Abstract

The device for adjusting the length of a rope carrying a wind instrument has two parts that can be displaced into one another, wherein the first cup-shaped part has a notch and four openings, and the second part as an insert has a groove with a backward turning part, a notch and two guide grooves. A rope segment emerges from the device around the groove and is guided through the eye of the hook. Another rope segment is guided through the guide groove and the four openings. The device enables the guidance of the rope segment through the groove, which is completely separated from the guidance of the rope segment through the guide groove. The guide groove includes elements for deflecting the rope segment and suppressing the movement of the rope segment. The device enables stable and torsion-resistant operation of the rope length adjustment. The device makes it possible that the rope length cannot be adjusted autonomously even when the rope is not tensioned.

Description

Technical Field

[0001] The invention relates to a device for adjusting the length of a rope carrying a musical instrument, in particular a saxophone, a bass clarinet, a contrabassoon or a bassoon or a similar wind instrument. Background Art

[0002] Wind instruments such as saxophones are usually carried around the neck or shoulders due to their weight by means of a carrying device. Such a carrying device comprises a carrying belt, also called a carrying strap, which is placed around the neck, or a carrying frame which is placed on the shoulders, and a rope which is fastened on the one hand to the carrying belt or frame and on the other hand to the instrument by means of a hook. A carrying frame of this kind is disclosed, for example, in CH 704201. The carrying belt or the carrying frame with the rope enables the heavy instrument to be played for a longer period of time without the musician becoming too tired.

[0003] As disclosed in US 1,637,003, for example, a rope for such a carrying device is doubly wound around a hook, wherein the double loop is guided over a slide. The slide can be moved up and down, thereby changing the length of the double loop and the height position of the instrument. The slide comprises a square element, which is placed in a cup-shaped element together with a spring. The square and cup-shaped elements each contain an opening through which three sections of the rope can pass, in which the three sections are in contact with each other. When the spring is relaxed, the openings only partially overlap, so that the sections of the rope are clamped therein. The slide is held between the thumb and the finger, and in order to change the length of the rope, the thumb and the finger are pressed together, so that the square element is pressed into the cup-shaped element against the spring force, and the two openings overlap more. The rope sections in the opening have greater play, and the slide can move along the rope. If the thumb and the finger are released, the opening narrows, the rope sections are pressed together in the smaller opening, and the slide is stopped.

[0004] Other commercially available adjustment and clamping devices for musical instrument cords are adjusted in such a way that the loop of the cord is held very firmly by the adjustment element, which prevents accidental downward slippage, but makes readjustment during playing or during brief breaks in playing difficult.

[0005] Ropes are either round ropes or flat ropes. Round ropes are twisted or twisted with a circular cross section. Flat ropes are ropes with an elongated cross section like a belt. Summary of the invention

[0006] The object of the present invention is to provide a device for adjusting the length of a rope used to fix a musical instrument on a supporting device, which device can easily adjust the height of the musical instrument while preventing the device from slipping and the musical instrument from falling.

[0007] This object is achieved by a device according to claim 1 .

[0008] The device according to the invention for adjusting the length of the cord is designed to accommodate double and single cords and to vary the length of the cord guided in this way. The single-guided cord can be fastened to the neck or shoulder on a carrying device for the musical instrument, while the double-guided cord can be connected to a hook for the musical instrument.

[0009] The device for adjusting the length of a rope or a belt has two parts, namely a first part of cup-shaped design and an insert as a second part, which parts can be displaced or slid relative to each other and between which a spring is arranged.

[0010] According to the invention, the cup-shaped first part has a bottom and a surrounding edge, wherein a recess or an entry opening is arranged in its surrounding wall for guiding two rope segments or two belts through, and at least two further openings are arranged for the two rope segments or two belts. One or more first openings of the at least two further openings are arranged next to the recess or the entry opening, and one or more further openings are arranged opposite the first or multiple openings in the surrounding edge.

