Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disk case for housing a disk such as a digital audio disk.

[Conventional technology]

2. Description of the Related Art Conventionally, as a disk case for accommodating a digital audio disk, there is a structure as shown in FIGS. 2 and 3. In the figure, reference numeral 1 denotes a main body, and a concave portion approximately the same size as the disk 2 is provided approximately in the center thereof as a placing portion 3 on which the disk 2 is placed. Cutouts 4 are provided on the left and right sides of the mounting section 3 into which fingers can be inserted when attaching and detaching the disk 2. Further, a locking portion 5 that fits into the center hole 2a of the disk 2 and locks the disk 2 is provided approximately at the center of the mounting portion 3. The locking portion 5 is made of an elastic body, and has a protruding portion 5a that protrudes toward the outer circumference of the disk at its tip. Reference numeral 6 denotes a lid rotatably supported on the main body 1 about a fulcrum 7. Main body 1 and lid 6
is provided with a recess 8 and a protrusion 9 that engage with each other when the lid 6 is closed against the main body 1.

The effect will now be explained. When taking out the disc 2 from the disc case, press the lid 6 to release the engagement between the recess 8 and the protrusion 9, and rotate the lid 6 about the fulcrum 7 in a direction perpendicular to the flat surface of the disc 2. to open the lid 6 relative to the main body 1. Insert left and right fingers into the left and right notches 4 and lift the disk 2 upward. Since the locking portion 5 is made of an elastic body, it is elastically deformed and the disk 2 is released from the locking of the locking portion 5. Next disk 2
When storing the disc 2, grasp the left and right sides of the flat surface of the disc 2 with your fingers (or grip the outer circumference of the disc 2 with your left and right fingers), and fit the center hole 2a of the disc 2 into the locking part 5. Press down on disk 2. The locking part 5 is elastically deformed and inserted into the center hole 2a of the disk 2, and the protruding part 5a presses the disk 2 onto the main body 1 from the side wall and upper flat part of the center hole 2a.
to lock. After that, the lid 6 is rotated about the fulcrum 7, and the recess 8 and the protrusion 9 are elastically deformed and engaged. As a result, the lid 6 is closed.

[The problem that the idea attempts to solve]

However, such conventional disk cases,
Since the lid is configured to rotate in a direction perpendicular to the flat surface of the disk, it is impossible to open and close it with one hand, which is particularly inconvenient for a car driver to operate it at work. Another drawback was that multiple cases could not be used in stacks. Furthermore, since the disk is attached or detached by applying force near the outer circumference while the center hole is locked, there is a drawback that the disk is easily bent and warped.

The present invention was developed to solve these problems, and it prevents the disk from bending or warping, allows multiple disk cases to be stacked, and can hold the disk. To provide a disk case that can hold a holder in an open state and a closed state to facilitate operation.

[Means to solve the problem]

The disk case according to the present invention includes a main body having a flat surface parallel to the flat surface of the disk, and a main body supported by the main body so as to be rotatable in a direction parallel to the flat surface of the main body, and sandwiching the outer peripheral portion of the disk. a holder having a holding portion that can be held; a disk holding means rotatably supported by the holder in a direction parallel to the flat surface of the main body and resiliently holding the disk in a removable manner; The holder includes holder biasing means for biasing and holding the holder in a first position when the holder is pulled out from the main body, and a second position when the holder is rotated and stored in the main body.

Further, the holder biasing means includes a protrusion formed near a fulcrum of the holder, and a spring attached to the main body to bias the protrusion,
It is preferable that the holder is biased and held in one of the first and second positions depending on whether a straight line connecting the protrusion and the fulcrum is centered over the spring.

Further, it is preferable that the holding part of the holder is a groove part formed on the flat surface of the disk over an angle range slightly larger than 180 degrees from the center of the center hole.

[Function and Examples]

