FOLDINC HIGH CHAIR Filed Nov. 12, 1948 21 4 IN V EN TORI g; f7 6. 6 $255 0!" $22312 0 %%%Mflwmwz W ATTORNEYS within the latter with a pair of downwardlyextending or pendent leg-supporting

lugs

22, 22, the side flanges 2i, 2! extending into the

undercut portions

23, 23 of slots 15 in each case.

Between each pair of

lugs

22, 22 on the slidable bracket members H is pivoted the upper end 24 of rearwardly and outwardly-inclined legs 25 by means of pivot pins or bolts 25. Within the lower ends 21', 2'5, both legs are connected together by a cross-piece or tie rod 28, the lower ends 2? of these legs extending far to the rear of the seat 8, and as both legs 25, as well as the forwardlyextending legs it also extend toward the sides, they together cover a wide leg base for the seat which will tend to prevent tipping of the chair in use. It is evident from viewing Figure 1 that when the seat is in normal horizontal position, it will tend to urge and hold the brackets H in forward position against the stop cleats E8 in slots 15, while all four legs are disposed in their extreme extended positions on the floor. The rear legs 25 last described are disposed exteriorly of the front legs it, it and are arranged in crisscross relation with respect to the latter, the two pairs of legs being pivoted together at their crisscross points by means of an intermediately-disposed securing element or cross-rod 29 which at the ends extends through an inner leg it and an outer leg 25 with a washer or spacing member til disposed between the two in order to maintain a proper spacing of the legs and prevent wobbling or dislocation during folding of the chair.

Within the front edge 3| of seat 8 is secured a long hinge 32 to the bottom of said seat by means of screws or the like and to this hinge is secured a depending footrest as terminating at the lower end in a foot-supporting ledge 35. At the lower end of the intermediate portion of depending footrest 3 5 is mounted a bracket member 36 by means of screws or the like (not shown), and to bracket member 36 is pivotally connected the forward end of an adjustable brace 3"! by means of a pivot pin or bolt 38. Beneath the rear end of brace 3'! the latter is formed with a series of downwardly-open slots resulting in teeth 40 intermediate said slots forming stops adapted to engage with the cross-rod 29 which interconnects the two sets of legs, the footrest 3 5 with its foot-supporting ledge 35 being swingable upon the hinge 32 beneath seat 8, while the brace 3'! connected to the lower end of the iootrest support is adapted to be shifted from slot to slot 39 for adjusting the foot support 34 into various positions more or less in advance of the forward edge 3| of seat 8 or in any select position of support with respect to seat 8, the foot support being naturally projected to its maximum forward extension when the rearmost slot 39 is seated upon the cross-rod is and brace 3'? remaining in place by gravity upon the cross-rod. It is self evident that the adiustment of the footrest support 34 is quite independent of the operation of either folding or opening out of the chair, for when the chair is once opened and placed in position with the lower ends 153 and 2! of legs l0 and 25 in proper position upon the floor, the footrest may be adjusted by lifting the rear end of brace 31 and causing it to engage in the particular one of the slots or notch means 39 upon cross-rod or securing element 29 and the footrest 34 will then remain in attained position.

At the rear, the 3 is formed with a plurality of spaced slots M, i! resulting in a series of equidistantly spaced, rearwardly extending fill iseat lugs t2, 42 occupying the entire rear end of the seat. Extending down between the

lugs

52, 42 on the seat in the slots ll, H, etc., of the latter, are a corresponding series of downwardly-

pendent back lugs

43, 43 integral with the back id of the chair. Through all of the lugs and 18 extends a long pivot red at in such fashion that the back G l may be hinged downwardly toward the rear of seat 8 into substantial alignment therewith when the chair is to be folded into idle condition.

