ThisV invention relatesto infants chairs, and more Yparticularlyv to an -infan-ts chairI of theficol-f lapsible type.

Almain object offth-e invention is to provide a novel and improved collapsible nursery chair Which-isvvery simple in structure, easy to fold, and read-ily carried-from place to place.

Aifurther object ofthe invention is to provide an improvednurserychair ofthe folding type, saidl chairbeing inexpensive to manufacture, very 'compaetiinsizef when folded, light in weight, and readilyA set -up for use.-

F-urther. objects and advantagesof the vinvention .will become apparent from the following description and' claims, and from the. accompanying drawings,v wherein:

Figure 6 is an enlarged detail view, partly in cross-section, showing theYhinge-fmeans for the supporting -legelementsof-the'chair of Figure 1.

' Referri-ngto the drawings, II, designates. the base portion of the seat, said base portion being generally rectangular in shape and having raised side ribs I2, I2. Each side edge of base II is notched adjacent its front and rear portions, as shown at I3 and I4 the notches traversing the ribs, and received in the notches are the respective vertical elements I5 and I6 of side supports I'I, the vertical elements I3 and I4 being pivotally secured to the ribs I2, I2 by pins I8 extending longitudinally of the ribs and traversing the upper portions of the notches I3 and I4, whereby the side supports may be pivoted around the pins when the chair is to be folded. Each side support has an upper horizontal arm rest bar portion I9. Pivotally secured to one of said upper horizontal bar portions is a tray member 20, said tray member being formed at its bottom surface adjacent its free edge with a groove 2I adapted to receive the opposite upper bar portion to lock the side supports in vertical positions. A ilexible fastening strap 22 is secured to the under surface of tray 20 at its mid-portion adjacent its forward edge. The lower end of strap 22 is de- 2. tachablyfsecuredto theibottom surface. of `base pottion :I I :adjacentits forward edgelby `aiconventional snap fasteneaZS.

In this position, the chair is substantially flat and may be easily carried from place to place.

To unfold the chair, the side supports are swung to vertical positions, back support 29 is swung upwardly into engagement with stop pins 30, tray 20 is rotated to a position wherein groove 2I receives the top bar I9 adjacent thev free end of the tray and strap 22 is secured to the bottom of base portion I I.

For conveniences in carrying infant accessories, a pocket or pouch 3l of flexible material is provided at the rear surface of back support 2S, said pouch having a closure flap 32. y

While a specific embodiment of a nursery chair has been disclosed in the foregoing description, it will beunderstood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention other than as defined by the scope of the appended claims.
