Abstract
A plant protector comprising a housing of sufficient dimensions to enclose a plant and having a ventilation opening therein. A cover is provided for covering the ventilation opening and a thermal controlled actuator is coupled between the cover and housing for moving the cover between a closed position at lower temperatures where the cover is positioned over the opening and an open position at higher temperatures where the cover is not positioned over the opening. The cover may be pivotally mounted on the housing and the actuator is preferably located between the cover and housing adjacent the pivot.
Claims15
A plant protector, comprising:
- a housing of sufficient dimensions to enclose a plant, said housing having a plurality of ventilation openings therein;
- a cover for said ventilation openings;
- and
- a thermal controlled actuator directly operably coupled to both said housing and said cover for moving said cover between a closed position at lower temperatures where said cover is positioned over said openings and an open position at higher temperatures where said cover is not positioned over said openings;
- and
- wherein said plurality of ventilation openings are distributed around said plant protector so as to provide cross ventilation of air through said plant protector.
A plant protector, comprising:
- a housing of sufficient dimensions to enclose a plant, said housing having a ventilation opening therein;
- a cover for said ventilation opening;
- and
- a thermal controlled actuator operably coupled to said housing and said cover for moving said cover between a closed position at lower temperatures where said cover is positioned over said opening and an open position at higher temperatures where said cover is not positioned over said opening;
- wherein the weight of said cover is essentially balanced on said housing on a single pivot point;
- and
- wherein said cover includes a pivot pin and said housing includes a pivot pin receiving shaft, add wherein the point of contact of said pivot pin with the bottom of said receiving shaft is said pivot point.
A plant protector, comprising:
- a housing of sufficient dimensions to enclose a plant, said housing having a ventilation opening therein;
- a cover for said ventilation opening;
- and
- a thermal controlled actuator operably coupled to said housing and said cover for moving said cover between a closed position at lower temperatures where said cover is positioned over said opening and an open position at higher temperatures where said cover is not positioned over said opening;
- wherein said actuator is mounted external to said housing and covered by said cover.
