DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device support mechanism provided with a spring (damper spring) for canceling a load of a device body on a damper.

[0002]

2. Description of the Related Art Generally, it is necessary to minimize external vibrations for precision equipment and equipment for reproducing a recording medium. For example, in recent years, a CD player that has rapidly spread has often skipped a recorded signal when vibration is applied from the outside during reproduction. Therefore, when a CD player is used for a vehicle with large vibration, a device supporting mechanism that supports the device main body to a vehicle-side supporting portion via a damper having a vibration absorbing force is employed. According to such a device support mechanism, even when external vibration is applied to the device main body, the damper absorbs the vibration. Therefore,
Even if a recording medium such as a CD is reproduced while the vehicle is running, vibration is not transmitted to the device main body, so that faithful reproduction is possible.
In addition, since the impact on the device is buffered, it is possible to contribute to protection of the device body and the recording medium.

In such a device support mechanism, a spring called a damper spring is provided between a device main body and a support portion for supporting the device main body. Each end of the damper spring is substantially engaged with the center of gravity and the support portion of the device main body, and cancels the load of the device main body on the damper. Therefore, the load of the device main body is prevented from being directly applied to the damper, and the deformation of the damper is suppressed. Further, the damper spring has a function of holding the damper at an appropriate position by its urging force. For this reason, it is possible to prevent a part of the damper from being fatigued and biasing the absorbing power to the vibration, and to always exert a uniform vibration absorbing power to the device body.

[0004]

By the way, in the case of a device having a large installation space limitation, such as a vehicle-mounted device, there are a vertical type and a horizontal type in a support portion for supporting the device main body. Therefore, the device main body accommodated in the support portion is installed corresponding to the type. However, the damper spring must always be vertically disposed in order to cancel the load of the device body on the damper. Therefore, when the installation direction of the support portion changes, it is necessary to change the installation direction of the damper spring accordingly. That is, the end of the damper spring engaged with the support is removed, the installation direction of the damper spring is changed, and the damper spring is engaged with the changed support.

[0005] In addition, such a replacement operation of the damper spring has been performed manually. However, it is very troublesome to manually remove and reattach the damper spring having a biasing force enough to cancel the load on the device body, and the working efficiency is poor.

The device support mechanism of the present invention has been proposed in order to solve the above-mentioned problems of the prior art. The purpose of the device support mechanism is to easily and easily adjust the damper spring according to the installation state of the device body. It is an object of the present invention to provide a device support mechanism that can change an installation angle and can absorb an impact on a device body.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an apparatus main body, a support section, and elastic support means for elastically supporting the apparatus main body with respect to the support section. In the device support mechanism for installing the device main body and its support portion at different predetermined angles, the elastic support means has one end rotatable with respect to one of the device main body or the support portion. And the other end is connected to the other of the device main body or the support portion, and a spring that resiliently supports the device main body by suspending the device main body substantially vertically,
Guide means for guiding the other end of the spring around the one end of the spring so as to be along the other of the device body or the support portion in accordance with a change in the installation angle of the device main body, wherein the guide means comprises: When guiding the other end of the spring, the other end of the spring is provided so as to be movable in a direction away from the one end and then in a direction approaching the one end again,
The predetermined angle is when the other end of the spring is closest to the one end, and the length of the spring at that time is substantially constant irrespective of the device installation angle of the device main body. .

The present invention having the above-described configuration has the following operations. That is, one end of a spring rotatably provided with respect to one of the device main body or the support portion is provided so that the spring supporting the device main body is vertical so as to correspond to a change in the installation angle of the device main body. Rotate as center. At this time, the other end of the spring connected to the other of the device main body or the support portion is moved along the other of the device main body or the support portion by the movement guide means while temporarily moving the other end in a direction away from the one end side. I will be guided. When the other end of the spring reaches a predetermined angular position, the other end of the spring is moved by the guide means in a direction approaching the one end again, and the spring is turned so as to hold the device main body at the installation angle. The moving position is fixed. The position where the other end of the spring is closest to the one end is the spring position corresponding to the predetermined position of the device, and the length of the spring at this time is substantially constant regardless of the device installation angle of the device main body. As described above, according to the present invention, the operation of simply rotating the spring without changing the spring holds the spring in a vertical state, and cancels the load of the device main body applied to the damper by the force of the spring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the device support mechanism of the present invention as described above will be specifically described with reference to the drawings.

