Description

[Detailed Description of the Invention] This invention relates to an electric hair clipper having a unique method of attaching an attachment for aligning edges around the ears.

For example, when aligning the edges around the ears, it is necessary to cut only the relevant area to prevent careless hair cutting from other areas. Therefore, it is known from Japanese Utility Model Publication No. 52-39547 to cover one end of the cutting blade of the clipper while leaving the other end covered with a cap-shaped shutter member. However, since the conventional shutter member is removable from the clipper body, it is often easy to lose track of the shutter member during actual use, which is inconvenient.

Therefore, the first object of this invention is to integrally equip the clipper body with a trimming prevention device so that the user will not lose track of the location of the trimming prevention device. The second purpose is to improve the convenience of handling.

The details will be explained below based on the embodiment shown in the drawings. First, in FIGS. 1 and 2, 1
1 is a clipper main body 1 formed by connecting upper and lower cases 1a and 1b with their lids interlocked, and inside the boat-shaped lower case 1b, in order from the tip, there are a clipper blade unit 2, and a plastic vibrator 3 that drives the unit 2. , a motor 4 and a storage battery 5 are arranged respectively,
The upper case 1a is placed over the lower case 1b to form a long box shape as a whole.

The clipper blade unit 2 includes a fixed blade 7 integrated into a unit base 6, a movable blade 8 that slides back and forth on the upper surface of the fixed blade 7, and a movable blade support 9 that transmits the movement of the vibrator 3 to the movable blade 8. It consists of a spring 10 that presses the movable blade 8 against the fixed blade 7, and the lower end of the unit base 6 is removably supported on a support shaft 11 provided in the lower case 1b, and around the support shaft 11 with respect to the clipper body 1. to sway. In this attached state, both cutting edges 7a and 8a of the fixed blade 7 and the movable blade 8 protrude obliquely upward from the tip of the clipper body 1.

Inside the clipper body 1, there are a clipper blade unit 2,
A mowing prevention tool 12 is arranged between each member of the vibrator 3 and the motor 4 and the upper case 1a. This trimming prevention tool 12 includes a band-shaped shutter member 13 that prevents hair from entering the cutting blades 7a and 8a, and an operating member 14 that switches this between two positions: an operating position and a standby position (non-operating position). , and an engaging portion 15 that is held in each switching position. The shutter member 13 has a middle part supported by a U-shaped guide 16 integrated with the lower case 1b so as to be slidable back and forth, and a front end protruding from an opening 17 between the tip of the upper case 1a and the movable blade 8 to cut both sides. It moves in and out between an operating position in which the upper surfaces of the blades 7a and 8a are covered in a non-contact state and a standby position in which it retracts to the position of the opening 17. In the operating position, the tip of the shutter member 13 is the same as or slightly protrudes from the tip line of the cutting edge 7a of the fixed blade 7.
The horizontal width of the shutter member 13, that is, the area that covers both cutting edges 7a and 8a, is set so that a cutting area of about 10 mm remains on both sides of the shutter member 13. Shutter member 13
The corner 13a of the upper surface of the tip is finished with a curved surface to soften the contact with the ears.

The operating member 14 includes a box-shaped leg 18 connected to the rear end of the shutter member 13 and an operating knob 19 protruding from the upper surface of the leg. are exposed to the outside through an open operation window 20 in the upper case 1a, and are guided and supported so as to be freely movable back and forth, so that switching of the shutter member 13 is performed on the upper surface of the clipper body 1. Then, the engaging portion 15 extending from the rear end of the operating member 14 selectively engages with the engaging grooves 15a, 15a provided on the front and back of the inner surface of the upper case 1a, and the shutter member 13 and the operating member 14
are held at each switching position.

Reference numeral 21 in the figure is a switch that turns the motor 4 on and off.

In such a case, in normal use, the operation knob 19 is slid rearward as shown in FIG. 4, and the shutter member 13 is placed in a standby position in which it is retracted into the opening 17. When performing edge alignment, etc., slide the operation knob 19 forward to protrude the shutter member 13 from the opening 17, and use the shutter member 13 to cut the middle part of the upper surface of both the cutting edges 7a and 8a of the fixed blade 7 and the movable blade 8. The tip of the shutter member 13 catches the hair that tries to cover and enter the cutting blades 7a, 8a.

Note that by covering only the central portions of the cutting blades 7a and 8a with the shutter member 13 to provide cutting areas at each of the left and right side edges, it is possible to reverse the cutting direction of the clippers and perform cutting. You can easily align the surrounding edges from either the left or right, front or rear direction. Also, when cutting with one side of the cutting blades 7a and 8a, there is a risk of hair being cut off with the other side, but when aligning the edges, use the clippers with the clippers held almost perpendicular to the skin. Therefore, your hair will not get caught in there, and even if there is an unexpected movement of the clippers or your head, there will be enough space to prevent your hair from being accidentally cut off.

FIG. 5 shows another embodiment of the present invention, in which the shutter member 13 and the operating member 14 are formed separately, and the shutter member 13 is supported so as to be movable in the left and right directions with respect to the operating member 14. It has become a thing. Specifically, the operation member 14 is provided with left and right horizontally elongated holes 22, and two
A book pin 23 is guided and supported, and an operating knob 24 is provided protruding from the upper surface of the shutter member 13, and the knob 24 is made to face the upper surface of the upper case 1a. In addition, the operating member 14
Operation knobs 19 are provided on the left and right sides of the clipper body 1, and are supported on the left and right side walls of the clipper body 1 so as to be slidable back and forth. The protruding bifurcated connecting portions 15 are elastically engaged to hold the operating member 14 in the forward/backward switching position.

By making the shutter member 13 horizontally movable in this way, the cutting area L of the cutting blades 7a and 8a can be switched left and right with a single touch, depending on the direction of cutting progress of the clippers during alignment, and the cutting area L can be changed with a single touch. It is convenient because the left and right width of L can be adjusted arbitrarily.

FIG. 6 shows yet another embodiment of the present invention,
In this case, the shutter member 13 is arranged on the upper surface of the upper case 1a, and its front base end is rotatably supported via the shaft 25, and the shutter member 13 is placed in the operating position and the standby position by rotating around the shaft 25. It is designed so that it can be switched. In this way, the attitude switching means for the shutter member 13 can be changed as necessary.

Further, in addition to the above, the tip of the shutter member 13 may be formed into a hook shape when viewed from the side so that it also covers the lower surface side of the cutting edge 7a of the fixed blade 7 in the operating position.

As explained above, in this invention, both the cutting edges 7a and 8a of the fixed and movable blades 7 and 8 are
By covering the upper surface of the hair, both cutting blades 7a, 8
Since the shutter member 13 is prevented from entering the clipper body 1, it is possible to support the shutter member 13 so that it can be easily switched between the operating position and the standby position with respect to the clipper body 1. Therefore, when aligning the edges around the ears, etc., by immediately switching the shutter member 13 to the operating position, it is possible to prevent unnecessary hair cutting and put the shutter member 13 into the alignment operating state. It is sufficient to simply switch the member 13 to the standby position, and the location of the shutter member 13 will not be lost.

Furthermore, since the shutter member 13 covers the cutting area with cuttable areas provided at both ends, it is possible to reverse the cutting direction of the clippers and cut, making it easy to align the edge around the ears from either the left or right or front or back direction. can be done.
