Description

[Technical Field]

[0001] The present invention relates to an auxiliary music stand and an auxiliary music stand set, and more particularly to an auxiliary music stand and an auxiliary music stand set that can be suitably used for a grand piano. [Background technology]

[0002] Auxiliary music stands for grand pianos have been known for some time, featuring a rectangular backboard with a width corresponding to the size of normal sheet music, with a music rest a few centimeters wide formed on one of the two longer sides of the backboard at an angle slightly larger than a right angle, forming an inverted L-shape; the side of the backboard with the music rest is the front side, and on the back side of the backboard, a support plate is formed that fits snugly against the backboard from directly behind the lowest music rest to approximately the center height, and then bends at an angle of about 110° from that point in the opposite direction to the music rest and extends straight (see, for example, Patent Document 1).

[0003] This auxiliary music stand for grand pianos has a support plate that extends from the back at an angle of approximately 110° and is inserted into the gap between the underside of the grand piano's music stand and the top of the lid. This allows the auxiliary music stand to be installed lower than the grand piano's music stand, making it easier for short children to see the sheet music when playing the grand piano. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-018198 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the configuration of Patent Document 1, the auxiliary music stand is installed by inserting a support plate that extends long backward into the small gap between the underside of the grand piano's music stand and the top surface of the lid.However, since the support plate must be inserted carefully and deeply so as not to damage the high-quality grand piano, there is a problem in that installing an auxiliary music stand for a grand piano requires a great deal of effort and time.

[0006] Furthermore, if there is a large gap between the underside of the grand piano's music stand and the top of the main roof, the auxiliary music stand is likely to become unstable. Therefore, in order to prevent the auxiliary music stand from slipping off, it is necessary to ensure that the support plate has sufficient extension length. This results in a large overall size, which poses the problem of requiring a large space for storage when removed.

[0007] Furthermore, when the auxiliary music stand is removed from the grand piano, the back panel is not freestanding, but stands up in a triangle with the bottom edge of the back panel and the tip of the support panel, which creates the problem that it requires a large space for storage and must be stored in an unstable state.

[0008] Therefore, the present invention provides an auxiliary music stand and auxiliary music stand set that can be easily fixed to a grand piano in a short time and has a compact shape that is easy to store. [Means for solving the problem]

[0009] In order to achieve the above object, the auxiliary music stand of the present invention comprises a music stand support plate capable of supporting the back of a music sheet on its surface; a lower end support portion provided at a lower end of the music stand support plate so as to protrude from the surface and capable of supporting a lower end of the music stand; The music stand support plate has a clamping portion provided on the rear surface of the music stand support plate and capable of supporting the music stand support plate by clamping it.

[0010] The auxiliary music stand set according to the present invention comprises the auxiliary music stand, The grand piano further includes a U-shaped fixing member that is attached to and fixes the frame of the grand piano so as to sandwich the end of the keyboard pig from above, so that the keyboard pig does not close when the keyboard pig of the grand piano is fully opened. [Effects of the Invention]

[0011] According to the present invention, the music score can be supported at a low enough position that even small children can easily see it. [Brief explanation of the drawings]

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0014] The structure of an auxiliary music stand according to an embodiment of the present invention will be described with reference to FIGS.

[0015] FIG. 1 is a front view of an auxiliary music stand according to an embodiment of the present invention.

[0016] As shown in FIG. 1, the auxiliary music stand 50 according to this embodiment has a music stand receiving plate 10 and a support plate 20.

[0017] Music stand support plate 10 is a horizontally long rectangular plate-like member, and its surface, music stand support surface 11, supports the back of a musical score (not shown). Therefore, the width of music stand support plate 10 is longer than the length of the musical score when it is unfolded. The height is also set to be higher than the height of the musical score.

[0018] The music stand support 10 can be made of various materials, but resins such as plastic or metal are preferable, and resins such as polypropylene are particularly preferable. For example, plastic cardboard made of polypropylene resin may also be used.

[0019] The two upper corners of the music stand support may be rounded, for example. In Figure 1, the two upper corners of the music stand support 10 are rounded to form curved corners rather than right angles.

[0020] Additionally, side covers 15 are provided on the top edge and the left and right edges of music stand support 10 to cover the edges of music stand support 10. These are provided to protect the sides of music stand support 10 and to prevent damage to the grand piano. However, side covers 15 are not essential and may be provided as needed.

