Abstract
An improved actuation device for a piezoelectric lighter having an axially aligned hammer and a piezoelectric impact terminal. An elastic retention member engages the hammer as a bias force is imposed thereon. The actuation member is adapted to release the hammer by a displaceable actuation switch after the hammer passes through a predetermined distance thereby causing the hammer to strike the piezoelectric impact terminal.
Claims4
A piezoelectric lighter which comprises:
- a. a piezoelectric ignition unit having an impact terminal;
- b. a displaceable actuation switch;
- c. a first biasing means for providing a biasing force to return the actuation switch to its original position when displaced;
- d. a movable hammer positioned to strike said impact terminal;
- e. a second independent biasing means for providing a biasing force to displace said hammer;
- f. said hammer, impact terminal and second biasing means being in axial alignment;
- g. said hammer and second biasing means being positioned in a displaceable retention member adapted to be displaced by said actuation switch;
- h. said hammer and actuation switch being detachably connected by an elastic retention member;
- i. said elastic retention member comprises a lug adapted to engage said hammer and to displace the hammer against the second biasing means in response to the actuation switch;
- and
- j. means for releasing the elastic retention member when the hammer reaches a predetermined position thereby causing the hammer to strike the impact terminal.

A piezoelectric lighter which comprises:
- a. a piezoelectric ignition unit having an impact terminal, said ignition unit being positioned within a hollow elongated housing, said unit further characterized in having piezoelectric material positioned between a pair of support disks, one of said disks being positioned against said impact terminal and adapted to provide a negative pole conductor, the other disk being positioned against a metallic absorption plate which is connected to a positive electrode;
- b. a displaceable actuation switch;
- c. a first biasing means for providing a biasing force to return the actuation switch to its original position when displaced;
- d. a movable hammer positioned to strike said impact terminal;
- e. a second independent biasing means for providing a biasing force to displace said hammer;
- f. said hammer, impact terminal and second biasing means being in axial alignment;
- g. said hammer and actuation switch being detachably connected by an elastic retention member;
- h. said elastic retention member adapted to displace the hammer against the second biasing means in response to the actuation switch;
- and
- i. means for releasing the elastic retention member when the hammer reaches a predetermined position thereby causing the hammer to strike the impact terminal.
