Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting tool for mounting an antenna mounting tool for mounting a parabolic antenna or a planar antenna on a concrete handrail or the like.

[0002]

[Prior art]

 As a conventional antenna mounting tool, there is one as shown in FIG. 6, which supports a straddling member 101 that straddles the upper part of a concrete handrail of a veranda and the mast 102 on one side of the straddling member 101.

[0003]

[Problems to be solved by the device]

 Since the anchor bolts could not be attached to the conventional antenna fixtures, there was a danger of scattering due to loosening bolts in places where strong winds were expected, which was a problem for use. Further, in the conventional antenna mounting tool, the part for holding the concrete handrail was a flat plate, so that it could only be mounted on a flat part without a protrusion.

Further, in the conventional antenna fixture, since the part that holds the concrete handrail is in contact with the entire flat plate, it is not always possible to apply uniform pressure, and the concrete handrail is clamped in an unstable state, There was a risk that it could easily come off the handrail due to external force.

[0005]

[Means for Solving Problems]

 Therefore, in consideration of the above circumstances, the present invention enables the attachment of anchor bolts so that the bolts can be used even in places where strong winds are expected, and can also be attached to concrete handrails having protrusions, and the like. In order to support it evenly by pressing it uniformly, a guide square tube with a bottom is horizontally fixed to the lower end of the mast which is vertically erected, and an inverted L-shaped support is installed in the middle of the mast. The bottom end of the guide square tube is fixed so that the lower end faces the guide square tube, and the head is brought into contact with the outside of the bottom of the guide square tube. The slider is fitted in the guide square tube so that it can slide, and the screw plate fixed to the slider outer end is screwed onto the shaft of the fixing bolt. Fix the bowl-shaped presser foot of 1 And an antenna fixture formed by fixing a second bowl-like retainer having an outer peripheral flange of the annular facing the first cup-shaped retainer to the support bottom.

Furthermore, anchor bolt mounting holes may be formed in the outer peripheral flanges of the first and second bowl-shaped pressers.

[0007]

[Action]

 A concrete handrail or the like is sandwiched between the first and second bowl-shaped pressers, the fixed bolt is rotated, and the slider is advanced and retracted to thereby sandwich the antenna fixture to the concrete handrail. Furthermore, since anchor bolt mounting holes are formed in the first and second bowl-shaped pressers, the anchor bolts can be attached, and the pressers have a bowl-shaped body having an annular outer peripheral flange. Therefore, it is possible to attach it to a portion having a protrusion, and further, since the pressing tool has an annular outer peripheral flange, the concrete handrail can be evenly held and fully held.

[0008]

【Example】

 The present invention will be described in detail below based on a specific embodiment shown in the accompanying drawings. As shown in FIG. 1, the antenna mounting device of the present invention has a bottomed rectangular guide tube 2 horizontally fixed to the lower end of a mast 1 which is vertically erected, and an inverted L-shape is provided in the middle of the mast 1. The support body 3 is fixed so that its lower end faces the guide rectangular tube 2 so that it can straddle both sides of a concrete handrail that is vertically erected. A flat antenna or a parabolic antenna is attached to the upper end of the mast 1 via an angle adjusting fitting.

A head 5 is brought into contact with the outer side of the bottom portion 4 of the guide square cylinder 2, and a fixing bolt 6 having a shaft portion accommodated in the guide square cylinder 2 is provided on the guide square cylinder 2 so as to be rotatable and non-movable. A rectangular tube-shaped slider 7 is slidably provided in the guide rectangular tube 2, and a first bowl-shaped pressing member 8 is fixed to the inner end of the slider 7. Further, a second bowl-shaped pressing tool 9 is provided at the lower end of the support body 3 so as to face the first bowl-shaped pressing tool 8.

As shown in FIG. 2, the first bowl-shaped presser 8 is a bowl-shaped body 12 that is fixed to the inner end of the slider 7 and has an annular outer peripheral flange 11. A mounting hole 13 is formed, a cushion material 14 is attached to the front surface of the bowl-shaped body 12, an opening 16 communicating with a recess 15 of the bowl-shaped body 12 is formed in the center of the cushion material 14, and the cushion material 14 is also formed. Anchor bolt mounting holes 17 are similarly formed in the material 14 at positions facing the anchor bolt mounting holes 13. The second bowl-shaped pressing member 9 also forms a bowl-shaped body just like the first bowl-shaped pressing member 8, and the cushioning material 14 is attached and the anchor bolt mounting holes 13 and 17 are formed.

As shown in FIG. 3, the fixing bolt 6 inserted into the bottom portion 4 at the outer end of the guide square tube 2 is fitted with the washer 22 on the outside of the bottom portion 4 of the shaft portion 21 housed in the guide square tube 2. Then, the pin 23 is driven into the shaft portion 21 of the fixing bolt 6 through the hole 26 formed in the lower surface of the guide square cylinder 2 so that the fixing bolt 6 can rotate but cannot move forward and backward. A screw plate 25 having a nut 24 welded thereto is fixed to the outer end of the slider 7, and the shaft portion 21 is screwed into the nut 24. Therefore, when the head portion 5 of the fixing bolt 6 is turned, the slider 7 advances and retreats in the guide square cylinder 2, and the first bowl-shaped presser tool 8 narrows its interval with respect to the second bowl-shaped presser tool 9. Spread it out.

FIG. 4 shows a usage example of this antenna fixture. Straddle the upper part of the concrete handrail 31 and position the concrete handrail 31 between the first bowl-shaped presser tool 8 and the second bowl-shaped presser tool 9, rotate the fixing bolt 6 and advance the slider 7. Then, the antenna mounting tool is clamped between the concrete handrails 31 by the first bowl-shaped pressing tool 8 and the second bowl-shaped pressing tool 9. Attach the parabolic reflector antenna 32 to the top of the mast 1 via the fixture 33.

Since the cushion material 14 is attached to the entire surfaces of the first bowl-shaped pressing tool 8 and the second bowl-shaped pressing tool 9, the antenna mounting tool can be sufficiently supported with some elasticity. Further, since the first bowl-shaped pressing tool 8 and the second bowl-shaped pressing tool 9 are bowl-shaped bodies 12 having an annular outer peripheral flange 11, they can be attached to a portion having a protrusion. .

Further, since the first bowl-shaped pressing member 8 and the second bowl-shaped pressing member 9 have the annular outer peripheral flange 11, the force for pressing the both bowl-shaped bottoms is the whole of the concrete handrail 31. Can be clamped and can be fully retained. In places where strong winds are expected, as shown in FIG. 5, the anchor bolt 41 is driven into the concrete handrail 31 and inserted into the anchor bolt mounting holes 13 and 17 of the first bowl-shaped holding metal fitting 8. Install by screwing with the nut 42. In this way, there is no risk of scattering even in places where strong winds are expected, and it can be used.
