Charles L. Curry Ma /fwd) ATTORNEY CHILDRENS MERRY-GO-ROUND SUMMARY This invention relates to a merry-go-round for children, and it has particular reference to an electrically driven device capable of being compactly folded or dismantled.
A prime object of the invention resides in the provision of an amusement device for entertaining small children indoors or out, and possesses features of .construction enabling the device to be readily assembled for use or folded into a compact unit to be conveniently transported or stored when not in use.
Another object of the invention is that of providing an economical and durable animated-amusement device which is safe for use by children of tender years, having few exposed mechanical parts which could pose any significant accident hazards to the users.
A still further object of the invention is that of providing an electrically driven merrygo-round having adjustable features, such as the shortening or lengthening of the seat arms thereby affording means for balancing these elements with regard to the respective weights of the riders, and providing for necessary restrictions as to space limitations in which the device is operated, such as room dimensions, and the like.
Broadly, the invention is designed to provide a simple and practical entertainment medium by which small children can amuse themselves unattended in relative safety and which can be operated in areas where space is limited, such as indoors, and providing for the ready disposition of the device when in nonuse.
While the foregoing objects are paramount, other and lesser objects will become apparent as the description proceeds when considered in connection with the appended drawings wherein:
FIG. 1 is a perspective view of the invention in its operative condition, the seats being shown in broken lines.
FIG. 2 is a plan view of the invention in which the seats are also shown in broken lines.
FIG. 3 is a side elevational view of the structure shown in FIGS. 1 and 2.
FIG. 4 is a plan view of the invention in its collapsed or folded condition for transportation or storage, the seats having been removed.
FIG. 5 is a fragmentary illustration showing the hub assembly, including the tubular sleeves for telescopically receiving the seat arms which are fragmentarily shown.
FIG. 6 is a fragmentary transverse sectional view, on line 6-6 of FIG. 5, showing the rotary hub element, the nonfriction bearings, the supporting casting and the driving elements.
FIG. 7 is a fragmentary sectional view, on line 7-7 of FIG. 6, through the supporting casting, the driving elements being shown in broken lines, and showing the manner of locking the legs in operative positions, the latter being fragmentarily shown.
FIG. 8 is a fragmentary sectional view showing the manner of locking the leg members in operative positions, one of which is shown fragmentarily, and
FIG. 9 is a fragmentary illustration, partially in section, showing the telescopic association between the seat arms and the tubular sleeves on the hub assembly, and showing the setscrew locking means.
The invention primarily comprises a base assembly composed of a casting 10 which may be rectangular shape, as shown best in FIG. 7, having a bored socket 1 l at each corner to receive the angular upper ends 12 of a set of four legs 13 which, in normal use, extend radially outwardly and have their outer ends 14 bent downwardly to provide foot members having tips 15 thereon, as shown in FIGS. 1,2, 3 and 4.
The upper ends 12 of the legs 13 are rotatable in the sockets I1 and can be secured in either of two rotative positions by elongated screws 16 arranged therethrough and through horizontal bore holes 17 or 18 and threaded into the casting I0, as shown in FIGS. 7 and 8. In FIG. 7 the legs 13 are shown in their extended positions, as indicated in FIGS. I and 2, and in FIG. 8 these members are shown in their folded positions, as shown in FIG. 4. The screws 16 are removed from one of the holes [7 or I8 and inserted in the other to change the position of each leg I3, or a horizontal slot (not shown) may be provided to connect the holes l7 and 18, if desired, so that the legs 13 may be properly rotated without completely removing the screws I6.
The casting 10 is formed with a circular boss 19 on its upper face, a circumferential groove 20 being formed about the boss 19, as shown in FIG. 6. A circular ball race 2] is provided in the upper surface of the boss 19 for a plurality of balls 22 rotatably supporting a hub element 23 having a complementary ball race 24 in the under surface thereof. The hub element 23 is preferably circular and has a depending skirt 25 which embraces the boss 19 and encloses the bearing assembly.
The hub 23 is rotatably secured to the casting 10 by a spindle bolt 26, threaded on its upper end which extends through a central bore in the hub 23, and has a nut 27 and a washer 28 thereon. The lower end of the spindle bolt 26 is enlarged to provide a circumferential shoulder 29 which is rotatably seated in a circular cavity 30 formed in the casting 10, the body of the bolt 26 extending upwardly through a bore 31 centrally of the casting 10, as shown in FIG. 6. A bores socket 32 is provided in the lower enlarged portion of the spindle bolt 26 having a keyway therein whose function will become apparent.
The hub 23 is rotated by an electric motor 33 whose casing is formed with a plate 34 having a plurality of radial ears 35 therearound through which cap screws 36 are arranged by which the plate 34 is secured to a gear housing 37 attached by screws 38 arranged through ears 39 thereon to the casting 10,
as shown in FIG. 6. The shaft of the motor 33 is arranged through the plate 34 and has a small gear 40 thereon which is meshed with a larger gear 41 on a stub shaft 42 joumaled at its lower end in a bushing 43 seated in a well 44 formed in the plate 34. The upper end of the shaft 42 being arranged through the upper wall of the housing 37 and extending into the socket 32 in the lower end of the spindle bolt 26 and is adapted to rotate the latter by reason of a key 45 on the keyway.
Attached to the top of the hub 23, by screws 46, is a plate 47 having an upturned flange 48 on. opposite sides thereof, as shown best in FIGS? 5 and 6, and a plurality of parallel cylindrical sleeves 49 are arranged across the plate 47 having their opposing ends extending through spaced holes 50 in the flanges 48 and welded thereto. The ends of the sleeves 49 are projected substantially beyond the flanges 48, as shown in FIGS. 1, 2, 3 and 4. The hub 23, with the plate 47 attached thereto, provides a carriage for the opposing horizontal arms 51, on the outer ends of which are seated 52, shown in broken lines in FIGS. 1, 2 and 3, which may be of any desired form, and attached by belts or screws 53 to the arms 51.
The arms 51 are elongated U-shaped, and are preferably formed of solid round stock, having the free end of each of the legs 54 thereof telescopically received in one of the sleeves 49, as shown in FIGS. 1 and 2, and slidably adjustable longitudinally thereof to be rigidly secured by setscrews 55, the an rangement being such that the arms 51 are slightly offset from longitudinal alignment without affecting the rotational balance of the mechanism. In addition to the nut 27 on the spindle bolt 26, the hub 23 is rotatably retained on its bearing by a screw 56 threaded through a thickened portion 57 of the hub 23 and extended into the groove 20 formed about the boss 19, as shown in FIG. 6.
In FIG. 4 is illustrated the manner in which the structure can be folded into a compact unit, this is accomplished by removing the seats 52 from the arms 51 and sliding their legs 54 through their respective sleeves 49. The legs 13, which support the assembly in operation, are brought together in pairs and locked in such positions by removing the screws 16 from the bore holes 17 in the casting 10 to the holes 18 therein, or to the position illustrated in FIG. 8 as opposed to the positions shown in FIG. 7. The device may then be conveniently stored or crated.
The invention may obviously be modified in respect to the arrangement of parts without departing from the spirit and intent thereof.
