  However, in the conventional example shown in Patent Document 1, the portion where the antenna portion is attached to the heel, that is, the portion where the ridges protruding outward on both sides of the antenna element body are fixed with screws are exposed on the front side of the heel, Moreover, it protrudes on both the left and right sides.

  Moreover, the part which attaches a transmission-line trap part to a collar, ie, the part which fixes the joining pieces which protruded up and down of the half-divided body with a screw, is exposed to the front side of a collar.

  Thus, since the part which fixes ridges with a screw and the part which fixes joining pieces with a screw are exposed to the front side of a heel, an external appearance is bad.

  In particular, there is a problem that a person or an object is easily caught because a portion where the heels are fixed with screws protrudes to the left and right sides and is exposed.

  An object of the present invention is to provide an antenna device and a scissor with an antenna device that can be mounted so that a mounting portion to the scissors is not exposed.

The antenna device of the present invention includes an antenna plate bent in an arc shape so as to be able to cover a part of the outer peripheral surface of a cylindrical bag, and a non-conductive material protruding from the back surface of the antenna plate.

And the heel mounting portion is rotatably attached to the outer periphery of the cylindrical heel in the circumferential direction, and the antenna plate covers a portion of the outer peripheral surface of the heel in the circumferential direction, The antenna plate is configured to allow rotation of the antenna plate with respect to the flange by a predetermined angle in a state where the flange attachment tool is positioned between the left and right edges of the antenna plate having a circular arc cross section. characterized Rukoto gap dimension between the left and right ends are set To.

  In the present invention, since the flange mounting portion protrudes from the back surface of the antenna plate, the flange mounting portion is hidden by the antenna plate with the flange mounting portion mounted on the flange, and is not exposed to the front side of the flange. It is difficult to damage the appearance, and it is difficult for people and objects to get caught on the heel mounting part. In addition, since the heel mounting portion is non-conductive, the heel mounting portion hardly influences the antenna performance of the antenna plate even though the heel mounting portion protrudes from the back surface of the antenna plate.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 shows an embodiment of an antenna device 4. The antenna device 4 includes an antenna plate 2 and a hook attachment portion 3 protruding from the back surface of the antenna plate 2.

  The antenna plate 2 includes a main body portion 10 bent so as to cover a part of the outer peripheral surface of the flange 1 and an antenna portion 11 for receiving a television signal provided in the main body portion 10. Yes.

  The main body 10 is formed in a substantially arc shape in cross section so as to cover a part of the outer peripheral surface of the cylindrical basket 1. In the case of an example in which the antenna plate 2 covers a part in the circumferential direction of the outer peripheral surface of the rectangular tube-shaped ridge 1, the main body portion 10 is formed in a substantially U-shaped cross section.

  In the embodiment, the main body 10 is made of a nonconductive material such as a nonconductive synthetic resin.

  The antenna unit 11 is embedded or laminated in the main body unit 10. In the embodiment of FIG. 1, an example is shown in which the antenna portion 11 is integrally embedded in a main body portion 10 made of synthetic resin.

  The antenna unit 11 of the embodiment shown in FIG. 1 shows an example of a slot antenna, and is formed by providing an elongated slot 13 on a thin metal plate 12 (including a metal foil) having a conductive vertically long rectangular shape. .

  Further, in the embodiment of FIG. 1, a plurality of slots 13 of the metal plate material 12 are provided side by side in the vertical direction, and adjacent slots 13 are connected by a narrow groove 14. Each slot 13 is formed in a bow tie shape in which the vertices of a triangle are abutted with each other.

  The antenna unit 11 includes a first receiving unit 15 that receives radio waves in a first frequency band (for example, 473 to 600 MHz) and a second receiving unit that receives radio waves in a second frequency band (for example, 600 to 720 MHz). 16.

  The first receiving unit 15 includes a slot 13 and a peripheral portion of the slot 13. The second receiving portion 16 is constituted by a metal plate 12 portion adjacent to the slot 13 in the vertical direction.

  The length in the vertical direction of the slot 13 constituting the first receiving unit 15 is determined corresponding to the length of the electrical half wavelength of the radio wave in the first frequency band. Further, the circumferential length of the second receiving unit 16 is determined in correspondence with the length of the electrical half-wavelength of the radio wave in the second frequency band.

