2. the depth of its seat may be adjusted with respect to the back; and
3. both the height as well as the depth of the footrest are adjustablc.
Referring more in detail to FIGS. 1 through 4, the chair-stabilizing base framework Aa comprises a pair of side members each comprising pa i ts l and 1' and each having a tubular sleeve 2 extending upwardly therefrom and provided with a setscrew or the like 3. The side members of base framework Aa are mounted on casters 4, and are interconnected by crossrods 5 which are secured in position by screws 6 inserted through holes 6 in the side members and threaded into the ends ofthe rods 5.,Screws 6 also secure to each side member a bumper 7 having apertured brackets 7' through which screws 6 extend, bumper 7 including reentrant flexible ends 7". These reentrant portions 7" may comprise rubber gaskets.
The upright rear supporting framework Ba comprises a pair of elongated rods 8 each inserted into a respective sleeve 2 and secured therein by the associated screw 3. Near their upper ends, rods 8 are interconnected by a crossrod 9 which is welded thereto, and handhold knobs 10 are provided on the upper ends ofthe rods 8.
The slide Ca is mounted on rods 8 for adjustment longitudinally thereof and, for. this purpose, comprises a pair of sleeves lll interconnected by crossmembers l2, 12. Slide Ca is secured in adjusted position on upright supporting framework Ba by means of setscrews l3, 13. Slide Ca disengageably sup ports the small armchair Da.
Armchair Da includes a bottom sent support 14 having on its upper surface a pair of longitudinally extending guides IS. A pair of arms 16 are secured to opposite sides of seat support 14 and to the back of the armchair, which latter is supported with its bottom edge spaced somewhat above the guides I5, as will be clear from FIG. 4. Seat Ea is provided, on its under surface, with a pair of guides 17; 17 which are complementary to the guides 15 and provide for longitudinal adjustment of seat Ea with respect to seat support M. Guides 17 are provided with respective stops or abutments I7, and guides 15 are provided with abutments 15', the abutments l5 and 17' limiting the magnitude of the relative adjustment of seat Ea longitudinally relative to seat support 14. It will be understood that guides 15 and 17 may be replaced by other similar guide means, such as pads, rollers, or the like.
Support Fa for footrest Ha comprises a tube 24 which is bent into-a rectangular U-shape, each of the opposite legs being bent at a point somewhat spaced from the bight to provide generally horizontal leg portions and generally downwardly extending leg portions. Notches 24' are provided in spaced relation along each generally horizontally extending leg portion, and apertures 24" are formed in each downwardly extending leg portion. Notches 24' are formed in the undersides of the horizontally extending leg portions, for a purpose to be described.
Device Ga, for the displacement in depth of support Fa of the footrest, comprises two L-shaped or angle side plates 20, fixed to the armrests 16 of the small airmchair and having tubes or sleeves 21 welded to their horizontal legs.
Tubes 21 slidably receive the ends'of tube 24, and the latter may be fixed in several adjusted positions by small hairpin springs 23 secured on seat support 14 and having legs acting through slots 22 oftube 21 against notches 24 oftube 24.
Frame la supporting footrest Ha comprises a generally rectangular U-shaped rod 25 with substantially vertically extending legs and with a bight portion bent to extend horizontally. Rod 25 has hook-shaped ends and is provided with pro jecting pins 25'. The bight portion of rod 25 is provided with aper ured brackets 26 welded thereto and brackets 26 are arranged to have footrest Ha disengageably secured thereto, as by SI rews or the like. The hook-shaped portions 25 and 25 are engageable in the apertures 24" of support Fa, for vertical adjustment of footrest I-Ia relative to small armchair Da.
The devices Ma are in the form of two L-shaped or angle plates, fixed to the back of the small armchair, and having vertically extending tubes welded thereto. These tubes receive the vertical legs ofa pair of hooks l8 and 19, these legs being welded together in such a way that books 18 and 19 extend at right angles to each other. The books 18 serve to support the small armchair on the upper crossmember 12 of slide Ca, with the back of the small armchair engaging the lower crossmember 12. When the small armchair is removed from slide Ca, the double books may be turned so that hooks 19 extend rearwardly for mounting the small armchair on the back of a car seat.
Finally, the tubular frame Sa supporting board or tray Ta is disengageably connected to the small armchair so that tray Ta may be turned over or inverted with respect to the latter.
