[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a satellite broadcast receiving antenna mounting device for detachably mounting a satellite broadcast receiving antenna on an antenna mast.

[0002]

2. Description of the Related Art As a device for mounting a satellite broadcast receiving antenna on the top of an antenna mast, for example, there is an antenna mounting device shown in FIG. This is the antenna mast 61
The cylindrical body portion 62 fitted on the top of the ridge is set on the antenna mast 61 with the fastening bolts 65 and the nuts 66 inserted into the seat portions 64, 64 sandwiching the slit 63 at a position where a predetermined azimuth angle is formed. At the tip of a forked portion 67 protruding from the top of the portion 62, a rear face portion 69 of a housing 68 of the planar antenna is supported by a spindle 70,
70 is rotatably attached, and one end of an elevation angle adjusting plate 71 having a long hole formed in the casing rotating direction is fixed to the lower end of the rear face portion 69 of the casing 68, and the top of the cylindrical portion 62 is provided with the above-mentioned. The fixing bolt 73 inserted through the long hole is attached, and the fixing bolt 73 is screwed to the elevation angle adjusting plate 71 at a predetermined elevation angle position to set the housing 68 to the tubular portion 62.

Further, there is an antenna mounting device shown in FIG. 11, for example, for mounting a satellite broadcast receiving antenna in the middle of the antenna mast. In this case, loosen the bolt 77, adjust the parabolic reflector 78 to the elevation angle of the antenna at the receiving position, set it on the mount body 79 with the bolt 77, and then insert the mount body 79, the U-shaped bolt 80 attached to this, and the The antenna mast 82 is inserted into the space formed by the holding metal fitting 81 attached with the nuts 83 and 83, and the parabolic reflector 78 is temporarily fixed with the nuts 83 and 83 with a substantially predetermined azimuth angle. Antenna mast 8 with receiving metal fittings 84, 84 and pressing metal fitting 81
When 2 was sandwiched and temporarily attached, the elevation angle and azimuth angle of the parabolic reflecting mirror 78 were adjusted again, and the nuts 83 and 83 were set on the antenna mast 82.

[0004]

Since the antenna mounting device as shown in FIG. 10 is mounted on the top of the antenna mast 61 and the planar antenna is arranged directly above the antenna mast 61, the antenna mounting device can be mounted in the middle of the antenna mast 61 for use. Can not. Therefore, the elevation angle and azimuth angle must be adjusted at a high position.
It can be an inefficient task with poor footing.

FIG. 11 shows an antenna mast 82.
It is used by attaching it in the middle of the above, but since the holding metal fitting 81 interferes with the attachment from the side, the work is performed after removing it from the U-shaped bolt 80. For this reason, the U-shaped bolts
0 is fitted to the antenna mast 82 , the pressing metal fitting 81 is inserted into the antenna mast 82 , the nuts 83 and 83 are attached to the U-shaped bolt 80, and then the fastening is performed, which is an inefficient and complicated antenna mast attachment work. When the elevation angle becomes large regardless of whether the satellite broadcasting receiving antenna is a parabolic antenna or a planar antenna, the antenna mast 76 may come into contact with the upper part of the antenna rear surface and the elevation angle range may be limited, making it impossible to receive depending on the receiving area. . To avoid this, mount body 79
If the bulge is extended to the front, the inconvenience of increasing the size of the mast attachment device occurs.

Further, in the antennas shown in FIGS. 10 and 11, the antenna mounting position is specified by the antenna mast mounting position. Therefore, when it is desired to change the antenna mounting position with respect to the antenna mast mounting position, an antenna of a size corresponding to the antenna mounting position is required. There was a waste of manufacturing the mounting device separately.

The present invention has been made in view of the above-mentioned circumstances, and the position of the antenna with respect to the mounting position of the antenna mast can be changed even when the same antenna elevation angle is taken, and the position of the antenna mast can be changed between the top and the middle. It is an object of the present invention to provide a satellite broadcast receiving antenna mounting device that can be easily set.

[0008]

In the satellite broadcast receiving antenna mounting apparatus according to the present invention, the crank mounting portion 8 is provided on the outer wall of the mast mounting tool 6 provided with the mast mounting / dismounting knob 4, One end of the first crank 9 is attached to the upper portion of the crank attachment portion 8 by a pivot 27, and an arc hole 29 centered on the pivot is formed in the lower portion, and an elevation angle adjusting knob is formed by inserting the shaft portion into the arc hole. 11, one end of the second crank 10 is removably attached to the first and second cranks 9,
Numeral 10 has the same mounting point intervals at both ends, and the other ends thereof are pivotally attached from the vicinity of the center of the back surface portion 37 of the casing 1 of the satellite broadcast receiving antenna toward the end portion with an interval equal to the radius of the arc hole 29. At the same time, the rear surface portion 37 of the housing 1 is formed with abutting portions 44 and 45 which come into contact with a part of the upper surface side of the first crank 9 and a part of the lower surface side of the second crank 10. . With the above configuration, the antenna elevation angle can be roughly classified and adjusted by the following three methods.

With the upper surface side of the first crank 9 in contact with the contact portion 44 of the housing 1, the elevation angle adjusting knob 11
Is slid over the arc hole 29 to adjust the antenna elevation angle (FIGS. 6 and 7).

