FIELD: construction. ^ SUBSTANCE: parallel opening hinged joint, comprising the first guide, the second guide and at least two pairs of hingedly joined crossing connecting links. At the same time each pair of crossing connecting links is attached to the guides with the help of a fixed axis and a movable axis in each guide. At the same time the connecting element connects two movable axes in the guide so that movable axes move simultaneously. At the same time the connecting element is installed and moves inside the guide. ^ EFFECT: development of a hinged joint that ensures smooth opening of ventlights, including ventlights with considerable weight, excluding the potential skew. ^ 7 cl |
