Reset device for swing gates

The invention relates to a reset device for swing gates.

Swing gates are used to close corridors, storage rooms, factories and the like. They usually consist of A one-sided (gallows-shaped) frame structure, in which a soft material such as rubber, plastic or the like. In Is hung in the form of a film. You must after both se "] can be opened and must be opened again after opening can close automatically, i.e. swivel back into their starting or rest position.

Various resetting devices for swing gates are already known in which a torsion spring is used, the two effective ends of which each open into a leg. A stop is provided between these two legs, so that each leg can only rotate in one direction, namely against the force of the spring. In one embodiment Such a return device sits the torsion spring in the vertical spar of the frame structure of the swing gate. Their effective ends are over dinen bolts or a bushing

is fixed in place, for example on a ceiling beam. When the swing gate opens, one of them supports himself Leg on the stop, while the other leg is rotated by the swing gate against the spring force. This Leg then exerts the restoring torque on the gate.

A significant ¹ disadvantage of the construction described above is that the space around the swing axis of the Pendeltors, namely the space in the vertical beam and is fully filled immediately above it by the spring mechanism, and can not be used for further control measures for the disposal more.

In another construction, a similar torsion spring mechanism is provided between the vertical wall of the swing gate and the wall surrounding the swing gate

Both constructions have the common disadvantage that the restoring force increases with increasing door opening - corresponding to the greater spring deflection will. This can even mean that when driving through the Swing gates with a transport vehicle the swing gate filling ΐΓ-οΐϊ their elasticity se strong on the sides of the transport = vehicle grinds, because it is ε ^ echädigx or slips off parts to be transported from the transport vehicle.

"The invention is based on the object of providing a reset To create a device for swing gates, which can bring about a freely selectable course of the restoring force depending on the gate opening angle.

This object is achieved by the features specified in the characterizing part of claim 1.

With the reset device according to the invention, the following balance of forces occurs when the gate is opened: The force% pushes in the direction of the horizontal gate post on the backdrop. The reaction force emitted by the backdrop can only be perpendicular to its surface, i.e. in

Χ- ΐ act in the direction of their normal. By vector addition of these

two forces results in the resulting restoring force, which is due to the fact that the normal of the backdrop in front of the Torpenael axis passes, acts in the direction of the door closed position. The backdrop has a symmetrical shape, with its center being the gate closed position is equivalent to. The resulting restoring force therefore always acts in both opening directions Direction to the closed position.

The backdrop can run out so far that door opening angles of more than 190 ° (up to approx. 170 °) can be detected. where the desired restoring force still occurs.

Advantageous embodiments of the reset device according to the invention are specified in the subclaims. In the embodiment according to claim 3, the role is running open the gate over a predetermined angle into the recess. Since a resulting restoring force is switched off, the gate remains in the one corresponding to the recess In the open position without it swinging back automatically This is advantageous when it is desired to keep the door open at all times - for example, to ventilate a room Factory hall on hot summer days. The angle at which the recess is made in the backdrop can be chosen in such a way that that it corresponds to an extremely open position of the gate,

which is not reached with normal gate opening. Through this the door closes automatically if it is opened in the usual way - i.e. not up to the extreme opening angle will. To lock the gate in the off setting you need then only to pivot it beyond the usual opening angle into the extreme opening angle.

It should be noted that simply making a depression in the backdrop is a particularly simple measure represents to achieve a gate lock in a certain open position.

By choosing the shape of the backdrop, the direction of its normal to the curve and thus the direction of the reaction force emitted by its surface can be determined as desired. In the embodiment of the restoring device according to the invention according to claim 4, this reaction force goes more and more in the direction of the spring force exerted via the roller with increasing opening angle, so that the resulting restoring force becomes smaller and smaller. Preferably, a non-linear relationship between the door opening angle and the restoring force is selected such that a relatively high initial return torque occurs, while after exceeding a certain minimum opening angle, e.g. B. 15 °, is significantly smaller to with a fully open door (opening angle 90 °)

741) 0397

to become minimal · Due to the high initial self-aligning torque achieves that the door cannot be opened by air pressure, while the low restoring force at fully open gate prevents damage to the gate panel or hinders the passage of the gate.

In the embodiment of the reset device according to the invention according to claim 5 sits: the link on a Bearing plate that is firmly connected to the building, for example a cross member. The backdrop is screwed to this bearing plate, and through it goes one with the bearing plate permanently connected bearing journals seated in the pivot axis of the door. The screwing of the backdrop with the bearing plate takes place in such a way that the link relative to the bearing plate can be rotated around the gate pivot axis. This can be achieved, for example, by means of slotted holes (in arched shapes). Due to this rotatability of the backdrop, the door closed position adjusted. On the one hand, you can thus achieve an exact (^ -closed position, while on the other hand you can also set any zero position in which the gate assumes a pre-opening angle, which can be advantageous if the Tcr generally only traverses in one direction will.

