BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates in general to a base such as those used in games like baseball, softball and kickball and, more specifically, to a base which includes impact-absorbing internal structure to minimize player injury. 2. Description of the Prior Art It is known in the art to provide deformable ribs in the underside of a base, each rib extending down from the top wall and parallel with some ribs and angled with respect to others. The ribs are interconnected to each other. These ribs are mostly integral with a center web. See U.S. Pat. Nos. 5,415,385; 5,290,028; and 5,000,447. Another base includes a fabric and rubber core to absorb impact. See U.S. Pat. No. 2,275,547. Another less closely related invention utilized honey-combed cells to absorb the impact of falling children. See U.S. Pat. No. 4,727,697. The present invention differs from the above referenced inventions and others similar in that these prior devices require that any ribs used for impact absorption or deflection be interconnected at least with the top surface and, often, with the side surfaces of the base. Many disclose ribs in a particular configuration such that the ribs are angled one to another or angled relative to a center support to which they are connected wherein a pattern of ribs is formed. The first objective of the present invention is to provide a base that minimizes the danger of injury to a player. The second objective of the present invention is to provide a base in which structure is included for absorbing or deflecting impact; The third objective of the present invention is to provide a base of unitary construction to avoid any loss of integrity on impact. The fourth objective of the present invention is to provide a base that may be rotationally molded and, as such, relatively inexpensive to manufacture by reducing both the necessary materials and the labor required for its assembly. The fifth objective of the present invention is to provide a base that is lightweight yet capable of being securely anchored. The sixth objective of the present invention is to provide a base with internal structural components of structure and orientation to absorb and deflect impact uniformly regardless of the direction of impact. SUMMARYThe present invention differs from the prior art in that it provides a base with improved internal structure designed to absorb or redirect impact without the need to attach said structure to a top surface or to a mid-point. This provides for better absorption of impact and simpler, less expensive construction. Prior art reveals bases with internal structures akin to ribs and integrally formed with the top, bottom and sometimes the side surfaces of the base. The present invention instead includes a base with a plurality of indentations rising from the bottom surface said indentations having a closed top end and an internal surface. The indentations of the preferred embodiment show a footprint on the bottom surface of the base, often generally circular or generally rectangular. The indentations are of varying heights such that the tallest are near the center of the base and the others graduate in height toward and form the sides of the base. A second embodiment includes a top surface just under and in close proximity to which are the closed top ends of the indentations. Other objects, features, and advantages of the present invention will be readily appreciated from the following description. The description makes reference to the accompanying drawings, which are provided for illustration of the preferred embodiment. However, such embodiment does not represent the full scope of the invention. The subject matter which the inventor does regard as his invention is particularly pointed out and distinctly claimed in the claims at the conclusion of this specification. BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a perspective view of a first embodiment of the base; FIG. 2 is a side view of the base of the first embodiment; FIG. 3 is a bottom plan view of the base of the present invention; FIG. 4 is an enlarged vertical cross sectional view of an indentation; Continue reading about Base with improved internal structure...
