EPILATOR
An epilator includes a housing, a drive mechanism, and an epilation head mounted on the housing. The epilation head includes a barrel rotatable about a longitudinal rotation axis of the barrel and operatively connected to the drive mechanism for driven rotation of the barrel about its rotation axis. The barrel has an outer surface spaced transversely from the barrel rotation axis. The barrel has a convex longitudinal contour across at least a portion of the barrel outer surface. The barrel further has a plurality of sets of tweezer plates accessible from the outer surface of the barrel. Each set includes a first tweezer plate and a second tweezer plate. At least one of the first and second tweezer plates is moveable relative to the other one of the first and second tweezer plates for contact with each other in response to rotation of the barrel.
This application claims priority to provisional application Ser. No. 61/788,012, filed Mar. 15, 2013, the entire specification of which is incorporated herein.
FIELDThe field of the invention relates generally to epilators and more specifically an epilator having a rotatable convex barrel.
BACKGROUNDEpilators are devices configured to grasp and pull or pluck hair from a user, including portions of the hair below the skin surface. Often epilators include a plurality of gripping members in the form of set of tweezer plates supported by a rotatable barrel. At least one of the tweezer plates of the set of tweezer plates is moveable relative to the other as the barrel rotates to grasp and pull hair from the user. Known epilators have cylindrical barrels or concaved barrels (i.e., barrels having a concaved longitudinal contour). That is, the outer surface of known epilator barrels is generally flat or concaved. However, epilators having cylindrical and concaved barrels are unable to adequately pull hair from curved portions of the body (e.g., the underarms, the bikini area, the back of the knees). There is thus a need for an epilator having a barrel curved to better interface with the curves of the user's body, including the underarms, bikini area, and the back of the knees.
Additionally, in typical epilators, a transmission gear that operatively connects the barrel to drive motor in the handle is located at one end of the barrel, for example longitudinally between the barrel and a mount or cam plate that supports the barrel. There is need, however, for a transmission gear that is located longitudinally outward of the mount or cam plate to permit a reduction in size of the transmission gear. This would allow for an improved gear train ratio from the drive motor to the barrel.
BRIEF DESCRIPTIONIn one aspect, an epilator generally comprises a housing, a drive mechanism, and an epilation head mounted on the housing. The epilation head comprises a barrel rotatable about a longitudinal rotation axis of the barrel. The barrel is operatively connected to the drive mechanism for driven rotation of the barrel about its rotation axis. The barrel has an outer surface spaced transversely from the barrel rotation axis. The barrel has a convex longitudinal contour across at least a portion of the barrel outer surface. The barrel further has a plurality of sets of tweezer plates accessible from the outer surface of the barrel. Each set comprises a first tweezer plate and a second tweezer plate. At least one of the first and second tweezer plates is moveable relative to the other one of the first and second tweezer plates for contact with each other in response to rotation of the barrel.
In another aspect, an epilator generally comprises a housing, a drive mechanism, and an epilation head mounted on the housing. The epilation head comprises a barrel rotatable about a longitudinal rotation axis of the barrel. The barrel is operatively connected to the drive mechanism for driven rotation of the barrel about its rotation axis. The barrel has longitudinally opposite ends, a longitudinal center, and a diameter. The diameter of the barrel at the longitudinal center is greater than the diameter of the barrel at least at one of the longitudinally opposite ends thereof. The barrel further has a plurality of sets of tweezer plates. Each set of tweezer plates comprises a first tweezer plate and a second tweezer plate. At least one of the first and second tweezer plates is moveable relative to the other one of the first and second tweezer plates for contact with each other in response to rotation of the barrel.

In the illustrated embodiment, the convex portion of the outer surface 300 of the barrel 10 is defined by the outer edge 108 of the center disc, the outer edges 124 of the flanking disc, and the outer edges 70 of the end discs 60 of the mounting gears 14. In one suitable embodiment, the convex portion of the outer surface 300 may have a radius in the range of about 10 mm to about 30 mm, and in the illustrated embodiment the radius of curvature is about 19 mm.

In use, the drive mechanism (e.g., a battery or ac motor) of the epilator 1 engages and rotates the transmission gear 64 of one or both the gear members 14. The rotation of the transmission gear 64 by the drive mechanism results in rotation of the barrel 10 about the longitudinal axis LA thereof. More specifically, rotation of the transmission gear 64 results in conjoint rotation of the gear members 14, the pins 200 and springs 230 carried by the gear members, the flanking discs 102 and the center disc 100. During rotation, the fronts 208 of the heads 202 of the pins 200 slidingly engage the cam surface on the second side 48 of the annular cam members 40 of the mounts 28. As the heads 202 rotate over the cams 52 of the cam surface, the respective pin 200 is pushed longitudinally inward (see, e.g., the upper right pin illustrated in
