Description

[Technical field]

[0001] The present invention relates to a magnetic pole used, for example, to restrict the passage of vehicles or the intrusion of pedestrians, or to guide a vehicle to a parking position. [Background technology]

[0002] Conventionally, a magnet pole has been known in which a yoke consisting of a cylindrical portion and a top portion is disposed in a recess formed by the lower portion of a cylindrical body and a partition wall, a magnet is magnetically attracted to the top portion of the yoke, and a protective plate is attached to the underside of the magnet (see, for example, Patent Document 1).

[0003] Furthermore, for example, with the aim of preventing the intrusion of vehicles or the like, a chain-connecting pole is known which uses a plurality of poles and is configured to connect the poles with a chain (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-118159 A [Patent Document 2] Utility Model Registration No. 3154693 Summary of the Invention [Problem to be solved by the invention]

[0005] As disclosed in Patent Document 1, when a magnet is provided at the bottom of the cylinder that constitutes the magnet pole and configured to be magnetically attracted to an installation base made of an iron plate attached to the road surface or the like, the magnet pole can be easily and quickly attached and removed. However, the installation surface of the magnet pole is not necessarily horizontal, and when the installation surface is inclined, the erection direction of the magnet pole becomes obliquely perpendicular to the inclined surface, which causes a problem that a stable installation state cannot be obtained.

[0006] In order to prevent the above-mentioned situation from occurring, it is possible to provide an angle adjustment unit that changes the connection angle of the pole part relative to the base plate on which the magnet is provided, thereby adjusting the erection direction of the pole part. However, when this configuration is applied to the chain connection pole disclosed in Patent Document 2, the inclination direction of the pole part relative to the base plate and the direction of the chain locking part provided on the pole cannot be properly matched. In this case, the tension direction of the chain stretched between the adjacent pole parts may become unnatural. In addition, when force is applied to the chain, a rotational force around the axis may be generated in the pole, making the installation state of the pole unstable, and the design of the pole and the chain is also poor.

[0007] The object of the present invention is to provide a magnet pole which allows the pole portion to always be erected at an appropriate angle relative to the installation surface even when the installation surface is inclined, and which allows a cable body consisting of a chain or the like to be tensioned in an appropriate state. [Means for solving the problem]

[0008] A magnet pole according to one example of the present invention comprises a base plate, a magnetic member fixed to the underside of the base plate, a connecting base assembled to the upper surface of the base plate, a rotating part connected to the connecting base so as to be rotatable around a rotation axis parallel to the base plate, and a pole part assembled to the upper side of the rotating part and extending in a direction intersecting the base plate, wherein two hook parts to which a cable is engaged are formed in positions facing each other on the pole part, and the hook parts are rotatable in the circumferential direction of the pole part relative to the rotating part. Effect of the Invention

[0009] When the magnet pole configured as described above is installed on an inclined surface, the pole part can be always erected at an appropriate angle to the installation surface by rotating the rotating part around the rotation axis and adjusting the connection angle with the connection base. Also, when multiple magnet poles are installed on an inclined surface and a cable made of a chain or the like is stretched between adjacent magnet poles, the hook part can be rotated relative to the rotating part to change the orientation of the hook part so that the cable can always be stretched in an appropriate state.

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals are used to denote the same configuration, and the description thereof will be omitted.

[0012] 1 to 3 show a magnet pole according to one embodiment of the present invention. This magnet pole includes a base plate 1 placed on an installation surface, a magnetic member 2 made of a neodymium magnet or the like fixed to the lower surface of the base plate 1, a connecting base 3 attached to the upper surface of the base plate 1, a rotating part 5 connected to the connecting base 3 so as to be rotatable about a rotating shaft 41 made of a shaft of a connecting bolt 4 installed in parallel to the base plate 1, and a pole part P attached to the upper side of the rotating part 5 and extending in a direction intersecting the base plate 1.

