DETAILED DESCRIPTION OF THE INVENTION
(25) FIG. 1 shows a common, usually symmetrical reed 1 with the axis of symmetry or longitudinal axis 1f for reed and/or woodwind instruments. The front edge 1a is the vibrating edge of the vibration area 1b. In a clamping area 1c, which is thickened as compared to the vibration area 1b, the reed is clamped in a ligature, wherein its clamping devices according to the prior art exert a more or less large-surfaced press-on force onto the surface, which is curved in the transverse direction of the reed, of the clamping area 1c. Because the reed must vibrate in the vibration area 1b to generate sound, it only has a very small thickness, which leads to formation of the two lateral limiting surfaces 1d. In the clamping area 1c, the lateral limiting surfaces 1d extend in a taper with respect to each other such that the reed 1 becomes increasingly narrower toward the rear. Not shown in this figure is the completely flatly formed bottom 1e (cf. FIGS. 6a, 6b) of the reed, which forms the contact to the bearing surface of the mouthpiece 2 after assembly (cf. FIG. 2).
(26) FIG. 2 shows a standard design of an assembled mouthpiece 2 for playing music, as it is used with a large majority of woodwind instruments with a reed 1. The mouthpiece 2 has a connecting part 2a to the sound-producing chamber of the musical instrument, as well as a front edge 2b, into which the air is blown by the musician. In doing so, the front edge 2b is necessarily somewhat flush with the front edge of the reed 1a. The ligature 3 according to the prior art is mounted in the clamping area 1c of the reed. The bottom 1e of the reed rests against a usually axis-symmetrical bearing surface of the mouthpiece 2. The ligature 3 has a sheet 3a, which comprises the mouthpiece 2 together with the reed 1. The clamping force of the ligature 3 and thus the press-on force onto the reed 1 is exerted by two adjusting screws 3b. A special guide for the reed 1 for torsion-resistant and/or slide-resistant assembly, particularly also for a preassembled arrangement 7, 19 (cf. FIGS. 6a, 6b, 14) is not provided.
(27) According to FIG. 3, the reed 1 is first inserted into a preferably axis-symmetrically formed receiving block 4, which may be made of wood, as indicated in FIG. 3. The exclusively form-fitting ligature for the reed 1 in this exemplary embodiment is achieved in that, on one hand, the inner bearing surface 4a of the receiving block 4 is formed in a complementary manner with respect to the curved clamping area 1c of the reed 1. On the other hand, the limiting walls 4b and the inner side surfaces 4c formed on the inner sides of the walls are adapted to the conical curve of the lateral limiting surfaces 1d of the reed 1. The formation of the surfaces (4a, 4c) means that no point-by-point forces must act on the reed 1, which reduces the wear of the reed 1. The outer surface 4d of the receiving block 4 faced away from the reed may likewise be curved suitably. To facilitate assembly, a marking 4f formed, for example, with a notch or other recess is located at the front edge 4e of the receiving block 4. This marking 4f shows the musician that, at this point, the reed 1 must be inserted into the receiving block 4 with the front edge 1a ahead. In order to lock the receiving block 4 at the remaining components of the ligature 5 (cf. FIG. 4), there are two through-holes 4g arranged preferably symmetrically to a longitudinal and/or transverse axis in the inner bearing surface 4a of the receiving block 4.
(28) FIG. 4 shows the ligature and/or clamping devise formed according to the invention for the receiving block 5, wherein the receiving block 4 (cf. FIG. 3) can be combined with the most varied of ligatures 5 from the prior art. In a preferred embodiment, the clamping device 5 consists of a strap/belt 5a, for example made of leather or plastic, the ends of which are clamped together by means of an adjusting screw 5b with thread 5c and two guides 5d on the side of the mouthpiece 2 facing away from the receiving block 4 (cf. FIG. 8). According to FIG. 4, the strap/belt has two receiving holes 5e, which are placed congruently with the boreholes 4g of the receiving block 4 (cf. FIG. 3).
