DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling blade used for a peeling tool for peeling spherical fruits such as apples and pears or columnar root vegetables such as radishes and carrots.

[0002]

Heretofore, as shown in FIG. 9, the skinning device X ₁ that is used to come stripping of a cylindrical object to be peeled and Z, such as radish and carrot are commercially available. This conventional peeling tool X
₁ is to form bifurcated projections 102, 102 at the front end of a base (handle) 101,
A peeling blade 103 is attached between the two.

[0003] peeling blade 103 used in the stripping tool X ₁ in FIG. 9, as shown in FIG. 10, penetration of the cutting edge 131a in contact with the blade portion 131 having a predetermined length on the surface of the object to be peeled and Z A gap 133 is provided between the guard portion 132 and the gap portion 133 to limit the depth of the skin.
34 and 134 are formed. The surface of the blade portion 131 and the surface of the guard portion 132 are bent at an angle of about 45 ° as indicated by reference character a. The total length of the peeling blade 103 is 6
The length of the cutting edge 131a is about 50 mm.
In addition, in this peeling blade 103, the blade portion 131 and the guard portion 13
The interval of the gap 133 between the two is made smaller gradually from one end side in the length direction (the right end side in FIG. 10) to the other end side. That is, in the peeling blade 103, has become the width W ₂ of the narrow portion 133b of the left end portion width W ₁ of the wide portion 133a of the right end of about 5.8mm is about 2.2mm in the gap 133,
It gradually narrows from the right end to the left end. The cutting edge 131a of the blade 131 and the inner edge 132a of the guard 132 are each straight.

[0004] The peeling blade 103 shown in FIG. 10 has its left and right shafts 134, 134 as shown in FIG.

The stripping device X ₁ in FIG. 9 is used to come stripping primarily cylindrical object skinning material Z, the by pulling the cutting edge 131a linearly in a state pressed against the surface of the skinning material The skin can be peeled in the length direction. When the peeling tool Z is used on the side of the gap wide portion 133a of the peeling blade 103, the blade edge 131a penetrates deeply into the skin of the material Z to be peeled, and the wide area is peeled off at once (such as radish). Conversely, when the gap narrow portion 133b of the skin peeling blade 103 is used, the blade edge 131a enters the skin of the skin peeling material Z shallowly, so that the narrow area can be peeled off. Suitable for small-diameter like burdock).

[0005]

[SUMMARY OF THE INVENTION Incidentally, the skinning device X ₁ in FIG. 9 using the peeling blade 103 of Figure 10 is intended to be used primarily for peel skin cylindrical root vegetable Z in the longitudinal direction However, because the surface of the skinned object Z is a convex peripheral surface,
There is a disadvantage that the stability at the time of peeling is poor. That is, in the peeling blade 103, the cutting edge 131a and the inner edge 132a of the guard portion 132 are each straight, and when the skinning blade 103 is applied to the surface of the material Z, the cutting edge 131a and the guard portion inner edge 32a are formed. The length in contact with the surface of the material to be peeled is shortened, and the skinning blade 103 is easily kneaded left and right. Also, if the gap of the gap 133 between the blade portion 131 and the guard portion 132 is gradually reduced from the one end 133a to the other end 133b, the load on the wide portion of the gap 133 is larger than that on the narrow portion at the time of peeling. Therefore, an action of tilting the skin peeling blade 103 in the clockwise direction in FIG. 9 acts, and it becomes difficult to peel the skin in a straight line. In particular, the stripping device X ₁ in FIG. 9 using the peeling blade 103 in FIG. 10, for example in the case of performing the peeled spherical fruits such as apples and pears, since the surface of the debarking object is a spherical surface, peeling The blade 103 becomes more unstable.

The present invention has been made in view of the above-mentioned problems of the conventional peeling blades, and has made it possible for the blade edge to come into contact with the surface of the material to be peeled in a stable state, and to be able to peel a wide area at a time. It is intended to provide a skinned blade.

When peeling of a columnar root vegetable or a spherical fruit is performed using the peeling tool equipped with the peeling blade. The following functions are available. When peeling a cylindrical root vegetable with this peeling blade, peel the skin (convex peripheral surface) in the axial direction of the cylindrical root vegetable, and when peeling a spherical fruit with the peeling blade, peel the skin (spherical surface). Peel in the direction. In this peeling tool, when a peeling blade is applied to the convex peripheral surface or spherical surface of the peeling object, the blade edge of the blade portion and the guard portion simultaneously contact the surface of the peeling object, but the blade portion is concave. As a result, the blade edge of the blade portion comes into contact with the surface of the material to be stripped in a range longer than the linear blade edge, and the skin blade is stabilized.
Further, when the blade portion is formed into a curved shape as described above, the blade can be peeled off at a time at a wider width than that of the conventional straight blade portion, and the peeled skin can be made thinner even with such a wide width. The invention according to claim 2 of the present invention is directed to a peeling passage for peeling skin between a blade portion having a predetermined length and a guard portion which contacts the surface of the material to be peeled and limits the penetration depth of the blade edge. In the peeling blade provided with a gap, the inner edge facing the blade portion of the guard portion has a curved shape such that the gap between the gaps is wide at the center in the length direction and narrow at both ends. Features. For example, the interval at the center in the length direction in the gap is
It is preferable to set 3.5 to 5 mm and each interval between both ends to be about 2 to 3 mm.

The peeling blade according to the second aspect is also used as a peeling tool mounted on a base. The peeling tool equipped with this peeling blade has the following functions. That is, when this skinning blade is applied to the surface (convex peripheral surface or spherical surface) of the skinning object, the cutting edge of the blade portion and the inner edge of the guard portion simultaneously come into contact with the surface of the skinning material. Since the edge has a curved shape as described above (the center of the gap is wider than both ends), the blade edge penetrates deeply into the skin of the peeled material at a position closer to the center in the length direction of the blade portion and widens. Can be peeled. In addition, the curved shape of the inner edge of the guard portion is designed such that the gap is widened at the center portion in the length direction of the gap, so that the load applied to the blade edge when peeling the skin is made uniform left and right, and the stability is improved.

In the peeling blade according to the second aspect, if the configuration according to the first aspect (the blade portion is formed into a curved shape) is employed, a synergistic effect between the curved shape of the inner edge of the guard portion and the curved shape of the cutting edge is adopted. Thereby, the stability can be further increased and the skin can be widely peeled.
