Patented June 2Q, 1933 PATENT OFFICE PAULINE KOMENT, OF OAKLAND, CALIFORNIA MASSAGE BEATER Application filed September 5, 1930, Serial No.
This invention relates to a massage beater with hollow rubber balls, which are carried by a resilient holder, and it is characterized chiefly in that the beater consists of a part of a bamboo cane, split ofi in longitudinal direction and bifurcated at the top end of the handle part, the points of the fork, carrying the rubber balls with the aid of known intermediate cups, being bent at right angles to the direction of the beating axis.
As compared with massage beaters, the beating parts of which are carried by resilient holders, for example made of wire, the beater according to the invention presents the main advantage that the special beatingor massage-efiect is attained by the peculiar bodily shape of the beater. A single undivided part is formed, which comprises not only the handle but also the resilient part proper, so that, when beating, a vibration is practically only possible towards the body side and not at all or only very slightly in the opposite direction. Thus a premature tiring of the arm performing the beating is prevented.
An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:
Fig. 1 shows the massage heater in side elevation and Fig. 2 in rear elevation.
The undivided handle forked part a for the balls Z) consists of a portion of a bamboo cane split in longitudinal direction. The handle part for gripping with the hand is designated by 0, the arms of the fork shaped part being designated by d. e designates the intermediate cups in the preferably reduced end of which the ends f of the fork arms terminate. The other end g of each cup 6, hollowed to correspond to the radius of curvature of the balls 6, covers a portion of the ball surface and securely holds the ball 6 preferably by means of a glue-like binding medium.
As compared with massage beaters, the beating parts of which are carried by resilient holders, for example wires, the main advantage of the invention consists in the reinforcing of these holders by making them 479,909, and in Germany September 23, 1929.
in one piece with the handle from a bifurcated portion of a bamboo cane with its hard outer side remote from the massage balls and its soft inner side directed towards the massage balls. Consequently, the amplitude of oscillation of the ends of the bifurcations loaded with the massage balls is greater towards the body than in the opposite direction, in which they encounter the greater resis'tance of the hard outer side of the bamboo cane. Consequently, the arm holding the beater will not fatigue and it is possible to massage the back in a simple and effective manner. The employment of bamboo or similar cane presents the advantage that the handle and the resilient holders carrying the massage balls can be made in one piece in a simple manner by splitting the bamboo cane, without additional parts being necessary for holding together the bifurcation. The beater is therefore not only simple, but also cheap to produce.
The operation is as follows:
The massage beater, when gripped on the handle, is preferably applied to the point of the body, for example also onto the back of the person himself performing the massage, with a quick succession of blows. The parts of the massage beater, which vibrate owing to the resiliency of the fork (Z and balls 6, oscillate chiefly towards the body, whereas the amplitude of oscillation towards the opposite side is considerably smaller, owing to the peculiar construction of the beater and is scarcely perceptible. Consequently the arm holding the massage beater does not tire. As already mentioned even the back can be beaten in a simple and effective manner.
A massage beater formed from a section of a longitudinally split bamboo cane, said section being bifurcated longitudinally for a portion of its length to provide a pair of resilient arms, the outer side face of each of said arm portions being relatively hard and the inner face thereof being relatively soft, the outer ends of the arms being bent at substantially right angles in directions away from the hard outer side faces of the arms and hollow rubber balls fitted to the outer terminal ends of the arms, the harder outer sides of the bamboo cane arms resisting vibrations in directions toward the same to 5 relieve strains on the hands and arms of the user.
In testimony whereof I aflix my signature.
