Abstract

<P>PROBLEM TO BE SOLVED: To surely regulate the movement of discs in a case regardless of the number of stored sheets of the discs, and to use the case also as a portable storing container. <P>SOLUTION: A supporting rod 3 the peripheral face of which has a screw part 3A in the up and down directions is erected at the central part of the upper face of a bottom plate 2 the upper face of which is covered freely openable/closeable by an outer case 1, and is equipped with a fixing nut 4 with a female screw to be screwed in the screw part 3A. Under a condition that the discs are placed and stored on the upper face of the bottom plate 2, when the fixing nut 4 is rotated so as to screw into the supporting rod 3, rotation of the fixing nut 4 is stopped at a position where the bottom face of the fixing nut 4 is brought into contact with the upper face of the uppermost disc. The movement of the discs is regulated by this contact. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a case in which a plurality of discs such as CDs and DVDs are stacked and stored, and more particularly, to a spindle case provided with a rod-like body (spindle) penetrating through a hole formed in a central portion of the disc.

  A number of discs such as CDs and DVDs used for recording document information, music information, image information, and the like are sometimes housed and transported in a case. For this reason, various cases have been proposed as housing cases. (For example, refer to Patent Document 1). On the other hand, blank discs on which no information is recorded are sold as a set of a predetermined number of, for example, 25 or 50, and stored in a predetermined case. As this case, a spindle case is generally used in which the spindle is positioned through a hole formed in the center of the disk.

  The spindle case includes a disc-shaped bottom plate having a diameter slightly larger than that of the disk, and a cylindrical or hollow frustoconical outer case that covers the top surface of the bottom plate so as to be freely opened and closed. The spindle extends upward from the center portion of the bottom plate, and when the outer case is put on the upper surface of the bottom plate, the screw portion formed on the upper end of the spindle is exposed to the upper surface side from the opening of the outer case. The bottom plate and the outer case are integrated by screwing a screw cap having a flange portion in contact with the upper surface of the outer case.

At this time, the protrusion extending downward from the inner upper surface of the outer plate comes into pressure contact with the uppermost surface of the plurality of discs stacked and accommodated in the case, and presses the plurality of discs downward. For this reason, in consideration of convenience when storing the disc in the case or taking out the disc from the case, the spindle is stored in the case even if the outer diameter of the spindle is sufficiently smaller than the inner diameter of the hole of the disc. The predetermined number of disks are not moved in the case by the action of vibration during transportation, and the predetermined number of disks can be stably stored in the case.

  However, in the conventional spindle case, the movement of the disk in the case is restricted by pressing the upper surface of the disk located at the uppermost position while the predetermined number of disks are stored in the case. If the number of discs stored in the disk is smaller than the predetermined number, the stored discs cannot be sufficiently pressed downward, and the movement of the discs in the case cannot be restricted.

  For this reason, if the case is moved in a state where a smaller number of discs are stored in the case, the disc may move in the case, and the disc may be damaged due to collision between the outer case and the discs. Therefore, there is a problem that the spindle case cannot be used as a portable storage container because it is not suitable for transportation in a state in which a smaller number of disks are stored. As a result, after the user purchases a predetermined number of disks stored in the spindle case, the spindle case is discarded as unnecessary, resulting in a waste of resources.

  The object of the present invention is to reliably restrict the movement of the disk in the case regardless of the number of stored disks, and can be used as a portable storage container, and is discarded after the purchase of the disk. It is an object of the present invention to provide a spindle case that can prevent waste of resources due to the above.

  The present invention has the following configuration as means for solving the above problems.

(1) A bottom plate in which a support rod penetrating a hole of a disk to be loaded and stored on the upper surface is extended upward from the center portion of the upper surface, and a hollow outer that covers the upper surface of the bottom plate so as to be freely opened and closed A case, and
A fixing member that is selectively fixed at an arbitrary position in the vertical direction of the support bar and that is larger than the hole of the disk in plan view is provided.

  In this configuration, the disc is stacked and accommodated on the upper surface of the bottom plate by passing a support rod extending upward from the center of the upper surface of the bottom plate through the hole of the disc. A fixing member having a shape larger than the hole of the disc is selectively fixed to the support bar at an arbitrary position in the vertical direction. Therefore, when the fixing member is moved downward from the upper end of the support bar after the disk is stored on the upper surface of the bottom plate, the fixing member comes into contact with the upper surface of the disk, and the fixing member is fixed to the support bar at this position. As a result, the movement of the disc is restricted.

(2) The support rod includes a vertical thread portion on a circumferential surface,
The fixing member is a fixing nut having an outer diameter larger than an inner diameter of the hole portion of the disc and screwed into a screw portion of the support rod.

