertion hole is preferably provided so as to connect the pair of recesses. The recesses preferably have a height including the total height of both end openings of the chain insertion hole, extend vertically and horizontally to the chain insertion hole, and both ends are open to the sides of the support part. The support part preferably has the same horizontal cross-sectional shape at the part above the pair of recesses and the part below the pair of recesses. In this way, by providing a chain insertion hole in the pole stand of the present invention, barricade tape can be used together with the chain.

[0013] It is preferable that the handle portion and the chain insertion hole have the same penetration direction, so that the barricade tape can be stretched across the handle portion and the side wall of the chain insertion hole at the same position in the thickness direction. Effect of the Invention

[0014] The pole stand of this invention makes it possible to hang cone bars while also securing space for attaching and hanging barricade tape. [Brief description of the drawings]

[0016] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0017] 1 is a perspective view showing a pole stand 100 according to one embodiment of the present invention. The pole stand 100 is used to hang cone bars CB or barricade tapes BT for preventing intrusion around no-entry areas or at the entrances of no-passage passages, and includes a support part 1 extending in a rod shape in a vertical direction V, a handle (handle part) 4 located V1 above the support part 1, a base 5 that is continuous with the lower end of the support part 1 and supports the support part 1, and a connection part 6 that connects the lower end of the support part 1 and the handle 4.

[0018] FIG. 2 is an exploded view of the support part 1 and the base 5 in the pole stand 100. The base 5 includes an insertion hole 51 extending in the vertical direction V and into which the lower end part 15 of the support part 1 is inserted. A groove 52 extending in the vertical direction V is provided in the side wall of the insertion hole 51. A groove 53 connected to the groove 52 and extending along the side wall is provided in the bottom of the insertion hole 51. When inserting the support part 1 into the base 5, the position of the protrusion 151 protruding horizontally from the lower end part 15 is aligned with the groove 52, and the support part 1 is inserted into the insertion hole 51. Next, when the protrusion 151 reaches the position of the groove 53, the support part 1 is rotated so that the protrusion 151 moves in the groove 53, so that the protrusion 151 does not move in the vertical direction V and the support part 1 does not come off the base 5.

[0019] The support part 1 is formed by balloon molding a resin such as high-density polyethylene into a hollow straight cylinder shape with a closed upper end and an open lower end. In the illustrated example, the support part 1 has a cylindrical shape, but is not limited to this and may have a polygonal prism shape.

[0020] FIG. 3 is a front view of the pole stand 100 in FIG. 1. FIG. 4 is an enlarged view of the range III shown in FIG. 3. As shown in FIGS. 1 to 4, the support 1 has a column 13 and a cone 14. The column 13 extends in a rod shape from the base 5 to the upper V1 in the vertical direction V. Hereinafter, the upper V1 of the vertical direction V may be simply referred to as the upper V1, and the lower V2 of the vertical direction V may be simply referred to as the lower V2. In the column 13, the diameter R1 in the horizontal direction H perpendicular to the vertical direction V is constant throughout the vertical direction V. The cone 14 is located at a position V1 above the column 13. The diameter R2 of the cone 14 in the horizontal direction H becomes smaller toward the upper V1. That is, the cone 14 has a conical or pyramidal shape. Typically, when the columnar portion 13 is cylindrical, the conical portion 14 has a conical shape, and when the columnar portion 13 is polygonal prism-shaped, the conical portion 14 has a pyramidal shape.

[0021] Specifically, the cone bar CB that is hung on the pole stand 100 includes a rod-shaped bar B and a ring-shaped hoop W provided at both ends of the bar B. The diameter R1 of the column portion 13 is larger than the inner diameter R3 of the hoop W. Typically, the diameter R2 of the cone portion 14 is the same as the diameter R1 of the column portion 13 at the lower end 142 that indicates the joint between the cone portion 14 and the column portion 13. That is, at the lower end 142 of the cone portion 14, the diameter R2 is larger than the inner diameter R3 of the hoop W. On the other hand, at the apex 141 that indicates the upper end of the cone portion 14, the diameter R2 is smaller than the diameter R1 and the inner diameter R3 of the hoop W. That is, the diameter R2 coincides with the inner diameter R3 of the hoop W at any point between the apex 141 and the lower end 142 of the cone portion 14. Therefore, the lower end 142 side of the cone portion 14 having a diameter R2 larger than the inner diameter R3 of the hoop W and the column portion 13 cannot pass through the hoop W of the cone bar CB. Therefore, the cone bar CB including the hoop W is hung on the cone portion 14.

