Definitions

• the present invention concerns a cover for the lid of a grand piano.
• a grand piano cover which consists of a cloth material, e.g. woollen flannel or padded material to improve the protection of a grand piano lid.
• a said known grand piano cover is held in place by means of a number of elastic straps (86) , which does not look so good from the direction where the audience sits and looks at the pianist and the orchestra.
• a said selected cloth material is thereby not selected to particularly prevent reflection from spotlights and other lamps but is only intended for protection purposes, i.e., to be soft and protect the grand piano lid against impacts.
• the cover of US 6172293 Bl is thereby inappropriate to use during a concert.
• the main object is primarily to solve said problems by simple means and remove annoying reflections from grand piano lids and also protect from abrasion and wear of grand pianos when these are standing open as well as make clear important visual impressions at certain situations for surrounding persons.
• Fig. 1 shows the cover according to the present invention in extended state on a grand piano lid
• Fig. 2 shows a stage of the application of the cover on a grand piano lid
• Fig. 3 shows a further stage of the application of the cover on a said grand piano lid, edge to edge with the transverse hinges of the grand piano lid,
• Fig. 4 shows the raising stage of the front pivotably journalled lid portion of the grand piano lid
• Fig. 5 shows said lid portion in fully turned-up and lowered position prepared for playing while the flap-shaped piece of the covering is in position prepared for folding above the lid portion
• Fig. 6 shows the flap- shaped piece in extended state above the lid portion ready for raised play position
• Fig. 7 shows the grand piano lid in raised and raised play position having a cover applied thereon
• Fig. 8 shows a grand piano with the lid thereof having cover in lowered closed state.
• Figs. 1 and 7 the cover 1 is shown when it is placed and prepared, fast and smoothly, on the grand piano 2.
• the grand piano lid 4 is thereby ready to be raised by support 3 if desired.
• the cover 1 protects the surroundings (the orchestra) from undesired reflections in the lid 4 as well as makes the conductor clear for the orchestra members.
• the cover 1 protects the grand piano 2 from wear and abrasion.
• Fig. 2 shows in the first instant how it is recommended to place the cover 1 on the grand piano 2. Before the cover has been rolled up, folded up or hanging on a hanger and then it has been placed on the slender part of the grand piano lid and then unrolled, after that the smaller transverse part 12 of the cover 1 is unfolded as shown by the arrow 6 in the picture.
• Fig. 3 shows how it is recommended to place the cover 1 edge to edge with the transverse brass hinges 7 of the grand piano lid. This is done so that the cover 1 should position itself correctly automatically at the other end and not protrude a bit over that edge.
• Fig. 4 shows when the front part 8 of the grand piano lid 4 is folded over.
• the part 8 that has a cross beam 9, and lets the weight of said part 8 then press the cover 1 against the large part 10 of the grand piano lid 4 while the remaining part of the cover rests by itself against the grand piano lid 4, so as to in such a way fix and hold in place the cover 1, also when the lid 4 is raised by its stay 3.
• This way to hold in place the cover 1 makes then it very difficult for it to slide off the lid 4 when it is raised.
• the materials of this part 11 of the cover have extra firmness and steadiness. This is provided by the different materials included in the cover 1 being laminated together, e.g. by agglutination or in another known way.
• Fig. 5 shows how finally the entire transverse part 16 of the cover 1 is put on top of the front raised part 8 of the grand piano lid, as the arrow 13 shows, so that the cover 1 also covers this part 8 of the lid 4 of the grand piano with its cross beam 9
• Fig. 6 shows the shown blacked out part of the cover 1 and has in addition on its under side a special material that attaches extra good to the very glossy grand piano lid 4.
• Fig. 7 shows a phase of grand piano 2 having open lid
• Fig. 8 shows a grand piano 2 having closed lid 4.
• Fig. 9 shows an example of a cover having a channel intended for the hanging of the cover using a hanger .
• Fig. 10 shows an example of a hanger which may be used together with the cover.
• the cover 1 is formed of a flexible piece which essentially is adapted in shape to the circumference of a grand piano lid and which on the under side 1A of said cover 1 has slide-preventing protuberances 14 situated at mutual distances A, B from each other, and that the upper side IB of said cover is formed of a textile 15 having cut or angled pile
• the pile consisting of natural and/or synthetic material having good light reflection-reducing ability, at least when it is rotated at a certain angle.
• the pile is angled and is not standing primarily perpendicularly from the material, the angle is obtained by rotating the fabric to the position where the reflections become minimal and is determined by how the pile is lying in relation to the source of light for the respective grand piano.
• the pile is essentially directed away from the source of light to achieve the least reflections.
• a said cover is easily compactable, when it is not intended to be used, by being rolled up or folded together, i.e., possible to roll up or foldable.
• the cover has a thickness of between 1 and 10 mm,
• the cover is approx. 155 cm x 260 cm as the longest in the width and longitudinal direction and has the shape of the lid 4 of the grand piano. Folded up, the cover can be got to a size of approx. 40 cm x 60 cm x 10 cm. Alternatively, the cover is hung up on a hanger intended for this. It may also be formed of a number of interconnectable pieces, which together partly or
• the cover 1 is formed of an entire piece which reaches from the end of the slender part of a grand piano all the way up to the hinge 7 of a pivotable lid portion 8 as well as a sewed up, etc., or detachably fixed flap-shaped piece 16 fixed at the area to where the lid portion 8 reaches in raised position over the fixed part of the lid of the grand piano, i.e., similar to Y-shaped.
