Description
Description The present invention relates to the application of an acoustic warning device and, eventually. also of a radio transmitter to a ski stick.
As it is well known, an ever-increasing number of people practise the winter sports.
In particular, skiing has become a mass sport.
The thronging of the ski slopes with skiers having different ages and skills causes fre-duent and dangerous accidents.
Further dangerous situations are caused by the practise of skiing off the tracks because it frequently involves the forming of avalanches which bury and sweep the skiiers away. Therefore. it should be considerably useful and advantageous to the skier fe>re-warning of its approach the other skiers going down the same slope in order to avoid dangerous collisions. Moreover, the possibility of attracting attention and of signal-ling his own position to the helpers is still more useful when the skier is not able to move in consequence of the wounds and/or the fractures caused by an accidental fal-I S ling off the track as well as in the case the skier has been carried and buried by an ava-lanche.
r1s is known. there are many types of electroacoustical and radioelectrical apparatuses and devices which are respectively suited to emit acoustic signals or radio signals.
In particular, the well known and most widely used radio signal transmitting devices ?0 are those usually contained in suitable housings which can be easily worn by the skier by means of a girdle or other fastening means.
It results that the skier can be easily and quickly localized by the radiolocalizer of the search-and-rescue operators in the case he has been buried by an avalanche or has had an other kind of serious accidents.
25 As it is well known. the actual technology allows not only to reduce the sizes of said localizating electro-acoustical or radio-electrical devices but also to increase their sig-nal power to such a value that the signals can be received at middle and also at long di stance.
'Therefore, the aim of the present invention is to obtain the above-mentioned aims and S advantages. According to the present invention, the above-mentioned aims and advan-tabs are all attained by mounting the following components in the inside of the tubu-lar element forming the pole of a ski stick that is provided with the respective ski stick handle : at least one electronic group for producing acoustic signals and/or one electronic group for producing radio signals as well as devices for emitting respective signals, electric power feeding elements and respective driving elements all suitably mounted and disposed in the ski stick handle.
In order to better understand the features and the advantages attainable by the object of the present invention, this object is hereinafter described , by way of a not limita-tive example only, and with reference to the accompanying drawings , wherein the Fig. t is a cutaway view of the upper ski stick end provided with the respective handle and housing an acoustic warning device. a radio-transmitter as well as the recpective electric power feeding devices , the driving devices and the devices for the emission oi~the respective signals;
the Fig. 2 is a schematic block diagram showing the position of the essential units ?U whether in the acoustic. warning device or in the radio-trasmitter.
Vl-'ith reference to Fig. l, it is to be noticed that in the inside of the tubular element I 1, forming the pole of an ordinary ski stick l, and in correspondence of its end where-upon is applied the respective ski stick handle ? , are inserted the following compo-vents : one electronic circuit GA of a respective acoustic warning device AA

In order to better understand the features and the advantages attainable by the object of the present invention, this object is hereinafter described , by way of a not limita-tive example only, and with reference to the accompanying drawings , wherein the Fig. t is a cutaway view of the upper ski stick end provided with the respective handle and housing an acoustic warning device. a radio-transmitter as well as the recpective electric power feeding devices , the driving devices and the devices for the emission oi~the respective signals;
the Fig. 2 is a schematic block diagram showing the position of the essential units ?U whether in the acoustic. warning device or in the radio-trasmitter.
Vl-'ith reference to Fig. l, it is to be noticed that in the inside of the tubular element I 1, forming the pole of an ordinary ski stick l, and in correspondence of its end where-upon is applied the respective ski stick handle ? , are inserted the following compo-vents : one electronic circuit GA of a respective acoustic warning device AA
and one
2 S electronic circuit GR of a radio- transmitter RS.
In the ski stick handle 2 are also mounted the push-button P and the power switch I, which are driving the respective electronic circuits GA and GR, the acoustic emitter F.A and is realized the housing of an electric battery B for feeding either the acoustic warning device AA or the radio-transmitter RS.
The push-button P, the switch I , the acoustic emitter EA and the electric battery B are all of well known type and are disposed in the body of the handle 2 in such a position as to operate as best as possible.
More precisely, the push-button P is preferably disposed in the upper part of said han-dle ?, as for example it is shown in the above mentioned Fig. 1. in the superior-1 () posterior part of the handle 2. However, the push-button P can be disposed also in other position that be suitable to allow an easy actuation by the user who will be able, while grasping the handle ?, to press the button by means of a anger-tip as preferably the thumb-tip. On the contrary, the switch I is disposed in a position where it is hand-reachable by the skier only of his own will. The acoustic emitter FA is positioned in such a way as not to be covered by the hand which is grasping the handle 2 as well as to allow a rational orientability of its sound signal.
On the contrary, the battery B is housed in a suitable enclosure made out of the handle body 2 and placed in such a way as not to interfere with the grasping of the handle.
As is well known, both electronic groups CJA and GR can be made on the surface of 2U an insulating base by forming conductive tracks that include the necessary' compo-nents as resistors, capacitors, various inductances and integrators.
