Subassemblages of furniture can be built from rod elements, beam elements, boards and panels. Usually, they are connected in a permanent and inseparable way, although in the group of furniture for disassembly there are many subassemblages connected using connectors which ensure freedom in assembling and disassembling them. They occur as 2-D and 3-D structures. The most common subassemblages can include drawers, including cases, doors of a frame panel construction, socle and upholstery frames.
Drawers, although they have a similar purpose, can be made both from wooden and wood-based materials, as well as from metal and plastic. Several types of drawers have been shown in Fig. 4.52.
A frame panel door is a typical subassemblage of furniture produced with the great participation of wood. The frame construction is usually made up of beam elements connected with dowels, simple single plugs or splines. The panel can constitute (Fig. 4.53) a milled MDF board, glass, milled wooden board, stained glass and steel sheet with holes.
Socles perform the function of frames of case or upholstered furniture supporting the entire construction. Their composition can consist of wooden or metal rod elements or also of boards and beam elements (Fig. 4.54).
The function supporting the bed or seat in upholstered furniture is performed by upholstery frames. Typical constructions are upholstery frames shown in Fig. 4.55. Wooden bearing structures are made mainly of coniferous or deciduous lumber. As it can be seen, the bearing structures are frames, to which upholstery layers are mounted or applied and/or handles, backrests and seats are attached.
