Claim:
A collapsible hunting blind, comprising: a bottomless blind awning comprising two sidewalls, a front wall, a rear wall, and a top wall without any bottom wall, wherein a hiding area is defined within said sidewalls, said front wall, and said rear wall for a hunter hiding within said hiding area; and a collapsible frame, which is adapted to fold between a folded position and a setup position, comprising: two tensional loops provided at said sidewalls respectively for providing a tensional force thereat at said setup position to stretch out said sidewalls in a tensional manner, wherein when each of said tensional loops is twist-folded to reduce said tensional force at said respective sidewall of said blind awning, said sidewalls in an overlapped manner are adapted to twist-fold into a compact structure at said folded position, wherein each of said tensional loops comprises a resilient wire which is coupled end-to-end to form a loop structure and is securely attached to a peripheral edge of said respective sidewall, such that said resilient wire normally stretches out said sidewall in a tensional manner at said setup position while said resilient wire is adapted to twist-fold said sidewall into a plurality of planar sections being overlain one another at said folded position, and wherein each of said front and rear walls has a trapezoid shape such that when said front and rear walls are unfolded at said setup position, said hiding area increases in height and decreases in width from bottom to top; and a retention frame detachably coupling between said sidewalls to retain a distance therebetween at said setup position, wherein said retention frame comprises at least two elongated retention arms each having an affixing end coupling with an upper portion of one of said sidewalls and an opposed detachable end detachably coupling with said another sidewall, wherein when said detachable ends of said retention arms are connected to said respective sidewall, said retention frame is retained between said sidewalls to support said collapsible frame and said blind awning in said setup position, wherein when said detachable ends of said retention arms are detached from said respective sidewall, said retention frame is released between said sidewalls and said sidewalls are adapted to overlap with each other at said folded position.
