Abstract
An insulated cold frame includes an insulated box having an upwardly extending insulated rear wall and a rigid insulated cover rotatable about a horizontal axis from a sealed position to a fully open position. A glazing cover inside the insulated cover permits light to reach the interior of the cold frame and provides a heat gain during daylight hours when the insulated cover is open. The glazing cover is rotatable about substantially a common axis with the insulated cover to provide ventilation and temperature control.
Claims20
An insulated chamber comprising
- (a) an insulated box having an upper periphery,
- (b) a fixed, insulated upstanding rear wall on said box, said rear wall extending above the upper periphery of the box, and
- (c) an insulated cover moveable between
- (i) a closed position in which said insulated cover forms a seal with said upstanding rear wall and with said box to form a closed, insulated chamber, and
- (ii) an open position in which said upstanding rear wall is exposed to ambient light to reflect light into said box.
An insulated chamber comprising
- (a) an insulated box having an open top,
- (b) a rigid, insulated cover moveable between a closed position in which said insulated cover closes said open top to form a closed, insulated chamber, and an open position, and
- (c) a light-transmitting glazing cover within said insulated cover, said light-transmitting glazing cover being moveable, when said insulated cover is in said open position, between a closed position in which said glazing cover closes said open top and an open position in which the interior of said box is exposed to ambient atmosphere.
An insulated chamber, having an insulated cover moveable between a closed position and an open position and a glazing cover within said insulated cover, said glazing cover being moveable between a closed position and an open position, said chamber having a front face including said insulated cover and said glazing cover, and a pod of sufficient size to accommodate a human, said pod being mateable with said front face of said insulated chamber to close said chamber when said insulated cover and said glazing cover are in said open positions, said insulated cover and said glazing cover being reachable from said pod for opening and closing said insulated cover and said glazing cover from said pod, said pod being moveable away from said chamber front face to expose said insulated cover.
