[0005]
In addition, in the example of FIG. 9, since the anti-slip portion 80 is not provided on the front upper half portion B ₁ a of the grip portion B, when the electric razor is used, the grip portion B is held from the front only by the thumb. In addition, since the thumb holds the front upper half portion B ₁ a, the grip of the front holding portion cannot be sufficiently obtained in the arrangement of the non-slip portion 80 as shown in FIG.
[0006]
As described above, in the related art, since the gripping property at the time of gripping the electric razor is insufficient and slippery, when sliding on the skin, it loses the pressing force and slips, and it cannot be shaved with the optimal pressing force, or the shaving blade ( The head portion does not hit at an optimal angle, and as a result, there is a problem that much shaving remains and the shaving time becomes long.
[0007]
The present invention has been made in view of such a point, and an object of the present invention is to provide an electric shaver which is made to be less slippery at the time of use and easy to use by improving grip grip performance.
[0008]
[Means for Solving the Problems]
In the present invention in order to solve the above problems, the elastomeric slip portion 80 continuously arranged from the side B ₂ of the grip portion B which supports the head portion A toward the rear lower half B _{3 b} and has the elastomeric slip portion 80 characterized in that also arranged on the front upper half portion B _{1 a} grip portion B, in such a configuration, hand and sizes, subtle during gripping Regardless of the displacement, the small hill, base, middle and middle knuckles in any one or more of the middle finger, ring finger and little finger, and the little finger hill and thumb hill reliably contact the non-slip portion 80, so that the lateral direction In addition, the grip performance (grip gripping performance) against contact pressure from the back direction is improved, and the non-slip portion 80 made of an elastomer is also provided on the front upper half portion B ₁ a of the grip portion B, so that the thumb end segment is formed. In order to contact the non-slip part 80, Also improved grip for the contact pressure from the front B _1. Therefore, even if there is a difference in the size and holding style of the user's hand, contact pressure is applied to the portion where the non-slip portion 80 is installed, and sufficient grip of the front holding portion can be obtained.
[0009]
Also it is preferable to extend the anti-slip portion 80 of the side B ₂ of the grip portion B to half B _{2 a} on the side surface, in this case, the index finger, middle finger, ring finger, little finger all distal segment is half on the side surface B ₂ a comes into contact with the non-slip portion 80 extending to a.

By also functioning as the operation part of the trimmer, not only the grip performance but also the trimmer operability is improved.
[0012]
Further, it is preferable to dispose the non-slip portion 80 of the upper rear half portion B ₃ a of the grip portion B at substantially the same height as the non-slip portion 80 of the upper front half portion B ₁ a. The terminal end of the thumb contacts the non-slip portion 80 of the half B ₁ a, and the base and middle segments of the index finger contact the non-slip portion 80 of the upper back half B ₃ a, thereby further improving grip at the time of grasping. As well as improving the trimmer operation, the structure is less slippery and easier to operate.
[0013]
Further, by extending the slip portion 80 of the side B ₂ up to a front lower half section B _{1 b} of the grip portion B, and to continuously dispose the anti-slip portion 80 so as to go around the grip portion B preferably, in this case, even when used by gripping the front B ₁ and back B ₃ in the reverse direction, for contacting the retaining portion 80 slip little finger or ring finger, so that sufficient grip can be obtained.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.
[0015]
As shown in FIG. 1, the electric shaver 1 of the present embodiment is roughly composed of a blade head block 2 and a grip block 3, and supports the blade head block 2 near the upper end in the grip block 3. A member is provided. Here, as shown in FIG. 6, a blade head support block 4 is disposed between the blade head block 2 and the grip block 3.
[0016]
First, the configuration of the blade head block 2 will be described in detail with reference to FIGS.
[0017]
The blade head block 2 is mainly composed of a head case block 6 containing a linear motor 5, an inner blade 7, and an outer blade block 8. The vibration of the linear motor 5 in the left-right direction F (FIG. 1). Is transmitted to the inner cutter 7 by the driver 9 at the tip thereof, and the inner cutter 7 and the outer cutter 10 slide with each other, thereby cutting the beard that has entered the blade hole of the outer cutter 10. As shown in FIG. 5, the lower portion of the linear motor 5 is inserted into the head case 12 from above in a state where the linear motor 5 is integrally connected to the motor base 11, and is fixed from below by the head lower screw 13. .
