Abstract
Abstract A toy glider having an improved form of wing construction is disclosed. The glider is made from initially flat sheet stock which is expanded polystyrene. In one embodiment the body and wing are integral while in another the body and wing are separate. In each case the semispans of the wing are provided with score lines and V-notches and when in operative form, the edges of the V-notches are held together so as to give washout twist to the semispans. A shape-holding, rigidifying and balanceproviding metal strip is employed, being positioned between folded-over strips along the leading edges of the semispans and the body, and the overlying portions thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
201 words
A toy glider comprising, in combination: an elongate body portion; a horizontal stabilizer attached to the rearward end of said body portion; and a wing structure at the forward end of said body portion, said wing structure comprising like semispans, each having a substantially straight leading edge extending perpendicular to the axis of the body portion and each formed of initially flat sheet stock, each semispan also including a strip folded under at the leading edge and defining a wing lower surface portion, each semispan having a score line extending diagonally backward commencing from adjacent its leading edge in the root region thereof and extending to a point spaced inwardly of the semispan tip and forwardly of the trailing edge thereof, each semispan having a second score line extending from adjacent the leading edge of said tip to said point and there being a Vshaped notch having its apex at said point and presenting opposite, divergent sides extending therefrom to the trailing edge of the semispan; and means for positioning and holding said divergent sides of each notch in close proximity to each other so as to crease said semispans along their score lines and establish washout twist for each semispan.
Claim 2
Dependent Claim
201 words
A toy glider comprising, in combination: an elongate body portion; a horizontal stabilizer attached to the rearward end of said body portion; and a wing structure at the forward end of said body portion, said wing structure comprising like semispans, each having a substantially straight leading edge extending perpendicular to the axis of the body portion and each formed of initially flat sheet stock, each semispan also including a strip folded under at the leading edge and defining a wing lower surface portion, each semispan having a score line extending diagonally backward commencing from adjacent its leading edge in the root region thereof and extending to a point spaced inwardly of the semispan tip and forwardly of the trailing edge thereof, each semispan having a second score line extending from adjacent the leading edge of said tip to said point and there being a Vshaped notch having its apex at said point and presenting opposite, divergent sides extending therefrom to the trailing edge of the semispan; and means for positioning and holding said divergent sides of each notch in close proximity to each other so as to crease said semispans along their score lines and establish washout twist for each semispan.
Claim 3
Dependent Claim
29 words
A toy glider as defined in claim 1 wherein each semispan merges integrally with said body portion, said body portion being V-shaped and initially formed of flat sheet stock.
Claim 4
Dependent Claim
43 words
A toy glider as defined in claim 2 including a strip of metal disposed between the upper and lower surfaces of said wing and shaped to hold said body Portion in V-shape and said semispans in selected angular relation to said body portion.
Claim 5
Dependent Claim
59 words
A toy glider as defined in claim 3 wherein said body portion is provided with a transverse slit adjacent the forward end thereof to provide a strip joining those strips folded under at the leading edges of said semispans, said strip of metal having a V-shaped portion disposed between said body strip and the overlying portion of the body.
Claim 6
Dependent Claim
69 words
The toy glider as defined in claim 1 wherein each semispan is provided with an additional pair of score lines intersecting at a point on the line of fold of its strip adjacent the semispan tip and diverging therefrom to said tip, and means for positioning and holding the upper surface areas defined between said additional pair of score lines and said line of fold in tucked-in, face-to-face juxtaposition.
Claim 7
Dependent Claim
24 words
A toy glider as defined in claim 1 wherein said wing structure is formed by integral semispans and said body portion is separated therefrom.
Claim 8
Dependent Claim
50 words
A toy glider as defined in claim 6 wherein said semispans are provided with pairs of notches at their leading and trailing edges, said body portion including a center section of V-shape and having facing notches receiving the leading and trailing edges of said wing structure adjacent the notches therein.
Claim 9
Dependent Claim
26 words
A toy glider as defined in claim 7 including a V-shaped strip reinforcing and shaping said wing structure within the fold at the leading edge thereof.
Claim 10
Dependent Claim
69 words
The toy glider as defined in claim 6 wherein each semispan is provided with an additional pair of score lines intersecting at a point on the line of fold of its strip adjacent the semispan tip and diverging therefrom to said tip, and means for positioning and holding the upper surface areas defined between said additional pair of score lines and said line of fold in tucked-in, face-to-face juxtaposition.
Claim 11
Dependent Claim
28 words
A toy glider as defined in claim 6 including a V-shaped strip of material reinforcing and shaping said wing structure within the fold at the leading edge thereof.
