Statement Piano frame

Technical field

The present invention relates to a frame used for an acoustic piano such as a grand piano. Background art

FIG. 9 shows a general frame of a conventional grand piano. The frame 100 is formed in the shape shown in the figure by metal structure, and has a large number of tuning pins 101 provided at a front end thereof and a large number of hitch bins 102 provided at a rear end thereof. Is provided. Between the tuning pin 101 and the hitch pin 102, a large number of strings 103 corresponding to each key (not shown) of the piano are stretched with a predetermined tension.

In the high-pitched portion of the piano, a force pod strobator (not shown) is formed on the back of the bones 100 a and 100 b of the frame 100, and the strings 103 are formed by the capoda strobers. And a long piece 105 provided on a soundboard (not shown), and are stretched between the tuning pin 101 and the hitch pin 102. This capoda strobe is used to determine the length of the string 103 (hereinafter referred to as “string length”) by pressing the string 103 and cooperating with the 驹 bin 106 of the long piece 105. And has a blade (not shown) that contacts the string 103. These blades are formed continuously by forming the frame 100 and then shaving the backs of the bones 100a and 100b of the frame 100 by hand or using a machine (router). Have been.

On the other hand, in the middle and low pitches of the piano, the string 103 is connected to the tuning pin 101 and the hitch pin 102 via the graph 104 and the long piece 105 or the short piece 107. It is stretched between. As shown in FIG. 10, the graph 104 is composed of a screw portion 104a and a head portion 104b, and the screw portion 104a is attached to the surface of the frame 100. By screwing into a threaded hole (not shown), ^ Attach.

The head 104b of the graph 104 is provided with one to three small holes 104c so that the strings 103 can pass through the holes 104c. I'm sorry. One graph 104 is provided for each key of the piano, and the interval, horizontality and string length between strings 103 in each key (in this case, graph 104 and The length of the chord between the piece pin 106 of the long piece 105 and the piece bin 108 of the short piece 107 is used to correctly regulate the length of the string. In this way, the length of the strings in the middle and low pitch side of the piano, even when two or three strings are used for one key, especially where these two or three strings are obliquely stringed, are aligned. This makes it possible to arrange the sounds neatly. In the conventional frame 100 having such a configuration, before stretching the string 103, (1) the work of making the blade of the power pod stroboscope, (2) the work of cutting a large number of screw holes, and ( 3) Three machining operations are performed: screwing the graph 104 into the screw holes.

In such a cutting operation of the frame 100, in the blade making operation of (1), the entire heavy frame 100 must be turned over to form the blade manually or by a machine (router). In the (2) threading operation, a large number of screw holes must be cut, and in the (3) screwing operation, a large number of graphs 104 must be screwed into the screw holes. Both operations require a great deal of labor and time, leading to an increase in manufacturing costs.

Also, when performing stringing work after the frame processing work of (1) to (3) above, in the case of a middle and low pitch part, the string 103 is inserted into the small hole 104b of the graph 104. It is necessary to pass the strings one by one, and in the case of the treble part, it is necessary to lay the string 103 under the capoda strobe bar one by one. This can lead to increased costs.

The frame 100 is housed and fixed in a support case (not shown). The support case includes a stack of wood, a back frame, and a plurality of columns (not shown). ) Are formed by assembling them together. More specifically, the soundboard is placed on a support case, a frame 100 is provided on the soundboard, and a side plate (not shown) is provided on the outer periphery of the loading. Is provided. 0 The frame 100 is fixed at its end to the mounting case in the support case together with the soundboard via wood screws 109, and is supported via frame bolts 110 at several places on the center side. It is fixed to the column of the case. Further, an adjustment bolt (not shown) of a column collector provided at the joint between the back frame and the column is strongly in contact with the jaw at the lower end of the frame 100.

On the other hand, in Grand Viano, in general, the tension of the string 103 extends from 17 to 20 tons as a whole and always acts on the frame 100. Occurs. The flexure of the frame 100 is applied to the support case supporting column and the back frame, etc., through the end of the frame 100, the frame bolt 110 and the adjusting bolt. Acts as a load. The supporting columns of the supporting case, the stacking and the back frame cooperate with each other to support the large bending load and the compressive load. Thus, in a grand piano, the large string tension is supported by the frame and the supporting case.

