Patent number: 5088245Abstract: An arrangement for interconnecting and supporting a pair of hexagonal building structures includes a pair of common support columns each having a hexagonal shaped connector tube mounted to an upper end thereof. Each connector tube includes apertures in each of the six lateral walls thereof which are adapted for receiving a nut and bolt combination for coupling the tube to the eave beams and roof trusses of two hexagonal building structures. The nut and bolt combinations are hidden from view within the connector tube and adjacent beams to provide a clean, attractive appearance and are not exposed to the elements. The use of common support columns and a common eave beam for adjacent hexagonal building structures simplifies assembly, reduces the number of structural components and building cost, and integrates two or more of such building structure for increased structural strength.Type: GrantFiled: August 7, 1990Date of Patent: February 18, 1992Assignee: W.

Patent number: 4091484Abstract: A storage compartment for a collapsible boat canopy which folds to a horizontal position within the rear portion of the cockpit when not in use. The storage compartment is formed underneath the rear deck of the boat and has a forwardly facing opening closed by means of the rear passenger seat backrest, which is hingedly connected to the leading edge of the rear deck. The structural members for the canopy are supported within tracks on the cockpit side walls thereby permitting the entire canopy structure to be slid rearwardly so that the folded fabric portion is received within the storage compartment. The rear seat backrest is then swung downwardly over the opening and all but the vertical legs of the canopy structure is concealed. An upstanding ridge molded into the floor of the storage compartment serves to prevent the canopy from sliding forwardly.Type: GrantFiled: June 30, 1977Date of Patent: May 30, 1978Assignee: Porter, Inc.Inventor: John R.
