Claims.

The present invention relates to high chairs and the primary object of the invention is to provide a chair of this type which when not in use may be readily folded into compact form for storage or transportation purposes,

A further object of the invention is to provide a folding high chair embodying novel means for retaining the chair in its extended condition of use without requiring the use of any latches or other fastening devices for preventing the chair from accidentally folding up while in use.

A further object resides in the novel tray arrangement permitting read and easy placing and removal of a child from the chair, and also the means whereby crumbs or the like may be easily removed from the tray.

A further object is to provide a folding high chair of extremely simple construction, and one wherein a safety strap for preventing a child from sliding out of the seat also serves to hold the tray rigidly in place.

Other objects and advantages of the invention will beapparent from the following detailed description taken in connection with the accompanying drawings forming a part of this specification and in which drawings- Figure 1 is a perspective view of the high chair set up for use.

Figure 2 is a side elevation of the chair extended for use, with a fragmentary portion broken away.

Figure 3 is a side elevation showing the chair partially folded.

Figurel is a side view folded condition.

Figure 5 is a vertical section thru the chair in its folded condition.

Figure 6 is a fragmentary detail section showing the manner in which the lower ends of the back portion coact with the rear legs when the chair is set up for use.

Figure 7 is a side view of the showing in Figure 6.

Figure 8 is a fragmentary detail section showing a slightly modified form of construction from that shown in Figure 6.

Figure 9 is a side view of the showing in Figure 8.

In the drawings, like reference characters designate corresponding parts thruout'the several views.

Referring first to the form of the invention shown in Figures 1 to 7 inclusive, the high chair is preferably constructed of wood and comprises a pair of front legs I0, and a pair of rear legs II which are pivoted at their upper ends as at I2 to the outside of the front legs at a location spaced below the upper ends of the front legs. Pivoted at its forward portion between the front legs In as upon the pivot pins I2 is a seat I4 of the chair in a fully having its rear portion pivoted to the intermediate portion of a back rest I5. This back rest I5 includes a pair of side members or uprights It to which the seat is pivoted at a substantial distance upward from the lower ends of the uprights. An arm rest I! is pivoted near its forward end as at I 8 to the upper end of each front leg I0, and at their rear ends are pivoted to the uprights I6 as at I9 whereby the arm rests are in substantial parallel relation with the seat I4. The front legs ID are connected adjacent their lower portions by a cross brace 20, and a suitable foot rest 2| is also mounted on the front legs below the seat I4. The rear legs I I are connected adjacent their lower portions by a cross brace 22, and also at a location slightly above midway of their length with a combined cross brace and stop bar 23 adapted to be engaged by the lower end of the uprights I6 when the chair is set up for use, As will be seen, the lower ends of the uprights I6 fit between the rear legs I I.

Pivotally connected at one end to the lower end of each upright I6 of the back I5 as by a rivet or the like 24, is a metal link 25 and which links are pivoted at their other ends by rivets or the like 26 to the rear legs I I at a location spaced below the cross brace 23. Thus when the chair is set up the links 25 swing forward past vertical center until the lower ends of the uprights I6 abut the cross brace 23 and limit further swinging of the back rest beyond a slightly upward and rearward inclined position as in Figures 1 and 2.

links 28 are of such length that when the chair is set up for use the lower ends of the links bear upon the arm rests I'I slightly forward of the pivots I I 9 and prevent the chair from being folded until the links are swung forwardly out of engagement with the arm rests. The tray proper 3| rests upon the forward ends of the arm rests I! with the side rails 30 overlying the arm rests. The links 28 also form extensions of the side rails 30 whereby the tray will more readily clear the head of a child seated in the chair as the tray is swung into or out of position in front of the child. As shown by dotted lines in Figure 2, the links 28 also enable a person to tilt the tray in front of the chair so that crumbs, etc., may be readily brushed or removed from the tray.

A safety strap 35 is fixed at one end to the inner or rear edge portion of the tray SI and is provided at its free end with a suitable snap member 36 for detachable engagement with a companion snap member 3I'secured to the under side of the seat I4. This strap 35 aside from preventing a child from sliding out of the seat also serves to hold the tray rigidly in place.

When the chair is extended or set up as in Figure 2, any downward pressure on the uprights l6 tends to force the upper end of the links 25 downward and the lower ends of the uprights forward into engagement with the cross brace 23. position for use with the back rest l extending upwardly and rearward at a slight angle. Since the lower ends of the keeper links 28 engage the arm rests ll forwardly of the rear pivots IQ of the arm rests, any tendency of the back rest to raise causes the upper end of the back rest to swing forward and thus force the lower ends of the links 28 into still greater contact with the arm rests and prevents the chair from folding.

When folding the chair the tray is first swung over the back rest as in Figure 3 and then the back rest swung forward at its upper end so that the links 25 swing rearward past center as in Figure 3. The legs Ill and Il may then be swung toward one another on the pivots 12 whereby the chair will readily fold into compact form as in Figures 4 and 5.

Referring to Figures 8 and 9, the numeral 49 designates one of the rear legs of a folding high chair such as shown in Figure l, the rear legs being connected by a cross brace M. The lower end of the upright 42 is pivotally connected to the leg 40 by a link 43 whereby the uprights operate in the same manner as do the uprights I6 in Figure 1. In this modification of the invention however the uprights do not engage the-cross brace 4|, and a cross piece 44 is riveted to the rear edge of the uprights with its ends extending beyond the uprights so as to engage the rear legs when the chair is set up for use. With this arrangement the cross brace 4| may be disposed at any desired location along the rear legs and need not bear a definite spaced relation to the point of pivotal connection of the links 43 to the rear legs.

From the foregoing it will be seen that a folding high chair has been provided embodying a novel construction whereby the chair is retained in a position for use thru a novel co-action of certain of the structuralelements of the chair and without requiring the use of separate latches or the like. The high chair may be easily folded into compact form for storage or for transportation from place to place.

Changes in detail may be made to the forms of the invention herein shown and described without departing from the spirit of the invention or the scope of the following claims.
