  However, a conventional file storage box that is provided with an opening on the front surface and that is opened by rotating the lid upward needs to maintain the open state by holding the lid opened on the upper side by hand when taking out the file inside. However, there was a problem that the work of taking out the file becomes troublesome.

  In addition, the file storage box that can be opened by rotating the lid downward has a problem that when the file storage box is placed in a high place, the opened lid protrudes toward the front, which obstructs the file loading / unloading work. .

  Therefore, there has been proposed an apparatus in which the lid is rotated upward to be opened and the lid is slid inside the box along the upper surface of the file storage box. However, this file storage box has a problem that its configuration is complicated and expensive.

  The present invention has been made in view of such problems, and it is an object of the present invention to provide a file storage box that can easily take out a file even when placed in a high place or a low place and can simplify the configuration. To do.

The present invention employs the following means in order to solve the above problems.
That is, the present invention
A file storage box that can store multiple files,
A storage box body provided with an opening through which the file is taken in and out;
A lid rotatably connected to a recess provided at an edge of the opening to open and close the opening;
It is characterized by providing.

The file storage box of the present invention can be formed without being restricted by the material, such as cardboard, cardboard, and resin sheet. Even when the file storage box is placed in a relatively high place, the file can be easily put in and out from the front side by opening the lid.

  In addition, since the lid is connected to the recess at the edge of the opening, the opening can be opened larger than usual, and the file loading / unloading operation is facilitated. Also, since the opening is wide open, it is easy to check the file inside even when the file storage box is placed in a relatively low place.

  Here, the lid can be formed in a substantially L-shaped cross section by a long side portion that opens and closes the opening and a short side portion connected to the recess. With this configuration, when the lid is closed, the short side portion and the long side portion can be substantially flat with the outer surface of the storage box body.

  Moreover, it can be set as the structure which has a guide means to guide opening and closing of the said lid | cover. In this case, the lid can be opened and closed stably.

  Further, the lid may have a slide plate that moves along the inner surface of the storage box body when the lid is opened and closed. In this case, the strength of the lid can be increased.

  The guide means may have a groove provided in one of the storage box main body or the slide plate and a pin provided in the other and inserted into the groove. Thereby, the structure of a guide means can be simplified.

  The groove may include a first arc portion that guides the rotation of the long side portion of the lid and a second arc portion that guides the rotation of the short side portion.

  In this case, since the rotation of the short side portion and the long side portion of the lid connected in a substantially L-shaped cross section is guided by separate arc portions, the lid can be opened and closed smoothly and reliably.

  Moreover, it can be set as the structure which has an open state holding means to hold | maintain the said lid | cover in an open state. In this case, when the lid is opened, the open state of the lid can be maintained without grasping the lid by hand, so that the file can be taken in and out easily.

  The open state holding means is formed in a groove shape that is provided continuously to the second arc portion in the guide groove and has a groove width narrower than that of the second arc portion so as to limit the movement of the pin. Can be configured.

  The storage box body includes an upper plate portion that forms the opening, both side plate portions that are orthogonal to the upper plate portion, a bottom plate portion that is parallel to the upper plate portion and orthogonal to the both side plate portions, and A rear plate portion disposed on the opposite side, and a substantially U-shaped reinforcing member that is inserted into the storage box body and disposed along the both side plate portions and the bottom plate portion.

  With this configuration, the strength of the storage box body can be increased. In particular, it is possible to reduce the load on the corners of the bottom plate part and the side plate part in the storage box body (dispersion of load) and prevent the corners from being cut.

  Moreover, it can be set as the structure which has the protrusion part which contact | abuts to the said upper board part of the said storage box main body, and restrict | limits the movement of the said reinforcing member in the edge of the said reinforcing member. With this configuration, the reinforcing member can be stably held in the storage box body.

The slide plate of the lid may be inserted between the side plate portions of the storage box body and the reinforcing member. In this case, the slide plate can be slid with good stability.

  The lid has an upper lid that opens and closes substantially the upper half of the opening, and a lower lid that opens and closes substantially the lower half of the opening, and the upper lid is rotatable to the bottom of the recess in the storage box body. When the lid is closed, the end portion of the upper lid and the end portion of the lower lid can be configured to overlap each other.

  With this configuration, when the lid is opened, the distance that the tips of the upper lid and the lower lid protrude toward the front can be shortened, so that the lid can be opened even in a narrow space.

