Description

[Detailed description of the invention] This invention relates to a knife with a sheath.The purpose of the invention is to have a simple structure that allows the sheath to be securely fixed with light force so that the body does not touch the inner surface of the sheath. This prevents the blade from spilling on the edge of the blade, scratching the side of the blade, and damaging the sheath due to contact with the blade, and also prevents the periphery of the insertion opening from cracking. The purpose of the present invention is to provide a knife with a sheath that does not have a sheath.

An embodiment embodying the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a pair of flat side plates constituting the left and right sides of the sheath, which are spaced apart at a predetermined interval to accommodate the body 7 of the paring knife 5. They extend parallel to each other. Reference numeral 2 denotes an elongated insertion opening opened between the base ends of both side plates 1. 3 inserts the proximal end of the sheath into the insertion port 2
It is a slit formed by cutting out an oblique shape downward from the lower part of the body toward the front, and its upper end communicates with the insertion port 2. The slit 3 opens the lower part of the insertion port 2 to the lower outside of the sheath. The slits 3 also allow the side plates 1 of the sheath to expand in the left-right direction at the insertion opening 2 portion against their own elasticity.

Reference numeral 4 denotes a plurality of drainage holes transparently provided at the tips of both side plates 1 of the sheath, through which water and air can pass when cleaning the inside of the sheath.

6 is the handle of the paring knife 5. Reference numeral 8 denotes a fitting portion protruding from the front end of the handle 6, and is formed in a flat shape so as to be press-fitted into the insertion opening 2 of the sheath when the sheath is fitted onto the body 7.

Now, when the body 7 of the paring knife 5 is completely housed in the sheath, the fitting part 8 at the front end of the handle 6 is press-fitted into the insertion opening 2 of the sheath. Therefore, the side plates 1 of the sheath are easily expanded to the left and right sides at the insertion opening 2 portion against their own elasticity, and this expansion operation is permitted by the slits 3 below the insertion opening 2.

Therefore, the fitting part 8 is lightly and smoothly press-fitted into the sheath, and the sheath does not easily come off from the handle 6 after being press-fitted. Moreover, since the fitting part 8 is inserted smoothly in this manner, there is no fear that the peripheral edge of the insertion opening 2 of the sheath will crack during insertion, and therefore there is no need to provide any special means to prevent this cracking.

Furthermore, since the fitting part 8 at the front end of the handle 6 is press-fitted into the insertion opening 2 of the sheath, the blade edge and side surface of the body 7 are held so as not to touch the sheath. Therefore, it is possible to prevent the blade edge from being damaged due to contact between the blade and the sheath, damage to the side surface of the blade, and damage to the sheath.

The above-mentioned sheath has a drainage hole 4 formed in its side plate 1, so if the inside of the sheath becomes dirty and needs to be washed, water or air should be poured into the inside from the insertion opening 2 of the sheath as shown in Fig. 3. If it is strongly blown, the flow of water and air can remove the dirt inside the sheath and easily discharge it to the outside through the discharge hole 4.

As detailed above, the present invention has a simple structure,
The scabbard can be securely fixed with light force so that the shell does not touch the inner surface of the sheath, and contact between the shell and the scabbard will prevent spills on the edge of the knife and scratches on the sides of the shell. This is a practically preferable idea for a knife with a sheath, since it can prevent the sheath from sticking or being damaged, and also eliminates the risk of the peripheral edge of the insertion opening breaking.

Claims (1)

[Claims for Utility Model Registration] 1. A knife 5 having a handle 6 and a body 7, and a pair of flat side plates 1 and both side plates 1 that face each other and extend substantially parallel at a predetermined interval capable of accommodating the body 7.
The front end of the handle 6 is press-fitted into the insertion opening 2 when the body 7 is stored, and the body 7 is inserted into the side plate 1.
A fitting part 8 is formed in a flat shape to hold the fitting part 8 so as not to touch the inner surface thereof, and at the lower end of the insertion opening 2, each side plate 1 moves laterally against its own elasticity when the fitting part 8 is press-fitted. A knife with a sheath, characterized in that a slit 3 for allowing the sheath to be expanded is formed so as to communicate with the insertion opening 2 and to extend diagonally forward and downward while being open to the lower outside of the sheath. 2. The sheathed knife according to claim 1, wherein the side plate 1 is provided with a discharge hole 4 at its tip.