(29) FIG. 5 shows an alternative embodiment of the receiving block 4 with a meander spring 6, through which the reed 1 (cf. FIG. 1) can be pushed into the receiving block to different distances and, in doing so, still remain surrounded, in a form-fitting manner, by means of the limiting walls 4b of the receiving block 4 (cf. FIG. 3). This form of the spring is achieved in that, on the outer surface 4d of the receiving block, at least two grooves, notches, or other recesses 6a are milled over their entire length or also a part thereof in pairs, symmetrical and parallel to the axis of symmetry of the receiving block. To enhance the spring effect, a similar formation is undertaken at the inner side of the receiving block 4, for example at the cutting edge between the inner side surfaces 4c and the inner bearing surface 4a (cf. FIG. 3). An adaptation of the receiving block 4 to the dimensional deviations during the production of reeds 1 is possible by means of this embodiment of the invention.
(30) FIG. 6a shows an embodiment of a preassembled arrangement 7 for forming a form-fit and/or simultaneously a force-fitting coupling with the side surfaces 1d of the reed 1. Depicted is a receiving block 4 with the reed 1 inserted, wherein its flat bottom 1e is facing the observer. Two elastic spring bows 8, which are bent or curved one or more times, are affixed, with mechanical clamping at their ends, in the limiting walls 4b of the receiving block. Upon the insertion of a reed 1, the spring bows 8 bend in the shape of waves such that contact points 8a form between the spring bow 8 and the side surfaces 1d of the reed. Simultaneously, the inner side surfaces 4c, which are not visible here, rest against the side surfaces 1d of the reed in a form-fitting manner in the end areas of the receiving block 4. If a reed 1 is somewhat smaller due to production tolerances, it can still be affixed at the desired point in the receiving block 4 due to the force-fit of the spring bows 8.
(31) FIG. 6b shows an alternative embodiment to this of a preassembled arrangement 7 with a receiving block 4 for forming at least one force-fitting coupling with the side surfaces 1d of the reed 1. Depicted is likewise a receiving block 4 with the reed 1 inserted, wherein its flat bottom 1e is facing the observer. The limiting walls 4b themselves do not form any form-fit with the reed. Instead, two elastic bows 8, preferably mounted in the middle and/or so as to rotate, act upon the side surfaces 1d of the reed 1 while forming a mechanical compressive force at the preferably terminal contact points 8a. In this depiction, the elastic bows 8 are upstream of the limiting walls 4b with respect to the plane of symmetry and/or middle plane of the receiving block 4. Upon the insertion of a reed 1, the spring bows 8 bend with a decrease in the curvature. The reed 1 can then be inserted into the receiving block 4 until the side surfaces 1d of the reed, which are tapered with respect to one another, impact the central bearing points 9b, which are simultaneously formed as axes of rotation of the spring bows 8. In this end position, a form-fit is additionally achieved in addition to the force-fit.
(32) FIG. 7 shows the receiving block from FIG. 3 in a view of the outer sheath 4d, through the locking boreholes 4g of which two locking pins 9 are guided. The locking pins 9 are intended to connect or make connectable the receiving block 4 with a clamping device 5 in the holes 5e intended for this (see FIG. 4).
(33) FIG. 8 shows an arrangement of the clamping device 5 together with the receiving block 4, still before the insertion of the reed 1. The strap/belt 5a likewise has two receiving holes 5e (see FIG. 3), into which the locking pins 9 can be inserted. The boreholes in the strap/belt 5a have no thread. This makes a simple and tool-free replacement of the receiving block 4 possible in order to try out the receiving block with various materials for example.
(34) FIG. 9 shows an assembly according to the invention, based on the arrangement 10, of the reed 1 and of the mouthpiece 2 together with the spacers 12. In this embodiment, the spacers 12 fulfill the function of keeping any contact between the clamping device 5 and the mouthpiece 2 as small as possible and to suppress it completely in the ideal case. For this function, the spacers 12 are inserted between the strap/belt 5a and the mouthpiece 2 on both sides of the mouthpiece 2 (cannot be seen on the left). The spacers 12 themselves are formed such that the contact area 12a between them and the mouthpiece 2 is formed in the shape of dots and/or a line. Damping effects of the tensioning belt 5a on the sound quality and the response behavior are thereby suppressed. The spacers 12 can be made from any material, particularly from the same material as the mouthpiece 2 and/or the sound-producing chamber of the musical instrument. In order to keep the dimensions of the spacers 12 as small as possible, the receiving block 4 can be enlarged accordingly so that the side areas of the tensioning belt 5a are routed as far away from the mouthpiece 2 as possible.
