DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reciprocating electric shaver and, more particularly, to a reciprocating electric shaver having two blade heads arranged close to each other.

[0002]

2. Description of the Related Art In recent years, a reciprocating electric shaver provided with a plurality of blade heads has been provided. In this type, it is possible to shave at multiple places at the same time, but on the other hand, since there are multiple points of contact with the skin, as with a single blade head, If the player is allowed to move up and down only by providing play, the ability to follow the skin is poor, and the provision of a plurality of blade heads tends to be lost.

For this purpose, Japanese Patent Application Laid-Open No. 62-227395 proposes a device in which two blade heads rotate integrally. The rotation of the double blade head ensures that the double blade head always contacts the skin.

[0004]

However, even in this case, since only the blade heads can be individually moved up and down, the effect of squeezing and shaving the skin by a plurality of blade heads can be obtained. Despite not being able to fully pull out the skin and the nature of the skin varies widely depending on the user, the spacing between the blade heads is set to be almost constant, so that depending on the user, the distance between the blade heads may vary. There is dissatisfaction such as irritation due to large penetration of the skin, conversely, poor penetration of the beard due to small penetration of the skin, and a feeling of being applied to the skin being lumpy.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a reciprocating electric shaver in which two blade heads can follow a skin and perform good shaving. To offer.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a reciprocating electric shaver according to the present invention.
1 are arranged in parallel and parallel. As shown in FIG. 2, each of the blade heads 1 is configured such that an outer blade 12 bent in an arch shape is attached to a rectangular frame-shaped carrier 10, and the inside of a rectangular frame-shaped holding frame 15. And is attached to the main body 2 via the frame 18.

The carrier 10 is provided with a pair of locking holes 11 arranged at both ends in the longitudinal direction of the carrier 10 as support parts . Pins provided on the inner surfaces of both ends of the holding frame 15 in these locking holes 11 are provided. 162 are attached to the holding frame 15 by engaging. On the other hand, the holding frame 15 is attached to the frame 18 by locking the hooks 17 at both ends in locking recesses 180 provided on the inner walls at both ends of the frame 18, and the hook 1 provided with the push button portion is provided.
7 can be easily removed from the frame 18 by pushing it in. Two pairs of pins 162 are provided at both ends of the pair. The one located on the center side is provided on a connecting portion 161 that connects the tips of two pairs of left and right elastic pieces 160, 160 formed on the holding frame 15 and arranged in parallel in the vertical direction. The pin 162 located at the center can move up and down. A lever 19 slidable in the axial direction is attached to the center of the connecting portion 161 as shown in FIG. This lever 19 has a large diameter portion 19 arranged in the axial direction.
0 and a small diameter portion 191, and three holes formed in the hook 17 pass through the engagement holes 170 arranged vertically. In the drawing, reference numeral 193 denotes a retaining ring. Lever above
19, the engagement hole 170 and the connecting portion 161,
And the state in which the tilting is restricted.
The switching means for switching to is configured.

On the other hand, as shown in FIG. 6, a driver for converting the rotation of the motor into reciprocating motion is provided on the body 2 side, and a pair of drive bushes 43, 43 protruding from the driver.
Projecting from the upper surface of the main body 2, and the inner blades 13, 13 slidably contacting the inner surface of the outer blade 12 in each blade head 1, 1 are pushed up by drive bushes 43, 43 arranged in parallel and parallel, respectively, with springs (not shown). ) Are connected in a state where they are biased upward by (). As shown in FIG. 7, the inner blade 13 here is formed as a base 130 and a main body 132 mounted on the base 130 by a shaft 131, and the main body 132 tilts left and right. It is free. In addition, this tilting range is the stopper 133.
Limited by Reference numeral 7 in FIG. 8 is a switch handle.

When the small diameter portion 191 of the lever 19 is located in the engagement hole 170, the lever 19 and the connecting portion 161 are vertically movable with respect to the hook 17 and the holding frame 15. A pair of carriers 1 in the frame 15
When 0 and 10 are attached, both carriers 10 and 10 are
As shown in (1), they are arranged in parallel and parallel and without any inclination. However, when the inner blade 13 is brought into contact with the outer blade 12 by being attached to the main body 2, the inner blade 13 is pushed up by a spring force that pushes up the inner blade 13, so that as shown in FIG. The two blade heads 1 and 1 are tilted to the left and right with the pin 162 as the center to increase the interval between the two blade heads 1 and 1. And if you push the double-edged heads 1, 1 strongly against the skin,
Since the center pin 162 sinks, the interval between the two-blade heads 1 and 1 is reduced as shown in FIG. That is, by pressing against the skin, as shown in FIG.
The double-edged heads 1 and 1 sandwich the skin, and cause a beard by narrowing the skin to facilitate introduction of the beard. In particular, here, the outer blade 1 in each blade head 1, 1
Since the shapes of the inner and outer shapes 2 and 12 are set such that the inner radius of curvature adjacent to the other outer blade 12 is smaller than the outer radius of curvature, the skin narrowing effect is more remarkably exhibited.

When the large diameter portion 190 is positioned in the engagement hole 170 by pushing the lever 19, the lever 19
The vertical movement is regulated. At this time, if the vertical movement of the lever 19 is regulated at the upper end side of the engagement hole 170, the double-blade heads 1, 1 are fixed in the state shown in FIG. If the vertical movement of the lever 19 is restricted at the lower end side of the engagement hole 170, the state shown in FIG. 1B is fixed. As shown in FIG. 10, a user who has strong skin and desires a deeper shave should use the double-blade heads 1 and 1 with the distance between them widened. As shown in FIG. 11, the user may make the distance between the two blade heads 1, 1 narrow and use it in a form close to a single blade head 1.