A further improved embodiment of the high chair forming the subject matter of the invention is shown in FIGS. 5 through 9, and has the following features:
a. the base framework and the rear support one are made in one piece preferably of metal, shaped so that the high chair is perfectly balanced and cannot be turned over by the child;
. the frame has-fixed thereto and detachable therefrom the supporting board or tray, which can no longer be inverted but is connected to the small armchair for longitudinal adjustment and is removable therefrom;
. the vertically adjustable sliding device has the upper horizontal tube outwardly bent so as to permit a better arrangement of the small armchairm, once it is removed from the supporting framework, against the back of the car seat;
d. the seat of the small armchair has fixed underneath it, in the rest position, a tubular U-shaped support outwardly rotatable so as to permit placing of the small armchair, once removed, even on the floor;
e. the footrest is in one piece with its frame, it may be ad justed longitudinally and it is removable the same as the frame supporting the board or tray; and
f. the seat is provided with a front extension which serves as a cover for the footrest.
As may be seen from FIGS. 5 to 9, the high chair comprises a base framework A movable on four wheels A, and in one piece with a rear supporting framework B, on which are provided suitable handles L to lift it or displace it.
A slide comprising two horizontal tubes G connected to two vertical sleeves C, is vertically slidable, together with the small armchair disengageably mounted thereon, along the posts of support B, since sleeves C surround these posts and may be fixed thereto in any position desired by means of suitable setscrews.
The upper horizontal tube G is outwardly bent so as to facilitate,as mentioned, its location at the back ofthe car seat.
The small armchair itself comprises a back D and two side ortions D,, D,, as well. as a seat E preferably made of plastic material which is flexible and washable.
The seat E is provided with a front extension E which serves as a cover for the footrest.
Parts D, D, and D are fixed respectively to plates Q, R, P of molded, rigid, plastic material, which are arranged on the outer surfaces ofthese parts.
These plates are provided with axially spaced hinging sleeves Q,,, R, and P which are arranged to receive hinge pintles M which are also so formed so as to constitute the elements for mounting the small armchair on the vertically adjustable slide or on the back of a car seat. Plates R and P are formed, additionally, with horizontally extending sleeves R and P,,, respectively, on their inner surfaces adjacent their upper edges. These sleeves receive the arms of a substantially rectangular U-shaped frame S supporting tray T. These arms are secured in adjusted position in their respective sleeves R and P,, by means of setscrews V threaded through apertures in the respective sleeves. Thus, tray T may be adjusted longitudinally of the small armchair or may be completely removed therefrom.
On their lower edges, slide plates R and P are formed with suitable means for receiving the hook ends F, ofa frame F for supporting seat E. The lower edges of these plates R and P are further formed with respective sleeves R and l for receiving the arms H of a substantially rectangular U-shaped footrest H. Arms H may be secured in adjusted position in their respective sleeves by means of setscrews V" threaded into the sleevesyand the footrest is completely disengageable from the plates R and P. Handles Z are provided on the outer surfaces ofthe plates R and P.
Frame F for supporting seat E includes a longitudinal frame member which is formed with an elongated slot F whicl slidably receives a threaded pin on the underside of seat E, thi pin being provided with a suitable nut whereby seat E may bt secured in adjusted position on frame F or may be completely removed therefrom.
The frame S supports a plate 8, also made of metal, for the child to play, and is adapted to support also a tray T of plastic material which may be connected thereto (see FIG. 7) by means of projections T The underside of tray T, adjacent its forward edge, is provided with formations cooperable with the bight of frame S, and, adjacent the rear edge of its under surface, tray T is provided with a slotted bracket T, or a strap or the like which may also extend through a slot in the extension E ofseat E (See H08. 5 and 7).
A U-shaped tube U is pivoted to brackets on frame F and normally rests against the under surface of seat E. When the small armchair is removed from the slide C-G, the chair may be supported on the floor or the like by swinging the bracket U downwardly so that this bracket, in cooperation with the footrest H supports the small armchair.
The elements M, as best seen in FIGS. 6 and 9, have relatively elongated rectilinear legs which extend through the hinge portions on the back plate Q and the side plates R and P to pivotally interconnect .these portions. However, such pivoting is prevented by engagement of the hook ends F, of frame F with the side plates. The elements M are retained in position by means of cooperating setscrews and nuts V', as best seen in FIGS. 6 and 8. The upper ends of these elements M are bent to form relatively large hooks M, which may be used to support the small armchair on the back ofa car seat. Intermediate its ends, each element M is provided with a smaller hook M in the form of an apertured angle plate, and these hooks M engage over the upper crosspiece G of the vertically adjustable slide to releasably support the small armchair on the upright framework B. The elements M are rotatable so that either the hook M, or the hook M, may project rearwardly from the small armchair. When the elements M are swung to a position wherein the hooks M project rearwardly, the hooks M, rest in grooves or recesses Q ofthe plate 0.
