Description

Technical Field

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

Background Art

[0002] Conventionally, on a rectangular back plate having a width corresponding to the size of a normal music score, a music score receiver with a width of several centimeters is formed on one of the two long sides so as to form an inverted L shape at an angle slightly larger than a right angle. The side of the back plate where the music score receiver is located is taken as the front side. On the back side of the back plate, a support plate that extends straight after bending at an angle of about 110° in the direction opposite to the music score receiver while closely contacting the back plate from directly behind the lowermost music score receiver to approximately the central height is known as an auxiliary music stand for a grand piano (see, for example, Patent Document 1).

[0003] In such an auxiliary music stand for a grand piano, a support plate that extends at an angle of about 110° from the back is inserted into the gap between the lower surface of the music stand of the grand piano and the upper surface of the grand roof. Thereby, the height of the auxiliary music stand for a grand piano is set lower than that of the music stand of the grand piano, and when a child of short stature plays the grand piano, the music score can be easily viewed.

Patent Document 1

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the configuration of Patent Document 1, an auxiliary music stand is installed by inserting a support plate that extends long backward into a small gap between the lower surface of the music stand of a grand piano and the upper surface of the large roof. However, since it is necessary to carefully insert the support plate deep inside so as not to damage an expensive grand piano, there is a problem that a great deal of labor and time are required for installing the auxiliary music stand for a grand piano.

[0006] In addition, if the gap between the lower surface of the music stand of the grand piano and the upper surface of the large roof is wide, the fixing of the auxiliary music stand tends to be unstable. Therefore, in order to prevent the auxiliary music stand from slipping off, it is necessary to ensure a sufficient length for the extension of the support plate, and as a whole, it becomes large-sized, and there is a problem that a large space is required for storage when it is removed.

[0007] Furthermore, when the auxiliary music stand is removed from the grand piano, the back plate is not self-standing, and since it stands in a structure that forms a triangle at the lower end of the back plate and the tip of the support plate, a large space is required for storage and it has to be stored in an unstable state, which is a problem.

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

Means for Solving the Problems

[0009] To achieve the above object, the auxiliary music stand according to the present invention includes a music stand receiving plate capable of receiving the back surface of the music sheet on the surface, a lower end support portion provided at the lower end of the music stand receiving plate so as to protrude from the surface and capable of supporting the lower end of the music sheet, and a clamping portion provided on the back surface of the music stand receiving plate and capable of supporting the music stand receiving plate by clamping.

[0010] In addition, the auxiliary music stand set according to the present invention includes the auxiliary music stand and, When the key cover of the grand piano is fully opened, it further has a U-shaped fixing member that is attached and fixed so as to sandwich the frame of the grand piano and the end of the key cover from above so that the key cover does not close.

Advantages of the Invention

[0011] According to the present invention, even an infant can support the sheet music at a sufficiently low position where the sheet music is easy to see.

Embodiments for Carrying Out the Invention

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

[0014] Using FIGS. 1 to 3, the structure of the auxiliary music stand according to the embodiment of the present invention will be described.

[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 the present embodiment includes a music sheet receiving plate 10 and a support plate 20.

[0017] The music sheet receiving plate 10 is a horizontally long rectangular plate-like member, and the back surface of a music sheet (not shown) is received by the music sheet receiving surface 11 on its surface. Therefore, the horizontal width of the music sheet receiving plate 10 has a length longer than that in a state where the music sheet is spread out. Also, the height is set to be higher than the height of the music sheet.

[0018] The music sheet receiving plate 10 can be made of various materials, but resins such as plastics or metals are preferable, and in particular, resins such as polypropylene are preferable. For example, a plastic corrugated board made of polypropylene resin may be used.

[0019] Note that the two upper corners of the music sheet receiving plate may be rounded, for example. In FIG. 1, the two upper corners of the music sheet receiving plate 10 are rounded and have a curved configuration instead of being right-angled.

