Description

10 15 20 447 603 2 felkälla i funktionen av en anordning av ovan beskriven typ. Ändamålet uppnås enligt uppfinningen med ett säkerhetsarrangemang av det slag som definieras av patentkraven. 10 15 20 447 603 2 source of error in the operation of a device of the above described type. The object is achieved according to the invention with a security arrangements of the kind defined by patent claims.

Ett utföringsexempel på uppfinningen i form av en klämskyddslist för maskinellt drivna portar skall beskrivas nu närmare under hänvisning till bifogad ritning. Klämskyddet innefattar en gummilist A som är fylld med en elektriskt ledande fluid. En växel- strömkälla 3 strömförsörjer fluiden via tilledare l och 2. En strömtransformators kärna 4 omsluter listen 1 och dess lindning är inkopplad i drívkretsen 5 för porten. Transformatorn avkänner sålunda huruvida ström flyter genom fluiden i gummilisten A. Om så icke är fallet beror detta antingen på att kraften F hopklämt listen så att strömbanan brutits eller på spännings- bortfall t ex förorsakat av en yttre kortslutning 6. I båda dessa fall bryts portens drivkrets 5.An embodiment of the invention in the form of a terminal block for mechanically operated doors shall is now described in more detail with reference to the appendix drawing. The clamp protection comprises a rubber strip A which is filled with an electrically conductive fluid. A gear power source 3 supplies power to the fluid via conductors 1 and 2. The core 4 of a current transformer encloses the strip 1 and its winding is connected in the drive circuit 5 for the gate. The transformer thus senses whether current flows through the fluid in the rubber strip A. If not In this case, it is either because the force F is squeezed strip so that the current path is broken or on the voltage failure, for example, caused by an external short circuit In both cases, the gate driver circuit 5 is broken.

I ett alternativt utförande kan strömtransforma- torn ersättas med en optokopplare, anordnad i listen och inkopplad i portens drivkrets. ”rf- ~In an alternative embodiment, the current transformer tower is replaced by an optocoupler, arranged in the strip and connected to the gate drive circuit. ”Rf- ~

10 15 20, 447 eos g PATENTKRAV10 15 20, 447 eos g PATENTKRAV 1. Säkerhetsarrangemang vid anordning för indike- ring av tryck eller kraft pà exempelvis tryckknappar, kantskydd på portar, trampmattor eller allmän posi- tionsdetektering, vilken anordning är av den typ som innefattar en eller flera kanaler (A) i ett elastiskt, elektriskt isolerande material och av vilka åtminstone en innehåller en elektriskt ledande fluid, som vid normal drift genomflytes av en elektrisk ström och därigenom bildar en strömbana, vilken ingår i en elekt- risk primärkrets (l, 2, 3) inrättad att aktivera reak- tionsmedel (5) för tryck och kraft och vilken bryts när nämnda fluidinnehàllande kanal vid extern påverkan sammanpressas under fluidens undanträngning, k ä n - n e t e c k n a t därav, att nämnda aktivering är anordnad över en sekundärkrets (4), vilkens drivkälla utgöres av nämnda strömbana, definierad mellan sina ändpunkter, och vilken innehåller nämnda reaktionsmedel (5).Safety arrangement in a device for indicating pressure or force on, for example, pushbuttons, edge protection on gates, pedal mats or general position detection, which device is of the type which comprises one or more channels (A) in an elastic, electrically insulating material and at least one of which contains an electrically conductive fluid, which in normal operation is flowed through by an electric current and thereby forms a current path, which is included in an electrical primary circuit (1, 2, 3) arranged to activate reactants (5) for pressure and force and which is broken when said fluid-containing channel is compressed by external influence during the displacement of the fluid, characterized in that said activation is arranged over a secondary circuit (4), the drive source of which is said current path, defined between its end points, and which contains said reactant (5). 2. Arrangemang enligt kravet l, k ä n n e - t e c k n a t därav, att den elektriska strömmen i fluiden är växelström, att kanalmaterialet är genom- släppligt för magnetiskt fält och att sekundärkretsen innehåller en ledarespole vars kärna omsluter kana- len/kanaler.Arrangement according to claim 1, characterized in that the electric current in the fluid is alternating current, that the channel material is permeable to magnetic fields and that the secondary circuit contains a conductor coil whose core encloses the channel / channels.
