Definitions

  • the present invention relates to an apparatus for moving an object, and in particular, but not exclusively, to an apparatus for use in moving an object and forming part of a plaything.
  • objects such as signs or the like may be permitted to display a greater number of images, icons, illustrations or the like if they are moved or manipulated in a particular manner, than could be available should the sign be held stationary.
  • a known 'magic' trick can be performed by skilled performers by drawing a first arrow on one side of a piece of card and a second arrow on the reverse side of the card.
  • the card can be rotated around different axes to present a variety of different orientations of the arrows to an audience.
  • Figures 1a, 1b and 2 A diagrammatic representation of the performance of this trick is shown in Figures 1a, 1b and 2, reference to which is now made.
  • Figures 1a and 1b show the front and back of a piece of card 10, each side displaying an arrow 12, 14, which are orientated at 90 degrees with respect to each other.
  • Figure 2 shows a performer's left and right hands 16, 18 which rotate the card 10 around a diagonal axis 20.
  • the arrow 14 on the reverse side which in this example is originally pointing in an upwards direction, will be rotated by 90 degrees so that when it is presented to the front, it will appear in the same orientation as the arrow 12 when said arrow 12 was originally presented to the front.
  • Continued rotation of the card 10 about this axis 20 will thus result in the arrows 12, 14 consistently pointing in the same orientation when presented to the front.
  • the performer typically narrates the movement of the card 10 with an amusing story, during which the performer changes the axis of rotation by moving his hands 16, 18 to rotate the card around the other diagonal axis 22. This results in the arrows 12, 14 being presented to the audience in one orientation and then another, in this case from orientated right then orientated left, then right, and so on.
  • an apparatus for moving an object about separate axes of rotation comprising:
  • the first driven member may be adapted to be permanently rotatably coupled to the rotary drive means.
  • the first driven member may be adapted to be selectively rotatably coupled to the rotary drive means.
  • the second driven member may be adapted to be permanently rotatably coupled to the rotary drive means.
  • the second driven member is adapted to be selectively rotatably coupled to the rotary drive means.
  • control means may be adapted to rotatably couple the first and second driven members alternately to the rotary drive means. This arrangement will accordingly result in rotation of the object about one axis of rotation at any one time.
  • control means may be adapted to rotatably couple the first and second driven members to the rotary drive means simultaneously. Accordingly, this arrangement may permit simultaneous rotation of the object about the first and second axes of rotation.
  • the first driven member comprises a mounting arrangement adapted to support the object. Accordingly, when the first driven member is rotatably coupled to the drive means, and the drive means is activated, the mounting arrangement will be caused to rotate about the first axis of rotation, thus resulting in the object supported thereon also being rotated about said first axis of rotation.
  • the rotary drive means comprises a drive shaft.
  • the control means may be adapted to selectively rotatably couple the first and second driven members to the drive shaft to cause the required rotation of the object about the first and second rotational axes.
  • the second driven member is carried by the first driven member, and more particularly by the mounting arrangement of the first driven member.
  • the object is secured to the second driven member. Accordingly, in this arrangement the object is mounted on the mounting arrangement of the first driven member via the second driven member.
  • At least one of the first and second driven members may be hollow. This may, for example, permit electrical cabling, fibre optic cabling or the like to be passed therethrough. This may permit the object to be illuminated or alternatively permit transmission of power or electrical signals through the member.
  • the object may comprise translucent and/or opaque regions. Accordingly, the object may selectively project a display onto or through the object, for example but not exclusively to provide a backlit display or to project onto a wall, ceiling or the like.
  • the second driven member comprises a secondary drive shaft.
  • the secondary drive shaft is secured to the object such that rotation of the secondary drive shaft causes corresponding rotation of the object.
  • the secondary drive shaft is adapted to be rotatably coupled to the rotary drive means via a rotary transmission means.
  • the rotary transmission means comprises a gear train.
  • the rotary transmission means may comprise a rack and pinion gear mechanism, belt or chain drive mechanism or the like.
  • the second driven member may be driven by its own rotary drive means, such as a motor adapted to selectively rotate the second driven member to rotate the object about the second axis of rotation.

