Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an adjustment device for a motor vehicle door which is pivotably mounted on a door post on the day side and which adjusts the interior handle and the outside handle. between the door post and the door, the piston-cylinder unit comprising a piston having a through hole for the pressure medium. and in which the piston is adapted to cooperate with an internal valve which separates the two working chambers of the cylinder from each other.

BACKGROUND OF THE INVENTION A locking device for flaps, doors, etc. in a motor vehicle with a piston-cylinder unit is known from German Patent Application No. 2,555,062. The piston-cylinder unit has an outlet in the piston that can be closed by a closing member, thereby locking the device. In such an arrangement, especially when used for a motor vehicle door, the pressure force acting on the flap, i.e. the closing force, causes the medium pressure acting on the closing member to be very high, so that the closing member moves away from the piston and the medium pressure is increased. The disadvantage is that flow occurs and the flap loses its locking position. Therefore, when an external force acts on the flap, door, etc., it is not possible to maintain a constant opening angle with this type of device.Problems to be Solved by the InventionAn object of the present invention is to hold the door at any intermediate position. The object of the present invention is to construct an adjusting device of the type mentioned at the outset in such a way that it is lockable and, moreover, allows the door to be opened and closed easily.

Means for Solving the Problem The means of the invention for solving the problem described above is such that, in a regulating device of the type mentioned at the outset, the regulating device is provided with a locking valve for controlling the medium flow; is cylinder 2
The locking valve is arranged so as to act in a direction opposite to the flow direction in a control circuit connecting two working chambers, and the locking valve is arranged to act in a direction opposite to the flow direction, and the locking valve is arranged in such a way that the door can be locked in at least one intermediate position. be configured to be controlled by the door handle.

The exemplary adjusting device 1 essentially comprises a cylinder-cylinder unit 2 . The piston-cylinder unit 2 has a control circuit 3 in which locking valves 4; 4a; 4b are arranged.

This locking valve can be arranged either internally or externally of the cylinder cylinder unit 2. The piston-cylinder unit 2 is held between the door 5 and the door pillar 6 on the body side so as to be pivotable about a vertical axis 7°7a,
Moreover, the piston rod is connected to the hinge mechanism 22 of the door 5. When the door 5 is pivoted in the direction indicated by the arrow 8a (opening), the piston 9 of the histone-cylinder unit 2 moves in the direction indicated by the arrow 10 and the door 5 is pivoted in the direction indicated by the arrow 8. When forced (closed), the kisston 9 moves in the direction indicated by the arrow 11. According to FIG. 2, the piston 9 of the piston-cylinder unit 2 has a through opening 12 for a pressure medium, such as gas, oil, etc. In the configuration according to FIG. 2, the outlet 12 is opened or closed by an internal valve 13 which is controlled by a spring 14 in relation to the movement of the door. The conduits forming the control circuit 31 of the regulating device 1 open with an inlet and an outlet into separate working chambers 15 and 16 of the cylinder.

The locking valve 4 is arranged in the control circuit 3 so as to act in a direction opposite to the flow direction indicated by the arrow 17. The lock valve 4 is connected to the door handle 20.21 via a mechanical adjustment member 18 or an electrical adjustment member 19 (FIG. 6).
It is movable into a closed position A and an open position B in connection with the operation of the .

The locking valve 4; 4a; 41) is connected to an interior door handle 20 and an exterior door handle 21 via a mechanical adjustment member 18. The adjustment member 18 can be constructed by a rope device or a beaden cable. The locking valve 4 can be adjusted via the respective door handle 20.21 into an open position A and a closed position B (FIG. 2).

According to the embodiment shown in FIG. 6, 1 instead of the mechanical adjustment element 18 an electrical adjustment element 19 is used. For example, a switch can be actuated via the door handle 20.21, with which a solenoid valve forming, for example, the locking valve 4a is controlled.

According to FIG. 7, the locking valve 4b is also designed as a safety valve. The locking valve has a control surface 24 which is directed in the control circuit 3 towards a pressure medium column 25 .

