ABSTRACT:
In accordance with the invention, a body pressure massaging device is provided which permits a user to massage his back by placing said device between his back and a flat surface. The device comprises a threaded cylindrical dowel which is used to assemble a central narrow circular element having a shaped surface together with a pair of rounded end elements. The central narrow element has a hollow center with threads that mate with the threaded cylindrical dowel so that the central element may be mounted anywhere on the dowel. On each side of the central narrow element there is mounted on the dowel a rounded end element or bell shaped cap. The surface of each of the bell shaped caps has a raised bulbous ridge around the largest circumference of the cap. Each cap has a hollow cylindrical region with threads mating with the threads of the cylindrical member for mounting each cap a specific distance from the central narrow element. The back pressure massage device operates by placing the device on the floor with the user lying on the device and moving along the floor to rotate the device thus effecting a massaging of the back without injuring the spinal column. The individual rounded end elements may be removed from the device and placed on the floor to massage specific muscles, stress points, and feet.
