Description of the Related Art Conventionally, relatively inexpensive multi-stage shelves and multi-stage drawers made of synthetic resin, which can be assembled by inserting a separate pillar into a pillar fitting hole provided in a pillar mounting member such as a shelf board, are as follows.
In order to simplify the assembly and reduce the cost, many of them do not have a pillar retaining mechanism. However, such a device has a drawback that the column comes off from the column insertion hole when the whole is lifted by holding the upper shelf or the like. In addition, with a drawer attached, release the hand until it is about to drop out of the drawer that is full of contents, and the drawer is supported by the lower shelf at the rear end side, and the front end side tends to fall down by its own weight Therefore, the drawer acts as a lever with the portion supported by the shelf as a fulcrum, and the rear end of the drawer attempts to push up the upper shelf with strong force. For this reason, those without a reliable pillar retaining mechanism have a drawback that the upper shelf plate is pushed up and the pillar comes off from the pillar fitting hole.

A slit 30 may be provided. When the slit 30 is provided, when the fitting portion 3a of the pillar 1a is inserted into the pillar fitting hole of the same shelf plate as in the first embodiment, the engaging projection 6a is bent, as compared with the case where the slit 30 is not provided. With relatively light force, the fitting part 3
is pushed into the column fitting hole of the shelf, and the engaging projection 6 of the column 1a is pressed.
a can be engaged with the locking projection of the column fitting hole of the shelf board. Moreover, since the column 1a made of synthetic resin has the cross-sectional shape shown in FIG. 8, the mold used for molding has a complicated mold structure such as undercut as in the case of the first embodiment. Since there are no factors, the pillar 1a can be provided at a low cost, as in the case of the conventional one having no retaining mechanism, which can be produced with an inexpensive mold having a simple mechanism with few failures.

Thus, the height may be several millimeters higher than the vertical length of the engagement protrusion 6b. In this manner, the locking projections 12b in the column fitting holes 11b are engaged with the locking projections 12b engaged with the fitting portions 3b inserted from above and the fitting portions 3b inserted from below, as shown in FIG. Since the mating locking projections 12b can be arranged on the same parting line, mold processing of the shelf 10b is facilitated.

のものと同様に、柱を安価に提供することができる。As described above, in the pillar retaining mechanism of the present invention, the pillar is formed by opening the abdominal side of a synthetic resin rod-shaped pillar so that the horizontal cross section is substantially U-shaped or substantially semicircular. A pillar is formed so that the upper end and the lower end of the pillar are thinned to form a fitting portion, and an engaging protrusion is protruded on one of the left and right sides of the back surface or the side surface of the lower fitting portion. The upper and lower sides of the fitting part on either side of the left and right sides of the opposite side have an engaging projection at the upper end protruding, so the mold used for molding the pillar is a movable mold on the abdomen side of the pillar and fixed on the back side of the pillar If it is made into a mold, there is no factor that complicates the mold structure such as undercut, so it can be produced with an inexpensive mold with a simple mechanism with few failures, just like the conventional one without a retaining mechanism , Pillars can be provided at low cost.

い従来のものと同様に、棚板を安価に提供できる。Similarly, a pillar mounting member such as a synthetic resin shelf plate is provided with a through hole having a hole length about twice the length of the column fitting portion. A locking projection for the upper column, which engages with the engagement projection of the column inserted into the column insertion hole from above, is protruded toward one side of the inner surface of the column insertion hole, protrudes therefrom, and further, the engagement projection of the column inserted from below. The locking projection for the lower pillar, which engages with the upper pillar, is displaced from the locking projection for the upper pillar, and is shifted toward one side of the pillar fitting hole so as to protrude, so that the mold structure such as undercut becomes complicated. It can be produced with a simple mechanism with few factors and with few failures at a low cost, and a shelf plate can be provided at a low cost, similarly to the conventional one having no retaining mechanism.

らつくこともない優れた特長を合わせ持つ。Therefore, the pillar retaining mechanism of the present invention can be provided at low cost, similarly to the conventional one without the retaining mechanism, and can be assembled at the same time as the conventional one without the retaining mechanism. In addition, the column can be easily assembled simply by pushing the column into the column fitting hole of the column mounting member as it is, and the engaging projection of the column and the locking projection in the column fitting hole are engaged. Without falling off, furthermore, in the state where the pillar is fitted in the pillar fitting hole, in the vicinity of the hole edge of the pillar fitting hole, the outer diameter of the fitting portion of the pillar is substantially equal to the inner diameter of the pillar fitting hole, The column has excellent features that do not wobble with the column insertion hole.

け止め機構。An abdomen side of a synthetic resin rod-shaped column is opened to form a column having a substantially U-shaped or substantially semicircular arc-shaped cross section, and the upper end and the lower end of the column are narrowed and fitted. An engaging projection is provided on one of the left and right sides of the back or side of the lower end fitting portion, and the upper or lower end of the upper or lower fitting portion on the right or left side opposite to the lower end engaging projection is formed. And a through-hole-shaped column fitting hole having a hole length of about twice the length of the column fitting portion is provided in a column mounting member such as a synthetic resin shelf plate. A locking projection for the upper column, which engages with the engagement projection of the column inserted into the insertion hole from above, is arranged to protrude toward one side of the inner surface of the column insertion hole, and is further provided with an engagement projection of the column inserted from below. The locking projection for the lower pillar to be engaged is shifted from the locking projection for the upper pillar, and is shifted toward one side of the pillar fitting hole so as to protrude. A pillar retaining mechanism wherein the outer diameter of a column insertion portion is substantially equal to the inner diameter of the column insertion hole near the hole edge of the column insertion hole in a state of being fitted in the column insertion hole.
