STUDY OF DEFORMATION RESISTANCE UNDER ADVERSE LOAD OF CONCEALED HINGES IN FURNITURE CONSTRUCTIONS

Abstract

Concealed hinges are most often used in modern furniture constructions. More and more hinge manufacturers are paying attention to this product group with the aim to improve strength and functional characteristics. To establish the suitability of these hinges for application in furniture constructions have been developed European standards. They however embedded only test in which the hinges have to pass or fail a certain test. No data for quantitative measurements related to the functional and operational characteristics of the hinges were found in the literature.
In this study was established information about deformation resistance of concealed hinges under adverse load conditions. Loads of 20 kg and 30 kg were applied vertically to the hinged door on vertical axis. The deflection and the functional parameters were measured.
After the tests it was found out the following:
- Different models of hinges have different deflection resistance;
- In some hinges the deformations are out of the acceptable values according to the standard.
