Description

The invention relates to a control method for Operate a passport control Turnstile system with a fixed system Articulation axis rotatable locking element, which is included preferably the same angle from the articulation axis has extending blocking agents which from their normal operating positions to non-use positions movable and otherwise due to rotation of the Locking element around its articulation axis one after the other one blocking a passage into the latter releasing rotary position can be actuated, wherein each time a blocking agent is advanced from its Locked position in a passage that releases the passage Position the locking device in the direction of rotation in Locked position is moved and when entering the Normal operation disturbing event, such as power failure, at least the blocking means in the blocking position from a position blocking the passage of people in an enabling the uncontrolled passage of people Movable when not in use and this Blocking means after the abolition of the mentioned event resettable to its normal operating position and releasably lockable in this operating position is.

From DE-PS 28 25 787 is a turnstile system for the passage control of people with one inclined at 45 ° to a vertical Turnable turnstile as a locking element known. The turnstile has three trigonal of a storage plate extending locking arms, which at Turn the turnstile one after the other around its bearing axis in an essentially horizontal blocking position or positions releasing the passage of people are movable are. These locking arms are usually under one predetermined angle to the axis of rotation of the bearing plate before, are hinged to the latter but hinged and by means of releasable catches in their normal operating positions held.

Turnstile systems of this type have proven to be a means of Passage control has proven itself, and indeed especially because, for example, at holding the locking arms in their normal operating positions, in which by rotating the Locking element one after the other in a person passage shut off position, by means of electromagnetic locking in the event of a power failure or intended power cut-off in the locked position standing locking arms under the action of gravity Fold-down positions that enable the passage of people swivel. In case of breakdowns thus ensured that in such a way Turnstile facilities secured area in the event of danger Employees are not included, but such an area then as an escape route usable turnstile system essentially unimpeded being able to leave.

However, it is unsatisfactory that after one folds down the event causing the blocking elements, such as for example, power outage, it's a cumbersome one and time-consuming refitting of the turnstile systems required by removing them from their blocking positions beforehand folded down when the disturbing event occurred Lock arms by hand in their normal operating positions must be returned. This is special annoying when, for example, a larger one Company premises using a variety of such Turnstiles are secured.

A very similar turnstile system is also from the DE utility model 69 37 378 previously known, also in the one around one inclined to the vertical Axis of rotation rotatable bearing disc three locking arms are arranged as a result of rotation of the bearing disc successively move into a horizontal locked position and block a passage in this. Also In this turnstile system, the locking arms are after Release the latches holding them in their normal positions foldable with the result that when it occurs of such an event in the locked position locking arm under gravity in a position that clears the passage in question is pivoted.

Even with this known turnstile system, it is unsatisfactory that when the folding of the each effecting blocking arm standing in the blocking position Event, i.e. when the Normal operation, this locking arm manually in its intended Location must be folded back.

Finally, it is also from DE-OS 40 36 878 a turnstile system known, in the radial order of one Guide column arranged with a vertical axis of rotation Locking wings are provided as locking means and for creation at least two of escape routes in the event of danger Locking wing in each case parallel to the turnstile axis of rotation Axes pivotable or out of their locked positions can be folded down. By folding down the blocking wing also becomes an uncontrolled one with this turnstile system Passage of people released.

While with the turnstile systems discussed above with protruding in the blocked position in a pedestrian passage Barrier arms the latter depending on a defined event automatically in a Fold down the passage that clears the passage, required it at the turnstile system discussed last Swiveling the hinged locking wings around their extending parallel to the axis of rotation of the locking element Articulation axles and after the mentioned event ceases to exist have to fold in the folded locking wings manually their intended normal were folded back will. This is cumbersome and time consuming.

The invention is therefore based on the object To create control procedures in which an out its locked position in a non-use position moving blocking means of a turnstile system forcibly and without manual operation in its intended Normal position is reset. It should therefore be a Control procedures are specified, which is an automatic Return of the turnstile system to the operational Normal state enabled.