In such a conventional grand viano configuration, in order to support the large string 103 in cooperation with the frame 100, it is necessary to manufacture the support case with a considerably large strength. C Therefore, it is necessary to increase the cross-sectional areas of the support case, the columns that make up the support, the loading and unloading frames, and to assemble them firmly together. That ^ ¹ ^, M cost rises, assembling time and assembling cost? However, the cost increases. In addition, the support case made of wood is liable to be turned into ί; ί ^, and has a problem in durability.

To solve this problem, for example, it is conceivable to increase the rigidity of the frame 100 to reduce the load on the supporting case. However, if the rigidity of frame 100 is increased by increasing the thickness of t:, '::,';:,

Since 0 0 is heavy and occupies about 1 Z 3 of the original volume, the weight of the entire piano is greatly increased. In addition, if the rigidity of the frame 100 is to be increased by changing its shape, it is necessary to redesign the shape of the frame 100 and the design of the piano, resulting in a significant increase in cost. . Disclosure of the invention A first object of the present invention is to increase the rigidity of the frame without significantly increasing the manufacturing cost and weight of the piano, thereby reducing the string tension acting on the support case. The second is to provide a frame.

Further, a second object of the present invention is to provide a piano frame which can easily perform a frame processing operation and a stringing operation, thereby reducing manufacturing costs. .

In order to achieve the first object, according to a first aspect of the present invention, there is provided a frame body on which a string is stretched, and a tension of the string attached to the frame body and acting on the frame body. A supporting frame and a piano frame comprising: According to this piano frame, the rigidity of the frame can be increased by the reinforcing member attached to the frame body. Therefore, it is not necessary to change the thickness and the shape of the frame main body, so that the weight and manufacturing cost of the piano are not significantly increased. Also, most of the string tension can be supported by the frame, reducing the string tension acting on the support case. In other words, the role of the support case as a strength member such as a support column, a stacker, or a back frame The support case can be simplified or partially omitted, for example, by reducing the cross-sectional area of the columns or the number of columns.

Preferably, the reinforcement is attached to a portion of the frame body where string tension acts on the frame body as a bending compressive load,

According to this preferred aspect, since the bending compressive load acting on the frame main body is supported by the reinforcing material at the portion where the bending compressive load acts, the rigidity of the frame can be effectively increased.

More preferably, the reinforcing member includes: a plurality of brackets fixed to the frame main body; and a support fixed between the plurality of brackets.

According to this preferred aspect, since the bracket and the support are separate bodies, the degree of freedom in selecting the mounting location when mounting the reinforcing material on the frame body is increased, and the degree of freedom in the size and shape of the reinforcing material is increased. Therefore, it can be easily attached to existing frames. According to a second aspect of the present invention, there is provided a frame body on which a number of strings are stretched, and a plurality of frames fixed to the frame body and stretched. And a capod strobator which presses the strings to determine their length.

With this piano frame, the Kapodasutroba is constructed separately from the frame body, so that the Kapodasutroba blades can be cut without turning over the frame body. Also, it is possible to fix the capoda strobe bar after the strings have been stretched in advance, so that it is not necessary to pass the strings under the capo dust opening bar during the stringing work. As a result, frame processing and stringing can be performed easily and efficiently.

Preferably, the capoda strobe pushes a number of strings corresponding to the entire range of the piano so as to define their length.

According to this preferred embodiment, since the capodastrobar is provided so as to cover the entire range of the piano, an agraph conventionally provided in the middle and low-tone range becomes unnecessary. This eliminates the need for threading a large number of screw holes for attaching the gravure to the frame, and screwing the graft into these screw holes. It becomes unnecessary. Thereby, the frame processing operation and the stringing operation can be performed more easily and efficiently.

More preferably, the capoda strobe bar is composed of a plurality of capoda strollers separated from each other in the range of the sound range.

