1. Field of the Invention
The present invention relates to a support stand for a keyboard of a musical instrument, and more particularly to a support stand which can steadily support a keyboard of a musical instrument.
2. Description of Related Art
Generally, a keyboard of a musical instrument such as an electric piano or synthesizer is retained at one of a variety of heights by a conventional supporting stand when a performer is playing the musical instrument. Hence, the height of the musical instrument can be adjusted to a proper location for the performer and the musical instrument can be steadily supported.
With reference to
When the user wants to adjust the conventional supporting stand for the musical instrument, the user must pull the shank (74) thereby compressing the coil spring (75) with one hand so that an end of the shank (74) can move out of the opening (72). Furthermore, the user should adjust the first rod (73) relative to the second rod (73a) in an angle by using the other hand and therefore, the user requires the other person's help to support the second rod (73a).
Additionally, a top angle between the first and second rod (73, 73a) is adjusted relative to a lower angle between them such that the conventional supporting stand for the keyboard of the music instrument can not achieve an effect that both of the top and the lower angle are small or both of them are big.
Furthermore, the first and second rod (73, 73a) can not be folded with the conventional supporting stand for the musical instrument and therefore, it is inconvenient to store the stand.
Therefore, the invention provides a support stand for a keyboard of a musical instrument to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a supporting stand for a keyboard of a musical instrument with which it is easy to adjust an angle between shanks of the present invention and it is convenient to store the stand.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
Each supporting member (10) has two arcuate portions (11) formed on two sides thereof, multiple channels (110) defined in the periphery of the corresponding arcuate portions (11), and a first hole (12) respectively defined in a center of circle of each arcuate portion (11). Two caps (13), which are provided on an outer wall of the supporting members (10), respectively have two second holes (14) corresponding to the first holes (12) and an opening end in a lower end thereof.
Each leg (20), which can be inserted into the opening end of the caps (13), has two parallel shafts (21) provided on thereof, multiple symmetrical openings (22) defined in a top end of the shaft (21) and a first foot (23) provided on a lower end of and perpendicular to the shaft (21).
Each shank (30), a top end of which can be attached to the respective supporting member (10), has multiple first apertures (31) defined in a first end thereof, and a second foot (32) mounted on a second end thereof and perpendicular thereto. The positioning member, which can be engaged with the channels (110), is mounted on the shanks (30).
The pivotal members (50) are respectively inserted into the second holes (14), the openings (22), the first holes (12), and the first apertures (31) in turn so that the legs (20) can be pivotally mounted between the caps (13), and the shanks (30) can be provided between the supporting members (10). In a first preferred embodiment of the present invention, the pivotal members (50) are nuts and bolts.
Also in the first preferred embodiment of the present invention, each shank (30) comprises an inner tube (34) and an outer tube (33). Multiple symmetrical first apertures (31) are provided in a first side end of the outer tube (33) and multiple threaded holes (330) are defined in a second side end of the outer tube (33). The inner tube (34), a first end of which is inserted into the outer tube (33), has the second foot (32) mounted on a second end thereof and perpendicular thereto, and multiple evenly-spaced second apertures (340) defined in an axial periphery thereof. A screw rod (35) can be inserted into the threaded holes (330) and the second apertures (340). A hollow barrel (36) is mounted in an interior of the outer tube (33) to decrease the friction between the inner tube (34) and the outer tube (34). A through hole (360) corresponding to the threaded holes (330) is defined in the hollow barrel (36) so that the inner tube (34) is inserted into the hollow barrel (36) and fastened via the screw rod (35) being inserted into the second apertures (340) after the screw rod (35) is received into the threaded hole (330) and the through hole (360).
With reference to
With reference to
Additionally, when the shanks (30) are adjacent to the legs (20), it is easy for the supporting stand for the keyboard of the musical instrument to be stored via decreasing the volume of the present invention.
With reference to
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.
