Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a swinging ornament.

[Prior Art] Conventionally, there are decorations that utilize the swinging motion of a clock pendulum, for example. As an example,
Publication No. 31901 discloses a pendulum configured as a rotating ornament. This is because the drive body that constitutes the Tenfu mechanism is fixed to the drive shaft, and this drive shaft movably penetrates the elongated hole made in the opposite substrate of the support body, and the end protruding from the substrate. A gear-shaped rotating decorative member is fixed. The support body is provided with a detection drive coil that rotationally drives the heaven mechanism. For this reason, when the Tenfu mechanism is rotated by the magnetic repulsion of the detection drive coil,
As the drive shaft rotates, it rolls inside the elongated hole and moves back and forth, creating a decoration that gives the illusion that the gears are rotating and moving back and forth.

[Problems to be Solved] According to the conventional example described above, the configuration is complicated because the Tenfu mechanism is used. In addition, the permanent magnet is fixed in place on the drive body and moves as the drive body rotates, so in order to apply magnetic repulsion to the permanent magnet at the optimal position, it is necessary to supply the magnetic repulsion force to the detection drive coil. The timing of the drive signals used is extremely difficult.

An object of the present invention is to provide a swinging ornament that has a simple structure, makes it easy to apply magnetic driving force to the permanent magnet at an optimal position, and continues stable swinging motion.

Another object of the present invention is to add to the above-mentioned swinging decoration an ornament that moves together with the swinging decoration itself, thereby increasing the interest.

Still another object of the present invention is to make the patterns that appear on the swinging ornaments variable, thereby further demonstrating its characteristics as an ornament.

[Means for Solving the Problems] In order to achieve the above object, the swinging decoration of the present invention includes a decoration body and a support body that supports the decoration body in a rollable manner. And the decoration is
A cylindrical body, side plates provided at both end openings of the cylindrical body, and a permanent magnet that is always held in a hanging state via a holding member from a central shaft whose both ends are supported by the side plates. Equipped with: The support body also includes a drive coil that can face the permanent magnet, and an arc-shaped guide rail on which the cylinder can roll and move freely due to the electromagnetic driving force of the drive coil and the permanent magnet. Equipped with

To add more interest, the cylindrical body is provided with an opening, and a decoration that protrudes outward from this opening is provided integrally with the holding member.

Furthermore, in order to make the decoration more varied, the central shaft is rotatably supported relative to the side plates, and a decorative plate is fixed to the central shaft at a position facing at least one of the side plates. A moving pattern is created by the overlap of the pattern on the plate and the pattern on the plaque.

[Example] An example of the present invention will be described based on the drawings.

FIGS. 1 and 2 show a first embodiment of the present invention, and the swinging decoration consists of a decoration body 1 and a support body 2. First, the ornament 1 will be explained. A cylindrical body 11 of the decorative body 1 is provided with side plates 12 and 13 facing each other so as to close openings at both ends thereof. A central shaft 14 located along the axis of the cylindrical body 11 is supported by both side plates 12 and 13 with both ends of the shaft fixedly attached. A holding member 1 is attached to the central axis 14.
A ring-shaped holding portion 15a provided at the upper end of the holder 5 is rotatably fitted therein. A permanent magnet 16 is fixed to the lower end of the holding member 15, and the permanent magnet 16 is held in a hanging state at all times even when the central shaft 14 rotates. Ring-shaped protrusions 11a are provided at both ends of the cylindrical body 11.

Next, the support body 2 will be explained. A mounting shaft 21a for mounting a coil is erected on the bottom plate 21 of the support body 2 at a position slightly offset to one side from the center thereof, and a drive coil 22 is mounted on this mounting shaft 21a. Guide rails 23 and 24 are erected from the bottom plate 21 in parallel at a predetermined interval so as to contact the outer circumferential surface of the cylindrical body 11.
a, 11a are both guide rails 2 as shown in the second diagram.
3 and 24 to prevent the cylindrical body 11 from coming off the rail. The guide rails 23 and 24 have a concave arc shape from the front, and the cylindrical body 11 can freely reciprocate by rolling on the rails. During this movement, the permanent magnet 16 can face the drive coil 22, and the drive coil 22 and the permanent magnet 16 constitute an electromagnetic drive device.

