Description

  The present invention relates to a music stand device provided in a keyboard instrument or the like.

  2. Description of the Related Art Conventionally, there is known a music stand device in which a music plate is erected on a mounting table such as a roof plate of a keyboard instrument (for example, Patent Document 1 below). This apparatus has a mounting plate fixed to the mounting table, a fixing plate fixed to the musical score plate, and a support plate pivotally supported on the upper end of the fixing plate, and the free end of the support plate is engaged with the mounting plate. These three members form a triangular shape when viewed from the side, and the musical score plate is maintained in a standing state in which the music plate is slightly tilted back. The mounting plate is fixed to the mounting table with screws or the like.

Japanese Patent No. 3317109

  However, in the music stand device of the above-mentioned Patent Document 1, when the mounting plate is fixed to the mounting table, the fixing work is usually performed from above with a work tool such as a driver, but is erected above the fixing portion. Since the upper end portion of the music score board exists, the work tool and the music score board easily interfere with each other as it is, and it is difficult to perform the fixing work. For this reason, it is usually necessary to raise the music score board once forward. For this reason, it is necessary to provide an appropriate gap between the lower end surface and the mounting table so that the lower end surface of the musical score plate at the time of standing (the front end surface when tilting) does not interfere with the mounting table. . Due to the presence of such a gap, there is a risk that fingers or foreign objects may be caught in this gap during fixing work or music board standing / falling operation, which is not safe and does not look good from the front. was there.

  Alternatively, if the front and rear lengths of the mounting plate are formed long enough and the fixing part is disposed at the rear of the mounting plate, interference between the work tool and the music score plate during the fixing work can be avoided, but the mounting plate is large. Not only does the workability deteriorate, but the fixing strength of the mounting plate with the mounting table mainly at the front portion becomes weak and the fixing state is not stable.

  Moreover, in the music stand apparatus of the said patent document 1, since the music reception part is provided on the roof board which is a mounting base, the music score position is comparatively high and there existed room for improvement in the point of visibility.

  By the way, a keyboard instrument provided with a slide opening / closing lid that slides back and forth is generally configured such that the inside of the instrument body is blinded by the slide opening / closing lid so that the inside of the instrument body cannot be seen when the lid is closed. However, in this case, since the longitudinal length of the slide opening / closing lid becomes long, there is a problem that the depth of the instrument main body becomes long as a result in order to secure a storage space for the slide opening / closing lid when the lid is opened. On the other hand, if a member is separately provided only for blinding the inside of the musical instrument main body, not only the configuration is complicated, but also the appearance is not good.

  An object of the present invention is to enable the musical score receiving portion to perform a blindfold function inside the musical instrument main body, shorten the depth of the musical instrument main body having the slide opening / closing lid, and improve the appearance of the keyboard musical instrument without complicating the configuration. It is in providing the music stand apparatus which can do.

  In order to achieve the above object, a music stand device according to claim 1 of the present invention is a music stand device provided in a keyboard instrument having a slide opening / closing lid (42) that is opened and closed by sliding in the front-rear direction. A slide plate, a front plate portion (62) that is provided obliquely downwardly and downwardly from the front portion of the roof plate, and holds the back of the musical score (84); and when the slide open / close lid is closed, the slide opening / closing It has a music score receiving part (63) which is provided at a position to bridge the rear part (42a) of the lid and the lower part (62b) of the front plate part and holds the lower end of the music score.

  According to this configuration, the music score receiving part is provided at a position that bridges the rear part of the slide opening / closing lid and the lower part of the front plate part in the closed state, not only holding the lower end of the music score, Blind the inside of the instrument body. Therefore, since it is not necessary to lengthen the front and rear length of the slide opening / closing lid for blinding the inside of the instrument body, the storage space for the slide opening / closing lid at the time of opening the lid can be reduced, so that the depth of the instrument body can be shortened. it can. Moreover, compared with the case where a dedicated member for blindfolding is provided, the configuration is simple and the design is advantageous. Therefore, the musical score receiving portion can perform a blindfold function inside the musical instrument main body, the depth of the musical instrument main body having the slide opening / closing lid can be shortened, and the appearance of the keyboard musical instrument can be improved without complicating the configuration.

