DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage case partitioning device having an improved partition plate mounting structure.

[0002]

2. Description of the Related Art Conventionally, various article storage cases such as a floppy case for storing a large number of floppy disks in an upright state, an accessory case for storing office accessories, and a clothing case for folding and storing clothes, As a partitioning device for partitioning the article storage space in the case into a plurality, a partition plate is detachably mounted between left and right side walls of the case, and the partition space can be arbitrarily changed by adjusting the mounting position or the number of the partition plates. This is well known.

Conventionally, as a means for mounting the partition plate, a plurality of partition plate mounting holes are provided at predetermined intervals in the front-rear direction on the left and right sides or at the center of the bottom wall of the case, and the lower end of the partition plate faces downward. A means is provided for inserting the projecting mounting legs into the partition plate mounting holes.

[0004]

However, according to this structure, the pitch of the partition plate mounting holes cannot be made too small because the strength of the case bottom wall in which the partition plate mounting holes are provided must be maintained.

[0005] Therefore, since the position of the partition plate can be adjusted only roughly at a large pitch, when the articles are sorted and stored in each of the partitions partitioned by the partition plate, a necessary partition and an actual partition are stored. There is a difference from the compartment.

In particular, in the case of a floppy case, it is desired to adjust the division in units of one disk, while the pitch of the position adjustment of the partition plate is much larger than this.
There has been such a problem that the difference is increased and the storage efficiency is deteriorated.

Accordingly, the present invention provides a partitioning device for a floppy storage case that can adjust the position of a partition plate at a fine pitch corresponding to a required section.

[0008]

According to the first aspect of the present invention, left and right side walls for regulating the position of a stored article in the left-right direction, a bottom wall for supporting the article, and a partition plate for partitioning the article storage space into front and rear. In the article storage case provided with the partition plate, a projection protruding laterally is provided on both left and right sides of a lower end portion of the partition plate, while a projection of the partition plate is inserted on inner surfaces of lower end portions of the left and right side walls. A mounting groove is provided in the front-rear direction, and a large number of engaging teeth for regulating the position of the projection in the front-rear direction are provided continuously on the upper surface of the partition plate mounting groove in a saw-tooth shape.

According to a second aspect of the present invention, in the configuration of the first aspect, the partition plate mounting groove is formed as a gap between the lower end surfaces of the left and right side walls and the upper surface of the bottom wall.

According to a third aspect of the present invention, in the configuration of the first or second aspect, the projection of the partition plate is formed in a hemispherical shape.

According to a fourth aspect of the present invention, in the configuration according to any one of the first to third aspects, both front and rear side surfaces of the engaging teeth are formed as arcuate concave surfaces.

[0012]

According to the above construction, since the projection of the partition plate is inserted between the engaging teeth of the partition plate mounting groove and the partition plate is mounted, the position of the partition plate can be adjusted at the pitch of the engaging teeth. . That is, the mounting position of the partition plate can be selected and adjusted at a fine pitch (almost stepless) in the front-rear direction.

Therefore, the article storage space can be accurately partitioned as desired, and the space can be used efficiently without waste.

According to the second aspect of the present invention, since the partition plate mounting groove is formed as a gap between the lower end surfaces of the left and right side walls and the upper surface of the bottom wall, the mounting groove is formed in the left and right side wall itself. Unlike the case in which it is provided, the width of the mounting groove can be expanded by elastic deformation of the bottom wall. For this reason, the partition plate can be easily and easily attached and detached by pushing the bottom wall downward and inserting and removing the projection of the partition plate with respect to the mounting groove.

Further, according to the third aspect of the present invention, the projections of the partition plate are formed in a hemispherical shape, and the front and rear surfaces of the engaging teeth are formed as concave surfaces on an arc. The passage resistance is small, and the attachment and detachment of the partition plate and the position adjustment operation can be performed more smoothly.