• the protuberances 14 are distributed along the surface of, e.g., a cloth, a textile material, or a plastic material and are in the form of uniform or nonuniform plastic and/or rubber studs, and form under side 1A of said cover 1 with slide-preventing function, while the upper side of the cover 1 is formed of a velvet-like textile having cut or angled pile turned into correct position and of dark colour.
• the distance between the protuberances may be between some mm to a few cm, for instance 1 mm, 5 mm, 1 cm, or 2 cm. According to a
• a flap- shaped piece 16 of the cover 1 is detachably connectable with the remaining piece 17 of the cover 1 by means of zip fastener, Velcro ® fastening elements, or another fastening means 18, for covering the entire grand piano lid in the lowered position thereof.
• Said flap-shaped covering piece 16 is arranged foldable across the main part of the lid 4 over the foldable end portion 19 of the grand piano lid 4, and is provided with a recess 20 or depression so that a cross beam having a lock housing 9 on the lid 4 could be surrounded.
• Said flap-shaped covering piece 16 is preferably provided with desired text, etc., 22 thereon, on one side thereof or both sides, which said text 22 is arranged on a foldable tab 23 or strip of said flap-shaped covering piece 16.
• Said flap-shaped covering piece 16 is arranged to be situated next to the pivotable lid portion 8 of a grand piano lid and is arranged to be retained together with the other part 11 of the cover 1 on a leaning raised grand piano lid 4.
• Fig. 2 shows the application of a cover on a grand piano lid 4 in the direction 24 from the more slender lid portion of the grand piano toward the lid portion 8 of the grand piano.
• the circumference edge of the cover which preferably has sound- absorbing material in the same, is provided with a suspendable edge portion extending along the side circumference edge of a covering grand piano lid and along the cover, pockets, not shown, are arranged to be fastened by means of Velcro® fastening means for the receipt of objects therein.
• attaching, lowermost material is manufactured from a material containing polyolefin elastomers, polyester, or silicone. Furthermore, this material is safe against a possible destructive chemical reaction between the material and the varnish of the grand piano. This may be of great importance since a concert grand piano may cost up to SEK 1 700 000 and is very expensive to restore after damage.
• the cover of US 6172293 Bl has no one of these properties. In order for their cover to be possible to remain in place when the lid is raised at approx. 30° angle, it should be required that this cover fits tight around the lid as well as runs over the edge and makes this along the very long edge of the entire lid. For safety's sake, their cover has also a strap which is running on the underside of the lid to better be able to hold it in place.
• the present cover does not have to fit tight, slip over the edge, or have any strap but follows precisely the contours of the grand piano lid in order not to be seen at all for the audience in front of the grand piano in the auditorium, still it remains very reliably on the lid.
• US 6172293 Bl it also seems hard to get this large piece of fabric to keep the springiness around the entire long edge so that it does not loses attachment at some place making it to retract and slide off.
• the cover does not fully cover all reflecting surfaces on the grand piano lid which it has to make for the purpose.
• Said known cover does not entirely cover a part of the part of the grand piano lid that is folded over, such as the cross beam having a lock housing on the same part that is folded over.
• the cover according to the present invention covers these parts, which is very important in order not to give rise to any disturbing reflections.
• the tab it is a piece of fabric (part of the cover) which affords the experience of the grand piano lid as a large and smooth surface.
• the text printed or embroidered on this tab 23 or strip may be features of a commercial kind (a company name) or more informative such as a philharmonic society/orchestral association. If it is temporary desired to conceal this text (or produce another text) , the tab 23 is turned over to the other side instead, and which may lack text, etc., or which has another text or logo. This is achieved by the tab 23 being attached with its one long side to the upper side of the flap-shaped covering piece 16, which makes that it easily can be folded over according to the above description.
• the cover 1 comprises a channel 25 intended for the hanging of the cover 1 using a hanger.
• the cover may be provided with a channel 25 or tunnel that is attached to the cover 1 with extension from the edge of the respective long side of the cover 1 along the fastening means 18.
• the channel 25 is arranged to receive a hanger which then may be hung up in a suitable place, e.g. in a storage space or on a hook in a wall.
• the channel 25 consists of a piece of fabric that has been fastened in both ends by a seam so that a through passage is formed transversely to the cover 1.
• An example of a hanger 26 that may be used together with the cover has a hook 27, an upper part 28 which transforms to a lower part 29 according to Figure 10.
• the lower part 29 has a length which is longer than the upper part 28 and which preferably is as long as or longer than the length of the channel 25.
• the hanger 26 may have a cord 30 which then is fastened in a ball 31 at the end of the lower part 29 of the hanger 26 to render the hanger 26 extra stability when the cover 1 is
• the hanger 26 may be made of plastic or metal.
• the hanger 26 may also be of another kind than what is shown in Figure 10 as long as a part of the hanger 26 can be inserted into the channel 25.
• the channel 25 may also be present when the cover 1 only consists of a continuous piece.
