TECHNICAL FIELD OF THE INVENTION
The present invention relates to a music stand for a piano, and more particularly to a music stand for supporting a music stand body by locking a torii attached to the music stand body into a locking groove of the original wood, such as that provided on a grand piano or the like. Music stand.
[0002]
[Prior art]
FIG. 5 shows a music stand of a conventional grand piano of this type. The music stand 51 is fixed between the left and right book holding plates 2, the front and rear book holding sticks 3, 4 fixed between the book holding plates 2, 2, and the book holding sticks 3, 4. Left and right original wood 5 are provided, and a plurality (three in this example) of locking grooves 6 are formed at the rear of each original wood 5 so as to be arranged in the front-rear direction. I have. The music stand 51 includes a music stand main body 7 and a torii 58. The music stand main body 7 is rotatably attached at its lower end to the front main body rod 3 via a music stand hinge 9. The torii gate 58 is of a reverse gate type, and has left and right legs 61, 61 rotatably attached at one end to the back surface of the music stand main body 7 via a torii hinge 60, and the left and right legs 61, 61. And a cross member 62 connected between the other ends. A cushion 62a made of felt or the like is attached to left and right ends of the cross member 62.
[0003]
The music stand 51 further includes left and right music stand receiving members 63, 63. Each of the music stand holders 63 includes a support 64, a receiver 65 rotatably mounted on the support 64 via a pin (not shown), and a cushion 66 mounted on the surface of the receiver 65. It is composed of The support tool 64 and the receiving tool 65 are made of an iron plate or the like, and the cushion 66 is made of felt or the like. The music stand holder 63 is fixed to the rear support rod 4 at the support 64, and the holder 65 is moved between the standing position (solid line in the figure) and the falling position (dashed line in the figure). It is pivotable.
[0004]
With this configuration, in the music stand 51, as shown in FIGS. 6A and 6B, the portion of the torii 58 to which the cushion 62 a of the horizontal member 62 is attached is engaged with the locking groove 6 of the original wood 5. By stopping, the music stand main body 7 is supported in an oblique posture, and the angle A of the music stand main body 7 is adjusted by changing the locking groove 6 to be locked. The angle A of the music stand main body 7 becomes maximum (for example, about 65 degrees) when the locking cross member 62 of the torii 58 is locked in the locking groove 6 at the frontmost position (FIG. 7A), It becomes minimum (for example, about 55 degrees) when it is locked in the locking groove 6 at the position (FIG. 9B).
[0005]
When performing an ensemble performance with another musical instrument such as a violin, the music stand main body 7 should be set so that the angle A is considerably smaller than the above so that the player can see it (hereinafter referred to as "small"). Angle setting ”) is preferable, in which case the music stand holder 63 is used. That is, as shown in FIG. 6C, the music stand main body 7 is tilted rearward while the torii 58 is folded, and the receiving stand 65 of the music stand holder 63 is positioned at the upright position. By making contact, the angle A of the music stand main body 7 can be made considerably small (for example, about 30 degrees).
[0006]
[Problems to be solved by the invention]
However, in the conventional music stand 51, as described above, the angle A of the music stand 7 can be adjusted only in three stages by simply changing the locking groove 6 of the original wood 5 for locking the torii 58. Since the adjustment range is narrow, about 55 to 65 degrees, left and right music stand holders 63, 63 are separately required for setting a small angle when performing an ensemble performance or the like. For this reason, the material cost and the assembly cost of the music stand holder 63 are extra, and the work of attaching the assembled music stand bracket 63 to the main holding rod 4 is also required, and the manufacturing cost increases accordingly. .
[0007]
The present invention has been made in order to solve such a problem, and provides a music stand for a piano that can reduce the manufacturing cost by reducing the number of parts and can also set a small angle of the music stand main body. It is aimed at.
[0008]
[Means for Solving the Problems]
In order to achieve this object, a music stand of a piano according to the present invention has front and rear main holding rods extending in the left and right direction and a plurality of locking grooves arranged in parallel in the front and rear direction on an upper surface. A Motomoto tree extending between the rods, a music stand main body whose lower end is rotatably supported by the front Motoyo rod, and a torii gate for supporting the music stand main body to the Motogi tree. The torii gate has a first leg portion rotatably attached to a music stand main body, an upper end portion rotatably connected to a lower end portion of the first leg portion, and a lower end side of the first leg portion. Left and right legs respectively having a second leg portion rotatable between a deployed position extending linearly and a folding position that is folded with respect to the first leg portion, and a second leg of the left and right legs. A lower end of the torii gate when the second leg is in the deployed position and the folded position. It is characterized by being lockably configured to any one of the grooves.