[0013] 3, the base plate 1 is made of, for example, a steel plate material and is formed in a dish shape having a circular top plate 11 and a peripheral wall 12 extending downward. The magnetic member 2 has a thickness and diameter that allows it to be accommodated within the base plate 1, and is fixed to the underside of the top plate 11 via fixing bolts 21. Note that instead of the fixing bolts 21, the magnetic member 2 can also be fixed to the underside of the base plate 1 with an adhesive or the like.

[0014] The connecting base 3 has a bottom plate 31 which is assembled to the upper surface of the base plate 1 by means such as welding, and a pair of left and right side plates 32, 32 extending upward from the side ends of the bottom plate 31, and the side plates 32, 32 have an insertion hole through which the rotating shaft 41 is inserted.

[0015] The rotating part 5 has a pair of left and right side plates 51, 51 arranged between the side plates 32, 32 of the connecting base 3, and a top plate 52 connecting the upper ends thereof, and an insertion hole through which the rotating shaft 41 is inserted is formed in the side plates 51, 51. The rotating shaft 41 formed of the shaft portion of the connecting bolt 4 is inserted into the insertion holes of the side plates 32, 32 of the connecting base 3 and the side plates 32, 32 of the rotating part 5, and a spacer 42 is fitted onto the rotating shaft 41. In this state, a nut 43 is screwed onto the tip of the rotating shaft 41, so that the connecting base 3 and the rotating part 5 are connected to be relatively rotatable about the rotating shaft 41, and the connecting angle of the rotating part 5 to the connecting base 3 can be adjusted to an angle desired by the user.

[0016] The pole portion P comprises a base portion 6 which is assembled to the rotating portion 5, an intermediate body 7 which extends above the base portion 6, and a tip portion 8 which extends above the base portion 6 and is assembled to the intermediate body 7 so as to be rotatable in the circumferential direction of the pole portion P.

[0017] The base 6 of the pole part P is formed of, for example, a steel plate material or the like into a bottomed cylindrical body having a bottom plate 61. The bottom plate 61 of the base 6 is fixed to the top plate 52 of the rotating part 5 via a fastener having a fixing bolt 62, a nut 63, or the like. In addition, a rubber damping material 64 is arranged on the threaded shaft of the fixing bolt 62 that fixes the lower end of the pole part P to the top plate 52 of the rotating part 5, sandwiched between a pair of upper and lower washers.

[0018] The intermediate body 7 of the pole part P is formed of, for example, a synthetic resin material, and has a cylindrical shape including a cylindrical part 71 inserted into the upper part of the base 6, a partition wall part 72 extending above the cylindrical part 71, a large diameter part 73 extending above the partition wall part 72, and a small diameter part 74 extending above the partition wall part 72. As shown in FIG. 3, an annular upper wall part 75 is provided at the upper end of the small diameter part 74, and a recessed groove 76 extending in the circumferential direction of the pole part P is formed on the outer circumferential surface of the small diameter part 74 located below the upper wall part 75. The cylindrical part 71 of the intermediate body 7 is connected to the upper part of the base 6 via a connecting pin 77 in a state where it is inserted, so that the intermediate body 7 is assembled to the base 6 and the base plate 1 in a non-rotatable state.

[0019] 1 and 2, in this embodiment, a pair of upper and lower large diameter portions 73, 73 and small diameter portions 74, 74 are provided on the intermediate body 7. A reflective material (not shown) made of a material with high light reflectance is provided on the outer circumferential surface of each small diameter portion 74 as necessary. This reflective material is preferably colored differently from the large diameter portion 73.

[0020] The tip 8 of the pole part P is made of, for example, the same material as the intermediate body 7, and the lower part that is fitted onto the intermediate body 7 has a cylindrical part 81, a thin diameter part 82 extending upward from the upper surface of the central part, a large diameter part 83 provided on the upper part, a small diameter part 84 extending upward, and a large diameter cap part 85 provided on the upper part. The outer circumferential surface of the small diameter part 84 is made of a material with high light reflectivity like the small diameter part 74 of the intermediate body 7, and a reflective material (not shown) colored in a color different from the large diameter part 83 and the cap part 85 is provided as necessary.

