Description

  The present invention relates to a woodwind instrument ligature in which a lead attached to a mouthpiece is fixed by a ring portion having a shape surrounding the outer periphery of the mouthpiece.

  For example, in a clarinet belonging to a single-lead woodwind instrument, the lead is attached to the mouthpiece using a member called a ligature made of a metal frame surrounding the outer periphery of the mouthpiece. The conventional ligature must be removed from the mouthpiece when replacing the lead, and it takes time and the attachment position of the lead needs to be adjusted each time. This work is nothing to say for a skilled player, but it takes time for an unfamiliar player, and the mounting position and the tightening strength are difficult to be fixed, which is a burden.

  An example of an application relating to ligature is, for example, Japanese Patent Application Laid-Open No. 2006-163382, which is an invention that effectively suppresses resonance of the ligature itself that could not be completely suppressed in a conventional metal ligature, Japanese Patent Application Laid-Open No. 2005-513578 has been made for a similar purpose. Japanese Patent Application Laid-Open No. 11-259064 is intended to prevent the metal of the ring from completely covering the mouthpiece, to make the tightening of the leads more average and to obtain a more natural sound. However, there is no technical proposal to solve the above problem in lead exchange.

  The present invention has been made paying attention to the above points, and its object is to enable a lead to be quickly and quickly replaced. Another object of the present invention is to allow the positions of leads to be accurately defined and exchanged. Another object of the present invention is to enable a player who is not accustomed to manage leads to a substantially constant state before and after replacement.

  In order to solve the above-mentioned problems, the present invention relates to a woodwind instrument ligature in which a lead attached to a mouthpiece is fixed by a ring portion having a shape surrounding the outer periphery of the mouthpiece. A ring portion having a tapered cylindrical shape is provided, and the separated portion includes a ring fixing portion that fastens the ring portion and fixes the ring at a fixed position of the mouthpiece, and further includes the ring portion. In order to set the lead fixing part to fix the lead in the attachment part corresponding to the pore part of the mouthpiece, and to place it as a lead fixing part at a predetermined position with minimal blur in the width direction when inserting the lead The side guide part formed inside the ring part with a width having a slight margin with respect to the lead width dimension, and the lead contacting the outer surface of the lead A lead holding member disposed inside the ring portion for pressing against the mouthpiece, and a stator attached by screwing to the ring portion for pressing and loosening the lead holding member against the lead. It is a measure to do.

  The woodwind instrument that is the subject of the present invention is a single-lead instrument such as a clarinet or saxophone due to the configuration of the reed disposed in the pores of the mouthpiece. This type of musical instrument lead has a tapered shape with a wide tip at the tip that touches the performer's lips and a narrow base at the base that is fixed to the mouthpiece. However, each specific instrument has a certain shape and size. Therefore, if the position of the ligature on the mouthpiece is constant, the position of the lead to be newly replaced is kept the same as the position of the lead before the replacement. The present invention is based on this relationship.

  The ring portion in the present invention has a substantially tapered cylindrical shape separated in part, and the separated portion has a ring fixing portion that fastens the ring portion and fixes the mouthpiece at a fixed position. It is necessary to do. The ring part is partly separated for attachment and detachment, and having a substantially tapered cylindrical shape is necessary for bringing the ring part into close contact with the outer shape of the mouthpiece having the same shape. It is. Note that the substantially tapered cylindrical shape may include only a frame that is literally surrounded by a cylindrical wall surface and that includes only a frame that conforms to the substantially tapered cylindrical shape.

  Furthermore, a lead fixing portion is set at an attachment portion of the ring portion corresponding to the pore portion of the mouthpiece. The pore portion of the mouthpiece is an opening portion that is substantially blocked by the lead, and the portion corresponding to the pore portion is a predetermined position where the lead is placed and fixed to close the opening portion, that is, the pore portion as described above. It means that. A configuration necessary for fixing the lead is provided at the above-mentioned portion of the ring portion having a substantially tapered cylindrical shape, and the lead fixing portion is a general term for the entire configuration.

