Definitions

the invention involves door actuator, including but not limited to actuator of doors of transport means, changing the straight movement of the double-action pneumatic cylinder to rotational movement needed for door opening and closing.
the so far used actuators consist of two hollow cases inserted one into the other, changing the straight movement from the double-action pneumatic cylinder to rotational movement transferred onto the bar connected with the inner case controlling door opening and closing with the help of two opposite-oriented spiral grooves and carriers guided by the grooves.
This type of actuator is described for example in document CZ 243175.
Some known actuators include one pair of spiral grooves, usually longer by the outer case, with this extended part straight, parallel in the axial direction with the case axis, which enables protrusion of the door after closing in the straight direction upwards and allows for its locking with wedged segments against spontaneous opening, for example by the under-pressure resulting from the vehicle movement.
Such an actuator is described for example in document CZ 10699 U1.
all known actuators including those with transfer of straight movement to rotational movement with the help of a ball screw, cause a bounce to the door frame, especially in winter or on an uneven ground, causing insufficient tightness of the door and the frame sealing, for the wedged segments of the door not caught in the wedged segments of the frame.
Fig. 1 depicting the inner case with two grooves in a partial section
Fig. 2 depicting the unfolded shape of the inner case groove
Fig. 3 depicting the outer case with the extended grooves in a partial section
Fig. 4 depicting the unfolded shape of the outer case groove.
Fig. 1 shows the inner case 1 of the actuator in the shape of a hollow cylinder with two grooves 3 in the coating turned by 180 degrees in relation one to another, with the inner case 1 firmly fixed to the bar 7 controlling the door opening and closing.
Fig. 2 shows that the shape of the groove 3 is spatial curve whose tangent and the longitudinal axis are in the angle of ⁇ 1 in relation to each other.
Fig. 3 shows the outer case 2 of the actuator, also in the shape of a hollow cylinder, with two grooves 4 in the outer case 2 turned by 180 degrees in relation one to another.
the outer case 2 is provided with a flange 6.
Fig 4 shows that the shape of the groove 4 is spatial curve whose tangent and the longitudinal axis of the outer case 2 are in the angle of ⁇ 2 in relation to each other.
Both grooves 4 are provided with extensions 5 in contrast to the grooves 3 in the inner case 1, in the shape of spatial curves in the angle of ⁇ 3 with the longitudinal axis of the outer case 2.
the door does not only perform straight movement upwards under the wedged segments but also turn by the required angle determined by the construction of the door frame and the sealing. This is allowed by the two grooves in both hollow cases in the shape of spatial curves - most often spirals.
Both the outer and the inner hollow case have the two grooves turned by 180 degrees in relation to each other.
the grooves of the outer case are oriented opposite the inner case grooves.
One of the pair of grooves is extended in the axial direction by a value within the range 1 - 30 mm. This extension, however, is in an angle related to the vertical axis different from the previous section of the curve. This extension is most conveniently implemented in the outer case grooves.
the compressed air acting in the bottom part of the pneumatic cylinder exerts force on the piston inside the cylinder and the piston begins to rotate and move straight upwards.
the moving piston rotates the inner hollow case in relation to the outer hollow case, which is fixed and cannot rotate.
the carrier in our case the needle bearings, begin to roll away in all four grooves of both cases, with the inner case transferring the rotational movement onto the bar controlling the door opening and closing.
the inner case must be secured against axial shift with a settable reaction force.
Mechanical spring is conveniently used for generation of this force.