  • said lever mechanism may be adapted to securely engage the rotary drive means when rotation of the object is required about the first axis of rotation.
  • the lever mechanism may be adapted to disengage the rotary drive means when rotation of the object is required about the second axis of rotation.
  • the lever mechanism may be adapted to disengage the rotary drive means and engage a fixed structure to secure the first driven member against rotation, such that rotation of the rotary drive means is advantageously transmitted to rotation of the second driven member carried on the first driven member.
  • the fixed structure may be a housing of the apparatus, such as a casing or frame or the like.
  • the lever mechanism may be actuated by an electromagnet switching arrangement or the like.
  • control means may comprise locking means to selectively secure the second driven member to the rotary drive means.
  • the locking means may be adapted to selectively secure the second driven member to the rotary drive means via the mounting arrangement of the first driven member.
  • the locking means may be adapted to engage the mounting arrangement to permit rotation of the object about the first axis of rotation when the first driven member is rotated.
  • the control means may further comprise torque storage means, such as a torsion spring.
  • torque storage means such as a torsion spring.
  • the torque storage means is adapted to be secured between the rotary transmission means and the second driven member. Accordingly, in this arrangement, when the locking means is engaged, the second driven member will be rotationally constrained relative to the first driven member.
  • rotation of the first driven member transmits rotation to the torque storage means via the rotary transmission means.
  • rotation of the torque storage means permits rotational potential energy to be stored in the storage means.
  • the locking means may be disengaged. Accordingly, the torque stored in the torque storage means may be released to rotate the second driven member to rotate the object about the second axis of rotation.
  • control means may be adapted to rotatably couple the rotary drive means to the first driven member for a duration sufficient to permit a predefined angle of rotation of the object about the first axis to be achieved.
  • control means may also be adapted to rotatably couple the rotary drive means to the second driven member for a duration sufficient to permit a predefined angle of rotation of the object about the second axis to be achieved.
  • control means is adapted to rotatably couple the rotary drive means to the first and second driven members alternately at a frequency selected to permit intermittent rotation of the object about the first and second axes by predetermined angles of rotation. Accordingly, the control means when operating in this manner will permit the object to be rotated by a predetermined angle of rotation about the first axis, and then subsequently permit the object to be rotated by a predetermined angle of rotation about the second axis.
  • control means is adapted to be operated automatically.
  • control means may be adapted to be manually operated, for example by an user.
  • the apparatus further comprises a motor coupled to the rotary drive means to cause rotation thereof.
  • the apparatus comprises variable speed control means adapted to selectively vary the angular velocity of the rotary drive means.
  • the variable speed control means may be adapted to vary the angular velocity of the rotary drive means in accordance with, for example, the selection of which of the first and second driven members is rotatably coupled thereto.
  • the variable speed control means is adapted to decrease the angular velocity of the rotary drive means when rotatably coupled to the first driven member, and to increase the angular velocity of the rotary drive means when rotatably coupled to the second driven member. Accordingly, in this particular arrangement, the object will be rotated about the second axis of rotation at a greater angular velocity than about the first axis of rotation.
  • the variable speed control means may alternatively be adapted to cause the object to rotate faster about the first axis of rotation than the second axis of rotation.
  • variable speed control means may be adapted to cause the driven members to be rotated in one direction of rotation about the first and second axes.
  • the variable speed control means is adapted to cause the first driven member to rotate in reverse directions of rotation about the first axis of rotation. Accordingly, the object may be moved to both oscillate and rotate about the first axis of rotation.
  • the variable speed control means may be adapted to cause the second driven member to rotate in reverse directions of rotation about the second axis of rotation.
  • variable speed control means may comprise a variable speed motor.
  • Electronic control circuitry may be provided to control the variation of the speed of the motor.

  • the second frame may comprise a pinion gear wheel secured thereto and mounted about a pivot axis of the second frame, wherein the pinion gear wheel is adapted to engage a reciprocating rack.
  • the rack is coupled to the first shaft via a crank pin arrangement. Accordingly, rotation of the first shaft will provide a reciprocating drive to the rack via the crank pin.
