Definitions

  • Bowden wires or flexible-cable controls have been used for many purposes and, for example, in the automotive field, are commonly employed to open and close vents, release and lock latching mechanisms and to set and release locking, parking or emergency brakes. Outside of the automotive-vehicle field, they have been used to transmit motion to remote locations and to move a member out of engagement with an actuator.
  • a Bowden wire or flexible cable will be understood to comprise a linearly movable flexible core surrounded by a relatively incompressible flexible sheath. At one end of the assembly, the core is displaced relatively to the corresponding extremity of the sheath to transmit traction or pressure to the cable at the other end thereof.
  • the principal object of the present invention to provide a Bowden wire or flexible-cable system for operating a number of controlled elements from a common source whereby the disadvantages of earlier Bowden wire systems are avoided.
  • a Bowden wire having a plurality of sections with a continuous core and separated sheaths in which, intermediate two such sections, a coil spring surrounds the core and bears in opposite directions upon the confronting ends of the sheath sections in the region in which the sheath sections are subdivided, the actuating elements being correspondingly coupled to the ends of the sheaths at the subdivision.
  • a number of elements can be actuated by a single Bowden wire whose core passes through the entire assembly until it is anchored at its end to a final controlled element.
  • a Bowden wire which comprises a single throughgoing flexible core wire connected at one end to an actuating member and at its other end to a controlled member
  • a lever at each of the connection points with the actuated mechanisms, a lever is provided having a slot in which a pivot pin of the sheath or core is pivotally received, the pin having an axis transverse to the core and projecting laterially therefrom.
  • the slot may be open at one end to permit the pin to be inserted or removed conveniently.
  • the actuating system of the Bowden-wire assembly comprises a lever 13 fulcrumed at 13 to a support 13" with respect to which the wall 12 is fixed.
  • the lever 13 carries a bifurcated pivot 13a to which the core wire 1 is anchored so that, upon pivoting of the lever '13 in the counterclockwise sense, the core wire 1 is drawn in the direction of arrow A through the wall 12.
  • the wall 12 has a sleeve 2a threaded into it and clamped by a nut 2b and forms the fixed terminus of the initial sheath 2.
  • a ferrule 20 carrying a laterally projecting pin 2d which is swivela'bly received in a slot 10a of a lever 10 which is fulcrumed at 10b to a plate 7.
  • the latter represents a floating housing or support structure, e.g., of an automatic vehicle brake, whose levers 10 and 11 are, upon movement of their free ends toward one another, designed to urge respective brakeshoes against, for example, a brake disk straddled by a floating yoke carrying the brakeshoes. Any other mechanism may be actuated in a corresponding manner.
  • the lever 11 is fulcrumed at 1111 on the floating plate 7 and has .a slot 11a in which a similar laterally projecting pin 3d is fitted.
  • the pins 2d and 3d can be readily removed from the slots 10a and 11a which open away from one another.
  • the pin 3a is formed on a ferrule 30 anchored to the sheath section 3 which, at its opposite end 3', carries another ferrule 3c' whose pin 3d is removably received by the slot 9a of a lever 9.
  • a second mechanism 6 is provided for simultaneous and essentially uniform actuation by the cable and comprises two traction-actuable levers, e.g., levers 8 and 9, which are fulcrumed at 8b and 9b to the plate 6.
  • the levers 8 and 9 have slots 8a and 9a opening away from one another and respectively receiving the pin 3d of sheath 3 and a laterally projecting cylindrical pin 14d.
  • the latter is carried by a ferrule 14c press-fitted onto the core wire 1 at its free extremity 14.
  • a control system for the concurrent actuation of two mechanisms each having a pair of relatively movable members adapted to be shifted for control thereof, said system comprising a flexible Bowden cable having a core wire anchored to one of the members of one of said mechanisms, a bent first sheath section extending from an actuatable end of said core wire to one movable member of the other of said mechanisms and anchored thereto at an end of said first sheath section distal from said end of said core wire, the end of said first sheath section proximal to said end of said core wire being held stationary with respect to said movable members, and a bent second sheath section surrounding said core wire while connecting the other members of both said mechanisms; and actuating means engageable with said end of said core wire.
  • control system defined in claim 1, further comprising a compression spring surrounding said core wire between said sheath sections and bearing thereon in opposite directions.
  • control system defined in claim 2, further comprising a compression-type spring surrounding said core wire and bearing upon the first-mentioned one of said members and said second sheath section for yieldably resisting relative displacement of the movable members of one of said mechanisms.
