Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A massaging machine comprising a machine base, a mobile frame reciprocally moveable on a machine base, a back-rest frame mounted to the machine base in the manner that its mounting position may be changed and it may be inclined freely, a sliding frame mounted loosely to two guide rods extending parallel to each other in the vertical direction at the back-rest frame, a screw rod parallel to the guide rods being inserted in the sliding frame and the said frame, in turn, being transferable according to the rotation of the screw rod, and two projections for massaging located on the sliding frame arranged in the direction perpendicular to the guide rods.
Claim 2
Dependent Claim
111 words
A massaging machine comprising a machine base, a mobile frame reciprocally moveable on a machine base, a back-rest frame mounted to the machine base in the manner that its mounting position may be changed and it may be inclined freely, a sliding frame mounted loosely to two guide rods extending parallel to each other in the vertical direction at the back-rest frame, a screw rod parallel to the guide rods being inserted in the sliding frame and the said frame, in turn, being transferable according to the rotation of the screw rod, and two projections for massaging located on the sliding frame arranged in the direction perpendicular to the guide rods.
Claim 3
Dependent Claim
22 words
A massaging machine according to claim 1, wherein the said mobile frame is provided with mobile stands which have a shock-absorbing function.
Claim 4
Dependent Claim
