[Technical field to which the invention belongs]

 According to the present invention, a stopper for the lid is provided in a portion that can be seen as an external appearance by incorporating a mechanism for determining the maximum opening of the lid in the bearing portion, which is an engagement portion between the lid and the main body, particularly for the storage box. In addition to eliminating the need to improve the appearance, it is possible to maintain a fully open state with sufficient margin even if articles are placed on the lid side when the lid is fully opened. Regarding storage boxes.

[Prior art]

 With the spread of information equipment and the accumulation of electronic data, various recording media such as magnetic disks and optical disks have come to be used in large quantities, and storage boxes have been used to organize these recording media and protect them from dust. It is common to store them in

[0003] There are various types of storage boxes having different shapes, storage methods, opening and closing mechanisms, etc. Among them, the one most commonly used is a main body and a lid. There is a storage box in which a recording medium is taken in and out by opening and closing around a bearing portion.

When using a storage box of this type, the storage box is placed on a flat desk or the like, and the lid is opened until the lid contacts the upper surface of the desk. It is common to see that possible compact discs (CDRs) are first leaned on the lid, then used one after the other, and then transferred to the main unit one after the other, and then closed when all the components have been transferred to the main unit. Can be

However, it is necessary to move the storage box when the CDR is still left on the lid. For example, when only the main body is grasped by hand and lifted, the conventional open-close type storage is required. In the box, there was a problem that the lid was further opened due to gravity, and the CDR placed on the lid would drop.

Japanese Unexamined Patent Publication No. Hei. 8-164987 discloses an article storage box which can keep the lid open even when gripping and lifting only the main body. A protruding portion was formed on the surface of the main body, which abuts when opened at an angle, and suppresses further opening operation, and the protruding portion impairs the appearance of the storage box.

[0007] Further, a very small projection is provided on one of the main body and the lid, and a very small recess is provided on the other, so that the projection and the recess are temporarily locked when the lid is opened. It is conceivable that the lid can be kept open, but the small projections do not have enough locking force, so when the CDR is placed on the lid, only the main body is gripped and lifted. In this case, it is difficult to keep the lid open because the projection easily gets over the concave part due to the weight of the lid and the gravity of the CDR.

[0008]

[Problems to be solved by the invention]

 The present invention has been made in order to eliminate the above-mentioned disadvantages of the prior art, and has as its object the storage in which a lid can be opened and closed around a pair of bearings with respect to a main body. In the box, an arc-shaped groove having a central angle of at least 90 ° is formed on the main body side of the bearing portion, and moves along the arc-shaped groove on the lid side when the lid is opened and closed, and when the opening degree of the lid is maximized, the arc-shaped groove is formed. By forming a projection that abuts on the end of the optical disc to prevent further opening movement, it stops when the vertical plane when closed when the lid is opened is horizontal, and the optical disk is on the lid side. Even if the main body or the lid alone is gripped and lifted while a recording medium such as the above is placed, the opening of the lid can be maintained firmly as it is. Is to prevent falling That.

Another object of the present invention is to provide the above-mentioned configuration, wherein an arc groove having a center angle of 270 ° is formed on the main body side of the bearing portion, and the lid moves along the arc groove when the lid is opened and closed on the lid side of the bearing portion. When the degree of opening is maximized, an arc-shaped projection having a central angle of 180 ° is formed to abut against the end of the arc groove to inhibit further opening operation, and the lid is formed within a range of 90 °. An object of the present invention is to increase the strength of the protruding portion and make it possible to smoothly open and close the lid within a range of 90 ° by being configured to be capable of opening and closing.

[0010]

Means for Solving the Problems In short, the present invention (claim 1) is configured such that a lid can be opened and closed around a pair of bearing portions with respect to a main body, and when the lid is opened, a vertical plane when closed. In the storage box that is configured to stop at the point where it becomes horizontal, an arc groove with a central angle of at least 90 ° is formed on the main body side of the bearing, and along the arc groove when the lid is opened and closed on the lid side. When the opening of the moving lid is maximized, a protruding portion is formed which comes into contact with the end of the arc-shaped groove to inhibit further opening operation.

The present invention (Claim 2) provides a structure in which the lid can be opened and closed around a pair of bearings with respect to the main body, and when the lid is opened, the vertical plane when closed becomes horizontal. In the storage box configured to stop, an arc groove having a center angle of 270 ° is formed on the main body side of the bearing portion, and the opening of the lid moves along the arc groove when the lid is opened and closed on the lid side of the bearing portion. When it reaches the maximum, it forms an arc-shaped projection with a central angle of 180 ° that abuts against the end of the arc groove to prevent further opening, and the lid can be opened and closed within a range of 90 ° It is characterized by having comprised so that it might become.

[Embodiment of the invention]

 The present invention will be described below based on an embodiment shown in the drawings. The storage box 1 according to the present invention includes a main body 2 and a lid 3 in FIGS. 1 to 4, and the lid 3 can be opened and closed with respect to the main body 2 around a pair of bearings 4.

The main body 2 and the lid 3 are, for example, integrally formed of a transparent resin, respectively. When the storage box 1 is assembled, the main body 2 and the lid 3 have a rectangular parallelepiped shape. It has a height of about 135 mm, a depth of about 112 mm, and a thickness of 2 to 3 mm, and has a size suitable for accommodating, for example, a nonwoven case 6 containing a CDR 5.

