13 Claims. (Cl. 155-17) in a childrens chair.

It is always desirable to provide for easy storage of the toys and the like used by children. For this reason it is desirable to provide a rocking support such as that shown in my above referred to patent which may be folded and converted into a substantially flat package which is adapted to be easily stored.

It is also desirable under some circumstances to be.

able to prevent rocking in my support so that the chair or the like may be held in a substantially steady position even though the child is seated therein. This has many obvious advantages. For one, the support can then be used as a perambulator in which a child may move himself about, or in which an adult can push the child.

It is therefore an object of this invention to provide a foldable rocking support such as described above.

It is a further object of this invention to provide a rocking support such as described above which has a steadying feature. 1

It is yet another object of this invention to provide 'a foldable rocking support which comprises a body supporting member, rigid means which are adapted to support a portion of the body supporting member, spring means which are adapted to support another portion of the body supporting member, and a collapsible frame which has the rigid means and the spring means connected thereto, the frame being adapted to support the body supporting member in a rocking position and to be folded with the body supporting member attached into a substantially'flat storage position.

It is yet another object of this invention to provide a rocking support which comp-rises a body supporting member, rigid means which are adapted to support a portion of the body supporting member, spring means which are adapted to support another portion of the body supporting member, a frame which has the rigid means and the spring means connected thereto-to support the member'i'n arocking position, and means adapted to be positioned between the body supporting member and the frame for holding the member in a substantially steady position.

Other objects and advantages of the invention will become apparent from the'followingdescription taken together with the accompanying drawings.

Of the drawings: a

Figure l is a partial perspective support of this'invention.

Figure 2 is an enlarged partial along theline 2--2 ofFig. 1-.

View of the rocking sectional view taken I Figure 3 is a partial side view of the rocking support Referring now to Figure 1, a rocking support 10 is shown therein which includes a frame member 11. The frame member 11 comprises a pair of generally U-shaped tubular

sectional portions

12 and 13 which are overlapped at 12a and 13a and are pivotally connected together by pivot pins 14 which pass through each of the U-shaped members. A strengthening member or axle 15 passes through the Ushaped member 13 and has enlarged ends 16. A locking rod 17 is pivotally posi tioned across the mouth of the U-shaped member 12 and is connected to the member near its ends 12a by means of a hook shaped end portion 17a which grips the tubular U-shaped member 12 at 17b and 170. This grip allows the rod 17 to pivot about the gripping points 17b and 17c for locking purposes which will be described later.

A foot rest 18 is mounted across the bottom portion of the U-shaped section 12. The footrest includes a kick plate 19 and a pair of wheels 20. The wheels 20 are mounted on the support rods 21 and the kick plate is mounted on the support members 22. Both the support members 22 and the support rod 21 are attached to rotatable collars 23, which are mounted on the tubular U-shaped member 12. A set screw 41 is provided in each of the collars 23 which allows locking of the foot rest in the raised or operable position shown in Fig. l. The kick plate is then adapted to support the feet of the occupant and the wheels'allowthe support to be moved with ease. By loosening the set screws 41 the foot rest 18 may be flattened for folding by rotating it so that the wheels and the kick plate are substantially aligned with the tubular U-shaped member 12.

The seat member 24 is located about in the center of the support 1 0 and includes a seat back 25 and a seat bottom 26. The back 25 and bottom 26 are attached togetherby a pivot rod 27 which passes through the eyes 42a of an L-shaped' back supporting member 42. An L-shaped bottom bracket 28 is designed to extend up behind the seat back 25. When the seat is in an open position the bracket 28 abuts the back 25a. of the seat back 25 thus holding the seatbottom in the proper position. As is indicated at A in Figure 3, the seat may be folded up against the back.

.A pair of arms 29 are provided along the sides of the seat member 24. A bale shaped retaining rod 30 passes through the ends 29a of the arms 29 and is bent downwardly at 32 and outwardly at 34 to provide the rigid supporting rods 31. The ends of the supporting rod 31 pass through the frame 11 and have enlarged beads 33 holding them in place. This provides a pivotal connection of the rod 31 to its frame section 11. This construction allows the seat to pivot both at arms 29 and the frame 11. r I

As shown in the drawing, a pair of'curved coil springs 35 are disposed in inwardly tapering rearward angulation and have one end 35a connected to the extensions 13b of the frame 13 and the other end 35b connected to the ends of the arms 29. The structure isnot limited to coil springs, and other types such as zig-zag springs may be used. In order to make a sturdy connection the ends of'the frame extension 13b and its arms29 are I inserted into the interior of the. springs 35. A strap clamp 36 further passes around each of the springs and its arms 29. The seat mounting rod 38 passesthrough theeyes 42b on the back supporting member'42 and through the strap clamp 36. These ends: are threaded to receivetthe. butterfly nuts 37, which hold the; seatina PatentedMar. 14, 1961 body receiving position and lock the spring 35 on the arms 29.

A perambulator bale 39 is provided for use in converting the rocking support into a perambulator. The bale has a pair of wheels 40 mounted for rotation'on'the short axles 43 near the outer ends of the bale legs 39a. A pair of L-shaped slots 39a and 3% are provided near the middle and the end of the bale respectively. These slots are adapted to receive the bent portions 34 of the retaining rod 30 and ends a of the axle 15.

The bale 39 thus locks the rocking support in a substantially steady position since it limits spring action.

As is described in my above referred to patent, the rocking support, when in operable position, is designed to allow the operator to rockably move back and forth against the resilient support of the spring 35 rocking around the pivots of the retaining rods 30. When it is desirable to store the rocking support it may be converted into a substantially flat package. First the set screws 4-1 are loosened and the foot rest 18 flattened out. Next the seat bottom 26 is folded against the seat back and by loosening the butterfly nuts 37 the whole seat 24 is rotated into a substantially horizontal position. The locking rod 17 is then moved out from under the end 13a of the U-shaped frame section 13 and the frame section is'then allowed to pivot on the pins 14 into a position where it is substantially superposed over the U-shaped section 12. As can be seen in Figure 5, this provides a substantially flat rocking support member which may easily be stored in a restricted space.

In opening the support It) the opposite steps are taken.

The support 10 -of-this invention is maintained in operable position by thelocking rod 17. The rod 17 is positioned under-the'ends 13a of the section 13 and thus prevents the section 13 from folding under spring pressure into its normal position superposed over the section 11. Since the rod 17 pivots at 17b and 170 and has the portion 17d which is spaced from the line of pivot, it is adapted to be swung out of the way when its support is being opened from a folded position by the ends 1311 of the section 13. Thus, the ends 13a abut the rod 17, move it aside until the ends 13a are passed, at which time the rod 17 falls due to gravity under the section 13 and thus positively holds it against spring pressure. Grooves 13d in the underside of the

tube sections

13b and 13c are shaped to receive the rod 17 in locking position.

If it is desirable to convert the rocking support into a substantially steady support, the perambulator bale 39 is added. Since this also provides Wheels at the four corners of the device, it also converts the support into a perambulator which may be pushed by the bale 39.

The foregoing detailed description is given for clearness of understanding only and no unnecessary limitations should be understood therefrom as some modifications willbe obvious to those skilled in the art.