  In this configuration, a fixing nut having an outer diameter larger than the inner diameter of the hole portion of the disk is screwed into a screw portion formed in the vertical direction on the peripheral surface of the support rod. Therefore, the fixing nut is selectively fixed at an arbitrary position in the vertical direction of the support bar by rotating the fixing screw screwed into the threaded portion of the support bar by a predetermined amount.

  According to the present invention, the following effects can be obtained.

  (1) After the disk is stored on the upper surface of the bottom plate, the fixing member is moved downward from the upper end of the support bar, and the fixing member that is in contact with the upper surface of the disk is fixed to the support bar. The movement of the disc in the case can be reliably regulated regardless of the number of stored discs. Accordingly, the spindle case of the present invention can be used as a portable storage container, and waste of resources can be prevented.

  (2) By rotating the fixing nut screwed into the threaded portion of the support bar by a predetermined amount, the fixing nut can be selectively fixed at an arbitrary position in the vertical direction of the support bar, and fixed to the upper surface of the disk. Regardless of the number of stored disks, the movement of the disk in the case can be reliably restricted by the contact of the nut. Accordingly, the spindle case of the present invention can be used as a portable storage container, and waste of resources can be prevented.

  FIG. 1 is an external view of a spindle case according to an embodiment of the present invention. FIG. 2 shows the internal structure of the spindle case. The spindle case 10 includes a hollow frustoconical outer case 1 and a disc-shaped bottom plate 2. A through hole 11 is formed in the upper surface of the outer case 1. The inner diameter of the outer case 1 is slightly larger than the outer diameter of the disk to be stored at the upper end, and increases in diameter toward the lower end 12.

  A step portion 21 is formed around the entire upper surface of the bottom plate 2, and the lower end portion 12 of the outer case 1 is fitted into the step portion 21 from above. A support bar 3 extends upward from the center of the upper surface of the bottom plate 2. The support bar 3 is a spindle in a conventional spindle case, and penetrates a hole of a disk to be stored.

  The support rod 3 has a cylindrical shape, and is formed by dividing a screw portion 3A in the vertical direction on the circumferential surface. The outer diameter including the screw portion 3A of the support bar 3 is made smaller than the inner diameter of the hole of the disk to be stored. A fixing nut 4 is screwed onto the support bar 3. Therefore, the fixing nut 4 is selectively fixed at an arbitrary position in the vertical direction of the support bar 3. The outer diameter of the fixing nut 4 is larger than the inner diameter of the hole of the disk to be stored.

The height of the support bar 3 is slightly lower than the height of the outer case 1. A through hole having an inner diameter larger than the outer diameter of the support rod 3 is formed at the center of the upper surface of the outer case 1, and a cap 5 passing through the through hole from the upper side of the outer case 1 is screwed together. The upper surface of the cap 5 is configured by a flange portion having an outer diameter larger than the inner diameter of the through hole. After the outer case 1 is placed on the upper surface of the bottom plate 2, the cap 5 is screwed onto the support rod 3. The flange portion of the cap 5 contacts the upper surface of the outer case 1, and the covering state of the upper surface of the bottom plate 2 by the outer case 1 is maintained.

In the spindle case 10 configured as described above, when the fixing nut 4 is removed from the support bar 3 with the outer case 1 removed from the bottom plate 2, the disk hole can be inserted into and removed from the support bar 3. Thus, the disk can be stacked and stored on the upper surface of the bottom plate 2, and the disk stored and stored on the upper surface of the bottom plate 2 can be taken out.

  When a predetermined number or less of discs that can be stored in the spindle case 10 are stacked and stored on the upper surface of the bottom plate 2, when the fixing nut 4 is screwed onto the support bar 3 and rotated, the bottom surface of the fixing nut 4 is moved. Abutting on the upper surface of the uppermost disk, the movement of the disk in the spindle case 10 is restricted. As a result, even if the spindle case 10 is moved in a state where a predetermined number or less of detectors are stored, the disk does not move in the spindle case 10 and the spindle case 10 can be used as a portable storage container. .

  In the above-described embodiment, the fixing member 4 of the present invention is configured by the fixing nut 4 that is screwed to the support rod 3 on which the screw portion 3A is formed. However, the fixing member is located at any position in the vertical direction of the support rod. Other configurations can be used provided that they are selectively fixed and have a shape larger than the hole of the disk in plan view. For example, a member that can selectively hold the peripheral surface of the support bar at an arbitrary position in the vertical direction of the support bar can be used as the fixing member.

1 is an external view of a spindle case according to an embodiment of the present invention. It is a figure which shows the internal structure of the said spindle case.
