BACKGROUND

1. Field of the Invention
This invention relates to the field of indoor fitness machines, and more specifically to tray for using while exercising on a treadmill.
2. Description of Related Art
With the busy pace of many working person's daily schedules, one is often unable to find the time to exercise. However, exercise is an important aspect of daily life for many working people. A treadmill is a common way in which one can exercise, either at home, in the office, or at the gym. Often, a television is supported from the ceiling in an area of the gym where many treadmills are being used, allowing those exercising to multi-task at least to the level of watching television while exercising.
The mere watching of television may not be sufficient for many of today's active workforce members. They may seek to layer work related activities onto their exercise regimen. An example of addressing this issue is seen in U.S. Pat. No. 6,520,894 to Mesloh. The apparatus allows for the browsing of reading material while working out a piece of fitness equipment. The apparatus is designed to reside upon the floor adjacent to the sides of the fitness equipment and present a browsing platform in front of the user for the angular support of reading material.
Another example is seen in U.S. Pat. No. 5,257,701 to Edelson, in which a portable exercise desk is disclosed. Once again, the apparatus is adapted to reside upon the floor adjacent to the sides of the fitness equipment.
What is called for is a support for work materials, including the support of a laptop computer, that can be securely fastened to a treadmill and other similar exercise equipment.
