Definitions

  • the present disclosure relates generally to cutting instruments with blades, and more particularly, but not necessarily entirely, to cutting instruments with multiple blades.
  • Modern cutting instruments for cutting objects typically comprise a single blade extending from a handle A user may grasp the handle to thereby control the movement of the blade and to impart cutting motions onto the blade itself.
  • Previously available blades may be formed from a wide variety of materials, including metals and plastics.
  • previously available handles may be formed from a wide range of materials as well, including metals, wood and plastics
  • Some previously available cutting instruments have blades integrally formed with the handles, such as plastic knifes and butter knifes.
  • the '383 Patent teaches a design for a utensil for cutting food into child-sized bites.
  • the utensil includes a plurality of blades arranged in a side-by-side arrangement. The top edge of the blades are coupled to a bottom surface of a disk-shaped body. While apparently an improvement over a conventional design, the disk-shaped body appears difficult to grasp as no clear handle is present Further, the blades on the utensil appear to be fixed into place and do not appear to be removable or adjustable, thus the width of the slices cut by the utensil does not appear to be variable. This is disadvantageous, since often times a user may wish to increase or decrease the width of the slices.
  • FIG. 1 is a schematic view of a cutting apparatus made in accordance with the principles of the present disclosure

  • the blades 12, 14, 16 and 18 may be formed from plastic or metal depending upon the intended use of the apparatus 10. Plastic maybe desirable due to its low cost and ease of manufacture. However, metal maybe utilized if the strength of the blades 12, 14, 16, and 18 is at issue. For example, plastic may be utilized to form the blades 12, 14, 16 and 18 if the apparatus 10 is only intended to cut soft items, such as toast or dough. If, on the other hand, the blades 12, 14, 16 and 18 are intended to cut tough or fibrous items, such as meat or vegetables, metal may be required to form the blades 12, 14, 16 and 18.

Abstract

La présente invention concerne un appareil de coupe à lames multiples qui sert à couper en tranches des objets, tels que des aliments. Les lames de l'appareil peuvent passer d'une position de coupe à une position de libération. En position de coupe, les lames sont capables de couper efficacement des objets en petits morceaux. En position de libération, toute matière coincée entre les lames tombe d'elle-même. Ainsi, un utilisateur n'a plus besoin de retirer manuellement toute matière coincée entre les lames. Un utilisateur peut utiliser un ou plusieurs leviers répondant à la force qu'il exerce pour que les lames passent de la position de coupe à la position de libération. Un élément souple peut fournir une force de restauration afin de permettre aux lames de revenir en position de coupe.
