Next, the invention of the third aspect of the present application is the antenna support device of the first aspect or the second aspect,
The support is

The notch has a height dimension from the other end surface of the support to the second intermediate position that is greater than the predetermined length in a range where the male thread portion of the bolt body is formed. The dimension in the width direction perpendicular to the direction is larger than the outer diameter of the male thread portion of the bolt body,
Furthermore, a guide portion is formed on the inner wall of the communication hole to form a step with the same dimension as the width direction of the notch,
The guide portion is inclined so that the dimension in the height direction from the other end surface of the support to the step is sequentially increased from the slide hole side to the through hole side. And

According to the antenna support device of the first aspect of the present application, the support constituting the support provided on the back surface of the antenna device has a cross-section formed in a substantially T shape by the slide hole, the through hole, and the communication hole. Support holes are formed.

In addition, the base of the antenna fixture is provided with a pair of abutting pieces capable of sandwiching the support, and the bolts are inserted into the support holes through the bolts in a state of sandwiching the support. An insertion hole for penetrating the body is provided, and a female screw portion is formed in at least one of the insertion holes.

The bolt body used for connecting the support tool and the antenna mounting tool has a male screw portion that can be screwed into the female screw portion at the tip portion, and the diameter of the shaft portion that is provided continuously to the male screw portion. A half-screw type bolt configured to have a smaller diameter than the diameter of the male screw portion is used.

Further, the inner diameter of the through hole in the support hole is slightly larger than the outer diameter of the male screw portion of the bolt body, and the gap formed inside the slide hole and the communication hole in the support hole is formed as follows. Yes.

That is, the gap formed inside the slide hole and the communication hole is slightly larger than the outer diameter of the male screw portion of the bolt body from the one end surface of the support body to the first intermediate position. To the other end surface of the support body is the same as or smaller than the outer diameter of the male threaded portion of the bolt body and slightly larger than the outer diameter of the shaft portion.

Therefore, the assembly of the support and the antenna mounting member is a state in which the axes of the through holes and the through holes are substantially aligned so that the through holes provided in the respective contact pieces face each other with the through hole of the support interposed therebetween. Thus, the bolt body may be inserted from one insertion hole through the through hole to the other insertion hole.

At this time, at least the insertion hole on the side where the male screw portion of the bolt body is inserted last is arranged with an insertion hole in which the female screw portion is formed, and the male screw portion of the bolt body is arranged in the female screw portion. Screw the screw part.

As a result, according to the antenna support device of the present invention, when the support tool and the antenna mounting member are assembled, the antenna device provided with the support tool becomes an antenna mounting tool (and thus an antenna device mounting target). It is possible to prevent tilting.

And if a bolt body is clamp | tightened in this state, a support tool (and extension antenna apparatus) can be firmly fixed to an attachment target object.
In this state, if the bolt body is loosened, the bolt body can be slid from the through hole in the support hole to the slide hole along the direction of formation of the slide hole. In addition, the orientation of the antenna device can be adjusted at an arbitrary position.

Therefore, according to the present invention, the adjustable range of the antenna direction can be expanded while reducing the inclination of the antenna device that occurs at the time of installation, as compared with the above-described conventional device.
By the way, for example, in receiving a terrestrial digital broadcast signal, what is important when installing an antenna device is not only adjusting the reception level (C / N) of the broadcast signal to the maximum, but also the signal of the received signal. It is required to check the quality.

Signal quality includes BER (Bit Error Rate), MER (Modulation Error Ratio), and the like.
In other words, depending on the environmental conditions of the propagation path of the radio wave, radio waves with poor signal quality may arrive even if the reception level is high. This is because the antenna device is not necessarily directed in the correct direction (electrical azimuth angle).

Therefore, in the direction adjustment of the antenna device, even if the antenna device is pointed in a physically correct direction, depending on the signal quality of the broadcast signal coming from that direction, further direction adjustment may be performed in order to find the electrically correct direction. Considering that a situation that requires operation occurs, it is desirable that the direction adjustment angle of the antenna support device can cover as wide a range as possible.

Therefore, more preferably, the antenna support device of the present invention may be configured as in the second aspect.
That is, in the antenna support device according to the second aspect of the present application, at least one of the pair of contact pieces constituting the antenna mounting member is provided with a locking protrusion so as to protrude toward the tip side from the insertion hole. It is done.

In the support, at least one of the pair of end surfaces is provided with an arrangement position limiting means.
The arrangement position restricting means includes a concave receiving portion into which the locking protrusion is inserted, and a fastening portion that is continuously provided from the opening of the receiving portion toward both sides and restricts the rotation of the support. And a rotating portion that is disposed on both sides outward from the fastening portion and receives the locking protrusion so as not to limit the rotation of the support.

As a result, according to the antenna support device of the second aspect of the present application, in a state where the bolt body is mounted so as to be positioned in the through hole, the locking protrusion and the receiving portion of the arrangement position limiting means are fitted. Therefore, the support can be disposed so that the antenna device accurately faces the front with respect to the antenna mounting member.

