  An object of the present invention is to obtain a sufficiently long handle when used as a safety razor by using the support as a part of the handle of the safety razor.

  Another object of the present invention is to obtain a grip that is easy to use when the support and the safety razor body cooperate when the support is an electric tool such as an electric trimmer.

  Since both the support of Patent Document 1 and Patent Document 2 are almost completely stored in the handle when the safety razor is used, the support is not used as a part of the handle of the safety razor. Therefore, these safety razors cannot obtain a handle having a sufficient length when used. In addition, when the handle having a sufficient length is adopted in the safety razors of Patent Document 1 and Patent Document 2, the total length of the safety razor when the support is used is the sum of the length of the handle and the entire support. And has a drawback that it is difficult to use because it is too long. The present invention is intended to provide a safety razor that can obtain a handle having a sufficient length without using the entire safety razor when the support is used, and with the support as a part of the handle when the safety razor is used. is there.

  Also, when shaving a beard with a safety razor, work while pulling the safety razor. In this case, since the safety razor is pulled, the cutting edge moves so as to slide on the skin. Therefore, shaving can be performed smoothly only by lightly grasping the handle with a finger. On the other hand, when using the electric trimmer, the operation is performed so as to push the blade edge forward. When the blade edge of the electric trimmer is pushed forward, the blade edge pushes up the skin, so it resists the movement of the blade edge and does not slide smoothly on the skin in combination with the vibration of the motor. Therefore, when the electric trimmer is used, it is necessary to move the electric trimmer while overcoming the resistance of the skin by firmly grasping the handle with the hand. Alternatively, it is necessary to hold the handle of the electric trimmer firmly and push the blade edge by pushing the resistance well so as not to receive the resistance of the skin as much as possible. The same applies to the electric nose hair cutter. Therefore, the present invention is to provide a handle that can grip the handle firmly when the support is an electric tool such as an electric trimmer, and can spread resistance well so as not to receive skin resistance. It is.

The power is turned on and off by rotating the power switch, the working part of the support is housed in the space provided in the razor head, and the support is moved upward with respect to the safety razor body In some cases, an element in which means for preventing rotation of the power switch is provided between the power switch and the support holding portion is added to any one of claims 1 to 5.

  Furthermore, it is preferable that the support of the present invention is a cordless electric trimmer or an electric nose hair cutter provided with a slit outer blade and an inner blade that is rotationally driven.

  According to the first aspect of the present invention, the support holding portion is present below the razor head, the support is elongated and has a gripping portion, and the gripping portion extends from the middle portion of the support to the support end portion in the length direction. The support is coupled to the support holding portion so as to be rotatable around a rotation axis extending in the lateral direction with respect to the support at a base portion of the gripping portion, and an action portion is provided on the opposite side of the support gripping portion. When shaving with the safety razor body, the action part is placed in a space provided in the razor head, and the grip part extends below the support holding part and cooperates with the support holding part to handle the safety razor. When the support is used, the support can be rotated to a position where the working portion can be used. Therefore, by using the grip portion of the support as a part of the handle of the safety razor, a sufficiently long handle can be obtained when the safety razor is used.

Claim 2 defines that when a safety razor is used, the side of the safety razor facing the face surface is defined as the front side, and the side opposite to the front side is defined as the rear side. This is a configuration with walls. Accordingly, since the action portion of the support placed in the space portion is covered by the rear wall of the space portion, the finger addressed to the rear surface of the safety razor does not touch the action portion when the safety razor body is used.

According to a third aspect of the present invention, a rear wall is provided on the upper portion of the support holding portion, and when the support is used, the support gripping portion abuts on a receiving portion provided on the rear wall, and the support extends in the length direction of the safety razor body. It is the structure used in the state inclined with respect to. With such a configuration, the support of the present invention corresponds to a pistol barrel and the safety razor body corresponds to a pistol handle. Since the pistol has a large impact when the bullet is fired, the handle is in the position where the handle is most firmly held against the force received from the barrel, and the handle turns the barrel well to aim at the target reliably. It is in a positional relationship. Therefore, by gripping the safety razor body like a handle, it is possible to work while holding the support firmly in a stable state. Especially when the support is an electric trimmer, if you grip the safety razor body like a handle, you can hold the handle firmly without being affected by the vibration of the motor, and you can use the electric trimmer while overcoming skin resistance It can be moved easily. Alternatively, the resistance can be applied well so as not to receive skin resistance when the blade edge is pushed forward. The same applies to the electric nose hair cutter whose support includes a slit outer blade and an inner blade that is rotationally driven.