  In addition, the code | symbol in the said parenthesis is an illustration.

  According to the present invention, the musical score receiving portion can perform a blindfold function inside the musical instrument main body, the depth of the musical instrument main body having the slide opening / closing lid is shortened, and the appearance of the keyboard musical instrument is improved without complicating the configuration. be able to.

It is a side view (figure (a)) of the principal part of a music stand unit, a top view (figure (b)) of an attachment member, and a top view (figure (c)) of a musical score holding part.

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

  Fig.1 (a) is a perspective view of the upper half part of the keyboard musical instrument to which the music stand apparatus which concerns on one embodiment of this invention is applied. FIG. 1B is a right side view of the upper half of the keyboard instrument 1. FIG. 2 is an exploded view of the keyboard instrument body KBU and the roof unit RU.

  The keyboard instrument 1 is roughly formed by assembling a keyboard instrument body KBU and a roof unit RU to a support unit SU. Further, a music stand unit MSU is attached to the roof unit RU. Hereinafter, the front / rear and left / right directions of the keyboard instrument 1 and the music stand unit MSU will be referred to based on the player in the state where the music stand unit MSU is mounted.

  The keyboard instrument body KBU is disposed between the left and right side plates 41, the side plate 41 corresponding to the mountain plate, the back plate 46 connecting the rear portions of the left and right side plates 41, and the left and right side plates 41. And a lid 42 that covers the keyboard. In the keyboard instrument main body KBU, the right side and the left side are symmetrical and have the same configuration, and FIGS. 1B and 2 show the configuration on the right side.

  As shown in FIG. 2, one pinion gear 47 is attached to each of the left and right sides of the rear portion 42 a of the lid 42 in the keyboard instrument body KBU. In addition, one rack 48 corresponding to each pinion gear 47 and meshing with each pinion gear 47 is provided in the rear half of the keyboard instrument main body KBU (see also FIG. 1B). The lid body 42 is a slide opening / closing type. When the lid body 42 is urged forward and backward, the pinion gear 47 rolls on the corresponding rack 48 and the lid body 42 moves in the front-rear direction.

  As shown in FIGS. 1B and 2, abutting members 50 and 51 with which a front plate portion 62 (described later) of the roof unit RU abuts and a fixing member 43 are fixed inside the both side plates 41. ing. As shown in FIG. 2, a roof unit mounting bracket 44 for mounting the roof unit RU is attached to the fixing member 43.

  A holding hole 44a that is long in the front-rear direction is formed in the upper surface portion of the roof unit mounting bracket 44, and the front portion of the holding hole 44a is a wide and wide portion (details are not shown). Moreover, the upper surface part of the roof unit attachment bracket 44 becomes low as it goes back (refer FIG. 2). Engaging bolts 64 described later are engaged with the holding holes 44a, and play a part of the role of fixing the roof unit RU to the keyboard instrument main body KBU.

  As shown in FIG. 2, the roof unit RU includes a roof plate portion 61 and a front plate portion 62 that extends obliquely forward and downward from the front portion of the roof plate portion 61, and further, a lower portion of the front plate portion 62. The music score receiving member 63 is attached to the structure. In the roof plate portion 61, engagement bolts 64 corresponding to the roof unit mounting bracket 44 are attached to the lower surfaces of both left and right end portions via spacers 65. In addition, fixing metal fittings 66 are attached to the rear lower surfaces of the left and right ends of the roof plate portion 61. Further, one piece of a fixing bracket 67 having a “H” shape in a side view is fixed to the rear surface of the lower portion 62 b of the front plate portion 62 with two screws 52, and the musical score receiving member 63 is attached to the other piece of the fixing bracket 67. The lower surface is fixed with screws 69. The music score receiving member 63 serves to hold the lower end of the music score 84. At the same time, as will be described later, the musical score holding surface 79a of the musical score plate 79 and the front surface 62a of the front plate portion 62 cooperate to hold the rear surface of the musical score 84 (see FIG. 2).