[0018]
As shown in FIG. 5, the head case 12 is fixed from above with a head upper screw 17 via a head case cover 14, a driver waterproof rubber 15, and a rubber pressing plate 16. By fixing the head case 12 with screws, the head case block 6 is configured as a single box housing the linear motor 5. A rubber (not shown) for waterproofing is provided on the lower surface of the head case cover 14, whereby the head case block 6 is configured as a waterproof case. As shown in FIG. 3, a lead wire 18 extending from the lower side of the linear motor 5 has a distal end coupled to a drive circuit in the grip block 3 for driving the linear motor 5. After the waterproof rubber tube 20 is inserted through a hole (not shown) provided in the lower portion of the case 12, the front and rear housings are passed through holes 22 (FIG. 7) provided on the upper surface of the front housing 21 described later. 21 and 22 are connected to the circuit 19 (FIG. 3). The upper end of the rubber tube 20 is press-fitted into a cylindrical hole (not shown) provided on the bottom surface of the head case 12 and then locked from the outside by a locking hole 23a (FIG. 5) of a head stopper 23 described later. After the lower end of 20 is press-fitted into the lead wire cylindrical hole on the upper surface of the rear housing 24, it is inserted and locked in a locking hole 25b (FIG. 7) of a click member 25 described later. That is, a waterproof structure is provided between the head portion A and the box-shaped space 110 of the grip portion B. Further, the head portion A and the grip portion B are connected to each other by the elastic tube 20, and the lead wire 18 is inserted into the elastic tube 20 to be waterproof. Since electric power is supplied to the head portion A from the grip portion B in this state, waterproofing is possible in a state where large relative movement is possible, and cleaning performance is also improved.
[0019]
As shown in FIG. 5, the head case 12 has a protruding portion 12a that protrudes downward only near the center of the bottom surface. By forming a shaft supporting the head portion A on the protruding portion 12a and raising the lower surface positions on both outer sides upward, the left-right inclination of the head portion A can be further increased, and the followability to the skin is also improved. Is what you can do. Moreover, only the protruding portion 12a of the head case 12 on the lower side is covered by the front and rear walls 21a and 24a, and a gap penetrating in the front and rear direction E is provided on both outer sides. It is easy to show that the head part A can be largely rotated left and right, and the structure is such that the whiskers are not easily accumulated. The width L1 (FIG. 2) of the front and rear walls 21a, 24a is smaller than the width L2 (FIG. 2) of the grip portion B in the left-right direction F. This greatly reduces the possibility that the finger enters the movable range below the head in the gripping state with a normal hand, and prevents the finger from hitting the head part A and hindering the movement of the head part A, thereby improving the grip performance. It is the structure which can secure.
[0020]
Here, a mechanism for holding the head portion A in the front-back direction E and a mechanism for preventing backlash in the front-back direction E will be described. A mechanism for holding the head portion A in the front-rear direction E is provided on the front wall 21a. In the example shown in FIG. 5, the head stopper member 23 is attached to the head case block 6 by the pair of front and rear locking protrusions 27 of the head stopper member 23 being engaged with the respective convex portions 26 on both front and rear surfaces of the head case 12. Further, left and right protruding pieces 28, 28 are provided at the upper end on the front side of the head stopper 23, and the protruding pieces 28, 28 are hooked on openings 29 provided on the front wall 21a of the front housing 21. The projection 28 of the head stopper 23 is locked to the front wall 21a, whereby the head case block 6 is held so as not to move in the front-rear direction E (FIG. 1) with respect to the front housing 21. Therefore, even if the pitch between the front wall 21a of the front housing 21 and the rear wall 24a of the rear housing 24 varies, the head case block 6 is always held by the front wall 21a of the front housing 21 and the backlash in the front-back direction E is maintained. Can be prevented. Further, a projection 90 (FIG. 7) is formed so as to extend downward from the lower rear surface of the head stopper 23, and the projection 90 is in sliding contact with the inner surface of the rear wall 24. 6 is prevented in the front-back direction E. In other words, the head case block 6 is guided only in the vertical direction without being inclined in the front-rear direction E by the protrusion 90 sliding on the inner surface of the rear wall 24a of the rear housing 24. Even if a force in the front-rear direction E is applied to A, the head part A does not tilt in the front-rear direction E, and it is possible to prevent the head part A from tilting back and forth as in the related art, making it difficult to shave.
[0021]
As shown in FIG. 5, blade attachment / detachment buttons 30 are provided on both longitudinal end surfaces of the head case 12. Each blade attaching / detaching button 30 is attached in a state of being urged outward by a blade attaching / detaching button spring 31 included in the head case 12.

An inner cutter push-up spring 34 is held in the driver 9 by a spring stopper 35, and the inner cutter 7 is coupled thereto from above, so that the inner cutter 7 is urged upward.
[0023]
Next, the outer cutter block 8 will be described. As shown in FIG. 4, three blades are arranged in the front-rear direction E in the order of the outer blade 10 (net blade), the slit blade 36, and the outer blade 10 (net blade). Each frame is held by a frame-shaped holding frame 38 so that each can be floated independently. The outer cutter 10 is fixed by an outer cutter frame 39, and the outer cutter frame 39 is connected to a holding frame 38 by a blade cover member 40. By engaging the engaging projections 42 (FIG. 5) on the upper part of the blade attaching / detaching button 30 with the engaging holes 41 provided at both ends in the left-right direction F of the holding frame 38, the outer blade block 8 It is held detachably.
