1. Field of the Invention
The present invention relates to a saxophone, and more particularly to a key mechanism for a saxophone.
2. Description of the Prior Art
A saxophone essentially comprises a plurality of keys disposed on a tubular instrument body, and the tubular body instrument body is formed with a plurality of sound holes. Each of the keys 10, as shown in
However, different players have different finger sizes, and the habits of pressing the keys are also different from player to player. Therefore, the saxophone won't be able to accommodate different players, if the touch pieces 12 cannot be adjusted. To solve this problem, the keys 10 are designed to be adjustable, wherein the touch piece 12 of each of the keys 10 is adjustably disposed in a slot 111 of the lever 11 by a slide block 121 and can be fixed at a desired position in the slot 111 by a fixing member 14. When the position of the touch piece 12 needs to be adjusted, a hand tool must be used to tighten and loose the fixing member. However, normally, a player won't take a hand tool with him or her all the time, which makes it the adjustment impossible or at least inconvenient. Besides, the height position of the touch piece 12 is restricted by the upmost holes of the slide block 121, and therefore cannot be freely adjusted.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a key mechanism for a saxophone, wherein the height position of touch piece of the saxophone can be easily adjusted without using any hand tools.
To achieve the above objective, the key mechanism for a saxophone in accordance with the present invention comprises: a lever, a sound-hole cover, an adjustment member, and a touch piece.
The lever is pivotally disposed on a tubular body of the saxophone, at one end of the lever is provided a connecting portion, and in the connecting portion is formed a non-circular rotation-stop hole extending in a first direction, and a slot in communication with the rotation-stop hole and extending in a second direction perpendicular to the first direction.
The sound-hole cover is disposed at another end of the lever.
The adjustment member is in the form of a nut with a threaded hole and rotatably disposed in the slot of the connecting portion of the lever, in a manner that the adjustment member partially protrudes out of the slot, and the threaded hole is in communication with the rotation-stop hole.
The touch piece is provided with a press portion, a rotation-stop portion and a screw. The rotation-stop portion is a non-circular column formed to fit the shape of the rotation-stop hole, the touch piece is inserted in the rotation-stop hole of the connecting portion, in a manner that the rotation-stop portion is engaged in the rotation-shaped hole, and the screw is screwed in the threaded hole of the adjustment member, rotating the adjustment member causes the screw to linearly move with respect to the adjustment member.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
The lever 20 is pivotally disposed on a tubular body of the saxophone by a pivot shaft 21 located between two ends of the lever 20. At one end of the lever 20 is provided a connecting portion 22, and in the connecting portion 22 is formed a non-circular rotation-stop hole 221 extending in a first direction D1. In this embodiment, the rotation-stop hole 221 is square-shaped, and in the connecting portion 22 is further formed a slot 222 in communication with the rotation-stop hole 221 and extending in a second direction D2 perpendicular to the first direction D1.
The sound-hole cover 30 is disposed at another end of the lever 20 and can either be integral with the lever 20 or removably attached thereto. The sound-hole cover 30 is aligned to a corresponding sound hole of the saxophone.
The adjustment member 40 is a nut with a threaded hole 41 and rotatably disposed in the slot 222 of the connecting portion 22 of the lever 20, in such a manner that the adjustment member 40 partially protrudes out of the slot 222, and the threaded hole 41 is in communication with the rotation-stop hole 221.
The touch piece 50 is sequentially provided with a press portion 51, a rotation-stop portion 52 and a screw 53. The rotation-stop portion 52 is a non-circular column formed to fit the shape of the rotation-stop hole 221. In this embodiment, the rotation-stop portion 52 is a square column. The touch piece 50 is inserted in the rotation-stop hole 221 of the connecting portion 22, in such a manner that the rotation-stop portion 52 is engaged in the rotation-shaped hole 221, and the screw 53 is screwed in the threaded hole 41 of the adjustment member 40, so that rotating the adjustment member 40 can make the screw 53 linearly move with respect to the adjustment member 40.
The lever 20 is pivotally disposed on the saxophone by the pivot shaft 21, pressing the press portion 51 of the touch piece 50 can make the lever 20 pivot with respect to the saxophone, and the pivot motion of the lever 20 then makes the sound-hole cover 30 open or close the corresponding sound hole of the saxophone, thus producing sound.
When the height position of the touch piece 50 needs to be adjusted, the user only has rotate the adjustment member 40 with respect to the screw 53, as shown in
It is understood from the above description that the touch piece 50 of the saxophone in accordance with the present invention can be easily adjusted without any hand tools.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
