Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip device attached to, for example, a handle of a kitchen knife, a kitchen knife provided with the anti-slip device, and a handle of the kitchen knife.

[0002]

2. Description of the Related Art In general, a kitchen knife has a cutting edge formed of steel, stainless steel, or the like, and a wooden or synthetic resin handle is attached thereto. Such knives are classified into blade knives, thin knife knives, and willow knife knives according to the shape of the cutting edge. Among these, for example, the blade of the blade is thick,
Utilizing the fact that the whole is heavy, it has also been used to swing the fish down from above and cut the fish together with the bones.

[0003]

By the way, the handle of a kitchen knife becomes slippery, for example, when water adheres to it during use, so that it is necessary to squeeze the handle firmly. Usability gradually decreases. In particular, when the knife is used by swinging it down from above as described above, for example, it is necessary to sufficiently wipe off the moisture attached to the handle, and it is necessary to firmly grasp the handle so that the handle does not come out of the hand. Therefore, its usability is hard to obtain.

[0004] Further, when the handle is made of wood, if the moisture remains attached, it rots or germs are formed and cannot be used. Therefore, it is necessary to sufficiently wipe off the moisture after use. This also causes a problem that the usability is reduced or sufficient durability cannot be obtained.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to provide a non-slip anti-slip device which can be mounted on a handle of a kitchen knife or the like so that the anti-slip can be suitably obtained and the usability can be improved. A knife and a handle of a kitchen knife provided with a tool and a non-slip device.

[0006]

Accordingly, a non-slip device according to a first aspect of the present invention is a non-slip device made of synthetic resin which is mounted so as to surround an outer periphery of a grip portion to be gripped by hand. A heat-shrinkable tube-shaped surrounding portion is provided, and a plurality of holes penetrating in the thickness direction are formed in the surrounding portion.

[0007] The anti-slip device having such a structure is inserted into a handle of a kitchen knife, for example, and heated and thermally contracted.
It is attached to the outer periphery of this handle. In this mounting state, the step surface on the peripheral edge of the hole is caught by the palm holding the hole, and an anti-slip effect is obtained. In particular, according to the structure in which the above-described hole is formed and the periphery thereof is stepped, the more appropriately the thickness of the anti-slip device is, the more the corner of the step is deformed in the direction of hand slip. Therefore, even if the thickness is small, the anti-slip effect is suitably exhibited.
As a result, an excessive gripping force is not required, and since it can be formed thinner, a decrease in the original gripping feeling when gripping the handle can be suppressed as much as possible, and the delicate movement of the hand can be transmitted. , The usability is improved.

According to a second aspect of the present invention, there is provided the anti-slip device according to the first aspect, wherein the anti-slip device is formed by adding an antibacterial agent to a synthetic resin material.

In this case, an antibacterial function is further added,
Since the propagation of various bacteria is suppressed, a more hygienic use state can be maintained.

According to a third aspect of the present invention, there is provided a kitchen knife having a non-slip device, wherein the anti-slip device according to the first or second aspect is mounted on an outer periphery of a handle.

As described above, in the kitchen knife in which the above-mentioned slip stopper is attached to the handle, the above-mentioned anti-slip effect is suitably obtained, so that an excessive gripping force is not required, and moreover, when the handle is gripped, The reduction of the grip feeling can be suppressed as much as possible, and the delicate movement of the hand can be transmitted to perform cooking as intended, thereby improving the usability.

According to a fourth aspect of the present invention, the handle of the kitchen knife is characterized in that a coating layer comprising a coating film containing an antibacterial agent is formed on the surface of the wooden handle body.

In addition to the improved antibacterial agent, a hygienic use state is maintained, thereby improving the usability.

According to a fifth aspect of the present invention, there is provided the handle of the kitchen knife according to the fourth aspect, wherein the anti-slip device according to the first or second aspect is mounted on the outer periphery of the handle body on which the coating layer is formed. And

According to this configuration, the above-described anti-slip effect can be obtained by the anti-slip device. In this case, for example, even if water remaining near the periphery of the hole after use is not sufficiently wiped off, This does not touch the wooden handle body by the covering layer, and therefore, the durability is improved and the usability is further improved.

[0016]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. 1 (a) and 1 (b) show a manufacturing process of the anti-slip device 1 according to the present embodiment, and FIG.
FIG. 3 is an explanatory view showing a case where the camera is mounted on a vehicle.