  • the object is adapted to display at least a first image and a second image, wherein the orientation of said first and second images are manipulated by movement of the object about said axes of rotation.
  • the control means of the present invention may be adapted to display the first and second images in a predetermined sequence of orientations by selectively causing rotation of the object about the first and second axes of rotation.
  • the object may be adapted to be rotated about a third axis of rotation.
  • the third axis of rotation is perpendicular to the first and second axes.
  • the third axis projects in the z-direction.
  • rotation of the object about the third axis may be achieved by rotation of the mounting arrangement of the first driven member about the third axis.
  • the mounting arrangement may be adapted to be rotated by a rack and pinion gear mechanism.
  • the rack and pinion gear mechanism may be curved to maintain the radial distance between the pinion and the object.
  • the object may be rotated or oscillated about the centre of the object such that a viewer would be unaware of the change in orientation.
  • rotation or oscillation of the object about the third axis and rotation of the object about the second axis is simultaneous.
  • the rotation about the third axis of rotation advantageously disguises rotation of the object about the second axis such that a viewer is unaware of the change in orientation.
  • the housing of the apparatus may be configured to disguise the change in direction.
  • the viewer may be permitted to see the rotation of the object about the third axis of rotation and will be interested by the moving display that is observed.
  • the apparatus of the present invention is adapted for use in a plaything which comprises an object adapted to display at least a first image and a second image, wherein the orientation of said first and second images are manipulated by movement of the object about said axes of rotation.
  • the apparatus may be adapted to display all orientations of the images, for example but not exclusively arrows, in the same direction. Accordingly, the viewer or audience located at one viewing angle is shown all orientations of the images in order to observe the apparent visual illusion.
  • the object may comprise a piece of card or other substantially planar body.
  • the object may comprise a spherical or cube type body or the like.
  • a plaything comprising:
  • FIG. 3 of the drawings a first portion of an apparatus 30 for use in a plaything.
  • the apparatus 30 comprises a fixed main frame 32 defining a platform 34 and an aperture 36 therein, through which aperture 36 a spherical body 38 protrudes.
  • the spherical body 38 includes two arrows 40, 42 displayed on diametrically opposed surface portions of the body 38. In the embodiment shown the arrows 40, 42 are orientated at 90 degrees with respect to each other.
  • the apparatus 30 of the present invention is adapted to rotate the spherical body 38 alternately about axes 44, 46 which are disposed at 45 degrees relative to each other.
  • the desired effect is such that rotation of the spherical body 38 about vertical axis 44 will maintain the arrows 40, 42 in the orientations shown, and rotation of the body 38 about the inclined axis 46 will cause the arrows 40, 42 to change orientation.
  • rotation of the body about axis 46 by 180 degrees will result in the arrows 40, 42 pointing in opposite directions.
  • the spherical body 38 is adapted to be rotated or oscillated about vertical axis 44, giving an audience sufficient time to view the orientation and movement of the arrows 40, 42.
  • the speed of rotation is increased to a level which would be difficult to detect with the eye, creating the illusion of an instantaneous direction change of the arrows 40, 42.
  • the body 38 may then once again be slowly oscillated about the vertical axis 44, presenting the new orientation of arrows 40, 42 to the audience.
  • the use of a spherical body 30 assists in providing the desired effect as this disguises the change in the axis of rotation.
  • mirrors may be incorporated to further intrigue and entertain the audience.
  • a rotating frame 48 and a drive shaft 50 Positioned below the platform 34 is a rotating frame 48 and a drive shaft 50 which extends into the rotating frame 48 and is aligned with the vertical axis 44.
  • the drive shaft is rotatably supported by bearings 52, 54 which are mounted on the main frame 32.
  • the rotating frame 48 includes a rotating shaft 56 rotatably mounted on the fame 48, wherein the spherical body 38 is mounted on said shaft 56. Accordingly, the arrangement is such that rotation of the rotating frame 48 results in rotation of the spherical body 38 about the vertical axis 44, and rotation of the rotating shaft 56 results in rotation of the body 38 about the inclined axis 46.
