Description

  The present invention relates to a frameless suitcase used for traveling or the like, and more particularly to a suitcase in which bending caused on the caster arrangement surface due to the weight of the load in the case when the caster is moved is reduced.

  In recent years, suitcases have been reduced in weight by using lightweight materials such as polycarbonate for the lid-side shell and the body-side shell, which are the case body, but for further weight reduction, the area around the joint between the lid-side shell and the body-side shell The zipper is provided at the mating part of the lid side shell and the body side shell in place of the shutter lock for sealing the lid side shell and the body side shell that will be abolished. There is one that seals the side shell and the body side shell.

  Since the frame is a solid material mainly made of metal or hard resin, the suitcase can be considerably lightened by eliminating the frame. However, however, the joining part of the lid side shell and the body side shell The strength of the caster is unavoidable, especially when the suitcase is caster-moved, such as the caster disposition surface that has bent outward due to the weight of the luggage in the case, that is, the case surface or zipper that becomes the bottom when the caster moves The element part was rubbed against the ground, and these parts were scratched or even cracked, making it impossible to continue using the suitcase.

JP 2011-15775 A

  An object of the present invention is to provide a suitcase capable of greatly reducing at least the deflection generated on the caster mounting surface due to the weight of the load in the case.

  In order to solve the above-described problem, a suitcase according to the present invention is provided with a zipper attached to a mating portion of a lid-side shell and a body-side shell via a soft synthetic resin member, and at least on a caster mounting surface. An arcuate concave depression is formed in the direction.

  The lid side shell and the body side shell, which are the main body of the suitcase, are connected by an opening / closing means such as a hinge, and the zipper tape part is attached to each opening edge of the lid side shell and the body side shell via a soft synthetic resin member. It is attached.

  The soft synthetic resin member is, for example, an elastomer, but a suitable soft synthetic resin member is selected according to the shell material, the material used for the zipper tape, and the method of attaching to the shell. Can be used.

  And, at least on the caster mounting surface, an arcuate concave depression is formed in the depth direction, and at least the caster mounting surface is the side of the lid that faces the ground when the suitcase is moved by the caster. In addition to the surfaces of the shell and the body-side shell, the surfaces of the lid-side shell and the body-side shell that face the ground when the suitcase is placed by legs provided at appropriate positions are included.

  The depth direction refers to the direction inside the case with respect to the case surface serving as the bottom, and at least the case surface in a range where bending can occur is formed in a concave shape in an arc shape, that is, curved inward in the case. . Also, the direction of the arc is preferably substantially parallel to the soft synthetic resin member provided at the mating portion of the lid side shell and the body side shell.

  Further, depending on the size of the suitcase, a flat portion may be provided along the soft synthetic resin member between the soft synthetic resin member and the recessed depressed portion. The strength in the vicinity of the mating portion of the shell can be increased, and the occurrence of bending can be greatly suppressed.

  In addition, when the strength in the vicinity of the mating portion of the lid-side shell and the body-side shell is further increased, a sine waveform or rectangular wave-shaped formation portion orthogonal to the soft synthetic resin member is formed on a part or all of the flat portion. May be provided.

  According to the suitcase of the present invention, at least in normal use, the caster disposition surface does not bend due to the weight of the luggage in the case, so that the case surface or the lid side shell and the body side shell are aligned. The element part of the zipper provided in the part is not rubbed against the ground, and the caster of the suitcase can be moved with peace of mind.

  Therefore, you don't have to worry about moving the suitcase casters at your travel destination, so you can fully enjoy the surrounding scenery even if you walk around the suitcase, and you can easily grasp the surrounding situation. You can walk safely and happily.

  In addition, since damage to the case surface and the zipper element, which is fatal to continue using the suitcase, can be equal to zero in normal use, the favorite suitcase can be used for a longer time.

  Furthermore, since the bending of the case surface can be suppressed without providing a reinforcing member, the suitcase can be immediately applied to a frameless and lightweight suitcase without increasing the weight of the suitcase.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a suitcase according to the present invention will be described in detail based on specific examples shown in the accompanying drawings.

  As shown in FIG. 1, the suitcase 1 has a zipper 6 attached to a mating portion 4 of a lid-side shell 2 and a body-side shell 3 via a soft synthetic resin member 5. The lid-side shell 2 and the body-side shell 3 that are openably / closably connected by an opening / closing means such as (not shown) can be opened or closed.

  As shown in FIGS. 2 and 3, at least the case side 8 of the lid side shell 2 and the body side shell 3 that become the bottom of the suitcase 1 when moving using the caster 7, in the depth direction, that is, inward of the case An arcuate recess 9 is formed.

  Further, in this embodiment, a flat portion 10 is provided between the soft synthetic resin member 5 and the concave depression 9, and the concave surface of the concave depression 9 is formed from the end of the flat portion 10 on the concave depression 9 side. The falling wall 11 is formed.

  Hereinafter, the operation of the suitcase according to the present invention configured as described above will be described.

  As shown in FIG. 2, when the suitcase 1 is placed on the ground 12 by the casters 7 or when the suitcase 1 is moved on the ground 12 by the handle 13, the weight of the luggage in the case is in the same state. Hangs on the case surface 8 of the lid-side shell 2 and the body-side shell 3, which are the bottom of the suitcase 1.

  Then, the outer curved surface of the concave depression 9 formed on the case surface 8 of the lid-side shell 2 and the body shell 3 receives the weight (heavy pressure) of the load, and this heavy pressure is applied to the casters 7 side of the concave depression 9. It is distributed and hung on the curved base (case surface 8).

  That is, by providing the recessed depression 9 on the case surface 8 of the lid-side shell 2 and the body-side shell 3, the heavy pressure applied to the case surface 8, which is the bottom of the suitcase 1, The curved base portion (case surface 8) of the concave depression 9 has sufficient strength because it is dispersed on the case surface 8), and is sufficient for the heavy pressure of the load. Endure.

  In addition, the suitcase 1 of the present embodiment has a falling wall 11 that extends from the end of the flat portion 10 provided between the soft synthetic resin member 5 and the recessed portion 9 to the recessed surface of the recessed portion 9. Therefore, the falling wall 11 suppresses the bending that is likely to occur at the mating portion 4 of the lid-side shell 2 and the body-side shell 3.

  Further, in the case of a small suitcase in which the influence of the weight increase is small, the inner surface of the case surface 8 is changed to the arcuate recess 9 formed on the case surface 8 of the lid side shell 2 and the body side shell 3. An arch-shaped member may be provided. The arch-shaped member is preferably provided substantially parallel to the soft synthetic resin member provided at the joint portion of the lid-side shell and the body-side shell with both curved bases fixed to the case surface 8.
