DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trimmer device for an electric shaver that can move the trimmer blade, which is normally placed along the body of the electric shaver, to a position suitable for the purpose of use.

Conventionally, this type of trimmer block has been provided with a trimmer block mechanism provided on an outer cutter frame attached to the main body housing.

For this reason, the trimmer portion obstructs attachment and detachment of the outer cutter frame, making it difficult to attach and detach, and the outer cutter frame becomes very large, causing problems in terms of appearance. Furthermore, when the outer cutter frame is removed to clean the beard shoulders that have accumulated inside, there is a possibility that the outer cutter frame will be dropped, and at this time there is a risk that a part of the trimmer may be damaged. The present invention has been made in view of these points, and its purpose is to not only make it easy to attach and detach the outer cutter frame, but also to make the outer cutter frame small so that the external appearance is not impaired. is to provide electric razor trimmer equipment.

Therefore, the present invention provides a main body housing whose upper end edge is a mounting base for an outer cutter frame that holds an outer cutter in a main cutter consisting of an inner cutter and an outer cutter, and a guide groove provided on one surface of the main cutter. a trimmer block rotatably supported on the moving plate so as to be movable up and down along the main body housing, and equipped with a trimmer blade on the top green; It consists of an operation panel that controls the rotation of the trimmer block and the vertical movement of the moving plate and trimmer block, and a power transmission mechanism that transmits power both to the trimmer flock during rotation and to the trimmer block during shift. The trimmer block can be rotated from the main body housing, and the trimmer blade can be used alone with the trimmer blade separated from the outer blade at the upper end of the main body housing, and the trimmer block can be moved upward along the main body housing. The use of the trimmer blade in close proximity to the king blade at the upper end of the main body housing, that is, the interlocking use of the main blade and trimmer blade, can be selected by operating a single operation panel. In addition, the moving plate to which the trimmer flock is attached is supported by the main body housing.The present invention will be described in detail below with reference to the illustrated embodiments.

The trimmer block 2 is rotatably supported, and one end of the trimmer block 2 is attached to the trimmer block 2, and the spring 6 is fixed to the moving plate 3 and is housed in the spring arrangement space 34. In other words, the trimmer flock 2 attached to the moving plate 3 is biased in the direction of fitting into the opening row 1 for installation.
passes through the back of the moving plate 3 and projects downward. This engaging protrusion 28 can freely engage with the holding protrusion 48 of the operating plate 4 and the teeth of a star-shaped gear 5 provided within the main body housing. The gear 5 is rotatably mounted on a shaft 7 installed in the main body housing 1 in the horizontal direction. A leaf spring 59 is slidably supported and attached to a long engagement groove 19 and is located on the back side of this shaft 7 and supported by the leaf spring support piece 20' of the main body housing 1. The shaft 7 is biased toward the front side, and the shaft 7 is freely movable against the leaf spring 59 toward the rear side as indicated by the arrow in FIGS. 2 and 7. The gear 5 is rotatably attached to the shaft 7 constructed in this manner, and one surface thereof engages with a tooth surface 53 of a fixed ratchet wheel 52 attached to the shaft 7 in the same manner as the gear 6. An engaging tooth surface 51 is provided. Fixed ratchet wheel 5

One pin 55 is arranged in a pin groove 57 provided on the opposite side of the engaging tooth surface 53 to prevent the fixed ratchet wheel 52 from rotating. Both engaging tooth surfaces 51 are engaged by a pressing spring 54 whose one end is in elastic contact with the other pin 55 and the other end is in elastic contact with the gear 5
, 53, one surface of each tooth is a vertical surface and the other surface is an inclined surface, and the gear 5 is shown by an arrow in FIGS. 5 and 6 relative to the fixed ratchet wheel 52 fixed to the shaft 7. It is designed so that it can only rotate in one direction. Next, the operation will be explained.