  • the drive shaft 50 includes a gear wheel 58 secured thereto, and the rotating shaft 56 includes a gear wheel 60 secured thereto, wherein the gear wheels 58, 60 are rotatably engaged via an intermediate idle gear wheel 62 mounted on a shaft 64 secured to the frame 48.
  • a lever 66 is pivotally mounted on the rotating frame at pivot point 68 and is caused to pivot about point 68 by an electromagnet device 70, such as a solenoid, reciprocating an operating arm 72.
  • the lever 66 is adapted to be pivoted between two positions: a first position in which the lever 66 is engaged with gear wheel 58, and thus drive shaft 50, via a clutch plate 74; and a second position in which the lever 66 is disengaged from the gear wheel 58 and engaged with the main frame 32. Accordingly, when in the first position the lever 66 causes the rotating frame 48 to become rotatably coupled to the drive shaft 50, such that rotation of the drive shaft 50 causes rotation of the frame 48 and thus body 38 about axis 44.
  • the lever 66 As the lever 66 is engaged with the gear wheel 58 in this first position then no rotary transmission to the rotating shaft 56 is permitted.
  • the lever 66 When in the second position the lever 66 causes the rotating frame 48 to become fixed to the main frame 32, preventing frame 48 from rotating, which in turn permits gear wheel 58 to drive gear wheel 62, which in turn drives gear wheel 60 to effect rotation of the spherical body 38 about axis 46.
  • the electromagnet device 70 is controlled by a controller 76 in order to alternate rotation of the body 38 about each axis 44, 46 in the desired manner.
  • the lever 66 is biased towards the first position by way of an over-centre spring 78.
  • the drive shaft 50 is caused to be rotated by a motor (not shown) via a variable speed mechanism, shown in Figures 4 and 5.
  • the variable speed mechanism is adapted to cause the drive shaft 50 to rotate at a lower rate when the body 38 is to be rotated about the vertical axis 44, and at an increased rate when the body 38 is to be rotated about the inclined axis 46.
  • the variable speed mechanism is adapted to cause the body 38 to be oscillated about the vertical axis 44, i.e., cause reverse rotation.
  • the variable speed mechanism will now be described with reference to Figures 4 and 5.
  • the variable speed mechanism incorporates a reverted epicyclic wheel train, described below.
  • the mechanism includes a fixed frame 82 and a pivoting or epicyclic frame or arm 84 pivotally mounted to the first frame 82.
  • the drive shaft 50 extends through both the epicyclic arm 84 and the fixed frame and provides the pivot connection therebetween.
  • Mounted on the fixed frame is a rotating crank shaft 86, and mounted on the epicyclic arm is a shaft 88.
  • the drive shaft 50, crank shaft 86 and shaft 88 carry a number of gear wheels which are adapted to transmit and vary rotary motion from a motor (not shown) to the drive shaft 50.
  • a motor drives gear wheel 90 which is rigidly mounted on the crank shaft 86, which shaft 86 is accordingly rotated.
  • Gear wheel 90 engages and drives gear wheel 92 which is freely mounted on the drive shaft 50.
  • gear wheel 94 which engages and drives gear wheel 96.
  • Gear wheel 96 may be rigidly secured to shaft 88 which will thus also rotate, or alternatively may be freely mounted on the shaft 88.
  • Gear wheel 98 is rotatably fixed to gear wheel 96 and is therefore rotated therewith.
  • Gear wheel 98 engages and rotates gear wheel 100 which is rigidly fixed to the drive shaft 50, causing said shaft 50 to be rotated.
  • the specific gear ratio across the resulting gear train of the mechanism 80 may be selected in accordance with the required output speed of the drive shaft 50.
  • the crank shaft 86 is adapted to be rotated at twice the average speed of the drive shaft 50.
  • a pinion gear wheel 102 is secured to the epicyclic arm 84 and is mounted about drive shaft 50, wherein the pinion gear wheel 102 is adapted to engage a reciprocating rack 104.
  • the epicyclic arm 84 is shown in its central position.
