The present invention relates generally, as indicated, to a toy including a spherical-shaped object.
Musical instrument toys are popular with children. Certain musical toys, such as a drum, include a spherical object for striking a percussion surface to create the desired sounds. This spherical object, commonly called a striker, is usually attached to a stick which may be held by the child to manipulate the striker. For purely acoustic purposes, the best striker geometry is a spherical shape having a diameter small enough to allow the striker to become lodged in a child's windpipe. This presents a danger of choking should the striker become separated from the stick. With musical toys, safety issues override acoustic objectives whereby, in the past, a striker was non-spherically shaped and/or oversized to prevent choking. Many other toys also incorporate spherical-shaped objects (e.g., paddle games, bowling sets, etc.) and these toys must also often compromise other objectives in the interest of safety when designing and/or sizing the spherical-shaped objects.
The present invention provides a toy including a spherical object that can be of a size which is swallowable by a child, as choking concerns are addressed by other than oversizing of the object. Thus, the toy need not compromise other objectives in the interest of safety when designing and/or sizing its spherical-shaped object.
More particularly, the present invention provides a toy comprising an object which performs a spherical function. The object comprises a generally spherical body having surfaces which together define a spherical surface area that performs the spherical function of the object, and air passages configured to allow for the passage of air through a windpipe regardless of how the spherical body is lodged in the windpipe. More specifically, the air passages are configured so that any diametrical plane through the generally spherical body is intersected by at least one of the air passages and the intercepted air passage(s) extends through the spherical body in a direction perpendicular to the diametrical plane. The air passageways can be formed by grooves in the surface of the spherical body and/or throughways in the spherical body.
These and other features of the invention are fully described and particularly pointed out in the claims. The following description and annexed drawings set forth in detail certain illustrative embodiments of the invention, these embodiments being indicative of but a few of the various ways in which the principles of the invention may be employed.
Referring now to the drawings, and initially to
The spherical object 12 can be of a size which is swallowable by a child (e.g., one to three inch diameter and/or two to three inch diameter), as choking concerns are addressed other than by oversizing of the object. Thus, the toys 10 need not compromise other objectives in the interest of safety when designing and/or sizing their spherical-shaped objects 12.
Referring now to
The illustrated spherical object 12 has four grooves 32, four grooves 34, four grooves 36, and two throughways 38, which, as explained in more detail below, form air passageways through the spherical body 30. The non-grooved regions of the surface area of the body 30 form surfaces 40, 42, 44, 46 and 48 which together define a substantially spherical surface area that performs the spherical function (e.g., striking, bouncing, rolling, etc.) of the object 12.
The four grooves 32 each provides an air passageway in a first direction z, which in the illustrated orientation, is from the top to the bottom of the body 30 or vice-a-versa. (
The grooves 32, 34 and 36, and the throughways 38, are configured to allow for the passage of air through a windpipe regardless of how the object 12 is lodged in the windpipe. (
The air passage(s) are shaped, arranged, and sized so that the intercepted air passage(s) will individually or collectively provide a suitable cross-sectional flow area through the spherical body 30 in any diametrical plane. For example, the cross-sectional flow area in any diametrical plane can be at least about 0.20 in2, at least about 0.30 in2, and/or at least about 0.40 in2. At the same time, the air passage(s) are not so extreme as to detract from the intended spherical-shaped surface of the object 12. For example, the grooves 32, 34 and 36 can invade less than about 40%, less than about 30%, and/or less than about 20% of an analogous spherical surface area without such grooves.
One may now appreciate the present invention provides a toy 10 that need not compromise other objectives in the interest of safety when designing and/or sizing its spherical-shaped object 12.
