Definitions

  • the subject-matter of this invention consists of a geared linear actuator, particularly well-suited for opening/closing windows.
  • actuators must also be capable of operating win­dows of various shapes and types, entailing a wide range of actuators of different shapes, sizes, travel and type of constraint.
  • the purpose of this invention is to create a highly reliable actuator, with great flexibility of use. This would mean lower costs, as one single type of actuator could be used for windows with very different sizes and characteristics.
  • the actuator according to the invention has an elongated prism-shaped housing containing a remote-controlled electric motor capable of interlocking with any type of automatic or manual control.
  • the motor in question controls the rotation of a threaded bar posi­tioned on an axis parallel to the longest side of the prism-shaped housing of the actuator.
  • a threaded bar posi­tioned on an axis parallel to the longest side of the prism-shaped housing of the actuator.
  • an internally threaded hollow rod is screwed which cannot rotate freely but can move freely axially.
  • One end of the internally threaded hollow rod passes through one of the ends of the prism-shaped housing and is equipped with an eye-bolt, to be secured to the window to be moved, in one direction or another.
  • said housing has on two parallel sides a pair of dovetail-shaped grooves.
  • One or two correspondingly shaped anchor bolts can be fixed into these grooves.
  • Stop screws are also fitted inside the actuator housing.
  • 10 is the elongated prism-shaped housing of the actuator.
  • This housing has two sides 11 and 12 on which there are lengthwise dovetailed grooves 13 and 14.
  • the housing also has a top side 15 and a bottom side 16.
  • the actuator housing can be positined in any direction, and therefore the terms “side”, “top” and “bottom” refer only to the positioning of the drawings.
  • the housing 10 of the actuator has two ends 17 and 18.
  • the first, 17, conventionally called the "rear” end has a sleeve for the power cable of the electric motor 20.
  • the other end, 18, conventionally called the “front” end also has a hole fitted with a bushing 21 through which the internally threaded hollow rod 22 passes.
  • the in­ternally threaded hollow rod 21 terminates with a transverse hole 23 to connect the rod to the mobile win­dow to be operated.
  • the motor 20 is supported by a diaphragm 24, equipped with a hole 25 through which the hollow rod 22 passes and a second hole 26 for the shaft of the electric motor 20.
  • gears of a reduc­tion unit formed, in the case illustrated in the drawings, by the gear wheels 30, 31, 32, 33, 34 and 35, arranged in series so as to achieve a triple reduction.
  • the last gear wheel, 35 is shrunk onto a threaded rod, 49.
  • a pair of limit switches one of which is indicated as 41 in figure 3, allows rotation of the motor 20 to be halted automatically, and thus axial movement of the hollow rod 22 in one direction or the other.
  • an anchor bolt 50 equipped with a complementary dovetail groove may be inserted into one of the two grooves 13 or 14. The anchor bolt may then be secured to the window frame.
  • the anchor bolt 50 may in turn be secured to a bracket 51, at any rela­tive angle, by means of a screw 52.
  • the anchor bolt 50 may also be secured to the support 51 in a manner allowing free rotation, so that the unit formed by the housing 10 and the rod 22 behave towards the mobile window like the swaying elements of a jointed frame with a certain degree of freedom.
  • bracket 51 may even be a U-shaped support, as shown by the dashed lines in figure 6.
  • the electric motor 20 may be either of the d.c. powered type or of the a.c. powered type. In the former case, it will be fed with a low voltage from stand-by batteries.
