Abstract
A toy launcher that can launch the flying rings over 100 feet with a more stable trajectory and more accurate trajectory based on the ring and blade configuration. The toy launcher includes a magazine assembly in which a plurality of the flying rings can be loaded in an axial direction, aligned with a launch direction. The rings are rotated up to speed and launched via movement of a sliding handle in a first direction, and the next ring in the magazine is advanced to the launch position by a return movement of the handle.

[0071] The configuration of the ring 200′ shown in
[0072] Referring again to
[0073] Referring to
[0074] A pressure plate 36 is slidably mounted on the center tube 32. A spring 38 extends between the pressure plate 36 and a tube support 40 that is fixed to the housing 12. The tube support 40 supports the center tube 32 in a cantilevered manner.
[0075] As shown in
[0076] Referring to
[0077] Referring now to
[0078] As shown in detail in
[0079] In a preferred embodiment, the first gear is a bevel gear and includes two sets of teeth 91a, 91b, with the first set of teeth 91a adapted to be engaged by the gear rack 86 and the second set of teeth 91b being configured to be engageable with a second gear 92. The second gear 92 is a speed increasing gear and includes a first set of teeth 92a that are adapted to engage the second set of teeth 91b of the first gear 91, as well as a second set of teeth 92b, preferably having a 2:1 ratio to the first set of teeth 92a of the second gear 92. A third gear 93 is provided that is also a speed increasing gear and includes a first set of teeth 93a that are engaged to the second set of teeth 92b of the second gear 92, as well as a second set of teeth 93b that engage with the last gear 94 that is attached to the drive spindle 72. This gear train 90 preferably provides a speed increase from the first gear 90 to the last gear 94 of at least about 3:1 and more preferably in the range of 5:1 to 6:1. However, other gear ratios can be provided. Additionally, the number of gears in the gear train 90 could also be varied. The second and third gears 92, 93 are supported on a fixed axis of rotation, preferably u a gear shaft or other support. The fourth or last gear 94 is fixed to the drive spindle 72, which is preferably supported by a bearing surface in an area of the gear train 90, and may also be supported by a further bearing in the center tube 32 at or near the discharge end. The bearing surfaces may be formed from the plastic material of the housing or other components.
[0080] Further, as shown in detail in
[0081] Referring to
[0082] Referring to
[0083] Referring to
[0084] In order to prevent frictional losses to the force transmitted via the drive assembly 80 to the drive spindle 72, preferably the spring biased positioning stop 106 is moved out of contact with the spindle alignment cam 100 as the drive assembly 80 is activated. In the preferred embodiment, an actuator arm 120 that is slideably moveable in the housing 12 via movement of the catch actuator plate 54 engages with the spring biased positioning stop 106 and moves the spring biased positioning stop 106 to a disengaged position as the catch actuator plate 54 moves in the first direction X1 to the rear position as the handle 82 is initially moved from its front-most position near the discharge end 16 in the first direction X1. The actuator arm 120 also has limited travel which is provided via slotted mounting holes 122a, 122b. The actuator arm 120 can move with the catch actuator plate 54 in both directions by a direct connection or can be spring biased in the second direction X2 toward the discharge end and be moved in the first direction X1 by contact with a surface of the catch actuator plate 54. Preferably, the actuator arm 120 includes a ramp surface 124 that engages a corresponding ramp surface 108 on the spring biased positioning stop 106.
[0085] In use, a user can load flying rings 200, 200′ into the magazine assembly 30 by sliding them with the drive pin(s) 206a, 206b aligned with the slot(s) 76a, 76b in the drive hub 74 and on to the center tube 32 with the drive pin(s) 206a, 206b being received in the axially extending groove(s) 34a, 34b. The insertion movement presses the discharge catch 50 as well as the advancing catch 60 downwardly against the forces springs 51, 61, respectively, in order to allow loading. A plurality of the rings 200, 200′ can be inserted with the force of insertion pressing back the pressure plate 36 against the force of the spring 38. In a preferred embodiment, 10 of the rings 200, 200′ can be located into the magazine assembly 30.
[0086] For launching, a user moves the handle 82 in the first direction X1 from its forward position, resulting in the discharge catch 50 being moved from the holding position to the release position via the discharge catch release 52, which is preferably located on the catch actuator plate 54. As the user continues to move the handle 82 in the first direction X1 to its rear-most position, the gear rack 86 presses the first gear 91 of the gear train 90 into contact with the second (or next) gear 92, creating the rotational movement of the gear train 90 which is transmitted to the last gear 94 that is fixed onto the drive spindle 72. The drive spindle 72 rotates the drive hub 74 affixed at or near the discharge end 16 along with the flying ring 200, 200′ that is in the launch position L on the drive hub 74. This rotational movement is transmitted via the slot(s) 76a, 76b, and preferably the recesses 77a, 77b in the slot(s) 76a, 76b, to the drive pin(s) 206a, 206b on the ring 200, 200′ in the launch position L which is rotated to a high speed. When the handle 82 reaches the rear most position, the drive spindle 72 stops and the rotational inertia of the ring 200, 200′ in the launch position causes the drive pin(s) 206a, 206b to move out from the recesses 77a, 77b and down the curved release profiles 78a, 78b on the opposite side of the slot(s) 76a, 76b from the recesses with the blades 210a - 201c causing the ring 200, 200′ to accelerate from the discharge end 16 of the toy launcher. Using this arrangement, the rings 200, 200′ can travel 100+ feet with high flight stability.
[0087] Return movement of the handle 82 causes the discharge catch release 52 to move from the release position such that the discharge catch 50 is moved back to the holding position via the spring 51. At the same time, the advancing catch release 62 is activated to move the advancing catch 60 to a loading position in which a next one of the rings 200, 200′ in the magazine assembly 30 is moved to the launch position L via pressure from the spring 38 acting against the pressure plate 36. Once the next ring 200, 200′ is in the launch position L, the advancing catch release 62 allows the advancing catch 60 to return to the holding position from the loading position.
[0088] Having thus described the presently preferred embodiments in detail, it is to be appreciated and will be apparent to those skilled in the art that many physical changes, only a few of which are exemplified in the detailed description of the invention, could be made without altering the inventive concepts and principles embodied therein. It is also to be appreciated that numerous embodiments incorporating only part of the preferred embodiment are possible which do not alter, with respect to those parts, the inventive concepts and principles embodied therein. The present embodiments and optional configurations are therefore to be considered in all respects as exemplary and/or illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all alternate embodiments and changes to this embodiment which come within the meaning and range of equivalency of said claims are therefore to be embraced therein.
