This disclosure relates to propeller and frame assemblies for toys.
Toys may utilize various types of components to create propeller assemblies and structures to assist in generating lift for the toy. Various types of control systems may also be used to direct operation of the components. Improvements in electronics and mechanics continue to reduce the weight of the components and also provide additional packaging space to create new toy entities which improve flying play patterns and enjoyment for a user. Also, the desire remains for non-helicopter style lightweight electric motorized interactive flying toys. These may be controlled by a remote control or stable free flight and/or controllable with one or more various hand gestures.
In one embodiment of the present invention there is provided a flying toy. The toy has a housing structure configured to include an upper section, a mid-section and a base section. The mid-section is positioned between the upper section and the base section and is formed by a lower annular band and an upper annular band, which during operation rotate in opposite directions to each other, and further configured to rotate independently of the top portion and base section. The toy further includes a pair of upper propeller blades secured to upper propeller mounts that are extending through the housing structure and are configured for rotation. A pair of flybars secured to upper flybar mounts configured to rotate and further configured to pivot along a vertical plane, and wherein the pair of flybars are configured to extend out of the housing structure. A pair of lower propeller blades secured to the lower annular band, which is configured to counter rotate to the rotation of the upper propeller blades. The toy further includes a power source, circuit board, motor, and gear train all being entirely housed in the base section and configured for operation to rotate a hollow shaft. The hollow shaft is configured to rotate the pair of upper propeller blades and pair of flybars. A main shaft is freely rotatably within the hollow shaft, and the main shaft is rigidly mounted at one end to the top portion and at the other end to the base section such that the upper section and base section are substantially free from rotation when the hollow shaft rotates. The toy further includes a transmitter and receiver pair in communication with the circuit board and positioned against corresponding openings in the base section. The transmitter and receiver being configured to send and receive signals to the circuit board that has programming instructions to control the motor in response to the signals to avoid surfaces and obstacles. In some aspects of the invention, the signals received by the receiver are created from signals bounced from a hand gesture from a user
The toy may further have the hollow shaft press fitted into an upper rotor drive coupler component positioned in the upper annular band and upper section of the housing structure.
The flying toy yet may further define the upper rotor drive coupler component to include (a) a central hub to press fit onto the hollow main shaft, (b) a base section having four arms radially extending from the base section to secure to flanges internally extending inwardly from the upper annular band, (c) a middle section having a pair of middle posts extending outwardly and configured to mount separately to an upper propeller blade mounting structure, and wherein each of the upper propeller blade mounting structures having an end secured to one of the pair of upper propeller blades and further having an aperture at another end to mount onto the middle post, each of the upper propeller blade mounting structures further has a body portion with a pair of legs extending of either side of the middle section of the upper rotor drive coupler component such that the pair of upper propeller blade mounting structures are configured to mate into each other around the middle section to permit a pivotal movement of the upper propeller blades about the middle posts, and (d) a top section having a pair of top posts extending outwardly and configured to pivotally secure to a flybar hub, and wherein the flybars extend from the flybar hub. In this defined embodiment, a pair of the arms, of the four arms, on the base section of the upper rotor drive coupler component may include a channel to accommodate the legs extending from the body portion of the upper propeller blade mounting structures. Yet further, the toy may include pivot links, each of which has an end secured to flybar mounting knobs extending from the flybar hub and having another end secured to upper blade mounting knobs extending from legs of the body portion from the upper propeller blade mounting structure. The pivot links are thus configured to limit pivotal movement to assist in stabilizing the flying toy.
The flying toy in other aspects may include magnets positioned on the lower annular band. A hall effect sensor could then be configured to monitor the rotation of the lower annular band and be further in communication with the circuit board. A programming set of instructions on the circuit board could then control an RPM of the motor to cause the motor to produce a near constant RPM as the power source is depleted.
In yet other aspects, the flying toy may have lower legs formed in the base section to support the flying toy on a surface.
In yet further embodiments, the upper section and upper annular band may have sets of blade apertures and a set of flybar slotted apertures configured to permit the pair of upper propeller blades and the pair of flybars to secure through the housing to respective mounts. The set of blade apertures may be configured at diametrically opposite positions to one another and the set of flybar slotted apertures are offset from the blade apertures and diametrically opposed to one another.
The flying toy may include a three-dimensional object mounted to a top portion that is freely mounted on the upper section such that the three-dimensional object is substantially free from rotation when the hollow shaft rotates. The three-dimensional object may be removably attached to the upper section. Moreover, the three-dimensional object may be a figurine.