  As shown in FIG. 1 (b), in the closed state of the lid body 42, the musical score receiving member 63 is located at a position that bridges the rear portion 42a of the lid body 42 and the lower portion 62b of the front plate portion 62, The inside of the keyboard instrument body KBU is blindfolded. Accordingly, it is not necessary to extend the rear portion 42a of the lid body 42 in the rearward direction in order to hide the inside of the keyboard instrument main body KBU, and the longitudinal length of the lid body 42 can be shortened. As a result of the small storage space for the lid 42, the depth of the keyboard instrument body KBU can be shortened. Further, the music score receiving member 63 also functions to hold the lower end of the music score 84, so that the configuration is not complicated as compared with the case where a dedicated member for blindfolding is provided. Further, the musical score receiving member 63 has a thickness (height) that is thicker toward the front part, which improves the appearance as viewed from the front.

  The music score receiving member 63 is disposed at a position sufficiently lower than the upper surface 61a of the roof plate portion 61, and the music score 84 is held at a lower position by that amount. Thereby, for example, the music score 84 can be held at a position that is lower and easier to see than when a music score receiving member is provided on the upper surface 61 a of the roof plate portion 61.

  The holding hole 44 a of the roof unit mounting bracket 44 is narrower than the head of the engaging bolt 64, and the wide portion of the holding hole 44 a is wider than the head of the engaging bolt 64. When the roof unit RU is assembled to the keyboard instrument body KBU, the head of the engagement bolt 64 is inserted into the wide portion of the holding hole 44a while moving the roof unit RU from the front to the rear, and the top of the side plate 41 is Slide the unit RU backward. Since the upper surface portion of the roof unit mounting bracket 44 is lowered toward the rear (see FIG. 2), the engagement bolt 64 and the holding hole 44a are engaged with each other as the roof unit RU is retracted. The 64 heads receive a downward urging force from the upper surface of the roof unit mounting bracket 44, whereby the roof unit RU is pressed against the side plate 41 side.

  Then, the roof unit RU is retracted until the fixing metal fitting 66 comes into contact with the back plate 46. At this time, the front plate portion 62 of the roof unit RU also contacts the contact members 50 and 51. In this state, the fixing unit 66 is screwed and fixed to the back plate 46, whereby the roof unit RU is assembled to the keyboard instrument body KBU. A monitor speaker 68 (68L, 68R) is housed in the lower portion 62b of the front plate portion 62 (see also FIG. 1B).

  The music stand unit MSU is detachably attached to the upper surface 61a of the roof plate portion 61 (see FIG. 1B). As shown in FIG. 2, the music stand unit MSU includes a folding music score board 79, an attachment member 71, a fixing member 72, and a support member 73. As shown in FIG. 2, the musical score plate 79 is used in a standing state slightly tilted (hereinafter simply referred to as “standing state”) and holds the musical score 84. In the standing state, the attachment member 71, the fixing member 72, and the support member 73 have a triangular shape in a side view, and these constitute the musical score plate support device 70. As shown in FIG. 1, the musical score board support device 70 has the same configuration at the left and right ends of the musical score board 79. Accordingly, only the configuration of one of the music board support devices 70 will be described.

  The music score receiving member 63 is provided with a music score presser 80 (80L, 80R). As shown in FIG. 1, the music score holding portions 80 </ b> L and 80 </ b> R are arranged on the music score receiving member 63 at positions inside the both ends of the music score plate 79 in the left-right direction.

  3A is a side view of the main part of the music stand unit MSU, FIG. 3B is a plan view of the mounting member 71, and FIG. 3C is a plan view of the music score holding portion 80 (80R). Since the music score holding portions 80L and 80R are similarly configured symmetrically, the configuration of the right music score holding portion 80R will be described as a representative of the music score holding portion 80 with reference to FIG.

