## Background
FIELD OF THE INVENTION
The present invention relates to bed exercise device adapted to be mounted to a bed and more particularly to a bed exercise device including an assembly of a rail, legs, and brackets adapted to be mounted to the frame of a bed.
BACKGROUND OF THE INVENTION
Exercise devices are provided in a variety of sizes, styles, and means of providing exercise for an individual. The most useful exercise devices provide some means of resistance against which exercises are performed. Resistance is provided in a variety of ways, with a personal exercise device preferably providing lightweight resistance, as opposed to heavy weights or other mechanisms of heavy resistance. Most exercise machines require that the exerciser stand up when using the device, lie down on the device, or sit thereupon. Thus, most exercise devices are built with the assumption that the exerciser is already able-bodied and merely desires to enhance his or her physical abilities.
Recent medical advances have allowed more patients to survive serious injuries or disease processes than ever before. Unfortunately, the period of bed rest required for recovery often leads to severe deterioration of muscle strength and a corresponding inability of the patient to support full body weight upon standing. People confined to hospital beds for extended periods of time have limited possibilities for routine activities such as exercising, using a computer, writing, and reading. In several stages of their recovery period, many people are able and even need to exercise their body, but have no tools or assistance from others for such activities. Further, they may be unable to leave their bed to perform exercise on traditional exercise machines.

Exercise and strengthening of muscles is very important to the maintenance of health. Many people who are sick and bedridden or generally more sedentary lose muscle tone, which leads into a cycle of further loss of muscle strength. Even people who are not bedridden or sedentary often require regular exercise therapy to strengthen muscles to address ongoing maladies such as back pain. Sometimes it is necessary for people to perform exercises first thing in the morning right after waking up and even before getting out of bed to allow them to become mobile. Accordingly, people confined to beds are generally excluded from enjoying the benefits of conventional exercise equipment. The bed exercise device 10, as shown in FIG. 1, is designed to provide a multifunctional and portable fitness device specifically for those who are confined to a bed, although anyone may use this device. While the bed exercise device 10 is described in relationship to a bed, it can also be used with wheelchairs, sofas, benches, and various types of chairs and seats.