[0011] The second part of the device for adjusting the length of the rope or belt is designed as an insert in the cup-shaped first part and has a groove with a backward flip portion, which is formed by the surrounding edge and the central part of the insert part. The backward flip portion has a U-shaped or O-shaped shape. The surrounding edge of the insert has a notch introduced into the groove. The groove is used to receive at least one rope segment, which can be introduced into the groove through the notch, guided along the groove with the flip portion, and led out of the groove through the notch again. The rope segment guided in this way forms the shape of the backward flip portion according to the groove. The insert also has at least one channel for a rope or a belt, each channel is guided from the entrance next to the notch or the entrance opening to the exit opposite to the entrance. At least one channel has an element for deflecting and suppressing the movement of the rope, and is completely separated from the groove with the backward flip portion. That is, the notch or the entrance opening leading to the groove with the backward flip portion is completely separated from the entrance to at least one channel.

[0012] In a first embodiment, the cup-shaped first part has a bottom and a surrounding edge, in which recesses for two rope segments and four further openings for each rope segment are arranged. The first and second openings of the four further openings are arranged on both sides of the recess, and the third and fourth openings are arranged in the surrounding edge opposite to the first and second openings.

[0013] The second part of the length adjustment device is designed as an insert in the cup-shaped first part and has a groove with a backward flip portion, which is formed by the surrounding edge and the central part of the insert part. The surrounding edge of the insert has a notch for introducing the groove. The groove is used to accommodate the following rope segment, which can be introduced into the groove through the notch, guided along the groove with the flip portion, and led out of the groove again through the notch. The rope segment guided in this way forms the shape of the backward flip portion according to the groove. The insert also has two channels designed as guide grooves for the rope segments, which are arranged on the outer side of its surrounding edge and on both sides of the groove. By arranging the guide grooves on both sides of the notch, that is, arranging them sideways next to the notch, the guide grooves are respectively guided from the entrance next to the notch to the outlet opposite to the entrance. The two guide grooves also have elements for deflecting and inhibiting rope movement. The two lateral guide grooves are completely separated from the groove with the backward flip portion. That is, the notch leading to the groove with the backward guide portion is completely separated from the entrance leading to the lateral guide groove.

[0014] This embodiment is suitable for adjusting the length of a rope which is circular in cross section and extends elongated.

[0015] In one embodiment of the invention, the insert has a recess in its central portion for accommodating the spring.

[0016] In one embodiment of the invention, the elements for inhibiting the movement of the rope through the guide groove are formed by faces that are angled to each other. The faces that are angled to each other can meet each other at the tip or be connected to each other by another face. These elements cause the rope to be diverted in the guide groove in a simple zigzag manner and thus cause friction of the rope on the guide groove, thereby inhibiting the movement of the rope. If the device is held with the musical instrument in such a way that the rope is suspended in the vertical direction, as in use, the effect of the deflection element is that the rope in the guide groove is firstly directed laterally away from the vertical and then directed back again.

[0017] In another embodiment of the invention, the element for deflecting and inhibiting the movement of the rope through the guide groove comprises a protrusion in the cup-shaped first part, which extends vertically away from the inner bottom of the first part, and also comprises a notch in the insert, which is arranged in its surrounding edge. The notch in the insert is arranged corresponding to the position of the protrusion in the cup-shaped part, so that when the insert is inserted, the protrusion is embedded in the notch, extends through the notch and extends into the guide groove. Thus, the protrusion in the guide groove causes the rope in the guide groove to turn again in a simple zigzag shape, first deviating from the vertical direction at an angle, and then guiding back again.

[0018] In another embodiment, the cup-shaped part has a pin in the middle for fixing the position and orientation of the spring. Here, the pin is located according to the position of the recess in the insert so that when the insert is inserted into the cup-shaped part, the pin is inserted into the recess in the insert.

