Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a case in which various devices such as a video device including a video camera, a tape recorder, and an OA device are housed as a set and used for portable use, and various other types. Regarding the bag.

[Prior Art] A portable case or bag for accommodating a video device or the like and carrying it is used to protect the safety of the contents against shock.
Since the hardness of the guard and the like are required, conventionally, as shown in FIG. 5, the outer body 1 made of a hard cortical plastic sheet and the inner body 2 are polymerized to form one case body. However, since the manufacturing method requires the rim frame 3 at the peripheral portion of the case body as shown in FIG. 6, the outer body 1, the inner body 2 and the rim frame 3 are separately molded. First, the rim frame 3 is first fitted and sandwiched between the end edge portions 1a of the outer body 1, and then the inner body 2 is superposedly fitted on the inner surface of the outer body 1 so as to integrally join the three members. It is a thing. Then, it is hinge-coupled to the case lid side exterior body corresponding to the case body to form one carrying case or bag. Therefore, it is necessary to separately manufacture the lip frame and attach it to one case body side in advance, and then attach it to the case lid side, which complicates a series of operations from molding to assembly. In addition, the number of steps is large, which causes a high cost, and there is a problem in terms of durability.

[Problems to be Solved by the Invention] The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to separately manufacture a lip frame and to provide a case body. A series of steps from molding to fitting of the outer body and the inner body and joining with pins can be performed easily and quickly without using a means of sandwiching the outer body and fitting the inner body on the outer body. At the same time, it aims to provide a bag with excellent durability.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a bag according to the present invention comprises an outer body formed by molding a plastic sheet of a hard cortex into a concave shape and a molded body of a same or different hard resin sheet. In a bag which is formed by internally and externally double-fitting as a case body, an edge of the interior body is bent outwardly, and the inner surface of the interior body and a folded piece are formed along the entire circumference of the portion. , And the connecting piece between them form an integrally formed rim frame having a U-shaped engaging groove, and insert the end edge portion of the exterior body into the engaging groove of the rim frame to integrally join them. It will be.

Further, the interior body is formed integrally with a sheet body made of a hard resin on the outside and a sheet body made of a foamed resin being polymerized and adhered inside to form a double layer.

[Operation] As shown in FIG. 4, the exterior body 20 and the interior body 30 are separately molded, and at this time, the edge frame of the interior body 30 is integrally formed with the rim frame 34. The lip frame 34 is formed in a shape in which the end edge of the interior body 30 is bent outward, and has a U-shape that is opened outwardly in the interior body inner surface 30a, the folding piece 31, and the connecting piece 32. Which has the engaging groove 33, and is entirely formed by injection molding.

Next, the inner body 30 is fitted to the inner surface of the concave portion of the outer body 20, and at this time, the end edge portion 21 of the outer body 20 is engaged with the U-shaped engagement of the rim frame 34 at the end edge of the inner body 30. It is designed to be inserted in the groove 33.
The case body 10 is configured in this way. Case body
Two sets of 10 are symmetrically arranged or symmetrically arranged, and if they are formed into a palm shape and are joined by a hinge metal fitting 50 at the bottom, the first and second
The portable bag shown in the figure is completed.

[Embodiment] The outer casing 20 and the outer casing 30 are both formed of ABS resin by vacuum molding, and the inner casing is formed by injection molding into a desired concave shape, respectively. obtain.

When providing the foamed resin sheet body 40 on the interior body 30, use AB
The S resin sheet body and the foamed resin sheet body 40 are polymerized and integrally molded.

On the coupling piece 30 of the rim frame 34, one is integrally formed with the protruding portion 34a, and the corresponding coupling piece is integrally formed with the recessed portion 34b. As shown in FIG. Engage when the two are closed.

When opening and closing the case body 10.10, friedlock 5
Operate 1 to enable locking and unlocking. The slide lock 51 is formed with concave recesses 52 on both left and right sides of the case body, and is attached to the concave recesses 52 so as to be slidable in the vertical direction.

[Effects of the Invention] As described above, the present invention forms the end edge of the interior body in the outwardly bent shape, and the inner surface of the interior body and the folded piece, and the connecting piece between them are formed on the entire circumference of the portion. In addition to integrally forming a rim frame having a U-shaped engaging groove, the end edge portion of the exterior body is inserted into the engaging groove of the rim frame and integrally joined,
When the inner body is molded with the resin sheet, the rim frame is integrally formed at the edge portion, so that it is not necessary to use a separate body conventionally, and the man-hours and the manufacturing labor are simplified. After molding the inner body and outer body, when fitting both,
Since the end edges of the outer casing can be simultaneously clamped and integrally joined to the rim frame, the assembly is easy, the structure is simple, the durability is high, and the cost is advantageous.