According to this preferred embodiment, when manufacturing the capoda strobe, a plurality of capoda strobes can be separately manufactured, and the blade can be separately formed for each of them, thereby facilitating the blade making operation of the force poda strobe.

"More preferably, the capoda strobe is provided with positioning means for laterally positioning a number of strings.

According to this preferred aspect, the spacing between the strings can be regulated by the positioning means without the a-graph, so that the spacing between the strings can be made to be exactly the same as in a piano having an a-graph.

More preferably, at a place where a plurality of strings are stretched for one key, A straight line connecting a plurality of pieces pins, each of which engages a plurality of strings, and a straight line connecting a plurality of portions of a capodastrobar, each of which a plurality of strings engages, are arranged in parallel with each other. .

According to this preferred embodiment, at a place where a plurality of strings are stretched on one key, the plurality of strings have the same length and become parallel to each other, so that even without the Just like a piano with a keyboard, it can make the sounds emitted from multiple strings corresponding to one key beautifully aligned.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a grand piano frame according to an embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1, the second grand piano G is provided with a stacking rod 3 inside the side plate 2 and an inner frame 4 between the front ends of the stacking poles 3. A plurality of columns 5 (only one is shown) are provided between the frames 4. Back At the front of the frame 4, a ramming 7 is attached via a middle frame 6. The loading 3, the back frame 4 and the strut 5 constitute a support case, on which a soundboard 8 is placed, and on which the frame 1 according to the present invention is mounted. ing. As shown in FIG. 3, the frame 1 is composed of a frame body 19 and a reinforcing member 20 attached to the lower surface of the frame body 19. The frame main body 19 is similar to a conventional frame, and is formed in a shape as shown in FIG. The rear edge of the curved surface of the frame body 19 is formed by a plurality of sets each including one screw 9 and two dowels 10 (for example, a support case together with the sound board 8 by seven sets of fixing tools). The front end of the frame body 19 is fixed to the bin plate 14 with six bolts 12 and the like. At the center position, it is fixed to the supporting column 5 of the supporting case by three frame bolts 11.

Also, a number of strings 17 are provided between a number of steel hitch bins 15 provided at the rear of the frame body 19 and a number of steel tuning pins 16 provided at the front end. It is stretched. The tension of the strings 17 has a magnitude of about 17 to 20 tons as a whole, and is constantly acting on the frame body 19. Due to such a balance, as shown in FIG. 1, a bending moat that acts on the frame main body 19 so as to bend upwardly or acts on the frame main body 19. The reinforcing members 20 are provided on the lower surfaces of the bones 19a at the right end of the frames 4 and 19 and the bones 19b at the left end thereof so as to extend in the direction of ^. FIG. 3 shows a 0 provided on the bone 19 a. The stiffener 20 is made up of two brackets 21 and 22 and a support 2 and. ', And these components 21, 22 and 23 are open and ^M † 籽, respectively. ,-. '. Η, a metal (for example, duralumin or titanium, etc.), etc., is formed in a predetermined ^ 认 (^, L-shaped or L-shaped cross section). Brackets Bok 2 1, the lower surface of讶1 9 a, the _c same which are fixed in 2 4 (fasteners such or bolt) screws, bracket 2 2 also, the lower surface of the front end portion of the frame body 1 9 The plurality of screws 25 are fixed. The support 23 is fixed between the brackets 21 and 22 by a plurality of screws 26 as shown by a chain line in the figure. By providing the reinforcing member 20 having high rigidity below the both side ends of the frame body 19 as shown in FIG. 2, the string body 17 acts to deflect the frame body 19 upward. The bending moment due to tension can be supported by the reinforcing member 20. In particular, the struts 23 of the strut 20 support the frame moment 19 so as not to bend while resisting this bending moment. As described above, the rigidity of the entire frame 1 including the frame main body 19 and the reinforcing member 20 is increased, so that most of the tension of the strings 17 can be supported by the frame 1.

As a result, the tension of the strings 17 acting on the support case becomes very small. It is possible to simplify or partially omit the support case by reducing the size of the support case or reducing the number of the columns 5. By simplifying or omitting the support case, the material cost and the assembly cost can be reduced, and the production cost of the vano can be reduced.

