Definitions

  • the present invention relates to a pneumatic jack device, applicable particularly to the opening and closing of pivoted members such for example as swing doors, barriers, trap doors and other analogues applications permitting a particularly simple and effective construction.
  • the complete opening of the pivoted element is caused by a single push exerted on it, initiating this opening, and it returns at once automatically to the closed position, after having attained its position of complete opening. Any new opening force, in the course of the return movement, brings about afresh the complete opening of the said member.
  • the device which is the subject of the invention makes use of the principle of toggle levers, in which one dead centre position is attained when the two arms of the toggle are in alignment.
  • one of the arms of the toggle is constituted by the pivoted member, and its other arm by a pneumatic jack placed in the plane of the latter, pivoting at one end at an intermediate point on the edge of the pivoted member, and at its other end on the case or frame of the opening in which the said member swings.
  • the invention concerns more especially a particular mechanism for control of admission and exhaust of the air or other compressed gas, incorporated in the jack for the purpose of obtaining the desired effects.
  • FIG. 2 is a corresponding plan view.
  • FIG. 3 shows the position of the components at the beginning of opening.
  • FIG. 4 shows the door completely open.
  • FIG. 5 is a view partly in elevation and partly in longitudinal section of the pneumatic jack used, and of the control mechanism which it contains.
  • a pneumatic jack 4 the rod 5 of which carries at its end a swivel head 6, attached at a suitable point to the upper edge of a door leaf 7 which pivots on hinges 8 against the action of torsion springs 9 which tend to keep it shut.
  • the air admission valve being automatically closed and the torsion springs 9, stressed by the opening of the door, ensure its return to the position of complete closure, in step with the exhausting of the air contained in the cylinder of the jack, and escaping from it through an adjustable opening.
  • FIG. 5 The mechanism providing for these operations, constructed according to the invention and incorporated into the jack, is schematically shown in FIG. 5,. and will now be described in detail.
  • the rod 5 of the jack carries a sleeve 1&1 tightened but sliding on it, and the tightness of which is adjustable by use of screws 11.
  • the chamber 15 of an inlet valve with a ball 16 loaded by a spring 17.
  • a longitudinal pusher 18 permits the sleeve 10 to act on the ball 16 to displace it from its seat. This pusher slides with slight friction in a bore 21, into which open two radial openings 22 and 23.
  • a needle valve 24 permits precise adjusting of the cross section of a passage 25 connecting the radial opening 23 with the interior of the cylinder of the jack, the wall 26 of which is pierced by a vent 27 in communication with the exterior.
  • the compressed air arrives in the chamber 15 through the pipe 28.
  • Another pipe 29 puts the radial opening 22 into communcation with a passage 30 provided in the base 31 of the cylinder of the jack, the piston of which is indicated at 32.
  • the piston rod 5 includes a portion 33 of reduced diameter, and preferably slightly conical, the length of which corresponds to that of the sleeve 10, the return travel of which is limited by an abutment 34, fixed to the cylinder.
  • This rod carries with it the sleeve 10, which, via the pusher 18, displaces the ball 16 from its seat, at the same time as this pusher closes off the radial opening 23.
  • the compressed air is thus admitted into the bore 21 and, making use of the opening 22, the pipe 29 and the passage 30, it arrives behind the piston 32, which it displaces to cause the complete opening of the door (see FIG. 4).
  • the reduced diameter portion 33 provided on the rod 5 reaches a position abreast of the sleeve 10, the grip of which is thus nullifed.
  • the pusher 18 then ceases to act on the ball 16, which by the pressure of the compressed air, to which is added the force of the spring 17, is returned to its seat, thus cutting off the supply of compressed air behind the piston 32.
  • the pusher is displaced towards the left in FIG. 5, making Q the sleeve 10 return until it is stopped by the abutment 34, at the same time as it uncovers the radial opening 23.
  • the compressed air enclosed within the cylinder 26 behind the piston 32 passes to the exterior by making use of the path 30, 29, 22, 21, 23, 25, and 27, the speed of closing of the door, produced by the torsion springs 9, being able to be controlled by adjusting the needle valve 24.
  • hinge means mounting said member on said frame, whereby to enable said member to pivot through said opening in both directions from a closed position wherein said member lies in the plane of said frame,
  • actuating means for said member comprised of (a) a pneumatic jack including a cylinder, a piston and a piston rod extending from one end of said cylinder, said cylinder and piston rod movable apart by the admission of operating medium to said cylinder,
  • an air inlet valve associated with said jack and including a seat, a valve member and a valve spring urging said valve member against said seat,
  • said piston rod including a second portion of reduced diameter spaced from said first portion and enabling friction between said sleeve and piston to be nullified when said rod attains a
  • a device as claimed in claim 1 including an abut.-
  • a device as claimed in claim 1 including a head mounted on the jack cylinder and enclosing the air inlet valve, said head defining a bore providing guidance for said pusher and terminating at the valve seat, and defining a passage extending from the interior of the cylinder to an opening in the side of said bore, said pusher including a portion adapted to act as a slide valve controlling said opening.
  • a device as claimed in claim 4 including an abutment mounted within the jack cylinder adapted to limit travel of the sleeve away from the valve member, and a wall enclosing the cylinder and defining a vent from the interior of the cylinder to the exterior at a place between the cylinder head and the abutment.
  • a device as claimed in claim 4 including a pipe connecting the cylinder head to the end of the cylinder remote from the head, the head defining a second opening in the side of the bore in communication with the pipe.
