Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic musical instrument whose head and body are separable, and particularly to an electronic musical instrument whose assembly work can be easily and safely performed.

A conventional electronic musical instrument, as shown in FIG.
A body part 7 having a speaker 5 and a foot keyboard 6 is integrally constructed. This results in a very large volume when packaged, which has the drawback of significantly increasing transportation costs.

In order to solve this problem, as shown in FIG. 2, the head 4 and body 7 are configured to be separable,
During transportation, there is one in which the head 4 is stored in front of the body 7, as shown by the broken line in FIG. In this way, it is possible to pack the product in dimension A, which is smaller by the thickness of the head 4.

However, even in this case, the only dimension that can be reduced is the thickness of the head 4, so the volume at the time of packaging does not become so small.

In order to solve these problems, the inventor developed an electronic musical instrument as shown in Figs.
- Proposed as No. 165292.

To explain this, in Figures 3 to 6,
8 is a head, 9 is a side plate thereof, 9a is an extension of the rear end of the side plate 9 extending downward, 10 is a trunk, 11 is a side plate, and 12 is a leg provided at the lower end. The extension part 9a of the side plate 9 of the head part 8 and the side plate 11 of the body part 10 are overlapped by a predetermined amount, and a coupling member 13 rotatably connects the head part 8 and the body part 10 to this overlapped part. is provided, and a head 8 is provided.
Fixing means 1 for fixing to the position indicated by the solid line in Figure 3
4 are provided.

4a and 4b show the specific structure of the fixing means 14. An angle 15 is attached to the inside of the side plate 11 of the body 10, and a fixing pin 17 is attached to this angle 15 via a spring 16. The tip of the pin 17 is passed through the through hole 11a provided in the side plate 11 of the body plate 10, and
A hole 9b is provided at an appropriate position in a. In this way, when the head 8 is not in use with the head 8 tilted forward, the tip of the fixing pin 17 is lightly pressed against the inner surface of the side plate 9a, as shown in FIG. When lifted and rotated by a predetermined angle, the hole 9b moves to a position facing the fixing pin 17, and the fixing pin 17 is automatically inserted into the hole 9b by the biasing force of the spring 16, as shown in FIG. 4b. inserted. Therefore, assembly work can be easily performed by one person.

By the way, in the case of the above-mentioned structure, a force is applied to the head 8 in the direction of forward rotation, and an unreasonable force is applied to the fixing means 14, or the head 8 is accidentally rotated during assembly work. There is a risk of it falling. In order to solve this problem, a fall prevention plate 18 may be installed between the lower end of the side plate 9 of the head 8 and the upper end of the legs 12, as shown in FIG. In this way, it is possible to prevent problems such as excessive force being applied to the fixing means 14 or the head 8 falling down during assembly.Moreover, the depth of the fall prevention plate 18 can be set to the same thickness as the side plate 9 of the head 8. If this is done, there will be no difference in level between the side plates 9 and 11, so the appearance can be made beautiful.

Furthermore, as shown in FIG. 6, the thickness of the portion 9b of the side plate 9 of the head that overlaps with the side plate 11 of the body 10 is made thinner, and the center of the fall prevention plate 19 is made thinner.
If the fall prevention plate 19 covers all of the front and rear ends and side surfaces of the side plate 11, including the thin portion 9c, the connector 13 will also be hidden, resulting in an even better appearance.

By the way, if such fall-prevention plates 18 and 19 are simply placed along the side plates 11 of the body 10, the head 8 and body 10 may not be easily moved when transported together at an exhibition hall or at home, for example. When the part 8 moves slightly upward and the distance between the lower end of the side plate 9 and the upper end of the leg 12 becomes longer than the length of the fall prevention plates 18 and 19 in the vertical direction, the fall prevention plates 18 and 19 will easily come off. There are problems such as damage to the outer surface when the product is stored away or dropped. To solve this problem, the fall prevention plate 18,
19 to the side plate 11 with screws or nails, it becomes very difficult to assemble and disassemble the product when displaying it as a completed product at a store, etc., when repacking it and sending it to the buyer, or when moving. becomes difficult.

The present invention is designed to solve such problems, and one embodiment thereof is shown in FIGS. 7 and 8 below.
This will be explained with figures.

7 and 8 show the side plate 11 and the fall prevention plate 19.
At the four corners of the mounting tape, as shown in FIGS. 8a and 8b, the surface has a large number of locking rings 20a and a large number of "i"-shaped locking pieces 21a that are locked to these locking rings. 20 and 21 respectively, and by pressing the fall prevention plate 19 toward the side plate 11, the locking piece 21a is locked to the locking ring 20a, and the fall prevention plate 19 is attached to the side plate 11. be. Here the mounting tape 20, 21
If the locking ring 20a and the locking piece 21a are made of a flexible resin material, etc., when the fall prevention plate 19 is pulled away from the side plate 11, the bent part at the tip of the locking piece 21a will extend and be installed. Since the tapes 20 and 21 are easily peeled off, the fall prevention plate 19 can be attached and detached very easily and can be attached and detached any number of times. The shapes of the locking rings 20a and locking pieces 21a of the mounting tapes 20 and 21 are not limited to those shown in FIG. 8, but may be of any shape as long as they perform substantially the same function. A commercially available product under the trade name (Trademark) can be used.

9 and 10 show a second embodiment of the present invention, in which recesses 11a are provided at the four corners of the side plate 11, and a fixture 22 having large leg portions 22a at the tips is screwed into the recesses 11a. At the four corners of the fall prevention plate 19,
A cap 23 made of rubber, resin, etc. having a concave portion 23a with a narrowed tip is attached using screws 24, and by pressing the fall prevention plate 19 toward the side plate 11, the concave portion 23a of the cap 23 is fixed to the fixing device, 2.
It is designed to fit on the tip of 2. In other words, a type of hook is used to prevent the plate from falling 19
The side plate 11 is detachably attached to the side plate 11. Even in this case, effects similar to those of the embodiments shown in FIGS. 7 and 8 can be obtained.

In addition, in FIGS. 7 and 9, the mounting tape 21 and the cap 23 are attached to the protruding parts on both sides of the inner surface of the fall prevention plate 19, and these are pressed against the surface of the side plate 11, but as explained in FIG. When covering the front and rear ends of the side plate 11 with the protrusions on both sides of the fall prevention plate 19 as shown in FIG.
may be provided in the recessed portion of the inner surface of the fall prevention plate 19.
Further, the present invention can be similarly applied to the case where a flat plate-shaped fall prevention plate 18 is used as shown in FIG.

As described above, the present invention provides an electronic musical instrument in which the head and the body are separated, such that the legs are arranged between the lower end of the side plate of the head and the upper end of the leg provided on the body so as to fall along the side plate of the body. By attaching the prevention plate, the work of assembling the head and body is facilitated, and the fall prevention plate can be attached and detached from the side plate of the body using easily attachable and detachable attachment means such as hooks and mounting tape. Since the plate is designed to be attached, the fall prevention plate can be stably attached with a simple assembly process, and the plate can be easily disassembled when moving or the like, which is an excellent effect.