With such a configuration, when the decoration 1 is placed on the support 2 as shown in the first figure, the decoration 1 rolls on the cylindrical body 11 and moves onto the arc-shaped guide rail 2.
It stabilizes at the lowest point of 3.24. At this stable point,
The center of the drive coil 22 is slightly offset from directly below the permanent magnet 16. Therefore, when a drive signal is supplied to the drive coil 22 and it becomes an electromagnet, the permanent magnet 16
receives a driving force to the left in FIG. 1 due to the magnetic repulsion between it and the electromagnet. Although the permanent magnet 16 swings momentarily when this magnetic repulsion is applied, it is held in a hanging state because the space between the holding portion 15a and the central shaft 14 is rotatable. The decoration body 1 moves to the left as the cylinder body 11 rolls on the guide rails 23 and 24 in response to this driving force. The decorative body 1 moves up the arc-shaped rail and stops when the influence of driving force and inertia disappears,
The next drive signal is sent to the drive coil 2 at the moment when it reverses direction and descends on the rail toward the lowest point, then rolls due to inertia and passes over the drive coil 22.
2. For this reason, the decoration body 1 receives a driving force to the right this time, and moves to the right in the same way, and this is repeated to continue the stable movement of the swinging decoration.

By forming desired figures, patterns, etc. on the outer surfaces of the side plates 12, 13, you can not only enjoy rolling and moving, but also enjoy the changes in the figures.

FIG. 3 shows a second embodiment, in which the decorative body 3 has an opening 31b having a predetermined length in the circumferential direction at the upper part of the cylindrical body 31. A decoration 37 such as a doll is projected from the opening 31b to the outside, and the inner end of the decoration 37 is connected to the holding part 35a of the holding member 35, so that the decoration 3
7. The holding member 35 and the permanent magnet 36 are integrally provided. Note that the side plate, central shaft 34, and holding member 3
5. The structure of the permanent magnet 36 is the same as that of the first embodiment, and the structure of the support body is also the same as that of the first embodiment, although it is not shown.

In the second embodiment having such a structure, when a driving force is applied to move the decorative body 3 in the same manner as in the first embodiment, when a magnetic repulsion force acts on the permanent magnet 36, the permanent magnet 36 is moved. As the magnet 36 momentarily swings, the decoration 37 also swings, so the decoration 3
When moving, the decoration body 3 moves left and right while the decoration 37 swings left and right, resulting in a fun swinging decoration.

The length of the opening 31b is appropriately set in consideration of the movement of the ornament 3.

4 and 5 show a third embodiment, in which the decorative body 4 has a side plate 4 fixed to a cylindrical body 41.
A central shaft 44 is rotatably supported with respect to 2 and 43, and a holding member 45 and a permanent magnet 46 are attached to the central shaft 44.
is fixed. Also, the side plate 4 is attached to the central axis 44.
A decorative plate 47 is fixed in a non-rotatable manner at a position facing 3. The side plate 43 is made of a transparent plate, and has a pattern 43a formed of parallel lines at predetermined intervals on its inner or outer surface. Also, the plaque 47
A pattern 47a is formed by parallel lines in the vertical direction. Such a decorative body 4 is placed on guide rails 23, 24 of a support body 2 similar to those described above.

In the third embodiment configured in this way,
When the decorative body 4 reciprocates while rotating on the guide rails 23 and 24 by the same action as in the above-described embodiment, the side plate 43 rotates together with the cylinder 41, so that the pattern 43a thereof rotates. On the contrary,
Since the permanent magnet 46 is maintained in a suspended state in the direction of gravity, the central shaft 44 does not rotate, the decorative plate 47 does not rotate, and the pattern 47a thereof does not rotate. For this purpose, a rotating pattern 43a and a stationary pattern 47
A appears to overlap as the angle changes, creating a moiré pattern that moves as the angle changes moment by moment.
Moreover, this movement is a reciprocating movement in which the direction of rotation is reversed, and the rotation speed is slower at both ends, so the pattern changes are not monotonous changes, but rather complex and interesting decorations.

Note that a decorative plate may be further provided at a position facing the other side plate 42. Moreover, instead of generating a moiré pattern, the pattern on the side plate is made into a watermark pattern, the pattern is formed on the decorative plate, and as the side plate is rotated, the internal pattern appears and disappears from the watermark, creating an interesting moving pattern.

[Effect] The swinging ornament of the present invention with the above structure has a simple structure, and is capable of applying a magnetic driving force at an optimal position to a permanent magnet suspended in the direction of gravity. It is extremely easy to energize the drive coil, and stable rocking motion can be continued.

Furthermore, by adding decorations that move together while subtly oscillating themselves, it is possible to further increase the interest.

Furthermore, by overlapping the patterns on the side plate and the decorative plate, a moving pattern is created, creating a swinging decoration with a rich variety of variations, which further enhances the characteristics of the decoration.
