ELECTRODE TIGHTS FOR PULSE SHAPE-UP APPARATUS

Abstract: A pair of electroded tights according to the present invention does not require that one be naked to lie down in taking a beauty treatment as is the case with a conventional beauty treatment apparatus, permitting any way of holding one's body. Six pairs of flat electrodes EL1 to EL6, ER1 to ER6 are attached to so selected places symmetrical relative to the center line of the garment inside, that the flat electrodes may face the underbelly, the inguinal region, the hip, the femoral region, the rear side of the knee and the calf of the body. These flat electrodes EL1 to EL6, and ER1 to ER6 are connected to a pulse beauty treatment apparatus via electrically conductive press studs "a" and a bundle of electric wires "b". The pair of electroded tights may have an elongated tubular bag "d" for containing the bundle of electric wires "b". The elongated tubular bag has a fastener running along its full length for holding together two parts of the bag, and a plurality of relay terminals fixed inside for connecting the electric wires to the flat electrodes EL1 to EL6, and ER1 to ER6.

Description: Technical Field The present invention relates to pulse beauty treatment apparatus whose electric pulse supply applies a train of electric pulse voltage to selected portions of the body with the aid of electrodes, thereby electrically stimulating the body for beauty treatment, and more particularly to a pair of electroded tights for use with such pulse beauty treatment apparatus. Background Art Bioelectric current is flowing ceaselessly in the body to assist cells with their activities and muscles with their constriction. Pulse beauty treatment apparatus can supply a train of pulse current to the body for stimulation, thereby activating cells even more and muscular contraction for improving the function of the body as bioelectric current would do in flowing in the body. In the pulse beauty treatment apparatus suction electrodes are applied to selected portions of the body as in electrocardiography. Alternatively clamp electrodes are used, pinching selected portions of the body. Such electrodes, however, cannot be applied to selected portions of the body with ease, and their application areas are so limited that they are not sure to cover selected areas of the body without fail. A flat narrow or band-like electrode or a large four-sided or sheet-like electrode is large in area, and can be applied to a selected portion of the body with ease.Such electrodes have aluminum foils applied to narrow or four-sided pieces of rubber or cloth. A band-like electrode is wound round a selected portion of the body. A sheet-like electrode is laid on a mat, and one lies down on the sheet-like electrode with one's back or front upside. A sheet-like electrode, however, restrains one from assuming one's postures other than laying oneself down on the sheet-like electrode and, therefore, one is fatigable in one's fixed posture. The winding of the band-like electrode round the selected portion of the body is apt to restrain one's activity. Inconveniently one cannot take such a beauty treatment without taking one's clothes off. The object of the present invention is to provide an electrode structure which permits one to take any desired posture while taking a beauty treatment, totally free of any restriction such as in the conventional sheet-like electrode requiring that one be naked to lie on the sheet-like electrode. GB-A-2 143 135 and US-A-3 610 250 each discloses beauty treatment apparatus comprising a pair of electroded tights having the pre-characterising features of claim 1. Summary of the Invention A pair of electroded tights for use with pulse beauty treatment apparatus, the tights being made of a stretch material having a plurality of flat electrodes of soft inside, stretch material, which flat electrodes are adapted to be connected to an associated pulse generator, characterised in that the pair of electroded tights further comprises an elongate tubular bag containing a bundle of electric wires which are to be connected to the flat electrodes, the elongate tubular bag having a fastener running along its full length for holding together two parts of the bag and a plurality of terminals fixed inside the bag for connecting the electric wires to the flat electrodes The terminals preferably pass through the elongate tubular bag for snapping into electrically conductive studs of the pair of tights. The present invention also comprises a pair of tights according to the invention in combination with pulse beauty treatment apparatus having pulse generator connected to the flat electrodes.

