DETAILED DESCRIPTION

(11) FIGS. 1 and 2 shows an embodiment of a toy device for dispensing stackable or rollable materials, which in this example takes the form of cards, such as playing cards.

(12) The device 10 comprises a housing 12 that generally acts to encase partially or fully and/or support and position at least some other components of the device. As will be described below in more detail in relation to FIGS. 3 to 9, the device 10 also has a release mechanism 60 and an actuation mechanism 80.

(13) In this example the housing 12 is a two piece plastics housing that joins along a vertical plane 14 of the device using screw fasteners 16. It will be appreciated that other suitable forms for manufacturing the housing may be employed.

(14) In this example, the device is shaped in a gun-like form. The housing 12 provides a handle portion 18 by which the device may be held in the hand by a user. This may be provided with a grip surface or over moulded with a rubber grip as required. The housing 12 also has a trigger surround portion 20 positioned such that a trigger 30 within the trigger surround portion 20 as part of a release mechanism 80 (shown below) can be actuated by the user's finger when holding the device by the handle portion 18.

(15) The housing also has a main body portion 22 atop the handle portion 18 which contains a firing cavity 40 (shown in FIG. 3) in which the chartaceous materials are stowed, and elements of the actuation mechanism 80 and a release mechanism 60 (described below). The top surface of the body portion has a lid 24 which is movable to allow access to the firing cavity to allow materials to be loaded to the device. In the present example, the lid 24 has pivoted connections 26 to the main body of the housing at the rear. A biasing arm 27 is provided below the lid also having a pivoted connection 27a to the main body of the housing at the rear and an upwardly projecting tab 28 which extends through an aperture 25 in the top surface of the lid 24. Thus, the user can pull on the tab 28 allowing the lid 24 and arm 27 to be lifted for gaining access to the firing cavity 40 to load the device. As shown in FIG. 3, the biasing arm can pivot down inside the firing cavity 40 to provide a compressive force to the stack of cards in the firing cavity 40, through its own weight and/or through the biasing force of a spring (not shown).

(16) The device has a crank 62 which projects from a side of the main body portion 22 as part of the actuation mechanism 60. As will be described, with the crank turned 62 by the free hand of the user, depressing the trigger 30 causes cards to be dispensed from the body 22 of the device via an aperture 30 at the front of the device 10.

(17) FIG. 3 shows the device 10 with half of the housing removed on the side of the crank 82 showing the activation mechanism 80 and release mechanism 60 inside. FIGS. 4A and 4B show the activation mechanism 80 and release mechanism 60 in isolation from reverse angles. The activation mechanism 80 comprises the crank 82 which turns a drive wheel 84 via a gear train 86 contained in a gear casing 88. FIG. 5 shows the activation mechanism 80 without the gear casing 88 showing the gear mechanism 86. A gear ratio of between 10× and 30× may be used to achieve desired dispensing speeds, e.g. 0.5 to 3 m/s via moderate hand cranking of the device, e.g. 0.5 to 3 revolutions/s with a moderate sized drive wheel (e.g. 1.5 cm diameter). A slip clutch (not shown) may be provided in the gear train 86 to prevent over cranking causing damage to the gear train.

(18) The gear casing 88 is arranged to pivot in the housing 12 of the device 10 about the axis 87 about which the crank 82 rotates. To achieve this, the gear casing 88 may have pivot features, e.g. cylindrical projections/axles, on either side aligned with the axis 87. These cylinders 90,92 are received by holes or other suitable shaping in the housing 12 (not specifically shown) of the device, such that the gear casing 88 can pivot about the cylinders 90,92. The crank shaft passes through the cylinder on one side into the gear casing 88 so that the gear casing 88 is free to pivot whether or not the device is being cranked.

(19) The drive wheel 82 may be provided with a friction surface, e.g. rubberised, the upper surface of which protrudes into the firing cavity 40 through an aperture 42 in the bottom wall 44 of the firing cavity 40 provided by the housing 12 when the gear casing 88 is pivoted in a first position. Thus, the bottom most card in the cavity 40 rests on the upper surface of the drive wheel in this position, and as the crank is turned the drive wheel acts to urge the bottommost card towards the front aperture to dispense the card. As described below, the gear casing 88 can be pivoted to a second position where the drive wheel 82 is withdrawn from the cavity 40 so as not to make contact with the cards.

