The cover obviously follows and folds between the stays during this movement. The combined stays and support now assume substantially quarter circle shape in edge elevation.
To further collapse the device, the free end of the bar I6 is disengaged from its hook |8 and the several stays, beginning at the left side, are folded upon themselves, as indicated in dotted lines in Figure 6 and its end |2 having the aperture is engaged over the bar I6, until all the stays have been so engaged, at which time the bar |6 is reengaged with its retaining hook I8. The reinforcing straps |5 prevent too sharp a band in the stays 6 during this final folding movement. Thus, it will be seen, that the shelter has now been collapsed into a relatively compact and easily transportable bundle, capable of storage in the luggage compartment of a vehicle or conveniently carried in the hand to the beach or other place of use. To extend the shelter, the stays are first released from the bar I6, at which time they will spring outward to their normal curvature, as in Figure 6. The stays are then swung about their pivots |61 until the outermost stays abut the wall 9. In this position, the cover has been drawn sufficiently taut. Each of the outermost stays 6 are provided with apertures I9 and, when in fully extended position, align with apertures 20 in the plates 'l and 8. Pins, not shown, may then be inserted through these openings to positively maintain the device in its extended position.
The form of the invention illustrated in Figure 7 contemplates the use of the shelter construction of Figures l to 6 as a fully enclosed tent. In this form of the invention, two additional forward stays are provided to form the front opening, with all the other stays connected with and supporting the cover I l. The two forward stays are pivotally supported in the common pivotal support similar to the stays 6. A similar pivotal support 5 is employed for the stays. A closure flap 2| is preferably connected with the free edges of the cover by any suitable means, such as conventional slide fasteners 22 and this ap may be completely removed or detached at one side only as found desirable. `Obviously, this form of the invention may be made in a plurality of sizes, for beach or lawn use or for commercial use as a collapsible enclosed shelter. The device may likewise be supported as a garden table umbrella, in which case, the pivotal support is mounted upon a suitable post or standard carried by the table.
, In the form of the invention illustrated in Figures 8 to 10, a modified form of support for the stays has been provided. The support, illustrated as a whole by the numeral 23, comprises outer and inner concentric circular shaped rods 24 and 25. The free ends of the rods are connected, as by welding, to a common V-shaped rod 26. A brace rod 21 extends from the rod 26 and is welded' to the rods 24 and 25, as shown, thus providing a rigid circular frame or guide. The rod 26 has its free ends turned down to form one leg of a supporting rod 28, corresponding to the bar |6 and a supporting hook 29, corresponding to the hook |8. A plurality of stays 30, of cylindrical rod stock, suitably spring tempered, are bent to form eyes 3| adjacent their upper free ends, adapted to slidably engage the outer circular rod 24, while a tail extension 32 underlies the inner circular rod 25. The terminal ends of the rod 24 are offset inwardly at their points of connection 4 with the rod 26 and serve to provide sockets or recesses into which the eyes 3| of the two outermost stays will engage to maintain the shelter in the extended position. The tail extensions of the outermost stays are provided with loops 33 adapted to snap over the rod 26 to prevent pivotal movement of the stays. The lower ends of the stays 3U are bent upon themselves to form loops or eyes 34 and a step-on device 35. The cover as illustrated in Figure l0 extends downwardly between the step-on device and the lower end of y the stay and is held against displacement by the rivets 36, that serve to hold the device in preformed shape. The loops 34 are similar to and serve the same purpose as the apertures in the terminal ends |2 of the stays 6.
The collapsing of the shelter device of Figure 8 is accomplished by rst releasing the loops 33 and moving the eyes 3| of the outermost stays from their retaining recesses, after which the stays are caused to slide around the rod 24 to be bunched parallel with each other. The stays are then folded upon themselves and have their looped ends 34 engaged over the rod 28, similar in all respects to the rst form of the invention.
It will be understood, that the number of stays employed may be varied in accordance with the size of the shelter, as obviously, an unusually large shelter will require a greater number of stays to maintain its contour. The mode of assembly, collapsing and extension is identical in each case, with the stays first shifted to the parallel position and then folded to be hooked upon the retainer bar or rod. The construction is extremely simple and cheap to manufacture and its simplicity permits of its extension and collapsing by the very simple procedure outlined, requiring no tools or other means of fastenings to maintain the device in either of its two positions, open or closed. The parts are few and of such nature as to require a minimum of attention. While no particular stress has been placed upon the covering I, it will be obvious that such covering will be made in many ways and designs, in segments and of different colors to lend attractiveness to the shelter. The novel form of ground anchoring means for the shelter provides a very secure means of supporting the device against movement in high winds and the lower circumferential edge of the cover may be provided with a relatively large hem calculated to lie upon the ground when the device has been placed in position.
It is to be understood, that the invention is not limited to the precise arrangement shown, but that it includes within its purview, whatever changes fairly come within either the terms of the invention or the scope of the subjoined claims.
Having described my invention, what I claim 1. A collapsible shelter comprising a plurality of bowed stay devices adapted to be swung in a horizontal plane toward and from each other, the lower ends of the stays being apertured a pivotal support for the several stays, a flexible covering attached to the several stays, the several stays, when moved to a point of contact with each other, adapted to be folded upon themselves, and secured in such folded position by a connection at the pivotal support, the said connection adapted to receive and hold the several apertured ends of the stay.
