Description

  The present invention relates to a storage structure for a disk-shaped recording medium for storing a large number of disk-shaped recording media such as CDs and DVDs, and more particularly, a storage member when the disk-shaped recording medium is not stored. And a storage structure for a disk-shaped recording medium that can be easily accommodated according to the number of disk-shaped recording media to be stored.

  Conventionally, in order to store a disc-shaped recording medium such as a CD or a DVD, a column (spindle) is erected in the center of the bottom plate, and a hole of the disc-shaped recording medium is inserted into the column, and this disc A spindle case is used in which a large number of recording media are stacked and an outer case is placed on the recording medium. In this type of spindle case, the number of disc-shaped recording media that can be stored is defined in advance, and the length of the support column to be erected is determined according to this number.

  However, when an arbitrary number of disc-shaped recording media are to be stored using the spindle case, an extra space is generated if the number is less than the specified number. In this case, the stored disk-shaped recording medium slides along the support, and the recording surface may be damaged by collision with the bottom plate or collision between the disk-shaped recording media. Further, even when storing and transporting a disc-shaped recording medium that is smaller than the specified number of sheets, the same space as when storing and transporting the specified number of sheets is required, which is inefficient.

In order to cope with such a problem, various types of spindle cases having different sizes are prepared and used depending on the number of disc-shaped recording media to be stored. However, according to this method, the above-mentioned drawbacks are surely solved, but it is necessary to prepare in advance various kinds of spindle cases corresponding to the number of stored sheets, which not only increases the cost, but also vast in inventory and transportation. Space is required.
Further, even if the disc-shaped recording medium is not stored, it cannot be disassembled, so that there is a problem that it is bulky, requires a large space for inventory and transportation, and has poor inventory and transportation efficiency.

  In order to solve these problems and accommodate an arbitrary number of disc-shaped recording media in one case, a bottom plate in which a support bar that penetrates a hole in the disk extends upward from the center of the upper surface, A hollow outer case that covers the top surface of the bottom plate so as to be openable and closable. The outer diameter of the support rod is a first diameter loosely fitted in the hole of the disk, and the peripheral edge of the hole of the disk There has been proposed a spindle case characterized in that it selectively changes to a second diameter in pressure contact with (Patent Document 1).

  Also, 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 central portion of the upper surface, and a hollow outer case that covers the upper surface of the bottom plate so as to be freely opened and closed And a holding member disposed on the outer peripheral surface of the disk stacked and stored on the upper surface of the bottom plate, up to the peripheral surface of the support bar in a plane parallel to the upper surface of the bottom plate. There has been proposed a spindle case characterized in that a holding member is provided that is displaceable between a retracted position and a contact position that is substantially equal in distance to the disc radius and the difference in radius of the hole. (Patent Document 2).

  Also. 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 central portion of the upper surface, and a hollow outer case that covers the upper surface of the bottom plate so as to be freely opened and closed, There is proposed a spindle case characterized in that a fixing member having a shape larger than the hole of the disk in a plan view is provided so as to be selectably fixed at an arbitrary position in the vertical direction of the support rod. (Patent Document 3).

According to these spindle cases, it is possible to prevent damage to the recording surface due to collision of the disk-shaped recording medium stored along the support column and collision with the bottom plate and disk-shaped recording media, And it is not necessary to prepare many kinds of spindle cases.
However, the inefficiency in storing and transporting disc-shaped recording media fewer than the prescribed number has not been improved. Further, the bulkiness when no disc-shaped recording medium is accommodated, and the poor inventory and transportation efficiency due to this are not improved at all.

  In view of such circumstances, the present invention, when not storing a disk-shaped recording medium, disassemble the storage member to reduce the inventory and transport space, increase the inventory and transport efficiency, and store the disk-shaped recording It is an object of the present invention to provide a storage structure for a disk-shaped recording medium that can be easily handled by simply changing the height of the support in accordance with the number of media, and therefore can greatly increase inventory and transport efficiency.

  In the present invention according to claim 1 for solving the above-described problem, a support column is detachably engaged with the support column engaging portion of the two frames provided with a support column engaging portion at the inner surface side center, A disc-shaped recording medium storage structure is characterized in that a hole of the disc-shaped recording medium is inserted into the support column, and the two frames and the disc-shaped recording medium are encapsulated with a shrink film. .

