`to be washed and treated by disinfectants, and
`having a base board I2.
`On the seat board 25 two straps ll are fastened
`in any convenient manner and each strap is pro
`vided adjacent its outer end with an eye slot H8.
`The seat i 5 is placed removably on the seat board
`25 and is securely held in position against ac
`cidental displacement by the arm supports It,
`which are fastened to and extend upwardly from
`the seat board 25, and engage recesses in the
`seat !5 as indicated in Figures 1 and ii.
`In Figure 1 a straight chair, and in Figure 2
`a nursery chair consisting of a combination of
`this unit it with a low support frame [9 is
`shown which consists of two side boards 2&3 form
`ing the legs of the frame is and a top board 2 I, to
`which side boards are fastened in any convenient
`and desired manner. As clearly shown in Fig
`ure 3 the center portion of the top board 2| is
`provided with a cut-out open toward the back
`and formed semi-circular at the front and hav
`ing a circumferential ?ange 22 adapted to sup
`port a bowl 23 or the like, which can be slid into
`the cut-out from the back. Approximately on
`the transverse center line of the top board 2|
`a hole is is provided in said board adjacent each
`side edge thereof.
`The seat board 25 has the same outside dimen
`sions as the top board 2| and is provided with a
`circular hole 26 therein arranged concentrically V
`with the semi-circular portion of the cut-out in
`top board 2!. Inter-engaging means on the seat
`board 25 and the top board 2| hold the seat unit
`in position on the top board, said means-embody
`ing two round pegs 21 which extend downwardly
`from the seat board 25 and engage the holes 24
`in the top board 2!. On each side edge of the
`top board 2! a securing element like a button,
`knob 28 or the like is fastened and is adapted to
`engage the eye slot l8 of the corresponding strap
`H on the unit it. The knobs 28 are located sub
`stantially on the vertical transverse plane of the
`frame l9.
`Each arm I3 is provided with a plurality of
`transversely extending slots 29 in its lower sur-‘
`face and located in the forward half of said arms.
`In Figure 4 a high kitchen stool at is shown
`having the usual four legs 3| with brace rods 32
`extending between them to stiffen and reinforce
`them. The stool has a top board 33, and be—
`tween the rear legs 3! a plurality of steps 34 are
`arranged to permit the use of the stool as a step
`ladder. Underneath the top board 33 of the
`stool and adjacent the front edge thereof a foot
`rest 35 is pivotally arranged and has an adjust

`My invention relates to chair constructions
`and more particularly to chairs adapted to be
`used by children.
`The object of my invention is to provide a chair
`construction which can be adapted for a plu
`rality of purposes in the use by children.
`Another object of my invention is to provide
`a chair construction the seat and back whereof '
`are removable as one unit from their support
`without the use of any tool.
`A further object of my invention is to provide
`a chair construction consisting of a plurality of
`units, each of which can‘ be used individually for
`some purpose and at the same time can be used
`in combination with the seat and back unit for
`a different purpose.
`Other objects of the invention may appear in
`the following speci?cation describing my inven
`tion with reference to the accompanying draw
`ings illustrating a preferred embodiment of my
`invention. It is however to be understood that
`my invention is not to be limited or restricted to
`the exact construction and combination de
`scribed in the speci?cation and shown in the
`drawings, but that such changes and modi?ca
`tions can be made which fall within the scope of
`the claims appended hereto.
`In the drawings:
`Figure l is a perspective View of a straight
`chair consisting of a back and seat forming one
`unit and a low supporting unit to which the seat
`unit is removably attached.
`Figure is a sectional view of the straight chair
`shown in Figure 1, a bowl or the like being shown
`supported by the supporting unit.
`Figure 3 is a perspective view of the supporting
`unit of the straight chair shown in Figure 1.
`Figure 4 is a perspective view of a high chair
`consisting of the back and seat unit shown in
`Figures 1 and 2 and a common high kitchen stool.
`Figure 5 is a sectional View taken on line E—5
`of Figure 4 showing the manner in which the
`tray is removably fastened to the arms of the
`chair.
`Figure 6 is a perspective view showing the back
`and seat being attached to a swing.
`Figure 7 is a top View of the seat unit after re
`moval of the cushion, and
`Figure 8 is a frame of a rocker chair adapted
`to removabiy receive and support the back and
`seat unit shown in Figures 1 and 4..
`The chair construction according to my in
`vention has a unit it consisting of a back H, a
`seat board 25, two side arms l3, and an up
`holstered seat it covered by material it adapted

`ment bar 36 thereon. Said bar is provided with
`a plurality of semi-circular notches 31 adapted to
`selectively engage the top brace rod 32 between
`the front legs to secure the foot rest in adjusted
`position. In each side edge of the top board 33
`of the stool 39 a knob 28 is fastened adapted to
`engage the corresponding eye slot 18 of the unit
`10, when the same is used in connection with the
`stool. The top board 33 has the same outside di
`mensions as the seat board 25.
`A tray 39 may be used in connection with the
`high chair formed by the units it] and 30. This
`tray will rest on the arms 19 and is removably
`fastened thereon by means of holding clamps 49
`engaging the top of the tray and the transverse .
`slots 29 in the under side of the arms l3.
`In Figure 6 a swing unit 91 is shown having
`two ropes 42 or the like supported by rings 43. A
`swing board 44 is fastened to the ends of the ropes
`42 in any convenient manner. This board is just
`as wide as the seat board [2 of the unit it and
`has on the center part of its side edges two knobs
`45 adapted to engage the eye slots [8 when the
`unit 10 is used in connection with the swing
`unit 4 l .
`In Figure 8 a low support frame 4'6 is shown
`resting on four legs 41 which in turn are fas
`tened onto rockers 46. The support frame 46
`has the same dimensions as the seat board 25
`and is provided with two holes 49 adapted to re
`ceive the pegs 21 on the seat board 25. On the
`side members of the frame 416 two knobs 28 are
`fastened adapted to engage the eye slots la in the
`straps H of the back and seat unit [0. When
`35
`this unit is placed on the support frame 96 and is
`secured thereon by the pegs 21 and the straps H‘
`a comfortable rocking chair is obtained.
`The back and seat unit 10 can be easily and
`readily attached to the rocker frame 46 and this
`can also be done without the use of any tool.
`From the above description it is clear to see
`that the low support frame 19 by itself serves the
`purpose of a commode for children. By attach
`ing the unit (9 thereto a comfortable straight
`chair is obtained and this can be effected without
`the use of any tools.
`The kitchen stool and ladder 30 can be easily
`and quickly converted into a high chair by com—
`bining the unit it) therewith, and this can also be
`done readily and without the use of any tools.
`The swing unit 9! can be used by older chil
`dren, but when a baby is to be put onto it, the
`easy attachment of unit is thereto converts the
`swing it! to a safe and comfortable swing for this
`purpose.
