Description

The invention relates to a conservatory type oboe, of the removable type in at least one low body and a high body. According to the invention, the latter represents more than half of the complete instrument, and is preferably interrupted between the hole of Mi and that of Mib. The pavilion only begins after the last hole and the last key.

Optionally, for a key comprising a ground hole tray that closes the round of Sol # and actuates the large rocker to open the holes of Bb and C medium, the floor plate causes a rear bracket, preferably linked to the square of large rocker, and which entails a bracket fixed to a heel of Sol #.

Optionally, alternately or in combination, the key includes a C tray between the Sol hole tray and Sol # hole. This plateau of Do causes the big rocker and the round of Sol #, instead of the plateau of Sol. It is driven by it but can be operated by the user alone.

State of the art

The oboe is a wind instrument, from the family of "woods", formed by an elongated tube whose inner pipe, the "bore", has a conical shape. The sound is produced at the end of smaller diameter, or "high", by a user who blows into a double reed inserted into the opening of the duct, and generally formed by two reed plates assembled together. The sound propagates in the form of a column of air vibrating inside the tube, to its opposite end, or "low" end, through which the bore opens out by a part usually flared called flag. The tube is pierced with a plurality of lateral holes, distributed along its length, whose open or closed state adjusts the height of the sound produced by the instrument.

Within the woods family, the oboe group is now a clearly defined family, which mainly comprises the following varieties: Oboe (in C), Oboe of Love (in La), English Horn (in F), Baritone Oboe (in C grave), Heckelphone, Oboe Musette or Piccolo (in Eb or in Fa). Traditionally professional oboes are made in Grenadilla, also called Mozambique ebony (Dalbergia Melanoxylon). However, other materials are also used for example for study instruments but not exclusively, for example composite materials, polymers, metals.

In the modern oboe family, the holes are not plugged directly by the musician's fingers. The closure of the hole is performed by a buffer carried by a rigid round mounted on a pivoting arm on an axis. Some holes are open at rest, and others are closed at rest.

The displacement of this round is obtained in various ways, for example by pressing the finger on a plate covering the round, or by pressing on the opposite end of the arm, directly for via one or more rods or hinges, by manipulation one or more other trays, or spatulas or levers. All of these elements contributing to producing different hole opening configurations form a key mechanism forming a "keying".

Currently, all instruments of the modern oboe family, at least in the field of Western "classical" music, have a similar or identical keying all models with some details or options: the most common configuration is based on the system "Triebert" developed from the nineteenth century, and now frozen under the name of "Conservatoire".

FIGURE 1 and FIGURE 2 illustrate a conservatory type O oboe of a known type.

In a central part of the instrument, the hole of Sol is closed by manually pressing on a plateau here called plateau of Sol. if the previous holes are closed and the next hole (F #) is open, the instrument will play the sound F #. In the Conservatory mechanism, the actuation of this floor plate causes the actuation of several other mechanisms on the side of the upper end of the instrument. In particular, it produces a closing support of the hole of Sol # by a generally oblique branch which starts from the longitudinal hinge of Sol and comes to press directly on the round of Sol #. In addition, it simultaneously produces the opening of the holes of Do and Sib, via a longitudinal lever, called "large rocker" (GB), which switches to rotate the hinges which are also longitudinal.

In the prior art, for example as illustrated in FIG. 2, the instrument according to the prior art can be easily disassembled by the user, without technical knowledge or professional tools, generally to be stored in a less bulky case. As shown in the figure, on most instruments, this disassembly is done by separating the following three elements.

A top body includes the piperelle upward and extends downward past the Sol # hole. He carries the big rocker and the mechanisms of the key of Sol # and the rolled key. The upper body has at its lower end a stud adapted to fit into a socket of a lower body.

This lower body begins with the hole of Sol and its hinge, and carries an end shell that supports the crow's feet. The floor hinge carries a drive-forward correspondence and the "snake" forward, which respectively actuate the large rocker and press the round of the buffer covering the floor # once the instrument is reassembled . At its low end, the lower body extends to the grave hole of Do. It has at its lower end a pin designed to fit into a socket of an element called horn, which includes the holes of Si and Bb resonance and their mechanism. Once the instrument is reassembled, this mechanism can be actuated from the bottom body by cooperation between their respective correspondences.

