Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a reciprocating electric shaver in which an outer blade is mounted via a carrier.

2. Description of the Related Art Since the outer blade of a reciprocating electric shaver is a consumable item, it has to be considered in consideration of replacement at the time of consumption. And, in the conventional reciprocating electric shaver, the outer blade was configured to be directly attached to and detached from the outer blade frame, but in the case where the outer blade is made of a thin metal plate with a blade hole, the outer blade is Since the outer blade is often damaged when it is attached to the frame, it is often assumed that the outer blade is attached to the carrier and that the outer blade is replaced for each carrier. Is shown in FIG. In the figure, 4 is an outer blade frame, 3 is a carrier, and both ends of the outer blade 1 are attached to the carrier 3 by attachment plates 6. The carrier 3 is provided with engaging portions for both ends of the outer blade frame 4, and when the attachment / detachment buttons 31 provided at both ends of the carrier 3 are pushed in, the engagement with the outer blade frame 4 is released. It is designed to be removable.

[Problems to be solved by the device]

Here, the carrier 3 is to disengage the carrier 3 from the outer cutter frame 4 when the detachable button 31 is pushed in. Therefore, the detachable button 31 is attached to the outer surface of the outer cutter frame 4 when it is not pushed in. Has a large protrusion, and the design is bad. Further, the cap 9 for protecting the outer blade 1 does not need to be provided with the groove 90 or the cover portion 91 as shown in FIG. 6 in order to prevent the attachment / detachment button 31 from being caught. It doesn't happen, and it can't have a clean design. The present invention has been made in view of such a point, and an object thereof is to provide a reciprocating electric razor capable of having a neat design without impairing the attaching / detaching function of the outer blade by the carrier. is there.

[Means for Solving the Problems]

Therefore, the present invention provides a reciprocating electric shaver, which comprises a carrier having an outer blade attached thereto, wherein the outer blade is attached to the outer blade frame via the carrier detachably attached to the outer blade frame, The carrier is provided with hooks and detachable buttons at both ends thereof, and the outer blade frame is provided with locking pieces with which the hooks are engaged in mounting grooves formed in the walls at both ends thereof and opened in the removing direction of the carrier. It is characterized in that the outer surface of the wall is provided with a recess located around the detachable button of the carrier. [Effect] According to the present invention, since the outer cutter frame has a recess, the stroke required to disengage the hook of the carrier from the locking piece is achieved without the attachment / detachment button protruding significantly from the outer cutter frame. It can be attached to a detachable button. [Embodiment] The present invention will be described in detail below with reference to the illustrated embodiment. This reciprocating electric shaver has a main body 8 having a switch handle 80 on a side surface, and a main body 8 protruding from an upper end of the main body 8. An outer blade frame 4 formed in a fine shape, and an outer blade 1 detachably attached to the outer blade frame 4,
The outer blade 1 is provided with a cap 9 for protection, the outer blade 1 is detachably attached to the outer blade frame 4 via the carrier 3, and the cap 9 has the same thickness and width as the main body 8. When the outer blade frame 4 is covered with the cap 9, the outer surface of the main body 1 and the outer surface of the cap 9 are continuous without a step. 2 in FIG. 2 is an inner blade composed of an inner blade base 21 and a plurality of blades 20 attached thereto, 5 is a driver for reciprocating the inner blade 2, and 50 is incorporated in the driver 5. Is a push-up spring that pushes up the inner blade 2 toward the outer blade 1. The outer blade frame 4 is provided with mounting grooves 42 that are also opened upward in the walls at both ends thereof, and the mounting grooves 42
It is provided with a locking piece 40 projecting inward, and the outer blade 1 is attached by a mounting plate 6 that locks the mounting piece 60 to the carrier 3.
The carrier 3 having both ends attached thereto is attached to the outer blade frame 4 by engaging the hooks 30 provided at both ends thereof with the engaging pieces 40. Also, the carrier 3 is integrally provided with elastic arm type attach / detach buttons 31 which are located outside the hook 10 at both ends thereof, as in the above-mentioned conventional example. The carrier 3 can be removed from the outer blade frame 4 because the bending of the inner portion 30 causes it to disengage from the engagement state with the locking piece 40. At this time, both ends of the outer blade frame 4 can be removed. A recess 41 is formed on the outer surface of the wall surrounding the detachable button 31.
Since the stroke of the detachable button 31 can be increased by the depth of the recess 41 when pushing in 31, the detachable button
The amount of protrusion of 31 to the outer surface of the outer blade frame 4 is kept small, so that the presence of the attachment / detachment button 31 does not cause a design failure. Further, the attachment / detachment button 31 here has an inclined surface that spreads outward toward the lower side, like the outer surface of the outer cutter frame 4, so that when the cap 9 is covered, even if it is covered diagonally, The cap 9 is designed to ride over the removable button 31 without being caught by the button 31. Incidentally, here, when the cap 9 is covered, the detachable button 31 is also completely covered with the cap 9. FIG. 4 shows that the recess 41 provided on the outer surface of the outer cutter frame 4 is extended to the upper end along the mounting groove 42 so that the carrier 3 can be removed more easily.

[Effect of device]

As described above, in the present invention, since the recess provided in the outer cutter frame is around the detachable button, the hook of the carrier can be disengaged from the locking piece without the detachable button being largely projected from the outer cutter frame. The necessary stroke can be given to the attachable / detachable button. Therefore, the projecting amount of the attachable / detachable button can be suppressed and the design can be improved without deteriorating the operability for detaching the carrier.
