Definitions
- the invention relates to a pianoforte instrument, in particular a piano, with a pedestal and with several supports for placing on a floor.
- Pianoforte instruments in particular pianos, in addition to the primary sound elements such as the keyboard, the strings and the soundboard soundboard also have a housing with subframe and top frame, in which these elements are arranged or to which they are attached.
- such a housing with sub-frame and upper frame, in which the soundboard and the strings are arranged rests on a pedestal with a skirting board.
- Attached to the upper frame is the keyboard with a chair bottom, a lock strip and a key flap.
- the keyboard must be operable by the operator. It therefore protrudes forward from the body or subframe. Underneath the keyboard in front of the subframe is a free space in which the pianist's knees and lower legs are located while the piano is playing, while the pianist's hands also move on and above the keys of the keyboard during piano playing.
- the keyboard is additionally supported on the side by the pianist.
- consoles are provided, which are supported on a foot block.
- the foot pads are connected to the skirting board.
- the object of the invention in contrast, is to propose a generic pianoforte instrument which creates a possibility of achieving an improved vocal integrity in spite of unevenness in the floor, without complex and complicated constructions, for example with complete floor panels and an artificial three-ply mounting, such as to proceed in the US-PS 2,486,354.
- This option achieves a significant improvement in the vocal range of a piano instrument. It is a four-point bearing in which two out of four support points are height adjustable. As a result, it is also possible here to compensate for unevenness in the substrate, specifically by actively adjusting and / or adjusting the support points. However, the invention goes beyond the simple compensation of unevenness and thus the avoidance of a kippelnden instrument clearly.
- the height adjustment according to the invention made possible by two supports makes it possible to reliably set a uniform load of all four supports.
- the egg lstel lability of two supports also allows manual adjustment, which is vorappelbar without much effort. The user can feel very clearly whether the support he has just set is now without load or with load or if it possibly has no contact with the ground, which would automatically cause a tipping.
- the two front, a Tatstatur facing supports are each equipped with a height adjustment device.
- this adjustability is provided at one or both support points forming the front points seen by the player.
- This has the advantage that also the readjustment can be done where the player has access, which is particularly important if he wants to move the piano, for example, to a lecture just to another point of a room and of course interested in it is that just after this move a then possibly changed ground position can also be compensated directly by himself.
- a transport facilitating device is provided on each of the supports, and that the transport facilitating device each having a sliding member which allows sliding on the floor.
- a piano instrument is not only more vocalized than conventional piano instruments, but is also endowed with a better opportunity for occasional transportation within living spaces or venues.
- the brass rollers used exclusively in the prior art are completely eliminated in this preferred embodiment. This is very unusual for a person skilled in the art, since, on the basis of his experience, wheels and wheels are considered the means of choice for moving comparatively heavy objects. A renunciation of this proven and popular remedy seems anachronistic. This is even more so as the person skilled in the art knows that the wooden or plastic foot blocks conventionally used without the rollers have been quite unsuitable for moving or transporting the piano. If one had tried to "slide" a piano on such a foot block, damage to the floor covering would have been very likely.
- This surface does not change by rolling the brass rollers on the floor and thus the forces are introduced into the floor via constantly other parts of the lateral surface of the respective brass rollers.
- the area available in this embodiment is clearly larger. There is always the area of four elements also available, namely four sliding elements, one on each support.
- the baseplate also has approximately the same longitudinal dimension, but a significantly wider and, for example, each one or two centimeters wider than the measuring angle.
- the two rear support points seen from the player are also equipped with sliding elements, but these are not necessarily equipped adjustable.
- a suitably equipped support pile would be sufficient for adjustability; a use of particular identical adjustable sliding elements but in addition to the above already explained additionally has the advantage of allowing the player to access directly from him as not just estimated page, without having to try hard. In addition, this gives a visual balance between left and right.
- the sliding elements are provided with a possibility of attack for a hexagonal key. This is easy for non-technicians to understand, and yet also suitable, despite the relatively high weight loads of a piano, without any difficulty, to provide an adjustment capability for extending and retracting.
- This adjustment option ensures that the weight can be distributed evenly over all four support points and that the piano's sound body remains dimensionally stable.
- the contact surface is covered with a lubricious and abrasion-resistant plastic.
- the material has proven particularly useful. Among other things, it is offered under the trade name "Delrin.”
- the displacement and mobility of the piano is particularly well supported, without causing scratches in the floor of a parquet floor, on the other hand, the forces are reduced, which move the Pianos are required, and finally it is also avoided that there are signs of abrasion on the floor or the sliding elements wear too quickly.
- the increased footprint through the sliders causes significantly less punctual pressure to be applied to the floor than is conventionally the case with the use of rollers.
- the permanent static pressure load on the floor by a piano will cause by the use of the sliding elements according to the invention significantly less damage, for example by the impressions of the uppermost parts of the floor.
- the height adjustment of the support points which is so sensible for the vocal posture of the pianoforte instruments, can also be made significantly more user-friendly by the use of sliding elements instead of the conventionally used rollers. This is supported by the geometry of the sliding elements.
- a sliding element can, as long as it is depressurized, manually adjusted by turning in height.
- a roller conventionally provided at this point has two free rotation axes, namely a rotation axis concentric to the roller rolling surface and a further rotation axis orthogonal to the former.
- a roller with a threaded shaft analogous to that of a sliding element can not be adjusted in height by a rotation by hand.
- Such a non-pressurized roller would merely rotate about its free axis in an attempt, but without changing the relative height to the pedestal or piano body.
- tools would always be required in this case. In this respect, therefore, an advantage arises in a combination sliding element with a height adjustment.
- Figure 1 is a schematic overall view of an inventive
- Figure 2 is a perspective view of a detail of Figure 1;
- FIG. 3 shows a schematic section through the detail of Figure 2.
- a piano 10 with a keyboard 1 1 and a body with upper frame, subframe and base 12, in which there are, among other things, the soundboard and the strings, which are not visible in the illustration.
- the piano 10 rests on an uneven floor 20 and stands on it with four feet or supports 21.
- the feet 20 of the two supports 21 are instead equipped with other shapes of support elements 30.
- Each of these support elements 30 is equipped with a sliding element 31.
- Two These support elements 30 are additionally equipped with a height adjustment device 32.
- FIG. 2 A corresponding section in FIG. 2 can be seen, in which the area of a foot 21 with a support element 30 can be seen enlarged.
- the support element 30 has a sliding element 31 as well as, for example, a height adjustment device 32, with the aid of which the sliding element 31 can be moved upwards and downwards.
- the sliding member 31 is covered with a layer which is particularly low friction and abrasion resistant.
- polyoxymethylene is preferred as the material.
- the height adjustment device 32 has a threaded bolt 33 which can be used by means of an adjusting nut 34 for height adjustment of the support element 30 relative to the base 12.
- FIG. 3 shows the support element 30 with the sliding element 31 and the height adjustment device 32 in section.
- the figures do not show that the keyboard 1 1 is additionally supported by brackets (not shown).
- the consoles protrude to the left and right of the user from the keyboard to the bottom.
- These consoles can be provided on their underside with supports, in which case the drawn in Figure 1 feet 21 are replaced by these supports 21 under the consoles.
- the brackets can be connected to the base 12 by a skirting board or a supplementklotz. LIST OF REFERENCE NUMBERS