  The apex portions of the triangles on both sides of the slot 13 of the metal plate 12 are the power feeding portions 17 respectively. A power supply cable (not shown) is connected to the power supply unit 17.

  The eaves mounting portion 3 protruding from the back surface of the main body portion 10 is made of a nonconductive material such as a synthetic resin.

  The heel mounting portion 3 may be partly or entirely formed integrally with the main body portion 10, or the heel mounting portion 3 is formed separately from the main body portion 10, and is a fixture such as an adhesive or a screw. It may be fixed to the back surface of the main body 10 by any fixing means such as fixing by locking.

  The eaves attaching portion 3 is formed of a nonconductive material such as a nonconductive synthetic resin. The scissor mounting portion 3 is configured by connecting one end portions of a pair of half bodies 18 so as to be rotatable by a bearing portion 19, and is connected to a locking portion 20 at the other end portion of the pair of half bodies 18. The locking part 21 is freely lockable. In the embodiment of FIG. 1C, an example of a substantially semicircular half 18 is shown.

  The antenna device 4 having the above-described configuration is attached to the cage 1 attached to the outer wall 5 of the building as shown in FIG.

  The scissors 1 have a cylindrical cross section or a square cross section, and are attached to the outer wall 5 by a scissor attachment 6.

  As shown in FIG. 3, the scissor attachment 6 includes a scissor support part 7 that supports the outer periphery of the scissors 1, an outer wall fixing part 8 for fixing to the outer wall 5, and a scissor support part 7. A connecting portion 9 that connects the outer wall fixing portion 8 is provided.

  The heel support portion 7 is configured by connecting one end portions of a pair of heel support halves 22 so as to be rotatable by a bearing portion, and a locking portion at the other end of the pair of heel support halves 22 The locked portion is freely lockable.

  The scissor fixture 6 has the outer wall fixing part 8 fixed to the outer wall 5 and the locking part and the locked part are locked in a state where the outer periphery of the scissors 1 is surrounded by a pair of scissors support halves 22. Then, the heel 1 is supported.

  The scissors fixture 6 is usually fixed to the outer wall 5 at a pitch of 1 m in the vertical direction. In addition, in the strong wind region, the kite fixture 6 is fixed to the outer wall 5 in the vertical direction at a pitch of 85 cm.

  As described above, the antenna plate 2 is attached later to the flange 1 attached to the outer wall 5. In this case, the casket 1 may be the casket 1 newly constructed by new construction or reconstruction, or may be any existing construction that has elapsed since the new construction or reconstruction.

  When mounting the antenna plate 2, the locking portion 20 and the locked portion 21 are locked with the pair of halves 18 surrounding the outer periphery of the arbitrary position in the vertical direction of the flange 1, as shown in FIG. Thus, the antenna plate 2 is attached to the flange 1 by strongly tightening the outer periphery of the flange 1 with the pair of halves 18.

  In this way, the hook mounting portion 3 protruding from the back surface of the main body 10 is attached to the hook 1 and the antenna plate 2 is attached to the hook 1, so that the hook mounting portion 3 is hidden by the main body 10 and the hook 1 is attached. It is not exposed to the front side of the, and the appearance is difficult to be damaged. In addition, since the heel mounting portion 3 does not protrude to the left or right side of the antenna plate 2, it is difficult for people or objects to be caught on the heel mounting portion 3.

  Further, since the heel mounting portion 3 is non-conductive, the heel mounting portion 3 hardly affects the antenna performance of the antenna plate 2 even though the heel mounting portion 3 protrudes from the back surface of the antenna plate 2.

  Here, when the rod 1 is cylindrical, the rod attachment portion 3 is attached to the outer periphery of the rod 1 so as to be rotatable in the circumferential direction, and the rod attachment portion 3 is rotated in the circumferential direction of the rod 1. Thus, the direction of the antenna plate 2 can be changed, and the reception direction of the antenna plate 2 can be adjusted.

  When the orientation of the antenna plate 2 is adjusted, the hook attaching portion 3 is rotated in a state where the locking of the locking portion 20 and the locked portion 21 is released, and the locking portion 20 is adjusted after the reception direction is adjusted. And the to-be-latched part 21 is latched and the outer periphery of the collar 1 is strongly tightened by the pair of halves 18.

