3 (a) is a front view of an antenna mounting support fitting showing another embodiment of the present invention, FIG. 3 (b) is a bottom view showing a state where the projecting piece is fitted in the hole, and FIG. It is a figure showing a part of side view showing the state where the projecting piece is fitted in the hole, and FIG. 4 is a mounting bracket for an antenna when the attached fixture is applied to a handrail with an elliptical cross section. FIG.

Reference numeral 1 shown in FIGS. 1 and 2 designates a mounting bracket for an antenna, which is composed of a pair of holding bodies 2 and 3. One holding body 2 has a hole 2a at one end and the other holding body 3 is provided. A projecting piece 3a that fits into the hole 2a is formed on one end side of the.
A nut 2b that engages with a screw 4 is integrally formed on the other end of the holding body 2 to form a screw member, and a hole 3b for inserting the screw 4 is formed on the other end of the holding body 3. There is.

The antenna 5 is attached to the top of the holding body 2 so that the direction can be changed in three axial directions. That is,
A screw 6 extending in the y-y direction via an L-shaped bracket 6.
The antenna 5 is attached by a screw 7a extending in the xx direction via the a- and T-shaped brackets 7 and a screw 8a extending in the z-axis direction via the brackets 8.

When the screw 4 is screwed into the nut 2b through the hole 3b and tightened up, the other end sides of the two holding bodies 2 and 3 come close to each other and hold the head portion 9a of the handrail 9 having a U-shaped cross section. Since the two gripping bodies 2 and 3 are connected to each other between the columns 9b of the handrail 9 by the hole 2a and the projecting piece 3a formed at one end side thereof, the screw member side of the both gripping bodies is tightened. As it is raised, the two clamps 2 and 3 become stronger, and the head 9a of the handrail 9 becomes stronger.
If the screw member is loosened, the other ends of the two holding bodies 2 and 3 are separated from each other, and the tightening can be released.

As described above, when the head 9a of the handrail 9 is held by the two holding bodies 2 and 3, the holding body 2, the screw 4, and the other holding body 3 form a ring shape. Even if the tightening force of the screw member is lowered and loosens and the mounting bracket 1 itself falls off, it does not fall off the handrail 9.

The handrail head 9 is shown in FIG. 3 (a).
The cross-sectional shape of a'is a mounting support metal fitting for a circular shape (cylindrical body), and is slightly different from that of the head 9a having a U-shaped cross-section in the previous embodiment. The elastic pressing metal fittings 10 and 11 are detachably arranged on the handrail sides of the holding bodies 2 and 3 so that the head portion 9a ′ having a circular cross section can be equally and reliably held from the outside. Therefore, as the screw 4 is screwed in, the circular head portion 9a 'can receive the pressing force from the outer four locations substantially evenly by the left and right elastic pressing metal fittings 10 and 11, and the handrail portion 9a' is a cylindrical body. Even if it is, it can be surely gripped.

Next, referring to FIGS. 3B and 3C, the protruding piece 3
A state in which a is fitted in the hole 2a will be described. A plurality of holes 2a are formed on the bottom surface of the holding body 2, and the shape of the holes is a substantially convex hole in which a long side hole A and a short side hole B are connected.
On the other hand, the projecting piece 3a of the holding body 3 is configured such that the tip thereof is an enlarged portion C. The width t of the enlarged portion C is shorter than the length a of the long side hole A and longer than the length b of the short side hole B.

The method of fitting the protruding piece 3a into the hole 2a is as follows. First, the elastic pressing metal fittings 10 and 11 contact the head 9a 'through a plurality of holes in accordance with the width of the head 9a'. The optimum hole is selected so that both clamps 2 and 3 can be positioned. After that, the enlarged portion C of the projecting piece 3a is inserted into the long side hole A of the selected hole, and the projecting piece 3a is moved in the arrow p direction of FIG. 3B.

As described above, since the enlarged portion C is inserted from the long side hole A, the enlarged portion C is easily fitted, and when the enlarged portion C is moved in the arrow p direction, the enlarged portion C is less likely to be caught in the short side hole B and slip out. Therefore, it has a fitting structure that can be easily attached and detached and is unlikely to come off once fitted.

In the structure shown in FIG. 3, the antenna is not directly attached to the holding body 2 or 3, but is attached via the extension fitting 12. Therefore,
The extension metal fitting 12 is attached to the tip end portions of the sandwiching members 2 and 3 via the screws 13 and 14 at one end, and the other end can be turned in three axial directions as shown in FIG. 2 though not shown. The antenna is attached in this way. As described above, by using the extension metal fitting 12, it becomes possible to install the antenna at a position where the radio waves are more easily received.

In FIG. 4, the antenna mounting support metal fitting 1'of the present invention is applied to the handrail head 9a "having an elliptical cross-sectional shape, and the elastic pressing metal fittings 10 and 11 have cross-sectional shapes. Since it is substantially M-shaped, the one used for the handrail head 9a ′ having a circular cross-sectional shape in FIG. 3 can be applied as it is.

As described above, in the article mounting support fitting of the present invention, even if the screw member (screw 4 and nut 2b) is tightened, the holding bodies 2 and 3 are fitted and locked at one end. The two gripping bodies 2 and 3 are not separated from each other, and the tightening force effectively becomes the gripping force and the handrail 9 can be gripped.

Up to now, the embodiment of the present invention has been described with reference to the drawings as an object to be attached. However, the present invention is not limited to the antenna, and is firmly attached to an attached fixture.
