Description

[Detailed Description of the Invention] The present invention is a bar antenna mounting device for attaching a bar antenna to the outer casing of various receiving devices such as tuners and receivers. It relates to a structure that can be separated and rotated freely.

As a conventional bar antenna mounting device of this type, there is a device as shown in FIG. 1, for example.

This is an antenna case 2 that holds a bar antenna 1,
A holder 4 whose one end is rotatably attached to the antenna case 2 via a fulcrum pin 3; and a mounting body whose other end is rotatably attached to the holder 4 via a fulcrum pin 5. 6 and 3
The mounting body 6 is configured to be screwed to an outer casing (for example, a jack plate) 8 of a receiving device such as a Chukyu receiver using screws 7.

With this structure, the bar antenna 1 can be freely rotated around the pair of fulcrum pins 3 and 5, so when transporting the bar antenna 1 in packaging, for example, the bar antenna 1 can be attached to the outer casing 8 as shown by the chain line. By bringing them close together, the packaging volume is minimized, and the bar antenna 1 is prevented from being damaged by external force during transportation.

- When working or working, the bar antenna 1 can be raised by hand as shown by the solid line and moved freely to the best reception position of radio waves, which is very convenient.

However, the conventional device with the above structure is composed of three parts, resulting in high processing and assembly costs.

Since the bar antenna cannot be locked in a state close to the outer casing 8, this is inconvenient when packing.

The screws 7 must be used for attachment to the outer casing 8, which is inconvenient.

The present invention was devised to correct the above-mentioned deficiencies; it has a minimum number of parts, the bar antenna can be temporarily fixed close to the outer casing, and the bar antenna can be attached to the outer casing easily. We also try to provide something that is simple.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.

First, this bar antenna mounting device includes a holding part 12 that holds the bar antenna 11, a pivot part 13, a hinge part 14 that rotatably connects the holding part 12 and the pivot part 13, and the holding part 12. It is composed of a locking part 15 that is integrally molded.

These parts 12 to 15 are integrally molded from elastic synthetic resin such as nylon or polypropylene to form a single component.

By the way, the holding part 12 is composed of a cylindrical part 17 and a support part 18 at right angle S to the cylindrical part 17, and the bar antenna 11 is inserted through the cylindrical part 17 and held therein.

The pivot portion 13 has an S-shaped 5-shape in cross section, and is configured such that the pair of opposing pieces 20 can be bent in a direction toward each other against elasticity. ing.

Further, a pair of fulcrum pins 21 are integrally formed on the outside of the pair of opposing pieces 20 so as to be coaxial with each other.

Further, the hinge portion 14 is constituted by a thin structure portion that integrally connects a corner portion of the support portion 18 and the pivot joint portion 13 with each other, and the holding portion 1
2 is configured to be freely rotatable with respect to the pivot portion 13 within an angular range of S゛90°.

Note that the direction of the rotational force at this time is a direction perpendicular to the direction of rotation about the two fulcrum pins 21.

The locking portion 15 is composed of a pair of elastic claws 23, and a pair of slopes 24, 25 with opposite slopes are provided on the outside of the winter melon 23.

On the other hand, an insertion hole 28 for the pivot portion 13 is provided in an outer casing (for example, a jack plate) 27 of various receiving devices such as a tuner and a receiver to which the bar antenna 1 is to be attached.

A pair of folding pieces 29 are formed at both upper and lower edges of the insertion hole 28 by, for example, drawing, and a pair of upper and lower pin insertion holes 3 are formed between these folding pieces 29 and the outer casing 27.
0 are formed on the same axis.

Further, the insertion hole 28 is positioned directly above S, and the locking hole 31 of the locking portion 15 is formed in the outer casing 27.

Therefore, when attaching the bar antenna 11 to the outer casing 27, first push and bend the pair of opposing pieces 20 of the pivoting part 13 in a direction toward each other against elasticity, and then insert them into the insertion hole 28. Insert it as shown in the chain line in Figure 3 and release the above pressing and bending.

Then, the pair of opposing pieces 20 elastically return to their original state,
The pair of fulcrum pins 21 are inserted into the pair of pin insertion holes 30 and locked.

Therefore, the above installation can be done with one touch.

Next, for example, during packaging and transportation, the holding part 12 is rotated upward to S900 around the hinge part 14 as shown in FIG. 3, and the locking part 15 is locked in the locking hole 31.

Note that when the locking portion 15 is pushed into the locking hole 31 at this time, the pair of claws 23 are guided by these slopes 24 and are pushed in a direction toward each other against the elasticity, so that the locking portion 15 is pushed into the locking hole 31. It is inserted and locked inside.

Therefore, the above-mentioned locking is also a one-touch operation.

By the above-mentioned locking, the bar antenna 11 is temporarily fixed in a stable manner in a state close to the outer casing 27.

Next, during use, the locking portion 15 is pulled out from the locking hole 31.

At this time, if you pull the locking part 15 to the right in Fig. 3,
The pair of pawls 23 are guided by these slopes 25, pressed and bent toward each other against elasticity, and pulled out from the locking hole 31.

Therefore, the above-mentioned pulling out is also a one-touch operation.

After that, when the holding part 12 is rotated downward by S90° around the hinge part 14, the holding part 12 is
When the support section 18 is in the horizontal state, the end surface 18a of the support support section 18 comes into contact with the side surface 13a of the pivot portion 13, and the bar antenna 11 is supported in the horizontal state.

In this state, the bar antenna 11 is sufficiently spaced apart from the outer casing 27.

If the reception condition of radio waves is not favorable in this state, the bar antenna 11 is rotated around the pair of fulcrum pins 21 as shown in FIG. 5, and the bar antenna 11 is freely moved to the best reception position. let

Although the embodiments of the present invention have been described above, the holding portion, pivot portion, hinge portion, and locking portion referred to in the present invention are not limited to those shown in the drawings, and may include various other effective structures. It can be changed to

As mentioned above, the present invention allows the bar antenna to be brought close to the outer casing of the device during packaging and transportation, and also allows the bar antenna to be sufficiently spaced from the outer casing during use, and allows the best reception position of radio waves to be determined by rotation. A bar antenna mounting device that can be freely installed includes a holding part that holds the bar antenna, and a pivot joint that is detachable from the outer casing of the device and can be rotated depending on the mounting state. A hinge part that rotatably connects the holding part and the pivot joint part, and a locking part that temporarily fastens the holding part to the outer casing are integrally molded from synthetic resin. The pivot joint part is rotatably attached to the outer casing while the bar antenna is held in the holding part, and this installation is performed with the holding part held at the center of the hinge part. The structure is configured such that the bar antenna can be brought close to or separated from the outer casing by rotating with respect to the pivoting part. The bar antenna mounting device is configured such that the bar antenna can be temporarily fixed to the outer casing using the locking portion that is integrally formed therewith.

Therefore, the bar antenna mounting device of the present invention is composed of a single part integrally molded from synthetic resin, and can be molded in only one molding process, and can be assembled after molding. Since it is not necessary at all, it is extremely simple to manufacture and can be obtained at a very low cost.

Furthermore, since the bar antenna can be temporarily fixed in a state close to the outer casing, it is very convenient, for example, when packing.

Another advantage is that it is very easy to attach the bar antenna to the outer casing.
