, , , .. . . . . . . .. -2~737~3 With reference to Figures 1 and 2, the projectile, generally indicated at 10 comprises two major componen-ts.
The firs-t beiny a main body or container which in this par-ticular embodiment is in the form of a plastic bottle :L1 having a body portion 12 and an outle-t 13, which is formed to include a radial rim 14 and an externally threaded neck 15. The seconcl component comprises a in assembly 16 which incllldes in this configuration three fins 17 which are spaced equally at 120 degree intervals around a cen-tral hub 18 to ex-tend radially therefrom. ~Iub 18 has a central passageway l9 extending substantially therethrough, that passageway being in-ternally -threade~ such -that i-t can be threadably engaged with the externally threaded portion of neck 15.
Hub 18 as can be seen from Figure 1 is also provided wi-th a radial rim 19~a), which rim when the fin assembly is threadably attached ko the bottle 11 abu-ts rim 13 on -the bottle outlet. If required a rubber gasket (not shown) can be sandwiched between rims 13 and 19 to provide a seal. The only other feature shown in Figures 1 and 2 impor-tant to the operation of -the invention is the provision of an ex-tension 20, which extension is includiny an axial passageway which communica-tes through the hub 18 to the projec-tile. The purpose of this extension ~ill be described in grea-ter detail hereafter.

Figure 2 shows the projeetile comp].etely assembled.
Loolcing now at Figures 3 ancl 4, there is shown the launch mechanism. This mechanism, which is of very simple cons-truction, comprises a pump 21 which is similar in construction to a conventional bicycle pump. The pump comprises a longitudinal cylindrical barrel 22 which houses a piston 23, (shown in dotted outline) which is reciprocated wi-thin the barrel 22 by p:is-ton rod 24 and handle 25. At the end of the pump remo-te from the hanclle, and in -this embodiment fixedly a-ttaehed thereto, is a cylindrical connec-tor 26 which extends at 90 degrees to the pump 21.
As ean more clearly be seen from Figure 5, conneetion 26 has a passageway 27 extending eompletely there-through, communicating directly with the bore of barrel 22 of pump 21. The upper end 28 of connect.or 26 ~see Figure 4) is provicled with a circular recess 29 and the lip 30 surrounding -the reeess has three separate e~tensions or projeetions, spaced apar-t one from -the o-therO Two of these projections indica-ted at 31 are at -the forward end of connec-tor 26, the remaining projection 32 being diametrically opposite projeetions 31.
The remaining component of the pump assembly is a latch 33 which is pivotally attaehed at 34 -to pump 21~ Latch 33 is of the double hook type operation of -the latch being effeeted by a pull cord 35.
~ _ ~737~3 The operation of the toy rocket launcher accordincJ to the invention can be readily apparent rom Figure 5.
The fin assembly encl of proJectile ln is positioned such that extension 20 sea-ts wi-thin recess ~9 oP connector 526. A rubber washer 38 ~Figure 5) is positioned at -the bottom of recess 2~ such that when the latch is operable, ie: locked to the fin assembly, -the waster cushions the end o~ the fin assembly ie: extension 2~, compresses same ancl thus provides resistance agains-t the latch which holds the roeket in sealing relationship wi-th the launeherO Once seated, the lower face 35 o~ central hub 18 presses against the gasket in the bottom of recess 29 effecting a seal, but by virtue of the aforementioned passages, permi-ts fluicl communieation between the pump and the projectile. One way valve means 36 (see Fi~ure 5) are included within connector 26, permitting fluid flow only in one direction, ie: from the pump to the projectile.
To ensure vertical positioning of -the projectile, one of fins 15 is located between ver-tieal projections 31, these projeetions serving to stabilize the projeetile while in position prior to launch.
To hold the projectile in position, latch 33 is pivoted towards the projectile and in-to surfaee en~a~ement with -the projectile such that hooks 37 of latch 33 bear downwardly against the upper surface of radial rim 13 pressuring ,: , . .:
.
2~37~3 against the rubber washer 38 as rnentionecl heretofore.
The projectile is -thus held firmly in the launch mechanism and is in a condition :Eor operation.
Once -the container has been pressurized by actuation of the pump -the la-tch is released by pull cord 35, air pressure is expelled from the projectile -thus providing the thrust to "fire" the projectile from the launch mechanism.