In addition, when the bolt body serving as the rotation axis of the support tool is at the intermediate position of the slide hole, the rotation of the support tool is restricted, and the antenna device cannot be adjusted in direction, and the bolt body is located at the end of the slide hole. When positioned, the direction of the antenna device can be adjusted.

That is, according to the antenna support device of the second aspect of the present application, when the direction of the antenna device is adjusted by rotating the support with respect to the antenna mounting member, the rotation axis (in other words, the rotation of the support device). Bolt body) must be moved to the end of the slide hole.

According to this configuration, when adjusting the direction of the antenna device, the size of the protruding portion of the antenna device located outside the rotation axis of the support can be shortened.
For this reason, when the antenna support device is installed on the wall surface, the rotation angle of the support tool, which is a range from the state in which the antenna device faces the front to the end portions of the antenna device overlap with the wall surface, is increased. it can.

Therefore, it is possible to cope with various installation conditions caused by the installation direction of the wall surface, the direction of arrival of radio waves, the signal quality of incoming radio waves, etc., and also eliminates unnecessary adjustment operations and shortens the installation time of the antenna device. Thus, an extremely convenient antenna support device can be provided.

Next, according to the antenna support device of the third aspect of the present application, between the other end surface of the support and the second intermediate position, the insertion port formed in the end surface is inserted through the slide hole and the communication hole. A notch is formed so as to communicate with the through hole.

The notch has a height dimension from the other end surface of the support body to the second intermediate position that is larger than a predetermined length in a range where the male thread portion of the bolt body is formed. The orthogonal width direction dimension is larger than the outer diameter of the male thread portion of the bolt body.

In addition, a guide part is formed on the inner wall of the communication hole to form a step having the same dimension as the width direction of the notch, and the guide part is supported from the slide hole side to the through hole side. Inclination is applied so that the dimension in the height direction from the other end face of the body to the step increases sequentially.

For this reason, according to the antenna support device of the third aspect of the present application, the male thread portion of the bolt body can be inserted as it is into the notch formed in the support body from the other end surface of the support body. Then, the male screw portion of the inserted bolt body hits the step of the guide portion formed on the inner wall of the communication hole, and is guided to the through hole by the inclination of the step.

Therefore, when inserting the bolt body from one insertion hole through the through hole to the other insertion hole, it is not necessary to position the bolt body, and the insertion work can be easily performed.

In the present embodiment, the intermediate support hole 12B is located between the step 12ab that is the first intermediate position and the notch 18 that is the second intermediate position.

The intermediate support hole portion 12B is a slide hole 13B corresponding to the intermediate support hole portion 12B of the slide hole 13 among the three holes (slide hole 13, communication hole 14, and through hole 15) constituting the support hole 12. The width dimension of the gap is larger than the outer diameter dimension Ws of the shaft part 30b of the bolt body 30, and is substantially the same as or shorter than the outer diameter dimension Wt of the male thread part 30a of the bolt body 30. It is formed as follows.

Further, the inner diameter of the through hole 15B corresponding to the intermediate support hole 12B portion of the through hole 15 is formed to have a size W1 larger than the outer diameter Wt of the male screw portion 30a of the bolt body 30. .

Further, the inner wall of the communication hole 14B corresponding to the intermediate support hole portion 12B has a dimension from the second intermediate position from the second intermediate position toward the first intermediate position, from the slide hole 13B side to the through hole 15B. An inclined step 34a is formed so as to increase sequentially.

And the guidance | induction part 34 is comprised by this level | step difference 34a and the mutually opposing plane 34b provided via this level | step difference 34a. The operation of the guide part 34 will be described in detail later.

That is, in the communication hole 14B corresponding to the intermediate support hole portion 12B, the width dimension of the space formed by the flat portion 34b constituting the guide portion 34 is the same dimension W1 as the width dimension of the gap of the notch portion 18. Whether the width of the gap of the communication hole 14B excluding the guide portion 34 is larger than the outer diameter Ws of the shaft portion 30b of the bolt body 30 and is substantially the same as the outer diameter Wt of the male screw portion 30a of the bolt body 30. Or, W2 is a short dimension.

As a result, the intermediate support hole portion 12B has a width dimension (inner diameter size) of the gap between the slide hole 13B and the communication hole 14B (excluding the guide portion 34 portion) corresponding to the intermediate support hole 12B portion of the slide hole 13 and the communication hole 14. ) Is W2, and the width dimension (inner diameter dimension) of the gap between the through hole 15B and the guide part 34 corresponding to the intermediate support hole 12B portion of the through hole 15 is W1. Will have.

In summary, according to the support hole 12 according to the present embodiment, the width dimension (inner diameter dimension) of the gap of the slide hole 13 constituting the support hole 12 is the dimension W1 of the slide hole 13A in the upper support hole portion 12A portion. The slide hole 13B in the support hole 12B portion has the dimension W2, and the slide hole 13C in the lower support hole portion 12C has the dimension W2. The width dimension (inner diameter dimension) of the gap between the slide hole 13B and the slide hole 13C is narrower than the slide hole 13A.

