[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a case for storing and storing disks used as recording media such as laser disks and video disks.

[0002]

[Prior Art]

 As a disc storage case, a hinged lid has been conventionally used to take out the stored disc or store the used disc. This type of disc case is composed of a lower lid 1 and an upper lid 2 as shown in FIG. 1, for example. A protrusion 3 is formed near the depth side end of the lower lid 1, and an engagement hole 4 fitted into the protrusion 3 is formed near the depth side end of the upper lid 2. Further, a locking projection 5 is provided on the middle portion of the side surface of the lower lid 1, and a locking recess 6 into which the locking projection 5 is fitted is formed inside the side surface of the upper lid 2.

A positioning member 7 is provided on the bottom surface of the central portion of the lower lid 1 in order to secure the accommodated disc A at a predetermined position in the case. The positioning member 7 is made of a synthetic resin and is formed into a substantially truncated cone shape, and is provided with elasticity by forming a plurality of cuts 7a along the radial direction. The diameter of the truncated cone is slightly larger than the diameter of the hole A ₁ provided in the central portion of the disk A to be accommodated in consideration of the diameter reduction due to elastic deformation.

Further, an appropriate rib 8 is formed on the inner side surface of the upper lid 2. The rib 8 improves the structural strength of the upper lid 2 and also has a function as a stopper when the disk A housed in the case tries to move for some reason. Further, the front side surface of the upper lid 2 is partially thinned to form a finger hook portion 9.

The upper lid 8 is attached to the lower lid 1 by fitting the protrusions 3 of the lower lid 1 into the engaging holes 4 with the side walls slightly opened. The attached upper lid 8 can be hingedly opened / closed around the protrusion 3. When the upper lid 2 is closed, the locking projections 5 are fitted into the locking recesses 6, so that the closed state is maintained.

[0006]

[Problems to be solved by the device]

 The case of this structure is often used as an effective one for protecting the housed disk A from contact with foreign matter, impact from the outside, and the like. However, since the case is thin, it is generally made of transparent synthetic resin, and a relatively large force is required to unlock the locking projections 5 and the locking recesses 6, the upper lid 2 is It is difficult to open. Further, since the disc A is fixed at the central portion, the periphery of the disc A may flicker and may be stored in the case in an unstable state.

Further, since it is designed on the assumption that the lower lid 1 is grasped by one hand and the upper lid 2 is opened and closed by the other hand, the size of the case is restricted. That is, when a case for accommodating a large-diameter disk is made in this form, the lower lid 1 cannot be gripped with one hand. Therefore, it is necessary to open and close the upper lid 2 while supporting the lower lid 1 in an extremely unstable state, which makes opening and closing more difficult.

The present invention was devised to solve such a problem, and by providing the upper lid slidably with respect to the lower lid, the opening / closing operation can be performed smoothly even if the size of the case becomes large. The purpose is to provide a disk storage case that is easy to use.

[0009]

[Means for Solving the Problems]

 In order to achieve the object, the disc storage case of the present invention is formed with a slide groove extending from substantially the center of each side wall standing on both sides of the bottom plate of the lower lid to the vicinity of the rear end on the depth side, and fitted into the slide groove. It is characterized in that the mating slide protrusions are projected inward from both side walls of the upper lid, and the lower lid and the upper lid are connected by fitting of the slide groove and the slide protrusions. A tongue that slides on the upper surface of the side wall of the lower lid is preferably provided on the side wall of the upper lid so as to project inward.