[0021] As shown in FIG. 3, an annular partition wall 86 corresponding to the upper wall 75 of the intermediate body 7 is provided on the inner peripheral surface of the cylindrical portion 81, and below the partition wall 86, a protruding strip 87 corresponding to the recessed groove 76 of the intermediate body 7 is formed so as to extend in the circumferential direction of the pole portion P. The cylindrical portion 81 of the tip portion 8 is fitted onto the upper end of the small diameter portion 74 formed on the upper side of the intermediate body 7. At this time, as shown in FIG. 3, the protruding strip 87 formed on the inner peripheral surface of the cylindrical portion 81 is fitted into the recessed groove 76 formed on the outer periphery of the small diameter portion 74 on the upper side of the intermediate body 7. This prevents the tip portion 8 from coming off the intermediate body 7, and allows the tip portion 8 to rotate in the circumferential direction of the pole portion P relative to the intermediate body 7 and the base portion 6.

[0022] 1 and 2, a pair of hook portions F, F are provided at the upper end of the tubular portion 81 at positions facing each other with the thin-diameter portion 82 in between. The hook portion F functions as a locked portion to which a cord body, which will be described later, is locked. The upper portion of the hook portion F is inclined so as to face inward from the outer circumferential surface of the pole portion P when viewed in the axial direction of the pole portion P, so that the end of the cord body locked to the hook portion F is configured to be difficult to come loose.

[0023] The magnet pole constructed as described above is used in a state where the base plate 1 is placed on a mounting plate T made of iron or the like that is fixed to the mounting surface, and the base plate 1 is magnetically attached to the mounting plate T in response to the magnetic force of the magnetic member 2 fixed to its underside, as shown in Fig. 3. For example, if the mounting surface of the magnet pole is a horizontal plane, the connecting angle between the connecting base 3 and the rotating part 5 is adjusted so that the pole part P is perpendicular to the base plate 1, and then the two are fixed together with a connecting bolt 4, so that the pole part P is erected vertically.

[0024] On the other hand, as shown in Figure 4, when the installation surface of the magnet pole is an inclined surface inclined at a predetermined angle, the base plate 1 is placed on the mounting plate T fixed to the inclined surface with the rotation axis 41 facing in a direction perpendicular to the paper surface of Figure 4, and the magnetic member 2 is magnetically attracted to the mounting plate T in accordance with the magnetic force of the magnetic member 2.

[0025] Next, the rotating part 5 is rotated about the rotation shaft 41, and the connection angle between the connecting base 3 and the rotating part 5 is adjusted so that the pole part P faces vertically. In this way, the magnet pole according to this embodiment can always stand the pole part P at an appropriate angle (so that the pole part P faces vertically) with respect to the installation surface by adjusting the connection angle between the connecting base 3 and the pole part P by rotating the rotating part 5 about the rotation shaft 41.

[0026] Furthermore, as shown in Figure 4, when multiple magnet poles are sequentially arranged at different height positions along an inclined surface and a cable S made of a plastic chain or rope or the like is stretched between adjacent pole sections P, the orientation of each hook section F can be adjusted so that the cable S can be engaged with the hook section F in the appropriate state (a state in which the cable S extends in the direction in which the magnet poles are arranged) by rotating and displacing the tip 8 of the pole section P provided with the hook section F relative to the intermediate section 7 or the like located below.

[0027] For example, if a pair of hooks F provided on the pole P are arranged in a direction perpendicular to the paper surface of FIG. 4, that is, in a direction perpendicular to the arrangement direction of each pole P, it is inevitable that the cable S will be locked by the hooks F in a twisted and unnatural state. In such a case, by rotating and displacing the tip 8 of the pole P and adjusting the direction of the hooks F to match the arrangement direction of each pole P, it is possible to reliably prevent the cable S from being twisted. In addition, even if a force is applied to the cable S, no rotational force is generated around the axis of the pole P, so that the possibility of the installation state of the pole P becoming unstable can be reduced. In addition, it is possible to improve the design of the magnet pole.

