Description

Technical area

The invention relates to a device for fixing a single-tube sheet to the mouthpiece of a single-tube blower according to the preamble of claim 1. The saxophone and the clarinet are, for example, a single-tube blower.

Such a device must satisfy two conflicting needs: first, it must ensure that the single-tube blade is stably and reliably attached to the mouthpiece, and second, at the same time, allow the single-tube blade to swing freely, the more so the single-tube blade vibrate freely, the better will be the quality of the overtones that make up the timbre of the sound emitted by the wind instrument.

The device secures the single reed to the mouth of a single reed reed instrument by pressing the upper surface portion of the monoply reed against the lower surface portion of the die with the fasteners provided therewith. The effectiveness of these fasteners is controlled by dedicated regulation means provided to the device.

It should be noted that the ease with which a musician, regardless of his skill, is able to eject a sound from the single reed instrument, depends on the force with which the reed is pressed against the mouthpiece, ie, the force of the fastener. In general, the greater this force, the harder it is to eject notes from the wind instrument, so that the approach, ie, the beginning phase of the sound sequence, is more responsive, the rhythmic response of the wind instrument is fast, and the sounds tend to be bright. On the contrary, the smaller this force is, the easier it is to eject sounds from the wind instrument, so that the approach is softer, the rhythmic response of the wind instrument musical instrument is slow and the sounds tend to be muted.

State of the art

US 5,648,623 shows an apparatus for fixing a single-tube sheet to the mouthpiece of a single-tube blower according to the preamble of claim 1.

• ein Auflageelement, das mit einer Berührungsfläche auf dem oberen Oberflächenbereich des Mundstücks aufliegt;
• ein aktives Element, das mit einer Vielzahl von Aufnahmen versehen ist, in denen sich Abschnitte der mindestens einen Schnur erstrecken und / oder in denen die Enden der mindestens einen Schnur verankert sind;
• Verschiebungsmittel, die sowohl mit dem Auflageelement als auch mit dem aktiven Element zusammenwirken und auf das aktive Element wirken, um es entlang eine radiale Richtung des Mundstücks in beiden Richtungen zu verschieben, wobei die fortschreitende entlang besagte radiale Richtung sich vom Mundstück weg entfernende Bewegung des aktiven Elements eine gleiche fortschreitende durch Mitnahme verursachte Bewegung besagter Abschnitte bzw. besagter Enden der mindestens einen Schnur verursacht und dadurch in der mindestens einen Schnur eine Zugkraft erzeugt, deren Intensität entsprechend dem Wachstum der Bewegung fortschreitend größer wird.

In this known device, the fastening means on the lower surface portion of the single-tube sheet exert a fastening force pressing the upper surface portion of the single-tube sheet against the lower surface portion of the mouth piece, and comprise at least one string. This at least one string is arranged to extend at least along the lower surface portion of the single tube sheet and along the side surface portions of the mouth piece. The regulating means of this known device, which have to regulate the intensity of the force applied by the fastening means on the single-tube sheet, consist of means for generating an adjustable intensity pulling force in the at least one string. These means for generating an adjustable intensity pulling force in the at least one cord in turn comprise:

• a support member which rests with a contact surface on the upper surface portion of the mouthpiece;
• an active element provided with a plurality of receptacles in which portions of the at least one cord extend and / or in which the ends of the at least one cord are anchored;
• Displacement means cooperating with both the support element and the active element and acting on the active element to displace it along a radial direction of the mouthpiece in both directions, the progressive movement of the active movement away from the mouthpiece along said radial direction Element causes a same progressive entrainment movement of said sections or said ends of the at least one line and thereby generates in the at least one line a tensile force, the intensity of which increases progressively in accordance with the growth of the movement.

This known device differs from all other prior art devices in that the fastening means comprise at least one cord and therefore the regulating means comprise means for generating an adjustable intensity pulling force in the at least one cord. Namely, in the other devices of the prior art, the fastening means comprise rigid elements, but these rigid elements limit the freedom from vibration of the single-tube blade.

