Abstract

ABSTRACT
An improved disk shaped implement with protruded rims is employed in throwing games. The continuous peripheral groove and the cave-in formation of the rim provide better gripping for the hand of the user. The rims and other elements of the disk are symmetrically designed so that the disk can be thrown in both the upright and reversed positions.

Description

3L2t~73~

SPE.CIFICATI0~
This in~tention relates a circula-r disks with protruded rims to be thrown through the sir in spor~ing games7 Toys resembling an inverted saucer ha~e been using in throwing games for many years. The toy is gripped by hand and throwing is accc~plished with wrist snapping motion~
Heretofore the existing flying saucers as described in U.S. Pat No. 3,359,67~, 3,72~,122 and prior art are designed with the crown portion of the saucer held upright when the saucer flys. ~lere is a distinct difference in the con~ex and COnca~Je sides of the saucer. The user has to place the saucer in such an uprighk position to be able to lauhch it.
If the position is reversed, said saucer will have a difficulty to fly.
I ha~e found -that this disadvantage and incon~enience may be overcome by making the elements of the saucer s~nmetrical hori~ontally and vertically. The elimination of the raised crown portion of -the existing saucer and the symmetry of the new irnpro~ed configuration will permit the user to throw the improved saucer in b~th the upright and reversed posi-tions.
The presen-t in~ention provides additional improvements in the configuration and profile of a fl~ing saucer of the existing types. The new impro~ed in~ention is referred to as the flying disk which is usually made of plastic or light weight materials~ Said flying disk p~-ovides a double faced configuration comprising a circular central portion having a raised centre with thickness diminishes outwardly to its circumferencial boundar,y which is defined by a first predetermined radius~ The thicker centre pro~ides additional rigidity and stability ~,lhen the disk flys. A symmetrically protruded peripheral portion circumscribes the central LZ~13Lt73 ~L

portion having i-ts inner and outer boundaries defined b~ a second and a third predetermined radii and greater than said first predetermined radius~ In the middle of the peripheral portion there is a continuous groove e,Ytending around the peripher~ of the disk. Joinning integrally with the peripheral portion and the central portion is the connec-ting portion partially filled with superimposed concentric raised ridges.
In drawin~s which illustrates the ernbodiments of this invention~
10, Figure 1 is the top or bot-tom views of the presently preferred embodiment;
Figure 2 is the elevation of the disk shown in Figure l;
Figure 3 is a section of the line A A of Figure l;
Figure 4 is the top or bottom plan views of an alternate embodiment;
Figure 5 is the elevation of Figure 4;
Figure 6 is a section of -the line B B of Figure 4~
The implement illustrated resembles a circular disk 10 as can be observed from Fig, 1. S~mnetry is the distinct difference between this invention and p,rior art versions.
As can be seen from Figo 3~ the elements above ~d belo~ the horizontal axis ~-X and on ~o~ side of the vertical axis Y
are identical. The-top side of -the disk ]0 can become -the bottom side depending on the manner the user places the disk 10 ,Again referring to Fig. 3, at the outer circwmference is the peripheral portion 13 ~ith rims protrude up~ardly a~id downwardly from the ho,rizontal axis X-Y. Located in the midclle of the peri-pheral portion 13 is a groove 15 ciLcumscribing the perimeter of the ~isk 107 ~liS groove 15 forms a d,epression 3 so that the finger of the user c~m be pressed upon~ Said groove lS, together ~1ith the cave-in formation 1~ between the peripheral ~L21~1~73~

po.rtion 13 and the co~mec-ting po.~tion 16 provide a means whereby -the disk 10 is easily gripped by the user before launching~ and since the disk 10 usually f~ys in the direction parallel to is hori~on-tal a~is X-X, said groove 15 also furnishes a guidance for the disk 10 to travel. The central portion 11 , which h~s a physical appearance of a segrnent of a sphere has a thicker raised centre 12 0 Its thickness diminishes outwardly to its circumferencial boundar~
Joinning the peripheral portion 13 and the central po:rtion lL

integeally is -the connecting portion 16. In the present preferred embodiment7 said connectlng portion lS is essentially a flat circular surface partially filled with a plurali-ty o~
concentric superimposed ridges 17 which apart frGm their functlon of increasing stability in the fligh-t, gives a good decorative appearance of the disk 10.
Fig 4, 5, and 6 illust:rate an al-ternate embodiment of the flying disk of the present invention. The peripheral portion 25 and the connecting portion 23 resemble those of Figo 1~ 2~ and 3J with the exception that the eentral 20: portion 2~ is now basically a hole tJi-th a predetermined radius. Between the central portion 2~ and the connecting portion 23 is a continuous slopping ~ircular su:rface 22 circwnscribing the cent:re 210 While the above description contains many specificities, these should not be construed as limitations on the scope O:e the invention~ but rather as an exemplicxtion of one preferred embodiment thereof~ Many other variations are possible.
For example the embodiment as shown in Fig.. 4~ 5, ~Ind 6.
Accordingly~ the scope Oe the present invention should be determined not by the embodiment illustrated, but by the appended claims and their equivale.nts~

Claims

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A circular disk to be used in throwing sporting games comprising:
a central portion having a raised centre with thickness diminishes outwardly to its circumferential boundary defined by a first predetermined radius, said central portion resembling a segment of a sphere;
a peripheral portion having protruded rims, circumscribing the central portion;
a connecting portion extending between the peripheral portion and the central portion and having inner and outer boundaries integrally formed with said central and peripheral protions, the improvement characterized in that, elements on said central portion, peripheral portion and connecting portion are symmetrically placed on both faces of said circular disk providing a means whereby said circular disk can be thrown in the upright and reversed positions;

2. A circular disk as defined in claim 1 wherein a groove located in the middle of the peripheral portion extending circumferencially around said circular disk, whereby said groove provides a means for the user to grasp conveniently and easily;

3. A circular disk as defined in claim 1, wherein a plurality of concentric superimposed ridges are located on the surface of the connecting portion.
