Definitions

  • the present invention relates to a device for in ⁇ dicating a pressure or force, with possible fields of application such as push-buttons, door edge sensors, pressure sensitive doormats or position detecting equip- ment in general.
  • the device according to the invention comprises one or more channels in an elastic material, e.g.
  • one or more of said channels containing a sound-conducting compressible medium, such as air, as well as a sound transmitter at one end and a sound receiver at the other end.
  • a sound-conducting compressible medium such as air
  • sound are here meant frequencies lower than the ultrasonic frequency.
  • the channel or channels are adapted to be included or integrated in rubber strips or the like, for example in door sealing strips of an elastic material, also in existing, conventional door sealing strips.
  • the strip can be mounted in curves since the channel conducts acoustic energy. This makes it possible to use a low power input, which causes a break of the channel to be indicated as an obstacle. If the channel is compressed anywhere along its length by an obstacle, the sound path through the medium is inter ⁇ rupted. The same occurs with any type of fault in the device proper, e.g.
  • the device thus is self-regulating in that the operating means is rendered inoperative on power failure. Moreover, the switching principle may well be used in explosive surroundings since no spark is formed when the switch is closed.
  • the device will be described in more detail below, reference being had to the accompanying drawing and a preferred embodiment, the drawing showing a part of a garage door or industrial gate 1 whose lower edge is provided with a rubber strip 2 having a channel 3.
  • the channel is air-filled, and contains a sound trans ⁇ mitter 4, such as an oscillator ( ⁇ 20 kHz), and a receiver 5 of the sound from the sound transmitter.
  • the transmitter and the receiver may be of conventional type and are each arranged at one end of the channel and provided with lead-ins in an electric circuit comprising a current source S and a gate operating means M.
  • a further channel 6 (de ⁇ formation channel) may extend which is intended to be deformed upon braking of the gate so as not to damage the obstacle which caused the deformation of the channel 3. It is shown at 7 that a force F is applied, and it appears that the channel 3 is deformed before the channel 6, as indicated above.
  • the channel 3 When the channel 3 is deformed, the sound path between the sound transmitter and the sound receiver is interrupted and, consequently, the current to the operating means of the gate 1 is inter ⁇ rupted, whereupon the deformation channel 6 can be de ⁇ formed upon braking of the gate.

Abstract

Dispositif indiquant une pression ou une force appliquée, par exemple, à des boutons-poussoirs, à des capteurs de bord de porte, à des paillassons sensibles à la pression ou, en général, un équipement détecteur de position. Le dispositif comprend un ou plusieurs canaux (3, 6) en un matériau élastique. Un canal ou plusieurs canaux (3) contiennent une combinaison d'émission/réception sonores (4, 5) avec des traversées électriques, la combinaison établissant, pendant le fonctionnement normal, une communication sonore entre l'émetteur sonore et le récepteur sonore. Lors de l'application d'une force externe sur le matériau élastique du canal, le canal est comprimé de sorte que la communication sonore est interrompue.
