A pianoforte instrument with a base (12) forming a soundbox and including a soundboard and strings within the base, a keyboard arranged at a front of the base and the base having four bearings (21) for support on a floor (20), hereby characterized in that two of the bearings (21a) are fixed heigh
1. A pianoforte instrument with a base (12) forming a soundbox and including a soundboard and strings within the base, a keyboard arranged at a front of the base and the base having four bearings (21) for support on a floor (20), hereby characterized in that two of the bearings (21a) are fixed height bearings, the fixed height bearings (21a) being located at a rear of the base,in that two of the bearings (21b) are adjustable height bearings each equipped with a height adjuster (32), the adjustable height bearings (21b) being located at the front of the base facing the keyboard, andin that each height adjuster (32) enables a height adjustment of the respective bearing (21) relative to the base (12) and/or to a console;further characterizedin that a device (30) that facilitates transport is provided on each of the bearings (21); andin that the device (30) that facilitates transport has a slide element (31) in each case, which permits sliding on the floor (20);wherein the two adjustable height bearings (21b) cooperate with the fixed height bearings to permit adjustment of a uniform load onto all four bearings (21), to prevent deformities of the sound box, and to improve tuning stability in spite of floor unevenness; further characterized in that the device (30) includes a recess containing a majority of a main block of the slide element (31); wherein the slide element (31) has a substantially uniform geometry, lacking projections therefrom. 2. The pianoforte instrument according to claim 1, further characterized in that each slide element (31) is provided with a layer of polyoxymethylene. 3. The pianoforte instrument according to claim 1, further characterized in that each height adjuster (32) has a threaded bolt (33) and an adjusting nut (34), wherein rotation of the adjusting nut (34) effects height adjustment of the respective bearing (21) relative to the base (12) and/or to a console. 4. The pianoforte instrument according to claim 2, further characterized in that each height adjuster (32) has a threaded bolt (33) and an adjusting nut (34). 5. A pianoforte instrument comprising: a base forming a soundbox 40 and including a soundboard 42 and strings 44 within the base;a keyboard 11 arranged at a front of the base 12; andfour weight bearing assemblies supporting said base on a floor, wherein two of said weight bearing assemblies are fixed height weight bearing assemblies located at a rear of the base, and wherein two of said weight bearing assemblies are adjustable height weight bearings assemblies each equipped with a height adjuster, the adjustable height weight bearing assemblies being located at the front of the base facing the keyboard, each height adjuster enabling a height adjustment of the respective adjustable height weight bearing assembly relative to the base,each of said weight bearing assemblies including a bearing element that facilitates transport, and a slide element received on the bottom side of said bearing element which permits sliding on the floor;wherein said two adjustable height weight bearing assemblies cooperate with said two fixed height weight bearing assemblies to permit adjustment of a uniform load onto all four bearings, to prevent deformities of the sounds box and to improve tuning stability in spite of floor unevenness; wherein each beating element includes a recess containing a majority of a main block of the slide element; wherein each slide element has a substantially uniform geometry, lacking projections therefrom. 6. The pianoforte instrument according to claim 5, wherein each slide element is provided with a layer of polyoxymethylene on an outer surface of said respective slide element. 7. The pianoforte instrument according to claim 5, wherein each height adjuster has a threaded bolt extending from the respective bearing element, and each height adjuster has an adjusting nut, wherein rotation of the adjusting nut (34) effects height adjustment of the respective bearing (21) relative to the base (12) and/or to a console. 8. The pianoforte instrument according to claim 6, wherein each height adjuster has a threaded bolt extending from the respective bearing element, and each height adjuster has an adjusting nut. 9. A pianoforte instrument comprising: a base forming a sound box 40 and including a soundboard 42 and strings 44 within the base;a keyboard arranged at a front of the base; andfour weight bearing assemblies supporting said base on a floor, wherein two of said weight bearing assemblies are fixed height weight bearing assemblies located at a rear of the base, and wherein two of said weight bearing assemblies are adjustable height weight bearing assemblies each equipped with a height adjuster, the adjustable height weight bearing assemblies being located at the front of the base facing the keyboard, each height adjuster enabling a height adjustment of the respective adjustable height weight bearing assembly relative to the base,each of said weight bearing assemblies including a bearing element that facilitates transport, and a slide element received on the bottom side of said bearing element which permits sliding on the floor;wherein each slide element is provided with a layer of polyoxymethylene on an outer surface of said respective slide element;wherein each height adjuster has a threaded bolt extending from the respective bearing element, and each height adjuster has an adjusting nut; andwherein said two adjustable height weight bearing assemblies cooperate with said two fixed height weight bearing assemblies to permit adjustment of a uniform load onto all four bearings, to prevent deformities of the sounds box, and to improve tuning stability in spite of floor unevenness; wherein each beating element includes a recess containing a majority of a main block of the slide element; wherein each slide element has a substantially uniform geometry, lacking projections therefrom.
