Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a device that displays to the user the switching between cutting and combing of hair cutters (electric hair clippers).

[Background technology]

There are hair cutters that can cut and cut, and hair cutters that adjust the cutting height with the blade tip.There are hair cutters that have a movable blade or a fixed blade that slides to change the cutting height or switch between skim and cut. The sliding amount of the blade is small (approx. 1mm to 2mm)
mm) It was difficult to judge the cutting height, gap, and cut by looking at the tip of the blade, and I sometimes ended up failing at a haircut by mistake.

Moreover, as shown in FIG.
Even in the case where the user slides the button to switch between clearing and cutting, the display is only displayed on the operating section 9, which is a handle that is operated with a finger. There was a problem that the display could not be enlarged and was difficult to see.

[Purpose of the invention]

The present invention has been made in view of the drawbacks of the conventional example described above, and its purpose is to compare the amount of movement of a display board indicating switching between skim cutting and cutting, etc. with the amount of slide of a switch handle. To provide a hair cutter switching display device which can make the display easier to see by enlarging the display.

[Disclosure of the invention]

(Structure of the Invention) The gist of the present invention is that a display board 4 is exposed through a window 2 opened in a housing 1 and displays the mowing state of the blade 3, and a switch handle 5 is used to switch the mowing state of the blade 3. A switching display device for a hair cutter, characterized in that the display board 4 is interlocked with the operation of a switch handle 5, and is provided with operation amount enlarging means for operating the display board 4 by expanding the amount of operation of the switch handle 5. It is in.

(Example) The blade 3 is a blade that can be switched between skiving and cutting, and is switched by moving a movable blade 6 back and forth with respect to a fixed blade 7. When the movable blade 6 is slid forward, it is used for cutting, and when it is slid back, it is used for mowing. An exploded perspective view is shown in FIG. 3, and the sliding (switching) of the movable blade 6 is caused by the forward and backward movement of the switch handle 5 being transmitted through the lever 10 and driver 11, and the switch handle 5 is moved forward (in the cut position). Then, the movable blade 6 moves forward to cut, and when the switch handle 5 is moved to the rear (skip-cutting position), the movable blade 6 moves back to the clearance-cutting position. The switch handle 5 is
A substantially inverted U-shaped lever operating surface 12 fits into a force point 13 at one end of the lever 10. An action point 14 opened in the shape of a long hole in the approximate center of the lever 10 fits into a post 15 of the driver 11, and a fulcrum 16 at the other end of the lever 10 rotates around a fulcrum receiver 17 of the housing 1. The force of the switch handle 5 is transmitted to the driver 11 to move the movable blade boss 18 fitted in the hole 17 of the driver 11 back and forth. The drive element 11 is pressed against the housing rib 20 by a presser spring 19 so as to be slidable. As shown in FIG. 5, the drive element 11 has an eccentric cam 23 attached to a motor 22 fitted into a slit groove 21, and the motor 2
2 is converted into horizontal movement of the driver 11, and the horizontal movement of the driver 11 is transmitted to the movable blade 6. On the other hand, a boss 24 is protruded from the switch handle 5, and the boss 24 is fitted with a rib 25 of the display plate 4, and the display plate 4 is moved along the front-rear axis of the switch handle 5 using the boss 26 of the housing 1 as a guide. Slide back and forth. The switch handle 5 has a "cut" position at the center, a "cut" position at the front, and a "open position" at the rear.As shown in FIG. It is indicated separately.

The stroke of the movable blade 6 is approximately 2 mm, and this stroke is expanded by the lever 10, so that the stroke is 4 mm at the force point 13 of the lever 10, and the stroke between the lever operation surface 12 of the switch handle 5 and the force point 13 is expanded. By providing a relatively large play between the switch handle 5 and the
A stroke of 4 mm is provided for each of "cutting" and "cutting → cutting".

In addition to the display next to the switch handle 5, the display board 4 displays "cut" and "skip" displays, and one of the displays is exposed through the window 2 of the housing 1. Moreover, display board 4
The operating amount is expanded by an operating amount enlarging means, so that when the switch handle 5 is slid by 4 mm, the display plate 4 is slid by 5 mm. That is, the click protrusion 29 at the end of the elastic leg 28 extending from the display panel 4 is brought into elastic contact with the enlargement operating section 30 provided on the inner surface of the housing 1.
0 has a width of about 5 mm and slopes 31 are formed on both sides, and play is provided between the boss 24 of the switch handle 5 and the rib 25 of the display board 4.

The operation of the display board 4 will be explained below. First, Figure 5 shows the switch handle 5 in the "off" position and the blade 3
is in the cut state, and the display board 4 also shows the "cut" state on the window 2 of the housing 1. Next, FIG. 6 shows a state in which the switch handle 5 is turned off from the state shown in FIG. 5, and in this state, the motor 22 is turned on. Due to the play between the lever operation surface 12 and the rib 25, the display plate 4 and the lever 10 do not move. Next, when the switch handle 5 is turned "off", the state shown in FIG. 5 is returned again. Next, FIG. 7 shows a state in which the switch handle 5 is set to the "open cutting" position. The power point 13 of the lever 10 is the switch handle 5
is moved rearward by the lever operation surface 12 (4 mm movement), and the point of action 14 is also moved rearward. Therefore, the boss 1 of the driver 11 which is fitted into the point of action 14
The movable blade 5 also moves rearward, and the movable blade 6 also moves rearward, resulting in a cutting state. On the other hand, boss 2 of switch handle 5
The rib 25 of the display board 4 that is fitted with the display board 4 also moves backward by 4 mm, but in this state, as shown in Figure 10a, the words "Suki-kari" on the display board 4 and the window 2 of the housing 1 do not match. The stroke is 1mm short. This shortage is made up of the click protrusion 29 of the display board 4.
is in the middle of the slope 31 of the expansion action part 30 of the housing 1, and due to the load of the elastic leg 28 bending, the slope 3
1 and move the missing part as shown in Figure 10b. Therefore, although the sliding amount of the switch handle 5 is 4 mm from "cut to clear cutting", the sliding amount of the display board 4 is 5 mm.
It is something that moves.

Next, the state shown in FIG. 8 is a state in which the switch handle 5 is returned to the "off" position from the open mowing state. On the window 2 of the housing 1, the words "Suki-kari" are displayed.

Next, when the switch handle 5 is set to "cut" from the state shown in FIG. 8, the lever 10 and the display board 4
moves, the blade 3 is set to the cutting state, and the display plate 4 moves forward by 4 mm to the state shown in FIG. 9a. In this state, the character "Katsuto" on the display board 4 and the window 2 of the housing 1 do not match, and the display board 4
The click protrusion 29 is in the middle of the slope 31 of the housing 1, and the click protrusion 29 slides down the slope 31 due to the bending load, and as shown in Fig. 9b, the stroke of the display plate 4 becomes 5 mm, and the housing 1
The characters ``cut'' on the window 2 and the display board 4 match. Note that the display cover 32 is transparent.

Since the present invention is configured as described above, the operating stroke of the display board displaying the mowing state can be made larger than the operation stroke of the switch handle, and the display (display characters) on the display board can be enlarged accordingly, allowing the user to determine the usage state. It has the advantage that it is easy to use and there is no risk of accidentally cutting hair.
