Description

The present invention relates to a fruit knife suitable for peeling a spherical fruit or vegetable such as an apple, pear or potato basket.
More particularly, the present invention relates to a fruit knife that has a blade for cutting such peeled fruits or vegetables, and has improved convenience when using the blade and storage safety when not in use.

As for radish and other root vegetables, many types of peelers have been commercialized and improved, making them very easy to use.
However, for peels of spherical fruits, vegetables, etc., it is still in a state where it is necessary to rely on skilled artisan knives and knives. It is easy, time consuming, peeled fruits and vegetables do not look good and are dangerous.
Also, if you use a fruit knife or kitchen knife incorrectly, it can become a weapon, so be careful when carrying it. In particular, it is forbidden to carry on an aircraft and is not suitable for carrying on a trip.

So far, several proposals have been made for peelers dedicated to peeling fruit and vegetables, but this is not satisfactory.
One example is Japanese Utility Model Application Publication No. 55-68909. According to this device, as shown in FIG. 10A, an elliptical hole 13 is provided at the center of a substrate 11 formed in a clover shape having two pairs of arc-shaped holding sides 12A, 12A, 12B, 12B. A fruit peeler is disclosed in which a blade 15 having a slope 14 is provided on the inner periphery of the hole.
Further, as shown in FIG. 10B, a modification in which a pattern 16 is provided by extending one side of the substrate 11 is also disclosed.

Since the peeler according to the first conventional example does not have a blade for cutting or cutting the peeled fruit or vegetable, it is not satisfactory when it is portable for travel.
As a second conventional example, Japanese Utility Model Application Publication No. 51-68254 is available. According to this device, as shown in FIGS. 11A to 11C, holes 26, 26 ′, 26 ″ are provided in the central portion of the base portion 22 of the plastic substrate 21 provided with a handle, and a blade 23 is provided on one side or inner periphery of the hole. , 23 ', 23 "are disclosed.
In addition, a configuration in which a blade 24 or 25 for cutting or cutting is provided on the side edge or end of the handle is also disclosed. (See FIG. 11A)
Since the peeler according to the second conventional example is provided with a cutting or cutting blade at the handle portion, in the case of a skinning operation, there is always a fear of cutting by the blade of the handle portion. Therefore, when not in use or when being carried, it is inevitable that the blade of the handle is housed in some protective cover so that the blade portion is not exposed. For this reason, it is not something that can be carried safely on travel.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a metal flat plate 30 used in this embodiment. The flat plate 30 is made of a rust-free metal material. For example, a SUS310 or SUS320 SUS material having a thickness of 0.5 mm is suitable. The flat plate 30 has a rectangular shape having a pair of short sides 31 and 32 having a length (a) and a pair of long sides 33 and 34 having a length (b). For example, a = 48 mm and b = 76 mm.
The SUS flat plate 30 is located at a distance (e) from one short side 31 of the pair of short sides 31 and 32, closer to the short side 31 than the middle, and half the short side length. A circular hole 35 having a diameter of about 20 to 30 mm is formed at the position (a / 2). A peeling blade 36 having an inner blade angle of 10 ° is formed in a circle on the inner peripheral edge of the circular hole. For example, e = 20 mm and the diameter of the circular hole is 22 mm. The distance (e) may be a position (b / 2) that is half the length of the long side. However, when viewed from the viewpoint of how to apply the force of the skinning operation, the distance (e) is a position that is biased toward one short side 31. Is more desirable.
After forming the circular hole 35, the blade 36 has an inner peripheral edge extending from one plate surface side of the flat plate 30 (the upper surface side of the paper surface in FIG. 1; this surface is hereinafter referred to as the front surface side of the flat plate 30). It is cut into a circle so as to be a cutting edge, and the obtained cutting edge portion is burned and formed. In this example, the stripping blade 36 is formed in a flat plate with a circular hole and formed on the entire circumference of the inner peripheral edge. However, it is not necessarily limited to a completely circular shape, but an oval or square annular blade. Alternatively, a blade provided only on a part of the inner peripheral edge of the annular hole may be used.

