Abstract: A braking system for holding a screen, wherein either on the holder or the screen an elongate base is provided, the elongated base in contact with a first wheel mounted on the second one of the holder or the screen, so that when the base is moved relative to the first wheel, the first wheel is rotated, and a brake module including a second wheel and a third wheel, the first wheel always being in contact with either the second wheel or the third wheel, wherein the second wheel contacts with an adjustable friction brake, and the brake module being rotatable relative to either the screen or the holder, wherein the second wheel can be adjusted to be in contact with the first wheel, to a position not in contact with the first wheel, but instead the third wheel being in contact with the first wheel or vice versa.

Abstract: A height adjustable holder for a multiplate suitable to carry various types of electronic terminals is provided including: d. a base plate having a plurality of apertures in an array through the base plate or a plurality of upstanding ridges; e. a multiplate, slidingly arranged covering the overside of the base plate, where sliding surfaces are arranged between the base plate and the multiplate; f. a manipulation handle arranged between the base plate and the multiplate, which manipulation handle in a first end extends beyond the multiplate, and in an opposite end is provided with a hook portion, where the distal end of the hook, faces the base plate, and where a pivot is between the multiplate and the manipulation handle whereby the hook may be brought into engagement with an aperture or a ridge, thereby arresting the multiplate's sliding ability in one direction relative to the base plate.
