Cl. 297-136 4 Claims ABSTRACT OF THE DISCLOSURE A childs high chair consisting of a plurality of hollow cylinders of successively smaller diameter, a chair, and a feeding tray. The cylinders being adapted to be stacked, one upon the other, and secured together, to form a high base for the chair and the feeding tray mounted thereon. When disassembled, the several components being nestable, one within the other, to form a compact carrying package of which the feeding tray forms the cover.

The primary object of the invention is to provide a childs high chair made up of a number of separate hollow sections that can be either, nested for easy storage, and carrying, or stacked, to provide a sturdy childs high chair including a feeding tray.

Another object is to provide a device of the type stated whose several components can be used individually, or in varied combinations, to provide a bathinet, a portable baby utility case, a youth chair, or a stool.

These and other objects of the invention will be come apparent from a reading of the following specification and claims, together with the accompanying drawing, wherein like parts are referred to and indicated by like reference numerals, and wherein:

FIG. 12 is a vertical sectional view of the utility case, formed by nesting the chair component upside-down in one of the cylindrical members; and,

FIG. 13 is a perspective view of the chair crotch piece, in its unmounted condition.

Referring more particularly to the drawing, there is seen in FIG. 1 the Multipurpose Stackable High Chair that is the subject of the invention, broadly indicated by reference numeral 10, in its fully assembled condition.

The assembled high chair 10, as seen in FIGS. 1 and 3, comprises three hollow cylindrical sections, or members, 11, 12 and 13, of successively smaller diameter, which are stacked, one upon the other, to form a high base for the chair member 14 and its attached feeding tray 15.

The several components may be fabricated from any moldable or formable material, combining the required physical properties of strength, rigidity and lightness, so that the several members, when nested together to form a compact package, as described hereinafter, can be easily carried. Suggested materials are, thermo-plastics, such as polypropylene or polyethylene; or thermo setting resins, fiber-glass re-inforced, polyesters, etc.

Each hollow cylindrical member 11, 12 and 13 has a fiat top 17, continuous side walls which terminate in a peripheral flange 16, and is open to the bottom. Each cylinder top wall 17 has four diametrically spaced slot sockets 19 cast therein at the peripheral edge thereof, as seen most clearly in FIGS. 5 and 8. Each flange 16 has similarly spaced fingers 18, as seen FIGS. 5 and 6, adapted to inter-fit the sockets 19 and lock the stacked cylindrical members together, upon clock-wise rotation, as seen in FIG. 3.

It is, of course, to be understood that other means might be used to provide inter-locking of the stacked members.

The so stacked and locked cylinder members 11, 12 and 13 provide a base for the chair member 14, of a height to position a child seated in the chair at the proper height at a conventional dining table. It is to be understood that we do not intend to limit the present invention to any particular number of cylindrical members.

The chair member 14 has a contoured seat 21 and a peripheral mounting flange 16 including locking fingers 18 which inter-fit the sockets 19 of the top cylindrical member 13, to anchor the chair 14 securely on top of the so assembled base.

The front portion of the cylindrical member 13 is contoured at 23 and 24 to provide comfortable support for the legs of a child sitting on the seat 21 of the chair member 14.

Reference numeral 15 indicates a feeding tray adapted to be mounted on the top edge of the chair member 14, as seen in FIGS. 1, 3 and 4. The tray 15 has an inner opening bounded by a rim 32 and a peripheral rim 34. The inner rim 32 has a continuous slot 33 centered therein which is adapted to receive the upper edge of the chair therein, as seen in FIG. 7. The so mounted tray 15 is locked in place on the chair 14 by three spaced tabs 30 having lock buttons 31 which interfit similarly spaced holes 22 in the chair wall as again seen most clearly in FIGS. 7 and 10.

The outer rim 34 of the tray has four circumferentially spaced, inwardly extending, lock fingers 35, each of which is spaced downwardly of the underface of the tray,

and parallel thereto, a distance equal to the thickness of the flange 16 of the cylindrical member 11; for a purpose to be disclosed hereinafter.

The flange 16 of the cylindrical member 11 has four similarly spaced notches 41, cut therein, of a width to clear the fingers of the tray.

Reference numeral 27 indicates a crotch piece which is positioned at the front of the chair 14, extending in a vertical plane between the seat 21 and the tray rim 32, as seen in FIG. 1. The crotch piece 27 is centered between the legs of a child seated in the chair, and serves to prevent the child from falling or sliding forward, out of the chair.

The crotch piece 27 is removably mounted in place by means of a button 28 at its lower end which seats in a hole 26 centered in the cylindrical member 13 between its contoured sections 23 and 24, as is most clearly seen in FIG. 10. The upper end of the crotch piece has a tongue 29 which is inserted into the inner tray rim slot 33 and anchored in place by the button 31 of a fourth rim tab 30, not visible in FIG. 1, which interfits a hole immediately below the tongue 29, as seen in FIG. 13.

The so stacked and locked unit is all-of-a-piece, and the wide diameter of the lowest cylindrical member 11 provides a structure that is stable and non-tipable.

To dismantle the unit for storage or transporting, the following procedure is followed:

The tray 15 is disengaged from the chair 14 and the crotch piece 27; the crotch piece is removed; the chair member 14 is rotated counter-clockwise to disengage its locking means from the base; the cylindrical members 13, 12 and 11 are similarly released from one another.

The largest diameter cylinder 11 is inverted and made to rest on its top wall 17, as seen in FIG. 9. Cylinders 12 and 13 are similarly inverted and nested within cylinder 11. The chair member 14 is nested inside cylinder 13 with its seat 21 uppermost.

The tray 15 is then positioned over the flange 16 of cylinder member 11, with its four lock fingers 35 aligned with the four flange notches 41, and rotated until the fingers 35 clear the notches and engage the flange 16 to provide a compact package 60 having the tray 15 for a cover, with the inverted chair seat 21 acting as a closure for the central opening of the tray, as seen in FIG. 2.

The tray rim 34 has a hand-grip opening 37 and a flattened section 36, diametrically opposite the hand-grip, which acts to prevent rolling of the package 60 when it is set down on its edge.

The several members may be used individually or in varied combinations to provide the following useful items:

(1) A bathinet.-Cylindrical member 11 may be used as bathinet by inverting it, with its top wall 17 down, and filling it with water, as seen in FIG. 11. The use of cylindrical members 12 or 13 in the same way will provide smaller units.

(2) A stooL-Created by stacking the cylindrical members 11, 12 and 13, only, omitting the chair member 14.

(3) A low, youths chair.Created by using cylindrical member 13, only, as the base for the chair member 14, and omitting the tray 15, as seen in FIG. 10.

(4) A portable baby utility case.- Created by nesting the chair member 14 within the cylindrical member 13, in an inverted position, and securing them together through locking means 39, as seen in FIG. 12, and identified by reference numeral 50. The utility case can be used to carry various baby supplies such as diapers, dustingpowder, etc. A cord handle 38, for carrying the case is mounted on the side wall of cylindrical member 13.

It will now be clear that there is provided a device which accomplishes the objectives heretofore set forth.

While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof, as described and illustrated herein, is not to be considered in a limited sense, as there may be other forms or modifications of the invention which should also be 4 construed to come within the scope of the appended claims.
