(11) As exemplarily illustrated in FIGS. 1 to 5, the rotating type razor according to one embodiment of the present invention includes a razor blade cartridge 10 and a mover 100 to rotate the razor blade cartridge. The razor blade cartridge 10 is adapted to be rotated by 180 degrees about a razor head by the mover 100. As such, the razor blade cartridge is variable in position when shaving the upper jaw and when shaving the lower jaw in a state in which a body of the razor has a fixed orientation.

(12) The mover 100 includes a rotating body unit 20, a button unit 30, and a handle unit 40.

(13) The razor blade cartridge 11 may include razor blades 11, a razor blade fixing structure 12, and a rotatable coupler 13.

(14) The razor blades 11 each may take the form of a plate having a bladed end and may be spaced apart from one another.

(15) The razor blade fixing structure 12 provides a fixing space in which ends of the razor blades 11 may be fixed. The razor blade fixing structure 12, as exemplarily illustrated in the drawings, may take the form of a rectangular frame. However, the present invention should not be limited to this shape of the razor blade fixing structure 12.

(16) The rotatable coupler 13 has one end pivotally rotatably coupled to the razor blade fixing structure 12 using a pin and the other end defining a coupling region. The end of the rotatable coupler 13 for pin-coupling with the razor blade fixing structure 12 may have an angled plate shape and the other end of the rotatable coupler 13 may have a semispherical shape to define the coupling region therein. However, the present invention should not be limited to this shape of the rotatable coupler 13.

(17) The rotating body unit 20 may include a rotating cylinder 21, a first elastic member 22, a coupling member 23, a coupling bolt 24, and a connector 25.

(18) The rotating cylinder 21 is configured as a circular cylinder and is provided at one end thereof with a curved surface 21a. Here, the curved surface 21a is configured as a depth varying groove formed in one end of the circular cylinder. In addition, the rotating cylinder 21 has an insertion space 21d defined in a central region of a body thereof for insertion of the first elastic member 22. In addition, the rotating cylinder 21 is formed with an expanded portion at the outer circumference of the body thereof and stop recesses 21b are formed in the expanded portion. In this case, the rotating cylinder 21 further has a sliding surface 21c extending between the stop recesses 21b.

(19) The first elastic member 22 is inserted into the insertion space of the rotating cylinder 21. The first elastic member 22 may have a spiral coil shape.

(20) The coupling member 23 is configured to come into close contact with the first elastic member 22. In this case, the coupling member 23 may be inserted into the insertion space of the rotating cylinder 21 in a state in which part of a body thereof has been inserted into the first elastic member 22. The coupling member 23 may come into close contact with the first elastic member 22 in a state in which the other end thereof is outwardly expanded. In addition, the body of the coupling member 23 may be centrally formed with an insertion region 23a into which the coupling bolt 24 as described below is inserted.

(21) The coupling bolt 24 is fastened to the rotating cylinder 21 or a detent member 50 by passing through the coupling member 23. The coupling bolt 24 serves to prevent the coupling member 23 from being moved from the rotating cylinder 21 by a predetermined distance or more.

(22) The connector 25 is configured as a rotating cylinder having one open end. The end of the connector 25 is coupled to the rotatable coupler 13 and the other end of the connector 25 is coupled to the rotating cylinder 21. In this case, the connector 25 may be coupled to the rotatable coupler 13 and the rotating cylinder 21 via, for example, fitting, bonding, or fusing.

(23) The button unit 30 is configured to come into close contact, at one end thereof, with the curved surface 21a of the rotating body unit 20. The button unit 30 may have bar-shaped protruding pins 31 formed at the end thereof and a button-shaped protrusion 32 formed at a portion of a body thereof.

(24) The handle unit 40 has a first receiving space 41 in which the rotating body unit 20 is received and a second receiving space 42 in which the button unit 30 is received. In this case, a region of the button unit 30 is exposed to the outside of the handle unit 40. In the present embodiment, the handle unit 40 is divided into a left handle and a right handle, which are separable from each other in opposite longitudinal directions on the basis of the center of the handle unit 40. As such, the handle unit 40 may be shaped to easily receive the rotating body unit 20. In addition, the handle unit 40 may further include a silicone packing 40a for prevention of slippage and a coupling cover 40b for coupling of the separated handles.

(25) Now, an operation of the razor as described above will be described. First, the user will perform shaving in a state as illustrated in FIG. 2 and the uppermost region of FIG. 5 in a state where the user holds the handle unit 40 with the hand.

(26) In this case, the user shaves the beard above or below the lips by moving the razor downward.

(27) At this time, when the user attempts to remove the beard at the lower jaw, the user will push the button unit 30 with the hand such that the button unit 30 is moved forward to the razor blade cartridge 10.