Further, the width dimension (inner diameter dimension) of the gap of the communication hole 14 is such that the communication hole 14A in the upper support hole 12A portion is the dimension W1, and most of the communication hole 14B except for the guide portion 34 in the intermediate support hole 12B portion. The gap is the dimension W2, and the communication hole 14C of the lower support hole 12C is the dimension W1.

The width dimension (inner diameter dimension) of the communication hole 14B in the intermediate support hole 12B portion is narrower than the width dimension (inner diameter dimension) of the gap between the communication holes 14A and 14C in most parts.
Further, the inner diameter of the through hole 15 is such that the through hole 15A of the upper support hole portion 12A has the dimension W1, the through hole 15B of the intermediate support hole 12B has the size W1, and the through hole 15C of the lower support hole 12C has the through hole 15C. The dimension W1 is the same dimension.

Next, the arrangement position restricting means 16A and 16B in the present embodiment will be described in detail with reference to FIGS. 1 and 2A-2F.
The arrangement position limiting means 16A and 16B are provided on the pair of end surfaces 11a and 11b of the support 11, respectively, so as to protrude upward or downward from the end surfaces.

The arrangement position restricting means 16A and 16B are means for restricting the arrangement state of the antenna mounting member 20 (in other words, the rotation of the supporting tool 10) in a state where the support tool 10 is supported by the antenna mounting member 20. It is provided on the end faces 11a and 11b so as to be arranged in a direction perpendicular to the axis of the support hole 12 and along the back surface 1a of the antenna device 1.

In the following description, the arrangement and action of the arrangement position limiting means 16A formed on one end face 11a will be described, and the arrangement position restriction means 16B formed on the other end face 11b will have the same structure. Therefore, detailed explanation is omitted.

Moreover, although the example which provided the arrangement | positioning position restriction | limiting means in each of a pair of end surface 11a * 11b was shown in this embodiment, it cannot be overemphasized that the structure provided in either one end surface may be sufficient.
The disposition position restricting means 16A is a concave portion disposed substantially at the center of the one end surface 11a, and includes a concave receiving portion 16Aa formed so as to open the rear side, and an opening end portion of the receiving portion 16Aa. A wall-like fastening portion 16Ab provided so as to be continuously provided outward on both sides, and formed so as to be further provided on the outer side of the fastening portion 16Ab and to have a curved shape with an opening at the rear side. And the rotating portion 16Ac. The operation of the arrangement position limiting means 16A and 16B will be described in detail later.

In addition, storage holes 11d and 11d that are formed so as to be directed forward from the surface 11c are formed at an intermediate position of the surface 11c of the support 11.
The storage holes 11d and 11d are formed at positions facing fastening bolts 45 (see FIG. 1) provided on a clamp fitting 40 attached to the antenna mounting member 20 described later. It has a depth and an inner diameter enough to accept the end portion 45a so that it can be inserted and removed.

Next, the antenna mounting member 20 constituting the antenna support device 50 according to the present embodiment will be described with reference to FIGS. 1 and 3A-3D. 3A to 3D schematically show the existence of the bolt body 30 and are displayed to show a state of being attached to the antenna mounting member 20.

The antenna attachment member 20 according to the present embodiment includes an attachment surface 22 for attaching the antenna device 1 to an attachment object on the back surface of the main body 21 formed in a substantially rectangular shape.
In addition, a pair of front surfaces of the main body 21 are integrally projected from a pair of opposite sides of the main body 21 so as to be slidably inserted into the pair of end surfaces 11 a and 11 b disposed opposite to the support 10. A pair of contact pieces 21a and 21b provided at intervals corresponding to the arrangement positions of the end faces 11a and 11b are formed.

The contact pieces 21a and 21b have insertion holes 29A formed so as to face each other across the support hole 12 formed in the support 10 when the support 10 is attached to the antenna mounting member 20. 29B are provided.

In addition, female screw portions 29a and 29b corresponding to the male screw portion 30a of the bolt body 30 are formed on the inner peripheral surfaces of the insertion holes 29A and 29B.
Further, the pair of contact pieces 21a and 21b are provided with locking protrusions 26A and 26B formed on a substantially square shape, which are formed so as to protrude toward the tip side from the insertion holes 29A and 29B. The contact pieces 21a and 21b are integrally provided so as to overlap with the tip portions of the contact pieces 21a and 21b.

In the present embodiment, the locking protrusions 26A and 26B are provided on both of the contact pieces 21a and 21b. However, at least the contact on the side corresponding to the end surface provided with the arrangement position limiting means 16 is provided. What is necessary is just to make it provide with a piece.

The mounting surface 22 of the antenna mounting member 20 will be described in more detail.
As well shown in FIGS. 1 and 3A-3D, the mounting surface 22 of the main body 21 is formed with a recess that is recessed so that the substantially central portion of the mounting surface 22 is folded back to the front side.

