  • conventional and existing handle of cutlery may be fitted with at least two retractable wedges. Each of the wedges are hinged on the side of the handle and openable in opposite directions such that the user may grip the cutlery on one wedge with the web spaces between the thumb and index finger as well as on the other wedge with the palmer surface of the upper middle finger. The user may rest the inter-digital area of his index finger on the upper edge of the handle.
  • the handle comprises a tapering head portion, and an intermediary portion and a tail portion where the head portion has a concave rest portion for accommodating the interdigital area of the index finger, the inter-mediary portion having a concave hook area at the lower front for accommodating the palmer surface of the upper middle finger, and the tail portion having a concave hook area at the lower rear for accommodating the web spaces between the thumb and index finger such that the user may grip the cutlery ergonomically.
  • FIG. 1 illustrates a first embodiment of the present invention where the handle of cutlery may be fitted with at least two retractable wedges in opposing direction for an ergonomic grip.
  • FIG. 2 is a left side elevational view of a knife fitted with an ergonomic handle according to a second embodiment of the present invention.
  • FIG. 3 is a front left side perspective view of the embodiment in accordance to FIG 2.
  • FIG. 4 is a left elevational view of a fork fitted with an ergonomic handle according to a second embodiment of the present invention.
  • FIG. 5 is a front left side perspective view of the embodiment in accordance to FIG 4.
  • FIG.6 illustrates the 'Dinart' grip of a fork or a knife fitted with an ergonomic handle according to the second embodiment of the present invention.
  • FIG.7 illustrates a conventional grip of a fork fitted with an ergonomic handle according to the second embodiment of the present invention.
  • FIG.8 illustrates a conventional tableware grip of a fork or a knife fitted with an ergonomic handle according to the second embodiment of the present invention.
  • FIG. 1 illustrates a first embodiment of the present invention where the handles of conventional cutlery are modified.
  • a top plan view of a modified spoon 1 is illustrated in FIG. 1 where it appears like a normal spoon.
  • the side elevational view of a modified knife 2 is shown having a handle according to a first embodiment of the present invention where at least two retractable wedges 4 and 5 are hinged at 6 on the side of the handle.
  • the wedges 4 and 5 are retracted and appears just like a typical handle of a conventional knife.
  • the wedges are lowered.
  • the space formed by the lowered wedges and the underside of the handle 3 allows the user to grip the handle 3 with the web spaces between the user's thumb and middle finger at wedge 5 and the palmer surface of the upper middle finger at wedge 4 respectively.
  • the inter-digital area of the user's index finger may rest on the upper edge of the handle 3.
  • this grip shall be referred to as the 'Dinart' grip.
  • FIG 1 a top plan view of a fork is also shown with the wedges being retracted into the respective slots 8 and 9.
  • the handle of the present invention as illustrated in the first embodiment in FIG 1 allows the user to harness strength efficiently from the wrist (not shown), the fingers (shown in FIG 6) and the forearm to provide the downward force and the sawing motion to press and cut food placed on a horizontal surface.
  • the full grip and the upper arm (not shown) as illustrated in FIG 8, the present invention utilizes and applies forces more efficiently.
  • FIG. 2 is a left side elevational view of a knife fitted with an ergonomic handle according to a second embodiment of the present invention.
  • the handle 10 comprises a tapering head portion 12, an intermediary portion 13, and a tail portion 14.
  • the head portion 12 features a concave rest portion 15 for allowing the inter-digital area of the index finger to rest thereon.
  • the head portion 12 is applicable for the conventional tableware grip.
  • the intermediary portion 13 has at least one supporting area 16 for allowing the inter-digital area of the thumb to press against the handle.
  • the handle 10 is symmetrical such that left or right handed person may use the same cutlery.
  • the lower forward section of the intermediary portion 13 features at least one concave hook 17 for accommodating the palmer surface of the user's middle finger.
  • FIGS 2 and 3 shows the handle being fitted with a knife, it should be understood by one skilled in the art that other utensils and cutlery can be mounted with the handle of the present invention.
  • FIGS 4 and 5 shows a fork being fitted with an ergonomic handle of the present invention.
  • FIG.6 illustrates the 'Dinart' grip of a fork or a knife fitted with an ergonomic handle according to the second embodiment of the present invention.
  • the web spaces between the thumb and index finger wraps around the concave hook section 18 which provides a forward push and pivotal motion for the vertical movements of the cutlery as shown in FIG 6.
  • the inter-digital area of the index finger rests on the rest section 15 of the handle 10; this section facilitates the user's downward press on the cutlery.
  • the user's middle finger wraps around the concave hook section 17 for facilitating the user's pulling, upward and downward force on the cutlery.
  • the present invention allows better and efficient application of force on utensils and cutlery, but it would also allows the user to develop better posture.
  • the user holds the cutlery with palm facing each other without ever lifting his shoulders and/or arm while cutting food.
  • the user In contrast with the conventional grip as shown in FIG 8, the user generally lifts up the upper arms sideways for pressing or exerting force on the cutlery thereby requiring more elbow space.
  • cramped dinning quarters such as in an aircraft cabin, it would be inconvenient for users who have habits of using cutlery in such a manner.
  • FIGS 6, 7 and 8 also highlight the versatility of the ergonomic handle of the present invention: regardless of what type of grip the user is accustomed to, the ergonomic handle may be used. However, the most comfortable way of using the handle is the 'Dinart' grip. Over time, the user adopts the preferred grip as it exerts the least stress on the joints while taking up the least elbow room. Above all, the handle of the present invention promotes good posture in using cutlery.