(20) The release mechanism 60 comprises the trigger 62 connected to a lever 64 at the end of which is an upwardly projecting stop 66. The lever 64 is pivoted 66 to the housing 12 such that the trigger portion 62 is accessible to a user in the trigger surrounding portion of the housing and the stop 66 is positioned in the path between the firing cavity 40 and the aperture 30. Depressing the trigger moves the stop 66 downwards and out of the path.

(21) As shown in FIG. 4B, the trigger 62 also operates to pivot the gear casing 88 into the first position by a surface 67 of the trigger arm 64 engaging a projection 94 at the back of the gear casing, so as to depress the rear of the gear casing and via the pivot 90,92 raise the front of the gear casing and drive wheel to engage the cards. As shown in FIG. 4A, the gear casing 88 has a projecting stop 96 which bears against a surface of the trigger arm 64 as the trigger 62 is depressed, thus providing a limit to the amount the gear casing can pivot and so precisely controlling the position of the drive wheel in the card engaging position when the trigger is depressed.

(22) The trigger 62 may be depressed against the bias of a spring (not shown) to return the release mechanism 60 to the non-activated position when the trigger is released. Alternatively or additionally, depressing the trigger 62 to pivot the gear casing 88 may work against the weight of the gear casing and other components of the actuation mechanism 80, which create a moment to return the release mechanism to the non-activated position when the trigger is released. The direction in which the crank is turned to dispense cards may also be selected such that forces arising through the interaction of the mechanism with the gear casing tends to pivot the gear casing to the non-activated position, so as to avoid the possibility of cranking the device inadvertently operating the release mechanism.

(23) FIGS. 6 and 7 show a card being dispensed by the device. Initially, as shown in FIG. 6, a stack of cards 100 are loaded into the firing cavity 40 as previously described. The biasing arm 27 provides a compressive force 86 to the top card, preferably close to the drive wheel 84. In the neutral position of the release mechanism 60, the stop 66 is positioned in the path between the bottommost card 110 and the aperture 30 in the housing 12 to prevent cards from passing through the aperture 30 until the device is triggered, and the gear casing is pivoted such that the drive wheel 84 is positioned below and out of contact with the bottommost card 110. The user begins the turn 200 the crank 82 to bring the drive wheel 84 up to speed, whilst in this position it does not contact the bottommost card 110.

(24) As shown in FIG. 7, the user then activates the release mechanism 60 by depressing 210 the trigger 62. The lever 64 pivots the release mechanism 80 such that the drive wheel 84 makes contact (212) with the bottommost card 110 and pivots (211) the stop 66 out of the way, freeing the bottommost card 110 to be driven out of the dispensing aperture 30 by the drive wheel 84. The biasing arm 27 (not shown for clarity) helps keep good contact between the cards and the drive wheel such that the required frictional force can develop to drive the cards.

(25) Once the bottommost card 110 is past the drive wheel 84 and substantially out of the aperture 30, the new bottommost card then comes into contact the drive wheel 84 and begins to be driven out of the aperture 30, and so on. The drive wheel 84 is preferably positioned toward the front of the cavity 40 so that one card 110 is out or nearly out of the firing cavity 40 before the next card from the stack 100 comes into contact with the drive wheel 84. Thus, a quick succession of cards 110 can be dispensed as long as the trigger 62 is depressed at a speed that is readily controllable by the user by way of the hand crank 82. Alternatively a single cards 110 can be dispensed at a time.

(26) Thus, the device 10 provides a simple mechanical way of dispensing one or more cards in a continuous stream with fine control of the speed and release of the cards.

(27) To further simplify the mechanism, the stop 66 could be removed, at the risk of cards falling out of the device if pointed downwards. Alternatively, a different mechanism could be used to move the drive wheel into contact with the cards when the trigger is depressed, e.g. the casing or drive wheel could be made to slide, etc. In some examples, the drive wheel 84 may not move at all, but will be permanently in contact with the cards. The frictional properties of the drive wheel 84 may be carefully chosen in conjunction with any biasing force 86 to allow slip between the wheel 84 and the card 110 whilst the stop 66 holds the card 110 in place, but to drive the card 110 out of the device when the trigger 62 is depressed moving the stop 66.

