In exterting a force, e.g. counterclockwise, to a fitting frame 322, the screw 56 is turned clockwise by taking a pin 55 as a fulcrum. The horizontal arm 57 screwed by the screw 56 is turned incorporatedly together with the screw 56 in this case, causing the parabola antenna also to turn clockwise. Thereafter, minute adjustment is executed. That is, the horizontal arm 57 is turned around the pin 55 by turning a horizontal minute adjusting screw 65, causing the parabola antenna to be turned.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention is...72? The present invention relates to an angle adjustment device suitable for adjusting the elevation angle and horizontal rotation angle of an antenna.

[Technical background of the invention]

FIG. 1 is a side view showing an example of a conventional Noyaradera antenna device. In the figure, 11 is a paragela antenna. 12 is a reinforcing member for reinforcing the strength of this parabolic antenna 11.

This reinforcing member 12 is joined so as to cover the back surface of the i+rapora antenna 11. 13 is para antenna 11
This is a support for attaching the

- The mother mullet antenna 11 is attached to the support 1 via the holding mechanism 14.
It is attached to 3. This holding mechanism 14 has holding members 15, 16 arranged vertically (in the vertical direction) and holding members 17 arranged diagonally. A parallax antenna is attached to one end of the holding member 15' so as to be rotatable within a vertical plane. The other end Vi mounting bracket 18 of this holding member 15
It is fixed to the pillar 13 via. The holding member 16 is rotatably supported by a mounting bracket 19 fixed to the support column 13. In this case, the holding member 16 has a plurality of mounting holes 20.
is formed, and is pivotally supported by the mounting bracket 19 through any one of the plurality of mounting holes 20. This holding member 16 is connected to the parallax antenna 11 by a fine adjustment screw 21.

According to the above configuration, by appropriately selecting the mounting hole 20'fc for pivotally supporting the holding member 16 on the mounting bracket 19,
Elevation angle of paragela antenna 1 (tilt angle in vertical plane)
That is, the inclination angle in the direction of the arrow (X!14+X4) shown in the figure can be adjusted as appropriate. That is, the holding member 1
6 and 9? In other words, if the parallel antenna 11GIl11 is projected in the direction of the arrow X1 shown in the figure, the parallel antenna 11 will be tilted in the direction of the arrow X3 shown in the figure. Conversely, if the holding member 14 is moved in the direction of the arrow x2 shown in the figure, the antenna 11
continues in the direction of arrow X4 in the figure. After the elevation angle has been roughly set in this manner, the elevation angle is finely adjusted by operating the fine A adjustment screw 16 and the screw is fed, so that the desired elevation angle of the PJT can be obtained.

FIG. 2 is a side view showing another n of the conventional 79 lapora antenna device. Note that the same parts in FIG. 2 as in FIG. 1 are given the same reference numerals. In this example, the holding mechanism for attaching the parabolic antenna 11 to the support column 13 is slightly different from the holding mechanism LΔ in the previous example. That is, the antenna 11 is parallel to the holding member 26 on the upper side in the figure. Regarding the relationship with the pillar 13, the parabolic antenna 11 is fixed to a holding member 26, and the holding member 26 is rotatable to the pillar 13 via a mounting bracket 27. The holding member 28 is inclined in the opposite direction to the previous holding member 17. Holding member 29. Mounting bracket 30. Regarding the fine adjustment screws 31 and 16, respectively, the previous holding member 16.
Mounting bracket 19. It has approximately the same configuration as the fine adjustment hook screw 21.

According to the above configuration, Nokura? The antenna 11 can obtain a predetermined elevation angle by rotating the mounting bracket 27. A state in which the parabolic antenna 11 is tilted in the direction of the illustrated arrow xzy-J is shown by a two-dot chain line.

[Problems with background technology]

By the way, when configuring a parallax antenna device, it is necessary to pay attention to the following points.

(1) The strength of the parabolic antenna 11 can be made sufficiently large.

(2) The holding mechanism opening or lever can hold the parabolic antenna 11 completely stably. That is, even if the 7Q annoying antenna 1 has a diameter of 1 m, it has only about 20 directivity angles. On the other hand, for example, parabolic antenna 1 generally has a large diameter, such as 1 m in diameter as mentioned above,
Moreover, since it forms a hyperboloid, a large wind pressure is applied to the parabolic antenna 11 during use. Therefore, the holding mechanism 14 or Mu! If the strength is weak, the position of the parallax antenna 11 will shift, making it impossible to receive radio waves well.

