Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric shaver with trimmer blades, and more particularly to an electric shaver with trimmer blades in which the trimmer blades protrude outward during use.

Conventionally, in this type of electric shaver where the trimmer blade protrudes outward during use, the trimmer blade protrudes outward by the switch handle that turns the power on and off, and the trimmer blade can only be operated when the trimmer blade is driven. Therefore, if you use a brush to clean with the trimmer blade sticking out, the tips of the brush bristles will be cut off by the trimmer blade, making it difficult to clean. There was a problem.

The present invention has been made in view of the above points, and its main purpose is to be able to hold the trimmer blade in a position where it protrudes outside the housing without driving the trimmer blade, and in this state, the trimmer blade can be held in a position where it protrudes outside the housing. The trimmer operating handle can be operated independently of the switch handle that turns the motor on and off, and the trimmer operating handle can be operated in close proximity to the switch handle without damaging the bristles of the brush used for cleaning. Even though the blade handles are arranged so that both handles can be easily operated with one finger, there is a risk of accidentally moving the trimmer operating handle and driving the trimmer blade while operating the switch handle. There is no trimmer blade to offer.

The present invention will be described in detail below based on embodiments shown in the figures. The electric shaver with trimmer blades according to the present invention includes:
A housing 1 from which an inner cutter 3 driven by a motor 2 projects upward; an outer cutter frame 5 that is attached to the upper end of the housing 1 and holds an outer cutter 4 that extends along the inner cutter 3; and a part of the housing 1. A trimmer blade block 6 is attached to the housing 1 so as to be able to freely protrude outward, and one end is connected to the trimmer blade block 6 to allow the trimmer blade block 6 to be retracted into the housing 1 and protrude outward. a trimmer lever 8 that moves between two positions within the housing 1 to switch between positions;
and a switch handle 7 that slides along one outer surface of the housing 1 and stops at two operating positions: a stop position where the motor 2 is stopped and a drive position where the motor 2 drives the inner cutter 3; These handles are arranged side by side on the outer surface of the housing 1, and slide at a position close to the switch handle 7 on an extension line in the sliding direction of the switch handle 7, and move the trimmer lever 8 to move the trimmer blade block 6 to the housing 1. A trimmer operating handle 9 that stops at two operating positions: an open position in which the trimmer blade block 6 is projected outward and a closed position in which the trimmer blade block 6 is retracted; 6 movable blades 10
The switch handle 7 and the trimmer are connected to a cam 28 which converts the rotational operation of the motor 2 into a reciprocating motion of the movable blade 10 and is disconnected from the movable blade 10 when the trimmer blade block 6 is retracted. The trimmer operating handle 9 is displaceable independently of the operating handle 9, and the trimmer operating handle 9 is held in this stop position by a locking means 50 provided on the trimmer operating handle 9 in the above-mentioned closed position. be.
In this embodiment, as shown in FIGS. 1 to 3,
A trimmer operating handle 9 and a switch handle 7 are disposed above and below the front surface of the housing 1, and a trimmer blade block 6 is attached to the rear surface of the housing 1, and the trimmer moves up and down within the housing 1 in conjunction with the trimmer operating handle 9. This shows an example in which the trimmer blade block 6 protrudes outside the housing 1 when the trimmer operating handle 9 moves upward via the operating plate 12 and the trimmer lever 8 rotating within the housing 1. The housing 1 is formed by combining two halves 11, 11 into a substantially T-shape with a wide upper part, and a portion below the wide part 13 serves as a handle part. The trimmer operating handle 9 and the switch handle 7 are arranged vertically on the outer surface of the upper end of the handle portion of one half body 11, respectively, and as shown in FIGS. 5 and 6, the trimmer operating handle 9 and the switch handle 7 The handle 9 has a locking claw 1 protruding from the back surface.
5 into the locking hole 16 of the trimmer operation plate 12 in the housing 1, and open the opening 17 of one half body 11.
The switch handle 7 is arranged so that it can move up and down.
The trimmer operation handle 9 is attached to the concave step 14 below the opening 17 by inserting the locking pawl 18 protruding from the back surface into the locking hole 21 of the switch board 20 in the housing 1 through the slit 19 so as to be vertically movable. The switch handle 7 and the switch handle 7 are configured to slide along a vertical straight line within the same plane. The switch board 20 moves up and down in conjunction with the switch handle 7, and has a sawtooth part 22 formed on both sides of the back surface with two valleys lined up in the vertical direction. The switch handle 7 is given a click property so that the switch handle 7 is stopped at a position where the ball 24 disposed at the position is pressed against the sawtooth part 22 by a spring 25, and the ball 24 is accommodated in each valley part. A movable contact 26 extending from the switch board 20 slides on a fixed contact (not shown) fixed at a fixed position within the housing 1 to turn on and off the power to the motor 2. That is, the motor 2 is stopped at the lower position of the switch handle 7 that moves in two stages (up and down), and the motor 2 is driven at the upper position, and is connected to the output shaft 27 of the motor 2 via the eccentric cam 28 and the driver 29. By reciprocating the inner cutter block 30 on the blade holder 31, the inner cutters 3 arranged in parallel on the inner cutter block 30 slide along the lower surface of the outer cutter 4 of the outer cutter frame 5, and the outer cutter The beard captured by the beard introduction hole in step 4 is shaved. On the other hand, the trimmer blade block 6 has a storage recess 33 provided on the outer surface of the wide part 13 of the half body 11, which is different from the half body 11 to which the trimmer operation handle 9 and the switch handle 7 are attached.
