Abstract
The invention concerns a closing and opening device for doors actuated by means of a simple pressure and release operation and consists of the fact that in correspondence with the top and bottom walls in a cylinder 2, capable of rotating around its axis, three tracks have been machined for three cams 5, 6 and 7, arranged in a frontal position with respect to each other, in which a pin 8, which constitutes or is connected to door stopping means, is made to run, so that by introducing the pin through an entrance space 9, machined between cams 5 and 7, and entering as an effect of the thrust and subsequent release alternatively in contact with said cams, the cylinder is caused to rotate 180 degree and where it is envisaged, a point of stopping and locking 10 of the pin 8 in cam 5; the release position being after a further rotation by 180 degree, again in correspondence with the entrance space 9. <IMAGE>
