  • the present invention relates generally to a human hair depilatory device of the type illustrated generally in Figs. 6, 13, 15A or 15B.
  • the overall structure of the device may be summarized as including a hand held portable housing, a first element arranged to be driven in rotational motion relative to skin bearing hair to be removed, the first element including a plurality of preferably arcuate hair engaging locations at which adjacent hair engaging surfaces of the first element are spread apart when the hair engaging locations are disposed by rotation at a convex side and at which the adjacent hair engaging surfaces of the first element are moved relatively towards each other in hair engaging arrangement when the hair engaging locations are disposed by rotation at a concave side, the rotational motion of the first element producing motion of the hair engaging locations from the convex side to the concave side for engagement and removal of hair from the skin.
  • a second element disposed interiorly of the first element to define a hair support for hair engaged between adjacent hair engaging surfaces.
  • Prior art devices and particularly a human hair depilatory device constructed and operative in accordance with U.S. Patent 4,524,772 of the present inventors employ a helical spring and a fixed interior guiding element, indicated respectively in Fig. 1 as elements 10 and 12.
  • the arrangement of the helical spring is such that at the concave side only a portion of the spring windings lie sufficiently close together to enable gripping of most human hair therebetween. This portion typically covers about 25% of the perimeter of the spring 10, and is indicated by cross-hatching in the drawing of Fig. 1.
  • the interior guiding element 12 has an outer diameter which is less than one quarter of the outer diameter of the helical spring.
  • Stage 1 shows a hair 14, having a root location 15, engaged between windings of the spring but not grasped thereby.
  • Stage II illustrates the hair 14 being drawn along with the spring windings as they rotate in the direction indicated by arrow 16.
  • Stage III illustrates the hair being grasped between the spring windings within the cross-hatched grasping region at a grip location A.
  • interior element 12 does not appreciably increase the length of the shortest path along which the hair can lie between location A and the root location.
  • stage IV the hair 14 is released in stage V. Thereafter, it may occur that the same hair is again engaged at a location closer to its root location 15 and gripped by the spring windings at a grip location B, as illustrated in stage VI.
  • the hair is tensioned in stage VII, producing pain.
  • stage VIII the hair is removed, as illustrated in stage VIII, because the length of the hair between the location on the hair at which the hair is gripped and root location 15 is sufficiently less than the length of the shortest path along which the hair can lie between location B, intermediate stages VII and VIII, and the root location.
  • the embodiment of Fig. 2 comprises a first element 20, which is preferably a helical spring but which may alternatively be any other suitable element, including a plurality of hair engaging locations at which adjacent hair engaging surfaces of the first element are spread apart when the hair engaging locations are disposed by rotation at a convex side and at which the adjacent hair engaging surfaces of the first element are moved relatively towards each other in hair engaging arrangement when the hair engaging locations are disposed by rotation at a concave side, the rotational motion of the first element producing motion of the hair engaging locations from the convex side to the concave side for engagement and removal of hair from the skin.
  • a first element 20 is preferably a helical spring but which may alternatively be any other suitable element, including a plurality of hair engaging locations at which adjacent hair engaging surfaces of the first element are spread apart when the hair engaging locations are disposed by rotation at a convex side and at which the adjacent hair engaging surfaces of the first element are moved relatively towards each other in hair engaging arrangement when the hair engaging locations are disposed by rotation at a concave
  • the arrangement of the first element is such that along about preferably 75% of the perimeter of the first element, the hair engaging surfaces lie sufficiently close together to enable gripping of most human hair therebetween. This portion is indicated by cross-hatching in the drawing of Fig. 2.
  • a second, interior, element 22 which causes hair grasped by the first element to lie along a path which is preferably generally parallel to the perimeter of the first element.
  • the second element appreciably increases the length of the shortest path along which the hair can lie between location A and the root location, in contrast to the prior art.
  • stage I is essentially the same as stage I of the operation of the prior art apparatus, shown in Fig. 1. Comparing stages II and III of the embodiment of Fig. 2 and of the prior art, it is seen that the configuration of the second element 22 constrains the hair to extend along a path between the hair root location 24 and a grip location A which is longer than the shortest path between those two locations.
  • the hair when the hair is tensioned, as illustrated in stage IV, shown in Fig. 2, the hair generally follows the curvature of the second element 22, defining a much longer path than the corresponding "short cut" along which the hair extends in stage IV of Fig. 1. It can be seen therefore that when grip location A is in the same position in Fig. 1 and Fig. 2, the hair is pulled under tension a longer distance in the embodiment of Fig. 2 than in the prior art shown in Fig. 1. This can be seen at stage IV by observing that, in Fig. 2, the skin is shown deformed near the root much more than in Fig. 1.
  • the percentage of the perimeter of the first element along which hair is gripped between adjacent hair engaging surfaces is increased in the present invention as compared with the prior art. According to a preferred embodiment of the invention, hair is gripped along about three-quarters of the perimeter of the first element, while in the prior art embodiment shown in Fig. 1, the percentage is generally only about 25%.
  • the increased percentage of perimeter along which gripping takes place when combined with provision of the second element according to the present invention, further increases the distance along which the hair is pulled under tension, thus further increasing the likelihood that a hair will be removed when it is tensioned.
  • stage V the hair is removed upon being tensioned the first time, and subsequent tensioning or tensionings of the hair as shown in stages VI, VII and VIII in Fig. 1 are obviated.
  • Figs. 3A - 3I and Figs. 4A - 4I corresponding thereto, which illustrate a plurality of alternative embodiments of depilatory apparatus useful in the present invention. It will be appreciated that the selection of embodiments illustrated herein is not intended to be exhaustive but rather exemplary.
  • the first element is shown herein as a helical spring, it may alternatively be any other type of spring or any other suitable element or collection of elements which are operative to engage hair as described above.
  • Figs. 3A and 4A illustrate an embodiment wherein the first element 20 typically comprises a helical spring and the second element 22 typically comprises a solid, resilient, generally cylindrical element typically formed of plastic.
  • the ratio between the outer diameters of the second element and of the first element is approximately 7:10.

  • FIG. 5A illustrates mounting of apparatus of the general configuration illustrated in Figs. 3A and 4A. It may be seen that one end of the first element 20 is drivingly mounted onto a drive gear 50, while the opposite end of first element 20 is similarly mounted onto a rotatable support element 52. Drive gear 50 and support element 52 are rotatably mounted on respective fixed pin supports 55 and 54. The second element 22 is not directly mounted onto either of elements 50 and 52 but is supported by first element 20 and is normally driven for rotation by the rotation thereof.
  • Fig. 5B illustrates a mounting configuration for apparatus of the general configuration illustrated in Figs. 3B and 4B with the addition of a fixed wire 56.
  • Fixed wire 56 provides a rotatable mounting for drive gear 50 and for rotatable support element 52 and defines the overall configuration of elements 20 and 22.
  • Fig. 5C illustrates a mounting configuration for apparatus of the general configuration of Figs. 3H and 4H and is similar to the mounting illustrated in Fig. 5B, except that spacing rings 42 rotate relative to the fixed wire 56.
