Patented May 5, 1942 2,281,732 “ UNITED STATES PATENT OFFICE 2,281,732 CHAIR Walter G. Uline, Nappanee, Ind. Application January 27, 1941, ‘Serial .N0..376,131' 6 Claims. This invention relates to improvements in chairs, and more particularly to high chairs for use by infants. The primary object of the invention is to pro (01. 155-471) V rungs II. ‘ The portion I‘! is'provided with a cen tral opening (not shown), and a plurality of com plementary ribs or off-sets depressions I8 are vide a chair of this character with a novel foot . rest readily and easily adjustable for use by children of various sizes and ages. A further object is to provide a chair of this character having a root rest which is adjustable impressed therein to extend in equi-spaced cir cular relation‘ around» said central opening. A bolt I 9 extends through the opening in portion I‘I. Each of the brackets I 6 supports an arm 20. Each arm has an enlarged circular head portion 2I vwhich is provided with a plurality of equi both vertically and horizontally to compensate 10 spaced circularly arranged ribs or off-sets 22 for the growth of the femur and tibia of the legs therein and adapted to inter?t with and comple of a child. mentary to the ribs I3 in bracket part IT. The A further object is to provide a chair of this character having a root rest which is supported in selected position relative to the seat by two mem bers connected thereto at spaced points, and held opposite end of each arm 20 is pivoted at 23 to the front portion of one of a pair of brackets 24 which are secured to the lower face of a foot rest 25 adjacent opposite ends thereof. in desired position with respect to the body of the chair by a single securing means. A further object is to provide a foot rest pivot It will be observed from the above that the foot rest 25 will swing bodily about the bolt I9 as a center, and that the spacing of the foot rest ed on arms pivoted to a chair below the chair from the seat, as determined by the angular posi tion of the arm 20, may be ?xed by tightening the seat, and also having pivoted thereto swinging links in bodily shiftable relation to ?xed points thumb nut 26 on screw l9 to press the faces of of a chair, and means for ?xedly securing said arms and links relative to the chair. Other objects will be apparent from the de parts [1 and 2| in tight frictional contact with their complementary ribs or off-sets I8 and 22 in inter?tting relation. scription and appended claims. In the drawing: Each of a pair of links 21 is pivoted at 28 at one of its ends to the rear of each foot rest Fig. 1 is a view of a chair in front elevation bracket 24, and is provided with an elongated longitudinal slot 29 at its opposite end. The showing the front legs broken away to clearly illustrate my improved foot rest. Fig. 2 is an enlarged fragmentary front detail slot 29 is normally slidable on screw or bolt I9 and may be secured in frictional face engage ment with arm 20 upon tightening of the thumb View of the foot rest and its supporting means. Fig. 3 is a fragmentary detail vertical cross sectional view taken on line 3-—3 of Fig. 2 and illustrating the foot rest in a raised position. Fig. 4 is a view similar to Fig. 3 illustrating the foot rest in a lower horizontal position. nut 26. This construction has the advantage of sim plicity as to both its construction and its oper ation. Thus, for example, when it is desired to adjust the position of the foot rest 25 for the Referring to the drawing which illustrates requirements of any particular child, it is neces the preferred embodiment of the invention, the numeral I0 designates the legs of a chair which 40 sary only to release the thumb nuts 26, swing are suitably interconnected by rungs I I which ex arms 20 and slide the links 21 to position the tend horizontally between adjacent legs II]. A foot rest at the desired height relative to the seat I2 is supported upon the legs I0 and in turn seat I2 and at desired inclination relative to the supports a back rest IS. A table I4 of suitable construction is mounted upon the chair by sup porting members I5 and the like. Two rungs I I extend from the front to the rear iii horizontal, and then to retighten the thumb nuts 26 to clamp the parts together. This multiple adjustability permits the indi vidual requirements of any child to be accom legs of the chair at each side thereof, and an up right metal bracket I6 extends between the for modated comfortably, and permits meeting and accommodating of changes in such requirements ward ends of said rungs I I and is secured thereto w in any suitable manner. The bracket I6 is pref member for locking each pair of cooperating erably transversely con?gured for reinforcing purposes, and extends inwardly of said rungs to provide a vertical center portion I1 inset rela tive to vertical planes of the inner edges of the as the child grows. The use of a single securing arms 20 and links 21 in proper adjustment makes for convenience of operation, simplicity, and re duced cost. Also, it will be observed that the foot rest unit may be preassembled upon the 2 2,281,732 brackets [6, to be secured to the chair as a unit by simply securing the brackets to the chair. I claim: 1. In a chair, the combination of a seat, a seat support including legs and interconnecting rungs therebetween, a pair of brackets ?xedly carried by said seat support at opposite sides thereof, a pair of arms each pivoted at one end to one of opposite ends of said foot rest, brackets carried by said seat supporting means, said arms being pivoted to said brackets, links pivoted to said foot rest spaced from said arms and having a normally slidable connection with said brackets, and means for locking said arms and links in ?xed relation to said bracket. 5. In a chair, a seat, means for supporting said seat, a foot rest, a pair of arms pivoted to ally mounted on the other ends of said arms, a 10 opposite ends of said foot rest, a pair of links pivoted to opposite ends of said foot rest in pair of links each having one end thereof pivoted spaced relation to said arm pivots, and releas to said foot rest spaced from said arms, and able means carried by said seat support for hold means for locking the pivot connection between said brackets, a foot rest having its ends pivot each arm and bracket in ?xed angular position, said locking means also looking said links in de sired relation to said brackets. 2. The construction de?ned in claim 1, where in said links have a combined pivotal and slid ing connection with the bracket when said look ing means are released. 3. The construction de?ned in claim 1, where in said last named means comprises complemen~ tary inter?tting equi-spaced offsets and projec» tions in said brackets and arms around said piv 0t, and means for clamping said brackets, arms, and links in frictional face engagement at the pivot center. 4. In a chair, a seat, means for supporting saidv seat, a foot rest, a pair of arms pivoted to ing adjacent pairs of arms and links in desired relation to said seat support, said arms having a pivotal connection with said holding means and said links having a combined pivotal and slid able connection with said holding means when released. 6. In a chair, a seat, means for supporting said seat, a foot rest, a pair of arms, a pair of links, said arms and links being pivoted at op posite ends of said foot rest in spaced relation, said links being slotted, and means carried by said seat support and mounting said arms and links, said means including a securing member pivoting said arms and passing through the slots of said links.