This concave portion is an antenna mast abutting portion 24 that is attached to a column represented by the antenna mast 5 and is one of the attachment objects shown in FIG.
Then, screw holes 25 are formed on both sides of the antenna mast abutting portion 24, and fastening bolts 45 provided in a well-known holding metal fitting 40 that holds the antenna mast 5 are tightened in the screw holes 25. Thus, the antenna mounting member 20 can be fixed to a support such as the antenna mast 5 or a veranda (see FIG. 10A).

Further, the planes on both sides of the antenna mast abutting portion 24 where the screw holes 25 are formed have the antenna mounting member 20 mounted on a wall surface 6 such as a structure as another example of the mounting target. It is the contact part 23 for attaching to the planar mounting surface represented. The antenna mounting member 20 is attached to the wall surface 6 in a state where the contact portion 23 is in contact with the wall surface, and wood screws or the like are attached to the wall surface 6 from the front side of the mounting holes 27 and 28 formed in the contact portion 23. (See FIG. 10B).

In the present embodiment, the abutting portion 23 and the antenna mast contact portion 24 constitute the mounting surface 22 provided in the main body 21. Further, at least the mounting surface 22 and the holding metal fitting 40 constitute the mounting means described in the claims.

A procedure for assembling the support 10 and the antenna mounting 50 configured as described above will be described with reference to FIGS. 4 to 8A-8B.
As shown in FIG. 4, the assembly of the support 10 and the antenna attachment 50 is performed by using the other provided on the antenna attachment member 20, which is a component of the antenna attachment 50 (in the present embodiment, the bottom of the figure). The male threaded portion 30a of the bolt body 30 is screwed into the female threaded portion 29b of the insertion hole 29B provided in the side abutting piece 21b, and the bolt body 30 is suspended from the other abutting piece 21b. Start by putting it on in a state. At this time, the maximum dimension of the portion where the bolt body 30 protrudes to the inside (upper side in the drawing) of the other abutting piece 21b is the dimension Ht in which the male screw portion 30a is formed.

The assembly of the support 10 and the antenna attachment 50 will be described in more detail. The operation of attaching the antenna device 1 to the wall surface 6 is performed after the antenna attachment device 50 is first fixed to the wall surface 6 due to the configuration of the antenna attachment device 50, and when the antenna device 1 is attached to a support such as the antenna mast 5 or the like. The procedure is different. Therefore, if the bolt body 30 is mounted in advance so as to be suspended from the other abutting piece 21b of the antenna mounting member 20, and the support 10 can be mounted on the antenna mounting 50 in this state. The mounting work of the support tool 10 is simplified.

Therefore, as shown in FIG. 4, a cutout portion 18 extending from the insertion port 18 a to the through hole 15 </ b> C is formed at the lower position of the support tool 10, and the support tool 10 is attached to the antenna mounting tool 50. In doing so, the male threaded portion 30a of the bolt body 30 that is mounted so as to hang down from the antenna mounting member 20 can be freely inserted into the notch 18, so that the male threaded portion 30a of the bolt body 30 is present. However, the mounting of the support 10 and the antenna attachment 50 is not disturbed.

In other words, the end surface 11a of the support 10 with respect to the contact pieces 21a and 21b of the antenna mounting member 20 mounted in a state where the bolt body 30 is suspended only by moving the support 10 in the direction of arrow F in the figure. 11b can be mounted while being slidably contacted, so that, for example, in a state where the support 10 is mounted on the antenna mounting member 20, the bolt body 30 is held by the antenna mounting member while holding the antenna device 1. A series of troubles such as screwing into the female screw portion 29b of the insertion hole 29B provided in the contact piece 21b can be reduced.

On the other hand, when the antenna device 1 is attached to a support such as the antenna mast 5, the support 10 and the antenna attachment member 20 (specifically, the antenna attachment 50) are attached before being attached to the antenna mast 5. At this time, a storage hole 11d is formed in the surface 11c of the support 11 so that the free end 45a of the fastening bolt 45 of the clamping bracket 40, which is fastened to the antenna attachment 50, can be inserted and removed. Therefore, the presence of the fastening bolt 45 does not get in the way when the support tool 10 is mounted on the antenna mounting tool 50. According to this configuration, since the free end 45a of the fastening bolt 45 is stored in the storage hole 11d in a state where the support 10 is mounted on the antenna mounting 50, the antenna mounting 50 is moved rearward from the support 10. The projecting dimension (more specifically, the depth dimension combined with the antenna device 1) can be reduced. Further, the cost can be reduced, for example, by reducing the packing material used at the time of product shipment.

The mounting state of the support tool 10 and the antenna mounting tool 50 at this time will be described in detail with reference to FIG. 6B.
In order to simplify the drawing, only the bolt body 30 indicating the presence of the antenna attachment 50 is shown in FIG. 6B.

