Description

TECHNICAL FIELD

[0001] The present application relates to the field of musical instruments, in particular to a tenor saxophone closer. BACKGROUND

[0002] The saxophone is a musical instrument invented by Adolphe Sax, a Belgian, in 1840. It is divided into high, medium, sub-medium, and upper bass types. The tenor saxophone is the most widely used and commonly seen on the market. Since the 1930s and 1940s, saxophone enthusiasts in China have been increasing rapidly, and saxophone playing has been introduced in major professional institutions.

[0003] The tenor saxophone has multiple tone holes distributed thereon, and each tone hole is provided with a key cover. The key cover includes a normally open key cover and a normally closed key cover, and the performer can play by controlling the opening and closing of different key covers. Figure 1 As shown in the drawings, the tenor saxophone 01 has a total of twelve normally open key covers 014, of which nine are arranged on the main pipe 011, one is arranged on the pipe bow 012, and two are arranged on the horn mouth 013. The opening and closing of the nine normally open key covers 014 on the main pipe 011 are not independent. Of these, six key covers 014 are independent of each other, and the other three key covers 014 are linked to the six key covers 014 through a linkage structure. When the six key covers 014 are all opened, the other three key covers 014 are all linked to open; when the six key covers 014 are all closed, the other three key covers 014 are all linked to close. Figure 2 As an example, any one of the six key covers 014 is connected to the corresponding first key rod 016 through the corresponding first connecting rod 015, the first key rod 016 is connected to the limiting block 018 through the second connecting rod 017, the first key rod 016 is rotatable and has a spring built-in, and the limiting block 018 abuts against the outer wall of the main pipe 011, thereby limiting the opening degree of the key cover 014. Figures 3-6 As shown in the drawings, there are a total of six such limiting blocks 018. Figures 7-8 As shown in the drawings, any one of the three normally open key covers 014 (i.e., the low C key cover 0141, the low B key cover 0142, and the lowered B key cover 0143) on the pipe bow 012 and the horn mouth 013 is connected to the corresponding second key rod 020 through the corresponding third connecting rod 019, the second key rod 020 is rotatable and has a spring built-in, and the key cover 014 abuts against the corresponding protective baffle 021, thereby limiting the opening degree of the key cover 014.

[0004] When the saxophone is left unused for a long time in different environments such as heat and humidity, the built-in leather pad of the normally open key cover 014 is prone to deformation, peeling, cracking, and other problems, and has a relatively short service life. At the same time, the leather pad is easily affected by temperature changes, causing sticking problems that affect the performance effect. If the leather pad needs to be replaced, it requires professional musical instrument repair personnel to operate, especially for high-end musical instruments, the cost of replacing the leather pad is relatively high. SUMMARY

[0005] The saxophone closer aims at solving the problem that the leather pad in the open key cover is easy to deform, peel and break, and has a short service life when the saxophone is left for a long time in different environments such as hot and humid.

[0006] In order to achieve the above object, the technical scheme adopted by the present application is as follows:

[0007] The saxophone closer comprises a main rope and a plurality of connecting ropes, one end of any connecting rope is connected with the main rope, and the other end is connected with a plug, and the plurality of plugs are used to be inserted between parts of the saxophone so that all the key covers on the saxophone are closed.

[0008] The saxophone closer of the present application adopts the above technical scheme, and the plurality of plugs are connected into a whole by the main rope and the connecting ropes to avoid the plugs from falling off. When the saxophone is left for a long time, the plurality of plugs are inserted into the saxophone to close all the key covers. When the key covers are closed, the leather pad is pressed on the sound hole to effectively prevent the leather pad from deforming, peeling and breaking. Compared with the prior art, when the saxophone is left for a long time in different environments such as hot and humid, the leather pad in the open key cover is easy to deform, peel and break, and has a short service life. The present application can make all the key covers of the saxophone in a closed state when the saxophone is left for a long time, effectively prevent the leather pad in the key cover from deforming, peeling and breaking in different environments such as hot and humid, and prolong the service life of the leather pad.

[0009] Further, the connecting ropes comprise six first connecting ropes and three second connecting ropes, the six first connecting ropes are connected with six first plugs respectively, and the three second connecting ropes are connected with three second plugs respectively. The six first plugs are used to be inserted between the outer wall of the main pipe of the saxophone and six limiting blocks respectively, and the three second plugs are used to be inserted between the low-pitch C key cover, the low-pitch B key cover and the descending B key cover and the corresponding protection baffle respectively. After the six first plugs are inserted into the above positions, nine open key covers on the main pipe are closed. After the three second plugs are inserted into the above positions, one open key cover (i.e. the low-pitch C key cover) on the pipe bow is closed, and two open key covers (i.e. the low-pitch B key cover and the descending B key cover) on the horn mouth are closed. In this way, all the key covers on the saxophone are closed.