  First, as shown in FIG. 3A, in the musical score board support device 70, one end portion 72 a of the fixing member 72 and one end portion 71 a of the mounting member 71 are pivotally supported by the rotation shaft portion 74. The other end portion 72 b of the support member 73 and the one end portion 73 a of the support member 73 are pivotally supported by the rotation shaft portion 75. The other end portion 71b of the attachment member 71 is provided with a locking portion 71c that is bent upward. The fixing member 72 is fixed to the back surface (rear surface) of the musical score plate 79 with a screw 78. The attachment member 71 is fixed to the upper surface 61 a of the roof plate portion 61 with an engagement bolt 76 and a screw 77. As a result, the musical score plate 79 is rotatable with respect to the roof plate portion 61 around the rotation shaft portion 74. The support member 73 rotates about the rotation shaft portion 75, and the free end portion 73 b is engaged with the engagement portion 71 c of the attachment member 71, thereby supporting the musical score plate 79. At this time, the musical score plate support device 70 has a triangular shape in a side view, and the musical score plate 79 is erected.

  The engagement bolt 76 has a neck portion 76b and a head portion 76a having a larger diameter than the neck portion 76b projecting from the upper surface 61a of the roof plate portion 61, and the head portion 76a is lifted from the upper surface 61a by the amount of the neck portion 76b. Screwed into the plate portion 61. As shown in FIG. 3B, the mounting member 71 is provided with a gourd-shaped engaging hole 71 d in a plan view at a position corresponding to the engaging bolt 76. The engagement hole 71d is formed by connecting a large hole 71d1 having a larger diameter than the head portion 76a of the engagement bolt 76 and a small hole 71d2 having substantially the same diameter as the neck 76b of the engagement bolt 76, and the large hole 71d1 is rearward. positioned. In addition, two fastening holes 83 for screwing screws 77 are provided at the rear portion 71b of the attachment member 71 and behind the engagement holes 71d.

  The music stand unit MSU is usually mounted after the roof unit RU is assembled to the keyboard instrument body KBU. The music stand unit MSU is attached to the roof unit RU as follows.

  That is, first, the free end portion 73b of the support member 73 is locked to the locking portion 71c of the mounting member 71, and the music plate support device 70 is in a triangular shape when viewed from the side (the music plate 79 corresponds to the standing state). In this state, the head portion 76a of the engagement bolt 76 is passed through the large hole 71d1 of the engagement hole 71d, and the attachment member 71 is brought into contact with the upper surface 61a of the roof plate portion 61. Next, in the above state, the music stand unit MSU is slid rearward on the upper surface 61a, and the neck portion 76b of the engagement bolt 76 is engaged with the small hole 71d2 of the engagement hole 71d. When the small hole 71d comes into contact with the rear end of the neck portion 76b, the small hole 71d2 and the neck portion 76b are fitted, and the position of the music stand unit MSU is substantially appropriate. In addition, the gap between the head portion 76a of the engagement bolt 76 and the upper surface 61a of the roof plate portion 61 is set to be substantially the same as the thickness of the mounting member 71, whereby the small hole 71d2 and the neck portion 76b are fitted. At this time, the head portion 76a of the engagement bolt 76 plays a role of simply fixing the attachment member 71.

  Thereafter, the rear portion 71 b of the attachment member 71 is screwed and fixed to the roof plate portion 61 with screws 77 through the fastening holes 83. This fixing work is performed, for example, by inserting a screwdriver into the head of the screw 77 from above and rotating it. Here, since the fastening hole 83 is located at the rear portion 71b of the attachment member 71, as shown in FIG. 2, the rear portion of the upper portion of the musical score plate 79, which is the rearmost portion of the musical score plate 79 in the standing state, is provided. The rearmost portion of the edge 79b is substantially located on the extension line L1 in the vertical direction of the fastening hole 83 to the screw 77.