(3) The parabolic antenna 11 must have an elevation angle adjustment function and a rotation angle adjustment function. Note that the rotation angle is the tilt angle in the horizontal direction, and the angle in the horizontal direction.
In the example shown in FIGS. 1 and 2 above, this is the rotation angle around the support 13.

Considering the above-mentioned three points with respect to the previous conventional devices, first of all, regarding point (1), all conventional devices are designed by fixing the reinforcing member 12 to the back of the parabolic antenna 11 with many screws. It has a reinforcing effect. However, although such a configuration is effective for a standard type parabolic antenna in which the hyperboloid axis coincides with the center, in an offset type parabolic antenna that can be expected to have the same characteristics such as efficiency, the reinforcing member 12 and the parabolic antenna are Since the joint surface with 11 is not a simple curved surface, reinforcement is difficult. Therefore, in such an offset type parabolic antenna, it is necessary to strengthen the antenna itself.

In other words, a parabolic antenna is manufactured by forming a main body made of so-called FRP that has a radio wave receiving surface and a reinforcing part that reinforces its strength, and forming a metal surface on the radio wave receiving surface of this main body. . However, this method has problems in that the material for the antenna is expensive and the manufacturing process is difficult, thus increasing manufacturing costs.

Regarding point (2), in order to realize this, the holding mechanism L
This has the disadvantage that the holding mechanism 14, 25 becomes large and heavy. The reason for this is that the holding mechanism in, zs must support not only the parabolic antenna 11 but also the parabolic antenna 11 plus the reinforcing member 12. In addition, the Noyara antenna 11 has a rotation fulcrum on its upper end side, and the elevation angle is adjusted around the rotation fulcrum. As shown, the distance between the portion from the center to the lower end of the parabolic antenna 11 and the support column 13 becomes large. This means that the strength of the holding member (16, 29, etc.) must be strengthened without any modification, and the holding member 16 becomes larger and heavier when stacked.

Regarding point (3), the elevation angle adjustment is made by selecting the mounting hole of the holding member 16 or 29. However, this is only a coarse adjustment, and fine adjustment is performed using the fine adjustment screw 21 or 31. In this case, the elevation angle adjustment range is 70°~
Since it is necessary to set a relatively large angle of 800, the coarse adjustment adjustment angle is divided into about 150 steps and 3 steps.
The angle between them is adjusted by a fine adjustment screw 21 or 31. However, in the case of the conventional device, the rotational fulcrum of the parallax antenna 1 is set at its upper end, so the portion of the parallax antenna 11 where the fine adjustment screw 21 or 31 is provided (parallel antenna 11), the amount of deviation per coarse adjustment step is large. This means that the feed amount of the fine adjustment screw 21 or 3I must be increased, which means that the dimensions of the fine adjustment screw 21 or 31 must be increased accordingly, and as a result, its strength must be increased. Thick screws must be used to maintain the Therefore, the operability of fine adjustment becomes worse. Still fine adjustment screw 21
Alternatively, 31 is not fixed, but moves as the parabolic antenna 11 rotates. Therefore, it is not possible to perform fine adjustment operations at the same position all the time, resulting in poor operability.

Furthermore, conventional devices do not have any function for adjusting the rotation angle in the horizontal direction.

[Purpose of the invention]

The present invention has been made to address the above-mentioned circumstances, and specifically aims to provide an angle adjustment device that enables not only fine adjustment of the elevation angle, but also coarse and fine adjustment of the rotation angle in the horizontal direction. .

[Summary of the invention]

This invention supports an angle-adjusted object whose elevation angle and horizontal rotation angle are to be adjusted.When adjusting a 1fp angle, the object is rotatably supported in the elevation angle adjustment direction, and when the rotation angle is adjusted, it is rotated in the rotation angle adjustment direction. a support means for freely supporting the object; a fixing member fixed at a predetermined position; an elevation adjustment screw attached to the fixing member so as to be rotatable in the rotation angle adjustment direction; a horizontal member that is moved in its axial direction by rotation of the elevation adjustment screw; a connecting member that connects the horizontal member and the fixed member; and a connecting member that connects the connecting member and the fixed member. a first coupling means that connects the two in a loose manner during angle adjustment and rough adjustment of the rotation angle, and fixedly connects them during fine adjustment of the rotation angle; and a first coupling means that couples the connecting portion and the horizontal member. a second coupling means for loosely coupling the two during coarse adjustment and fine adjustment of the rotation angle when adjusting the elevation angle; and a rotation angle adjustment screw that applies a force to rotate the elevation adjustment screw using the rotation fulcrum of the elevation angle adjustment screw as a fulcrum. The rough adjustment of the rotation angle is performed by applying force to the object to be adjusted in the rotation angle adjustment direction.

