Description

A kind of music score page turner

The utility model turns over the device of music score when being a kind of band performance, relate to the auxiliary equipment field of music.

Music score although the performance personnel are very familiar to the music score of Chinese operas, will be seen in order to insure still by band when playing.And present music easel can only be placed music score, has played after the spectrum of one page and must start page turning by the performance personnel.Because all musical instruments all will be played with hand, although every kind of musical instrument of large-scale band all is equipped with more than two,, is unlikely to make to play and pauses by wherein people's page turning, must finish because of people's page turning stops to play has certain influence to playing effect.Those soloists then must learn music score by heart, and this obviously brings certain difficulty to performance.

The page-turning apparatus for music book that the performance personnel did not stop and play when the purpose of this utility model was a kind of band performance of design.

We know, in numerous musical instruments, except piano, other musical instruments in performance all without pin.That is to say that most musical instruments pin when playing is a free, pin has action not influence performance.In view of this, this page turner adopts by foot-controlled scheme.This programme (as shown in Figure 2) is made of sticking head [2], turning arm [3], page turning mechanism and footstep mechanism, and turning arm [3] outer end is installed with sticking head [2], and its inner end connects page turning mechanism, and footstep mechanism is practiced [9] by rope and is connected with page turning mechanism.Page turner on music easel installation and duty as shown in Figure 1.The key of this page turner is a sticking head [2], and as Fig. 2, it is bowl-shape, and the root of bowl has holder and holder to go up on the porose plug that directly is set to turning arm [3] termination, and sticking head [2] is made by elastomeric material, and the inner surface of bowl scribbles adhesive sticker.For keeping viscosity for a long time, can be at sticking head [2] overcoat one cap [21], in that the time spent will not glued head [2] cover bag.Consider that adhesive sticker viscosity commonly used is too big, sticking music score is easy, is difficult for but decontrol then, makes troubles to page turning.So should select the not too big adhesive sticker of a kind of viscosity for use, as used the sort of adhesive sticker on the roll banding used of cleaning clothes.Modulate this glue and also be easier to, as long as in prescription, the composition of cohesive material has been reduced.Turning arm [3] (see figure 4) is that flat partially and the middle porose and termination of root has and curves the bar that right angle and car have the plug of groove.The page turning mechanism (see figure 4) practices [9] by support [5], torsion spring [6], wheel shaft [7], rope and clip [4] is formed.In the middle of support [5] two vertical plate of cross section one-tenth " п " type the hole of passing for wheel shaft [7] is arranged, and beat in the periphery of left riser upper shaft hole a plurality of the connection with clip [4] and the screws of fastening clip [4], and right riser becomes removable mounting at the first half of axis hole, by making a call to two holes above the riser, Lower Half correspondence position at the riser axis hole has screwed hole, with screw with axis hole two removable mountings up and down, design so pure broken be to be that wheel shaft [7] is installed is convenient.Nearly clip [4] root (left end) car of wheel shaft [7] has wiring to practice the wheel of [9], and there is the bar around torsion spring [6] at the middle part, and end (right-hand member) has the opening fork, and stick porose, the right-hand member of wheel shaft [7] is thinner than middle part diameter, wheel shaft [7] just in time is stuck between two risers locatees, and is unlikely dislocation.It is little, laborsaving to rub during certainly for page turning, also can add bearing between wheel shaft [7] and axis hole, and the root of turning arm [3] inserts in the opening fork, by screw [8] hinge.One end of torsion spring [6] inserts in the hole on the wheel shaft [7], and the other end inserts in the hole on the support [5], and rope is practiced [9] and gone up the knotting of other end, back around wheel and be stuck in wheel along in the last groove.The spiral shell of torsion spring [6] to rope practice [9] around to opposite.The wheel shaft here [7] is mounted in the peristome of clip [4], promptly the axis of wheel shaft [7] not with the axes intersect of hack lever [11], but be tangential on outside hack lever [11] periphery.The left side that the opening part of clip during installation [4] is positioned at hack lever [11] makes wheel shaft [7] and music score face quadrature.Turning arm [3] just in time makes sticking head [2] press music score bottom right edge place at ordinary times so, and when page turning, turning arm [3] turns over 180 °, and obviously its sticking head [2] has just exceeded the left edge of music score.We are needed just for this point.Because have only page turning sticking head [2] excess edge to the left just can make sticking head [2] break away from and the music score page is balanced, and when return, this page or leaf can not turned back again with the stickup of music score.Footstep mechanism practices [9] by lower catch hoop [4], pedal [10], rope and wire clips [13] is formed.Pedal [10] (see figure 5) is a metallic plate, one end has hinge lug with holes, nearly hinge lug place, middle part has wire rope handling to practice the ring of [9], the trip bolt [4] of clip [4] passes pedal [10] hinge earhole pedal [10] is positioned at hack lever [11] bottom, wire clips [13] (see figure 6) has a straight hole arranged side by side and a curved hole on it, its diameter is more bigger than rope white silk [9], rope is practiced the end knotting of [9] and is from top to bottom passed from the straight hole on the wire clips [13], down pass the ring on the pedal [10], after up passing the curved hole on the wire clips [13] again, directly on the wheel of wheel shaft [7].Wire clips wherein [13] is exactly the card that bungee commonly used is practiced usefulness.Because in use different user needs different height, be to be seated as violin etc., Double bass is then being stood, and just needs to regulate the height of music stand.When regulating, to transfer hack lever [11], transfer rope to practice [9] again.Hack lever [11] is preceding must transfer slack rope card [13] earlier to this kind wire clips [13] transferring, behind the hack lever to be mixed up [11], at last again with wire clips [13] location, still some inconvenience.For more convenient, wire clips can be designed to structure as shown in Figure 7: on metal derby, make a call to two straight holes side by side, the horizontal from outside to inside groove of opening is made an appointment with half place to the hole in centre, a hole, smaller metal clamp [14] (see figure 9) of one thickness is installed in the groove, one side is porose in clamp [14] inner end, by from top to down screw [18] on the metal derby with its hinge, the nearly hinge place of clamp [14] transverse side posts a rubber [22], opposite side has wedge shape grab [15] to be exposed at outside the whole metal derby in clamp [14] inner end, match with the stop hook [16] of this side, and stop hook [16] (see figure 8) is the rectangular flat board that curves the right angle with grab [15] contact position, and the two sections gardens pipe that is connected of the both sides in the middle, folder one torsion spring [17] back is passed and hinge together with the hole on two ears that are connected on the metal derby in the lump by a pin [23] between two pipes.This structure is actually a kind of curved pore structure of variation.Promptly when grab [15] is pushed back, because the lozenges of its hook promotes the bent angle of stop hook [16] stop hook is lifted, the hook portion of grab [15] advances, and blocks grab [15] by bent angle, clamp [14] is just pushed down rope white silk [9] and can not be slided in the hole of wire rope handling white silk [9], make whole rope practice [9] stretching; When the bent angle portion of stop hook [16] is lifted at the rear portion of hand stop hook [16], because clamp [14] hinge root has the effect of rubber, baffle plate [14] drives the card that colludes that grab [15] just breaks away from stop hook [16], and clamp [14] is just practiced [9] to restricting and lost extruding force, and rope is practiced [9] and just can be adjusted up and down.Though this structure is complicated, an available hand operated, the height of the adjustable hack lever of another hand [11] can be finished the work of heightening quickly simultaneously.