[0021] Side covers 15 can be made of various materials as long as they have a protective function, but they may also be made of elastic materials such as synthetic rubber or rubber. For example, the periphery of music stand support 10 may be made of metal such as steel, and this area may be covered with side covers 15 made of synthetic rubber.

[0022] The support plate 20 is easier to understand in FIG. 3 than in FIG. 1, so will be described using FIG.

[0023] 3 is a side view of the auxiliary music stand 50 according to the embodiment of the present invention. In FIG. 3, the left side is the front side (front) and the right side is the back side (rear).

[0024] 3, support plate 20 is a plate-shaped member that supports music stand support plate 10 from below. The front surface (front side) of support plate 20 protrudes forward to form forward protrusion 21, and the back surface of support plate 20 protrudes backward to form rear protrusion 22.

[0025] The upper surface of the forward protruding portion 21 forms a music sheet support portion 21a that supports the lower end of a music sheet when the music sheet is placed on it.

[0026] As shown in FIG. 1, from the front, a support plate 20 and a forward protrusion 21 are provided at the lower end of the auxiliary music stand 50, and the upper surface of the forward protrusion 21 forms a music sheet support portion 21a that supports the lower end of the music sheet.

[0027] 2 is a rear view of the auxiliary music stand 50 according to this embodiment. The rear surface of the auxiliary music stand 50 has the rear surface 12 of the music stand receiving plate 10, the rear protruding portion 22 of the support plate 20, and the clamping portion 30.

[0028] The rear surface of the music stand receiving plate 10 is not the surface for receiving the music, so it does not need to be flat, and a clamping portion 30 is provided.

[0029] The support plate 20 also extends horizontally rearward to form a rearward protruding portion 22, which together with the forward protruding portion 21 forms a rectangular plate-like member and supports the music stand receiving plate 10 so that it can stand on its own.

[0030] Clamping unit 30 is an attachment mechanism for fixing auxiliary music stand 50 to a plate-like structure. Clamping unit 30 has an upper clamping member 31 on the upper side and a lower clamping member 32 on the lower side. When there is a plate-like structure such as a plate-like member that extends laterally, i.e., approximately horizontally, upper clamping unit 31 and lower clamping unit 32 can clamp the plate-like structure from above and below to attach it to the plate-like structure.

[0031] For example, when the fallboard of a grand piano is fully opened and lifted up, the tip of the fallboard, i.e., the part that is located at the bottom when the fallboard is closed, protrudes almost horizontally. The clamping part 30 can be attached so that it sandwiches this most protruding, almost horizontally extending part from above and below, and the auxiliary music stand 50 can be fixed in place.

[0032] Therefore, it is preferable that the distance between the upper clamping member 31 and the lower clamping member 32 is set to be slightly wider than the thickness of the plate-like structure.

[0033] The clamping unit 30 is preferably made of a material with a certain degree of elasticity, such as metal, resin, rubber, or synthetic rubber. This is because a material with a moderate degree of elasticity can ensure a sufficient clamping force between the upper clamping member 31 and the lower clamping member 32. For example, the clamping unit 30 may be made of a metal such as steel, and its periphery may be covered with an elastic material such as synthetic rubber. This ensures both strength and elasticity.

[0034] Referring again to FIG. 3, the structure of the auxiliary music stand 50 according to this embodiment will be described in more detail.

[0035] 3, support plate 20 extends horizontally from front to back, and music stand support plate 10 extends vertically above support plate 20. That is, support plate 20 serves to support music stand support plate 10.

[0036] If the support plate 20 extends too far forward (toward the front), it will get in the way when viewing the music sheet, so it extends only short enough to stably hold the music sheet. On the other hand, the back side of the support plate 20 does not get in the way even if it extends too far backward, so it extends far enough to ensure a length and area sufficient to support the music sheet support plate 10.

[0037] In this way, the auxiliary music stand 50 of this embodiment stands on its own in a vertically elongated shape, and since the rearward extension width of the rearward protrusion 22 and the rearward extension width of the clamping portion 30 are not large, the overall shape is thin and it can be stored in a space-saving manner when not in use.

[0038] The front side of music stand support plate 10 on the left side forms music stand support surface 11, which functions as a surface for receiving the back of a music stand (not shown). Additionally, an upper surface 21a of forward protrusion 21 protruding forward from support plate 20 forms a music stand support portion that supports the lower end of the music stand (not shown).

[0039] A clamping section 30 is provided at the bottom of the rear surface of the music stand support plate 10. As explained in Fig. 2, the clamping section 30 has an upper clamping member 31 and a lower clamping member 32. Both the upper clamping member 31 and the lower clamping member 32 extend rearward, and are configured to be able to clamp a plate-shaped member from above and below.

