Definitions
- the present invention relates to a hair removal device of the type comprising a rotary roller provided with pliers intended to pluck unwanted, unwanted hair from the human body.
- This type of device comprises tongs in the form of blades or discs arranged on a rotary roller, the tongs being brought to close and open periodically so as to clamp the hairs close to the skin and, respectively, to evacuate hairs pulled out by the rotation of the roller. Pulling out hair is a very effective method against regrowth, but often it causes significant pain.
- WO 97/00032 has also proposed a rotary pliers epilator comprising a series of movable rollers pushed radially by centrifugal force and / or by springs, rollers which apply mechanical impulses to the skin in order to camouflage the pain caused by pulling out the hairs.
- This solution is however complicated, it also requires precision and high costs for its components.
- the object of the invention is to remedy, at least in part, the abovementioned drawbacks and to propose a tweezer with tweezers intended to apply vibratory stimulation to the area to be epilated substantially at the same time as the pulling of the hairs so to effectively mask the pain felt during hair removal.
- the object of the present invention is to provide a tweezer roller with pliers comprising means capable of effectively generating vibrations in said roller while ensuring good absorption of vibrations in the housing of the appliance.
- Another object of the invention is a hair-removing device provided with reliable pain relief means, of simple construction and which lend themselves to mass production, for lower manufacturing costs.
- a further object of the invention is a hair-removing device with pain-relieving means which act simultaneously with the removal, while leaving visible the epilating area.
- a depilatory device for removing body hair comprising a roller rotatably mounted in a housing intended to be held in the hand, said roller comprising at least two pliers intended to clamp and pluck the hairs, the roller being capable of '' be rotated by an electric motor via a transmission system, since the assembly formed by the roller, the transmission system and the motor is divided into two parts, each part being integral with a support mounted floating by relative to the housing and being driven in vibration at a predetermined frequency, the vibration frequency of one of the parts being in phase opposition with respect to that of the other part.
- the means for driving the depilation roller in rotation are also provided for generating vibrations in the roller at the same time as the removal.
- the vibratory stress on the skin therefore produces an analgesic effect simultaneously with the hair removal process, reducing pain throughout this process.
- the other moving parts of the mechanism are also vibrated, at the same frequency, but in phase opposition.
- roller drive. Means are provided for keeping the assembly in contact during operation.
- the assembly formed by the roller, the transmission system and the electric actuating motor is therefore split into two parts which vibrate at the same frequency, in phase opposition, parts which are mounted on supports mounted floating relative to the housing. so that they can vibrate independently of each other. Consequently, at the time of the vibration drive of the two parts, the vibrations of a first part, in particular of the roller cancel those of the second part, in particular of the motor, so that the vibrations are completely neutralized with respect to a fixed mark, in particular the housing.
- the assembly formed by the roller, the transmission system and the motor is split into two parts of substantially equal masses.
- the parameters of the vibrations generated in these two parts in particular the amplitude, can be better controlled, especially when using a single means of setting in vibration which makes the two parts oscillate at the same time.
- the frequency of the vibrations produced in the rotary roller is greater than 50 Hz.
- the analgesic effect is a function of the frequency of vibratory stimulation.
- the frequency can be advantageously chosen by the speed of rotation of the unbalanced part.
- the elastic means for mounting the assembly in the housing and the moving part are determined so that the amplitude of the vibrations is between 0.1 mm and 1 mm, preferably 0.5 mm.
- the moving part generates vibrations of the rotating roller in a direction substantially perpendicular to the skin.
- the rotary roller therefore strikes the skin vertically, the vibrations being entirely absorbed by the latter, which provides an effective analgesic effect. Oscillatory movements in phase opposition are easily produced in the longitudinal direction of the case.
- the supports of the moving parts are actuated by means of vibrating integrated into the transmission system.
- Vibration systems could have been produced in particular in the form of two integral weights, one of the epilating roller and producing vibrations of a certain frequency and amplitude in the latter, and the other integral with the motor and / or the transmission system and vibrating at the same frequency, but 180 ° out of phase.
- said means for vibrating consist of a rotary part whose axis of rotation is mounted fixed relative to the housing, said rotary part comprising a first toothing provided for cooperating with a first toothed wheel secured to the first support and a second toothing provided to cooperate with a second toothed wheel secured to the second support, the center of the cross section of each toothing being offset on either side of the common axis of rotation in a direction perpendicular to the latter.
- the moving masses are split into two parts, each part being integral with a support mounted floating relative to the housing so that each support can be driven in vibration separately.
- a rotating part provided with at least one toothing because it can be easily integrated into the transmission system or gear train, this part being able to be rotated by a neighboring wheel or by the axle. motor output.
- the constructive parameters of this part in particular the diameters, speeds, modules of its teeth can be calculated so as to obtain an operating speed of the roller and a predetermined vibration frequency of the latter.
- each support performs a translational movement in the direction of the respective eccentricity, so that displacements in opposite directions are obtained from the two supports.
- the first toothing has an eccentricity of equal value, but diametrically opposite to the eccentricity of the second toothing.
- the value of the eccentricity of each toothing relative to its axis of rotation corresponds to half the amplitude of the vibrations obtained in each of the supports.
- the rotating part with two offset teeth induces vibrations of equal amplitudes, but in opposite directions in each of the supports.
- the two teeth rotate, when the distance between the periphery of the first teeth and the periphery of the second teeth is maximum, the two teeth act on the floating supports by moving them away from each other.
- the amplitude of the vibrations obtained in this case is maximum and it is represented by the sum of the eccentricities of the two teeth, in particular twice one of them for equal values of the two eccentricities.
- the eccentricity of the teeth is adjusted so that the maximum amplitude of the vibrations is obtained when the tweezers are in the closed position.
- the maximum amplitude of the stimulation is obtained just before the plucking of the hairs, which gives a very effective stimulation of the skin.
- the supports are slidably mounted on guides in the housing.
- FIG. 1 shows a longitudinal sectional view along the plane B-B of Figure 2 of a hair removal device according to the invention
- FIG. 2 is a sectional view taken along the plane A-A of Figure 1 of a hair removal device of the invention
- FIG. 3a is a sectional view similar to that of Figure 1, but without the housing, the roller, the gear train and the motor;
- - Figure 3b is a sectional view taken along the plane C-C of Figure 3a;
- the appended figures illustrate a device for depilating human skin provided with means for vibrating the rotary roller or the depilatory head 5 of this device so that the cyclic waves resulting from these vibrations cause a pain-relieving effect on the epilating area.
