Description

[Detailed explanation of the idea] The present invention relates to an improvement of a roof horse for an antenna.

Conventional roof horses of this type had four legs fixed around a cylindrical body portion that held the antenna support, so the support could tilt due to errors in manufacturing and assembly of the roof horse or the condition of the roof. This has been corrected by changing the location where the roof horse is installed or by placing something between the legs and the roof, but the problem is that the correction work is cumbersome and time-consuming. Particularly in the case of a pole-mounted satellite broadcast receiving antenna that uses an antenna with sharp directivity, such as a parabolic antenna or an offset parabolic antenna, the positioning of the antenna with respect to the satellite is performed separately in terms of elevation angle and azimuth angle.
For this purpose, it is necessary to install the support columns in the correct vertical direction, which makes the correction work even more difficult.

In view of the above-mentioned points, the present invention allows the support to be easily and reliably set in a predetermined direction, for example, in the vertical direction.
Another object of the present invention is to provide a roof horse that can be easily folded and convenient for transportation and storage. In order to achieve this purpose, in the antenna roof horse of the present invention, the middle of the legs bent in an inverted V shape is rotatably attached to both ends of the support seat, and a half-tube is attached to the top of each leg. Half-shaped support gripping pieces with mounting seats with vertical holes protruding from both sides of the body are connected so as to be movable up and down, and both support support gripping pieces are screwed into bolts inserted into the vertical holes with nuts. A receiver tube is provided in the support seat to loosely fit the lower end of the column held by both support support pieces, and a plurality of set bolts are arranged around the circumference of the receiver tube, and at least one of the opposing legs is connected to the support tube. A leg length adjustment mechanism is provided at the end of the leg.

Embodiments of the present invention will be described below based on the drawings. In Figures 1 to 3, 1 is the support seat;
A receiver tube 3 into which the lower end of the support column 2 is loosely fitted is protruded from the center upper surface of the rectangular flat plate, a plurality of screw holes 4 are penetrated through the circumference of the receiver tube, and a set bolt 5 is attached to the tube.
Bearing portions 8, 8 are provided protruding from both ends of the rectangular flat plate, respectively. The legs 6, 6 are made into an A-shape as shown in FIG. 2 by bending the pipe into an inverted V-shape and reinforcing the middle with a connecting pipe 7, and furthermore, when viewed from the side, they are square-shaped as shown in FIG. 1. Then, it is rotatably attached to the bearings 8, 8 of the support seat 1 with the connecting pipe 7, and
Locking protrusions 9, 9 along both bearings 8, 8 are attached to the connecting pipe 7 to prevent the leg 6 from moving laterally with respect to the support seat 1. At the top of the leg 6, a half-shaped support gripping piece 13 is provided, which is formed by integrally protruding mounting seats 12 having a plurality of longitudinal holes 11 on both sides of a semi-cylindrical body part 10 that follows the external shape of the support 2. It is mounted so as to be movable up and down by means of a support shaft 14 inserted through a member protruding from the center of its back surface. Adjustment screws 15, 15 as a leg length adjustment mechanism are screwed into the leg ends of one side of the legs 6, 6 facing each other to make the leg length variable.

Since the present invention has the above-mentioned configuration, the fourth
As shown in the figure, the legs 6, 6 in the folded state are opened, and the bolt 16 is inserted into the vertical hole 11 of the pair of support gripping pieces 13, 13, and the nut 17 is slightly screwed into the bolt 16. A horse is placed on the roof, for example, as shown in FIG. 1, straddling the ridge.
To attach the strut 2 to this roof horse, the strut 2 is first inserted into the pair of strut gripping pieces 13, 13, and then the lower end of the strut 2 is inserted into the receiver pipe 3 and brought into contact with the strut seat 1. In FIG. 1, when the pair of strut grip pieces 13, 13 are viewed from the side, the strut 2 is moved in a predetermined direction,
For example, if it is not in the vertical direction, move the column 2 to correct the collapse in the left and right direction. At that time, the roof seating position of the leg 6 and the height position and inclination angle of the strut gripping piece 13 may change, but the strut gripping piece 13
Since it is attached so that it can move up and down, it can be placed along the column 2, and the opposing column gripping piece 1
Even if there is a slight deviation in the height positions of 3 and 13, the bolt 16 is inserted into the vertical hole 11, so
It is possible to clamp the column 2 by the column gripping pieces 13, 13 even if there is a deviation. After the strut 2 oriented in a predetermined direction is clamped between the pair of strut gripping pieces 13, 13, the lower end of the strut 2 is set in the receiving pipe 3 with the set bolt 5. As a result, the pillars 2 can be firmly fixed at two locations in the center of the roof horse. next,
Check the tilting of the column 2 in the left and right direction from the direction shown in FIG. 2, which is 90 degrees different from the direction shown in FIG. uniformly raise and lower the pillar 2
taken in the vertical direction. Both adjustment screws 15, 15 are right-handed screws and have the same pitch, so if they are turned in the same direction and by the same amount, they will move up and down by the same height. When the posture of the support column 2 is adjusted in both the X and Y directions in this manner and the support column is correctly positioned in a predetermined direction, the roof horse is fixed to the roof using appropriate known means.

As explained above, according to the present invention, when a post inserted into a pair of post gripping pieces connected to each other in an opening position is fixed to a pair of leg lengths in a predetermined direction when viewed from one side, the next time the post is viewed in a different direction by 90 degrees. Since the leg length adjustment mechanism is used to set the support in a predetermined direction, the support can be set on the roof relatively quickly and easily. Furthermore, when the two strut grip pieces are uncoupled and one leg is suspended, the strut receiver and the other leg rotate and can be folded flat as shown in Figure 4, which is convenient for transportation and storage. becomes.
