Article support rack

1. An article support rack having a plurality of levels of rack portions so that the rack portions are arranged one rack portion over another along a vertical direction, each rack portion being capable of supporting a plurality of articles with the articles arranged one adjacent to another along a first direction parallel to a horizontal plane, the article support rack comprising:

shelf rows each of which is provided to a corresponding one of the plurality of levels of rack portions and is configured to support articles from below with each of the plurality of levels of rack portions including a shelf row; and

shelf support members which support the shelf rows;

wherein each of the shelf rows includes one or more main body portions each of which is plate-shaped and oriented parallel to a horizontal plane, and rib portions each of which projects downward with respect to a corresponding one of the one or more main body portions of one of the shelf rows that the rib portion is a portion of, each of the rib portions extending from a corresponding one of the shelf support members in a front-face side direction which is one direction along a second direction which is perpendicular to the first direction as seen along a vertical direction, wherein each of the shelf rows is supported by the shelf support members in a cantilever-fashion from a back-face side of the each of the shelf rows where the back-face side being a side corresponding to a back-face side direction, which is a direction along the second direction that is opposite from the front-face side direction,

wherein outer surfaces of each article include maximum width areas in which a dimension along a lateral width direction of the article is greatest, and width decreasing areas in which a dimension along the lateral width direction of the article decreases toward a depth direction side end of the article with the depth direction being a direction perpendicular to the lateral width direction,

wherein each of the shelf rows is configured to support the articles with each article being so oriented that the depth direction thereof points toward the back-face side,

wherein each of the rib portions is so located, in plan view, to be between two lower level articles that are adjacent to each other along the first direction and are supported by a lower level shelf row which is one of the shelf rows that is located one level below a shelf row to which the rib portion is provided, when such two lower level articles are so supported,

wherein each of the rib portions has a first portion so located to be higher than one of the lower level articles which is an article supported by the lower level shelf row, and a second portion located lower than the first portion, when the one of the lower level articles is so supported, and

wherein each second portion is so located that the second portion does not overlap with the maximum width areas of the one of the lower level articles as seen along the first direction and is so located that, as seen along the first direction, the second portion overlaps with at least one of (a) the width decreasing areas and (b) any portion or portions that are located to the back-face side of the width decreasing areas, of the one of the lower level article when supported.

2. The article support rack as defined in claim 1 , wherein in addition to the one or more main body portions, each of the shelf rows has brackets which support the one or more main body portions from below with each bracket attached to a corresponding one of the shelf support members,

wherein each of the brackets has a corresponding one of the rib portions and an upper-face-side plate-shaped portion which is oriented parallel to a horizontal plane and is connected to an upper end of the corresponding one of the rib portions, and

wherein each of the one or more main body portions is fixed to corresponding ones of the brackets with the main body portion in contact, from above, with the upper-face-side plate-shaped portions of the corresponding ones of the brackets.

3. The article support rack as defined in claim 2 , wherein each of the brackets has a back-face-side plate-shaped portion which is oriented parallel to a vertical plane and is connected to an end portion, on the back-face side, of a corresponding one of the rib portions, and

wherein the back-face-side plate-shaped portion is fixed to a corresponding one of the shelf support members with the back-face-side plate-shaped portion in contact with the corresponding one of the shelf support members from the front-face side, which is a side corresponding to the front-face side direction.

4. The article support rack as defined in claim 1 , wherein each of the shelf rows includes fastened portions each of which is fixed to a corresponding one of the shelf support members, and

wherein each of the shelf support members has fitting-engaged portions each of which is in fitting engagement with a corresponding one of the fastened portions.

5. The article support rack as defined in claim 1 , wherein each second portion is so located to be spaced apart from any outer surface of the lower level article by a distance greater than or equal to a set distance.
