Abstract

In the case of a lock for people which is constructed in the manner of conventional turnstile lock arrangements and has a delimiting means, in the form of a segment of an arc of a circle, on one side of a through-passage and a blocking element which can rotate about a vertical spindle arranged in the centre of said delimiting means, a shutter-door element, instead of a fixedly installed blocking screen, passes as far as the revolving-door spindle, which shutter-door element can be pivoted between an open position, which releases a through-passageway beside the revolving door, and a closed position, which blocks off said through-passageway. <IMAGE>

Description

The invention relates to a security gate with a circular segment-shaped boundary on one side of a passage, the open side of which points to the other side of the passage and which extends over a predetermined circumferential angle, with a locking element rotatably mounted about a vertical axis arranged approximately in the center of this boundary, which is provided with inclines which preferably extend at the same angle from one another from the axis of rotation from spaced-apart grating bars, and with a locking rake which extends from the axis of the blocking element to the other side of the passage and is arranged at a distance from one another and offset from the grating bars of the wings, the unrestricted rotatability of the locking element allowing bars.

In a known security gate, which is described in a company brochure of the applicant, the locking element rotatable about a vertical axis consists of a turnstile with three wings each offset by a circumferential angle of about 120 ° and the Circular arc segment-shaped boundary arranged on one side of the passage extends over a circumferential angle of approximately 120 °. The arrangement is such that when the locking element is symmetrical to the boundary, there are at most gaps of a size between the ends of the boundary and the ends of the locking element wings that do not allow people to pass through. The barrier on the other side of the passageway receiving the security gate, on the other hand, is a so-called comb rake, which also consists of spaced-apart lattice bars which are offset relative to the lattice bars of the wings of the locking element designed as a turnstile so that during rotation of the locking element about its vertical axis, the bars of the wing can pass freely between adjacent bars of the barrier.

This known security gate can be equipped with a simple return lock or with an electromechanical lock for the turnstile and can therefore be walked on in one direction or in two directions. In this respect, this security gate can be used equally as an entrance or exit gate, but also as a combined entrance and exit gate.

Such security gates are often used for the external security of company premises and are integrated in fences, walls or other enclosures surrounding the latter. What is unsatisfactory with the previously known security gate is that it does not allow the transport of larger loads and also the requirements for Escape routes are not sufficient in the event of danger. Rather, additional passageways must be provided for the transport of goods and escape routes, for example in the form of gates, which are arranged next to the personnel locks in the enclosures and can be opened if necessary. On the one hand this is costly and on the other hand it is problematic in the event of danger in that the escape routes are then different from the usual passages.

In contrast, the invention is intended to provide a security gate which is simple in construction and which, if necessary, can be quickly and easily converted to a large passage which allows the transportation of loads or which can be used as an escape route, but in which an unwanted passage cannot occur in any turnstile position.

This object is achieved in that in the security gate according to the preamble of claim 1 the locking rake is designed as a movable gate element between a closed position and a position releasing a passage and that the locking element is a revolving door with at least two leaves.

In contrast to the prior art, in the security gate according to the invention, simply by actuating the gate element - which can be locked in its closed position - into its open position with simultaneous rotary adjustment of the revolving door so that its wings each cover the arcuate segment-shaped side boundary, a large passage in the area of the Passage receiving passage can be produced. This passage is as a load transport route and / or Escape route usable. For use as an escape route, it is particularly important that it practically coincides with the usual access routes.

According to a development of the invention, the gate element can be pivotable about a vertical axis between its closed position and its open position. As far as the circumstances allow, the gate element can also be designed to be displaceable in its longitudinal direction within the scope of the invention and can accordingly be brought into its open position by displacement.

Another useful development provides that the circular segment-shaped boundary extends over a circumferential angle of at most 180 ° and that the wings of the revolving door extend away from the revolving door axis on opposite sides.

Such lock formation is extremely simple and inexpensive in construction, but is also characterized in that it only requires the setting of the revolving door in a position covering the circular segment-shaped side boundary and the pivoting of the gate element into its open position in order to produce a large passage.