As shown in FIG. 1A, the anti-slip device 1 first forms a tubular molded body (surrounding portion) 1a having a circular cross section by a resin extruder (not shown). As shown in FIG. 1B, the shaped body 1a is folded flat and a plurality of circular holes 2 are formed in the shaped body 1a by punching and then cut into an appropriate length. It is formed.

The anti-slip device 1 is made of, for example, a heat-shrinkable ethylene-propylene copolymer, and contains a predetermined amount of an inorganic metal-based antibacterial agent and is extruded by the above-mentioned molding machine. For example, the thickness is 0.5
mm, a width of about 45 mm when folded flat (about 30 mm in diameter when circular) and a diameter of each circular hole 2 of 8 to 10 mm as shown in FIG. The distance between the center points is set to 10 to 15 mm, and the circular holes 2 are formed in a shape arranged in a lattice.

When the anti-slip device 1 as described above is mounted on a handle of a kitchen knife, for example, the anti-slip device 1 is cut in accordance with the length of the handle 4 of the kitchen knife 3, as shown in FIG. Then, this is expanded into a substantially circular shape, and the handle 4 of the kitchen knife 3 is inserted therein.
The knife 3 shown in the figure is a blade knife with a ridge portion of the blade 5 formed thickly to about 6 mm, and the cross section of the handle 4 has a longitudinal major axis at the rear end side. Size is about 3
It is formed in an oval shape with a short axis dimension of about 25 mm in a horizontal direction of 0 mm.

When the handle 4 is inserted into the non-slip device 1 as described above, for example, hot water is applied to the non-slip device 1 to contract. And this anti-slip device 1 is shown in FIG.
As shown in the figure, the knife 4 is mounted on the handle 4 so as to cover the outer periphery of the handle 4. In this mounting state, the elastic contraction force of the anti-slip device 1 acts toward the center of the handle 4, whereby the anti-slip device 1 is firmly tightened on the outer periphery of the handle 4.

When the size of the anti-slip device 1 before the heat shrinkage is, for example, about 30 mm in diameter as described above,
For the handle 4 having a diameter of about 15 to 25 mm, the above tightened state can be obtained by heat shrinkage. In addition, when heat shrinkage is caused in the anti-slip device 1, it is possible to heat it by directly heating with a fire, for example, in addition to applying hot water as described above.

In the kitchen knife 3 on which the anti-slip device 1 is mounted as described above, the anti-slip device 1 is as thin as about 0.5 mm when holding the handle 4 and cooking. It is possible to obtain a neat gripping feeling without damaging the outer peripheral shape of the handle 4 as in the related art. Moreover, even with such a thin shape, the peripheral edge of the circular hole 2 becomes a step surface that stands substantially perpendicularly from the surface of the handle 4, and the corners on the surface side of the step surface are caught by the palm, so that, for example, A more reliable non-slip effect can be obtained as compared to a non-slip device or the like having a projection.

In other words, in a structure in which a projection is provided on the surface to obtain a non-slip effect, the projection is easily elastically deformed locally by being pushed by the palm when pushing and pulling the kitchen knife. Are deformed to an obtuse angle, and the catch of the palm is easily damaged. For this reason, it is difficult to obtain a sufficient anti-slip effect.

On the other hand, by forming the circular hole 2 with a reduced thickness as in the present embodiment, the entire surrounding portion 1a other than the circular hole 2 is tightened to the surface of the handle 4, so that the circular shape is formed. The periphery of the hole 2 is also in a tightened state where almost no elastic deformation can occur. Thereby, the right-angled shape of the peripheral edge of the circular hole 2 is maintained even if the circular hole 2 is pushed by the palm. As a result, a more reliable anti-slip effect can be obtained without impairing the catch on the palm.

As described above, the anti-slip device 1 of the present embodiment has a small thickness, which makes it possible to maintain the grip of the original handle 4 as much as possible and to obtain a more effective anti-slip effect. For example, when it is attached to the handle 4 of the blade knife 3, it does not require excessive gripping force even when the fish is used to sever the bone, and the blade edge can be delicately moved as intended. Becomes easier, and the usability is improved.

Further, since the above-mentioned anti-slip device 1 is formed by containing an antibacterial agent, propagation of various bacteria is suppressed,
A more hygienic use state can be maintained, which also improves usability.

Since the anti-slip device 1 is made of a heat-shrinkable synthetic resin material, the anti-slip device 1 can be freely mounted on any of the existing knife knives in addition to the above-mentioned knife blade, and each can be easily used. Can be improved.

Next, another embodiment of the present invention will be described with reference to FIG.