[0024]
Next, the configuration of the blade head support block 4 will be described in detail with reference to FIGS. 3, 5, and 6. FIG. As shown in FIG. 5, the head support member 43 is formed in a substantially U-shape, and has a hole 44 at an upper end thereof. On the other hand, the front and rear walls of the head case 12 are provided with support protrusions 45 projecting in the front-rear direction E at two places, that is, four places in total. The front and rear support protrusions 45 are formed at positions that are coaxial when viewed from the front.
[0025]
Here, the two head support members 43 are provided on the left and right, and the upper hole portions 44 are rotatable with respect to the support protrusions 45 of the head case 12 and the head case 12 is moved back and forth from below. Are engaged with each other. As shown in FIG. 3, each head support member 43 is fitted into a pair of left and right vertical groove-shaped guide grooves 46, 47 formed on front and rear walls 21a, 24a of the front and rear housings 21, 24, respectively. Accordingly, the head support member 43 is vertically movably held between the front and rear walls 21a and 24a.
[0026]
Here, the function provided by the two left and right head support members 43 can be described as follows. When the head portion A is pressed at an angle different from the skin surface, both ends of the head portion A hit the skin, and a force for lowering the head portion A is generated. At this time, since the fulcrum of the rotation of the head portion A is the axis of the head support member 43 on the side opposite to the side on which the skin is in contact, the distance from the point of force increases, and the force for rotating the head portion A is reduced. growing. Therefore, since the head part A rotates with a light force until the state along the skin, the skin and the blade come into close contact with each other, so that the electric shaver 1 without shaving can be provided.
[0027]
Further, in this example, an elastic member 100 (FIG. 7) made of an elastomer is arranged on the upper end side of the guide groove 46 on the front wall 21a side. The elastic member 100 is provided at the upper end of the guide groove 46, and when the head support member 43 moves along the guide groove 46, the impact when the floating head support member 43 returns is alleviated by the elastic member 100.

One spring block 50 is provided with a coil spring 51 and a leaf spring 52 vertically. It is held by a spring receiving member 53. The coil spring 51 is held by a projection (not shown) provided on each of the upper and lower spring receiving members 53. The leaf spring 52 is formed in a substantially U-shape, and one piece thereof is fixed by welding a projection of the upper spring receiving member 53. The lower spring receiving member 53 has two protruding portions (not shown) at positions sandwiching the coil spring 51, and the distal end hooks have holes (not shown) formed in the upper spring receiving member 53. ), The spring block 50 is formed. The upper spring receiving member 53 of the spring block 50 contacts the lower surface of the head support member 43, and the lower spring receiving member 53 contacts the bottom surface of the box-shaped space 110 of the front and rear housings 21 and 24, so that the head support member 43 It is supported from below by the spring block 50. With these configurations, waterproofing is possible in a state where the head case block 6 is capable of large relative movement, and cleaning performance is improved. Further, as described above, the head supporting member 43 and the spring block 50, which constitute the urging element, are provided between the head part A and the upper surface side of the box-shaped space 110 of the grip part B. Since the thickness of the portion B is not affected, the thin grip portion B which is very easy to hold can be formed, and the head portion A can be supported over the entire thickness direction of the lower surface of the head portion A. The operation of A is stabilized. Moreover, the head support member 43 rotatably connected to the head portion A is vertically movably held by guide grooves 46, 47 formed inside the front and rear walls 21a, 24a of the housing, and the head support member 43 is spring-blocked. Due to the biasing of the spring at 50, the structure is such that the rotation and vertical movement of the head portion A can be performed.
[0029]
Next, a mechanism for adjusting the spring force of the spring block 50 will be described. As shown in FIG. 3, a fan-shaped flat portion 63 and a hole 62 are formed in an upper portion of one side surface of the rear housing 24, and a lever shaft 64 is inserted through the hole 62. A lever operator 66 is rotatably connected to a protrusion 65 provided at the tip of the lever shaft 64, and the lever operator 66 is disposed on the flat portion 63 of the rear housing 24.