Description of Preferred Embodiments A pair of electroded tights according to one preferred embodiment of the present invention is described below. Referring to Figs. 1 and 2 a pair of electroded tights A has six pairs of flat electrodes EL1 and ER1; EL2 and ER2; EL3 and ER3; EL4 and ER4; EL5 and ER5; and EL6 and ER6 applied inside. These electrodes will be applied to the lower part of the body, particularly to the underbelly, the inguinal region, the hip, the femoral region, the rear side of the knee and the calf of the body when the pair of electroded tights A is worn on the body. The pair of tights is made of expandable fabric to provide a very close fitting garment covering the legs and lower part of the body with its flat electrodes applied to selected portions of the body. The pair of tights has twelve electrically conductive press studs "a". Fig.3 shows twelve electric wires of different lengths, which are used in connecting the flat electrodes EL1 to EL6 and ER1 to ER6 to pulse beauty treatment apparatus. These electric wires are divided in four series-connections each of three electric wires, and the four series-connections are gathered at their one ends as indicated by "b", ending with an electric connector C, by means of which the electric wires can be connected to the pulse beauty treatment apparatus. The twelve electrically conductive press studs "a" permit detachable connection of the flat electrodes EL1 to EL6 and ER1 to ER6 to the pulse beauty treatment apparatus. The flat electrodes are sheets of urethane coated with carbon ink. These flat electrodes are sewed on selected areas of the garment with their coatings facing inward and the selected areas will be put on the underbelly, the inguinal region, the hip, the femoral region, the rear side of the knee and the calf of the body when the pair of electroded tights A is worn on the body. Fig.4 shows a pulse beauty treatment apparatus. It comprises a console 1, a CPU 2, a memory 3, a clock signal generator 4, an interface 5, a digital-to-analog (D/A) converter 6, a pulse generator 7, a current detector 8, an analog-to-digital (A/D) converter 9, a protection circuit 10, a breaker 11, and switching circuits 12A and 12B. A desired kind of beauty treatment and a desired pulse-application pattern are selectively read from the memory 3 with the aid of the CPU 2, and the reference clock signal generator 4 is so controlled that the clock pulses may be divided to provide digital trigger signals to meet the demand. The trigger signals are directed to the pulse generator 7 via the interface 5 and the D/A converter 6, thus permitting the pulse generator 7 to produce pulses of predetermined width and recurrence, which are directed to the primary winding of an associated transformer T1. The current detector 8 is connected to another transformer T2 parallel-connected to the transformer T1, thereby watching and making a decision as to whether or not an excessive current is flowing. The electric current thus detected is directed to the CPU 2 via the A/D converter 9 and the interface 5, so that the CPU2 may permit the protection circuit 10 to respond to the rise of the electric current beyond a threshold value for actuating the breaker 11. The switching circuits 12A and 12B are connected to the series-connection of the secondary windings of the transformers T1 and T2. The flat electrodes EL1 to EL6 an ER1 to ER6 are connected to the switching circuits 12A and 12B via the connector C. The switching circuits 12A and 12B are so designed as to perform their switching actions via associated photocouplers, which are responsive to signals from associated selectors 13A and 13B for making electric connections between the pulse generator and selected flat electrodes. Thus, the flat electrodes EL1 to EL6 and ER1 to ER6 are selectively combined to allow pulse currents to flow in the so selected flat electrodes in such a pulse-application pattern that the desired beauty treatment may be effected on the body. More specifically, one contact is selected among the contacts of each of the switching circuits 12A and 12B, and the two contacts thus selected are closed to provide two closed circuits including two flat electrodes associated with the selected and closed contacts and the selected portions of the body facing the two flat electrodes. Thus, the selected portions of the body are stimulated by pulses from the pulse generator 7 for beauty treatment. One kind of beauty treatment is called "toning", which can be carried out by applying pulses at a relatively low recurrence ranging from 5 to 10 Hz, thereby giving stimulation to a deep point in the body to cause skeletal muscle movement, thereby expediting blood circulation and kneading the selected portion of the body. Another kind of beauty treatment is called "drainage", which can be carried out by applying pulses at a relatively high recurrence ranging from 20 to 100 Hz, thereby giving stimulation to a shallow point in the body to cause the muscle movement under the skin, thereby expediting the flow of lymph in the body and reducing dropsy, if any. Special "toning" or "drainage" uses up-and-down cyclic variation of pulse voltage, thereby giving cyclic variable stimulation to the body. In ordinary "toning" or "drainage" pulse current is allowed to flow in all of the electrodes simultaneously. In time-sequential "toning" or time-sequential "drainage" pulse current is allowed to flow in groups of electrodes one after another, and in time-divisional "toning" or time-divisional "drainage", pulse current is allowed to flow in some selected groups of electrodes simultaneously. Basic modes of pulse-application in a pair of electroded tights include a symmetrical pulse-application pattern; an alternate pulse-application pattern; and a mother-and-daughter pulse-application pattern. Referring to Fig.5, symmetrically paired, left and right flat electrodes EL6 and ER6 EL5 and ER5; EL4 and ER4; EL3 and ER3; EL2 and ER2; and finally EL1 and ER1 are supplied with electric pulses sequentially in a symmetrical pulse-application