According to a fourth aspect of the present invention, a pair of journal shafts are provided on both side portions through which the rotation axis of the support passes, and journal shaft bearings are provided on the support holding portion. Therefore, the support can be rotated with respect to the support holding portion with the journal axis as the rotation axis.

Rotation prevention means are provided for preventing forward rotation of the end of the support when the support moves upward relative to the safety razor body. The state in which the support journal shaft is moved to the upper end of the long hole and the support is moved upward with respect to the safety razor body is the use state of the safety razor body. Therefore, it is possible to prevent the operating portion from popping out due to unexpected rotation of the support when the safety razor is used.

According to a sixth aspect of the present invention, there is provided means for preventing the rotation of the power switch when the working portion of the support is housed in the space provided in the razor head and the support is moved upward with respect to the safety razor body. It is provided between the power switch and the support holding part. Therefore, when the safety razor body is used, it is possible to prevent the power switch from being turned on unexpectedly and the action part from operating.

  Next, embodiments of the present invention will be described. The safety razor 1 has a safety razor body 2 and a support 3. The support 3 is journaled to the safety razor body 2 so as to be rotatable. The safety razor body 2 includes a razor head 4, a cartridge replacement blade 5 having a scissors cutting structure, and a support holding portion 6. The cartridge replacement blade 5 is detachably attached to the upper part of the razor head 4. The razor head 4 is provided with a pair of replacement blade mounting arms 13 for holding the cartridge replacement blade 5 and a mechanism for attaching and detaching the cartridge replacement blade 5 by moving the arm 13. As the mechanism, a known technique for attaching and detaching the cartridge replacement blade is used. The cartridge replacement blade 5 can be attached and detached by pressing a button 8 attached to the rear wall 7 of the razor head 4.

  The razor head 4 has a space 11 surrounded by a rear wall 7 and both side walls 10, 10. A plate-like stopper 12 that protrudes downward from the upper portion of the space portion 11 is provided integrally with the razor head 4 at the front portion of the space portion 11. The stopper 12 is for preventing the support 3 from rotating.

  The support holding part 6 has a pair of arms 9 and 9 extending downward. A long hole 14 extending in the length direction of the arm 9 is provided in the lower part of each arm 9. A journal shaft bearing 15 is formed at the lower end of the long hole 14. The journal shaft 16 of the support 3 is journal-coupled to the bearing 15. The journal shaft 16 has a large-diameter head 17 and prevents the journal shaft 16 from being detached from the bearing 15. Further, in order to prevent the journal shaft 16 in the bearing 15 from naturally moving to the upper portion of the long hole 14, the upper opening of the bearing 15 is formed narrow.

  On the upper part of the support holding part 6, a rear wall 18 is provided which continues from the rear wall 7 of the razor head 4. As shown in FIG. 4, when using the support 3, the support 3 is used in an inclined state with respect to the length direction of the safety razor body 2, but at that time, the gripped portion 20 of the rotated support 3 is used. A receiving part 19 for retaining is provided on the rear wall 18. The receiving part 19 is formed in a concave shape and is adapted to the shape of the cylindrical holding part 20. However, the receiving portion 19 is not limited to a concave shape, and may be a flat shape, for example.