It has also been proposed by document FR 2 867 891 to make a different cut, in which the upper body is much shorter, and is interrupted between the note holes and the octave holes, and in particular above two trill holes. The body of the proposed bottom is enlarged upwards as much, and interrupts down unchanged as in FIGURE 2. This solution makes it possible to limit the length and the cost of the high part, which is often the part the most fragile to use.

This solution does not solve all the disadvantages, however, and can provide others.

An object of the invention is thus to overcome the limitations or disadvantages of the prior art, in particular as detailed above.

Presentation of the invention

According to a first aspect, the invention thus proposes a musical instrument of the oboe family, or a keying mechanism for such an instrument, in which the instrument comprises an elongate body pierced with a plurality of note holes distributed among more acute to the most serious between respectively a high end and a low end, and wherein said body carries a keying mechanism arranged according to the system called "Conservatory" to allow a user to control the closure of all or part of said holes of notes. The invention applies to such an instrument, wherein the body comprises at least two parts arranged to be disassembled and assembled together routinely by a user, for example a musician and in any case not necessarily an instrument technician of music, and hand tools easily transportable, including each transport between two places of use.

According to this aspect, these parts comprise: a bottom body, whose lower end forms the roof or is arranged to receive a portion forming said roof, and a body of the upper bearing at its upper end a piperella arranged to receive a reed, which upper body has a length equal to at least half of the total length of the body of the instrument.

Preferably, the body of the top has a length of between 0.5 and 0.65 times the total length of the body of the instrument.

According to an advantageous feature, the upper body and the lower body are assembled and disassembled in a transverse plane which intersects their outer surface between the hole of Fa and the hole of Reb or C #.

Specifically, the top body and the bottom body are preferably assembled and disassembled in a transverse plane which intersects their outer surface between the Mi hole and the Mib or Re # hole.

Preferably, the keying mechanism is distributed as follows between the body of the top and the bottom: the body of the top carries the fasteners (preferably in their entirety) of the axes or hinges of the plate of the hole of Mi and Fa fork; and the lower body carries the fixings of the axis supporting the round of the resonance hole Fa, as well as the fixings of the axes supporting the lever Eb, the lever of Do #, and the key of Do serious.

More precisely, this distribution has, moreover, and preferably, the following characteristics: the body of the top furthermore carries the fastenings of the axis of the small rocker which controls the round of the resonance hole Fa; and the upper end of the lower body is surrounded by a metal ferrule which carries on the one hand the fasteners of the axis supporting the key Gillet and on the other hand the attachment of the end of the axis or hinge of the Do not serious key.

According to another advantageous feature, which may or may not be combined with the previous one, the upper body and the lower body together carry all the elements of the keying mechanism; and the lower end of the bottom body is arranged to removably receive by the user a part forming the flag and devoid of any mechanism connected to the mechanism carried by the body of the bottom.

It should be noted that this peculiarity, of a shortened and non-mechanically supported roof, can also be implemented independently of the first aspect, on an instrument whose upper body and the lower body are separated between the hole of Sol and the hole of Sol #. The body of the bottom is then slightly elongated.

Thus, in an instrument according to the present invention, the body of the top is longer and thus allows to bring the two hands of the musician on the same piece, providing for example a better stability and improved strength. In addition, on all of this body from above, the integrity and continuity of the bore are improved, and thus the quality and stability of the air column set in vibration. As it is understood, this new division postpones the discontinuity between the upper and lower bodies lower, where it turns out that it has less influence on the quality of the sound. The homogeneity of the instrument is thus significantly improved.

In addition, this new cutting of the instrument solves mechanical problems within keys, which are recurrent on the oboe. These problems relate for example to the "snake" located at the usual location of the junction of the bodies of the top and bottom of the traditional instruments. Indeed, this snake has a tendency to disintegrate very easily, even to be damaged, causing a malfunction of the instrument or requiring makeshift or even more complex repairs.

