Abstract
An indicator rod responsive to environmental variations is disclosed. A handle defines an elongated cavity having a linear axis. A pin is received within the cavity substantially along the linear axis, and is adapted to rotate about the linear axis. An indicator member is secured to the pin such that the pin extends in a substantially non-parallel orientation from the indicator member.
Claims13
An indicator rod responsive to environmental variations, said indicator rod comprising:
- an indicator member having a first end and a second end;
- a pin secured proximate said indicator member first end such that said pin extends in a substantially non-parallel orientation from said indicator member;
- and
- a handle defining an elongated cavity having a linear axis, said handle being adapted to receive said pin within said cavity substantially along said linear axis such as to allow said pin to rotate about said linear axis within said cavity;
- whereby said indicator member and said pin are capable of rotating proximate said handle in response to environmental variations acting upon said indicator rod and wherein said indicator member is defined by a selectively collapsible member.

An indicator rod responsive to environmental variations, said indicator rod comprising:
- an indicator member having a first end and a second end;
- a pin secured proximate said indicator member first end such that said pin extends in a substantially non-parallel orientation from said indicator member;
- a handle defining an elongated cavity having a linear axis, said handle being adapted to receive said pin within said cavity substantially along said linear axis such as to allow said pin to rotate about said linear axis within said cavity;
- and
- at least one fastener configured to secure said pin within said cavity;
- whereby said indicator member and said pin are capable of rotating proximate said handle in response to environmental variations acting upon said indicator rod.

An indicator rod responsive to environmental variations, said indicator rod comprising:
- an indicator member having a first end and a second end;
- a pin secured proximate said indicator member first end such that said pin extends in a substantially non-parallel orientation from said indicator member;
- a handle defining an elongated cavity having a linear axis, said handle being adapted to receive said pin within said cavity substantially along said linear axis such as to allow said pin to rotate about said linear axis within said cavity;
- a reactive material adapted to be responsive to at least one environmental variation, said reactive material being secured to said indicator member proximate said second end;
- whereby said indicator member and said pin are capable of rotating proximate said handle in response to environmental variations acting upon said indicator rod and wherein said reactive material is of sufficient mass to substantially increase downward gravitational forces acting upon said indicator member as a result of gravity acting upon said reactive material.
