ABSTRACT:

CROSS REFERENCE TO RELATED APPLICATIONS, IF ANY
None
BACKGROUND OF THE INVENTION AND PRIOR ART
The present invention relates generally to knives and, more particularly, to foldable pocket knives which may be camouflaged to appear as a fountain pen or ball point pen or the like. In general, foldable pocket knives include a handle having a blade cavity therein, the blade being pivotally affixed to the handle and received in the cavity which is defined between spaced handle side portions. A spring retainer is usually also affixed in the handle and moves in the general plane in which the blade pivots, to the spring bias and hold the blade in a blade deployed or stored position. A well known disadvantage of knives of this general type is the difficulty in quickly grasping and opening the blade. Usually, the blade is provided with a fingernail receiving groove being the only portion of the blade which is exposed when the blade is in its stored position. The difficulty in opening the blade is the result of the relatively large blade opening spring force which must be overcome merely by insertion of a single fingernail into the blade opening groove.
Other prior art types of knives are designed to open more quickly but are not always legal such, for example, as spring actuated switch blade knives which rely upon a spring to bias the blade to the deployed position upon actuation of a push button or the like.
OBJECT OF THE INVENTION
It is the primary object of the present invention to provide a knife which may be quickly opened and closed without the above disadvantages and without grasping the blade itself.
SUMMARY OF THE INVENTION
The present invention accordingly provides a pocket knife comprising:
a) an elongate handle body having a full handle portion and a stationary partial handle portion;
b) a moveable partial handle portion connected to said stationary partial handle portion for movement around a pivot axis proximate one end of said body, said first and second partial handle portions defining a blade storage space therebetween;
c) a blade connected to each of said partial handle portions for movement around said pivot axis proximate said one end of said body, said moveable partial handle portion being positionable alongside said stationary partial handle portion in a first position with said blade stored in said space;
d) first retainer means for releasably affixing said moveable partial handle portion to said blade as said second partial handle portion and blade are pivotally moved as a unit in a blade opening direction from said first position to a blade deployed position; and
e) second retainer means for releasably affixing said blade to said body in said blade deployed position as said moveable partial handle portion is further moved in said blade opening direction to said first position alongside said stationary partial handle portion with said blade operably deployed.
As used herein, the term “full handle portion” refers to the portion of the knife handle which is not formed in part by a moveable partial handle portion.
