In the present embodiment, the front upper wall portion 51 and the left and right tongue pieces 71a are each made of a plastic thin plate main body 27, and a hard resin reinforcement attached to the outside of the wall main body 27. A convex portion 92 is formed on the reinforcing portion 28 so as to include the portion 28.

The moving member 42 is provided at the front side edge portion of the rear upper wall portion 52, and more specifically, it is formed at the lower end portion thereof at the engaging position P as shown in FIG. The latching portion 42a having a U-shaped cross section sandwiches the engaging portion 41, and the latching portion retracts from the engaging portion 41 at the retracted position Q. In this embodiment,
The rear upper wall portion 52 and the left and right wall portions 9 are composed of a thin plate-shaped wall body 25 made of plastic and a reinforcing portion 26 made of hard resin attached to the outside of the wall body 25. A guide rail R for guiding the sliding movement of the moving member 42 is formed on the upper surface of the reinforcing portion 26.
The lower end portion of the moving member 42 is engaged with each other. Reference numeral 42e is a guide member that engages with a guide hole 13 to be described later and serves to guide the sliding movement of the moving member 42 together with the guide rail R.

As shown in FIGS. 2 and 3, the operating portion 43 has a lock position M in which the opening portion 12 formed on the upper surface of the base of the handle 11 is fitted from the inside of the handle 11 and the opening portion 1.
2 to the retracted position Q side of the moving member 42, and is slidably provided between the moving member 42 and the release position N fitted into the guide hole 13 formed inside the handle 11. To the engagement position P,
The moving member 42 is positioned at the retracted position Q at the release position N. In particular, in the present embodiment, the operating portion 43 is a disc-shaped member, and on the upper surface thereof, the operating portion 43 is slid to the release position N with a finger or the like.
The pressing surface portion 43a slightly inclined upward toward the release position N side
Has been formed. Further, the shape of the opening 12 is substantially matched to the shape of the operating portion 43 in plan view, and at the lock position M, the upper surface of the operating portion 43 and the surface of the handle 11 are smoothly and continuously continued. . In addition, in the present embodiment, the opening 12 has a substantially circular shape.

As shown in FIGS. 2 and 3, the transmission mechanism 44 is formed on the bottom surface of the opening 12 and a pair of elastically deformable bending members 44 a interposed between the operating portion 43 and the moving member 42. The inclined surface 44b is used.

Each bending member 44a has a hanging portion 44c that hangs downward from the moving member 42, and extends obliquely upward from the lower end portion of the hanging portion 44c toward the engagement position P, and is connected to the operating portion 43 at the tip portion. The extended portion 44d is formed so as to elastically deform so that the tip of the extended portion 44d moves up and down. More specifically, the bending member 44a is such that when a downward pressing force acts on the extending portion 44d, an elastic return force that repels the pressing force is generated, and the moving member 42 is attached to the base of the handle 11. It serves as an elastic body that elastically biases the upper surface. In the present embodiment, the operating portion 43, the bending member 44a, and the moving member 4 are used.
2 and 1 are integrally molded.

The inclined surface 44b is inclined downward from the lock position M side of the operating portion 43 toward the retracted position Q side, and guides the sliding movement of the operating portion 43 between the locked position M and the retracted position Q. Play a role in.

In the handle 11, when the moving member 42 is located at the engagement position P, the end face of the moving member 42 on the engagement position P side and the left and right end faces of the handle 11 contact each other.
It is provided on the reinforcing plate 52 of the rear upper wall portion 52. In particular, in the present embodiment, the left and right end surfaces of the handle 11 have substantially the same shape as the end surface of the moving member 42 on the engagement position P side. More specifically, the end surface of the moving member 42 on the engagement position P side has a U-shaped cross-section that inclines downward to the engagement position P side and opens downward. On the other hand, the left and right end surfaces of the handle 11 have a U-shaped cross section, which is inclined upward toward the moving member 42 side and opens downward.

In the file case 1 configured as described above, in order to unlock the storage port 3 in the closed state, as shown in FIG.
Is pressed with a finger or the like. Then, the operation portion 43 retracts from the opening portion 12 against the elastic return force of the bending member 44a, slides along the inclined surface 44b to the release position N side, and as shown in FIG. It will fit in. As a result, the moving member 42 that was in the engaging position P is located in the retracted position Q, the moving member 42 and the engaging portion 41 are disengaged, and the upper front wall portion 71 is bent forward and stored. It becomes possible to open the part S upward. When the finger is released at the retracted position Q, since the elastic return force acts on the bending member 44a, the operation portion 43 comes into contact with the inner wall surface of the handle 11 forming the guide hole 13, and the operation is performed. It is possible to fix the portion 43 to the release position N, in other words, to fix the moving member 42 to the retracted position Q.

On the other hand, in order to lock the closed state of the storage port 3, the moving member 42 is moved to the engaging position P with a finger or the like. As a result, the operation portion 43 retracts from the guide hole 13 and slides the inclined surface 44b to the lock position M side, is fitted into the opening portion 12, and is located at the lock position M. At the locked position M, as shown in FIG. 2, since the opening edge of the opening 12 and the peripheral edge of the operating portion 43 are in contact with each other, the downward pressing force does not act on the operating portion 43. As long as the operating portion 43 is in the locked position M, the moving member 42 can be held in the engagement position P. Then, at the engaging position P of the moving member 42, the end of the moving member 42 on the engaging position P side and the left and right ends of the handle 11 come into contact with each other.

Therefore, in such a file case 1, the moving member 4 is at the engaging position P of the moving member 42.
The end of the handle 11 on the side of the engagement position P and the left and right ends of the handle 11 come into contact with each other, so that the surface of the handle 11 and the upper surface of the moving member 42 continuously and smoothly continue, and the handle 11 and the moving member. Since the shape of the moving member 42 is integrated with that of the moving member 42, it is difficult for the moving member 42 to be caught by clothes or the like. Further, since the operating portion 43 is provided at the base of the handle 11, when an article such as a document is put into or taken out of the storage portion S, the moving member 42 is operated so that the hand is once released from the handle 11 or placed on a table or the like. The storage opening 3 can be smoothly opened and closed without placing it.

Further, since the handle 11 is provided on the rear upper wall portion 52, which itself does not move when the storage port 3 is opened and closed, the storage port 3 can be opened and closed properly.

Furthermore, since the file case 1 in this embodiment is a so-called single-open type in which the upper front wall portion 71 is bent to open the storage port 3, the rear wall portion 8 is placed downward. It also becomes possible to favorably open and close the storage opening 3 when the file case 1 is placed on a table or a knee.

The present embodiment is not limited to the above illustrated example. For example, if the finger is released when the operation unit is located at the release position, the operation unit may automatically return to the lock position. Further, the lock mechanism may be provided only on one root side of the handle. Further, a compression spring may be used as the elastic body. In addition, the bending member is not limited to a pair as in the present embodiment.
In addition, various modifications can be made without departing from the spirit of the present invention.

[0027]

As described above, according to the bag of the present invention, since the moving member is structurally integrated with the handle at the engaging position, the moving member is less likely to be caught on clothes and the like. Since the part is provided on the handle, you can open and close the storage opening smoothly when you move items in and out of the storage part without having to remove the hand from the handle or place it on a table etc. to operate the moving member. You will be able to do it.
