Patent Application
20110201249
Children and adults alike enjoy playing with balls and roller toys, such as push toys. One prior roller toy includes a handle coupled to a base with a hollow dome, which rolls on a pair of wheels that are coaxially mounted. One drawback with such a construction is that the wheels can sometimes be difficult to push for small children, particularly if rolled over uneven surfaces. Another drawback is that undesired noise and jarring can be experienced when the wheels roll along hard and/or bumpy surfaces.
A roller toy apparatus is provided. The roller toy apparatus may include a handle having a grasping portion, an elongate portion and a ball coupling portion, the ball coupling portion including a pair of left and right extensions, each of the left and right extensions including a respective mount extending inwardly into an interior region of the ball coupling portion. The roller toy apparatus may further include a ball rotatably coupled to the ball coupling portion. The ball may be formed of a mesh having a plurality of loop structures, each loop structure surrounding a void, and each of a pair of loop structures may be rotatably coupled to a respective mount of the ball coupling portion, to thereby rotatably couple the ball to the handle. An object such as a rattle may be positioned within the ball.
A roller toy apparatus with the aforementioned configuration provides a number of benefits such as enabling a child to easily grasp and manipulate the roller toy apparatus. Furthermore the ball formed of the mesh enables the roller toy apparatus to be rolled on a variety of surface including bumpy and uneven surfaced. Further in some embodiments the ball may be resiliently deformable, and removable from the ball coupling portion. This enables the roller toy apparatus to be used in different types of play activities, with either the handle and ball coupled as a unit, or with the ball decoupled from the handle.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
As illustrated in
For example, the ball 12 may be formed of a mesh 14 defining a void 16. Mesh 14 may be resiliently deformable. Mesh 14 may include a plurality of loop structures 18 and 20, which have cooperative mating surfaces 48, shown in
An object 24, such as a smaller second ball, may be positioned in an interior of ball 12. The object 24 may be sized so as to be insertable but not easily escapable from the void 16 defined by mesh 14 of ball 12, in some embodiments. In other embodiments, object 24 may be sized such that the resiliently deformable mesh may be deformed and the object may be removed from ball 12. As ball 12 rotates during use, object 24 is jostled about within an interior of the ball 12. In some embodiments, object 24 may be a rattle or other sound-making device, such that sound is generated as object 24 is jostled about during use. It will be appreciated that a multitude of other suitable objects may be positioned in the interior of the ball to provide visual and/or acoustic stimulation to a child. In the illustrated embodiment, object 24 is a transparent, hollow sphere with smaller colored balls contained therein. In other embodiments, object 24 may be provided with visually stimulating features, such as bright colors, a reflective coating, etc., to catch the eye as the object is jostled during use.
Handle 11 includes a first end with a grasping portion 26, which in this embodiment is formed in a ring shape with a void 28 formed therein. The ring-shaped grasping portion 26 is sized so that the hands of a child or other user may hold the grasping portion 26 in respective locations, with fingers extending into void 28, to provide a sufficient grip to push, pull, and rotate the device. In this way, a child may securely manipulate the device, decreasing the likelihood of loosing grip and dropping the device. It will be appreciated that the grasping portion 26 may be formed in other shapes, such as a T shape, Y shape, oval shape, rectangular shape, etc. The ring shape, oval shape, rectangular shape, or other closed shapes enable the roller toy apparatus to be placed on a hook, nail, etc., for storage. Typically, the handle 11 is substantially rigid, although portions of the handle may be flexible or resilient in some embodiments.
Handle 11 further includes an elongate portion 30 connecting the grasping portion 26 to a ball coupling portion 32. In the illustrated embodiment, ball coupling portion 32 is U-shaped, and includes respective left and right extensions 34, each of which is curved to accommodate a ball 12 positioned between the extensions, and each of which is provided with a mount 36 at a distal end configured to rotatably couple to ball 12. The mounts define the axis of rotation of roller toy apparatus 10. The mounts may include a number of structural features that enable ball 12 to rotatably couple to the mounts 36, discussed in greater detail herein with regard to
In some embodiments handle 11 may be hollow, decreasing the weight of the roller toy apparatus 10. However, in other examples, handle 11 may be formed out of a solid piece of material. Further in some embodiments, the handle may be formed from a variety of materials, such as plastic or polymer materials. Specifically in some embodiments, the handle may be formed of thermoplastic using an injection molding process.
Ball 12 may be formed from a variety of materials, such as various plastic or polymer materials. For example, loop structures 18 and 20 may be formed of thermoplastic using an injection molding process. In some embodiments the material used to construct handle 11 may have less elasticity than the material(s) used to construct ball 12. Further, in some embodiments the size, shape, and/or elasticity of the ball 12 and/or mounts 36 may enable the ball to be removed from handle 11, as discussed in greater detail below. Cutting plane 100, shown in
As shown in
As described above, ball 12 is formed of a resiliently deformable mesh that includes a plurality of circular voids surrounded by loop structures having continuously curved (e.g., circular) inner perimeter surfaces. Respective opposed loop structures of the ball 12 are pushed over corresponding stay portions 38, and settle in grooves 40. Each opposed loop structure is seated in the corresponding groove 40, thereby rotatably coupling each of the opposed loop structures to the mount 36 of the corresponding groove 40. Thus, each groove and corresponding loop structure form a rotational interface, or joint, configured to enable rotation of the ball relative to the handle of the roller toy apparatus.
Referring to
A single four-loop assembly 44, and four three-loop assemblies 46 may be affixed together along mating surfaces 48, as indicated in
Loop structures 18 may include mating surfaces 48 that are pentagonal in arrangement, while loop structures 20 may include mating surfaces 48 that are hexagonal in arrangement. It will be appreciated that many other configurations are possible. For example, loop structures 18 may include mating surfaces that are square in arrangement and loop structures 20 may include mating surfaces that are octagonal in arrangement, or any other compatible polygonal arrangements may be used. In such a configuration, the loop structures may still include continuously curved inner surfaces and that include no angular portions so as to be comfortable for gripping, catching and/or throwing, as well as better distributing forces and stress over the surface of ball 12.
Further, while the illustrated embodiments show ball 12 formed with loop structures 18, 20 over its entire surface, it will be appreciated that in some embodiments, the loop structures 18, 20 may be formed only over a portion of the ball 12. For example, in an alternative embodiment, only two loops structures may be provided on opposed sides of ball 12. In another embodiment, portions of the surface of ball 12 may be solid, and other portions may be formed of a mesh of loop structures. Still in other embodiments, accessories, such as a disk or rattle portion, may be inserted into one or more of the loop structures. Thus, it will be appreciated that numerous variations in the structure of ball 12 are possible.
The above described embodiments provide a roller toy apparatus with a resiliently deformable ball that is rotatably coupled to a handle. The roller toy apparatus may be easily rolled forward and backward over uneven surfaces, with any resultant jarring being absorbed by the ball. The roller toy apparatus provides superior maneuverability since it may be tilted to the side for easy turning by a user. Further the roller toy apparatus exhibits whimsical visual and sound effects due to an object being jostled within the ball during use. In addition, the ball and/or object may be removed from the handle for separate play.
It is to be understood that the embodiments herein are illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description preceding them, and all changes that fall within metes and bounds of the claims, or equivalence of such metes and bounds thereof are therefore intended to be embraced by the claims.
This application claims priority to U.S. Provisional Patent Application No. 61/304,487 filed Feb. 15, 2010, entitled Roller Toy Apparatus, which is hereby incorporated by reference in its entirety for all purposes.
