Each guide rail includes an upper or first end, a lower or second end, an upper or vertical section located adjacent the upper end, a lower or horizontal section located about the lower end, a bend section connecting the vertical section and horizontal section of the corresponding guide rail, an outer side, an inner side, and a guide channel extending from the vertical section into the horizontal section and running along the inner side of the guide rail. The guide channel includes a plurality of gear teeth for engaging with a plurality of driving gears of a plurality of feet massage roller devices when the plurality of feet massage roller devices move upward and downward in a generally vertical direction along the vertical section and bend section from the upper ends toward the lower ends of the guide rails and vice versa, respectively, and moves forward and rearward in a generally horizontal direction along the horizontal section.

Each of the upper connecting bar and lower connecting bar has a first end, a second end, and a body portion extending from the first end to the second end, respectively. The upper connecting bar is secured, attached or connected to the upper ends of the guide rails, while the lower connecting bar is secured, attached or connected to the lower ends of the guide rails. The upper connecting bar and lower connecting bar help to stabilize the frame and the positioning of the guide rails relative to one another.

The feet massage roller assembly includes: a plurality of feet massage roller devices; a worm gear device; and a motor. The plurality of feet massage roller devices may be moved along the guide channels of the pair of guide rails by the motor powering the worm gear device to rotate the plurality of feet massage roller devices such that the plurality of feet massage roller devices move along the guide channels while also providing massaging benefits or effects to the bottoms or soles of the feet and backsides of the ankles and calves of the user.

Each feet massage roller device has a first end with a rotational shaft that is connected to the worm gear device, a second end that has a plurality of driving gears for engaging with the corresponding guide channel of the guide rails, and a main massage roller positioned between the first end and second end of the feet massage roller device. Each main massage roller has a plurality of smaller massage rollers surrounding the outer surface of the main massage roller. Thus, preferably, the plurality of smaller massage rollers make contact with and provide massaging benefits or effects to the bottom or sole of the feet and backside of the ankle and calves of the user as the plurality of feet massage roller devices move along the guide channels of the guide rails.

The worm gear device is in communication with or connected to the motor such that the worm gear device is powered by the motor to rotate the plurality of feet massage roller devices via the rotational shafts so that the plurality of feet massage roller devices can move along the guide channel.

The motor powers the worm gear device to rotate the plurality of feet massage roller devices via the rotational shafts so that the plurality of feet massage roller devices can move along the guide channels of the guide rails.

Each of the two sets of calf massage devices includes: a first or upper calf massage device; and a second or lower calf massage device. Both of the upper calf massage device and lower calf massage device of each set are secured or attached along the vertical section of the corresponding guide rail such that, preferably, the upper calf massage devices face toward one another and the lower calf massage devices face toward one another.

Preferably, each of the upper calf massage devices and lower calf massage devices has an attachment plate, a wiring coil secured or attached to the inner side of the attachment plate, and a metal core or plunger secured or attached to the inner side of the wiring coil. Preferably, the wiring coil is an energized solenoid coil that produces linear movement of the corresponding metal core or plunger so that punching massaging effects is provided to the calves of the user. Thus, preferably, the plurality of metal cores or plungers make contact with and provide punching massaging benefits or effects to the sides of the calves of the user when the two sets of calf massage devices are in use.

Limit sensors control the traveling distance of the plurality of feet massage roller devices along the guide channels of the guide rails in either direction, and prevent the plurality of feet massage roller devices from exiting the guide channels at either end of the guide rails.

As another aspect of the present invention, the invention is directed to a chair, preferably a massage chair, having a legs and feet massage apparatus as described above.
