Definitions

  • the present invention relates to a cutting instrument having a disassemblable handle and a finger-rest member, a handle thereof, and a finger-rest member used therefor.
  • a conventional cutting instrument such as a kitchen knife has a structure in which a blade is integrally fixed to a handle so that the instrument cannot be easily disassembled at home.
  • a handle in which a core is fixed to side plates at a predetermined distance in Japanese Utility-Model Registration No. 3034863. According to this proposal, there is an advantage that a handle can be disassembled for washing even at home.
  • the cutting instrument of the present invention includes: a blade provided with at least one hole in a core; and a handle in which the core is integrated with side plates disposed on both sides thereof via spacing chips, wherein a finger-rest member extends from a part between the core and the side plates to cover a part of a ridge portion of the blade, and the core is integrated with the side plates by a convex portion provided on one of the side plates so as to be inserted into at least one hole provided in the core, a concave portion provided on the other side plate so as to be engaged with the convex portion, and a fixing member inserted into an engaged region between the convex portion and the concave portion. Because of this structure, a finger tip will no ache even after cooking for a long period of time, and the handle can be disassembled.
  • the finger-rest member may be fixed to the blade or detachably provided at the blade.
  • the finger-rest member is detachably provided, it can be used only when required and washed easily.
  • the finger-rest member has a base that enters between the side plates, and the base has a hole engaged with an axis portion for fixing a finger-rest member provided inside of the side plate. Because of this, the base of the finger-rest member is accommodated between the core and the side plates, and can be rotated about axis portions for fixing.
  • a cut-away portion is partially provided at the hole of the base of the finger-rest member, the axis for fixing a finger-rest member has a circular or elliptical cross-section, and the finger- rest member is rotatable and detachable. Because of this, the finger-rest member can be easily rotated and detached.
  • the finger-rest member has a groove in a portion that comes into contact with the ridge portion of the blade. Because of this, the finger- rest member can stably cover the ridge portion of the blade.
  • the finger-rest member has an arm that sandwiches the core and enters between the side plates when the finger-rest member comes into contact with the ridge portion of the blade. Because of this, the finger-rest member is tightly fixed without idling sideways.
  • a fixing member inserted into an engaged region between the convex portion and the concave portion is buried in the side plates, and covered with a cap. Because of this, the outer surfaces of the side plates forming the handle become smooth, which realizes easy handling.
  • the side plates and the finger-rest member are made of resin.
  • the side plates and the finger-rest member made of resin are clean and provide a smooth texture.
  • the use of resin can reduces cost. For example, an injected molding can be used.
  • the side plates are made of transparent resin.
  • transparent resin makes it easy to check for contamination.
  • the handle of the present invention is used for any of the above- mentioned cutting instrument.
  • the handle includes side plates disposed on both sides of a core at a distance; a convex portion provided on one of the side plates for insertion into at least one hole in the core; a concave portion provided on the other side plate engaged with the convex portion; and a space for a fixing member inserted into an engaged region between the convex portion and the concave portion, wherein there is provided means for fixing a finger-rest member that extends from a part between the core and the side plates and covers a part of a ridge portion of a blade.
  • a finger-rest member of the present invention is used for any of the above-mentioned cutting instrument, wherein the finger-rest member extends from a part between a core and side plates and covers a part of a ridge portion of a blade, and has an arm that sandwiches the core and enters between the side plates when the finger-rest member comes into contact with the ridge portion.
  • FIG. 1 is a front view of a cutting instrument of one example according to the present invention.
  • a cutting instrument 1 consists of a blade 2, a handle 3, and a finger-rest member 10.
  • the blade 2 has an edge 4 and a ridge portion 5, and preferably has ribs 6 on its side.
  • the ribs 6 are not required. However, when they are provided, vegetables with a large content of water, such as a cucumber, an onion, and a potato, can easily come off the blade 2, when being cut for cooking.
  • a side plate 16 of the handle 3 is made of acrylic transparent resin, so that a core 18 and fixing portions 7, 8, and 9 can be seen. A method for fixing the fixing portions 7, 8, and 9 will be described later with reference to Figures 3, 5, and 6.
  • the finger-rest member 10 has a base 11 and an arm 15.
  • the base 11 has a hole 12 that is engaged with an axis portion 14 for fixing a finger-rest member provided inside of the side plate. This enables the finger-rest member 10 to rotate. Furthermore, when a cut-away portion 13 is partially provided at the hole 12, the finger-rest member 10 becomes detachable.
  • the arm 15 is accommodated inside the side plate 16.
  • the arm 15 has a gap corresponding to the thickness of the core 18 so as to tightly sandwich the core 18. Therefore, when the finger-rest member 10 is pressed with a finger from above, it is fixed without moving sideways.
  • the finger-rest member 10 covers 5 to 50%, more preferably 10 to 40% of a length of the ridge portion 5, extending from the end of the handle 3 to the ridge portion 5. Furthermore, the finger-rest member 10 preferably covers 5 to 30%, more preferably 7 to 15% of the upper side of the handle 3.
  • Figure 2 shows a state immediately before the finger-rest member 10 rotated upward is detached.
  • the axis portion 14 for fixing a finger-rest member provided inside of the side plate, has an elliptical shape in cross-section. Therefore, the finger-rest member 10 can be easily pulled out by rotating it so that the portion with a shorter diameter of the axis portion 14 comes into contact with the cut-away portion 13 at the end of the hole 12. If a part of the hole 12 is slightly rendered flat, when the axis portion 14 is inserted into the cut-away portion 13 for rotation, the end of the hole 12 first opens slightly outward. When the finger-rest member 10 is further rotated, the hole 12 returns to the original state to be stabilized.
  • FIG. 3 is an exploded view of the cutting instrument.
  • Convex portions 25, 27, and 29 on the first stage of a side plate 17 have a height of about 3 mm.
  • Convex portions 26, 28, and 30 on the second stage of the side plate 17 also have a height of about 3 mm.
  • Three holes 19, 20, and 21 are formed in the core 18 of the cutting instrument 1.
  • the convex portions 26, 28, and 30 on the side plate 17 are pressed in the holes 19, 20, and 21, respectively, so as to project by about 1 to 2 mm frontward from the core 18 in the drawing.
  • the projecting portions are fit in the concave portions 22, 23, and 24 on the side plate 16.
  • the concave portions 22, 23, and 24 are formed so as to project by about 3 mm from the side plate 16 to the core 18.
  • a bolt 33 is inserted through a hole 31 at the center of the side plate 16, and passed through a hole 32 at the center of the side plate 17 to be screwed with a nut 34.
  • the nut 34 is accommodated in a hexagonal cylinder space formed in the side plate 17 so as not to idle.
  • the bolt 33 and the nut 34 are covered with caps 35 and 36 from outside, respectively. If the cap 35 is provided with a pinhole 37, the handle can be easily disassembled simply by inserting a pointed member into the pinhole 37, which is convenient.
  • a cutting instrument can be assembled in which a space of about 3 mm is provided between the core 18 and the side plates 16 and 17.
  • FIG. 4 is a plan view of a cutting instrument of one example according to the present invention.