  The safety razor body 1 includes a cover 21 for the cartridge replacement blade 5. The cover 21 covers the cutting edge when the cartridge replacement blade 5 is not used, and covers the front surface and both side surfaces of the cartridge replacement blade 5. Further, when the cartridge replacement blade 5 is used, the cover 21 is moved below the cartridge replacement blade 5 to expose the cutting edge of the cartridge replacement blade 5. A semicircular recess 46 is provided on the front surface of the cover 21 so that the support 3 in the space 11 does not get in the way when the cover 21 is moved downward. Similarly, concave portions 47 and 47 are provided on both sides of the semicircular concave portion 46 so that the both side walls 10 and 10 of the razor head 4 and / or the both side walls of the support holding portion 6 do not get in the way. FIG. 10 is an explanatory view showing a state where the cover 21 covers the cutting edge of the cartridge replacement blade 5. The cover 21 forms a part of the cover body 22. That is, the cover body 22 includes a cover 21, a cover support arm 23, and a connecting rod 24. The cover 21 is supported by a pair of cover support arms 23, and a connecting rod 24 is provided at the base of each cover support arm 23. The cover body 22 is integrally formed of plastic. A pair of cranks 25 are attached to the inner surfaces of both side walls 10, 10 of the razor head 4 and / or both side walls of the support holding portion 6 so as to be rotatable around a fulcrum 26. The pair of cranks 25 are integrally connected by a shaft (not shown) extending in the lateral direction. The end of the crank 25 opposite to the fulcrum 26 and the end of the connecting rod 24 are connected by a shaft 27. A protrusion 28 is provided at the other end of the connecting rod 24. Cam grooves 29 are provided on the inner surfaces of both side walls 10, 10 of the razor head 4 and / or both side walls of the support holding portion 6, and the protrusions 28 move in the cam grooves 29. Therefore, when the cover 21 of FIG. 10 covers the cutting edge of the cartridge replacement blade 5 and is moved downward by hand, the protrusion 28 moves in the cam groove 29 and is shown in FIG. Thus, the cam groove 29 moves to the other end. By this operation, the cover 21 is positioned below the cartridge replacement blade 5 and the entire cover 21 is retracted from the shaving surface constituted by the upper surface of the cartridge replacement blade 5 by the cam motion, so the cartridge replacement blade 5 is used. can do.

  As described above, the cover 21 functions to cover the cutting edge of the cartridge replacement blade 5, but also performs the following functions. That is, FIG. 2 shows the use state of the safety razor. At this time, the support 3 is located at the uppermost position with respect to the safety razor body 2. When the use of the safety razor is completed and the support 3 is used, as shown in FIG. 5, the cartridge replacement blade 5 is covered with the cover 21, the support 3 is lowered, and then the support 3 is rotated. At this time, if the support 3 is lowered and the support 3 is rotated without moving the cover 21 and the cartridge replacement blade 5 is not covered, the upper end of the support 3 hits the cover 21 and the rotation of the support 3 is prevented. Is done. Thus, safety measures are taken that the support 3 cannot be used with the blade edge of the cartridge replacement blade 5 exposed. Further, when the cover 3 moves and moves below the cartridge replacement blade 5 while the support 3 is in use, even if the support 3 is returned to the non-use position after the support 3 is used, it cannot be returned to the cover 21. Thus, it can be understood that the cover 21 does not correctly cover the cutting edge of the cartridge replacement blade 5. Therefore, the safety razor is not stored with the blade edge of the cartridge replacement blade 5 exposed.

  The support 3 is an electric trimmer incorporating a motor and a battery. One end is an action part, and includes a comb-shaped fixed blade and a comb-shaped movable blade. As shown in FIG. 9, the support 3 can use two types of blades, a wide blade 30 and a narrow blade 31. The narrow blade 31 is permanently attached to the end of the support 3. When the power switch is turned on, the movable blade reciprocates left and right. A movable protrusion 32 protrudes on the side surface of the end portion of the support 3, and the movable protrusion 32 is attached so as to reciprocate in the horizontally elongated hole 48 in conjunction with the reciprocating motion of the movable blade.

  The wide blade 30 is attached to the end of the attachment 33. The attachment 33 has a cap shape and can be detachably attached to the end of the support 3 from above the narrow blade 31 using the fitting recess 49. When the attachment 33 is attached to the end of the support 3, the movable blade of the wide blade 30 is connected to the movable protrusion 32. Therefore, when the power switch is turned on, the movable blade and the movable protrusion 32 of the narrow blade 31 reciprocate left and right, and at the same time, the movable blade of the wide blade 30 also reciprocates. Thereby, the wide blade 30 can be used. Note that the narrow blade is not permanently attached to the support 3, but two attachments are prepared, one with a wide blade and the other with a narrow blade. May be.

  As shown in FIG. 6A, three concave portions 34, 35, and 36 are provided on one side surface of the support 3. The upper concave portion 34 is elongated in the length direction, and the bottom thereof is formed so as to gradually become shallower from the upper end to the lower end of the concave portion 34. The lower recess 36 is biased slightly to the right from the center line of the side surface of the support 3.