Further, in a disc storage case having a lower lid and an upper lid operably connected to the lower lid so as to be stored in a state in which the peripheral portion of the disc is constrained, it is formed on the bottom surface of the lower lid. A plurality of stoppers, each of which has a raised portion into which the central opening of the disc fits, are formed in the central portion of the disc storage space, and an eaves portion which restrains the periphery of the disc is formed in the peripheral portion of the disc storage space In addition, it is possible to provide a locking mechanism so that it can move back and forth around a part of the disk housing space. Here, in the lock mechanism, it is preferable that an eaves portion is formed on the end surface of the slider body facing the disk accommodation space.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 2, the disc storage case of the present invention has a structure in which the upper lid 50 is slid with respect to the lower lid 10 by a predetermined distance and then opened and closed. The lower lid and the upper lid 40 are integrally formed by injection molding. As the material of the lower lid 10 and the upper lid 40, it is preferable to use a transparent synthetic resin so that the accommodated disc can be seen from the outside.

The lower lid 10 is provided with a front wall 12, side walls 13, 14 and a rear wall 15 which stand upright on four sides of the bottom plate 11. The front wall 12 is formed with a step portion 16 as shown in FIG. Further, on the inner side of the front wall 12, raised portions 12a, 12a with which the positioning ribs 59, 59 of the upper lid 40 abut in the closed state are provided.

The side walls 13 and 14 are high on the front side and low on the depth side. Then, a hemispherical engaging protrusion 17 is formed on the high side wall portion on the front side. The side wall portion on the depth side has thick portions 18 having a large thickness from the middle. The thick portions 18, 18 are formed with slide grooves 19, 19 extending in the depth direction. The rear ends of the side walls 13 and 14 are formed as rounded portions 20 protruding from the rear wall 15.

On the bottom plate 11, a plurality of stoppers 21 to 27 are provided upright at positions corresponding to the size of the disc to be stored. The stoppers 21 to 27 can be appropriately supported by the reinforcing ribs 28 and 29 extending from the side walls 13 and 14 or the rear wall 15. The internal space surrounded by the stoppers 21 to 27 becomes the disc accommodation space B. At the center of the disc storage space B, a raised portion C is formed which is loosely fitted in the center opening of the disc to be housed.

The stoppers 21 to 27 are formed in an L-shaped cross section, and the low side portions 21 a to 27 a can be slightly raised from the surface of the bottom plate 11. The bottom portions 21a to 27a prevent the main surface of the disk arranged in the disk accommodation space B from directly contacting the surface of the bottom plate 11. Then, the L-shaped standing portions 21b to 27b become the portions that come into contact with the peripheral edge of the disk to be stored.

A lock mechanism 30 is provided in the peripheral portion facing the disc storage space B. As shown in FIG. 4, the locking mechanism 30 has a pair of engaging walls 31 and 31 which are erected from the bottom plate 11 and have a substantially inverted L-shaped cross section. Protruding portions 32, 33 that project laterally are provided in the middle portions of the engaging walls 31, 31, and the inside of each is an engaging groove portion 32a, 33a extending vertically upward from the bottom plate 11. .. Further, in FIG. 4, stop walls 34, 34 are provided at the rear ends of the engagement walls 31, 31.

A locking slider 40 is slidably provided between the engagement walls 31, 31. On the upper surface of the main body 41 of the locking slider 40, there is provided a finger hanging depression 42 extending in a direction perpendicular to the locking direction indicated by the arrow. A plurality of grooved grooves 43 extending in the same direction are formed on the upper surface of the slider main body 41 to prevent the sliding of the fingertip when the slider 40 is moved in the locking direction or the opposite direction.

In FIG. 4, an eaves portion 44 is provided on the front surface side of the slider body 41. The eaves portion 44 restrains the periphery of the disk and prevents the disk from rising when the disk is placed in the disk housing space B and the slider body 41 is moved in the arrow direction.

Engaging arms 45, 45 are provided on the side of the slider body 41 so as to project therefrom. The engagement arms 45, 45 are thinly formed and have a predetermined elasticity. The engaging arms 45, 45 are bent in the middle to form engaging portions 46, 46 which fit into the groove portions 32a, 33a inside the engaging walls 31, 31.

