Description

  The present invention relates to a travel bag such as a suitcase, and more particularly to a bag including a box-shaped bag body that opens forward and a front lid that closes the opening of the bag body.

  As a travel bag such as a suitcase, a bag called a so-called soft case type is put into practical use. Such a bag includes a box-shaped bag body that opens forward, and a front lid that closes the opening of the bag body, and the front cover can be opened and closed by a fastener (for example, (See Patent Document 1 (FIG. 2)).

A basic configuration of the bag disclosed in Patent Document 1 will be described.
As shown in Patent Document 1, a box-shaped bag includes a bag main body that stores articles, and a front lid that is provided on the bag main body so as to be opened and closed by a fastener. The heel body constitutes a part of the front surface and five faces excluding the front face among the six faces constituting the heel, and the front lid constitutes most of the front face of the heel and closes the opening. .

  The bag main body includes a caster provided at the bottom, a handle provided at the top, and a carry bar provided so as to be able to be pulled out at the back. Generally, in order to lock the fastener that opens and closes the front lid, a TSA lock (locking mechanism certified by the Transportation Security Administration) is provided on the bag body, and the fastener puller is hooked on the TSA lock to lock.

  By the way, in the zipper type bag that opens and closes the front lid with a zipper, regardless of whether it is a soft suitcase type or a hard suitcase type, the opening is made with a reinforcing material such as a separate frame or piano wire to maintain the strength of the opening. It needs to be reinforced. Further, the parts to which the casters, carry bars, TSA locks, and the like are attached are reinforced and attachment parts are required, which increases the number of parts and the number of assembly steps.

  Therefore, there is a demand for a technique that can reduce the number of parts and reduce the number of assembly steps in a bag provided with a box-shaped bag main body that opens forward and a front lid that closes the opening of the bag main body.

JP 2014-27991 A

  This invention makes it a subject to provide the bag which can reduce an assembly man-hour while reducing the number of parts.

  The invention according to claim 1 is a bag comprising a box-shaped bag main body that opens forward and a front lid that is attached to the bag main body so as to be openable and closable, and the front cover is erected. Only the front surface of the heel is configured in the state, and the heel body includes a back wall portion that configures a back surface of the heel in an upright state, a bottom wall portion extending forward from a lower end portion of the back wall portion, and the back wall Left and right side wall portions extending forward from the left and right ends of the portion, and an upper wall portion extending forward from the upper end portion of the back wall portion, the back wall portion, the bottom wall portion, the left and right side wall portions, and the The upper wall portion is characterized by being an integrally molded resin.

  The invention according to claim 2 is provided with a caster mounting groove for mounting a caster on the bottom wall portion, and the caster mounting groove is formed in a T-shaped cross section and one end is opened to the side surface portion. A slide fitting portion having a T-shaped cross section that is slid and fitted into the mounting groove is provided.

  According to a third aspect of the present invention, the bag main body includes a drawable carry bar, an insertion hole for inserting the carry bar is provided in the upper wall portion, and the lower end portion of the carry bar is disposed inside the bottom wall portion. It is characterized in that a carry bar fixing groove for fixing to is provided.

  According to a fourth aspect of the present invention, the left and right edges of the upper wall portion are provided with corner members that reinforce the edge portions, and the corner members are provided with claws that engage with mounting holes formed in the side wall portions. It is characterized by.

  In the contrivance according to claim 5, the bag main body is provided with a cloth interior that protects the stored items inside, and an interior belt extending from the front side to the back side is provided in the interior, and the interior belt extending to the back side is a fastening member. It is characterized in that it is fastened to the bag body.

  The invention according to claim 6 is characterized in that the TSA lock for locking the front lid to the heel body is fastened to the heel body by a fastening member.

  In the invention according to claim 7, the bottom wall portion, the left and right side wall portions, and the upper wall portion each have a bottom wall extension portion, a left and right side wall extension portion, and an upper wall extension portion that extend to the front surface of the bag. An opening is formed by the edges of the wall extension, the left and right side wall extensions, and the upper wall extension.

  The invention according to claim 8 is characterized in that the front lid is opened and closed on the bag main body via a fastener.

  According to the first aspect of the present invention, the bag includes a box-shaped bag body that opens forward, and a front lid that is attached to the bag body so as to be openable and closable, and closes the opening. Only the front of the. Since the back wall portion, bottom wall portion, left and right side wall portions, and upper wall portion of the heel body are integrally molded resin, even if the box-shaped heel body opens forward, the heel body alone can be opened. The rigidity can be improved, and parts for reinforcing the opening as in the prior art are not required. For this reason, even if it is a scissors provided with the box-shaped scissors main body opened ahead and the front lid which closes the opening of this scissors main body, a number of parts can be reduced and an assembly man-hour can be reduced.

  According to the second aspect of the present invention, a caster mounting groove for mounting a caster is provided on the bottom wall, and the caster mounting groove is formed in a T-shaped cross section and one end is open to the side surface. The caster is provided with a slide fitting part with a T-shaped section that slides and fits into the caster mounting groove, so the caster can be easily attached to the bottom wall part of the cocoon body, reducing assembly man-hours can do.

  Furthermore, since the back wall part, the bottom wall part, the left and right side wall parts, and the top wall part are integrally molded resin by injection molding, the bottom wall part itself is reinforced, Therefore, it is not necessary to provide a reinforcing member for receiving casters, and the number of parts can be reduced.

  In the invention according to claim 3, the bag body is provided with an insertion hole for inserting the carry bar in the upper wall portion, and a carry bar fixing groove for fixing the lower end portion of the carry bar to the bottom wall portion inside the bottom wall portion. Since it is provided, it can be easily assembled simply by inserting a carry bar into the bag body and fastening it with a fastening member.
