Description

[Detailed description of the invention] This invention relates to a safety razor, and its purpose is to provide a razor cleaning mechanism with a very simple structure on the blade stand to which the razor is attached, and to make it easy to operate. The purpose of this product is to provide a safety razor that can remove shavings from the razor and allow you to shave comfortably.

Reference numeral 1 denotes a holder molded from a metal plate, and a gripping part 3 is formed at the tip of a handle 2 by bending it into a U-shaped cross section and forming a fitting recess 3a.

Reference numeral 4 designates a rectangular through hole provided in the center of the rear side of the holding portion 3 as shown in FIG.

Reference numeral 5 denotes a blade base having an approximately rectangular shape as a whole that is fitted into the fitting recess 3a of the clamping portion 3, and the frame portions 6 on both sides thereof
A support piece 9 having a mounting protrusion 8 on the upper surface is formed extending inward at the inner side of the center position of both side frame parts 6.

Reference numeral 6a denotes an engagement protrusion protruding from the upper part of the both side frame parts 6, into which the upper side edge of the clamping part 3 of the holder 1 is inserted.

Reference numeral 10 denotes a flexible flexible portion integrally connecting the rear ends of the both side frame portions 6, and an operating piece 1 is provided on the rear side of the center portion.
1 is formed, and a pair of connecting portions 12 extend forward from the front side of the central portion thereof so as to pass between the pair of left and right support pieces 9.

A cleaning piece 13 is integrally formed at the tips of the pair of connecting parts 12 in parallel with the guard 7, and both ends of the cleaning piece 13 are located in front of the support piece 9.

Therefore, when the operation piece 11 is pushed forward, the flexible part 10 is bent forward as shown in FIG. 5, and the cleaning piece 13 is pushed forward via the connecting part 12.

Conversely, when the operating piece 11 is released, the cleaning piece 13 returns to its original position due to the restoring force of the flexible portion 10, as shown in FIG. 5a.

In this embodiment, the width W of the flexible part 10 is reduced by cutting out the rear side surface of the flexible part 10 so that the flexible part 10 can be more easily bent.

In addition, the upper and lower surfaces of the flexible part 10, the connecting part 12, and the operating piece 11 are cut out as shown in FIG. Piece 11
The thickness D3 is made thinner than the thickness of the supporting piece 9 so that the upper and lower surfaces thereof do not come into contact with the lower surface of the razor 14 and the inner surface of the lower part of the holding part 3, respectively, which will be described later.

Reference numeral 14 denotes a razor having a blade on its front edge, and a mounting protrusion 8 protruding from the support piece 9 of the blade stand 5 is inserted into a pair of left and right through holes 15 of the razor.

The upper end of the mounting protrusion 8 is crushed as shown in FIGS. 4a and 4l, and the razor 14 is fixed to the support piece 9 of the blade stand 5.

Then, as shown in FIG. 3, the blade stand 5 with the razor 14 attached is inserted into the fitting recess 3a of the holder 1 and the clamping part 3 so that the operation piece 11 protrudes from the through hole 4 of the clamping part 3. It is inserted and fixed.

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

Now, if shaving scum has adhered to the lower surface of the tip of the razor 14, if you push forward with your finger the operating piece 11 that protrudes from the rear of the clamping part 3, the flexible part 10 will bend forward and the cleaning piece 13 will move as shown in Figure 4. As shown in FIG. 2, since the lower surface of the razor 14 is pushed forward while making sliding contact, the shaving scum attached to the lower surface of the razor 14 is removed forward.

Once the shavings have been removed, when the operation piece 11 is released, the cleaning piece 13 returns to its original position due to the restoring force of the flexible portion 10, as shown in FIG. 4a, and is ready for use.

In this way, the operation for removing shaving dregs can be performed with a single touch, and the shaving dregs can be removed reliably.

In addition, a cleaning piece 13 that moves back and forth directly on the blade stand 5 itself to remove shaving scum attached to the razor 14 is provided, which simplifies the structure and reduces the cost, unlike the conventional cleaning method that only used expensive safety razors. The mechanism can be incorporated into relatively inexpensive disposable safety razors without increasing the price.

Furthermore, the thicknesses DI, D2. Since the cleaning piece D3 is made thinner than the cleaning piece 13, when they move back and forth, the same flexible part, operating piece, and connecting part 10.11.1 are attached to the lower surface of the razor 14 and the inner surface of the lower part of the holding part 3.
Since the upper and lower surfaces of 2 do not come into contact with each other, only a small force is required to press the operating piece 6, allowing smooth operation.

As detailed above, this idea has a razor attached to the top,
A bending part that bends in the front-rear direction is provided for the blade base attached to the clamping part of the holder, and a cleaning piece that is movable back and forth is connected to the bending part in contact with the front lower surface of the razor, and the same An operating piece for moving the cleaning piece back and forth is formed on the rear side of the flexible part, and is protruded from the rear side of the clamping part, so that the razor can be attached to the blade stand itself, which has a very simple structure. This invention has practical origins as a safety razor because it can function as a cleaning mechanism, and also has the effect of reliably removing shaving scum attached to the razor with simple operation.
