Abstract

A vented metal umbrella kit comprising a pair of substantially diametrically divided, prefabricated canopy half-sections, each half-section of which is prefabricated of a plurality of elongated sheet metal channel members tapered from end to end and secured in relatively side to side, interstraddling, fan-like relative disposition, a vertical support structure having a support arm adjustably secured at one end and a support disc removably attachable to the outer end of the support arm, means securing the umbrella half-sections in depending relation about the support disc, and a cone member of greater diameter than the support disc removably securable over the support disc and the attached end portions of the canopy half-sections assembled thereto.

Claims

1. An umbrella comprising, in combination, a vertical support structure, a support arm adjustably secured at one end to the upper end of said vertical support structure, an umbrella disc secured to the other end of said support arm, a pair of umbrella canopy half-sections, each substantially in the shape of a half sector of a circle having its apex end truncated along an arc concentric with its origin, means securing said umbrella half-sections in side-by-side depending relation about said support disc with their apex ends secured to said support disc, a cone member of greater diameter than said support disc secured over said support disc and inner end portions of said umbrella canopy half-sections, brace mechanism supporting inside portions of said umbrella canopy half-sections with respect to lower end portions of said support arm, said brace mechanism comprising a plurality of tubular radial arms, a cylindrical collar member provided at the lower end of said support arm, said collar member having in its upper end a plurality of peripherally-arranged arcuate recesses, one for each of said radial arms, each arm having at one end a down-turned end portion seated one each in said arcuate recesses, means securing the other end of each of said radial arms to radial mid-portions of said umbrella half canopy half-sections, said brace mechanism further comprising tubular members fixed against the underside of each said umbrella canopy half-sections in concentric relation thereto, and T-connector fittings secured to said arcuate tubular members and having sockets seating the other ends of said radial arms, and means securing said down-turned end portions of said radial arms to said support arm, said support arms securing means comprising a plurality of screw-threaded openings in said support arm and bolts extending through diametrical openings in said down-turned end portions and received one each in said threaded openings.

2. An umbrella as defined in claim 1 wherein said plurality of screw-threaded openings in said support arm are peripherally spaced and alternately vertically staggered about and along said support arm.

3. An umbrella as defined in claim 2, wherein in each of said umbrella canopy half-sections comprises a plurality of metal channel members tapered from end to end and secured in side-to-side, fan-like relative disposition, said channel members comprising a plurality of top channel members and plurality of bottom channel members, said top and bottom channel members each having a top wall portion, opposed side wall portions, and inwardly-turned portions at the outer ends of said side wall portions, said top and bottom channel members being interspaced and relatively inverted.

4. An umbrella kit comprising, in combination, a vertical support structure, a support arm, means for removably securing one end of said support arm to the upper end of said support structure, an umbrella support disc removably securable to the other end of said support arm, a plurality of umbrella canopy half-sections, each substantially in the shape of a half sector of a circle having its apex end truncated along an arc concentric with its origin, means for removably securing said umbrella canopy half sections in side-by-side, spaced, depending relation about said support disc and to said support disc at their apex ends, a cone member of greater diameter than said support disc removably securable over said support disc, a plurality of brace members removably securable between inside portions of said umbrella canopy half-sections and lower end portions of said support arm, said brace mechanism comprising a plurality of tubular radial arms, a cylindrical collar member provided at the lower end of said support arm, said collar member having in its upper end a plurality of peripherally arranged arcuate recesses, one for each of said radial arms, said radial arms, said radial arms each having at one end down-turned portions seatable one each in said arcuate recesses, and means securing the other end of said radial arms to radial mid-portions of said umbrella canopy half-sections, said brace mechanism further comprising tubular members fixed against the underside of each of said umbrella canopy half-sections in concentric relation thereto, and T-connector fittings secured to said arcuate tubular members and having sockets seating the other ends of said radial arms and further including means securing said down-turned end portions of said radial arms to said support arm, said support arms securing means comprising a plurality of screw-threaded openings in said support arm and bolts extending through diametrical openings in said down-turned end portions and received one each in said threaded openings.

5. An umbrella kit as defined in claim 4 wherein said plurality of screw-threaded openings in said support arm are peripherally spaced and alternately vertically staggered about and along said support arm.

6. An umbrella kit as defined in claim 5, wherein in each of said umbrella canopy half-sections comprises a plurality of metal channel members tapered from end to end and secured in side-to-side, fan-like relative disposition, said channel members comprising a plurality of top channel members and plurality of bottom channel members, said top and bottom channel members each having a top wall portion, opposed side wall portions, and inwardly-turned portions at the outer ends of said side wall portions, said top and bottom channel members being interspaced and relatively inverted.
