Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an article attachment tool used when attaching an article such as an antenna to a member to be attached such as a rain gutter of an automobile.

BACKGROUND ART Conventionally, as shown in FIG.
When attaching the antenna 3 to the antenna, a mounting tool as shown in FIG. 5 was used.

In the figure, 4 is a bracket, 9 is a hexagon socket head screw, 10 is a base, 12 is an article mounting hole, and 13 is a hexagon socket head bolt.

The bracket 4 is provided with mounting pieces 6, 6' defined by a substantially U-shaped opening 5.
The bracket 4 is constructed by screwing a hexagon socket head screw 9 into a screw hole 7 formed in the mounting piece 6, and tightening the gutter 2 provided on the automobile 1 from both upper and lower sides using the mounting piece 6' and the hexagon socket head screw 9. It is fixed to the gutter 2 by. In addition, the hexagon socket head cap screw 1 is attached to the bracket 4.
3 is loosely inserted into the opening 8.
The bolt 13 has a two-stage shape, including a portion into which only the threaded portion of the bolt 13 is loosely inserted and a portion into which the head is loosely inserted. The base 10 is provided with a screw hole (not shown) at the side end of the shaft portion 11 to be screwed into a hexagon socket head bolt 13. By being screwed and fixed to the side of the bracket 4 by the bolt 13,
An antenna 3 is attached to the gutter 2 as shown in FIG.

When fixing the base 10 to the bracket 4, the mounting angle of the base 10 to the bracket 4 should be adjusted depending on the required angle of inclination of the antenna in the horizontal direction (direction perpendicular to the plane of the paper with respect to FIG. 4). adjust.

Problems to be Solved by the Invention However, in such a conventional configuration, the threading force between the hexagon socket head bolt 13 and the screw hole of the base 10 decreases due to vibration, wind pressure corrosion, etc., making it difficult to tighten the hexagon socket head bolt 13. If the antenna becomes loose, the base 10 rotates around the axis of the shaft portion 11, causing the antenna 3 to fall down and be destroyed.

In addition, as a means to solve such problems, as seen in Japanese Utility Model Publication No. 52-49768, arcuate grooves and protrusions are provided on the bracket and the base, respectively.
Some devices restrict the amount of mutual angular displacement between the bracket and the base by engaging the arcuate groove with the protrusion.

However, in such a configuration, when the bracket is attached to the gutter of a vehicle, the angle at which the bracket is attached changes depending on the shape of the gutter, so the arcuate groove is shortened to reduce the amount of mutual angular displacement between the bracket and the base. If the antenna is made smaller, it may not be possible to mount the antenna at a desired angle depending on the mounting angle of the bracket. Furthermore, if the arcuate groove is lengthened to increase the amount of mutual angular displacement described above, when the screwing force between the bracket and the base decreases as described above, the mounting angle of the antenna will change significantly, causing the vehicle There was a problem that the antenna would fall outward from the width of the vehicle, damaging the antenna.

The present invention is intended to solve these problems.

Means for Solving the Problems In order to solve the above problems, the present invention consists of a bracket having fixing means for fixing it to the vehicle, and a base to which the antenna is attached and fixed by screws to the side of the bracket. In the vehicle antenna mounting device, one of the bracket and the base is provided with a convex portion, and the other is engaged with the convex portion to regulate mutual angular displacement of the vehicle and the base within substantially the same range. A plurality of recesses are provided corresponding to the mounting angle of the bracket, and the base is fixed to the bracket with screws in a state where the projection and one of the plurality of recesses are selectively engaged. It is characterized by the following structure.

Embodiments of the invention Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the article mount according to the present invention, and parts denoted by the same reference numerals as in FIG. 5 have the same functions.

In the figure, a protrusion 21 is formed on the bracket 4 in accordance with the mounting position of the base 10, protruding toward the center of the opening 8. The base 10 has a recess 22 formed toward the center of the shaft 11 so as to engage with the protrusion 21 in accordance with the forming position of the protrusion 21.
The length of the recesses 22, 22' in the circumferential direction of the shaft portion 11 is set to be somewhat larger than the length of the protrusions 21 so that the inclination angle of the article attached to the base 10 can be adjusted and so that loosening of the hexagon socket head bolts 13 can be detected by the inclination of the base 10 relative to the bracket 4.

With this configuration, when attaching the base 10 to the bracket 4, the protrusion 21 is loosely fitted into the recess 22 with an article (not shown) such as an antenna attached to the base 10 through the article attachment hole 12. After loosely inserting the hexagon socket head bolt 13 into the opening 8 of the bracket 4, it is screwed into the screw hole 14 of the base 10 to be tightened and fixed. To attach the bracket 4 to a member (not shown) such as a gutter, screw the hexagon socket head screw 9 into the screw hole 7 and connect the mounting piece 6' and the hexagon hole in the same manner as explained in FIG. This is done by tightening the attached member from both the upper and lower sides using the mounting screws 9.

According to this configuration, even if the screwing force between the hexagon socket head bolt 13 and the screw hole 14 of the base 10 decreases due to vibration, wind pressure, corrosion, etc., and the tightening by the hexagon socket head bolt 13 becomes loose, the convex portion 21 engages with the wall surface of the base 10 forming the recess 22 to regulate the angle of inclination of the base 10 with respect to the bracket 4, thereby preventing the article attached to the base 10 from falling over and damaging the article. Things will disappear.

In this embodiment, the reason why the base 10 is fixed with the brackets 4 from both sides is to strengthen the fixing force of the brackets 4 to the object to be mounted. There may be only one 4.

In addition to the recess 22, the base 10 also has a recess 22'.
As shown in Fig. 2, the attached member 3
When fixing the bracket 4 to the attached part 30 with the mounting pieces 6 and 6' upright relative to the
By engaging the convex portion 21 and the concave portion 22' shown in the figure, it is possible to limit the angle of inclination of the base 10 due to loosening of the hexagon socket head bolt 13, and on the other hand, as shown in FIG. Using the auxiliary bracket 40 having a substantially L-shaped key part 41, the bracket 4
When the base 10 is fixed to a member to be attached, the angle of inclination of the base 10 can be limited by the engagement between the convex portion 21 and the concave portion 22.

It should be noted that the present invention is not limited to this embodiment, and the shapes of the bracket 4 and the base 10 may be set depending on the shape, size, etc. of the member to be attached and the article. The structure for fixing the bracket 4 to the bracket 4 is not limited to tightening and fixing with screws, but may also be, for example, adhesive.

Effects of the Invention As explained in detail above, according to the vehicle antenna mount according to the present invention, one of the bracket and the base is provided with a convex portion, and the other is engaged with the convex portion, thereby attaching the antenna to the vehicle and the base. A plurality of recesses are provided corresponding to the mounting angles of the bracket for regulating mutual angular displacement of the base within substantially the same range, and the convex portion is selectively engaged with one of the plurality of recesses. Since the base is fixed to the bracket with screws, the movable range of the antenna corresponding to the vehicle can be made substantially constant regardless of the mounting angle of the bracket.

Therefore, even when the screwing force decreases, the mutual angular displacement between the bracket and the base can be reduced, preventing the antenna from falling down, thereby preventing damage to the antenna, and preventing damage to the mounting member such as the gutter of a vehicle. Even if the mounting angle of the bracket changes depending on the shape of the bracket, by selectively engaging the convex part with one of the multiple concave parts, the antenna can be mounted at a safe desired angle, improving versatility. can be done.