  According to a second aspect of the present invention, there is provided a disc-shaped recording medium storage structure according to the first aspect, wherein the support is press-fitted into the support engaging portion.

  The invention according to claim 3 is characterized in that the disc-shaped recording medium storage structure according to claim 1 or 2 is provided with a disk-shaped recording medium take-out hole on the outer periphery of the frame. To do.

  According to a fourth aspect of the present invention, there is provided a disc-shaped recording medium storage structure according to any one of the first to third aspects, wherein a shrink film hooking portion projects from the outer surface of the frame. Is the content.

  The invention according to claim 5 is characterized in that the storage structure for a disc-shaped recording medium according to any one of claims 1 to 4 is provided with a stacking locking portion provided in the frame. To do.

  The disc-shaped recording medium storage structure of the present invention uses two frames of the same type, and inserts the disc-shaped recording medium into a strut that is detachably engaged between the two, and encloses it with a shrink film. Therefore, when the disc-shaped recording medium is not stored, disengaging the frame and the support column and disassembling significantly reduces the bulk, reduces the inventory and transport space, and reduces the inventory. And the efficiency of transportation is significantly improved.

  In addition, if the number of disc-shaped recording media to be stored is large, the support can be lengthened. Conversely, if the number is small, the support can be shortened. For example, 30, 50, and 100 sheets can be used. For this purpose, since only three types of struts having different lengths need to be prepared, a significant space saving can be realized as compared to the case of preparing three types of cases that occupy a large space like the conventional spindle case.

  More specifically, a normal pipe member is sufficient for the column used in the present invention, and it can be cut into an appropriate length as needed, so that an arbitrary number of disc-shaped recording media can be accommodated. Even in this case, it is not necessary to prepare struts having different lengths in advance, so that inventory and transportation efficiency can be further improved, and inventory management becomes easy.

  In the disc-shaped recording medium storage structure according to the second aspect of the present invention, since the support column is press-fitted into the support column engaging portion, the support column and the support column engaging portion are firmly coupled to each other, and the frame is used during storage operation, handling, and transportation. The body is not inadvertently detached from the support column, and the disc-shaped recording medium can be stored safely and easily.

  The storage structure for the disc-shaped recording medium of the invention according to claim 3 is provided with a disc-shaped recording medium take-out hole on the outer periphery of the frame, so that the disc-shaped recording medium can be lifted easily by inserting a finger through the take-out hole. It can be taken out from the frame.

  The storage structure for the disc-shaped recording medium of the invention according to claim 4 has the shrink film hooking portion protruding from the outer surface of the frame, so that the shrink film is hooked on the shrink film hooking portion and is being handled. The disc-shaped recording medium can be securely and safely stored without being unintentionally detached from the frame body during transportation or transportation.

  In the storage structure for the disk-shaped recording medium according to the fifth aspect of the present invention, since the stacking locking portion is provided in the frame body, it is possible to prevent a trouble that the upper storage structure is displaced or slides down during stacking. In addition, stacking during storage and storage in a cardboard box is facilitated.

  In the disc-shaped recording medium storage structure of the present invention, a support column is detachably engaged with the support column engaging portion of two frames having a support column engaging portion provided at the center on the inner surface side. The hole portion of the disk-shaped recording medium is inserted, and the two frames and the disk-shaped recording medium are covered with a shrink film.

  Although the shape of the frame in the present invention is not particularly limited, a shape close to a disc-shaped recording medium to be stored is preferable, and examples include a circular shape and a polygonal shape such as a hexagonal shape and an octagonal shape.

  As the material of the frame, any material having a certain level of rigidity such as metal, plastic, and wood can be used, but plastic is most preferable in terms of weight reduction and moldability. Specific examples include polyolefin resins such as polyethylene and polypropylene, polystyrene resins, vinyl chloride resins, polyamide resins, polyester resins, ABS resins, AS resins, and the like.

  Reinforcing ribs for reinforcing the frame can be provided on the outer surface side of the frame. By providing this reinforcing rib, the thickness of the frame can be reduced, the weight can be reduced, and the amount of material used can be reduced, which is economical.

