The InYen~ion rel~es to a re~te radi~contr~l devlce ~or a mG~r
drlve sy~tem of a gate wlng or simllar ob~ect having the featurls~
aF the gener3c natlon of cl~im t.
Known oentrol devlces o~ the abov~mantloned type work in such
a manner that, by vlrtue of tha capabillty aF the receiver lto rn~
morlze the previous dlrectlon c~f travel aF the gate wlng, the
tran8mltt0r 18 provlded merely wlth one push-but~n whlch act-
uatlon, accordlngly, can determln0 the gate wlng travel dlrectlon
only In connection wlth the receiver. This appears to be easy ~rom
the aspect ~f handllng and ~iso 3xpadlent for normal use~. How-
ever, there are situa~ions where thls operatlon m~da, whlch flr~
appeared t~ be p~ltlva, turns out ta be di~advantageou~ For
ex~mpl~, always when such a g~te wlng ~ and there l~ ~D d~
mo~tly with large and heavy Indu~strlal gate wln~s ~ Is moved and
kept In a ~7 l~pen posltlon between ~he openlng and clo~lng

af the aforementioned type wlth only a transrnltter-side pueh-

the gate wing movement prevlously made. The triggerlng a1 a
gate wlng movement In such a sltu~tlon can cause also psych~3~
gicai problems.
Accordingly, It le an obJect al the Inventk)n to provlde a gate
wlng control devlce allowlng that the dlrectlon o~ the gate wlng
movement respectlvely trlggered can be dlrectly d~terrnllled by
the operator out o~ any oper~tlonal sltuatlon. Accordlng to a par-
20 tlcularly pre~erred embodlment there Is provlded an smergency-
sb~p functlon whlch Is safe agaln~t errors also In a state af panic~
Startlng from a cc>ntrol devlce of the type msntioned above, hav-
lng the ~e~tures af the generlc natlon oF clalm 1, this obJe~:t l$
2~ eolved by the sharacterlzing ~eatureæ thereo~.

Accordlng t~ the pre~ent Inventlon the transmltter is provlded
wlth two ~epar~tely operable push-buttonæ, one tr1ggerlng a slgnal
1Or the tr~vel o~ the ~ate wlng to the closlng poeltion and the
30 o~her one trlgserlng a slgnal 1Or the travel of the gate wlng to
the openlng posltlon. Accordlngly, It h~ppened Int~ntionally that ~:
the transmltter operatlon wlth only one pu$h-bu~on as mentloned
at th0 be~lnnlng was dropp~d whlch had as a cor)s$quence that

There are sltuations ~ danger where the movement af the gate
wing Just carrled out must be Interrupteci and/or inv3rsed, ~or
example, ht sudden appearance of a psreon or a vehlcle In the
zone of the gate wlng movement stlll to be carrlod out in the
5 respec~lvs dlrect30n o~ travel. In such a ca~e onel oould produce a
~p signai 10r the movement o~ ~he gate wlng by repeatedly
preesing ~he push-button ~ssigned ~ the dlrectlon of travel Just
carrled out. Also by pre~in~ the other push-button provided for
the opposlte diractlon of travel of the gate wing tha latter could
10 be oontrolled to ~he opposite dlrectlon which would~ i~wever, re-
quire the p:ovishn af an Intermedia~e ~top. On the other harc,
movlng the ga~e wlng In the opposite dlrectlon Is not indlcated
when another potentlal obstacle rroves In the path of the opposlte
dlrectlon of travel which can be the ca~ wlth horlzontally moved
15 gates or blg slngl~wlng overhead-gate3 whlch carry out a plvot-
Ing mc~tlon wlth thelr lower edge. In a partlculArly preferred em-
bodlment aF the Invention, and especlally taklng a certaln panlc
re~ctlon Into account, provlslons are made that the operator oF the
transmltter needs not dlstlngulsh the two pueh-buttons but th~t
20 the ~:tuatlon of one af the two push-buttons and especlally alss~
the slmultaneous actuatlon of both push-bu~ns leads ~o an emar-
gency stop for whlch purpose the push-buttons can be arranged
ln close Juxtaposltlon whlch aleo reduces ~he overall slze ~f the
tran~nitter. i !
In a further preferred embodlmerlt care ls taken that repeated
pre~lng o~ the push-buttons ls slmultaneously taken up by the
recelver, whlch for thls purp~e was memorlzlng the prevlous dl-
rectlon of travel ~ the ~ate wlng, and processed ln tern~ a~ a
30 matlonal slgnal In the opposlte dlrectlon. It ls also posslble b~
Judga the slmultaneous actuatlon oF both push-button~ ln 6uch a
manner that the gate wlng ls driven In a dlrectlon opposlte to the ::
prevlous dlrecitlon of travel. These tue functlons for em~rgency
c~s whlch re~ulre that the one who operat~ tha transmitter
36 reallz~ them by a movemen~ vlslble to hln. On ths ather hand,
the two iseparate dlrectlonal push-buttons aF the tran~nltt6r allow
a specil11c movement aF the gate wlng In the one or other dlrectlon