  As a result, the antenna plate 2 can be easily mounted at an arbitrary position in the vertical direction of the rod 1 and in the state facing the best reception direction according to the site. The facing state is easily maintained and the downward shift is suppressed.

  As described above, the antenna plate 2 is mounted at an arbitrary position in the vertical direction of the rod 1, and further, the lower end of the upper rod mounting portion 3 as shown in FIG. 7 is attached so that it hits the upper end of 7, and the upper end of the lower hook attaching part 3 is preferably attached so as to hit the lower end of the hook supporting part 7 of another hook attaching tool 6.

  In this case, the connecting portion 6 of the saddle fitting 6 is located in the gap between the left and right edges of the antenna plate 2 having a cross-sectional arc, and the antenna plate 2 having a circular arc cross-section can be attached without being obstructed by the saddle fixture 6. It is done.

  In this example, since the lower end of the upper hook mounting portion 3 hits the upper end of the hook support portion 7, the upper hook mounting portion 3 is more reliably prevented from shifting downward and the antenna plate 2 is shifted downward. hard. In addition, since the upper end of the lower hook mounting portion 3 hits the lower end of the hook support portion 7 of another hook mounting tool 6, it is possible to prevent the lower hook mounting portion 3 from being displaced upward by strong winds or the like. The plate 2 is difficult to shift upward.

  In order to attach the antenna plate 2 in this way, the length dimension M between the upper and lower hook mounting portions 3 shown in FIG. 1 is set to a length corresponding to the fixed pitch of the upper and lower hook mounting tools 6.

  That is, in the normal area, the fixing pitch of the saddle fitting 6 is 1 m, and in the strong wind area, the fixing pitch of the saddle fitting 6 is 85 cm. Therefore, the dimension M is determined corresponding to the construction area.

  FIGS. 1 and 3 show examples in which the length dimension M between the upper and lower hook attachment portions 3 is set to a length corresponding to a normal area where the fixing pitch of the hook attachment 6 is 1 m, and FIG. This is an example in which the fixed pitch of the scissors fixture 6 is set to a length corresponding to a strong wind area of 85 cm.

  Even if the upper and lower heel mounting portions 3 hit against the corresponding heel support portions 7 so as not to be displaced up and down, the upper and lower heel mounting portions 3 are rotated by a predetermined angle in the circumferential direction of the heel 1. It is possible to change the direction of the antenna plate 2.

  For this reason, the gap dimension between the left and right end edges of the antenna plate 2 having a circular arc cross section is such that the saddle attachment 6 is positioned in the gap between the left and right end edges of the antenna plate 2. The clearance dimension is set so as to allow the rotation of a predetermined angle based on the rotation with respect to 1.

  The rotation at the predetermined angle refers to the state in which the left end of the antenna plate 2 shown in FIG. 5A is in contact with the connecting portion 9 of the hook attachment 6 and the right end of the antenna plate 2 shown in FIG. It is a rotation angle until it hits the connection part 9 of the eaves fixture 6.

  An example of the rotation angle is ± 45 ° in the left-right direction. In this example, the opening angle between the left and right edges of the antenna plate 2 having a circular arc cross section is 90 °. Of course, the opening angle between the left and right edges of the antenna plate 2 is not limited to 90 °.

  The scissor mounting portion 3 of the above example is an example of a configuration in which the other end portion of a pair of halves 18 whose one end portions are rotatably connected by a bearing portion 19 is provided with a locking portion 20 and a locked portion 21. However, the heel mounting portion 3 is not limited to this example.

  For example, although not shown in the drawings, the hook attaching portion 3 is provided with connecting pieces at the other end portions of the pair of half bodies 18 whose one ends are rotatably connected to each other by the bearing portion 19. It is also possible to use a configuration in which the screw is tightened.

  Moreover, although illustration is abbreviate | omitted, the structure which provides a connection piece in the both ends of a pair of half body 18 respectively, and fastens the connection pieces of both sides with a screw may be sufficient.

  In the example of tightening with these screws, the pair of half bodies 18 can be strongly tightened to the heel 1, and the state in which the best receiving direction is oriented can be more reliably secured by tightening the screws strongly after adjusting the receiving direction. It is maintained and the downward shift is suppressed more reliably.

  In the embodiment of FIG. 1, an example in which the antenna unit 11 is embedded in the main body unit 10 is shown.

