  • a razor system in which the inclined blades with one lower end are fixed in the holder by means of an elastic element made in the form of a base of elastic material, which allows the blades to deviate from their original position and, if necessary, independently occupy any optimal position at an increased angle of inclination .
  • Patent RU M 2174903, IPC B26B 21/22, 2001 is known in which the inclined blades with one lower end are fixed in the holder by means of an elastic element made in the form of a base of elastic material, which allows the blades to deviate from their original position and, if necessary, independently occupy any optimal position at an increased angle of inclination .
  • a known design of a shaving system including a skeleton with a correcting structure, a protective element with a knife structure and an element of a shaving aid, which includes a coaxially arranged distribution head, a neck section and a fixing part, as well as an additional cantilever section located between the distribution head and the neck section and having a cross-sectional width increasing along the longitudinal axis.
  • the shaving aid during shaving is released from the corresponding element with each pass of the shaving system.
  • the razor system rotates as a unit on the handle, following the contour of the shaved skin surface (patent RU JNb 2108233, IPC B26B 21/44, 1998).
  • Known razor unit containing a blade and a stationary interacting with the skin element of a polymeric material located near the blade, this element contains an elongated shell with a skin interacting surface located along the outer surface of the shell, and the inner part passing axially through the entire shell, this shell contains polyethylene oxide and a water-insoluble matrix, and interacting with the skin the element contains a water-insoluble polymer (Patent RU N ° 2203799, MPK B26B 21/44, 1999).
  • a razor system containing a replaceable razor cartridge mounted on a handle, a cartridge rotatable housing, a connecting element, a fuse and a cover
  • the housing is equipped with elements for attaching one or more blades and has a cam surface
  • the connecting element has a rotary support device, which holds the housing rotatably and the central base having a recess and an opening therein facing the cam surface
  • the handle has a support device Cartridge is conjugate with the recess and a spring-loaded plunger (Patent RU N ° 2,214,903, B21B26 / 14 IPC, 2003).
  • the device rotates the body relative to the axis perpendicular to the handle of the razor system, allows you to change the angle at which the cutting edge of the blade, perpendicular to the direction of movement of the razor, cuts the hair, which allows you to somewhat reduce discomfort, however, it is not possible to completely replace the process of cutting hairs by cutting them.
  • the objective of the invention is to expand the range of razor systems for wet shaving while improving shaving comfort and increasing the life of replaceable cartridges.
  • the razor cartridge contains a rotary body, a cover and a safety surface
  • the rotary body is provided with elements for attaching blades with cutting edges, while the blades are mounted at an angle to the vertical plane passing through the longitudinal axis of the handle, and, therefore, at an angle to the direction of shaving, and the fastening elements of the blades are located on the longitudinal sides of the body at an angle to them.
  • the blades are mounted parallel to each other with a step that ensures that each successive blade overlaps the horizontal projection of the previous blade.
  • the blades are mounted in pairs at an angle to each other, with the top of the corner facing the handle.
  • Installing the blades at an angle to the vertical plane passing through the longitudinal axis of the handle means that the blades are mounted at an angle to the longitudinal sides of the razor cartridge with a rotatable housing.
  • the rotary housing grooves are made for rigid fastening of the blades, excluding their deformation along the longitudinal axis.
  • pads can be installed on top of the blade fastening elements along the longitudinal side of the rotary body to help achieve an additional result - skin tightening during shaving and improved razor glide on the skin surface.
  • F is the force applied when shaving
  • Y is the angle of inclination of the force vector applied to the hair to the support reaction force vector.
  • the inventive design of the razor due to the location of the blades in the razor cartridge allows for a minimum value of cos Y, and, therefore, with the same force applied during shaving, it can reduce the reaction force of the support, i.e. shaving force of the hair.
  • the claimed design allows high-quality shaving with less effort applied to the hairs, and, therefore, eliminates unpleasant sensations when shaving.
  • this arrangement of blades can reduce their wear and increase the useful life of the razor cartridge.
  • the location of the blade attachment elements on the longitudinal sides of the body at an angle to them allows you to position the blade at an angle to the direction of shaving, while providing an angle of inclination of up to 45 °, which reduces the force applied to the hairs during shaving by up to 50%.
  • the location of the blades with a step that ensures that each successive blade overlaps the horizontal projection of the previous blade allows for complete overlap of the shaving line, which ensures a clean and high-quality shave.
  • the symmetrical arrangement of the blades relative to the longitudinal axis of the handle with an angle between them, the apex of which faces the handle, increases the comfort and quality of shaving by additional angular stretching of the skin, and also increases the safety of shaving.
  • Figure 1 schematically shows a General view of the razor.
  • the razor contains a replaceable razor cartridge 1, a handle 2 and a connecting element 3, the razor cartridge contains a rotary body 4, a cover 5 and a safety surface 6, while the rotary body 4 is provided with elements for attaching the blades 7, made in the form of grooves, the longitudinal axes of which are located under angle to the longitudinal sides of the housing on which they are located (not shown in the drawing).
  • the connecting element 3 is made in the form of a trapezoidal protrusion (not shown in the drawing) located on the handle 2 and interacting with a groove corresponding to the connecting profile element (not shown in the drawing) located at the base of the cartridge 1.
  • the blades 7 are installed at an angle to a vertical plane that resembles the axis of the handle, and, therefore, at an angle to the direction of shaving.
  • the angle of inclination of the blades is selected based on the location of the blades, their number and dimensions of the housing 4. In the embodiment, when the blades are parallel to each other and mounted on the longitudinal sides of the housing 4 with overlapping horizontal projections, the angle of inclination of the blades to the longitudinal side of the housing 4 is 30 ° -45 °.
  • the task is carried out in full, namely the process cutting of hairs is replaced by cutting them with a minimum force applied by the blade 7 to the hair and the required safety and quality of shaving is ensured.
  • the angle of inclination of the blades to the longitudinal side of the housing 4 is 40 ° -45 °.
  • the rotation of the housing 4 is carried out using any known means (not shown in the drawing), for example, a rotary support device interacting with the cam surface of the housing 4, as, for example, described in the prototype.
  • the inventive razor allows for high-quality and comfortable hair removal from human skin during wet shaving due to the optimal location of the cutting edges of the razor blade blades relative to the surface being treated, as well as to extend the service life of the cutting edges of the blades by reducing the cutting force.
  • the inventive razor can be made in industry from known materials on known equipment.
  • One of the possible industrial applications is the serial industrial production of replaceable shaving cartridges for use in previously known designs of shaving systems.
