Embodiment Construction

[0029] figure 1 The rotating wing door 100 according to the present invention is schematically shown. It can be seen here that the rotating wing door is a door panel 110 that can be opened to both sides. The door panel 110 can now be moved upwards from the closed position S to the first open position O, or downwards to the second open position O. The movement area between the closed position S and the corresponding open position O is called the open area B. It can also be seen that this movement is carried out in a limited rotation supported by the supporting device 120. A door closing device 10 is arranged on the door panel 110, which is constructed in a manner according to the invention. The door closing device is used to apply the corresponding closing force and opening force to the door panel 110 through the torque joint 20.

[0030] Figure 2a to Figure 4b A first embodiment of the door closing device 10 according to the present invention is shown. The door closing devic...

Abstract

A door closing device (10) is used for rotating a door plate (110) of a rotary wing door (100); the door plate can be supported in an open zone (B) between a close position (S) and at least one opening positions (O); the door closing device comprises a torque joint (20) connecting with the door plate (110) in torque transmission , a closing spring (30), and an opening spring (40); the closing spring applies a closing force (SK) to the door plate in a closing position (S) direction through the torque joint (20); the opening spring applies an openign force (OK) to the door plate in an opening position (O) direction through the torque joint (20); the opening spring (40) comprises an adjusting device (42) used for adjusting the opening force (OK). A low cost and simple mode is used, so the door closing device can ensure a high usage flexibility, adjustability of the spring of the door closing device, and easy opening operability.

Description

Technical field [0001] The present invention relates to a door closing device used for a door panel of a rotating wing door and a rotating wing door having the door closing device. Background technique [0002] It is well known to design rotating wing doors with door closing devices. In this case, the swing flap door can be moved in the open region between a closed position and at least one open position. In the closed position, turn the wing door to close the door opening. In the open position, the swivel wing door is open so that a person can move through the door opening. The known rotating flap door can be moved to the second open position on one side or on both sides. In order to be able to provide automated closing of the swing wing door in the known swing wing door, a mechanical door closing device is known. Mechanical door closing devices are usually equipped with a spring device that is tensioned to the open position when the door is opened. This means that during t...
