Definitions

  • the invention relates to a touch potentiometer, in particular for a rapid instruction device on an observation and / or gun vehicle, the touch potentiometer is arranged inside the vehicle around an observer position and has a tubular insulating sleeve in which a resistance track and a contact track arranged coaxially to each other at a certain distance from each other are.
  • the terrain is out constantly visually observed inside the vehicle, either directly from the open hatch or via permanently installed angle mirrors. If a potential target is discovered, it must for precise assessment by a rotatably mounted periscope, its field of view is severely restricted. For this it is necessary to use the periscope (and if necessary the gun barrel) as quickly as possible in the direction of the target, i.e. the The observer must transfer the direction that he has visually captured to the periscope, so that he can quickly find his way through the terrain when the view is clear. Generally It is common to instruct by operating a directional handle or joystick servo-driven turning of the periscope or tower, with the direction inside the Vehicle is displayed on a scale. As a rule, the observer must have his Change posture and change direction on the scale, making it easy to find the direction becomes difficult and valuable time is lost.
  • EP-A-0 455 838 discloses a rapid instruction device which does not have the disadvantages mentioned above.
  • a tactile potentiometer is arranged along a hatch edge in a ring around the observer area, which serves as an analog angle sensor for the rapid drive of a periscope.
  • the touch potentiometer has a flexible, hose-like insulating sleeve which is formed from a semicircular hollow profile.
  • a resistance track Arranged on the semicircular inside of the insulating sleeve is a resistance track, which consists of a resistance wire which is guided to move longitudinally in a tube made of electrically conductive elastomer.
  • a contact track is arranged on the flat inside of the insulating sleeve, which is formed from a flat profile made of metal.
  • Pipe pieces are placed on the ends of the hose in which the resistance wire is guided.
  • the ends of the resistance wire are connected to a cable by means of flexible stranded conductors, the flexible stranded conductors being guided in a helical manner in the tube pieces.
  • the tactile potentiometer is attached to the hatch edge with its flat contact surface, while the semicircular part of the insulating sleeve with the resistance membrane attached to the inside faces the observer's place. If an observer actuates the touch potentiometer in a targeted direction by squeezing the tube-like insulating sleeve at the relevant point until the resistance track touches the contact track, an electrical potential is tapped, which is a measure of the direction in which the periscope must be swiveled .
  • the tactile potentiometer of the above-described quick instruction device has the disadvantage that when bending to adapt to the hatch edge, the tube-like Insulation can buckle and an undesirable contact between the resistance and contact track will be produced.
  • the flat profile used as a contact track made of metal no smaller radii are possible when installing the touch potentiometer, so that depending on the design of the hatch edge, difficulties may arise.
  • the resistance track is mechanically stressed with each actuation, so that changes in resistance may occur and a new adjustment necessary is.
  • Another disadvantage is the relatively complex and expensive connection the resistance wire with the cable.
  • the invention has for its object a touch potentiometer of the type mentioned propose that does not have the disadvantages mentioned above.
  • tubular insulating sleeve consists of two profiles, with at least one of the Profiles a stiffening device is provided.
  • stiffening device consists of tubular integrated in one of the profiles Channels, the stiffening device in one, an actuating surface of the touch potentiometer having profile is integrated.
  • 1 denotes a touch potentiometer, which has a tubular insulating sleeve 2 .
  • the insulating sleeve 2 is composed of two profiles 3, 4 , for example made of silicone rubber, and has an essentially rectangular cross section.
  • a stiffening device is provided on the insulating sleeve 2 , which consists of two tubular channels 5, 6 , which are integrated in the one profile 3 , which has an actuating surface 7 of the touch potentiometer 1 .
  • the channels 5, 6 are arranged on both narrow sides of a rectangular recess 8 , which is provided symmetrically to a central axis 9 on the inside of the profile 3 .
  • a contact track 10 is attached, which is formed from a highly flexible flat wire.
  • a running parallel to the operating surface 7 open side of the profile 3 is sealed by the other profile 4 in the final assembly of the Tastpotentiometers. 1
  • the profile 4 is guided in the profile 3 like a dovetail, with trapezoidal guide strips 11 of the profile 4 engaging in trapezoidal guide grooves 12 of the profile 3 .
  • the resistance track 14 consists of a resistance wire 15, on which contact beads 16, separated from one another by insulating rings 16a , the inner bore of which is larger than the outer diameter of the resistance wire 15 , are made of electrically conductive material, for example made of elastomeric materials.
  • the walls 17, 18 of the channels 5, 6 facing the interior of the profile 3 are curved in the shape of a circular arc, the center of curvature being on the central axis 9 and coinciding with the center of the resistance wire 15 .
  • the outer diameter of the insulating rings 16a is somewhat smaller than that of the abutting contact beads 16.
  • the ends of the insulating cover 2 are sealed with a plug 19, wherein a connecting cable 20 is guided through a plug 19th
  • the connecting cable 20 has three conductors, one of which is connected directly to one end of the resistance wire 15 and the other conductor is connected to the other end of the resistance wire 15 via a return line 21 .
  • the further conductor of the connecting cable 20 is connected to the contact track 10 .
  • the return line 21 is laid in one of two channel-shaped slotted tubes 22, 23 which are provided in the profile 4 on both sides of the groove 13 and are connected to the inside of the profile 4 via slots 24 .
  • the touch potentiometer 1 is attached to a rail 25 consisting of a C-profile, which engages in grooves 26 located laterally on the profile 3 of the touch potentiometer 1 .
  • the rail 25 is held on an angle bracket 27 which is fastened to the edge 29 of a vehicle hatch 30 by means of screws 28 .
  • the tactile potentiometer 1 described above is connected, for example, to a servo control for the rotary drive of a periscope. If an observer located in the vehicle hatch 30 depresses the actuating surface 7 of the touch potentiometer 1 at the relevant point in a targeted direction until the contact track 10 touches the resistance track 14 , an electrical potential is tapped, which is a measure of the direction in which the Periscope must be swiveled.
