No. 628,333 Int. Cl. A47k 11/02, 13/06, 13/26 US. Cl. 4134 12 Claims ABSTRACT OF THE DISCLOSURE A chair which comprises a frame and a seat of plastic material including connecting means for resiliently and releasibly engaging the plastic seat to the frame. The connecting means are included in the seat and are formed of plastic material.

The present invention relates to baby chairs, in general, and to baby chairs at least partly of a material which can be easily cleaned, in particular.

Previous baby chairs have used metal hinge members and have not had a readily removable seat and tray which may be detachably secured to the chair when desired for use, and readily removed for complete cleaning and storage when desired.

It is, therefore, one object of the present invention to provide a baby chair with means for detachably securing a tray and seat portions which may, respectively, be releasably mounted and removed for cleaning or any other suitable purposes.

It is another object of the present invention toprovide a baby chair with detachable seat and tray, respectively, which are securely and releasably mounted to a frame of the chair in a novel and advantageous manner.

It is still another object of the present invention to provide a chair having a detachable tray and seat, respectively, in accordance with the above-mentioned objectives, wherein the tray and seat are not made of metal parts, but entirely made of plastic for ready cleaning and wherein connecting means for releasably securing the seat and tray to the frame also are made of resilient plastic, and are readily cleaned, do not wear with use, and which provide excellent and secure, releasable attachment of the tray and seat to the frame.

It is yet another object of the present invention to provide a chair in accordance with the above-mentioned objective, wherein the connecting means comprises a substantially hollow cylindrical sleeve having resilient walls and an opening therein. A peg means is provided secured to the frame and the inner diameter of the resilient walls and the opening are smaller than that of the peg means for receiving the peg means therein in releasable snapping engagement.

It is yet another object of the present invention to provide a chair with detachable seat portion in accordance with the above-mentioned objectives, further comprising plastic support strips releasably attached to the bottom of the seat for supporting a bowl. The strips are releasably connected to the bottom of the seat in accordance with the present invention by resilient strip connecting means secured in part to each end of the support strips and secured in part to the bottom of the plastic seat. The strip connecting means is made entirely of plastic providing secured attachment and ready detachment of the support strips for cleaning.

It is yet still another object of the present invention to provide a chair in accordance with the above-mentioned objectives further comprising a plastic tray, and tray connecting means and attached to the tray and removable in part therefrom. The tray connecting means releasably ice engages the plastic tray to the frame and is fully washable along with the partly detachable tray connecting means.

With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawing, in which:

FIG. 2 is a bottom perspective view of the seat;

FIG. 3 is a bottom perspective view of the tray;

FIG. 4 is a perspective view of the'frame of the baby chair of FIG. 1 in collapsed position;

FIG. 5 is a bottom plan view of the seat with support strips attached thereto;

FIG. 6 is a section along the lines 6-6 of FIG. 5;

FIG. 7 is an enlarged section along the lines 77 of FIG. 5;

FIG. 8 is a front elevation of the frame of the baby chair with seat and tray attached thereto;

FIG. 9 is a section along the lines 99 of FIG. 8, and

FIG. 10 is a section along the lines 10 10 of FIG. 9.

Referring now to the drawings, and more particularly to FIGS. 14, a baby chair designed in accordance with the present invention is disclosed, comprising a collapsible frame 1, preferably made of lacquered beech Wood or the like, to which may be releasably attached thereto a tray 2 and a seat 3, the tray and the seat preferably made of plastic, such as washable nontoxic Moplen, or the like.

The frame 1 comprises four supporting legs to which a lower front board 5 is rigidly mounted in slots 6 between front supporting

legs

4a and 4b, and to which an upper back rest board 7 is rigidly mounted in slots 8 between rear supporting

legs

40 and 4d.

An upper and lower

transverse side bar

9 and 19, respectively, are pivotally connected by screws or other pivot means 9a and 10a, respectively, at their ends to and between each of the front and rear supporting legs ib-4d, and 4a-4c, respectively, at the outer sides thereof, forming collapsible parallelograms with the supporting legs and permitting the frame 1 to collapse into the position as shown in FIG. 4. Conventional metal locking braces 11 are pivotally connected diagonally to each of the rear supporting legs and the corresponding lower side bars 4d10, and 40-10, respectively, and are conventionally joined pivotally to each other for securing the chair in open position (FIG. 1) and for permitting expeditious closing of the chair when desired to the closed position (FIG. 4).