[0010] Further, any first plug is a wedge-shaped block, and any second plug is a columnar block, two end faces of the columnar block are parallel to each other. The shapes of the first plug and the second plug are adapted to the structure environment of the saxophone. The first plug is set as a wedge-shaped block, which is convenient for being inserted between the outer wall of the main pipe of the saxophone and the six limiting blocks. The second plug is set as a columnar block, and the two parallel end faces of the columnar block are respectively abutted with the key cover and the protection baffle.

[0011] Further, the shape of any of the first plugs is a straight triangular prism with a right-angled triangle base, and the shape of any of the second plugs is a cylinder; the shapes of the first plugs and the second plugs are conventional, facilitating production and manufacturing.

[0012] Further, the height of any of the first plugs is h1, and the lengths of the two right-angle sides of the base are a and b respectively, h1 ranges from 1.8 cm to 2.2 cm, a ranges from 2.7 cm to 3.3 cm, and b ranges from 0.9 cm to 1.1 cm; the height of any of the second plugs is h2, and the diameter of the base is d, h2 ranges from 1.5 cm to 1.7 cm, and d ranges from 0.6 cm to 1 cm; the first plugs and the second plugs are set according to the above dimensions, and after being inserted into the alto saxophone, the normally open key cover can be tightly closed.

[0013] Further, the end of any of the connecting ropes is connected to the main rope through a double-hole spring buckle, and the end of the connecting rope and the main rope are respectively arranged in the two holes of the double-hole spring buckle; nine double-hole spring buckles are arranged along the length direction of the main rope; the double-hole spring buckles can be freely adjusted on the main rope, and are suitable for alto saxophones with different technical parameters.

[0014] Further, the length of the main rope ranges from 50 cm to 60 cm; the length of any of the first connecting ropes ranges from 13 cm to 17 cm; and the length of any of the second connecting ropes ranges from 27 cm to 33 cm; the lengths of the main rope, the first connecting ropes and the second connecting ropes in the above ranges are appropriate, which not only ensures that all the plugs can be inserted into the corresponding positions, but also avoids wasting materials due to excessively long ropes.

[0015] Further, the two ends of the main rope are respectively connected with a tail clip; this avoids the double-hole spring buckle from sliding off the end of the main rope.

[0016] Further, the main rope and / or the connecting rope is an elastic rope; the elastic rope has good toughness, and is avoided from being pulled off during use.

[0017] Further, the material of any of the plugs is silica gel or wood; silica gel or wood is a soft material, the plug made of this material is inserted more tightly, avoiding falling off, and at the same time, silica gel and wood are common materials, which are easy to obtain and have low manufacturing cost.

[0018] Compared with existing technologies, the advantages of this invention are as follows: when the saxophone is left unused for a long time, all key covers are in a closed state, effectively preventing the internal leather pads of the key covers from deforming, peeling, or cracking under different environments such as heat and humidity, thus extending the service life of the leather pads; it greatly reduces the problem of key sticking caused by temperature changes in the leather pads; the closure mechanism has a simple structure, and the double-hole spring buckle can be freely adjusted to the position on the main rope, making it suitable for alto saxophones with different technical parameters.

Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] This embodiment provides a soprano saxophone closure, such as Figures 9-11 As shown, it includes a main rope 1 and several connecting ropes; one end of any connecting rope is connected to the main rope 1, and the other end is connected to a plug; several plugs are used to insert between the various parts on the alto saxophone 01 so that all the key covers on the alto saxophone 01 are closed.

[0036] The connecting ropes consist of six first connecting ropes 2 and three second connecting ropes 3. The six first connecting ropes 2 are connected to six first plugs 4 respectively, and the three second connecting ropes 3 are connected to three second plugs 5 respectively. The six first plugs 4 are used to insert between the outer wall of the main tube 011 of the alto saxophone 01 and the six limiting blocks 018 respectively. The three second plugs 5 are used to insert between the bass C key cover 0141, the bass B key cover 0142, and the Bb key cover 0143 and their respective protective baffles 021 respectively.

