Description

Technical Field

[0001] The invention relates to the field of musical instruments, in particular to a closer for an alto saxophone. Background Art

[0002] The saxophone was invented by Belgian Adolphe Sax in 1840. It is divided into soprano, alto, tenor, and baritone models. The alto saxophone is the most widely used and the most common on the market. Since it entered China in the 1930s and 1940s, the number of saxophone enthusiasts in my country has been increasing rapidly, and major professional colleges have also opened saxophone performance majors.

[0003] There are multiple sound holes on the alto saxophone, each of which is provided with a key cover, including a normally open key cover and a normally closed key cover. The player can play by controlling the opening and closing of different key covers; Figure 1 As shown, there are twelve normally open key covers 014 on the alto saxophone 01, nine of which are arranged on the main pipe 011, one on the bow 012, and two on the bell 013. The opening and closing of the nine normally open key covers 014 on the main pipe 011 are not independent, six of which 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 opened, the other three key covers 014 are also linked to open; when the six key covers 014 are all closed, the other three key covers 014 are also linked to close; Figure 2 For 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, and the first key rod 016 is connected to the limit block 018 through the second connecting rod 017. The first key rod 016 is rotatable and has a built-in spring. The limit block 018 abuts against the outer wall of the main pipe 011, thereby limiting the opening degree of the key cover 014; Figure 3-Figure 6 As shown, there are six such limit blocks 018. Figure 7-Figure 8 As shown, any one of the three normally open key covers 014 (i.e., bass C key cover 0141, bass B key cover 0142 and B flat key cover 0143) on the bow 012 and the bell 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 built-in spring. The key cover 014 abuts against the corresponding protective baffle 021, thereby limiting the degree of opening of the key cover 014.

[0004] When the saxophone is not used for a long time, in hot, humid and other environments, the built-in leather pads of the normally open key cover 014 are prone to deformation, peeling, cracking and other problems, and the service life is short; at the same time, the leather pads are easily affected by temperature changes, causing sticking keys and affecting the performance effect; if the leather pads need to be replaced, professional instrument repairmen are required to operate, especially for high-end instruments, the replacement cost of the leather pads is relatively high. Summary of the invention

[0005] The purpose of the present invention is to provide a saxophone closer to solve the problem that when the saxophone is left unused for a long time in hot, humid and other environments, the leather pad inside the normally open key cover is easily deformed, peeled and cracked, and the service life is short.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A alto saxophone closer comprises a main rope and a plurality of connecting ropes; one end of any of the connecting ropes is connected to the main rope, and the other end is connected to a plug; the plurality of plugs are used to be inserted between various parts on the alto saxophone to close all key covers on the alto saxophone.

[0008] The present invention adopts the above-mentioned technical scheme, connects several plugs into a whole through a main rope and a connecting rope to prevent the plugs from falling; when the saxophone is left for a long time, all the key covers are closed by inserting several plugs on the saxophone, and the leather pads are pressed on the sound holes when the key covers are closed, which effectively prevents the leather pads from deformation, peeling and cracking; compared with the prior art, when the saxophone is left for a long time, in different environments such as hot and humid, the built-in leather pads of the normally open key covers are prone to deformation, peeling and cracking, and the service life is short in different environments such as hot and humid. According to the present invention, all the key covers of the saxophone can be in a closed state when the saxophone is left for a long time, which effectively prevents the built-in leather pads of the key covers from deformation, peeling and cracking in different environments such as hot and humid, and extends the service life of the leather pads.

[0009] Furthermore, the connecting ropes include six first connecting ropes and three second connecting ropes, the six first connecting ropes are respectively connected to six first plugs, and the three second connecting ropes are respectively connected to three second plugs; the six first plugs are respectively used to be inserted between the outer wall of the main pipe of the alto saxophone and the six limit blocks, and the three second plugs are respectively used to be inserted between the bass C key cover, the bass B key cover and the B flat key cover and their corresponding protective baffles; after the six first plugs are inserted into the above positions, the nine normally open key covers on the main pipe are closed; after the three second plugs are inserted into the above positions, a normally open key cover (i.e., the bass C key cover) on the bow is closed, and the two normally open key covers (i.e., the bass B key cover and the B flat key cover) on the bell are closed; in this way, all the key covers on the alto saxophone are closed.

[0010] Furthermore, any one of the first plugs is a wedge-shaped block; any one of the second plugs is a columnar block, and the 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 structural environment in which they are inserted into the alto saxophone, and the first plug is set as a wedge-shaped block, which is convenient for inserting between the outer wall of the main tube and the six limit blocks of the alto saxophone; the second plug is set as a columnar block, so that the two parallel end faces of the columnar block are respectively abutted against the key cover and the protective baffle.

[0011] Furthermore, any one of the first stoppers is in the shape of a right triangular prism with a right-angled triangle bottom surface, and any one of the second stoppers is in the shape of a cylinder; the shapes of the first stopper and the second stopper are conventional, and are convenient for production and manufacturing.

[0012] Furthermore, the height of any one of the first plugs is h1, the lengths of the two right-angled sides of the bottom 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 one of the second plugs is h2, the diameter of the bottom is d, the range of h2 is 1.5cm to 1.7cm, and the range of d is 0.6cm to 1cm; the first plug and the second plug 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] Furthermore, the end of any one of the connecting ropes is connected to the main rope via a double-hole spring buckle, and the end of the connecting rope and the main rope are respectively inserted into two holes of the double-hole spring buckle; nine double-hole spring buckles are arranged at intervals along the length direction of the main rope; the double-hole spring buckle can freely adjust its position on the main rope, which is suitable for alto saxophones with different technical parameters.

[0014] Furthermore, the length range of the main rope is 50cm to 60cm; the length range of any one of the first connecting ropes is 13cm to 17cm; the length range of any one of the second connecting ropes is 27cm to 33cm; the main rope, the first connecting rope and the second connecting rope in the above length range are of appropriate lengths, which ensures that all plugs can be inserted into corresponding positions and avoids wasting materials due to excessive rope length.

[0015] Furthermore, each end of the main rope is connected to a tail clip buckle to prevent the double-hole spring buckle from slipping off the end of the main rope.

[0016] Furthermore, the main rope and / or the connecting rope are elastic ropes; the elastic ropes have good toughness and can avoid being broken by stress during use.

[0017] Furthermore, the material of any of the plugs is silicone or wood; silicone or wood are both soft materials, and the plugs made of this material can be inserted more tightly to avoid falling off. At the same time, silicone and wood are both common materials, easy to obtain, and have low manufacturing costs.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: when the saxophone is left unused for a long time, all key covers are in a closed state, which effectively prevents the built-in leather pads of the key covers from deformation, peeling and cracking in hot, humid and other different environments, thereby extending the service life of the leather pads; greatly reduces the problem of sticking keys caused by temperature differences; the closer has a simple structure, and the double-hole spring buckle therein can be freely adjusted to its position on the main rope, which is suitable for alto saxophones with different technical parameters.
