Description

Saxophone with improved octave button mechanism

The present invention relates to saxophones having the function of a modified octave button mechanism.

The saxophone is generally equipped with an octave button mechanism that allows it to alternately close or open two octave change ports.

The octave button mechanism conventionally includes a button platen or an octave button, and the rotary drive connection of the button platen or the octave button controls the closing or opening of one of the two octave changing holes. A plunger of the hinge rod of the system. One end of the rotating shaft that is rotatably attached to the saxophone body support is fastened to the button pressing plate and the other end is fastened to the plunger. A gear mechanism coupled between the plunger and a lever fastened to the lever transmits motion between the components opposite to the direction of rotation.

Thus, when the button presser is in an inactive position (typically a high equilibrium position in which it does not exert any force on the plunger), the swing arm system maintains two octaves to change the aperture closed. When the rotary button of the plunger is generated by the movement of the button press plate is transferred to a movable position The rocking arm system alternately opens one of the octave changing holes or the other causes the played notes to function. The device thus enables it to extend the scale of the sound of the instrument, in other words, the range of the instrument, which is accessible when a portion of the scale of the note is inactive at the position of the note, and the rest of the scale of the note when the button is in the active position Can be accessed. These parts of the scale of the note may correspond to an octave or more.

However, the intermediate moving member between the button presser and the hinge lever of this device features a certain blow that causes a delay between the actuation of the button presser and the actual change of the octave. This delay may be a problem for the musician, and the musician must anticipate this non-responsive situation and prepare in advance when playing. Even because the parts wear out for a long time, this blow may increase and the number of times needed to adjust the instrument often.

Therefore, there is a need to develop a saxophone that is reliable for the performance and more comfortable for the musician.

The present invention provides a saxophone, comprising a saxophone body and an octave button mechanism, the octave button mechanism comprising a button press plate and a hinge bar fastened to a rocker arm system, the button press plate being movable Between the first position and a second position, the button press plate is disposed on a fixed support fastened to the body and wherein the saxophone includes a lever fastened to the hinge rod and arranged to make the button The platen moves to direct direct contact between the button press plate and the lever to move the lever.

The first position of the button press plate may be an inactive position. Typically a balanced position and the second position can be an active position. As explained above, a first scale of the note of the instrument can be played when the button press is in the inactive position, and a second scale of the note can be played when the button press is in the active position.

By direct contact means direct contact between the button platen and the mutually facing surfaces of the lever without intermediate mechanical components and without a guiding or connecting mechanism between the button platen and the lever. The button presser thus directly applies a force to the lever, and the mutually contacting surfaces of the button presser and the lever slide over each other. The contact is direct at least when the button platen is moved from one of its positions to another, particularly from an inactive position to an active position. All moving contacts for the button press plate are advantageous.

In this way, the musician moves a button press plate mounted on the fixed part of the saxophone body, and the button press plate directly acts on the lever fastened to the hinge rod instead of indirectly via a plunger and a lever fastened to the hinge rod A movable shaft and gear type mechanical connection system between. The configuration according to the invention makes it possible to reduce the number of intermediate parts between the key platen and the hinge rod and in particular to reduce the number of intermediate moving parts. By reducing or even eliminating the delay time of the combined blow (this delay time exists between the action of the button press plate from the saxophone to the middle moving part of the hinge rod), this will allow the musician to play the saxophone more comfortably. The musician can therefore focus on her (his) performance without being bothered by the mechanical considerations of the instrument.

In particular, the lever can be located between the button press plate and the body of the saxophone. When the button presser moves, it faces the button presser of the body A surface is in direct contact with the lever.

The fixed support can be fixed to the body of the saxophone, for example welded or bonded.

Throughout the present invention, a reference to a component that is "fixed" or "fastened" to another component is understood to be a reference to a component that is not directly or indirectly fixed to the other component by an intermediate component.

The lever may be integrally formed with the hinge rod, such as welded to the hinge rod, molded with a workpiece and the hinge rod, or fixed to the hinge rod.