(28) Thereby, the button unit 30 gradually pushes the curved surface 21a of the rotating cylinder 21. In this case, the curved surface 21a has a varying depth along the lower end surface of the rotating cylinder 21, thereby being rotated by the push force of the button unit 30. In this way, as exemplarily illustrated in FIG. 5, the razor blade cartridge 10 is rotated by 180 degrees to thereby be oriented upside down.

(29) In this case, the user can shave the beard by moving the razor upward from the lower jaw in a state in which the razor blade cartridge 10 is oriented upside down.

(30) As described above, the rotating type razor according to the embodiment of the present invention allows even a user who is not accustomed to using a reversed handle as in the related art to easily perform shaving because the user can rotate the razor blade cartridge 10 by 180 degrees without orienting the handle 40 upside down.

(31) Meanwhile, the rotating type razor according to one embodiment of the present invention may further include the detent member 50. The detent member 50 is inserted into a receiving space of the handle unit 40. The detent member 50 has protruding pieces 51 formed at one end thereof and a portion of a body of the detent member 50 is expanded so as to be coupled to the handle unit 40 when received in the receiving space of the handle unit 40. In addition, the detent member 50 has a passage hole 52 formed in a body region thereof to allow passage of the button unit 30. The detent member 50 is variable in contact position with the sliding surface 21c during rotation of the rotating cylinder 21 in a state in which ends of the protruding pieces 51 come into close contact with the respective stop recesses 21b. Accordingly, the rotating body 21 is limited in rotation to a location where the protruding pieces 51 of the detent member 50 are inserted into the stop recesses 21b, which serves to prevent idle rotation of the rotating cylinder 21.

(32) In another embodiment of the present invention, the rotating type razor further includes a fixing pin 60, a second elastic member 70, and a pressure pin 80.

(33) FIG. 7 is a sectional view illustrating pivotal rotation of the razor blade cartridge 10 illustrated in FIG. 4.

(34) In this case, the connector 25 further has a through-hole 25a formed in one end thereof and the rotatable coupler 13 further has a second through-hole 13a communicating with the through-hole 25a.

(35) The fixing pin 60 is received in the connector 25 and comes into close contact with the coupling bolt 24. In this case, the fixing pin 60 as well as the coupling bolt 24 may be inserted into a region where the coupling member 23 is inserted. The fixing pin 60 provides a fixing region to which the second elastic member 70 as described below may be fixed.

(36) The second elastic member 70 is received in the connector 25 and is connected to the fixing pin 60.

(37) The pressure pin 80 has one end configured to come into close contact with the second elastic member 70 so as to receive elastic force from the second elastic member 70. The pressure pin 80 passes through the through-hole 25a to thereby come into close contact with the razor blade fixing structure 12 in a state in which a body portion of the pressure pin 80 is received in the connector 25.

(38) Now, roles of the fixing pin 60, the second elastic member 70 and the pressure pin 80 will be described. First, when the rotating body unit 20 is moved forward in the space of the handle unit 40 via forward movement of the button unit 30, as described above, the razor blade cartridge 10 is rotated by the rotating body unit 20.

(39) In addition, the pressure pin 80 is moved forward along with the rotating body unit so as to push the razor blade fixing structure 12 in a given direction, thereby serving to control the angle of the razor blades 11. In this case, the razor blade fixing structure 12 is elastically supported by elastic force of the second elastic member 70.

(40) When performing shaving using the razor as described above, the user can easily control the angle of the razor blade cartridge 10 according to a shaving environment by controlling a forward movement distance of the button unit 30.

(41) FIG. 8 illustrates another embodiment of the rotating type razor according to the present invention. The button unit 30 is formed to vertically extend from the detent member 50 rather than being formed at the handle unit 40.

(42) That is, the button unit 30 of the mover 100 according to the present invention may be located at the handle unit 40, or may be located below the rotatable coupler 13 so as to be vertically connected to the detent member 50. At this time, when the button unit 30 is pushed such that the bar-shaped protruding pins 31 formed at one end of the button unit 30 come into close contact with a lower end surface of the detent member 50, the detent member 50 is pushed upward by the protruding pins 31, thereby causing the razor blade cartridge 10 to be rotated by 180 degrees.

(43) As described above, the position of the button unit 30 may be modified in various ways without and not be limited so long as the button unit 30 may initiate operation of the detent member 50 by being moved (pushed).

(44) The above description of the present invention is given by way of example. Hence, it will be clearly understood that the present invention should not be limited to the configuration as described above in detail. Accordingly, the technical protection range of the present invention should be determined by the scope of the appended claims. That is, the technical protection range of the present invention should be construed as including alterations, equivalents and substitutions of the components of the above-described embodiments.
