Description

TOY MERRY-GO-ROUND
The present invention relates to a toy merry-go-round which has a horizontal disc mounted on a vertical support¬ ing column for rotation about the vertical axis thereof and having, at its lower side, a carrying means with at least one horizontal carrying shaft which is adapted to carry a car in a pivotal manner substantially per¬ pendicular to the rotational direction of the disc and which is provided, at both ends, with stop means pre¬ venting axial detachment of the car from the carrying shaft, said car having an upper hanger portion for hanging the car on said carrying shaft, and a lower car portion connected with said hanger portion by means of two side members located on each side of said carrying shaft when the car is mounted thereon. In a toy merry-go-round of this type, the hanger portion and the side members of the car form a unit which is yoke-shaped in cross-section. On assembly of the merry-go-round, the yoke-shaped unit is pushed over the carrying shaft of the carrying means which is attached to the lower side of the disc. The yoke-shaped unit is provided with a complementary portion interconnecting the free ends of the yoke legs, i.e. the side members of the car, and forming the car portion of said car. Since the yoke-shaped unit has been closed by means of the complementary part forming the car portion, the car cannot be removed from the carrying shaft after the merry-go-round has been assembled, unless the carrying shaft has previously been removed.
Assembling the merry-go-round in this manner is complicated and time-consuming work. The present invention therefore aims at providing a toy merry-go-round, the assembly of which has been simplified such that the car can be provided with its car portion interconnecting the free ends of the side members already during manu- facture, and that the car in spite of this can be mounted on the carrying shaft.
This is achieved, in accordance with the invention, by means of a toy merry-go-round which is of the type referred to in the introudction and which is characterised in that the carrying shaft is formed by two journals, and that the extent of the side members in the direction of the carrying shaft, at least in the area adjacent to said carrying shaft, is smaller than the distance between said journals.
In a preferred embodiment, the hanger portion is the smaller part of a substantially circular-cylindrical sleeve longitudinally divided along a chord, the smallest extent of said part transverse to the sleeve axis being greater than the distance between the lower side of the disc and the surface of the journals, the wall thick¬ ness of said part being smaller than the said distance.
The carrying means is preferably formed with an edging which, in regard to the vertical axis of the supporting column, is located radially within and ex¬ tending along the carrying shaft, the distance of said edging to said carrying shaft being insignificantly greater than the wall thickness of the said part.
The invention will now be described in more detail with reference to the accompanying drawings.
Fig. 1 is a side view of a toy merry-go-round ac¬ cording to the invention, only one of its cars being shown;
Fig. 2 is a sectional view of the car along line II-II in Fig. 1;
Fig. 3 is a bottom view of the disc and the carrying means of the merry-go-round, two cars being shown; and
Fig. 4 is a top view of the carrying means.
The toy merry-go-round shown in Fig. 1 comprises a base 1 connected with a vertically extending supporting column 2. The supporting column 2 carries a carrying plate 3 nonrotatably connected with a disc 4 by means of pins 5 (Fig. 4) inserted in corresponding holes in the lower side of the disc 4. The carrying plate 3 and the disc 4 are rotatably connected with the supporting column 2 by means of a screw (not shown) extending through a knurled knob 6 by which the disc 4 and the carrying plate 3 are caused to rotate, and through the disc and said carrying plate into the supporting column 2.
The carrying plate 3 which is adapted to carry three identical cars 7, only one of which is shown in Fig. 1, while two cars are shown in Fig. 3, has three pairs of journals 8 forming, in pairs, the car carrying shafts which are located symmetrically in regard to the vertical axis of rotation of the merry-go-round. The cars 7 are carried by the journals 8 and are pivotal perpendicular to the rotational direction of the disc 4 about the carrying shafts formed by said journals. The carrying plate 3 has, on its lower side, a circumferential edging 9 comprising three edging portions 9a parallel to the carrying shafts of the cars 7 and located within said shafts. The edging portions 9a are so designed and oriented that they substantially form the sides of an equilateral triangle. The circumferential edging 9 also has three pairs of edging portions 9b which form an extension of the edging portions 9a and extend perpendicular therefrom. The edging portions 9b carry, in pairs, the two journals 8 for each car 7 and form stop means preventing axial detachment of the cars 7 from the respective journals 8.
Each journal 8 is substantially in the form of one half of a circular cylinder, the circumferential surface of which is facing upwardly.
The car 7 has an upper hanger portion 7a forming the smaller part of a circular-cylindrical sleeve longi¬ tudinally divided along a chord and having an inner diameter which equals the diameter of the circumference of the journals 8. The car 7 also has two side members 7b extending downwardly from the hanger portion 7a on each side of the journals 8 (see Fig. 2). The free lower ends of the two side members 7b are interconnected by means of a bottom portion 7c.
The height of the hanger portion 7a, which forms the smallest extent of this portion transverse to the sleeve axis, is greater than the distance between the lower side of the disc 4 and the upper portion of the journals 8. The wall thickness of the hanger portion 7a is, of course, smaller than this distance. The distance between the edging portions 9a and the respective journals 8 is insignificantly greater than the wall thickness of the hanger portion 7a. In the area adjacent to the carrying shaft, the width of the side members 7b is considerably smaller than the distance between the jour- nals 8.
On assembly of the toy merry-go-round according to the invention, the carrying plate 3 is first attached to the lower side of the disc 4 by inserting the pins 5 of the plate into the corresponding holes in the disc. After that, each car 7 is mounted on its journals 8, and for this the disc 4 and the carrying plate 3 attached thereto are held upside down, as shown in Fig. 3, where¬ upon the hanger portion 7a, in a position in which the car 7 has been swung inwardly toward the centre of the disc 4, is inserted radially from outside between the journals 8 and the disc 4. The car 7 is then swung into its outer position in which it engages the disc 4 in the manner shown in Fig. 3. After all cars 7 have been mounted on the journals 8, the disc 4 and the carrying plate 3 are mounted on the supporting column 2 attached to the base 1. As will appear from the drawings, the cars 7 of the merry-go-round according to the invention can be mounted on the journals in spite of the fact that they have been provided already during manufacture with a car portion 7 interconnecting the free ends of the side members 7b, which greatly facilitates the as¬ sembly. The various parts of the toy merry-go-round are formed and dimensioned such that the car 7 cannot be swung inwardly into a position sufficiently far inward to allow mounting on the journals 8, and thus removal therefrom, without striking the supporting column 2 which has been connected with the disc 4 and with the carrying plate 3. The different parts are also so designed and dimensioned that the car 7 cannot be swung outwardly into a position sufficiently far out to allow mounting on and removal from the journals 8 without striking the lower side of the disc (the position shown in Fig. 3). In this manner, the car is effectively prevented from detaching itself from the journals 8 during play with the toy merry-go-round.
