Definitions

  • a device for automatically controlling the closing of a motor vehicle or tramcar window or the like characterized in that the movements of the movable sash frame carrying the glass in the upper half of the window port or aperture are pneumatically effected, the device also including a locking assembly for stopping the movable frame at any desired position.
  • This invention relates to a pneumatic device by which a window of a motor vehicle, tramcar or the like can be wholly or partially closed by locking the movable frame carrying the glass at any desired position.
  • a further object of the invention is to provide a device of this kind whose operation requires less compressed air from the reservoir which the vehicle is provided with.
  • a still further object of this invention is to provide a device requiring a minimum of maintenance.
  • the device according to the present invention being characterized in that the displacements of the movable sash-frame carrying the glass forming the upper half of the window are pneumatically effected, the device also including a lock assembly adapted to stop the movable frame at any desired position.
  • FIG. 1 is a front view, partially broken away, of a window incorporating the device according to the present invention
  • FIG. 2 is an enlarged sectional view of a detail for an upright of the fixed frame
  • FIG. 3 is a front and partially sectional view of the lock assembly forming part of the present device
  • FIG. 4 is a cross-section of the assembly in FIG. 3 taken along line 44 of said figure.
  • the window incorporating the device according to the present invention is provided with a fixed frame 3, which at the lower portion firmly holds the glass 4 forming the lower half of the window.
  • a sealed chamber 8 of a circular cross-section extends around the lower half of the fixed frame 3 and two hollow pistons 9 are sealingly slidable within the vertical sections of said chamber, each of said pistons having its bottom 11 at the top.
  • a slidable seal is provided by gaskets 10.
  • a second chamber 18 extends around the upper half of the fixed frame, the internal cross-sectional dimensions thereof being larger than those of chamber 8.
  • Pistons 9 move upwardly into the vertical sections of this chamber 18 along the uprights of the upper half of the fixed frame 3.
  • a slot in the vertical section of each chamber 18 permits an arm 7 on piston 9 to slide vertically.
  • Such an arm 7 projecting from each piston 9 connects said piston 9 at its bottom 11 to the movable frame 5 carrying the glass 6, said frame 5 forming a movable sash in the upper half of the window.
  • the projecting arm 7 ends in a fork and is connected to the movable frame 5 through a pin 5a projecting from the latter.
  • the end of a return spring 12 is connected internally to the bottom 11 of each piston 9, the other end of said spring being anchored externally of the mouth of said piston 9 to a pin 12 in the frame 3 positioned transversely of chamber 8.
  • a conduit 27 is adapted to convev compressed air from a reservoir of the vehicle or car into chamber 8. Between conduit 27 and chamber 8 a valve controlled by push-button 26 controlling entry of air in said chamber 8 is inserted.
  • a valve, controlled by push-button 25, is adapted to outwardly exhaust the compressed air in chamber 8 through a conduit (not shown).
  • Said lock assembly designated as a whole at 30, is substantially within the horizontal section of chamber 18 of the fixed frame 3 and includes a finger 31 pivoted at 32 to a support 33 integral with frame 3 and connected through a cable 34 to an overriding element 28, which is connected in any suitable manner to the push-button of valve 25 exhausting the air from chamber 8; cable 34 travels within chamber 18, hence within the groove of a pulley 35, the axis of which is arranged transversely of chamber 18 adjacent an upper angle of frame 3 and then within a peripheral channel 41 around the frame 3.
  • Lock assembly 30 also includes a rack 36, slidable Within the upper horizontal section of cavity 41 and having an end connected through a cable 38 to bottom 11 of one of said pistons 9 and the other end connected to an end of a return spring 39, also accommodated within cavity 41 and the other end of which is anchored by a pin 37 to frame 3 at an end of the upper horizontal section of said cavity 41.
  • Cable 38 runs within said channel 41 into the groove of a pulley 40, the axis of which is positioned transversely of cavity 41 adjacent the other upper corner of frame 3.
  • a latch 43 is pivoted by pin 42 on support 33, said latch 43 being provided with an extension 43a, which is engaged by finger 31 to disengage the pawl 43b from the teeth of the rack 36 against the force of a spring 44.
  • pushbutton 25 When it is desired to open the window, by completely or partially lowering the movable frame 5 carrying the glass '6, pushbutton 25 is pressed so that the valve con trolled thereby will cause the whole or part of the com- 3 pressed air in chamber 8 and pistons 9 to discharge outwardly.
  • Tension of cable 34 will cause the finger 31 to rotate about pivot 32 so that, owing to the action of finger 31 on the extension 43a of latch 43, the latter will-be rotated about pivot 42 against spring 44, and thus the pawl 43b thereof will release the rack 36.
  • rack 36 can move freely as well as pistons 9 and frame 5.
  • lock assembly 30 assumes again the inoperative position at which latch 43 engages rack 36 at any notch thereof and, as a result, the above-mentioned locking is restored.
  • a device for controlling the sliding movement of the sash frame of a motor-vehicle or tramcar window or the like in a stationary window frame comprising a sealed chamber of circular cross-section extending around the lower half of the frame and having parallel end portions in the sides of said frame, an elongated pist s alingly slidable into and out of the parallel end portions, a second chamber extending around the upper half of said frame and having inverted parallel end portions positioned in alignment with the end portions of the sealed chamber to receive the two pistons during their movement out of the sealed chamber, the inverted parallel end portions being slotted along their lengths adjacent the movable window, a horizontal arm carried 'by the upper end of each piston and extending through one of the slots to engage an edge of the window to raise or lower the same, air inlet and exhaust valves for admitting or exhausting air into or out of the sealed chamber, a slidable rack with inclined teeth in the middle of the second chamber, a flexible cable connecting one end of the rack with the upper end of
  • a device for controlling the sliding movement of the sash frame of a motor-vehicle or tramcar window or the like in a stationary window frame comprising a sealed chamber of circular cross section contained in the lower half of the stationary window frame, a second chamber contained in the upper half of said stationary frame and of larger cross section than the sealed chamber, an elongated piston sealingly slida'ble in each end portion of the sealed chamber and movable into the ends of the second chamber, the end portions of the latter being longitudinally slotted, a laterally projecting arm on the upper end of each piston extending through one of the slots to engage an edge of the sash frame to raise or lower the window, and a locking assembly in the stationary frame and extending into the second chamber for stopping the movable frame in any desired position.
