The invention generally relates to a ball spinner.
Many people can balance a spinning ball such as on the tip of a finger or other holder such as a post or rod. People trying to learn such skill often have trouble getting the ball spinning and onto the holder, likely because it is difficult to get the ball spinning about an axis and then difficult to transfer the ball onto the holder substantially in line with the spin axis. Some attempts to provide a device that can get a ball spinning and onto a holder are described in U.S. Pat. No. 3,054,217 to E. D'Amato. The inventor built some test devices (shown in
In accordance with one embodiment of the invention, a ball spinner device comprises a base, at least three ball supports supported by the base for supporting a ball and allowing the ball to be spun relative to the base, and a support member for directly or indirectly supporting a ball-engaging member, the support member configured to allow positioning of the ball-engaging member on a top center of the ball for at least stabilizing the ball during spinning of the ball.
In various alternative embodiments, the device may include exactly three ball supports. The ball supports may include wheels, omnidirectional casters, ball bearings, or other types of ball supports that allow rotation/spinning of the ball relative to the base. At least a portion of the support member may be movable up and down relative to the ball to allow the ball-engaging member to be placed on the ball and taken off the ball. At least a portion of the support member may be movable or rotatable side-to-side relative to the ball to allow the ball-engaging member to be placed on the ball and taken off the ball. The support member may include a direct-drive motor for supporting and driving rotation of the ball-engaging member. The support member may include a bit and a drive shaft in which the ball-engaging member is mounted to the bottom of the drive shaft and the bit is mounted to the top of the drive shaft to be driven by an external drive device such as a power drill. The support member may include a motor that drives rotation of the ball-engaging member through a transmission system that may include a belt, a chain, gears, or other transmission mechanism. The support member may be configured to hold and support a power tool, such as a power drill, that in turn holds the ball-engaging member. The ball supports may be movable and lockable in different positions to accommodate different size balls. The device may further include feet on a bottom of the base such as for use of the device on a tabletop or other surface, a handle extending from the base such as for handheld use, and/or a clamp for securing the base to a surface.
Additional embodiments may be disclosed and claimed.
Those skilled in the art should more fully appreciate advantages of various embodiments of the invention from the following “Description of Illustrative Embodiments,” discussed with reference to the drawings summarized immediately below.
Other mounting and driving configurations are possible, and the present invention is not limited to any particular type of mounting or driving configuration consistent with the concepts disclosed herein.
It should be noted that the foregoing figures and the elements depicted therein are not necessarily drawn to consistent scale or to any scale. Unless the context otherwise suggests, like elements are indicated by like numerals. The drawings are primarily for illustrative purposes and are not intended to limit the scope of the inventive subject matter described herein.
As described above, the inventor built some test devices (shown in
Exemplary embodiments include a ball spinner device for mechanically spinning a ball at a fairly high speed so as to allow a person to put a holder under the ball and have it balance on the holder.
In any of such embodiments, the jig may be movable in whole or in part in an up-and-down direction and/or a side-to-side (e.g., rotational) direction so that the ball-engaging member can be placed onto the ball for spinning and taken off of the spinning ball to allow for removal of the spinning ball such as on a finger or other holder (e.g., by lifting the ball-engaging member off of the ball and/or moving the ball-engaging member aside). For example, as depicted schematically in
In any of such embodiments, the ball supports may be movable, e.g., relative to a ball center location, in order to accommodate different size balls while maintaining the ball-engaging member at the top center of the ball. For example, all of the ball support may be mechanically coupled to move inward or outward along radius, e.g., along or within ball support guide slots as depicted schematically in
In any of such embodiments, without limitation, the device may be configured for tabletop use (in which case the bottom of the base may include feet or other feature(s) such as to hold the device in place), for handheld use (e.g., including a handle extending from the bottom of the base), or for clamping to a surface (e.g., at the edge of a table).
Generally speaking, the distance between the bottom of the ball and the base would be sufficient to allow the user to place a finger or other holder under the spinning ball for removal from the ball supports, although other configurations are possible such as, for example, providing a cut-out section in the base to provide greater access to the bottom of the spinning ball.
While various inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.
Various inventive concepts may be embodied as one or more methods, of which examples have been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.
All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
Although the above discussion discloses various exemplary embodiments of the invention, it should be apparent that those skilled in the art can make various modifications that will achieve some of the advantages of the invention without departing from the true scope of the invention. Any references to the “invention” are intended to refer to exemplary embodiments of the invention and should not be construed to refer to all embodiments of the invention unless the context otherwise requires. The described embodiments are to be considered in all respects only as illustrative and not restrictive.
