[0002] Works of art, especially paintings and their frames, are exposed to natural fluctuations in humidity and temperature, as well as other environmental conditions. This can cause works of art, such as wooden frames or wooden picture supports, to deform. This deformation can result in permanent cracks and other damage, such as moisture penetration, mold, and the like, which can destroy the artwork.

[0003] Support structures designed to counteract deformation have become known from the state of the art. Metal springs are used to apply a force to the artwork, counteracting the deformation. These springs are firmly connected to the support frame. As a result, the applied force is either too large or too small in the details, depending on the fluctuating environmental conditions.