  Specifically, the lead fixing part is placed inside the ring part with a width with a slight margin with respect to the lead width dimension in order to minimize the fluctuation in the width direction when inserting the lead and to place it at a predetermined position. To form. The left and right side surfaces of the lead and the lead fixing portion can contact each other, and the left and right side guide portions provided on the inner side of the ring portion for guiding the lead to a predetermined position and the outer surface of the lead are contacted with the mouse. A lead holding member arranged inside the ring part for pressing against the piece, and a stator attached to the ring part by screwing to hold the lead holding member against the lead and loosen it. Is done. Note that “contact is possible” refers to a situation where the lead is guided to a predetermined position with the left and right side surfaces of the lead and the lead fixing portion having a margin (gap) and the contact state is the limit. It doesn't mean. On the other hand, considering the case where the shake is extremely small, the width of the left and right side guides and the lead width are almost the same. It is possible that

  The left and right side guide portions are parts that guide the lead on the left and right sides, thereby guiding the position of the lead on the mouthpiece to a predetermined position. When the leads each having a certain form and size are exchanged, each lead is a portion that can take a position facing the left and right side surfaces under substantially the same conditions and can be contacted. Therefore, when the ring part is attached to a specific woodwind instrument, the distance between the left and right side guide parts is substantially constant. This side guide part can contact only the left and right side surfaces of the lead.

  The lead pressing member is a means for contacting the outer surface of the lead already positioned by the side guide portion and pressing the lead against the mouthpiece. Therefore, the form of contact can be freely determined as long as the lead can be pressed against the mouthpiece in a form that does not cause an acoustic problem. In one example, a shape having a substantially arc shape adapted to the shape of the outer surface of the lead, and having a plurality of ridges extending in the longitudinal direction of the lead and contacting the outer surface of the lead ( It can be said that this is an acoustically desirable form.

  In order to press and loosen the lead pressing member against the lead, a stator is attached to the ring portion by screwing. The stator has a male screw that is screwed into a female screw of the ring portion, and a portion for operating the male screw. If a single stator is provided at the center of the lead pressing member, the necessary minimum purpose can be achieved. However, in order to prevent the lead pressing member from shaking, a blur prevention mechanism can be provided. In addition, if two or more stators are attached in the longitudinal direction, it becomes an anti-shake mechanism. Further, the lead pressing member is disposed outside the side guide portion provided on the inner side of the ring portion with a receiving portion provided in the lead pressing member. A lead mounting space can be formed apart from the mounting portion corresponding to the pore portion (the invention according to claim 3), thereby facilitating insertion of the lead.

  Since the present invention is configured and operates as described above, the lead holding member is loosened by operating the stator in the lead fixing portion, the old lead is removed, the new lead is replaced, and the lead holding member is tightened. Therefore, the lead exchange time can be significantly shortened. That is, the ring portion is always fixed by the ring portion fixing portion, and only the lead needs to be replaced, so that the position of the lead can be accurately defined. Therefore, according to the present invention, even an unfamiliar player can manage the leads in a substantially constant state before and after replacement.

  Hereinafter, the ligature for woodwind instrument according to the present invention will be described in more detail with reference to the illustrated embodiment. Each figure shows an example in which the ligature 11 according to the present invention is applied to the woodwind instrument 10, and the lead 14 is arranged so as to cover the pore part 13 opened near the tip of the mouthpiece 12. The lead 14 has a taper shape that is wide at the tip of the player touching the lips and narrow at the base end fixed to the mouthpiece 12, has a predetermined size, and has a mouthpiece 12. It is fixed by the ligature 11 having a shape that surrounds the outer periphery.

  The ring portion 15 constituting the ligature 11 has a substantially tapered cylindrical shape that matches the outer shape of the mouthpiece 12 having a substantially tapered cylindrical shape, and a part of the substantially tapered cylindrical shape. In the separated portion, a ring fixing portion is provided as means for fastening the ring portion 15 and fixing the mouthpiece 12 in a fixed position. The illustrated ring fixing portion includes separation ends 16 and 17 provided so as to protrude outwardly at a portion separated on the side surface of the ring portion 15, and both separation ends 16 and 17 for closing the ring portion 15. And a ring fixing screw 19a having a screw portion 19 screwed into the screw hole 18 (see FIG. 2).

