10 Claims. 1
The present application is a continuation-inpart of application Serial No. 220,997, filed April 14, 1951, now abandoned.
The present invention relates to kites and more particularly to a glider carrying kite and means for releasing said glider when the kite is in flight.
According to the invention there is provided a comparatively large kite, which will hereinafter be termed a carrier kite," attached to a conventional kite string and having a glider mounted atop thereof under the tension of an elastic band and normally held in tensed position by means ot a trigger. There is also provided a small kite or release kite which is adapted to climb the kite string to eventually contact the trigger in order to release and launch the glider from the carrier kite. The glider, being launched from a relatively considerable height, will travel a substantial distance before landing.
Accordingly, the general object of the present invention is the provision of adevice of the character described which is of simple construction and inexpensive to manufacture and yet effective and efficient in use.
An important object of the present invention is the provision of means for releasing the glider from the carrier kite while the latter is in flight.
Another important object of the present invention is the provision of novel glider releasing means which are simple in construction and efficient in operation.
Still another important object of the present invention is the provision of glider releasing means which require but a slight force to perate.
Yet another important object of the present invention is the provision of a device of the character described in which the glider is so shaped and so held on the carrier kite that it will easily clear said kite during the initial portion of its launching.
The foregoing and other important objects of the present invention will become more apparent during the following disclosure and by referring to the drawings in which:
Figure 1 is a perspective view of the kite, glider and release kite according to the invention;
Figure 2 is a fractional perspective view of the assembly showing the release kite about to assembly, looking underneath the carrier kite;
Figure 5 is a sectional elevation of the assembly showing the release kite about to contact the trigger for releasing the glider;
Figure 6 is a similar sectional elevation showing the trigger in releasing position; and
Figure 7 is a perspective view of a modified release kite in the form of a disk.
Referring now more particularly to the drawings in which like reference characters indicate like elements throughout, the carrier kite, generally indicated at A, comprises an upper longitudinally extending frame member I and a lower cross frame member 2 attached together at their junction by means of a string loop 3. The frame members support the light weight sheet material 4 attached along its edges to the endless string 4 passing over the ends of the frame members I and 2.
The sheet material 4 is provided with a trigger aperture 5, the edges of which are reinforced by means of an additional layer 6 of sheet material. The longitudinal frame member i has a dependent stop block I passing through the trigger aperture 5 and provided at its lower end with a transverse groove 8.
For better stability, the cross member 2 abuts against the front face 9 of said stop block 1 as shown more particularly in Figures 5 and 6.
A short string H is attached to the loop 3 at its upper end and to a ring [2 at its lower end, said ring being attached to the kite string l3.
The ring l2 serves to abut the release kite l4 while the latter ascends the kite string l3. Said release kite l4 comprises a lozenge shaped sheet l5 of substantially rigid fabric curved upwardly so as to present a substantially convex bottom to the Windward side. This sheet i5 is maintained in a curved state by means of a transverse strut member it made of light wood or the like, contacting the upper face of said sheet l5, and by means of an elastic band it contacting the under face of the sheet 15 and passing through side apertures It made therein to be attached to the recessed ends 20 of the member It by means of rings it. The kite string l3 passes and is guided through a short tube 2! secured to the sheet I 5 on the centre longitudinal axis thereof and forwardly of the centre of gravity of said release kite l4. Thus, when the release kite is loosened along the kite string [3, it will climb thereon in a slightly inclined position, The convex shape of said release kite will render the same very stable in ascent and will obviate the use of a tail.
The glider, generally indicated at 25, is preff function to the tube 2| of the kite l l.
erably made of light wood and comprises an elongated fuselage 26, the nose or forward end of which is weighted by means of a metal element 2?, the tapering rear portion 24 of which is provided with a tail assembly 28 having inclined tail wings 29 as shown in Figure or 6. The lower edge of the middle portion of the fuselage 26 is provided with a recess 30 having a dovetail cross-section forming inclined front and rear shoulders 31 and 32 respectively. The front shoulder ill engages an elastic band 23, the forward end of which passes around the front grooved end 33 of the longitudinal frame i. The band 23 is prevented from jumping oil from said recessed end 33 by a collar 34 enclosing the front portion of the band 23 and the frame member I.
The back shoulder 32 of the recess 3% is engaged by the bent back upper transverse portion 35 or" the trigger generally indicated at 35 and which consists of a light weight metal plate provided with a central rectangular aperture 38 for receiving the longitudinal frame member I and the stop block 1. r
The lower edge of said apertur 38 is bent back to form an arcuate lug 39 engaging the arcuate recess 8 made at the lower end'of the stop block i. The trigger 35 has a downwardly extending tapering arm 40 disposed at right angles to the carrier kite A when said trigger is in armed poi sition as shown in Figure 5. The upper end of the trigger 3% is provided with upwardly project ing ears ii engaging the sides of the fuselage 25 in order to prevent sideways displacement of the glider '25 when in armed position.
'It will be understood that, as the release kite i i ascends the kite string 13, it assumes a slightly inclined position due to the off-center placement of the guide tube, as shown in Figure 5; when it contacts the ring 12, its tail end will kick, up enough to strike the trigger arm to of.
the trigger 35, causing disengagement of the arcuate lug as from the groove 8 and pivotal movement of said trigger. The normally rearwardly inclined top cross portion 35 of said trigger 3% will then take a forwardly inclined position, as shown in Figure 6, at the same time as the whole trigger moves forwardly to disengage'the shoulder 32 of the fuselage 2F; and release the glider 25 which is thus shot forwardly into space by means of the elastic band 23.
' Due to the fact that the nose of the glider 25 is weighted, as shown at 2?, and that the tail wings 29 are tilted downwardly, the glider, upon launching, will not be affected by the wind to tangle with the elastic and will easily clear the forward part of the kite because its rear portion 24 is tapered.
The glider wings 82 are disposed directly over the trigger aperture 5 and the flow of air upward through said aperture provides lift for the glider and thereby minimizes its weight on the kite A when the same is in flight.
While a preferred embodiment according to the invention has been illustrated and described, it is understood that various modifications may be resorted to without departing from the spirit and scope of the appended claims.