In contrast, in the known device according to the preamble of claim 1, in order to avoid the problems of restricting the freedom of vibration of the single-reed blade caused by the presence of the metallic elements in the fastener, the fact is utilized that the cord is not stiff

From US 5,648,623 Known device corresponding to the preamble of claim 1, therefore, represents an improvement compared to the known devices having fasteners containing rigid elements, but has some disadvantages.

A first disadvantage is the excessive size of the surface area of the single-tube sheet, which is affected by the action of the cord. Consider that with respect to the freedom of vibration of the single tube blade, the optimum situation would be that in which the single tube blade is attached to the mouthpiece in only one point. In the known device, the cord is arranged in the form of a spiral whose individual turns extend in a plurality of receptacles of the active element along the entire longitudinal extent of the active element, i. along the longitudinal direction of the mouthpiece, are evenly distributed, so that affected by the effect of the cord surface area of the single-tube sheet is remarkable in any case. The fact that the cords extend inside the active element also affects the quality of the final vibrations input to the wind instrument.

It is also unfavorable that the cords are welded at their ends to the receptacles, as this fact makes an easy replacement of the cord impossible power. There are many different types of wind instruments and the musicians play with different styles and have different opinions about the way the single reed must be attached to the mouthpiece, so there is not a single string that, in terms of its length and on the Material of which it is satisfying in all situations. It is therefore conceivable that each musician would like to choose between strings of different length and different materials depending on the wind instrument or type of music, but the known device does not allow this selection.

Another disadvantage is that in the known device there is a limited possibility to regulate the intensity of the tensile force. The particular design chosen for the support element, namely astride above the active element, entails that during the progressive movement of the active element away from the mouthpiece - the moving away movement is necessary to tension the cord - that active element is approaching more and more to the support element, which is why the active element must stop as soon as it touches the support element, and can move away from the mouthpiece not and this corresponds to the fact that you can not increase the tension in the string.

Presentation of the invention

The present invention is therefore based on the object to develop a known device of the type described above such that with the Einfachrohrblattblasinstrument on which the device is mounted, it is possible to optimally generate the full gamut of possible sounds, with a far-reaching regulation of the Intensity of the fastening force with which the single-tube sheet is attached to the mouthpiece and the possibility to use each of those string, which is suitable for the sound that you want to produce to be guaranteed.

This object is achieved by a device according to the preamble of claim 1, characterized in that such a device erfindungsgenäß additionally also having the features of the characterizing part of claim 1.

When the support element is disposed along said radial direction between the active element and the mouthpiece, as soon as the active element along said radial direction performs said movement away from the mouthpiece, it moves away from the support element rather than approaching it, as in the known device the case is. In other words, the support element no longer lies along the path of the active element and therefore no longer constitutes an obstacle which restricts the movement of the active element or restricts the adjustment range of the intensity of the tensile force and therefore the adjustment range of the fastening force. The active element can therefore be removed as far away from the mouthpiece as is necessary to stretch the cord in the desired manner. Thanks to the device according to the invention it is therefore possible optimally and as needed to press the single tube against the mouthpiece, since the intensity of the fastening force which applies the at least one string on the unit composed of the single tube and the mouthpiece in a wide range within a large adjustment is adjustable, but the intended direct proportionality between the regulatory movement is performed and the intensity of the resulting fastening force is applied attached, which ensures a remarkable regulatory precision. This also makes it possible to obtain a stable, reliable attachment adapted to the requirements of the musician, ie to eject an already prepared attachment in each case to tones which tend to be damped if the handle applied by the at least one string is not too strong, or sound tones that tend to be bright when the handle applied by the at least one string is very strong. This large adjustment range, which is made possible by the device according to the invention, makes the device adaptable to all the different different dimensions of the different different mouthpieces varying according to the different types of wind instruments.

