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 provide 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 both vertically and horizontally to compensate for the growth of the femur and tibia of the legs of a child.

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 members connected thereto at spaced points, and held 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 pivoted on arms pivoted to a chair below the chair seat, and also having pivoted thereto swinging links in bodily shiftable relation to fixed points of a chair, and means for fixedly securing said arms and links relative to the chair.

Other objects will be apparent from the description and appended claims.

In the drawing:

Fig. 1 is a view of a chair in front elevation showing the front legs broken away to clearly illustrate my improved foot rest.

Fig. 2 is an enlarged fragmentary front detail View of the foot rest and its supporting means.

Fig. 3 is a fragmentary detail vertical crosssectional 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.

Referring to the drawing which illustrates the preferred embodiment of the invention, the numeral I designates the legs of a chair which are suitably interconnected by rungs I I which extend horizontally between adjacent legs II]. A seat I2 is supported upon the legs I0 and in turn supports a back rest IS. A table I4 of suitable construction is mounted upon the chair by supporting members I5 and the like.

Two rungs I I extend from the front to the rear legs of the chair at each side thereof, and an upright metal bracket I6 extends between the forward ends of said rungs I I and is secured thereto w in any suitable manner. The bracket I6 is preferably transversely configured for reinforcing purposes, and extends inwardly of said rungs to provide a vertical center portion I1 inset relative to vertical planes of the inner edges of the iii rungs II. The portion I! is'provided with a central opening (not shown), and a plurality of complementary ribs or off-sets depressions I8 are impressed therein to extend in equi-spaced circular relation around said central opening. A bolt I 9 extends through the opening in portion II.

Each of the brackets I 6 supports an arm 20. Each arm has an enlarged circular head portion 2I which is provided with a plurality of equispaced circularly arranged ribs or off-sets 22 therein and adapted to interfit with and complementary to the ribs I3 in bracket part IT. The opposite end of each arm 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.

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 from the seat, as determined by the angular position of the arm 20, may be fixed by tightening the thumb nut 26 on screw l9 to press the faces of parts [1 and 2| in tight frictional contact with their complementary ribs or off-sets I8 and 22 in interfitting relation.

Each of a pair of links 21 is pivoted at 28 at one of its ends to the rear of each foot rest bracket 24, and is provided with an elongated longitudinal slot 29 at its opposite end. The slot 29 is normally slidable on screw or bolt I9 and may be secured in frictional face engagement with arm 20 upon tightening of the thumb nut 26.

This construction has the advantage of simplicity as to both its construction and its operation. Thus, for example, when it is desired to adjust the position of the foot rest 25 for the requirements of any particular child, it is necessary only to release the thumb nuts 26, swing arms 20 and slide the links 21 to position the foot rest at the desired height relative to the seat I2 and at desired inclination relative to the horizontal, and then to retighten the thumb nuts 26 to clamp the parts together.

This multiple adjustability permits the individual requirements of any child to be accommodated comfortably, and permits meeting and accommodating of changes in such requirements as the child grows. The use of a single securing member for locking each pair of cooperating arms 20 and links 21 in proper adjustment makes for convenience of operation, simplicity, and reduced cost. Also, it will be observed that the foot rest unit may be preassembled upon the 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 fixedly carried by said seat support at opposite sides thereof, a pair of arms each pivoted at one end to one of said brackets, a foot rest having its ends pivotally mounted on the other ends of said arms, a pair of links each having one end thereof pivoted to said foot rest spaced from said arms, and means for locking the pivot connection between each arm and bracket in fixed angular position, said locking means also looking said links in desired relation to said brackets.

2. The construction defined in claim 1, wherein said links have a combined pivotal and sliding connection with the bracket when said looking means are released.

3. The construction defined in claim 1, wherein said last named means comprises complementary interfitting 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 said seat, a foot rest, a pair of arms pivoted to 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 fixed relation to said bracket.

5. In a chair, a seat, means for supporting said seat, a foot rest, a pair of arms pivoted to opposite ends of said foot rest, a pair of links pivoted to opposite ends of said foot rest in spaced relation to said arm pivots, and releasable means carried by said seat support for holding 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 slidable 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 opposite 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.