[Embodiment of the Invention j Hereinafter, an embodiment of the present invention will be described in detail with reference to all the drawings. FIG. 3 is a perspective view of a parabolic antenna device according to an embodiment, seen from the front side of the parabolic antenna, and FIG. 4 is a perspective view seen from the back side. FIG. 5 is a front view of the parabolic antenna device, and FIG. 6 is a side view. In FIG. 3 and □FIG. 4, 31 is a parabolic antenna, and 32 is a holding member. 33 is a primary feed. The holding member 32 has an abbreviated shape and is arranged so as to straddle the back mi of the parabolic antenna 31, and at both ends)! It is fixed to the periphery of the laboratory antenna 31. In addition, the holding member 32
is shown in Figure 5 fm<, -7 uka? A pair of antennas are arranged symmetrically on both sides of the vertical central axis t of the antenna 3 with a predetermined distance therebetween. Both ends of the holding portion 32 are fixed to a flat portion 31 formed around the parabolic antenna 31 with screws 34. Primary feed 3
3 is an arm 35 screwed to the lower end of the holding member 32;
is attached to.

As shown in FIGS. 4 and 6, the holding member 32 is actually attached to a holding frame 321 that is fixed to the parabolic antenna 31 and a frame 3 that is fixed to the holding frame 321 with screws.
Consists of 22. Reinforcing beams 36 are screwed at three locations, at both ends and at the center, between a pair of fixed frames 321 arranged symmetrically.

One wing IA and the other wing 2 of the p-shaped mounting frame 322
A plurality of mounting holes are formed in each of A as shown in FIG. Now, attach the mounting hole group formed on one wing IA to the bent part in order from the farthest mounting hole toward the bent part.

. In addition, the straight line tn connecting mounting holes na and nb and the mounting hole (
The angle Δα formed with the straight line Ctn+1) connecting n+1)a and (n+1)b is always set to be substantially equal.

Note that the holding frame 321 and the Noyara Dera antenna 31 are fixed, for example, as shown in FIG. Ru.

The Kuno4 antenna 31 with the holding member 32 attached in this manner is attached to the support column 39 via, for example, attachment fittings 37 and 38, as shown in FIGS. 4 and 6. In addition,
The mounting bracket 38 is not shown in FIG. If you install this, the mounting hole In.

2 a s 3 a m -” s 1 b * 2
This is done by fixing the mounting frame 322 to the mounting bracket 37.38 with, for example, screws 40.41 via the mounting hole 1b. Fixing to the mounting bracket 38 is performed through the mounting holes 1a that form a pair with the mounting holes 1b.In this way, the mounting frame 322 is always screwed by selecting the mounting holes that form a pair. In this case, the adjustment range of the elevation angle of the parabolic antenna 31 is the angle α formed by the straight line connecting the mounting holes at both ends, as shown in FIG. The adjustment angle for one coarse adjustment step is the aforementioned Δα, which is determined by the number of mounting holes.

When actually attaching the parabolic antenna 31 to the support column 39, first select a pair of attachment holes suitable for obtaining the desired angle of elevation. This can be easily determined by calculation in advance. Thereafter, the mounting frame 322 is temporarily fixed to the mounting brackets 37 and 38 with screws 40 and 41 using the selected pair of mounting holes. Thereafter, for example, by operating a fine adjustment mechanism provided on the mounting bracket 37, the elevation angle is set to a desired value. This fine adjustment mechanism will be described later, but fine adjustment of the angle of elevation is performed by moving the parallax antenna 31 in its front and rear directions (in the direction of arrow X1←Xz in the figure). In this case, will you come? The antenna 31 rotates about the screw 41 as a fulcrum.

Once the desired elevation angle is obtained, the screws 40, 41 are fixed, thereby completing the installation of the parabolic antenna 31 and the elevation angle adjustment. Note that adjustment of the horizontal rotation angle will be described later.

According to the above configuration, the holding member 32 is attached to the parallax antenna 3.
1 and attaching it to the pillar 39, it also serves as reinforcement for the parabolic antenna 31, so the parabolic antenna 31
There is no need to process it to increase its strength. Therefore, it is not a fool that can cope with the reinforcement of any type of parallax antenna 31.
can be manufactured easily and inexpensively.

In addition, in order to obtain the desired elevation angle, instead of providing a fixed rotation fulcrum and rotating the parabolic antenna 31 around this fulcrum as in the conventional case, the parabolic antenna 31 is provided on the L-shaped mounting frame 322.