Further, in accordance with the present invention, the fixed support can form a thumb parking space. The button presser is integrally formed with a thumb parking place. Thus, the position of the button press plate relative to the parking of the thumb is less different than in the prior art. This is relatively important because a musician trying a new instrument may feel inconvenient because a few millimeters (more right or left, etc.) is higher than the position of the button presser that she is used to. In fact, in the prior art, because many components are used, the instruments may have considerable differences with each other, resulting in different positions of the button press plates between the instruments, which may be a problem for a musician. . Relative to the latter of the fixed part of the button platen, positioning the button platen at the thumb parking position allows the musician to find the same position of the button platen from one instrument to another. Moreover, the position of the saxophone's button presser according to the present invention can be the same as the position of the button presser of the conventional instrument without the need for an ergonomic correction to the musician, so the musician does not need to change the manner in which he or she plays. .

A thumb parking area contains a bearing surface on which a musician's thumb rests. This bearing surface can be planar, slightly convex or slightly concave. The bearing surface typically forms an angle of 90 with respect to a line perpendicular to the body of the saxophone.

In an advantageous and non-limiting manner, in the present invention, the bearing surface can be formed at an angle of ±10° with respect to the normal position described above. In other words, the bearing surface may form an angle from 80 to 89 or from 91 to 100 with respect to a line perpendicular to the body of the saxophone. Due to an improved comfort and improved ergonomics, this slight tilt allows the instrument to be adapted to each musician.

The movement of the button presser can be a rotation about a connecting shaft, a movement along a rail, and the like.

This movement can advantageously be a rotation, simpler to implement, advantageously around a surface substantially parallel to the body of the saxophone and/or parallel to the axis of the hinge rod.

In this case, the reverse of the rotation between the rotation of the key platen and the rotation of the hinge lever can be obtained simply by positioning the contact between the hinge plate and the rotating shaft of the key platen and the lever.

The connecting shaft of the button press plate can be placed between the center of the fixed support and the button press plate, more precisely between the center of the fixed support and the load surface of a button press plate. As a variant, the center of the fixed support can be placed between the button platen and the connecting shaft of the button platen. The shaft is located at a distance from the button press plate that is greater than the distance between the center of the fixed support and the button press plate. The greater the distance between the load surface of the button presser and the axis of the pressure applied by the musician's thumb, the smaller the amplitude of the angular displacement of the load surface is. The ergonomics and the comfort of the stroke during the activation of the button press plate are improved, and the displacement felt by the musician is close to a vertical translational displacement.

Moreover, the connecting shaft of the button press plate can be directly mounted on a component that forms a thumb parking place for the fixed support. In particular, the button press plate can be substantially in the same plane as the bearing surface of the thumb parking place, the button press plate is flush with the bearing surface of the thumb parking area and is actually continuous therewith, which can contribute to the thumb from the bearing surface to the button pressing plate. Move, and vice versa.

In a manner that does not limit the invention, particularly when the button presser is in an equilibrium position, the fixed support can advantageously be configured to permit adjustment of the position of the button presser relative to the body of the saxophone, such as an angular adjustment. This balance position corresponds to one of the positions of the button presser, and is generally an inactive position. The musician can therefore place the button presser in the position that best suits her (he). In particular, the fixed support may be such as by rotation about an axis substantially perpendicular to the surface of the body to which the support is secured and/or by winding a surface of the body to which the support is substantially parallel to the support. The rotation of the shaft allows for angular adjustment, such as a shaft of the button presser.

Adjusting the locking means can be provided when adjustment of the position of the button press is possible, these locking means being shaped to prevent any correction of the adjustment of the button press, particularly during a musician's use of the saxophone.

By directly arranging the button presser on the saxophone body rather than the moving shaft connected to the octave button mechanism, the present invention allows for some degree of freedom and better correctness in relation to the arrangement of the experience experienced by the musician. Sex, because the displacement of the position of the button platen is not a few millimeters. The button press plate is prevented from being carried on the lever fastened to the hinge rod and does not prevent it from performing its function. Moreover, the button press plate acts directly on the lever to allow good octave to change the response control of the system.

Advantageously and in a non-limiting manner, the components of the lever that directly contact the button press plate can be coated with a polymeric material. This allows for a reduction in friction between the button press plate and the lever, especially when these are made of metal or hard material, which improves the comfort of the blow (smooth play) and reduces noise.

Advantageously, the component of the lever that directly contacts the button press plate can form a roller and be rotatably mounted on the lever, particularly when the button presser activates the lever for rotation. The rotating shaft of the roller made of this polymeric material can be parallel to the axis of the hinge rod, and the lever is perpendicular to the latter.