Next, the non-slip structure of the grip portion B will be described. In this example, as shown in FIGS. 1 and 2, over the grip portion down back from the side surface B ₂ halves B _{3 b} of B, non-slip portion 80 consisting of a large resilient member of the friction coefficient, such as elastomeric continuous And the non-slip portion 80 is also provided on the front upper half B ₁ a of the grip portion B. Furthermore, and extending the slip portion 80 of the side B ₂ up to half B _{2 a} on the side surface. A non-slip portion 80 is also provided on the upper rear half B ₃ a of the grip portion B. The non-slip portion 80 provided on the rear upper half portion B ₃ a also serves as an operation portion of the trimmer. Here, it is disposed between the front upper half portion B _{1 a} slip portion 80 and the rear upper half B _{3 a} slip portion 80 of the grip portion B at substantially the same height, from the front B ₁ a holding force of the thumb, holding power of the index finger, middle finger from the back B ₃ is as balanced. There further by extending the slip portion 80 of the side B ₂ of the grip portion B to the front lower half section B _{1 b,} continuously by disposing the slip portion 80 so as to go around the grip portion B . In this example, as shown by the dot portions in FIGS. 1 and 2, the front housing 21 is integrally formed with a non-slip portion 80 from both sides B ₂ to the lower end of the front B ₁ , and both sides are formed on the rear housing 24. It is integrally molded elastomeric slip portion 80 from B ₂ toward the rear lower half B _{3 b.} By combining the front and rear housings 21 and 24, grip the back lower half _B 3 b from the side _{B 2} of B, and from the side _{B 2} over the front _{B 1} bottom end, the slip preventing portion 80 so as to go around the grip portion B Are arranged continuously.
[0034]
Thus, by continuously arranging the slip portion 80 made of elastomer (friction coefficient is large elastic member) from the side face B ₂ of the grip portion B toward the rear lower half B _{3 b,} shown in FIG. 10, "Scissors In both cases of “holding” and “grasping holding” shown in FIG. 11, regardless of the size of the hand or the subtle positional deviation at the time of gripping, the small hill / base in one or more of the middle finger, ring finger, and little finger Since the knot / middle / final knot and the little finger hill / thumb hill surely come into contact with the anti-slip portion 80, grip performance (grip grip performance) against contact pressure from the side and back directions is improved. Further, by disposing the non-slip portion 80 made of an elastomer also in the front upper half portion B ₁ a of the grip portion B, the end of the thumb contacts the non-slip portion 80, so that the gripping property against the contact pressure from the front B ₁ . Is improved.
[0035]
Furthermore, since the extended anti-slip portion 80 of the side B ₂ up to half B _{2 a} on the side, the index finger, middle finger, ring finger, little finger all distal segment is in contact with this non-slip portion 80, further Since the non-slip portion 80 is also provided on the upper back half B ₃ a of the grip portion B, the base and middle segments of the index finger or the middle finger come into contact with the non-slip portion 80.
[0036]
Therefore, even if there is a difference in the size and holding style of the user's hand, contact pressure is applied to the portion where the non-slip portion 80 is installed, and sufficient grip of the front holding portion can be obtained. As a result, when gripping with an electric razor, the gripping property in a gripping state such as “holding a scissor” or “holding a grip” can be improved. As a result, a grip portion B that is hard to slip when used and is easy to use is provided. This eliminates the problem of slipping due to the pressing force when pressing against complex skin, not being able to shave with the optimum pressing force, or preventing the shaving blade (head part A) from hitting the skin at the optimum angle. There is an advantage that shaving time can be shortened by eliminating it.
[0037]
Further, in this example, since the non-slip portion 80 provided on the upper rear half portion B ₃ a of the grip portion B also functions as the operation portion of the trimmer, not only the grip performance but also the trimmer operability is improved. The upper portion of the front side of the front panel 60 At a position the thumb is placed during gripping, the slip portion 80 of the front B ₁ is being provided, the trimmer block 70, a slip preventing portion 80 of the front B ₁ slip portion 80 of the back B ₃ are arranged at substantially the same height. Accordingly, since the holding force of the thumb from the front B _1, the holding force of the index finger, middle finger from the back B ₃ are balanced, no longer need to grasp in all five fingers, gripping property is stable only in the thumb-index finger, middle finger . Further, thumb end joint by slip portion 80 of the front B ₁ on the front panel 60, non-slip portion 80 by the forefinger of the proximal phalanx, middle section of the back B ₃ trimer contacts the slip section 80, respectively. Furthermore by extending the slip portion 80 of the side B ₂ up to a front lower half section B _{1 b} of the grip portion B, since a slip preventing portion 80 was continuously disposed so as to go around the grip portion B, a front even when used by gripping the B ₁ and the back B ₃ in the reverse direction, for contacting the retaining portion 80 slip little finger or ring finger, a sufficient grip can be obtained. As a result, the gripping property at the time of gripping is improved, and the structure becomes more slippery during use and easier to use.
[0038]
Note In the above embodiment, the non-slip portion 80 was continuously disposed so as to go around the grip portion B, not necessarily limited to, continuous subjected at least the lower back from the side surface B ₂ halves B _{3 b} a is and what it is sufficient disposed in front upper half portion B _{1 a.}
[0039]
