[0019] Hereinafter, a chained pole 10 according to one embodiment of the present invention will be described. As shown in FIG. 1 and FIG. 2, the chained pole 10 according to the present embodiment is linked to another chained pole 10A via a chain 8, and is used for purposes such as restricting the passage of vehicles and the entry of passersby, and guiding parking positions for vehicles.

[0020] The chained pole 10 according to the present embodiment is configured to include a pole 7 and a chain 8 provided so as to be extendable from the pole 7. The pole 7 includes a base plate 1 placed on an installation surface, a pole support portion 6 rotatably assembled to the base plate 1, a pole body 71 fixed to the pole support portion 6, and the like. Each configuration will be described in detail below.

[0021] The base plate 1 is a circular metal plate material having a space on the lower surface. A magnetic member 2 is fixed in the space on the lower surface of the base plate 1 (see FIG. 4 and FIG. 5). The magnetic member 2 enables the base plate 1 to be attracted to an iron member. That is, the chained pole 10 can be stably placed on a laying iron plate or the like by the base plate 1 to which the magnetic member 2 is fixed.

[0022] A pole support 6 is rotatably assembled to the base plate 1 via a connecting base 3, a connecting bolt 4, and a rotating part 5. The connecting base 3 is fixed to the upper surface of the base plate 1. The rotating part 5 is rotatably connected to the connecting base 3, with the connecting bolt 4, which is installed parallel to the base plate 1, as the central point. This allows the connection angle of the rotating part 5 to the connecting base 3 to be adjusted to the angle desired by the user.

[0023] The pole support portion 6 is fixed to the upper side of the rotating portion 5 and extends in a direction intersecting the base plate 1. The pole support portion 6 is a metal member formed in a hollow cylindrical shape, and the lower end of the pole body 71 is inserted inside it. As a result, the pole body 71 is connected to the base plate 1 so as to be rotatable around a pivot axis (connecting bolt 4) that is parallel to the base plate 1. This allows the user of the chain pole 10 to adjust the angle of the pole body 71 relative to the base plate 1. Therefore, even when the base plate 1 is placed on an inclined surface, the chain pole 10 can be erected with the pole body 71 facing vertically.

[0024] The pole body 71 is a cylindrical member formed from synthetic resin or the like. The pole body 71 has two small-diameter sections with a smaller outer diameter than the rest of the pole. Reflective materials 72, 72 made of a material with high light reflectivity are provided on each of these small-diameter sections. An upper reflective material 73 is also provided at the upper end of the pole body 71. Commercially available reflective tape can be used for the reflective materials 72 and the upper reflective material 73.

[0025] According to the chain-attached pole 10 of this embodiment, by providing a reflective material 72 and an upper reflective material 73 on the pole body 71, visibility can be improved even in dark usage conditions such as at night. Furthermore, by providing the reflective material 72 on the small diameter portion of the pole body 71, contact with the reflective material 72 from the outside can be reduced, thereby preventing scratches and dirt from getting on the reflective material 72.

[0026] Hook portions 74, 74 are formed on the upper part of the pole body 71. As shown in Figures 1 and 2, the hook portions 74 can be engaged with the engaging members 84 of other chain-equipped poles 10. This makes it possible to link the chain-equipped pole 10 with other chain-equipped poles via the chain 8.

[0027] In the chain-attached pole 10 according to this embodiment, the hook portions 74-74 are assembled to the pole body 71 so as to be rotatable in the circumferential direction. This makes it possible to orient the hook portions 74-74 toward the other chain-attached pole.

[0028] Furthermore, in the chain-attached pole 10 according to this embodiment, the hook portions 74-74 are formed inward from the outer circumferential surface of the pole body 71 when viewed in the axial direction of the pole body 71. That is, since the hook portions 74-74 do not protrude outward, interference between the hook portions 74-74 and other components can be prevented when transporting and using the chain-attached pole 10.

[0029] As shown in Figures 2, 4, and 5, a circular opening 75 is formed on the upper part of the outer circumferential surface of the pole body 71, connecting the inside and outside of the pole body 71. A chain 8 is inserted through the opening 75.

[0030] As shown in Figures 4 and 5, the chain 8 is movable forward and backward through the opening 75, with its base end (the lower end shown in Figure 4) housed inside the pole body 71 and its tip end (the upper end shown in Figure 4) extending outside the pole body 71. This allows the chain 8 to transition between a housed state, as shown in Figure 4, where it is housed inside the pole body 71, and a usable state, as shown in Figure 5, where it is extended.

