FOLDING PORTABLE CANOPY FRAME.

Application med December 7, 1925. Serial No. 73,671.

This invention relates to canopy supports,

I and particularly to a portable support for and has for'an object to provide an improved construction of a support for this purpose which will involve a very small number of parts, which may be folded into a small space and which may be easily and quickly set up or collapsed.

lVith the foregoing and other objects 1n view I have devised the construction illustrated in the accompanying drawing forming a part of this specification, similar reference characters being employed throughout the various figures to indicate corresponding elements thereof. In this drawing- Fig. 1 is a perspective view of my mproved frame set up, and showing a portion of the canopy mounted thereon.

Fig. 2 is a diagrammatical view showing the first step in the process of collapsing the frame.

Fig. 3 is a similar view showing the next ste Fig. 4 is a similar view showing the final step of collapsing the frame.

Fig. 5 is a detail of one means of detachably connecting the arched canopy supports.

Fig. 6 is a plan view and longitudinal section through the connections of the sections of the end members.

Fig. 7 is a side and edge elevation of the connection of the sections of the side members of the frame. A

Fig. 8 is a side and end elevation of the connection between the side and end members, and

Figs. 9 and 10 are detail views showing slightly different means for holding the arched supports in adjusting position.

The frame comprises side members made in two sections 10. These sections are preferably rectangular strips of metal and have their adjacent ends 11 bent laterally in the plane of the members and connected by the pivot 12. This lateral bend offsets the pivot somewhat and allows the sections of the side members to be folded into substantially parallel relation. At their free ends the side sections are bent laterally from the plane of. the section and then twisted through an angle of about 90 to provide laterally extending ears 13 in a plane at right angles to the plane of the side sections to which the sections 14 of the end members are pivoted bymeans of pivots 15. The adjacent ends of these end sections are pivoted together as shown at 16, Fig. 6, and one of the sections has an extended end 17 adapted to overlap the other member and provided with a recess, 18 into which a projection 19 struck up from the other member may project. The resilient action of the extended end 17 cooperates with this lug and recess to provide a spring catch holding the sections in alignment when the frame is set up or expanded, but allows folding of these sections about this pivot in the operation of collapsing the frame, without the necessity of loosening any connections.

.The canopy, indicated as a netting 20, is supported by arch supports 21. These supports also comprise two sections, each pivoted at their lower ends to the side.,members 10 as shown at 22. These members are made of fiat flexible resilient metal which tends to lie straight, as indicated in dotted lines Fig. 1, and therefore, they can be folded parallel with the side members 10. The free ends, however, can be brought together in arched relation due to the flexibility of these members, as indicated in full lines Fig. 1, and the free ends are detachably connected together. A convenient and simple form of connecting means comprises a flat tube 23 permanently secured to one of the members 21., as by rivets 24 and it may be attached to the complementary arched section by merely inserting the free end 25 thereof into the other end of this tubular member, as shown in Fig. 5.

The operation of collapsing and expanding the frame is illustrated in Figs. 2, 3 and 4.. Assuming the frame is set up, as indicated in Fig. 1, the canopy is first removed and then the ends of the arched supports 21 are separated, allowing the supports to move to the dotted line position of Fig. 1 under the resilient action of these members. They are then folded about their pivots 22 to positions parallel with side members 10 of the frame, the movement being indicated at Figs.'2 and 3. The end members 14 are then folded inwardly as indicated at Fig. 2, bringing the side members 10 together, as indicated at Fig. 3. All of the members on opposite sides of the central pivots 12 are then folded about these pivots onto the members on the other side of these pivots, as indicated. in Fig. 4. The frame is now completely folded, and as the members are substantially all parallel to each other they are folded. into a very small space. It

tion shown in Fig. 3, the end sections 14:.

are then brought into alignment separating the side sections 10, thearch supports 21 are then turned to their vertical positions and their free ends secured together. These supports may be clamped in the upright position by means of wing nuts on the pivots 22. The frame is now set up ready to receive the canopy.

Instead of the Wing nuts the canopy suports may be held in the upright positions y the devices shown in Figs. 9 and 10. In Fig. 9 a depression 26 is formed in the side member 10 and a projection 27 is pressed from the support 21 so located as to engage the top of the side member to hold the support elevated and to project into the depression 26 when the support is folded on the side member.

In Fig. 10 a notch 28 is formed in the upper outer edge of the side member 10 of substantially the width of the support 21 so that when the support is bent to the arched osition it will move into the notch 28 and be locked inthe upright position by the shoulders at the ends of the notch.

It will be apparent that the construction of the frame is very simple and that it is easily and quickly set up and collapsed, and that it may be folded into a very small space.

Having thus set forth the nature of my invention what I claim is:

1. In a canopy frame, side members, end members comprising sections pivoted to the side members and to each other so that they may be folded on each other and the side members, and flexible resilient canopy suports pivoted to the side members and tendlng to straighten out so as to be folded against said side members and arranged in pairs on the opposite side members, and

2. In a canopy frame, side members comprising sections pivoted together so as to fold in substantially parallel relation, end members comprising sections pivoted to each other and the free ends of the side members so as to be folded on each other and the side members, and flexible canopy supports pivoted to the side members so as to be folded thereon, said supports being opposed to each other in mils and normally straight, and means for etachably securing the free ends of the supports together in arched relation.

3. In a canopy frame, side members comprising sections of rectangular strips of metal with their adjacent ends bent laterally in the plane of the strip and hinged together, the free ends of the side members being bent laterally from the plane of the members and then twisted to lie in a plane at right angles to the plane of the members to form ears, end members comprising sections pivoted together and to said ears, canopy supports pivoted to the side members and comprising flexible resilient members arranged in pairs, and means for detachably securing the supports together in arched relation.

4. In a canopy frame, side members each comprising a pair of' sections pivoted towardly toward each other to bring the side v members together in parallel relation and the sections of the side members being then foldable together, and means for detachably securing the canopy supports together in arched relation.

In testimony whereof I ailix my signature.

SALVATOR J. SAVA.