This problem is solved in that in a turnstile system that in the preamble of claim 1 specified type the locking element with an electrical Advance motor is in drive connection and that after removal of the mobility at least in the locked position standing blocking means in its non-use position triggering event resetting forces that the reset with respect to the articulation axis of the locking element one in a non-use position Cause blocking means in its normal operating position, by advancing the locking means by at least one Progress to act on in the non-use position standing blocking means are brought.

Characteristic of the control method according to the invention is thus that after one is no longer normal operation disruptive event affecting the movement at least the blocking means in the blocking position into a non-use position, onto an in blocking means of its non-use position restoring forces be brought into effect and that this locking device in its normal operating position returned, hence the turnstile system set up to resume normal operations becomes.

For this purpose, the blocking element of the turnstile system is available an electric stepping motor in drive connection, which after the removal of the mobility at least of the blocking means in the blocking position its non-use event triggering event which the resetting of said blocking means in his restoring forces causing normal operating position by advancing the locking means by at least one Progress step to act on the blocking agent brings.

This development of the invention is hence that the resetting one from its normal operating position into a non-use position moving locking means causing restoring forces depending on the advancement of the blocking element restoring action on that in the non-use position standing blocking means are brought.

In a turnstile system with one versus one Horizontal inclined axis of rotation of the locking element and at least approximately horizontal in their locking positions standing as well as upon the occurrence of mobility of the blocking means in a blocking position Non-use event triggering the effect of gravity folding locking arms as locking means can, according to another development of the invention, the provision of a folded blocking device under Effect of gravity occur when the Locking element on the articulation axis of this locking means the blocking element has a lower region of its orbit when turning the locking element about its axis of rotation goes through. Act in this range of rotation of the locking means the weight forces attacking in its focus in the sense of a reset to normal operation corresponding position of the locking means.

The resetting takes place with a particularly high degree of certainty one folded down into a non-use position Locking means in its normal operating position, if in a turnstile system with three approximately trigonal Axis of the locking element arranged the locking arms Reset when advancing the locking element by at least carried out two successive switching steps that is, the one in the folded position Locking arm with its articulation point on the locking element passes through the lower culmination range of its orbit.

Finally sees another very important design the control method according to the invention, that the locking means moved into their non-use positions after the elimination of this mobility Event when advancing the blocking element as a result thereby occurring and acting on these blocking means Centrifugal forces reset to their normal positions will.

While in the further training discussed above the resetting of a locking device from its folded down Non-use position in the normal operating position when circulating the locking element under Gravity has been applied to the further training discussed the restoring forces in the form of centrifugal forces on the folded blocking means upset. These centrifugal forces always take effect Focus of the folded blocking means on and are directed radially to the axis of rotation, but have regular in a perpendicular to the folding axis Components falling in the direction of being resettable and im Meaning of a re-establishment in the normal operating positions Act.

Fig. 5

in an enlarged detail view from FIG. 1, the mounting of a locking arm which can be folded down from the normal position shown on a turntable, which in turn can be rotated about the inclined axis of rotation and can be driven by a motor.

In the turnstile system shown in the drawing 10 is a drive unit on a stand column 11 12 added with a turnstile 13, the three each offset by 120 ° Has locking arms 14 and one against one - imaginary - horizontal axis inclined by about 45 ° 15 rotatably mounted on the drive unit 12 is. The locking arms are in turn at right angles to Axis of rotation of the turnstile their normal positions shown in particular in FIG. 1 can be folded down on one when not in use Storage plate 16 hinged, which in turn with a in the drive unit 12 received - not shown - Advance motor is in direct drive connection and therefore when advancing about the said axis of rotation 15 is rotatable. The locking arms 14 extend trigonal away from the storage plate 16, on the Mantle of an imagined look after that from the storage plate pioneering side opening cone jacket lying.