[0020] Also, side covers 15 that cover the edges of the music sheet receiving plate 10 are provided at the upper side and the left and right side edges of the music sheet receiving plate 10. This is provided for the purpose of protecting the side surface of the music sheet receiving plate 10 and not damaging the grand piano. However, the side covers 15 are not essential and may be provided as necessary.

[0021] The side covers 15 can be made of various materials as long as they have a protective function. For example, they may be made of materials having elasticity such as synthetic rubber or rubber. For example, a configuration may be adopted in which the peripheral portion of the music sheet receiving surface 10 is made of a metal such as steel and is covered with the side cover 15 made of synthetic rubber including that portion.

[0022] Since FIG. 3 is easier to understand than FIG. 1 for the support plate 20, it will be described with reference to FIG. 3.

[0023] FIG. 3 is a side view of the auxiliary music stand 50 according to an 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] As shown in FIG. 3, the support plate 20 is a plate-like member that supports the music sheet receiving plate 10 from below. The front surface side (front side) of the support plate 20 protrudes forward to form a front protruding portion 21, and the back surface side of the support plate 20 protrudes rearward to form a rear protruding portion 22.

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

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

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

[0028] Since the back surface of the music sheet receiving plate 10 is not the surface on which the music sheet is received, it does not need to be a flat surface, and the clamping portion 30 is provided.

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

[0030] The clamping portion 30 is an attachment mechanism for fixing the auxiliary music stand 50 to a plate-like structure. The clamping portion 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 extending substantially horizontally in the lateral direction, the upper clamping portion 31 and the lower clamping portion 32 can sandwich the plate-like structure from above and below and attach it to the plate-like structure.

[0031] For example, when the keyboard cover of a grand piano is fully opened and lifted upward, the tip of the keyboard cover, that is, the part that is positioned at the lowest level when the keyboard cover is closed, has a shape that protrudes substantially horizontally. The holding part 30 can be attached so as to sandwich the most protruding and substantially horizontally extending part from above and below, and the auxiliary music stand 50 can be fixed.

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

[0033] The holding part 30 is preferably composed of a material having a certain degree of elasticity, and is preferably composed of a metal, a resin, or an elastic body such as rubber or synthetic rubber. This is because a material having appropriate elasticity can make the holding force between the upper holding member 31 and the lower holding member 32 large enough. For example, the holding part 30 may be composed of a metal such as steel and covered with an elastic body such as synthetic rubber around it. Thereby, both strength and elasticity can be ensured.

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

[0035] As shown in FIG. 3, the support plate 20 extends horizontally in the front-rear direction, and the music stand receiving plate 10 extends vertically and independently thereon. That is, the support plate 20 serves to support the music stand receiving plate 10.

[0036] Since the front (front side) of the support plate 20 extends greatly and will interfere with viewing the music score, on the front side, it extends short enough to stably hold the music score. On the other hand, since the back side of the support plate 20 will not interfere even if it extends greatly rearward, it extends greatly to secure a length and area sufficient to support the music stand receiving plate 10.

[0037] In this way, the auxiliary music stand 50 according to the present embodiment stands on its own with a vertically extended shape, and since the rearward extension width of the rear protrusion 22 and the rearward extension width of the clamping portion 30 are not large, it has a thin shape as a whole, and the storage when not in use is a space-saving configuration.

[0038] The music sheet receiving plate 10 has a front surface on the left side that constitutes the music sheet receiving surface 11 and functions as a surface for receiving the back surface of a music sheet (not shown). Also, the upper surface 21a of the front protrusion 21 protruding forward from the support plate 20 constitutes a music sheet support portion for supporting the lower end of a music sheet (not shown).

[0039] A clamping portion 30 is provided at the lower part of the back surface of the music sheet receiving plate 10. As described with reference to FIG. 2, the clamping portion 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 sandwich a plate-like member from above and below.

[0040] Among the clamping portion 30, the upper clamping member 31 has a shape that extends greatly rearward because it receives the weight of the auxiliary music stand 50 and thus more load is applied. On the other hand, the lower clamping member 32 does not bear the load of the auxiliary music stand 50 and only needs to be able to sandwich the end of the keyboard cover to fix the position, so it has a shorter configuration than the upper clamping member 31.

