Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a playing table used for placing and playing a musical instrument such as a keyboard musical instrument, an electronic keyboard musical instrument, and a percussion musical instrument.

[0002]

[Prior art]

 A conventional pedestal is composed of rigid plywood or metal plate, and is formed into a trapezoidal shape with a top plate on which a musical instrument such as a piano is installed and legs supporting the top plate. The top plate and the legs are connected to each other directly in contact with each other. In addition, the bottom surface of the leg is directly grounded on the floor. This pedestal is always fixed and installed on the floor of the performance hall, or it is always stored in a storage place and lifted by hand before use to move to the performance hall as needed. I am trying to install it. At this time, if a heavy instrument such as a piano is installed on the playing table, the instrument will be carried separately from the playing table.

[0003]

[Problems to be solved by the device]

 According to the conventional play table, since the top plate and the legs are directly connected to each other in a state of being in contact with each other, for example, when a piano or the like is played, the vibration of the performance sound is transmitted through the play table. A part of the musical range is resonated with the floor surface when it reaches the floor surface of the performance hall, causing a problem that the performance sound becomes unclear. At the same time, noise from the floor is transmitted to the piano via the podium, and the noise and the sound of the piano in the same range resonate to express the delicate and subtle performance sound of the piano. There is a problem that you cannot do it.

Further, when the conventional pedestal is fixed and installed on the floor surface, there is a problem that it becomes an obstacle when the venue is used for purposes other than performance. Also, when installing by moving, since the lower surface of the legs is grounded directly to the floor, first move the playing table by lifting it manually, then the piano. It must be moved separately from the pedestal and finally the piano must be placed on the pedestal. In addition, when the pedestal and the piano are stored, the work must be performed in the reverse order of the above procedure, which requires a lot of trouble to move and install, which causes a problem.

The present invention has been made in order to solve such a problem, and prevents the propagation of the musical performance of the musical instrument to the floor surface and the noise of the performance hall to the musical instrument. It is an object of the present invention to provide a playing table which can realize a clear playing sound and can be easily moved and installed.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is provided with a base for placing a musical instrument on the upper surface and legs for supporting the base, and a contact portion between the leg and the base, It is characterized in that a vibration damping member is provided on at least one of the ground portion of the leg portion.

In this case, a vertical direction is provided between an extension position that projects downward from the lower end of the leg to support the stand and the leg, and a retracted position that retracts above the lower end of the leg. It is preferable to further include a traveling means capable of expanding and contracting.

[0008]

[Action]

 According to this playing table, a table for placing the musical instrument on the upper surface and a leg for supporting the table are provided, and a contact portion where the leg and the table come into contact with each other and a ground for the leg Since a vibration isolator is provided on at least one of the parts, when a musical instrument placed on the table is played, the vibration of the performance sound is transmitted from the instrument itself to the table, and from the table. Either the anti-vibration member provided at the contact part where the leg and the pedestal part come into contact with each other when it reaches the leg, or the anti-vibration member provided at the grounding part of the leg. Or both, the vibration of the performance sound is absorbed. On the other hand, the vibration of noise in the performance hall is also absorbed by one or both of the above-mentioned two vibration isolation members when being transmitted to the performance table along the floor surface.

【Example】

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

FIG. 1 is a side view showing an installed state of a performance table according to an embodiment of the present invention. FIG. 2 is a side view showing the performance table in a moving state. As shown in FIGS. 1 and 2, the playing table 1 of the present embodiment has a top plate (mounting table part) 2 on which a musical instrument and a player are placed, and a pair of front and rear legs 3 supporting the top plate 2. 3 and four traveling devices (traveling means) 4, 4 and 4 (only two are shown) provided at four corners of the pedestal 1 for moving the pedestal 1. A grand piano (hereinafter referred to as "piano") P and a chair C are installed on the pedestal 1 so that the player can play on it.

The top plate 2 is made of rigid plywood or metal, and has a rectangular plane. A first anti-vibration rubber (anti-vibration member) 5 is attached over the entire surface of the lower surface of the top plate 2 and the front and back surfaces of the top plate 2 that come into contact with the legs 3 (see FIG. 3). The first anti-vibration rubber 5 is made of synthetic rubber such as neoprene rubber or polypropylene rubber, and is formed in a thin plate shape. Further, a bearing plate 6 is attached to the lower surface of the top plate 2 from the center in the front-rear direction toward the leg portion 3. At the center of the bearing plate 6, a vertically long shaft hole 7 that axially supports one end of the traveling device 4 is formed.

As shown in FIG. 3, each leg portion 3 includes a leg body 8, a support square member 9 on which the top plate 2 is placed, and a support base 10 that supports the leg body 8.

The leg body 8 is made of plywood, metal or the like, and is formed in a rectangular shape extending in the lateral direction (the direction perpendicular to the drawing). A vertically long handle insertion opening 11 is formed in the center of the leg body 8 in the vertical direction. A plate-shaped second rubber vibration isolator (vibration isolator member) 12 and a cork 13 are attached to the lower surface of the leg body 8. The second anti-vibration rubber 12, like the first anti-vibration rubber 5, is made of synthetic rubber such as neoprene rubber. The cork 13 is used as a cushioning material.

The support members 9 are made of plywood, metal, or the like, and are arranged so as to extend horizontally in the horizontal direction. The support square 9 is firmly attached to the inner surface of the upper portion of the leg body 8 so as to project inward, and the top plate 2 is placed on the support square 9 via the first anti-vibration rubber 5.

