A method and apparatus for a temporary corridor, to cover a walkway or the like, comprising easily transportable elements that can be quickly erected and disassembled on a selected site by one person.

BACKGROUND OF THE INVENTION 
     The invention relates to a method and apparatus for a temporary corridor for sheltering individuals against adverse weather conditions comprising easily transportable elements that can be quickly erected and disassembled on a selected site. 
     The temporary corridor should be suitably sized to accommodate individuals and specifically sized to meet the requirements of the Americans With Disabilities Act. It is envisioned that the vertical dimension of the vertical member be approximately six (6) feet from the top section to the bottom section and that the lateral dimension of the horizontal member, measured perpendicular to the side flange, one flange to the other, will be on the order of three and a half (31/2) to four (4) feet. 
     This temporary corridor will be a significant aid to the disabled and elderly during extreme cold, icy and snowy conditions. 
     It is contemplated that the generally horizontal members and vertical members will be made of appropriate sheet metal which may be galvanized to prevent rust, that the elongated seal will be made of a flexible rubberized material, that the interlocking pins and interlocking pegs will be manufactured from flexibly rigid plastic. Alternatively, the generally horizontal members and vertical members could be made of plastic through an injection molding or extrusion process. That windows in the vertical members will be made of plexiglas or other suitable translucent material. The anchors, as disclosed can be made of either plastic or a metallic material. 
     Alternative technology is available in the form of various sheltering devices including U.S. Pat. No. 3,059,734 issued to Tripp on Oct. 23, 1962 reveals a fabricated building structure employing self-retaining form fasteners which pass through a slotted opening in the horizontal web of the channel which will lock in place when turned. The principal disadvantage of such a device is that it is not easily disassembled as is the present invention. 
     A patent to Blaski, U.S. Pat. No. 3,535,836 issued on Oct. 27, 1970, teaches a curved building construction employing roof panels and curved side panels. 
     U.S. Pat. No. 5,279,085 issued to DiPaolo on Jan. 19, 1994 reveals a covering walkway system for a parking lot. This particular patent does not provide for structural elements that are erected and disassembled as is disclosed in the present invention. 
     A temporary shelter is disclosed in U.S. Pat. No. 4,255,912 issued to Kovacs on Mar. 17, 1981. However, the shelter units are fully enclosed for temporary building modules. 
     A vault structure for protection of roadways against snow disclosed in U.S. Pat. No. 4,885,879 issued to Plantier on Dec. 12, 1989 may serve a related function, but the elements are clearly distinguishable requiring concrete foundations supports and a curved skeletal structure over which a covering is provided. Similarly, a pre-fabricated shelter is disclosed in recently issued U.S. Pat. No. 5,295,335 issued to Collier on Mar. 22, 1994, providing a skeletal structure (see particularly FIG. 2) and a covering. The manner in which the elements are combined do not reflect the portable method and structure which is provided for the instant invention. 
     In U.S. Pat. No. 2,828,757 issued to Thaxton, Jr., on Apr. 1, 1958, a collapsible passageway comprising a skeletal structure and side and rooftop members. Said elements and the means for connection are structurally different from the easily erected and disassembled members of the instant invention. 
     Some of the drawbacks to these designs are that each teaches a structure which is not easily erected and disassembled. Moreover, none of the foregoing inventions is designed to be anchored impermanently to the ground. 
     The citation of the foregoing publications is not an admission that any particular publication constitutes prior art, or that any publication alone or in conjunction with others, renders unpatentable any pending claim of the present application. None of the cited publications is believed to detract from the patentability of the claimed invention. 
     ADVANTAGES OF THIS INVENTION 
     Unlike the foregoing devices which teach structures that support permanent and semi-permanent sheltering structures, the instant invention is comprised of easily transportable components that are designed to fit easily together, be fastened quickly, and thus easily erected without a substantial investment of time or the use of tools. 
     The fastening means is primarily a locking pin/peg and an anchor both of which can be installed and removed without tools. The locking pins and pegs, which may be identical, have two legs that are flexible extending from a free end of a shank and a head on the other end. This flexibility allows the free end of the leg of the shank to be inserted into aligned holes of the horizontal member and vertical members respectively to connect one to the other. Moreover, the side flanges which are preferably perpendicular (or alternately, flat and overlapping) to the central rectangular body shape of the vertical member allowing adjacent side sections to be easily joined together by the locking pegs. 
     The anchors provided have stabilizing radially extending arms which interlock with appropriately disposed holes adjacent to the central aperture in the bottom section of the vertical member for stabilizing the anchor once it is positioned. 
     Another advantage is that no reinforcing rods are required. The arched characteristic of the generally horizontal member will provide additional strength and about an additional foot of head clearance. Furthermore, the addition of ribs to either or both of the generally horizontal members and the vertical members will provide further strengthening. 
     The arched horizontal member side flanges will provide additional wind stability. The width of the vertical members that could be produced in one, two, and four foot widths. Vertical members, generally six feet in height, would be produced in four foot widths. The temporary corridor of this important invention may have vertical members with a height greater than six feet, perhaps about six feet six inches, to accommodate irregular site topology with a central sidewalk over which the temporary corridor is erected disposed at a higher elevation than adjacent terrain. 
     In brief, this temporary corridor of the present invention provides erectable components and fasteners that can be easily transported, erected and disassembled, and yet provide substantial shelter for individuals in need of temporary protection. The temporary corridor is designed to be assembled by one person. 
     Still other advantages will be apparent from the disclosure that follows.
