Definitions

  • the present invention refers to a door opening and closing device, which enables very easily adjusting final damping of the opening and closing path.
  • damping means have been included in the fluid dynamic cylinder, that slow down the door movement in its final opening or closing stretch. In this way, the door gently opens or closes, without causing noise.
  • the door opening and closing device of the invention comprises a fluid dynamic cylinder for driving the door opening and closing movement and means for damping said movement when the door nears its final open or closed position, and it is characterised in that said damping means comprise a telescopic body and a moveable thrust washer on the rod of said fluid dynamic cylinder, said washer being able to be fixed on said rod in the desired position, so that when said washer abuts with the telescopic body, it moves it and damps the door opening or closing movement.
  • the device of the present invention also has an anti-wind effect, so that when the door is open, the damping itself with the telescopic body, contracted by the stop washer, brakes the motor, preventing the wind from closing the door.
  • the closing manoeuvre is carried out with a slower movement whilst the telescopic body is contracted. This fact is very beneficial, as it gives warning of the closing manoeuvre.
  • said telescopic body also has elastic means associated, which prevent movement of same, so that when the washer abuts with said telescopic body, the latter moves against the action of said elastic means.
  • said damping means include a single retaining needle provided with a couple of fluid inlets, a first inlet that is connected to the fluid supply through a fluid chamber and a second inlet that is connected to the fluid supply through a pipe that passes through said telescopic body, so that when the washer is not in contact with the telescopic body, the fluid goes through same entering into the retaining needle through the two inlets, and when the washer abuts with the telescopic body and moves it, the passage of fluid through the telescopic body is stopped and fluid only goes into the retaining needle through the first inlet, decreasing the rod displacement velocity.
  • Figure 1 is a cross-sectional view of the fluid dynamic cylinder at the moment of opening or closing the door.
  • Figure 2 is a cross-sectional view of the fluid dynamic cylinder at the moment of damping the door opening or closing movement.
  • the damping means of the opening and closing device of the present invention include a fluid dynamic cylinder, generally identified by the numerical reference 1 provided with a rod 4 and a piston 12 joined to same that moves inside its chamber 13.
  • the damping means also comprise a fluid circuit, which includes from a fluid inlet pipe 9 to said chamber of the cylinder 13. Said circuit also comprises a retaining needle 6 and a fluid chamber 10, whose function will be described below.
  • the damping means also comprise a telescopic body 2 which is movable in the direction of the rod 4, a spring 5 associated to said telescopic body, and a thrust washer 3 placed on the rod 4 and which is movable on same.
  • This washer 3 can be fixed in any position of the rod 4 and is what determines initiation of the reduction in the door displacement velocity when it is opened or closed.
  • the retaining needle 6 is positioned between the fluid feed pipe 9 and said chamber of the cylinder 13.
  • This retaining needle 6 comprises a first fluid inlet 7, connected to the feed pipe 9 through a fluid chamber 10, and a second fluid inlet 8, connected to the feed pipe 9 through a pipe 11 that passes through the telescopic body 2.
  • the door opening and closing device of the present invention works in the following way.
  • Figure 2 shows the final position of the telescopic body 2, which corresponds to the door totally opened or closed position. As shown by this figure, the telescopic body 2 blocks the entry of fluid into the chamber 10, preventing the entry of fluid into the retaining needle 6 and the chamber 13, stopping the movement of the piston 12 and the rod 4.
