DEVISE FOR CONNECTING PLURAL MULTI-SHAPED BODIES UTILIZING MAGNETS
Document Type and Number:
Kind Code:
A1

Abstract:
The devise described herein relates to connecting plural multi-shaped non metallic bodies utilizing disc shaped permanent magnets. The invention consists of disc magnets with axial orientation. The disc magnets are adhered within the center of a plastic bearing. The shape of the plastic bearing consists of a spherical segment relative to the height of the disc magnet creating a pivot point in the center of the disc magnet. Magnet and bearing combinations are placed into the spherical segment cavities reset into the plural bodies. When plural bodies containing the magnet bearing combination are placed close enough to over lap the flux field of each magnet the reaction will be instantaneous rotation of the opposing magnets to there position of attraction and subsequently connecting the bodies together.

Claims:

What I claim as my invention is:



1. A device for connecting multi-shaped plural bodies utilizing magnets composed of: Two non-metallic sub-bodies having equal spherical segment cavities. A disc magnet with axial orientation. A non-metallic convex bearing with a spherical segment diameter that is less than the spherical segment cavity diameter of said sub-body. Said disc magnet is affixed within the center of said bearing establishing the pivot point in the center of said magnet which is seated between said sub-bodies enabling 360 degree rotation of said magnet bearing combination between said sub-bodies.

2. Plural four sided pyramid shaped main bodies containing and utilizing the device of claim 1 on all flat side surfaces.

3. Plural five sided pyramid shaped main bodies containing and utilizing the device of claim 1 on all flat side surfaces.

4. Plural six sided cube shaped main bodies containing and utilizing the device of claim 1 on all flat side surfaces.

Description:

BACKGROUND OF INVENTION

[0001] The present invention relates to connecting plural multi-shaped bodies utilizing permanent magnets contained within there bodies. More specifically the present invention devise achieves the connection of plural multi-shaped plastic bodies with magnets to each other with no regard to the polarity of opposing plural magnets.

[0002] Plastic bodies with magnets contained within there bodies are not new. U.S. Pat. No. 5,746,638 issued to Shiraishi describes one such design using magnets for connecting bodies, however the design has several disadvantages. First, the wall surface between attached magnets reduces the strength of the connection. Secondly the surface used in Shiraishi's design for the magnet to rotate on produces excessive resistance for instantaneous rotation of opposing magnets.

[0003] U.S. Pat. No. 5,347,253 issued to Ogikubo describes another design for attracting plural bodies with similar disadvantages. The necessity to incorporate a wall surface between opposing magnets lowering the strength of the connection between plural bodies utilizing magnets. The next disadvantage of Ogikubo's design is the shape of the magnet, which is a complete sphere. When plural sphere shaped magnets are connected, the point of contact between the surfaces of the magnets is small fraction of the magnet surfaces, lowering the strength of the connection between plural bodies utilizing magnets.

SUMMARY OF INVENTION

[0004] This invention provides a devise to align the poles of permanent magnets contained within plural bodies to there position of attraction securing the connection of plural bodies. This is accomplished thru the use of the magnet bearing combination that is seated within bearing cavities in the bodies and retained in this position using the bearing cap. This invention allows plural bodies with magnets reset into the surfaces of the bodies to be connected in any positional relation with no regard to the polarity of the magnets.

[0005] It is the object of the present invention to solve previous disadvantages thru the present invention devise which utilizes the maximum strength of permanent magnets and creates the least resistance from opposing magnets during there rotation to there attraction position for connecting plural bodies. It is yet another object of the present invention to utilize the present devise in all plural bodies having mutual attraction requirements such as toy blocks, puzzle pieces and construction sets but not limited to these few applications.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The preferred embodiments will now be described. FIG. 1 the four sided pyramid main body according to the first embodiment of the present invention. Referring to the designated at 1 is a main body made of injection molded plastic resin. Designated at 1 a and 2 a sub bodies having equal spherical segments. Designated at 2 is a injection molded plastic resin retaining cap. Designated at 3 is a disc shaped permanent magnet with axial orientation of its poles. Designated at 4 is a bearing made of injection molded plastic resin. The disc magnet 3 is affixed to the inside diameter of bearing 4 . Magnet 3 and bearing 4 combinations are seated between the cavities of the sub bodies 1 a and 2 a . Magnet 3 , bearing 4 and sub-bodies 1 a and 2 a are adhered to the main body 1 .

[0013] FIG. 2 the five sided pyramid main body according to the second embodiment of the present invention. Referring to the designated at 1 is a main body made of injection molded plastic resin. Designated at 1 a and 2 a are sub bodies having equal spherical segments within there inside diameter. Designated at 2 is a injection molded plastic resin retaining cap. Designated at 3 is a disc shaped permanent magnet with axial orientation of its poles. Designated at 4 is a bearing made of injection molded plastic resin. The disc magnet 3 is affixed to the inside diameter of bearing 4 . Magnet 3 and bearing 4 combinations are seated between the cavities of the sub bodies 1 a and 2 a . Magnet 3 , bearing 4 and sub-bodies 1 a and 2 a are adhered to the main body 1 .

[0014] FIG. 3 the six sided cube main body according to the third embodiment of the present invention. Referring to the designated at 1 is a main body made of injection molded plastic resin. Designated at 1 a and 2 a sub bodies having equal spherical segments. Designated at 2 is a injection molded plastic resin retaining cap. Designated at 3 is a disc shaped permanent magnet with axial orientation of its poles. Designated at 4 is a bearing made of injection molded plastic resin. The disc magnet 3 is affixed to the inside diameter of bearing 4 . Magnet 3 and bearing 4 combinations are seated between the cavities of the sub bodies 1 a and 2 a . Magnet 3 , bearing 4 and sub-bodies 1 a and 2 a are adhered to the main body 1 .

[0015] FIG. 4 a is cross section of a surface from the six sided cube main body according to the third embodiment of the present invention. FIG. 5 is a fragmented cross-sectional view of two six sided cube main bodies according to the third embodiment of the present invention. When plural bodies are brought close enough together as to overlap the magnetic flux field of the magnets contained within their bodies the reaction of magnet 3 and bearing 4 will be to rotate to there position of mutual attraction as shown in FIG. 5 .

[0016] From the forgoing description one can now see how multi-shaped plural bodies are connected utilizing magnets contained within their bodies without the need of matching individual polarities. The attracting bodies can now be used to create a multitude of geometric shapes. Further it has been shown how this invention has improved upon previous inventions through the device which allows a magnet to magnet connection exploiting the maximum strength of magnet 3 and the bearing 4 surface configuration which minimizes rotation resistance.
