Description
- This application is a continuation of provisional U.S. application 60/960,439 filed Sep. 28, 2007 having the same inventor.
- The invention has particular application to methods and apparatus for entertainment and more specifically to toys.
- The prior art includes a wide variety of toys including children's tops that are caused to rotate by a vertical shaft, having a helical exterior surface, that is pushed into a meshing bore in a generally cone shape body to cause the cone shape body to rotate.
- Wikipedia reports:
-
- “A top, or spinning top, is a toy that can be spun on an axis, balancing on a point. The top is one of the oldest recognizable toys found on archaeological sites. Besides toys, tops have also historically been used for gambling and prophecy. Some role-playing gamers still use tops to augment dice in generating randomized results, it is in this case referred to as a Spinner. A thumbtack may also be made to spin on the same principles.
- The action of a top relies on the gyroscopic effect for its operation. Typically the top will at first wobble until the shape of the tip and its interaction with the surface force it upright. After spinning upright for an extended period, the angular momentum, and therefore the gyroscopic effect, will gradually lessen, leading to ever increasing precession, finally causing the top to topple in a frequently violent last thrash.
- In recent years there have been many developments with the technology of the top. Bearing tops, with a tip that spins, have been one of the biggest changes. Fixed tip tops and bearing tops are featured in National Championships in Chico, Calif. and in the World Championships in Orlando, Fla.”
- It is an object of the present invention to provide a novelty apparatus that will entertain, educate and arouse the curiosity of young and old.
- Another object of the invention is to provide apparatus that is simple in construction as well as assembly.
- A further object of the invention is to provide apparatus that can be manufactured inexpensively it has now been found that these and other objects of the present invention may be attained in a novelty apparatus which includes SPa rotationally symmetrical hollow body having an axis; a shaft having an axis and first and second axial extremities, the axis of the shaft being disposed in the rotationally symmetrical hollow body with the axis thereof disposed substantially coincident with the axis of the rotationally symmetrical body; first and second bearings disposed at axially spaced portions of the shaft and supporting the shaft for rotational movement about the axis thereof; a disc fixed to the shaft; and a motor for driving the shaft.
- Some forms of the novelty apparatus include a switch and battery for connection in series to the motor. Some forms include a housing having first and second discrete sections that are dimensioned and configured to be selectively coupled together to permit selective access to the interior of the housing for installation of a battery. The selectively coupled housing sections may include mating lips. The mating lips may include a lip on the first section overlapping a lip on the second section for selectively coupling the sections together to permit selective access to the interior of the housing for installation of a battery.
- The disk may be fixed to the shaft at a point closer to the axial extremity of the shaft that is lowest during normal operation of the apparatus. Similarly, the motor may be attached to the shaft at a point closer to the axial extremity of the shaft that is lowest during normal operation of the apparatus. In addition, the battery may be disposed closer to the axial extremity of the shaft that is lowest during normal operation of the apparatus than to the axial extremity of the shaft that is highest during normal operation of the apparatus.
- The invention will be better understood by reference to the accompanying drawing in which:
-
FIG. 1 is a schematic side view of a preferred form of the present invention having an exterior housing having a cross section which is substantially elliptical. -
FIG. 2 is a schematic side view of another form of the exterior housing having a cross section which is substantially spherical and which illustrates schematically an embodiment having to discrete hemispheres and further illustrates schematically various interfaces coupling the concave faces of the respective discrete hemispheres in opposed relationship. -
FIG. 3 is a schematic diagram illustrating the wiring connecting a switch, and a battery and a motor in a preferred form of the invention. - Referring now to
FIG. 1 there is shown anovelty toy assembly 10 in accordance with one form of the present invention. In this embodiment the exterior housing 12 has a cross section that is generally elliptical. Other forms of the present invention have an exterior housing 12 that is substantially spherical and thus will have an exterior housing that has a cross section that is substantially a circle. Embodiments of the present invention are particularly suited for use on the top surface of a table or alternatively floating in water such as the water in a bathtub. Accordingly, a spherical (or similar shape) outer housing will have a substantially point contact between the planar surface of a table. Thus, the utilization of a spherical or similar shape facilitates rotation of the outer housing about this point contact. - Similarly, the rotation of the outer housing 12 while floating in water is best achieved by avoiding turbulence in the body of water. Turbulence is minimized by the use of spherical or similar shapes as well as any shape that is rotationally symmetrical. Those skilled in the art will recognize that a cube, for example, would create substantial turbulence if rotated about any axis thereof in water.