In yet another advantageous development, the revolving door is designed as a turnstile with at least three wings and at least one wing can be pivoted about an articulation axis parallel to the revolving door axis in the direction of an adjacent wing.

In this development, as with a double-leaf revolving door, when the door element is pivoted in the open position, the entire passage between the Revolving door axis and the other side of the passage released when the revolving door is in a rotary position in which two adjacent wings cover the arc segment-shaped boundary and the other wing is pivoted into a position, for example, perpendicular to the closed position of the gate element.

Naturally, instead of a three-wing turnstile, a four-wing turnstile can also be used in conjunction with a circular segment segment-shaped boundary extending over a circumferential angle of up to 180 °. With such a circumferential extension of the lateral boundary, a turnstile adjustment is achieved in such a way that only one wing protrudes into the passageway, which then has to be pivotable in the same way as in the three-wing design for the optional release of a wide passageway into a position approximately perpendicular to the closed position of the gate element .

It is characteristic of the personal lock according to the invention that, when the gate element is in the closed position, the lock can basically only be passed through the actual lock space, that is to say along the path specified by the circular segment-shaped boundary with simultaneous rotation of the revolving door. There can therefore be no uncontrolled opening in the lock area in any pivot position of the revolving door.

In the context of another expedient development, the gate element is articulated on or in the region of the revolving door axis and can therefore be pivoted about this articulation axis with the opening of a wide passage into an opening position perpendicular to its closed position.

Analogously, the gate element can also be pivoted on the side of the passage that is remote from the revolving door by means of a hinge axis parallel to the revolving door axis.

A further development provides that on both sides of the passage a circular segment-shaped boundary is arranged with a revolving door and that between the revolving doors the latter one reaching up to the revolving door axes as well as or respectively. extends in the region of a pivot door axis pivoted gate element.

This further development is thus a double lock system, in which a gate element consisting of two gate leaves can also be used instead of a gate element, the gate leaves being pivotably articulated on or in the region of a revolving door axis between a closed position and an open position, and each gate wing with its end remote from its articulation axis extends to the corresponding end of the other gate wing and the two gate wings can be locked at least in their closed positions.

It has also proven to be expedient in this development if the door leaves have U-shaped frame parts, the legs of which are connected to one another by a web and are pivotally mounted with their free ends at the lower and upper ends of the associated pivot door axis or in the region thereof, and when the bars of the frame parts, which run approximately parallel to the revolving door axes and extend at a distance from one another and extend close to the respective revolving door axis.

A security gate is already known from EP-A-0 364 648, which can be converted from a normal lock route to a widened passage way, but it is not a lock with a turnstile or turnstile system, but rather a so-called pendulum lock, which is intended in particular to control and secure the entrance areas of buildings.

This lock has a semi-cylindrical wall as a boundary on one side and a semi-cylindrical jacket serves as a blocking element, which is rotatably mounted in the center of the semi-circular wall and supplements the semi-cylindrical wall into a cylinder in one of its rotational positions. Between this locking element, which is designed as a half cylinder, and the other wall delimiting the passage, a swing door hinged to the latter is arranged, which can be pivoted between a closing position reaching up to the rotating element forming the rotating locking element, and an opening position perpendicular thereto.

In the known pendulum lock, the locking element designed as a semi-cylindrical jacket can be rotated in four positions, with the lock closed on both sides in a first position, open in two further positions on each side and open in a fourth position on both sides. In the latter position, although a widespread passage is realized, it appears unsatisfactory that it allows precise control of the rotary movement of the locking element and, above all, the locking needs in one or the other end position, because otherwise an undesired turning of the locking element into the fourth operating position can take place, in which an unwanted and, above all, uncontrolled passage path can occur independently of the actual lock path.

With regard to the invention, in which an uncontrolled opening in the lock area is not possible in any position of the revolving door, the lock known from EP-A 0 364 648 was unable to provide any suggestion, because the pressure positions of the locking element which enable unsecured access when the lock is open Technology can only be prevented by a considerable control engineering effort, while such a backup occurs automatically in the invention.

