Mechanical limiter device
First Claim
Patent Images
1. A mechanical limiter mechanism for use with an electrical device, comprising:
- a housing having a slot passing at least partially therearound;
a plunger movable within the housing, said plunger having an electrically conductive surface associated with a proximal end thereof;
a biasing mechanism configured to proximally urge the plunger into a position where the electrically conductive surface of the plunger contacts another electrically conductive surface; and
a contact member extending through the slot in the side of the housing, the contact member being configured to advance through the slot each time the plunger is moved back and forth within the housing, said electrically conductive surface of the plunger serving to one of activate or deactivate an associated electrical device when the surface is in contact with another electrically conductive surface.

Abstract
A mechanical limiter device, having: a housing with a slot passing at least partially therearound, the slot forming a plurality of teeth in a side of the housing; a plunger movable within the housing; a biasing mechanism configured to urge the plunger in a proximal direction within the housing; a contact member extending through the slot in the side of the housing, the contact member being configured to advance past at least one of each of the plurality of teeth in the slot each time the plunger is moved back and forth within the housing. The contact member may perform a switching function.

9. A mechanical limiter mechanism for use with an electrical device comprising:
-
a first semi-cylindrical housing portion; a second semi-cylindrical housing portion coupled to the first housing portion so that a slot is formed longitudinally between the first and second housing portions; a biasing member positioned between the first and second housing portions; and a contact member extending through the slot in the housing and operatively coupled to the biasing member, wherein the biasing member is movable by a user to move the contact member within the slot to both establish an electrical connection and stop an electrical connection depending upon the location of the contact member within the slot.

10. A mechanical limiter mechanism for use in activating and deactivating an electrical device comprising:
-
a hollow housing having a wall with a slot extending through the wall; a plunger movable within the housing; a biasing mechanism coupled to the plunger to urge the plunger in a proximal direction; a contact member associated with the biasing mechanism and extending through the slot, the contact member being movable within the slot when the plunger is moved within the housing, said contact member being operable to activate or deactivate an associated electrical device depending upon the position of the contact member within the slot.