  A column engaging portion is provided at the center on the inner surface side of the frame. For example, when the strut to be engaged is cylindrical, the strut engaging portion is provided in a convex shape so as to fit inside the cylinder, and when the strut is columnar (solid), It is provided in a concave shape so as to fit externally.

  In order to make it easy to take out the disc-shaped recording medium in the vicinity of the frame, the frame is preferably provided with an extraction hole. Such an extraction hole may be provided on the outer periphery of the frame body and may have a size that allows a finger to be inserted. At least one take-out hole is provided. However, providing a plurality of take-out holes is advantageous because a disc-shaped recording medium can be taken out from any take-out hole.

  The frame body is preferably provided with a shrink film latching portion protruding from the outer surface. The shrink film is hooked on this hooking portion and is prevented from shifting during handling or transportation. The shrink film hooking portion may be provided over the entire circumference of the frame body or may be provided partially.

  It is preferable to further provide a stacking locking portion on the frame. By providing the stacking locking portion, the trouble that the upper storage structure is displaced or slipped down during stacking can be prevented, and stacking during storage and storage in the cardboard box is facilitated.

  It is preferable that the two frames have the same shape. By doing so, manufacturing is facilitated, cost is reduced, and inventory management is facilitated.

Since the hole of the disk-shaped recording medium inserted through the support column in the present invention is usually circular, it is preferable that the column has a circular cross section.
The material of the support column is not particularly limited, and examples thereof include plastic as well as the frame material.

  The column is removably engaged with the column engaging part of the frame. Accordingly, at least the front end portion with which the strut is engaged depends on the shape of the strut engaging portion as described above. For example, if the strut engaging portion is convex, it is concave so as to fit outside, and if it is concave, it is convex. The shape. Therefore, the column is preferably a cylindrical body or a columnar body, and in particular, a cylindrical body is preferable in that the weight can be reduced.

  The column is preferably press-fitted into the column engaging portion of the frame. By press-fitting in this manner, the strut is firmly engaged with the strut engaging portion, and a work for inserting a disk-shaped recording medium into the strut or encapsulating with a shrink film is easy, and stable without wobbling. Can be obtained.

In the press-fitting, for example, a plurality of convex pieces are provided by providing a small gap inside the convex portion of the column engaging portion or the convex portion of the column, and on the other hand, the concave portion of the column engaging portion or the concave portion of the column to be fitted to this is provided. This can be easily done by inserting the convex piece into the concave portion while contracting and deforming the convex piece piece into a smaller diameter than the diameter of the convex portion of the column engaging portion or the convex portion of the column.
The inserted convex piece is stretched to return to its original state by the restoring force and elastic force due to elasticity, and the inner surface of the concave portion is elastically pressed, so that it is firmly bonded.
It is also possible to cut one or two screws and screw the struts to the strut engaging portions.

The length of the column is determined according to the number of disc-shaped recording media to be stored. For example, in order to apply to three types of stored numbers of 100 sheets, 50 sheets, and 30 sheets, three types of struts having different lengths may be prepared.
Furthermore, if necessary, a long support column can be prepared and cut according to the number of stored sheets to form a support column having a predetermined length. In this case, the struts can be cut at appropriate intervals so that they can be cut without a cutting tool such as a knife.

  In the storage structure of the present invention, one end of the support is normally detachably engaged with the support engaging part of one frame, the hole of the disc-shaped recording medium is inserted into the support, and the other end of the support is the other. The frame body is detachably engaged with the strut engaging portion of the frame body, and is further encapsulated in a shrink film. There is no restriction | limiting in particular as a shrink film, For example, the biodegradable shrink film which consists of polylactic acid etc. other than polyvinyl chloride, a polypropylene, polyethylene, etc. is illustrated.

  In the disc-shaped recording medium storage structure of the present invention as described above, since the frame and the support are detachably engaged, for example, before use (before recording medium storage) or after use (recording medium is taken out). The latter can be disassembled by releasing the engagement between the frame and the column. Therefore, it is not bulky and easy to handle, and does not require a large space for inventory and transportation. Good.