Since the structure is such that the distance between the parabolic antenna 31 and the support column 39, for example, the distance shown in FIG. 7, can be set to a small value, no matter what angle of elevation is obtained, can. In addition to this, as mentioned above,
Since the parabolic antenna 31 does not require any processing to increase its strength, the parabolic antenna 31 is 7.
＼ type, lightweight. Furthermore, since the distance L1 between the pair of mounting holes can be increased, the strength of the holding member 320 is reinforced, and the holding member 32 can be made smaller and lighter.

In addition, as described above, instead of providing a fixed rotation fulcrum, mounting holes 1a+'2 formed in the L-shaped holding member 32 are used.
Since the elevation angle is determined by selecting ``aa3as'', 1lbr2b13b, . If this is to be achieved using a fine adjustment screw, the amount of feed can be reduced.This allows the use of short and thin screws as the fine adjustment screw, improving the operability of the fine adjustment. Further, according to the above-mentioned Hiko configuration, the fine adjustment mechanism can be fixed, so fine adjustment can always be made at the same position.

Another advantage is that the parallax antenna 31 can be easily attached to the support post 39 by simply selecting a pair of mounting holes and screwing the mounting frame 322 to the mounting brackets 3.7 and 38 using the selected mounting holes. have

In addition, by appropriately setting the position of the mounting hole, the adjustment range α can be made to approximately match the bending angle of the mounting frame 322, so by increasing this bending angle, the elevation angle can be adjusted over a very wide range. can be done.

In addition, the mounting holes 1 & l 2 a + s are provided in the mounting frame 322.

The workability of the installation work can be improved by displaying the elevation angle when the antenna 3 is installed on the support post 32 in the vicinity of the antenna 32.

Furthermore, by setting the relationship between Δα and Ll so as to allow slight variations, the additional issue holes can be shared and the number of mounting holes can be reduced.

Further, the holding member 32 does not need to be composed of two parts, the fixed frame 321 and the attachment frame 321, and may be formed of, for example, one part.

The attachment mechanisms 37 and 38, which are the features of this invention, will now be explained. First, the attachment mechanism 38 located on the lower side will be explained using FIG. 9.

Reference numerals 45 and 46 denote fixing fittings, which have curved parts 451 and 461 in the center that fit into the support column 39. These fixing fittings 45.
46 are arranged opposite to each other so as to sandwich the support column 39 at curved portions 451 and 461.

Through holes 452 and 462 are formed at corresponding positions on both ends. A horizontal arm 47 is installed on one wing side I of the pair of mounting frames 322. Its installation position corresponds to the selected attachment hole na of this one wing side IA, and it is screwed through this attachment hole na. At the horizontal arm 47, the fixing fittings 45, 46. through hole 4

46 is fixed to the support column 39.

Next, the upper mounting mechanism 37 will be explained.

FIG. 10 is a plan view of the mounting mechanism 37, FIG. 11 is a side view of the mounting mechanism 37 shown in FIG. FIG. 13 is a perspective view looking diagonally upward in the direction of arrow x7 in the figure. In the figure, reference numeral 51.52 denotes a fixing metal fitting, which has a curved portion 511.521f in the center.

The curved portions 511 and 521 are arranged opposite to each other so as to fit into the column 39, and are fastened to the column 39 by screws 53 at both ends. Fixing metal fittings 51
．． 52 is fixed to the support column 39, as shown in the fourth section above.
As shown in the figure.

Note that the fixing fittings 52 are shown in FIGS. 11, 12, and 13.
is not shown.

At the center of the curved portion 511 of the fixing fitting 51, a coarse moving fitting 54 is supported by a pin 55 so as to be rotatable in the horizontal direction. An elevation adjustment screw 56 is rotatably attached to the coarse adjustment fitting 54. A horizontal arm 57 is engaged with the elevation adjustment screw 56 and moves in its axial direction as the elevation adjustment screw 56 rotates. A nut 58 is fixed to the horizontal arm 57 and is screwed onto the elevation adjustment screw 56 to move the horizontal arm 57 as the elevation adjustment screw 56 rotates.

