Description

  The present invention relates to an epilator comprising a frame and two parallel epilation heads. Each head includes its own drive system and suspension.

  A mechanical epilation device generally consists of one or two epilation heads. The epilation head includes a plurality of adjacent disks mounted on a pre-tensioned elastic element, typically in a bent configuration, and rotatably mounted on a support. Adjacent discs include spacers and hinge elements that cause these discs to tilt as they rotate so that they deform into epilation tweezers. When set for rotational movement, adjacent disks generally begin to tilt in pairs, forming a diverging opening area and a converging compression area, where several disks are pressed against each other and thus from the skin. Forms tweezers for grabbing and removing the hair.

  Epilators comprising two heads made from two pre-tensioned parallel cylinders in a bent configuration and rotatably mounted on a support are well known to those skilled in the art. Such epilators are shown, for example, in documents EP1839522, FR2690820, US2005 / 0187563, USD611198, EP1839522, BR8600524U, JP2006 / 175026, EP1262117, and JP09056446.

  The epilators disclosed in these documents have a drive system that is common for the two heads, which requires a common transmission that does not allow independent operation of each head.

  However, tests have shown that the effectiveness of the epilator can be improved when both heads operate in a completely independent manner. Operating settings that can be managed independently are, for example, the speed and direction of rotation of the two heads, as well as their placement or suspension flexibility.

  The prior art does not include an epilator with two heads, in which all of the above features such as independent drive systems and suspensions are combined in a single device. Thus, prior art epilation heads cannot be controlled independently.

  The present invention aims to provide a epilator with two parallel heads that, in use, can be managed in a completely independent manner by the individual drive system and suspension specified for each of the two heads. And

  The present invention discloses a epilator comprising a frame and two independent epilation heads, with individual drive systems and suspensions for each of these heads.

Preferred embodiments of the invention include at least one of the following features or any suitable combination thereof:
The epilation head is in the form of a roller with parallel axes with tweezers;
-The distance between the tweezer means is different for the two epilation heads;
-The curvature of the rollers is different for the two epilation heads;
The frame comprises means for adjusting the speed and direction of rotation of each of the two epilation heads;
-The epilation heads can be removed to allow alternation between them during use;
The individual suspension means comprise a spring;
The individual suspension means comprise individual means for adjusting the spring;

  Hair removal is a complex problem because the performance evaluation of a epilator by the user is very subjective. Some users will prefer efficiency, and others will prefer epilators that are less irritating to the skin. In addition, evaluating the epilator also depends on the type of skin of the user and the strength of hair growth. Thus, there are no practically quantifiable mechanical parameters that would make it possible to make the “best epilator”.

  In this specification, the epilation head is defined as a roller having a generally cylindrical shape and equipped with tweezers.

  The epilator 1 according to the invention has an adjusting means 6 for adjusting the speed and direction of rotation for each head 5. Even intermittent changes in speed can be considered with this type of epilator. It also includes a set of interchangeable heads that make it possible to customize the epilator mechanism itself, for example by selecting the complementary curvature of the tweezer means 7 and the blade type or the distance between the disks in a complementary manner have.

  Independent management of the speed and direction of rotation allows the two epilation heads 5 to be used in a complementary manner, for example by adjusting the contour and / or spacing of the epilation disk provided on each head 5. . The diameter and curvature of each head can also be adapted to operate in a complementary manner.

  The test with the epilator according to the present invention shows that if the user can select the direction and speed of rotation of the two heads independently of each other, the user can adjust the previously unknown operation settings. Showed that you would benefit from the flexibility of. The independence of such settings allows each user to select the mode of operation that best fits those settings, which are primarily based on the user's skin type, body hair growth strength, hair removal. Will depend on the area of the body and the sensitivity to pain.

  The epilator 1 according to the invention can function as two completely independent epilators arranged next to each other, the conditions and setting choices determined for one epilator head being It does not interfere with the selection of conditions and settings determined for. Thus, the individual tweezer means 7, the material, diameter and arrangement for each of the heads can be freely chosen, which gives the possibility to establish an optimum degree of complementarity or synergy between the two heads. Therefore, these parameters can be appropriately adjusted to meet the requirements of each user.

  In addition, the arrangement of the two heads is directly controlled by an independent flexible suspension system for the two cylinders. This suspension system can be configured in such a way that it can be adjusted (see Fig. 2), which is quite similar to a car where each wheel is equipped with individual dampers, and has good undulations on the skin. Makes it possible to absorb.