[0009]
According to the music stand of the piano, the right and left legs of the torii gate are each formed into a first leg portion and a second leg portion which are rotatable with respect to each other, and the second leg portion is connected to the first leg portion. On the other hand, it is possible to take two positions, that is, a deployed position that extends linearly and a folded position that is folded. Further, the lower end of the torii gate can be locked in any one of the plurality of locking grooves of the original tree, regardless of whether the second leg is located at the deployed position or the folded position. Therefore, the angle of the music stand main body can be adjusted by the number of steps equal to the number of positions of the second leg (= 2) × the number of locking grooves, and the number of adjustment steps can be doubled as compared with the related art. .
[0010]
More specifically, when performing a normal performance such as piano solo, the lower end of the torii gate is connected to one of the mochimotoki with the second leg positioned at the deployed position and the leg extended. By selectively engaging the locking grooves, the music stand main body can be set at a normal use angle (hereinafter referred to as “normal angle setting”), and can be adjusted with the number of steps equal to the number of locking grooves. On the other hand, when performing an ensemble performance, the lower end of the torii gate is selectively locked in one locking groove while the second leg is positioned at the folded position and the leg is contracted. In addition, the angle of the music stand main body can be considerably reduced, the small angle of the music stand main body can be set, and the angle of the music stand main body can be adjusted by the number of steps equal to the number of locking grooves.
[0011]
As described above, the music stand of the present invention has a simple configuration in which the torii legs are simply divided into two parts, so that not only a normal angle setting but also a small angle setting of the music stand main body is possible. The music stand bracket that was provided becomes completely unnecessary. Therefore, the manufacturing cost can be reduced by reducing the material cost and the assembly cost.
[0012]
In this case, the first leg and the second leg are in contact with each other when the second leg is in the deployed position, so that the second leg is opposite to the folding position with respect to the extension of the first leg. It is preferable to have an end face positioned at the side angular position.
[0013]
According to this configuration, when the second leg is in the unfolded position, the end surfaces of the two legs are in contact with each other in a state where the second leg is at an angle to the first leg on the side opposite to the folded position, Since the two legs are pressed against each other, it is possible to prevent the second leg portion at the deployed position from breaking toward the folding position, and to stably maintain the posture.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a music stand of a grand piano to which the present invention is applied. Note that, of the components of the music stand 1, those having the same configuration as the conventional music stand 51 described above are denoted by the same reference numerals.
[0015]
Like the conventional music stand 51, the music stand 1 includes left and right book holding plates 2, 2, front and rear sticks 3, 4 fixed between the book holding plates 2, 2, and a book holding stick 3. , 4 and a plurality of (in this example, three) locking grooves 6 are provided at the rear portion of each of the original holding trees 5, 5. Are formed side by side. The music stand 1 includes a music stand main body 7 similar to the music stand 51. The music stand main body 7 has a lower end portion on the back of the front main body rod 3 via three music stand hinges 9. It is rotatably mounted.
[0016]
A torii gate 8 according to the present invention for attaching the music stand main body 7 to the back of the music stand main body 5 is attached to the back of the music stand main body 7. The torii gate 8 has a reverse gate shape, and includes left and right legs 11, 11 and a horizontal member 12 connected between the legs 11, 11. The interval between the legs 11, 11 is set substantially equal to the interval between the left and right original holding trees 5, 5. As shown in FIG. 2, each leg 11 has a two-part configuration including an upper first leg 11 a and a lower second leg 11 b, and the ends of both 11 a and 11 b are connected via a hinge 13. Are rotatably connected to each other. The upper end of the first leg 11a is rotatably attached to the back of the music stand main body 7 via the torii hinge 10, and the cross member 12 is connected between the left and right second legs 11b, 11b. I have. The first and second legs 11a and 11b and the cross member 12 are made of a solid wood material as in the related art. The hinge 13 is preferably the same color as the first and second legs 11a and 11b in harmony with these.
