Abstract

Abstract An electrical massage instrument is provided which comprises a main body, 8-shaped in section, having connected at its opposite ends a pair of flexible strings each tying a plurality of spherical members in a row. The main body houses an electrically energized source of vibration such as an electric motor having eccentric weights mounted on the motor shaft. One of the tying strings include lead wires for supplying electric power to the source. The free ends of the tying strings are attached with grip members.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 103 words
An electrical massage instrument comprising a main body having a hollow space, a pair of flexible strings connected at one end with the opposite ends of the main body and each tying a plurality of spherical members in a row, a pair of grip members connected with the free end of each tying string, a source of vibration housed within the space of the main body and adapted to produce mechanical vibrations upon energization with electric power, and lead wire means extending through at least one of the tying strings and electrically connected with the source of vibration for supplying electric power thereto.
Claim 2
Dependent Claim 103 words
An electrical massage instrument comprising a main body having a hollow space, a pair of flexible strings connected at one end with the opposite ends of the main body and each tying a plurality of spherical members in a row, a pair of grip members connected with the free end of each tying string, a source of vibration housed within the space of the main body and adapted to produce mechanical vibrations upon energization with electric power, and lead wire means extending through at least one of the tying strings and electrically connected with the source of vibration for supplying electric power thereto.
Claim 3
Dependent Claim 54 words
An electrical massage instrument according to claim 1, further including switch means mounted on one of the grip members which is connected with the lead wire means electrically connected with the source of vibration for controlling the supply of electric power thereto, and a power supply cord taken out of said one grip member.
Claim 4
Dependent Claim 33 words
An electrical massage instrument according to claim 2 in which said switch means includes means for turning the supply of power on and off, and means to vary the level of power supplied.
Claim 5
Dependent Claim 26 words
An electrical massage instrument according to claim 1 in which the source of vibration comprises an electric motor and an weight mounted on the motor shaft.
Claim 6
Dependent Claim 30 words
An electrical massage instrument according to claim 4 in which the motor includes a cooling fan mounted on the motor shaft and said weight is located eccentrically of the fan.
Claim 7
Dependent Claim 33 words
An electrical massage instrument according to claim 4 in which a pair of weights are mounted on the opposite ends of the motor shaft at substantially the same angular position with respect thereto.
Claim 8
Dependent Claim 44 words
An electrical massage instrument according to claim 1, further including a pair of retention means carried on the tying strings at the opposite outer extremities of the series of the spherical members, and urging means for urging the retention means towards the main body.
Claim 9
Dependent Claim 63 words
An electrical massage instrument according to claim 7 in which the urging means is located within each retention means and comprises a coiled spring wound around the tying string, and an auxiliary string extending through the spherical members and engaging with the end of the coiled spring nearer the associated grip member at one end and with the main body at the other.
Claim 10
Dependent Claim 41 words
An electrical massage instrument according to claim 7 in which the retention means is in the form of a sleeve through which the associated tying string extends, the end of the sleeve nearer the grip member being formed with a flange.
Claim 11
Dependent Claim 23 words
An electrical massage instrument according to claim 1, further including a plurality of buffering rings interposed between adjacent elements on the tying strings.
Claim 12
Dependent Claim 53 words
An electrical massage instrument according to claim 1, in which the length of the instrument between the both grip members when the strings are pulled straight is shorter than the distance between the extremities of both hands of an average man opening the arms, but is greater than the breadth of the shoulders.
Claim 13
Dependent Claim 30 words
An electrical massage instrument according to claim 1 in which each of the tying strings is connected with an intermediate portion of the associated grip member at right angles thereto.
Claim 14
Dependent Claim 44 words
An electrical massage instrument according to claim 1 in which the main body has a transverse dimension which is greater than the diameter of any spherical member, and the spherical members have decreasing diameters as they are located further away from the main body.
Claim 15
Dependent Claim 32 words
An electrical massage instrument according to claim 1, in which the main body iS provided with a spongelike, elastic cushioning layer at a portion thereof designed for contact with the human body.
Claim 16
Dependent Claim 18 words