[0041] The tip 31a of the upper clamping member 31 has a shape that is slightly open upward, and the tip 32a of the lower clamping member 32 has a shape that is slightly open downward. This is to facilitate the attachment of the clamping portion 30 to the keyboard cover of the piano, making it easier for the keyboard cover to enter the groove inside the clamping portion 30 and enabling the smooth fixed installation of the auxiliary music stand 50. Thereby, the installation of the auxiliary music stand 50 on the grand piano can be easily carried out in a short 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 keyboard cover of the grand piano. This is to securely hold the keyboard cover of the grand piano and not clamp it with excessive stress.

[0043] As shown in FIG. 2, it is preferable that a plurality of clamping portions 30 are provided at intervals in the left - right direction. As shown in FIG. 2, for example, if they are provided in pairs, one on each side, the auxiliary music stand 50 can be securely fixed.

[0044] However, the number of the clamping portions 30 is not limited to two, and may be three or more, or there may be a structure in which only one clamping portion 30 with a long horizontal length is provided. The number of the clamping portions 30 can be set to any number according to the application as long as the auxiliary music stand 50 can be fixed to the keyboard cover of the grand piano.

[0045] Also, the height position of the clamping portion 30 is provided below the middle in the height direction of the back surface 11 of the music stand plate 10 in FIGS. 1 and 3 of the present embodiment. However, when it is desired to make the height of the music stand even lower, the clamping portion 30 may be provided at the middle height or at a height above the middle. Thus, the mounting height of the clamping portion 30 can be set to any height according to the application.

[0046] Next, with reference to FIGS. 4 to 9, a method for attaching the auxiliary music stand 50 according to the present embodiment to a grand piano will be described.

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

[0048] The keyboard of the grand piano 100 is covered with a keyboard cover 110. The keyboard cover 110 has a horizontally extending upper surface cover portion 111 that covers the upper part of the keyboard and a side surface cover portion 112 that extends downward and covers the side surface of the keyboard, and its cross - sectional shape is configured as a substantially L - shape with rounded corners.

[0049] Behind the keyboard cover 110, a portion called the front frame 130 is provided. Further behind the front frame 130, there is a portion where strings are stretched (not shown).

[0050] Figure 5 is a view showing the state where the keyboard cover 110 of the grand piano 100 is fully opened. By lifting and opening the keyboard cover 110 upward, the keyboard 120 is exposed. In this state, the grand piano 100 is played.

[0051] When the keyboard cover 110 is lifted and opened upward, the upper cover portion 111 of the keyboard cover 110 stands up vertically, and the side cover portion 112 extends horizontally in a substantially horizontal state. And the tip of the side cover portion 112, that is, the end portion that comes to the lowest position when the keyboard cover 110 is closed, protrudes forward, and the tip 112a comes to the position closest to the performer. Also, the tip 112a of the keyboard cover 110 and the front frame 130 are arranged in proximity.

[0052] Figure 6 is a view showing the state where the auxiliary music stand 5050 is being aligned before being attached to the grand piano 100.

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

[0054] Figure 7 is a view showing the state where the auxiliary music stand 50 is installed on the grand piano 100. The auxiliary music stand 50 is moved until the clamping portion 30 of the auxiliary music stand 50 sandwiches the side cover portion 112 of the keyboard cover 110 from the tip 112a 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 keyboard cover 110.

[0055] Note that in the auxiliary music stand 50 according to the present embodiment, since the clamping portions 30 are provided on the left and right, the auxiliary music stand 50 is pushed in so that the tips 112a of the side cover portions 112 of the keyboard cover 110 reach the depths of the clamping portions 30 on both the left and right sides, and is attached to the keyboard cover 110.