A second embocliment of the subject invention is shown in Figure 6 through 9. For ease of understanding, like numerals have been used for like components.
The structure of the projectile 10 is very similar to that shown in Figures 1 ancl 2, however, as can be seen in Figures 6 and 7, the fin assembly 16 differs from that of the first embodiment by the exclusion of rim 18~a) on hub 18, and a modified extension 20. As will be described hereafter, the modification to e~tension 20 of the fin assembly 16 is to accommodate the launch mechanism of E'igure 8.
The launch mechanism of Figure 8 comprises a pump 2, the operational mechanism of which is identical to that shown in the first embodimen-t. At the end of pump 21 remote from the handle, the cylindrical barrel 22 is slotted transversely at 40. An air passageway 41 extends -through the bottom of slot 40 to communica-te with the interior of the pump. A non-return air valve, not shown, may be located : ' . ' ,,, , , ~, .
~73~
with that passageway. The area around passageway 41 is .recessed to accommodate a rllbber seal 42.
A cylindrical lalch mechanism 43 is provicled wh:ich is sliclably loca-tecl on the outer surface o:E pump barrel 22.
Mechanism 43 comprises a sleeve or slide having a longitudinal ~-shaped slot A4 removed from one end whi~h slo-t extends a short distance aloncJ -the axis of the barrel 22 and a circumferen-tial rim 45 extending radially ou-twardly from the sleeve a-t the end opposite -the slot 44.
The rim 45 provides for the attachment of cord 35, -thus permit-ting the sleeve to be slid along the barrel 22 by pulling of cord 35.
To prevent rota-tion of the sleeve abou-t barrel 22 when being moved longitudinally from one position to the other, a groove is for~ed on -the inner surface of the sleeve, extending the length thereof. This groove locates and cooperates with a longitudinal ex-tension or guide 46 formed on the outer surface of the barrel 22.
The operation of the latch mechanism, according to Figure 8 wi.ll be described with reference to Figure 9, which shows schematically, and in sec-tion, -the mechanism supporting the projectile 10. For clarity only one fin 17 of fin assembly 16 has been shown.
As can be seen, the projectile lQ is positioned - " , ' ~

2~73~3 vertically with extension 20 o~ fin assembly 16 located withi.n slot 40, -the flanged end 201a) o~ extensivn 20 butting the rubber seal 42 in the recessecl area of the slot.
Tlle sleeve as slicler 43 is shown in both tlle "latched" and "unlatched" posi-tion in -this Eigure, the lat-ter posi-tion in dot-ted outline.
Once the projec-tile is in posi-tion, slicler 43 is movecl forwardly into the "la-tchecl" position where the slot 44 is guided so that -the portion of e~tension 20, namely 20(b) en-ters slot 44. This action presses extension 20 downwardly, and flangecl end 20(a) is forcecl into sealing engagemen-t with washer or seal 42. The projectile is thus firmly held in the :launch mode. To release -the projectile after -the main body has been pressurized, it is only necessary to pull on cord 35 which draws the s].ider 43 rearwardly, allowing slot 44 to disengage with projection 20 of fin assembly 16.
While the device in both embocliments can be made to opera-te successfully in the configurations as shown, it is has been found aclvantageous, as can be seen in Figu:res 5 and 9, to provicle a small quantity of water 39, ie: 4 to ounces depending upon -the in-ternal volume of the container, within the pressure chamber of the projectile. This not only acts to stabilize the projectile when in flight, bu-t it also allows -to higher pressures to he generated within -the projectile. The water when initially expelled also provides a thrust co~ponen-t.
.., .:, .. .. . .
' 6 2~737~3 With this mechanis~l, projectiles have been "fired" to heights in excess of sixty feet.
As was mentionecl in the ini-tial portion of this specifica-tion, -this toy is environmentally a-ttrae-tive. As can be seen from the drawings, the projectile bocly is a eonventional plas-tic bottle, commonly sold containing soft drinks ancl mineral water. Xince such bottles can be found in mos-t households, -there is no problem in finding spare components should the projec-tile become damaged in use.
Thus, this inven-tion has provided a secondary use for such bottles prior -to the need to recycle, which process is extremely expensive.