FIG. 2 shows the off state, and from this state, the power slide switch 40 disposed in the slide hole 43 provided in the operation part 41 of the operation panel 4 is moved to the center lock plow 39.
When the motor 61 is pressed and slid to the right in the figure, the motor 61 is energized, and the inner cutter 65 is driven via the main driver 64. At this time, the trimmer drive element 25 whose one end protrudes from the lower part of the trimmer block 2 toward the back side is located below the main drive element 64 and is not connected to the fixed blade 22 and the movable blade 2.
The trimmer blade 21 consisting of 3 is not driven.
From this state, push the operation part 41 of the operation plate 4 into the recess 4.
When the upper part is bent from 9, the presser projection 48 on the upper end of the operation plate 4
is an engaging protrusion 28 that hangs down from the trimmer block 2.
Push to the back side to rotate the trimmer flock 2 against the spring 6. Further, by pushing the operating part 41, the engagement protrusion 28 of the trimmer flock 2 comes into contact with the star-shaped gear 5, which is moved forward by the leaf spring 59.
This gear 5 is rotated. When the trimmer flock 2 begins to open from the main body housing 1 to a certain position, the engaging tooth surface 51 of the gear 5 seats on the engaging tooth surface 53 of the fixed ratchet wheel 52 and a ratchet engagement sound is obtained. If you release your hand, the operation plate 4 will return to its original position due to its own elasticity, but the trimmer flock 2 will not be able to reverse its rotation due to the engagement protrusion 2 on the gear 5.
8 remains engaged, so the opened state is maintained. In the trimmer flock 2 opened in this way, the trimmer driver 25 is connected to the main driver 64 as shown in FIG. 7, and the movable blade 23 starts reciprocating vibration. To return the trimmer lock 2, the operation plate 4 may be pushed in again. The holding protrusion 48 of the operation plate 4, which is pushed in deeper than when opening the trimmer flock 2, presses the gear 5 instead of the engagement protrusion 28 of the trimmer flock 2, as shown by the imaginary line in FIG. This gear 5 is moved backward together with the shaft 7. As a result of this retreat, the engagement protrusion 28 and the gear 5 are disengaged, and the trimmer flock 2 is returned to its original position under the bias of the spring 6. After the operation plate 4 and trimmer flock 2 return, the gear 5 that has moved backwards,
It is returned to its original state by a leaf spring 59. Furthermore, this trimmer flock 2 can also be operated by moving the operation plate 4 upward.
5 is connected to the main drive element 64 to drive the trimmer blade 21. When the operation plate 4 is slid upward, the trimmer block 2 is pushed up together with the moving plate 3 sliding up the guide groove 14, and the trimmer driver 25 is connected to the main driver 64 as shown in FIG.
At this time, the trimmer block 2 does not open and operates with the trimmer blade 21 close to the outer blade 17. Even if an attempt is made to push the operation plate 4 in this state, the trimmer block 2 will not open because the engagement piece 28 assists the main driver 64. To return to this state, slide the operation plate 4 downward. Since the moving plate 3 is pulled down by the engaging piece 47 engaged with the recess 35 of the moving plate 3, the trimmer lock 2 returns to its original position. The space below the moving plate 3 in the wide part of the mounting opening 11 caused by the upward movement of the trimmer block 2 and the moving plate 3 is filled with the cover plate 46 of the operation plate 4, so that no gap is created. As described above, in the present invention, the trimmer block can be rotated from the main body housing, and the trimmer blade can be used alone in a state where it is separated from the outer blade at the upper end of the main body housing, and the trimmer block can be moved up along the main body housing. Using the trimmer blade while moving it close to the main blade at the top of the main housing, that is, after cutting with the trimmer blade,
Furthermore, the main blade is suitable for cutting the tips of long beards, and the interlocking use of the main blade and the trimmer blade can be selected by operating a single operation panel. The trimmer blade can be used differently depending on the situation, and the operation for different uses can be performed only with the operation panel, and there is no material needed to move the trimmer block. are all provided in the main body housing, and the outer cutter frame attached to the outer cutter frame mounting base at the upper end of the main body housing only has to perform its original function of holding the outer cutter. Not only is the outer cutter frame easy to attach and detach, but it is also small and there is no risk of damaging the trimmer section when the outer cutter frame is removed.
