[Embodiment of the invention]

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

The assembled music box mainly includes a base plate 11, a music box main body 12, a cover 13, and a stand 14 (FIGS. 1 and 2).

The base plate 11 is formed in a disk shape. An opening 11a and mounting holes 11b, 11b are formed in the base plate 11, a guide diagram 11c for positioning the music box body 12 is formed on the upper surface, and an outward engagement is formed on the outer periphery. A recess 11e is formed. The opening 11a is formed slightly eccentric with respect to the base plate 11. Further, hollow spacers 11d, 11d are erected on the base plate 11, and each spacer 11d is opened on the lower surface of the base plate 11 and has a mounting hole 11d1 formed on the upper end.

The music box main body 12 is configured by assembling a musical scale plate 12b, a drum 12c, a driving unit 12d including a mainspring, and a winding shaft 12e connected to the driving unit 12d, with respect to a base frame 12a. Screw holes 12a1, 12a1 corresponding to the mounting holes 11b, 11b of the base plate 11 are formed in the base frame 12a. Therefore, the music box body 12 can be placed on the base plate 11 in accordance with the guide diagram 11c so that the screw holes 12a1 and 12a1 correspond to the mounting holes 11b and 11b, and the hoisting shaft 12e can pass through the opening 11a. . Further, the music box body 12 can be screwed onto the base plate 11 by screwing set screws 12f, 12f into the screw holes 12a1, 12a1 from below the base plate 11 through the mounting holes 11b, 11b.

The cover 13 is formed in a dome shape with an open lower surface, and bosses 13 a, 13 a having a pilot hole 13 a 1 are vertically provided inside the upper surface. The lower end of the cover 13 bulges outward, and is formed with an inward step 13 b that fits the base plate 11. The step 13b is provided with an inward engagement projection 13c corresponding to the engagement recess 11e of the base plate 11 (FIG. 3). Also, decorative materials 13f, 13f... Of any shape can be adhered to the surface of the cover 13 at any positions (FIG. 1).

The cover 13 accommodates the base plate 11 in the step portion 13b, and engages the engaging projection 13c with the engaging concave portion 11e (FIGS. 2 and 3) to form the bosses 13a, 13b. a is positioned above the spacers 11d, 11d, and a wood screw or tapping screw type set screw 13d is screwed into the pilot hole 13a1 from below the base plate 11 through the mounting hole 11d1 of each spacer 11d. The music box main body 12 can be housed by screwing it to the box 11. The spacer 11d is capable of receiving the screw 13d, and the mounting hole 11d1 and the pilot hole 13a1 are formed to have a larger diameter and a smaller diameter, respectively, than the threaded portion of the screw 13d.

The stand 14 is formed in a disk shape (FIGS. 1 and 2), and has a support leg 14a erected at the center. The support leg 14a is formed with a screw hole 14a1 that fits the male screw portion 12e1 at the shaft end of the hoisting shaft 12e, and the male screw portion 12e1 has a smaller diameter than the hoisting shaft 12e. Then, the stand 14 can be screw-connected to the hoisting shaft 12e through the opening 11a by screwing the male screw portion 12e1 into the screw hole 14a1. Note that the stand 14 can stably support the entire base plate 11, the organ body 12, and the cover 13.

Such an assembled music box can be easily assembled by combining the music box main body 12, the cover 13, and optional decorative materials 13f, 13f. Prior to assembling, a music box body 12 for playing a desired melody, a cover 13d having a desired appearance, and decorative materials 13f having a desired shape are selected. In the assembled music box, the music box body 12 is screwed onto the base plate 11 via set screws 12f, 12f, the cover 13 is screwed onto the base plate 11 via set screws 13d, 13d, and the music box body 12 is wound up. The stand 14 can be screwed to the shaft 12e to assemble it into a finished product. The decorative materials 13f are fixed to the surface of the cover 13 by bonding them to arbitrary positions. However, the bonding of the decorative materials 13f, 13f... May be before or after the cover 13 is screwed to the base plate 11.

When the music box is assembled, the mainspring of the driving section 12 d of the music box main body 12 is wound up through the stand 14, and the music box is placed on a desk or the like via the stand 14. You can play. At this time, when the music box main body 12 is operated, the cover 13 rotates via the stand 14 while drawing a small circle corresponding to the eccentricity of the winding shaft 12e with respect to the base plate 11, and the decorative materials 13f, 13f. Can be turned.

In the above description, the cover 13 can be deformed into an arbitrary shape regardless of FIG. 1, and can be colored into an arbitrary color. However, the base plate 11 has a shape that can be combined with the cover 13. Further, the winding shaft 12 e of the music box body 12 may be located at the center of the base plate 11. Further, the base plate 11 and the cover 13 may have the engaging projection 13c formed on the base plate 11 side and the engaging concave portion 11e formed on the cover 13 side.

[0031]

[Effect of the invention]
