Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disposable razor, and more particularly to a disposable razor having a movable, permanently attached blade cover that can be moved to expose or trim the blade as required. Throw away the razor.

The present invention is disclosed in a US patent application filed on December 31, 1979.

This invention is an improvement on the razor disclosed in U.S. Patent Application Ser.

U.S. Patent Application No. 108,747 discloses a device that is permanently but slidingly connected to the blade retainer 18 and suitable for wet shaving the edge of the blade from a closed position that protects the edge of the blade. The movable cover 14 is shown in an exposed open position.

JP-A No. 58-1491 discloses a cover 14 which is in contact with IJ on the razor body, that is, on the blade holding part.
It is shown. The 'L'f'Ck and the wrong place are
It is a lever device pivoted on the razor blade, and the cover is connected to the cover so that it can be moved from the closed position to the open position by operating the lever with one hand. It is.

Japanese Patent Publication No. 58-1214184+ shows an improved operating device in the form of a single-action button 21 mounted on a track 17 on the handle of a razor. This slider is flexibly connected to the cover and allows the slider to be moved along its trajectory.
When you move C, the cover moves along its trajectory.

In this specification, the terms ``blade-1, ``blade package,'' ``blade edge,'' or ``blade glue edge'' each refer to a single blade edge <v ; t1'L number or a plurality of blades.

This invention! A feature is a permanently extended sliding blade cover device with a cover operating lever integrally molded with the cover so as to form a single part with the cover.

Further, a feature of the present invention is that in the razor device described above, the lever includes a handle molded together with a rocker arm that serves as a moving pivot that is operated so as to move by resting on the handle of the razor, with the lever as a fulcrum. That's true.

Further features of the invention are essential for commercial success in the disposable razor market: a disposable razor with a sliding cover of simple design and suitable for high-speed mass production; It is a device.

An example of a razor embodying the features of the invention includes a razor body including a handle, a blade package held by the body;
It comprises a cover permanently attached to the razor body and slidable along it, and a lever or operator integrally formed with the cover, which handle can be operated with one hand by moving the lever about the aforementioned fulcrum. It serves as a fulcrum for the lever used to operate the cover.

The present invention will be described in detail below with reference to the drawings.

Now, in the attached drawings, 1'1) in Figure C5 is a low-cost user that has a handle 11, a blade support part, that is, a razor body [2, a sliding blade cover, that is, a gear lug 13, and a cover operator]4. i3. '(Shows razor.

The external side view of the razor in FIG. 2 shows the cover 13 with the integrally mounted actuator r-14 forming a sliding rocker arm or pivot 17 in contact with the handle 11 at levers 16 and 18.

FIG. 2 shows the cover 13 in its closed position (blade protection position), with the handle 11 serving as the fulcrum of the lever.

Figure 3 shows that the cover is in the open position.
indicates exposed areas suitable for wet shaving.

Lever 16 is restrained, I L 7. Note that the arm or pivot 17 is separated from the handle 11 in the C position. (See also Figure 6).

Figures 4 to 6 show the closed and open positions of the integral parts;
and the unrestrained state in more detail.

In FIG. 4, the cover l:S is closed and the edges 19 and 21 of the blade are protected.

The arm 17 is in contact with the handle 11 when the operating tab of the lever 16 is pressed (turned) with a finger in the direction indicated by the arrow i).

FIG. 5 shows in solid lines the positions of the parts of the razor where the razor is opened and the blade is exposed for wet shaving immediately after the tab 22 is finger pressed or turned.

The arm 17 is placed in the closed position (dotted line) with its fulcrum on the handle ll.
Note that it moves down on the handle between the fulcrum of and the fulcrum of the open position (solid line).

FIG. 6 shows the razor in the open position, the cover operator unrestrained, and the lever 16 and arm 17 separated from the handle 11 by the elastic memory of the material forming the cover and operator together. .

Next, the operation will be explained. It is assumed that the cover 13 is in the closed position shown in FIG. When the tab 22 is pressed, the arm 17 pivots about a point on the handle 11, so that the lever 16 moves the cover 13 in the direction of the arrow, as shown in FIG.
and 21 to expose it suitable for wet shaving.

When operating the tab 22 so that it rotates around the base of the handle 1110, the fulcrum that is the center of rotation of Arno 17 is the fulcrum of the handle.
There is a tendency for the two to move a small distance generally downward from the position indicated by the dotted line in FIG. 5 to the position indicated by the solid line in the same figure.

When tab 22 is loosened, lever IG assumes an unrestrained position as shown in FIG.

When you want to put the razor in the closed position, press the cover 13 in the closed position 111 by pressing it with a suitable finger at the same point indicated by the reference numeral 23 in FIG.
Name 1. Arno, just move it until the 1'/ touches the handle 11.

It should be noted that the operation (opening/closing operation) of the cover 13 can be performed with one hand according to the present invention.
