Abstract

A self-contained portable adjustable boundary marking system capable of use in a variety of athletic settings where a boundary, line, or demarcation is desirable is disclosed. The system is adapted for use indoors or outdoors, on hard surfaces or soft. The system is modifiable and adaptable, and capable of rapid setup and takedown, and the system is thus suited for use in a variety of athletic play and training situations. The system includes boundary markers which contain at least one extensible element such as a tape, string, cord, or cable that may be extended to any desirable length up to the maximum length of the extensible element and attached to other markers of the system or to the playing surface itself to delineate the boundaries of a playing surface or to mark some other meaningful line on the playing surface.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 816,298, filed Jun. 23, 2006.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to athletic field boundaries, and more particularly to a portable and adjustable field boundary that includes markers and retractable boundary marking tape or cord and that allows almost infinite adjustment and configuration of the adjustable field boundary.

[0004] 2. Background and Related Art

[0005] Many sports use a playing field or surface on which a large part of the action of the sport occurs. Often, the field or surface has defined boundaries, where certain events must take place within the boundaries, or certain events that take place outside the boundaries require certain effects. For example, in basketball and soccer, the ball must stay within the boundaries of the court or field, or if the ball crosses outside the court or fiel...

Embodiment Construction

[0028] A description of the embodiments of the present invention will be given with reference to the Figures. It is expected that the present invention may take many other forms and shapes, hence the following disclosure is intended to be illustrative and not limiting, and the scope of the invention should be determined by reference to the appended claims.

[0029] Referring now to FIG. 1, the Figure shows a perspective view of one embodiment of the inventive portable boundary marker system. As shown, this embodiment of the marker has three main components, an upper cone 40 portion or top affixed atop a central body 42 and a base 44 attached to the bottom of the central body 42. The upper cone 40 or top may be flat or may be designed to be of a similar shape to low-profile cones commonly used in sports such as soccer, and this shape provides many of the same benefits of those cones. The base 44 may be designed so that its lower surface provides optimal frictional contact with a partic...