[0022] The handle 4 is connected to the top 141 of the cone portion 14 via the connection portion 6. The handle 4 has a ring-like shape. That is, an opening M is formed in the handle 4. The opening M faces the horizontal direction H. By providing the handle 4 on the pole stand 100, the pole stand 100 becomes easier to grasp when transporting the pole stand 100, and the portability of the pole stand 100 is improved. For example, the handle 4 has a longitudinal shape in the vertical direction V. Therefore, in the pole stand 100, a space can be secured for wrapping and attaching the barricade tape BT1 around the handle 4 while passing it through the opening M (FIGS. 1 to 4).

[0023] Specifically, the handle 4 includes an arc-shaped portion 41 extending in a convex curve toward the upward direction V1, an arc-shaped portion 42 extending in a convex curve toward the downward direction V2, a straight extension portion 43a connecting one end of the arc-shaped portion 41 to one end of the arc-shaped portion 42, and a straight extension portion 43b connecting the other end of the arc-shaped portion 41 to the other end of the arc-shaped portion 42. The straight extension portion 43a and the straight extension portion 43b extend along the vertical direction V. By providing the straight extension portion 43a or the straight extension portion 43b, the contact surface of the handle 4 with the barricade tape BT1 can be configured to be flat, making it difficult for the barricade tape BT1 to peel off.

[0024] An outer diameter R4 of the handle 4 in the horizontal direction H is smaller than an inner diameter R3 of the loop W. Specifically, the distance from the outer peripheral surface of the straight extension portion 43a to the outer peripheral surface of the straight extension portion 43b is shorter than the inner diameter R3 of the loop W. Therefore, the handle 4 can easily pass through the inside of the loop W smoothly.

[0025] The shape of the handle 4 is not limited to the above, and may, for example, have a longitudinal shape in the horizontal direction H, may be circularly configured with only the arc-shaped portions 41 and 42, or may have a shape other than circular.

[0026] The connecting portion 6 connects the top 141 of the cone portion 14 and the arc-shaped portion 42 on the lower V2 side of the handle 4. The connecting portion 6 is a rod-like or plate-like member extending along the vertical direction V. Typically, the connecting portion 6 has a length in the vertical direction V that is at least equal to or greater than the width of the barricade tape BT. The length R5 of the connecting portion 6 in the horizontal direction H is smaller than the outer diameter R4 of the handle 4. Therefore, compared to when the barricade tape BT2 is wrapped around the pillar portion 13 and applied, less barricade tape BT2 is required and it can be easily wrapped and applied (FIGS. 1 to 4).

[0027] For example, the length R5 of the connecting portion 6 in the horizontal direction H is the same as the diameter of the apex 141 of the cone portion 14. Therefore, the hook W is less likely to get caught on the connecting portion 6 when the hook W is moved from the upper side V1 to the lower side V2, and when the hook W is moved from the lower side V2 to the upper side V1.

[0028] Furthermore, the relationship in length in the horizontal direction H between the conical portion 14, the connecting portion 6, and the handle 4 is not limited to the above; for example, the length of the connecting portion 6 may be greater than or equal to the length of the top 141 of the conical portion 14, and the length of the handle 4 may be less than or equal to the length of the connecting portion 6.

