azfimn w United States Patent 3,180,640 REVOLVING ROCKING HORSE Donald K. Lawrence, 531 W. Addison St., Chicago, Ill. Filed May 24, 1963, Ser. No. 283,016 8 Claims. (Cl. 27233) My invention relates to an improvement in a rocking horse, and more specifically, to a rocking horse of the character in which the body of the horse may be caused to rotate during the course of a childs play thereon.

My invention has for a particular and major objective the provision of a rocking horse having such capability of movement incorporated in it and the mechanism whereby such movement is provided. The presence or absence of such movement and the direction of it is immediately under the control of a child riding the horse, and the medium of control is the reins, normally used, so that the simulation of reality is of a high order. My invention is particularly notable notonly for these features, but also, in the mechanism itself, for the simplicity and inexpensiveness thereof, for the fashion in which the need for members of great strength is avoided and for the enclosure of moving or otherwise dangerous parts which might offer a hazard to a child playing on or with the toy.

. These and other objects and advantages of my invention will be apparent from the following description and drawings, of which:

FIG. 1 is a perspective view of a rocking horse incorporating my invention, broken away in part to illustrate interior details;

FIG. 2 is a section taken substantially along the line 22 of FIG. 1 looking in the direction of the arrows;

FIG. 3 is a section taken substantially along the line 3-3 of FIG. 2 looking in the direction of the arrows; and

FIG. 4 is a section taken substantially along the line 7 44 of FIG. 2 looking'in the direction of the arrows; and

FIG. is a section taken substantially on the line 55 of FIG. 1 looking in the direction of the arrows.

In FIG. 1, I show a rocking horse of a type commonly seen on todays toy market. The type consists of a sup porting frame 10 made of lengths of tubing which are joined side-by-side at the central sections thereof, as by a clip 12, and diverge at each end beyond the clip. The extremities are turned upward as at 14.

The belly of a molded horse body 16 has a post extending downwardly therefrom to which are secured an apex 18 of a pair of triangular spring brackets 20 extending fore and aft of the horse body. Springs 22 interconnect the outer apices 23 of the spring brackets 20 to the adjacent upturned ends 14 of the frame 10.

p In normal practice the post is rigidly connected to the horse body and extends well up inside its interior to provide support for the saddle portion of the molding. A shaft extends forward from the'upper end, of the post inside the horses neck for a handle mount to steady the child and to prevent rotation of the-horse body on the post. The structure as thus far described is entirely conventional and well known.

4 The mechanism whereby the above-described rotation of the horse body relative to the frame It) on which it rests is obtained consists of substituting a tube 24 for the above-described post. The'tube mounts a saddle support 26 at its upper end to underlie and support the saddle 28 of the molding. The tube is open at its lower end,. the lowerend 30 extending below the horse body. The neck 3,l3,b4 Patented Apr. 27, 1%65 Ice saddle and neck supports may be integral and formed, for instance, of appropriately bent rod. The saddle support 26 may be welded to the top of the tube 24.

In the illustrated embodiment, the forward tip 35 of the neck support is of reduced diameter and mounts a bar 36 hereafter referred to as the bit. The bit has a hole through its center to receive the reduced end of the neck support and is secured in place for pivotal movement by a washer 38 and cotter pin 40. The bit extends out through a flexible resilient neck portion of the body equally on each side, and reins 42 are riveted to the outwardly extending ends. Immediately inside the body 16 on one side of the pivot 35, avertical hole 44 is bored through the bit to receive the downturned end 46 of a rearwardly extending rod 48. The tip 46 is secured Within the hole 44 by a cotter pin 50. The hole 44 is substantially spaced from the pivot 35.

Rod 48 is connected at its rearward end to one arm 52 of a vertically oriented bell crank 54 which is pivotally mounted as to a plate 56 secured to the top of the tube 24. The other arm 58 of the bell crank has a downwardly extending rod 60 secured thereto.

