It is a front view which shows the state in the middle of operation. In the figure, the same reference numerals and symbols as those of the above-mentioned conventional example indicate the same or corresponding components as those of the above-mentioned conventional example.

As shown in the drawing, in the receiving post frame for a postcard sorting box of this embodiment, four columns 10 are provided at four corners in the front, rear, left, and right in an open-leg state with a predetermined inclination angle. The upper ends 11 of the columns 10 are connected by a hinge member 30 in such a manner that they can be opened and closed in the front-rear direction, and the lower ends 12 of the columns 10 are equipped with non-slip terminal members 61. A plurality of arm members 20 are attached to the intermediate portion 13 of each of the columns 10 at predetermined intervals. Each of these columns 10 is appropriately connected by a foldable connecting pipe 40 which is a rotation restricting member of the present embodiment and has a foldable structure or a foldable connecting pipe 400 which is a parallel position setting member of the present embodiment. Has been done. That is, the foldable connection pipe 400 connects the front and rear struts 10 of the four struts 10 with the hinge member 30 and the front and rear connection pipes 41, and connects the left and right struts 10 with the left and right horizontal connection pipes 42 and the left and right oblique connections. It is connected by a pipe 43. In particular,
In this embodiment, the left and right oblique connection pipes 43 have opposite inclinations on the front and back sides of the postcard sorting box receiving rack, but the left and right oblique connecting pipes 43 are on the front side of the postcard sorting box receiving rack. The same inclination may be applied to the back side and the back side. In this embodiment as well, the postcard sorting boxes 6 can be mounted on the arm members 20, respectively.

Further, in order to store the receiving post frame for the postcard sorting box, first, as shown in FIG. 3, each arm member 20 is folded and the front and rear connecting pipes 41 of the folding connecting pipe 40 are folded. Thus, the front and rear struts 10 are closed with the hinge member 30 as a fulcrum. When each arm member 20 is folded, the bottom surface of each arm member 20 becomes parallel to the column 10.
Then, as shown in FIG. 4, the left and right horizontal connecting pipes 42 and the left and right oblique connecting pipes 43 of the folding connecting pipe 400 are folded, respectively, and the left and right support columns 10 are brought close together. In this way, the four columns 10 on the front, rear, left, and right are bundled into a substantially rod shape for storage.

Next, each part of the postcard sorting box receiving rack frame will be described in detail with reference to the drawings. First, the arm member 2
0 and its disposition will be described. 5 is an enlarged front view showing part A of the postcard sorting box receiving rack of FIG. 1, and FIG. 6 is a similar view of the postcard sorting box receiving rack of FIG.
It is an enlarged plan view showing a portion.

As shown in FIGS. 5 and 6, the column 10 has a cross-sectional shape in which a rectangular tube-shaped portion 14 and two U-shaped portions 15 and 16 are joined together. The column 10 is formed by extruding aluminum. Is produced as. The arm member 20 is attached to the square tubular portion 14 of the column 10 in a foldable state. The arm member 20 has a tip claw 21 formed at the tip, a receiving arm 22 for supporting the postcard sorting box 6,
It is composed of a joint portion 23 for attaching to the column 10,

Therefore, when the foldable connecting pipes 40, 400 are completely folded, they are housed inside the U-shaped portion 16 of the support column 10.

As described above, the postcard sorting box receiving rack of the present embodiment restrains rotation exceeding a predetermined rotation angle,
Further, it has a rotation restricting member including a foldable connecting pipe 40 or a foldable front-rear connecting leg 70 that allows a rotation of a predetermined rotation angle or less, and is rotatable around a fulcrum of the hinge member 30. Four columns 1 with two pairs connected to each other facing each other
Of the 0 and the four columns 10, two columns 10 facing each other on the side not pivotally connected to each other around the fulcrum of the hinge member 30 are set as a pair, and the parallel distance between the two columns is predetermined. And the parallel position setting member composed of the foldable connection pipe 400 that minimizes the parallel distance between the two and the hinge member 30 is allowed to rotate about the fulcrum of the hinge member 30. An arm member 20 is provided outside the turning angle of the pair of columns 10 at a predetermined interval and receives the postcard sorting box 6.