The lower surface side of the second crank 10 is the housing 1
Elevation angle adjusting knob 1 in a state of abutting against the abutting portion 45 of the
1 is slid on the arc hole 29 to adjust the elevation angle of the antenna (FIGS. 4 and 5).

The elevation angle adjusting knob 11 is slid on the arc hole 29 to adjust the antenna elevation angle without contacting the first and second cranks 9 and 10 with the contact portions 44 and 45 of the housing 1. .

The first and second cranks 9 and 10 are the housing 1
Since the parallelogram link mechanism is constituted by the crank mounting portion 8 and the crank mounting portion 8, the straight line passing through the mounting points of the cranks 9 and 10 of the housing 1 and the position where the elevation angle adjusting knob 11 is farthest from the mast mounting tool 6 (hereinafter referred to as forward limit 6) when the center of the elevation angle adjusting knob 11 and the straight line passing through the center of the pivot 27 are parallel to each other, that is, in the elevation angle setting method of FIG.
In the elevation angle setting method of Fig. 4 and in the elevation angle setting method of Fig. 4, when the elevation angle adjusting knob 11 is in the forward limit,
The maximum elevation angles obtained are the same.

Similarly, the straight line passing through the mounting points of the cranks 9 and 10 of the housing 1 and the elevation angle adjusting knob 11 when the elevation angle adjusting knob 11 is at the position closest to the mast fixture 6 (hereinafter referred to as the backward limit). 7 is parallel to the straight line passing through the center of the pivot 27, that is, the elevation angle setting method shown in FIG. 7, the elevation angle setting method shown in FIG. 5, and the elevation angle setting method shown in FIG. The minimum obtained elevation angle is the same when is in the backward limit.

In this case, the maximum elevation angle obtained by the elevation angle setting method of, remains only in the state shown in FIGS. 6 and 4, but in the elevation angle setting method, the elevation angle adjusting knob 11 is set to the forward limit. The lower surface side of the second crank 10 is the housing 1
Within a range from immediately before abutting against the abutting portion 45 of the housing 1 to immediately before abutting the upper surface side of the first crank 9 with the abutting portion 44 of the housing 1 with the elevation angle adjusting knob 11 set to the forward limit . so,
The elevation angle obtained by translating the housing 1 in parallel with the elevation angle adjustment knob 11 set to the forward limit is the maximum elevation angle. This can be said in the case of the minimum elevation angle and also in the case where the elevation angle adjusting knob 11 is set at an arbitrary position of the arc hole 29.

Therefore, even when the same elevation angle is set,
The position of the housing 1 with respect to the mast attachment 6 can be variously changed in the up-down direction and the front-back direction by the elevation angle setting method of.

[0016] Next, in the angle of elevation setting method, the first of the class
Since the link 9 is inclined along the upper side of the back surface portion 37 of the housing 1 and the top of the housing 1 is located near the top of the crank mounting portion 8, the elevation angle adjusting knob 11 is set to the forward limit, that is, the maximum elevation angle. The top of the housing 1 does not reach above the antenna mast 3. Therefore, the mast attachment 6 can be attached in the middle of the antenna mast 3. Also, the elevation angle adjustment knob 11
When is set to the backward limit, that is, the minimum elevation angle, the case with the antenna mounting device becomes the most compact compared to the other two methods.

In the elevation angle setting method, the first crank 9
The angle formed by the upper side of the back surface portion 37 of the housing 1 is an obtuse angle. Therefore, at the maximum elevation angle (FIG. 4), the top of the housing 1 reaches above the antenna mast 3. Therefore, the mast attachment 6 needs to be attached to the top of the antenna mast 3.

In the case with the antenna mounting device, as shown in FIG. 7, if the upper surface side of the first crank 9 is brought into contact with the contact portion 44 of the case 1 and the elevation angle adjusting knob 11 is set to the backward limit, It becomes the most compact, and further becomes more compact by forming a recess 38 that can accommodate a part of the first crank 9 on the upper side of the back surface portion 37 of the housing 1.

The first crank 9 includes a pair of links 31, 3
Although only the middle of 1 is integrally connected by the connecting piece portion 32,
In the second crank 10, the ends of the pair of links 33, 33 on the housing side are integrally connected by a connecting piece 34, and the seats 35, 35 are integrally projected on the inner wall of the end on the crank attachment 8 side. There is. Therefore, the crank mounting portion 8 is attached to the lower crank 10.
Since the thickness within the moving range is reduced to the distance between the pair of seat portions 35, 35, the weight is reduced.

The mast attachment 6 has one side of the divided mast guide cylinders 15 and 16 openably and closably connected by a hinge 17, and a detachable locking piece 21 is provided on the other side thereof. It can be installed and removed in the middle of the mast 3.
Since the grooves 18 and 19 into which the cap 5 can be inserted and removed are formed in the upper portions of the inner peripheral surfaces of the mast guide cylinders 15 and 16 which are divided into two parts, if the cap 5 is attached to the grooves 18 and 19, the antenna mast 3 The mast attachment 6 can be attached and detached to the top.