(35) FIG. 10 shows a sectional view of a ligature, transverse to the longitudinal axis 2c in FIG. 11, which has a spacer device. With this spacer device, the contact points, lines, and/or surfaces 12a are formed as edges or protrusions of an upper part 17. The upper part 17 is connected to a simple fixing device 15, which affixes the reed 1, on the other side of the mouthpiece 2 via two rigid anchors 16. Any device known to musical experts, particularly a pressure plate, is suitable as the fixing device 15. A contact with the mouthpiece 2 is only established on the reed 1 itself and on the contact area 12a. To do this, the anchors 16 rest against the upper part 17, in a form-fitting manner, via a flat contact 16a. The reed 1 can no longer be twisted or slid after mounting by means of fastening means 16b, as they can be found also, for example, on the reed valves of the musical instrument. The clamping force is provided by the upper part 17. It consists of a bearing anchor 17a, to which the anchors 16 are connected. The clamping force itself is generated by a contact part 17b, which is connected to a knurled screw 18, as an adjusting screw, by means of a thread. The inner thread, which is intermeshed with the adjusting screw, is located in the bearing anchor 17a. If the knurled screw 18 is tightened, the contact part 17b moves onto the mouthpiece 2 and forms a line-shaped contact area 12a to the mouthpiece 2.
(36) FIG. 11 shows a side view of the embodiment from FIG. 10. Shown here is the tapered middle part of the mouthpiece 2, mounted around the ligature with a spacer device, in order to connect the reed 1 to the mouthpiece 2 in the reed's clamping area 1c. For the most form-fitting hold possible of the ligature on the mouthpiece 2, the fixing device 15 and the upper part 17 can be tilted with respect to each other, transverse to a longitudinal axis 2c of the mouthpiece.
(37) FIG. 12 shows a sectional view of an inventive embodiment transverse to the longitudinal axis 2c in FIG. 13, with two differences with respect to the embodiment from FIG. 10. The fixing device 15 has been replaced by a receiving block 4 according to the invention with all of the resulting, previously described advantages. Furthermore, the anchors 16 on the connection to the bearing anchors 17a do not form any flat bearing surface 16a. The lack of the flat contact surface 16a can be clearly understood in FIG. 13.
(38) FIG. 14 shows the preassembled arrangement 19 of a ligature according to the invention with a spacer device (16, 17, 18) and receiving block 4 (cf. preassembled arrangement 7 with spring bows 8, FIG. 6a). According to the method in accordance with the invention, the reed 1 is inserted to the rear into the desired position in the receiving block 4 such that the spring bows 8 make contact with the side surfaces 1d of the reed. The desired position is understood to be the position of the reed 1 relative to the receiving block 4. Due to the force-fit, which is simultaneously formed by the spring bows 8, the reed 1 can no longer change this position; in particular, it cannot fall out of the receiving block 4.
(39) FIG. 15 and FIG. 16 show perspective views of the assembly with the mouthpiece 2, based on the preassembled arrangement 19 according to FIG. 14. In this design, the contact between the preassembled arrangement 19 on the mouthpiece 2 is on the reed 1 itself and the contact surface 12a is limited on the contact part 17b. With the tightening of the knurled screw 18, the reed 1 is also affixed, ready to play music, in a twist-resistant and slide-resistant manner.