[0056] The music stand originally installed on a normal grand piano is provided so as to extend upward from the height of the front frame 130. Therefore, the height of the music stand is too high for children such as infants and elementary school students, and it is difficult to visually recognize. However, by installing the auxiliary music stand 50 according to the present embodiment, the height at which the music score is held can be lowered, and the music score can be arranged near the keyboard 120. Therefore, even children with a low seat height can easily view the music score.

[0057] In addition, since the installation of the auxiliary music stand 50 is completed only by attaching it to the tip 112a of the open keyboard cover 110, the attachment work can be easily performed by hand, and the auxiliary music stand 50 can be installed with little labor in a short time. Specifically, the attachment is completed in an instant and can be attached in about 1 second.

[0058] FIG. 8 is a diagram for explaining a 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 additional fixing member 40 is installed on the grand piano 100. The fixing member 40 is a regulating member for preventing the keyboard cover 110 from closing and fixing the keyboard cover 110 in a fully open state. The fixing member 40 has a U-shape and is inserted between the inside of the front frame 130 (the side opposite to the keyboard 120, that is, the string side) from above and the tip 112a of the side cover portion 112 of the keyboard cover 110 and clamped from the outside to regulate the movement of the keyboard cover 110. Thereby, the state in which the keyboard cover 110 is fully open can be reliably maintained. Since children often use the auxiliary music stand 50 as performers, by using the fixing member 40, the risk of the keyboard cover 110 closing can be eliminated, and the grand piano 100 can be played safely.

[0059] FIG. 9 is a diagram showing an example of the installation method of the fixing member 40. As shown in FIG. 9, the fixing member 40 has a U-shape, and the keyboard cover 110 can be fixed by installing the fixing member 40 from above so as to sandwich the front frame 130 and the tip 112a of the keyboard cover 110 from the outside.

[0060] In FIGS. 8 and 9, the fixing member 40 is configured in a just-fit shape that exactly matches the distance between the front frame 130 and the tip 112a of the keyboard cover 110. However, it may be configured to have a little more margin in the horizontal part, and the extra part may be raised upward to form an arch shape.

[0061] The fixing member 40 is preferably made of a material having a certain degree of elasticity, such as an elastic body such as metal, resin, or synthetic rubber. This makes it possible to fix the keyboard cover 110 without applying extra stress to the grand piano 100. For example, the fixing member 40 may be configured by covering a metal material such as steel with an elastic body such as synthetic rubber.

[0062] Also, the fixing member 40 may have different lengths of the portions extending in the vertical direction that are hung on the front frame 130 and the tip 112a of the keyboard cover 110. For example, it may be configured such that the length of the portion extending in the vertical direction that is hung on the tip 112a of the keyboard cover 110 is longer than the portion extending in the vertical direction that is hung on the front frame 130. This is because the front frame 130 side of the fixing member 40 mainly plays a role in position fixing, while the tip 112a side of the keyboard cover 110 mainly plays a function as a stopper so that the keyboard cover 110 does not drop, and it may be configured to be long in consideration of the thickness of the side cover portion 112 of the keyboard cover 110.

[0063] Also, in FIGS. 8 and 9, an example using two fixing members 40 is described. However, depending on the application, one may be used, or more than two may be used. However, using two fixing members 40 as a left and right pair is preferably balanced in terms of high safety and less installation effort.

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

[0065] In this way, the auxiliary music stand 50 and the fixing member 40 constitute an auxiliary music stand set. Although the purpose of making the music score easier to view by bringing it closer to the eyes can be achieved with only the auxiliary music stand 50, by configuring it as an auxiliary music stand set with the addition of the fixing member 40, the keyboard lid 110 can be fixed in a fully open state, ensuring safety.

[0066] Also, the auxiliary music stand 50 and the 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 grand piano 100. By specifying the individual sizes and arrangements of the auxiliary music stand 50 and the auxiliary music stand set according to the size of each grand piano 100 and the physique of the performer, a configuration more suitable for individual uses can be achieved.

[0067] As described above, the preferred embodiments of the present invention have been described in detail. However, 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 an auxiliary music stand, and is particularly suitable for use as an auxiliary music stand for a grand piano.