When the button presser is moved between the first and second positions, the lever is also moved between a first position and a second position, one of which contacts the body of the saxophone. The amplitude displacement of the lever corresponds to the distance between these first and second positions. Advantageously and in an unrestricted manner, the lever includes means for adjusting its amplitude displacement. The means for adjusting may be a screw that is screwed into a screw hole in the direction of the body of the saxophone, the screw hole passing through a part of the lever that directly contacts the body of the saxophone, and the screw will be on the body of the saxophone The direction of the protrusion from the lever is more or less, depending on the extent to which the screw is locked.

Adjustment of the stroke of the lever may allow for an improvement in the opening of one of the holes that change the octave made in the body of the saxophone, while reducing the number of final blows resulting from the making or assembly of the different parts.

According to a particularly non-limiting embodiment, the button presser The fixed support can strongly include: a fixed base secured to the body of the saxophone; a removable support member for supporting the button press between the first and second positions; and means for moving The support member is fastened to the fixed base.

This makes it possible to easily change the key platen, which enables the production of a plurality of identical instruments having different shapes and/or key press plates made from different materials. Each musician can choose the button presser that best suits her (his) style of play or personalize it.

The fixed base can be fixed to the body of the saxophone, such as for bonding or welding.

The fixed base and the removable support member are advantageously adapted to permit movement of the removable support member about an axis of the surface substantially perpendicular to the surface of the saxophone body relative to the fixed base, the fixed support being secured to the surface . This adjustment of the angular movement allows the musician to adjust the position of the button press plate to improve the comfort of the blow.

When the saxophone is being used, a locking means can be provided to prevent any adjustable angular movement of the removable support member relative to the fixed base. The fastening means can advantageously be used as a locking means.

A particular arrangement that allows adjustment of the angular displacement can be obtained, for example, by separately creating a cylindrical member that fits a corresponding aperture on the fixed base or on the removable support member, the corresponding aperture being a through hole or relative to The removable support member or the fixed base is not fixed. The securing means may be a screw that is radially passed through the hole and urged against the cylindrical member. These fastening means also form a means for locking the angular movement of the button press plate.

The fixed base and the removable support member can be advantageously arranged such that the angular adjustment of the removable support member relative to the fixed base is limited. In particular, this angular movement can be tolerated within a predetermined range in which the button press plate maintains the contact lever and thus the octave control remains available for use within the predetermined range. This allows it to assist the musician in adjusting the angular position of the button press plate, and the musician is confident that the positioning button platen is properly positioned relative to the lever of the hinge rod without having to worry about the selected angle. The amplitude adjustment of the adjustment angle movement can be, for example, from 40° to 60°.

This adjustment angular movement can be limited by, for example, a groove and stop system created on the contact surfaces of the fixed base and the removable support member. This arrangement makes precise adjustment possible because such an arrangement allows any position between the two extreme positions imposed by the grooves.

For example, by creating a finger that protrudes perpendicularly from a surface of the fixed base or the removable support member and a plurality of separate holes for receiving the finger of the removable support member or the fixed base, The angular position of the separation can be provided equally between the removable support member and the fixed base. A similar result can be obtained by using a flat joint with a complementary hole or a serrated surface to secure the base and the removable support member.

In a first embodiment, the fixed base may advantageously include a screw hole having its shaft substantially perpendicular to the surface of the saxophone body, the fixed base being fixed to the surface, and the fastening means may be Advantageously, a screw member is included, the screw member comprising: a screw handle for engaging a screw hole of the fixing base; and a head for removing the screw member when the screw member is screwed into the fixing base The support member is locked to the fixed base and can be removed The support member includes a through hole that allows the shank to pass. This arrangement has the advantage of being simple to produce and containing a few constituent components. Moreover, the head of the screw can be locked without the use of a tool.

In particular, the head of the screw is used to form a thumb parking bearing surface. For this purpose, the visible surface of the screw head, in other words the surface opposite the threaded member, may be planar, slightly convex or slightly concave to form a thumb parking bearing surface.

For improved ergonomics, the button press plates can be placed on the same plane as the thumb parking surface on average.

To facilitate concealing the removable support member, the head of the screw member can completely cover the removable support member in a particular size.

