Description

[Detailed Description of the Invention] Technical Field This invention relates to a protective cover that covers the blade of scissors for safety when not in use.

Conventional technology Conventionally, this type of protective cover was applied for in 1973.
There is one described in No. 145998. In this protective cover, the base of the upper wall of the plastic sheath is cut out, and an elastic protrusion extending from the upper wall is provided in the cut opening, and a fitting hole is bored in the protrusion, and a scissor blade is provided. When the blade part is inserted into the sheath body through the resection opening, the caulking screw head of the blade part is pushed into the fitting hole of the protrusion and is detachably attached.

However, in order to fit and remove the scissor blade into the sheath, it was necessary to lift the elastic protrusion and insert and remove the caulking screw head into the fitting hole of the elastic protrusion. Therefore, it is troublesome to fit and remove the scissor blade portion into the sheath body.

Purpose The purpose of the present invention is to provide a protective cover for scissors that allows the blade to be easily inserted into and removed from the sheath body.

Structure of the invention In order to achieve this object, the present invention includes cutting out at least one side wall of both side walls of the insertion opening of the sheath body, forming an elastic stopper protrusion on at least one side of the notch, and using the scissors. When the two swords are inserted into this sheath, the head of the spindle that supports the two swords so that they can be opened and closed comes into contact with the side edges of this stopper protrusion, and resists the elasticity of the shaft to open and close the two opposite sides of the notch. The stopper protrusion is configured to return with its elasticity and lock the head of the spindle as the gap is widened.

Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. A bow-shaped stopper protrusion 4 is formed on one side. Both ends 4a of this stopper protrusion 4
is integrally connected to one side of the notch 3, and both ends 4
A flexure space 4 between a and one side of the notch 3
b is formed, and the stopper protrusion 4 itself has elasticity.

The pair of scissors consists of a blade 5 and a handle 6, which are stacked on top of each other and supported by a support shaft 7 (bolt and nut) so as to be openable and closable. And both blades 5
When the two are inserted into the sheath body 1 through the insertion opening 2 in a mutually closed state, the support shaft 7 is inserted as shown in FIG.
The head 7a at one end (in this embodiment, it is a nut, but a bolt head can also be used) first comes into contact with the arcuate side edge 4c of the stopper protrusion 4 and the side edge 3a of the notch 3 facing the stopper protrusion 4. Then, the stopper protrusion 4 is flexed against its elasticity toward the flexure space 4b to spread out the space between the side edges 3a and 4c, and the head 7a of the support shaft 7 is cut out as shown in FIG. When the stopper protrusion 4 moves to the inner side of the portion 3, the stopper protrusion 4 returns due to its elasticity and locks the head 7a of the support shaft 7. Therefore, both blades 5 can be easily fitted into the sheath body 1, and the head 7a of the spindle 7 will not easily slip out of the notch 3, so that the scissor blade 5 can be stably inserted into the sheath body 1. It is well accommodated. In addition, when pulling out both blades 5 from the sheath body 1, the stopper protrusion 4 bends and becomes unlatched from the head 7a of the support shaft 7, as described above.
Both sword blades 5 can be easily separated from the sheath body 1.

In the second embodiment shown in FIGS. 4 and 5, notches 3 are formed on both side walls of the insertion opening 2 of the sheath body 1, and the notches 3 are located at diagonal positions on both sides of each notch 3. A stopper protrusion 4 similar to the first embodiment is formed on one side. Therefore, the first
Unlike the embodiment, the head 7a of the support shaft 7 may be engaged with the stopper protrusion 4 of any one of the notches 3.
It should be noted that if not only a nut but also a bolt head is used as the head 7a of the support shaft 7, these will be locked to both stopper protrusions 4.

In the third embodiment shown in FIG. 6, the stopper protrusion 4 has a cantilever shape in which only one end 4a thereof is integrally connected to one side of the notch 3, and its free end is connected to one side of the notch 3. A bending space 4b is formed between the cutout portion 3 and one side of the notch portion 3, which extends along the side toward the inner side thereof. Its operation is similar to that of the first embodiment.

In the fourth embodiment shown in FIG. 7, the stopper protrusion 4 has a cantilever shape in which only one end 4a thereof is integrally connected to one side of the notch 3, and its free end is connected to the other side of the notch 3. It extends toward the side and is always in an upright state, and has elasticity so that it returns to this upright state when it falls down. When the two blades 5 are fitted into the sheath body 1, the head 7a of the support shaft 7 is aligned with the side edge 4c of the stopper protrusion 4 and the side edge 3a of the notch 3, as shown by the imaginary line in FIG. When the stopper protrusion 4 first comes into contact with the stopper protrusion 4 and then falls down and the head 7a of the support shaft 7 moves to the inner side of the notch 3, the stopper protrusion 4 returns from the collapsed state to the upright state due to its elasticity. 7th
The head 7a of the support shaft 7 is locked as shown by the solid line in the figure. The same applies when removing both blades 5 from the sheath body 1.

In the fifth embodiment shown in FIG. 8, the stopper protrusion 4 is formed to bulge from one side of the notch 3, and both sides 2a of the notch 3 are made elastic. In this case, the stopper protrusion 4 has elasticity due to the both side portions 2a.

In each of the above-mentioned embodiments, it is also possible to form stopper projections 4 on both opposing sides of the notch 3.

Effects According to the present invention detailed above, at least one side wall of both side walls of the insertion opening portion 2 of the sheath body 1 is cut out, and at least one side of the cutout portion 3 is formed with an elastic stopper protrusion 4. Therefore, there is an effect that the blade 5 of the scissors can be easily fitted into and removed from the sheath body 1.
