Abstract

Abstract A toy which is adapted to be used as a projectile to be catapulted vertically into the air. This toy is provided with a body that is elongated and shaped so that when it reaches the peak of its climb it assumes a horizontal position and starts to rotate around its long axis. This rotation continues during descent and slows the speed of descent making it possible to catch the toy by hand.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 226 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination comprising an elongated body member having at least the front and rear longitudinal end portions thereof, respectively, in the shape of relatively wide blades fixedly attached to said body member so that said blades cannot rotate with respect to said body member, said blades comprisiNg means for causing said twisting motion in response to movement of said toy through the air, said latter means including the orientation of said blades so that their main surfaces are substantially at right angles to each other, means positioned at said front end portion of said body member detachably engaging the resilient band of a catapult, said other end portion of said body member being adapted to be gripped to stretch said resilient band for projecting the toy aloft when said other end is released, said elongated body member and said blades being substantially balanced with respect to the center of said elongated body so that the toy goes into a horizontal orientation when it reaches its maximum height which horizontal orientation it maintains during its descent, said relatively wide blades being shaped and oriented to cause said toy to rotate around the long axis of said body member and slowing the speed of descent.
Claim 2
Dependent Claim 226 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination comprising an elongated body member having at least the front and rear longitudinal end portions thereof, respectively, in the shape of relatively wide blades fixedly attached to said body member so that said blades cannot rotate with respect to said body member, said blades comprisiNg means for causing said twisting motion in response to movement of said toy through the air, said latter means including the orientation of said blades so that their main surfaces are substantially at right angles to each other, means positioned at said front end portion of said body member detachably engaging the resilient band of a catapult, said other end portion of said body member being adapted to be gripped to stretch said resilient band for projecting the toy aloft when said other end is released, said elongated body member and said blades being substantially balanced with respect to the center of said elongated body so that the toy goes into a horizontal orientation when it reaches its maximum height which horizontal orientation it maintains during its descent, said relatively wide blades being shaped and oriented to cause said toy to rotate around the long axis of said body member and slowing the speed of descent.
Claim 3
Dependent Claim 68 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further characterized in that said blades each comprise a pair of sheet members and said elongated body member includes a rod, each of said pair of sheet members being attached to said rod with said rod therebetween.
Claim 4
Dependent Claim 71 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 3, further characterized in that the portions of said rear blade on the opposite sides of said rod are displaced with respect to each other such that the main surfaces of these portions are curved or angled in the opposite directions.
Claim 5
Dependent Claim 81 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further characterized in that said body member includes a tubular member and said blades each include a pin, the pin of the front blade being attached in one end of said tubular member and the pin of the rear blade being attached in the other end of said tubular member.
Claim 6
Dependent Claim 47 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 4, further characterized in that said front and rear blades are formed of paper plastic or wood.
Claim 7
Dependent Claim 44 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 5, further characterized in that said rear blade is made with a twisted configuration.
Claim 8
Dependent Claim 59 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 5, further characterized in that said rear blade is provided with ribs on opposite sides thereof, said ribs being oriented such that they add air friction to said blade.
Claim 9
Dependent Claim 47 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 5, further characterized in that said rear blade is provided with flaring ribs on opposite sides thereof.
Claim 10
Dependent Claim 56 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further characterized in that the cross sections of said blades taken parallel to the body member are of air foil shape, formed of foam plastic.
Claim 11
Dependent Claim 45 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further charActerized in that said elongated body member comprises a thin rectangular body member.
Claim 12
Dependent Claim 46 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 10, further characterized in that said thin rectangular body member is weighted at each end thereof.
Claim 13
Dependent Claim 45 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further characterized in that the rear blades of said body member are flaired outwardly.
Claim 14
Dependent Claim 54 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further characterized in that opposite sides of both front and rear blades of said body member are twisted, with respect to each other.
Claim 15
Dependent Claim 89 words
In a toy adapted to execute twisting motion when projected aloft, said twisting motion increasing during descent thereby reducing the speed of descent, the combination as set forth in claim 1, further characterized in that said catapult comprises a rod having a tubular cross section at one end with an opening through the side wall thereof, a portion of said resilient band being inserted into said tubular end, said portion of said band being looped over and around said one end of said rod adjacent said side wall opening.