[0017]
With the above configuration, the second leg 11b is in a deployed position (see FIG. 4A) that extends substantially linearly with respect to the first leg 11a, and is in a folded position that is folded with respect to the first leg 11a. (See FIG. 2B). As shown in FIG. 3, the deployed position is regulated by the end faces 11c and 11d of the connecting portions of the first and second legs 11a and 11b being in contact with each other. As shown in the figure, the end faces 11c and 11d are formed slightly oblique, so that when the second leg 11b is in the deployed position, the second leg 11b is moved to the first leg. It is positioned at an angle position opposite to the folded position with respect to the extension of the portion 11a, and is held at a slight angle with the first leg portion 11b. Further, cushions 14 and 15 made of felt, artificial leather, or the like for preventing noise and scratches are attached to the periphery of the end faces 11c and 11d and the lower end of the second leg 11b, respectively.
[0018]
The music stand 1 having the above configuration is used as follows. That is, when performing a normal performance such as a solo performance of a piano, as shown in FIG. 4 (a), with the second leg 11b positioned at the deployed position and the leg 11 extended, the left and right second legs are extended. The lower ends of the portions 11b, 11b are locked in one locking groove 6, 6, respectively, of the left and right original holding trees 5, 5. Thereby, the music stand main body 7 is set at the normal angle setting. Further, by changing the locking groove 6 to be locked, the angle A of the music stand main body 7 can be adjusted in three stages equal to the number of the locking grooves 6. The adjustable angle range in this case is about 55 to 65 degrees as in the related art.
[0019]
In this state, as described above, the second leg 11b is located on the side opposite to the folding position with respect to the extension of the first leg 11a, and has a slight angle with the first leg 11a. Therefore, it is possible to prevent the second leg 11b from being bent toward the folding position, and to stably hold the posture. Further, when the second leg portion 11b is locked in the locking groove 6, the second leg portion 11b comes into contact with the locking groove 6 via the cushion 15 attached to the lower end thereof, so that noise and scratches at that time are prevented. Can be.
[0020]
On the other hand, when performing an ensemble performance, as shown in FIG. 4 (b), the second leg portion 11b and the cross member 12 connected to the second leg portion 11b are positioned at the folded position and the leg 11 is contracted. Then, the lower ends of the left and right first legs 11a, 11a are locked in the locking grooves 6, 6, respectively, of the original holding trees 5, 5. Thereby, the music stand main body 7 is set with the small angle setting. Also, by changing the locking groove 6, the angle A of the music stand main body 7 can be adjusted in three stages. The adjustable angle range in this case is, for example, about 25 to 35 degrees. Further, similarly to the above, the generation of noise and scratches when the first leg 11a is locked in the locking groove 6 is prevented by the cushion 14.
[0021]
As described above, according to the music stand 1 of the present embodiment, each leg 11 of the torii 8 is divided into the first and second legs 11a and 11b, and the second leg 11b is formed of the first leg 11b. 11a, it is possible to take two positions, an unfolded position and a folded position, and at any one of these positions, it can be locked to any one of the plurality of locking grooves 6 of the original wood 5. is there. Accordingly, the angle A of the music stand main body 7 can be adjusted by the number of steps equal to the number of positions of the second leg 11b (= 2) × the number of the locking grooves 6, and the number of adjustment steps is smaller than that of the conventional art. Can be doubled. The normal angle setting of the music stand main body 7 can be performed in a state where the second leg 11b is located at the deployed position, and the music stand main body 7 can be set in a state where the second leg 11b is located at the folded position. Since a small angle can be set, a music stand bracket conventionally provided is completely unnecessary. Therefore, the manufacturing cost can be reduced by reducing the material cost and the assembly cost.
[0022]
Note that the present invention can be implemented in various aspects without being limited to the embodiments described above. For example, in the embodiment, when the second leg 11b is in the unfolded position and the folded position, the second leg 11b and the first leg 11a are locked in the locking groove 6 of the original wood 5 respectively. However, the width of the horizontal member 12 may be substantially the same as the length of the second leg 11b, and the horizontal member 12 may be locked in the locking groove 6 at any of the deployed position and the folded position. In addition, the number of the locking grooves 6 of each of the original holding trees 5 is not limited to three in the embodiment, and may be increased further.
[0023]
Further, although the embodiment is an example in which the present invention is applied to a grand piano, the present invention can be applied to other types of pianos, for example, a grand piano-type electronic piano, if appropriate. In addition, the configuration of the details can be appropriately changed within the scope of the present invention.
