Abstract: A lean-to construction is provided in which a horizontal beam is supported between a supporting structure and a vertical beam spaced from the supporting structure. The vertical and horizontal beams have interengaged end portions and a mortis and tenon joint is provided with a tongue having a configuration to vector the forces resulting from the weight of the horizontal beam into vertical and horizontal forces which urge the vertical beam to tilt towards the horizontal beam and supporting structure, thereby to make the structure more reliable.

Abstract: A structural arrangement is provided which is particularly useful in connection with solar greenhouses. The structural member is suitable for use in a parallel arrangement of the same particularly for the purpose of providing controlled shading. The structural member is provided as a hollow bar of elongated form provided with at least one longitudinally extending track channel having a relatively narrow longitudinally extended slot-mouth. The bar may be provided with two such channels and these channels are substantially circular in cross-section with the mouths defining reentrant angles therewith. In a solar greenhouse, members of the above type support a glazing with a curved-eave section, the bars being curved to shape and the channels therein accommodating the bulbous lateral edges of shades which are retained therein. The shades are transferred from one roller in the direction of a second roller.

Abstract: A prefabricated post and beam lean-to or free standing structure, incorporating a self-aligning, load bearing mortise and tenon joint assembly which results in a mitred joint with no visible hardware when fabricated. The structure is formed from a plurality of post and beams arranged in spaced, parallel, vertical and inclined. Attitudes extending from a lower support surface at the base of the post, with the inclined beams attaching at a higher support surface. The prefabricated sloping mortise in the post allows the beam's prefabricated tenons to be modified, on site, to descend further into the sloping mortise channel enabling the slope to be adjusted. This frame system then supports single or double glass or other sheets of material for lateral support over the enclosure.

Abstract: In a solarium construction, glazing is supported on glazing bars to which the glazing is clamped by means of gasket strips. The glazing bars and strips, which are interconnected are divided into complementary mirror image parts. The force which is used to connect the glazing bar parts together causes the strip parts to be forced together and this displaces the strip parts more tightly against the glazing. This enables a force which is applied within the solarium to be effective externally to fasten the glazing in position.

Abstract: A structural arrangement which is particularly useful in connection with solar greenhouses is provided. Therein is provided a structural member in the form of a hollow bar of elongated form provided with longitudinally extending and parallel track channels having relatively narrow longitudinally extended slot mouths. A shade with a bulbous periphery is engaged in each of the track channels and a guide member is provided which changes the direction of movement of the shade as it exits from the ends of the corresponding track channels. The guide includes tubular extensions which extend into the track channels. The guide furthermore includes arcuate guide channels which are funnel shaped and operate in extension of the tubular extensions. A member operates in conjunction with the tubular extensions to a wall of the afore-mentioned bars for the mounting of the guide.

Abstract: A greenhouse construction is provided which includes adjacent panels, each including a front wall section, a sloped roof section and a curved section which is located between and connects the front wall and sloped roof sections to form a continuous module. Each panel includes and is laterally bordered by glazing bar sections and glazing is provided which extends between these sections. The glazing is, at least in part, supported by the glazing bar sections and includes a curved glazing section corresponding to and constituting at least a part of the curved section of the associated panel. One of the galzing bar sections of each panel abuts the corresponding glazing bar section of the next adjacent panel and is in mirror image and matched relationship therewith. Together the glazing bar sections cooperatively form a glazing bar. The abutting glazing bar sections include matched curved sections which can be matched by being bent simultaneously by a common bending force.

Abstract: A method is provided for constructing a greenhouse or solarium structure with glazing and with provision for ventilation. This method includes supporting a blower in an enclosure having an opening for the venting of the greenhouse or solarium structure and supporting a channel on the enclosure. Inter-engaged with the channel is at least a portion of the glazing of the greenhouse or solarium structure and this is done such that the glazing and enclosure form a part of the structure such that air within the structure can be evacuated by the blower through the opening.

Abstract: A greenhouse construction is provided for support against a supporting structure such as a house. The greenhouse construction comprises a glazing structure consisting of glazing and glazing bars. There is also provided a ridge which supports the glazing structure against, but spaces the same from the supporting structure. The ridge includes openings respectively opening into an enclosure defined by the glazing structure and into ambient atmosphere and there is also provided a blower which exhausts air from the enclosure and expels it into ambient atmosphere via one of the aforesaid openings. The ridge is provided in the form of a plurality of channels, one of which has a face adapted for abutting against the supporting structure and defining a pocket for receiving the glazing bars. Another of the channels is supported on the channel with the aforesaid pocket and this additional channel is provided with its own pocket for supporting a flashing structure.

Abstract: In one form a greenhouse or solarium is provided in which the glazing is spaced from its supporting structure by channels employed along the end edges and top edge of the greenhouse or solarium structure. The spacing is effected by the use of channels which extend entirely along the end edges to obturate the space between the end edges and the supporting structure. Additional channels are provided in parallel with each other at spaced positions along the top edge of the glazing in order to connect the same to the supporting structure and space the top edge from the supporting structure. This develops an opening adjacent the top edge of the glazing which is covered by a shed mounted on the supporting structure. Suitably positioned fans are used to exhaust air from the enclosure formed by the glazing and a flap closing is provided for the opening adjacent the top edge in order to selectively obturate the same. A roll down cover is provided whereby selective covering of the glazing is enabled.