The arms 34, 34, which are housed in the storage recess 33 and which are pivotally supported on both sides of the upper end to the half body 11 and project on both sides of the upper end, are inserted into the through holes 35, 35 at the bottom of the storage recess 33.
A trimmer lever 8 is mounted so as to protrude into the housing 1 through the trimmer lever 8 and rotates within the housing 1.
As a result, the trimmer blade block 6 rotates using its rear end as a fulcrum and protrudes from the storage recess 33. The trimmer lever 8 is formed into a substantially U-shape as shown in FIG.
The housing 1 is pivoted on a bearing 38 provided on the inner surface of the housing 1.
It can be rotated freely around the horizontal axis within the
Connecting pins 39, 39 protruding from the tips of a, 8a are connected to arms 34, 34 of the trimmer blade block 6, respectively. On the other hand, the trimmer operation plate 1 moves up and down together with the trimmer operation handle 9 within the housing 1.
At the upper end of 2 are projections 40, 4 for abutting against the body piece 8b of the trimmer lever 8 and pushing it upward.
0 is provided, and as shown in FIG. 7, when the trimmer operating handle 9 is pushed upward, the protrusion 4
0 pushes up the body piece 8b of the trimmer lever 8 and rotates the trimmer lever 8 around the pivot pin 37, thereby rotating the trimmer blade block 6 in the direction shown by the arrow in the figure and causing it to pop out from the storage recess 33. That's why. Here, the pivot pin 37 and the bearing 3
A torsion coil spring 41 is interposed between the trimmer blade block 6 and the trimmer lever 8. When the operating handle 9 is moved from the open position to the closed position, the trimmer blade block 6 automatically returns to the storage recess 33 from the protruded position. To perform a close shave using the trimmer blade block 6, push up the switch handle 7 to the upper position to drive the motor 2 as shown in FIG. In this way, the trimmer blade block 6 is made to protrude outside the housing 1, and at this time, the engagement protrusion 44 protruding from the rear end of the movable element 43 of the trimmer blade block 6 engages with the engagement recess of the drive element 29 which is being reciprocated. 45 to move the movable blade 10 held by the movable element 43 to the fixed blade 4.
6 and is driven back and forth. Incidentally, a pair of elastic arms 52 having protrusions 51 at their tips protrude from the upper ends of both sides of the trimmer operation plate 12, and constitute the locking means 50.
As shown in FIG. 9 and FIG. 9, the trimmer operating plate 12
The protrusion 51 is adapted to stop. That is, when the trimmer operation handle 9 is lowered to the closed position, the locking pawl 15 comes into contact with the lower edge of the opening 17 and the elastic arm 52 The projection 51 at the tip of the trimmer blade block 6 presses against one side of the protruding rib 54 to hold the trimmer operation plate 12 and the trimmer operation handle 9 in the closed position where the trimmer blade block 6 is retracted, and the trimmer operation handle 9 is moved upward from this closed position. When pushed up, the protrusion 51 bends the elastic arm 52 and the protruding rib 54
As shown in FIGS. 8c and 9b, the protrusion 51 comes into pressure contact with the protruding rib 54, and the locking pawl 15 comes into contact with the upper edge of the opening 17, thereby removing the trimmer operation plate 12 and the trimmer. The operating handle 9 is held in this position, that is, the open position in which the trimmer blade block 6 protrudes outward, and the trimmer operating plate 12 is held in the above two positions until the trimmer operating handle 9 is operated next. be done. Further, as shown in FIG. 8b, even when the switch handle 7 is moved upward to the driving position for driving the inner cutter 3, the locking member 18 is locked to the upper edge of the slit 19. The upper end of the switch handle 7 is separated from the trimmer operating handle 9 in the closed position, so that the trimmer operating handle 9 is not moved by the movement of the switch handle 7, and both handles 7,
9 are operated independently of each other. Next, when cleaning the trimmer blade block 6, the trimmer operating handle 9 can be moved independently of the switch handle 7, so as shown in FIG. 8d, the switch handle 7 is moved to the lower stop position. When the trimmer operation handle 9 is pushed upward in the lowered state, the trimmer lever 8 rotates as described above, the trimmer blade block 6 protrudes outside the housing 1, and the trimmer operation plate 12 and the trimmer operation handle 9 are moved to this open position. In this state, the drive element 29 is not driven, and the movable blade 10 of the trimmer blade block 6 is kept stationary, and the beard debris adhering to the trimmer blade block 6 is removed using a brush or the like. It is something that can be done.

As described above, the present invention allows the switch handle and the trimmer operating handle to be displaced independently of each other,
Since the trimmer operating handle is held in this open position by the locking means provided on the trimmer operating handle, the trimmer blade block can be projected out of the housing while the trimmer blade is stopped driving. As a result, when using the brush to remove beard debris attached to the trimmer blade block, the bristles of the brush are not damaged and the trimmer blade block can be easily cleaned. This has the advantage that, even though the switch handle and the trimmer operating handle are arranged in a straight line and both handles can be easily operated with one finger, both handles can be displaced independently of each other. This has the advantage that there is no risk of the trimmer operating handle being moved by mistake and the trimmer blade block being inadvertently protruded by moving the switch handle.