In addition, since the brackets 21 and 22 that constitute the reinforcing member 20 and the struts 23 and the light metal such as juralumin are used, the weight increase of the frame 1 accompanying the increase in rigidity is Very small compared to the case where the wall thickness is increased. In addition, since the brackets 21 and 22 of the reinforcing material 20 and the columns 23 and 23 are fixed to the frame body 19 with screws, the existing frame is used and only screw holes are provided. Reinforcement 20 can be attached. Therefore, the rigidity of the frame 1 can be increased at low cost without changing the shape of the frame and the accompanying design change of the 铸.

In the above embodiment, the reinforcing members 20 are provided on the bones 19 a and 19 b at both ends of the frame main body 19. c, 19 d, 19 e (see Fig. 2). In addition, the support posts 23 are fixed to the brackets 21 and 22 of the reinforcing material 20 with fasteners such as screws or bolts, but grooves of an appropriate shape are provided, and the brackets 21 and 22 are formed. The support 23 may be inserted between them, or the brackets 21 and 22 may be integrally formed with the frame body 19.

Further, in the above-described embodiment, the reinforcing member 20 is made of a light and highly rigid metal such as duralumin. 構成 It may be made of a readily available member, which can reduce costs. Further, the above embodiment may be applied to a strong piano, which is an example in which the present invention is applied to a grand piano.

Referring back to FIG. 2, the configuration of the grand piano G will be further described. The frame 1 further includes a capodastroba 31 attached to the frame body 19. The capodastrob 31 regulates the chord length of each chord 17 in cooperation with the short chords 32 and the long chords 33 attached to the upper surface of the soundboard 8.

The capoda strober 31 is made of metal, like the frame body 19, and is constituted by connecting the capoda strobe bars 40, 41 for the middle and low-frequency parts and the treble part to each other. From the to the right end, it extends over the entire range of the piano. The capodastrova 31 is fixed to the frame main body 19 by five screws 34 at the positions of the bone portions 19a to 19e. These screws 34 are inserted into holes (40b, 41b in Fig. 4; others are not shown) provided in the Cabodas transporter 31 and are provided in the bone parts 19a to l9e. Into the screw holes 3 5 (see Fig. 4). The two cappodastrobars 40, 41 are connected to each other by screws 34 at a position intersecting with the bone 19 d of the frame body 19.

As shown in FIG. 4, at the connecting portion of the two Kapodastrobars 40 and 41, as shown in FIG. 4, the projections 40a of the kapodastrobar 40 for the middle and low frequencies and the projections of the capodastrobar 41 for the treble portion. 41 a are mated so as to abut on the top and side surfaces of the bone 19 d. Further, the holes 40b, 41b are formed so as to penetrate the both protrusions 40a, 41a. Then, the screws 34 are inserted into these holes 40b and 41b, and screwed into the screw holes 35 of the bone portion 19d, so that the two capodastrover bars 40 and 41 are connected to each other. And is fixed to the frame body 19.

On the other hand, as shown in FIGS. 5 to 7, a band-shaped blade 43 is continuously formed on the lower surface of the Kapodastrova 31. As shown in FIG. 6, the string 17 wound around the tuning pin 16 is a string pillow 4 2 provided on the upper surface of the frame body 19 between the tuning pin 16 and the capodastro ', 31. While being pressed downward by the blade 43 of the capoda strober 1-31, it is stretched to the hitch pin 15 via the short pin 32 or the long piece 33. I have. In addition, as shown in FIGS. 5 and 7, the fourth to fourth strings 17 extending from the tuning pin 16 extend from the bottom of the Kapodastrova 40 with four positioning bins ( Positioning means) Hook bin 15 is hooked on 4 4, and once to the left in FIG. 5, and is stretched to hitch bin 15 via pin 3 2 a of short piece 32. When the string 17 is stretched straight from the hitch pin 15 to the tuning bin 16 and stretched, the strings 17 from the lowest tone to the fourth are the shape of the frame body 19 and the tuning pin. Because of the positional relationship between the hitch bins 15 and the hitch bins 15, the interval between them is likely to be narrow, so that this point is eliminated and a predetermined interval is maintained between the strings 17, 17. Each positioning bin 44 is made of metal, and a hole is made in advance at a predetermined position on the bottom surface of the caboda storage port 40, and the positioning bin 44 is driven into the hole, thereby obtaining a caboda storage port. Fixed to 0.

