Fork having tine with retaining feature

摘要

Conventional multi-tined implements such as cutlery and serving forks, pitchforks and front-end loader machine forks, all have smooth tine surfaces from which the respective items being picked up and transferred by a user may unintentionally slip off and cause harm. All such implements are provided enhanced ability to retain their respective loads during their intentional transfer by a user by the provision of a plurality of topographic discontinuities on selected load-contacting surfaces of their tines. These topographic discontinuities include small barb-like elements generated by wedge-shaped recesses extending into the tines and/or by barb-like projections extending from the tines into inter-tine gaps between adjacent tines. On thus improved food-handling implements all intersections, corners, edges and points incidental to formation of any topographic discontinuities are smoothed out to prevent physical harm to users.

主权项

1. In a dining fork that has a handle at a rear end and a head at a forward end, the head including a plurality of spaced-apart and longitudinally-aligned tines having respective distal ends shaped for insertion into an item of food to engage with and transfer the same, wherein the improvement comprises:
a topographic discontinuity provided to a first one of said tines on a first side surface thereof, the first side surface facing an opposing side surface of an adjacent second one of said tines, wherein the discontinuity extends into the first side surface to a predetermined depth and comprises a recess extending between a first location and a second location, wherein the first location is closer to the distal end of the first tine than the second location, wherein the the recess has a shape defined by a first surface intersecting a second surface at a first angle smaller than 90 degrees, wherein the first surface intersects the first side surface at the first location at a second angle less than 90 degrees, and wherein the intersection of the first surface and the first side surface defines an edge that is inclined with respect to a line orthogonal to the longitudinal direction of the tine.
