Abstract

Abstract An umbrella tent construction includes a plurality of elongated resilient ribs each pivoted at one end to the flange portion of a top base member which includes a vertical post portion projecting downward from the flange. A brace is pivoted at one end to each rib intermediate the ends of the latter, and the opposite end of the braces are pivoted to a hub disposed vertically below the base member. The hub is movable vertically toward and away from the base member across a plane extending through the axes of the pivot connections of the braces to the ribs, to effect opening and closing of the ribs. Abutment means operatively interengages the base member and hub in a predetermined position of the latter above said plane, to limit the upward movement of the hub toward the base member and thus establish the open condition of the ribs. A flexible tent cover is secured to the ribs and is stretched tight as the ribs move toward said open position. The stretched cover resiliently resists vertical movement of the hub upward across said plane, whereby the hub snaps upwardly across said plane to said open position of the ribs in which the abutment means ingerengages the base and hub. The stretched cover thus locks the hub in said upward position and thereby secures the ribs in said open condition. By pulling the hub downward across said plane, against the resistance of the stretched cover, the hub and braces are unlocked, whereupon the braces and ribs are collapsed to tent-folding condition.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 197 words
An umbrella tent comprising a. a framework including 1. an imperforate top base member including a flange portion and a vertical post portion extending downward from the flange portion, 2. a plurality of elongated resilient ribs pivoted at their upper ends to the flange portion of the top base member at peripherally spaced positions for movement between extended and retracted positions, 3. a plurality of braces connected pivotally at their outer ends one to each of the ribs intermediate the ends of the latter, 4. a hub pivotally interconnecting the inner ends of the braces and positioned vertically below the top base member for vertical movement toward and away from the latter across the plane extending through the pivot connections of the braces to the ribs, to move the ribs between said extended and retracted positions, and 5. abutment means on the top base member and hub interengageable when the hub moves upward across said plane to limit said upward movement, and b. flexible cover material supported by the framework and dimensioned to become stretched as the ribs move toward extended position, whereby to maintain the abutment means resiliently in interengagement and the tent in erected condition.
Claim 2
Dependent Claim 197 words
An umbrella tent comprising a. a framework including 1. an imperforate top base member including a flange portion and a vertical post portion extending downward from the flange portion, 2. a plurality of elongated resilient ribs pivoted at their upper ends to the flange portion of the top base member at peripherally spaced positions for movement between extended and retracted positions, 3. a plurality of braces connected pivotally at their outer ends one to each of the ribs intermediate the ends of the latter, 4. a hub pivotally interconnecting the inner ends of the braces and positioned vertically below the top base member for vertical movement toward and away from the latter across the plane extending through the pivot connections of the braces to the ribs, to move the ribs between said extended and retracted positions, and 5. abutment means on the top base member and hub interengageable when the hub moves upward across said plane to limit said upward movement, and b. flexible cover material supported by the framework and dimensioned to become stretched as the ribs move toward extended position, whereby to maintain the abutment means resiliently in interengagement and the tent in erected condition.
Claim 3
Dependent Claim 31 words
a plurality of elongated resilient ribs pivoted at their upper ends to the flange portion of the top base member at peripherally spaced positions for movement between extended and retracted positions,
Claim 4
Dependent Claim 31 words
a plurality of elongated resilient ribs pivoted at their upper ends to the flange portion of the top base member at peripherally spaced positions for movement between extended and retracted positions,
Claim 5
Dependent Claim 124 words
The umbrella tent of claim 1 wherein each of the ribs includes a main rib section pivoted to the flange of the top base member and an extension rib section connected pivotally to the outer end of the main rib section for movement through an arc of substantially 180* between an extended position substantially aligned with the main rib section and a retracted position adjacent the outer side of the main rib section, the extension rib sections being dimensioned to extend laterally from the main rib sections in a position intermediate said extended and retracted positions a distance defining the ground dimensions of the erected tent, whereby the tent may be seCured to the ground at an initial stage of erection of the tent.
Claim 6
Dependent Claim 22 words
a plurality of braces connected pivotally at their outer ends one to each of the ribs intermediate the ends of the latter,
Claim 7
Dependent Claim 22 words
a plurality of braces connected pivotally at their outer ends one to each of the ribs intermediate the ends of the latter,
Claim 8
Dependent Claim 29 words
The umbrella tent of claim 1 wherein the top base member includes a clamp member adjustable toward and away from the flange portion for clamping the cover material therebetween.
Claim 9
Dependent Claim 65 words
The umbrella tent of claim 1 wherein the flange portion of the top base member has a threaded opening therethrough and the vertical post portion has an intermediate threaded section engageable removably with said threaded opening, and a clamp member is located on the post adjacent the outer end of the threaded section for clamping said cover material between said clamp member and flange portion.
Claim 10
Dependent Claim 52 words
a hub pivotally interconnecting the inner ends of the braces and positioned vertically below the top base member for vertical movement toward and away from the latter across the plane extending through the pivot connections of the braces to the ribs, to move the ribs between said extended and retracted positions, and