Referring now again to the drawings, and more particularly, to FIGS. 2, 4, 5, 6 and 9, the seat 3 is formed with a rear hollow portion 12 having an inverted U- shaped cross-section (FIG. 9) and having vertically elongated slots 13 (FIG. 2) along sides 12:: of the rear hol- 10w portion 12. As described relative the connected position of the seat 3 to the frame 1, the upper end of the rear hollow portion 12 adjacent the slots 13 (FIG. 6, being shown inverted from the connected position) contains substantially cylindrical sleeve formations 14 tangentially secured horizontally at the upper portion of outer peripheral walls 14a thereof to the interior wall 12b forming the hollow portion 12 at the apex thereof. The outer peripheral walls 14a of the cylindrical sleeve formations 14 are somewhat smaller in radius than that of the interior wall 12b of the rear hollow portion 12, and accordingly the cylindrical sleeve formations 14 are disposed in spaced relationship at the sides thereof from the interior wall 12b forming the rear hollow portion 12, as shown in FIGS. 5 and 9.

The cylindrical sleeve formations 14 each have an open end 15 terminating at the upper end of the slots 13. An-

other opening or slot 16 is formed along the length of and in the bottom of the cylindrical sleeve formations 14, the slot 16 having a width slightly less than half the diameter of the cylindrical sleeve, thereby permitting wooden pegs 17 horizontally aligned and secured to the inwardly facing sides of the rear supporting

legs

40 and 4d, respectively, to be vertically inserted into the interior of the cylindrical sleeve formations 14 through the openings 16-. In this manner the rear of the seat 3 may be snappingly and detachably secured to the frame 1 of the chair via the pegs 17.

The inner diameter of the cylindrical sleeve formations 14 is slightly smaller than the outer diameter of the wooden pegs 17; the cylindrical sleeve formations 14 are preferably made of plastic and are resilient and spaced from the interior wall 12b forming the hollow portion 12; and the openings 16 are slightly smaller than the diameter of the pegs 17. Accordingly the sleeve formations 14, when pressed downwardly onto the wooden pegs 17, resiliently expand along with the openings 16 to engage the wooden pegs 17 therein securely but in releasable fashion. The cylindrical sleeve formations 14 are also formed with a circular end wall 18 at the interior ends and spaced from the open end a distance substantially equal to the length of the wooden peg 17, to provide resilient strength to the sleeve formations 14 for engaging the wooden pegs 17.

The top side of the front of the seat 3 is curved smoothly downwardly and extends somewhat over the upper top edge 5a of the lower front board 5. The bottom of the front of the seat 3 is provided with abutments 19 which rest on the upper top edge 5a of the lower front board 5, maintaining the seat 3 in horizontal position.

The rear snap-in connection described permits pivotable movement of the seat 3 for convenience when desired, the seat merely resting by the abutments 19 on the front board 5. The weight of the child sufficiently maintains the seat 3 against the upper top edge 5a of the front board 5, while the rear of the seat 3 is pivotally and securely connected, preventing backward movement or forward sliding of the seat.

Referring now again to the drawings, and more particularly to FIGS. 2, 5, 7 and 9, the seat 3 is formed with an enlarged central opening 20. Under the seat 3 adjacent each lateral side of the opening 20 are two hol- 4 low, substantially cylindrical projections 21 depending from the bottom of the seat 3, which are preferably made of plastic or the like.

Support strip 22, having mating male projections 23 (FIG. 7) extending therefrom adjacent each end, are adapted to be releasably engaged in the hollow cylindrical projections 21, thereby supporting the support strips 22 in spaced relationship from the bottom of the seat 3 (FIG. 9) and laterally alongside the opening 20 of the seat 3 (FIG. 5). In the engaged position of the support strips 22 (FIG. 7), being shown in inverted position (from the engaged position) arcuately shaped, inwardly facing contours 24 (FIG. 5) of the support strips 22 receive and hold a removable bowl 25, indicated in dashed lines, by flanged bowl edges 26. The two forwardmost hollow cylindrical projections 21 of the seat 3 are spaced slightly closer together than the rear projections (FIG. 5) permitting the bowl 25 to be readily slid onto and off the support strips 22 from the rear.

