• different activation states can be assigned to the light barriers.
• An activation state is a transition activation state, which is assigned to a control circuit of at least one of the leading gate edge closest, but not yet detecting photocell, such that this at least one light barrier in the subsequent detection of the leading gate edge does not emit the security circuit triggering signal.
• Another activation state is a passive state, the control circuit of each one previously in

• the photoelectric sensors in the passive state do not generate a safety signal that stops the closing movement of the door.
• Object and advantages of the invention is to provide a device of the type described in the introduction for securing a driven movement element against unwanted collisions, which results in an improved safety situation with respect to a movement path of the moving element compared to the prior art.
• This object is solved by the features of claim 1, 7 and 9, respectively.
• the invention relates to a device for securing a driven movement element against unwanted collisions with lying on a predetermined path in the direction of movement of the moving element Obj ect, which comprises a photoelectric barrier arrangement with a plurality of in the direction of movement of the moving element successively arranged light barriers and an electronic unit with which the movement of the movement element as a function of a detected object in a safety mode can be stopped and / or reversed.
• the electronic unit is designed to assign the light barriers different operating states, of which a first operating state is an active state in which the respective object detecting light barrier generates a signal which triggers the safety mode and a second operating state is provided.
• the second operating state is a measuring state in which the respective object detecting light barrier generates a measuring signal which does not trigger the safety mode
• the electronic unit is designed on the basis of a Time difference, which requires the movement element from a first photocell to a lying in the direction of movement of the moving element second light barrier, the time difference on the first and second photocells is determined, and a distance between the first and second photocells a third photocell preferably from the active state to the measurement state to transfer when the moving element is on the way between the second and third photocell and even before the moving element reaches the third light barrier.
• the monitored area can be approximated relatively close to the zoomed motion element. Because the third light barrier can be switched from the active to the measuring state shortly before the arrival of the moving element with appropriate time calculation.
• the electronic unit determines, for example from the time difference from the first to the second light barrier by triggering these light barriers, a time at which the third light barrier would be detected and switches the third light barrier in the measuring state in good time before this event occurs.

• the electronic unit assigns the electronic unit two light barriers, which triggers the movement element in a movement in the direction of movement in the light barrier arrangement as the first, the measurement state. If the movement element is located outside the light barrier arrangement before movement, these two light barriers are preferably the first two light barriers of a measuring field of the light barrier arrangement. However, it is also conceivable that the movement element is already in the measuring field of the light barrier arrangement. Then, preferably the two light barriers are assigned the measuring state to which the moving element first encounters a movement in the direction of movement.
• the electronic unit adds a measurement signal of at least one third light barrier to the measurement signals of the first and second light barriers for the calculation of the movement of the movement element.

• the movement of the moving element in the direction of movement can be comparatively predict exactly.
• the switching of operating states of the light barriers can be reduced to a minimum, resulting in a comparatively small gap between the monitored area and the moving element.
• the light barrier arrangement comprises an indicator which indicates which light barrier is in the active state.
• Another essential aspect of the invention resides in a design of the electronics unit such that light barriers which lie in the direction of movement on the path of the movement element are initially held in a passive state and only transferred from the passive state to an active state when the movement element moves in the direction of movement reaches the photocell in a given time.

• z. B. the movement of two mutually moving gate elements are hedged.
• two light barriers in measuring mode are preferably each on opposite sides, which are first detected by the respective gate, ie the moving element during a movement in the direction of movement. All other procedures then correspond to what has been described above, with the exception that the safety mode then stops the movement of both gate elements as soon as an object is detected in the movement area.
• the electronic unit is designed so that the light barriers are successively transferred to an active state when moving back a moving element. For this it is necessary that the light barriers are in 'a state of measurement. However, it is also conceivable to bring the light barriers into an active state only when the movement element is outside the monitored area.

• the uppermost two light barriers 7-1, 7-2 are in a measuring state.
• a measurement signal is output to the control circuit 13 (FIGS. 5-11 and 5-III) when the light barriers detect an obj ect in the form of the door 1.
• this movement is preferably only interpreted as a door movement when the light barrier signal is emitted within a predetermined time corridor.
• All remaining light barriers 7-x are in the active state, according to the specification of the control circuit 13. Based on the measurement signals of the two located in the measuring state light barriers, the control circuit 13 determines the time in which the light barrier 7-3 would detect the door 1 and switches them in time to the measuring state (see Figure 5-IV). If the door 1 continues to move, then a measurement signal is generated by the light barrier 7-3, which is in the measuring state (see FIG. 5-V), which is used to determine the time at which the light barrier 7-4 of FIG Gate 1 is blocked. This calculation can be based on the last two measurement signals, or on several previous measurement signals. In the latter case, in addition to the speed and the acceleration of the gate can be determined, making a more accurate prediction of the position of the gate 1 is possible. Before the light barrier 7-4 is detected by the gate 1, this is also transferred to the measuring state. This provides another measurement signal when the gate 1 passes the light barrier 7-4.
• a light barrier 7-23, 7-24 is connected in order to be able to monitor the respective area immediately in front of the front edge 4 of the door 1 for obstacles (see FIGS. 7 and 8). If an obstacle 15 z. B. detected by the photocell 7-24 (see Figure 8), a signal activating the safety circuit 10 is generated and the gate stopped and opened.

• FIGS. 9-1 to III a gate closing from two sides is shown, as is shown in FIG. B. used in goods lifts.
• This gate consists of two parts Ic, Id, which in opposite directions in z. B. move in the vertical direction. So that neither of the two parts Ic, Id are identified as an obstacle 15, the measuring state must be assigned in good time to the two light barriers 7-lc, 7-2c or 7-ld, 7-2d. This can happen in two ways:
• the light barriers 7-xc determine the speed of the upper half of the door Ic and the measuring state is assigned to the light barriers 7-xc and 7-xd at the same time on the basis of these signals.
• a second possibility is that the light barriers 7-xc determine the speed of the door half Ic and that the measuring state of the light barriers 7-xc is assigned on the basis of this speed.
• the light barriers 7-xd autonomously determine the speed of the door half Id and the measuring state is assigned to the respective light barriers 7-xd on the basis of their measuring signals.
