UNITED STATES PATENT OFFICE CHILD S CONVERTIBLE CHAIR William H. Spriggs, Des Moines, Iowa Application July 11, 1951, Serial No. 236,179 (01. 155-38.)

3 Claims. 1

This invention relates generally to chairs for children and in particular to a combination childschair.

An object of this invention is to provide an improved combination or convertible chair for a child.

A further object of this invention is to provide a combination chair for a child in which a chair section can be equipped with wheels for use as a stroller, or supported on a base section for use as a highchair, and with the base section being constructed for support on the chair section to constitute a package container when the chair section is utilized as a stroller.

Yet another object of this invention is to provide a childs stroller in which a package container is removably supported thereon at a position directly above and spaced upwardly from the seat section of the stroller to maintain a free handling of the stroller, and the stability of the stroller against tipping movement.

Still a further object of this invention is to provide a childs chair having a. seat and arm rests therefor, in which a tray member has one side thereof pivotally supported on the front ends of the arm rests for pivotal movement to an upright position located forwardly of the seat and with the underside thereof faced rearwardly.

Further objects, features and advantages of this invention will become apparent from the following description when taken in connection. with the accompanying drawing in. which:

Fig. 1 is a perspective view of the combination. chair of this invention when used as a highchair;

Fig. 2 is a longitudinal sectional view of the chair illustrated in Fig. 1;

Fig. 3 is a side elevation'of the chair of this invention showing the relative. assembly. of the parts thereof when the chair is to be used as av stroller having package carrying facilities with certain parts broken away for the purpose of clarity;

Fig. 4 is a detail perspective view of the tray member showing its assembly relation with the chair arms;

Figs. 5 and 6 are sectional on the lines 55 and G6, respectively in Fig. 4;. and

Fig. '1' is an enlarged sectional view taken along the line 7-1 in Fig. 1. e

With reference to the drawing the combination chair of this invention is illustrated in Figs. 1 and 2 as including an upper or chair section l and a lower or base section'l l. [The chair detail views as seen section Ill includes a metal seat member I 2 having a down turned peripheral flange l3 and a back rest l4 formed with a rearwardly extended peripheral flange l6.

Arranged at opposite sides of the seat H! are av pair of combination members 17 of a substantially inverted U-shape and of a tubular metal construction, each of which has leg sections it and I9 and a base section 2i. The seat 12 functions as a connecting or brace member between the leg sections [8 and I9 and is arranged between such leg sections and secured thereto, intermediate the ends of the leg sections, by rivets 22' extended through the leg sections I8 and I9 and the peripheral flange I3. Those portions of the leg sections [8 and I9 extended upwardly from the seat [2 constitute supports for the base sections 21, which in turn, function as arm rests for the chair section Ii Also, those portions of the leg sections l8 and [9 extended downwardly,

from the seat l2 constitute the leg members for the chair section II].

The back rest [4 is secured, as by rivets 23 and 25 to a pair of transversely spaced upright tubular members 20 the lower ends 24 of which are connected, as by welding, to the rear sides of the rear leg sections Id at positions below the seat l2 and the upper ends 26 of which project upwardly from the back rest M for a purpose to later appear. The rivets 25 are extended through the rear leg sections I 9 at positions above the seat H.

The structure, as described above thus provides a childs chair which can be used in conjunction with a childs play table and like infant or juvenile furniture. 'To convert the chair section It into a highchair, the lower section II (Figs. 1 and 2.) is formed with four leg members 28. and 29 of a tubular metal construction, and with the leg members 28 being illustrated as the front legs and the leg members 29 as the rear legs. These leg members are connected together adjacent their upper ends 3| by a continuous connecting member 32 of a metal tubular construction and of a substantially square shape, with the leg members 28 and 29 being located in a corner of the connectingv member 32 and secured to the connecting member 32 by rivets 33. The lower ends 34 of the leg members 28 and 29 are suitably connected together by a transverse open brace structure indicated generally at 35.

Mounted about and projected upwardly from the upper ends 3! of the leg members 28 and 29 are tubular socket members 31. The upper ends 3| of the leg members 28 and 29 are arranged in a spaced relation corresponding to the lower ends 38 of the leg sections l8 and I9. Further, the le sections [8 and I9, and leg members 28 and 29 are formed of a like tubular material. Thus on inserting the lower ends 38 of the leg sections l8 and I9, within the tubular sockets 31, to a stop position defined by the abutting engagement of the upper end face 39 of a leg member 28 and 29 with the lower end face 4| of a leg section I3 and [9 (Fig. 2) the chair section In is positively held in a superposed position on the base or lower section II.

To convert the chair section II] into a stroller there is provided a pair of wheel and axle units, indicated generally at 42 (Figs. 1 and 7) for each pair of leg sections l8 and I9. Since the construction of a unit 42 and its relative assembly with a pair of corresponding leg sections l8 and I9 is the same in all respects, only one of such units will be described in detail.

