Abstract
Abstract A portable hunting blind assembly having a collapsible umbrella roof structure supported from a central hollow cylinder and extending outwardly for terminating in a polygonal body having sides defined by the ribs of the roof structure, a handle supporting of the umbrella roof structure telescopically connected to an internal sleeve in the cylinder by means of a pivot arrangement, the handle received at its free end in a stake support structure or member having its distal end securely anchored in the ground, and an array of panel screening material sections depending from each of the polygonal sides of the roof structure and held firmly in the ground by anchor devices. The take member is telescopically collapsible and adjustable by being fixed to a maximum or some intermediary length values, and the entire portable hunting blind assembly can be reduced to its several component parts for insertion into a back carrying case receiving the components, the carrying case having straps for mounting for carrying on one's back.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
236 words
A portable hunting blind assembly comprising a collapsible umbrella roof means having a plurality of ribs extending from a central cylinder to the periphery of the roof means, the distal ends of the ribs defining points for sides of a polygon edge, the central cylinder extending from the roof means centrally within the roof means for a length proximate the free ends of the ribs, an inner sleeve member for sliding within the length of the central cylinder from end-to-end thereof and having a projection extending from the sleeve member external of the central cylinder, a telescopic member connected by pivot means at one end to the projection and having an arm termination at the other end, an outer sleeve member for sliding on the exterior of the central cylinder, the outer sleeve member being provided with braces connected to the respective ribs, means connecting the inner and outer sleeve members for movement in unison lengthwise of the central cylinder, a telescopic stake means having its telescopic sections comparable to the length of the central cylinder and with a recess at one end of the telescopic stake means for receiving the arm termination and with a spike point at the other end, and means forming a circumferential wall of flexible sheet fabric depending from the peripherally defined sides of the polygon of the roof means for enclosing with the roof to define the portable hunting blind.
Claim 2
Dependent Claim