The head of the screw member can be made of a variety of materials, such as mother-of-pearl, brass, bakelite, etc., which enable personalization of the fixed support.

In a second embodiment, the fixed base and the removable support member are advantageously coupled by a receptacle for receiving a complementary shaped projecting member, the receptacle and a body substantially perpendicular to the body of the saxophone. A projecting member of the surface extending from the shaft, the fixed base being fixed to the surface, the receptacle being fixed relative to the fixed base or the removable support member, and the projecting member being fixed relative to the other component. The component having the receptacle may include a through screw hole extending into the receptacle, the screw hole extending in a direction perpendicular to the axis of the receptacle, a screw screwing into the screw hole and abutting the protruding component to fix the base Fastened together with the removable support member.

The screw holes and the screws form a means of fastening the fixed base to the removable support member.

In this embodiment, the removable support member can, for example, form a thumb park bearing surface. The thumb park bearing surface can thus be flat, slightly convex or slightly concave. The removable support member can include an upper surface that defines a thumb park bearing surface that is generally perpendicular to the axis of the receptacle.

The receptacle and projecting member can be a cylindrical receptacle and a cylindrical projecting member that facilitates production.

In particular, the contact surface of the cylindrical receptacle and the cylindrical projecting member may be smooth, which allows for an accurate adjustment of the angular position of the removable support member relative to the fixed base. A groove and stop system of the type described above allows it to adjust the angular limit amplitude.

Additionally, these contact surfaces may include recesses that are parallel to the axis of the cylindrical receptacle, which enables a limited angular adjustment.

In another variant embodiment, the receptacle and the projecting member can have a polygonal cross section perpendicular to their axis, which also enables a limited angular adjustment.

Without considering the embodiment, the button press plate can advantageously be rotatably mounted to the removable support member, in particular about an axis substantially parallel to the surface of the saxophone body. The surface houses a fixed base for support.

In particular, when the fixed support forms a thumb parking place, the rotating shaft of the key press plate can be fastened between the bearing surface of the thumb parking area or the bearing surface at the thumb parking area and the body of the saxophone.

The saxophone can advantageously be used to hold the button presser in a predetermined position relative to the fixed support in at least one of the first or second position Set. This can be achieved by a fixed support of a suitable shape that limits its movement between the first and second positions of the button presser.

In particular, when the first support forms a thumb park, the button presser can be shaped to be flush with the load bearing surface of the thumb park or slightly inclined relative to the load bearing surface of the thumb park. The button presser is generally in the same plane as the load bearing surface and is generally continuous with it, which facilitates movement of the thumb from the load bearing surface to the key press plate, and vice versa.

The fixed support may, for example, comprise a spring securing means which, for example, may be shaped to hold the key press plate in a particular position relative to the fixed support. The spring retaining means can be shaped in particular to apply sufficient pressure to the button press plate to keep it pressed against the lever without regard to the position of the button press plate. Such an arrangement allows it to limit the operational noise of the button press and the transmission of the vibration of the instrument to the button press. The force applied by the spring means can be applied to the lever substantially parallel to the direction of its movement between the two positions of the button platen.

The spring fixing means may comprise a single spring (or even a plurality of springs), such as a leaf spring or a coil spring. The spring means may equally comprise more than one stop made of a polymeric material having the desired elasticity. .

The spring fixing means may include a coil spring received in a hole in the button pressing plate and pressed between the fixed bearing (for example, the head of the screw member) and the button pressing plate, the spring being selected to apply sufficient pressure to Press the button to keep it touching the lever of the hinge lever.

Generally, in a factory, by adjusting the position of the lever of the hinge lever by rotating the hinge lever, the tilt of the button presser relative to the fixed support can be Adjusted, and especially relative to the head of the screw. This adjustment can be achieved such that the assembly of the thumb park bearing surface and the button press plate remains planar in one of the first or second positions of the button presser. The position corresponds to an equilibrium state, for example, generally an inactive position.

Without considering the embodiment, the fixed support and the button press plate can be made of any material, which is usually cited in the manufacture of saxophone, namely steel, stainless steel, brass, precious metals (titanium, gold, silver, etc.), polymers. Materials, especially bakelite, mother-of-pearl and wood. When a metal based material is used, it can be surface treated, engraved, glazed or covered with a layer of precious metal.