[0019] For the use of the first embodiment of the device according to the invention for adjusting the length of the rope, the first section of the rope is placed in the insert by placing the rope section in a groove with a turnover and leading its end out of the insert through a notch. The end is then fixed to a hook that can be mounted on a musical instrument, for example by passing the end through an eyelet on the hook. The insert with the rope in the backward turnover is then inserted into the first cup-shaped part in which a spring is placed. Here, the insert part prevents in the following way that the position of the notch with the rope section introduced and led out coincides with the position of the notch in the cup-shaped first part, and the rope section also passes through the notch in the first part. In use, the inlet and outlet of the two lateral guide grooves also coincide with the four openings in the cup-shaped first part. Then, in use, the two ends of the rope are passed through the opening in the cup-shaped part and the inlet of the lateral guide groove in the insert, through the guide groove of the insert, through the outlet of the guide groove and through the opposite opening in the cup-shaped part and are led out of the adjustment device again. Finally, secure the ends of the cord to the neck strap or instrument's carrying device.

[0020] The spring is positioned, for example, by a groove in the center of the insert and a pin in the cup-shaped portion.

[0021] The two parts of the device are held together by the positioning of the rope in the guide groove and in the four openings of the cup-shaped part. The rope segments are clamped between the entrance and exit of the guide groove in the insert and the edges of the openings in the cup-shaped part by the elastic force of the spring.

[0022] To adjust the length of the rope, the insert is pushed deeper into the cup-shaped part, compressing the spring there. As a result, the opening in the cup-shaped part coincides completely with the opening in the insert, so that the entrance to the guide groove becomes larger and the rope segment can move freely in the guide groove. The device can then be moved up and down (from the perspective of the musician) and the length of the double-guided rope segment, i.e. the length of the rope segment between the device and the hook on the instrument, is enlarged or reduced. When the required length is found, the pressure is released on the device, thereby relaxing the spring and moving the insert slightly out of the cup-shaped part again. The inlet and outlet of the lateral guide groove are reduced again in that the inlet and outlet in the insert no longer coincide exactly with the four openings in the cup-shaped part and become narrower.

[0023] Here, the inlet and outlet of the guide groove for the single-guided rope are narrowed again by slightly lifting the insert part from the cup-shaped part and pressing the rope segment in the opening of the cup-shaped part against its edge. As a result, the rope segment is clamped in the opening and held in position. The rope segment is thus clamped and stopped between the guide groove in the first cup-shaped part and the edges of the four openings. The length of the rope and the position of the instrument are thus kept constant.

[0024] In a second embodiment of the invention, the first cup-shaped part has an entry opening for passing two ropes or two belts. However, instead of four additional openings on the surrounding edge of the cup-shaped part, the cup-shaped part has only two additional openings. Therein, an opening is arranged next to the input opening for guiding two rope segments or two belts through, and the second opening is arranged on the surrounding edge of the cup-shaped part opposite to the first opening. The second part of the device, i.e. the insert, has only one channel designed as a through-portion, which leads from an entrance next to the recess to an exit opposite to the entrance. The channel has elements for deflecting and suppressing the movement of the rope or belt. The groove with the backward flip portion is completely separated from the entrance of the channel. That is, the recess leading to the groove is separated from the entrance of the channel.

[0025] This embodiment is suitable for adjusting the length of a flat rope or belt.

[0026] In one embodiment of the invention, the elements for inhibiting the movement of a rope or belt through the passage are formed by faces that are angled to each other. The faces that are angled to each other can meet at a tip or be connected to each other by another face. The angle between the faces is greater than 90°. These elements deflect the rope (for example a flat rope or belt) in a simple zigzag manner in the through-hole, so that the rope or belt rubs on the face of the through-hole, thereby inhibiting the movement of the rope or belt. If the device is fixed to the instrument during use so that the rope or belt is suspended vertically, the deflection element causes the rope or belt to deviate from the vertical direction first laterally in the through-hole and then return again.

[0027] In one embodiment, the insert has a recess in its central portion for accommodating the spring.

