Lakin, Slinger, Wis., assignor to Marlin Toy Products, Inc., Horicon, Wis., a corporation of Illinois Filed Nov. 14, 1966, Ser. No. 594,146 Int. Cl. A63h 13/20 US. Cl. 272-31 13 Claims ABSTRACT OF THE DISCLOSURE The subject matter relates to carrousel and roundabout toys and the like having a rotating platform with individual motion objects carried thereon and motivated by corresponding spindle means having rollers driven by frictional engagement with stationary arcuate surfaces beneath the platform, the disclosures providing a novel platform or carrier structure molded in one piece to include an integrated central driving gear and platform structure with radially-located, rockable bearings for the shafts, and stationary roller drive formations of ridge-like character formed as an integral part of a support and so situated and constructed as to impart either unidirectional or intermittently reversing action to the individual motion objects.

The improvements disclosed and claimed relate to a motion toy of the roundabout and carrousel type including a rotatable platform or carrier which may be driven by power taken from the windup motor of a music box.

Individual motion elements or figurines of desired configuration are mounted on the rotatable platform and are themselves rotatable or pivotable about individual axes.

One of the important features of novelty is the means for mounting the individual motion elements for pivotal motion whereby corresponding spindles there-of are rockable laterally and shiftable longitudinally or axially as an adjunct to individual drive means deriving power from the rotation of the carrier, wherein the spindles depend below the surface of the carrier platform and are equipped with roller means adapted to travel through a circular path and run along the arcuately extensive sloping face of a stationary drive formation beneath the carrier;

Wherein these drive formations are in the nature of upstanding arcuate ridges located about the carrier axis and the spindles have tires disposed to run along a sloping side face of these ridges;

Wherein the side faces slope in a way such that the spindle drive means or tires can ride upwardly thereon to automatically adjust to an optimal driving relation therewith by reason of the lateral and axial shiftability of the spindle means;

Wherein the ridges are arranged in sets each lying in concentric circles radially spaced one from another to define between the sets a circular path or alleyway in which the spindle tires travel, the drive ridges in each such circular set being interrupted in alternation so that the spindle tires will first drivingly engage a ridge in one set, and then a ridge in the other set, whereby the spindle means and the appertaining motion elements will be caused to oscillate;

Wherein the carrier is of a unique structural design feasibly moldable in a single integrated unit providing a central drive gear surrounded by a plurality of radiallysituated bearing sockets each seating one of the spindles for the axial and lateral adjusting action aforesaid, by reason of which, together with the particular form and location of the stationary drive formations or ridges, the roundabout structure can be economically produced and driven by power taken from a small spring-driven music United States Patent 3,498,603 Patented Mar. 3, 1970 ice box motor without unduly loading the latter or interfering with the proper sound and music efiects thereof.

Still further aspects of novelty and utility relate to details of the preferred commercial embodiment of the toy more particularly described hereinafter in view of the annexed drawings, in which:

FIGURE 1 is a perspective view of one embodiment of the toy;

FIGURE 2 is a bottom plan view of the same;

FIGURE 3 is a vertical section with parts shown in elevation;

FIGURE 4 is an interior plan view of the base section;

FIGURE 5 is a fragmental perspective enlargement of the interior of the base section, the rotatable carrier, and the oscillatory drive means;

FIGURE 5-A is a magnified perspective fragment of the lead-in configuration on one of the driving ridges;

FIGURE 6 is a bottom plan view of the rotatable carr1er;

FIGURE 7 is a fragmental exploded perspective of parts of the carrier and figurine structure.

The embodiments of the toy seen in FIGURE 1 comprises a molded, dish-shaped base section 10 having an upper rim portion provided with a flange 11 having a recessed ledge 12 (FIGURES 3 and 4 also).

An approximately semi-spherical dome 14 of molded transparent, non-shattering plastic has its lower margins seated in the ledge, there being at spaced positions around said margin lateral tabs 15 which fit into recessed seats 16 in the base ledge, FIGURE 4, the dome being secured by rivets 17 through said tabs and rim seats.

Secured on the floor of the base section, FIGURE 4, is a motor means 18 in the preferred form of a wind-up music box of known construction and including particularly a tone drum 19 driven by a coaxial bull gear 20, the teeth of which are exposed at the upper face of the casting 21 opposite a winding spindle 22 projecting in a vertical plane in the normal position of the device. Circumambient of said spindle is a recess or seat 23 opening sidewise at 24 in juxtaposition with the exposed teeth of the bull gear, it being understood that the usual helical driving spring (not seen) is contained in a shell 25, FIGURE 3, and tensioned by turning of the spindle 22, said spring driving a gear system of known arrangement (not seen) having driving engagement with the bull gear to rotate the tone drum in the usual manner.