As already explained, the button press plate can be integrally formed with a thumb parking place. In particular, for a fixed support as described above, a bearing surface of a component that is a removable support member or fastening means can form a bearing surface for the thumb parking.

Therefore, the object of the present invention may also be a saxophone thumb parking place, a button press plate is mounted on the thumb parking place, the button press plate is used to activate a hinge rod fastened to a rocker arm system and form an eight A component of the squeak button mechanism that is used to permit movement of the button presser between a first position and a second position. In particular, a saxophone having a parking place for the thumb having these features includes a hinge rod that is fastened to a rocker arm system that forms a component of an octave button mechanism that guides movement of the button platen By the direct contact between the button platen and the lever, the movement of the lever of the hinge rod is fastened. The thumb parking area can be fastened to the body of the saxophone by a fixed support, while the fixed support can have a fixed support as described above Various characteristics.

1 shows a partial perspective view of a saxophone 10 in accordance with the present invention, the saxophone 10 including a saxophone body 12 and an octave button mechanism 14.

The octave button mechanism 14 includes a button press plate 16 and a hinge bar 18 that is secured to a rocker arm system 20. The rocker arm system 20 is a conventional system for use with this type of musical instrument and is therefore not described in detail herein. Said.

The button presser 16 is movable between a first position or an inactive position (balanced position) and a second position or active position, and movement between the two positions mobilizes the rocker arm 20 to change the octave.

According to the present invention, the button presser 16 is mounted on a fixed support 30 that is fastened to the body 12 of the saxophone, and the hinge lever 18 moves the button presser 16 between its two positions to guide out The lever 19 fastened to the hinge lever 18 is moved by direct contact between the button presser 16 and a lever 19. For this purpose, in the present embodiment, the lever 19 is seated between the button presser 18 and the body 12 of the saxophone. As shown in Fig. 2, the lever 19, more precisely, its free end remote from the hinge lever 18 directly contacts the button presser 16. At this free end, the lever 19 further comprises a member 19a which can form a contact member with the body 12 of the saxophone. The implementation of a screw (not shown) in this screw hole 19b through this member 19a allows adjustment of the amplitude displacement of the lever 19. A similar screw 19'c is shown in further detail on Figures 5 and 6.

Although the movement of the key presser 16 can be in any form, such as a rotation about an articulation axis, a movement along a rail, or the like. To simplify production, this movement is advantageously a rotation about an articulation axis. In the illustrated example, the axis of rotation 17 of the button presser 16 is generally parallel to the surface of the body of the saxophone, and more particularly substantially parallel to the axis of the hinge rod 18. Further, a contact point between the key presser 16 and the lever 19 is seated between the hinge shaft 17 and the hinge lever 18, and the rotation energy is reversed during the pivoting of the key presser 16.

Fixed support 30 series can be used relative to saxophone The adjustment of the position of the button press plate 16 of the body 12, such as the angle adjustment, especially when the button press plate is in an equilibrium position, is here an inactive position. In particular, in this example, the fixed support 30 is adapted to permit adjustment of the fixed support 30 to the surface 13 by an angular adjustment about a pivot 34 that is substantially perpendicular to the surface of the body 12.

In the illustrated embodiment, the fixed support 30 of the button presser 16 includes a fixed base 31 secured to the body 12 of the saxophone, a button for supporting the button presser 16 between the first and second positions. The support member 32 is removed, as well as the means 33 for fastening the removable support member 32 to the fixed base 31. These components are shown in more detail in Figures 3 and 4.

The fixed base 31 and the removable support member 32 are adapted to permit angular movement relative to a removable support member 32 of the fixed base 31 about an axis generally perpendicular to the surface 13 of the body 12 of the saxophone, the fixed base The seat 31 is fixed to the surface 13. For this purpose, in the example shown, the fixed base 31 comprises a cylindrical member 310, a shafting shaft 34 of the cylindrical member 310, and the removable support member 32 has a cylindrical through hole 320 inside the through hole 320. The diameter corresponds to the outer diameter of the cylindrical member 310 so that it can be nested over the latter and pivoted about the shaft 34. The fixed base 31 and the removable support member 32 have respective planes 311 and 321 perpendicular to the shaft 34 which are in contact with each other when the removable support member 32 is attached to the fixed base 31.