The bearing pin protrudes into a bearing bushing at the end of the vertical door beam "or" the door is with the vertical one

Torholm placed on this bearing pin.

Since the swing gate usually only has two spars, namely the vertical spar lying in the pendulum axis and the horizontal bar arranged on its upper side, the reset device is normally on the upper side attached to the fender gate.

In the implementation of the reset device according to the invention according to claim 6, the bearing pin is secured by means of a pin against slipping out of the bearing bushing into the vertical gate pillar. Of course, the vertical gate post is also located in a warehouse at its lower end. The securing of the swing gate from slipping off the bearing pin is used in the event that the vertical spar is accidentally (forcibly removed from its lower bearing, which would easily be possible if the vehicle were driven hard against it).

Through said fuse is prevented in such a case "daft the shuttle gate total fall over and cause any damage.

The invention is explained in more detail below with reference to schematic drawings of an exemplary embodiment.

I fig 1 shows a sectional view of an embodiment

I form of the reset device according to the invention;

and

Fig. 2 shows a partial section according to L.i / iie II-II in Fig. 1.

As shown in FIG. 1, the embodiment shown there has the reset device according to the invention a roller 1 and a gate 2 .. The gate 2 is by means of a 14 indicated screw on a bearing plate 6, which in turn is firmly attached to a building part 13, for example a ceiling beam.

I On the backdrop 2, the roll 1 rolls off »that of one

jj fork 3 is held, which is piston-like at its end

* is stalten and protrudes into a socket 4, which is connected to the

i the horizontal spar 15 of the swing gate is permanently connected *> n. In

the socket ** sitst a compression spring 5, the fork 3 and j so that the roller 1 stored in this in the direction of the

'· Setting 2 is pressing. At its end facing away from the fork 3 is

A pretensioning device 12 is provided in the socket ¹ V, with which the compression spring 5 can be compressed beforehand, in order to preset the spring force exerted by the spring S.

mt

■ ·

This pretensioning device can be formed by a simple screw running in a corresponding thread.

In the bearing plate 6 is firmly connected to this Bearing pin 7 arranged, the axis of which forms the axis of rotation for the vertical spar 9 of the swing gate. This journal extends through the link 2 into the vertical spar 9 and through one arranged in its upper end Bearing bush 8 through and is secured with a transverse pin 10 relative to the vertical spar 9; or. the vertical spar 9 is secured with the transverse pin 10 on the bearing pin 7. The vertical spar 9 is via a weld indicated at 16 firmly connected to the horizontal spar 15.

It has been shown that the mechanism from the gate 2, role 1, etc. is located outside of the spars 9 and 15. However, it is also possible to accommodate this mechanism within the spars. Here, the backdrop with the bearing pin firmly connected below the bearing bushing 8, while the roller-spring mechanism is placed in the bearing spar 15 can be.

Fig. 2 serves in particular to explain the play of forces between the various parts of the reset device according to the invention. Once the role 1 is with i _n

The gate is shown in the closed position. In this case it lies in the recess which inevitably results from the previously described gate shape in the groove corresponding to the gate closing division. Around this zero position, as can be easily seen from FIG. 2, the gate is symmetrical in both opening directions. Since there is a restoring force driving the gate to the closed position in both opening directions, the zero position is stable.

5 ~? ± an opening position of the Tcrss, shown in dashed lines in ύζν 31ä Rolls, the spring force F acts once in the direction of the gate pivot axis A. The reaction force N exerted by the gate can of course only be perpendicular to its surface. As a result, this reaction force N, as can also be easily seen from FIG. 2, is not in the same direction as the spring force F. The resulting restoring force R results from the addition of vectors from the two forces F and N.

In Fig. 2, two depressions 11 are also shown in the link 2, into which the roller 1 can run. Through this Depressions 11, a restoring force is switched off, so that once the gate has been opened this far, it does not close automatically but is triggered from the outside in the closing direction must become. As shown, the depressions 11 are in one

opening angle of about 90 ° attached what a full Door opening corresponds.

The invention thus provides a resetting device for swing gates with a follower element which is resiliently guided on the gate and which is mounted on a swinging gate axis arranged stationary backdrop runs, the curve normal always the closing plane of the gate on the gate facing away from the pivot axis of the door. It can be used for the pressure of the following element on the backdrop Instead of a compression spring, a pneumatic spring can also be used and instead of a roller, e.g.

a sliding block is also used w <? r * «n.
