This invention relates to collapsible tents, umbrellas,

ribs 20. There are two curled end portions on each of
the grommets 19 arranged one above the other. In this
instance there are six resilient metal ribs 20 and these
radiate from the supporting unit 14. When the tent is in
its position of use, the ribs 20 not only radiate from the
unit 14 but how outwardly and downwardly to place the
walls under tension so that the body of the tent is main
tained taut.
On the upper plate 16 of the unit 14 there is a pair

position of use, a ?exible strap 25 is connected to the
lower end of the tent near the ?aps 11 and a suitable fas
tener 26 enables the strap to be detachably connected to
the other end of the tent body. In this manner the tent
is held under tension and presents a neat and attractive

By loosening the zipper fastener 34, the umbrella body
can be collapsed similar vto the collapsing of the tent body
above described. Also the disposing of the body in posi
tion of use is accomplished merely by drawing the free
ends of the body toward each other, connecting the zip
per fastener and engaging the hook 35 with the loop 36.
Numerous changes in details of construction, arrange
ment and operation may be effected without departing 10
from the spirit of the invention, especially as de?ned in
the appended claim.
What I claim is:
A collapsible tent, umbrella or the like comprising a
?exible fabric body of dome-like form, and a supporting 15
structure for same, said structure having a relatively flat
mounting unit in the top of the body disposed in gen
erally horizontal position when in position of use, a plu~
rality of posts on said mounting unit and disposed in ver
tically disposed planes when the body is in position of 20
use, a plurality of spring metal ribs having one end at
against their respective stops, thus spreading apart the free
end portions of the ribs, and means for retaining the body
in position of use.
