Abstract

The swing gate arrangement has a contactless people-scanning device (7) which is arranged in front of the swing gate and at least one further contactless people scanning device (19) which is provided at the gate (15). The devices control a gate- swinging electric motor. This ensures that a gate approaching a person remains at a distance from this person for an unlimited time. The person is not hit by the gate. <IMAGE>

Description

SPECIFICATION Swing gate arrangement for gateway installations for people The invention relates to a swing gate arrangement for gateway installations for people, consisting of a column comprising a gate leaf arranged thereon and a people scanning device which acts in contactless manner and by means of which the gate leaf is caused to swivel by means of a motor-powered drive unit.
Swing gate arrangements of this type are known, for example, through European Patent Application 0,075,806 and through the German Registered Design 7,703,290. In both swing gate arrangements, the gate leaf opens the gateway for people when a person or an object at least partially interrupts the directional beam of a microwave or ultrasonic transmitting/receiving device emanating from the people scanning device. In this arrangement, the gate leaf remains for a fixed duration of time in the open position and then automatically closes the gateway again. This has been found to be disadvantageous in the past. Due to the fact that the time the gate leaf is open is exactly fixed, it can naturally never adopt itself exactly to the very different types of behaviour of the people passing through the gateway.In particular, smaller children with their lack of concern do not yet know that the gate leaf moves automatically.
Thus, it happens time and again that children who suddenly stop within the swivelling range of the gate leaf whilst passing through are hit by the metallic gate leaf returning to its starting position.
Thus, the invention has the object of eliminating the abovementioned disadvantage in a swing gate arrangement of the type initially mentioned. The sequence of movement of the gate leaf is to be controlled in such a manner that it always takes into consideration a person located within the gateway, regardless of how this person is moving.
According to the invention, the object is achieved by the fact that at least one further people scanning device, which is effectively connected to the drive unit and operates in contactless manner, is arranged at the gate leaf and that, in addition, this people scanning device electrically overrides the people scanning device located outside the gate leaf for as long as the directional beam of the people scanning device arranged at the gate leaf is at least partially interrupted by a person or an object.
This measure reveals that the sequence of movement of the gate leaf, which is fixed in time, is rendered ineffective when a person is located within the range of the directional beam of the people scanning device arranged at the gate leaf. Thus, the gate leaf does not automatically return to its starting position after a certain time but remains at a distance from the person standing within the gateway area. Thus, this person is not hit by the gate leaf if he or she stops. This is of a quite decisive advantage, keeping in mind, as mentioned, children who do not always pass smartly through the gateway. Similarly, the previous known possibility is eliminated that a person who has alrady passed through the gateway for a distance and the gate leaf has returned to its starting position, is hit from behind by just this gate leaf when another person is passing through the light barrier.
The gate leaf opens only far enough for the directional beam of the people scanning device arranged at the gate leaf to impinge on the first-mentioned person. From this time onwards, the gate leaf again remains at a distance from this person.
The invention will be explained in greater detail with the aid of two preferred illustrative embodiments, in which Figure 1 shows a complete swing gate arrangement; Figure 2 shows a variant of Fig. 1, and Figure 3 shows a simplified circuit diagram for the embodiment of Fig. 1.
The swing gate arrangement 1 shown in Fig. 1 consists of a contactless people scanning device 2 and a swing gate 11, a gateway 10 for people being formed in the example by two guide struts 3 each which extend on the left in the picture from the people scanning device 2 to the swing gate 11 and on the right in the picture extend from the people scanning device 2 to a post 4 standing close to the gate leaf 15. The people scanning device 2 consists of two posts 5, 6 which are arranged at a distance from each other, a light source 8 being arranged in the post 5 and a reflector 9 being arranged in the post 6 so that a so-called "light barrier" 7 is formed.
Such light barriers 7 are adequately known so that their more detailed description can be omitted. The people scanning device 2 is effectively connected to the swing gate 11 in such a manner that the gate leaf 15 opens the gateway 10 when a person steps through the light barrier 7. This principle, too, needs no further explanation since it is already known. In the example, the swing gate 11 is designed in accordance with the features disclosed, for example in European Patent Specification 0,075,806. Thus, the swing gate 11 is provided with a round column 12 in which the movable gate leaf 15 is arranged between an upper and a lower column section 13, 14.
