Patent ID: 7892190

Claim:
A device for stabilizing a chain in a hyperthermo-therapeutic apparatus, the device comprising: a chain stabilization control unit for stably moving the chain at a constant level regardless of an upward/downward movement of a hyperthermo-therapeutic unit of the hyperthermo-therapeutic apparatus during forward/backward reciprocation of the hyperthermo-therapeutic unit, the chain stabilization control unit comprising: a first hinge shaft having rotatable rollers provided at both side ends of the first hinge shaft and chain-coupling sections provided at both sides of a central portion of the first hinge shaft, level control rods, each of the level control rods having one end hingedly coupled to the first hinge shaft and the other end hingedly coupled to a second hinge shaft, the second hinge shaft being hingedly coupled to the other ends of the level control rods and simultaneously to a lower end of a central portion of a hyperthermo-therapeutic unit support, and the hyperthermo-therapeutic unit support having a body section that mounts the hyperthermo-therapeutic unit, the hyperthermo-therapeutic unit support having the lower end of the central portion of the hyperthermo-therapeutic unit support hingedly coupled to the second hinge shaft and having rotatable rollers coupled to both side ends of the hyperthermo-therapeutic unit support, and wherein the first hinge shaft, the second hinge shaft, and control rods generally lie within a common plane as the first hinge shaft moves forwards and backwards; and a chain-tension control unit for adjusting a tension on the chain, which is configured to be generated during the forward and backward reciprocation of the hyperthermo-therapeutic unit.