[0031] As shown in Figure 4, the chain 8 is composed of a chain body 81 made up of many chain elements connected together from annular members made of resin, a restricted member 83 provided at the base end of the chain 8, and an engaged member 84 provided at the tip of the chain 8.

[0032] In the pole 10 with a chain according to this embodiment, the displacement of the chain 8 through the opening 75 at the base end is restricted by the restricting member 83. The restricting member 83 is made of an elastic material such as synthetic rubber.

[0033] As shown in Figure 5, the restricted member 83 is formed in a frustoconical shape, having a first base surface 83a that is smaller in diameter than the opening 75 and a second base surface 83b that is larger in diameter than the opening 75. Since the second base surface 83b cannot pass through the opening 75, the displacement of the pole body 71 from the inside to the outside through the opening 75 at the base end of the chain 8 is restricted.

[0034] When inserting the restricted member 83 into the pole body 71, the small-diameter first bottom surface 83a is inserted from the outside of the opening 75, and the restricted member 83 is pushed in while elastically deformed. After the restricted member 83 is inserted into the pole body 71, it does not pass through the opening 75 in order for the restricted member 83 to return to its original shape.

[0035] The base end of the chain body 81 is connected to the first bottom surface 83a of the restricted member 83 via a connecting member 82a. In this embodiment, the connecting member 82a is made capable of releasing the connection between the first bottom surface 83a and the base end of the chain body 81. This allows the chain body 81 and the rest of the chain to be replaced without replacing the restricted member 83. In other words, the length, color, material, etc., of the chain body 81 can be easily replaced in the chain-equipped pole 10.

[0036] As shown in Figures 1, 3, and 4, in the chain-attached pole 10 according to this embodiment, the engaged member 84, which is a resin member, is formed to include a main body portion 84a, a connecting portion 84b, a cover portion 84c, and an engaged portion 84d.

[0037] In the engaged member 84, the main body portion 84a is formed in a cylindrical shape so that it can be inserted into the opening 75 of the pole body 71. An annular projection is formed around the main body portion 84a to prevent it from coming out of the opening 75.

[0038] In the engaged member 84, the connecting portion 84b is formed in a U-shape at one end of the main body portion 84a and is connected to the tip of the chain body 81 via a second connecting member 82b. In this embodiment, the second connecting member 82b is made capable of releasing the connection between the connecting portion 84b and the tip of the chain body 81. This makes it possible to easily replace the engaged member 84 in the chain 8 when the engaged member 84 wears out.

[0039] In the engaged member 84, the lid portion 84c is a plate-like portion provided at the other end of the main body portion 84a. The lid portion 84c is formed to be larger than the opening 75, so that the opening 75 can be closed when the main body portion 84a is inserted into the opening 75.

[0040] As shown in Figures 3(a) and (b), the cover portion 84c is formed in a curved plate shape that conforms to the outer surface of the pole body 71. This allows the cover portion 84c to be tightly fitted to the outer surface of the pole body 71 when the main body portion 84a is inserted into the opening 75, as shown in Figure 4. In other words, it is possible to enhance the aesthetic design of the pole 10 with the chain attached when the chain 8 is housed in the pole body 71. Furthermore, when the chain 8 is housed in the pole body 71, it is possible to prevent rain, soil, dust, etc. from entering the inside of the pole body 71 through the opening 75.

[0041] In the engaged member 84, the engaged portion 84d is a ring-shaped projection formed on the lid portion 84c on the side opposite to the main body portion 84a. As shown in Figures 1 and 2, in the engaged member 84, the engaged portion 84d is capable of engaging with the hook portion 74 of the pole body 71.

[0042] Furthermore, in the engaged member 84, the engaged portion 84d can be made hook-shaped instead of ring-shaped. This allows the engaged member 84 to engage not only with the hook portion 74 but also with wire mesh or other chains. Additionally, by providing a magnetic member to the engaged member 84, it is possible to configure the engaged member 84 to be attracted to iron doors or the like.

[0043] In the chain-attached pole 10 according to this embodiment, the engaged member 84 can be attached to the pole body 71 by inserting the connecting portion 84b and the main body portion 84a from the outside of the opening 75, as shown in Figure 4, and closing the opening 75 with the cover portion 84c.

[0044] As a result, when storing or transporting the pole body 71 with the chain 8 housed inside, the chain 8 will not fall out of the pole body 71 even when subjected to external forces such as gravity. In other words, according to the chain-equipped pole 10 of this embodiment, it is possible to stably maintain the state in which the chain 8 is housed inside the pole body 71.
