Abstract
A dual-purpose support frame for a tuba and a support method thereof comprise a bottom (1), a left upright stanchion (2), a middle pole part (3), a cross rod (4) and a right support part (5). The bottom (1) is positioned below to play a role in overall stabilization, and a stainless steel counterweight is arranged in the bottom. The upper part of the left upright rod (2) is higher and slightly bent, so that the left part of the large size can be supported in an auxiliary way, and the left hand of a player can be convenient to support the size due to the bending. The middle rod part (3) abandons the common triangular bottom support, so that the support is more stable. The cross bar (4) makes the overall structure more stable. The right supporting part is detachably inserted at the right end of the cross rod (4) to provide a leaning position for inversion of a large size.
Description
Technical Field
The invention relates to the technical field of musical instrument supporting instruments, in particular to a dual-purpose support frame for tuba and a supporting method thereof.
Background
The tuba, or tuba, is a very important bass musical instrument. The brass instrument which is also called as a bass trumpet and is the lowest musical range in a orchestra or an orchestra is invented by the German Wei pleocide in 1835 years, is the youngest brass instrument, has very deep tone color, is used as the lowest tone part in a band, cannot be lacked by any symphony orchestra or orchestra for walking and carrying convenience, and basically has no function that other instruments can replace the trumpet.
In China, orchestra rarely see American jazz-shaped tuba horns sleeved on the waist, and most commonly see horn-shaped tuba horns. The number is carried in the chest with the back strap when the number is played in a standing state, and is mostly placed on the knees when the number is played in a sitting posture.
However, the grand size is large, the weight is large, and when a player needs to play in a sitting posture for a long time in a performance of a band, the player generally adopts a mode of placing the player on knees for supporting, but two problems exist, namely, the player needs to be straight to play while the thigh is stressed, the player is very tired, the average height is generally increased at present, the size of the grand size is not changed, and a great number of adults need to bend to adapt to the playing of the existing size of the grand size when the player needs to play in a sitting posture; thirdly, at present, many fun exercises and players are young children, the height of the large size is too high for the young children, the height of the small size is not suitable for being blown on the knees, other objects are often needed for supporting, and a better supporting mode is not provided. The playing mode of placing the large size on the thigh is inconvenient, and the existing technical problem is that no better and complete supporting means exists.
The large-size opening is placed underground, although the large-size opening can be generally placed, the large-size opening is unstable, the center of the large-size opening deviates to be far away from the central axis of the large-size opening when the large-size opening is placed upside down, and the large-size opening can be fallen down under the action of small external force. In the prior art, players sometimes lean the upside-down trumpet against a music rack or a chair in an attempt to prevent falls, but these are not specialized instruments and there is a risk of scratching and poor fixation of the trumpet.
We analyzed the prior art, and in the prior art, the most common large-size support is a commercially available HERCULES brand orchestra support, taking the most common DS553B type as an example, the lower part of the support is three support legs with adjustable angles, the middle part of the support leg is an inner sleeve and an outer sleeve, the upper part of the support leg is a very small arc-shaped support seat, the shape of the support leg is attached to the bottom of the large-size support, and the support leg can play a certain supporting role, but the determination is obvious.
Other related technologies also provide a dual-purpose supporting device for the orchestra tuba proposed by CN211980181U, which should be said to provide a good idea for dual-purpose placement of the tuba, but we have found through trial production that, because the tuba is placed at a symmetrical middle position, two large legs at both sides thereof are very in the way, so that the legs of the player are not placed at any place, and the practical use is very inconvenient.
Disclosure of Invention
The invention aims to provide a dual-purpose supporting device for a tuba, which is used for simultaneously solving the problems that the placing on the knee of a tuba in a sitting posture is easy to be tired in the prior art, and no stable supporting means is provided for inverting the tuba. Furthermore, compared with the HERCULES support, the support is obviously more stable, the problem of upside-down placement and leaning is solved, compared with the CN211980181U technology, the support is obviously shorter in the transverse direction, a player can put down legs comfortably, meanwhile, the support during playing is also more three-dimensional, and a lateral reinforcing support mode is provided.