Referring now again to the drawings, and more particularly to FIG. 7, the male projections 23 define an outer wall 23a and an extreme end 27. The outer diameter of the extreme ends 27 of the male projections 23 of the support strip 22 are slightly wider than that of the remainder of the male projections 23. Adjacent to remote or lower ends 28 of each hollow cylindrical projection 21, inner wall 21a of the hollow cylindrical projection 21 has a narrowed portion 28a having a slightly smaller diameter than that of the outer diameter of the extreme ends 27 of the male projections 23 and also smaller than the inner diameter of the remanider of the hollow cylindrical projection 21. When the male projections 23 are pressed into the hollow cylindrical projections 21, the narrowed portions 28a of the hollow cylindrical projections 21 resiliently expand to receive the enlarged ends 27 of the male projections 23 therein. As each entire male projection 23 is inserted within the hollow cylindrical projection 21, the inner wall 21a of the hollow cylindrical projection snugly and resiliently contracts to accommodate and securely hold in releasable engagement therein the male projection 23. The support strips 22, and the connecting

projections

21 and 23, respectively, are made of plastic, and may be readily washed when removed.

Referring now again to the drawings, and more particularly to FIGS. 1, 3 and 8-10, the bottom of tray 2 is illustrated having two forward fiat abutment extensions 29 which are complementary to, and which rest against and in front of, the upper ends of the

front supporting legs

4a and 4b, respectively, when the tray 2 is positioned so as to rest on the upper side bars 9, thereby preventing rearward movement of the tray. The underside of the tray 2 is formed with parallel support abutments 39 so that the tray 2 is maintained horizontally on the side bars 9.

Outer side edges 30 of the front abutment extensions 29 rest snugly against inner side faces 31 of the upper side bars 9, the upper side bars 9 extending slightly forward of the front supporting legs 4a and 411, respectively.

Swingable latches 32 are horizontally pivotally connected to the bottom of the tray 2 by hollow cylindrical projections 33, depending downwardly from the bottom of the tray 2 adjacent outside faces 34 of the upper side bars 9. The hollow cylindrical projections 33 terminate substantially adjacent bottom faces 35 of the upper bars '9. The hollow cylindrical projections 33 are preferably made of plastic or the like and are similar in construction to the projections 21, described hereinbefore for holding the support strips 22.

The swingable latches 32 are also formed preferably of plastic having male projections 36 {similar to male projections 23) at one end thereof for engagement with the hollow cylindrical projections 33. Once engaged in the hollow cylindrical projections 33, the male projections 36 are pivotal therein providing for horizontal pivotal movement of the latches 32 in the hollow cylindrical projections 33 relative to the bottom of the tray 2. Each latch 32 includes an extending horizontal portion 37, which, when the latch 32 is horizontally pivoted from the open position (as illustrated at the right-hand side of FIG. 8) to the closed position (as illustrated at the lefthand side of FIG. 8), the horizontal portion 37 of the latch 32 passes snugly against the bottom face 35 of the upper horizontal side bars 9 for securing the tray 2 to the frame 1 and preventing lifting of the tray 2 off the side bars 9 of the frame 1. The latches 32 are swung all the way to abut against the rear face 38 of the front supporting

legs

4a and 4b, respectively, to prevent forward movement of the tray 2, relative to frame 1, thereby completely securing, releasably, the tray 2 in position to the frame 1.

The hollow cylindrical projections 33, which resiliently engage the male projections 36 in accordance with the present invention, provide sufficiently rigid attachment, so that the tray 2 is secured against forward and lifting attempts by the child. Furthermore, all parts of the tray 2 including he connecting means, namely, the abutment extensions 29, the

projections

33 and 36, and the latch 32, may easily be removed and cleaned.

It is readily apparent that the chair of the present invention has excellent features providing for entirely plastic casting manufacture of trays and seats including connections which may be removably detached, and readily secured to the frame of the chair and which may be dis connected for washing of all parts.

The connections being plastic are formed in a manner to resiliently expand and to secure the tray and seat, respectively, to the frame with exceptional strength and yet which may be readily detached with ease.

The support strips 22 for holding the bowl are also easily removable, as well as the latches 32 for the tray 2 and may also be cleaned separately without damage.

It is apparent that with the present invention all portions of the chair which are easily soiled are formed of plastic or similar material and are removable for easy cleaning, which heretofore was impossible with metal hinges.