This cutting according to this aspect of the invention may have certain disadvantages. For example, if slits occur in the upper body that is most sensitive to it, the part to be replaced will be longer and more expensive. In addition, it represents the largest part of the instrument, and has a longer length than that of FIGURE 2, which implies a larger footprint of the disassembled instrument.

However, such cutting also has advantages. The pavilion is simpler and less expensive to manufacture. Since it carries no mechanism, it is no longer necessary to make and adjust matches between the flag and the body of the bottom. The hull of the flag is also optional, because less necessary since it has no mechanism to support. It also becomes easier and less expensive to use several interchangeable flags, for example to use a flag having a different internal profile which allows to change the sound of the instrument.

In addition, the upper part of the instrument can thus be made in one piece over a greater length. The cost and complexity of manufacture may be higher, but it has the advantage of greater continuity and regularity of the bore. But it is in this high part that this parameter is the most important. The invention thus allows a better quality, reliability and / or repeatability of the sound produced.

In addition, the body of the upper form and the same piece that carries both the big rocker, the hole of Sol # but also the hinge and the plateau of Sol. The problems of fragility, control and reliability of these mechanisms, whether or not they include the characteristics of the first and second aspects, are greatly diminished. The space available for implanting these mechanisms is also greater because of the absence of the cutting plane, the ferrule, and the fragile region created by such a cut.

In addition, since the cut is made lower than in the prior art of FIGURE 2, the tube has a larger diameter at this location, about 1 to 1.5 mm in diameter. The tenon and the socket which are cut in the thickness of the wall of the tube, and fit together to maintain the assembled parts, thus have a greater diameter than in the prior art. This gives them greater mechanical strength. This represents an advantage, especially in the case of using polymeric or composite materials for which the tenon of the upper body may represent a mechanical fragility and leading to a risk of breakage. Soil mechanism # The invention further provides a second aspect, possibly in accordance with the first aspect but which can also be implemented independently.

FIG. 1 and FIG. 2 illustrate an example of a "conservatory" type mechanism, as is currently provided for on the instruments of the prior art, that they be divided into two bodies of substantially equal lengths, but also cut differently. as that of document FR 2 867 891.

This mechanism allows for many possibilities, and has been exploited by all classical musicians for many decades. It is however quite complex to handle, and sometimes presents particular difficulties, for example to play certain sounds in a specific or particularly fast musical context. It remains interesting to improve its ease and / or reliability of use, the possibilities it offers in terms of possible fingerings and sound quality it allows, but also ergonomics and robustness, reliability and stability.

According to this second aspect, the invention proposes such an instrument or a mechanism for such an instrument, wherein said keying comprises: a floor plate pivoting about an axis of ground and operable to lower a ground buffer, a side of said front axis so that it closes the hole of Sol, which is open in the rest position of said ground buffer; a round of Sol # bearing a Sol # buffer and pivoting around a Sol # axis that is parallel to the Sol axis, so as to close the Sol # hole in the low position and leave it open in high position ; and a rod, said large rocker, which pivots on an axis perpendicular to the axis of Sol and is disposed on the side of the upper end relative to the hole of Sol; which large rocker can be operated to open a plurality of note holes including a medium bib hole and a medium hole;

In this mechanism, the floor plate is furthermore arranged, when it is actuated: on the one hand, to lift a square, called a large rocker, which pivots about said axis of ground and extends on the opposite side to said buffer Ground, so as to operate the big rocker; and on the other hand act on the round of Sol # so as to maintain it or bring it to the closed position of the hole of Sol #.

According to this aspect, this keying mechanism further comprises: on the one hand a Sol # drive part, carried by the bracket of big rocker or integral with it, and disposed on the same side of its axis, and on the other hand a Sol # receiving part which is carried by a Sol # heel, which is integral with the Sol # ring and disposed on the side with respect to its axis.

