BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to an indicating means for a door operator device for indicating the fully open and/or fully closed position and/or for indicating movement of the door between those opened or closed positions. The door must be a roller shutter door or a tilt door or a sliding door or other door or gate.
BACKGROUND OF THE INVENTION
Hitherto in the art of automatic operator devices for garage doors it has been common to provide a push button means at a remote location such as in the kitchen of a house or in an office adjacent a factory, whereby the garage door can be operated simply by depressing the button. It is a problem to know if the door is fully opened and/or fully closed as it is often not possible to physically view the door from the remote location.
The problem is even more acute now, as in recent times there has been provided a circuit means within the electric driving means which opens and/or closes the door, to reverse the movement of the door during closing if the door should strike an object. This feature is provided to prevent (A) damage to objects which may be under the door and (B) to prevent damage to the door. Thus, in the prior art constructions, when the switch is operated at the remote location, and the door moved from the opened position to the closed position, if it engages with an object under the door it then moves to the fully opened position again. The operator is then not aware that the door is open unless it is physically inspected.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been devised to provide a means to indicate when the door is fully opened and/or fully closed. A particularly preferred embodiment incorporates a feature which indicates that the door is moving towards the closed position and/or the opened position and then provides a further indication when the door has reached the respective fully opened and/or fully closed position.
Therefore in accordance with the present invention there may be provided an indicating means for a door operator device, said indicating means being for indicating either or both of a door fully opened and/or fully closed condition, said door operator device having drive means for moving the door to said positions in response to operation of initiating means, said operator device having circuit switch means to switch off the drive when the door has reached either of said positions, and wherein said indicating means is operatively interconnectable with said door operator device arranged to provide said indication when the door is in the respective fully opened or closed condition.
It is particularly preferred that said indicating means be operatively connected with said circuit switch means to provide an indication that the door has reached either of said positions in response to said electric circuit switch means operating to switch off the drive.
Most preferably, the indicating means is provided at a remote location and takes the form of an indicating lamp means for each of the respective opened and/or closed positions. It is particularly preferred that the lamp means be hard wired with respect to the electric circuit switch means, but it is feasible to use a radio control link between the electric circuit switch means and the indicating means and this is to be considered within the scope of the invention.
It is also particularly preferred to provide the indicating means in the form of one or more flashing L.E.D. lamps to indicate that the door is moving between the open and/or closed or the closed and/or opened positions. Most preferably this form of indicating means comprises flashing the open and/or closed lamp means until the door has reached the fully opened and/or closed position, whereupon the lamp means remains illuminated continuously.
