BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

In this embodiment, as shown in FIG. 1, the locking structure of the present application is applied to a portable device (transceiver) T and a belt clip 1.

As shown in FIGS. 2 (a) and 2 (b), the locking structure includes the protrusion 2 provided on the transceiver T and the protrusion 2 shown in FIG.
As shown in (a) and (b), it is composed of a holder portion 10 provided on the belt clip 1.

The protrusion 2 is formed by forming a locking collar 4 around the tip of the shaft a provided with an engaging recess 3 and providing a second recess 11 in the collar 4. , The second recess 1
1 is formed in a U-shaped gentle taper shape.
Further, the same step 12 as that of the recess 11 is provided on the outer peripheral portion of the flange 4 except for the second recess 11 and the step 1 is formed.
2 and the second concave portion 11 are connected by providing a taper 13. Further, the concave portion 3 at the tip of the shaft a has a concave portion 3
A projecting portion 14 (both sides are tapered) toward the center of the second concave portion 11 is provided at a position opposite to the second concave portion 11.

In the case of this form, the protrusion 2 is shown in FIG.
As shown in (b), the transceiver T
Is attached to.

On the other hand, the holder portion 10 is shown in FIG.
As shown in (b), a C-shaped member is formed by using one clip of a resin-made belt clip 1 biased by a spring, and one end of the formed C-shaped member is opened so that the protrusion 5 is formed.
An opening 7 for inserting the is provided, and the projection 5 inserted from the opening 7 is slid along the groove 8. Further, a protrusion 9 for locking is provided inside the holder portion 10 facing the groove 8, and the protrusion 9 is adapted to fit in the recess 3 of the inserted protrusion 5. . At this time, by forming the upper part of the protrusion 9 in a tapered shape as shown in FIG. 3B, the recess 3 of the protrusion 5 can be easily fitted and difficult to be removed. A second projection 15 is provided below the projection 9, and the second projection 15 is provided.
Is provided at a position that fits into the second recess 11 of the inserted projection 5. At this time, the second protrusion 15 is provided with a taper on the left and right sides so that it can be easily attached to and detached from the second recess 11 as will be described later.

Further, the holder portion 10 has a first U-shaped notch 16 provided so as to pass between the protrusion 9 and the second protrusion 15 from the opening 7 side of the holder portion 10. A second U-shaped notch 17 is provided outside the first U-shaped notch 16 and formed so as to pass through the outside of the second protrusion 15. By providing such tongue-shaped notches 16 and 17, elasticity is exhibited.

Further, ribs 18 are formed along the groove 8 on both inner sides of the groove 8 of the holder portion 10. The rib 18 is provided to support the inserted projection 5 by line contact, and the projection 5 supported by the rib 18 can be smoothly slid and rotated.

This embodiment is configured as described above, and the belt clip 1 is sandwiched and attached to the belt B with the holder portion 10 facing outside, as shown in FIG. The protrusion 5 of the transceiver T is inserted through the opening 7 of the holder portion 10 attached to the belt B as shown in FIG.
At this time, the transceiver T does not need to be vertical as in FIG. This is because the tip of the protrusion 5 has a disk shape as the collar 4 so that the transceiver T can be inserted regardless of the orientation of the transceiver T.

Then, the protrusion 5 is slid along the groove 8 of the holder portion 10 (it can be easily slid by a rib), and the slid flange 4 comes into contact with the protrusion portion 9 of the holder portion 10 so that the protrusion portion 9 is formed. When pushed, as shown in FIG. 4B, the protrusion 9 is bent by the U-shaped first notch 16, and the bent protrusion 9 is shown in FIGS. 5A and 5B. Thus, it fits into the recess 3 of the protrusion 5.

As described above, by providing the first notch 16, it is possible to fit the protrusion 5 with an appropriate force without pressing the protrusion 5 with a strong force. Also, at this time,
Only one of the protrusions 9 fitted to the protrusions 5 is tapered, so that the protrusions 9 are easily fitted and are hard to come off, so that the protrusions 9 are not easily removed.

When the projection 5 is fitted into the projection 9 in this way,
Since the protrusion 5 is rotatably supported, for example, even when the transceiver T is not vertical as shown in FIG. 4A, it can be rotated to be vertical. In addition, when the transceiver T is made vertical in this way, the second recess 1 of the protrusion 5 is formed.
1 is the second part of the holder part 10 as shown in FIG.
Fit in the projection 15 of the. At this time, a step 12 is provided on the circumference of the protrusion 5, and is connected to the second concave portion 11 by a taper 13, and further, a second notch 17 formed in the holder portion 10.
As a result, the second protrusion 15 bends, so that the second recess 11 of the protrusion 5 easily fits into the second protrusion 15 of the holder 10.

With the second recess 11 and the second protrusion 15 engaged in this way, the transceiver T can be held in a locked state when walking, so that it can be easily handled without disturbing it. Has become.

On the other hand, when an unnecessary force is applied to the transceiver T when the user sits down, the second concave portion 11 is formed in a U-shaped taper so that the left and right second protruding portions are formed. Since the engagement with 15 is easily disengaged, the transceiver T is supported only by the protrusion 9 of the holder portion 10 by the protrusion 5, so that the transceiver T freely rotates and does not interfere. Further, when it is desired to stop the transceiver T again, the transceiver T may be set vertically. In this way, the transceiver T can be easily stopped or rotated with one touch.

For this reason, for example, even when the transceiver T having a poor left / right weight balance or the force of pulling by connecting a microphone to the transceiver T is applied, the antenna is prevented from inclining so that the antenna is always raised when necessary. The operability can be improved because it can be turned.

Next, the transceiver T can be easily removed from the belt clip 1. In this case,
As shown in FIG. 6A, when the transceiver T is rotated, as described above, the engagement between the second recess 11 of the protrusion 5 and the second protrusion 15 of the holder portion 10 is changed as shown in FIG. ) Is released. In this state, when the transceiver T is rotated as shown in FIG. 7A, as shown in FIGS. 7B and 7C, the second portion of the holder portion 10 separated from the second recess 11 of the protrusion 5 is removed. The protrusion 15 is located at the step 12 connected by the taper 13 and does not interfere with it. Therefore, FIG.
As shown in (a), when the transceiver T is rotated by 180 °, the protrusion 14 provided in the recess 3 of the protrusion 5 comes into contact with the protrusion 9 of the holder 10, and the protrusion 9 bends to cause the protrusion 1 to move.
4 is pushed up as shown by the arrow in FIG. for that reason,
The transceiver T is pushed up, and the engagement between the protrusion 5 and the protrusion 9 of the holder portion 10 is released.

In this way, the transceiver T is 180 °
Since it can be removed only by rotating it, it is not necessary to forcibly remove it by an extra force, and the belt clip 1 and the projection 5 are not broken.

When the transceiver T is removed, the protrusion 2 does not remain on the belt clip 1 so that it does not get in the way.

In the embodiment, the example in which the locking structure of the present application is applied to the transceiver T and the belt clip 1 is shown, but the invention is not limited to this, and can be used in a mobile phone and other mobile devices. Is.

In the embodiment, the projection 2 is screwed directly to the transceiver T, but the projection 2
May be as in the conventional example.
