Specification of Letters Patent. Patented Feb. 21, 1922.

', Anplleatlon filed llovember 0, 1919. Serial Re. 886,114.

To all :whom it may concern:

Be it known that I, Bmrrna B. MYnRs, a citizen of the United States residing at Los Angeles, in the county of s Angeles and State of California, have invented new and useful Improvements in Foldable Sunshade Frames, of which the following is a specification.

This invention relates to a foldable frame and particularly pertains to a support for a sunshade of the type set forth in United States Letters Patent No. 1,297,225 issued to me March 11, 1919.

It is the ob'ect of this invention to provide a frame or su porting a flexible covering of fabric or t e like whereby a substantially rectangular canopy may be formed, which is especially applicable or use as a sunshade and shelter for bathers.

Another object is to provide a frame of the above character which is foldable so that it may be collapsed into a compact space and rendered convenient for storage and trans ortation.

A rther object is to provide a foldable frame which is so designed that it may be made of few light parts so assembled as to afford a strong and substantial structure and adapted to be securely locked in its open position a ain'=+ accidental collapse.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the frame as seen in its open position and adapted to receive the canopy as indicated in dotted lines.

Figure 2 is a perspective view of the frame showing it in a partly folded position.

Figure 3 is a view in end elevation of the frame in its folded position.

In carryin out my invention, I form a frame embo ying a horizontal top bar 4 fitted at its ends with foldable side standards 5 and 6 pivoted adjacent to the ends of the top bar. In formmg the connection between the top bar and the standards, the ends of the top bar are turned downwardly, as indicated at 'Z, to which the standards are secured by pivot pins 8. A flange 9 is formed on each portion 7 to form an abutment for limiting the outward pivotal movement of the standard; this flange extendin alon side the outer edge of the standar axial y of the pivotal mountin'g thereof.

Each standard is formed of a plurality of

sections

10 and 11 which are connected together by a ivot pin 12, so that the sections may be fol ed together and swung on the pivot 8 to extend substantially parallel with the bar 4.

As a means for. substantially locking the

sections

10 and 11 in alinement with each other the lower section 11 has an elongated and sii htly tapered end portion 13 adapted to over ap the up r section 10 and to receive a sleeve 14 s idable on the section 10 and adapted to encircle both the section 10 and the extended portion 13 of section 11 to retain the sections in alinement and securely hold them against pivotal movement relative to each other in their open position.

The lower ends of the standards are preferably pointed to permit their being readily forced into the ground. The elements just described constitute the main portion of the foldable frame and when unfolded and placed in position, constitute a single to bar sup orted at each end on a single stan ard an forming a substantially rectangular structure. An important feature of this invention resides in means whereby this single support may be ada ted to carry and form a frame for a box 1' e canopy. This means is here shown as residing in a air of

foldable end arms

15 and 16 pivotal y mounted relative to the top bar 4. adjacent to the down turned end portions 7; these arms being connected by pivots 17 to a transverse supporting plate 18 fastened to the top bar so as to adapt the arms to swing in a virtually horizontal plane, and the plate 18 having upturned end flanges 19 arranged to project in the path of travel of the outward movement of the

arms

15 and 16, and to position the latter in alinement with each other, and extending at right angles to the top bar.

spring plate 20 secured to the upper face of the top bar and having a limited yieldable upward movement relative thereto has down turned side flanges 21 adapted to project alongside the

arms

15 and 16 opposite to flanges 19, so as to cooperate with the latter in holding the arms against movement in their open position; the s ring plate being adapted to be bent upwardly to permit the

arms

15 and 16 to be swung inwardly into their folded position alongside of the vtop bar 4: where their outer edges will be en and engaged by aged by the down turned flanges 21, wherey the arms will be securely held in their folded position, as shown in Figure 2.

The outer ends of the

arms

15 and 16 are fitted with buttons 22 or other suitable fastenin s for engagement with eyelets 23 or the li e indicated in dotted lines of a box like canopy 24. This canopy is formed with a rectangular top wall, indicated at 25, adapted to be supported on the frame formed by the top bar 4 and the

arms

15 and 16, and has a back wall portion, indicated at 26, substantially conforming in size and outline to the space encircled by the rectangular frame. The canopy is also formed with side portions 27 adapted to depend from the

arms

15 and 16 and to extend downwardly into engagement with foldable cross arms 28 pivoted at 29 near the lower ends of the standard sections 11, which cross arms have buttons 30 or other suitable fastenings for engagement with the lower ends of the canopy side portions.

In folding the frame, the cross arms 28 are turned to extend parallel with the sections 11, whereupon the sections 11, on loosening the sleeve 14, are folded to extend alongside the sections 10, which are then swung inwardly on their pivots 18 to extend substantially parallel with the to bar 4. The

arms

15 and 16 are then swung inwardly the spring plate 20, as before described, thus folding the frame into a compact space forming a small package convenient for transportation.
