CONVERTIBLE CHAIR.

To all whom it may concern:

Be it known that I, Gnonon W. RUNDLE, a citizen of the United States, residing at Spokane, in the county of Spokane and State of TVashington, have invented certain new and useful Improvements in Convertible Chairs, of which the following is a specification.

This invention relates to chairs which are convertible, and its object is to provide a novel and improved childs high chair which may be converted into a low wheeled or rolling chair.

The herein stated object is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawings for a better understand ing of the invention.

In the drawings Figure 1 is a perspective view of the high chair; Fig. 2 is a side elevation showing the chair converted into a low wheeled or rolling chair; Figs. 3 and 4 are details in perspective showing portions of the seat structure.

Referring specifically to the drawings, the chair has front and rear legs 10 and 11, respectively, a pair of each of said legs being provided. The front legs are connected at the bottom by a cross-piece 12, and the rear legs are connected by rungs 13. The front and rear legs converge upwardly, and the rear legs are longer than the front legs, their upper ends terminating some distance above the corresponding ends of the front legs. The rear legs carry, adjacent to their respective ends, rollers or small wheels 14, the same serving as a rolling support when the rear legs are placed in horizontal position, next to the floor, and the chair is converted into a low chair.

The front legs 10 are pivoted at 15 to seat supporting members, the same being fiat plates 16. To the rear legs 11, intermediate the ends thereof, are rigidly secured arms 17, which extend forward and are pivoted at their outer ends at 18 to the plates 16. At the bottom edges of the plates 16 are abutments 19 which are engaged by the inner edges of the front legs, adjacent to the pivots 15, to prevent said legs from swinging out of supporting position.

The plates 16 and the rear legs 11 are connected by braces 20, pivotally connected to said parts, the pivotal connection with the plates being indicated at 21, and the pivotal Specification of Letters Patent.

connection with the rear legs at 22, the latter being near the lower ends of said legs.

The braces are slotted to accommodate the pivots 22, in order that they may be folded. The braces extend diagonally between the plates and the rear legs. To prevent the legs 10 and 11 from spreading, foldable con necting links 23 are provided between the front legs 10 and the braces 20, said links being pivoted, and having a slotted connection with the braces to permit folding, as shown in Fig. 2.

The seat of the chair is indicated at 27. To the front and rear ends of the seat are pivoted uprights 28 and 29, respectively, carrying arm rests 30. The pivots of the front uprights are indicated at 31, and those of the rear uprights at 32. The arm rests are pivoted to the upper ends of the up rights. To the rear end of the seat is pivoted a back rest 33, as indicated at 34:, provided with a locking bail 35 for holding the same at different angles, said bail being adjustably connected to the arm rests, the latter having slots 36 providedwith retaining shoulders 37 engageable by the bail branches. The rear ends of the slots limit the downward swing of the back rest. The pivotal connection between the uprights, the arm rests and the back rest enables these parts to be partly collapsed or folded, the uprights and the back rest swinging in parallelism.

The seat 27 is supported at its rear end on fishaped springs 38 made fast to a crossbar 39 connecting the intermediate portions of the branches 40 of a yoke. These yoke branches are connected to the front of the seat by the pivots 31 and they extend rearwardly beneath the seat, to the crossbar 39, where they have a downward bend terminating in a connecting cross-piece 41. The lower ends of the front uprights 28 extend below the seat 27, and to said lower ends are pivotally connected, as indicated at 42, foot rest supporting bars 13, the foot rest being indicated at 4 1, the same having a rearward and upwardly extending portion 45 which is connected at its upper edge by rods 46 to the rear ends of the bars 43.

The seat is removably connected to the plates 16 by the following means: To the branches 40 of the seat supporting yoke, between their connection 31 with the front end of the seat and the springs 38 supporting the rear end of the seat, are rigidly fas tened depending plates 51 having outstanding pins 52. The plates 16 have outstanding horizontal flanges 53 at the top provided with slots 54 at their junction with the plates, and in said plates are slots 55 extending downward from the middle of the slots 5-1. The plates 51 are designed to be slipped down through the slots 54:, the pins 52 seating in the slots 55. Thus, the seat is removably connected to the plates 16. In order to hold the plates 51 against upward movement out of the slots 54:, a yoke 56 is pivoted to the plates 16 at 57, the branches of the yoke having hooks 58 which are slipped over the pins 52, the latter projecting a sufficient distance from the plate 16 for this purpose. Upon swinging the yoke upward, the hooks slip off the pins and the seat may then be disconnected from the. plates 16.

The voke extends rearward from the plates 16. The chair seat 27 is also provided with a removable tray 59.

To convert the high chair shown in Fig. 1 into the wheeled or rolling low chair shown in Fig. 2, the legs 10 and 11, and the braces 20 and 23 are folded together, and swung to come beneath the seat 27, with the rear legs 11 next to the floor as shown. The pivotal connection of the rear legs with the plates 16 enables this to be readily done. When the chair is thus converted, the rear end of the yoke 40 seats in notches in plates 60 carried by the legs 11, and thus serves to prop up or brace the seat, and prevent the same from tilting rearward about the pivot 18. li'orward tilting is prevented by the braces 20 extending between the plates 16 and the forward ends of the legs 11.

I claim:

1. A convertible chair comprising a seat, supporting members carrying the seat, front and rear legs pivotally connected to said members, the rear legs carrying wheels and being adjustable into horizontal position to provide a wheeled support for the seat, a

rearward and downwardly extending prop member extending from the seat and engag ing the rear legs when in horizontal posi-- tion, and pivoted brace bars extending between the supporting members and the lower ends of the rear legs, said brace bars extending between the supporting members and the front portions of the rear legs when the latter are in horizontal position.

2. A convertible chair comprising a seat, a yoke connected to the seat and extending beneath the same, said yoke having a rearward and downwardly extending portion, supporting members to which the yoke is connected, front and rear legs pivotally connected to the supporting members, the rear legs carrying wheels and being adjustable into horizontal position to provide a wheeled support for the chair, in which position of the rear legs the aforesaid downwardly extending portion of the yoke engages the rear portion of said legs to serve as a prop for the seat, and pivoted brace bars extending between the supporting members and the lower ends of the rear legs, said brace bars extending between the supporting members and the front portions of the rear legs when the latter are in horizontal position.

3. A. convertible chair comprising supporting members having vertical slots and top horizontal flanges provided with slots, a seat, a support for the seat having plates which pass through the slots of the aforesaid flanges and have outstanding pins working in the first-mentioned slots, hooks carried by the supporting members and engageable with the pins, and legs carried by the supporting members.

In testimony whereof I afiixmy signature in presence of two witnesses. I

GEORGE W. BUNDLE.
