Abstract
Abstract A model aircraft glider includes a wing and a fuselage having a resilient nose bumper for absorbing the impact of a collision. The glider has a finger-receiving recess centrally located on an underside thereof near the bumper to facilitate launching of the glider by an operator. The glider further includes a centrally located projection which is cooperable with the finger-receiving recess for hand launching and is cooperable with a resilient member for catapult launching.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
115 words
A model aircraft glider comprising a delta wing and a fuselage, the fuselage being centrally positioned on an upper surface of the wing and the fuselage and the wing being substantially of the same dimension longitudinally, the glider having a finger-receiving recess centrally located on its underside near the forward end of the fuselage, an impact-absorbing bumper attached to the forward end of the fuselage, the bumper having a substantially flat frontal portion, and having sides which extend beyond the forward end of the fuselage and the wing, the sides providing grasping surfaces, said surfaces and said recess being positioned sufficiently closely to each other to provide means for gripping the glider for hand launching.
Claim 2
Dependent Claim
115 words
A model aircraft glider comprising a delta wing and a fuselage, the fuselage being centrally positioned on an upper surface of the wing and the fuselage and the wing being substantially of the same dimension longitudinally, the glider having a finger-receiving recess centrally located on its underside near the forward end of the fuselage, an impact-absorbing bumper attached to the forward end of the fuselage, the bumper having a substantially flat frontal portion, and having sides which extend beyond the forward end of the fuselage and the wing, the sides providing grasping surfaces, said surfaces and said recess being positioned sufficiently closely to each other to provide means for gripping the glider for hand launching.
Claim 3
Dependent Claim
18 words
The glider of claim 1, wherein the fuselage and wing are molded from plastic as a unitary structure.
Claim 4
Dependent Claim
27 words
The glider of claim 1, wherein the bumper is formed of a resilient cellular material having a resiliency greater than that of the fuselage and the wing.
Claim 5
Dependent Claim
109 words
A model aircraft glider comprising a delta wing and a fuselage, the fuselage being centrally positioned on an upper surface of the wing and the fuselage and the wing being substantially of the same dimension longitudinally, the glider having a finger-receiving recess centrally located on its underside near its nose to facilitate launching of the glider by an operator, and having a depending projection centrally located on its underside adjacent to its nose, the projection being spaced from the recess toward the nose of the glider and said projection and said recess being positioned sufficiently closely to each other to provide means for gripping the glider for hand launching.
Claim 6
Dependent Claim
109 words
A model aircraft glider comprising a delta wing and a fuselage, the fuselage being centrally positioned on an upper surface of the wing and the fuselage and the wing being substantially of the same dimension longitudinally, the glider having a finger-receiving recess centrally located on its underside near its nose to facilitate launching of the glider by an operator, and having a depending projection centrally located on its underside adjacent to its nose, the projection being spaced from the recess toward the nose of the glider and said projection and said recess being positioned sufficiently closely to each other to provide means for gripping the glider for hand launching.
Claim 7
Dependent Claim
23 words
The glider of claim 4, wherein the projection is adapted for engagement with resilient launching means for catapulting the glider into the air.
Claim 8
Dependent Claim
19 words
The glider of claim 4, wherein the projection is adapted to serve as a landing skid for the glider.
Claim 9
Dependent Claim
25 words
The glider of claim 4, wherein the projection is formed integrally on a rigid base which is attached to the glider flush with its underside.
Claim 10
Dependent Claim
26 words
The glider of claim 7, wherein the base includes a second projection embedded into the glider for strengthening the attachment between the base and the glider.
Claim 11
Dependent Claim
95 words
A model aircraft glider comprising a fuselage and a wing formed as a unitary structure of rather rigid molded plastic foam, a resilient cellular bumper attached to the forward end of the fuselage for absorbing the force of an impact on the glider, the resiliency of the bumper being substantially greater than the resiliency of the foam, and a finger-receiving recess centrally located on the underside of the glider rearwardly of the bumper, the recess and the bumper being positioned sufficiently closely to each other to provide means for gripping the glider for hand launching.
Claim 12
Dependent Claim
95 words
A model aircraft glider comprising a fuselage and a wing formed as a unitary structure of rather rigid molded plastic foam, a resilient cellular bumper attached to the forward end of the fuselage for absorbing the force of an impact on the glider, the resiliency of the bumper being substantially greater than the resiliency of the foam, and a finger-receiving recess centrally located on the underside of the glider rearwardly of the bumper, the recess and the bumper being positioned sufficiently closely to each other to provide means for gripping the glider for hand launching.
Claim 13
Dependent Claim
43 words
The glider of claim 9, wherein the forward end of the fuselage is flat, and wherein the bumper has a flat frontal portion substantially coextensive with said forward end and the shape of the bumper generally conforms to the shape of the fuselage.
Claim 14
Dependent Claim
52 words
The glider of claim 9, further comprising a projection positioned on the underside of the glider adjacent to the bumper and to the recess, the projection being cooperable with resilient launching means for catapulting the glider into the air and being cooperable with the recess to facilitate hand launching of the glider.
Claim 15
Dependent Claim
19 words
The glider of claim 11, wherein the projection is adapted to serve as a landing skid for the glider.
Claim 16
Dependent Claim
14 words
The glider of claim 9, wherein the glider is a full delta wing design.
Claim 17
Dependent Claim
12 words
The glider of claim 9, wherein the glider is a low-wing design.
