Definitions

  • the invention relates to a limit switch for gate drives according to the preamble of Claim 1.
  • Such limit switches for gate drives for example of sectional doors or Up-and-over doors are known. They generally include two or more contact elements one of which is moved when the gate closes and opens, while another is usually arranged stationary. The function of the The door drive is based on the fact that the door is in an end position by contact the contact elements an electrical contact between the movable and the fixed contact element is produced, thereby generating a signal or is interrupted that the door drive comes to a standstill.
  • Limit switches for gate drives use contact elements whose Alignment to each other after a long period of operation, for example of undesirable deformations or wear can change such that no electrical contact of the contact elements in an end position of the gate or does not come about reliably. The malfunctions caused by this of the gate can not only lead to considerable material damage, but also Endanger people if, for example, a specified minimum height of one Sectional gates are undershot.
  • the object of the present invention is the generic device such to further develop that always reliable even after a long period of operation Function is guaranteed.
  • This task is based on the generic limit switch solved that at least a first contact element one in the direction of the point of contact with a second contact element, preferably extending in an arc shape Has side and the second contact elements flexible in this direction is executed.
  • This ensures that the preferably arcuate first contact element already before the end position of the gate, the second, touches flexible contact element and this elastic in the end position of the gate bends.
  • the resulting in the direction of the point of contact when the Tore's compressive force causes electrical contact between the two Contact elements come about safely. Because of the device according to the invention this is also the case if deformations occur after prolonged operation or wear and tear on the contact elements that occur with generic Devices can already lead to a malfunction.
  • it is not of a reliable function of the device according to the invention Meaning which of the contact elements when opening and closing the gate movable and which is designed to be stationary.
  • the Contact elements can be arranged on contact holders, one of the contact holders when opening and closing the gate is moved while another contact holder is stationary.
  • the arrangement of the contact elements on contact holders has the advantage that, with a correspondingly detachable design, it is easy Exchange of the contact elements for contact elements of different designs and / or size is possible.
  • the movable contact holder can be arranged on a carriage, which on a drive element of the door drive is attached.
  • a drive element of the door drive is attached.
  • Such sledges will be Usually used to connect the gate to the gate connected linkage and preferably designed as a belt or chain Manufacture door drive.
  • the slide attached to the drive element guides when opening and closing the gate a defined between two end points Movement and is therefore suitable for holding the contact holder on the one of the contact elements is arranged.
  • a second contact element comprises a contact shoe which can be plugged onto a projection, wherein the contact shoe and / or the projection are elastic.
  • the usage a simple contact shoe as a contact element enables a cheap one Construction of the device according to the invention.
  • the contact shoes are on the The projection can be plugged on, which ensures interchangeability. Thereby that the contact shoe and / or the projection are made elastic, at Touching both contact elements one acting in the direction of the point of contact Force exerted on a consistently safe formation of the electrical Enables contact.
  • One or more projections can be provided for receiving the contact elements be arranged on one of the contact holders.
  • one or more of the protrusions are arranged on a transducer which is in one the contact holder is insertable.
  • This provides a high degree of flexibility for the invention Device achieved in that an exchange of the transducer the use of differently spaced first and second contact elements enables without having to replace the entire contact holder would be necessary.
  • This embodiment also allows the transducer with the corresponding connections and not the entire contact holder made of electrical conductive material must be made. It would be conceivable that the transducer with the projections electrically conductive and the contact holder made of plastic are.
  • the first contact element can be made in the direction of the point of contact the second contact element consist of bent wire, which makes it simple and cheap construction is achieved.
  • the fixed contact holder can be mounted at different positions, facing each other in the direction of movement of the movable contact element are spaced. This will achieved that not the contact element itself, but the contact holder on which the contact element is arranged, is displaceable.
  • the fixed contact holder is releasably fixable on a contact rail. Because of the detachable It is possible to attach the contact holder in different positions to arrange, which allows fine adjustment of the end point of the door operator is.
  • the contact rail and the fixed contact holder can be profiled areas have, the profiled area of the contact rail corresponding the negative image of the negative area of the fixed contact holder is executed.
  • the profiled areas can have one or more grooves and / or have projections.
  • the adjustability of the end point of the Door operator depends on the division or subdivision of the profiled areas. For example, shows the profiled area of the contact rail Tooth profile, it is sufficient for a targeted displacement of the contact holder, if it only has a projection that fits into the corresponding tooth profile the contact rail engages.
  • a rough setting of the end point of the door operator can be achieved that the contact rail on a carrier, a projection or on a wall detachably attached by adhesive, preferably adhesive strips is. Following such a relatively imprecise fixation of the contact rail takes place by means of the profiled areas of the contact rail and the contact holder a fine adjustment and thus an exact definition the end point of the door operator.
  • the limit switch 10 shown in Fig. 1 includes one when opening and closing a movable contact holder 20 and a fixed contact holder 30.
  • the movable contact holder 20 is connected to the drive element of the door drive connected sled arranged.
  • the contact holder 20 comprises an arc executed contact element 22, which in corresponding holders of the contact holder 20 is fixed.
  • the contact holder 30 which is stationary when the gate is opened and closed has the Contact elements 32 and 32 '. These are mounted on protrusions 36 and 36 ' as is also clear from Fig. 2.
  • the contact elements 32 and 32 ' exist from contact shoes, whereby a simple and cheap design is achieved.
  • FIG. 3 illustrates that the contact elements 32 and 32 'on the projections 36 and 36 'of a transducer 40 can be plugged on and together in this state can be inserted into the contact holder 30 with the sensor 40.
  • the projections 36 and 36 ' are flexible in the direction perpendicular to the front surface shown in FIG. 3 executed so that the attached contact elements 32 and 32 'in this Direction are movable.
  • the movable contact holder 20 is fixed on the stationary one Contact holder 30 moves, it comes before the limit switch is actuated first to touch the first contact element 22 with a second one Contact element 32. Due to the curvature of the first contact element 22, the second contact element 32 is bent in accordance with the extent of the curvature, that due to the elastic projection 36, the first contact element 22 the second contact element 32 exerts a corresponding force. Once the moveable Contact holder 22 has reached such a position that the first contact element 22 comes into contact with the second contact element 32 ' electrical connection between the second contact elements 32 and 32 ', so that the door drive is interrupted in this position. For example, if the gate is in 1 moves back, take the contact elements 32 and 32 'return to their original position due to their elastic mounting.
  • Fig. 4 shows the contact holder 20 attached to the carriage 60 with the arcuate executed contact element 22.
  • the contact holder 20 is on the underside of the carriage 60 screwed to it.
  • the contact rail 50 which by means of adhesive strips 70th is attached to a carrier.
  • the fact that the contact rail 50 on different places of the carrier can be attached is an individual Design and adaptation of the limit switch to different requirements, such as. Gate height or end position possible.
  • the adhesive strips 70 allow the Contact rail 50 approximately at the desired position on the carrier to assemble.
  • a fine adjustment of the switching point or the end position of the Gate is made by means of the profiled areas 301 and 501, each on the stationary Contact holder 30 and arranged on the contact rail 50 are.
  • the contact rail 50 includes the tooth profile 501, in which a negative image of profile 501 engages corresponding profile 301.
  • the profile 301 is also designed as a tooth profile or as a single projection be engaged in the corresponding profile 501 of the contact rail 50. If a desired position of the contact holder 30 is determined, this is determined by means of areas 301 and 501 are connected to contact rail 50. After intervention of the profiled areas 301 and 501, the position of the Contact holder 30 changed only when necessary and sets reliably in the operating state the end position of the gate.
