BABY JUMPER Thomas H; Mekeel and Leland I. Cammack, -.San Jose, Calif.

Application April-16, 1956, Serial N0. 578,250

'7 Claims. r (Cl.-1 55--18) This invention relates to a so-calledbaby jumper which isadapted for use'by comparatively-young children.

"Jumpers of1 the-character described-'arewknown in the art, and comprise -a seat frame for supportinga baby seat at one end,-being pivotally;mounted for rocking movement .intermediate its ends, -=and held by resilient means at the opposite end so that the baby' may amuse 'himself by rocking the seatframeagainsta the-action of -the resilient means.

Summarizing this-invention; it has as its objects, among others, the provision of an improved jumperof the character described 7 which is composed of :few "and simple parts, thus making for economy of: manufacture; is portable 'and collapsible whereby it can *befolded'into a compact space 1 wherein all 'the: parts lie in substantially the same plane, thus facilitating storage and;handling,

and which is of such construction enabling the babyseat .to be readily removed for cleaningand replacement after the parts vwith the jumper'in collapsed statepportions of the structure being brokenaway to disclose: the construction more clearly.

The jumper comprises a .base frame 2 desirably. of

generally rectangular shapeIand-formed ofilight metal tubing, to thus provide an open frame construction. Pivotally'connected-at 3 to side members .4 of the base2 area pair of support members-6; such support members "being connected'to the baseframe adjacent the front end thereof a littleless-than a; third ofthe-lengthof such base frame. Mounted for detachable. pivotal movement on support members 6 is a generally U-shaped-baby seat frame 7 closedat oneend -8. and open at the opposite end -9; the side legs .11 of such-seat frame being displaced inwardlyfrom-adjacent the open end of-the seat frame for a purpose to be later described. Frame 7 is desirably of light tubing.

For providing such detachable pivotaluconnectionof the seat frame, a support rod 12 having a head 13 (Fig. 4) at one end passes through apertures 14 in the upper end of support members 6 and through apertures 16 in legs 11 of the seat frame. When the seat frame is mounted on: the support members.6, a..wing nut 17 screwed on rod .12 opposite. tothe-head-end 13, holds the entire assembly together.

At the-same-timegseat' frame7 can rock or pivot-about-rod12-in the upright-position of support members 6.

1 larger diameter.

end at a-point about. one-fourth the length of such seat frame.

For holding support members 6 in an upright position and. the seat frame 7 in an elevated position, strut means 18 is connectable between such support members 6and base 2; the strut means extendingrearwardly from the support members to base 2. Such strut means may bear pair of relatively stiff rod members detachably connectable to the described parts when the seat frame is erected. However, in the-embodiment illustrated, each strut means comprises a link 19 pivotally connected to an upright support member 6'and also pivotally connected-at 20 to another link 21,.in turn pivotally connected to base2.

.Each linleZl has apin22 adapted to engage in a:slot 23 intthe associatedlink .19 in the set up position of the seat frame.

A special type of. baby seat 26 is removably mounted on theclosed end 8 of seat frame -7. This seat is desirably formed of any suitable strong flexible and washable material, such as plastic or cloth and at its upper endis provided with a looped portion 27 formed by a hem. Desirably, an apron portion 28 is provided to extend upwardly from the bottom of the seat. Looped portion 27 readily permits the seat to be removed from the open end of the-seat frame for cleaning or washing,

and also .tobe readily replaced.

Because of the open end 9 of the seat frame which permits ready removal and replacement of baby seat 26,

its..legs ll have a springeifect; anddetachable spacer meansis provided betweenlegs 11 of the seatframe .to hold such legs in position when wing nut 17 isv tight- .pair of spacer rods 32 mounted similarly to spacer rod .31. Spacer rods 32 are adapted to pass through-looped portions 33 formed by hems in the apronportion 23 of the seat, which includes an apronextension 34 to provide a shelf in which the baby may place toys or the like.

Rods 32 can be removed and replaced in the same man- ..ner as rod 31.

With reference to Fig. 4, it will be noted that the inward. displacement of the'seat frame legs 11 provides a space between each leg 11 and a base frame side member 4 in the collapsed position of the jumper, to thus accom- -n1o'date support member 6 within such space in the colfQrJdetachabIe connection between the front end. ofthe seat sframe opposite the babyseat and the frontend of the base-frame. Such resilient means comprises coil spring means 36. having an eye'3'7 at. its upper end connectedsover a bowed portion 33 on front spacer rod. 31, and a hook 39 at its lower end detachably connectable in an. aperture or similar attaching means. on the front end of base 2. Desirably, the coil spring means 36 is formed of coil spring sections of different diameters with section 41 of lesser diameter screwed into section 42 of Such arrangementprovides. means. for adjusting tension of the spring in accordance with the weight of the baby.

In collapsing the jumper, this can be readily done by unhooking hook 39 of spring means 36, and turning sup port members 6 in one direction rearwardly as indicated by the direction arrow D in Fig. 3, and simultaneously turning seat frame 7 in an opposite direction forwardly as indicated by direction arrow D. This enables the jumper to be collapsed with the seat frame lying Within the open area of the base frame and substantially in the same plane thereof, so that it can be very readily transported. Setting up of the jumper can be readily accomplished in a reverse manner.

When the jumper is set up, it will be noted that the length of seat frame 7 is such that it does not substantially overhang the ends of base frame 2 and the sides of the seat frame are located between the sides of the base frame. This, in cooperation with the rectangular shape of the base frame, provides for great stability in use. Only one element, namely wing nut 17, need be unscrewed when it is desired to remove seat 26 for cleaning. Hence, disassembly of the seat frame can be quickly effected. When the wing nut is unscrewed and support rod 12 pulled out,

rods

31 and 32 are readily removed from legs 11 of the seat frame. Rods 32 can be quickly removed from seat 26 by sliding them out of loops 33 formed in the apron portion 28, and the seat can be quickly removed by sliding it off either of legs 11. Since only one wing nut 17 holds the entire seat frame assembly together, reattachment of the parts can be quickly and easily effected.
