DETAILED DESCRIPTION OF EMBODIMENTS
Attention is first directed to FIGS. 1 and 2 of the drawings showing a toy mobile according to a first aspect of the present disclosure, generally designated 20. The toy mobile 20 comprises a support unit generally designated 24, which in the illustration of FIG. 1 is shown articulated to a side wall 26 of a playpen or the like (not shown).
The toy mobile 20 further comprises a support post 30 articulated at its bottom end to the support unit 24, and carrying at its top end a mobile assembly generally designated 38.
The support post 30 is a rigid elongates structure, which according to one example is rigidly fixed to the support base, though according to other examples is detachable attachable to the support base, however in a fixed fashion. Furthermore, according to a particular example, the base unit comprises a power source (e.g. a battery pack; not seen), whereby electric power to the mobile assembly 38 is transferred thorough electric wiring extending through the support post 30.
It is also appreciated that whilst in FIG. 1 the toy mobile is illustrated attached to a side wall 26 of an infant enclosure, the toy mobile can just as well be extend from a wall or a ceiling, or can be positioned on a surface, providing that the base unit is properly supported.
The mobile assembly 38 comprises a hub 40 (to which particular reference will be made hereinafter) to which three bifurcated object supports 44 are rotatably engaged. According to one arrangement, the bifurcated object supports 44 are detachably articulated to the hub 40. The bifurcated object supports 44 have a stem portion 46 (see also FIGS. 2 and 3) branching into a first arm 48a and a second arm 48b. Each of the first arms 48a and a second arms 48b carry at their free end a geometric mobile object which are typically themed pairs, e.g. a rabbit R and a carrot C, etc., each dangling from the free end of a respective arm by a short cord.
It is noted, best in FIG. 2, that the arms 46a and 46b of an object support 44 are curved and extend non-coaxial with the stem portion 46 (FIG. 2C) and such that at a top/bottom view (FIG. 2A) the first arm 46a and the second arm 46b are angularly offset with respect to one another by angle α, and at perpendicular view (FIG. 2B) the projection of one of the arms (48b in the illustration) extends above the projection of the other respective arm 46a. The outcome of this arrangement is such that the first arm 48a and the second arm 48b are disposed spaced apart from one another such that when one geometric mobile C object extends above another geometric mobile object R (and vise versa), the two geometric mobile objects do not interfere with one another, and will not tangle during animation thereof. It is thus seen in FIG. 2C that the vertical, planer distance D between the free end of the respective first arm 48a and the second arm 48b is shorter than the three dimensional distance L extending there between.
Turning now to FIGS. 3A to 3C reference is directed to the hub 40. The hub 40 is egg-shaped and comprises a top shell 52 and a matching bottom shell 54. The top shell 52 is fixedly articulated to the top end of the support arm 30 (i.e. non rotatably). Encapsulated within the top shell 52 are provided an electric motor 56, a retaining disc 58 through which an axe pin 60 extends, said pin being coupled to an output shaft of the motor 56. A spring biased lever 64 is pivotally articulated at 66 to the retaining disc 58, with a lever arm 68 configured for projecting through as recess 70 in the top shell 52. Lever 64 is further configured with at least one arresting tooth 72, the purpose of which will be discussed hereinafter. Motor 56 is electrically coupled to a power source, e.g. a battery pack received within the support unit 24, through wires extending through the support post 30. Alternatively, a power source can be configured at the hub 40.
The bottom shell 54 is rotatably articulated to the top shell 52 and accommodates a friction gear train 76 wherein three beveled output gears 78 are equi-angularly disposed, with axles of rotation 82 disposed co-planner and each having a coupler bit 84 radially projecting from openings 86 formed at the bottom shell 54. The coupler bits 84 are configured for detachably attaching thereto an object support, such as object support 44 discussed hereinabove, or of the type disclosed herein below as will be discussed in connection with a different example.
The gear train 76 is positioned and compacted within the bottom shell 54 by a retention ring 88, screw coupled (or otherwise fastened) to the bottom shell 54. A bevel input gear 92 is disposed at a right angle to the beveled output gears 78 and is freely to rotate about the axle pin 60. The bevel input gear 92 comprises at its perimeter with several arresting teeth 94, said teeth 94 being configured for selective arresting by the arresting tooth 72 of the lever 64.
Further noted, at the assembled position, a hexagonal bottom end 61 of the axle pin 60 is engaged within a corresponding hexagonal socket 98 of the bottom shell 54.
The arrangement is such that upon activating the motor 56, rotary motion is imparted through axle pin 60 directly to the bottom shell 54 thus imparting the bottom shell rotary motion in direction of arrow 100 (FIG. 2A). Once the lever 64 is displaced in direction of arrow 102, the arresting tooth 72 of the lever 64 engages teeth 94 of the input gear 92, resulting in imparting rotary motion to the three beveled output gears 78 and thus generating rotary motion of coupler bits 84 in direction of arrows 108.