The fact that the receptacles of the active element are arranged on projecting parts of the active element, which protrude from the main body of the active element and thus beyond the circumference of the upper Surface area of the mouthpiece on which rests the support element that the projections of said recordings on the mouthpiece are completely outside the upper surface portion of the mouthpiece on which rests the support element, also ensures that when the at least one string is stretched, this is completely outside of the upper Surface area of the mouthpiece extends on which the support element lies. This makes it possible to concentrate the fastening effect applied by the at least one line in two limited surface areas of the single tube sheet.

In this way, caused by the at least one string restriction of the vibration capabilities of the single reed is less than that was achievable to date with the known devices and the cord does not interfere with the vibrations of the single reed, which does not affect the quality of the overtones of which the sound ,

Thanks to the special arrangement of the at least one cord, as anticipated in claim 2, a particularly strong grip can be applied, which improves the reliability and the stability of the attachment.

The claims of 3 to 10 relate to a first embodiment of the device according to the invention and the claims of 11 to 17 relate to a second embodiment of the device according to the invention. More in detail, the following is presented.

The claimed in claims 3 and 4 features relate to a first possible embodiment of the recordings, which is characterized both by its constructive simplicity and because of its effectiveness and reliability in the interconnection of the active element and the at least one string.

The claimed in claim 5 features make the device symmetrical and thus allow the device can be fixed in a uniform manner on the mouthpiece.

The claimed in claim 6 features allow the at least one string can extend optimally and facilitate the attachment of the ends of the Recordings of the active element.

The claimed in claim 7 features make the device symmetrical and thus allow the device can be fixed in a uniform manner on the mouthpiece.

The features claimed in claim 8 facilitate the anchoring of one of the two ends of a string to the receptacles of the active element.

The claimed in claim 9 features relate to a possible embodiment of the displacement means, which is characterized by its simplicity, economy and reliability. A further advantage achieved with these displacement means in combination with the support element is that the fastening force applied by the at least one cord is transmitted by means of the screw and the support element only on a surface area of the mouthpiece and not on two separate surface areas of the mouthpiece , as it is, however, in the known device US 5,648,623 the case is. This entails that the vibrations of the single-tube blade are transmitted to the mouthpiece, which, in turn, vibrates, helping to create a reinforcing effect of the vibrations input to the instrument, and this makes the sound more full.

The features claimed in claim 10 enable the device to be held together and optimally positioned on the mouthpiece before tensioning of the at least one cord begins.

In claim 11, a second possible embodiment of the images claimed, which are intended to receive the portions of the at least one cord. The design of these recordings as grooves, whose longitudinal axis is bent in the direction of the mouthpiece, makes it possible for the cord sections to extend optimally and without friction along the receptacles.

In this case, the at least one cord is expediently formed from one or two cord rings, as claimed in claims 12 and 13. The presence of two lashes facilitates the formation of a larger number of fastening turns.

In claim 14, an embodiment of the images claimed, which are intended to receive the ends of the at least one cord. The design of these seats as L-shaped notches carved out of the walls of the groove and the fact that each end of the at least one cord is clamped within a ring provided with lateral projections adapted to fit in the notches, allow the ends of at least one string to anchor easily, reliably and accurately. The claimed in claim 15 features relate to a possible embodiment of the displacement means, which is characterized by its simplicity, economy and reliability.

In claim 16 it is claimed in particular that the support element has a cross section which has the shape of an inverted U, which minimizes the contact surface between the support element and mouthpiece and avoids that the head of the Zetrierschraube protrudes from the support element and the mouthpiece touches. The fact that the support element rests on the mouthpiece with rounded ends also makes the support element adaptable to the various curvatures of the various commercially available mouthpieces.

Finally, in claim 17 in particular bent wings are claimed, which facilitate the attachment of the device to the mouthpiece during attachment work. The positive connection provided according to the invention between the support element and the curved wing also allows easy assembly / disassembly of the curved wing on the support element and the decision whether the curved wings are to be attached or not and whether you want to use them as a useful accessory ,

Further advantages and features of the invention will emerge more clearly from the following description of exemplary embodiments of the device according to the invention, which are explained purely by way of example and approximately, but not in a restrictive manner, on the basis of the attached drawings.

