Benefits of technology

[0006]In accordance with an embodiment of the present invention, a marker for a sports field comprises an elongated substantially vertical device for marking a field position associated with a game playable on the sports field using an object that may become airborne. The field position is used to determine compliance of the object when airborne with a rule of the game. The apparatus also comprises a source for emitting an elongated generally vertical beam of electromagnetic radiation adjacent to the device to help mark the field position.
[0008]In accordance with still another embodiment of the invention, a method is provided for marking a field position on a sports field associated with a game playable on the sports field using an object that may become airborne. The field position is used to determine compliance of the object when airborne with a rule of the game. The method comprises the steps of positioning an elongated substantially vertical device to mark the field position and emitting an elongated generally vertical beam of electromagnetic radiation adjacent to the device to help mark the field position.

Problems solved by technology

The visibility of such position markers may be limited during the course of a game due to environmental factors, such as wind, rain, snow, and darkness, or due to heavy foot traffic by participants in the game.
The limited visibility of the position markers may affect proper officiating of the game by referees and other game officials.

Embodiment Construction

[0021]FIGS. 1 through 3 illustrate a marker 10 for a sports field 12, in accordance with an example of the present invention. The marker 10 includes a device 14 for marking a field position associated with a game playable on the sports field 12 with an object that may become airborne. More particularly, the device 14 is part of a goal post 16 for the game of American football. The goal post 16 includes two substantially vertical uprights 18 and 20, a cross bar 22 connecting lower ends of the uprights, and a gooseneck 24 supporting the uprights and the cross bar. One end of the gooseneck 24 is connected at or about the midpoint of the cross bar 22. The gooseneck 24 extends downward and rearward from the cross bar 22 to an end that is mounted on the sports field 12.

[0022]The uprights 18 and 20 and cross bar 22 are used to determine whether a football (not shown), when kicked, has complied with the football rule concerned with, for example, scoring a field goal. The relevant rule gener...

Description

RELATED APPLICATION[0001]This application claims priority from U.S. Provisional Application No. 61 / 108,973, filed Oct. 28, 2008.FIELD OF THE INVENTION[0002]The present invention relates to a marker for a sports field and a method for marking a sports field and, more particularly, to a sports field marker that emits a substantially vertical beam of electromagnetic radiation and a method for marking a sports field by emitting a substantially vertical beam of electromagnetic radiation.BACKGROUND OF THE INVENTION[0003]Various games played on sports fields use objects, such as balls, that may be become airborne. The rules of such games may involve determining whether such balls or other game objects, when airborne, cross one or more positions on the sports field. The positions are typically marked with visible devices, which may be structures, such as goal posts, or non-structural indicia, such as paint. The visibility of such position markers may be limited during the course of a game d...
