Description
BACKGROUND OF THE INVENTION
The present invention relates to a flying device adapted to be
thrown in a spinning motion.
Recreational saucer type of devices (such as a FRISBEE) which are
adapted to be thrown in a spinning fashion and which display a
"floating" aerodynamic property are well known and have become very
popular. Similarly, devices such as flying saucer toys of which U.
S. Pat. No. 2,640,296 issued on June 2, 1953, to M. A. C. Johnson
et al. is representative, are well known and employ a pair of rings
between which extend radial vanes having either a fixed or in some
cases, an adjustable pitch. The latter type of toys are generally
adapted to be rotated by employing a mechanical device detachably
coupled to the hub of the toy. Such devices will generally lift
vertically and then float downwardly as the spinning velocity
decreases.
Although these various prior art devices display aerodynamic
qualities which are suitable for throwing between individuals or
alternately for use by a single person, the apparatus of the
present invention is adapted to provide the combined aerodynamic
features of both. Thus, the device of the present invention is
adapted to be thrown in a spinning motion between two persons, and,
display lift or drop, not available with prior saucer-type
devices.
SUMMARY OF THE INVENTION
By employing an outer ring concentric with and spaced from an inner
vane supporting ring, the apparatus of the present invention allows
the device to be easily held and manually spun such that it can be
thrown between persons. Apparatus embodying the present invention
comprises a central hub, an intermediate ring concentric with the
hub and supporting a plurality of radial vanes extending between
the hub and the intermediate ring. An outer ring is concentrically
mounted to the intermediate ring by means of a plurality of
radially extending support members.
It is an object of the present invention to provide an improved
flying device adapted to be thrown in a spinning fashion.
An additional object of the present invention is to provide a
flying device having an outer ring to provide an accessible hand
hold.
Still a further object of the present invention is to provide a
flying toy adapted to display lift or drop when thrown in a
spinning fashion.
These and other objects of the present invention will become
apparent upon an examination of the drawings together with the
following description thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to FIGS. 1 through 3 there is shown a flying device
10 embodying the present invention and comprising a circular hub or
inner ring 20. The hub can be formed in the shape of a solid or a
hollow ring 22 as shown in FIG. 2. Extending radially outwardly
from the hub 20 is a plurality of vanes 25 which are positioned
between the hub 20 and a circular concentrically spaced
intermediate support member or ring 30. Each vane includes pin
means 27 extending from opposite ends thereof. The pin means 27 has
one end 28 fitted into a pin receiving aperture 18 of the hub 20
and an opposite end 29 extending into a pin receiving aperture 39
of the intermediate ring 30.
Pins 27 can be molded within the vanes 25 or can be integrally
formed as a part of the vanes with projecting ends 28 and 29
extending outwardly therefrom. The ends 28 and 29 of the pins are
snuggly fitted into apertures 18 and 39 of the hub and intermediate
ring respectively. With this construction the vanes are movable to
adjust the pitch as desired but are relatively rigidly positioned
once adjusted such that they will not move during use.
As seen in FIG. 3, each of the vanes 25 is generally rectangular
shaped with a cross section in the form of an airfoil. The vanes
have a relatively flat bottom surface 23 and a curved upper surface
24 and can be adjusted within members 20 and 30 between a
downwardly depending position shown in solid lines in FIG. 3 to a
horizontal position shown in phantom lines in FIG. 3 or other
desired positions. Alternate vanes can be adjusted to a horizontal
position while the remaining vanes are positioned downwardly to
provide a desired predetermined control effect. Likewise, vanes on
one side of the device 10 can be tilted downwardly while the
remaining vanes on the opposite side are horizontal or tilted
upwardly to impart a turning aerodynamic property to the device
when it is thrown. With this device therefore, it is possible to
experiment with various vane positions to produce the desired
aerodynamic effect.
A circular outer support member or ring 40 is provided as a hand
hold and is attached to the intermediate ring by means of a
plurality of support ribs 35. In use, the device is held by
gripping ring 40 between ribs 35 and throwing the device in a
spinning fashion. It is noted that members 20, 30, 35 and 40 can be
solid or hollow although the hollow members shown provide an
overall reduction in weight of the device and require less
material.
An alternative embodiment of the invention is shown in FIG. 4 in
which the vanes 25 are wedge shaped. As seen in FIG. 5, the vanes
25 of this embodiment also have a cross-sectional shape
corresponding to that of an airfoil. With the wedge shaped
configuration, a greater number of vanes 25 can be positioned
between the hub 20 and the intermediate ring 30 thereby providing a
somewhat smoother operating flying device.
The hollow ring hubs 20 shown in FIGS. 1 and 4 can be replaced with
a solid hub 20 comprising a disc of material 26 as shown in FIGS. 6
and 7. If desired, this disc could be hollowed in its center area
26' as shown in dotted lines in FIG. 7.
The device can be manufactured with or without variable pitch
vanes. If the vanes are fixed for example, the device can be molded
in halves A and B indicated by the dividing center line X in FIG.
2. In such case the vanes and support members or rings can be
hollow as shown, or solid. Also, the pins could be eliminated if
desired by molding the vanes directly to the hub and intermediate
member. The two molded halves are then joined and sealed. Any
suitable material such as polyethylene, P. V. C. or other
thermoplastic molding material can be employed for molding the
halves. Likewise any suitable sealing means such as heat sealing,
cementing or the like can be employed to join the two halves.
When the device is manufactured for variable pitch vanes; the outer
ring, intermediate ring and ribs joining these rings can be molded
in the same manner described above. Likewise, the vanes and pins
can be separately molded as can the hub. The unit is then assembled
by inserting the pin ends into the apertures in the hub and then
into the apertures of the intermediate ring (or vice versa).
It is important that the pins fit snuggly into the apertures to
allow adjustable movement without allowing the vanes to shift in
position during flight of the device. To this end, the pins and
apertures respectively can be polyhedral in cross section as shown
in FIG. 8 at 27 and 39.
With such construction, the somewhat resilient molding material
will allow the vanes to be adjusted incrementally to several
vane-holding positions.
In one embodiment, the rings 20, 30 and 40 had a cross section
diameter of 3/8 inch and a circular diameter of 1 1/4 inches, 6 1/4
inches and 8 inches respectively. The vanes were approximately 2
inches long by 3/4 inch wide. It is apparent that these dimensions
can be varied both in relation to one another and in scale.
These and other modifications to the preferred embodiments shown
will become apparent to those skilled in the art but will fall
within the spirit and scope of the present invention as defined by
the appended claims.
