Description

[Detailed Description of the Invention] This invention relates to a safety razor in which a replaceable blade accommodating member is swingably attached to the tip of a holder.

Conventionally, as a prior art of Koha species, it was developed in 1983.
There is number 105070. In this safety razor, as shown in FIGS. 1 and 2, a replaceable blade housing member 3 is supported so as to be tiltable in the front and rear directions with respect to both support arms 2 which are provided at the tip of a holder 1 so as to be openable and closable. The tip of the pusher 4, which is biased to protrude from the tip of the pusher 1, is in contact with the contact surface 5 of the replaceable blade housing member 3. When the replaceable blade accommodating member 3 is tilted forward as shown in FIG. Then, the replaceable blade housing member 3 becomes the most forwardly inclined state. On the other hand, when the disposable blade housing member 3 for shaving is tilted backward as shown in FIG. The replaceable blade housing member 3 is brought into the final tilted state. That is, the replaceable blade housing member 3 can swing back and forth within a certain tilt angle range against the biasing force of the pusher 4.

In the safety razor configured as described above, in the most forward tilted state shown in FIG. Since the distance between the tip of the pusher 4 and the contact position B is increased, the replaceable blade housing member 3 is supported with good stability, and the movement of the replaceable blade housing member 3 is not so loose. Also, when you press the replaceable blade housing member 3 against your skin at the beginning of shaving, the elasticity of the pusher 4 has almost no effect on the replaceable blade housing member 3, and after that the blade housing member 3 is pushed down and the beard is actually removed. When shaving, the elasticity acts on the disposable blade housing member 3 only after the blade housing member 3 tilts backward against the biasing force of the pusher 4. Therefore, at the beginning of shaving, the replaceable blade housing member 3 lacks flexibility, resulting in a poor shave.

The purpose of the present invention is to slightly loosen the movement of the blade housing member in the most forward tilted state by improving the stopper means when the blade housing member is tilted forward by the biasing force of the pusher. To provide a swingable safety razor which can give flexibility to a replaceable blade housing member by slightly utilizing the elasticity of the pusher even at the beginning of shaving.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 and 4, focusing on the differences from the conventional example described above. When the replaceable blade housing member 3 is tilted forward as shown in FIG. 3 due to the urging force of
A stopper protrusion 8 that abuts the lower surface of the bent portion 4a below the abutting position with the abutting surface 5 is provided on the replaceable blade accommodating member 3 close to the abutting surface 5. That is, in the most forward tilted state, the replaceable blade housing member 3
is supported by the pusher 4 at two points A and B, and the distance between the contact position A of the stopper protrusion 8 and the contact position B of the tip of the pusher 4 becomes small. Therefore, the support of the replaceable blade housing member 3 becomes unstable, and its movement becomes slightly loose. Also, when the replaceable blade housing member 3 is pressed against the skin at the beginning of shaving, the pusher 4 resists the biasing force and slightly presses through the stopper protrusion 8 and the lower surface of the bent portion 4a of the pusher 4. When pushed, the elasticity of the pusher 4 acts on the replaceable blade housing member 3. Therefore, the flexibility of the replaceable blade housing member 3 is improved at the beginning of shaving.

After that, when pushing down the replaceable blade housing member 3 to actually shave, the stopper protrusion 8 separates from the lower surface of the bent portion 4a of the pusher 4, and the replaceable blade housing member 3 resists the biasing force of the pusher 4. As shown in FIG. 4, the blade accommodating member 3 is tilted backward so that the stopper protrusion 7 on the upper side of the blade accommodating member 3 comes into contact with the upper surface of the tip end of the holder 1.

As described in detail above, the present invention provides a replacement blade housing member 3.
When is tilted forward by the urging force of pusher 4,
Contact surface 5 between the tip of the pusher 4 and the replaceable blade housing member 3
Since the stopper protrusion 8 that contacts the lower surface of the pusher 4 below the contact position with the blade is provided on the replaceable blade housing member 3 in close proximity to this contact surface 5, This has the effect of improving the flexibility of the replaceable blade housing member 3 and improving the shaving quality.

Claims (1)

[Claims for Utility Model Registration] 1. A replaceable blade storage member 3 is supported so as to be tiltable in the front and rear directions with respect to a support arm 2 provided at the tip of the holder 1, and is biased to protrude from the tip of the holder 1. The replaceable blade housing member 3 is provided with a contact surface 5 on which the tip of the pusher 4 contacts, and the replaceable blade housing member 3 is swung back and forth within a certain tilting angle range against the biasing force of the pusher 4. In this safety razor, when the replaceable blade housing member 3 is tilted forward by the urging force of the pusher 4, the tip of the pusher 4 is lower than the abutment position of the contact surface 5 of the replaceable blade housing member 3. The stopper protrusion 8 that comes into contact with the lower surface of the pusher 4 is placed close to the contact surface 5 of the replaceable blade housing member 3.
A swingable safety razor characterized by the following features: 2. The tip portion of the pusher 4 is bent upward obliquely, and the stopper protrusion 8 of the replaceable blade housing member 3 comes into contact with the lower surface of this bent portion 4a.Claim 1 of Utility Model Registration: Oscillating safety razor as described in section.