Two corners formed by the other short side 32 of the rectangular flat plate 30 with both long sides 33 and 34 are cut off by (c) × (d), respectively, and thereby the recessed side portions 37, 38, 39 and 40 are cut. have. For example, c = 8 mm and d = 8 mm.
The through holes 41 and 42 are provided in the corners after being cut off at a distance (f) from the long sides 33 and 34 and at a distance (g) from the recessed sides 37 and 39. For example, f = 3 mm and g = 3 mm.
On one long side 33, a sawtooth cutting or cutting blade 43 is formed from the short side 31 to the distance (h). As a result, a removal protrusion 44 such as a potato bud or a damaged part of fruit is obtained at the intersection of the short side 31 and the blade 43. The cutting or cutting blade 43 is not necessarily a sawtooth blade but may be a simple straight blade. For example, h = 50 mm.

The intersection of the short side 31 and the other long side 34 is curved, for example, about 3R to prevent danger.
FIG. 2A is a plan view of the first bar handle 45 that is rotatably attached to the through hole 41. 2B is a side cross-sectional view of the rod handle 45 shown in FIG. FIG. 2C is a plan view of the second bar handle 46 attached to the through hole 42. 2D is a cross-sectional view of the rod handle 45 shown in FIG. 2A as viewed in the direction AA ′. FIG. 2E is a cross-sectional view of the rod handle 46 shown in FIG.

Each of these bar handles is obtained from a round bar of diameter (i) and length (j). Here, j> b. For example, i = 10 mm and j = 80 mm.
Each rod handle 45, 46 has a pivot hole 47, 48 of diameter (l) at a distance (k) from one end 45a, 46a. For example, k = 13 mm and l = 3.2 mm.
The holes 49 and 50 are formed coaxially with the pivot holes 47 and 48. For example, the diameter (m) is 7 mm, and the depth (n) from the upper surface is 3 mm.
A plane 45b, 46b perpendicular to the pivot holes 47, 48 is formed at a distance (o) from the upper surface of each bar handle, and from positions 45g, 46g at a distance (p) from the center of each pivot hole 47, 48, Protrusions 45d and 46d having a length of (q) are formed to the other ends 45c and 46c of the rod handles 45 and 46, respectively. For example, o = 6 mm, p = 3 mm, and q = 64 mm.

The distance between the inner walls 45e, 46e of each protrusion and the centers 45f, 46f of each bar handle is (r). Moreover, the end surfaces near the pivot of each protrusion are set to 45 g and 46 g. Further, the height of each protrusion from the flat surfaces 45b and 46b is defined as (s). For example, r = 3 mm and s = 2 mm.
3A-3E show a variation of the first and second bar handles 45,46. 2A to 2E are denoted by the same reference numerals and reference characters. In this modification, the upper surface portion of each bar handle is cut out so as to have surfaces 45h and 46h parallel to the planes 45b and 46b at a distance (o ′) from the planes 45b and 46b. Therefore, the through holes 49 and 50 are not formed. For example, o ′ = 4 mm.

3A to 3E, the first and second bar handles 45 and 46 of the modification shown in FIG. 3A are combined with the rectangular flat plate 30 shown in FIG. Shown in FIG. 4A is a plan view of a first embodiment of the fruit knife according to the present invention. FIG. 4B is a side view thereof. FIG. 4C is a front view thereof.
When assembling, the pivot hole 47 of the first rod handle 45 and the through hole 41 of the flat plate 30 are aligned so that the rod handle can be smoothly rotated without rattling by the bolt and nut or the caulking pin 49a. Pivot. Similarly, the pivot hole 48 of the second rod handle 46 and the through hole 42 of the flat plate 30 are aligned with each other and pivotally attached by a bolt and nut or a caulking pin 50a.

