Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a safety razor in which a blade is supported so as to be tiltable in the width direction thereof.

[Prior Art] Conventionally, a safety razor in which a blade is supported so as to be tiltable in the width direction thereof has been developed.

In this type of safety razor, depending on the preference of the user, there is a case where the blade body is desired to be tilted in the width direction and a case where it is desired to use it without tilting.

[Problems to be Solved by the Invention] However, in the past, there was no locking means for making the blade body inclinable in the width direction.

Therefore, it is an object of the present invention to provide a safety razor having a locking means capable of stably holding the blade body in a tiltable state when it is desired to use the blade body in a tiltable manner in the width direction according to the preference of the user.

[Means for Solving the Problems] In order to solve the above-mentioned object, in the present invention, the blade mounting member is supported with respect to the handle so as to be tiltable in the width direction of the blade mounted to the blade mounting member. At least one of the blade attachment member and the handle is provided with a locking portion, and the other is provided with a lock member engageable with the locking portion, and the locking member (5) is provided with the locking portion. Is configured to be movable between two positions, a lock position that locks the blade body so that it cannot tilt in the width direction and a non-lock position where the engagement relationship is released, and the lock member is The gist of the present invention is to provide lock holding means that engages with the positioning means at the lock position.

[Action]

Therefore, when the lock member is in the unlocked position, the blade body can be tilted in the width direction and used. On the other hand, when the lock member is moved to the lock position, the blade body cannot be tilted in the width direction. Then, since the lock holding means of the lock member engages with the positioning means, the locked state is stably held.

[First Embodiment] The first to thirteenth embodiments of the present invention will be described below.
It will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a head portion 1a extending in the left-right direction is formed at the upper end of the handle 1, and a female screw portion 2 is provided at the center portion in the left-right direction. A pair of accommodating holes 3a are provided on both left and right sides of the female screw portion 2, and a mounting groove 4 is formed so as to connect both accommodating holes 3a on the belly side of the female screw portion 2. A mounting recess 6 for the lock member 5 is formed on the back side of the head portion 1a, and a pair of left and right slide holes 7 extending in the vertical direction are formed in the mounting recess 6. Further, one engaging projection 8 as a positioning means is provided below the mounting recess 6.

On the lower surface of the main body 10 of the blade mounting member 9 provided on the head portion 1a, the female screw portion 2 is provided at the center portion in the left-right direction.
A shaft hole 11 corresponding to is transparently provided. A slide recess 12 for the lock member 5 is formed on the back side (upper side in FIG. 2) of the blade mounting member 9.

As shown in FIG. 9, the female screw portion 2 on the head portion 1a
The lower half of the screw 13, which is a support shaft, is inserted therein and fixed by screwing. The upper half of the screw 13 is inserted into the shaft hole 11 of the blade mounting member 9 so as to be capable of relative tilting, and the head 13a prevents the blade mounting member 9 from coming off from the screw 13 upward. , Permitting the blade mounting member 9 to tilt with respect to the screw 13. A pair of lock holes 3b are provided on the lower surface of the main body 10 so as to correspond to the pair of accommodation holes 3a on the head portion 1a.
Thus, a locking portion that engages with the lock member 5 that has been moved to the lock position is configured. Main body 10 and head portion 1a
A leaf spring 14 is interposed between the blade spring 14 and the leaf spring 14. The leaf spring 14 acts as a restoring means for returning the blade mounting member 9 to its original position when the blade mounting member 9 tilts.

The leaf spring 14 extends in the left-right direction, and has a fixing portion 15 located at the center in the left-right direction as shown in FIGS.
A pair of elastic portions 16 formed so as to extend a little from the left and right ends to the back side (lower side in FIG. 3) and then project obliquely upward, and the tips of both elastic portions 16 are bent backward. It is composed of a pair of engaged parts 17. or,
Each of the elastic portions 16 has its tip end portion 16a bent upward, so that the engaging portion 17 is located above the fixing portion 15. The fixing portion 15 is inserted and fixed in the mounting groove 4 of the handle 1, and both elastic portions 16 have their base end portions elastically moved into both the receiving holes 3a of the handle 1 as shown in FIGS. It can be accommodated.