As shown in FIG. 6B, when the support 10 is mounted on the bolt body 30 shown in the drawing so as to be moved in the direction of the arrow (1), the other contact piece of the antenna mounting member 20 is attached. It can be seen that the male threaded portion 30b of the bolt body 30 mounted in a state of depending on 21b is mounted so as to be freely inserted in the left-right direction of FIG. 6B due to the presence of the notch portion 18.

That is, the support 10 (that is, the antenna device 1) is slidably attached to the antenna attachment 50 in the front-rear direction (left-right direction in FIG. 6B).
On the other hand, the width dimension (inner diameter dimension) W2 of the gap of the slide hole 13C corresponding to the lower support hole 12C portion of the slide hole 13 is the same as the outer diameter dimension Wt of the male thread part 30a of the bolt body 30, or It is formed to have a slightly shorter dimension.

For this reason, even if the support tool 10 is moved in the direction of the arrow (2) with respect to the bolt body 30 shown in the drawing, the slide hole 13C prevents the male screw portion 30b of the bolt body 30 from entering. I understand.

That is, in a state where the bolt body 30 hangs down from the antenna mounting member 20, the support 10 (and thus the antenna device 1) moves in the left-right direction along the slide hole 13 </ b> C with respect to the antenna mounting member 20 (see FIG. 6B in the vertical direction) is limited.

Thus, the state which mounted | wore the antenna fixture 50 with the support tool 10 is shown by FIG. 5A.
As already described in detail, in the present embodiment, the notch 18 and the three holes (slide hole 13, communication hole 14, and through hole 15) constituting the support hole 12 portion formed in the support 10 are included. Only the through hole 15 is formed with an inner diameter dimension W1 slightly larger than the outer diameter dimension Wt of the male thread portion 30a of the bolt body 30.

Therefore, in the present embodiment, the bolt body 30 that is in a suspended state as shown in FIG. 5B from the mounting state shown in FIG. 5A is inserted into the insertion hole 29A provided in one abutting piece 21a. For screwing, the axis of the insertion hole 29B provided in the other abutting piece 21b, the axis of the through hole 15, and the axis of the insertion hole 29A provided in the one abutting piece 21a are approximately. This is possible only when they are matched.

As a method for making the axes substantially coincide with each other, when the support 10 is attached to the antenna attachment member 20, the male screw portion 30a of the bolt body 30 contacts the inner peripheral surface of the through hole 15C in the lower support hole portion 12C. This can be achieved by attaching the device as shown.

By the way, since the bolt body 30 of this embodiment is a half screw type in which the outer diameter of the shaft portion 30b of the bolt 30 is smaller than the inner diameter of the insertion hole 29B, the bolt 30 in a suspended state is shown in FIG. As indicated by the broken line, the lens is mounted in a state in which it can be largely tilted within the hole of the insertion hole 29B.

Therefore, in the present embodiment, the axial lines of the insertion holes 29A and 29B formed in the contact pieces 21a and 21b of the antenna mounting member 20 and the axial lines of the through holes 15 formed in the support tool 20 are substantially aligned. The guide portion 34 is provided so that the bolt body 30 does not tilt when the bolt body 30 is lifted upward.

That is, in the present embodiment, the bolt body 30 is brought into contact with the lower opening of the communication hole 14B in the lower support hole 12C (in other words, the upper inner wall of the notch 18), etc. The guide portion 34 is provided on the second intermediate position side of the communication hole 14B so as not to hinder normal assembly.

As described above, the formation dimension of the guide part 34 is the same as the width W1 of the gap in the space formed by the flat surface 34b constituting the guide part 34 as the width of the gap in the notch part 18.
Further, the width dimension of the communication hole 14B excluding the guide part 34 is larger than the outer diameter dimension Ws of the shaft part 30b of the bolt body 30, and is substantially the same as the outer diameter dimension Wt of the male thread part 30a of the bolt body 30. Alternatively, it is formed to have a short dimension W2.

Further, the step 34a of the guide part 34 is formed so as to be inclined so as to converge to the through hole 15B in the intermediate support hole part 12B as it goes from the second intermediate position to the first intermediate position.

Accordingly, the guide portion 34 receives the male screw portion 30a portion of the bolt body 30 up to the space formed by the flat surface 34a, but the step 34a prevents insertion of the bolt body 39 into the communication hole 14B with respect to the male screw portion 39a. However, the insertion of the through hole 15B in the axial direction is guided.

For this reason, the operation | work at the time of screwing the bolt body 30 in the insertion hole 29A formed in the one contact piece 21a can be performed easily.
The mounting state of the support 10 and the antenna mounting member 20 (in other words, the antenna mounting 50) at this time will be described in detail with reference to FIGS. 6A and 7A-7C.

7A-7C show the presence of the other abutting piece 21b provided on the antenna attaching member 20 and the bolt body 30 attached to the abutting piece 21b. FIG. Only the bolt body 30 indicating the presence of the tool 50 is displayed.

As shown in FIG. 7B, from the state where the bolt body 30 hangs down from the abutting piece 21b provided on the antenna mounting member 20, the bolt body 30 is inserted into the through-hole 15B as shown in FIGS. 6A, 7A and 7C. Consider a case in which the bolt body 30 is inclined to be inserted into the bolt.

