Abstract
Abstract A tent comprising a frame, sheet material on the frame formed into an enclosure having a base and a ceiling with an opening in the ceiling and an elongated pivot member having opposite ends and mounted for pivotal movement over the opening. A flexible flap is coupled to the sheet material and to the pivot member so that the pivot member can pivot to cause the flap to open and at least partially close the opening. A rain fly of flexible sheet material is adapted to overlie the opening and be supported by the pivot member above the opening to thereby close the opening and increase the vertical space available in the tent.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
152 words
A tent comprising; a frame including crossed frame members; sheet material supported by the frame and formed into an enclosure having a peripheral wall and an elongated sloped ceiling with an opening in the ceiling, said opening extending longitudinally for substantially less than the full longitudinal length of the ceiling; an elongated, bowed pivot member having opposite ends, said pivot member extending over the ceiling generally in the direction of elongation of the ceiling; means for mounting the pivot member for pivotal movement over the opening; a flexible flap for opening and at least partially closing the opening, a first region of said flap being coupled to the sheet material; and means for attaching a second region of the flap to the pivot member whereby the pivot member can pivot to move the flap transversely to the direction of elongation of the ceiling to open and at least partially close the opening.
Claim 2
Dependent Claim
152 words
A tent comprising; a frame including crossed frame members; sheet material supported by the frame and formed into an enclosure having a peripheral wall and an elongated sloped ceiling with an opening in the ceiling, said opening extending longitudinally for substantially less than the full longitudinal length of the ceiling; an elongated, bowed pivot member having opposite ends, said pivot member extending over the ceiling generally in the direction of elongation of the ceiling; means for mounting the pivot member for pivotal movement over the opening; a flexible flap for opening and at least partially closing the opening, a first region of said flap being coupled to the sheet material; and means for attaching a second region of the flap to the pivot member whereby the pivot member can pivot to move the flap transversely to the direction of elongation of the ceiling to open and at least partially close the opening.
Claim 3
Dependent Claim
31 words
A tent as defined in claim 1 including an elongated flexible tensioning means coupled to the flap for restraining the second region of the flap from moving along the pivot member.
Claim 4
Dependent Claim
35 words
A tent as defined in claim 1 including first and second elongated flexible tensioning members coupled to said second region of the flap and to the flexible sheet material on opposite sides of the opening.
Claim 5
Dependent Claim
25 words
A tent as defined in claim 1 wherein said pivot member is resilient and is deflected by the mounting means to bow the pivot member.
Claim 6
Dependent Claim
34 words
A tent as defined in claim 1 wherein the mounting means includes a pocket for receiving one of the ends of the pivot member and the pocket is pivotally attached to the sheet material.
Claim 7
Dependent Claim
55 words
A tent as defined in claim 1 wherein the mounting means includes first and second pockets separated by said opening, said pockets releasably receive said ends, respectively, of the pivot member and are pivotally attached to the sheet material and the pivot member is resilient and is deflected into a bowed configuration by the pockets.
Claim 8
Dependent Claim
27 words
A tent as defined in claim 1 wherein said sheet material includes a transparent section in the peripheral wall extending substantially around the tent adjacent the ceiling.
Claim 9
Dependent Claim
47 words
A tent as defined in claim 1 including a rain fly of flexible sheet material adapted to overlie said opening and be supported by the pivot member above the opening to thereby close the opening and increase the headroom in the tent above the crossed frame members.
Claim 10
Dependent Claim
18 words
A tent as defined in claim 8 including means releasably attaching the rain fly to the pivot member.
Claim 11
Dependent Claim
50 words
A tent as defined in claim 6 including first and second elongated flexible tensioning members coupled to said second region of the flap and to the flexible sheet material on opposite sides of the opening, said sheet material includes a transparent section extending substantially around the tent adjacent the ceiling.
Claim 12
Dependent Claim
45 words
A tent as defined in claim 1 wherein the mounting means includes first and second pockets separated by said opening, said pockets receive said ends, respectively, of the pivot member and are pivotally attached to the sheet material adjacent the opposite ends of the ceiling.
Claim 13
Dependent Claim
125 words
A tent comprising: a frame including crossed frame members; sheet material supported by the frame and formed into an enclosure having a peripheral wall and an elongated sloped ceiling with an opening in the ceiling, said opening extending longitudinally for substantially less than the full longitudinal length of the ceiling; an elongated pivot member having opposite ends, said pivot member extending over the ceiling generally in the direction of elongation of the ceiling; means for mounting the pivot member for pivotal movement over the opening; and a rain fly of flexible sheet material adapted to overlie said opening and be supported by the pivot member above gthe opening to thereby close the opening and increase the headroom in the tent above the crossed frame members.
Claim 14
Dependent Claim