The flying toy could further define the gear train to include a shaft gear for rotating the hollow main shaft, and the gear train further includes an end gear in a counter rotation direction to the shaft gear, the end gear being meshed to the lower annular band, such that during operating, the motor rotates the hollow main shaft in one direction while rotating the end gear in a counter rotating direction.
The flying toy could further define the housing structure as a hollow polyhedra or non-polyhedra shaped housing structure having at least vertical symmetry. This could further be defined as a generally hollow spherical, elliptical, ovoid, or cylindrical shaped housing structure.
Numerous other advantages and features of the invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims, and from the accompanying drawings.
A fuller understanding of the foregoing may be had by reference to the accompanying drawings, wherein:
While the invention is susceptible to embodiments in many different forms, there are shown in the drawings and will be described herein, in detail, the preferred embodiments of the present invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit or scope of the invention or the embodiments illustrated.
Referring now to the FIGS, there is shown in one or more of the embodiments a flying toy 100 that includes a housing structure 102 with a figurine 105 positioned and supported on the top of the housing 102. All the components of the mechanism are housed in 102 housing structure, protecting it from impact damage or damage that could occur from interaction with the user. The housing structure includes a bottom portion 112 that has a base 114 defined with three lower legs 116. Landing gear 118 may be further secured to the lower legs to assist with landing or takeoff from a surface.
The housing structure is generally a hollow polyhedra or non-polyhedra shaped housing structure having at least vertical symmetry. In addition, the housing structure more specifically could be generally a hollow spherical, elliptical, ovoid, or cylindrical shaped housing structure. As illustrated only, the housing structure is spherical.
It should further be described that the figurine could be any three-dimensional object mounted to a top portion that is freely mounted on the upper section of the housing structure, which as described herein provides for the three-dimensional object to be substantially free from rotation when the toy flies. In addition, the three-dimensional object is removably attached to the upper section.
The housing structure 102 further includes a mid-section 120 formed by at least one upper portion 132 and an upper annular band 124. Secured to the lower annular band 122 is a pair of lower propeller blades 130. The housing structure 102 further includes an upper portion 132 positioned against the upper annular band 124. The upper portion 132 of the housing structure 102 includes a detent 134 formed to receive a top cap 136 used to secure a mounting base 138 and the figurine 105 mounted thereto.
The upper annular band 124 and the upper portion 132 of the housing structure 102 are positioned against each other to form a top section 140 of the housing. The top section 140 of the housing has formed apertures positioned around various points to allow structural elements to pass through the housing structure 102. The apertures are defined as a set of blade apertures 142 and a set of flybar apertures 146. The set of blade apertures 142 are configured at diametrically opposite positions to one another and defined to accommodate a pair of upper propeller mounts 148 that separately secure to an upper propeller blade 144. The set of flybar slotted apertures 146 are offset from the blade apertures 142 but are diametrically opposed to one another and configured to accommodate a pair of flybars 150 that extend from the housing structure 102 and attach at its end 152 to flybar weights 154. The set of flybar slotted apertures 146 are vertically aligned slots to permit the flybars 150 to have a pivotal range of motion.
In the operation of the flying toy 100, a motor 200, which is powered by a power source 202, drives a gear train 204. A hollow main shaft 206 is pressed fitted or connected into a section of the gear train 204 such that when the gear train 204 operates, the drive gear rotates the hollow main shaft 206. A hollow shaft 206 which is freely rotatable around the main shaft 208 which is rigidly mounts at one end 210 into a shaft cavity 212 positioned in the bottom portion 112 of the housing structure 102. The other end 214 of the shaft 208 is rigidly secured to the 430 (
The bottom portion 112 of the housing structure 102 is uniquely configured to accommodate the motor 200, power source 202, circuit board 220, and sensor components 222, such that everything is configured to hang downwardly from the circuit board 220. The bottom portion 112 has an annular edge 224 that permits the circular circuit board 220 to be situated within the annular edge 224 and secured to mounting points 226 on the bottom portion 112. In addition, between two of the legs 116 of the bottom portion 112 is an elongated cavity 228 to receive and accommodate the power source 202, that may be situated at an angle for proper fit, alignment, and weight distribution. The motor 200 is further situated opposite the power source 202 for weight distribution and is configured to extend into one of the legs 116A. The bottom portion 112 further defines sensor openings 230 to allow the sensors 222 to extend and properly send/transmit/receive signals.