Best way to realize the invention

In the figures, two embodiments of an apparatus for fixing a single-tube sheet 1 on the mouthpiece 2 of a Einzelrohrblattblasinstruments are shown. Such a single-bladed reed instrument is, for example, the saxophone or clarinet.

The attachment of the single tube sheet 1 on the mouthpiece 2 takes place in that the upper surface region of the single tube sheet 1 is pressed against the lower surface region of the mouthpiece 2. These two surfaces are generally flat.

The device comprises fastening means which on the lower surface portion of the single tube sheet 1 apply a fastening force pressing the upper surface portion of the single tube sheet 1 against the lower surface portion of the mouth piece 2 and comprise at least one string 13, 3 arranged as shown in Figs Figures 6 to 8 and 11 to 13 with respect to a first embodiment of the apparatus and in Figures 16 to 18 and also 25, 27, 29 and 30 with respect to a second embodiment of the apparatus is visible - that they 13, 3 at least along the lower surface portion of the single tube sheet 1 and along the side surface portions of the mouthpiece 2 extends

The device also comprises regulating means which regulate the intensity of the fastening force and consist of means for generating an adjustable intensity pulling force in the at least one cord 13, 3. The means for generating an adjustable intensity pulling force in the at least one cord 13, 3 in turn comprise: a support element 14, 4, an active element 15, 5 and displacement means 16, 15c, 6, 5c, 7.

The support element 14, 4 rests with a contact surface on the upper surface area of the mouthpiece 2.

With respect to the active element 15, 5, it is provided with a plurality of receptacles 15a, 15b, 5a, 5b and is connected to the at least one cord 13, 3 by means of these receptacles 15a, 15b, 5a, 5b. In the receptacles 5a sections 3a extend the at least one cord 3, such as from the FIGS. 26, 28 and 31 evident. In the receptacles 15a, 5b, 5b, the ends of the at least one cord 13, 3 anchored, such as from the Figures 5 . 19 and 24 evident. With respect to the displacement means 16, 15c, 6, 5c, 7, they cooperate with both the support element 14, 4 and the active element 15, 5 and act on the active element 15, 5 to move it along a radial direction of the To move mouthpiece 2 in both directions.

Since the portions 3a of the at least one cord 3 extend in the receptacles 5a of the active element 5 (see, as mentioned, for example FIGS. 26, 28 and 31 ) and / or the ends of the at least one cord 13, 3 are anchored in the receptacles 15a, 15b, 5b of the active element 15, 5, see, for example, as mentioned, for example Figures 5 . 19 and 24 5, the progressive movement of the active element 15, 5 away along the said mouthpiece 2 causes a same progressive entrainment movement of the sections 3a and the ends of the at least one cord 13, 3 and thereby generates in the at least one String 13, 3 is a tensile force whose intensity progressively increases in accordance with the growth of the movement. The fastening force which applies the at least one cord 13, 3 to the single-tube sheet 1 corresponds to this in FIG the at least one line 13, 3 generated tensile force.

According to the invention, the support element 14, 4 is arranged along said radial direction between the active element 15, 5 and the mouthpiece 2, as can be seen in particular from the figures from 1 to 4 with respect to the first embodiment and from FIGS FIGS. 21, 22 and 33 with respect to the second embodiment. This arrangement of the two elements 14, 15, 4,5 is different from that of the corresponding elements of the prior art device, and thanks to it , the active element 15, 5 moves away from the supporting element 14, 4, while 15; radial direction which carries away from the mouthpiece 2 away movement - movement which is necessary to tension the at least one cord 13, 3. With respect to, for example, the first embodiment of the device has been described in FIG. 4 the initial position of the active element 15 is shown while in FIG. 3 a possible offset position of the active element 15 has been shown. As can be seen from the comparison between these two figures, the active element 15 moves away from the supporting element 14, that is to say it moves away from the mouthpiece 2 which lies below the supporting element 14 (but this has not been shown in these figures).