  In order to enable the lead 14 to be attached and detached in a state where the ring portion 15 is attached to the fixed position of the mouthpiece 12, a lead fixing portion is set at a portion on the ring corresponding to the pore portion 13 of the mouthpiece 12. The outward projecting portion 20 is formed there. The lead fixing portions are side guide portions 21 and 22 that guide the left and right side surfaces 14l and 14r of the lead 14 and fix them in place, and lead pressers that contact the outer surface of the lead 14 and press the lead 14 against the mouthpiece 12. In order to press and loosen the member 23 and the lead pressing member 23 against the lead 14, a stator 24 attached to the ring portion 15 by screwing is provided.

  The side guide portions 21 and 22 are formed inside the ring portion with a width having a slight margin with respect to the lead width dimension in order to minimize the fluctuation in the width direction when the lead is inserted and to be disposed at a predetermined position. Therefore, it is possible to contact the left and right side surfaces 14l and 14r of the lead 14. In addition, the side guide portions 21 and 22 have a necessary and sufficient length as a portion having a role of defining the position of the lead 14 on the mouthpiece. FIG. Further, the side guide portions 21 and 22 are provided inside the ring portion 15 so as to protrude toward the left and right side surfaces 14l and 14r of the lead 14. When the ring portion 15 is attached to the mouthpiece 12 of the specific woodwind instrument 10, the distance between the side guide portions 21 and 22 is set slightly larger than the lead width so that the lead 14 can be smoothly received. Has been.

  In the case of the ring portion 15 shown in the figure, an outwardly projecting portion 20 is formed outside the side guide portions 21 and 22, and a space outside the side guide portions 21 and 22 is led inside the portion. A holding member housing portion 25 is provided, and a lead holding member 23 is disposed there. The lead pressing member 23 corresponds to the pore portion of the mouthpiece 12 by arranging both sides in the space outside the side guide portions 21 and 22 provided inside the ring portion 15 and incorporating the elastic material 26 therein. It can be kept away from the attachment site (see FIG. 5), thereby freeing the space for attaching the lead 14.

  The lead holding member 23 is a substantially arc shape that conforms to the shape of the outer surface of the lead 14 as a means for contacting and pressing the mouthpiece 12 against the outer surface of the lead 14 already positioned by the side guide portions 21 and 22. And a plurality of ridges 27 that extend in the longitudinal direction of the lead 14 and contact the outer surface of the arc surface. .

  In order to hold down and loosen the lead holding member 23 against the lead 14, a stator 24 is screwed to the outwardly projecting portion 20 of the ring portion 15. Further, as a means for attaching the stator 24, a female screw 28 is formed on the outward projecting portion 20, and a male screw 29 that is screwed to the female screw 28 is provided on the stator 24. Further, the stator 24 is protected by a guard 30, and the guard mounting screw 31 protrudes downward and engages with the lead pressing member 23 and the notch 32 to prevent the lead pressing member 23 from blurring. Is forming.

  In order to use the thus configured woodwind instrument ligature 11 according to the present invention, the lead 14 and the ring portion 15 are attached to the mouthpiece 12 from the disassembled state shown in FIG. An object of the present invention is to facilitate the replacement of the lead 14, and it is assumed that the ring portion 15 is not removed. However, when attaching to the woodwind instrument 10 for the first time, it is important to determine the position of the lead 14 accurately. In such a case, the lead 14 and the ring portion 15 are attached simultaneously. It will be. In order to adjust the position of the ring portion 15, the ring fixing screw 19a is loosened and moved back and forth and tightened to determine the position.

  Once the attachment positions of the lead 14 and the ring portion 15 are determined, only the lead 14 needs to be replaced from the next time. When the stator 24 is loosened, the lead 14 can be displaced in the direction of the tip shown by a solid line in FIG. 7, and a new lead 14 can be inserted as shown by a broken line in FIG. That is, in order to attach the lead 14, the left and right side surfaces 14 l and 14 r have left and right side guide portions 21 and 22 of the ring portion 15 formed with a width having a slight margin with respect to the lead width dimension. While having a gap (margin) 33, it can be arranged at a predetermined position in a situation where contact is possible while minimizing fluctuation in the width direction. After the lead 14 is disposed at a predetermined position, the stator 24 may be tightened. 6 is ready for use, and thereafter, the lead 14 can be attached to the correct position only by repeatedly loosening and tightening the stator 24 each time it is replaced.
