• the present invention relates to an electric door opener according to the preamble of claim 1.
• Such an electric door opener has a locking element, which is formed in two parts and consists of a locking lever and a cascade, which have a different distance to the respective associated electromagnet, so that when energizing the electromagnets acting on the adjustment forces of locking lever and Add cascade.
• the prior art discloses electric door openers that are equipped with electromagnets that are energized to release a door latch. By energizing the electromagnets, a locking element is magnetically attracted by the electromagnet. The stroke travel of the locking element to be covered in this case overcomes a distance which prevails between the electromagnet and a locking lever in the non-energized state of the electromagnets.
• the prior art involves the disadvantage that the magnetic force of the electromagnets decreases sharply with increasing distance between the locking element and the electromagnet. As a result, a small magnetic force is available at the moment of current supply to the electromagnets, the operating point, but a considerably larger magnetic force is required in order to move the locking element into a release position.
• the invention includes the technical teaching that the locking element is formed in two parts and consists of a locking lever and a cascade, which have a different distance from the respectively associated electromagnet, so that when energizing the electromagnets acting on the adjustment forces of Add locking lever and cascade.
• the inventive embodiment has the advantage that in the locked state of the adjustment angle, the cascade can be positioned closer to the electromagnet associated with the cascade, since unlike the locking lever, it does not block or release the adjustment angle, but is mounted so as to be relatively freely rotatable on an axis.
• the locking lever has to maintain a predetermined by the present in the door opener lever ratios distance to the associated electromagnet, which can be ignored by the cascade.
• the electromagnet is the operating point where the largest magnetic force is needed to move the locking lever to a release position.
• the added forces of locking lever and cascade acting on the adjustment angle ensure an increased magnetic force at the work point.
• the distance of the cascade to the electromagnet is less than the distance of the locking lever to the electromagnet.
• the cascade is freely rotatably arranged on the axis of rotation. Due to the freely rotatable arrangement of the cascade, the cascade is independent of the prevailing lever ratios and independent of possible preloads that can act on the electric door opener. Thereby, the cascade can be positioned with a small distance to the associated electromagnet. It is also advantageous that the cascade has a driver which cooperates with current supply of the electromagnet with the locking lever while the locking lever at least partially entrains the electromagnet. This ensures that the distance between the locking lever and the associated electromagnet is reduced, whereby an increased magnetic force acts on the locking lever, which is used at the operating point.
• a further preferred embodiment is that the locking lever and the cascade each have a separate solenoid is assigned.
• differentiating electromagnets can be used. It is also advantageous that when energizing the electromagnets, the distance between the locking lever surface of the locking lever and the locking lever associated electromagnet due to the driver of the cascade is reduced. Thus, the required magnetic forces are available directly at the operating point.
• the distance between the locking lever surface and the electromagnet is greater than the distance between the cascade surface and the electromagnet.
• the locking lever is imposed by the present in the door opener housing leverage a predetermined distance that can ignore the cascade, whereby the cascade can be positioned with a smaller distance to the associated electromagnet.
• the locking lever and the cascade are rotatably mounted on a rotation axis within the door opener housing.
• a simple arrangement is ensured in conjunction with the required leverage ratios within the door opener housing.
• the locking lever with the rotary axis pin and the cascade with the rotary axis pin are rotatably mounted on the axis of rotation of the Matöffnergephinu- ses. As a result, a simple construction of the locking lever and the cascade is possible.
• the locking lever is spring-loaded disposed within the door opener housing. In the de-energized state of the electromagnets, the locking lever is moved due to the spring load in the blocking position, in which the locking lever blocks the adjustment. It is advantageous that the receptacle for receiving the return spring is arranged in a portion of the locking lever surface of the locking lever. The return spring is to be installed in a simple and reliable way. It is also advantageous that the locking lever has a hook in a gate. Thus, a simple construction of the locking lever and a required hook for blocking the adjustment angle is guaranteed.
• an advantageous embodiment is that the hook blocks or releases the adjustment angle.
• the pivoting movement which exerts the locking lever when energized and when withdrawing the energization of the electromagnets, the adjustment of the hook is blocked or released.
• the driver of the cascade is arranged on the side opposite the cascade surface.
• the driver is given space to overcome a distance between the cascade and the locking lever can.
• the driver is in operative connection with the locking lever in a portion of the plant surface.
• the locking lever In the de-energized state of the electromagnets, the locking lever is moved due to the spring force of the return spring in the blocking position in which the locking lever blocks the adjustment.
• the driver contributes to the spring force of the return spring being transmitted to the cascade, whereby the cascade is forcibly moved into the position in which the cascade is at a distance from the associated electromagnet, this distance being smaller is, as the distance between the locking lever and the electromagnet associated with the locking lever.