[0028] As shown in Figure 5, even when multiple magnet poles are sequentially arranged at the same height on an inclined installation surface and a cable S consisting of a chain or the like is stretched between adjacent pole sections P, the orientation of each hook section F can be changed so that the cable S can be stretched in the appropriate state by rotating and displacing the tip 8 of the pole section P, which is provided with a hook section F, relative to an intermediate section 7 or the like located below.

[0029] Furthermore, as shown in Figure 6, even when multiple magnet poles are arranged in a ring shape at the same height position and different height positions on an inclined installation surface, and a cable S consisting of a chain or the like is stretched between adjacent pole sections P, the orientation of each hook section F can be changed so that the cable S can be stretched in the appropriate state by rotating and displacing the tip 8 of the pole section P provided with the hook section F relative to the intermediate body 7 and base section 6 located below it.

[0030] In the above-described embodiment, the pole portion P comprises a base 6 fixed to the rotating portion 5 via a fixing bolt 62, an intermediate body 7 non-rotatably connected to the base 6, and a tip portion 8 assembled to the intermediate body 7 so as to be rotatable in the circumferential direction of the pole portion P, and a hook portion F is provided on the tip portion 8. Therefore, by slidingly rotating the lower part of the tip portion 8 in the circumferential direction relative to the upper part of the intermediate body 7, the hook portion F provided on the tip portion 8 can be smoothly rotated and displaced, and the orientation of each hook portion F can be easily and appropriately changed.

[0031] Instead of the above-mentioned configuration, for example, the bottom plate 61 provided on the base 6 of the pole P can be rotated and displaced in the circumferential direction around the fixing bolt 62 relative to the top plate 52 of the rotating part 5, thereby rotating the pole P as a whole and adjusting the orientation of the hook part F. In this case, a bearing member can be inserted between the bottom plate 61 and the top plate 52. In this configuration, the work of adjusting the orientation of the hook part F is somewhat more complicated than in the above-mentioned embodiment, but there is an advantage that the pole part P can be integrated without being divided into the base part 6, the tip part 8, etc., and the structure can be simplified.

[0032] Also, the hook portion F to which the cord S is engaged can be configured to protrude outward from the outer circumferential surface of the pole portion P when viewed in the axial direction, but in this case, it is unavoidable that the hook portion F gets in the way when the magnet pole is transported and used. For this reason, in order to prevent the hook portion F from getting in the way, it is preferable to form the hook portion F so as to be positioned inward from the outer circumferential surface of the pole portion P when viewed in the axial direction, as in this embodiment.

[0033] Furthermore, when a reflective material is provided at least at one location on the pole P, the presence of the magnet pole can be brought to the attention of pedestrians and vehicle occupants, thereby increasing the useful value of the magnet pole. In particular, as shown in the above embodiment, by providing small diameter parts 74, 83 having an outer diameter smaller than that of other parts of the pole P and arranging a reflective material on the small diameter parts 74, 83, there is an advantage that the reflective material can be prevented from coming into contact with obstacles when the magnet pole is in use, and damage to the reflective material can be effectively prevented.

[0034] In the above embodiment, since the rubber damping material 64 is interposed between the rotating part 5 and the pole part P, specifically, on the screw shaft of the fixing bolt 62 as shown in Fig. 3, when the magnet pole is installed on a road, it is possible to suppress the vibration of the road surface from being transmitted from the base plate 1 to the upper part of the pole part P, thereby preventing the pole part P from wobbling. Note that the position where the damping material 64 is interposed is not limited to between the rotating part 5 and the pole part P, and it is also possible to place it between the base plate 1 and the connecting base part 3, for example.
