Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter knife with improved safety.

[0002]

2. Description of the Related Art Like a conventional cutter knife, a knife that slides a blade body in and out has a structure in which a sharp tip always comes out of a storage case and a blade body follows. There was a particular danger in work that did not use.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a cutter knife capable of performing a safe operation by exposing the blade body without exposing the tip so as to eliminate the above danger.

[0004]

In order to achieve the above-mentioned object, one of the safety cutter knives of the present invention comprises a blade body formed by sliding a storage case (2) divided from a storage case body (1). Without exposing the tip of (3)
It is characterized in that other portions of the blade body (3) can be exposed.

[0005] Another one of the safety cutter knives of the present invention is to cut off a part of the storage case body (7) and to remove a part of the blade body (8) without exposing the tip of the blade body (8). A storage case (6) that is exposed and divided is provided.

[0006]

The safety cutter knife of the present invention is provided with an exposed portion of the blade in addition to the conventional entrance and exit of the blade, and by working at this portion, compared with the case where the tip is exposed. Work can proceed safely.

Further, in this case, even if the safety cutter knife is dropped, the blade body and the object at the drop destination are rarely damaged.

[0008]

1 and 2 are perspective views of an embodiment showing a main part of the safety cutter knife according to the first embodiment. FIG. 3 is a rear view of FIG. 1, and FIG. 4 is a rear view of FIG. FIG. 1 shows a state in which the divided storage case (2) is slid and the tip of the blade body (3) is not exposed.

FIG. 2 shows a state where the divided storage case (2) is accommodated in the storage case main body (1) and the tip of the blade body (3) is exposed.

FIG. 3 shows a state where the divided storage case (2) is fixed to the storage case body (1) by the fixing device (4), and the fixing device (4) is divided into the storage case (2). The groove (5) of the storage case body (1) can be moved in conjunction with and can be fixed at an arbitrary position. FIG. 4 shows the position of the fixing device (4) when the storage case (2) is stored in the storage case body (1).

FIGS. 5 and 6 are perspective views of an embodiment showing a main part of the safety cutter knife according to the second aspect.
Shows a state in which the tip of the blade (8) is exposed. In FIG. 6, the tip of the blade (8) is covered with a divided storage case (6), and the other part of the blade (8) is exposed. It is.

FIGS. 7 and 8 are perspective views of another embodiment showing the main part of the safety cutter knife according to claim 1.
The basic structure is the same as that shown in FIG. 1 and FIG. 2, but the divided storage case (2) is interlocked with the fixing device (9),
The fixing device (9) is arranged on the same side as the fixing device (10) for fixing the blade body (3), and when the fixing device (9) is moved in the blade tip direction, the blade body (3) moves by the same amount and the fixing device (9) is moved. ) Is in contact with the fixing device (10) so that the tip of the blade body (3) is not exposed.

[0013]

According to the present invention, the danger of the tip portion, especially when the blade body is extended, is removed, and the exposed blade body has a portion covered by the storage case, so that the blade body is bent in a direction outside the work. This also eliminates the tendency of the blade body to break due to being cut, thus enabling safe cutting work.