  In addition, the storage box body, the slide plate of the lid, and the reinforcing plate are provided with handle holes that are arranged in alignment, and the peripheral wall portions of these handle holes are separated by the storage box body and the slide plate. It can be configured to be reinforced heavy and further reinforced in triplicate by the storage box body, the slide plate and the reinforcing plate. With this configuration, it is possible to prevent the peripheral wall portion of the handle hole from being cut.

  Moreover, the corner | angular part which contacts the said cover in the said side plate part can be formed in circular arc shape. With this configuration, the lid can be opened and closed smoothly, and the corners of the side plate portion can be prevented from being damaged by the opening and closing of the lid.

  The side plate portion may be provided with a notch that avoids the influence of the operation of the hinge. Thereby, it is possible to prevent the side plate portion from being cut by the operation of the hinge when the lid is opened and closed.

  According to the present invention, since the lid is pivotally connected to the concave portion provided at the edge of the opening, the opening can be opened more greatly, and the work of taking in and out the file therein is facilitated. Furthermore, even when the file storage box is placed at a low place, it becomes easy to check the file inside from a position higher than the file storage box, so that the file can be easily put in and out.

FIG. 10 shows a state in which the lid 13 of the file storage box 1 is completely closed. In this state
The short side portion 31 of the lid 13 is substantially flush (flat) with the upper plate portion 21 of the storage box body 12. Further, the opening 11 of the storage box body 12 is completely closed by the long side portion 32 of the lid 13.

  Next, the operation of the file storage box 1 will be described. In the state where the lid 13 is completely closed, as shown in FIG. 11, the pin 45 of the storage box body 12 is positioned on the end portion side of the first arc portion 41 of the guide groove 35 in the slide plate 33 of the lid 13. ing.

  From this state, when a force in the direction C for opening the lid 13 is applied, the first arc portion 41 in the guide groove 35 of the slide plate 33 moves along the pin 45 as shown in FIG. And the moving direction of the long side part 32 is controlled.

  As a result, the long side portion 32 of the lid 13 rotates about the intersection 36 with the short side portion 31 in the direction C away from the opening 11. This is because the first arc portion 41 is formed in an arc shape with the intersection point 36 as the center.

  Since the slide plate 33 is separated from the short side portion 31, even if the long side portion 32 rotates, the short side portion 31 hardly rotates.

  When the rotation of the long side portion 32 proceeds and the second arc portion 42 of the guide groove 35 in the slide plate 33 reaches the pin 45 as shown in FIG. 12, the rotation of the long side portion 32 substantially stops.

  When a force in the direction C that further opens the lid 13 is applied, the second arc portion 42 that is curved in the opposite direction to the first arc portion 41 is relatively moved along the pin 45 as shown in FIG. Moving.

  As a result, a force in the upward direction D acts on the long side portion 32 of the lid 13, and the short side portion 31 rotates about the hinge 28 in a direction E that rises with respect to the upper plate portion 21.

  Then, as shown in FIG. 14, when the open state holding portion 43 of the guide groove 35 reaches the pin 45, the short side portion 31 of the lid 13 is raised at a substantially right angle with respect to the upper plate portion 21, and the long side portion 32 is arranged substantially parallel to the upper plate portion 21.

  In this state, since the relative movement of the pin 45 is restricted by the open state holding portion 43 and the movement of the slide plate 33 is restricted, the lid 13 can be prevented from being inadvertently closed. Accordingly, since the open state can be maintained without grasping the lid 13 by hand, the file loading / unloading operation is facilitated. Since the lid 13 is opened upward, the file can be taken in and out from the front of the file storage box 1 without the lid 13 getting in the way.

  Further, in this case, the distal end 32a of the long side portion 32 is arranged so as to be shifted to the storage box body 12 side. As described above, the long side portion 32 is arranged on the upper side of the upper plate portion 21, and the tip 32a of the long side portion 32 is arranged so as to be shifted to the storage box body 12 side. Compared to the case where the distance between the bottom plate portion 24 of the storage box body 12 and the tip 24a is directly connected to the edge 11a of the opening 11 without provision of the recess 27 and the short side portion 31. growing.

  Therefore, even when the file storage box 1 is arranged at a position lower than the human eye, it is easy to check the file in the storage box body 12.

  Moreover, since the long side part 32 of the lid | cover 13 is arrange | positioned substantially parallel to the upper board part 21, even if there exists an obstruction on the upper side when opening the lid | cover 13, a comparatively narrow clearance gap between the obstructions If there is (slightly wider than the length of the short side portion 31), the lid 13 can be completely opened.