A figurine carrier 30 of the construction shown in FIGURE 6 is effectively totally supported for rotation in the aforesaid seat 23 in the motor casting 21. The carrier consists of a main ring 32 provided at equally spaced intervals thereabout with integral secondary rings 34 each interrupting the continuity of the main ring so as to provide a gap, the gap in each secondary ring being spanned by a relatively thin web 36 extending approximately diametrically of the secondary ring and approximately in alignment with the median circumference through the main ring and tending to appear as a continuation or interconnecting Web across the said gap. The main and secondary rings are contained in a first plane, which is normal to the axis of rotation of the carrier, as will more fully appear; and each of the diametric webs 36 is substantially flat and contained in a plane at right angles to the plane of the rings.

The'carrier is molded from a synthetic plastic material having a degree of flexibility such tht the diametric webs 36 can twist somewhat about the long axis therethrough. Integrally formed with each diametric web 36, centrally thereof, is a depending tubular bearing or socket member 38, FIGURE 7 also, which can be rocked laterally somewhat from a normal central position as permitted by the web member of which it is a part.

Disposed centrally of the main ring 32, and connected to the secondary rings 34 by spokes 39, is a hub member 40, FIGURES 6 and 7, having a bored tubular central sleeve formation 41, a polyhedral upper shoulder 42, and a ring of gear teeth 43 on the underside or lower axial face thereof, the diametric dimension of the lower portion of said hub including the set of gear teeth being such as to fit freely but closely within the seat 23 in the music box casting, as at 21X in FIGURE 3, the carrier structure being formed symmetrically so as to have a balance permitting it to stand supported in the music box seat, as aforesaid, in which condition the gear teeth 43 are in driving mesh 'with the teeth of the bull gear 20, and since the latter gear is driven by the spring motor of the music box, the carrier hub will be rotated about the windup spindle 22 which stands above the surface of the casting and projects freely somewhat into the bore 41A of the hub and affords a center about which the carrier turns. The end 41B of tube 41 extends downwardly toward the floor of the seat 21X, within the hub, as in FIGURE 7.

The carrier is thus part of a roundabout structure having a hub with gear teeth supported in a seat adjoining a music box bull gear in accordance with disclosures and features claimed in my US. Patent No. 3,279,793, there being special features of further novelty in the presently disclosed constructions, as will appear more fully hereinafter.

In order to wind the spring motor, a long knob spindle 44 is passed through an opening at the top of the transparent dome 14, the lower end portion of said spindle being reduced to accommodate a coil spring 45 and having an internally threaded bore 46 (FIGURE 7) engageable with the threaded end 22X of the spring wind-up spindle, the long spindle rod being surmounted by a decorative knob 47 at the top of the dome, turning of which winds up the music box motor, the shoulder 48 at the reduced lower end of the rod serving to capture the carrier in its seat, while the spring 45 yieldingly urges the carrier into its seat to maintain the gear teeth in mesh.

In order to make the carrier structure as light in weight as possible while giving it a non-warping rigidity, it is formed mainly in channel shaped cross section, as indicated at positions 31 in FIGURE 7. The winding rod is concealed from view within a tubular central column 50, FIGURES l and 3, of inverted conical configuration with polyhedral sides 51 adapted to interfit and couple with the polyhedral configuration of the shoulder 42 on the carrier. Fitted upon the upper margins of the column is a canopy member 52 having a polyhedral rib formation 53 mating with the like configuration of the column, the canopy further having a central tubular bore 54 freely passing the knob rod. Thus, the circular carrier is rotated by meshing of its gear teeth with the bull gear on the music box, and the canopy structure rotates with the carrier by reason of the polyhedral interfit of the foot of the column with coupling formations on the hub of the carrier.

As seen in FIGURES 1 and 3, a plurality of motion elements or figurines 60 are supported by and move with the carrier, said elements having the detailed construction seen in FIGURE 7 and consisting in a table or platform portion 62, which is itself a secondary carrier on the main carrier. Each table portion has a depending stem spindle 64 integrally molded therewith and freely fitting into the socket bearing 38 on the carrier, each said stem having near its upper end a bearing collar 65 which enters the bore to space the spindle in said bearing. Close to the lower extremity of each platform or subcarrier spindle 64 is an annular groove 66 adapted to seat an annular friction element or tire 67, said stem spindle terminating in a chamfered or conical point or tip at 64X for purposes to appear. The length of each subcarrier spindle 64 is such that it depends beyond the lower extremity of the tubular socket bearing 38,

FIGURE 3, so that it can rise and fall therein in driving coaction with certain drive means to be described.

Means for imparting motion to the individual subcarrier and figurines, as a function of the rotation of the main carrier structure supporting them, comprises the provision, as in FIGURES 4 and 5, of sets of upstanding arcuate ridges 70A and 70B formed as an integral part of the base section 10, said ridges being arranged in inner and outer circles concentric with the center of rotation of the carrier and therefore with the axis through the wind-up spindle 22.

