[0001]

BACKGROUND OF THE INVENTION The present invention relates to a device for supporting a television antenna mounted on a roof of a house.

[0002]

2. Description of the Related Art As is well known, when a television antenna is installed on a roof of a house, a support is installed so as to straddle the ridge of the roof, and a support for the antenna is mounted on the support. A tip of a support wire pulled out from a support base in three or four directions is locked to a support fitting attached to the eaves and supported by the support wire.

[0003]

[Problems to be Solved by the Invention] In recent years, for the purpose of energy saving, a solar cell for solar power generation has been installed on a roof of a house.
When such a solar cell is installed on a roof surface, if the light receiving surface of the solar cell is shaded, there is a problem that an internal electric circuit is in a so-called broken state, and power cannot be generated. However, as described above, in the conventional TV antenna support device, since the wire extends in four directions or three directions and crosses the roof surface, the shadow of the support wire is applied to the light receiving surface of the solar cell. There's a problem. In addition, there is a problem that the support device can be attached only to the roof ridge, and it is difficult to stretch the wires around the solar cells.

[0004] In view of such conventional disadvantages, the present invention can fix a television antenna at almost any position on a roof surface, and makes it impossible to generate power by shading the light receiving surface of a solar cell. It is an object of the present invention to provide a support device for a television antenna that does not require a special wire.

[0005]

In order to solve the above-mentioned problems, according to the present invention, first, a plate-shaped base plate fixed to a roof surface with bolts, and a lower end of the antenna support standing upright from the base plate. Support post for inserting and fixing the L-shaped support bracket
Consists of

Then, the horizontal piece at the lower end of the support bracket is attached to the roof.
In the state of being locked to the lower surface of the purlin, remove the vertical piece of this support
Fix it to the side of the roof purlin by nailing, etc.
It is conceivable that a bolt tip projecting upward from the tool penetrates the base plate and the roof material and projects toward the roof surface side, and the base plate is fixed with the bolt tip.

[0007]

As described above, the antenna support of the support device is
Because it is directly attached to the roof surface with bolts,
The antenna can be mounted at almost any position as long as the bolt can be protruded, and there is no need to stretch the support wire.

FIG. 1 shows a support (1) of the present invention. In the figure, (2) is a base plate formed in a substantially square shape with corner portions cut, and bolt holes (3) (3)... Are formed in four corner portions thereof. At the center of the base plate (2), a support post (4) made of a hollow pipe is erected. Reference numeral (5) denotes a reinforcing pipe shorter than the support post (4). The reinforcing pipe is fitted to the support post (4) and its lower end is fixed to the base plate (2) by welding or the like. (6) (6) are a plurality of triangular reinforcing plates, one of which is fixed to the outer surface of the reinforcing post (5) and the other is fixed to the base plate (2). 4) The strength of the lower end fixing portion is increased. When the support post (4) and the base plate (2) are installed on the inclined surface of the roof, they are fixed to each other with an inclination angle so that the support post (4) rises vertically. Further, as shown in FIG. 3, three bolt holes (7) are formed in the support post (4) at equal intervals in the circumferential direction, and one set of the three bolt holes (4) is formed. Are formed in three stages, upper and lower.

FIG. 2 shows the mounting structure of the support base (1). First, a bolt (11) is inserted from below into a mounting bracket (10) mounted on a roof purlin (9) and (9). At the same time, the tip of the bolt (11) protrudes upward through a roof board (12) fixed to the upper surface of the roof purlin (9) and a roof material (13) made of a color vest.
The four bolts (11) are provided corresponding to the positions of the bolt holes of the base plate (2), and the cushion material (13) is provided below the base plate (2) to absorb irregularities of the roof material (13). The tip of the bolt (11) projects upward from the bolt hole (3) of the base plate (2) with the interposition of (14). Then, the base plate (2) is fixed to the roof surface by screwing and tightening a nut (15) to the tip of the bolt (11).
In this case, since the base plate (2) is fixed to the roof purlin (9) via the bolt (11) and the bracket (10), an extremely strong mounting structure is obtained.

Further, the support column (17) shown in FIG. 6 is inserted into the support post (4) from above, and the screw holes (7) (7) are arranged as shown in FIG.
.. Are pressed and fixed in three directions by holding bolts (18) screwed into.

FIGS. 4 and 5 show the structure of the support fitting (10) attached to the roof purlin (9) and details of the attachment. The support bracket (10) includes a mounting plate (20) formed in an L-shape when viewed from the side, and an inverted U-shaped bolt protruding outward from an upper end outer surface of the mounting plate (20). And a receiving member (21). The support plate (20) is nailed from the side so that the vertical piece (31) abuts on the outer surface of the purlin (9) and the horizontal piece (23) at the lower end abuts on the lower surface of the roof purlin (9). And fixed. At this time, since the horizontal piece (23) at the lower end is in a state of being locked to the lower surface of the roof purlin (9), a sufficiently high resistance to the upward pulling force can be obtained.

The bolt receiving member (21) has the U-shaped open portion facing upward, and the support plate (20)
The bottom portion has an elongated bolt hole (24) formed in the width direction of the purlin (9). (25) forms a bolt hole (26), and
As shown in FIG. 5, a nut (30) is a washer plate to which a nut (30) is fixed in advance, and a bolt (11) inserted from below into an elongated bolt hole (26) of the bolt receiving member (21). When the tip is screwed into the nut (30) through this bolt hole (26) and rotated, the washer plate (25)
However, rotation is prevented by abutting against the inner surface of the U-shaped bolt receiving member (21), whereby the screw is screwed only by rotating the bolt (11) from below. You can do it. At the time of this screwing, the tip of the bolt (11) is
It penetrates the bolt hole (27) formed in 2) and protrudes upward. In this way, first, bolts (11) are put in advance on the base plate (12)
In a state of being more protruded, the roofing material (13) is set in advance while being formed in the roofing material (13) or through a hole formed in place, and the base plate (2) is mounted as described above. It is fixed.

FIG. 6 shows a state in which a television antenna is mounted by the support base (1).
8) is a solar cell installed on the roof in the girder direction, and the TV antenna (29) is installed on the wife's roof at right angles to this roof, and the antenna (29) and its support ( The shade of 17) is selected and installed so as not to cover the solar cell (28).

[0014]

As described above, according to the present invention, the support for supporting the antenna can be installed at almost any position on the roof surface, and therefore, when the solar cell is installed on the same roof, However, since it is possible to select and install a position where the antenna is not shaded, there is no inconvenience that power cannot be generated due to the antenna. Of course, since there is no wire, there is no inconvenience that the shade of the wire is applied to the solar cell. In addition, due to the absence of wires, even when installing solar cells after antenna installation,
There is no drawback that the work is difficult because of the wire. Furthermore, in the case where the wire can be extended in three directions or four directions, it was necessary to attach the support fittings to the four places of the eaves respectively. Since all operations can be performed at the same location, workability for mounting the antenna is good. In addition, support the bolts
