This invention relates to a combination high chair made with separable parts and so constructed that the whole combination may be used or that either part may be used separately.
It is the general object of my invention. to provide a high chair which separably comprises a nursery chair and a baby walker or exercising device. A further object of the invention is to provide improved and convenient means for securing the two parts of the combination chair in assembled relation.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Referring to Fig. l, I have shown my assembled high chair comprising an upper portion or nursery chair N and a lower portion or baby walker J.
The chair N comprises a seat frame In having a hinged cover I l, and is provided with the usual back I 2, arms I and tray 15. The chair N is also provided with short legs I6 connected by side rounds l1 and by front and rear rounds 18.
A foot rest 20 may be mounted on pivot studs or screws 21 between the front legs [6 of the chair N.
The baby Walker J comprises a top frame member 36 mounted on legs 3| connected by upper and lower side rounds 32 and 33 and by upper and lower front and back rounds 34 and 35. The bottom rounds 33 and 35 are preferably bowed outwardly, thus taking the place of the usual circular outer frame. The legs 3! are preferably provided with wheels 36. The frame 3% is cut away in its middle portion as indicated at 31 (Fig. 4), and a jumper seat 38 may be suspended below the opening 3'1 by straps 39 and springs 49. When the walker J is separated from the nursery chair N, it constitutes a separate and complete walker unit and is adapted to serve all purposes of the usual baby walker.
I will now describe'the means which I have provided for detachably securing the parts in the assembled relation shown in Fig. 1.
This latching or securing means comprises clips 4| (Fig. 6) loosely connected to the ends of toggle arms 42 which in turn are pivotally connected by a stud 43 (Fig. 9). The clips 4| are preferably made of heavy sheet metal, bent to the shape indicated in Figs. 6 and 7, and are provided with elongated slots 45 through which screws 46 may be inserted into the side rounds H. The hooked ends of the clips 4! are thus loosely connected to the side rounds l! but are free to swing about the axes of the rounds H.
The lower ends of .the clips il are bent to substantially circular outline and are slotted to receive the ends of the toggle arms 42, which may be loosely retained therein by cotter-pins or other suitable fastening devices 48 (Fig. 8).
The pivot stud 43 (Fig. 9) which connects the adjacent ends of the arms 42 also extends through a pair of cup-shaped washers 50, each of which has a flange 5| provided with a segmental recess 52 in one part of its periphery. A segmental block 55 is loosely mounted in the recess between the washers 50, as indicated in Fig. 10, and forms a stop to limit downward movement of the arms 42 and pivot stud 43 when the toggle arms reach the position shown in Figs. 6 and 10. The pivot stud 43, after insertion, is headed over or riveted tightly enough to produce substantial friction between the arms 42.
When the arms are pushed downward to the limiting position shown in Fig. 6, the lower ends of the clips 4! are pushed outward under the top frame member 30 of the walker J and are securely held in this position, thus latching and securing the parts N and J in assembled relation.
During the latching operation, the bend in the middle of each clip permits the clip to yield and lengthen slightly, so that lost motion between the assembled chair and walker is avoided by subsequent contraction of the clips.
Relative sliding movement of the parts is prevented by providing cone-shaped studs 6!) (Fig. 5) in the upper surface of the frame member 311, which studs project into similar recesses 6| in the lower ends of the legs I6. The parts are thus securely held in assembled relation.
If it is desired, however, to separate the parts N and J, the arms 42 are swung upward, as'indicated by the arrow at in Fig. '7, thus swinging the clips 4! inward and away from latching position. The arms 42 may be swung upward sufficiently to swing the clips 4| above the lower ends of the legs I5, so that the nursery chair portion N of the combination may be used by itself and will rest squarely upon its own legs [5.
Having described the details of construction of one form of my improved chair, the uses and advantages of my invention will be readily understood. When the parts are separated, the chair N is immediately available as a low or nursery chair, with the latching device frictionally held in raised or inoperative position. The walker J is also then available for use as an exercising device in the usual manner, and is supported on its wheels 36, so that it may easily be moved from place to place.
When it is desired to assemble the chair N and walker J to form a practicable high chair, these parts are superposed and the toggle arms 42 are depressed, thus latching the parts together and positively maintaining them in locked position. The assembled combination is then perfectly adapted to serve all purposes of an ordinary high chair.
In Figs. 12 to 16 inclusive I have shown certain modifications of the lower or walker part of the combination, but the method of securing the parts together is substantially the same.
In Figs. 12 to 14, the walker J has an upper frame member Til which is circular in outline and which is secured between the upper ends of the walker legs H by screws 12, the edge of the frame being preferably notched into the inner faces of the legs for additional support. In this construction, the conical studs 15 are inserted in the upper ends of the legs 12, instead of in the top face of the frame H1. The clips M of the fastening device engage under the frame and hold the parts firmly assembled, all as previously described.
In Figs. and 16, I have shown an additional modification in which no topframe member is provided for the portion J but the upper ends of the legs 80 are connected by side rounds 8| and front and rear rounds 82, the jumper seat being omitted. The lower ends of the clips 4| engage under the side rounds 8|, as shown in Fig. 16, instead of under a top frame member.
The operation of the latching device is, however, identical in all three constructions, and the nursery chair and the walker section are firmly secured together but are readily detachable when so desired.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
1. A high chair comprising a baby walker, a nursery chair, and a latching device on said chair detachably securing said chair in superposed assembled relation on said walker, said latching device comprising a pair of holding clips mounted to swing in opposite directions on lower parts of said chair and having lower end portions ofiset in opposite directions and engageable below upper parts of said walker at opposite sides thereof, and toggle means to move said clips apart to complete such engagement and to lock said clips in holding position.
2. The combination in a high chair as set forth in claim 1, in which the clips are formed of resilient material and are capable of yielding elongation on engagement with said upper parts of said walker and thereafter yieldingly retain the assembled parts under spring tension.
3. A high chair comprising a baby walker, a nursery chair, and a latching device on said chair detachably securing said chair in superposed assembled relation on said walker, said latching device comprising a pair of holding clips mounted to swing in opposite directions on lower parts of said chair and having lower end portions offset in opposite directions and engageable below upper parts of said walker at opposite sides thereof, a pair of toggle arms connecting said clips and movable downward to move said clips apart to complete such engagement, and limiting means effective to prevent downward movement of said toggle arms substantially beyond their operative position, whereby said clips are locked in holding position.
4. The combination in a high chair as set forth in claim 3, in which the limiting means comprises a cupped washer assembled with each arm and peripherally slotted to receive said arm, said arms and washers all having a common pivotal connection and said washers having their cupped surfaces abutting, and a floating segmental block mounted between said washers and engaging and locking said arms against further relative angular movement as said arms pass dead center in downward latching movement.