The support base 10 is made of plywood, synthetic resin, metal such as aluminum, and the like, and has a support recess 14 opened at the top. The support concave portion 14 extends continuously in the lateral direction, and the lower end portion of the leg body 8 is inserted therein. The support 10 has a function of preventing the floor surface F from being damaged by the legs 3 of the performance table 1 and having a function of preventing slippage.

As shown in FIGS. 1 and 2, each traveling device 4 is configured to be vertically expandable and contractable by a pan tag clutch jack 15 that supports the top plate 2 and an operation handle 16 that operates the pantograph jack 15. There is.

The pantograph jack 15 has an upper end portion attached to the lower surface of the top plate 2, and a caster 17 provided at the lower portion. Advancing and retracting nuts 18, 18 are provided at the front and rear ends of the pantograph jack 15 in the middle in the vertical direction, respectively.

The operating handle 16 includes a male screw portion 19 and a handle portion 20. The male screw portion 19 is screwed with the advancing / retreating nuts 18, 18 of the pantograph jack 15, and has one end inserted into the shaft hole 7 of the bearing plate 6, while the other end has a handle of the leg portion 3. It projects outward from the insertion opening 11. The handle portion 20 is connected to the other end portion of the male screw portion 19 protruding outside the leg portion 3. When the operating handle 16 is rotated, the two advancing / retreating nuts 18, 18 move closer to each other or move away from each other, whereby the pantograph jack 15 expands and contracts in the vertical direction.

Here, a method of using the playing table of the first embodiment and a vibration isolation operation will be described.

When performing a piano performance by using the performance table 1, first, as shown in FIG. 1, the piano P is first fixed and installed on the performance table 1. In this state, the pan tag rough jack 15 is in the retracted position, and the casters 17 are retracted upward. Next, as shown in FIG. 2, in the storage place of the piano P, the four operation handles 16 are sequentially or simultaneously rotated to extend the pantograph jack 15 from the retracted position to the extended position. Lower 17 to position. By this operation, the casters 17 protrude below the lower end of the support base 10 of the leg portions 3 and the leg portions 3 float from the floor surface F, so that the traveling device 4 is in a state of supporting the performance table 1. In this state, the casters 17 allow the performance table 1 to be easily moved from the storage location to the performance hall. When the pedestal 1 is moved to a predetermined position in the performance hall, the operation handle 16 is rotated in the opposite direction to the direction described above, and the pantograph jack 15 is contracted from the extended position as shown in FIG. 17 is retracted upward to a predetermined retracted position. At this time, the supporting base 10 of the performance table 1 sits on the floor surface F of the performance venue, so that the legs 3 support the performance table 1.

When the piano P is played, the vibration of the performance sound is transmitted to the top plate 2 of the performance table 1 through the piano P itself. Further, this vibration tries to be transmitted from the top plate 2 to the leg body 8 and the supporting corner member 9, but since the first anti-vibration rubber 5 is attached between them, most of the vibration is absorbed by this. To be done. The vibration transmitted without being absorbed tries to reach the floor surface F via the leg body 8 and the support base 10. At this time, it is further absorbed by the second anti-vibration rubber 12 mounted so as to be sandwiched between the script body 8 and the support base 10. Therefore, a part of the performance sound of the piano P does not reach and resonate with the floor surface F of the performance hall, so that the performance sound of the piano P becomes clear.

On the other hand, the vibration of noise in the performance hall follows the transmission path opposite to the vibration of the performance sound described above, and most of the vibration is absorbed by the second anti-vibration rubber 12, and the rest of the vibration is generated. , Is absorbed by the first anti-vibration rubber 5.

When the performance ends, the pantograph jack 15 is extended from the retracted position to the extended position by taking the same procedure as when moving from the storage location to the performance hall, and the legs 3 are floated, and the performance is performed. Support the platform 1 (see FIG. 2). In this state, the performance table 1 can be stored by easily moving it from the performance venue to the storage location.

As described above, in the playing table 1 of the present embodiment, the vibration of the performance sound of the piano P is transmitted to the floor surface F via the playing table 1 by the first and second anti-vibration rubbers 5 and 12. It is possible to prevent the noise of the performance hall from being transmitted to the piano P via the floor surface F and the pedestal 1. In addition, by operating the operation handle 16 of the traveling device 4 and extending the pantograph jack 15 to the extended position, the traveling device 4 can support the playing table 1, and by retracting the pantograph jack 15 to the retracted position, Since the legs 3 can be seated on the floor surface F and can support the pedestal 1, the pedestal 1 can be easily moved to the performance hall and easily installed there. it can.

In the embodiment, the first and second anti-vibration rubbers are attached one by one, but a plurality of each may be provided. Further, in the embodiment, the four front and rear traveling devices are individually expanded and contracted using the operation handle, but the front two and the rear two are interlocked with each other, or all of the front and rear four are operated. It is also possible to operate the steering wheel in two places or in one place by linking. Further, although the traveling device is expanded and contracted by operating the steering wheel in the embodiment, it may be operated by operating the lever or by using a hydraulic mechanism. Also, although the grand piano is placed on the playing table, other musical instruments may be used. In addition, the detailed configuration can be changed as appropriate without departing from the spirit of the present invention.