The ridges 70A are grouped in the outer circle while the ridges 70B comprise the inner circle, there being a space (measured along any radius from the center of rotation in spindle 22) between the inner sides or faces of the outer ridges and the outer faces of the inner set of ridges, this space corresponding to the orbit travelled by the several friction drive elements or tires 67 during rotation of the carrier 30. As seen in FIGURE 5-A particularly, each ridge formation is wider at its base 71 than at its top 72, the inner and outer sides or faces thereof tapering upwardly toward a peak, from which it follows that the circular raceway 74 in which the subcarrier tires travel between the circular sets of arcuate ridges, is narrower at the bottom level than toward the upper or peak portions of the ridges flanking and defining said raceway.

FIGURE 5 depicts the disposition of one of the frictional drive elements or tires 67 in the aforesaid raceway between the sets of ridges, the orbit or path of travel of the tires and appertaining subcarrier stem spindle being indicated in dotted lines in both FIGURES 4 and 5. The weight of the individual subcarrier or tables is sufficient to cause the spindle stem to descend to the limit in its socket bearing to the limit permitted by the table members 62, and this level is such that the tip 64X of the spindle just clears the floor of the base section while disposing the appertaining drive tires near the narrower lower zone of the raceway so that the tire is positively and firmly in position for driving engagement with the side or face of the ridges in both inner and outer sets at the time of approach to the beginning or leading end of said ridges in a manner sought to be indicated in both FIGURES 3 and 5, the latter view taken with FIGURE 4, also illustrating the fact that the spacing of the ter minal portion 75 of a ridge in the inner set with respect to the beginning or leading portion 76 of the adjoining ridges in the outer set is such that the spindle stems can drop to the lowest level in reaching this point so that the appertaining tire will be disposed to engage the next following ridge at the wider part thereof with such degree of firmness that the spindle will tend to be swung sidewise slightly to assure good driving contact, the lateral yieldability of the web portions 36 supporting the spindle bearings 38 in the gap in the several small carrier circles permitting such adjustment.

As the main carrier rotates from a position at which the drive tire 67 on any leg leaves a ridge in one set to engage the next ridge in the other set, as in FIGURE 5 for example, the tire will tend to climb up the face of said next ridge owing to the slope thereof and seek an optimal driving position in which the weight of the subcarrier will maintain it during the advance along said ridge, the spindle or stem members 64 shifting upwardly in their bearing sockets in this automatic level-seeking and drive-adjusting action. To further facilitate a smooth transition of the subcarrier drive means from one ridge to the next, the leading margins of the driving faces of the ridges in each set are relieved as at 77 in FIGURE 5-A to provide a lead-in angle most favorable to establishing immediate driving contact between the advancing tire and at an angle most favorable to produce immediate tendency of the tire to bias upwardly along the side of said ridge in seeking its optimal driving level thereon as aforesaid, so that a smoothly continuous alternation in the resultant driving force applied to the subcarrier will result.

It will be understood that the driving forces applied to the subcarrier drive means, particularly the tires 67, as the main carrier structure rotates, act in reverse directions depending upon whether the tire engages a ridge in the inner or outer set, in consequence of which an oscillatory motion is imparted to the subcarrier tables in the case where the ridges in each set occur in sequential alternation, for instance as depicted in FIGURE 4, it being further understood that other arrangements of the ridges are possible to provide different motion effects.

Any suitable configuration may be employed for the figurines 60, to be carried by the table or platform elements 62, and the spacing of the subcarriers may be such as to cause them all to move in unison or differently. However, since the power supplied by the conventional music box motor is relatively slight, most satisfactory results are obtained from a symmetrical disposition of the subcarriers and the distribution of mass therein and in the main carrier which will cause the minimal loading on the available power and drive means. In this connection, the self-levelling automatic drive-adjusting action of the subcarriers heretofore described is of utmost importance and serves the further purpose of preventing variations in the rate of rotation of the tone drum of the music box.

In order that the motions of the several figurines may be dependably constant without impairment of the functioning of the music box, the fit of the spindles 64 in their respective socket bearings 38 must be quite free and of a character to inhibit binding. To this end the spindles should be formed with a slight downward draft or taper beginning at the collar 65, the latter fitting freely down into the socket or bore and serving as an annular spacer bearing to contact the inner wall of the socket bearing somewhat loosely as the major bearing and contact surface which the spindle will have in both rotary and axial motion. By this means the surface area of bearing contact is minimized to reduce frictional loading on the bull gear and music box motor, the axial and lateral degrees of movement of the bearing sockets similarly minimizing the loading effects at the point of driving contact of the spindle tires 67 with the complex angularity of the driving ridges, for reasons previously explained.