In the example, the gate leaf 15 is provided with a pipe section 16 which is arranged on the same vertical axis as the column sections 13, 14 and which carries a horizontally arranged swing part 17 which transversely spans the gateway 10 in the starting position.
The swing part 17 is usually fabricated from a pipe of U-shaped design, both legs of the pipe being joined to the pipe section. The swing gate 11 can also consist in known manner of a column (12) having a rectangular or square cross-section, the swing part 17 being mounted on arms projecting out of the column (12). In the column sections 13, 14 and in the pipe section 16, a drive unit 18 is provided which moves the gate leaf 15 and which essentially consists of an electric motor and a gear train. The drive unit 18 arranged in the column 12 is electrically connected to the people scanning device 2. At the pipe section 16 of the gate leaf 15, another people scanning device 19 is arranged the effective range 20 of which extends along the swing part 17.
The people scanning device 19, constructed as transmitting and receiving unit, can operate either with ultrasonic or with light cones or also build up high-frequency fields. Whatever is used in the final analysis determined by the individual case but it is recommended to may choose ultrasonics since the range of this can be accurately set. The effective range 20 of the people scanning device 19 is shown in dashes in the drawing.
If then a person steps through the gateway 10 in the direction of the arrow, the gate leaf 11 is caused to open the gateway 10 when the light beam of the light barrier 7 is interrupted. In the drawing, the gate leaf 15 swivels to the left. The gate leaf 15 remains for a short time in the open position and then automatically closes again if the person has passed through the gateway 10 within this time. However, if this person takes longer to pass through or if he or she even stops, the gate leaf 15 returns in the direction of its starting position only until the effective range 20 of the people scanning device 19 has detected the person. From this time onwards, the gate leaf 15 stops. If the person goes back, the gate leaf also swivels further back and if he or she goes forward, the gate leaf 15 opens.
To extend the effective range 20 of the people scanning device 19, it is possible in accordance with Figure 2 to attach one people scanning device 19 each to the pipe section 16 on both sides of the swing part 17. The effective ranges 20 of both people scanning devices 19 extend along the swing part 17.
Otherwise, the construction of the swing gate arrangement 1 is the same as the one described in Fig. 1.
Fig. 3 shows in a greatly simplified circuit diagram how the individual assemblies of the swing gate arrangement 1 are electrically connected to each other. Starting from the mains system, the current flows via the mains connection to the distributor. The distributor is connected to the electric motor which moves the gate leaf 15 via the drive unit 18. An electronic control unit is connected via the distributor to the electric motor, the people scanning device 19 located at the gate leaf 15 being connected to the control unit. In the circuit, the electronic control unit is located in such a manner that it is arranged between the light barrier 7 provided as people scanning device 2 and the distributor or the electric motor.The control unit is programmed or connected in such a manner that the signals emanating from the light barrier 7 are overriden by pulses flowing from the people scanning device 19 into the control unit. This ensures that the movement of the gate leaf 15 is controlled by the people scanning device 19 when a person is located within its effective range 20 even if the light barrier 7 is simultaneously influenced by another person. An exact description of the circuit of the control unit is omitted since the specialist is skilled in producing different circuits meeting the requirements of the task. In commerce itself, the people scanning devices 19 are known, for example, by the terms "ultrasonic proximity switch" or also "reflective light scanner".
It also remains to be noted that the swing gate arrangement 1 according to the invention can also be provided with two swing gates 11 which are arranged in mirror image of each other and the gate leaves 15 of which point towards each other. In this type of construction, a people scanning device 2 also precedes the arrangement and at least one further people scanning device 19 is also located at each gate leaf 5. It is also possible to equip a swing gate arrangement of the type of the German Registered Design 7,703,290 with a people scanning device 19.
Finally, it should be mentioned that, instead of the column 12, naturally any other fixed point familiar to a specialist and appropriately constructionally designed for carrying the gate leaf is available. In the two illustrative embodiments of Fig. 1 and 2, the column 12 has only been selected as support unit because such upright columns 12 are used in almost all known swing gate arrangements.