[0037] Any first stopper 4 is a wedge-shaped block; any second stopper 5 is a columnar block, with the two end faces of the columnar block being parallel to each other; in this embodiment, the specific selection is as follows: the shape of any first stopper 4 is a right triangular prism with a right-angled triangle base, and the shape of any second stopper 5 is a cylinder;

[0038] The height of any first stopper 4 is h1, and the lengths of the two right-angled sides of its base are a and b, respectively. The range of h1 is 1.8cm to 2.2cm, the range of a is 2.7cm to 3.3cm, and the range of b is 0.9cm to 1.1cm. The height of any second stopper 5 is h2, and the diameter of its base is d. The range of h2 is 1.5cm to 1.7cm, and the range of d is 0.6cm to 1cm. Preferably, a = 3cm, b = 1cm, h1 = 2cm, h2 = 1.6cm, and d = 0.8cm.

[0039] The material of any stopper is silicone or wood; preferably, high-quality 15-degree silicone is used, which has the characteristics of elasticity, high temperature resistance and corrosion resistance.

[0040] like Figure 12 As shown, when the first plug 4 is inserted, the limiting block 018 lifts upward and disengages from the main pipe 011, thereby driving the first key lever 016 to rotate via the second connecting rod 017, and then the first connecting rod 015 drives the key cover 014 to cover the tone hole; when all six first plugs 4 are inserted into their corresponding positions, all nine normally open key covers 014 on the main pipe 011 close; as Figure 13 As shown, when the second plug 5 is inserted, the key cover 014 is pressed down by the second plug 5, thus covering the tone hole; when all three second plugs 5 are inserted into their corresponding positions, the three normally open key covers 014 on the bow 012 and the bell 013 (i.e., the bass C key cover 0141, the bass B key cover 0142, and the Bb key cover 0143) are all closed; therefore, when the first plug 4 and the second plug 5 are both inserted into their corresponding positions, all normally open key covers 014 on the alto saxophone 01 are closed.

[0041] The end of any connecting rope is connected to the main rope 1 through a double-hole spring buckle 6. The end of the connecting rope and the main rope 1 are respectively threaded through the two holes of the double-hole spring buckle 6. Nine double-hole spring buckles 6 are arranged at intervals along the length of the main rope 1.

[0042] The length of the main rope 1 ranges from 50cm to 60cm; the length of any first connecting rope 2 ranges from 13cm to 17cm; the length of any second connecting rope 3 ranges from 27cm to 33cm; preferably, the length of the main rope 1 is 55cm, the length of the first connecting rope 2 is 15cm, and the length of the second connecting rope 3 is 30cm; the diameter of the main rope 1, the first connecting rope 2, and the second connecting rope 3 is 4mm.

[0043] The main rope 1 is an elastic rope, preferably made of high-quality ultra-high molecular weight polyethylene rope, which has good toughness, ductility and ultra-high strength wear resistance, and is lightweight; the first connecting rope 2 and the second connecting rope 3 are ultra-high molecular weight acid and alkali resistant static braided ropes; the double-hole spring buckle 6 is an existing structure, with the diameter of the two holes being 5mm, preferably made of thermosetting plastic, which is hard, insoluble in solvents, and does not soften when heated;

[0044] Each end of the main rope 1 is connected to a tail clip 7; the tail clip 7 is an existing structure with a hole diameter of 4mm, made of high-quality polymer synthetic resin plastic material, with low processing cost and good formability.

[0045] The present invention, employing the aforementioned technical solution, connects several plugs into a single unit via the main rope 1 and connecting rope, preventing the plugs from falling off. When the saxophone is stored for an extended period, inserting several plugs into the saxophone closes all the keycaps. When the keycaps are closed, the leather pads are pressed against the tone holes, effectively preventing the leather pads from deforming, peeling, or cracking. Compared to the existing technology where the leather pads inside normally open keycaps are prone to deformation, peeling, and cracking under different environments such as heat and humidity when the saxophone is stored for a long time, resulting in a short service life, the present invention ensures that all keycaps remain closed during long-term storage, effectively preventing deformation, peeling, and cracking of the leather pads inside the keycaps under different environments such as heat and humidity, thus extending the service life of the leather pads. At the same time, it greatly reduces the problem of the leather pads sticking to the keys due to temperature changes. The closing mechanism has a simple structure, and the double-hole spring buckle can be freely adjusted in position on the main rope, suitable for alto saxophones with different technical parameters.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