In this case, a space formed by the flat surface 34b of the guide portion 34 and having a gap width dimension W1 receives the male threaded portion (outer diameter dimension Wt) 30a of the bolt body 30.
However, the tip of the male threaded portion 30a comes into contact with the stepped portion 34a arranged so that the width dimension of the gap is W2, and the stepped portion 34a slides the male threaded portion 30a of the bolt body 30 in the direction of arrow U in FIG. 7A. Since it is guided while being brought into dynamic contact, the bolt body 30 is correctly inserted in the axial direction of the through hole 15B.

Next, a state where the bolt body 30 is mounted will be described with reference to FIGS. 5B and 8A-8B.
As described above, the first intermediate position that is the formation range of the upper support hole portion 12 </ b> A, that is, the step 12 ab is at least from the opening end 12 a of the support hole 12 on one end surface 11 a of the support body 11. It is formed at a position where the dimension Hs is larger than the dimension Ht in the range where the male screw portion 30a is formed (see FIG. 4).

Further, the width dimension (inner diameter dimension) of the gaps of the three holes (slide hole 13A, communication hole 14A, and through hole 15A) constituting the upper support hole part 12A are all outer diameters of the male thread part 30a of the bolt body 30. The dimension W1 is larger than the dimension Wt.

For this reason, in a state where the support 10 is completely attached to the antenna attachment 50 (that is, the attachment of the bolt body 30 is completed), as shown in FIG. 8A, the male thread portion of the bolt body 30 The 30a portion is not only mounted loosely in the internal space of the through hole 15A, but also as shown by the presence of the bolt body 30A in the drawing, from the communication hole 14A constituting the upper support hole portion 12A to the slide hole 13A. It is mounted so that it can be freely inserted even in the internal space leading to.

Further, the width dimension (inner diameter dimension) of the gap between the three holes (slide hole 13B, communication hole 14B, and through hole 15B) constituting the intermediate support hole 12B is the space part (dimension) formed by the flat surface 34a in the guide part 34. W1) and the through-hole 15B (dimension W1) are larger than the outer diameter dimension Ws of the shaft part 30b of the bolt body 30 and substantially the same as the outer diameter dimension Wt of the male thread part 30a of the bolt body 30, or , Formed to have a short dimension W2.

For this reason, in a state where the support 10 is completely attached to the antenna fixture 50, as shown in FIG. 8B, the shaft portion 30b portion of the bolt body 30 is loosely inserted in the internal space of the through hole 15B. As shown by the presence of the bolt body 30A in the drawing, it can be freely inserted in the internal space from the communication hole 14B constituting the intermediate support hole 12B to the slide hole 13A. Installed.

Of the three holes (slide hole 13C, communication hole 14C, and through hole 15C) constituting the lower support hole 12C, the communication hole 14C constituting the notch 18 and the width of the gap (inner diameter) Only the slide hole 13C excluding the through hole 15C is larger than the outer diameter dimension Ws of the shaft part 30b of the bolt body 30, and is substantially the same as or shorter than the outer diameter dimension Wt of the male thread part 30a of the bolt body 30. It is formed to be W2.

For this reason, in the state in which the support 10 is completely attached to the antenna fixture 50, as shown by the bolt body 30A in FIG. 6C, the shaft portion 30b portion of the bolt body 30 constitutes the lower support hole portion 12C. It is mounted so that it can be freely inserted in the internal space of the slide hole 13C.

In other words, in the present embodiment, the support 10 (and thus the antenna device 1) is screwed in a state where the mounting to the antenna mounting 50 is completed (that is, the bolt body 30 is not tightened). In the mounting state of the support and the antenna attachment 50. Hereinafter, this mounting state is referred to as a first mounting state.) Even if the guiding portion 34 is present, the guiding portion 34 is the shaft portion 30b of the bolt body 30. On the other hand, there is a gap having a width W2 that allows insertion in a direction perpendicular to the axis of the through hole 15B.

Therefore, the support 10 (and thus the antenna device 1) slides freely in the directions (3) and (4) indicated by arrows in FIG. 6A while being along the support hole 12 with respect to the antenna fixture 50. It becomes possible.

Therefore, the position of the bolt body 30 that is the rotational axis of rotation of the support tool 10 can be moved to any position within the formation range of the support hole 12, and the antenna device can be adjusted in an arbitrary position. become.

Here, based on FIGS. 9A-9B to 11A-11B, the antenna mounting member 20 and the arrangement position restricting means 16A in a state where the support 10 (and hence the antenna device 1) and the antenna mounting 50 are mounted. -The relationship with 16B will be described in detail.

In the following description, in order to simplify the description of the relationship between the antenna mounting member 20 and the arrangement position restriction means 16, an example of the arrangement position restriction means 16A formed on the one end face 11a side will be described. And since the other end surface 11b side is the same structure, description is abbreviate | omitted.

