## Title
Instrument support with two adjustable arms

## Abstract

An instrument support has a bracket provided with a first leg, a second leg, a disk and two forks. Each of the first leg and the second leg has a through hole defined in a side face of the first leg and second leg to communicate with an interior of the first leg and second leg to receive therein a spring-ball combination. A fork is movably and respectively received in the first and second legs and has an adjustable rod integrally formed with the fork and having recesses defined in a side face of the adjustable rod to correspond to the spring-ball combination so that movement of the two forks provide adaptation to thickness of different instruments.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an instrument support, and more particularly to an instrument support with two adjustable arms to adapt to instruments of different thickness.
2. Description of Related Art
An instrument support is to provide a specific instrument, such as a guitar or the like, a foundation on which to stand the instrument especially when the instrument can not stand by itself. With reference to FIG. 5, it is noted that a conventional instrument support has a first leg (10′) and a second leg (20′) jointing together with the first leg (10′) via a disk (12′). That is, a first end of the first leg (10′) is securely and fixedly connected to the disk (12′) and a first end of the second leg (20′) is pivotally connected to the disk (12′). The second leg (20′) has a handle (26′) pivotally connected to the second leg (20′) and has an extension (22′) formed on a distal end of the handle (26′) to alternatively correspond to positioning holes (14′) defined in the disk (12′) such that when the handle (26′) is pivoted, the extension (22′) is removed from the restriction of the positioning hole (14′) in which the extension (22′) is originally located and the extension (22′) is able to be relocated at a different positioning hole (14′) to adjust the angle between the first leg (10′) and the second leg (20′). What is more important is that the first leg (10′) and the second leg (20′) respectively have a base (11′,21′) to support the first and second legs (10′20′) on a surface and an arm (13′,15′) securely formed on a side face of the first and second legs (10′,20′). Therefore, when the conventional instrument support is placed on top of a surface, the instrument is able to be supported by the two arms (13′,15′) and the disk (12′). Although the instrument support does provide the required service to the instrument, there is no room for thickness change of the instrument. That is, when the instrument thickness using the instrument support is changed, e.g., from an electric guitar to an acoustic guitar, the two arms (13′,15′) can not provide the required supporting function to the new instrument. That is, the support from the two arms (13′,15′) is limited to a certain instrument with a specific thickness. With reference to FIG. 6, a different conventional instrument support is shown and has two arms (13A, 15A). Although the configuration of the two arms (13A, 15A) is different from that shown in FIG. 5, this instrument support still suffers from the same drawback as that of the instrument support shown in FIG. 5.
To overcome the shortcomings, the present invention tends to provide an improved instrument support to mitigate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an improved instrument support having two arms movably connected to the first and second legs such that the two arms are able to support instruments with different thickness.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1A, 1B, it is noted that the instrument support in accordance with the present invention has a bracket (1) and two forks (2).
The bracket (1) is able to stand by itself on a surface and has two legs (11), a disk (13) and a handle (15) in the preferred embodiment of the present invention.
One of the legs (11) is securely fixed to the disk (13) and the other leg (11) is pivotally connected to the disk (13). The handle (15) is pivotally connected to one of the two legs (11) and has an extension (151) extending from a distal end of the handle (15) to extend into a corresponding one of multiple positioning holes (131) in the disk (13). Therefore, when the handle (15) is pressed (pivoted) to allow the extension (151) to leave the restriction of the corresponding positioning hole (131) of the disk (13), the two legs (11) are able to move with respect to one another. Furthermore, the disk (13) has a cushion (132) formed on a front face of the disk (13) to be in engagement with an instrument to function as a damper. However, as the aforementioned cushion (132) is conventional in the art, detailed description thereof is thus omitted.
Each leg (11) has a hollow tube (111) extending outward therefrom and a through hole (113) defined in a side face of the leg (11) to communicate with an interior of the tube (111). A spring-ball combination (3) is provided in the through hole (113) so that the ball of the spring-ball combination (3) is able to selectively protrude from the through hole (113).
Each fork (2) is movably received in a corresponding one of the hollow tubes (111) and has an adjustable rod (21) integrally formed with the fork (2) and having recesses (211) defined in a side face of the adjustable rod (21) to correspond to a ball of the spring-ball combination (3).
With reference to FIG. 2 and still using FIG. 1 for reference, it is noted that after assembly of the present invention, the adjustable rod (21) is directly received in the corresponding tube (111) and the spring-ball combination (3) is received in the through hole (113) and secured by a cap (12).
With reference to FIGS. 3 and 4, it is noted that the operator is able to move the forks (2) relative to the bracket (1) to have the ball of the spring-ball combination (3) to be engageable in different recesses. After the adjustment of the projection length of the two forks (2) relative to the bracket (1), instruments of different thickness are able to be securely supported and clamped by the instrument support of the present invention.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