[0040] Of the clamping section 30, the upper clamping member 31 has a shape that extends far rearward because it receives a greater load in order to support the weight of the auxiliary music stand 50. On the other hand, the lower clamping member 32 is not subjected to the weight of the auxiliary music stand 50 and only needs to clamp the edge of the fall board to fix its position, so it is configured to be shorter than the upper clamping member 31.

[0041] The tip 31a of the upper clamping member 31 has a shape that opens slightly upward, and the tip 32a of the lower clamping member 32 has a shape that opens slightly downward. This is to make it easier to attach the clamping unit 30 to the piano's fallboard, as the fallboard easily fits into the groove in the clamping unit 30, allowing for smooth, fixed installation of the auxiliary music stand 50. This makes it easy to install the auxiliary music stand 50 on the grand piano in a short amount of time.

[0042] The distance between the lower surface of the upper clamping member 31 and the lower clamping member 32 is set to be slightly wider than the thickness of the grand piano fallboard, in order to be able to hold the grand piano fallboard securely and not to tighten the grand piano fallboard with more stress than necessary.

[0043] It is preferable to provide multiple clamping units 30 spaced apart on the left and right as shown in Fig. 2. For example, if one clamping unit is provided on each side as a pair, auxiliary music stand 50 can be securely fixed.

[0044] However, the number of clamping parts 30 is not limited to two, and may be three or more, or may be a structure with only one long clamping part 30. The number of clamping parts 30 can be set to any number depending on the application, as long as it allows the auxiliary music stand 50 to be fixed to the keyboard cover of the grand piano.

[0045] 1 and 3 of this embodiment, the clamping portion 30 is located below the center of the height of the back surface 11 of the music stand support plate 10, but if you want to lower the height of the music stand, the clamping portion 30 may be located at about the middle or above the middle. In this way, the mounting height of the clamping portion 30 can be set to any height depending on the application.

[0046] Next, a method for attaching the auxiliary music stand 50 according to this embodiment to a grand piano will be described with reference to FIGS.

[0047] FIG. 4 is a diagram showing an example of a grand piano 100 to which the auxiliary music stand 50 according to this embodiment is to be attached.

[0048] The keyboard of the grand piano 100 is covered by a fallboard 110. The fallboard 110 has a top cover part 111 that extends laterally to cover the top of the keyboard, and a side cover part 112 that extends downward to cover the side of the keyboard, and its cross section is configured to be roughly L-shaped with rounded corners.

[0049] A portion called a front frame 130 is provided behind the fall board 110. Further behind the front frame 130 is a portion where strings are stretched (not shown).

[0050] 5 is a diagram showing the state in which the fallboard 110 of the grand piano 100 is fully open. By lifting the fallboard 110 upward and opening it, the keyboard 120 is exposed. In this state, the grand piano 100 is played.

[0051] When the fallboard 110 is lifted up and opened, the top cover 111 of the fallboard 110 stands up vertically, and the side cover 112 extends horizontally in a generally horizontal manner. The tip of the side cover 112, i.e., the end that is located furthest down when the fallboard 110 is closed, protrudes forward, with the tip 112a located closest to the player. The tip 112a of the fallboard 110 and the front frame 130 are also positioned close to each other.

[0052] FIG. 6 shows the auxiliary music stand 5050 being aligned before being attached to the grand piano 100.

[0053] As shown in Figure 6, auxiliary music stand 50 is placed in a position where clamping section 30 can be fitted into tip 112a of side cover section 112 of keyboard lid 110. The height of auxiliary music stand 50 is set so that tip 112a is sandwiched between upper clamping member 31 and lower clamping member 32 of clamping section 30. The lateral position of auxiliary music stand 50 may be set at a position that makes it easy for the performer to see the music, but it is generally set in a central position.

[0054] 7 is a diagram showing the auxiliary music stand 50 installed on the grand piano 100. The clamping portion 30 of the auxiliary music stand 50 clamps the side cover portion 112 of the fall board 110 from the tip 112a, and the auxiliary music stand 50 is moved until the tip 112a reaches the back of the groove of the clamping portion 30, and the auxiliary music stand 50 is fixed to the fall board 110.

[0055] In addition, since the auxiliary music stand 50 according to this embodiment has clamping sections 30 on both the left and right sides, the auxiliary music stand 50 is attached to the keyboard cover 110 by pushing it in so that the tips 112a of the side cover sections 112 of the keyboard cover 110 reach the depths of the clamping sections 30 on both the left and right sides.