.In the lock 10 illustrated in FIGS. 1 to 5, on one side there is a side post 11, 11 which is only indicated between

formed passage of a barrier that is not of interest here, immediately adjacent to the one post 11, a circular segment-shaped boundary 12 is arranged, which consists essentially of vertically extending bars. This boundary extends over a circumferential angle of approximately 180 ° and points with its open side to the post 11 delimiting the passage on the other side

Die Flügel dieser Drehtür erstrecken sich auf einander gegenüberliegenden Seiten von der Achse 15 fort und bestehen aus beabstandet übereinander angeordneten Gitterstäben.The lock also comprises, as a rotatable locking element, a revolving door 13 with two wings 14, 14

which is rotatably mounted about a vertical axis 15 arranged in the center of the circular arc-shaped boundary. The wings of this revolving door extend on opposite sides from the axis 15 and consist of spaced lattice bars.

und der Drehtür-Achse 15 erstreckt. Dieses Torelement ist auf der von der kreisbogensegmentförmigen Begrenzung 12 entfernten Seite um eine dem dortigen Pfosten unmittelbar benachbarte vertikale Achse 17 Zwischen der aus den Figuren 1 bis 3 ersichtlichen Schließlage und einer Öffnunglage verschwenkbar angelenkt, wie die Fig. 4 und 5 zeigen. Das Torelement 16 besteht im wesentlichen aus beabstandet übereinander angeordneten Gitterstäben, die sich von der Anlenkachse 17 forterstrecken und in der Schließlage des Torelements bis an die Drehtür-Achse 15 heranreichen, aber gegenüber den die Drehtürflügel bildenden Gitterstäben derart höhenversetzt sind, daß beim Verschwenken der Drehtür 13 die Gitterstäbe der Türflügel 14, 14

durch die Zwischenräume zwischen den Gitterstäben des Torelements 16 ungehindert hindurchtreten können.Finally, the lock includes a gate element 16 which is designed in the manner of a rake and which is located between the post 11 which is removed from the boundary 12 in the form of an arc segment

and the revolving door axis 15 extends. This gate element is articulated on the side remote from the circular segment-shaped boundary 12 about a vertical axis 17 directly adjacent to the post there between the closed position shown in FIGS. 1 to 3 and an opening position, as shown in FIGS. 4 and 5. The gate element 16 consists essentially of spaced lattice bars which extend from the articulation axis 17 and reach in the closed position of the gate element up to the revolving door axis 15, but are offset in height relative to the lattice bars forming the revolving door leaf in such a way that when the revolving door is pivoted 13 the bars of the door leaves 14, 14

can pass freely through the spaces between the bars of the gate element 16.

Apart from the articulation of the gate element 16, which can be pivoted about a vertical axis, on the side of the passage receiving the lock 10 which is remote from the revolving door 13, the lock illustrated in FIGS. 1 to 5 is constructed in the manner of known turnstile systems.

In the operating position illustrated in FIGS. 1 and 2, the gate element 16, which is articulated on one side of the passage receiving the lock 10, and the gate element 16 which is rotatably mounted about a vertical axis 15 in the center of the circular segment-shaped boundary 12 Revolving door 13 in alignment with each other. The lock is therefore closed. If, in the direction of the arrows indicated in FIG. 2, a person wants to pass the lock, after the revolving door has been released, it can be rotated clockwise or counterclockwise about its vertical axis, depending on the direction of passage of the person passing through.

3 shows a rotary position of the revolving door, in which a person passing through the lock can be in the lock area. The passage area lying next to the lock is blocked 16 in this operating position by the gate element which is in the closed position and which extends almost to the axis of rotation 15 of the revolving door 13 and is designed in the manner of a lock rake.

FIGS. 4 and 5, on the other hand, illustrate an operating position in which the revolving door 13 is in the same position as in FIG. 3, while the gate element 16 articulated on the other side of the passage is pivoted into an opening position parallel to this revolving position of the revolving door. This operating position enables an uncontrolled passage and, in addition to the function, for example as an escape route, also loads can be transported.

In the embodiment illustrated in FIGS. 6 and 7, the same parts as in FIGS. 1 to 5 are provided with reference numerals increased by ten each.