As described above, the attachment operation of the support 10 and the antenna attachment 50 is performed by the axis of the insertion hole 29B provided on the other attachment piece 21b protruding from the antenna attachment member 20 (in other words, the attachment attachment). This is performed only when the axial line of the bolt body 30 attached to the piece 21, the axial line of the through-hole 15, and the axial line of the insertion hole 29 </ b> A provided in the one abutting piece 21 a are substantially matched. be able to.

Then, the alignment can be performed by bringing the male screw portion 30a of the bolt body 30 into contact with the inner peripheral surface of the through hole 15C of the lower support hole portion 12C.
Furthermore, in the antenna support device 60 of the present embodiment, in the first mounting state in which the support 10 has been mounted on the antenna mount 50, as shown in FIG. The engaging protrusion 26A provided at the tip of the abutting piece 21a and the receiving portion 16Aa, which is a component of the arrangement position limiting means 16A formed on the one end surface 11a of the support 11, are fitted. It is configured as follows.

Further, in this first mounting state, the axis of the insertion hole 29B provided in the other abutting piece 21b (in other words, the axis of the bolt body 30 attached to the abutting piece 21) and the through hole A method of bringing the male screw portion 30a into contact with the inner peripheral surface of the through-hole 15C by configuring the 15 axial lines to coincide with the axial line of the insertion hole 29A provided in the one abutting piece 21a. In addition to this, the axes can be more accurately matched, and in addition to the presence of the guiding portion 34, the structure has excellent operability.

Next, referring to FIG. 8A, FIG. 9A and FIG. 11A, the locking projection piece 26A provided at the tip of one abutting piece 21a in the antenna mounting member 20 and the constituent elements of the arrangement position limiting means 16A A relationship with a certain fastening portion 16Ab will be described.

Note that the difference between the antenna mounting member 200 and the antenna mounting member 20 of the modification shown in FIG. 11A is the presence or absence of a locking protrusion, and the antenna mounting member 200 is not provided with a locking protrusion.

Further, the difference between the support tool 10A and the support tool 10 in the modification shown in FIG. 11A is the presence / absence of the placement position restriction means 16, and the support tool 10A is not provided with the placement position restriction means.
In the embodiment shown in FIG. 11A, neither the locking projection piece nor the arrangement position restricting means is provided. Therefore, the antenna mounting member 200 in the first mounting state shown by the solid line in FIG. For example, the antenna mounting member 200 'shown by a two-dot chain line can be rotated with respect to 10A.

Further, the mounting state indicated by the one-dot chain line (that is, the mounting state when the bolt body is disposed at the intermediate position of the slide hole 13 (in the following description, the state where the support member is mounted at the intermediate position of the slide hole is the first state). 2), the antenna mounting member 200A can be rotated with respect to the support 10A as illustrated.

Here, considering the case where the antenna attachment member 200 of this modification is attached to a wall surface that is an attachment object, for example, the rotation angle of the antenna attachment member 200A in the second attachment state is the side surface 1b of the antenna device 1. 11 (in other words, both side end portions of the back surface 1a) is in a range until the virtual wall surface position 6a shown by 6a in FIG. 11A comes into contact (angle α = 45 ° shown in FIG. 11A, for example). .

On the other hand, the rotation angle of the antenna mounting member 200 in the first mounting state is a range until the antenna mounting member 200 contacts the support 10A.
That is, according to the antenna support device of the modified example, the support tool 10A (and thus the antenna device 1) is located at any position of the support hole 12 provided in the support tool 10A with respect to the antenna mounting member 200. Since it can be rotated, it is convenient for adjusting the direction of the antenna device 1.

However, if the rotation angle (that is, the azimuth angle adjustment range of the antenna device) is limited in a narrow state due to the positional relationship between the installation location and the radio wave arrival direction, or characteristics unique to digital broadcast reception, the antenna device When the direction adjustment of 1 is performed, the direction cannot be accurately adjusted only by a single arrangement operation, and a further adjustment operation for the support 10 may be required.

More specifically, in the case of receiving terrestrial digital broadcasting, the direction adjustment of the antenna device 1 is not only adjusted to the direction in which the reception level (C / N) of the terrestrial digital broadcast signal received by the antenna device 1 is maximized. This is because it is desirable to check the signal quality (BER, MER, etc.) of the broadcast signal using a measuring instrument or the like.

In other words, depending on the environmental conditions of the propagation path of radio waves, for example, radio waves with poor signal quality may arrive even if the reception level is high. Because directing in the direction of the tower that transmits the signal may not always point the antenna device 1 in the correct direction (the direction in which the reception level, BER, and MER are all good values). is there.

Therefore, the antenna support device can not only adjust the direction of the antenna device 1 physically (in the direction of the radio tower) with an accurate azimuth angle, but also adjust the direction further in the left-right direction based on the physical azimuth angle. In view of the necessity to be able to find the correct direction electrically, it is desirable that the direction adjustment angle of the antenna support device can cover as wide a range as possible.