[0028] In order to adjust the length of a cord or a strap using the second embodiment of the device according to the invention, for example, two straps are placed one on top of the other. The straps are perforated near their free ends. The free ends of the two straps are then passed from the outside through the entry opening in the cup-shaped first part and are placed so that the holes in the straps are located above the recess in the bottom of the outer cup-shaped part. The insert is then inserted into the cup-shaped part with the center part, which passes through the hole in the strap by means of a spring and is embedded in the recess. The two parts are then engaged with each other and pressed together by means of a spring. The position of the notch together with the leading strap then coincides with the position of the entry opening in the cup-shaped first part, so that the strap is guided directly through the notch of the groove in the insert and through the entry opening in the cup-shaped part. The strap extending from the device is then fixed to a hook mounted on the musical instrument, for example by passing the end through an eyelet on the hook. The end of the overlapping strap is then passed through the first opening in the cup-shaped part and inserted into the inlet of the through-hole in the insert, through the through-hole of the insert, through the outlet of the through-hole and through the opposite second opening in the cup-shaped part and out again from the device for length adjustment. For this purpose, the openings in the insert and in the cup-shaped part are elongated and adapted to the cross section of the strap. Finally, the end of the strap is fixed to a neck strap or a carrying device of the musical instrument.

[0029] Based on the positioning of the band in the feedthrough and in the two openings of the cup-shaped part, the two parts of the device are kept together. Here, relying on the elastic force of the spring, these bands are clamped between the inlet and outlet of the feedthrough in the insert and the edge of the opening in the cup-shaped part.

[0030] To adjust the length of the band, as in the use of the first embodiment of the invention, the insert is pushed deeper into the cup-shaped part and the spring is compressed. As a result, the opening in the cup-shaped part completely coincides with the opening in the insert, so that the entrance to the through-hole becomes larger and the band can move freely in the through-hole. Then, (from the perspective of the musician) the device can be moved up and down and the length of the double-guided band, that is, the length of the band between the device and the hook on the instrument, can be enlarged or reduced. When the required length is found, the pressure is released on the device, thereby relaxing the spring and moving the insert slightly out of the cup-shaped part. The entrance to the through-hole is reduced again, because the entrance and exit of the through-hole no longer completely coincide with the two openings in the cup-shaped part and become narrower.

[0031] Here, the inlet and outlet of the guide groove for simple rope guidance are narrowed again by lifting the insert slightly out of the cup-shaped part and pressing the rope segment at its edge in the opening of the cup-shaped part. As a result, the strap is clamped in the opening and fixed in position. The straps are thus clamped and stopped between the guide groove in the first cup-shaped part and the edges of the two openings. The length of the strap and the position of the instrument remain unchanged.

[0032] The device according to the invention has the advantage over the prior art (particularly US 1,637,003) that the lateral guide groove in the insert is completely separated from the groove with the flip. In this way, the rope segments guided along the rearward flip in the middle groove in the insert for double guiding the rope do not come into contact with the rope segments in the lateral guide grooves of the insert. The rope segments in the multiple grooves extend in such an orderly manner that they do not touch each other and always remain oriented in the same direction. This makes it possible for the device according to the invention to always maintain the same orientation relative to the musician and to avoid twisting of the device and the rope. In addition, compared with the device according to US 1,637,003, the adjustment of the rope length requires less effort. This makes the use of the device easier and allows more rest when playing music.

[0033] The separation of the guidance of the cord segments in the grooves by means of the backwards folded parts and the guidance of the cord segments in the guide grooves of the inserts provides stability with respect to twisting of the device. Due to the separation of the cord segments, the device remains in the same position in that the bottom of the cup-shaped part is always on the same plane. The musician can thus grip the device more easily and reliably. The use of the device is simplified and quieter.

[0034] When the instrument is played, the rope is tensioned by the weight of the instrument. The elements for deflecting and damping the movement of the rope in the guide grooves provide stability of the respectively adjusted length of the rope by friction. If, on the other hand, the musician lifts the instrument with his hands, the rope is not tensioned. In this case, the clamping of the rope between the insert and the cup-shaped part of the device, which is achieved by the spring, ensures stability of the respectively adjusted length of the rope, which ensures that the rope length cannot be adjusted autonomously even when the rope is not tensioned.