(28) In the above examples, the weight of the biasing arm 27 helps give rise to the necessary frictional force with the drive wheel 84 to drive the cards. Alternatively, an additional biasing force may be employed (not shown), for instance an additional weight, the weight of the lid, or a resilient biasing element bearing on the topmost card in the stack 100 or any combination thereof to help create the desired frictional force between the material and the drive wheel 84. In other examples, the weight of the card or cards in the stack 100 alone may be sufficient to develop the necessary frictional force with the drive wheel 84.

(29) In other examples, the activation mechanism 80 may include a spring which is wound up by the crank 82. A ratchet may be provided to prevent the spring unwinding through the crank 82 and instead releasing energy through to the drive wheel 84. Thus, the user may crank the device 10 to the desired speed corresponding to the amount of energy stored in the spring, stop cranking the device before releasing cards whilst the spring continues to deliver energy to the driving wheel 84. Alternatively or additionally, a flywheel can be added to the activation mechanism 80 to store energy to again allow the user to stop cranking the device before releasing cards. For instance, it is anticipated that the main components of the device 10 will be manufactured from plastics material, a metal flywheel may be coupled to the drive wheel or included in the gear mechanism.

(30) In other examples, instead of a rotating crank, a lever driven mechanism may be used. Gearing may translate linear or rotational movement of the lever to a spring, which is arranged to drive the drive wheel. In principle, any mechanism for converting manual input from a user to rotate the drive wheel 84 can be used. In other examples, instead of a trigger, a button or other actuator can be provided to actuate the release mechanism.

(31) A further example, as shown in FIG. 8, is similar to that of FIG. 1 but has an adaptor 29 for small materials which may be clipped-in or otherwise removably attached to the device in the firing cavity 40 to adapt the firing cavity 40 by way of its size, shape and/or position in the firing cavity to position and align a stack of smaller material, e.g. notes, cards, etc., than would fit in the firing cavity 40 without the adaptor. The adaptor 29 positions the smaller materials so they reach the driving wheel. Thus, by providing one or more different adaptors or allowing the adaptor to clip in to the cavity in different positions, the device can be made to work with a variety of sized materials.

(32) The mechanism may be used to dispense a stack of paper tokens, leaflets, bank notes, cards, or any relatively thin, stackable items.

(33) In other examples, the mechanism may be used to dispense chartaceous material from a roll instead of a stack. For example, as shown in FIG. 9, the firing cavity is adapted to hold a roll of material 110 and allow it to rotate, whilst maintaining the bottommost surface of the roll in contact with the driving wheel. In the present example, the device has a rotatable axle or spindle 24 mounted to the housing 12 for holding the reel of material 110. The housing 12 or lid 24 may be provided with suitable cut-outs to accommodate the reel of material 100. The free end of the material 112, where it winds off the reel, is fed to the driving wheel 84 and maintained taut, so that it makes sufficient contact with the driving wheel 84, by biasing arm 27, which in this example is pivoted at one end to the housing 12 at the front of the device 10 and makes contact with the material 100 at the other end close behind the driving wheel 84. The device 10 could further include a tear-off feature adjacent the aperture 30 to aid the user in tearing off the material once a portion has been dispensed. For instance, a sharp or toothed edge 32 can be provided to help mechanically sever the material when the material is pulled down over the edge 30. Thus, the user can dispense tapes, ribbons, streamers, etc. by cranking the device and depressing the trigger as described above in relation to the example of FIG. 1.

(34) The described example is a hand held device. However, the device could alternatively be adapted to rest on a table or other surface, or have attachment fixtures for attaching to any other desired object. The housing is therefore not constrained to having a handle, but can take many forms according to the application and desired type of use of the device.

(35) Embodiments of the present invention have been described with particular reference to the example illustrated. However, it will be appreciated that variations and modifications may be made to the examples described within the scope of the present invention.
