Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a keyboard stand stopper which is mounted on a keyboard stand on which a keyboard is installed and which prevents the keyboard from being displaced during a performance.

[Outline of the invention]

The present invention is directed to a stopper body which is mounted so as to straddle on a frame of a keyboard stand and has an elastic member adhered to a surface facing the upper surface of the frame, and a clamp rotatably supported on both side pieces of the stopper body. The position of the keyboard mounted on the frame by rotating the clamp lever to pull the stopper body toward the frame, compressing the elastic member and clamping the stopper body to the frame. This is to prevent the displacement.

[Prior art] Conventionally, in a keyboard stand of this type, a plurality of stoppers are fixed on a frame by screws or the like, or a frame is bent to form a stopper integrally, and the like. The front and rear positions of the keyboard were regulated to prevent the displacement.

[Problems to be solved by the invention]

However, in such a conventional keyboard stand stopper, since the stopper is fixed on the frame in accordance with the keyboard of a specific size (depth length), it is widely used for keyboards of other sizes. There was a problem that it could not be handled.

The present invention has been made in view of the above points, and has as its object to provide a keyboard stand stopper which has a simple configuration and can be easily adjusted in position.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a stopper main body which is erected on a frame of a keyboard stand by erecting a stopper piece for locking a keyboard, and a stopper body below the lower surface of the frame of the stopper body. The clamp comprises a clamp lever which is detachably attached to both side pieces extending to the side, and which is rotatably supported by the side pieces at the time of mounting, and an elastic member attached to a surface of the stopper body opposite to the upper surface of the frame. The elastic member is compressed by the clamp lever and the stopper body by the rotation of the lever to clamp the frame, thereby clamping the stopper body to the frame.

[Action]

By configuring the stopper of the keyboard stand according to the present invention as described above, the stopper body is placed so as to straddle the frame, and after attaching the clamp lever to both side pieces of the stopper body extending downward from the lower surface of the frame, When the clamp lever is rotated after the stopper body is moved to a position corresponding to the required keyboard, the stopper body is pulled downward, the elastic member is compressed, the frictional force with the frame is rapidly increased, and the stopper body is moved to the frame. Can be firmly fixed at the required position.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the present invention, and FIG.
The figure is a perspective view of a keyboard stand embodying the present invention.

First, the overall configuration of a keyboard stand embodying the present invention will be briefly described with reference to FIG.

This keyboard stand 20 is formed by bending a hollow pipe material having a rectangular cross section into a U-shape to form a pair of frames 2 having the same shape.
1, 21 are formed, legs 22, 22 are erected on the opening side, and the frames 21, 21 are screwed openably and closably at their bases, and the frames are expanded between the legs 22, 22 in a state where the frames are expanded by a predetermined angle. 23 was erected and fixed.

The fixed stoppers 24 having the stopper pieces 24a erected on the upper surfaces of the respective end portions of the frames 21, 21 are fixed by screws, respectively, to form front stoppers of the keyboard. Further, a plurality of rubber feet 25 with which the bottom surface of the keyboard abuts are mounted on each frame 21, and the stopper 10 according to the present invention is mounted behind the rubber feet 25.

The stopper 10 is, as shown in FIG.
And a clamp lever 12.

The stopper body 11 includes a stopper piece 11b that rises substantially perpendicularly from the substrate 11a, and a pair of side pieces 11c that bend downward from both sides of the substrate 11a and extend downward in contact with both side surfaces thereof when attached to the frame 21. , 11c, and the frame 21 of the side piece 11c
J with one end open forward at the part extending below
A U-shaped groove 11d is formed. Further, an elastic member 13 such as sponge, rubber or the like is attached to the lower surface of the substrate 11a.

On the other hand, the clamp lever 12 is formed by bending a plate material into a deformed U-shape in which the opening side is expanded, and the width thereof can be inserted through both side pieces 11c, 11c of the stopper body 11 side,
In the figure, protrusions 12b, 12b are integrally formed on both sides of the first side 12a on the upper side, and the protrusions 12b, 12b are formed on the both side pieces 11c, 11c.
11d, so that it can freely rotate within 11d.

This embodiment is configured as described above,
At the time of mounting on the frame 21, after placing the stopper body 11 so as to straddle the frame 21, the grooves 11d, 11d of the both side pieces 11c, 11c.
Then, the protrusions 12b, 12b of the clamp lever 12 are inserted into the frame (FIG. 3 (c)), and the stopper body 11 is rotated clockwise in FIG. 3 so that the second side 12c becomes the frame through the state shown in FIG. 3 (b). The state shown in FIG. In this state, the first side 12a of the clamp lever 12 is oblique to the lower surface of the frame 21, and the substrate 11 of the stopper body 11 is
The gap S1 between the a frame 21 and the upper surface is smaller than the gap S3 before mounting, and when the keyboard is fixed, a sufficient frictional force is obtained and the keyboard is fixed on the frame 21.

Therefore, the position of the stopper body 11 is
As shown in FIG. 4, the front and rear surfaces of the keyboard 1 are fixed to each other by appropriately selecting them along the longitudinal direction of the keyboard.
Between the movable stopper 10 and the movable stopper 10 to prevent the displacement in the front-rear direction.

Also, the size of the keyboard has been changed and the stopper body
In order to move the first side 12a, the clamp lever 12 is rotated in the direction of arrow A from the state shown in FIG.
Is substantially parallel to the lower surface of the frame 21 as shown in FIG. In this state, there is no force to pull the stopper body 11 in the direction of the frame 21 other than its own gravity, so the elastic member 13 is restored to a substantially free thickness state, and the gap S3 between the substrate 11a and the upper surface of the frame 21 is maximized. , Can be easily slid on the frame 21.

Further, in order to remove the stopper body 11 from the frame 21, the clamp lever 12 may be lifted up in the state shown in FIG. 3 (c), and then pulled out to the left in the drawing. And the stopper body 11 can be lifted upward.

In the above-described embodiment, the case where the stopper according to the present invention is provided on the side that regulates the back position of the keyboard has been described. However, the stopper can be provided on the side that regulates the front position.

[Effect of the invention]

As described above, the stopper of the keyboard stand according to the present invention is placed so as to straddle the frame of the keyboard stand, and a stopper body having an elastic member adhered to a surface facing the frame, and a stopper on both sides of the stopper body. With a very simple structure including a clamp lever rotatably supported, the position can be freely moved according to the size of the keyboard.

Further, the stopper body can be fixed to and released from the frame with a single touch, and can be easily removed from the frame when the keyboard stand is stored or the stopper is unnecessary.