Therefore, as shown in FIG. 9A, the antenna support device 60 according to the embodiment of the present invention includes at least the locking protrusions 26A in the first mounting state by providing the support 10 with the arrangement position limiting means. The receiving portion 16Aa is fitted and the support 10 cannot be rotated.

On the other hand, as shown in FIG. 8A, from the first mounting state, the support 10 is slid from the direction (3) of the arrow in the figure to the direction (4) of the arrow, and the bolt body is positioned at the intermediate position of the slide hole 13. In the second mounting state in which 30A is provided, as shown by the existence of the virtual antenna mounting member 20A indicated by the one-dot chain line in FIG. 9A, the front end of the locking protrusion 26A and the fastening portion 16Ab are aligned. Opposed.

Therefore, in the first mounting state and the second mounting state, the support 10 cannot be rotated with respect to the antenna mounting member 20.
That is, in a state where the support 10 has a range of rotation angles that is not so large with respect to the antenna mounting member 20 (in other words, until it can be rotated within the range of the maximum rotation angle), the antenna device 1. It is assumed that the direction cannot be adjusted.

As a result, in the operation for adjusting the direction of the antenna device 1, the possibility that the antenna device 1 cannot be directed in the correct direction even if the antenna device 1 is accurately directed to the physical azimuth angle can be reduced. As a result, the installation work of the antenna device 1 can be shortened.

Next, with reference to FIG. 9B and FIG. 10B, the relationship between the locking protrusion 26 </ b> A and the rotation portion 16 </ b> Ac that is a component of the arrangement position limiting means 16 </ b> A will be described.
As shown in FIG. 9B, when the support tool 10 is slid in the direction of the arrow S in the figure to the position of the antenna attachment member 20B indicated by the broken line in the figure, specifically, the antenna attachment member 20B. The mounting state in which the bolt body 30B is located at the terminal portion 13D on the upper side of the figure in the slide hole 13 (in the following description, the state in which the bolt body 30B is mounted on the terminal portion 13D of the slide hole 13 is the third mounting state) In the following description, the space of the rotating portion 16Ac receives the tip end portion of the locking projection piece 26A while the support tool 10 is rotated.

For this reason, in the third mounting state, the support 10 can be rotated with respect to the antenna mounting member 20 about the terminal end portion 13D as the rotation axis (the antenna indicated by the two-dot chain line located on the lower side of the figure). The mounting member 20C is similarly mounted).

That is, according to the antenna support device 60 in the present embodiment, as shown in FIG. 9B, in the third mounted state, the antenna located outside (upper side in the drawing) from the axis of the terminal end portion 13D of the slide hole 13. Since the dimension L1 of the protruding part of the device 1 can be shorter than the dimension L2 of the protruding part in the second mounting state shown in FIG. 11A, the rotation angle θ of the support 10 (shown in FIG. 9B). The angle θ = for example 60 ° can be increased.

Therefore, the antenna device 1B indicated by the broken line in FIG. 10B and the antenna device 1C indicated by the two-dot chain line can increase the direction adjustment range of the antenna device even when installed on the wall surface 6 or the like. It is also possible to cope with various installation conditions caused by the installation direction, the arrival direction of radio waves, the signal quality of incoming radio waves, and the like.

Also, since the direction adjustment range is large, useless adjustment operations can be eliminated, and the installation time of the antenna device can be shortened. That is, according to the present embodiment, it is possible to provide the antenna support device 60 that is extremely convenient.

In addition, this invention is not limited to the said embodiment, A various aspect can be taken in the range which does not deviate from the meaning of this invention.
For example, as shown in FIG. 11B, a combination of the antenna mounting member 20 that is an embodiment of the present invention and a support 10B that is a modification of the support 10 may be used. The difference between the support tool 10B and the support tool 10 is the configuration of the arrangement position limiting means.

Although the disposition position limiting means 160A provided in the support 10B of this different embodiment has a receiving portion 160Aa for receiving and fitting the locking protrusion 26A as shown in FIG. 11B, it has been described above. The arrangement position control means 16A does not include the fixing portion and the rotation portion provided.

That is, the first mounting state of the support 10B and the antenna mounting member 20 of this modification is that the locking protrusion 26A is fitted into the receiving portion 160Aa, so that the support 10B (and thus the antenna device 1). Can be fixedly arranged in a state of being low in profile and facing the antenna mounting member 20.

On the other hand, in both the second mounting state (antenna mounting member 20A indicated by a broken line in the figure) and the third mounting state (antenna mounting member 20C indicated by a two-dot chain line in the figure), the support 10B (extension) In this case, the antenna device 1) can be pivotally fixed to the antenna mounting member 20.

According to this embodiment, since the direction can be adjusted at an arbitrary position in the slide hole 13, the dimension of the antenna device 1 protruding from the wall surface of the structure or the like can be further shortened.
In the above embodiment, the guide hole 34 is provided in the communication hole 14 of the support 11 by inclining the step 34a. However, as shown in FIGS. 12A-12B, the guide 34 is not necessarily formed. do not have to.