As shown in FIG. 3, the main body 2 has a back surface 2a having a height of about 132 mm, a side surface 2b cut obliquely toward the front side, and a back surface 2a having a height of about 46 mm. A main pocket 2d is formed which is capable of storing about 50 non-woven cases 6 each having a thickness of about 10 mm and surrounded by the parallel first partition 2c. The first partition 2c and the front surface 2e are formed. A second partition 2f is formed at a position where the space between the two is divided into two, and sub pockets 2g and 2h are formed by the second partition 2f. The height of the front surface 2e and the second partition 2f is the same as that of the first partition 2c.

Since both sides 2i of the sub-pockets 2g and 2h are portions where the lid 3 overlaps, the width (the distance from one side 2i to the other side 2i) is formed to be narrow by the thickness thereof. In the center of both side surfaces 2i, arc grooves 2j each having a center angle of 270 ° on the main body side of the bearing portion 4 are formed.

The arc-shaped groove 2j has a width of, for example, 7.55 mm, from the starting end 2k at 12 o'clock in the timepiece to the end 2m which is a horizontal surface around the front 2e and downward. Most of the arc groove 2j other than the portion through which the second partition 2f passes penetrates the side surface 2i, and the shaft 2n is left in the center of the arc groove 2j in an arc-shaped island shape. ing.

On both side surfaces 2i, spherical small protrusions 2o are formed one by one. This is to apply a frictional force to the lid 3 when the lid 3 is closed so that the lid 3 can be easily maintained in the closed state.

Note that protrusions 2q are formed on the upper surfaces of the end surfaces 2p of the side surfaces 2b on both sides to suppress rattling in the width direction of the cover 3 when the cover 3 is closed.

The lid 3 comprises an upper surface 3a, a vertical surface 3b and both side surfaces 3c as shown in FIGS. 1, 2 and 4 to 7, and the width, height and depth are substantially the same as those of the main body 2. is there. Lower portions 3d of both side surfaces 3c are formed in an arc shape so that the opening and closing operation of the lid 3 can be easily performed, and an arc-shaped projection having a central angle of 180 ° is formed on the inner side of the side surface 3c on the lid 3 side of the bearing portion 4. 3e are integrally formed.

As shown in FIG. 6, the projection 3e moves along the arc groove 2j when the cover 3 is opened and closed, and when the opening of the cover 3 is maximized, it comes into contact with the terminal end 2m of the arc groove 2j. It is intended to prevent further opening movement by touching the terminal, and from a starting point 3f at 12 o'clock position in the clock to an end point 3g at 6 o'clock position around the vertical plane 3b and downward in the clockwise direction. For example, it is formed with a height of 2.3 mm and a width of 7.5 mm.

In the storage box 1, a gap between the protrusion 3e and the arc groove 2j is secured to 0.5 mm, and the protrusion 3e is fitted in the arc groove 2j to such an extent that the protrusion 3e can slide smoothly. It is in a state.

Although the center angle of the arc groove 2j of the main body 2 is set to 270 ° and the center angle of the projection 3e of the cover 3 is set to 180 ° in the above configuration, the present invention is not limited to this. The positions of the start end 2k and the end 2m, and the positions of the start end 3f and the end 3g of the projection 3e are not limited to those described above. In this embodiment, the lid 3 can be opened and closed within a range of 90 °. I just need.

Further, the opening / closing angle of the lid 3 is not limited to 90 °, but may be greater than 90 ° or less than 90 ° depending on the shape of the lid 3.

The present invention is configured as described above, and its operation will be described below. As shown in FIG. 4, the storage box 1 in which the lid 3 is in a closed state has no protrusions such as stoppers formed on the surface, and thus has a clean rectangular parallelepiped shape as a whole. At this time, the small projection 2o of the main body 2 applies a frictional force to the lower portion 3d of the lid 3, and the projection 2q of the main body 2 suppresses the play of the lid 3 in the width direction. It is maintained stably.

At this time, in the bearing portion 4, as shown in FIG. 6, the starting end 3f of the projection 3e of the lid 3 is in contact with the starting end 2k of the arc groove 2j of the main body 2.

As shown in FIG. 5, when the lid 3 is opened in the direction of arrow A, the lower part 3d of the lid 3 gets over the small projection 2o, and the projection 3e slides smoothly along the arc groove 2j. When the vertical surface 3b of the lid 3 becomes horizontal, that is, when the lid is opened by 90 °, the end 3g of the projection 3e abuts on the end 2m of the arc groove 2j, and the opening of the lid 3 is stopped.

The non-woven case 6 containing the CDRs 5 is usually stored in the main pocket 2d. For example, a plurality of unused CDRs 5 are temporarily put in the lid 3 and writing is performed. The operation of sequentially transferring the CDRs 5 that have been completed to the main pocket 2d is often performed.

During this operation, that is, when the CDR 5 is still mounted on the lid 3 in the fully opened state, even if only the main body 2 is gripped and lifted, the terminal end 3g of the projection 3e of the lid 3 is Since it is in contact with the end 2m, the fully open state is firmly maintained with a sufficient margin, the lid 3 does not open any more, and the CDR 5 does not drop. At this time, even if only the lid 3 is gripped and lifted, the main body 2 does not relatively open, and the non-woven case 6 stored in the main pocket 2d does not drop.

As described above, the storage box 1 can be opened and closed within a range of 90 ° and has no extra projections on its surface. Space.