According to this same aspect, this Sol # drive part is further arranged to lift said Sol # receiving part so as to act on the round of Sol # to close or keep close the hole of Sol #, when the square of large rocker actuates the big rocker.

This "back" mechanism of Sol # represents a shorter length and is therefore stronger than the snake. It uses the same square as the big swing match, it exceeds less and is less likely to deform.

In cases where this part of the instrument remains integral, for example but not exclusively for an instrument according to the third aspect, the rear mechanism (or AR.) Of Sol # according to the first aspect of the invention makes it possible to make the operation more reliable. and minimize the risk of maladjustment.

It should be noted that this aspect of the invention can also be implemented on an instrument that does not conform to the first aspect, and for example as in the prior art of FIGURE 1 and FIGURE 2. Indeed, when the separation plane passes between the hole of Sol and the hole of Sol #, the rear mechanism ("AR mechanism") of Sol # according to this second aspect of the invention allows for example to minimize the risk of maladjustment, and facilitate the adjustments and verifications to be carried out with each reassembly of the instrument, which are particularly important for this type of separation.

The invention further provides a third aspect, possibly in accordance with the first aspect but which can also be implemented independently.

Typically, to play a note, we close all the holes to the hole of the note, and we open or leave open the latter. Some notes can be obtained with different configurations of the mechanism, or "fingering", or with different hole opening configurations, but that do not always give exactly the same sound and can sometimes produce sounds of different qualities. However, to play a given note, some configurations will be easier to use or others may be almost impossible according to the musical phases, for example according to the previous or subsequent notes and according to the desired speed or virtuosity of the user.

It is therefore useful to allow the use of fingerings more numerous and / or more adapted to different phases or sequences, or allowing improved sound quality.

With a mechanism according to the prior art, as illustrated in FIGURE 1 to FIGURE 3, the positioning of the fingers or "fingering" used to play a medium D is to press the Reb hole plate with the left hand, or plateau of 1/2 hole, leaving the plates of La and Si open (which is their situation at rest); and pressing the floor with the right index finger to open the holes of Do and Sib (which are normally closed). According to this third aspect, the invention proposes such a musical instrument of the oboe family, or a keying mechanism for such an instrument, in which the keying mechanism further comprises a maneuver element, said plateau of Do, which is movable by the user between a rest position and an actuated position, without the need to actuate the floor board. According to the second aspect, this plate of Do is arranged so that: the operation of the plate of Sol causes an actuation of said plate of Do, and the actuation of said plate of Do causes a closing support on the round of the ground # and a actuation of the big rocker.

According to different peculiarities of this aspect, the connection of the plateau of Sol to the plateau of Do is carried out according to one of the ways: the plateau of Sol causes the activation of the plateau of Do by an extension which extends over a first part of the upper surface of said plate of Do, and leaves a second portion of said surface accessible to the user to enable him to operate the plate of Do by pressing on said second part without actuating the ground plate. the floor plate causes the C plate to be actuated by a latching mechanism comprising a driving portion which is integral with the floor hinge and a receiving portion which is integral with the Do deck. According to this feature, these driving and receiving parts are arranged to cooperate together by supporting contiguous surfaces audite hinges, so that a rotation of the hinge of soil (produced by a support on the tray of soil) causes in rotation the hinge of Do and thus causes the actuation of the big rocker and the closing support of the round of Sol #. the tray of Sol causes the actuation of the plate of Do by a mechanism, extending on the rear side of their axis, including a training square integral with the plate of the hinge of Ground and a reception square solidary of the plate of Do . According to this feature, these driving and receiving brackets are arranged to cooperate together by supporting surfaces remote from their hinges, so that an uprising of the training square of the floor plate (produced by a support on the floor of Sol), causes an upright of the reception bracket of Do and thus causes the actuation of the big rocker and the closing support of the round of Sol #.

Thanks to this aspect of the invention, by pressing directly on the plateau of Do (rather than on the plateau of Sol), the user can thus perform a fingering allowing him to play a medium Do, but without the need to close the Ground hole.

