connecting said knife and fork together during use thereof.
Description
FIELD OF THE INVENTION
This invention relates to a knife and fork combination and more
particularly to such a combination for juvenile training.
It is a principle object of this invention to provide a knife and
fork combination for training a young child in the use of a knife
and fork for cutting food and for facilitating cutting while at the
same time training the child.
SUMMARY OF THE INVENTION
In general the invention features a knife and fork adapted for
interconnection. The knife includes an elongated slot parallel to
and along the length of the cutting edge thereof and a slide member
having enlarged ends slidably positioned in the slot. The fork
includes a slot elongated in the direction of the handle having an
enlarged end adjacent the handle, for insertion of an enlarged end
of the slide member, and a portion of predetermined width smaller
than the enlarged ends for retaining the slide member therein. With
the knive and fork thus interconnected, cutting may proceed
normally with the slide member holding the knife and fork together
in proper relationship. Preferably the slide member is cylindrical
in form and the major extent of said fork slot is of said
predetermined width. Also, in a preferred embodiment the slots are
so interrelated that the cutting edge of the knife is moveable
beyond the ends of the fork tines when the knife and fork are
interconnected.
Other objects, features and advantages of this invention will be
apparent to those skilled in the art from the following detailed
description of a preferred embodiment thereof taken together with
the accompanying drawings in which:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an isometric view of a disconnected knife and fork
according to the invention;
FIG. 2 is an elevation of the knife and fork of FIG. 1 connected
and ready for use; and
FIG. 3 is a sectional view along the line 3--3 of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, fork 10 comprises an elongated handle 12, a
plurality of tines 14 extending from one end thereof in the
direction of elongation of the handle and an integral
interconnecting web 16. A longitudinally extending fork slot 18,
longitudinally aligned with handle 12 and tines 14, is provided in
web 16 of fork 10. Slot 18 has a predetermined width at end 20
thereof adjacent tines 14. At the other end 22, slot 18 is enlarged
to a width greater than the said predetermined width. In the
preferred embodiment shown, slot 18 has a keyhole shape with a
uniform predetermined width from end 20 adjacent tines 14,
throughout the major extent of its length, until it reaches end 22,
provided with an enlarged generally circular enlarged aperture
thereat.
Knife 30 comprises a handle 32 and a blade portion comprising a
cutting edge 34 on one elongated side edge of an elongated blade
web 36. An elongated knife slot 38 is provided in web 36 generally
parallel to and coextensive with the length of cutting edge 34. The
knife slot 38 has a width narrower than the enlarged width of fork
slot 18 adjacent end 22, preferably equal to said predetermined
width of slot 18 adjacent end 20.
Positioned in knife slot 38 and extending therethrough is a slide
member 42 having a maximum dimension transversely of slot 38
slightly smaller than the width of knife slot 38 and said
predetermined width of fork slot 18 for a slip fit therein. Spaced
apart, a distance slightly greater than the aggregate thickness of
knife and fork 10, 30 adjacent their respective slots 18, 38, on
slide member 42 are enlarged ends 44, 46 larger than the width of
knife slot 38 and said predetermined width of fork slot 18 and
smaller than the enlarged width of fork slot 18 adjacent end 22
thereof. In the preferred embodiment, best shown in FIGS. 2 and 3,
slide member 42 comprises a cylinder and the enlarged ends 44, 46
thereof comprise circular flanges at the cylinder ends.
As shown in FIGS. 2 and 3, the elongated edge 40 of knife slot 38,
remote from cutting edge 36, is spaced from the cutting edge 36 by
a distance at least equal to and preferably greater than the
aggregate of the distance from the ends of tines 14, remote from
fork handle 12, to the adjacent end 20 of fork slot 18 plus the
width of slide member 42 transversely of knife slot 38. Edge 40,
however, is spaced from cutting edge 34 a distance less than a
distance from the ends of tines 14 to the remote end 22 of fork
slot 18.
In use for cutting, one flange 44 or 46 of slide member 42 is
inserted through enlarged end 22 of fork slot 18. Knife 30 is then
moved downwardly to engage fork slot 18 at its predetermined width.
Knife 30 may then be reciprocated longitudinally for cutting. When
cutting is complete, knife 30 is disengaged from fork 10 by
removing flange 44 or 46 from slot 18 through enlarged end 22
thereof.
Advantageously for children, knife 30 will not slip away from fork
10 during cutting due to the engagement of flange 44 or 46 with
fork 10. On the other hand, the elongated slotting of the knife
permits normal cutting action and the elongated slotting of fork 10
accommodates the thickness of the item being cut. Knife 30 is
readily engaged with fork 10 for cutting use and is readily
disengaged for normal use of the fork.
Other embodiments of this invention will occur to those skilled in
the art which are within the scope of the following claims.
