MECHANICAL DEVICE SUPPORTING THE OPENING AND CLOSING OF DOORS, PREFERABLY APPLIED TO CARS, TRAINS AIRPLANES OR YACHTS

摘要

Mechanical device (100) supporting the opening and closing of doors, preferably applied to cars, trains, airplanes or yachts, characterised in that comprising: - a first element (101), preferably jointed to an outer fixed structure, that further includes a first vertical shaft (105) that is fixed and jointed to said first element (101) and having at the lower side a first conical gear (109) that is either fixed and jointed to said first element (101); - a second element (102), connected and free to rotate in respect to the first one (101), using said first vertical shaft (105) as a hinge, said second element (102) having a first horizontal shaft (110) free to rotate on itself and being transversal in respect to said first vertical shaft (105); said first horizontal shaft (110) including, at the extremity close to the first element (101), a second conical gear (108) that is coupled mechanically to the first one (109), so that a counter-clockwise rotation of the second element (102) in respect to the first one (101) causes, through the gears (108, 109), a related clockwise rotation of said first horizontal shaft (1 10) on itself; said first horizontal shaft (110) including, at the extremity far from the first element (101), a third conical gear (113) that is coupled mechanically: at the higher side to a fourth conical gear (114), and at the lower side to a fifth conical gear (112), both placed one in front of the other on a second vertical shaft (106), that is a hinge between the second element (102) and a third element (103): with the fourth gear (114) being free to rotate in respect to the vertical shaft (106) while the fifth gear (112) being jointed to the same second vertical shaft (106); - a third element (103), connected and free to rotate in respect to the second one (102), using said second vertical shaft (106) as a hinge, said third element (103) having a second horizontal shaft (115) free to rotate on itself and being transversal in respect to said second vertical shaft (106); said second horizontal shaft (115) including, at the extremity close to the second element (102), a sixth conical gear (1 11) that is coupled mechanically at the higher side to the fourth one (1 14), so that a clockwise rotation of said first horizontal shaft (110) on itself causes, through the gears (11 1, 113, 114) a related counter-clockwise rotation of said second horizontal shaft (115) on itself, and causes at the same time a counter¬ clockwise rotation of said third element (103) in respect to the second one (102); said second horizontal shaft (115) including, at the extremity far from the second element (102), a seventh conical gear (116) that is coupled mechanically to a eighth conical gear (117) placed on a third vertical shaft (107), that is a hinge between the third element (102) and a fourth element (104); - a fourth element (104), connected and free to rotate in respect to the third one (103), using said third vertical shaft (107) as a hinge, so that a counter-clockwise rotation of said second horizontal shaft (1 15) on itself causes, through the gears (1 16, 1 17), a related clockwise rotation of said fourth element (104) in respect to the third one (103).