When the engaging portions 46, 46 are fitted in the unlocking protrusions 32, 32, the disc is accommodated in the disc accommodation space B or the accommodated disc is taken out from the disc accommodation space B. You are ready to At this time, since the rear wall of the slider body 41 is in contact with the inner surfaces of the stop walls 34, 34, the slider body 41 does not move further in the direction opposite to the arrow.

To lock, the fingertip is applied to the finger-holding depression 42 from this state, and force is applied to the rider body 41 in the arrow direction. When the applied force becomes larger than the elastic force of the engagement arms 45, 45, the engagement arms 45, 45 are elastically deformed and the engagement state of the engagement portion 46 with the unlocking groove portion 32a is released. Then, the slider body 41 moves in the direction indicated by the arrow.

When the slider body 41 moves forward by a predetermined distance, the engaging portion 46 fits into the lock groove portion 33a. At this time, the front wall 47 of the slider main body 41 is positioned at the peripheral edge of the disk accommodating space B, and the relative positions of the engaging walls 31, 31 and the locking slider 40 are set so that the eaves portion 44 faces slightly inward from the peripheral edge. It is set.

Eaves 24c and 26c are preferably formed on the stoppers 24 and 25 located on the opposite side of the lock mechanism 30 with the disc housing space B interposed therebetween. These eaves portions 24c and 26c, together with the eaves portion 44 of the slider body 41, prevent the accommodated disc from floating from the disc accommodating space B and rattling inside the case.

As shown in FIG. 5, the upper lid 50 includes side walls 52 and 53 standing upright on three sides of a top plate 51 and a rear wall 54. Slide protrusions 55, 55 fitted into the slide groove 19 of the lower lid 10 project inwardly on the side walls 52, 53. When the protrusions 55 and 55 are fitted in the slide groove 19, the upper lid 50 is slidably attached to the lower lid 10. Further, a pair of front and rear tongues 56 and 57 protruding inward are provided inside the side walls 52 and 53, respectively. These tongues 56 and 57 slide on the upper surfaces of the side walls 13 and 14 of the lower lid 10 and make the slide of the upper lid 50 relative to the lower lid 10 smooth.

Engagement holes 58, 58 to be fitted into the engagement protrusions 17, 17 formed on the side walls 13, 14 of the lower lid 10 are formed near the front end portions of the side walls 52, 53. When the engagement holes 58, 58 are fitted into the engagement protrusions 17, 17, the lower lid 10 and the upper lid 50 are held in a closed state. At this time, the positioning ribs 59, 59 provided near the front end of the upper lid 50 come into contact with the raised portions 12a, 12a provided inside the front wall 12 of the lower lid 10. Further, engagement holes 58 'and 58' that fit into the engagement protrusions 17 and 17 are formed in the vicinity of the depth side ends of the side walls 52 and 53, respectively. These engaging holes 58 ', 58' are fitted to the engaging convex portions 17, 17 of the lower lid 10 when the case is completely opened, and prevent rattling in the open state.

The rear wall 54 is lower than the side walls 52 and 53, and matches the height of the tongues 57 and 56. As a result, when the upper lid 50 is inverted and moved to the lower side of the lower lid 10 and completely moved to the open position, the lower lid 10 is supported by the tongues 57, 56 and the surface of the rear wall 54. An outer surface (back surface in FIG. 5) of the upper lid 50 is provided with an uneven portion 60 for finger hanging. The uneven portion 60 also serves as a mark indicating in which direction the upper lid 50 can be moved to open the case.

Next, the handling of this disc storage case will be described. When the case is completely closed, the upper lid 50 has the positional relationship shown in FIG. 6 with respect to the lower lid 10. That is, the slide protrusion 55 is located at the front end of the slide groove 19, and the engagement hole 58 is fitted in the engagement protrusion 17. At this time, the front surface and the rear surface of the lower lid 10 and the upper lid 50 coincide with each other, and are a flat box body as a whole.