In the example shown, the fixed base 31 further includes a curved surface 312 on the side opposite to the plane 311, the curved surface 312 being shaped to fit the surface 13 of the body 12 of the saxophone (see Fig. 4).

The cylindrical member 310 of the fixed base 31 includes a screw hole 313, the axis of the screw hole is the same as the axis 34.

The fixed base 31 can be welded or bonded to the body 12.

The removable support member 32 takes the form of a dish. The shaft shaft 34 of the disc passes through the shaft 34, and the one surface 321 of the disc contacts the surface 311 of the fixed base 31 and the opposite surface 322 of the surface 321 is parallel to the surface 321 . The cylindrical side 323 of the removable support member 32 includes a recess 324 that defines two projections 325, 326 whose mutually facing faces are parallel. These projections 325, 326 are pierced by respective apertures 327, 328 for receiving a cylindrical pin 35 having a shaft axis 17 that is perpendicular to the axis 34 of the removable support member 32.

The button presser 16 includes a support member 160 that is shaped to receive a recess 324 between the projections 325, 326. This support member 160 has a through hole (not shown) for the cylindrical pin 35 to pass therethrough.

The button presser 16 itself further includes a button presser member 161. The button presser member 161 is fastened to the support member 160, and the musician can apply pressure to the button presser member 160 to change the octave.

In the illustrated example, the means for securing the removable support member 32 to the fixed base 31 includes a screw member 33 that includes a shank 330 and a head 331 for mating a screw hole 313 of the base 31, and the head portion 331 is used to lock the removable support member 32 against the fixed base 31 when the screw member 33 is screwed into the fixed base 31, and the screw handle 330 is passed through the removable support Hole 320 in component 32.

For this purpose, the head 331 of the screw member 33 contains a flat Face 332, which is perpendicular to the shank 330 and cooperates with the plane 322 of the removable support member 32 when the fixed support 30 is installed.

The head 331 includes an opposite face 333 that is visible when the fixed support 30 is installed, and the opposite face 333 can be used to form a thumb park bearing surface. When the set of equipment is set up, the fixed support 30 thus forms a thumb parking place. In particular, as in the illustrated example, to conceal the removable support member 32, the head 331 has the same shape as the removable support member 32. When the fixed support 30 is used as a thumbrest parking place, its size will thus correspond to the size of a common thumb rest.

The angular movement of the removable support member 32 relative to the fixed base 31 is limited, particularly by a groove and stop system created at the contact surfaces of the fixed base and the removable support member. For this purpose, in the example shown, the plane 311 of the fixed base 31 includes a hole 314 in which the cylinder stop 315 is received and thus partially protrudes from the plane 311, the cylindrical stopper 315 It is perpendicular to the plane 311 and parallel to the axis 34. Its peer-to-peer removable support member 32 includes a circular arc-shaped (centered on shaft 34) groove 329 into which a portion of the cylindrical stopper 315 projecting from the fixed base 31 is received. 329.

The fixed support 30 may also include a spring retaining means in a position that does not take into account the button press plate, the means being shaped to apply sufficient pressure to the button presser 16 to maintain it against the lever 19. In the illustrated example, the spring retaining means includes a coil spring 36 that receives a receptacle 162 formed on one side of the support member 160 of the button press plate facing the screw member 33 for support The face 322 of the screw member 33 in the mounting position of the fixed support 30 is abutted.

The mounting and operation of the fixed support 30 and the key presser 16 will be described below.

The spring 36 is received in the receptacle 162 by the cylindrical pin 35, and the key presser 16 is mounted on the removable support member 32.

The mounting on the body of the saxophone is preferably in the following manner. The fixed base 31 is first fixed to the body 12 of the saxophone. The removable support member 32 on which the key presser 16 is mounted is mounted on the cylindrical member 310 of the fixed base 31, so that the planes 321 and 311 are in contact with each other, and the cylinder protruding from the fixed base 31 is stopped. The 315 is received in the groove 329 and the lever 19 of the hinge lever 18 is located between the button presser 16 and the body 12. The angular position of the button presser 16 can then be adjusted by rotation of the removable support member 32 about the shaft 34, which rotation is limited by the movement of the cylinder stop 315 in the groove 329. When the position is suitable for the musician, the screw member can be screwed into the fixed base 31 until the plane 332 contacts the plane 322 of the removable support member 32 and until the head 331 can no longer move. The spring 36 is then squeezed (in a direction parallel to the axis 34) between the support member 160 of the button press plate 16 and the plane 332 of the head 331, which enables it to hold the button press plate 16 against the lever 19. The rotation of the key platen 16 can be adjusted when the screw member 33 is partially screwed into the fixed base 31 but the surfaces 322, 332 are not in contact, which makes it possible to prevent the spring 36 from being lost.