The invention also provides, in particular from the figures of 1 to 4 in combination with the FIGS. 6 and 11 , from the FIGS. 21, 22 in combination with FIG. 23 or 25 or 27 and from FIG. 33 in combination with FIG. 30 it can be seen that the receptacles 15a, 15b, 5a, 5b are arranged on projecting parts of the active element 15, 5 which protrude from the main body of the active element 15, 5 and so on beyond the circumference of the upper surface area of the mouthpiece 2 on the 4, that the projections of the receptacles 15a, 15b, 5a, 5b on the mouthpiece 2 are completely outside the upper surface area of the mouthpiece 2, on which the support element 14, 4 rests. This makes it possible to concentrate the effect of the at least one cord 13, 3 on the smallest possible surface areas of the single tube sheet 1 and thus to come as close as possible to the ideal situation which provides for fastening in only one point. Conveniently, but not necessarily For example, each protruding part of the active element 15; 5, on which a receptacle 15a, 15b; 5a, 5b is arranged, may extend in a manner bent against the upper surface area of the mouthpiece 2.

In FIGS. 6 to 10, 16 to 20 and 25 to 26, the at least one string 13; 3 is arranged so as to additionally be wound at least once all around the unit formed of the single tube sheet 1 and the mouth piece 2 can and at least one fastening turn 13b, 3b forms in this way. Each fastening turn 13b, 3b extends in direct contact with the single tube sheet 1 and with the mouthpiece 2 along the lower surface portion of the single tube sheet 1 and along the side surface portions and the upper surface portion of the mouth piece 2. The fastening coils 13b, 3b wrap around the single tube sheet 1 and the handle formed by the mouthpiece 2 and the handle 13b, 3b are dependent on the tensile force with which the at least one cord 13, 3 is tensioned.

According to the invention and in relation to the first embodiment, each receptacle 15a.15b consists of a hook and one or more hooks 15b have a projection which extends outwards. In addition, on a first side of the active element 15 there is a first pair of hooks 15a, 15b and on a second side of the active element 15 opposite the first side there is a second pair of hooks 15a, 15b.

As is apparent from the figures relating to the first embodiment, ie the figures from 1 to 15, the at least one cord 13 can both be anchored with its ends to the hooks 15a, 15b and extend through them 15a, 15b. In addition, the at least one cord 13 can also be formed from two separate cords 13, one of which occupies the pair of hooks 15a, 15b disposed on said first side of the active element 15 and the other occupying the pair of hooks 15a, 15b, disposed on said second side of the active element 15. In the figures just this possibility was shown. For this purpose, it is expedient that each cord 13 has at one end a ring 13c, for example, characterized in that one end is formed in the form of a ring 13c, so that the ring 13c may conveniently be threaded onto one of the hooks 15a while the other end of the cord 13 is knotted around the hook 15b having the protrusion, see Figures 6 to 15.

Still with respect to the first embodiment, the displacement means consist of a screw 16 and a through threaded hole 15 c, which is additionally provided in the active element 15. The screw 16 is inserted into the through threaded hole 15c and is screwed and lies with its end 16c in a freely rotatable manner on the support member 14, in particular on the central body 14a of the support member 14, see for example the FIGS. 3 and 4 ,

The support element 14 consists of said central body 14a, on which the screw 16 rests in a freely rotatable manner, and of two arranged on the sides of the central body 14a magnetic lateral bodies 14b. These magnetic side bodies 14b cooperate with two projecting parallel magnetic bodies 15d of the active element 15, which are arranged on its 15 surface directed against the underlying support element 14. The object of these projecting parallel magnetic bodies 15d is to keep the active element 15 connected to the supporting body 14 during the positioning of the device on the mouthpiece 2 and by means of the force of magnetic attraction, before starting to tension the at least one cord 13. This situation is in FIG. 4 shown.

The magnetic force is expediently such that it is possible to manually slide the active element 15 relative to the support element 14 along the longitudinal direction of the mouthpiece 2, for example to regulate its position.

