I CHAIR CONSTRUCTION Filed Jan. 22, 1946 2 Sheets-Sheet 1 :KEENE LUTES I I v Nov. 21, 1950 K. LUTES CHAIR CONSTRUCTION 2 Sheets-Sheet 2 Filed Jan. 22, 1946 Zlvwtwvtc'n KEENE LUTES Patentecl Nov. 21, 1950 UNITED STATES PATENT OFFICE 3 Claims.
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 specification describing my invention with reference to the accompanying drawings 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 described in the specification and shown in the drawings, but that such changes and modifications 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 E5 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 invention has a unit it consisting of a back H, a seat board 25, two side arms l3, and an upholstered seat it covered by material it adapted 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 provided 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 accidental 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 i.
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 forming 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 Figure 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 having a circumferential flange 22 adapted to support 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 dimensions 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-embodying 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 substantially 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 surface 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 adjustment 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 dimensions 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 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 fastened onto rockers 46. The support frame 46 has the same dimensions as the seat board and is provided with two holes 49 adapted to receive the pegs 21 on the seat board 25. On the side members of the frame 16 two knobs 28 are fastened adapted to engage the eye slots la in the straps H of the back and seat unit [0. When this unit is placed on the support frame 96 and is secured thereon by the pegs 21 and the straps H a comfortable rockin 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 attaching 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 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 children, but when a baby is to be put onto it, the easy attachment of unit is thereto converts the swing t! to a safe and comfortable swing for this purpose.
