Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a sheath for covering a blade portion of a knife such as scissors or a knife.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, in this type of blade, the blade may be covered with a sheath for safety. In this case, various retaining means have been devised so that the blade portion is not easily separated from the sheath when the blade portion is inserted into the sheath.

On the other hand, a simple pencil sharpener is commercially available, but this pencil sharpener is small in size, so it is difficult to hold and inconvenient to use.

Therefore, the present invention is to make a pencil sharpener easy to use by using a sheath and a pencil sharpener in combination, and to use the pencil sharpener as a blade retaining means.

[Means for Solving the Problem] In order to solve the above problems, the first invention of the present application is, in a sheath covering a blade portion of a blade, a detachable connecting portion provided on the sheath body and a pencil sharpener, When the pencil sharpener is attached to the insertion opening of the sheath body and the blade portion of the blade is inserted into the sheath body, a retaining means for holding the blade and the sheath body in the inserted state is provided between the blade and the pencil sharpener. The point is that it is provided between them.

The gist of the second invention is that the retaining means is a pressure contact portion that presses the blade.

[Operation] According to the first invention, the blade portion of the blade is inserted into the sheath body through the insertion port of the sheath body. At that time, the blade is securely held by the sheath body by the retaining means.

Further, according to this invention, the pencil sharpener can be used while holding the sheath body. Also, in some cases,
By releasing the engagement state of the connecting portion, only the pencil sharpener can be detached from the sheath body and used. Therefore, it is possible to select the most convenient one for the user, and as a result, the pencil sharpener becomes very easy to use.

According to the second invention, since it is sufficient to provide the pressure contact portion only on one of the blade side and the pencil sharpener side, the configuration becomes extremely simple.

[Embodiment] An embodiment in which the present invention is embodied in a scissor sheath will be described below with reference to the drawings.

As shown in FIGS. 1, 2, and 5, the sheath body 1 is integrally formed of plastic, and the front, rear, left and right walls 1a, 1b, 1c,
It consists of 1d. A storage portion 2 is formed inside the sheath body 1, and an insertion opening 2a is formed in the storage portion 2 at one end of the sheath body 1. Inside this sheath body 1,
The rear wall 1b has a groove 3 extending from the insertion opening 2a to the back of the storage portion 2.
Are formed.

The pencil sharpener 4 is composed of a head 5 and a neck 6 having a U-shaped cross-section protruding from the lower end thereof.
A convex portion 7 as a connecting portion is formed on the inner surface of the. Further, on the outer surfaces of the left and right walls 1c, 1d of the sheath body 1, a recess 8 as a connecting portion is formed near the insertion opening 2a. The neck portion 6 of the pencil sharpener 4 is fitted to the outer surface of the sheath body 1 from the front wall 1a side in the vicinity of the insertion opening 2a of the sheath body 1, and the convex portions 7 of the left and right side plates 6a of the neck portion 6 are attached to the sheath body 1. The pencil sharpener 4 can be detachably connected to the sheath body 1 by being engaged with the recesses 8 of the left and right walls 1c and 1d.
In this state, the head 5 of the pencil sharpener 4 projects forward from the front wall 1a above the insertion opening 2a of the sheath body 1,
The rear surface 9 of the front wall 1a is flush with the inner surface of the front wall 1a and extends upward. On the back surface 9 of the head portion 5, a pressure contact portion 10 is provided as a protrusion preventing means.

The head 5 of the pencil sharpener 4 is composed of a main body 11 and a face portion 12. As shown in FIG. 8, a pair of left and right engaging claws 13 formed inside the face portion 12 are inside the main body 11. The face portion 12 is detachably attached to the main body 11 by being engaged with a pair of left and right engaging holes 14 formed in the main body 11. Body 11
A pencil insertion hole 15 opened upward is formed in the inside of the body 1, and the main body 1 facing the inside of the face portion 12 is formed.
A blade body 16 exposed to the pencil insertion hole 15 is attached to the inner central portion of 1, and a storage recess 17 is formed inside the face portion 12 so as to face the blade body 16.

The scissors 18 as a blade housed in the sheath configured as described above is a pair of scissors pieces 19 supported in an X shape by the opening / closing center shaft 20, and the scissors pieces 19 are both gripping portions 21.
And a blade portion 22.

Now, the blade portion 22 of the scissors 18 is inserted into the housing portion 2 through the insertion opening 2a of the sheath body 1 with the blade portion 22 of the sheath body 1 being in contact with the back surface 9 of the sheath body 1 to open and close the shears 18. Central axis 20
Is guided by the groove 3 in the sheath body 1 and covered by the sheath body 1. At this time, the grasping portion 21 of the scissors 18 is the pencil sharpener 4
It projects above the head 5 while facing the back surface 9 of the head 5.

In this way, in the state in which the blade portion 22 of the scissors 18 is housed in the sheath body 1, the pressure contact portion 10 on the back surface 9 of the head 5 is the scissors 18.
The blade portion 22 of the scissors 18 is pressed against the inner surface of the housing portion 2 of the sheath body 1 and is held by the sheath body 1 since the blade portion 22 of the sheath scissors 18 is pressed.

Particularly, in this embodiment, since the pencil sharpener 4 is attached near the insertion opening 2a of the sheath body 1, it is possible to grasp the sheath body 1 and sharpen a pencil with the pencil sharpener 4, which is very easy to use. . Moreover, since the grip portion 21 of the shears 18 can be pressed by the press-contacting portion 10 provided on the back surface 9 of the pencil sharpener 4, the blade portion 22 of the shears 18 can be securely held with respect to the sheath body 1. It is safe and secure. Therefore, even when performing the pencil sharpening operation by gripping the sheath body 1, carelessly
There is no such thing as coming off.

Furthermore, since the pencil sharpener 4 is attachable to and detachable from the sheath body 1, the pencil sharpener 4 can be detached from the sheath body 1 and used as necessary. Therefore, it is possible to select a convenient usage method for the user, and as a result, the pencil sharpener 4 becomes very easy to use.

On the other hand, in the pencil sharpener 4, since the face portion 12 is detachable, by removing the face portion 12, the chips collected in the storage recess 17 can be discarded. Further, according to the configuration of this embodiment, since the pressure contact portion 10 only needs to be provided on the pencil sharpener 4 side, the configuration is extremely simple. Therefore, it is not necessary to provide a retaining means having a complicated shape such as a locking portion on both the blade 1 side and the pencil sharpener 4 side. In addition, a structure for locking the tip of the blade 22 is not necessary.

In the embodiment described above, the pressure contact portion 10 is provided so as to project from the pencil sharpener 4, but the pressure contact portion 10 may be provided at the grip portion 21 of the scissors 18. Further, the face portion 12 of the head 5 of the pencil sharpener 4 may be changed to faces of various animals other than the above-mentioned embodiment. Furthermore, it can be applied to sheaths other than scissors.

[Effect of the Invention] As described in detail above, in the present invention, since the sheath body can be gripped when the pencil sharpener is used, it is not only very easy to use, but also the pencil sharpener is used. It is safe because the blade can be held in the sheath body.
When the pencil sharpener is detachable from the sheath body, the pencil sharpener can be detached from the sheath body for use.
