BABY CHAIR Filed Nov. 12, 1959 INV EN TOR. [4
United States Patent 3,017,220 p BABY CHAIR Victor A; Chernivsky, 4349 Downers Drive, Downers Grove, Ill. Filed Nov. 12, 1959, Ser. No. 852,527 10' Claims. (Cl. 297-'-390) This invention relates in general to a baby support in the form of a collapsible chair having an inclined back, a supporting seat and particularly adapted for use'on an automobile seat as well as upon a flat surface.
An important object of the invention is to provide resilient wire chair frame comprising separable but interengaging base and back rest portions which may be disengaged for compactly packaging the chair, the portions being composed of spring materials with tubular means for connecting them, to firmly hold the parts together when they are assembled.
A' further object of the invention is to provide a foldable chair having an inclined back with a' seat rest and side arm supports;
Still' a further object of the invention is to provide a chair with a back support and a seat with side arms and a cross piece for the seat, composed of a fabric bag confined in the" back of the frame to the side arms and connected at the front to the cross piece for comfortably seating and supporting a' baby or a' small child therein.
A still further object of the invention is to provide a child chair having an inclined back rest, detachable from a supporting base, with a fabric back and seat supported by side arms and by a cross piece at the front of the seat with a crotch support connected to the cross piece for additionally holding a child in place.
A still further object of the invention is to provide side arms and a support therefor for an inclined back frame of a chair, which are joined together at the front of the chair to form a restraining cross piece.
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 accordarice with this invention with the parts in assembled position and representing the chair as supported upon a portion of an automobile seat.
FIG. 2 is a side elevation of a portion of the chair showing the connection of the side arm and its support to the back portion of the frame of the chair.
FIG. 3 is a' perspective detail showing a connection sleeve for one end of the back rest.
FIG. 4 is a view in elevation of one end of an arm or support at right angles to a sleeve and its supporting bar which it passes over; and
FIG. 5 is a side elevation of one end of a supporting bar at an angle of a' support at an angle to a connecting sleeve and its supporting bar after it has passed over the sleeve.
This baby chair has a fabric back with a seat at the bottom; the ends of the seat are supported by side arms connected to' the back rest and the arms supported by a member similai to the arms which together form a cross piece to which a crotch strap is attached for additional safety in" holding a child in a comfortable position in the chair. p
Referring now more particularly to the drawings, the chair comprises a base and a back 12 each formed of bent wire or tubulat material having corresponding terminals which are secured together by a tubular connector 14 at each side of the chair Each tubular connector has notches or dents for securing it to ea ch end of and back therein.
the back and to limit the insertion of the hd 6f the base 7 The base 10 has substantially parallel sides 18 connected by a cross piece 20 at the rear with downwardly turned connecting bends 22 for ofisetting the cross piece downwardly from the side portions so that this cross piece may be definitely engaged in' the crack or recess between the seat A and back B, for example, of an automobile (or other seat) asrep'resented in FIG; 1. The front ends of the sides 18 of the base have outwardly and downwardly bent portions 24 with reversely bent upward and rearward portions 26 which form engaging legs at their extremities upon which the" front of the base is firmly supported, the rear being supported by the cross'piece 20;
To provide additional engagement and frictional'support for the front extremities of' the base, short sleeves 28"of rubber, plastic or other material are inserted upon the outwardly extendihg' portions 24 of the base which may actually engage a seat cushion" or a flat'surface to which thechair is applied. A
The upper eXt'remitiesSll of the upwardly bent portions 26 are inclined, usually inwardly or outwardly, slightly out of line with the extremities" of the back 12 so that these extremities must be displaced or sprung slightly taen ags them with the ends of thetub'ular connectors 14 so that whenthey are pressed into engagement, the base and back portions of the chair frame are held fric tionally' and tightly together against accidental dislodgement. By turning the portions 24 outwardly, the front legs are space'd'fu'rther apart increasing the stability of the chair upon any supporting, surface.
