DETAILED DESCRIPTION OF THE INVENTION                                 Razor                             Detailed description of the invention   The present invention relates to a razor. The invention is particularly useful for safety razor blades that move on the skin surface. Skin contact body for raising hair in front of the skin contact body.   According to the present invention, there is provided a skin contact body provided in or for a razor device. Wherein the skin contact body is spaced apart to form a passage for the hair to pass through Wherein the element has a lateral portion extending laterally within the passage and passes through the passage. Engaging and pulling the bristles, said lateral portion is deflectable by elastic deformation; Without the elements forming the passage being displaced to restrict the adjacent passage, Hair can pass through the passage.   In one embodiment of the skin contact body described herein, a passage is defined therebetween. Having a series of spaced upright elements that pass hairs from front to back of the contact An elastic-flexible transverse portion projects laterally from the element into the passage, and bristles define the passage. As it moves through, it engages the bristles and provides a pulling force in the opposite direction. Preferred of the present invention In a preferred embodiment, the upright element comprises substantially rigid parallel walls. These walls are A cross-sectioned taper with a flank that slopes backwards away from the wall It has a top-shaped elastic lateral projection. Multiple flaps on each side of the wall The distance between the free upstanding edges of the opposing pairs of flaps in the passage is gradually reduced, Gives greater tension to the bristles as they pass through the passage.   The present invention has the skin contact body shown in the embodiment of the present invention, and for example, has a A razor blade device, such as an existing shaving cartridge. Skin contact Form a guard surface to contact the skin in front of the blade during shaving. Also, the skin contact body , It can be arranged between two blades in a blade device having one or more blades .   Hereinafter, embodiments of the present invention will be described in more detail.   FIG. 1 is a schematic view showing a longitudinal section of a skin contact body according to an embodiment of the present invention.   2 and 3 show variants of the skin contactor of FIG. 1, respectively.   4 and 5 are similar to FIG. 1 showing different embodiments of the skin contactor according to the invention. Schematic diagram viewed from various directions.   FIG. 6 is a perspective view of a shaving cartridge incorporating a skin contact body according to the present invention. It is.   Although the skin contact shown in FIG. 1 is shown as a rectangular shape, this is important. Rather, it is a plastic construction integral with the elongated base 1. Extending upward from the base A series of evenly spaced elements form a parallel passage 3 extending the contact body from front to back. It consists of parallel walls 2 confined between them. The top of the wall 2 is in contact with the skin of the contact body The surface and the upper front edge of this wall is rounded off for improved comfort . Within each passage 3 from an adjacent wall, a pair of laterally opposed wings or flaps 4 may be provided. A flexible portion extends. Is each flap the wall to which it is attached Has an upright free edge that is tapered in cross section toward the free end and is sharp against this wall. It is inclined backward at the corner. A pair of flaps facing each other due to this inclination free hair Guides or works through the funnel towards the aperture formed between the edges . The width of the aperture between each pair of flaps in each passage increases from front to back along the passage. It is narrow. Eventually, the rearmost pair of flaps creates an aperture with width A, Because the width is smaller than the diameter of the hair, the end of this flap allows the hair to pass through the passage The hairs are deflected backwards, causing the hair to experience a pulling force based on the friction of the flaps rubbing it You. When the hair is pulled in this manner, the razor blade 6 is positioned just before the front of the razor blade 6 from the skin surface The length of the protruding hairs is temporarily increased, resulting in a tight razor. The pulling force imposed on the hair depends on the flexibility of the flaps and the initial spacing A between these edges. What Determined, so that the hair can be sufficiently extended without causing discomfort Selected. If the flaps are made of elastic enough, the passage between the flap edges The regular spacing may be very small or even zero. Pi between the centerlines of the passage Switch B is preferably as small as possible without compromising the integrity of the construction. When the skin from which the hairs protrude slides on the upper surface of the skin contact, most of the hairs pass. The height of the walls and flaps is not critical, but at least the diameter of the hair Must.   The skin contact body described above is shown as an exemplary embodiment of the present invention, Various changes can be made without departing from the scope of the claims of the present invention. For example, each Within the channel, flexible flaps may be provided on the only wall that encloses the channel. An example For example, if you want a narrow contact body to be placed between two blades of a razor blade device For example, two pairs or a single pair of flaps are provided for each passage.   In the modified skin contact body shown in FIG. 2, the parallel wall 12 forming the passage 13 has a base. A bar or plate extending along the front of the contact, rather than being supported by a base Formed integrally with 10 and the wall extends rearward from the plate. Otherwise this The contact body of the embodiment may be the same as that described in the first embodiment. The wall 12 and the flap 14 extend about 0.1 mm higher than the height of the upper end of the bar 10. I have.   The deformed skin contactor of FIG. 3 has a flexible It has a separate element 20 that creates the lateral portion of each pair in the shape of the flap 24. The flaps having a different arrangement than the embodiment of FIGS. At this time, the hair is lightly pulled in the same manner as in the above embodiment. The individual elements 20 In the middle, the skin is elastically moved backwards to some extent by the force applied by the skin. It is insignificant and does not impair the flap hair tension, even if the hair is tensioned. Absent.   The skin contact shown in FIG. 4 is made of an elastomer and is formed integrally with the base 31. And has substantially parallel walls 32 upstanding from the base. This wall has a straight center And, on both sides thereof, an upright flank formed integrally with the central part and inclined in the lateral direction Having a wedge-shaped transverse portion forming a passage 33 between the wall 32 and the front to back of the member. It forms a taper. The bristles passing through the passage form the lateral part of the wall 32 Based on the elastic compression properties of the material, the side wall of the passage can be deflected, and the width of the passage is smaller than the diameter of the hair. Although it is smaller, it passes the rear end of the passage and slides on the surface formed on the upper surface of the wall 32. Subjected to light tension pulling hair from skin.   FIG. 5 shows another embodiment of the present invention, in which a passage 43 stands upright integrally with a base 41. Element 40, which also has a lateral protrusion in the form of a flap 44. It has the shape of a pillar 42. The flaps are arranged in pairs in opposite directions. To the hair passing along the passage 43 by the column 42 which receives the screw bending force around the axis. The flaps are more elastically deflected. In this way the flap gives the hair a light pull Acts to give. The element 40 of this embodiment is not subject to the force received during the razor. Can be turned backward, but as described with respect to the embodiment of FIG. The bending force is not always important and does not reduce the effect of pulling the hair of the element. No.   In the embodiment of FIGS. 1-3, the flaps are arranged in pairs in opposite directions. Not necessarily. Arrange the flap edges so that they are offset along the passage The desired pulling force is still applied to the hair passing along the It is. Similarly, the flaps in these embodiments are inclined rearward and Approximately vertical along its length or inclined forward with respect to its free edge It is not important to say.   FIG. 6 shows a razor cartridge provided with the skin contact body 50 according to the present invention. The skin contact body 50 is shown only schematically, but not in the embodiment of FIGS. Any one particular form can be employed. Except for the skin contact body 50, the cartridge is It has a structure of knowledge. On the frame between the guard and the cap as shown There are two more supported parallel blades 51,52. The skin contact body 50 is a first blade 51 Of the skin contact body according to the present invention, Can be additionally or alternatively installed between the blades for pulling the hair directly.
