Description

SPECIFICATION Canopies and seats A portable weather adjustablethree dimensionally curved canopy and suspended chair suspension housing-frame unit is developed from three curved tubular cross sectioned upright members whose upper (top) extremities by being commonly joined caters for upperframe rigidity, then with each frame member's base ends by also being rigidily connected at ground level bytwo horizontal like base tubular cross sectioned curved linkages which are commonly joined to the frame's centre-rear member's base to two like but oppositely positioned outer frame member's base ends and by the large area of aground surface encompassment oftheframe's base provides the entire frame unit with adequate upright support embracing all three ofthe frame's three upright mem bers wh ich are supported in a stable and secure upright position in a combined frame form.

Due to the frame unit's total common sized tubular cross sectioned fabrication the curved section ofthe frame's baseatground level by virtueofthis tubular cross section caters for the frame's base when situated upon a gently sloping or near level area of mown grass or lawn is able to be slid orglided over the lawn surface which then categorizes this frame unit as being portable.

By way ofthis frame unit's designed plan layout and positioning of constituant curved uprightframe mem bers and their upright curvature in profile (vertically) the combination ofwhich allows for any externally attached series of appropriately segmented canopy sheets to acquire a distinctthree dimensionally curved outer surface or peripheryofweather repel lan- cyfollowing attachment whilst at the same time establishing a canopy covered area of weather protection extending between the three upright frame members and as the entire frame unit (combined upright members) establishes a potential three dimensionally curved foundation or base upon the constituantframe member's combined outer periphery allows for any attached appropriately segmented canopy sheets to automatically acquire an imparted three dimensional curvature in (canopy segment) cross section.

By attaching segmented canopy sheets possessive of appropriately designed supporting frame attachment devices or clips-as shown in Fig.s 10, 1 1, 12 & BR< 13 of the accompanying drawing -varied degrees of attached inner canopy envi ronment can be achieved by so attaching segmented canopy sheets in either a directto the supporting frame's outer surface manner of adhesion --the segmented canopy sheet's inner or underside surface binding tightiy and directly to the supporting frame's outer surface- as shown in Fig.s 12 and 13 of the accompanying drawing-or alternatively by attaching segmented canopy sheets in a louvred setting wherein selected segmented canopy sheets are attached to the supporting frame's outer surface but possessive of a distinct and effective 'air-gap' between the segmented canopy sheet's inner or underside surface and the outer surface ofthe supporting frame-as shown in Fig.s 1O & 11 ofthe accompanying drawings.

Required segmented canopy sheet attachmentto the supporting frame's outer surface is easily acheived forthe louvred setting of attachment by so positioning the canopy segment frame attachment clip's spacing wedge (marked 'A' in Fig.s 10,11,12 & BR< 13 of the accompanying drawing) between the segmented canopy sheet's inner or underside surface and the outer surface ofthe supporting frame as shown in Fig.s 10 & 11 of the accompanying drawings- and thus establishing the segmented canopy sheet's attachment to the supporting frame in the louvred setting.Alternatively by so positioning the segmented canopy sheet attachment clip's spacing wedge in a position to allowthe segmented canopy sheet's inner or underside surface to rest directly upon the supporting frame's outer surface-as shown in Fig.s 12 & BR< 13 of the accompanying drawings-a setting of maximum weather repellancy is then established for the attached canopy segment's attachment to the supporting frame and thereby maintaining air circulation within the attached canopy at a minimum.

Within areas of the supporting frame's three upright members-the upper mid vertical sectors- and due to the plan layout ofthe three frame members, established areas of potential-three point attached suspension resides applicable and appropriate to suspending a three point suspended chair- posses sive of required attachment devices-and allowing the suspended chair to be so positioned as to conveniently be situated directly beneath an outer attached canopy or hood and so provide weather protection to the suspended chair user and via appropriate degrees of segmented canopy sheet attachment-extending from a louvred to a weather tight setting - permits varied conditions of air circulation for the seated user and as shown in Fig.s 7, 8 & 9 of the accompanying drawings- complete and total environmental exposure may be effected by the housing frame's suspension of the suspended chair with zero or no segmented canopy sheet attachment to the supporting frame's outer surface and thus allowing to the seated user total access and exposure to sunlight or similarweather conditions oftotal environmental exposure.