[0029] As shown in Figs. 1 to 4, the support part 1 has chain insertion holes 2A, 2B and locking bars 3A, 3B through which the chain A passes. The chain insertion holes 2A, 2B have the same configuration, and therefore will be representatively described below as the chain insertion hole 2. The locking bars 3A, 3B have the same configuration, and therefore will be representatively described below as the locking bar 3. Fig. 5 is an enlarged view of the main part showing the periphery of the chain insertion hole 2A in Fig. 4. Fig. 6 is an enlarged view of the main part showing the periphery of the chain insertion hole 2A in Fig. 4 as viewed from the side.

[0030] As shown in Fig. 6, the support part 1 has, at its upper end, a pair of rectangular recesses 11, 11 facing each other in the radial direction of the support part 1 (left and right direction in Fig. 6) in a side view, and a middle wall 12 separating the recesses 11, 11. As shown in Fig. 5, the middle wall 12 has, in the center in a front view, a chain insertion hole 2 connecting the pair of recesses 11, 11.

[0031] As shown in Fig. 5, the chain insertion hole 2 has a rounded rectangular shape with the longitudinal direction extending up and down in front view. As shown in Figs. 5 and 6, the recesses 11, 11 have a height equal to the full height of the chain insertion hole 2, are rectangular in front view and side view, extend perpendicularly and horizontally to the penetrating direction of the chain insertion hole 2, and are open at both ends to the sides (left and right direction in Fig. 5, and toward the depth of the paper in Fig. 6). The recess 11 is provided on its periphery with a border 11a with rounded corners.

[0032] The locking rod 3 is cylindrical with a spherical portion 3a at its tip and is hung vertically at the center of the bottom surface 2a of the chain insertion hole 2 in the direction in which the chain insertion hole 2 passes (left and right in Fig. 5) and the center in the width direction (left and right in Fig. 5). The locking rod 3 is hung vertically from the bottom surface 2a of the chain insertion hole 2 in this way, and is a straight rod that does not incline in either direction in the direction in which the chain insertion hole 2 passes. As a result, the chain link A1 of the locked chain A is unlikely to come out in either direction in the direction in which the chain insertion hole 2 passes.

[0033] In addition, even if the chain link A1 of the chain A inserted through the chain insertion hole 2 comes off the locking bar 3, the chain A is still locked in the chain insertion hole 2, and therefore the chain A does not come off the pole stand 100.

[0034] In addition, since the pole stand 100 has a recess 11 with both left and right ends open on the outside of the chain insertion hole 2, the chain A can be extended in a direction angled to the direction in which the chain passes through the chain insertion hole 2.

[0035] 7 is a diagram showing another example of how to attach the barricade tape BT3 to the pole stand 100. When attaching the barricade tape BT3 to the support part 1, the barricade tape BT3 is wound around the middle wall 12 while passing it through the chain insertion hole 2. In this way, by providing the chain insertion hole 2 in the pole stand 100, the barricade tape BT3 can be used together with the chain A.

[0036] As described above, the pole stand 100 of this embodiment includes the handle 4 and the connection part 6 in addition to the support part 1. The support part 1 is also provided with the cone part 14 on which the cone bar CB is hung. Therefore, the pole stand 100 can secure a space for attaching and hanging the barricade tape BT, while also hanging the cone bar CB.

[0037] In addition, since the handle 4 and the upper and lower chain insertion holes 2A and 2B penetrate in the same direction, it is preferable to stretch the barricade tape BT3 across them. This allows the barricade tape to be stretched across the handle and the side walls of the chain insertion holes at the same position in the front-to-back direction (depth direction in Figure 3), making for a beautiful appearance.

[0038] As described above, the pole stand of the present invention is not limited to the above-mentioned embodiment, and can be embodied in various forms without departing from the spirit of the invention. In addition, the components disclosed in the above-mentioned embodiment can be modified as appropriate. For example, some of the components shown in one embodiment may be added to the components of another embodiment, or some of the components shown in one embodiment may be deleted from the embodiment.

[0039] In addition, the drawings are mainly schematic illustrations of each component to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of drawing. In addition, the configurations of each component shown in the above embodiment are merely examples and are not particularly limited, and it goes without saying that various modifications are possible within a range that does not substantially deviate from the effects of the present invention.