- A
disk 14, ordinarily disposed in operation in substantially horizontal orientation (with the axis thereof disposed in substantially vertical orientation) is fixed to ashaft 16 having an axis that is ordinarily disposed in operation in substantially vertical orientation. In some embodiments thedisk 14 will be fixed to theshaft 16 below the midpoint thereof. Ordinarily, location of thedisk 14 near the midpoint of theshaft 16 will permit the use of a larger diameter disk 14 (because of the geometry of the housing 12) and this will increase the stability of theoperating toy 10. - The
shaft 16 is supported as the lower extremity (in normal operation thereof) by a combination bearing, motor andbattery assembly 18. The bearing portion of this assembly supports theshaft 16 with a journal bearing in a preferred embodiment of the invention. Themotor 19 portion of thisassembly 18 is coupled to theshaft 16 to rotate theshaft 16 and thereby thedisk 14. Themotor 19 portion receives power from thebattery 21 portion of theassembly 18. A preferred embodiment of invention utilizes abattery portion 21 that included two AA batteries. Ordinarily, typical direct current motors that operate from batteries operate at a much higher speed of rotation than is preferred for rotation of thedisk 14. Thus, preferred embodiments utilize a gear train, in a manner well known by those skilled in the art, to reduce the rotational speed of theshaft 16 and thus thedisk 14. - The upper axial extremity of the shaft 16 (in normal operation as well as viewed in the drawing) is supported by a
bearing 20 that is a journal bearing in the preferred embodiment. Disposed proximate to thebearing 20 is aswitch 22. Theswitch 22 is a single pole, 2 position push: the switch in a preferred embodiment. The position of theswitch 22 at the top of theassembly 10 enables and facilitates operation of theswitch 22 when theassembly 10 is in operation and its desired to stop the operation as well as up when the assembly is off and is desired to start the operation of theassembly 10. - To facilitate replacement of the batteries in the
battery portion 21 various embodiments of the present invention will provide access to the interior of the outer housing 12. A preferred embodiment illustrated schematically inFIG. 2 utilizes an outer housing comprising afirst hemisphere 24 and asecond hemisphere 26. As shown in the drawing thefirst hemisphere 24 overlaps thesecond hemisphere 26 at the equator of the assembly of thefirst hemisphere 24 and thesecond hemisphere 26. The interface between thefirst hemisphere 24 and thesecond hemisphere 26 is shown schematically identified by thenumeral 28. It will be understood that the interface will ordinarily extend 3600 around the equator of this assembly. - Various embodiments will utilize an
interface 28 that includes frictional engagement, mating lips, male and female threads in other joining structure between thehemispheres interface 28 between thehemispheres apparatus 10 is intended for utilization in water in at least some cases. Still other embodiments of the present invention may utilize other battery mountings. For example, a preferred mountings that would position the battery to maintain the center of mass of theassembly 10 coincident with theshaft 16 and still avoid entry of water into the housing 12. - Preferably, the center of mass of the
entire assembly 10 will not only be coincident with theshaft 16, it should also be nearer to the bottom of theassembly 10 than to the top of theassembly 10 to maximize stability. The mounting for the battery (holding the battery) may, for example, be a module that screws in to the bottom of theassembly 10. Such an assembly would eliminate the need for the seal at the equator of the apparatus. - Some embodiments of the present invention provide a framework within the housing 12 to support the
bearing 20, the bearing portion of the combination bearing, motor andbattery assembly 18. (that collectively support theshaft 16 and disc 14), themotor 19, and thebattery 21. One such framework provides a first circular hoop fixed to the interior of the housing (not shown) in a first plane in addition to a second circular hoop fixed to the interior of the housing (not shown) in a second plane that is perpendicular to the first plane. An advantage of such embodiments is that the housing 12 may be fabricated of thinner material than embodiments that do not include this framework. - Ordinarily, the housing will be manufactured from transparent plastic material. Similarly, the
shaft 16 and thedisc 14 will also be plastic, however they will ordinarily be opaque. - In operation the user places the
assembly 10 on a planar surface such as a tabletop or into a pool of water such as a bathtub full of water, depresses the push buttons switch 22 which causes the contacts thereof to connect power from thebattery 21 to themotor 19. Themotor 19 then drives theshaft 16 causing the attacheddisk 14 to rotate. This in turn causes the entire assembly to then rotate in the same direction as the direction of rotation of thedisk 14. A phenomenon not fully understood is that when thereafter theswitch 22 is operated to stop power from thebattery 21 to themotor 19 the assembly will spontaneously and consistently begin to counter rotate. The counter rotation occurs as if a spring were being wound up during movement of thedisk 14 by themotor 19. However, the apparatus has no such spring and there is no present an explanation for this phenomenon. - It will thus be seen that the described apparatus will provide much entertainment and education as well as stimulation of the users intellectual curiosity. Various embodiments will include artistic decoration and produce sounds which will further enhance the learning experience for users.
- Although the description above contains many specifics, these should not be construed as limiting the scope of the invention, but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus, the scope of this invention should be determined by the appended claims and their legal equivalents. Therefore, it will be appreciated that the scope of the present invention fully encompasses other embodiments which may become obvious to those skilled in the art, and that the scope of the present invention is accordingly to be limited by the appended claims, in which reference to an element in the singular is not intended to mean “one and only one” unless explicitly so stated, but rather “one or more.” All structural, chemical, and functional equivalents to the elements of the above-described preferred embodiment that are known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device or method to address each and every problem sought to be solved by the present invention, for it to be encompassed by the present claims.
