A sun tracking canopy structure having a canopy positionable to maintain a shaded area based on calculated solar elevation and azimuth.

Portable hunting blind including seat/chair for use in hunting or similar environment including side panels and hinge brackets having support arms mounted to side panels; seat mounted to side panels, the seat together with side panels and hinge brackets having support arms form a chair-like structure; skirt put around side panels to conceal hunter sitting on seat; and bonnets and blind top. Blind top conceals hunter while allowing hunter to see what is going on around him. To hunt or to come out of portable hunting blind, hunter stands up throwing back bonnets and hitting the skirt with his knee, thereby detaching skirt. Portable hunting blind is folded by folding side panels along with skirt with help of hinge brackets and by throwing back bonnets to retracted state for easy transport.

A coupling device suitable for interconnecting two beam ends is provided, wherein the beam with the beam end has an elongate axis, where on a first beam end is arranged first interconnection units having two first parallel flange elements arranged with a mutual first distance x, wherein in each flange is designed a cut-out with a cross-section in the plane of the flange; a second beam end is arranged a second interconnection unit having a second flange, the width of the second flange across the plane of the second flange is smaller than or equal to x, and where largely perpendicular to the plane of the second flange, a connecting element protrudes on each side of the second flange, the cross-section of the connecting element in the plane of the second flange allows insertion of the connecting element into the cut-outs of the first flanges on the first beam end.

Disclosed is a tent frame, a unit tent and an extendable cubic tent group. The tent group is assembled from a plurality of unit tents sharing edge structures. The unit tent consists of an inflatable tarpaulin and a tent frame. The tent frame includes bases, columns and beams. The beam is provided with at least a first water channel and a second water channel in a length direction. The present invention is simplified in the structures of the columns and the beams, which is more beneficial to coping with the situation of large water volume. Besides, the assembly of small parts can be reduced, and the stability of the structure can be enhanced, so that the structural weight of the overall frame is greatly reduced while the hidden water discharge function is reserved.

A portable multi-hinged shelter for housing one or more individuals and storing gear commonly associated with outdoor excursions and like activities, which includes a box frame mounted atop of and connected to an open cargo bay of a vehicle and fitted with a secondary shelter shell and a supportive wind wall removably attached to the box frame and pivotally connected to a lower wind wall and sideward arms of a moveable frame assembly. The moveable frame assembly further includes primary and secondary canopies pivotally connected to the sideward arms and a ground brace pivotally connected to the primary canopy that collectively accept and support attachment of a primary shelter shell, whereby manual manipulation and adjustment of angular moveable supports or alternative telescopic supports that interact with select structural aspects of the supportive wind wall and moveable frame assembly yields expansion and contraction of the moveable frame assembly respectively for occupancy and compact transport alongside the vehicle.

The present invention relates to a retractable umbrella that can be attached above a door that opens to allow people to exit or enter an enclosure, such as, a bus, airplane, train, house, building, and the like. The retractable umbrella comprises several frames to which umbrella sheets are attached and that nest within one another within a housing that is attached to said enclosure. With a switch or button, a motor linearly displaces a shaft that displaces each of said frames out of the housing so as to provide protection for people from the rain as they exit or enter said enclosure.
