Application March 31, 195.2, Serial No. 279,517

1 Claim.

l This invention relates to beach chairs and in particular to the foldable type.

In beach chairs, in which the individual reclines, that is, in which the back and seat meet to form a substantially continuous panel of canvas or the like, the chair when folded to a position to support the person in a reclining position employs a single prop or brace member which is pivoted to the canvas frame to engage a leg frame which forms part of the seat. However, in this type of beach chair it has not been feasible to support the canvas holding parts of the frames or adjust them to a horizontal position and an important object of my invention is to provide in a collapsible chair of the nature referred to, an adjustable prop and brace member which maybe adjusted to tilt the back of the chair to various angles and which may be also adjusted to permit the canvas frame to assume a horizontal position so that the chair may be used as a cot.

A still further object of my invention is to provide a chair structure with a minimum number of parts that will carry out the objects of the invention and which will not interfere with the complete collapsing of the chair when the same is to be folded for storage.

Still further objects of my invention are the provision of a chair in which the prop or brace member may be completely removed for desired adjustment, and to provide an auxiliary support member at one end of the canvas frame, that in cooperation with the prop and brace device, will support the frame and provide a solid cot structure upon which a person may recline.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a view in perspective of a beach chair of collapsible type shown open to receive a person in seated position.

Fig. 2 is a view similar to Fig. l showing the chair structure adjusted to cot forming position.

Fig. 3 is an enlarged fragmentary view in perspective of the prop and brace structure used in attaining one of the objects of my invention.

Fig. 4 is a View in side elevation partly in section of the prop and brace structure used in connection with the invention.

Fig. 5 is a view similar to Fig. 4 showing the 2 prop and brace combination removed from the hollow brace or sleeve in which it is held.

Fig. 6 is a view similar to Fig. 4 showing the prop and brace after it has been adjusted as shown in Fig. 5 and reinserted to constitute a chair forming support.

Fig. '7 is a section on the line 'I-l of Fig. 6 showing a modified form of the prop and brace structure in cot supporting position.

Fig. 8 is a view somewhat similar to Fig. 'l showing a modified form of the prop and brace structure in cot supporting position.

Fig. 9 is a view similar to Fig. 8 showing the prop and brace parts adjusted for chair supporting position.

Referring to the drawing in detail, IIJ and II indicate respectively, the frame pieces of a collapsible beach chair which are pivotally joined together as at I2, the frame I0 seating Within the frame I I and being provided with a reinforcing cross bar I 3 to which is suitably attached one end of a panel of canvas or other material I4, forming the bottom of the chair or cot, and which is secured at its other end about a like bar member I5 reinforcing one end of the leg frame II. The latter also includes reinforcing cross bar I6 at the ground engaging end thereof and the canvas frame part I0 is also reinforced by a similar bar Il extending across the ground engaging end thereof.

The frames thus formed are substantially rectangular in shape and pivot within each other to permit collapsing of the framesinto a small area for storage or carrying. The canvas frame l has pivoted on its cross bar Il the strut pieces I8 which, when the device is used as a chair as illustrated in Fig. 1, are in alignmentl with the frame pieces I9 and are maintained in such position by suitable projections or pegs I 9 on said frame pieces. The leg frame members II are serrated as at 20 along the upper edges thereof so that the prop and brace structure to be described may be adjustably positioned therein.

In a preferred form of structure as illustrated in Figs. 3 to 7, the prop and brace unit 2| consists of brace legs 22 joined by a cross bar 23 and to the ends of which is also pvoted as at 24 the prop legs 25.

It will be noted that the brace legs 22 (Fig. 7) extend as at 26 beyond the pivot point of the cross bar 23 so that when the bracing unit is manipulated for adjustment, the end portion 26 of member 22 will lay alongside the prop member 25. End 26 or another part of brace 22 and a part of the member 25 will be housed within the casing 21 and be prevented from having relative pivotal movement.

The housing 21 is preferably made in the form of a metal sleeve of rectangular cross section provided in its upper portion with a filler block 28 and secured by a pivot pin 29 to one of the frame pieces I so that the housing 21 may have swinging movement relative thereto. The filler piece 28- acts. asl al stop flor the inserted prop or brace members and' `the' sleeve 21 "rigidly holds the prop and brace rrnly to prevent instable movements or swaying of the device when it is used as a cot or chair.

In another form of the invention illustrated in Figs. 3 and 9 the brace legs 30, only one. of which is shown in Fig. 8, are connected bythe cross rod 3l and to the opposite end of 'eachileg 30 there is pivoted as at 32 a prop 33. In Fig, 8, when the device is used asa cot and the prop and brace are relatively shortened they will be substantially parallel and will' be housed in a sleeve 34 similarto sleevev 21. vWhen the device isto be used as a chair and itis desired to raise the canvas lframe panel'land support it in chair forming positionithe' prop and brace unit are withdrawn from the sleeve 34 and the prop legs 33 opened'to align with the legs 30 as illustrated iFig. 9 for reinsertion into the sleeve 34, with the result Athat the end of the sleeve will cover the pivotal' joint 32 andprevent relative pivotal movement between the

parts

30 and 33. The depending member 30 inthis instance will engage the lnotches of the leg frame Il to firmly support the c`ot or chair 'frame l.

It is necessary in this particular structure, becaus ofthe Yamount of movement necessary to convert the chair to a cot or vice versa, to provide collapsing members inthe nature of a prop and brace which may be used efficiently in either open lor 4closed position. In the form of theI invention illustrated in Figs. 3 to 7 it is immaterial whether the lleg'structure lis extended ornot', as the sleeve 21 covering a portion of the leg22'an'd apart of the prop 25 will prevent relative pivotal movement therebetweeri.y In either the open orclosed pi'isition of the parts 30 and 33-as illustrated in Figs. 8 and 9 the sleeve 34 willhouse the pivot 32and prevent pivotal movement between the legs '33 and 33 which would cause thevcot to sway.

` It is evident, therefore, that I have provided a simplied construction of beach chair which may be used as a chair or may be quickly and easily adjusted for use as a cot or the like that will support a person in reclinmg horizontal position. My improved device may be applied to chairs already in use and does not require any mechanical knowledge for adjustment.

While I have illustrated and described the preferred embodiments of my invention, it is to be `ujnderstopd`that I do not limit 'myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defiiiedin the appended claim.

Having, thus described my invention, what I claiiii'as new, and desire to secure by United "States Letters Patent is:

A convertible beach chair, comprising a frame having longitudinal side bars and connecting end cross bars, a second frame having longitudinal side barsand connecting end' bars, the sidebars of the second framefbein'g disposed against the outer sides of the side bars of the rs't frame and pivotally connected thereto near adjacent ends of the two frames, a iiexible load supporting fabric strip secured at one end to a cross bar of the rst frame and at the other end to the opposite cross bar of the other frame, strut pieces pivotally mounted on the other cross bar of said first frame, and telescopic brace bars pivoted on the side bars of the rst frame-and having adjustable bearing on the side bars ofthe second frame, for supporting the two frames in rigid angular relation to each other whereby the two frames may be used as a beach chair or as' a cot, said strut pieces being pivoted into ground engaging position vwhenl said frames are adjusted to be used as a cot and pivoted between said'longitudinal side bars of said first frame when said frames are to-be used as a chair.
