Abstract
A device and a method for opening a pivotable façade element both for everyday comfort ventilation purposes and for emergency opening in the case of e.g. fire. The device comprises a rigid frame part pivotable about a centre of rotation displaced from the centre of rotation of the pivotable façade element. The rigid frame part is moved by an actuator providing a lifting force to a contact surface of the façade element, thereby pivoting the façade element. The device also comprises a shock absorber. A release mechanism and a method of releasing a façade element is also disclosed.

1-18. (canceled)
A device (2) for opening a pivotable façade element (1) comprising
- a rigid frame part (6) having a proximal and a distal end said frame part having a first side (4) with a proximal and a distal end and a second side (5) with a proximal and a distal end, said proximal end of the second side being joined to or integral with the first side (4) at a substantially right angle thereto,
- an actuator (10) pivotally connected to an inner frame part (14) of the façade element (1) and pivotally connected to the distal end of said first side (4) of the rigid frame part (6) whereby the actuator force engages the inner frame part (14) of the façade element (1) and said rigid frame part substantially at the proximal end of the rigid frame part (6), and
- wherein the rigid frame part (6) is pivotally connected to the inner frame part (14) of the façade element (1) at the proximal end of the first side (4) of said rigid frame part (6), and
- the distal end of the rigid frame part (6) abuts a contact surface (16) of the pivotable façade element (1).