  FIGS. 7 and 8 show a locking member 39 provided with two convex portions 37 and 38 for locking with the concave portions 34, 35 and 36 described above. The locking member 39 has a pair of support shafts 40, 40 on both sides thereof. The locking member 39 is attached to one arm 9 so as to be rotatable about the support shafts 40, 40. Therefore, the locking member 39 is interposed between the one arm 9 and the support 3. The locking member 39 is provided with a button 41 at its end, and the button 41 is positioned in a hole provided in one arm 9 as shown in FIG. An elastic piece 42 is integrally provided on the locking member 39, and the elastic piece 42 is elastically pressed against the inner surface of the arm 9. By this elastic force, the button 41 is urged in a direction protruding from the surface of the arm 9. At the same time, the convex portions 37 and 38 of the locking member 39 are urged toward the concave portions 34, 35 and 36 of the support 3.

  FIG. 1 shows a state in which the support 3 is at the uppermost position with respect to the safety razor body 2. When shaving with the cartridge replacement blade 5, the cover 21 is moved downward as shown in FIG. One way to hold the safety razor 1 is to hold the grip 20 of the support 3 including the power switch 43 with the palm of the hand, and place the thumb and index finger on both sides of the support holding unit 6. The position of the thumb and index finger with respect to the length direction of the support holding part 6 can be selected according to the user's preference. The support holding part 6 alone is too short as a handle for a safety razor, but this and the grip part 20 of the support 3 can cooperate to obtain a sufficiently long handle. As shown in FIG. 1, the arms 9 and 9 are formed in a plate shape, and the periphery of the arms 9 and 9 is chamfered in a slope shape. As shown in FIG. 2, the cylindrical support 3 protrudes slightly from the arms 9, 9, and the surface of the protruding support 3 and the peripheral inclined surface chamfered by the arms 9, 9 are smooth. Therefore, when one finger grips the surface of the support 3 and the surrounding inclined surfaces of the arms 9 and 9 at the same time, the grip feeling does not deteriorate without causing a step difference. Another way of holding a safety razor is to lower the position of the hand to the lower side of the safety razor and hold the thumb and middle finger in the middle of the arm 9 to show the belly of the index finger. It is used by addressing to the receiving part 19 shown in FIG. In this case, the end of the power switch 43 is supported on the palm. Further, five protrusions extending in the lateral direction are formed on the surfaces on both sides of the support holding portion 6 as anti-slip. As shown in FIG. 1, the protrusion for preventing the slip is formed on the side surface of the cover 21 and the support 3 in addition to the support holding portion 6.

When the support 3 is used from the state of FIG. 1, the button 41 is pressed to release the locking state of the concave portion 35 and the convex portion 37, and the support 3 is moved downward relative to the safety razor body 2 before the support 3. Rotate. FIG. 6B shows a locked state when the support 3 is moved downward relative to the safety razor body 2. After the support 3 is used, the support 3 is reversed so that the support 3 and the arms 9 and 9 are in the same direction, and then the support 3 is moved upward with respect to the safety razor body 2. At that time, the convex portion 37 moves below the concave portion 34 while contacting the inclined bottom of the concave portion 34, gets over the highest portion of the concave portion 34, and is locked to the concave portion 35. When the convex portion 37 is moving in the concave portion 34, the inner surface of the concave portion 34 hits both sides of the convex portion 37, so there is no possibility that the support 3 rotates.

  When the support 3 is moved completely upward with respect to the safety razor body 2, the trimmer blade is positioned in the space portion 11, and the end portion of the support 3 is positioned on the back side of the stopper 12. Therefore, the end of the support 3 does not rotate forward even if the stopper 12 is present. Further, since the end portion of the support 3 is surrounded by a certain portion of the safety razor body 2, the certain portion serves as a cover for the working portion of the support 3. When the support 3 is again moved downward with respect to the safety razor body 2, when the button 41 of the locking member 39 is pressed, the locking member 39 rotates about the support shafts 40, 40 and the convex portion 37 is recessed. The support 3 can be moved smoothly because it is released from 35 and the locked state of both is released.