The motor 200 which extends through the circuit board 220 drives a motor gear 300 meshed into the gear train 204, which is housed in a two-piece gear housing 234. The gear housing 234 is mounted to a top portion of the circuit board 220. The gear train 204 includes a shaft gear 305 that rotates the hollow main shaft 206, which as noted is press fitted or rigidly connected or indexed into the shaft gear 305. The gear train 204 further rotates an end gear 310 in a counter rotation direction to the shaft gear 305. The hollow main shaft 206 passes through the end gear 310 in a freely rotatably manner. The end gear 310 includes a gear nut 236 that sits into a lower post 238 defined on the lower annular band 122. As such, when the motor gear 300 rotates, the rotation causes the main shaft 206 to rotate in one direction and the lower annular band 122 to counter rotate.
The lower annular band 122 includes a center bore 254 sized to allow the hollow main shaft 206 is pass through and to rotate. The lower annular band 122 further includes an outer structural housing section 240 that includes diametrically opposed lower blade mounts 242 and apertures 243 in the housing section 240 above the mounts to accommodate for the connection to the lower propeller blades 130. Lower blade propeller caps 250 are positioned to secure an end of the lower propeller blades 130 to the lower blade mounts 242. The lower blade propeller caps 250 include a curved flange section 252 that flushes with the outer structural housing section 240 when positioned into place.
In addition, the lower annular band 122 includes a pair of opposed magnet holders 244 sized to receive magnet 246 used in concert with a hall effect sensor to monitor and in connection with a programming element stored on the circuit board is configured to control the RPM of the motor such that the motor can produce a near constant RPM regardless of the voltage from the power source, until the power source is virtually depleted. In one embodiment the magnet holders 244 are adjacent to the lower blade mounts 242.
As referenced above, hollow main shaft 206 is press fitted into the shaft gear 305. An upper end 311 of the hollow main shaft 206 is press fitted into an upper rotor drive coupler component 350. The upper rotor drive coupler component 350 includes a central hub 352 with a central hub bore 354 for accommodating the press fit onto the hollow main shaft 206. The central hub 352 includes a base section 356, a middle section 358, and a top section 340. The central hub may be a single unitary molded pieced or the sections may be separately configured and secured to each other.
The base section 356 includes four arms 360 radially extending from the base section 356 at equally positioned about 90 degrees from each other. Each arm 360 has an arm end 362 with an upwardly extending spacer element 364. The arm ends 362 are positioned against and secured to flanges 366 internally extending from the upper annular band 124, such that the arms are mountable to the upper annular band 124. In addition, the upper portion 132 of the housing structure 102 has four upper portion mounts 368 corresponding to the four spacer elements 364 on each arm 360 such that the upper annular band 124 can be secured to the upper portion 132 capturing the spacer elements 364 there between.
The middle section 358 of the central hub 352 is configured to mount the upper blades 144 to a pair of upper blade mounting structures 370. Each upper blade mounting structures 370 has a blade propeller mount 372 extending from one end that works in concert with an upper propeller blade cap 374 to capture and secure therebetween one of the upper blades 144. The body portion 376 includes an aperture 378 configured to mount onto a middle post 380 extending outwardly from the middle section. Each upper blade mounting structure 370 is further defined by having a body portion 376 extending away from the blade propeller mount 372 and towards the middle section 358 of the central hub 352. The body portion 376 has a first segment 382 extending away from the blade propeller mount 372 and a second segment 384 extending downwardly and further away from first segment 382. The second segment 384 leads into a connector segment 386. The connector segment 386 has the aperture 378 centrally located between first and second legs 388 that extend from the connector segment 386. One of the legs 388 is configured as a male leg while the other leg 388 is configured as a female leg. The male/female legs mirror each other such that when the pair of upper blade mounting structures 370 are aligned, the male legs fits into the female legs on either side of the post 380. In addition, one of the legs includes an outwardly facing upper blade mounting knob 390 (discussed in further detailed below). When assembled together, the legs and apertures (which are positioned on the post) allow the upper blade mounting structures 370 to pivot about the posts. However, since the female leg is larger than the male leg to accommodate the insertion thereof additional clearance on the arms 360 is required below the female legs. As such, the arm 360 positioned below the female leg has a channel 392 carved between the base section 356 and a support flange 394 on each arm 360.