The upper portion of the back rest 12 is rounded to receive a cover 32, the upper end of which is doubled to form a p'oucheatendi'n g over the rounded ends of the back and conforming thereto. At the lower end of the cover is a seat section 34s'ecured thereto substantially at right angles by stitching or otherwise, the seat section being curved to conform to the body and having side portions terminating in' arm grips ss which may be fastened together by snap buttons 38 like glove fasteners or other similar connections. I
In order to support the seat section, a pair of U-shaped members, one forming an arm rest 40 and another forming an arm support 42 are loosely connected to the lower end of the back 12 before the base 10 is attached thereto.
Each of the arm members 40 and 42 is formed at both ends with aloop 44 embracing more than a full turn of the material and having a button 46 engaging the end, formed of rubber and other similar material and adapted to cover the sharp edges of the cut end of the member which. is usually made of metal, to prevent the catching and damaging of garments and the like. It also makes a neat andattra'ctive finish for the ends of these members.
Each of the loops 44 has an inner diameter sufiicient "t6" slip freely over the sleeves or tubular connections 14 when the connecting portion of the member (40 or 42) is at right angles" to the sleeve as represented in FIG. 4, butfits tightly about the metal bar of which the back 12 is constructed when one of the members is inclined to' the bar and to these connectors 14 so that it will not slip over the connector and also will be engaged in a bend of the side bar since the member is not at right angles to the bar at this point.
In order to provide a suitable engagement for the loop ends of the arm rest4ll, the back 12 is formed with opposite bends 48 and 50 intermediate the top and bottom of the back forming an angularoifset portion 52. This will incline the upper portion of the back usually at about thesame angle as th'e inclination of the lower portion of the back 12 with respect to the bent upper eitrern ics 30 of the base, but the inclination of the upper end of back may be slightly more or less depending to accommodate the occupant of the chair in a reclining position. The inclination of the upper portion" of the chair is such that it will substantially engage the average back B of an automobile or other seat to which the chair is applied and affords more comfort to a child sitting in the chair.
The arm rest 40 and support 42 are preferably made of the same dimensions so that they may be identical, thus reducing the number of different parts of the chair and when two of them were applied in the manner described to the lower end of a back 12, the loops 44 of the arm rest 40 will be engaged by the lower bend 48 of the back 12 and the similar loops of the arm support 42 will be engaged by the upper ends of the tubular connectors 14. The arm grips 36 are extended over the tops of the arm rests 40 and the grips are held in place by the snap buttons 38.
The two connecting portions of the arm rest 40 and the arm support 42 extend in front of the seat section 34 of the cover, they are coextensive in length and are secured together by a front hand grip 54 which may be wrapped about these adjacent portions of the members, but preferably the connector forming the hand grip is a spiral wrapping of cane, fiber, or plastic material which is easily applied thereto by threading it from one end of the hand grip portion and preferably covers the full length thereof. It provides a convenient and suitable hand grip for the occupant of the chair and also it encloses the seat portion of the chair and secures the said I arm members together in a fixed angular relation which insures the proper support of the arm rests when the chair is in use.
To additionally support the seat at the middle of the front edge thereof, a crotch strap 56 is secured by stitching or any other suitable manner to the under side of the seat section 34 and is of sufficient length to extend upwardly and over the front hand grip 54 centrally thereof so that the legs of a child sitting in the seat may extend from the seat on both sides of the strap. This strap is preferably looped over the hand grip and has a snap button or a similar connecting device for attaching the upper end of the strap in the loop position.
With this construction, a chair may be packaged and shipped in partially knock-down position with the base and back separated at the tubular connectors 14 so that the parts may be assembled in more compact relation. The cover may be applied to the back and the arm rest and arm support may be connected together in the completely assembled form so that it is necessary only to attach the base to the back by springing the extremities 30 into tight frictional engagement with the open ends of the tubular connectors 14.
As thus set up, the chair is ready for use either on a plane or fiat surface or with the oifset cross piece 20, engaging in a notch between the back and seat cushion of an automobile or other upholstered seat. Thus a baby or small child may be taken without removal from this chair into an automobile or any other different location without disconnecting any of the chair parts.
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.
