FIG. 8 is an enlarged view showing a closed state of the column door. In these drawings, it is assumed that the left column door is in a closed state.

  As shown in FIGS. 1 to 3, the product storage rack 1 according to this embodiment includes a pair of left and right side plates 2 and 2, and an upper frame 3 and a lower frame 4 that connect the side plates 2 and 2 to each other. This constitutes a rectangular parallelepiped housing having an opening. The inside of the product storage rack 1 is divided into two columns 6 and 6 by a partition plate 5, and each column 6 and 6 stores a chain elevator type product storage device 7 as shown in FIG. It is.

  As shown in FIG. 3, the chain elevator type product storage device 7 has sprockets 71 and 72 arranged at the upper and lower portions, and a plastic chain 73 is installed between the sprockets 71 and 72. It is. A product shelf 75 is attached to the plastic chain 73 via an attachment 74 at every predetermined attachment pitch. Then, by circulating this plastic chain 73 by a motor (not shown), the product shelf 75 moves downward, and the product S mounted on the product shelf 75 is carried out from the lower part of the product storage rack 1. And the goods shelf 75 which carried out the goods moves upwards after being folded. According to such a chain elevator type product storage device 7, the product S and the product S are not in direct contact with each other in the stored state, and the mounting pitch of the product shelf 75 is changed to compare from a small product. It can store even large items.

  A column door 8 is provided at the front opening of the product storage rack 1 to regulate the front surface of the product S stored in each column 6. The column door 8 is attached to each side plate 2 and can be opened left and right (so-called double door opening). Here, since the left column door 8 and the right column door 8 are bilaterally symmetric, the right column door 8 will be described as an example, and the description of the left column door 8 will be omitted.

  On the right side of the right column door 8 (hereinafter, referred to as the support side in the right column door 8), a hinge portion 81 extending laterally is formed on the upper, central and lower side edge portions 8A. These hinge portions 81 are inserted into wide rectangular door support holes 21 formed in the upper, central and lower portions of the front edge side of the right side plate 2 and then from the front edge of the side plate 2 to the side edge of the door support hole. It is bent in a cylindrical shape so as to be wound around the door support shaft 22 formed by being bent in a cylindrical shape. Therefore, the column door 8 can be opened and closed in the left-right direction, and can be raised and lowered in the up-down direction. Further, the side edge portion 8A on the support side of the column door 8 is hemmed and bent on the near side except for the portion where the hinge portion 81 is formed. Hemming bending is a bending process of folding back 180 degrees, and the side edge portion on the support side is doubled to increase the thickness and strength.

  The upper edge portion 8B of the right column door 8 extends to the back by being bent into an L shape, and the extended portion overlaps the upper surface of the opening edge portion of the upper frame 3 when the column door is closed. It has become. Further, the locking claw 82 is formed by bending the open side of the portion extending in the back further downward. When the column door 8 is lowered by closing the column door 8, the locking claw 82 is inserted into a rectangular locking hole 31 formed on the upper surface of the opening edge of the upper frame 3 to prevent the column door 8 from being opened. Possible (locked state).

The side edge portion 8C on the left side of the right column door 8 (hereinafter referred to as the open side in the right column door 8 ) is hemmed and bent on the front side in the same manner as the side edge on the support side. Therefore, similarly to the side edge portion 8A on the support side, the side edge portion 8C on the open side is doubled, increasing the thickness and strength.

  The lower edge portion 8D of the right column door 8 is hemmed on the front side, and is formed so that its end surface gradually rises from the support side toward the open side. Specifically, the column door 8 is inclined from the support side toward the open side so as to have an inclination angle of 2 degrees with respect to the horizontal direction (see FIG. 7).

  A sill portion 41 and a locking groove 42 are formed at the opening edge of the lower frame 4. The sill portion 41 is a plate-like portion subjected to hemming bending, and the upper surface of the sill portion 41 can support the column door 8 from the open state to just before closing. Further, the locking groove 42 is formed along the sill portion 41, and when the column door 8 is closed, the lower edge portion 8D of the column door 8 can sink. When the lower edge portion 8D of the column door 8 sinks into the locking groove 42, the entire column door 8 is lowered. Further, the lower edge portion 8D of the settled column door 8 is in contact with and engaged with the sill portion 41 of the lower frame 4 and can prevent the column door 8 from being opened (locked state).

  When the column door 8 of the commodity storage rack 1 according to the above-described embodiment is in an open state as shown in FIG. 6, the hinge portion 81 of the column door 8 is supported by the door support shaft 22 and the lower edge. The support side of the portion 8D is supported on the upper surface of the sill portion 41 of the lower frame 4. When the column door 8 is closed from the open state, the hinge portion 81 is supported on the door support shaft 22 and the support side of the lower edge portion 8D is supported on the upper surface of the sill portion of the lower frame 4 as shown in FIG. In addition, the column door 8 is rotated in the closing direction to the state immediately before being closed. At this time (a state immediately before the column door is closed), there is a gap that gradually expands from the support side to the open side between the lower edge portion 8D of the column door 8 and the upper surface of the sill portion 41 of the lower frame 4. (See FIG. 7).

  When the column door 8 is further closed, the column door 8 is further rotated and the lower edge portion 8D of the column door 8 reaches the locking groove 42 of the lower frame 4. Then, as shown in FIG. 8, the lower edge portion 8 </ b> D of the column door 8 settles in the locking groove 42, and the locking claw 82 of the column door 8 is inserted into the locking hole 31. Thus, when the lower edge portion 8D of the column door 8 sinks into the locking groove 42 of the lower frame 4, the lower edge portion 8D of the column door 8 comes into contact with and engages with the sill portion 41 of the lower frame 4, and the column door. Even if 8 is pulled to the near side, it does not open (locked state).

  When the column door 8 is opened from this locked state, the column door 8 is lifted upward to cause the lower edge portion 8D of the column door 8 to escape from the locking groove 42 of the lower frame 4 and After releasing the contact engagement state between the edge portion 8D and the sill portion 41 of the lower frame 4, it may be pulled to the near side.

  Since the commodity storage rack 1 according to the above-described embodiment is formed so that the lower edge portion 8D of the column door 8 is inclined so as to gradually rise from the support side to the open side, the column door 8 is opened. The opening side of the lower edge portion 8D of the column door 8 is not caught by the sill portion 41 of the lower frame 4 until the state immediately before closing, so that the column door 8 can be smoothly closed (locked).

  As described above, the chain elevator type product storage rack 1 has been described as an embodiment of the present invention. However, the present invention is not limited to the chain elevator type product storage rack, and the present invention is a direct stack type product storage rack. It is also applicable to.

  As described above, the product storage rack according to the present invention is useful for a product storage rack having a column door, and is particularly suitable for a product storage rack that locks the column door at a closed position by a closing operation.