  Further, in the embodiment of FIG. 7, an example is shown in which the main body portion 10 is configured by combining and combining a front surface side cover 26 and a separate back surface side cover 27.

  In this example, the front side cover 26 is formed of an electrically insulating material such as an electrically insulating synthetic resin in an arc shape in cross section, and a wall portion 28 projects from the outer peripheral edge portion toward the back, and further includes a plurality of engagement members. A pawl 29 is projected.

  The back surface side cover 27 is formed in an electric insulating material such as an electrically insulating synthetic resin in an arc shape in cross section, and has a size that fits in a portion surrounded by the wall portion 28 on the back surface of the front surface side cover 26. Further, a plurality of locking holes 30 are formed.

  The antenna unit 11 is disposed in a portion surrounded by the wall portion 28 on the back surface of the front side cover 26. Furthermore, the back surface side cover 27 is disposed in a portion surrounded by the wall portion 28 on the back surface of the front surface side cover 26 via the antenna portion 11, and the locking claw 29 is locked to the locking hole 30, thereby The side cover 26 and the back side cover 27 are connected.

  As a result, the antenna unit 11 is sandwiched between the front surface side cover 26 and the back surface side cover 27 constituting the main body unit 10 and is disposed in the main body unit 10.

  In addition, as the antenna part 11, the thing by which the elongate slot 13 was formed in the electroconductive vertically-long rectangular thin metal plate material 12 (a metal foil is also included) can be used independently.

  Further, as the antenna portion 11, the metal plate material 12 in which the slot 13 is formed may be covered with a non-conductive synthetic resin sheet 34. The thing covered with the synthetic resin sheet 34 suppresses generation | occurrence | production of the rust of the metal plate material 12. FIG.

  Further, as shown in FIG. 7, it is preferable that a vent hole 31 is formed in the front side cover 26 or the back side cover 27. In this way, when the vent hole 31 is formed, when the back surface side cover 27 is overlapped with the portion surrounded by the wall portion 28 of the front surface side cover 26 via the antenna portion 11 and connected as described above, Can be taken out from the vent hole 31 and can be easily assembled.

  FIG. 8 and FIG. 9 show another example of the main body 10 configured by combining and combining a front surface side cover 26 and a back surface side cover 27 which is a separate body.

  In this example, the back surface side cover 27 is disposed on the back surface of the front surface side cover 26 via the antenna unit 11, and the front surface side cover 26 and the back surface side cover 27 are connected by screws 32, so that the antenna unit 11 is connected to the front surface side cover. 26 and the back surface side cover 27 and disposed in the main body 10.

  Here, as the antenna unit 11, a metal plate 12 covered with a non-conductive synthetic resin sheet 34 as shown in FIG. 8 is used, and a portion that does not overlap the metal plate 12 at the end of the synthetic resin sheet 34. A hole 35 is formed in the hole. A boss 36 is formed on the back surface of the front cover 26.

  And the antenna part 11 is arrange | positioned at the back surface of the surface side cover 26, and the hole 35 is engage | inserted by the boss | hub 36. FIG. In this state, the back surface side cover 27 is disposed on the back surface of the front surface side cover 26, and the screw 32 is inserted from the hole 37 of the back surface side cover 27 and screwed into the boss 36. It is sandwiched between the side cover 27 and disposed in the main body 10.

  FIG. 10 shows still another example of the main body 10 configured by combining and combining the front surface side cover 26 and the back surface side cover 27 which is a separate body.

  In this example, a back surface side cover 27 having a pressing projection 39 protruding from the front surface side is connected to the back surface of the front surface side cover 26 via an elastic connecting portion 38. The pressing protrusion 39 protruding from the front surface side of the back surface side cover 27 is elastically brought into contact with the back surface of the front surface side cover 26 by the elastic force of the elastic connecting portion 38.

  The antenna unit 11 is interposed between the front surface side cover 26 and the rear surface side cover 27 and is pressed against the rear surface of the front surface side cover 26 by the pressing protrusions 39.

  Here, in order to interpose the antenna unit 11 between the front surface side cover 26 and the rear surface side cover 27, the rear surface side cover 27 is opened against the elastic force of the elastic connecting portion 38, and the antenna unit 11 is formed on the rear surface of the front surface side cover 26.
