COVERED FRAME SHELTER AND METHOD OF ERECTION

摘要

A generally rectangular shelter with a readily assembled frame mounted on a base and covered with a flexible sheet material secured to the frame and base is provided. The base is normally of wood and is placed on the ground or other planar surface Spaced at a desirable distance along each side of the base are pivotal and adjustable supports fixed to the base. To the supports are connected a series of assembled frame ribs transverse to the length of shelter. The frame ribs are normally assembled in an arcuate shape from several pieces of tubing coupled together by a special coupler. The tubes are adapted to receive other tubes by having pin receiving tabs welded to them in appropriate places. Purlins or other spacers are connected between the frame ribs so that all the frame ribs may be drawn up from an assembled horizontal position to an upright position as a unit. Cross bracing is placed between the frame ribs as required and a cover formed of several panels of flexible sheet material is then placed over the erected frame to form a basic shelter. The several panels are generally insulated fabric and are secured to the frame ribs by having all edges carrying a single continuous draw cord. The panels overlap with the overlapping side edges carrying the draw cord partially wrapping each panel side edge around an adjacent frame rib covered by each panel in a sealing and securing relationship when the panels are tightened by the pivotal and adjustable supports. The ends of the panels include grommets that receive fasteners that are imbedded in the base for total securement of the panels. Front and rear basically semicircular panels are each secured to an end rib and the base in a similar manner and are placed against front and rear end wall posts of front and rear end walls which are assembled before or after pivoting and are connected to the base and an end frame rib. The total cover or the basic shelter cover is tightened by vertically adjusting all the pivotal and adjustable supports fastened to the base each carrying a bottom end of a frame rib.