FIGS. 1 and 2 are a side view and a front view, respectively, of an apparatus main body 1 supported by a vertical support. The device main body 1 is installed in a vertical direction, and dampers 3 for absorbing vibration are provided at both ends of both side edges 1a. The damper 3 is a pin 2a protruding toward the device body 1.
Through the damper plate 2. The damper plate 2 is provided on a support (not shown) and constitutes a part of the support. Further, the damper plate 2 has a fan-shaped opening 6 opened at 90 degrees in the center. A later-described damper link 5 is inserted through the opening 6, and contact portions 7, 7 with which the damper link 5 contacts are provided at both ends.

Further, a damper 3 and a damper plate 2
A damper spring 4 is provided in the gap perpendicular to the load direction. A base 4a of the damper spring 4 is provided with a hook 1b provided substantially at the center of gravity of the device body 1.
It is hung on. Further, the tip 4 b of the damper spring 4 is hung on the tip 5 b of the damper link 5. The damper spring 4 is set so as to cancel the load of the device main body 1 on the damper 3 and at the same time keep the damper 3 at an appropriate position with respect to the damper plate 2 at all times.

The damper link 5 is adapted to rotate around a base 5a provided outside the damper plate 2. The tip 5b of the damper link 5 that engages with the damper spring 4 is located inside the damper plate 2 through the opening 6 of the damper plate 2. Therefore, the tip 5 of the damper link 5
The rotation range of the damper link 5 is defined by the contact of b with the contact portions 7.

Further, since the tip portions 5b and 4b of the damper link 5 and the damper spring 4 are engaged with each other,
The damper spring 4 rotates in conjunction with the damper link 5. At this time, the base 5a, which is the rotation center axis of the damper link 5, is set to be shifted in the direction of the tip portions 5b, 4b from the base 4a, which is the rotation center axis of the damper spring 4. Therefore, the rotation stroke of the tip 5b of the damper link 5 is smaller than that of the tip 4b of the damper spring 4. Therefore, when the distal end portion 5b of the damper link 5 comes into contact with the contact portion 7, the urging force of the damper spring 4 is applied to the damper link 5 in the direction of the contact portion 7. That is,
The guide means in the present embodiment corresponds to a link provided so that the rotation shaft is biased, a contact portion for regulating the rotation position of the link, and a mounting position of the rotation shaft of the link and one end of the spring.

The operation of this embodiment having the above configuration is as follows.

That is, when the installation direction of the support portion is changed to change the vertically installed apparatus main body 1 shown in FIG. 1 to the horizontally installed one shown in FIG. 3, the damper link 5 is turned with the tip of a finger or a driver. Move. The damper spring 4 rotates in conjunction with the damper link 5. When the tip 5b of the damper link 5 comes into contact with the contact portion 7, the damper spring 4 is perpendicular to the device body 1.
At this time, the damper link 5 and the damper spring 4
The bases 5a, 4a, which are the respective rotation center axes of the damper springs 4, are shifted from each other.
Is applied in the direction of the contact portion 7 to be contacted, and urges the damper link 5 in the turning direction. Further, when the distal end portion 5b contacts the contact portion 7, the elastic force of the damper spring 4 is applied to the damper link 5, and the damper link 5 can be locked to the contact portion 7. As described above, according to the present embodiment, the device body 1 in which the installation angle is changed by approximately 90 degrees with the support simply by rotating the damper link 5.
It is possible to set the installation angle of the damper spring 4 vertically in accordance with the above. Therefore, it is possible to omit a replacement operation in which the tip portion 4b of the damper spring 4 is once removed from the support portion and then attached again.
Further, in this embodiment, the base portions 5a and 4a, which are the respective rotation center axes of the damper link 5 and the damper spring 4, are shifted, so that the damper link 5 is engaged at the contact portion 7 by utilizing the elastic force of the damper spring 4. Can be stopped.

The device support mechanism of the present invention is not limited to the above-described embodiment. In any of the above embodiments, the device support mechanism is provided on the damper plate. A link may be provided on any one of them. For example, a similar effect can be obtained even if a base of the link is provided at the center of gravity of the device main body and a damper spring is provided on the support portion side.

[0017]

As described above, according to the device supporting mechanism of the present invention, the installation angle of the spring with respect to the device main body can be very easily changed in accordance with the installation state of the device main body to absorb the impact on the device main body. It is possible to provide a device support mechanism that can perform the above-described operations. Specifically, according to the present invention, even if the installation direction of the support portion is changed, the other end of the spring is attached to the device main body by using the spring force of the spring by extremely simple means of rotating the spring. Alternatively, since it can be fixed to the other of the support portions, the work efficiency of changing the installation angle is improved. Also, at this time, the spring is temporarily expanded and then contracted during rotation, so that the installation position and direction of the spring corresponding to the predetermined position of the device main body are fixed by the spring itself, and the load of the device main body is reduced. Since it is offset by the resilience, it is possible to absorb the impact on the device body.