[0035] After the desired rope length has been determined, the rope segments are held in position by means of elements for deflecting and damping the movement of the rope segments and by narrowing the entry and exit of the guide grooves. The rope thus does not loosen on its own during playing. Unwanted elongation does not occur. Since the rope segments are separated by mutually independent guide grooves, the rope remains intact after longer periods and frequent length adjustments, since the rope segments do not come into contact and do not rub against each other. The device according to the invention can therefore remain in use for a longer period of time. Saw teeth, barbs, etc. in the guides for securing the rope by friction are not required. Premature wear of the rope can be avoided.

[0036] The device according to the invention is suitable for all types of carrying devices for the musical instrument, including carrying devices with a carrying strap (carrying belt) on the neck and carrying devices with a carrying frame on the shoulder, wherein the rope sections can be fixed on the shoulder.

[0037] The device is particularly suitable for wind instruments such as saxophone, bass clarinet and contrabassoon.

[0038] Also disclosed is a carrying device for carrying a musical instrument, which has a carrying strap for the neck or a carrying frame for the shoulders, a rope or a belt, and a fixing part of the rope to the musical instrument, wherein the carrying device has a device according to the invention for adjusting the length of the rope as described above.

[0039] One embodiment of the carrying device has a hook with an eye for fastening the cord to the musical instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Figure 1 to Figure 2 A carrying device 1 is shown, for example, for a saxophone or similar wind instrument M, which has a carrying strap 2 (also called a carrying belt), which the musician wears around his neck and to which a cord 4 is fixed at the end. The cord 4 is introduced into a device 3 according to the invention for adjusting the length of the cord 4, which is led out again at the lower end of the device 3 and guided in a double loop or double strap through the eye of a hook 5. The hook 5 can be hooked onto the musical instrument M and fixed.

[0072] Figure 3 The carrying device 1 is shown slightly enlarged, in particular the two parts of the device 3, namely the outer first part 10 and the inner second part 20. The singly guided rope section 4 is passed from the carrying belt 2 through openings in the parts 10 and 20 and introduced into them at the upper end of the device 3. The doubly guided rope section 4 is passed through a further opening in the parts 10 and 20 and is guided to the eyelet 5' of the hook 5 at the lower end of the device 3.

[0073] Figure 4 Shown according to Figures 1 to 3 The cup-shaped first part 10 of the device according to the invention is circular in the embodiment shown and has a circular bottom 11 with a surrounding edge 12. A recess 13 is arranged at one point of the surrounding edge 12 for accommodating a doubly guideable rope section, such as Figure 5a As shown, it can be guided through a groove with a backward turn in the insert. Two openings 14 are arranged on both sides of the recess 13, through which another rope section can be guided. Opposite the two openings 14, two further openings 15 are arranged in the surrounding edge 12, through which the rope section can be led out of the device according to the invention. In this embodiment, a pin 16 is arranged in the center of the interior of the cup-shaped part 10 and serves to position the helical spring.

[0074] Figure 5a and Figure 5bAn insert 20 is shown which can be inserted into Figure 4 The shape of the insert 20 is adapted to the cup shape of the first part 10 and has an upper face 21 and a surrounding face 22. A recess 23 is arranged on the surrounding face 22. If the insert 20 is inserted into the first part 10, the insert 20 is surrounded by the surrounding edge 12, and the recesses 13 and 23 of the two parts 10 and 20 coincide in their position.

[0075] The insert 20 has a groove 24 which extends away from the notch 23 and forms a U-shaped or other similarly turned-back shape, the turn being approximately 180°. In the center of the insert 20 surrounded by the groove 24, there is a central portion 25 with a depression in which a spring 26 can be placed. When the insert 20 is inserted into the cup-shaped portion 10, the pin 16 is inserted into the depression and the spring 26.

