Description
Technical field
The present invention relates to a kind of door closing device of the door-plate for rotating flap door and a kind of rotation flap door with this door closing device.
Background technology
The rotation flap door that design has door closing device is known.Rotate flap door to move in opened areas between fastening position and at least one open position at this.In a closed position, rotate flap door and close door opening.In the open position, rotate flap door and open, thus people can move through door opening.Known rotation flap door can one-sided or also can move to the second open position in both sides.In order to provide the closedown of the automation of rotating flap door in known rotation flap door, mechanical type door closing device is known.Mechanical type door closing device is furnished with spring assembly usually, and this spring assembly is tensioned to open position when door is opened.This means, opening between moving period from fastening position to open position, the spring of spring force owing to improving and tensioning must be overcome.Usually distribute linearly for the corresponding torque condition of rotating flap door.According to form and the type of the rotation flap door existed, different pretensions or different spring characteristic curves can be important for door closing device.Therefore, be well known that equally, adjustable ground designs corresponding spring assembly, thus spring is installed with different pretension values.
In known door closing device disadvantageously, door closing device uses possibility only to have very little flexibility about it.Although adjusting device provide in principle spring assembly for close or for the change of pretension in the closing forces of rotating flap door, still obtain almost power state linearly at this.This means, when the pretightning force for required larger closedown moment improves, along with larger closing forces is automatically along with the more difficult operability of rotating flap door.If improve pretension for the closing forces of corresponding spring assembly, correspondingly so therewith also must use larger power, just to make rotation flap door move from fastening position along the direction of open position when opening motion and starting.Especially, at the application target requiring light operation, such as, in nursing home, creche or in the region in disabled person apartment, the motion of this difficulty is less desirable or forbids even in principle.Therefore, the known door closing device with adjustable spring assembly also cannot be used in these sensitizing ranges, and it uses flexibility to suffer a loss thus.
Summary of the invention
The problem that task of the present invention is described before being elimination at least partly.Task of the present invention especially realizes the controllability for the spring assembly of door closing device in the use flexibility situation high as far as possible of door closing device in cheap and simple mode.At this, especially achieve the use possibility with easier opening operation.
Foregoing task is solved with the rotation flap door of the feature with claim 9 by the door closing device with the feature of claim 1.Other characteristic sum details of the present invention is learnt by dependent claims, manual and accompanying drawing.At this, be obviously also be applicable to combine according to rotation flap door of the present invention in conjunction with the characteristic sum details described by door closing device, and correspondingly vice versa, thus disclosing in each is of the present invention always can reference mutually.
In door closing device according to the present invention, door closing device is configured to the door-plate rotating flap door, and this door-plate can support with moving in opened areas between fastening position and at least one open position.For this reason, door closing device have for the torque fitting that is connected of door-plate moment of torsion transmission ground.In addition, be also provided with closedown spring, it loads closing forces towards the direction of fastening position to door-plate by torque fitting.Extraly, be also provided with and open spring, it loads tensile force towards the direction of open position to door-plate by torque fitting.At this, open spring and there is adjusting device for regulating tensile force.
Except the embodiment of known door closing device is provided, the combination having two springs arranged according to the present invention.These combinations apply the power acted on along different action directions by torque fitting on door-plate.That is, closing spring causes door-plate to move to fastening position.Meanwhile, open spring, for utilizing its tensile force, door-plate is moved to open position.First, it is unessential for being in which kind of orientation at this corresponding spring.Importantly, what such as produce tensile force and closing forces by lever motion mechanism or reverse lever has the respective action associated that is this and door-plate.
Open spring and close spring and can be understood as following spring assembly in principle, it has flexible and correspondingly along the deformability that spring characteristic curve is possible.At this, this spring assembly can be such as helical spring.But in meaning of the present invention, for constructing corresponding spring, namely close spring and other elastomeric material of opening spring is also feasible.
That is, in door closing device according to the present invention, open spring for two and act on relative to each other, thus the power state on door-plate or torque condition are produced by the combination of two spring forces.At this, especially in the forefoot area of opened areas, namely when door-plate has just left or left fastening position, motion is opened in tensile force support.When moving to open position from fastening position, tensile force reduces, and reaches null value when arriving open position especially the latest.Meanwhile, close spring and move to open position for hindering from fastening position.Closing forces is improved to open position from fastening position by the raising of closing the pretension in spring.In other words, two springs relatively work, although thus have desired pretension, still with very high efficiency in the open position by opening the support in front opening region that spring carries out in the region of fastening position.Thus, such as the high pretightening force for closing spring can also be provided by the second adjusting device.By by by the support of opening the tensile force that spring produces, although have very high closing forces, still can realize light operation when leaving fastening position, this is because at this, door-plate existing the torque condition obviously changed.Closing torque correspondingly reduces with the open torque provided by the tensile force opening spring.Achieve in like fashion for leave fastening position easy operability and simultaneously by the combination of the high reset force of the closedown spring in an open position.Therefore, also can be used in light operability in responsive use region according to door closing device of the present invention.However, being equipped with this shutoff device still can to very heavy door-plate, that is however, still can selecting high pretightening force for open position by closing spring thus.That is, exist in rear opened areas for the common of door-plate and especially also expect open damping or reset feature.
The adjusting device opening spring opens supportive device and and then the portability of door-plate for regulating now.Therefore, spring is opened with its adjusting device for providing the opening characteristic being matched with corresponding using state.If open spring by pretension, strengthen the tensile force in fastening position so on the one hand, and increase on the other hand open spring via its also practical function to the path on door-plate.Reduce in tensile force by adjusting device if open spring or even keep not having pretension, so this is opened spring and is substantially disconnected, thus no longer carries out opening support now.Can be regulated arbitrarily opening on spring now by adjusting device, thus use possibility flexibly by selecting the corresponding pretension opening spring can realize the special of door closing device.Except with except the known use possibility of normal application target on door-plate, according to door closing device of the present invention by using the easy operability opened spring and the corresponding adjustment in adjusting device and also may be used under responsive using state.Due to the flexibility improved, the minimizing of the cost that the number of packages owing to improving each single component causes can be realized.