  In addition, by preparing only the struts having different lengths, it is possible to store a predetermined number of disc-shaped recording media, so that the number of stored sheets can be easily accommodated without requiring a large space for inventory or transportation. It is possible.

  Further, when the number of disc-shaped recording media is small and there is a possibility that the recording media may swing and be damaged, the support is cut to an appropriate length to solve the above problem. You can also.

  Hereinafter, the storage structure of the disk-shaped recording medium of the present invention will be described with reference to the drawings showing embodiments, but it is needless to say that the present invention is not limited to only the embodiments.

Example 1
1 is a schematic cross-sectional view of a disc-shaped recording medium storage structure according to the present invention, FIG. 2 is a plan view of a frame, FIG. 3 is a bottom view thereof, and FIG. 4 is a cross-sectional view taken along line AA in FIG. It is the schematic which shows the state which engages a support | pillar and inserts a disk-shaped recording medium in this support | pillar.

  As shown in FIG. 1, the disc-shaped recording medium storage structure 1 of this embodiment has a column 3 on the column engagement portion 2 a of two frames 2 provided with a column engagement portion 2 a at the center on the inner surface side. Are removably engaged, and a hole of a disc-shaped recording medium 4 is inserted into the support column 3, and these are encased in a shrink film 5.

  As shown in FIGS. 2 to 4, the frame 2 has a disc shape, and a support engaging portion 2 a for attaching the support 3 to the central portion on the inner surface side and a support portion 2 b of the disc-shaped recording medium 4 on the outer side. The reinforcing ribs 2c are provided concentrically and radially on the outer surface side. The outer peripheral reinforcing rib 2c extends to the inner surface side and serves to protect the disc-shaped recording medium 4 accommodated in the vicinity of the frame. On the other hand, the outer reinforcing rib 2c simultaneously covers the shrink film. It also serves as a stop 2d.

  As shown in FIGS. 1 and 4, one end of a cylindrical column 3 is inserted into the column coupling portion 2 a of the lower frame 2, and a predetermined number of disc-shaped recording medium 4 holes are inserted into the column 3. Then, the other end of the support column 3 is inserted into the support column engaging portion 2a of the upper frame 2 and is encapsulated with the shrink film 5 to form the storage structure of the present invention.

  In this embodiment, as described above, in the shrink film 5, the reinforcing rib 2c on the outer peripheral surface side of the frame body 2 serves as the shrink film retaining portion 2d, and the shrink film 5 is not prepared during handling or transportation. Troubles that cause misalignment are prevented.

In the disc-shaped recording medium storage structure 1, after removing the shrink film 5 and taking out the disc-shaped recording medium 4, the column 3 is pulled out from the column engaging portion 2 a of the frame 2, and the frame 2 and the column 3 are separated. Transported and stored in a disassembled state. Therefore, since a large space is not required for transportation and storage, transportation and storage efficiency can be improved.
In FIG. 1, a cushion material (such as polyurethane) having the same size as the support portion 2b is interposed between the disc-shaped recording medium support portion 2b and the disc-shaped recording medium 4 to protect the recording medium. Sometimes omitted.

Example 2
The disc-shaped recording medium storage structure 1 of the present embodiment is the same as that of the first embodiment except that the column 3 is press-fitted into the column coupling portion 2a as shown in FIGS.

  That is, in FIGS. 5A and 5B, the strut engaging portion 2a is formed with a plurality of (four in the figure) convex pieces via a small gap, and the upper peripheral portion of the convex piece is inclined outward. A descending taper portion 2e is provided.

  Thus, as shown in FIG. 5B, by pressing the cylindrical column 3 having a diameter smaller than that of the column engaging portion 2a along the tapered portion 2e, the convex piece is elastically shown by an arrow. Since it deforms toward the small gap and contracts by that amount, the column 3 can be press-fitted into the column engaging portion 2a, and once pressed, the contracted convex piece expands to return to the original state, and the column inner surface , So that the column 3 is firmly coupled to the column engaging portion 2a and does not come off carelessly.

  FIG. 6 is the same as the case of FIG. 5 except that the strut engaging portion 2a is two convex pieces with a small gap. In this case, the convex piece is not only deformed toward the inner small gap, but is also bent and deformed in the length direction of the convex piece.