According to the invention and in relation to the second embodiment and as for example from the FIGS. 21 and 22 Each receptacle 5 a is conveniently bent from a groove whose longitudinal axis against the mouthpiece 2, while each receptacle 5 b is suitably transverse to the longitudinal axis of the groove 5 a and consists of an L-shaped pair of notches, each in the associated wall of the Groove 5a extends. Like from the FIGS. 21 and 22 in combination with the characters 19 and 24 In particular, each end of the at least one cord 3 is clamped in an associated ring 8 provided with lateral projections adapted to fit in the notches 5b. In FIG. 21 Ring 8 was also shown with dashed lines and in a virtual position, so that its structure is clearly visible. The anchoring of the ends of the at least one cord 3 by means of the blocking of the lateral projections of the ring 8 in the notches of the receptacle 5 b, as well as in the figures of 16 to 19 and in the FIGS. 23 and 24 is shown. The active element 5 also has a continuous threaded bore 5c, the function of which will be described below.

As can be seen from the figures relating to the second embodiment, ie Figures 16-34, the at least one cord 3 may be formed from a cord ring as shown in Figures 29-31 or two separate cord rings as shown in the Figures However, it can also consist of two separate ends provided with laces, as in the figures of 16 to 20 and in the FIGS. 23 and 24 is shown.

Still with respect to the second embodiment, the displacement means consist of a screw 6, of the through threaded hole 5c of the active element 5 and a centering screw. 7

The screw 6 has in its stem 6a at the end 6c of the screw 6 opening longitudinal threaded blind bore 6b and 6 it is also inserted into the through threaded hole 5c of the active element 5 and screwed, see the FIGS. 21 and 22 ,

The centering screw 7, however, is screwed into the longitudinal threaded blind bore 6b and longer than these 6b and it is also inserted in a through hole 4a of the support element 4. In this way, the centering screw 7 connects the screw 6 and the support element 4 such that the screw 6 can rotate freely relative to the support element 4, which causes the above-described removal of the active element 5 from the support element 4.

Finally, still with respect to the second embodiment of the Device according to the invention was in FIG. 22 a possible embodiment of the contact surface shown, with the support member 4 rests on the mouthpiece 2. According to this example, the support element 4 has a cross-section which has the shape of an inverted U, whose sides 4b extend transversely to the longitudinal direction of the mouthpiece 2 and with their ends form the contact surface with which the support element 4 rests on the upper surface region of the mouthpiece 2 , These ends of the sides 4b are rounded. As shown in particular in FIGS. 32 to 34, wings 4c made of an elastic material and curved towards the mouthpiece 2 may extend, which rest on the lateral surface area of the mouthpiece 2. These curved wings 4c indicate a modified embodiment of the second embodiment of the apparatus and may be provided for each embodiment, although they have been illustrated only in Figs. Each of the arcuate wings 4c has an enlarged and shaped end with which it is inserted 4c in a corresponding groove formed in the support element 4. The curvature of the curved wings 4c is smaller than the curvature of the side surface portion of the mouthpiece 2. Thanks to this curvature and its elasticity, the curved wings 4c nestle around the mouthpiece 2, thereby facilitating retention in the position of the device during its mounting on the mouthpiece 2.

With respect to the first embodiment of the device, i. those shown in Figures 1 to 15, the operation of the device according to the invention is as follows.

The first step to attach the device is to place the support member 14 with its mating surface on the mouthpiece 2. The magnetic attraction force keeps the parallel magnetic bodies 15d connected to the magnetic side bodies 14b, ie, supports the support member 14 and the active member 15 together, in the through threaded hole 15 c, the screw 16 is inserted. Should a person have difficulty holding the support member 14 on the mouthpiece 2, it can on the support surface of the Support member 14 attach a double-sided adhesive tape to temporarily adhere the support member 14.