  Here, as shown in FIG. 1, the musical score plate 79 is fan-shaped when viewed from the front, that is, the upper portion of the musical score plate 79 is formed in an arc shape when viewed from the front, and the length in the vertical direction when standing is in the horizontal direction. The center is the longest, and the shorter it goes to the left and right. Therefore, when the music score plate 79 is erected, the upper end rear edge 79b of the music score plate 79 is positioned forward as it is closer to the left and right ends. Therefore, as shown in FIG. 3B, the upper end rear edge 79 b of the musical score plate 79 is sufficiently forward of the center position of the fastening hole 83 when viewed only vertically above the fastening hole 83. . Therefore, the music score board 79 does not exist on the extension line L1 in the vertical direction of the fastening hole 83 to the screw 77.

  For this reason, the screw and the music score plate 79 do not interfere with each other during the screwing operation of the screw 77, and the fixing operation from above can be performed without any trouble. In this way, the music stand unit MSU can be mounted while maintaining the standing state without raising the music score plate 79 once. In addition, since the musical score board support device 70 is disposed at positions near the left and right ends of the fan-shaped musical score board 79, the position of the fastening hole 83 can be secured in order to avoid interference between the driver and the musical score board 79. Can be positioned as far as possible, that is, the depth of the mounting member 71 can be set short. From the viewpoint of further facilitating the screwing operation of the screw 77 by a driver or the like, it is desirable that the position of the fastening hole 83 is sufficiently behind the rearmost part of the musical score plate 79 in the standing state.

  By the way, the attachment member 71 and the fixing member 72 are formed in a plate shape. Although the support member 73 is also configured in a plate shape, when the free end portion 73b is locked to the locking portion 71c of the mounting member 71, a portion of the support member 73 located above the screw 77 has a meat portion. It is formed so that it does not exist and does not interfere with driver operation. Note that the support member 73 may be a rod-shaped member as long as the support member 73 is configured to avoid the position of the screw 77.

  Since the engagement hole 71d is located in the front half of the attachment member 71 and the fastening hole 83 is located in the rear portion 71b of the attachment member 71, when the attachment member 71 is fixed to the roof plate portion 61, the front-rear balance It is stable without wobbling even if it receives a force in the front-rear direction. Therefore, the standing state of the musical score plate 79 is more stably maintained as compared with the case where the attachment member 71 is fixed only at the rear portion (only with the screw 77).

  Here, as shown in FIG. 3A, the lower end surface 79 c of the musical score plate 79 forms an acute angle with respect to the musical score holding surface 79 a which is the front surface of the musical score plate 79. Further, in the standing state of the musical score plate 79, the lower end surface 79c of the musical score plate 79 and the upper surface 61a of the roof plate portion 61 are substantially parallel, and a small gap S1 is generated between them. Since the gap S1 is small, and it is not necessary to raise the musical score board 79 forward when the mounting member 71 is fixed to the roof board portion 61, a finger or a foreign object is not caught in the gap S1, and the music stand unit is safe. MSU installation work is also easy. In addition, since the gap S1 is small, the design is good.

  As shown in FIG. 2, the musical score plate 79 can be tilted by releasing the locking with the locking portion 71 c of the supporting member 73, as shown in the folded musical score plate 79 (P 1) and the supporting member 73 (P 1). it can. At the time of locking and unlocking of the support member 73 with the locking portion 71c, as shown in the music score plate 79 (P2) in FIG. 2, it is necessary to raise the music score plate 79 slightly forward. Since the required displacement amount at that time is small, the gap S1 is also small. Since the gap S1 is small, there is little possibility that a finger or a foreign object is caught in the gap S1 even when the music score board 79 is erected / inverted.

  When the musical score plate 79 is set upright, as shown in FIGS. 2 and 3A, the musical score holding surface 79a of the musical score plate 79 and the front surface 62a of the front plate portion 62 are flush with each other. The music score holding surface 79a and the front surface 62a cooperate to hold the back surface of the music score 84. Therefore, there is no step in the middle of the surface that holds the music score 84 from behind, and the music score 84 can be appropriately held. In addition, in the state where the musical score 84 is not placed, the musical score holding surface 79a and the front surface 62a are flush with each other and the gap S1 is small. Moreover, the front end face of the monitor speaker 68 is also flush with the front face 62a of the front plate portion 62, contributing to the improvement of the appearance.