  FIG. 7 shows an example in which the strut engaging portion 2a is composed of a plus (+) convex piece. In this case, the plus-shaped convex piece bends in the longitudinal direction and deforms to reduce the diameter, press-fit the support column 3, and once press-fit, the projecting piece expands to return to the original state. The inner surface is pressed to prevent the support column 3 from being inadvertently detached.

Example 3
The disc-shaped recording medium storage structure 1 of the present embodiment is the same as that of the first embodiment except that an extraction hole 2f of the disc-shaped recording medium 4 is provided on the outer periphery of the frame 2 as shown in FIG.
By providing the take-out hole 2f in this way, when taking out the disc-shaped recording medium 4 in the vicinity of the frame 2, the recording medium 4 can be easily taken out by inserting a finger into the take-out hole 2f.

Example 4
As shown in FIGS. 9 and 10, the disc-shaped recording medium storage structure 1 of the present embodiment is replaced with the column engagement portion 2 a of the frame 2, instead of the column coupling portion 2 a of the second embodiment (FIG. 5A, (B)) is adopted, four take-out holes 2f of the disk-shaped recording medium 4 are provided on the outer periphery (FIG. 9), and further, stacking latching portions 2g and balance legs 2h are provided on the outer surface ( FIG. 10) is the same as the first embodiment.

  That is, in the present embodiment, the stacking locking portion 2g divides the outer surface of the frame body 2 into approximately four equal parts, which are two opposed regions, which are inward by a width w from the shrink film hooking portion 2d. The balance leg portion 2h is provided in the other two opposite areas, that is, the area where the stacking locking portion 2g is not provided, and has an arc shape corresponding to the width w. It is provided in the region 2i.

  As shown in FIG. 10, the frame 2 is used as the upper frame 2 of the lower storage structure 1 and balanced with the stacking locking portion 2 g of the lower frame 2 of the upper storage structure 1 stacked on the frame 2. The leg portion 2h is indicated by a broken line, but one stacking locking portion 2g is in a region where the other stacking locking portion 2g does not exist, and one balancing leg portion 2h has the other width w. It becomes the shape fitted in the arcuate region 2i, and the trouble that the upper storage structure 1 is displaced from or slides down from the lower storage structure 1 is prevented.

  Further, the balance leg 2h literally serves to keep the storage structure in good balance. For example, when the storage structure of the present embodiment is placed on a flat table, when the balance leg 2h is not present, the shrink film hooking portion 2d and the shrinking film latching portion 2d Since the stacking locking portion 2g is protruded, the balance is bad, and the region where these are not present is depressed, so there is a risk of rattling in this direction. Such rattling is prevented.

  Needless to say, both the stacking locking portion 2g and the balance leg 2h function as reinforcing ribs. Further, the shrink film 5 can be encapsulated to the inner side of the balance leg 2h. In this case, the balance leg 2h, together with the shrink film hook 2d, also serves as the shrink film hook. It is.

Example 5
As shown in FIG. 11, the disc-shaped recording medium storage structure 1 of the present embodiment is substantially the same as that of the first embodiment except that the length of the support column 3 is approximately doubled and the number of disc-shaped recording media 4 is doubled. It is the same.
Thus, according to the disc-shaped recording medium storage structure of the present invention, the number of disc-shaped recording media 4 can be accommodated freely by simply changing the length of the column 3.

  In the above-described embodiment, the storage structure in which the frame body is positioned up and down has been described. A storage structure in which the frame is positioned up and down is preferable from the viewpoint of ease of storing the disc-shaped recording medium.

As described above, according to the disk-shaped recording medium storage structure of the present invention, when the disk-shaped recording medium is not stored, the storage member can be disassembled, so that the inventory and transport space can be greatly reduced.
In addition, any number of disc-shaped recording media can be stored simply by changing the length of the support column, which is easier than changing the size of the case itself, as in the case of a conventional spindle case. Even in the case of preparing a plurality of types according to the number of stored sheets in advance, the case itself and the support column have much smaller inventory and transport space, and storage and transport efficiency can be dramatically improved.
