Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a case such as an attache case or a trunk case in which a side plate of a case body is made of metal.

(Prior Art) Conventionally, for example, a plate member of an iron plate formed by bending a lid body and a bottom body into a substantially U-shaped cross section, and bending the upper and lower side edge ends so as to further wind inward, The bag is made of a synthetic resin edge member formed so as to cover both end corners, and a hard material formed by connecting the lid body and the bottom body with hinges makes the bag a Japanese Utility Model Publication No. 50-32309. Is known by.

(Problems to be solved by the invention) However, in the case of the bag having this structure, in order to attach the edge member to the lid and the bottom body, an engaging claw is projected on the edge member to form the lid body and the bottom plate. Since the simple structure of merely engaging with the holes provided at the edge of each plate member is adopted, the attachment of the edge member to the lid body and the bottom body cannot be performed sufficiently firmly. There were problems such as.

(Means for Solving Problems) The present invention is directed to a horizontally long rectangular front plate 3, a rear plate 4 having the same shape as the front plate 3 and opposed to the front plate 3 with a required space therebetween, and the front plate 3
Also, in the case main body formed in a casing by the four side plates 1 connected to the periphery of the rear plate 4, each side plate 1 is made of metal such as aluminum, and the inner wall 5 and the outer wall 6 are connected by the ribs 2. It has a double structure and its center is 2 in the longitudinal direction.
It is divided and can be opened and closed freely. Both side edges of its long side are bent in the direction of the inner wall toward the elbow by 90 ° and the side edges of the front plate 3 and the rear plate 4 are fitted into the ends. An edge frame portion 2 having a joining groove 8 for forming the side plate 1 is integrally formed.
Is formed at both ends in the longitudinal direction of each of the side plates 1, and each side plate 1 has fitting protrusions 11 at both ends at an angle of 90 °. An object of the present invention is to solve such a problem by providing a case characterized in that the inner wall 5 of each side plate 1 and the corner joint frame 10 fixed by screws 12 are connected to each other.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings with respect to an attache case.

This attache case is composed of a horizontally long rectangular front plate 3, a rear plate 4 having the same shape as the front plate 3 and facing the front plate 3 at a required distance, and four side plates connected to the peripheral edges of the front plate 3 and the rear plate 4. 1 and 1 form a casing. Each side plate 1 is made of a metal such as aluminum, and has a double structure in which an inner wall 5 and an outer wall 6 are connected by a rib 7. The central part of the side plate 1 is divided into two parts in the longitudinal direction so that opening and closing can be freely performed. An edge frame portion having a joint groove 8 bent along both side edges of its long side toward the inner wall in a 90 ° elbow shape to fit the side edges of the front plate 3 and the rear plate 4 at its ends. 2 are integrally formed. Joining holes 9 are provided at both ends of the side plate 1 in the longitudinal direction, and each side plate 1 is connected to the other side plate 1 via a plastic elbow-shaped corner joint frame 10 at both ends thereof. That is, the corner joint frame 10 has fitting protrusions 11 at both ends at an angle of 90 °,
The protrusions 11 are fitted into the joint holes 9 of the two adjacent side plates 1 and fixed to the inner wall 5 of each side plate 1 by the screws 12.

(Operation and effect) In the present invention, the side plates 1 of the front plate 3 and the rear plate 4 are all made of metal such as aluminum and the inner wall 5 and the outer wall 6 as described above.
Has a double structure connected by ribs 7. The central part is divided into two parts in the longitudinal direction to allow opening and closing, and both side edges of the longitudinal side are 90 ° elbow shape toward the inner wall. An edge frame portion 2 having a joining groove 8 which is bent at the end and into which the side edge portions of the front plate 3 and the rear plate 4 are fitted is integrally formed, and is joined to both ends of the side plate 1 in the longitudinal direction. A hole 9 is provided, and each side plate 1 has fitting protrusions 11 at both ends at an angle of 90 °. The protrusions 11 are fitted into the joint holes 9 of two adjacent side plates 1, respectively. Since the inner wall 5 and the corner joint frame 10 fixed by the screws 12 are connected to each other, the side plates 1 are securely and firmly fixed to the front plate 3 and the rear plate 4 as compared with the above-mentioned known ones. Can be done
The present invention has the effect of sufficiently solving the above problems.