However, in order to ensure a proper operative position for the back i l, and incidentally in order to maintain the chair as a whole in extended operative position, upon the intermediate portion of the rear of seat 8 a spring it is secured an aperture 39 Within the rear end 43 adapted to receive a locking member orlocking means 50 depending integrally from a bracket 5! secured to the lower end and rear portion of the back i l by means of screws, bolts or the like (not shown). lhe arrangement is such that when the back member M5 is in idle extended position lying rearwardly of seat 8, thelower portion of the bracket 5! and also the locking projection lit thereof occupy the space 52 out into the rear end of seat 53 to form a clearance chamber to receive the mentioned parts without obstructing the same or in any way inhibiting movement of the back t l upon the pivot rod 55. When the back M is erected into the generally upright position shown in Figures 1, 2 and 4, the locking projection it! will push the outer end 68 of spring 46 down ward to a suii'icient extent to allow the mentioned locking member to ultimately register with aperture 19 in the spring when the latter will suddenly approach the bracket 5| and cause the locking member to project through aperture 49, preventing further movement in either direction of the back 34, thus locking the latter in its attained position. If the outer end it of spring 4 8 is manually drawn downward so that the spring clears the lower end of the locking member 513, it will then be possible to lower the back 4 rearwardly of seat 8 when the chair is to be folded or collapsed. To the side edge of back M, a short distance above seat 8 are pivotally mounted a pair of arm rests 53, 53 at the rear ends 54 thereof by means of screws or bolts 55. Upon the under side of each of the side arm rests 53 and within the forward end 56 of each is secured a hinge 5'! by means of screws or the like (not shown), and to the hinges 5'7 are secured depending arm braces or supports 58, 58 for swinging movement about an axis transverse of the arm rests. The mentioned braces or supports 58 at their upper ends are cut in such fashion as to present an acute angle at 59 toward the rear in order to cause the members to incline forwardly from a directly downwardly-extending position. and virtually form stops engaging against the under side of the arm rests 53. At the lower ends of braces 53 pivot pins or bolts lit pivotallv connect the braces to a pair of depending lugs 5!, 6i fixed to the under side of the seat at the sides and immediately within the forward ends iii of the sides by means of screws or the like (not shown), so that the braces 58 will pivot on the bolts E59 when the chair is being folded into its idle condition.

From the foregoing, it is evident that all parts of the folding high chair which have been described are linked or pivoted together in such manner that when desired the chair may be folded together or opened out into operative position. For example, if it is assumed that the high chair is folded into its most compact condition, as shown in Figure 3, in which the back it is shown substantially in line with and depending from the rear or lower end of seat 8, the back 54 may be raised to cause the looking projection 59 to engage with spring 98 and particularly engage in the aperture 99 of the spring, the raising of the back id automatically also raising the arm rests 53 spacing them from the seat 8 with simultaneous raising of the arm rest supports or

braces

58, 58. The legs I0, It may then be pulled or swung out toward the left from the legs 25, which will cause the bracket members 1?, IT to slide forwardly toward the forward ends l6, E9 of the side portions of seat 8 in slots l5, 15 until the legs assume the position shown in Figure 1 when the bracket members I! will come to rest 9 against the lugs or cleats l9, H3 in the slots IE, 15. Thereafter the brace 31 connected to the lower portion of footrest 34 is brought under the seat above cross-rod 29 and then brought down upon the latter with one of the slots 39 seating upon rod 29 and fixing footrest 39 and foot ledge 35 in position, when it will be found that the chair as a whole is in position to receive a child upon seat 8 between arm rests 53, 53 in such position that the feet may rest on ledge 35 and the child rest its back against the seat back 94.

Folding the chair together is virtually a reversal of the foregoing steps, the brace 31 being released from cross-rod 29 and allowed to hang down from bracket 36 at the lower end of footrest 34 when the

legs

19 and 25 can be swung together, sliding bracket H rearwardly toward the rear fixed

brackets

9, 9 of the seat in slots I5, I5, after which the finger may be applied to the outer end 38 of spring 46 to release the latter from looking projection 59 at the lower end of back 44 when the latter may be swung rearwardly into line with seat 8 which automatically also folds down the side rests 53 and supports 58 thereof close to the sides of seat?! when a final folded condition of the chair shown in Figure 3 will be attained. In this folded compact condition, the chair is obviouslyreadily placed in a closet or behind a sofa, or in any other unobtrusive place of storage.

Manifestly, variations may be resorted to and parts and features may be modified or used without others within the scope of the appended claims.