Therefore, the rotation restricting member composed of the foldable connecting pipe 40 or the foldable front and rear connecting legs 70 is restrained from rotating beyond a predetermined rotating angle, and is not supported by the fulcrum. Folding type connecting pipe 40
The parallel position setting member of 0 separates the parallel distance between the arm member 20 and the arm member 20 by a predetermined distance.
Receive the postcard sorting box in a stable condition at. And
Two pairs, which are rotatably connected about a fulcrum by a rotation restricting member composed of a foldable connection pipe 40 or a foldable front-rear connection leg 70, are brought closer to each other by rotation of columns supported by the fulcrum. , And of the four columns that are facing each other,
The two columns 10 facing each other on the side not pivotally connected to each other about the fulcrum are set to a compact storage state by setting the parallel distance between the two columns to a minimum distance.

Therefore, the four supporting columns 10 are formed by folding the rotation restricting member composed of the foldable connecting pipe 40 or the foldable front and rear connecting legs 70 and the parallel position setting member composed of the foldable connecting pipe 40. It can be housed inside and the four columns 10 can be bundled into a single rod-shaped body. Moreover, in the present embodiment, since the rod-shaped bodies can be bound together by the band 80, the handling at the time of movement for storage is further facilitated, the storage space when not in use is reduced, and the storability is improved.

Further, since the support column 10 is an aluminum extrusion molded product and the arm member 20 is a synthetic resin integrated molded product, the overall weight is lighter than that of an iron product.
Since it is easy to handle, and the end portion of the arm member 20 can be easily treated, there is no fear that an operator will catch clothes.

Further, since the arm member 20 similar to that of the first embodiment is attached to each of the columns 10, when the postcard sorting box 6 is placed on this arm member 20, the postcard sorting box 6 is Hard to drop. Further, since the folded arm member 20 does not unfold freely and the unfolded arm member 20 does not fold unintentionally, it is convenient for use and storage.

By the way, in the above-mentioned first and second embodiments, the column 10 is formed by the rectangular tubular portion 14 and the U-shaped portions 15, 1.
Although the cross-sectional shape of 6 has been described, it is inevitable that
The sectional shape is not limited to this. However, it is superior in terms of storability that the folding type connecting pipes 40, 400 and the folding front and rear connecting legs 70 have a shape that can be stored in the support column 10.

Incidentally, the folding type connecting pipe 40 of the above embodiment.
Alternatively, the rotation restricting member including the folding front and rear connecting legs 70 and the parallel position setting member including the folding connecting pipes 400 may be the folding connecting pipes 40 and 400 or the folding front and rear connecting legs 7.
The present invention is not limited to 0, and when the present invention is carried out,
The rotation restricting member has a function of restraining rotation of a pair pivotally connected about a fulcrum beyond a predetermined rotation angle and permitting rotation below the predetermined rotation angle. If you have. Further, in the parallel position setting member, the two facing sides on the side not rotatably connected to each other around the fulcrum are opposed.
It suffices that the columns of the books are paired, the parallel distance between them is restricted to a predetermined distance, and the parallel distance between them is set to the minimum distance.

[0056]

As described above, in the postcard assortment box receiving rack of the present invention, the rotation restricting member restrains the rotation exceeding the predetermined rotation angle, and is supported at its fulcrum. By separating the parallel columns between the unsupported columns by a parallel position setting member, a predetermined distance
The arm member stably receives the postcard sorting box,
The standing condition is stable. Then, of the four columns which are made to come close to each other by the rotation of the columns supported by the fulcrum, and which are opposed to each other, the two pairs rotatably connected about the fulcrum by the rotation restricting member By setting the parallel distance between the two supporting columns, which are opposite to each other and are not rotatably connected to each other around the fulcrum, to be the minimum distance, the column can be made compact and stored.

Therefore, the rotation restricting member and the parallel position setting member are housed in the four columns in a folded state, respectively.
You can bundle the columns of a book into a rod-shaped body,
Handling during transportation for storage is further facilitated, storage space when not in use is reduced, and storability is improved.