The inventors have indeed determined that the sound thus obtained is slightly different and potentially of better quality. This additional tray allows you to play a more accurate Do, and to bring other "colors" sound, especially when you play a slow musical movement.

Thus thanks to its action of the big rocker, this new plateau of Do thus allows to play a medium Do without closing the hole of the Ground. The sound is different and its quality is improved. The invention further provides a method of making such an instrument or mechanism. According to the invention, this method is defined in that it comprises steps determined to produce all the characteristics of said device or instrument. Said method thus comprises, for one or the other of the exposed aspects and their peculiarities, all the characteristics which are exposed to it.

Various embodiments of the invention are provided, integrating, according to all of their possible combinations, the various optional features set forth herein.

Description of an exemplary embodiment

In all of the embodiments described here, the instrument shown is described in the form of an oboe in C (C). However, the same features are applicable and provided for other instruments of the same family, as discussed above according to the various aspects of the invention.

In the same spirit, the mechanisms described here operate according to a so-called "Conservatory" system, the details of which may vary according to the instruments or factors. It should be noted that the features of the invention described herein for a particular version of this mechanism are applicable to all versions that also exhibit the mechanism elements affected by these characteristics. For example, the features of the invention are applicable regardless of the presence or absence of different optional elements, such as for example the left F key or even the left # key, the Gillet key, or the octave key number. or trills, or the presence of a thumb tray, or other optional keys or independent of the affected mechanisms.

By convention herein is referred to as the "front" portion of the downward region of the figures representing the instrument with its bottom end (flag side) facing to the left and its top end (piperel side) facing to the right . The "back" part is thus the one situated towards the top of these figures. The direction of "uplift" is used to designate the movements that deviate from the surface of the tube of the instrument, that is to say "out" of the sheet in the figures. The "driving" direction is thus that which is close to the surface of the instrument.

In the figures, the note names used refer to the name of the hole on which the designated organ is located. That is to say for example that the reference "La" indicates the hole of La, that is to say the hole through which the sound of the note La. For example, the "plateau of Sol" is called because it is arranged on the hole of the ground, which is open at rest. The user activates the floor board by pressing it (usually with the index finger of the left hand) to close the hole in the floor. However, note that, by closing this hole of Sol, the sound goes out through the next open hole, for example that of the F # to play a Fa #. The sound played by pressing the Sol board will not be the Sol but the F #.

First embodiment

FIGURE 3 and FIGURE 4 illustrate a first embodiment of the invention in accordance with the first aspect set forth herein.

In this first embodiment, in accordance with the first aspect, the instrument comprises a top body and a bottom body which have different lengths.

Cutting plan

The upper body extends from the piperelle to the end of the E-hole. It carries the last ball of the Mi (lower) hinge. It also carries a part of the small rocker, whose training towards the resonance buffer Fa now forms a correspondence to the body of the bottom. This upper body has at its lower end a pin provided with a sealing cork, provided to fit into a socket of the bottom body.

The bottom body begins with the hole and the resonance mechanism Fa, as well as the axis of this mechanism. It carries the three elements forming the lever Eb, the lever of Do #, and the key of C serious, as well as their hinges and the balls which support them. The key of serious C carries two supports, here by adjusting screws. These support, for the highest one on the arm of the plate of Mi, and for that of the bottom on a lever acting the mechanism of the key of the fork, which involves in particular the opening of the small rocker. Due to the presence of the separation plane between the holes of Mi and Mib, these two supports are now separated during disassembly, and thus achieve two matches. They are, for example, unchanged in their form.

The lower body also carries the Gillet key and its axis. Preferably, it is gripped at its upper end by a ferrule, for example metal or composite fiber-based. This one preferably carries the balls of fixing of the key axis Gillet, as well as the end ball of the hinge of the key of serious Do. This bottom body extends to the last hole, that is to say the resonance hole Bb, and carries all the mechanisms located lower.

This lower body has at its lower end a pin and cork provided to fit into a socket of an element called flag, which here includes no side hole and no mechanism.