Then you put the single tube sheet 1 on the mouthpiece. 2

Now, with respect to the embodiments of the figures, one must anchor the ends of each cord 13 to the respective pair of hooks 15a, 15b. For this purpose, one anchors on the hook 15a provided with the ring end of the cord 13 by threading the ring 13c on the hook 15a, and on the hook 15b, the end of the cord 13 which is without a ring, by this end, for example in the in the manner shown in the figures, knots on the hook 15b, where it is also possible to exploit the presence of the projection around which one can lead the cord 13 around. In general, however, each person can knot the string together as they prefer.

With regard to the formation of the possible fastening windings 13b, there will be commercially available cords 13 in different lengths, which is why all those who want to make at least one or more fastening windings 13b, cords 13 can buy in the appropriate length.

After the ends of the cords 13 have been anchored in the hooks 15a, 15b, the at least one cord 13 is tensioned by acting on the head of the screw 16, i. it is screwed into the through threaded hole 15c. The screwing of the screw 16 causes the movement of the active element 15 away from the mouthpiece 2 and the support element 14, respectively, and this moving movement tightens the at least one line 13. Because of the tensile force to which it is exposed, it brings at least one line 13 a fastening force on the single tube sheet 1, which blocks the single tube sheet against the mouthpiece 2.

With respect to the second embodiment of the device, i. that shown in Figs. 16 to 34, the operation is as follows.

There are minimal differences, depending on whether the at least one string 3 from a ring, see the figures 29 to 31, from two separate rings, see the figures of 25 to 28, or two separate strings, which in with rings 8 clamped ends are provided, see the figures of 16 to 20 and the FIGS. 23 and 24 , consists.

The first step to attach the device is to place the support element 4 with its contact surface on the mouthpiece 2. If curved wings 4c are provided, insert the mouthpiece 2 between the curved wings 4c, which, thanks to their elasticity and because of their curvature smaller than that of the mouthpiece 2, nestling around the mouthpiece 2.

Then you put the single tube sheet 1 on the mouthpiece. 2

Well, with respect to the embodiments of the figures of 16 to 20 and the FIGS. 23 and 24 ie those in which the at least one cord 3 is provided with ends clamped in rings 8, one anchors one end of the at least one cord 3 by inserting the lateral projections of the ring 8 in the notches of the associated receptacle 5b, so that by sliding in the Notches get the lateral projections in the angular parts of these notches. Thereafter, according to one of the types visible in the figures, the at least one cord 3 is placed around the unit formed by the single tube 1 and the mouthpiece 2 and finally anchored, with its ring 8 and in its respective seat 5b, also other end of at least one string 3.

In contrast, with respect to the embodiments of Figures 25 to 28 and 29 to 31, ie those in which the at least one cord 3 consists of two or only one ring, inserted in each cord ring 3, the unit consisting of the single tube sheet 1 and is formed from the mouthpiece 2, and it places in the grooves 5a, the portions 3a of each cord ring 3, which are located in the vicinity of the grooves 5a. The application example shown in FIGS. 29 to 31 is the only one which envisages the use of only one ring, and it differs from the other examples in that the active element 5 is rotated by 90 ° as compared to the other cases one by comparison between the FIG. 31 and the FIG. 19 or the FIG. 24 or the FIG. 26 or the FIG. 28 can recognize. In this example, the grooves 5a extend along the longitudinal direction of the mouthpiece 2 and not across it, as in the other examples.

With regard to the formation of the fastening windings 3b, there will be commercially available cords 3 as well as string 3 in different lengths, which is why all those want to form at least one or more mounting windings 3b, the cords 3 or the rings 3 can buy in the appropriate length.

After the cord portions 3a have been positioned in the grooves 5a or the lateral projections of the rings 8 have been inserted into the L-shaped notches, the at least one cord 3 is tensioned by acting on the head of the screw 6, i. it is screwed into the through threaded hole 5c. The screwing of the screw 6 causes the moving away from the support element 4 away movement of the active element 5 and this removing movement biases the at least one cord 3, which presses the single tube sheet 1 against the mouthpiece 2 and thereby blocked.
