Definitions

• the invention relates to a keyboard arrangement according to the features of the preamble of claim 1.
• Keyboards as data input devices for personal computers or the like usually have the form known from typewriter technology, according to which several rows of keys arranged one above the other are accommodated in a parallel arrangement in a common, largely rectangular keyboard housing.
• typewriter technology according to which several rows of keys arranged one above the other are accommodated in a parallel arrangement in a common, largely rectangular keyboard housing.
• Such a keyboard suits the operators practicing in blind typing technology, it is also very space-saving, but forces the user to write with closely fitting arms and parallel alignment of the two hands. This cramped posture often leads to physical exertion, including neck and neck strain, especially during prolonged writing phases
• the present invention is therefore based on the object of creating an ergonomic point of view both with regard to the opening angle and with respect to the lateral, i.e. roof-shaped inclination of variably adjustable keyboard so that the structural intervention in the keyboard and the additional effort for the adjustment can be kept as low as possible.
• FIG. 1 shows a keyboard arrangement according to the invention in the basic position
• FIG. 2 shows the keyboard arrangement according to FIG. -1 in a tilted position
• FIG. 3 shows the keyboard arrangement according to the invention with spread-out key fields
• FIG. 4 shows a section of the keyboard arrangement according to FIGS. 1 and 2 in the area of the floating bearing
• FIG. 5 shows a schematic top view of the floating bearing according to FIG. 4.
• FIG. 1 shows a keyboard arrangement designed according to ergonomic aspects in the basic position.
• This keyboard arrangement consists of two keyboard part housings 1, 2, a support plate 3 attached to the base plates of the two part housings 1, 2, common to both part housings, and a base 4 arranged underneath.
• FIG. 2 shows the arrangement according to FIG. 1 with a roof-shaped or lateral inclination, the support disk 3, which can be tilted on both sides about a hinge-like joint 5, being fixed in this tilting position by a retaining web 6 which can be folded out of the base 4.
• a smaller angle of inclination can be set by a further retaining web 7, which can also be folded out of the base 4.
• Both retaining webs 6, 7 are supported on the support disk 3 along the hinge-like joint 5.
• the retaining webs can also be provided in the supporting disk 3, in which case they can be supported, for example, in a groove in the base 4.
• the support disc 3 is on one side via a fixed bearing 8 designed as a hinge on the other side by means of a
• FIG. 3 shows the keyboard arrangement with the base removed. It shows the support disk 3 with the hinge-like joint 5 running in the region of the dividing line between the two keyboard housings 1, 2, which preferably is used as a film hinge, ie as a thin plastic strip in the plane if plastic support disc 3 is integrated.
• the support disk 3 has a plurality of cutouts 10 designed as circular arc sections, into which latching hooks 11 formed on the underside of the keyboard part housing 1, 2 engage. Further latching hooks 12 grip the support disk 3 on its outer edges.
• the centering of the two sub-housings 1, 2 with respect to the circular-arc-shaped recesses 10 in the support disk 3 takes place by means of circular segments 13 provided in the region of the pivot point, which are adjustable in the radial direction.
• FIGS. 4 and 5 show a floating bearing for the support disk 3 provided on the base 4.
• This floating bearing consists, on the one hand, of a pair of rails 14 arranged on the base 4 and sloping inwards, on which the support disk 3 is slidably supported and, on the other hand, of a pair ⁇ immersing gripping arm 15 sliding behind both rails.
