Description

[Detailed description of the invention] This invention relates to an electric hair clipper with an improved mounting method for the sliding operation knob of the drive switch.
The main focus is on improving the operability of the operation knob.

In the electric hair clipper shown in the drawing, a blade unit 4 is mounted at the front end of the main body case 1 in an upwardly tilted position.
At the same time, a mowing comb 13 that can be freely extended and retracted is installed above the cutting edge of the blade unit 4, and when mowing, grasp the main body case 1 and push the bottom side of the blade unit 4 in the forward upward tilting position. The main body case 1 is pressed against the head and pushed forward, and for plow cutting, the main body case 1 is turned upside down so that the plow cutting comb 13 is on the underside of the blade unit 4.

However, conventional electric hair clippers have main body case 1.
A sliding operation knob 19 is mounted only on one of the left and right side surfaces, generally the left side surface 20, and the drive of the movable blade 2 is turned on and off by sliding the operation knob 19 with the thumb of the right hand. The problem is this operation knob 19
This is the mounting position. Since the main focus is on the operability of the operation knob 19 during round mowing, when mowing with the body case 1 upside down or when a left-handed person performs circular mowing, the operation knob 19 can be used once with the thumb of the dominant hand. 19 and then change the main body case 1, or if not, slide the operating knob 19 with the index finger or middle finger, which is less convenient to operate than the thumb, which is extremely inconvenient.

Therefore, the purpose of this invention is to make it easier to slide the operation knob even when mowing the plow or for left-handed people.The main feature of this invention is that the electric clippers have a long length in the front and back direction. As a sliding operation knob for on/off operation of the power switch attached to the long box-shaped main body case,
The two left and right operation knob sections are connected together by a connecting plate, and the left operation knob section is attached to the left side of the main body case, and the right operation knob section is attached to the right side of the main case. It is arranged in an exposed manner so that the thumb and forefinger of the gripping hand can be placed on both the left and right operation knobs at the same time to slide the knobs, and the connecting plate has a display for displaying the usage status. The point is that it is a means.

Figures 1 through 7 show the first embodiment, in which the main body case 1 is made of upper and lower plastic cases 1a that are long in the front and back direction and are divided into upper and lower halves.

consists of a comb-shaped fixed blade 3 fixed to the upper surface of the fixed support 8 and a comb-shaped movable blade 2 fixed to the lower surface of the movable support 9 and slidably in contact with the upper surface of the fixed blade 3. This movable blade 2 is attached to a fixed blade support 8 with a support shaft 10.
A helical spring 11 attached through the fixed blade 3 is pressed against the upper surface of the fixed blade 3, and the fixed blade 3 slides back and forth in the left-right direction.
The fixed blade support 8 is removably attached to the lower surface of the front end of the lower case 1b in an upwardly tilted forward position. The movable blade 2 engages the arm 5a at the tip of the vibrator 5 with a hole 12 formed in the rear surface of the movable blade support 9, so that the rotation of the motor 6 is transmitted through the left and right reciprocating motion of the vibrator 5. It vibrates from side to side.

At the front end of the main body case 1, a plow comb 13 is installed above and near the cutting edge of the movable blade 2 so as to be movable forward and backward. In FIG. 7, this plow-cutting comb 13
In this example, plow cutting comb teeth 17 are formed at the tip of the handle 14, with shallow grooves 15 and deep grooves 16 arranged alternately in the left and right direction, and the comb teeth 17 are connected to the cutting edge of the fixed blade 3 and the upper case 1a. The gap between the front end of the upper wall 18 and the front end of the upper wall 18 can be changed stepwise in three steps in the front-rear direction, namely, a position with a small gap, a position with a large gap, and a circular cutting position.

The outer surface of the main body case 1 has a sliding operation knob 19 for turning on and off the drive motor 6 of the movable blade 2. In the illustrated example, the operating knob 19 also serves as an operating knob for moving the plow comb 13 in and out, but the present invention is characterized by the manner in which the operating knob 19 is attached.

In FIG. 6, the operation knob 19 is connected to the main body case 1.
A left operation knob portion 19a and a right operation knob portion 19b exposed on the outer surfaces of the left side surface 20 and right side surface 21, respectively, and left and right operation knob portions 19a on the inner side of the upper wall 18 of the upper case 1a, 19b and a connecting plate part 19c that integrally connects the left and right operation knob parts 19a, 19b and the connecting plate part 19c, each connecting part 19d, 19e connects the upper and lower cases 1a, 1b.

Indications such as "Less gap", "Large gap", "Off", and "Cut" are placed in order, and an instruction mark 26 colored on a part of the connecting plate 19c of the operating knob 19 is placed in the viewing window 25. Let me come. That is, the connecting plate portion 19c of the operation knob 19 is used as a display means for indicating the usage state by attaching the instruction mark 26.

When this happens, press the instruction mark 26 on the operation knob 19.
When is in the "off" position, the switch of the drive motor 6 of the movable blade 2 is in the off state, and the operation knob 19 is in the off state.
When the operator slides the instruction mark 26 backward from the character position of "cut" until it reaches the character position of "cut", the switch of the motor 6 is turned on and drives the movable blade 2, and as shown in FIG. As shown, the comb teeth 17 of the plow-cutting comb 13 are retracted backward from the cutting edge of the fixed blade 3, making round cutting possible.

When the operation knob 19 slides the instruction mark 26 forward from the character position of "OFF" until it reaches the character position of "SKI", the switch of the motor 6 is turned on and drives the movable blade 2. 7
As shown in the figure, the comb 13 protrudes forward,
Both the shallow grooves 15 and deep grooves 16 of the comb teeth 17 overlap with the cutting edge of the fixed blade 3, making it possible to perform more plow cutting. Further, when the operation knob 19 is advanced and stopped when the instruction mark 26 indicates the characters "low plow", the plow cutting comb 1 is moved as shown in FIG.
3, only the deep grooves 16 of the comb teeth 17 overlap with the cutting edge of the fixed blade 3, so that less plowing can be performed.

When performing this round cutting, as shown in FIG.
