  • the present invention relates to a safety contact rail, in particular for moving systems, such as a moving locking device.
  • DE 33 04 400 C3 describes a safety contact rail for power-operated systems, such as roller shutters, rolling grilles etc. with one on the moving part of the Attachment attached rubber hollow profile known, which is designed as a single-chamber profile is.
  • a blade-like rib is provided within the hollow rubber profile, which is made in one piece with the hollow rubber profile and also made of Rubber is made.
  • the surface of the blade-like rib is considered electrical conductive contact surface, being on the inside of the hollow rubber profile the cutting edge-like rib also an electrically conductive Contact surface is provided so that when the safety contact rail is deformed, such as hitting an obstacle in the closing area of a door that is deformed by the hollow rubber profile and with its inside applied conductive contact surface in contact with the conductive contact surface the blade-like rib comes.
  • This allows a circuit to be closed and a signal for controlling the drive device are output so that for example a closing movement of a gate when hitting an obstacle is stopped.
  • a safety contact rail as well propose a locking device which is suitable for a wide range of applications are suitable.
  • a safety contact rail should be put together be proposed with a locking device with which the response be set according to the respective requirements can.
  • the safety contact rail for a moving system such as a moving one Locking device according to the invention has a hollow profile with a deformable area, preferably made of an elastic material, which for Example of a locking device, such as a roller shutter, rolling grille or the like can be attached.
  • the hollow profile can both along the entire closing edge of the locking device. However, it is also possible to provide a hollow profile only at certain points on the closing edge.
  • At the At least one electrically conductive area is provided on the inside of the hollow profile, which, for example, by coating the elastic material with conductive Fabrics such as graphite or the like can be produced. It is also possible conductive elements, such as thin metal nets on the corresponding Lay on surface or connect to it.
  • At least one freely movable contact element is located in the hollow profile, which is preferably formed without a positive connection with the hollow profile.
  • the contact element in its rest position with a surface area on the inside of the hollow profile and preferably has a conductive area on it Surface which, when the hollow profile is deformed by an external force, such as an obstacle that interferes with a closing movement brought with the electrically conductive area on the inside of the hollow profile can be used to close a circuit and thus control signals for example for the drive of the locking device.
  • the deforming the elastic area of the hollow profile leads to a reduction in the size of the interior, whereby the contact element lying in the interior with sufficient Deformation of the hollow profile pressed against a conductive surface of the interior to close an electrical contact, for example.
  • the contact element that is freely movable in the interior of the hollow profile can be used, for example, with a safety contact rail running along the entire closing edge slightly pushed in or removed laterally be, by means of different sized or shaped Contact elements a desired response behavior of the safety contact rail can be achieved.
  • a contact element with a larger diameter already leads to one smaller deformation to contact the respective conductive areas of Contact element and hollow profile, which increases the sensitivity.
  • Contact elements with a relatively small diameter are only after one stronger deformation of the hollow profile against the conductive areas of the interior of the hollow profile so that the response sensitivity is reduced becomes.
  • the entire surface of the contact element is preferably designed to be conductive, so that even with a rotation or displacement of the contact element Always a conductive area in the direction of one within the hollow profile also has conductive area of the hollow profile, so that both conductive areas when deforming the hollow profile can come into contact with an electrical Make contact.
  • the interior of the hollow profile is advantageous when it is installed Provide the upper side with a conductive area, so that through the Gravity on the lower inside of the hollow profile contact element does not come into contact with the conductive area through a lateral movement, but only by a force acting against the closing direction, which leads to a Deformation of the hollow profile in the direction of its top leads.
  • the contact element is preferably approximately round, so that twisting of the contact element has no effect on the response behavior of the safety contact rail Has.
  • other shapes for the contact element can also be used selected, such as a triangular or polygonal cross-section, or a star shape to achieve the desired response. It is also possible to have the contact element along the safety contact rail with different cross sections, for example in the middle area of a roller door to generate a greater sensitivity than in the Marginal areas.
  • the contact element can be designed as a hollow body, for example in shape of a pipe. It is also possible to make the contact element solid without a cavity, for example as a bar element.
  • the diameter of the contact element or the maximum distance two points lying in cross section on the circumference of the contact element advantageous in the range of 0.1 to 0.9 times the minimum inner diameter of the hollow profile.
  • This can increase the sensitivity of the safety contact rail can be varied by a certain size of the contact element the degree of deformation required until a conductive area of the contact element touches a conductive area on the inside of the hollow profile can be.
  • the absolute size of Contact element or hollow profile for the response behavior of the safety contact rail play an important role and preferred in the area of some mm to cm.
  • the hollow profile and / or the contact element is advantageously made of rubber. However, it is not necessary for the entire hollow profile made of elastic material or To manufacture rubber. It is only possible when installed downward, for example, of a region of the hollow profile pointing away from a roller door to be made of elastic material so that it is deformed by an obstacle can be. The remaining part of the hollow profile can be made of plastic, for example or metal. Likewise, the contact element can be made entirely of rubber are manufactured. Alternatively, it is also possible as a contact element, for example a metal rod or tube or other object to be selected with at least one electrically conductive surface area.
  • a weight element can advantageously be used to generate an asymmetrical weight distribution be integrated into the contact element in order to use gravity to define a certain defined rest position of the contact element.
  • a contact element made entirely of rubber can be one in its Have recessed metal rod lying outside, which at a suitably shaped contact element can ensure that due to the Gravity is the area provided with the metal rod below, so that Example of a web protruding from the contact elements in the rest position points above.
  • Both the contact element and the hollow profile are particularly preferred provided a connection for an electrical line so that, for example, to a Control for driving the locking device led an electrical signal can be if the conductive areas of the contact element and the Touch hollow profile and thus a circuit is closed.
  • the hollow profile is preferably airtight, so that it is pressure-sensitive Switch can be connected, causing a deformation of the hollow profile triggers the pressure sensitive switch and appropriate control or Stop signals are output to the drive of the locking device can.
  • An active component is advantageously provided on the safety contact rail, which with at least one conductive area of the hollow profile and at least a conductive area of the contact element is connected, so that by this active electrical component, such as a quartz crystal or similar, affects a voltage applied between these conductive areas can be.
  • this active electrical component such as a quartz crystal or similar
  • Vibrations are modulated onto the applied voltages, so that in the case of contact of the respective conductive areas, this vibration pattern changed - or completely suppressed - so that by such a change in the waveform upon presenting an obstacle can be closed, which led to the deformation of the hollow profile Has.
  • An obstacle can thus be reliably detected, using an suitable control circuit, the drive of the locking device can be stopped can.
  • the safety contact rail can also be used without such active components operate.
  • the invention further relates to a contact element for a safety contact rail, which is made of elastic material and on its outer Surface has at least one conductive area.
  • the invention relates to a locking device with a safety contact rail as described above and a drive for the locking device, which is controlled by a controller, which is in electrical connection with the safety contact rail.
  • FIG. 1 shows a safety contact rail made of rubber with a hollow profile 1, in which a tubular contact element 2 made of rubber is arranged is.
  • the hollow profile 1 can with its top on the closing edge of a gate be attached and has a conductive interior on its upper side Area 1a on, as shown in Figure 1 by hatching.