The fixed support 31 is mounted in such a manner that the button press plate 16 is in a first position corresponding to a first scale of the note in which it abuts the lever 19 by the action of the spring 36. . This first position is generally an inactive equilibrium position of the button presser.

When the musician wishes to change the octave, she (the) applies pressure to the button presser in the direction of the saxophone body 12 until a second position of the button presser corresponding to a second scale of the note. This second position may be a position in which the lever 19 is adjacent to the body 12. Movement of the button presser 16 directs movement of the lever 19 and associated rotation of the hinge lever 18, which in turn enables the change in octave via the rocker arm system 20.

When the musician releases the button presser 16, the hinged lever 18 that is no longer restrained and rotated is rotated back to its original position by the spring means associated with the hinge lever 18 and/or the rocker arm system 20 is secured to the hinge lever 18 by The pressing force exerted by the lever 19 guides the key platen 16 back to its first position. Although no gear-type coupling mechanism is present between the button presser 16 and the lever 19, the presentation of the spring 36 that maintains permanent contact between the lever 19 and the button presser 16 allows it to limit the operational noise of the button presser 16.

In an embodiment not shown, the upper surface 322 of the removable support member 32 can be a solid surface and form a thumb park bearing surface. Additionally, the head 331 of the component 33 shown in FIG. 3 can be secured to the face 322 of the removable support member 32, which component 33 does not include any screws 330. The remainder of the removable support member 32 can be the same as those described for Figures 3 and 4.

The removable support member 32 can then be fastened to the fixed base 31 by screwing into a screw that is made through the screw holes of the removable support member 32. The screw hole extends from the outer surface of the removable support member 32 to its inner bore 320 in a direction perpendicular to the axis 34, and thus the screw The wire can come to the cylindrical member 310 that abuts the fixed base 31. Then, it is not necessary to generate a thread 313 inside the cylindrical member 310 of the fixed base 31.

In particular, the pin 35 to which the key platen 16 is attached may be mounted on the solid upper surface 322 of the removable support member 32 or below the head 331 of the member 33. The button presser members 161 and their supports 160 (more precisely, their upper surfaces) may be in the same plane, which is generally continuous with the thumb park bearing surface 333.

Figures 5 and 6 show another embodiment of a saxophone in accordance with the present invention. This embodiment differs from the previously described embodiment only in the shape of the lever and the position of the connecting shaft to the fixedly supported key platen. The same components are marked with the same symbol followed by "'.

These figures show that the lever 19' includes a member 19'd that directly contacts the button presser 16'. The lever member 19'd forms a roller and is attached to the lever 19' for rotation relative to a shaft 19'e.

In various embodiments, the levers 19 and 19' extend perpendicular to the hinge bar 18 or 18'. In the example of Figures 5 and 6, the axis 19'e of the roller 19'd is parallel to the hinge rod 18' and extends perpendicular to the lever 19'.

As in the previously described embodiment, the lever 19' includes a member 19'a that forms a body 12' that partially contacts the saxophone. The implementation of a screw 19'c in this part 19'a allows adjustment of the amplitude displacement of the lever 19'. The screw holes are similar to the screw holes shown in Fig. 2. In this example, the member 19'a is located between the free end of the lever 19' and the roller 19'd.

The rotating shaft 17' of the key presser 16' is compared to the previous embodiment The middle is located at a greater distance from the button press: in particular, Figure 5 shows that the center of the fixed support 30' is between the shaft 17' and the button presser 16'. The center of the fixed support 30' corresponds to the screw hole 313' of the fixed base 31'. The fixed support 30' itself also includes a removable support member 32' that surrounds the fixed base 31' rather than being received within the latter as in the example shown in FIG.

The invention is not limited to the embodiments described with respect to Figures 1 to 6, which may be combined with one another, in particular with regard to the position of the axis of rotation of the button press and the structure of the lever.