  Further, when the support 3 is at the lowest position with respect to the safety razor main body 2, the support 3 can be rotated with respect to the safety razor main body 2 by pressing the button 41 as described above. When using the support 3, the support 3 is rotated from this state. FIG. 4 shows the usage state of the support 3. In this state, the grip portion 20 of the support 3 is retained on the receiving portion 19 provided on the rear wall 18 of the support holding portion 6. At the same time, the convex portion 38 of the locking member 39 is locked to the concave portion 36 of the support 3 to prevent the support 3 from rotating. As shown in FIG. 4, when the support 3 is in use, the safety razor body 2 is inclined obliquely downward with respect to the horizontal support 3. In this state, if the safety razor body 2 is gripped as if it is wrapped around the palm of your hand, and the tip of the arm 9, 9 is picked with the thumb and forefinger, the heel support 3 corresponds to the barrel of the pistol, and the safety razor body 2 is the pistol. This is the relationship that corresponds to the handle. The handle of the pistol is configured to hold the pistol firmly and stably. Similarly, the present invention can hold the safety razor body 2 in a stable state like the handle and perform the trimmer operation. When the support 3 is rotated again to return to the original position, when the button 41 of the locking member 39 is pressed, the locking member 39 rotates about the support shafts 40 and 40 and the convex portion 38 comes out of the concave portion 36. Since the locked state of both is released, the support 3 can be smoothly rotated.

  Since the support 3 is an electric trimmer, it has a power switch. The power switch 43 forms an end side portion of the grip portion 20 and is attached to the support 3 so as to be rotatable about a central axis in the length direction of the support 3. The current is turned on and off by rotating the power switch 43. The battery is built in the power switch 43. Since the battery is heavier than the parts of the safety razor 1, the battery has a great influence on the position of the center of gravity of the safety razor 1. Whether the cartridge replacement blade 5 shown in FIG. 2 is used or the support 3 shown in FIG. 4 is used, the power switch 43 containing the battery is located close to the hand. Therefore, a stable operation can be performed when the safety razor 1 or the support 3 is used. When the safety razor 1 is in use, if the arm is placed sideways on the wash basin with one arm 9 of the safety razor 1 facing down, that is, the safety razor 1 is placed sideways on the wash basin so that the arm 9 is in contact with the wash basin. When the support 3 is placed on the washstand, the arm 9 is interposed between the support 3 and the washstand, so that the support 3 is placed on the washstand in a state of being separated from the washstand. The washstand is often wet under the use environment of the safety razor, and there is a concern about the ingress of water into the support 3, but the support 3 is separated from the washstand, so that the concern is eliminated.

  As shown in FIGS. 3 and 6, a locking projection 44 is provided on the side surface of the power switch 43. One locking projection 44 is provided on each side of the power switch 43. When the support 3 is below the safety razor body 2, the locking projection 44 is below the arms 9 and 9 and is exposed. When the locking groove 45 is provided at the lower end of the inner surface of the arm 9 and the support 3 is moved upward, the locking projection 44 is locked to the locking groove 45 and the cartridge replacement blade 5 is shaving It is possible to prevent the power switch 43 from rotating unexpectedly and turning on the power.

  Next, the size of this embodiment will be described. The total length of the safety razor 1 in FIG. 2 is about 150 mm. The total length of the safety razor body 2 excluding the cartridge replacement blade 5 and the replacement blade mounting arm 13 from the safety razor body 2 is about 96 mm. The distance that the journal shaft 16 can move in the length direction of the long hole 14 in the long hole 14 provided in the arm 9 is about 10 mm. The total length of the support 3 in FIG. 6A is about 122 mm. The length from the center of the journal shaft 16 to the lower end of the support 3 is about 60 mm. The total length of the wide blade of the electric trimmer in FIG. 9 is about 13 mm. The total length of the narrow blade is about 5 mm. The sizes are as described above, but the present invention is of course not limited to these numerical values.

  In addition, this invention can take a various aspect based on the structure mentioned above. For example, the support 3 may be an electric nose hair cutter provided with a slit outer blade and an inner blade that is rotationally driven. A well-known technical means is employ | adopted for the structure which rotationally drives an inner blade. In addition, a hand tool such as a shaving brush may be used instead of the electric tool. Moreover, the arm 9 may be only one instead of a pair. In this case, in order to securely hold the support 3 on the arm, it is preferable that the arm is formed firmly and the journal shaft of the support is formed thick. Alternatively, it is preferable that the support 3 can only rotate without being provided with the long hole 14 and cannot move in the length direction. Further, the cartridge replacement blade 5 may be provided with shaving aids on the front and rear and / or on the left and right of the frame member surrounding the blade. It is preferable that tourmaline, shea butter, coconut oil, and charcoal components are added to the shaving aid in an appropriate amount of 0.001 to 5% by weight. The frame member is preferably formed of plastic such as ABS resin or polypropylene resin, and a suitable amount of fluororesin, silicone resin or silicone oil is preferably added to the material in a weight ratio of 0.001 to 5%.
