Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety knife having a sheath for covering the blade of the knife when not in use.

[0002]

2. Description of the Related Art Conventionally, there has been provided with a sheath for covering a blade of a cutting knife or the like which is not used. However, it is extremely dangerous if the pods fall out carelessly. For example, if a child puts it in a bag or the like and carries it out, if the child tries to use it and scratches the inside of the bag, there is a high risk of being injured by touching the bare blade.

In order to prevent such a danger, there is a structure in which the sheath cannot be removed unless a certain amount of force is applied by devising the space inside the sheath or incorporating a spring.

[0004]

However, although it may be possible to inadvertently pull out by adopting a structure in which the sheath cannot be pulled out unless a certain amount of force is applied, it is very inconvenient to insert and remove. Occurs,
If you try to pull it out suddenly while applying force, you will have excess power and you may be injured by the blade.

In any case, there is a problem that the manufacturer takes responsibility in the event of an accident unless reliable safety measures are taken. Therefore, effective measures have been demanded.

The present invention has been made for the purpose of providing a very safe and easy-to-use sword which can be easily inserted and removed from a pod and which can be carelessly pulled out when not in use.

[0007]

According to the invention of claim 1, in a safety sword equipped with a detachable sheath for covering the blade of the sword, a rotatable hook is provided on the sheath and the blade is attached. The fixed handle has a side portion provided with a concave portion to which the hook can be hooked to prevent the sheath from accidentally falling off.

According to the invention of claim 2, in the safety sword of claim 1, means for providing a recess in which the hook can be hooked is also provided on the sheath side.

[0009]

With the above measures taken, when the sword is not used, the hooks provided on the sheath are rotated to engage with the recesses provided on the handle, and the sheath is connected to the handle by the hooks. It becomes a state and cannot escape. When using a sword,
The pod can be easily removed by removing the hook from the recess of the handle.

The hook that is removed from the recess of the handle can be stopped by hooking in the recess on the sheath side.

[0011]

The safety knife according to the present invention will be described in detail below with reference to the drawings showing the embodiments thereof.

In FIG. 1, reference numeral 1 denotes a safety knife according to the present invention, which comprises a handle 3 to which a blade 2 is fixed and a detachable sheath 4 for covering the blade 2. The sheath 4 is provided with a metal hook 6 which is rotatable around the mounting hole 5, and the sheath hook is placed at the sheath position where the hook hook 6 abuts when the hook 6 is rotated to the sheath side. The recess 7 is provided.
Further, a groove 9 is provided from the mounting hole 5 toward the handle side.

Further, a handle-side recess 8 is provided at a position of the handle which is brought into contact when the hook 6 is rotated toward the handle with the sheath 4 attached. Therefore, when the sheath 4 is attached and the latch hook 6 is rotated toward the handle side, the root portion of the latch hook 6 fits into the groove 9 and the tip end of the latch hook 6 is the recessed portion 8. Fit in.

The hooking hook 6 is formed by bending an elastic steel wire and inserting it into the mounting hole 5 so as to be freely rotatable. The hooking hook 6 is securely fitted into the recesses 7 and 8. A pipe 61 is attached to the tip of the stop hook 6.

The surface of the handle 3 is covered with rubber so that it is not slippery. However, the concave portion 8 and the end portion 31 may be molded of hard resin. Further, irregularities may be formed on the surface.

The hook 6 need not be a steel wire but may be made of any material that can be connected to the handle. For example, a resin or elastic string may be used. If molded with resin, the protrusion as a knob can be easily molded. Also, the hook 6 has two hooks on the sheath side and the handle side.
It may be biased to stabilize in position.

[0017]

According to the first aspect of the present invention, when not in use, the sheath covered with the blade is connected to the handle by the hook, so that it is possible to prevent accidental disengagement and safety. To be Further, according to the second aspect, since the hook for pulling out the sheath removed from the blade can be stopped by hooking the hook on the recess on the sheath side, the effect that the hook is not an obstacle is obtained.