Furthermore, in the middle and treble side of the piano, where two to three strings 17 are used for one key, for example, as shown in Fig. 8, three strings 17 are long pieces, respectively. Engage with 6 pieces bins 3 3 a and 3 3 b of 3 3 and engage with blades 4 3 of Kapodastrova 31 at 3 places. In this case, a straight line L1 connecting the three piece bins 3 3a on the side of the capoda strober 4 and a straight line L2 connecting three engagement positions where the string 17 engages the blade 43 are mutually separated. It is configured to be parallel. With this configuration, in a place where two or three strings 17 are used for one key, the string lengths of the strings 17 can be made equal to each other, and the strings 17 can be made parallel to each other. Therefore, the sounds emitted from two or three strings 17 corresponding to one key can be neatly aligned, eliminating the need for conventional graphs.

Next, the processing and assembling work of the frame 1 including the kapodastrobar 31 and the stringing work of the string 17 will be described.

A. First, a screw hole for mounting the capoda strober 31 is formed at a predetermined position on the surface of the manufactured frame body 19.

B. Separately from above, make capog strobes 40 and 41 by fabrication, etc., and form blades 43 on the bottom surface. This blade-making work can be done manually or with a machine (router one):

C. Next, attach the tuning pin 16 to the pin plate 14 fixed to the frame body 19 and attach the hitch pin 15 to the frame body 19. further, Loosely tighten all strings 17 between tuning pin 16 and hitch pin 15.

D. The Kapodastrova 140 and Kapodastrova 141 are connected to each other, and the two connected Kapodastropar 31 are fixed to the frame body 19 via the screws 34.

E. After that, attach the finished sound board 8 to the support case, place the frame 1 on the support case, and hook the strings 17 on the piece pins 32a, 33a, 33b to adjust the tuning pin Turn 6 to tighten ½ 7 and adjust the tension. As described above, according to the frame 1 of the present embodiment, the frame body 19 and the Kapoda strober 31 are separate bodies, and the Kapoda strober 31 is divided into two parts, the force podastrova — 40 and 41. This makes it unnecessary to turn over the extremely heavy frame body 19 when making the Kapodastroba blades, which makes it easier to make blades. Also, after all the strings 17 are loosely stretched on the frame body 19, the force pedals 31 can be attached to the frame body 19, so unlike the conventional case, the strings 17 are attached to the capodas trova 3 There is no need to pass under 1 and stringing work can be performed efficiently.

In addition, since the a-graph is omitted, there is no need to perform thread cutting of a large number of screw holes to attach the a-graph, or to screw the a-graph into many screw holes. 1. The processing work becomes very simple. Further, for the same reason, it is not necessary to pass the string 17 through the hole of the graph, so that the stringing work can be performed more efficiently.

As described above, the force pox fc ′, 31 is separate from the frame body 19 and is divided into two parts. Work can be done efficiently, thus reducing manufacturing costs.

Note that the implementation ¾ above; information, the Kapodasu Toroha one 3 1, Kapodasutoroba - 4 0, 4 1 was a bisected ½ formation, also may _c a structure divided into three or more, Kapodasu As a fixing device for fixing the tray 31 to the frame body 19, a force using the screw 34 <, not limited to this, another suitable fixing device such as a bolt may be used. in the embodiment, the back surface of Kapodasu Bok mouth base one 3 1, as the positioning means, the four positioning pins 4 4 and the provided Chikaraku, the number is arbitrary ₌ more. Instead of the locating pins 4 4, a groove may be provided in the blade 43 of the capoda strobator 31 in a direction intersecting the extending direction of the blade 43, and the string 17 may be locked in this groove. No. Further, the shape of the blade 43 of the Kapodus Trouba 31 may be any shape as long as it can support the tension of the string 17. Industrial applicability