According to another embodiment shown in FIG. 3, spring-loaded valves 13a and 13b are arranged on either side of the piston 9a. These valves are activated during the opening process of the door 5, when the piston 9a moves in the direction indicated by the arrow 10, and at this time the valve 131) moves away from the valve seat on the piston 9a.
It acts to open the through hole 12 (FIG. 4).

If strong pressure is not applied to the door 5 after this, the door 5
is kept open. Since the through-hole 12 is closed by the valve 13b, light adjustments are no longer possible. When the door 5 is closed, the valve 13a is separated from the piston 9, and as a result, the through hole 12a is opened. Valve 13a
By adjusting the spring force acting on and 13b, a light opening/closing operation is obtained, yet the door is locked in an intermediate position when opened and held even if pressure is applied.

The mode of action of the adjusting device according to the exemplary embodiments shown in FIGS. 1, 2 and 6 is as follows: The door 5 can be opened from the interior via the door handle 20 or from the outside via the door handle 21. When opening the door
・The handle is moved to the position indicated by the one-dot chain line. In this case, the locking valve 4 is moved in the control circuit 3 from the closed position A to the open position B via the adjusting element 18, 19. The two working chambers 15 and 16 are thereby connected to each other and pass the medium, so that the piston 13
corresponds to the movement of the door in the direction indicated by arrow 10. During this process, the opening 12 is closed by the valve 13. The medium is forced from the working chamber 15 through the open control circuit 3 into a further working chamber 16 . When you release the door handle 20.211, the door handle 2
0.21 again occupies the starting position indicated by the solid line. This closes the locking valve 4:4a; 4b and stops the flow of medium and therefore any further movement of the door in the opening direction. The door 5 can therefore be immediately locked in various intermediate positions.

A safety valve 4a is provided to prevent damage from occurring when the door in the locked position is attempted to be opened further by force. When a certain pressure is applied to the door, this valve 4a opens the control circuit 3, so that a further pivoting movement of the door is guaranteed.

To close the door 5, the door handle 20 or 21 is actuated, as a result of which the locking valves 4:4a:4b are re-opened, allowing the medium to flow through. Similarly, the door handle 2o or 21 is actuated. It is possible to lightly close the door 5 without opening the working chamber 16 by moving the piston 9 in the direction indicated by the arrow 11.
The medium inside is forced into the through hole 12 against the valve 13. The valve 13 moves away from its seat on the piston 9 against the load of the spring 14 and opens the through opening 12, so that an inflow of medium into the working chamber 15 takes place.

Effects of the Invention The main advantage achieved by the arrangement of the invention is that the door can be opened and closed easily when operated via the interior or exterior door handle, and each opening is performed immediately upon releasing the operated door handle. The locking of the door takes place in an angular position. This is particularly advantageous when the vehicle is parked in a narrow space, and avoids the door colliding with a vehicle parked next to it. Even if relatively strong pressures are applied to the door during exiting the vehicle, no change in position of the door occurs.In known devices, such forces can cause the door to move, but in the arrangement according to the invention this does not occur. This is also because the door cannot change its position even if a relatively strong force in the door opening direction is applied to the door.However, damage can occur when the force acting on the door is very large. If there is a locking valve configured as a safety valve, care is taken that at the same time the locking valve is opened and the door can be swiveled further; whereas it is always possible to close the door from the locked position; If the door handle is not used to close the door, the locking valve is opened via the door handle, and the internal valve is closed to allow medium circulation in the control circuit. In this case, the pressure of the medium acts on the internal valve, which opens this valve and allows the medium to flow from one working chamber to the other, so that the closing of the door is not prevented. It is done.

The mechanical and/or electrical connection of the lock valve to the interior or exterior door handle allows easy operation of the lock valve.

This connection serves such that the control of the valve takes place simultaneously with the handling of the door, so that an additional control device is omitted. Mechanical means for adjustment can be constituted by Bowden cables.