The course of work of this page turner is: if dispose page turner again on existing music easel, so earlier that front band [4] opening part is fastening to front-left, the curved angle of pitch adjustment turning arm [3] according to the spectrum face, make sticking head [2] be pressed in the limit, bottom right of music paper, at this moment the torsion spring [6] on the wheel shaft [7] is in reset condition, and lower catch hoop [4] is installed again, and make rope practice [9] fixing back on the wheel from after rotate the 1-2 circle forward, adjust wire clips [13], press the height of hack lever [11], make rope practice [9] stretching.When the needs page turning, with pin pedal [10] down, rope is practiced [9] toward drop-down, and wheel shaft [7] (counterclockwise) left rotates, and driven rotary arm [3] rotates from right to left, together turns over left because the effect of sticking [2] just drives one page paper.And the root of turning arm [3] is outside the music score face, and become a fixed angle with wheel shaft [7], so during turning arm [3] rotation, sticking head [2] forms a parabolic motion track with the spectrum face aloft, promptly sticking head [2] except that on both sides with the music score face touches mutually, do not wipe mutually in the rotary course with the music score face.When turning arm [3] turns over 180 °, because of wheel shaft [7] installation site take back (also wanting many) at the radius of music score paper center line the first from left hack lever [11], make sticking head [2] adhesion music paper also toward exceeding the wide direction motion of left side paper, so sticking head [2] just can be thrown off the stickup to paper, at this moment decontrol pedal [10], because of wheel shaft [7] in the last process rotates torsion spring [6] is tightened simultaneously, in case decontrol, torsion spring [6] just tries hard to restore to the original state, counter-rotating is 180 ° clockwise, so driven rotary arm [3] reposition again is in (static) state of awaiting orders again.

The utility model not only can only turn over one page (confirming through test) reliably owing to adopted the mode of sticking page page turning at every turn, and structurally also very simple, is a kind of simple plant equipment.Therefore, service life, the person was reliable, and maintenance is few, installs easily, and is easy to use, and can easily solve pauses plays the problem of page turning.It is applicable to all musical instruments except that piano.