selectad by the operator, wltl?out the recalver memor1zing the dl-
rectlon o~ the previaJs mov~ent made or wlthout the opera~r
knowlng the cQn~nts of the memory. Acoordlngly, ~he operat~r
can sp~:lflcally control the gate wlng In the dlr~ion away ~rom
5 the sltu~ dar7ger when he recognl7e~ a 5itu~10n of darger
already exis~lng but ~oes n~t know the dlrection in which the
prevlous movt~nent o~ the gate wing was mads. This Is very Im-
portar~t not only ~rom the psychoio~lcal vlewpolnt An ex~r~ple: The
operator of the tran~TIltter reailzes a situatlon whereln a vehlcle
10 ha~ moved under a hal~pen ovsrhead gate ~o that any mQvemQnt
aF the ~ate wlng In ttle clo~ln~ dlr~tlon would damage the vehlcle
or Its load ets:. Slnce wlth the known davlce tha ga~e wing could
have been taken bo thls haif open posltion both from the cloelng
posltlon and the openlng posltlon, one must be prepared that with
15 the known constructlon af the transmltter wlth only one push-
button the gate wlng flrst moves towards tha obstacle, wherea~
wlth the construction accordlng to the Inventlon wlth two push-
buttons, one ~or ea~;h of the two dlrectlons c~F travel o~ the gate
wlng, such "faulty movement" can be rellably prevented. On ma-
20 klng these conslderatlons one must take int~ a~count thAt thedoors In questlon here are by no means llght-weight garage door~
but any klnd of heavy Indu~trlal doors or ga~es whteh are e~ulp-
ped wlth powerful drlvlng aggregates ~nd can have hlgh Inertl~
forcsæ.
To prevent that the gate wlng Is operated by unauthorlzed per-
~ons the recelver and the assoclatad transmltter or transrnltters
are provlded wlth a correspondlng cod9 S0 that there can be In-
put an adJu~tably coded Identlfylng slgnal securlng the corres-
30 ~)ondence betwaan transmltter and recelver. Such an identlfylngslgnal l$ made ~v~llable In the 10nn af a parallel slgn~l Input In a
series of m~ry cells, ~or ~xample ten, and i~s then by mean~ of
par~llel~erl~s~onversiorl convertsd to a ~rlal puls0 sJgnal ~nd
r~dl~tran~mltt~d ~ the rec~iver which in turn ~eeds thl~ $erlal
35 sl~nal Inbo ~ reglster or slrnllar ma~ns and comparss It ~r Its
correspondenc~ wlth the parallel Identlfyin~ slgnal there mesr~
rlz0ri. Only after a po81tlvQ re~ult af thls oomparl~ Ignals from

tha transmitter are accepted and interpret~d In the recelver,
whlch slgnals serve ~or the ac~ual oper~lon or mo~/~nent of the
gate wlng. For the pre~ent need of dlffer0nt Ideritlfylng signal~
ten bo thlrt~n memory cell~, whlch can be dually eoded, are
5 enough. Thls slgna~ Is followed by the slgnal lFor ~he Inten~lonal
openlng ~f the gate wlng or by the one for 1:he clo~lng of the
gate wlng. Wlth such a c~de stlil further slgnals ~n be triggered,
for example, ~or ~wltching a tim~llmlted outd~r llght or Indoor
llght, an optlcal alarm devlcs and the 13ke.
I~ there 18 trlg~Gred an ~nergoncy stop signal by a slmultaneous
actuatlon of the mechanlcaily non-lnterlocked pu~h-button~, lthls
can be recognlzed by the operator through the slml~ltan~ous o~
currence of the "open" and Hcle6ed" signals. eut ba~lcaily there
15 can be produced al~o In the transmitter a saparate slgnal lFor the
swltchlng s~ate caused by the slmultaneous operatlon of the push- i
buttons and ~upplled to the recelver. For the so called state of
panlc one can even conslder to p~pone the prevlous outp~t ~f
the Identl~ylng slgnai between transmltter and recelver, whlch
20 means that prlorlty of tlme Is glven to thls stop ~unctlon from
e~ch transmltter by thls speclfic emergency slgnnl. ;
' ,:
Mor~over, the two push-buttons for openlng and closing the gate
wing wlll be utlllzed at the same tlme for trlggerlng and transmlt-
25 tlng the Identlfylng slgnai, rneaning that the switchlng functionsnecessary for the converslerl o~ the parallel slgnai to a serlai slg-
nal and the modulatlon thereof to a carrler etc. ara carrled out at
the same tlme.
30 A code ~or the Identlflcatlon between transmltter and recelver can
be eætabllshed aieo In such a way that the deslred identlfloatlon
code Is r~morlzed In the tranæmlttsr and then tran~ferred to th~ -

purpose the push-buttons can be mechanlcally or eleGtrically
locked or protecte~ against a slmultaneous slgnai output i~ any
5 ather Interpretation af such sirnultaneolls actuation ~f ~th push-
buttons is not provlded. However, problems can arlse In the ~tate
of panlc a~ the latest when the gate wlng Is about to hi~ agalnst
an obstacie for which reason with the present pr~erred embs~
rnent o~ the invention any slrnultaneous actuatlon ~ bath pueh-

stop or ~nergency-$~p signal, particularly so that In a stat~ af
panlc the actuatlon o~ ona or, as mentloned, both push-butts~ns at
the same tlm~ always leads to an Immedlate stop of the moved g~te
wlng. Acoordlng to a further embodlment the sub~equent slmul-
15 taneous actuatlon of bath push--buttons may be Interprated to-
ward~ a dlrectlon o1 travel of the gate wlng opposlte to the pr~
VIOU8 dlrectlon ~ travel, provlded that the recelver Is capable to
m~norlze the dlrsctlon of travel of the gate wlng previousty mada,
whlch Is known per se. The posslbllity of slmultaneous actuation
20 of both push-but~ons 4 and 5 Is wlth the pr3sent embodlment as-
si~ted rK~t only by the lacklng lock agalnst such a slmultaneous
~tuatlon but also by the fact that the push-buttons are arranged
In close Juxtapoeltlon wlthout any caslng web therebetween.
25 Both the transmltter and recelver clrcuit arrangements accordlng
to Flgures 2 and 3 are each equlpped wlth an Integrated clrcult