The axle 43 of a unit 42 is comprised of two sections 44 and 46 having their adjacent ends 41 and 48, respectively, pivotally connected together at 49 for a relative hinged movement. Slidably supported on the axle section 46 is an internally threaded tubular locking member which is threadably engageable with an externally threaded locking collar 52 mounted on the 4 end 41 of the shaft section 44. Thus on release of the tubular member 5| from the collar 52, and movement of the tubular member 5| away from the pivot connection 49, as illustrated in dotted lines in Fig. '1, the shaft 43 is hingedly movable. With the tubular member 5| in threaded engagement with the collar 52, the pivot 49 is located within the longitudinal confines of the tubular member 49 whereby the shaft sections 44 and 46 are rigidly held in longitudinal alignment.

' Ground engaging wheels 53 are carried at opposite ends 54 of the shaft 43, and with the shaft ends 54 being projected outwardly from the wheels 53. Thus with the tubular member 5| in its dotted line position shown in Fig. 1, the shaft 43 is folded or broken to provide for the insertion of the shaft ends 54 within openings 56 formed in the inner sides of the lower ends 38 of the leg sections l8. On movement of the shaft sections 44 and 46 into longitudinal alignment, as shown in full lines in Fig. 7, the length of the shaft 43 is greater than the distance between the lower ends 38 of the leg sections i8 so that on threaded engagement of the tubular member 5| with the collar 52, the shaft sections 44 and 46 are rigidly held in longitudinal alignment and against withdrawal from supported positions in the leg sections IS.

The lower sides 51 of the wheels 53 are below the level of the lower end faces 4| of the leg sections I8 and the wheels 53 are located between such leg sections. Thus the Wheels 53, do not interfere with the use of the chair structure as a highchair, and on lifting of the chair section [6 off from the lower section I I, the chair section I0 is immediately available as a stroller, with the projected ends 26 of the back rest supports 20 constituting hand grips for steering and pushing purposes.

When the stroller is to be used on a shopping trip and the like the lower section II is adapted to be used as a package container (Fig. 3) on the stroller. The hand grips 26 are spaced a distance apart corresponding to the spaced relation of the upper ends 3| of the leg members 28 and 29. By inverting the lower section II, and locating such section above the chair section ID, the hand grips 26 are received within a pair of sockets 31 to a stop position defined by the abutting engagement of the end faces 39 of a pair of leg members 28 and 29 with the upper end faces 6| of the hand grips 26. This location and support of the lower section II on the upright supports 20, in no way interferes with the child seated in the chair section In and by virtue of such support being directly above the chair section In, the chair section I6 is stabilized against tipping movement. Also, with the lower section II located forwardly of the back rest |4 there is no interference with the pushing or the guiding of the chair section I0.

Packages can be carried directly within the confines of the lower section II, or in a wire basket, which as shown at 62 in Fig. 3, is supported on the brace structure 36 within the confines of the lower section I The chair section I0 is equipped with a tray member 63 (Figs. 2 and 4) which has one side 64 thereof pivotally connected, as indicated at 66 to the front ends 61 of movable extensions 68 which are slidably supported on the arm rests 2| for movement longitudinally of the arm rests. An inverted U-shape guide member 69 has the leg sections 1| thereof arranged in a straddling relation with an arm rest 2 I, so that the base section 12 of a guide member rests on the top side of the rest arm 2|. As best appears in Figs. 5 and 6 the base section 12 has the sides 13 thereof projected laterally from the leg sections 1| and an extension 68 has grooved portions 14 extended about the projected sides 13. The extensions 61 are thus slidable relative to the base section 13, and are retained against downward and lateral tipping movement by the coacting engagement of the side portions 13 and grooved portions 14 on the guide members 69 and extensions 68, respectively.

With the tray 63 horizontally disposed in an overlying relation with the extensions 66, as shown in Fig. 6, the tray is movable rearwardly to a stop position defined by the engagement of a stop portion 16 on the extension 61 with the front end 11 of a base section 12. The tray is then held against forward movement by the provision of a strap or the like 18 attached at one end 19 to the rear side of the tray 63, and at its other end 8| to the front side of the seat 12 (Fig. 2).

On release of the strap 18, and movement forwardly of the extensions 68, a child is readily removed from or positioned on the seat I 2. Also, by virtue of the pivotal support of the tray 63 at its front side 64, for pivotal up and down movement on the extensions 68, the tray is movable from its horizontal position shown in Fig. 2 to its upright position shown at Fig. 4. When in an upright position, the underside 8| of the tray member 63 faces rearwardly so that a blackboard or the like, indicated at 82, secured to the underside of the tray member 63 is available for use by a child seated within the chair. The tray member 63 is maintained in an upright position by coacting stop portions (not shown) formed on the hinges or pivot connections 66, in any well known manner. Also, the tray 63 may be removed entirely from the arm rests 2| by merely releasing the strap 18 and then moving the extensions 68 forwardly out of engagement with the guide members 69.

From a consideration of the above description it is seen that the invention provides a combination chair structure which is comprised of a few parts, and is readily converted from a juvenile chair, into a feeding chair, a stroller, a highchair, or a stroller with package carrying facilities.

Although the invention has been described with respect to a preferred embodiment thereof it is to be understood that it is not to be so limited since changes can be made therein which are within the full intended scope of this invention as defined by the appended claims.