  • the rack 104 is coupled to the crank shaft 86 via a crank pin 106 which engages a slot 108 defined in an end portion of the rack 104. Accordingly, rotation of the crank shaft 86 will provide a reciprocating drive to the rack 104 via the crank pin 106 and slot 108. In this way, one full rotation of the crank shaft 86 will cause the epicyclic arm 84 to be pivoted side-to-side once.
  • the rate of pivot of the shaft will be greater that the rate of rotation of gear wheel 98.
  • the lever 66 ( Figure 3) is advantageously positioned by the electromagnet device 70 and controller 76 ( Figure 3) to cause the rotating frame 48 ( Figure 3) to rotate, resulting in the body 38 being rotated, or indeed oscillated due to the reverse rotation of the drive shaft 50, about the vertical axis 44.
  • the epicyclic arm 84 will be caused to pivot in a second, opposite direction, causing gear wheel 98 to 'walk' around gear wheel 100 in a reverse direction, resulting in an increase in the speed of the drive shaft 50.
  • the lever 66 ( Figure 3) is advantageously positioned by the electromagnet device 70 and controller 76 ( Figure 3) to secure the rotating frame 48 and cause the shaft 56 ( Figure 3) to rotate, resulting in the body 38 being rotated at the increased rate, about the inclined axis 46.
  • FIG. 6 An alternative embodiment of the present invention is shown in Figure 6 in which like components are indicated by like numerals incremented by 100.
  • a frame 148 is coupled to and rotates with a first drive shaft 150, the shaft 150 orientated on a vertical axis 144.
  • a second driven shaft 156 orientated on a second axis 146, is supported by bearings 102, 104, mounted in the frame 148.
  • the second shaft 156 supports a spherical body 138, the second shaft 156 comprising a disc or arm 106 which permits the frame 148 to be locked to the second driven shaft 156 for approximately one full rotation of the shaft 150. This may be achieved via a solenoid arrangement or alternativeiatively by an electromagnet selectively engaged at the appropriate time to lock the frame 148 to the second driven shaft 156.
  • a fixed wheel or gear 158 on the first driven shaft 150 engages and rotates a second wheel or gear 160 freely rotatably mounted on the second driven shaft 156.
  • a torsion spring 108 is mounted on the second shaft 156 and is located within a barrel or drum 110 fixedly mounted to the second gear 160.
  • a support arm 112 is fixed to the second shaft 156 to assist in balance and support of the second gear 160 on the shaft 156.
  • the spring 108 is fixed at one end to the second gear 160 via the barrel 110 and at the other end to the second shaft 156 via the arm 112.
  • the arm 112 provides a fixing point such that rotation of the second gear 160 relative to the shaft 156 rotates or winds the spring to permit torque energy to be stored as potential energy. More than one spring 108 may be provided to improve the balance of the second shaft 156 and second driven gear 160.
  • the first shaft 150 rotates through one revolution, causing the fixed gear 158 to rotate the larger gear 160.
  • the second gear 160 is free to rotate on the second shaft 156, rotation of the first drive gear 158 dues not cause direct rotation of the body 138 via the second gear 160.
  • the body 138 is thus rotated one revolution about the first axis 144.
  • the second gear 160 is twice the diameter of the smaller fixed gear 158 and rotates 180 degrees in a counter direction for one rotation of the smaller fixed gear 158. Rotation of the second gear 160 builds a torque in the form of a rotational returning force, in the spring 108.
  • This stored torque is equivalent to 180 degrees of rotation of the shaft 156 and is released once per revolution of the shaft 150 about the first axis 144 when the disc 106 engages a trigger or switch (not shown).
  • the disc 106 On engaging the trigger, the disc 106 disengages the shaft 156 from the frame 148 permitting the shaft 156 to rotate the spherical body 138 about the second axis 146.
  • Rotation of the shaft 156 is driven by the release of stored torque energy in the spring 108. The result is 180 degree rotation of the second shaft 156 about the second axis 146.
  • the spherical body 138 includes two arrows 140, 142 displayed on diametrically opposed surface portions of the body 138, the arrow 140 pointing in a downwards direction and the second arrow 142 pointing to the right, the movement of the spherical body 138 results in a sequence of arrows 140, 142 down-right-up-left.
