9 Claims. (01. 4681) This invention relates generally to launchable missiles and launching means for such missiles, and is particularly applicable to toys, such as model airplanes, and launching devices for the latter.

One of the objects of the present invention is the provision of a launchable missile in combination with launching means for such missile, and wherein said launching means comprises a rotary member journaled in a fixed handle, the latter having means for arresting the movement of the rotary member at will, and with which rotary member is secured a rotatable missileengaging element so arranged as to release the missile when the movement of the rotary member is momentarily stopped.

Another object of this invention is to provide a missile in the shape of a toy, such as a model airplane, provided with an engageable element, and a launching device including a handle and a rotary member journaled in the handle, and with which rotary member is associated, by means of two flexible connectors, a substantially hook-shaped, rotatable missile-engaging element adapted for engagement with the engageable element of the missile, and wherein the handle is provided with hand-operable means for stopping the rotation of said rotary member whereby the two connectors between the rotary member and the hook-shaped element are caused to change their position so that the hook-shaped element is rotated to release the missile and launch it.

Still another object of this invention resides in the provision of a launcher for missiles of the type indicated, and which missile launcher is ,equipped with stop means for arresting the movement of the rotary part of the launcher at will, and wherein position indicating means for said stop means are provided whereby the desired type of launching a missile is determined.

The foregoing and still further objects and important advantages of the present invention will become more fully apparent from the following description in connection with the accompanying drawings, forming illustrative parts of the present invention, but intended to serve merely for descriptive purposes without confining this invention to the specific showing, and

wherein:

Fig. 1 is a perspective illustration of the device in accordance with the present invention;

Fig. 2 is a sectiontaken on line 2-2 of the upper part of Fig. 1; l

Fig. 3 is a partial sectional viewthrough the rotary member of the device, takenon line 3--3 Fig. 4 is a vertical section through the hookshaped element of the device;

Fig. 5 is a partial section made through the missile along line 5-5 of the lower part of Fig. 1;

Fig. 6 is a section taken on line 6-4; through Fig. 5;

Fig. 7 is a diagrammatical illustration, partly in section along line 'l-l of Fig. 1, of the device, with its rotary parts shown in full lines prepara tory to the point of launching the missile, and with the rotary parts being. shown in broken lines at the point the missile is being released, the device being viewed in the directionof the section line arrows 11;

Fig. 8 is a diagram of the device shown at a point of launching the missile in another manner than that indicated in Fig. '7, and the view taken being in the direction of the arrows of section line 1-1 of Fig. 1; and r Fig. 9 illustrates a modified construction of the launcher, partly in cross section.

Referring now specifically to the figures, numeral I0 denotes a hollowhandle provided with a disc-like flange ,at the periphery of which latter are indicated difierently colored areas, such as red, green and blue, enumerated, respectively, at l2, l3 and I4. In a suitable enlargement I5 of disc ll there is mounted a spring-loaded plunger 16, the purpose of which will be explained presently.

Operatively associated with handle 10 is a rotary member l1 composed of a shaft [B jour- Y plunger I6 is in its full line position, wedgeshaped extension 22 will clear it (see Fig. 3); obviously arm 20 must always clear plunger I6. Secured to arms 20 and 2 l, by means of flexible connectors 23 and 24, is a missile-engaging element 25 comprising a substantially hook-shaped, ring formation having an outer peripheral channel or groove in which flexible connectors 23 and 24 are movably guided, as clearly seen in Fig. 4. The ends of these connectors are secured to the respective ends 26 and 21 of element 25.

A missile intended to be launched by the above described device is preferably in the form of a flying toy, such as a model airplane 28, and is provided with a recess 29. Transversing the recess is an engageable element in the shape of 3 a pin 30, adapted to be engaged by missile-engaging element in the manner shown in Fig. l, recess 29 serving to not only accommodate the element 2-5 but to permit it to rotate, and to guide it while being rotated to a missile-releasing position.

Modification Fig. 9v discloses a different construction of the missile launcher, although its function in respect to the missile remains unaltered. The handle 3| of the launcher is split longitudinally, its two halves being united along plane .32 when all its parts are assembled.

