Nov. 12, 1963 H v. A. CHERNIVSKY BABY CHAIR Filed June 19, 1961 INVENTOR: W0 70/? A. CHE/PN/ VSK Y ATT 'Y United States Patent 3,110,519 BABY CHAIR Victor A. Chernivsky, 4349 Downers Drive, Downers Grove, Ill. Filed June 19, 1961, Ser. No. 118,168 Claims. (Cl. 297285) This invention relates in general to a baby chair having a back with a separate cover therefor having a back with an inclination therein and a cover separately applied thereto and a base for supporting the back.
An important object of the invention is to provide a. marginal wire frame comprising separable but interengaging resilient base and back portions, the back of which has a separate bend therein, and the portions being composed of spring materials with connecting tubular means for firmly holding the parts together when they are assembled.
A further object of the invention is to provide a fabric bag which may be slipped upon the back frame or section with a dip in the fabric conforming to the back inclination to form a more comfortable seat.
A still further object of the invention is to provide an easily sewn fabric cover composed of fitted pieces which may be applied to the separately inclined back after they are connected for additionally completing the seat and forming a depression into which the body of a child may fit more readily.
Other objects of the invention will appear in the specification and will be more apparent from the accompanying drawings in which,
FIG. 1 is a perspective view of a baby chair in accordance with this invention with the parts of their assembled position.
FIG. 2 is a perspective view of the flexible back marginal frame as shown in FIG. 1.
FIG. 3 is a composite view showing the shape of the several sections of fabric which are attached together to form a cover; and FIG. 4 is a perspective composite view of separate pouch, seat and back sections to form a cover in accordance with this invention with a seating depression at the bottom of the bend in the back, as in FIG. 1.
Tbs baby chair has a fabric back composed of three shaped sections which are attached by preferably sewing them together forming side engaging portions and an upper pouch into which the back may be inserted from the lower connection end of the back.
Referring now more particularly to the drawings, a marginal wire frame forming a back has substantially parallel sides and ends 12 with parallel angular bends 14 nearer the lower end thereof and a rounded top 16.
The ends of the back are preferably fitted with hollow sockets 18 for engaging corresponding extremities 20* of a supporting base 22 which has outward and downward bends 24 forming front feet and a downwardly turned connector 26 at the back forming a third support for the marginal base, thus adapting it to be positioned upon any surface even in the seat of an automobile if desired. The ends 20 of the base may be sprung inwardly into engagement with the sockets '18 to connect the back and base portions of the frame together.
A cover comprising three shaped pieces 28, 30 and 32 is assembled by sewing them together at the sides and around the upper end to fit over the separately inclined back. The parts are preferably composed of canvas or other stout fabric but may also be made of other materials. 'Ihe middle piece 30 has an upper edge 34 engaged to fit the upper edge 36 of the first piece 28. They are stitched or otherwise secured together from the under side so that the stitching is turned inwardly at the top of the cover.
The lower edge 38 of the middle piece is also rounded Patented Nov. 12, 1963 and the third piece 32 has an upper straight edge 40 of which the length corresponds substantially to the arcuate length 38 of the middle piece and the opposite smaller edge 42 is substantially of a length to fit across the ends 12. These two edges '38 and 40 are turned rearwardly and stitched together at the back of the two fabrics forming an angular dip or depression 44 as shown in FIG. 1 when secured to the frame.
At the sides of the central member are shouldered portions 46 which engage extremities 48 of the longer edge 40 of the piece 32 and the sides of the pieces 30 and 32 are formed with parallel side stitches 50 which form tubular sockets extending along the sides of the cover into which the parallel sides and ends 12 of each cover are inserted when the cover is finished. In operation, a cover thus made is inserted over the parallel ends of the back 10 leaving the upper pouch loose until the upper parallel sides of the cover reach a point where the upper pouch piece v28 may be turned over the curved back of the rest 10. There is sufficient slack to permit this movement and to permit the lower edge of the cover to extend around the socket 18, leaving the ends clear for the insertion and attacheent of the ends 20 of the base At the lower extremities of the piece 32 are angular corners 52 which are folded over and are seamed to form the sleeve substantially at right angles to inclined ends 54 of this piece, thereby making a smooth cover at the bottom to which a decorative and also a strengthening and retaining tape 56 may be applied, usually of contrasting color forming a decoration and finish to the rest of the cover.
With this construction the back 10 and the base 22 may be more compactly stored and packaged before assembly. The cover is applied to the back before it is attached to the base by inserting the parallel ends from the top downwardly into the sleeves formed by the side stitching 50 with the exception of the attached top piece 28 which is left loose until the rounded connecting portion is reached whereupon the top pouch formed by the piece 28 is stretched over the connecting rounded end 1-6 of the back rest. The cover is then moved downwardly if necessary, until the dip or depression '44 registers with the angular bend 14 at which time the lower end of the cover will preferably extend partially over the sleeve con nectors .18 at the lower ends of the back rest. In this condition, the base is applied to the back rest by springing the ends 20 of the base into the sleeve members 18 and inserting them a short distance to engage with the sleeves so that the back will be supported by the base with the cover in a definitely angular position forming a pouch or depression at the rear into which a child is seated most securely and comfortably. The cover is sufliciently loose so that the seat 32 will give slightly and the arms of an occupant of a chair rest naturally and comfortably on the lower inclined portions 12, the back at the same time extending upwardly and holding the occupant in a pleasant upright position.
While a preferred form of the invention is shown in some detail, it should be regarded as an illustration or example rather than as a limitation or restriction of the invention, since various changes in the construction, combination and arrangement of the parts may be made without departing from the spirit and scope of the invention.
