Abstract

A b s t r a c t a remote radio-control device for a motor drive system of a gate wing with a mobile push-button operated transmitter and a re-ceiver arranged on the gate or drive system which, when a button is pressed on the transmitter, causes the drive system to move the gate wing in one or other direction or take it to an interme-diate stopped position and which is arranged to ensure the trig-gered direction of travel of the gate wing, even without any knowledge of the movement previously made, in such a way that the transmitter has two separately operable push-buttons, one of which gives a signal to close the gate wing and the other a signal to open it, where, in a preferred embodiment, the simultaneous actuation of both buttons generates a signal to stop the gate wing.

tran~mlttar to the opsnlng po6ition becau~a of an ob~;tacle whlch 1~ under ~he gat~ wing, this Is not possible wlth a control device af the aforementioned type wlth only a transrnltter-side pueh-but~on. Thls Involves the dangsr that the ob~eclt l~ d~maged.
Wlthln thls eonvsntlonal Id~ there exlæt further au~ma~i motlon control pr~, for ~xample, responslve ~ 1:he alarm signal of an edge saf~ty ledge af~er a rnains interruptlon or similar disturb-anc~ Thls does, however, r~t Include the abov~d~scrlbed situa-10 tlon of a yate wlng travel control out o~ a certain p~ltlon of thegate wlng ~Ithout the per~ operatlng the transmltter knowlng 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 th~ recelver wlth It8 non-dlsplay~d m~nory con~n~s wa8 ~ d~

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 . ; . - . :.- :-., . ~- . , -1 2 ~

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~

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~ -r~lver whlch For this case of transfer is In an "adoptive or learnln~ SWItChIn9 POsltlOn"~ I.Q memorlzes ~he code re~lved frcm 35 the lransmltter.
