Abstract
An apparatus comprised of flexible gores that are serially connected to each other at their lateral adjoining edges. These gores have a hole in their polar region and a drawstring runs through the gores' holes such that, when the drawstring is pulled, the drawstring pulls the gores' polar regions together and a radial three dimensional shape forms.
Claims20
An apparatus comprised of a pre-cut flat flexible sheet that can be transformed to approximate a three dimensional spheroidal cap shape with a cap angle greater than 90 degrees and its approximately flat plane section,
- where the spheroidal cap shape has two poles and one axis,
- such that the spheroidal cap's axis runs approximately parallel to the plane section, and the plane section has a top and bottom, and two left and right sides,
- where the tangents to the two sides run approximately parallel to the spheroidal cap's axis;
- whereby the pre-cut flat flexible sheet is cut to be comprised of:
- a plane section and a plurality of segments that extend predominantly away from the top and bottom of the plane section such that, each of the segment's two sides is cut to approximately be the length of a geodesic between the plane section and the nearest pole of the spheroidal cap that forms;
- and the region where the segments adjoin the plane section are adapted to have a means of bending;
- and at least one of the plane section's two sides are adjoined to a plurality of gores that are serially connected to each other at their lateral adjoining edges;
- and a plurality of the gores and segments have a hole in at least near their segment pole such that the holes of the plurality of segments are adapted to receive at least one drawstring that is sequentially and unidirectionally made to run through a plurality of the holes of the plurality of gores and segments such that, when the drawstring is pulled, the segment poles that have the drawstring running through their holes will be drawn together and cause the immediate planar region where the holes are located to at least approach stacking on top of each other, and cause a spheroidal cap shape to form.

An apparatus comprised of a flexible flat sheet comprised of
- a top row of segments extending predominantly upwards and
- a bottom row of segments extending predominantly downward,
- where each segment has a distal pole and a proximal region relative to the flexible flat sheet, and
- these two rows of segments are not reflectively symmetrically situated opposite each other, but are rather staggered, such that adjacent segments are connected to each other by both having a portion of their proximal region connected to an opposite row's segment's proximal region;
- and
- where a plurality of the segments of the two rows of segments have a hole in at least near their segment pole such that;
- the holes of the plurality of segments are adapted to receive at least one drawstring that is sequentially and unidirectionally made to run through a plurality of holes of the plurality of segments such that,
- when the drawstring is pulled, the segment poles that have the drawstring running through their holes will be drawn together and cause the immediate planar region where the holes are located to at least approach stacking on top of each other, and cause an at least partially radial three dimensional shape to form.