Thus, as can be seen, the upper body is longer than that of FIGURE 2 and descends lower. For its part, the lower body is shorter than FIGURE 2, but it goes lower. The pavilion is shorter and no longer has any lateral holes and especially no mechanism. Optionally, as shown in the upper half view of FIGURE 3c, the horn does not have a ferrule at all at its top end.

In this example, applied to an oboe in C, the roof is removable and the body of the top has a useful length (excluding post) of about twice that of the body of the bottom, with a difference of plus or minus 5cm, and in particular , ± 2cm.

More precisely, the body of the top has a length of 34cm ± 2cm, even ± 5cm; the body of the bottom has a length of 17cm ± 2cm, even ± 5cm; and the flag has a length of 9cm ± 1cm, even ± 1, 5cm. The body of the top thus has a length of about twice that of the body of the bottom, ± 2 cm, even ± 5 cm. By way of comparison, an instrument of the prior art such as that of FIG. 2 has, for example, two bodies of substantially equal useful lengths, for example representing 25.2 cm for the body of the top and 25.5 cm for the bottom body. , for a 13cm flag; that is to say with a body of the top which represents 39.7% of the total length once nested.

Match of crow's feet

The Conservatory-type keying mechanism comprises a set of maneuvering elements joined on the left side, arranged together obliquely and called "crow's feet". This crow's foot includes the Bb lever, the Si lever, and the Eb lever. These elements control in rotation an outer tube forming an "outer" hinge, and an inner rod called "steel" which is inserted inside this outer hinge. This steel is extended inside the outer hinge to an "inner" hinge, which is coaxial and integral with this steel, here by pinning.

In the prior art, for example as that of FIGURE 1 and FIGURE 2, the whole of this mechanism is entirely fixed to the body of the bottom.

In the invention, as illustrated in FIGURE 4, the inner hinge and the outer hinge are both separated into a lower part and an upper part.

The two parts of the inner hinge each carry a square, whose longitudinal ends cooperate with each other by support to form a so-called inner match, here provided with a set screw on its lower part. This internal correspondence can be separated and assembled and allow the disassembly and reassembly of the instrument.

The internal correspondence receives the movement of the inner rod, produced by the spatula of serious Si, and transmits this movement to the lower part of the instrument.

Similarly, the lower part of the outer hinge carries a bracket provided with an upwardly directed longitudinal end, and the upper part of the outer hinge carries a bracket provided with a longitudinal end facing downwards. These two ends cooperate with each other by support to form a so-called outer match, here provided with a set screw on its lower part.

The lever actuating the plate carrying the buffer of the lower Mi hole, which here has an "S" shape to join the lower side of this plate, is mounted on the body of the top. The start of this "Mi lever" is rotatably mounted around the inner link, above the inner hinge and below the outer hinge, as shown in FIGURE 3a.

As illustrated in FIG. 10, this "Mi" lever has a radial extension carrying a stop screw allowing a stroke adjustment. This stop screw bears on a "bow", forming a wafer extending radially integrally outside the outer hinge. From the outer hinge, this bow extends longitudinally downward to overtake the Mi starting lever then the inner hinge, and is supported on a short tube forming a reminder of the outer hinge, just before the fixing ball of end.

In the context of this new division, it should be noted that other mechanisms can be implemented to allow the separation in two of the transmission elements of the crow's foot mechanism, for example mechanisms of a known type. of the skilled person.

Second embodiment

FIGURE 5 illustrates a second embodiment, which will only be described in its differences. This second embodiment is consistent with both the first aspect and the second aspect set forth herein, the combination of which provides additional or improved benefits.

In accordance with the second aspect, the hinge of Sol no longer wears a snake at the front. In this second embodiment, in accordance with the second aspect, the floor bracket further carries a second longitudinal branch, here within the large flip-flop (ie front).

This second branch ends with a training match that supports under a reception match carried by a square of Sol #, formed by a longitudinal branch and a heel integral with the key of Sol # right, and integral with the round of Sol # on the other side of his hinge.