[0056] The music stand that is originally installed on a normal grand piano extends upward from the height of the front frame 130, making it too high for children such as toddlers and elementary school students and making it difficult to see. However, by installing the auxiliary music stand 50 according to this embodiment, the height at which the music is held can be lowered and the music can be placed closer to the keyboard 120, making it easier for even children with a shorter sitting height to see the music.

[0057] Furthermore, because auxiliary music stand 50 can be installed simply by attaching it to tip 112a of open fall board 110, the installation can be easily done by hand, and auxiliary music stand 50 can be installed in a short time with little effort. Specifically, installation is completed in an instant, taking about one second.

[0058] FIG. 8 is a diagram illustrating the state in which the fixing member 40 of the auxiliary music stand set is attached. In FIG. 8, in addition to the auxiliary music stand 50, an auxiliary fixing member 40 is also installed on the grand piano 100. The fixing member 40 is a restricting member that prevents the fallboard 110 from closing and secures the fallboard 110 in a fully open position. The fixing member 40 has a U-shape and is inserted from above between the inside of the front frame 130 (the side opposite the keyboard 120, i.e., the string side) and the tip 112a of the side cover portion 112 of the fallboard 110, clamping it from the outside to restrict movement of the fallboard 110. This ensures that the fallboard 110 remains fully open. Since the auxiliary music stand 50 is often used by children, the fixing member 40 prevents the fallboard 110 from closing, allowing the grand piano 100 to be played safely.

[0059] Figure 9 is a diagram showing an example of a method for installing fixing member 40. As shown in Figure 9, fixing member 40 is U-shaped, and can be installed from above so as to sandwich front frame 130 and tip 112a of fall board 110 from the outside, thereby fixing fall board 110.

[0060] In Figures 8 and 9, the fixing member 40 is configured in a shape that fits perfectly to the distance between the front frame 130 and the tip 112a of the fall board 110, but it may also be configured to have a size that allows for a little more room in the horizontal part and that bulges upward to form an arch shape.

[0061] The fixing member 40 is preferably made of a material with a certain degree of elasticity, such as metal, resin, or synthetic rubber. This makes it possible to fix the fall board 110 without applying excessive stress to the grand piano 100. For example, the fixing member 40 may be made of a metal material, such as steel, covered with an elastic material, such as synthetic rubber.

[0062] Furthermore, the fixing member 40 may have different lengths for the portion extending in the vertical direction that hangs over the front sill 130 and the tip 112a of the fall cover 110. For example, the length of the portion extending in the vertical direction that hangs over the tip 112a of the fall cover 110 may be configured to be longer than the portion extending in the vertical direction that hangs over the front sill 130. This is because the side of the fixing member 40 facing the front sill 130 mainly serves to fix the position, while the side of the tip 112a of the fall cover 110 mainly functions as a stopper to prevent the fall cover 110 from falling, and so the length may be configured to be longer in consideration of the thickness of the side cover portion 112 of the fall cover 110.

[0063] 8 and 9 illustrate an example in which two fixing members 40 are used, but again, one or more than two fixing members 40 may be used depending on the application. However, using two fixing members 40 in a pair on the left and right provides high safety and does not require much effort for installation, making it preferable in terms of balance.

[0064] Furthermore, the fixing member 40 may be attached after the auxiliary music stand 50 is installed on the grand piano 100, as shown in FIG. 8, or may be attached before the auxiliary music stand 50 is installed on the grand piano 100, as shown in FIG. 9.

[0065] In this way, the auxiliary music stand set is made up of the auxiliary music stand 50 and the fixing member 40. The auxiliary music stand 50 alone can achieve the purpose of bringing the music closer to the eye for easier viewing, but by adding the fixing member 40 to form an auxiliary music stand set, the fallboard 110 can be fixed in the fully open position, ensuring safety.

[0066] Furthermore, the auxiliary music stand 50 and auxiliary music stand set can be mass-produced for the standard size of the grand piano 100, or can be individually manufactured to fit the size of each individual grand piano 100. By specifying the size and arrangement of the auxiliary music stand 50 and auxiliary music stand set individually to match the size of each individual grand piano 100 and the physique of the player, a configuration that is more suited to each individual application can be achieved.

[0067] Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. [Industrial Applicability]

[0068] The present invention can be used for auxiliary music stands, and is particularly suitable for use as auxiliary music stands for grand pianos. [Explanation of symbols]