  As shown in FIG. 2, the music score holding portion 80 is housed in the music score receiving member 63. As shown in FIG. 3 (c), the music score presser 80 includes a finger-hanging recess 81 and a music score presser bar 82. The musical score presser bar 82 is rotated in the left-right direction by the rotating portion 82a, and the free end portion can be erected and inverted. As described above, the music score receiving member 63 is formed thick, and a space for interior of the music score pressing portion 80 is secured. Accordingly, the music score presser 80 does not protrude below the music score receiving member 63, and it is easy to provide the music score presser 80 so as not to interfere with the lid 42. That is, by forming the music score receiving member 63 thick, not only is the music score holding portion 80 arranged using the space effectively, but the music score receiving member 63 has a profound feeling and is good in design.

  According to the present embodiment, the music stand unit MSU is slid rearward while the music plate 79 is maintained in the standing state, and the neck portion 76b of the engagement bolt 76 is fitted into the small hole 71d2 of the engagement hole 71d. The attachment member 71 is configured to be fixed to the roof plate portion 61 with a screw 77 through the fastening hole 83, and the gap S1 between the lower end surface 79c of the musical score plate 79 and the upper surface 61a of the roof plate portion 61 is reduced. Therefore, the stable mounting of the music stand unit MSU can be performed safely and easily, and the appearance of the keyboard instrument 1 can be improved.

  Further, according to the present embodiment, the music score holding surface 79a of the music score board 79 and the front face 62a of the front plate portion 62 are flush with each other in the standing state of the music score board 79, and the rear face of the music score 84 cooperates. Therefore, there is no step on the surface for holding the musical score 84 from behind, the musical score 84 can be appropriately held and the appearance is also good. Moreover, since the music score receiving member 63 is disposed at a position lower than the upper surface 61a of the roof plate portion 61, the music score 84 can be held at a position that is low and easy to see.

  Also according to the present embodiment, the music score receiving member 63 is provided at a position that bridges the rear portion 42a of the lid 42 and the lower portion 62b of the front plate portion 62, and not only the function of holding the music score 84, Since the inside of the keyboard instrument main body KBU is blindfolded, it is not necessary to lengthen the front and rear length of the lid body 42. Therefore, in the keyboard device 1 having the slide opening / closing type lid body 42, the depth of the keyboard instrument body KBU Can be shortened. In addition, compared with the case where a dedicated member for blindfolding is provided, the configuration is simple, the design is advantageous, and the appearance is improved.

  Furthermore, since the music score holder 80 is housed in the thick music score receiving member 63, it is easy to provide the music score holder 80 without interfering with the lid 42, and not only can the placement space be used effectively, The appearance is also good due to the thickness of the receiving member 63.

  In this embodiment, when the music stand unit MSU is mounted, the music stand unit MSU is slid rearward to engage the neck portion 76b of the engagement bolt 76 with the small hole 71d2 of the engagement hole 71d. However, the moving direction of the music stand unit MSU is not limited to the rear side, and the configuration may be such that the shape of the engagement hole 71d is changed and moved in the left-right direction or the oblique direction.

  Note that the musical score receiving member 63 can perform the blindfolding function inside the keyboard instrument main body KBU and the depth of the keyboard instrument main body KBU is limited, for example, regardless of the presence of the music stand unit MSU. The front surface 62a of the part 62 may be extended, and the rear surface of the music score 84 may be held only by the front surface 62a.

  The musical score plate 79 is erected by locking the free end 73 b of the support member 73 to the locking portion 71 c of the mounting member 71, but the location where the free end 73 b is locked is the mounting member 71. As long as it is a part of the locking portion 71c.
