ABSTRACT:
The present invention relates to a support structure for shelves suitable for ready changing of the height and the relative distance between individual shelf boards.
The support structure consists of vertical members adapted to be fastened to another vertical structure and of brackets adapted to be moved along the vertical members and to be held therein by frictional locking forces. Each vertical member has a uniform cross section in the shape of a rectangular, assymetrical channel comprising a web, a base flange provided with means for attaching it adjacent to a wall and an outer smaller-width flange provided along its outer with a re-entrant first guide parallel to the plane of the web. Inside the base flange is provided a second guide ridge, which faces the first guide ridge, but at a greater distance from the web than the first guide ridge. Each bracket is in the shape of a rigid angle plate having an inner end and an outer end, the inner end being positioned in a vertical member with its axis perpendicular to the plane of the base flange. The inner end comprises a vertical side plate of a height smaller than the bracket length which side plate is positioned outside and adjacent to the first guide ridge and parallel to the plane of the web, and a horizontal top plate of a width commensurate with the width of the outer flange. The top plate is divided by a cross-wise extending cut-out into an inner portion corresponding in shape and size to the inner space of the vertical member and into an outer portion distanced from the outer channel flange by a gap sufficient to allow tilting of the bracket in its vertical plane for the sidewise insertion of the inner portion into the inner space of the vertical member.