The top section 340 of the central hub 352 is configured to mount the flybars 150. The pair of flybars 150 are mounted or extend from flybar hub 400. The flybar hub 400 has a hub bore 402 through the center to fit over the top section 340 and to allow the upper end 311 of the hollow main shaft 206 to pass there-through. The top section 340 further includes a pair of top posts 404 extending outwardly and configured to pivotally secure to hub points 406 by fasteners. In addition, extending from opposite areas 408 that are separately adjacent to the connection of the each flybar 150 to the flybar hub 400 are flybar hub mounting knobs 410. The top posts 404 are also offset from the middle posts 380 such that the flybars 150 are offset from the upper propeller blades 144.
Connecting the flybar hub mounting knobs 410 to the upper blade mounting knobs 390 are pivot links 420. The pivot links 420 (positioned on either side of the upper blade mounting structures 370) are configured to keep pivoting the flybars and upper propellers in closer alignment with each other to assist in the stabilization of the flying toy.
As noted above, the other end 214 (top end) of the rod 208 is rigidly secured to 430, while 136 connects to 430. This is configured by mounting a top cap mounting shaft 430 to the top end 214 of the rod. The top cap mounting shaft 430 extends through an opening 432 in the detent 134 of the upper portion 132 of the housing structure 102. The top cap 136 includes an opening 434 configured to secure the top cap mounting shaft 430 by a fastener (not shown).
The top cap 136 further includes at least one slot 440 sized to receive a corresponding flange 442 extending below the mounting base 138. Each of the corresponding flanges 442 includes a boss 444 such that the boss 444 can catch and secure under the slot 440 to secure the mounting base and thus the figurine 105 to the top cap 136.
Lastly, the mounting base 138 may include pedestals 446 to receive and secure a lower appendage of the figurine thereto.
As mentioned, one or more sensors 222 is in communication with a controller, defined by the circuit board 220. The one or more sensors 222 may include a transmitter and receiver pair which may operate with the controller to assist in detecting obstacles and/or surfaces. For example, the one or more sensors may include a lower infrared (IR) transmitter and a lower IR receiver. The lower IR transmitter, such as a light emitting diode, may be oriented to transmit a detection signal away from the flying toy 100 and toward an obstacle and/or surface such that the detection signal may bounce off the same. The lower IR receiver may be oriented to receive the detection signal when reflected off of the obstacle and/or surface under certain conditions. For example, the lower IR receiver may receive the reflected detection signal when the lower IR transmitter is within a predetermined range of distances from the obstacle and/or surface.
The controller 200 may be configured to adjust a speed of the motor in response to the IR receiver receiving the reflected detection signal. The controller may be further configured to adjust a speed of the motor in response to the lower IR receiver not receiving the reflected detection signal. The controller 200 may be further configured to adjust the speed of the motor or to deactivate the motor in response to receiving a motor voltage feedback signal indicating rotation obstruction of one or more of the propeller mounts. For example, in a crash scenario of the toy, an obstacle may prevent rotation of one of the propeller mounts which may result in motor voltage feedback identifiable by the controller. As such, the controller may deactivate the motor to prevent burnout of the motor and also to as a safety precaution for users. In another example, the toy may hover above the obstacle and/or surface as the controller adjusts the speed of the motor as multiple reflected detection signals are received.
Alternatively, the controller can be configured to enter different modes upon the receipt of specific signals from the IR receiver. For example, various hand gestures can be used to reflect the IR signal back to the receiver and pre-defined to cause the controller to enter a mode. In one example, a hand wave (back and forth hand gesture) under (or above) the flying toy can cause multiple bounce back signals within a predetermined time. The controller can be configured to control the flying toy to enter into a landing phase, powering the motor down slowing to cause the flying toy to land on a surface (such as the user's hand). In various scenarios, the controller could also control LED lights positioned in or around the flying toy? and can set the LED lights to various gestures provided by the user.
In another embodiment, multiple IR sensors/receiver pairs can be positioned around the flying toy to allow the toy to avoid obstacles and to recognize various hand gestures, such that a wave of a hand below the flying toy causes the toy to flicker lights and, while a wave of a hand at the side of the flying toy may cause the toy to flicker lights and move in a predetermined set of flying instructions. Lastly, the lights may be sent by the controller in various patterns and sequences randomly or predetermined and set off by gesturing.
In a final embodiment, the flying toy could also include safety arcs 500 positioned in front of the upper and lower propeller blades 130 and 144, configured to reduce injury to a user by rotating blades.
From the foregoing and as mentioned above, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the novel concept of the invention. It is to be understood that no limitation with respect to the specific methods and apparatus illustrated herein is intended or inferred.
