coLLAPs1BLE CHAIR' AND y THE LIKE.

To all whom t may concern.'

Be it known that I, ADDIs E. ALBERTIE, a citizen of the United States, residing at Detroit, in the county of *Wayne and State of Michigan, have invented certain new and useful Improvements in Collapsible Chairs and the like, of which the following is a specification.

Myiinvention relates to improvements in collapsible chairs, tables, and similar. furniture, and has for its object theprovision of a portable, collapsible piece of furniture thatcan be quickly and easily setup, and readily folded intoa compact parcel. y

A further obi ect is to provide acollapsible chair or the like of great strength though of little weight, and one which will be efhcient and durable in use and inexpensive to manufacture.

With the above and other objects in view,f

which will readily appear as the inventionis better understood, my invention consists in the novel construction, combination kand arrangement of parts to be'hereinaftery more fully described and particularly pointed outv in the appended claims. v

Reference is to be had to the accompanying drawings illustrating preferred embodiments of my invention and wherein similar reference numerals designate throughout the several views.

1n the drawings Figure 1 is a side elevation of a collapsible chair constructed in accordance 'withmy invention and in position for use ;`y Fig. 2 is a side elevation of the foldable supporting member in closed position;

Fig. 3 -is a detail planview of the upper end of one of the seat supports;

Figs. 4 and are plan view be hereinafter described;

Fig. 6 is a side view ofthe upper end of the kseat supports with a seat -rod secured therein; 1 l

Fig. 7y is a perspectiveview of -a slightly changed modification of the chair in open position; j

Fig. .8 is a detail viewof the hinge connecting the parts forming the seat andback;

Fig. 9 is a detail side elevation of anotherl F ig.v 10l is a similar viewiwith `parts iny closed position; vand simi-lar .parts s of details to Viewk yof they back supwhich are 7 adapted to be lconnectedywith the corners of the seat or table portion 8. Both the legs 6 and seat supporting arms 7 are preferably constructed of channel section to give lightness and strength, and each arm y7 when folded lits over the leg Y6 to whichv it kis pivoted, as shown in Fig. 2.. 1`heA free ends of the supporting arms 7 are slotted, as at 9, toreceive lugsk or bolts 10 carried by the ,side gods 1)1of the seat or table portion 8 (see iig. 6 *.1

VThe pins lor Lbolts 12 which connect the legs 6 to the arms pass through openings in the frame 13 fixed on the upper end lof a hollow central post 14,l to the lower end of which are pivoted locking rods115 adapted when the chair is in use to prevent spreading of the legs under the `weight Aof the person seated thereon. These rods in the modi- Specification of Letters Patent. o Patented J 1111322, 1920, I Application filed :rune 1s, 1919, serial No.

icationshown in Figs. 1 to`6 are provided Y in `Figs. 7 to 10 are formed of jointed sections 18 and 19-pivoted to each other and to the legs 6 and central post 14 respectively;

Extending through the central post 14 is anormally vvertical lbolt'20 carrying atits upper end alocking plate `21 provided with grooves 22 arranged to lit over the supporting arms. 7 when in openk position. In the embodiment illustrated in Figs. 1 to 8 the weight of the bolt and nuts serves to hold the plateinengagement Lwith the supporting arms, while inI the modification illustrated in Figs. 9 and 10 a spring 23 is utilized to assist in holding the 'locking plate down.

Theseat or table portion of `the piece of furnitureis preferably madeof canvas orl yother fabric, provided with side rods to 85 (see Fig.. l), and in the modification shown n f into the slots 9 on the free ends of ythe supporting arms 7 when the chair or table is in position for use. These slots are prefer,- ably of the type illustrated in Fig. 3, and permit the ready detachment of the lugs and seat portion from the supporting arms 7 when desired. Pivoted to the side rods 11 aare the side rods 25 of a back portion 8, also of canvasor similar fabric, and to maintain the back in proper position, when the chair is in use I preferably provide a limiting cord or chain 24, the ends of which are connected to the seat and back portions respectively. The upper edge of the back portion 8L is reinforced by a rod 26, pivoted at one end to one of the side rods 25, while its opposite end is adapted to fit into an eye 27 formed in the other side rod. The canvas portion carries snap-fasteners 28 to secure the flap 29 of the back SiL in position over the upper rod 26. When the device is to be used as a table the back `portion 8a can be folded down on top of the seat portion 8, or, by detaching one of the retaining cords 24, can be opened into parallel position with the seat portion and supported at its free end by an additional prop or supporting member.

The operation of my improved collapsible furniture is believed to be apparent from the foregoing description. Then in folded position, as shown in Fig. 2, the legs 6 fit within the channels of the supporting arms 7 and set in alinement with the central post 14. The seat and back portion is detached from the supporting member and can be rolled around the folded supporting member 5, the upper rod 26 of the back portion being swung into alinement with the side rods 25 before rolling. To set up, the seat and back portion in unrolled from thev supporting member, the arms 7 are swung upwardly into the position shown in Fig. 1 and the hooks of the locking rods 15 are brought into engagement with the cross pins 17 in the legs 6, and the grooves '22 of the locking plate 21 are fitted over the arms 7 in their raised position. The lugs 10 of the rods 11 of the seat portion are then inserted into the slots 9, the back portion 8a is swung upwardly, and the upper rod 26 is swung Y into position within the flap`29f. The chair is then in position for use. ln the modification showninFigs. 9 and 10 the locking rods are always connected with the legs 6 and the central post 14 so that it is unnecessary to swing thehooks into engagement with the pins on the legs. This simplifies the operation of setting up the chair. Also the spring 23assists in holding the locking plate 21 in engagement with the arms 7 .in their raised position.

While it will be apparent that the illustrated embodimentsof my invention herein shown are well calculated to adequately fulfil the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the scope of the subjoined claims. A i
