## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fixture, and more particularly to a fixture for a guitar stand to securely position the guitar via two arms.
2. Description of the Prior Art
After performance, the guitar player normally places the guitar against a wall to have a rest. However, the guitar against the wall is easily damaged since a gentle touch to the guitar will cause the guitar to slide to the floor and breaks it. In order to prevent such disaster from happening, an improved guitar stand is introduced to the market to position the guitar after performance. The guitar stand as disclosed in U.S. Pat. No. 6,513,768 ('768 hereinafter) has two levers each having a movable hook mounted at a free end of the lever such that when a guitar is placed against the two hooks, the weight of the guitar moves the two hooks closer to each other such that the neck of the guitar is substantially clamped by the two hooks. Therefore, the guitar is securely positioned on the guitar stand.
However, it is known from the disclosure of the '768 patent that there are provided with complicated components with complex structural relationships among the components. Thus the manufacture cost is high and the number on the price tag is not easily affordable by average people.
To overcome the shortcomings, the present invention tends to provide an improved fixture for a guitar stand to mitigate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an improved fixture to securely position the guitar, which is inexpensive and simple in structural relationships among components.
In order to accomplish the objective, the fixture of the present invention includes a seat having two compartments therein, a cap and two arms securely yet movable relative to the seat within the two compartments and along two arcuate slots in the cap such that the two arms securely engage with the guitar which is placed between the two arms.
In another objective of the present invention, the two arcuate slots respectively correspond to and communicate with the two compartments of the seat so that the movement of the two arms are confined by the compartments as well as by he two arcuate slots.
In yet another objective of the present invention, a resilient member is provided inside the seat to provide recovery force to the two arms such that after the guitar is removed from the fixture, the two arms are returned to their original positions by the recovery force.
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. 1 and 2, it is noted that the fixture (10) in accordance with the present invention is mounted on top of a stand (20) and includes a seat (30) which is firmly mounted on a free end of the stand (20), a cap (40) securely attached to a side of the seat (30), two arms (50) extending out from the seat (30) and a buffer (60) securely attached to a side of the cap (40) and between the two arms (50).
With reference t FIG. 3, it is noted that he seat (30) is provided with a centrally defined threaded hole (31), two compartments (32) separated from each other by the threaded hole (31), two moving blocks (33) respectively movable inside a corresponding one of the two compartments (32) and a resilient member (34) providing recovery force to the two moving blocks (33). A pivot hole (320) is defined in a bottom face defining the compartment (32) such that one end of a pin (331) is able to extend into the pivot hole (320). Each moving block (33) has a through hole (330) defined in a bottom end thereof to correspond to and receive therein the other end of the pin (331) such that each moving block (33) in the corresponding compartment (32) is pivotally retained and a connection hole (332) defined in a top end thereof. In addition, a side hole (333) is defined through a side of each of the moving blocks (33). A passage (35) is defined in the seat (30) to communicate the two compartments (32) with each other. In this embodiment, the passage (35) is defined at the bottom side of the seat (30). The resilient member (34) is an elongated plate with each of two free ends extending upward to become an abutting end (340).
The cap (40) is securely mounted on a side face of the seat (30) and has two arcuate slots (41) defined through the cap (40) to respectively communicate with the two compartments (32) of the seat (30) and an extension hole (42) defined through the cap (40) to correspond to and align with the threaded hole (31) of the seat (30). Each arcuate slot (41) is provided with a first position (410) and a second position (420).
Each of the two arms (50) has a tube (51), a protection tube (52) which is made of a soft material to receive therein the tube (51) and a hook (53) formed on a distal end of the tube (51) and having a protection covering (530) detachably mounted thereon. An engaging hole (54) is defined through a side of the tube (51) to correspond to and align with the side hole (333) of the moving block (33) so that an engagement pin (55) is extendable through the aligned engaging hole (54) and the side hole (333) to secure engagement between the tube (51) and the moving block (33).
The buffer (60) includes a T shaped rod, wherein a central rod of the T shaped rod is provided with a threading formed on a distal end thereof and extending through the extension hole (42) of the cap (40) after passing through a nut (62) and into the threaded hole (31) of the seat (30). An outer protection covering (63) is mounted on the T shaped rod to provide protection to the guitar.
It is noted that when the fixture of the present invention is assembled, one end of the two pins (331) is extended into a corresponding pivot hole (320) in the seat (30) and the other end of each of the two pins (331) is extended into a corresponding through hole (330) of a corresponding moving block (33) such that the two moving blocks (33) are able to pivot within the corresponding compartments (32). Then each tube (51) is extended through the protection tube (52), a corresponding arcuate slot (41) of the cap (40) and into a connection hole (332) of a corresponding moving block (33) to allow the engaging hole (54) to align with the side hole (333) of the corresponding moving block (33). The engagement pins (55) are then respectively extended into the aligned side hole (333) and the engaging hole (54) to secure engagement between the tube (51) and the moving block (33). After the engagement between the moving block (33) and the tube (51) is secured via the engagement pin (55), the pivotal movement of the two moving blocks (33) drives the two tubes (51) to move accordingly. It is further noted that because the tube (51) is extended through the arcuate slot (41), when the moving block (33) drives the tube (51) to move, the moving trajectory of the tube (51) is limited by the arcuate slot (41). That is, when the moving block (33) is pivoted and the corresponding tube (51) is driven to move accordingly, the tube (51) originally at the first position (410) is moved to the second position (411). Furthermore, the resilient member (34) is placed in the seat (30) with a body of the resilient member (34) received in the passage (35) and the two abutting ends (340) are respectively received in the two compartments (32) to abut a side face of the two moving blocks (33) so as to provide recovery force to the corresponding moving block (33).
With reference to FIGS. 4 and 5, after the fixture of the present invention is assembled and a guitar (70) is placed against the fixture with a neck (71) of the guitar (70) sandwiched between and engaged with the two arms (50), the weight of the guitar (70) on the two arms (50) drives the two arms (50) to move along the corresponding two arcuate slots (41). As stated before, movement of the two arms (50) drives the two moving blocks (33) to pivot inside the compartments (32) respectively since there is secured engagement between the corresponding moving block (33) and the arm (50). From the indication of the arrows, after the arms (50) move, the hooks (53) on the distal free end of each of the two arms (50) is moved closer to each other such that the guitar neck (71) is securely sandwiched between the two arms (50).
From the foregoing description, it is noted the structure is simple and thus the manufacture cost is low. Even though the structure is simple, the fixture of the present invention can still accomplish the designed goal, to position the guitar.
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.