To fulfill the purposes of my invention, the horse body 16 must rotate relative to the frame It). To this end a tubular bearing 62 is rotatably mounted on the exterior of the lower end 30 of the tube 24 and contained between rings 64 which are secured to the lower end 30 of the tube 24. The apices 18 of the spring brackets 29 are secured to the exterior of the bearing 62. The rings 64 and bearing 62, as is evident, lie below and outside the body of the horse 16.

A shaft 66 is mounted by a universal joint 68 to the top of the clip 12 in a position vertically under the tube 24. The shaft extends Well up inside the tube and at its upper end 70 is reverse threaded. In other words, as illustrated here, there is a left and a right hand double spiral thread superimposed on each other. The shaft has a diameter considerably less than the internal diameter of the tube 24. The universal joint permits an in clination of the shaft in any direction, but prohibits any rotation thereof.

A driving assembly 72 is engaged on the'reverse threaded portion of the shaft 66 and secured within the inside of the tube 24 to effect interengagement between these members and cause the horse to rotate as desired. Reading down from the top, the assembly consists of a top retainer ring 74 secured as by rivets or set screws 76 to the wall of the tube 24, a ball bearing ring 78, an upper driver'fiti, a spacer 82, a lower driver 84 and a lower retainer ring 86, again secured by rivets or set screws 88 to the wall of the tube. The spacer 82 is independent of the drivers 80 and 84. The upper retainer ring 74 and the ball hearing-ring 78 stand clear of the shaft 66. The upper driver ringStl is an annular member interiorly threaded as at (FIG. 3) to engage the right hand threads of the threaded end 70 of the shaft as. The driver is provided with a plurality of vertical ribs 2 on its external surface; inside surface 94 of the tube 24. The spacer 82 stands free of both the tube and the shaft. The lower driver 84 is identical with the upper driver except that its internal threading engages the left hand threads of the upper end of the shaft 66. The lower retainer ring 86 stands clear of the shaft 66.

The tube 2 4 has a vertical slot 96 formed in the wall thereof extending over and between the drivers 3% and 84, and a sliding shift assembly 93 is secured over the slot.

support or arm 32 extends forward fromjthe saddle support 26 to a point generally behind or-within the head of the horse directly under the crest-and bends generally vertically downward at its forward end as at 34; The

The shift assembly includes a pair'of plates ltltl and12 mountedtogether face-to-face. The plates have aligned longitudinal slots 104, and headed screws- 1% extend through the slots and into the tube at either end of the tube The ribs 92 approach closely the v heads 112 of the pawls.

slot to mount the two piates for vertical sliding movement over the tube slot 96. The two plates mount an upper and a lower pawl N3 and illtl having square heads 112 and square shanks 114. The shanks of the pawls extend through the tube slot 96-and into the interior of the tube in aposition to engage the drivers 8i) and 841 The mounting of the pawls is achieved by providing square holes in the generally flat, or transversely curvedto conform to the curvature of the tub e-inner plate 182 The outer fitting closely the shanks 114 of the pawls. plate 1% has a boxlike outer projection 116 formed thereon as by stamping which. encloses the heads of the pawls. V.

It will be appreciated from the confinement of the shanks of the pawls in the square holes in the inner plate 192 and the sides of thepawl heads 112 within the boxlike projection 116 that the pawls areheld securely against rotation. The inner ends of the pawl shanks are vertically beveled, as at'lz to provide a heel 126 and a toe 128 parallel with theribs 92 of the drivers. When the pawls are properly seated with the heads against the inner plate 192, the heels clear the ribs 92 and the toes 128 engage the ribs. As illustrated, the upper pawl 168 has its toe pointedin the counterclockwise direction and the lower trated position where the upper pawl engages the upper driver to a central-position where neither pawl is engaged and to a lower position where the lower pawl lit) engages the lower driver .84. f

The operation of my device will be evident from the foregoing description. A child mounts the horse in the usual fashion. His weight will be sufficient to depress the horse against the tension of the springs 22 connecting it to Y the frame 10. The tube 24 will partially collapse telescopically on the shaft 66. Let it be assumedthat the bit 36 is in a transverse position with respect ot the axis of the horse body. In such case the bell crank 54 will occupy a central position and the shift assembly 98 also a central position with the pawls 19S and 110 opposite the spacer 82 and disengaged from the driving members 80 and 84. In the course of such initial settling movement,