When opening the case, first, a fingertip is pressed against the uneven portion 60 on the upper surface of the upper lid 50, and the upper lid 50 is slid with respect to the lower lid 10 as shown in FIG. At this time, the slide projection 55 fits into the slide groove 19 and the tongues 56 and 57 slide on the upper surfaces of the side walls 13 and 14, so that the upper lid 50 is moved with a slight force.

When the slide protrusion 55 reaches the rear end of the slide groove 19 by the movement of the upper lid 50, the movement of the upper lid 50 with respect to the lower lid 10 is restricted. At this time, the upper lid 50 is connected to the lower lid 10 only by fitting the slide protrusions 55 in the slide grooves 19, and the right side portion of the upper lid 50 is in a free state in FIG. 7. Therefore, the force to move the upper lid 50 to the right acts as a force to rotate the upper lid 50 around the sliding protrusion 55 as shown in FIG. Further, since the rounded portion 20 is formed at the depth-side end of the side walls 13 and 14, the upper lid 50 rotates smoothly without being caught by the corners of the side walls 13 and 14 of the lower lid 10.

The rotation of the upper lid 50 is stopped when the tongue piece 57 contacts the lower surface of the bottom plate 11. As a result, the upper lid 50 is inverted about the slide protrusion 55. Then, the inverted upper lid 50 is moved in the arrow direction shown in FIG. Also in this case, since the end surfaces of the tongues 56 and 57 and the rear wall 54 slide on the bottom surface of the lower lid 10, the upper lid 50 slides smoothly while maintaining the horizontal posture of the lower lid 10.

The leftward movement of the upper lid 50 is stopped when the slide protrusion 55 reaches the front end of the slide groove 19. Therefore, if the distance from the slide protrusion 55 to the rear wall 54 is made equal to the distance from the front end of the slide groove 19 to the front wall 12, the inverted upper lid 50 will be in the completely open position as shown in FIG. And overlaps the lower lid 10.

At the completely open position, the lock mechanism 30 described above is released, the disc is taken out from the disc accommodating space B, and operations such as reproduction are performed. Alternatively, a used disk is stored in the empty disk storage space B. At the time of storage, the opening formed in the center of the disc is fitted into the raised portion C. Then, the lock mechanism 30 is operated to sandwich the periphery of the stored disc between the eaves 24c, 26c, 44 and the bottom plate 11. In this way, since the disk is stored while being constrained around the disk, the storage posture can be reliably maintained even in a large-diameter disk.

Next, the upper lid 50 is moved in the reverse procedure, that is, the procedure from FIG. 10 to FIG. 6, and the case is closed. Also in this case, the force for moving the upper lid 50 to the right in FIG. 9 acts as a force for rotating the upper lid 50 around the slide protrusion 55 when the slide protrusion 55 reaches the end of the slide groove 19 on the depth side. To do. Then, when the upper lid 50 is moved to the left in FIG. 7, the positioning rib 59 comes into contact with the noble grain portion 12a, and the engaging holes 58, 58 are fitted into the engaging convex portions 17, 17, as shown in FIG. It will be closed.

In the above description, the disk is taken out or accommodated at the completely opened position in FIG. However, the present invention is not restricted to this, and it goes without saying that the disk can be taken out or accommodated in the half-opened state.

[0035]

[Effect of the device]

 As described above, according to the present invention, since the case can be opened and closed by a simple operation, no discomfort is felt when the disk is taken out or stored. In addition, since the direction in which the top lid is moved can be clearly identified and the top lid can be moved with a slight force, the case can be used for a long period of time without exerting an unreasonable force. Since the opening / closing operation is easy as described above, it is particularly suitable as a case for storing a large-diameter disk.

Further, when adopting a method of storing the disk by restraining the peripheral portion of the disk, it is possible to reliably hold the disk at the storage position even for a large-diameter disk. Further, in the storage state, the peripheral portion of the disc does not flutter due to an external impact, etc., so that the disc is prevented from being damaged during storage.
