[0002]

2. Description of the Related Art The applicant has previously disclosed a handle rotation support mechanism in Japanese Patent Application No. 1-84263. FIG. 8 is a main drawing attached to the specification. The handle rotation support mechanism disclosed in the specification includes a second posture standing forward of the operation surface A from a first posture (A) along an edge of the operation surface A with a side portion of the operation surface A as a fulcrum. (B), a handle 21 is provided between the handle 21 and the device main body 22. The handle 21 is positioned between the first position (a) and the second position.
When the elastic member 23 and the concave portion 21
a and 21b are fitted with the elastic lock mechanism for maintaining the posture thereof, and the operation surface A is provided with a push button 24 which operates linearly. When the push button 24 is pressed, the push button 24 is provided. A drive lever 25 is provided which is rotated by the lever 24 and rotates the handle 21 in the first posture (a) by a predetermined angle in the second posture (b).

In a handle rotation support mechanism of an electronic device having such a configuration, since the push button 24 operates linearly, the operation of the push button 24 is easy and the operation load is light. . Further, since the handle 21 is elastically locked in each posture, the handle 21 does not fall downward from the standing posture. Therefore, an effect can be obtained that the rotational load of the support portion of the handle 21 can be reduced as compared with the conventional case, and the pressing load by the push button 24 can be reduced as compared with the conventional case.

[0004]

The above-described effects can be obtained with the handle rotation support mechanism of the electronic apparatus. However, the drive lever 25 biases the vicinity of the support pin 26 of the handle 21 so that the drive lever 25 biases the vicinity of the support pin 26. Due to this, the handle 21 itself can be turned only by a small angle, and handling at the time of operating the handle is not easy, that is, since the amount of the handle 21 protruding forward when the push button is pressed is small, There is a disadvantage that it is difficult to grasp the handle.
In addition, since the drive lever 25 presses the handle 21 itself, the side of the handle 21 and the drive lever 25 must be arranged at an overlapping position. There is also a problem that the degree of freedom in designing the operation surface is restricted. Therefore, an object of the present invention is to provide a handle turning device for an electronic device in which the turning angle of the handle can be set to be large and the degree of freedom of design is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a partial side view of an electronic device mainly showing a handle rotation device as one embodiment, and FIG. 2 is an external perspective view of an electronic device equipped with the handle rotation device shown in FIG.
In this embodiment, an on-vehicle acoustic device will be described as an example of the electronic device.

In FIG. 2, reference numeral 1 denotes a main body chassis, and a nose 2 having an operation surface A is provided in front of the main body chassis. At the rear of the main body chassis 1, a connector 27 for connecting to a power supply unit, a speaker and the like in the vehicle is provided. The operation surface A is provided with a cassette insertion slot 3, a display unit 4, and various operation members 5a, 5b, 5c, 5d. Such an electronic device is designed so that it can be mounted not only on a car but also on a boat, a yacht, or the like, and the cassette insertion slot 3 can be covered with a cover 3a. The other various operation members 5a to 5d are also provided with waterproofing measures.

Reference numeral 6 denotes a handle. This handle 6
Is rotatably supported on the side surface of the nose 2 by a support pin 7, and a lock lever 8 is integrally formed at the intermediate portion. The lock lever 8 has a plate shape formed in an arc shape, and has a lock piece 8 at its release end.
a is integrally protruded. As shown in FIG. 1, the lock piece 8 a is provided with a first handle 6 along a lower edge of the nose 2.
Is inserted into the lock hole 9a of the base 9 to be mounted as a mounting member, whereby the main body chassis 1 is locked so as not to come off. A step 8b is formed on the outside of the lock lever 8 near the base end. One end of a drive lever 10, which will be described later, is locked to the step 8b.

The drive lever 10 is rotatably supported on the support pin 7 in addition to the handle 6. A bent piece 10 b is formed at one end 10 a of the drive lever 10, and the bent piece 10 b is engaged with a step 8 b formed on the lock lever 8. The other end 10c is in contact with a push button 12 provided on the operation surface A. The push button 12 is linearly slidably inserted in the direction of arrow B on the side of the operation surface A of the nose 2, and the operation of the push button 12 causes the drive lever 10 to rotate.

Next, the operation of the handle rotating device having the above-described configuration will be described with reference to FIGS. 1 and 2 and FIGS. 3 and 4. FIG. 1 shows a state in which the on-vehicle acoustic device is stored in the base 9 to be mounted. At this time, the handle 6 has rotated to the first posture (A) along the lower edge of the nose 2. In this position, the lock lever 8
The lock piece 8a at the open end is fitted into the lock hole 9a, and the on-vehicle audio device is locked in the base 9 to be mounted.

When the on-vehicle audio equipment is to be removed from the base 9 to be mounted, the push button 12 is pressed as shown in FIG. The push button 12 slides linearly in the nose 2 toward the left in the direction of arrow B. When the push button 12 is pressed, the drive lever 10 in contact with the push button 12 rotates counterclockwise about the support pin 7. Due to this rotation, the bent piece 10b formed at one end presses and biases the step 8b formed on the lock lever 8, whereby the lock lever 8 is moved together with the handle 6 around the support pin 7. Rotate counterclockwise. At this time, the lock piece 8a at the base end of the lock lever 8 comes out of the lock hole 9a, and the locked state is released.

At the position where the push button 12 is depressed most, as shown in FIG. 4, the handle 6 pivots greatly to the illustrated angle. Therefore, even if the user tries to raise the handle 6 by hand from this state, the operation can be performed extremely well, and the operability can be improved. When the handle 6 is manually lifted from this state, the handle 6 further rotates, and the handle 6 is substantially perpendicular to the operation surface A as described above. In this state, if the handle 6 is pulled as it is, the on-vehicle acoustic device is attached to the base 9.
Extracted from

If the steering wheel turning device is provided with a power transmission unit having the above-described structure , the steering wheel is not the handle itself as in the prior art.
Since the drive lever presses and biases the step formed on the outside of the lock lever, the length of the arm from the bent piece 10b to the support pin 7 is longer than the length of the arm from the push button 12 to the support pin 7. The length can be set large. Therefore, the position where the push button 12 is pressed most (the state of FIG. 4)
Can be set sufficiently large. Therefore, when the electronic device is pulled out from the mounting member, the handle 6 can be easily grasped, and operability can be improved. In addition, drive lever 1
Since the handle 6 is not directly biased at 0, it is not necessary to dispose the handle and the drive lever at overlapping positions. Therefore, it is possible to appropriately set the shape, size, and the like of the lock lever, thereby increasing the degree of freedom in design.

The present invention is not limited to the above embodiment, but can be variously modified within the scope of the invention. For example, when changing the turning angle of the handle when the push button is pressed most in the embodiment,
It is only necessary to appropriately set the angle formed by the arms at both ends of the drive lever that sandwich the support pin. Further, a plurality of steps formed on the lock lever may be formed to change the locking position of the bent piece. Even in this case, the same effect as in the above embodiment can be obtained, and the turning angle of the handle can be easily changed.