At this time, is the distance (r) between the center 45f, 46f of each rod handle and the inner walls 45e, 46e of the protruding portion equal to the distance (f) from both long sides 33, 34 of the flat plate 30 to the through holes 41, 42? By largely setting r > f, the first bar handle 45 can be rotated counterclockwise until the long side 33 in FIG. 4A hits the inner wall 45e of the protrusion. Accordingly, the flat surface 45b covers and protects the long side 33 and the sawtooth cutting or cutting blade 43 formed on the edge thereof.
Similarly, the second bar handle 46 can be rotated clockwise until the long side 34 in FIG. 4A hits the inner wall 46e of the protrusion. Thereby, the plane 46b covers the long side 34 and protects it.

  In this way, the state in which the rod handles 45 and 46 cover the long sides 33 and 34 is referred to as a first state of the knife. When the handle of the knife of the present invention in the first state is grasped and the flat plate 30 is pressed against the peripheral surface of the fruit to be peeled, such as an apple, as shown in FIG. Since it enters into the circular hole 35 of the flat plate 30, the flat plate 30 is indicated by an arrow in the figure in the pressed state, and is slid on the surface of the fruit in the lateral direction from left to right, or the fruit is opposite to the arrow. The fruit 36 can be peeled off by the blade 36.

When the fruit knife 1 is in the first state, anti-slip protrusions 45j and 46j may be formed on the outer edges 45i and 46i of the bar handles 45 and 46, respectively. (See Figure 4D)
Since the skinning blade 36 is formed at the inner edge of the circular hole 35, the risk of cutting is lower than the risk when the cutting or cutting blade 43 is exposed, but it is safer. 4E and 4F, a ring cover 2 made of a thin metal plate or plastic material as shown in FIGS. 4E and 4F is attached to the flat plate 30 of the knife 1 in the first state shown in FIG. 35 may be protected. 4E is a plan view of the ring cover 2, FIG. 4F is a side view, FIG. 4G is a plan view of the fruit knife after the ring cover is mounted, and FIG. 4H is a front view thereof. In these drawings, 2a is a folded portion sufficient to cover the circular hole 35, and 2b is an engaging portion that engages with the short side 32 of the flat plate 30 with springiness.

When this ring cover 2 is attached to the flat plate 30 of the knife 1 in the first state shown in FIG. 4A, as can be seen from FIGS. 4G and 4H, the cover 2 can stop the rotation of the rod handle. You can carry it.
However, the fruit knife 1 in the first state can be carried in an appropriate case (not shown) regardless of whether or not the ring cover 2 is used.
When the fruit needs to be cut or carved after being peeled, the bar handle 45 of the fruit knife 1 in the first state of FIG. 4A is rotated clockwise in FIG. 4A around the bolt and nut or caulking pin 49a. The bar handle 46 is rotated counterclockwise in FIG. 4A about the bolt and nut or caulking pin 50a as a pivot, and the cutting or cutting blade 43 is exposed.

At this time, when cf = i / 2 is selected and p = g is selected, the side end 45i of the rod handle 45 abuts against the recessed side portion 38 of the flat plate 30, and the end surface of the protruding portion 45d is 45g. It abuts against the indented side 37 and further rotation is restricted. Similarly, the side end 46i of the bar handle 46 abuts on the recessed side portion 40 of the flat plate 30, and the end surface 46g of the protruding portion 46d abuts on the recessed side portion 39, and further rotation is restricted. This state is shown in FIGS.
This state in which the both-bar handles 45 and 46 are rotated 180 degrees clockwise and counterclockwise from the first state and the further rotation is limited is defined as a second state of the knife.

