  Further, cylindrical caps are attached to both ends of the rear frame member 22a as engaging portions 23a, and engage with the engaged portion 13a of the rear column 13 at a position 25 cm above the position of the frame body 20 so as to be horizontal. It is attached.

The left and right sides of the upper rear frame member 22a and the left and right side frame members 24 arranged below are connected to each other at right angles in the left and right directions using two connection pipe bodies 30a of the present invention. This pipe connection body 30 a has one joint structure, and a pipe body 31 having a length of 226 mm is attached to both ends of the joint portion 33, and a clamp body 41 is attached to the outside of the pipe body 31.

The rod-like body 25 is installed between the ends of the horizontal pipe joint portions 33 of the two left and right pipe coupling bodies 30a, and fastened by the rod-like clamp body 26. Thus, a strong framework is formed, and the rectangular plate 28 is placed on the rod-like body 25 and the rear frame member 22a. Here, the right side of the rectangular plate 28 is cut out for illustration.
As a result, the platform-like article placement section, which had previously been required to assemble two frames, is simply assembled, and the appearance is clean.

  In the embodiment described above, the area of the region surrounded by the U-shaped frame is approximately 75 cm square, a rod-shaped member is installed between the frames, and a frame is arranged between the frame members and the rod-shaped members. The square plate 27 and the rectangular plate 28 are attached, the rectangular plate has a planar size of 75 cm in width and 25 cm in depth, and the square plate is an example having a planar size of 25 cm square, and an area region surrounded by the frame body is A square plate will be described as a unit block of each lattice in the form of a lattice of 3 in length and 3 in width, and the rectangular plate has a configuration having an area three times that of the square plate.

In this unit block, the square area may be in the form of a grid of 2 in the vertical direction and 2 in the horizontal direction, or may be in the form of a grid of 4 in the vertical direction and 4 in the horizontal direction. Of course, you may make it 5 or more square lattice shape.
For this purpose, a frame arrangement is configured with a rod-like body installed on a U-shaped frame, and a first distance between the side frame members arranged in parallel is maintained, and the frames are bridged orthogonally between the side frame members. A square plate can be arranged by setting the distance between the two rods to a substantially distance obtained by dividing the distance between the side frame members by an integer of 2 or more.

  The approximate distance is a structure in which a rod is attached to the inside of the edge of the square plate when attaching the square plates. Therefore, in order to actually arrange the 3 × 3 square plates in the frame region, 3 between the frames. This is because it is necessary to arrange two rods close to each other at equal positions. Strictly speaking, the distance is obtained by subtracting the thickness of the edge of the rectangular plate and the radius of the rod from the distance obtained by dividing the distance between the frame members by an integer of 2 or more.

  By adopting this configuration, an area where there is no square plate becomes an article dropping area, and an area where the square plate is present can place an article or place the article in a state where it can be slipped by being inclined.

  As described above, the present invention has been described by the preferred embodiments of the present invention. It will be apparent that various modifications and changes may be made to these embodiments without departing from the broad spirit and scope of the invention as defined in the claims. In other words, the present invention should not be construed as being limited by the details of the specific examples and the accompanying drawings.
