Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to an electric shaver.

(B) Conventional technology Conventionally, an electric shaver that is provided with a U-shaped decorative frame and is engaged by winding the decorative frame around a gap between the main body case and an outer blade frame attached to the upper end of the main body case. Have been devised. For example, as disclosed in Japanese Patent Laid-Open No. 2-52693, a hole is formed in a decorative frame, and the button portion of the outer blade frame engaging member provided in the main body case is inserted into the hole to make the makeup. Some have a fixed frame. In this case, the decorative frame has to be mounted while pushing the button part inward of the case, which has a drawback that assembly workability is poor. Further, for example, as shown in Japanese Utility Model Publication No. 2-14744, a protrusion is formed on the tip of a U-shaped decorative frame, while a recess is formed on the decorative frame mounting portion of the main body case. There is one in which the protrusion is inserted into the recess.
In this case, in order to form the recess in the main body case, the molding die of the main body case is not complicated, and the protrusion easily comes out of the recess, and at this time, the decorative frame is broken, It has the drawback of being deformed.

(C) Problem to be Solved by the Invention The present invention has been made in view of the above points, and an object thereof is to provide an electric razor which is excellent in assembling workability and in which a decorative frame does not easily come off.

(D) Means for Solving the Problems The present invention is directed to a main body case, an outer blade frame provided at an upper end of the main body case, and a U-shaped makeup interposed between the main body case and the outer blade frame. The frame includes a frame, a frame body locked and fixed to the main body case, and an operation body arranged in the frame of the frame body and vertically movable along an inner wall of the frame body. The decorative frame has a pair of protrusions on opposite ends,
The said frame body solves the said subject by forming a pair of locking recessed part which fits and presses the protrusion part of the said decorative frame on the outer side wall.

(E) Action According to the present invention, since the locking recess for fitting and pressing the protrusion of the decorative frame is formed on the outer wall of the frame,
The protruding portion of the decorative frame does not come out of the locking recess, and as a result, the decorative frame does not come off.

(F) Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a main body case, in which a razor driving motor and a Ni-Cd battery (both not shown) as a power source are housed. A main blade drive shaft 2 projects from the upper end of the case 1, while a charging plug 3 for the Ni-Cd battery is slidably provided at the lower end.

Reference numeral 4 denotes an operating body, which is integrally formed with a switch operating plate 5 below and an accommodating portion 7 above which accommodates the knurled blade 6. Reference numeral 8 is a frame body that covers the side wall of the operating body 4. Thus, the operating body 4 has a first slide piece 9 below the side wall thereof, a second slide piece 10 above the side wall thereof, and a bifurcated elastic leg piece 11 at the lower end thereof. . On the other hand, an opening 12 is formed on the front surface of the main body case 1, and a moderation boss (not shown) that engages with and disengages from the bifurcated elastic leg piece 11 projects inward on the back surface. . Further, the frame 8 is provided with claws 13, 14, which are locked to the main body case 1,
15 is provided, and these claws are locked in locking holes 16, 17, 18 provided in the main body case 1. Further, the frame body 8 is formed with a slide wall 19 on which the second slide piece 10 slides.

Reference numeral 20 denotes a decorative frame, which is formed in a U shape and has a protrusion 21 formed at its tip. Also, 22
Is a locking recess formed on the outer wall of the frame body 8,
The protrusion 21 is inserted into the locking recess 22.

In the above configuration, the operation body 4 and the frame body 8
In order to attach the decorative frame 20 to the main body case 1, the bifurcated elastic leg piece 11 of the operating body 4 is attached to the opening 12 of the main body case.
From the first slide piece 9 and the opening part
Engage with the backside of 12 sidewalls. At this time, the bifurcated elastic leg piece
Numeral 11 is adapted to engage with the moderation boss. Next, the decorative frame 20 is slid and mounted from the direction opposite to the mounting surface of the operation body 4 of the main body case. After this, the claw 1 of the frame body 8
The frame body 8 is attached to the main body case by locking the 3, 14, and 15 into the locking holes 16, 17, and 18. At this time, the second slide piece 10 is positioned on the slide wall 19, and the protrusion 21 is inserted into the locking recess 22.

Here, if the switch operation plate 5 is moved up one step,
The bifurcated elastic leg piece 11 rides over the moderation boss due to its elasticity, and the first and second slide pieces 9 are formed.
And 10 slide on the back surface of the side wall of the opening 12 and the slide wall 19, respectively. At this time, the razor drive circuit is closed and the main blade is driven. When the cutting blade 6 is moved up one step further, the cutting blade 6 slides up and holds the rotationally protruding state, and the cutting blade 6 is driven.

Now, the first slide piece 9 and the second slide piece 10
Are slidably engaged with the back surface of the side wall of the opening 12 and the slide wall 19, respectively, so that an external force due to a drop or the like is applied to the knurled blade 6 in the protruding state of the knurled blade 6. In this case, the slide pieces 9 and 10 are prevented from falling and being damaged, and the slide pieces 9 and 10 are stably held.

Further, the locking concave portion 22 provided on the outer side wall of the frame body 8 locks the projection portion 21 formed at the tip of the decorative frame, and as a result, the decorative frame expands and comes off from the main body case. Prevent that.

(G) Effect of the Invention According to the present invention, since the locking recess for fitting and pressing the protruding portion of the decorative frame is formed on the outer wall of the frame body,
The protruding portion of the decorative frame does not come out of the locking recess, and as a result, the decorative frame does not come off.
