PREFABRICATED HOLDER Russian patent published in 2022 - IPC A47G23/02 

FIELD: prefabricated holder.

SUBSTANCE: prefabricated holder consists of at least two vertical plates (A) and (B) with a silhouette with sidewalls (5) and a bridge (C) and perpendicularly connected to each other using mutually opposite recesses (1) in the area of the bridges so that the lower edges of the plates (A) and (B) are at the same level, and of at least one horizontal plate (E) that fixes the vertical plates (A) and (B) relative to each other and forms together with them a holder frame. The width of the recesses (1) of the plates (A) and (B) corresponds to the thickness of the plates themselves with the clearance necessary for a tight transverse connection. One of the vertical plates (A) or (B) has at least one notch (1) on the upper side of the bridge (C). The other vertical plate has at least one notch (1) on the bottom side of the bridge (C). Bridges (C) have studs (3). At least two studs (3) point upwards to provide a stud connection with a horizontal plate (E), which is fixed above the bridges (C) between the sidewalls (5) and has at least four grooves (4) for this, corresponding in terms of the location of the studs (3) on the bridges (C) of the vertical plates (A) and (B). The outer corners of all studs (3) and recesses (4) are rounded. The outer corners of the silhouette of the plates (A) and (B) are also rounded.

EFFECT: ensuring the minimum number of parts required for assembly, low weight, reliable use, stability on surfaces, interchangeability and complementarity of components, the ability to adapt the holder to different tasks, versatility and scalability.
