Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stringed instrument support stand, and more particularly to a stringed instrument support stand that is supported by a tripod and is foldable for carrying or storage.

[Conventional technology]

Conventionally, support stands used to prop up stringed instruments for display or when not in use have adopted a disassembly structure for convenient portability and storage, but these disassembly structures still have shortcomings. be. For example, in a support stand used for a guitar, a bifurcated holding arm that holds the neck of the guitar projects horizontally from the upper end of the support stand, and cannot be folded up when stored. In addition to not being able to minimize the storage volume,
Since the opening angle of the holding arm is fixed and cannot be rotated in opposite directions, it is not possible to reliably grip the neck of the guitar. In addition, the support seat, which is made of pipe material in a U shape and installed horizontally at the bottom of the stand to support the bottom of the guitar's resonator body, cannot stably support the guitar, and the support seat is also placed opposite the protruding resonator body. It is bulky because it needs to be large. Furthermore, although some bearing seats allow the support angle of the bearing seat to be freely rotated around a horizontal axis, there is no angle restriction, so it is not possible to maintain stability.

[Problem that the invention attempts to solve]

In view of the above-mentioned deficiencies, it is an object of the present invention to provide a stringed instrument support stand that can be folded compactly with good stability and a small storage volume.

Another object of the present invention is to provide a string instrument support stand in which the holding arm can securely grip the neck of the string instrument.

Another object of the present invention is to provide a stringed instrument support stand that can stably support a stringed instrument by adjusting the support angle accordingly using a support device even if the center of gravity of the stringed instrument shifts to the left or right.

[Means for solving problems]

The gist of the present invention to achieve the above object is to provide a telescopic tube which is made up of a plurality of sections and has a tripod at its base and can be erected almost vertically; A neck clamp for holding the neck portion of a stringed instrument formed so as to be foldable along the axis of a telescoping tube; and a support device for supporting the body of a stringed instrument detachably attached to the lower section of the telescoping tube via a socket joint. Further, the tripod is a stringed instrument support stand that is pivotally attached to the base of the telescopic tube and is foldable along the axis.