As it is understood in FIGURE 5, by pressing on the plate of Sol to close the hole of Sol, one raises the square of Sol, which raises the square of Sol #, which lowers the round of Sol # and closes thus the hole of Sol #. This "back" mechanism of Sol # thus fulfills the same role as the snake of FIGURE 1 to FIGURE 4.

Through the rear part of the ground bracket, the actuation of the ground plate simultaneously activates the large rocker.

As illustrated in FIG. 5, the correspondence of Sol # is actuated by a support between two surfaces, for example flat, between which is interposed a spring. As illustrated here, preferably but not necessarily, it is a leaf spring which is fixed by a blind screw on one of the correspondences, here that of receiving the square of Sol #. This spring is shaped and positioned, here a flat shape fixed at an inclined angle (for example between 10 ° and 30 °) so that its free end bears on the complementary correspondence and provides an elastic support on part of the race beforehand in direct contact between correspondences.

Third embodiment

In FIGURE 6 is illustrated a third embodiment of the invention, which will be described only in its differences. In addition to the first aspect, this embodiment of the invention is in accordance with the third aspect set forth herein, in that an additional tray is added beside the soil tray to the top of the instrument, which is referred to herein as " Do plateau ", although it does not cover any hole. This tray of Do is arranged to be operated by closing the tray of soil, but also to be itself directly operated by the user without the need to actuate or close the tray of soil.

Thus, when the floor plate is actuated to close the hole of the ground, it activates the plateau of Do, here by depression. This plateau of Do, it activates the big rocker and closes the round of Sol #.

Consequently, by transitivity, the support on the plate of Sol actuates the closing of the Sol # and the actuation of the big rocker, which produces an operation compatible with that of the prior art, and is useful for others. fingerings.

On the other hand, unlike in the prior art, it is now possible to actuate the large flip-flop and the closure of the Sol # by directly operating this plateau of Do, without touching the Soil plate and thus without having to close the Ground hole. This use of the Do plateau independently of the Sol plateau is illustrated by italicizing and dashing the elements of the Sol Plateau and their actions.

As illustrated in FIGURE 6, the keying of the instrument includes the additional Do deck in accordance with the third aspect, which actuates the large rocker and the closing of the Sol hole. In this embodiment, this actuation is done in a conventional manner, by two elements integral with a hinge: a rear bracket for the large rocker and a snake forward for the hole Sol #. However, unlike the prior art of FIGURE 2, these two elements are integral with the hinge of Do and not the hinge of Sol. This hinge of Do is rotatably mounted relative to the hinge of Sol, coaxial with it and separated by a simple ball attachment.

According to one feature, which can be applied to the embodiments that implement such a plate of Do, the floor hinge carries a rear bracket with a bearing surface. When the user presses on the floor board, this square square raises and presses under a square of Do which is integral with the hinge of Do. We thus obtain a rotation of the hinge of Do in the direction of the depression of the plateau of Do, that is to say that the hinge of Do actuates the big rocker and presses closing on the round of Sol #.

Thus, the actuation of the Soil Tray acts in accordance with the operation existing in the prior art of FIGURE 3.

However, when the user presses directly on the C deck without touching the floor board, the Do square is free to lift and allows him to operate the large rocker and close the floor while leaving the floor open. Ground hole.

It should be noted that this embodiment could be modified to implement the same plate of Do while using a cutting according to the prior art, for example that of FIG. 2. However, in the case of this new cutting, the space released and the strength obtained by this cutting with the upper body longer than the lower body facilitates the implementation of these new elements and their robustness.

Fourth embodiment

In FIGURE 7 is illustrated a fourth embodiment, which will be described only in its differences. In addition to the first aspect, this fourth embodiment of the invention is in accordance with the second aspect and the third aspect set forth herein, in that it includes both a backplane of Sol # and an extra tray of D.

In this exemplary embodiment, the soil plateau has a portion that protrudes above the plateau of Do, so that the support on the soil plateau causes a support on the plateau of Do. Other mechanisms for transmitting the actuation of the soil plateau on the plateau of Do are possible, such as those described above.

Of course, the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention.
