Abstract
A plant protection device having a ventilation opening shield that may be protectedly positioned between a housing and a mounting socket. A temperature sensitive actuator may be provided in the socket and the shield may pivotally move about the socket between a position impeding airflow through the ventilation opening and a position facilitating airflow through the ventilation opening. Various embodiments and features are disclosed including a reinforced housing, multi-part housing construction, and a shield mounting structure provided through the shield, among other features.
Claims20
A plant protection device, comprising:
- a housing having a plurality of ventilation openings located towards a top thereof;
- a shield located within the housing;
- and
- an actuator coupled to the housing and the shield;
- wherein the shield is moveable by the actuator between a first position in which the shield substantially impedes air flow through the ventilation openings and a second position in which the shield does not substantially impede air flow through the ventilation openings.
A plant protection device, comprising:
- a housing having a plurality of ventilation openings;
- a shield moveably coupled to the housing for movement between a first position in which the shield substantially impedes air flow through the ventilation openings and a second position in which the shield does not substantially impede air flow through the ventilation openings;
- and
- a socket that supports the shield;
- wherein the housing protects the shield at least in part against interference from above and the socket protects the shield at least in part against interference from below.
A plant protection device, comprising:
- a housing having a primary ventilation opening;
- a temperature sensitive actuator;
- a shield moveable between a position blocking the ventilation opening and a position not blocking the ventilation opening;
- and
- a socket that supports the actuator and shield;
- wherein the socket is coupled through the shield to the housing.
