  • the present invention relates to a signal generator, in particular pressure or vacuum signal transmitter for Protection of pinching points for mechanically operated Doors, gates or the like, as well as for switching elements, Safety edges, safety mats or the like.
  • a signal generator in particular pressure or vacuum signal transmitter for Protection of pinching points for mechanically operated Doors, gates or the like, as well as for switching elements, Safety edges, safety mats or the like.
  • Profile element in particular hollow profile element.
  • Such signal generators consist essentially of one Profile element, in particular hollow profile element with a Chamber, which is located in the longitudinal direction in the profile element extends. For example, a is attached to this chamber Pressure sensor connected.
  • the present invention is therefore based on the object based on a signal generator of the type mentioned create, which eliminates the disadvantages mentioned and with which in a very simple and inexpensive way Security in operation permanently with increased security can be checked.
  • At least one Profile element is formed from at least two chambers.
  • These two chambers are preferably continuous in one Profile element, especially in a hollow profile element arranged one above the other and running in the longitudinal direction intended. In the end these can be connected to each other be, but this to the outside towards an environment are closed.
  • these two chambers can each Connect connections, one connection for one Pressure sensor and another connection for a pulse generator is provided.
  • the pulse generator can generate permanent signals in the Send operation through the auto switch and this way check it for leaks and functionality. These test signals are measured in the pressure sensor. The Test signal completely passes through the signal generator.
  • a membrane chamber is then connected to the membrane formed, which is preferably open at the end.
  • side openings in the Membrane chamber to be provided to equalize the pressure guarantee.
  • the membrane can and can be elastic at least partially formed from one of the two chambers his. There is no limit to the invention here.
  • the present inventive concept also includes that Arrange chambers one above the other or even side by side.
  • the profile element is preferably arcuate and provided with a flat base.
  • Hollow sections can have multiple chambers with or without a membrane be arranged.
  • the profile element can be rectangular and elongated very flat to make one To create signal generator, which, for example, also for Safety mats or narrow safety edges is suitable.
  • the individual chambers can be placed side by side or be arranged one above the other. You can also influence take the actuation behavior of the signal generator by for example the cross section of the individual chambers round, is oval or rectangular.
  • an oval chamber is formed, the is arranged perpendicular to the direction of actuation, so results by squeezing the oval trained chamber a cross-sectional enlargement what generates a negative pressure as a switching signal.
  • a corresponding vacuum signal on one Vacuum sensor can be measured or recognized.
  • Corresponding negative pressure and / or positive pressure signals can then assume a pulse generator in operation to check the functionality of the signal generator. This should also with the present inventive concept be included.
  • a signal transmitter R 1 is essentially formed from a profile element 1, which preferably has an elongated hollow profile element inside, two continuous chambers 2.1, 2.2 lying one above the other.
  • the chamber 2.1 is preferably a flow and the chamber 2.2 formed as a return line in the profile element 1.
  • the profile element 1 is preferably of an elastic type and can be formed from a rubber element. With a Base area 3 can be on any object be determined.
  • the chambers 2.1, 2.2 are preferred arranged one above the other in the profile element 1. These run continuously in the longitudinal direction of the profile element 1. Die Chambers 2.1, 2.2 are airtight when viewed individually formed from the profile element 1.
  • the profile element 1 can manufactured in any length or on a any desired length can be cut to length.
  • a further signal transmitter R 2 is shown, in which, in the manner described above, the profile element 1 has two chambers 2.1, 2.2, which are preferably arranged one above the other.
  • the difference is that the chamber 2.2 through a membrane 4 is divided and forms a membrane chamber 5, which is open at each end.
  • a signal transmitter R 3 is shown, which likewise consists of a profile element 1, in which a chamber 2.1 is provided opposite the base area 3, which corresponds approximately to an outer, arch-like contour 6 of the profile element.
  • Membrane 4 connects to chamber 2.1 and divides profile element 1 into a further chamber 2.2 and / or membrane chamber 5.
  • the membrane chamber 5 can be opened at the front or to be introverted. This will be discussed in more detail later.
  • FIG. 3 shows a signal transmitter R 4 , in which the chambers 2.1, 2.2 according to FIG. 1 are arranged, a further membrane chamber 5 adjoining the chamber 2.2, which is preferably open at the end.
  • a signal transmitter R 5 is shown, the profile element 1 of which is preferably of rectangular cross section and very flat.
  • the chambers 2.1, 2.2 above a membrane 4 are arranged side by side, with below the Membrane the membrane chamber 5 is formed. This too can front, preferably open. It has proven favorable, a plurality of such Arrange profile elements 1 side by side to form a surface to create.
  • Corresponding signal generators can for example as components of a switch mat or the like. serve.
  • FIG. 5 shows a similar signal transmitter R 6 according to FIG. 4, with the difference that the individual chambers 2.1, 2.2 are arranged one above the other.
  • the membrane 4 and a membrane chamber 5 are connected to the chamber 2.2.
  • the signal transmitters R 1 to R 6 described above are assigned connections 7.1, 7.2 on the end face or as desired along the profile element 1.
  • Connections 7.1, 7.2 on one end or both ends to provide.
  • Connection 7.1 preferably engages, as is the case, for example is shown in Figure 6c, in a chamber 2.1, wherein a further connection 7.2 opens into a chamber 2.2.
  • the connections 7.1 to 7.2 are inserted at one end into the chamber 2.1, 2.2 in the manner described above, the other end of the chambers 2.1, 2.2 being sealed airtight to an environment and by means of a bridging 8 are connected.
  • a profile element according to the invention has in one preferred embodiment two chambers, which are preferably arranged one above the other.
  • the chambers are throughout in the profile element as through openings educated.
  • the two connections 7.1, 7.2 serve, on the one hand a pressure sensor and on the other hand a pulse generator to connect.
  • the pressure sensor receives a corresponding signal when Squeeze or mechanically operate the Profile element 1, for example when opening or closing a door, a gate or the like. Simultaneously can into the second chamber 2.1 through the connector
  • the pulse generator emits permanent impulses on the Profile element 1 there. This allows the complete Signal generator, in particular the complete profile element 1 be checked for leaks with both chambers 2.1, 2.2.
  • the two chambers 2.1, 2.2 preferably face pressure fluctuations, in particular a pressure increase caused by a Temperature increase, compensated by the membrane 4 become when the subsequent membrane chamber 5 for Environment, preferably open at the front.