A journal 33 for a relatively short shaft 34 is centrally located in the handle and is provided with a suitable end recess for accommodating an annular shaft enlargement 35. ment limits the longitudinal movement of the shaft in its. journal.

Attached to the shaft end projecting from the handle is. a double bar 36 provided with end perforationsf or accommodating the ends of flexible connectors 23 and 24 extending to missileengaging element 25, as in Fig. 4.

Arran ed about midway between the outer shaft end and enlargement there extends from the shaft a pin 37; which is free to, revolve in a suitable recess. Movably mounted in the upper half of the handle is. a plunger 38, normally urged in outward direction by a spring 39:, and having an interior enlargement for limiting its outward movement. An extension of the plunger is intended to engage pin 31 when it is desired to arrest the rotation of the shaft.

At the periphery of the handle there are provided markings in different colors, such as red, green and blue numbered, respectively, at l2, l3 and I4. These markings facilitatethe positioning of the handle at three different angles to the normal, whereby three different types of the launching of the missile-are effected, as has been explained in-connection with Fig. 1.

Operation When it is. desired to launch the missile, the 'latt elr'is suspended from the launcher'by 'means'of hook-shaped element "25, in the manner illustrated in Fig. 1. swiinguntilrotfary member 11 commences to reivolve 'within the. handle in such a 'way that the irontfiace of f wedge-shaped extension 22,mo ves in the direction toward stop plunger [6. Such direction would be counter-clockwise when observing Fig. 1 ,and clockwisejwhen observing Figs. '7, and 8.

When the missilehas attained the desired velocity, plunger '16 isft'hrust into the pathof wedgeshaped'extension zz, in the manner indicated in Fig. 7;. As. a result, rotor 11 is stopped, while missile 28, s till engaged by hook-shaped element 25, continues inits'travel. Due to the now fixed position ofthe'rotor, connectors 23 and 24' change their position, andg'due totheir positional change, commeuc'eto revolve missile-engaging element 25 in plane passing through the peripheral groove thereof, During this positional change of the connectors, connector 23v so-to-speak unwinds itself'from element '25, whereas a portion of'connector 24 is wound up on that element, in the manner indicated in'br'oken lines in Fig. '7. This revolving. movement of element 25' causes the latter to release pin. 30 of missile 28, thereby launching, the missile.

hsis'tatedin.connection with the description of Fig. l. handle flange H is equipped with red,

That enlargegreen and blue markings at its periphery. When it is desired, for instance, to so launch the model airplane that it attains a high altitude, handle I 0 is held with the red marking of flange l l topmost, while the airplane is suspended from the hook in the manner shown in Fig. 1. When now stop plunger 16 is thrust into the path of wedge extension 22 airplane 2-8: is. released while it travels upwards, as indicated in broken lines in Fig. 7.

When it is desired to launch the model airplane for a great distance flight, instead of for attaining a high altitude, the launching must take place a moment earlier than is required for a high altitude launching. In other words, stop plunger l6 is thrust into the path of wedge ex- The launcher handle is then tension 22 when blue field I4- of flange l I is uppermost. Great distance launching is indicated in Fig. 8. When a medium flight is desired ranging between high altitude and long distance, the handle must be held with green field E3 of flange II in the uppermost position.

In all events handle H3 is held parallel to the ground and the plane is released when hook 25 is below'the handle.

From the above described launching operations it becomes clear that the'opcrator of the device is completely relieved from the necessity of exercising particular skill to determine the point of release for any desired flight of the missile, the only requirement being that the operator holds the handle with the color designating the desired flight in uppermost position.

It is to be understood that the launching operations described in conjunction with the embodiment disclosed in Fig. 1 apply equally to the launcher modification illustrated in Fig. 9.

While in the foregoing specific structures of the present device are described, it is quite obvious that changes and improvements may become necessary in adaptingthe device for launching different types of missiles, such changes and improvementslying within the broad scope of the present invention as defined in the annexed claims:
