Benefits of technology

[0008]According to still another aspect of the present invention, the non-ferromagnetic spacer board is covered with a see-through hollow shell. The see-through hollow shell defines with the non-ferromagnetic spacer board an enclosed space that accommodates a free-flow substance. The at least one first magnet and the rotary member are provided inside the enclosed space within the see-through hollow shell. The at least one second magnet and the driving device are provided below the non-ferromagnetic spacer board outside the enclosed space. During rotation of the rotary member with the at least one first magnet, an axial flow (or eddy flow) is produced to move the free-flow substance in the enclosed space. This arrangement prevents leakage of the free-flow substance, and assures smooth rotation of the rotary member during operation of the driving device.
[0009]According to still another aspect of the present invention, the rotary member may be mounted with an ornament. The ornament can be the statue of a figure, animal, plant, landscape or famous landmark. Further, the free-flow substance can be water, oil, or very fine sand. When the driving device is started, the ornament is rotated with the rotary member, and the rotary member causes an axial flow (or eddy flow) to move the free-flow substance, showing a true sense of beauty.

Problems solved by technology

However, when either one of the two enclosed spaces is filled with a free-flow substance (water, oil, or very fine sand), the gasket may be unable to seal the gap between the axle and the partition, and the free-flow substance may leak from the enclosed space.
When a leakage occurs, rotation of the driven member may become unstable.

first embodiment

[0020]Referring to FIGS. 1˜5, a magnetic attraction type motion display toy in accordance with the present invention is shown comprising at least one set of magnets 11 and 12, a non-ferromagnetic spacer board 2, a rotary member 3 (that can be a fan blade or rotary table), and a driving source 4.

[0021]The magnets 11 and 12 are respectively arranged at the top and bottom sides relative to the non-ferromagnetic spacer board 2. The magnet 11 that is disposed at the top side of the spacer board 2 works as a passive member. The magnet 12 that is disposed at the bottom side of the spacer board 2 works as an active member. Further, the magnet 12 that is disposed at the bottom side of the spacer board 2 can be driven by the driving source 4. Further, the magnet 11 that is disposed at the top side of the non-ferromagnetic spacer board 2 is fastened to the bottom side of the rotary member 3 by means of an embedding or plugging technique, or with an adhesive.

[0022]The non-ferromagnetic spacer b...

second embodiment

[0037]Further, the ornament 7a of the aforesaid second embodiment is a simple ornament without flow passage. Alternatively, the ornament can be a rotating device or a device with light emitting means.

[0038]Further, a battery 51 is mounted inside the hollow base 5 to provide the motor 41 of the driving source 4 with the necessary working voltage. AC power adapter may be used to provide the necessary working voltage to the driving source 4.

third embodiment

[0039]FIG. 10 is a sectional view of a magnetic attraction type motion display toy in accordance with a According to this embodiment, the motor 41 of the driving source 4 is adapted for rotating the magnet 12 directly, and the ornament 7 has two flow passages 71.

[0040]Further, an axle bearing 94 is provided between the rotary member 3 or 3a and the pan 9 or 9a, and an axle 95 is supported in the axle bearing 94 and inserted through the pan 9 or 9a and connected between the ornament 7 or 7a and the rotary member 3 or 3a. The axle bearing 94 is isolated from the see-through hollow shell 6, assuring smooth rotation of the rotary member 3 or 3a and avoiding leakage. Further, the driven wheel 43 of the driving source 4 is provided with an axle bearing 431 and an axle 432, assuring smooth rotation of the driven wheel 43.

[0041]Further, the see-through hollow shell 6 is made of a transparent material and sealed to the hollow base 5 in a watertight manner. Sound and / or light generating mean...

Abstract

A magnetic attraction type motion display toy includes a base having a non-ferromagnetic spacer board at the top, a see-through hollow shell covering the base, a free-flow substance contained in the enclosed space defined by the see-through hollow shell and the base, a first magnet and a second magnet respectively provided at the top and bottom sides of the non-ferromagnetic spacer board for synchronous rotation by an external driving force by means of magnetic attraction, a rotary member fastened to the first magnet at the top and supporting an ornament, and a driving device mounted in the base for rotating the second magnet to cause synchronous rotation of the rotary member with the first magnet so that rotation of the rotary member causes the free-flow substance to flow in the enclosed space.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to motion display toys and more particularly, to a magnetic attraction type motion display toy that utilizes a magnetic attractive force to cause rotation of a rotary member, forcing a free-flow substance to flow in an enclosed space.[0003](b) Description of the Prior Art[0004]A conventional rotation mechanism generally comprises drive member and a driven member. The driven member is directly connected to the drive member for direct rotation by the drive member. When the driven member and the drive member of a rotation mechanism are respectively set in two enclosed spaces, an axle must be used and inserted through a hole on the partition between the two enclosed spaces to connect the driven member to the drive member. To prevent leakage, a gasket may be used to seal the hole of the partition. However, when either one of the two enclosed spaces is filled with a free-flow substance (water, o...