' the upper driver will rotate in. a clockwise direction and the lower driver ina counterclockwise direction, but since'the pawls are disengaged, there willbe no communication of this rotation to the -tubef24. The child may bounceupand downon the horse, and the drivers will'follow their respective threading in thecourse of such up and down movement withoutinfluencin'g the tube 24 and therefore the orientation of the horse. There may be sufiicient frictional engagement between the bearing 62 and the lower end 30 of the tube to preventany unwanted rotation.

Assuming now-thatthe child wishes the horse to start rotating to the right, he will pull on the right rein. The,

bit will be pivoted to move rod 48 forward, thereby rock- 'ing the bell crank 54 to ,raise .rod to move the shift 5 assembly 98 upward to the position illustrated in FIG. 2

and FIG. 3, with. the upper pawl 103 engaging the upper,

driver .80. Asthechild; now bounces the horse downward,

the upper driver will be rotated clockwise, and the pawl,

being engaged with the drivenwill compel similar rotation of the tube, 24 carrying the horse body with'it;

I compel the tube 24 to follow.

Upon the rebound the horse body, the upper driver will of course be driven in the counterclockwise direction. The

I hell 126 of the upper pawl, however, will permit the passage of'the ribs Zthereunder and so permit a free rotation of the driver independent of the horse body. Each successive downward bounce therefore will cause the horse to migrate to the right as long as the bit is held in'the described position.

Similarly, pulling the left rein will move rod 48 to the rear to swing the bell crank to move the rod 60 downwardly and cause the lower pawl to engagethe lower driver 84. Thereafter, upon a downward bounce, the lower driver will rotate in a counterclockwise fashion (lookingdown on it), and the toe of the lower pawl will It will be appreciated from the foregoing description that my invention is capable of innumerable modifications. The horse may be. caused to rotate on therebound rather than on the downward bounce by simply reversing the direction of the pawls 108 and. 110. The ,bit, as illustrated, extends out through appropriate holes in the horses neck or head. Since the body is formed ofrnolded rubber or a rubberlike material, the'body itself provides a restoring force for the bit to move it to the central position. Also, when the bit is moved away from the central position, the horses head will follow, which will enhance the illusion of reality. On the otherrhand, the bit may be confinedin slots in the body, molding for free movement, and other resilient bit restoring means may or'may not be provided. The bit may belocated in the horses mouth unless the linkage operating the shift assembly =8 becomestoo complex. The bit, or its equivalent, may. be situatedfor foot operation. Entirely other operating means such as a push rodor a pushbutton may be em- I ployed to move the shift assembly. The: shift assembly might conceivably be located outside the horses' body and operated directly; t I

The shaft 66 and tube'24-may be'reversed in position with the shaft'constituti'ng the upper member .and the tube the lower. More basically, other meansfor translating up. and down rnovernent into rotational movement will undoubtedly'suggest themselves. 1 f V In the meantime it will be readily appreciated that the rocking horse of my invention achieves its purpose excellently. By the manipulation ofthe reinsa child may bounce up and down, or indeed in any direction as long as there is a lengthening; and shortening of the. telescopic link, and the'horse may turn to theleft, turn to the right, or maintain its straight ahead position. The mechanism by which this is achieved is relatively simple and inexpensive. The forces imposed on the mechanism are slight, and the needfor excessively heavy .members is therefore avoided. For instance, it is not desired that the horse spin violently around but migrate around relatively slowly as the child bounces. Thethread therefore may,

be gradual and the conversion of the ,linearrmovement into rotational movement achievedwithoutgreat mechanical stress.;, The tube 24 and shaft o have no other load bearing functions. The mechanism by which rotation is achievedishoused substantially entirely Within the-,tube z lpand the tube portion containing'it is entirely enclosed within the horse bodyjprotecting positivelya playing child from injury from it. I t j I therefore desire that my invention be regarded as being limited only as setzforth inthe following claims.
