Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a carrying case having an improved clasp and opening / closing mechanism.

(Prior Art) Generally, there are various types of carrying cases, but for example, a box-shaped attache case is often used for business.

This attache case had a thickness of 5 cm or more and had a large internal volume, and its structure was strong enough to carry a heavy object, and the structure of the clasp was complicated.

However, when inserting thin and light items such as catalogs, pamphlets, and documents, the conventional attache case is too large, and it is too heavy and heavy to use, which is inconvenient to carry. Further, in the conventional attache case, there is a problem in that the pencil cannot be closed by the opening / closing hinge on the bottom side of the case when the case is closed. Also, if the clasp comes off while carrying the carrying case with the handle,
There was a problem that the case opened and the documents were scattered.

(Problems to be solved by the invention) The present invention has been made in view of such a point, and the clasp and the opening / closing structure are simple and lightweight, and are inexpensive. The present invention provides a handbag case that is highly fashionable and convenient for a salesman to carry a catalog, pamphlet, documents, etc.

(Means for Solving Problems) The carrying case of the present invention is configured by combining two side plate portions 1A and 1B which can be opened and closed as shown in FIGS. 1 to 5.

As shown in FIG. 2, the side plate portions 1A and 1B have, for example, square bars bonded along the four edges of one side of a square plate member 2,
This is the rising portion 3. Further, the lower rising portions 3 of the side plate portions 1A and 1B forming the bottom portion of the case are attached with rods each having a triangular cross section whose cross section is gradually thinned upward.
A V groove is formed between them.

An outer sheet 4 is attached to the outer surfaces of the side plate portions 1A and 1B, and an inner sheet 5 is attached to the inner surfaces thereof. In addition, the V between the rising portions 3 and 3 having a triangular cross-section that constitutes the bottom of the case
The outer sheet 4 is continuously attached to the bottom surface of the groove, the inner sheet 5 is attached to the inner surface of the V groove of the rising portions 3 and 3, and the rising portions 3 and 3 are connected from both sides. The space is a hinge 6 for opening and closing the case.

As the outer sheet 4 and the inner sheet 5, thin and flexible sheets such as decorative paper, wallpaper, cloth cloth, vinyl sheet and leather sheet are used.

In addition, a third part is provided at the center of the upper rising part 3 of the side plate 1A on one side.
As shown in the figure, the convex portion 7 is formed, and the handle 8 is joined to the upper surface thereof. As shown in FIG. 4, a clasp 10 having a U-shaped cross section having an opening 9 slightly wider than the thickness of the case formed by combining both side plate portions 1A and 1B is formed on the outer surface of the side plate portion 1A near the handle 8 as shown in FIG. Is provided, and one end of the clasp 10 is openably and closably connected by a clasp opening / closing hinge 11.

The clasp 10 is formed by bending a metal plate such as stainless steel into a U-shaped cross section.

Further, as shown in FIG. 5, the handle 8 is formed to have a size such that the clasp passage portion 8a, which is slightly larger than the turning locus of the clasp 10 having a U-shaped cross section, is opened.

Further, the side plate portion 1B that opposes the convex portion 7 to which the handle 8 is attached
At the center of the upper rising portion 3 of the above, there is formed a concave portion 13 to be fitted thereinto, and the receiving metal 12 is fitted therein, and when the clasp 10 is rotated, it hits the receiving metal 12 and the both side plate portions 1A and 1B are attached. It is designed to be sandwiched.

In the figure, reference numeral 14 is a frame having an L-shaped cross section, which is attached to the upper portion of the side plate portion 1A and the inside of the right and left rising portions 3.

(Operation) When the carrying case having the above structure is opened, as shown in FIG. 5, the clasp 10 is pivoted upward, passed through the inside of the handle 8 to the side plate portion 1A side, and then, as shown in FIG. Side plate 1B
open.

At this time, the case opening / closing hinge 6 at the bottom connecting the side plate portions 1A and 1B has a flexible outer sheet 4 and inner sheet 5 which are flexible.
Since it is formed of, it can be opened and closed easily.

Also, when closing the carrying case, align the side plate portions 1A and 1B and then attach the clasp 10 as shown in FIG.
The side plate part 1A and the side plate part 1B fitted with the receiving plate 12 are clamped inside the opening 9 having a U-shaped cross section formed slightly wider than the thickness of the case by rotating through the inside of the clasp passage part 8a. The case is locked.

Further, the rising portions 3 and 3 having a triangular cross-section at the lower portions of the side plate portions 1A and 1B have a V-groove formed so that their cross-sections gradually become thinner toward the upper side, so that they become a relief when a pencil or the like is caught. . That is, if this is configured by a square rod having a rectangular cross section, the case opening / closing hinge 6 formed by the outer sheet 4 and the inner sheet 5 may be broken if a pencil or the like is caught when the case is closed. Is.

The frame 14 having an L-shaped cross section attached to the upper portion of the side plate portion 1A and the insides of the right and left rising portions 3 prevents an object placed inside from being caught in the gap between the side plate portions 1A and 1B and prevents falling. At the same time, it acts as a rain barrier.

When the clasp 10 is rotated through the inside of the clasp passage portion 8a and the case is locked, when the handle 8 is carried in the hand, the grip 8 moves from the turning locus of the clasp 10 having a U-shaped cross section. Since the slightly large clasp passage 8a is opened,
When the clasp 10 comes off, it cannot be rotated by touching the hand, which prevents the clasp 10 from coming off and opening the case during transportation.

FIG. 6 shows another embodiment of the present invention, in which the rising portions 3 and 3 at the bottom of the side plate portions 1A and 1B, which are the bottom surfaces of the case, are formed by forming the hypotenuse of the triangular cross section into a concave curved surface and moving upward. The U-grooves are formed between the thinly formed layers.

This structure also prevents a pencil or the like from being caught when the case is closed, and protects the case opening / closing hinge 6 formed of a sheet.

(Effects of the Invention) As described above, according to the carrying case according to the present invention, the receiving member can be securely locked with an extremely simple structure in which the metal plate is bent in a U-shaped cross section, and the hinge for opening and closing the case is Since it is made of a sheet attached to the surface of the side plate, the opening and closing structure is simple and lightweight, and it can be manufactured at low cost.
You can prevent the pencil from being caught and the clasp from coming off during transportation,
It is excellent in fashionability and is particularly suitable for a salesperson to carry a catalog, brochure, documents, etc.
