Description

Feb. 5, 1963 P. c, SMITH ETAL BABY SEAT Filed May 16, 1960 ArrQPA/Z'KSZ United States This invention relates to an infant chair or jumper.

It is an object of this invention to provide a device in which a child may sit which will yield up and down to permit an infant to experience the sensation of jumping up and down while the seat moves with him.

It is a further object of this invention to provide such a device wherein the spring pressure may be varied to accommodate varying size children.

It is still a further object of this invention to provide means for varying the height of the seat when variations are made for the weight thereof.

Still a further object of this invention is to provide means for maintaining the seat horizontal at all times.

Still a further object of this invention is to provide a device which may readily be folded into a compact package for storage or conveyance.

Other objects and advantages will be readily apparent from the following description.

In the drawings:

FIGURE 1 is a side elevation of a device embodying this invention.

FlZGURE 2 is a side elevation of the device in the folded position.

A U-shaped base is provided having plastic clips 12 thereon to provide additional friction against sliding. Each end 14 of the base is bent upwardly and at the extrernities a bar 16 is pivotally connected to the base frame as by pin 18.

A seat frame 20 is generally U-shaped and has its extremities 22 bent to project rearwardly and downwardly. Suspended from frame 20 by cloth 24 is seat 26. A backrest 28 is pivotally mounted between brackets 30 mounted upon extremities 22 of frame 20.

The backrest has a pair of

pins

32 and 34 the former of which rides in slot 36 and the latter of which is positioned in one of the notches 38 in bracket 30 to permit the backrest to be pivoted with respect to the seat 26.

The upper extremity of each bar 16 is pivotally connected as by a pin 40 to arm rest frame 20". j

A reinforcing frame 42 is generally U-shaped and is pivotally connected by pins 44 to frame 20 and by pin 46 to frame 10 at a position spaced from bars 16 and formatet ice ing a parallelogram with the upturned end '14 of base frame 10 and a portion of arm rest frame 20.

This construction insures that seat 26 will be suspended in a plane parallel to base 10* as the seat is raised or lowered. A spring 48 is secured at each extremity of seat frame 20 and the spring is secured by a loop 50 to bar 16. A series of protuberances 52 being provided over which the loop may be trained to vary the spring tension.

In FIGURE 1 the loop 50 is over the uppermost protuberance whereby the spring is at minimum tension to accommodate a smaller child. In this position the at-rest position of the seat is also at its lowest position to accommodate a smaller child. As the loop 50 is positioned over a lower protuberance 5-2 the spring tension is increased to accommodate a larger child jumping up and down therein and the at-rest position of the seat is raised to accommodate such larger child.

When it is desired to fold the device loops 50 are disengaged from protuberances 52 permitting frame 42 to pivot towards frame 10 until same contact. Backrest 28 is pivoted to the foremost position thereby forming a compact package suitable for storage or transportation and lending itself readily to packaging.

While what hereinbefore has been described as the preferred embodiment of this invention, it is readily apparent that alterations and modifications may be resorted to without departing from the scope of this invention and such alterations and modifications are intended to be included within the scope of the appended claims.

We claim:

An infants seat comprising a U-shaped base frame, an upwardly projecting bar pivotally attached at each extremity of said base, a U-shaped seat frame having downwardly bent extremities pivotally secured to said bars, a seat carried by said seat frame, a further U-shaped frame having its extremities pivotally attached to said base frame, said further frame being pivotally attached to each extremity of said seat frame so as to remain substantially parallel to said bars, a spring secured to each extremity of said seat frame, a series of protuberances on said bars, a loop on each spring adopted to selectively engage one of said protuberances.
