Abstract

Abstract The invention described herein envisages a personal propulsion-device which may be fitted to the back of an individual, adjusted thus, and removed there-from, by way of an appropriate support; the purpose of such a device being that of imparting thrust direct to the aforesaid individual's person.

Description

3~32~

A Personal propulsion-device The individual utilising the i~vention will him/her-self procure suitable non-motorised means of dis-placement~ either by sliding - skates, skis or skids -or by rolling.

Thus, the object of the invention described h.erein is that of providing a propulsion-device which may be fitted direct ~o and re~oved from the individual, embodied in such a way as to preclude any danger or risk to the latter during utilisation thereof.

A further object of the invention is that manoeuvre of such a device should be rendered easy, and that removal thereof from the individual's person - should the need arise - be simply and speedily accomplished.

Not least of the objects aimed at by the invention is that of arranging all parts of the propulsion-device necessary to manoeuvre thereof, to fitting-up and removal thereof from the individual's person, and to function thereof, in a compact fashion - associated thus with an appropriate support which may be fit~ed to the individual's ~ack.

Such advantages are arrived at-by the inventlon desc-ribed herein, ~hich i characterised in that it com-prises:
- a motor serving to rotate the screw-propellor attached.thereto for:the purpose of propulsion;

~v~

- an anatomically-contoured support capable of adjustment and of being fitted to and removed from the individual'fi ~ack; said motor and ~rope~~
l.~r atta.ched to ~he rear of said support, which is equipped further with a fuel tank and silencer --supplying fuel to and damping exhaust from said motor, respectively - and parts necessary to the manoeuvre, acceleration, ignition and shut-off of same, all positioned within easy reach of the individual;

- an annular element, or hoop, inside of w.hich said screw-propeller is free to turn, and which i5 immovably fixed to said support by way of a conjoining surface-area within which said motor is housed.

A further characteri.sti.c distinguishing the invention is that the support takes the form of a single ~.lock, the forward part of which.~eing i~e$ted ~ith.shape.
such as matches the anatomi.cal contour of the.indi~idua~s back, and divided ïnto three distinct sealed c~m~er one of which serving as the motor fuel-tank; a ~econd - into ~hich exhaust gases flow pr~or to th~ir final emission through a ~ail-pïpe - serving ~s s~lencer, the third being positioned ~etween the former two, and serving thus as a non-functional parti.tioning-chamber, or void.

Further features and advantages. of .the invention desc-rlbed hereln will emerge ~ore clearly from the d~tailed description following, ~.llustrated ~y way of example with the aid of a sheet of drawings in which:.

~Z~382~
, 3 - fig 1 shows a view of the invention in perspective from the side-and-front;
~- fig 2 shows a view of the invention in perspective from the slde-and-rear.

Referring now to the above drawings, the device as descri~ed herein comprises a motor 1 - internal com-bustion type in this instance - and a screw-propeller 2 attached to the shaft thereof.

Motor-and-propeller are fixed immovahly to a support 3 .
provided with special means for its ~e.ing fitted to and removed from the back of the individual utilising the device. More precisely, support 3 consists of a s}n~le body, or block, whose forward-facing side 3a is moulded anatomically after the fashion of a back-rest, with a slight curve uppermost permitting adapt-ation of the support 3 as a whole to the individual's back.

The ~Iock itself is divided ïnto three cham~ers 3,..~0 and 11, the first and topmost of which performing. the function of a tank for the supply of fuel to motor.1, and duly provided with a filler cap ~a; the second chamber being positioned at the ~ottom of said support 3 and designed to receive post-com~us,tion exhaust gase~
from motor 1 by way of an appropriate port.~8 prior to bringing about their emission through tail-pipe 6 - thus acting as silencer, and, if need ~e, cleaner;
the third cham~er lying hetween the Eormer t~o, and serving to create a void for separation thereof.

In order t~ ensure co~plete elimin~tion.of the ris.ks ~L2~

and dangers attrihuta~le to propeller 2 ~hen re~olving at speed, the latter iE circumscribed by an annular element, or hoop 7 fixed immovably to support 3 by way of a conjoining surface area 8 whichinthe embodi-ment set forth takes the form of a cage 8a.

The individual making use of the invention -thanks to this arrangement- enjoys the maximum of protection, the motor 1 itself being located internally of cage 8a.

The entire assembly compri~ing hoop 7 and cage 8a, besides incorporating features of compactness and of safety, must be embodied structurally so as to offer the least resistance imaginable to airflow, as well as being correct aerodynamically so as not to jeopard-ise the propulsion-device's efficiency.

Part~ for control of the motor -more preci.sely, those pxoviding for accelerati.on thereof ~ consi.~t s:imply of a protective sheath 12 (clearly di~cerna~le in t~e drawings) inside which one has a ca~le 13 connecting with the motor throttle 14. The cab.le itsel~ ~ay ~e pulled taut or slackened off ~y ~eans- of a pull-ring 15, for instance, as located at the free end of ca~le 13 in the drawing (fig 2).

The self-same ~heath.~ay al~o house .th~se. controls for brinying about the motor's ~ i~nition and shut-off.
More preciseIy, the appropriate ~iring ~ay be located in sheath 12 which connect~ the motor coil --or at any rate, the motor's electrical starter-circuit- ~ith a button 16 duly located at pull-ring 15.

lZ03~32~

It will be clear enough,that the controls thu~ desc-ribed might e~uall~ well ~e em~odied in some other fashion, provided that ease of access thereto on the part of the individual remains 11ni ,~red, Provision might be made further for additional safety devices such as, for example, a mercury switch 17, which would be sensitive to the propulsion-device's angle of inclination away from the vertical. Said switch 17 would in fact shut off the motor automatic-ally once the device as a whole leans further fromthe vertical than angle A illustrated, ~hic~ constit-utes the predetermined ~m~

In case the necessit~ should ari~e, the indiYidual ha5 ample facility of un~linging the entire devi.ce as swiftly as is humanly possi~le; thi~ ~ ~irtue of a pair of upturned-U.shoulder-braces 20 which perform the dual-function of carrying the device, and of permitting its speedy removal from the individual's shoulders. The same principle obtains in the ca~e of pull-ring 15, which incorporates an automatic qL~k-release operated by urther button 23.

In ~.nQ, in order to proYi.de t~e. individual ~ith ,a, safe and sure means of.h~ldïng the deYice ~ïrm and stable once slung at the ~ame time respectïng the obvious need for ~aximum'pos~ihle accident-prevention the bottom of support 3 is fitted ~ith a waist-~elt 2 incorporating the quick-release catch denoted 22.

A description of the devicels, function would see~ to lZ038Z~.

be superfluous, seeing that hoth the principle in-volved and utilization proper are a~undantly simple.
In any event, use o~ the device provides its user with a forward or backward thrust, by dint of the screw-propeller's 2 being caused to turn t which will be of greater or lesser force depending upon the speed at which the latter is made to rotate.

The device thus illustrated in the drawin~s and desc-ribed herein would find ïts most advantageous ~pplic-ation in ski-ing, since the ski-er tAus equipped would possess freedom of~movement, togetAer with the poss-i~ility of controlling the device in the fashion most suita~le to him/her.

Lastly, it will be evident that the propulsion-compon-ent proper utilized in the de~ice might be embodïed differently to that descri~ed herein, w1thout by any means straying from the basic innovatory concept behind the propulsion device as claimed ~elow.
