Abstract
An electrically powered depilatory device including a hand held portable housing, motor apparatus disposed in the housing, and a helical spring comprising a plurality of adjacent windings arranged to be driven by the motor apparatus in rotational sliding motion relative to skin bearing hair to be removed, the helical spring including an arcuate hair engaging portion arranged to define a convex side whereat the windings are spread apart, and a concave side corresponding thereto whereat the windings are pressed together, the rotational motion of the helical spring producing continuous motion of the windings from a spread apart orientation at the convex side to a pressed together orientation at the concave side and for engagement and plucking of hair from the skin, whereby the surface velocities of the windings relative to the hair greatly exceeds the surface velocity of the housing relative thereto.

4923460 - Spring element for hair-removal device - Owned by Aris Enterprises, Ltd. (New York, NY)

A hair removal device comprising a wire shaped in the configuration of a coil spring having a plurality of loops and an arcuate axis and a handle mounting the coil spring for rotation of the spring about the axis, the surfaces of the wire being roughened about the entire circumference and along the entire length of the wire so that mutually opposed surfaces of adjacent loops of the spring are roughened, whereby the performance or the hair removal device is substantially enhanced.

4988353 - Depilatory device and hair-plucker body for use therein - Owned by Hair Remover Ltd. (Tel-Aviv,IL)

A depilatory device includes a flexible plastic cylindrical member formed with a plurality of circumferentially-extending slits, the plastic member being rotated about its longitudinal axis while supported in an arcuate position such that the slits open and close during rotation of the plastic member to receive and pluck the hairs. The plastic member includes a high-strength flexible core imparting mechanical strength, and the slits are formed with corrugated or otherwise non-planar faces to enhance their gripping power when the slits are closed.

5084046 - Depilator - Owned by Mann; Rony (Holon,IL)

There is provided a method and device for depilating hair from various members of the human body, especially arms and legs. The device is based on a rotating head driven by suitable means, which head is provided with an abrasive surface. The method of depilating hair comprises contacting the area of the skin from which hair is to be removed with such rotating surface. The abrasive used is a fine grain one so as to minimize irritation of sensitive human skin.

4726375 - Depilatory device for removing hair - Owned by General Ideas and Products Ltd. (Tel Aviv,IL)

A depilatory device for removing body hair, comprises a manually-grippable housing, and a hair-plucker body rotatably mounted to the housing and having an exposed section formed with a plurality of gaps in its outer surface which open and close during the rotation of the hair-plucker body to receive, pluck, and eject body hair growing on a surface over which the hair-plucker body is moved. The hair-plucker body is a flexible cylindrical member of plastic on elastomeric material having a smooth outer surface formed with a plurality of slits penetrating only partially through the cylindrical member and extending circumferentially thereof. The cylindrical member is rotated about its longitudinal axis and is supported in an arcuate position such that the slits open at the convex side of the cylindrical member during its rotation to receive the hairs between the open confronting faces of the slits, and close at the concave side of the cylindrical member during its rotation to clamp the hairs between the closed confronting faces of the slits.

4825867 - Depilatory device for removing hair - Owned by Hair Remover Ltd. (Tel Aviv,IL)

A device for removing body hair comprises a manually-grippable housing, and a hair-plucker body rotatably mounted to the housing and having an exposed section formed with a plurality of gaps in its outer surface which open and close during the rotation of the hair-plucker body to receive, pluck and eject body hair growing on a surface over which the hair-plucker body is moved. The hair-plucker body includes a pair of drums mounted in spaced parallel relationship, and a belt enclosing the drums and engaging their outer surfaces so as to be rotated thereby. The belt is formed with a plurality of gaps extending circumferentially of the belt. One of the drums is configured so as to cause the portion of the belt engaging it to open its gaps, and the other drum is configured so as to cause the portion of the belt engaging it to close its gaps.