  Further, since the reinforcing member 14 is inserted into the storage box main body 12 and the protrusion 55 of the reinforcing member 14 abuts on the upper plate portion 21 of the storage box main body 12, the strength of the storage box main body 12 is increased and the reinforcement is strengthened. The position shift of the member 14 and the falling of the left and right side plates 51 and 52 can be prevented.

  In addition, since the pins 45 provided on the left and right side plate portions 22 and 23 of the storage box body 12 are covered with the left and right side plates 51 and 52 of the reinforcing member 14, when the file is taken in and out of the storage box body 12, the file is stored. It is possible to prevent the pin 45 from being caught.

  In addition, since the inner surface of the file storage box 1 is covered with the reinforcing member 14 and becomes flat, it is possible to work smoothly when a file is taken in and out.

  Further, since the slide plate 33 of the lid 13 is inserted and slid between the left and right side plate portions 22 and 23 of the storage box body 12 and the side plates 51 and 52 of the reinforcing member 14, the opening and closing of the lid 13 is stabilized. Moreover, it can avoid that the slide plate 33 contacts the inside file and the file or the slide plate 33 is damaged.

  When the lid 13 is closed, the handle hole 26 of the storage box body 12 for lifting the file storage box 1, the handle hole 34 of the slide plate 33 of the lid 13, and the handle hole 54 of the reinforcing member 14 are aligned. The

  As a result, the peripheral wall portion of the handle hole 26 is double reinforced by the side plate portions 22 and 23 and the slide portion 33 of the storage box body 12, and further, triple by the side plate portions 22 and 23, the slide plate 33 and the reinforcing member 14. Reinforced. Therefore, when the file storage box 1 is lifted using the handle hole 26 or the like, the handle hole 26 or the like can be prevented from being damaged.

  Further, when the file storage box 1 is stored or transported, the file storage box 12 and the lid 13 are unfolded and can be assembled easily when used, which is convenient.

<< Second Embodiment >>

The upper lid 74 is rotatably connected to the concave portion 27 of the upper plate portion 21 in the storage box body 12 via a hinge 28.

  The upper lid 74 is configured in substantially the same manner as the lid 13 of the first embodiment. However, the long side portion 76 of the upper lid 74 is formed in a size that opens and closes substantially the upper half of the opening 11. In addition, a notch 77 having a predetermined length is provided at the center of the lower side of the upper lid 74.

  The lower lid 75 is formed in a flat plate shape so as to open and close substantially the lower half of the opening 11. The lower lid 75 is rotatably connected to the lower edge of the opening 11 in the storage box body 12 via a hinge 78. In addition, an arc-shaped tongue piece 79 is provided at the center of the tip of the lower lid 75. Arc-shaped concave portions 80 and 80 are provided at both corners of the tongue piece 79.

  FIG. 16 shows a state in which the lid 73 of the file storage box 7 is completely closed. In this state, the end portion 74 a of the upper lid 74 and the end portion 75 a of the lower lid 75 overlap each other, and the end portion 74 a of the upper lid 74 is disposed on the lower side (back side) of the end portion 75 a of the lower lid 75.

  Further, the tongue piece 79 of the lower lid 75 is inserted into the inside of the storage box main body 12 through the notch 77 of the upper lid 74. Thereby, since the lower lid 75 arrange | positioned above the upper lid 74 is latched by the upper lid 74, it can suppress that the upper lid 74 and the lower lid 75 open carelessly.

  When opening the lid 73, a finger or the like is put on the concave portions 80, 80 at the tip of the lower lid 75, and the lower lid 75 is pulled forward. Thereby, as shown in FIG. 17, the lower lid 75 rotates and opens downward, and the end 74a of the upper lid 74 is exposed. As a result, the upper lid 74 can be opened upward.

  In the file storage box 7, since the lid 73 is divided into an upper lid 74 and a lower lid 75, when the upper and lower lids 74 and 75 are opened, the distances at which the tips 74a and 75a of the upper and lower lids 74 and 75 protrude forward. Can be reduced. Therefore, the lid can be opened even in a relatively narrow place.

  Further, when the lid 73 is closed, the end portions 74a and 75a of the upper and lower lids 74 and 75 are overlapped, so that it is possible to prevent a gap from being formed between the upper and lower lids 74 and 75.

  Furthermore, since the upper lid 74 opens larger than usual, similarly to the lid 13 of the first embodiment, the file inside can be confirmed reliably from above.
