8.2.1 Properties of Hyperelastic Polyurethane Foams Hyperelastic polyurethane foams are produced in the process of foaming polyure­thanes, with the use of cross-linkers, foaming agents and catalysts. In the produc­tion of these types of foams, it is important that after seasoning the block, a mechanical opening of closed pores takes place. Properly opened pores provide the […]

8.1 Stiffness and Strength of Upholstery Frames Frames of upholstery furniture belong to 3D structures, made of rails not lying in one plane, or 2D frames, but loaded with forces not lying in the system plane. (Fig. 8.1). The general principles and proceedings when solving frame 3D systems with the method of forces are the […]

• Natural and faux leather have a protective layer, but the use of inappropriate cleaning agents may cause damage to the cover. Therefore, under the threat of losing the warranty, the leathers have to be protected against solutions such as alkaline, acidic, etc. Instead, use solutions recommended by: (name of a company). • The frequency […]

The appropriate European norms define safety requirements for the use of furniture; however, they do not apply to the evaluation of the Fig. 7.79 Door of horizontal rotation axis with faultily working guides: a geometric scheme, […]

Doors of horizontal rotation axis are used in furniture fulfilling the function of bars and davenports. Their work tops in addition to mass and concentrated loads also shift the load equally distributed on the surface of the board. The strength of the door suspension is determined by the hinges mounted in horizontal partition of the […]

Criterion of strength for hinged doors of vertical rotation axis is the value of force resulting in breaking out of the hinge form the slot made in the particle board constituting side wall of the body. Distribution of internal forces acting on the hinge has been shown in Fig. 7.76. Taking into account the weight […]

Wall cupboards, especially bathroom and kitchen cupboards, are attached to the walls with the use of furniture handles screwed to the body, top or simultaneously to the top and side wall using screws (Fig. 7.75). Embedded in the wood, they should be screwed into the properly drilled holes with a diameter 2 mm smaller than […]