(40) FIG. 17 shows a sectional view of the assembly, undertaken along the dashed line through the mouthpiece 2, indicated in FIG. 9, wherein the spacers 12 and the tensioning belt 5a are hidden to simplify the representation. The influence of the receiving block 4 on the press-on force 14, which presses the reed 1 onto the mouthpiece 2, is shown here. If the force which the tensioning belt 5a exerts tangentially to its curve is broken down into a vertical and a horizontal component, only the vertical component is responsible for the press-on force of the reed 1 onto the mouthpiece 2. The more vertically the tensioning belt 5a is placed passed the reed 1, the larger the vertical component of the clamping force of the belt 5a. In the present embodiment, the receiving block 4 is designed so wide that the tensioning belt 5a can be placed completely vertically passed the mouthpiece 2. Thus, the clamping force 14 of the belt 5a is exclusively used for the twist-resistant and/or slide-resistant pressing of the reed 1 at the corresponding point, which reduces the risk of slipping when playing music. Through suitable dimensioning, also the spacer device, particularly the upper part 17 and anchor 16, can cause the press-on force 14 to be formed advantageously.
(41) FIG. 18 shows a clamp 21 for a fastening strap 20 (see FIG. 20), which is formed as one piece with an elongated strip 21a according to the exemplary embodiment. The clamp 21 and/or the strip 21a is preferably formed with spring-hardened rolled brass sheeting, elastically bendable plastic, or comparably suitable materials and is shown in the flatly placed state according to FIG. 18. Its elongated basic shape can be divided into three sections: A middle part 21h and two end sections 21f, 21g, which adjoin one another at one of the two opposites ends of the per se elongated middle part 21h. The latter is broadened as compared to the two in areas 21f, 21g and suitable for mounting fixing devices (general 15, cf. FIG. 10 and/or receiving block 4, cf. FIG. 13) for a reed 1 on the mouthpiece 2. The first end section 21f (to the left in FIG. 18) is equipped with a recess, which forms a slotted hole 21b to engage an engagement element 21c. The latter is designed in the form of a widening as compared to the longitudinal extension of the strip 21a on the available end of the second section 21g. In its middle section 21h, an elongated middle recess or punch-out is optionally formed, which particularly serves to reduce the weight. The opposite elongated edges, which terminate the middle recess on both sides, are equipped with suspension means 21d, implemented as punched or drilled attachment holes according to the exemplary embodiment, which are preferably arranged in the middle with respect to the longitudinal extension of the strip 21a. With respect to a longitudinal axis 21e of the middle part 21h, the two end sections 21f, 21g extend in tilted alignment, wherein an acute angle of, for example, 5-40°, 10° according to the drawing, is formed with the longitudinal axis 21e. Due to this quasi bent, buckled, or curved longitudinal curve, the strip 21a or the clamp 21 can adapt to the conical curve of a mouthpiece 2, when said strip is self-contained through bending, twisting around its own structural axis and upon insertion of the engagement element 21c into the slotted hole 21b. The twisting of the engagement element 21c around its structural axis is necessary due to the design with the aforementioned widening.
(42) FIG. 19 shows the clamp 21, which is flatly placed in FIG. 18, with the strip 21a being bent and self-contained in a circular shape. A mouthpiece 2 with an approximately circular cross-section can be completely enclosed with this strip 21a or clamp 21, which is approximately bent into a circular shape. The engagement element 21c implemented with the widening is inserted into the slotted hole 21b. To disconnect this coupling, the strip 21a must twisted around its longitudinal axis in an elastically reversible manner in order to align the engagement element 21c or its widening parallel or at least with such an oblique angle with respect to the slotted hole longitudinal sides such that the engagement element 21c, with its widening, can be pushed through the slotted hole 21b unencumbered. Depending on the position of the engagement element 21c within the slotted hole 21b relative to its longitudinal extension, the clamp 21 can encompass mouthpieces 2 of different sizes. Because there are no adjusting devices or other means acting on the clamp 21 for the adjustment thereof according to FIG. 19, the engagement element 21c assumes a position on the outermost end of the slotted hole 21b due to the spring-hardened elastically reversible material properties and the resulting reset force, wherein the circumference is the maximum which can be encompassed by the strip 21a.