The fruit knife 1 in the second state can cut or cut fruit or the like as shown in FIG. 7 by using both cutting and cutting blades 43 by grasping both bar handles. In addition, it is possible to use the protrusions 44 of the blade 43 to remove and remove potato buds or damaged parts of fruits.
In this way, the fruit knife according to the present invention is provided with a peeling circular blade 36 on a thin plate of a rust-free metal having a rectangular shape, and a cutting or cutting blade 43 is provided on one edge of its long side, Further, since the pair of rod handles are pivotally attached, the cutting or cutting blade 43 is exposed only when it is used, and is always protected by the rod handle at all other times, which is extremely safe.

In the above description, the rod handles 45 and 46 are described as being formed from round bars having a diameter (i), but the present invention is not limited to this. For example, as shown in FIGS. 8A to 8E, a rod having a rectangular cross section of (o + s) × i can be formed in the same manner as in FIGS. 3A to 3E. In this case, the same parts as those in FIGS. 3A to 3E are denoted by the same reference numerals and the same reference characters.
9A and 9B, a slit 30a is formed in the vicinity of the short side 32 of the flat plate 30, and the short side 32 is bent obliquely upward from the surface side of the flat plate 30 into a "<" shape. The rectangular inner blade 30c is formed on the portion 30b that is raised up diagonally so that the inner edge of the slit becomes the blade edge from the surface side. As a result, it is possible to more easily carry out the work of peeling the peeled cylindrical or conical vegetables such as radishes and carrots. 9A is a plan view of the vicinity of the short side 32 of the flat plate 30. FIG. FIG. 9B is a front view thereof.

The fruit knife of the present invention uses a ring blade formed on the entire inner edge of a hole formed in a metal flat plate or a part thereof as a peeling blade 36, and presses it against the surface of a spherical fruit or the like, If the blade and the fruit are moved in the opposite directions in this state, the skin can be peeled off. When moving the blade, the blade is safe because it is not exposed outward.
However, when the skin is peeled off, the circular blade portion is blocked with fruit or the like, so that the finger or the like does not enter the circular blade, which is also safe in this respect.
Further, a cutting or cutting blade 43 is formed at one corner of one long side and one short side of the rectangular flat plate, and a pair of bar handles are formed at the corners between the other short side and both long sides of the rectangular flat plate. Because it is pivotally attached and the bar handle is in a position where the long side is not exposed during the peeling operation, and the bar handle is rotated to a position where the long side is exposed only during the cutting or carving operation, During the peeling operation, the operator has no risk of cutting with the cutting or cutting blade, and during the cutting or cutting operation, the operator can operate by gripping the handle, so that the cutting or cutting blade is used. There is no risk of incision by the blade, and it is extremely safe.

Also, the removal protrusions such as potato sprouts or damaged parts of the fruit provided at the tip of the cutting or cutting blade are exposed together with the cutting or cutting blade, so that during the peeling operation There is no risk of the operator being injured by such protrusions. In other words, it can be handled safely by anyone, so it can be used conveniently by carrying it on a trip or camping.
In addition, when not in use or when being carried, the cutting and separating blades and protrusions are not exposed outwardly, so that no harm can be given to people. In other words, it cannot be used as a weapon. This is also safe.

To summarize the features of the present invention:
-The flat plate 30 and the rod handle forming the blade are manufactured separately and assembled. Therefore, the cutting or separating blade 43 can be added to the rectangular flat plate 30 including the annular skinning blade 36 without changing its shape and size.
-During the skinning operation, the cutting or cutting blade 43 is covered with the rotating bar handle, which is safe. Further, in the peeling operation, the rod handle serves as a handle to be gripped by the fingertip, so that the contact area with which the finger hits increases, and the knife is difficult to slip when peeling.
During the cutting or cutting operation, the rod handle serves as a knife handle, so that it is possible to work safely without grasping the cutting or cutting blade 43.
-When carrying, the rod handle covers the cutting or cutting blade 43 and is safe. Further, if a ring cover is used, the cover of the skinning blade 36 can be formed, and at the same time, rotation of the bar handle can be prevented, so that it is safer.
