DESCRIPTION:
BRIEF SUMMARY
The present invention relates to depilating appliances which can be held in one hand in order to displace them on the skin for removing superfluous hairs.
A certain number of appliances of this type already exist.
Thus French patent application No. 2,307,491 describes an appliance in which two pairs of rollers rotate in opposite directions for plucking-out hairs as they engage between these latter. This appliance, however, is of limited efficiency. This is due to the nature of the elements employed for plucking hairs. These latter are in fact not gripped between the rotating rollers in a sufficiently effective manner. Furthermore, the point at which the hairs are effectively gripped between the two rollers, or in other words the point of contact between these latter, is necessarily set back to a substantial extent with respect to the corresponding end of the casing of the appliance.
There exist other depilating appliances which are also equipped with rotating rollers for plucking-out hairs, for example the appliance described in French patent application No. 2,334,320 as well as the appliance described in French patent application No. 2,425,822. However, the efficiency of these appliances is equally unsatisfactory. In addition, the cost price of these appliances is relatively high on account of the presence of the mechanisms which are necessary for driving in rotation the elements used for plucking-out hairs to be removed.
It is for these reasons that the object of the present invention is to provide a small appliance which has the same intended function but which is so designed as to offer optimum efficiency while nevertheless requiring limited capital outlay.
To this end, said appliance is essentially characterized in that the hair-plucking members provided in this latter consists of two jaws placed in oppositely-facing relation and mounted so as to be capable of moving in the same plane while being coupled with an actuating member which is capable of driving them in a reciprocating movement of translation along an axis parallel to the oppositely-facing edges of these jaws whilst guiding means carry out successive separation and clamping of these two jaws during their displacement in one direction and then in the other, the hairs trapped between the two jaws being plucked-out under the action of transverse displacement of these latter while they are maintained applied against each other.
Thus the present appliance has a working head which is of very simple design and does not have any complicated or costly mechanisms. In point of fact, the movable jaws provided in this working head can be displaced by an actuating dog which is driven in a reciprocating movement of translation by means of a mechanism of very simple design of the same type as those provided in many electric shavers. Furthermore, the working head of the present appliance alone constitutes one of the objects of the present invention since this head can be adapted to the actuating dog provided in certain appliances which already exist.
It is worthy of note that said working head has very high efficiency. I fact, the hairs to be plucked can readily engage between the two movable jaws when these latter are located in their position of relative outward withdrawal during their displacement in one direction. They are then powerfully gripped between these jaws when they are applied against each other and are then plucked-out under the tractive force exerted on them by the jaws during their movement of displacement in the opposite direction.
In an advantageous form of construction, the hair-plucking jaws are constituted by the elbowed end portions of two arms or two pairs of arms which are pivotally coupled together at an intermediate point of their length in much the same manner as the two handles of a pair of pliers and the opposite ends of which are placed in contact with stationary cams which are capable of controlling the movements of relative inward and outward displacement of the hair-plucking jaws during the movement of translation of the sy
