EP1775409A2 - Building or yard closing device with surveillance of the pivoting zone of the pivoting wings - Google Patents

Abstract

The closure which can be a window, door or gate has one or more sensors to detect the position and speed of objects in the vicinity. The closure can be driven by a motor which responds to signals from a signal evaluating unit. The distance from an obstruction, the absolute speed and/or the relative speed to the object can be determined through the sensor and associated signal evaluation unit. Signals and sensor allow an end position to be reached through stored comparison values.

Description

The invention relates to a building or Hofabschlussvorrichtung, such as a gate, a door or a window.

There is an effort to automate building and yard closure devices such as gates, doors or windows, i. H. automatically open or close. However, in the case of automatic opening and closing, there is a problem that a person or an object may be located in the movement area of the building and yard closure device or that a person or an object may move through the opening and closing area of the building and yard completion device. In the case of persons there is a risk of injury to the persons, while the corresponding passing through of objects or positioning of objects in the range of movement of the building and Hofabschlussvorrichtung there is a risk of damage or destruction.

To prevent this, it is known, for example in sectional doors or roller shutters, to provide the end edge with a sensor that is in contact with a detected in the range of movement of the door object and brings the door closing mechanism to a standstill. However, such a system can not be implemented, for example, in the case of a pivoting window or a swinging door in this form.

Object of the present invention is therefore to develop a building and Hofabschlussvorrichtung, such as a gate, a door or a window, such that this safely prevented with appropriate automation that a collision with a standing in the movement area or through it Person or object is prevented safely.

According to the invention, this object is achieved in that the building and Hofabschlussvorrichtung has at least one sensor that detects the location and speed of objects in the vicinity of the range of motion. About this sensor the danger area is now observed around the building and Hofabschlussvorrichtung around. The danger area is that area which is swept over by automatic movement of the building and yard completion device. This monitoring is intended to provide dynamic detection and assessment of potential obstacles. For this purpose, the information of distance or distance, d. H. the location of the object or person, the absolute speed of the building and yard closure device and / or the relative speed to the obstacle.

Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim. Accordingly, the building and Hofabschlussvorrichtung can be driven by a drive motor which can be controlled via a signal evaluation unit according to the recorded signals. This means that the signals corresponding to the location and the speed of the object or person in the monitored area are evaluated and that these signals are transmitted to the drive motor to stop it, or the buildings - or Hofabschlussvorrichtung To slow down the transmitted closing or opening speed or accelerate if necessary, to safely prevent a collision.

Thus, according to the invention, the distance to an obstacle, the absolute speed and / or the relative speed to the obstacle are determined via the sensor and the associated signal evaluation unit.

Signals can also be received via the sensor to reach the end positions. The respectively currently recorded signals for reaching the end position can be compared with stored comparison values.

As a result, a self-learning and self-optimizing system can be created.

As sensors optionally sensors of radar technology, laser technology, infrared technology, ultrasound technology and / or video technology in question. When using the laser technology, for example, the laser Doppler method can be used. Basically, all sensors are suitable, the location, d. H. can capture the location of the object and the speed of the object.

According to a particularly advantageous embodiment, the sensor is arranged on the moving device itself. In addition, if required, at least one sensor can be arranged stationarily outside the moving device.

Further features, details and advantages of the invention will become apparent from the illustrated with reference to the drawings embodiments. Show it:

In Fig. 1 by way of example a garden gate 10 is shown, which is hinged on one side about two hinges 12 pivotally mounted on a post 14. This garden gate 10 thus performs a rotary wing movement from a closed position, as shown in Fig. 2 by the solid lines, in an open position, as shown in Fig. 2 by dashed lines. During opening or closing, the garden gate 10 passes over the hatched area 16 in FIG.

At the outer edge 18 of the garden gate, a sensor 20, for example, a radar sensor 20 is arranged. With this radar sensor 20, the location and the speed of an object or a person located in the hatched area 16 are detected. This can be an object resting in the shaded area or a stationary person or an object moving dynamically through this area or a person passing through this area. The sensor 20 detects the position and speed of the position change or the person and reports these signals to a signal evaluation unit, which is not shown in detail in FIG. 1 or FIG. 2. The corresponding signal evaluation unit outputs the corresponding signals to a drive motor likewise not shown in the illustrations according to FIG. 1 or FIG. 2 and controls them correspondingly in order to either slow down or accelerate the movement of the garden gate 10 in such a way Collision with the located in the area 16 object is reliably prevented. If necessary, the garden gate can also be completely stopped to avoid a collision.

FIGS. 3 and 4 show a garage door 100 in the form of a sectional door 110, at the lower edge of which a first sensor 112 is placed. By way of example, this is an ultrasonic sensor that monitors the space below the closing gate. This is indicated by the beam paths B. A further ultrasonic sensor 114 is arranged in the area of the door border, which continuously detects the distance to the closing gate and can dynamically compare the closing of the gate with stored past values. In this respect, a self-learning and self-optimizing locking system can be realized. As already shown with reference to the garden gate 10 in the exemplary embodiment of FIGS. 1 and 2, the sectional door 110 is also slowed or stopped when a corresponding object or a person is in the monitored area or moves through it.

In the embodiment according to FIG. 5, a sliding door 210 is shown, on which also a sensor 212 monitors the location and speed of an object located in the monitored closing area of the sliding gate 210 or a person located there. Here, not only the area when closing the gate, but also when opening the gate in the immediate movement area of the gate is monitored (area A or B).