[0076] The insert 20 also has two lateral guide grooves 28 in a symmetrical arrangement in the surrounding surface 22, which start from both sides of the recess 23 and extend along the surface 22 around a portion of the insert 20, the end of which is preferably on the side of the insert 20 opposite the recess 23. The guide grooves 28 are used to guide the rope segments. According to the invention, the guide grooves have elements for deflecting the rope and inhibiting the movement of the rope, that is, elements for deflecting and inhibiting the movement of the rope. In the embodiment shown, these elements are in the form of inclined surfaces 29, which are guided towards each other and meet at a tip 29'.

[0077] exist Figures 6a to 6c , the combination of the two parts 10 and 20 is shown, wherein the device 3 is shown in section. Figure 6a and 6c Also shown is the arrangement of the cable segments in the device 3 according to the invention.

[0078] First, the rope segment 4a is inserted into the insert 20, in particular into the groove 24 with the backward turn and is wound around the central part 25. The two ends of the rope segment 4a are then guided through the notch 23 of the insert 20 and the notch 13 of the cup 10 out of the device 3 and fastened through the eyelet 5' of the hook 5. After the eyelet 5', the two rope segments, now marked 4b, are guided back into the device 3 and through the opening 14 of the cup 10 and along the guide groove 28 of the insert 20. The rope segment 4b is then guided out of the guide groove 28 of the insert 20 on the opposite side and taken out of the device 3 again through the opening 15 of the cup 10. Afterwards, the rope segment (now marked 4c) is guided to the device 3 as shown in FIG. Figure 1-3The carrier belt or carrier shown. In the guide groove 28, the rope segment is guided along two adjacent faces 29 and around a face 29' connecting the faces 29, the rope segment being guided on the outside of the groove 28 by the inner face of the surrounding edge 12 of the cup-shaped part 10. The invention is characterized by the separate guidance of the rope segments 4a and 4b in that they are guided through separate openings or recesses 13, 14 and 23 and the rope segment in the groove 24 with the backward turn does not touch the rope segment in the lateral groove 28.

[0079] If the length of the rope is to be changed, the length of the rope segments 4a and 4b is changed, that is, the length of the double rope is extended or shortened. The length of the single-guided segment 4c is also changed accordingly. However, when adjusting the length, the portion of the rope in the groove 24 of the backward turning part always remains in place. Only the portion of the rope passing through the guide groove 28 moves. When the insert 20 is pressed into the cup-shaped part 10 against the force of the spring 26, the device 3 can move along the rope segment in the guide groove 28, so that the openings 14 and 15 are mostly overlapped with the entrance and exit of the guide groove 28. Then the device 3 can be moved up or down or the length of the rope can be shortened or extended. If the pressure on the insert 20 and the spring 26 is relieved, the spring relaxes and the insert 20 is slightly moved out of the cup-shaped part 10 again. Here, the entrance and exit of the guide groove 28 are narrowed and the rope segment is firmly clamped between the two parts 10 and 20.

[0080] Figure 8 Based on Figure 7 The section VIII-VIII in FIG. 3 shows the device 3 and the mechanism for clamping the rope segments in the device 3 when the spring 26 is relaxed. After the desired rope length has been selected, the insert 20 is slightly ejected from the cup-shaped part 10 by the spring 26. The guide groove 28 also moves so that its inlet and outlet move above the level of the openings 14 and 15 of the cup-shaped part 10 and the rope 4 in the guide groove 28 is clamped between the edges 14' and 15' of the openings 14 and 15 and one face 28' of the guide groove 28 in the insert 20. The movement of the rope 4 is thereby stopped.

[0081] The elements for deflecting the cord in the guide groove, the faces 29 of the guide groove 28 extending obliquely to one another, ensure by friction that the position of the device according to the invention does not change under the effect of the weight of the instrument. The greater the weight of the instrument, the greater the friction during deflection. The spring 26 between the cup-shaped part 10 and the insert 20 of the device mainly serves to stop the device when the instrument is lifted by the musician and the cord is not under tension and deflection does not generate friction.
