Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna mounting bracket for receiving satellite broadcasting, and more particularly to an antenna mounting bracket which can move the pole position without misalignment of the adjusted antenna.

[0002]

2. Description of the Related Art An antenna for receiving a satellite broadcast that has been used conventionally is required to receive a radio wave of a required satellite.
Fix the antenna to a pole installed so that it is almost vertical to the ground, first make a coarse adjustment in the elevation direction of the antenna, then rotate around the pole to make a coarse adjustment in the azimuth direction and receive. It is common practice to repeat the fine adjustment of the azimuth angle and the fine adjustment of the elevation angle several times while observing the level and then perform a series of procedures for fixing the antenna. However, if you want to move the installation location after making such complicated adjustments, for example, adjust the antenna attached to the window frame before the window, and move it to a place that does not interfere with the actual installation, It is necessary to readjust the adjustment again.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and is adjusted even if the position of the pole is moved after performing the rough adjustment and the fine adjustment in the elevation angle direction and the azimuth angle direction of the antenna. It is intended to provide an antenna mounting bracket that does not shift.

[0004]

In order to solve the above-mentioned problems, the present invention has a rotating shaft rotatably arranged on a mast, the rotating shaft being inserted and attached to one end, and the antenna being attached to the other end. A connecting arm that pivotally supports the pole, and a first bevel gear provided on the upper part of the rotating shaft so as to rotate integrally with the rotating shaft,
A second bevel gear that is provided so as to mesh with the first bevel gear on a connecting cylinder that is inserted on the rotating shaft, and a third bevel gear that meshes with the second bevel gear and is inserted on the rotating shaft. A bevel gear and the third
The first spur gear that rotates integrally with the bevel gear, the second spur gear that is attached to the lower portion of the antenna mounting pole at a position corresponding to the first spur gear, and the power of the first spur gear are And a transmission means for transmitting to the spur gear.

[0005]

With the above construction, in the antenna mounting bracket according to the present invention, the rotating shaft rotatably disposed on the mast is inserted into one end of the connecting arm, and the antenna is attached to the other end. After adjusting the elevation angle and azimuth angle of the antenna by pivotally supporting the antenna pole, and then rotating the connecting arm by a required angle, the antenna mounting pole is passed through a bevel gear and a spur gear provided on the rotary shaft. Is transmitted to the spur gear attached to the antenna, and the antenna mounting pole rotates in the opposite direction by an amount corresponding to the rotation angle of the connection arm, whereby the direction in which the antenna faces can be kept constant.

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 is a top view and a side view of an essential part of an embodiment of the present invention, and FIG. 2 is a side view of an essential part of another embodiment of the present invention. In the drawing, reference numeral 1 is a connection arm, and a rotating shaft 2 rotatably disposed on a mast 12 installed at a window or the like is inserted at one end thereof, and an antenna mounting pole 3 having an antenna 11 at the other end is pivotally supported Has been done. A first bevel gear 4 is provided above the rotary shaft 2,
A second bevel gear 5 is provided so as to mesh with the first bevel gear 4. The second bevel gear 5 is axially supported by a connecting cylinder 6 inserted into the rotary shaft 2. Reference numeral 7 denotes a third bevel gear, which is provided so as to mesh with the second bevel gear and is inserted into the rotary shaft 2. Reference numeral 8 is a first spur gear that rotates integrally with the third bevel gear 7. Reference numeral 10 denotes a second spur gear, which is inserted in a position corresponding to the first spur gear 8 below the antenna mounting pole 3 and further supplies the power of the first spur gear 8 to the second spur gear. To transmit to 10, transmission means 9 consisting of a belt or a chain is provided.
Explaining an operation example, at the same time when the connecting arm 1 is rotated, the rotating shaft 2 and the first bevel gear 4 provided on the rotating shaft 2 are rotated, and the power of the first bevel gear 4 is transferred to the second bevel gear 5. Power is transmitted by this second bevel gear 5 so that the third bevel gear 7 rotates in the opposite direction to the first bevel gear,
The power of the third bevel gear 7 is passed through the first spur gear 8 that rotates integrally, and by the transmission means 9 such as a belt or a chain, the second spur gear 1 provided on the antenna mounting pole 3.
0, and the antenna mounting pole 3 rotates integrally with the second spur gear 10.

Further, in the above, in order to transmit the rotation in the direction opposite to the rotation direction of the rotating shaft 2 to the antenna mounting pole 3, a first bevel gear 13 is provided on the upper portion of the rotating shaft 2, and the first bevel gear is provided. 13 is provided with a second bevel gear 14 that meshes with the second bevel gear 14, and the second bevel gear 14 is inserted and attached to one end of the rotary shaft 2
Rotatably attached to the connecting tube 15 inserted in the
A bevel gear 17 is inserted and attached, and a connecting shaft 16 rotatably attached to a connecting cylinder 19 having an end portion inserted in the antenna mounting pole 3 is provided so as to mesh with the third bevel gear 17. Even if the fourth bevel gear 18 is provided on the antenna mounting pole 3, the same effect can be expected. In the above,
After the connecting arm 1 and the rotary shaft 2 are rotated to a required angle, a fixing means, for example, a screw stop, is fixed to the mast 12 to prevent the rotary shaft 2 from moving. It is provided.

[0008]

As described above, in the antenna mounting bracket according to the present invention, the rotating shaft rotatably disposed on the mast is inserted into one end of the connecting arm, and the antenna is attached to the other end. After the mounting pole is pivotally supported and the elevation angle and azimuth angle of the antenna are adjusted, when the connection arm is rotated by a required angle, the bevel gear and the spur gear provided on the rotation shaft are used to attach the antenna. The direction in which the antenna faces can be kept constant by being transmitted to the spur gear mounted on the pole and rotating the antenna mounting pole in the opposite direction by the amount corresponding to the rotation angle of the connecting arm.