It is thus appreciated that the motor imparts rotary motion which in turn is converted into a first rotary motion of the bottom shell 54 of the hub with the articulated bifurcated object supports 44 (and the geometric objects R and C dangling therefrom) in a yaw-like motion about the center axis of the hub, and a selectively operated second rotary motion of the object supports 44 (and the geometric objects R and C dangling therefrom) in a roll-like motion about the axis of the axles 82.
Thus, during course of activating the second rotary motion (i.e. about radial axes 46 in direction of arrows 108) the dandling geometric objects R and C are animated as the arms 48a and 48b revolve, retaining their suspended position under force of gravity.
Turning now to FIGS. 4 to 6 there is illustrated a toy mobile according to a second aspect of the disclosure, generally designated 200. The toy mobile 200 comprises a support unit generally designated 202, with a support post 208 articulated at its bottom end to the support unit 202, and carrying at its top end a mobile assembly generally designated 212. The mobile assembly 212 is configured a hub 216. It is appreciated that the support unit 212, the support post 208 and the hub 216 can be substantially similar to corresponding elements disclosed in connection with the previous example, respectively, and reference is made thereto.
Articulated (fixedly or detachably) to the output couplet bits (84 in FIGS. 3A, 3B and 3C) there are object supports generally designated 220, having a generally bifurcated shape and each comprising a rigid curved first arm 232 and a concave second arm 234, the later extending from the first arm so as to give rise to the bifurcated configuration.
Dangling at a free end of the first arm 232, through a short cord 238 there is provided a first geometric mobile object 242 (animal figures in the illustrated example). The second arm 234 is leaf-like shaped constitutes a second geometric mobile object and is fanciful (e.g. the color, shape and pattern can conform in theme with the first geometric mobile object 242). It is appreciated that the dimensions of each of the first geometric mobile object 242 is selected such that it is smaller than the dimensions of the corresponding second arm 234 (namely the second geometric mobile object). This is illustrated in FIG. 5 (when viewed from below, in the direction of arrow 249) and better so in FIGS. 6A to 6K, as will be discussed hereinafter. As the motor unit (designated 56 in the previous example) is activated, a first rotary motion is imparted to the bottom shell 54 of the hub 216, with the bifurcated object supports 220 articulated thereto, rotating in direction of arrow 250 (in a yaw-like fashion, about the center axis of the hub 216). At this position the first geometric mobile objects 242 and the second arms 234 maintain their relative position.
Once the lever 68 is shifted into engagement with the input gear 92 (FIG. 3A) a second motion shifts in, wherein the bifurcated object supports 220 begin to revolve (in a roll-like fashion about the axis of the stem 84). As a result of this motion the first geometric mobile objects 242 and the second arms 234 spin about one another, whereby a first geometric mobile objects 242 are periodically/alternatingly hidden by the respective second arms 234.
FIGS. 6A to 6K are sequential images illustrating incremental rotational displacements of the mobile, from a baby's view, viewing the mobile from below, i.e. viewed in direction of arrow 249 in FIGS. 4 and 5. It is seen that the first geometric mobile objects 242 are periodically hidden by the respective the second arms 234. In FIGS. 6E, 6F and 6G the elephant E is hidden by the Orange leaf O. likewise, in FIG. 6F the chick C is hidden by the Blue leaf B, etc.
It is appreciated that the first geometric mobile objects can be hidden simultaneously or at alternating sequences, depending at the angular setting of the bifurcated object supports 220.
This arrangement offers a child watching the mobile an animated experience, with the mobile objects playing ‘hide and seek’ or ‘peek-a-boo’ with the child.
Turning now to FIGS. 7A and 7B, example of support units are illustrated, for use in conjunction with a toy mobile of the present disclosure according to either aspect thereof.
FIG. 7A illustrates a support unit generally designated 270, configured with a light projecting portion 274 for projecting light (e.g. stars or other shapes) towards a ceiling. The support unit 270 further comprises a soft illuminated image 276. A battery compartment (not seen) is provided at a back face of the support unit. This power source serves also for powering the motor unit 56 discussed above. A plurality of controls are provided, such as illumination/light controls 278, audio source select 280 (AUX port, pre-programmed chip, etc) with volume controls 282 and 284 for playing soothing sound through speaker 286.
As already mentioned herein above, the support post 30/208 can be fixedly attached to the support unit 270, or it can be detachable attachable thereto. In the example of FIG. 7B the support post 30/208 has been detached and the support unit 290 is used as a mini activity center providing sound and light activity, e.g. through a plurality of touch keys 292 and speaker 294, with volume controls 296.