As it is also well known, each electronic group GA and GR is then encapsulated by immersion into a respective melted block of resin which imparts an high impact strength to the respective group.
?s Obviously, the block of resin enclosing the electronic I,~roup GA and GR
has a cilindri-cal shape with an outside diameter which is equal to the inside diameter of the corre-sponding part of the tubular element 11 of the ski stick 1 in which the block of resin will be inserted and removably fixed in a known manner and by known means.
As it can be seen from the recalled Fig. 1. the electronic circuits GA and GR
are s shown with an ordinary disposition of the respective components ( integrators, resis-torn, capacitors, inductances , etc. j which are all applied on the respective insulating bases whereon, as already said, are made the conductive tracks.
Moreover, the conductors interconnecting to each other such electronic circuits , the batten B, the push-button f, the switch I and the acoustic emitter EA are marked off , 1 ~ for the sake of clearness, with heavy continuous lines.
(t is obvious that on a ski stick 1 can be mounted only one signalling group which comprises. as it is shown, either one acoustic warning device AA or one radio-transmitter RS or. according to the requirements, only one of them.
For example, if the skier wants only to acoustically signalize its presence to the other 15 skiers it will he enough to mount only the acoustic warning device AA which will be used as a "klaxon".
A more prudent skier will choose the complete set including also the radio transmitter RS.
With reference to the block diagram shown in the Fig. 2 there are to be noticed the ?U two signalizing groups and more precisely the acoustic w ~arning device AA
and the ra-dio transmitter RS both electrically feeded by the battery Q.
The part "acoustic warning device AA" includes the push-button P, the electronic cir-cult CAA and the acoustic emitter FA. 1'he part "radio transmitter RS "
includes the switch I, the electronic circuit GR and the antenna A.
Referrin;_,~ to either the block diagram in Fig. 2 or the cutaway view in Fig.
l, it will be hereinafter described the operation and the practical use of the particular application forming the object of the present invention.
Whenever the skier presses the push-button P, the battery 13 energizes the electronic circuit GA . 'the electronic circuit GA produces an alternating current for feeding the s acoustic emitter EA. The acoustic emitter EA generates an audible si~.mal that can be heard also at long distance.
'hhe emitted acoustic signal can have only one frequency or a sequence of frequencies which are successively emitted according to a suitable chronological order.
The monofrequeney or the sequence of frequencies are studied in such a way as to ob-twin the best of signalling performances.
Clearly, the audible signal goes on as long as the push-button I' is pressed.
When the skier actuates the switch I , the battery ~3 energizes continuously the elec-tronic circuit GR. The circuit GR produces a suitable radio-frequency current for feeding the antenna A. The antenna A emits a corresponding radio-signal.
It is obvious that the frequency of the radio-signal RS will be of a type as that nor-many used in the specific field.
Seen as a whole, the circuit can be advantageously completed by the connection repre-rented by broken lines in the Fig. ? . Such connection couples the output of the switch 1 also to the electronic circuit GA of the acoustic warning device AA.
2U In this case, the actuation of the switch I causes not only the emission of a radio-signal but also of~an acoustic simal.
This possible and alternative embodiment results very advantageous because it makes possible to guide the helpers not only with a radio-signal but also with an acoustic sib nal which assists them in the localization of the hurt skier.
Zs A suitable pulse generator T can be connected between the switch I and the electronic circuit GA in order to reduce the energry consumption of the battery B, Said pulse generator energizes or deenergizes the electronic circuit GA
according to suitable time intervals. The result is that the produced acoustic signal is intermittent in such a suitable way as to improve the search and localization possibilities.
s It is to be pointed out that the antenna A ( not shown in the Fig. 1 ) of the radio trans-muting device RS can be constituted by the metallic tubular element 1 1 fonning the pole of the ski stick l . In the case oi~ a tubular element 11 constituted by a non-metallic and non-conductive material, the antenna A can be constituted by a suitable element disposed in the body of the stick handle 2 or in other adequate position.
From what stated and described it is clear that the ski stick with an acoustic warning device and%'or a radio transmitter according to the invention improves the use and the security conditions.
It is to be pointed out that the type . the form and the position of the acoustic warning device AA components and%or the radio transmitter components may be varied.
1 y Moreover, the circuital parts of such devices (AA-RS) may be further miniaturized by means of components which are offered by the actual technolo~rt~.
It is well understood that modifications and variations may be made to the object of the present invention without departing however from the scope defined by the fol-lowing claims with reference to the accompanying drawings and thence from the pro-?() tection e~ctent of the present industrial invention
In the ski stick handle 2 are also mounted the push-button P and the power switch I, which are driving the respective electronic circuits GA and GR, the acoustic emitter F.A and is realized the housing of an electric battery B for feeding either the acoustic warning device AA or the radio-transmitter RS.

On the contrary, the switch I is disposed in a position where it is hand-reachable by the skier only of his own will. The acoustic emitter FA is positioned in such a way as not to be covered by the hand which is grasping the handle 2 as well as to allow a rational orientability of its sound signal.
On the contrary, the battery B is housed in a suitable enclosure made out of the handle body 2 and placed in such a way as not to interfere with the grasping of the handle.
