Description

[Detailed Description of the Invention] The present invention relates to an upright combo electric piano.

This type of electric piano is required to be small, lightweight, low cost, and easy to transport, but conventional ones have a stringing frame, keyboard, and action fixed to the case. must be robust, which not only makes it impossible to make it lightweight, but also makes it large and expensive, and is difficult to transport.In order to solve this problem, the inventor of the present invention We have proposed an electric piano in which a stringing frame is directly supported by the legs, a keyboard and an action are supported on the stringing frame, and a case is attached to make the case smaller and lighter.

The present invention relates to an improvement of this electric piano, and its purpose is to mechanically protect the stringing frame, the keyboard, and the case that houses the action with the legs when the legs are removed from the stringing frame for transportation. It has a keyboard, an action, a stringing frame, a case, and legs, the legs being larger than the width and height of the side surface of the case, and the action being attached to the stringing frame and allowing the keyboard to rise and fall freely. The case accommodates a stringing frame, an action, and a keyboard placed face down on the stringing frame, and the legs can be attached to both sides of the stringing frame through the sides of the case, and when set, The stringing frame is fixed to the stringing frame so as to be lifted off the floor and supported, and when transported, the stringing frame is lowered to the floor and is stacked on both sides of the case to serve as a protector for the case. It is characterized by being fixed to the string frame.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows a stringing frame 1 for an electric piano according to the present invention, in which protrusions 2 at least approximately equal to the thickness of the case, which will be described later, are formed on the upper, middle, and lower stages of both sides of the frame 1 for stringing the electric piano. Protrusions 3 and 4 for mounting an action and a protrusion 5 for attaching a keyboard butterfly are formed on the front surface of the side.

FIG. 5A shows a case body 6a housing the stringing frame 1, and a case lid 6 housing the action.
6 shows a case 6 consisting of a case lid 6c and a case lid 6c that accommodates a keyboard. The case body 6a is a stringed frame 1
has a notch 7 that exposes the upper, middle, and lower protrusions 2 on both sides, the upper edge is connected to the case lid 6b via a hinge 8, and the lower edge is connected to the case lid 6b via the hinge 8. I made it connect to 6c. FIG. 5B shows the rear legs 9 supporting the stringing frame 1;
In order to fix this rear leg 9 to the stringing frame 1, holes 10 for bolts to be screwed into the screw holes of the upper, middle, and lower protrusions 2 of the stringing frame 1 are formed in each of the lower parts. Front legs 12A, 12 shown in FIG. 5C, D
A hole 11 for connection with B was provided. This hind leg 9
The width and height of case 6 were made larger than those of case 6, respectively.

The front legs 12A and 12B have substantially the same shape, but are different in that the lower end of one front leg 12A is a tubular body, and the lower end of the other front leg 12B is a rod-shaped body that fits into the tubular body. .

Thus, when putting the electric piano of the present invention into the set state, the upper and center holes 10 of the rear legs 9 shown in FIG. 5B are inserted into the screws of the middle and lower projections 2 of the stringing frame 1 shown in FIG. 5A. This hole 10 according to the hole
By screwing bolts into the stringing frame 1, the stringing frame 1 is raised and supported from the floor as shown in the second figure. Open the case lid 6c downward and attach the stringing frame 1.
After raising the keyboard 14, which is screwed onto the keyboard and hanging down, to a nearly horizontal position as shown in the first figure, close the case lid 6c and insert the front legs 12A and 12B into the lower part. 9 using the holes 13 and 11, and is also fixed to the keyboard 14 by means not shown. Since the front legs 12A, 12B are fixed to the rear legs 9 at a height that maintains the keyboard 14 in a horizontal state, even if the floor surface on which the front legs 12A, 12B are located is uneven, or if the keyboard 14 is hit hard, the keyboard 14 will not move. The action 15 can always be kept at a right angle, and there is no risk of impairing the function of the action.

When transporting this electric piano, the front legs 12A and 12B are removed from the rear legs 9 and the keyboard 14, the case lid 6c is opened, the keyboard 14 is allowed to hang down, and the case lid 6c is closed. Next, the case 6 is laid down, the bolts are removed, and both rear legs 9 are placed on both sides of the case 6. In this state, the upper, middle, and lower holes 1 of the hind legs 9
0 coincides with the holes of the protrusions 2 of the stringing frame 1 exposed from the upper, middle, and lower notches 7 of the case 6, so
A bolt is screwed into each hole to fix the rear leg 9 to the stringing frame 1. Next, the rod-shaped portion at the lower end of one front leg 12B is fitted into the tubular portion at the lower end of the other front leg 12A to integrate them. At this time, the entire length of the front legs 12A, 12B is set to be equal to the width of the case 6, so the front legs 12A, 12B are set to be equal to the width of the case 6.
B is fitted between the rear legs 9, 9 fixed to the stringing frame 1, and screwed thereto. Thus case 6
is mechanically protected by front legs 12A, 12B and rear legs 9, 9.

As described above, according to the present invention, the legs that are raised above the floor and directly support the stringing frame are larger than the width and height of the case, and can be attached so as to overlap the sides of the stringing frame. When the mounting position of the legs on the stringing frame is changed for transportation, etc., the legs act as a protector to protect the stringing frame, the keyboard, and the case that houses the action. Even if it is physically weak, it will not be destroyed during transportation, and it is convenient to transport and easy to assemble.
