2. Description of the Related Art In a prefabricated article mounting shelf having such a structure, it is necessary to prevent the struts from wobbling or rattling when the struts are inserted into the strut holding members. As shown in FIG.
A substantially V-shaped notch 12a is provided at the upper end of the support 3, and a V-shaped protrusion 12b engaged with the V-shaped notch 12a is
When the support 3 is inserted into the support holding member 2A,
The projection 12b on the column 3 side is the notch 1 on the column holding member 2A side.
2a, it is known that the column 3 is prevented from moving downward with respect to the column holding member 2A, and the lower end of the column 3 contacts the bottom plate of the column holding member 2A. .

[0003]

According to this conventional structure, it is possible to reduce the wobbling of the column 3 with respect to the column holding member 2A by the engagement between the notch 12a and the projection 12b. There was still room for improvement. That is, in order to smoothly insert and remove the column 3 with respect to the column holding member 2A, it is necessary to make the outer dimension of the column 3 slightly smaller than the inner dimension of the column holding member 2A. Therefore, when the notch 12a and the protrusion 12b are engaged with each other, the support 3
12 swings left and right and back and forth as indicated by the arrows in FIG. 12, and the swing causes rattling of the intermediate shelf attached to the column 3, and the article is placed on the intermediate shelf. Has not been able to be stably placed.

The present invention focuses on such a conventional problem, and an object of the present invention is to attach a support column to a support column while allowing the support column to be smoothly inserted into and removed from the support column. An object of the present invention is to provide an assembling-type article mounting shelf which can insert and hold a support post in a state in which the support post does not rattle when inserted.

[0005]

According to the first aspect of the present invention, when a support is inserted into a support holding member provided on a base, either the support or the support is used. Since the notch provided on one side and the projection provided on the other side engage with each other, engagement means for preventing the column from moving downward with respect to the column holding member is provided on the column holding member and the column. By this engagement means, the column is prevented from moving downward, and to some extent, the column is prevented from wobbling or rattling with respect to the column holding member. And
In the engagement state of the engagement means, the engagement type swing prevention means for preventing the lower portion of the support from swinging about the engagement means, Since the engagement by the engagement type rocking prevention means is provided in a deepened state, the rocking of the lower portion of the column is also prevented by the engagement type rocking prevention means. As a result, the engagement means and the engagement type rocking prevention means are provided. And each column is inserted and held in the column holding member with little rattling. Therefore, even if the outer dimension of the column is slightly smaller than the inner dimension of the column holding member, the column is attached to each column holding member so that the column can be smoothly inserted and removed with respect to each column holding member. It can be securely held.

According to the second aspect of the present invention, the engaging means includes a substantially V-shaped notch provided at the upper end of the column holding member, and a substantially V-shaped notch provided at the column. Therefore, while having a relatively simple configuration, it is easy to engage the projection on the column side with the notch on the column holding member side. Since it is composed of a substantially V-shaped bottom plate provided at the lower end of the member and a lower end portion of a column contacting the bottom plate,
The engagement type rocking prevention means also has a simpler configuration, but by pressing the column downward, the engagement between the engagement means and the engagement type rocking prevention means can be acted on the side that deepens together. As a result, the more articles are placed on the intermediate shelf, the more surely the columns are held by the load of the articles.

According to the third aspect of the present invention, only one side of the bottom plate of the column holding member is integrally connected to the column holding member, and the bottom plate is centered on the connected one side. Are configured to be elastically deformable in the vertical direction, so that even if there is a slight manufacturing error in the positional relationship between the engagement means and the engagement type rocking prevention means, the manufacturing error is caused by the elastic deformation of the bottom plate. Will be absorbed and, as a result,
Strict precision is not required for the engagement means and the engagement type rocking means, and the manufacture becomes easy.

According to the fourth aspect of the present invention, since the V-shaped side surface of the bottom plate is open, when applying rust preventive, paint, or the like to the support member by dipping or the like,
The coating operation is facilitated, and it is also effective in protecting the inside of the support member. In other words, when paint or the like is applied to the column holding member, if more paint than necessary is left inside and solidifies, the insertion of the column will be hindered,
Since the lateral side surface of the V-shaped bottom plate is opened and flows out, there is no need to discharge extra paint or the like after completion of the application work, and the work of applying the paint or the like becomes easy. Similarly, even if this article mounting shelf is installed outdoors and rainwater intrudes into the support member, or if a potted flower or the like is placed and watering on the flower enters the support member, However, the intruded water naturally flows out, and an effect of preventing rust inside the support member can be expected.
