Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a safety razor, the purpose of which is to cover the razor with a top plate when the blade base is in a non-use position;
To provide a safety razor which can be exposed from a top plate only when in the use position, has excellent safety, and can be made compact and can be stored in a travel bag etc. without being heavy. There is a particular thing.

Hereinafter, one embodiment of a safety razor embodying the present invention will be described based on the drawings.

Reference numeral 1 denotes a holder having a distal end neck portion 2 bent diagonally forward and upward, and the neck portion 2 is formed into an opening-like cross section to form a fitting recess 3 and a pair of support pieces 4.

Reference numeral 5 denotes oval-shaped support holes bored in the longitudinal direction of the neck portion 2 on the outer surfaces of the pair of support pieces 4, and in the upper half thereof, a connecting pin for rotatably supporting a blade stand 8, which will be described later. A through hole 7 through which the numeral 6 passes is provided.

8, the connecting portion 9 provided at the center position of the rear side edge connects to the neck portion 2.
The blade base is fitted into the fitting recess 3 and rotatably connected to the holder 1 by the connecting pin 6, and has a pair of mounting protrusions 10 protrudingly formed on both sides of its upper surface. A certain degree of rotational resistance is provided by the frictional force generated between the fitting recess 3 and the fitting recess 3 .

Reference numeral 11 denotes a support frame formed on both left and right edges of the blade base 8, each of which has a concave outer surface and a step-like notch in cross section. is formed.

Reference numeral 15 denotes a guard supported and fixed between the tip portions of the pair of left and right support frames 11.

Reference numeral 16 indicates that a pair of left and right through holes 17 are connected to the mounting protrusions 10 of the blade base 8.
As shown in FIG. 3, the upper end of the attachment protrusion 10 is flattened and fixed to the blade stand 8.

Reference numeral 18 denotes a top plate that covers the blade stand 8 from above the razor 16 so as to be relatively movable, and a guide piece is formed in the center of both left and right edges to extend downward and has a locking pawl 19a at its tip. 1
9 is an engagement sliding portion 12 formed on the support frame 11 of the blade stand 8;
The second
As shown in the figure, the attachment protrusion 10 with the razor 16 fixed thereto is loosely fitted into a pair of left and right oval-shaped guide holes 20 bored on both sides of the lower surface, as shown in FIGS. 3 and 4.

Reference numeral 21 denotes a support pin provided at the lower part of the rear end of the pair of left and right connecting pieces 22 provided at the center position of the rear edge of the top plate 18, and is rotatable and slightly attached to the lower part of the support hole 5 of the neck part 2 of the holder 1. It is fitted so that it can be driven.

Therefore, the top plate 18 can be rotated about the support pin 21 with respect to the holder 1.

In this case, the guide piece 19 of the top plate 18 is slidably engaged with the engagement sliding portion 12 of the blade stand 8 (which rotates around the connecting pin 6) having a different rotation center position. , the top plate 18 rotates together with the blade stand 8 and performs relative reciprocating motion in the front and back direction with respect to the blade stand 8. When the blade stand 8 is in the position shown in FIGS. 3 and 5, the top plate 18 The plate 18 is located at the rear of the blade stand 8 to expose the razor 16, and when the blade stand 8 is rotated downward to the position shown in FIGS. 4 and 6, the top plate 18 is adapted to move relative to the front position with respect to the blade stand 8 to cover the razor 16.

Note that when the top plate 18 is located at the position shown in FIG. Even if a force to rotate the beard upward is applied when shaving, the beard does not rotate upward any further.

In addition, in this state, when the razor 16 is pressed against the skin surface at the beginning of shaving, even if a force is applied to rotate the blade base 8 downward, the connecting portion 9 and the fitting recess will not connect as described above. 3, the blade base 8 is held in the position shown in FIG. 5 by the rotational resistance generated in the blade base 8.

On the other hand, when the top plate 18 is similarly located at the position shown in FIG.
, the blade stand 8 and the top plate 18 do not rotate downward any further.

Next, the operation of the safety razor constructed as described above will be explained.

First, from the bent state of the blade stand 8 as shown in FIG. 6 to the state of the blade stand 8 shown in FIG. When the top plate 18 is rotated (until they come into contact with each other), the top plate 18 rotates together with the blade holder 8, and continues to move backward relative to the blade holder 8, removing the razor hidden under the top plate 18. 16 is exposed and becomes usable.

After use, if the blade stand 8 is rotated as shown in FIGS. 5 and 6, the top plate 18 will move to its original forward position, so the razor 16 will be covered and hidden by the top plate 18. It will be done.

Therefore, the razor 16 is always covered by the top plate 18 when not in use, making it extremely safe.
Since the top plate 18 is also foldable, it becomes compact and can be safely stored in a travel bag or the like without being bulky.

Next, a second embodiment of the present invention will be described based on FIGS. 7 to 14.

In this embodiment, support holes 3 are formed on the outer surface of the pair of support pieces 4 of the neck portion 2 of the holder 1, contrary to the embodiment described above.
1, and a through hole 32 is transparently provided in the lower front half of the support hole 32, and the blade stand 8 is rotatably connected with the connecting pin 6. On the other hand, a top plate 18 is provided in the upper rear half of the support hole 31. The support pin 21 is rotatably fitted, and the rotation center position of the top plate 18 of the above embodiment, that is, the support pin 21 is placed diagonally behind the connecting pin 6 as shown in FIGS. 3 and 4. In contrast to the lower part, in this embodiment, the support pin 21 is fitted diagonally backward and upward to the connecting pin 6, as shown in FIGS. 11 and 12.

Therefore, by rotating the blade stand 8 upward from the operating position where the razor 16 is exposed from the top plate 18 as shown in FIG. The razor 16 can be covered and hidden by the relative movement, and the same effect as in the embodiment described above can be achieved.

Further, as mentioned above, the upward or downward rotation of the blade base 8 and the top plate 18 that occurs when shaving can be prevented by rotational resistance due to the fitting between the connecting portion 9 and the fitting recess 3, or by the guide piece 19, respectively. This is prevented by the contact between the stopper surface 14 and the stopper surface 14.

Note that the present invention is not limited to the above-mentioned embodiments, but can also be implemented in the following embodiments.

B The rotation of the blade rest 8 and the top plate 18 is controlled by the mounting protrusion 1 of the blade rest 8.
0 and the guide piece 19 of the top plate 18.

Open: Drill the support hole 5 along an appropriate direction and attach the connecting pin 6.
The fitting position of the support pin 21 of the top plate 18 should be changed as appropriate.

... The support hole 5 and the through hole I are formed in the support piece 4 of the holder 1.
Instead, a hole for passing through the connecting pin 6 and a long hole for fitting the support pin 21 of the top plate 18 are separately provided.

As described in detail above, the present invention has a blade holder on which a razor is attached to the tip of the holder, and a top plate that is slidably engaged with the blade holder in the front and rear directions above the blade holder. , are rotatably attached so that the center positions of rotation are different from each other, and by rotating the blade base, the top plate is rotated and moved relative to the blade base in the front and back direction, and the above-mentioned By making the razor attached to the blade stand appear and disappear, the razor is covered by the top plate when the blade stand is not in use, and the razor is only exposed from the top plate when it is in the use position, making it safe. This is an industrially excellent invention as a safety razor, as it is highly durable and can be made compact so that it can be stored in a travel bag without being too heavy.