One of the three locking arms is in normal operation 14 in a horizontal, in a passage protruding locking position while the rest two locking arms 14 from the passage in obliquely after layers pointing below are pivoted, as is the case in particular 1 and 3 show. If a person the Turnstile system 10 enters the locked position standing locking arm as a result of being triggered by this person by means of the indexing motor by rotating the bearing plate 16 and thus the turnstile 13 from his Locked position moves and therefore the passage of people Approved. At the same time it moves in the direction of rotation following locking arm 14 in a the passage behind blocking position for a person passing through the latter.

In the turnstile system 10 shown, each with Barrier arms 14 offset from each other by 120 ° corresponds to a rotational cycle of the turnstile 13 one Rotation of 120 ° and there is a locking arm in each Normal operation in a blocking the passage of people Blocking position. Here are, as below in individual is explained, the 16 on the storage plate a pivot axis lock arms 14 in the in particular normal operating positions shown in FIG. 1 releasably locked and in these locking positions held by electromagnets what's below is explained in more detail in connection with FIG. 5. If now due to power cut or power failure electromagnetic mounting of the locking arms in the mentioned treachery ceases to apply, it works in its essentially horizontal locking position standing locking arm 14 under the action of gravity this locked position, that of the normal operating position corresponds to the assigned passage releasing non-use position, such as this shows Fig. 3. Given the presentation of the Turnstile 13 the other two locking arms the passage also release is after folding the locking arm originally in the locked position an uncontrolled passage of people is possible.

After the folding of the in the locked position standing blocking arm triggering event the turnstile system is reinstalled according to the invention 10 in their normal operating state that the stepping motor the turnstile 13 in so advanced by rotation about the axis of rotation 15, that the folded down when not in use Locking arm 14 when advancing under the action of gravity about its pivot axis on the bearing plate 16 in swings back its normal operating position and locked there. This pivoting back of a folded Locking arm in its normal operating position is achieved in a particularly secure manner if with a turnstile with three at 120 ° to each other staggered locking arms after elimination of the event triggering the folding of a blocking arm the turnstile by at least two steps is advanced so that the articulation axis the from its non-use position to the normal use position locking arm 14 to be reset on the bearing plate 16 the lower culmination point of their orbit goes through.

In Fig. 5 is the omission of the other locking arms from the operating position shown to a non-use position hinged linkage of a locking arm 14 illustrates on the bearing plate 16 of the drive unit 12. This articulation serves at right angles bearing journal extending to the axis of rotation 15 of the turnstile 13 20. These journals are no further in here interestingly added to the bearing plate 16, which in turn rotatably on one with the drive shaft of the indexing motor are in drive connection Block body 21 is attached. On this journal is one at the end of the respective locking arm 14 arranged bearing tongue 22 pivotally received. On the side facing away from the actual locking arm from Bearing journal 20 has a respective bearing tongue Bolt shoulder 23 by a bolt nose 24 one Rotary bolt 25 is engaged. This rotary latch is parallel to the respective articulation axis of the relevant locking arm arranged on the bearing plate 16 Bearing pin 26 in a recess of the rotation with the bearing plate 16 connected block body 21 pivoted, against the effect a return spring 27.

At its end facing away from the respective bearing pin the assigned rotary latch 25 has a radial after externally directed nose 28 by one on the axis of rotation directed projection 29 of a slider 30 underneath is. This slider is powered by an electromagnet 31 in its position shown in FIG. 5 held.

In the event of an event that leads to a malfunction the current applied to the electromagnet 31st interrupted with the result that one of the above Slide 30 attacking return spring 32 the slide from the stop position shown in FIG. 5 and thereby the rotary latch 25 around that of the bearing pin 26 articulation axis formed on the block body 21 panned. As a result, the locking lug 24 of the Turn bolt out of engagement with the bolt shoulder 23 the bearing tongue 22 and then the locking arm pivots 14 under the effect of its own weight its horizontal blocking position in a vertical position.

The two locking arms, not illustrated in FIG. 5 are identical to the locking arm shown stored and in their normal operating positions held or unlocked from these.