1 and 4 show the structure of a disk case according to an embodiment of the present invention. Reference numeral 11 denotes a main body made of plastic or the like, which has two plane parts 11 that are approximately parallel to the plane part of the disc 2 in the stored state.
a, and a side wall 11b that closes a part of the outer peripheral end of the flat portion 11a, and the portion that is not closed by the side wall 11b forms an opening 11c. 1
Reference numeral 2 designates a holder made of plastic or the like, which is rotatably supported on the main body 11 about a fulcrum 13 in a direction parallel to the plane portion 11a thereof, and is located at a position housed inside the main body 11. (Fig. 1a) and the pulled out position (Fig. 1b). The main body 11 is attached to the holder 12.
A side wall 12a is provided approximately corresponding to the opening 11c, and when the main body 11 is housed inside the main body 11, the side wall 12a approximately closes the opening 11c. Further, the holder 12 is provided with a groove portion 12b serving as a clamping portion at a position approximately corresponding to the outer periphery of the disk 2, so that the outer periphery of the disk 2 can be clamped. The groove portion 12b is formed on the flat portion 12c with a diameter of 180° centered on the center hole 12d.
It is formed over a range of angles slightly larger than degrees. The diameter of the center hole 12d is larger than the diameter of the center hole 2a of the disk 2. 12
e is a notch large enough to allow insertion of a finger. A spring 14 is attached to the main body 11 and biases the holder 12 near the protrusion 12f. This spring 14 and the protrusion 12f constitute a holder biasing means, and this holder biasing means pushes the holder 12 into the first position pulled out from the main body 11.
and a second position where the holder 12 is rotated and housed in the main body 11, respectively.
Reference numeral 15 denotes an arm constituting a disk holding means that elastically holds the disk 2 in a detachable manner, and is rotatably supported in a direction parallel to the flat surface of the main body about a fulcrum 16 on the holder 12. . Reference numeral 17 denotes an elastic piece (which may be a spring) constituting the disk holding means, and biases the arm 15 clockwise. Reference numeral 18 denotes a stopper for regulating the limit of rotation of the arm 15 in the clockwise direction. Arm 1
A groove 15a having the same structure as the groove 12b of the holder 12 is formed at the tip of the holder 12, and the groove 12b and the groove 15a are formed at the same height position with respect to the flat part 12c.

Next, the effect will be explained. When taking out the disk 2 from the disk case, the holder 12 is rotated clockwise in the state shown in FIG. 1a. At this time, the straight line connecting the protrusion 12f of the holder 12 and the fulcrum 13 makes an angle of 90 degrees or less with respect to the spring 14, so the holder 12 is moved counterclockwise (closed direction).
is energized by The holder 12 is rotated against the urging force of the spring 14, and the protrusion 12f and the fulcrum 1
The angle of the straight line connecting 3 with respect to the spring 14 is
If it exceeds 90 degrees (over center),
The spring 14 urges the holder 12 clockwise (release direction). Therefore, from now on, the holder 12 is rotated by the biasing force of the spring 14, and the locking portion 12 is rotated.
g comes into contact with the stopper 11d of the main body 11 and stops. In this position, the center hole 2a of the disk 2 is exposed to the outside of the main body 11. Therefore,
The center hole 2a and the outer periphery near the notch 12e can be grasped with one hand, and in that state, the disk 2
The disk 2 can be removed by pulling the disk 2 upward and to the left in the figure so that the outer peripheral portion of the disk 2 is removed from the grooves 12b and 15a. Furthermore, at this time,
Although the groove portion 12b is formed over 180 degrees, since it is made of an elastically deformable material, there is no problem in the removal operation (of course, it may be formed over a range of 180 degrees or less). Further, since the arm 15 biased by the elastic piece 17 can be rotated counterclockwise, there is no problem with the removal operation. After removing the disk 2, the arm 15 rotates a little further until it comes into contact with the stopper 18, and then stops there.

When storing the disk 2, hold the center hole 2a and the outer periphery of the disk 2 between your fingers, and insert and fit the outer periphery of the disk 2 into the grooves 12b and 15a. At this time, the holder 12 has a notch 12e and a center hole 12d having a larger diameter than the center hole 2a of the disk 2.
is provided, so there is little risk that fingers will become an obstacle to operation. Also, this allows the disk 2 to be placed in the holder 12.
It is supported without wobbling. Next, holder 1
2 is rotated counterclockwise against the biasing force of the spring 14. The angle of the straight line connecting the protrusion 12f and the fulcrum 13 with respect to the spring 14 is 90 degrees or more.
When the angle is less than 90 degrees, the spring 14 now urges the holder 12 counterclockwise. Therefore, holder 1
2 is accommodated in the main body 11 by the biasing force of the spring 14.

FIG. 5 shows another embodiment of the present invention, in which the main body 11
In contrast, this is a case in which the holder 12 is slidable in a direction parallel to the flat surface of the disk 2, and the other configurations are the same as those described above, so a detailed description thereof will be omitted.

As described above, in the present invention, the main body and the holder constitute a disk case, and the holder is provided with a means for urging the disk from a direction parallel to the flat surface, so that it is difficult for the disk to warp. Therefore, the disk does not wobble not only during opening/closing operations but also in the stored state, and there is little risk of damage to the disk. Furthermore, since the direction in which the holder is pulled out is parallel to the flat surface of the disk, it is possible to stack multiple disk cases and it is easy to operate, making it especially convenient when used inside a car. .

[Effect of idea]

As described above, the present invention is provided with a holder biasing means that biases and holds the holder in the first position where the holder is pulled out from the main body and the second position where the holder is rotated and stored in the main body. By doing this, the holder that holds the disk can be held still in the open state and the closed state, so the holder in the closed state will not spontaneously pop out due to vibrations of the car, and the holder in the open state will not be able to stand still. This has the effect that the operation of engaging and disengaging is extremely easy.