pattern, thus stimulating the calf, the rear side of the knee, the femoral region, the hip, the inguinal region and the underbelly of the body in the order named. Paired flat electrodes are supplied with pulses for a period of eight to ten seconds, and a one to two second-long break appears before application of pulses to the subsequent paired electrodes. Referring to Fig.6, two adjacent flat electrodes EL5-EL6, ER5-ER6; EL4-EL5, ER4-ER5; EL3-EL4, ER3-ER4; EL2-EL3, ER2-ER3; and EL1-EL2, ER1-ER2 are supplied with electric pulses in a corresponding pulse-application pattern, thus stimulating, on either side, the rear side of the knee and the calf; the femoral region and the rear side of the knee; the hip and the femoral region; the inguinal region and the hip; and the underbelly and the inguinal region. Thus, the portions of the body supplied with pulses are selected sequentially to come closer to the center of the body. Positive and negative pulses are applied to selected paired portions of the body for a period of eight to ten seconds, and a one to two second-long break appears before application of positive and negative pulses to subsequent paired electrodes. Referring to Fig.7, the flat electrodes EL3 and ER3 facing the hip of the body are selected as mother electrodes, and one and the other mother electrode are combined with one and counter daughter electrodes selected among those electrodes other than the mother electrodes. One set of two mother-and-daughter electrode combinations EL3-EL6 and ER3-ER6 is supplied with electric pulses simultaneously, and then another set of two mother-and-daughter electrode combinations EL3-EL5 and ER3-ER5 is supplied with electric pulses simultaneously, and so forth in the mother-and-daughter pulse-application pattern, thus stimulating the calf, the rear side of the knee, the femoral region, the inguinal region and the underbelly of the body in the order named while stimlating the hip all the time. Thus, the portions of the body supplied with pulses are selected sequentially to come closer to the center of the body. Pulses are applied to each of the mother-and-daughter combinations for a period of eight to ten seconds, leaving one to two second-long break before application of pulses to a subsequent mother-and-daughter electrode combination. In these pulse-application patterns, pulsating stimulation is displaced toward the center of the body to stimulate muscles at different portions of the body, thereby driving lymph and blood toward the heart. As a result, lymph is not allowed to be stagnant, and the circulation of blood is expedited. The tight fitting and covering of the legs and lower part of the body in cooperation with the pulsating stimulation has the effect of preventing appearance of dropsy, which otherwise, would appear on the leg while standing and working for a long time. Referring to Fig.8, a pair of electroded tights A can be connected to a portable beauty treatment apparatus B, thus conveniently allowing a wearer to work or walk freely while taking a beauty treatment. Also, the pair of electroded tights A can be connected to a pair of electroded gloves D to improve the treatment effect. Now, the manner in which a pair of electroded tights according to the present invention is used is described below. Fig.9 illustrates an elongate tubular bag for containing a bundle of electric wires. The elongate tubular bag "d" is made of a cloth, and it has a fastener "e" attached to its full length for holding together two parts of the tubular bag "d", and a plurality of terminals "f" fixed inside. The terminals "f" pass through the thickness of the cloth to be exposed inside and outside. Electric wires "g" are connected to the terminals "f" inside, and the terminals "f" snap in the electrically conductive press studs "h" of the pair of electroded tights outside. The elongate tubular bag "d" is unfastened to open wide. A bundle of electric wires "g" is put in the elongate tubular bag, and their ends are connected to the terminals "f". Then, the tubular bag "d" is closed to contain the bundle of electric wires inside. As shown in Fig. 10, the elongated tubular bag "d" is attached to either outer side of the pair of electroded tights "A" by making the terminals "f" snap in the electrically conductive press studs "h". The elongate tubular bag "d" is washable. It is unfastened to remove the bundle of electric wires "g" from the terminals "f", and then, the tubular bag "d" is removed from the pair of electroded tights "A" to be washed. The tubular bag "d" is preferably made of the same stretch cloth as the pair of electroded tights because otherwise, a wearer may have insufficient stretch locally. Figs.11 and 12 illustrate the front and rear sides of a pair of tights A having two elongate tubular bags "d" attached to the opposite sides of the pair of tights A. Fig. 13 shows a bundle of flat arrangement of electric wires "g", similar to the bundle of electric wires "b" in structure. The present invention permits one to take a beauty treatment by wearing a pair of electroded tights, which has a plurality of flat electrodes attached inside. One can have, therefore, a beauty treatment without taking off one's clothes, thus facilitating the practice of beauty treatment even in the presence of people. The beauty treatment does not require that one is naked to lie down, permitting any way of holding one's body. Thus, one is permitted to stand, sit in a chair, walk, work or take an exercise. Advantageously the pair of electroded tights can be so sized as to fit one's body with its flat electrodes applied exactly to selected treatment-effective points of the body. As described in claim 1, a bundle of electric wires to be connected to the flat electrodes is contained in an elongate tubular bag, thereby preventing the tangling of electric wires which, otherwise, would be caused, and at the same time, facilitating the attaching and removing of the electric wires from the pair of electroded tights while improving the appearance of the pair of electroded tights.