A pair of connecting members 59 between the horizontal arm 57 and the fixture 51

0 is connected to the horizontal arm 57 and the fixture 51 via bolts 61, 62, 63°64. In this case, the bolts 51.62° and 63.64 are screwed into the horizontal arm 57 and the fixing fitting 51 through long holes s91.6oz, s92, and 6o2 formed in the connecting member 59.60. By the action of the long holes 591, 592, 601, 602, the connecting member 59, 60 and the horizontal arm 57 or the fixing metal fitting 51
The relative positions of can be changed slightly. Connecting member 6
The side end of the horizontal arm 57 of 0 is bent downward, and this bent part 603 has a horizontal profile. Several A setting screws 65 are rotatably screwed. This horizontal fine adjustment screw 65 is
It is screwed into a nut 66 fixed to 7. By rotating the horizontal fine adjustment screw 65, it is possible to mainly move the portion of the horizontal arm 57 corresponding to the connecting member 60 along the length direction of the connecting member 60. Normally, the elevation adjusting screw 56 and the connecting member 59.60 are approximately parallel to each other, and the connecting member 59,60 is disposed in line symmetry with respect to the elevation adjusting screw 56.

The horizontal member 57 (like the fixing metal fitting 51) is slightly elongated, and the other wing side 2A of the pair of mounting frames 322 is fixed to both ends thereof by the screws 40. Of course, in this case as well, the screw 67 is inserted into the selected mounting hole nb of the other wing side 2A.

In the case of Del Toro 3,64F fixed, e Cito 51.62

The angle of elevation can be finely adjusted.

FIG. 15 is a plan view for explaining rough adjustment of the rotation angle in the horizontal direction. in this case? Loosen seats 61-64.

Also, loosen the screw 48 shown in FIG.
6 can rotate around the axis of the support column 39. In this state, if a force is applied to the mounting frame 322, for example, in a clockwise direction in FIG. 15, the elevation adjustment screw 56 rotates clockwise about the pin 55 as a fulcrum. At this time, the horizontal arm 57, which is coupled to the elevation adjustment screw 56 by threading, also rotates integrally with the elevation adjustment screw 56. Therefore, the parabolic antenna 31 also rotates clockwise. At this time, the mounting brackets 51 and 52 do not rotate because they are fixed to the support column 39. Therefore, the relative positions of the horizontal arm 52 and the fixture 51 are on the right side in the figure, and at this time the lower fixtures 47 and 46 rotate. Also, the relative position of the horizontal arm 57 and the connecting member 60, for example, the illustrated interval LsFi
Since both are connected by the horizontal fine adjustment screw 65, there is no change. What if you can get the approximate rotation angle in this way? Tighten the bolts 63 and 64, but leave the bolts 61 and 62 loose.

After this, the horizontal rotation angle will be finely adjusted.
This is shown in FIG. That is, the horizontal fine adjustment screw 65
By rotating the horizontal arm 51 and the connecting member 6
0 changes, the horizontal arm 57 rotates clockwise or counterclockwise around the pin 55,
Parabolic antenna 31 rotates. For example, when the horizontal fine adjustment screw 65 is operated to narrow the distance, the distance becomes wider and the distance becomes narrower.

Incidentally, the adjustment of the rotation angle is realized by rotating the horizontal arm 57 as described above, regardless of whether it is a fine adjustment or a coarse adjustment. In this case, the column 39 and the horizontal arm 57
Although it would be convenient if the center-to-center distance between the horizontal arm 57 and the
Since the pin 55 is provided in the same direction, this change can be minimized. In order to completely eliminate this change, care should be taken to align the pivot point with the center of the support column 39.

According to the above configuration, not only fine adjustment of the elevation angle but also fine adjustment and rough adjustment of the rotation angle in the horizontal direction can be performed.

Furthermore, since this can be achieved using a small number of parts and small parts, it is possible to downsize the apparatus. The parabolic antenna 3 is not fixed with fine-adjustment screws like in the past, but is fixed with special fixing screws, so it can demonstrate strong fixing ability. Also,
Since each part has a simple shape, it can be made of a material that matches the strength of the bundle, and can be assembled with inexpensive and lightweight parts. Since fine adjustment and coarse adjustment can be performed independently, operability is improved, and since the amount of change in fine adjustment can be reduced, accurate positioning is possible.

Note that it goes without saying that only one connecting member 60. may be used as the connecting member. Of course, there are various other ways of connecting the fixing fitting 5 of the elevation adjustment screw 56.

Further, the means for freely connecting the connecting members 59 and 60 to the horizontal arm 57 and the fixing metal fittings 51 are bolts 61 to 64 and long holes 591, 592, and 601°6.
It may have a configuration other than the relationship with 02. Also,
Of course, there are various other shapes of the fixing fittings 51 and 52 and various ways of fixing them to the support column 39.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide an angle adjustment device that allows not only fine adjustment of the elevation angle, but also coarse adjustment and fine adjustment of the rotation angle in the horizontal direction.