(43) FIG. 20 shows a fastening strap 20, which has a clamp 21 in this case (cf. FIG. 19) and adaptation means for shifting and/or adjusting the engagement element 21c within the slotted hole 21b in order to encompass or surround or enclose mouthpieces 2 of different sizes. These means for adapting to differently sized mouthpieces 2 comprise, for example, an adjusting screw 22 and two nuts 23a, 23b engaging with the adjusting screw. One of the nuts 23a, 23b is connected to the first clamp end section 21f through welding, riveting, bonding, or another type of attachable or nondetachable joining process and preferably affixed to the available end, terminating at the slotted hole 21b, of the strip. The other respective nut 23a, 23b is connected to the second clamp end section 21g and preferably attached there to the widening strip 21a end formed on the engagement element 21c. The thread of the adjusting screw 22 is divided into two sequential sections in the longitudinal direction of the screw, a first thread section 22a and a second thread section 22b, wherein the directions of rotation of the two sections 22a, 22b rotate opposite one another, that is are oriented opposite one another. The direction of rotation of the first thread section 22a is formed, for example, as a right-hand thread, while the thread of the second thread section 22b is formed as a left-hand thread. The two thread sections 22a, 22b are separate from one another or distinct from one another, for example, by means of a radial thickening 22c of the shaft piece. The adjusting screw 22 can be operated or actuated via a handhold 22d.
(44) FIG. 21 illustrates, in a schematic view of the front of the fastening strap 20 and the adjusting screw 22 in its longitudinal extension, the operating principle with which the clamp 21 or the strip 21a can be adapted to the diameter of a mouthpiece 2. If the handhold 22d of the adjusting screw 22 is rotated clockwise, the two nuts 23a, 23b, which are engaged due to the opposite thread directions of the adjusting screw 22, obtain translational motions opposite one another such that the distance between the two nuts 23a, 23b enlarges. This goes hand in hand with an increasing clamping of the arrangement comprising the receiving block 4, bearing anchor 17a, and optionally other parts of the reed fixing device 15. The depicted arrows indicate this clamping process 24. Due to the enlargement of the distance between the two nuts 23a, 23b, the diameter which the strip 21a can encompass reduces. Thus, the clamping process 24 is initiated with which a reed 1 can be clamped to the mouthpiece 2 upon the mounting of a corresponding fixing device 15 (general 15, cf. FIG. 10 and/or receiving block 4, cf. FIG. 13) on the corresponding suspension means 21d (cf. FIGS. 19/20).
(45) FIG. 22 shows such a fixing mechanism, designed as a receiving block 4 (cf. FIG. 3) according to the invention, which is mounted on the suspension means 21d (cf. FIGS. 19/20) of the strip 21a with fastening means 25 or screws. A bearing anchor 17a is located opposite the receiving block 4. Due to the closing mechanism set specifically via the adjusting screw 22 and the engagement element 21c located in the slotted hole 21b, a contact part 17b (cf. FIG. 15) can be dispensed with. If the adjusting screw 22 is activated at the handhold 22d to initiate the clamping process 24 (cf. FIG. 21), the engagement element 21c of the sheet metal strip 21a moves, within the slotted hole 21b (cf. FIG. 19), to that the slotted hole end, which is remote from the available end of the strip 21a or closest to its middle part 21h, according to the representation in FIG. 22. Especially preferably, this arrangement may be implemented from the fastening strap 20 and receiving block 4 as a preassembled arrangement 19 (cf. FIG. 14), in which the reed 1 is affixed in the receiving block 4 (FIGS. 6a, 6b) by means of spring bows 8, for example made of metal or plastic, before initiation of the clamping process 24 (cf. FIG. 21). The mounting process onto the mouthpiece 2 is thereby significantly facilitated, because the musician has both hands available for sliding the fastening strap 20 onto the mouthpiece 2 and then only has to align the front edge 1a of the reed 1 at the front edge 2b of the mouthpiece 2. For the purposes of producing material equivalency, both the receiving block 4 and the bearing anchor 17a are produced from the same material as the mouthpiece 2. Many mouthpieces 2 are produced from ebonite, a natural rubber. Thus, it is appropriate to produce all components of the ligature, which form a contact surface with the mouthpiece 2 when mounted on the mouthpiece 2, from ebonite. All foreign materials, such as brass or iron, can thus be kept away from the mouthpiece 2.
