摘要:
Provided is a door hinge for heavy equipment, including: first plate (100) and a second plate (200) disposed on a hinge shaft (500) of a door of heavy equipment and hinge-coupled to each other to open and close the door; and a stay unit (300) rotatably disposed on the first plate and supporting the second plate when the door is opened to prevent the door from being closed. Thus, according to the present invention, an open state of a door can be maintained by only the stay unit without mounting a bracket by overcoming the limitation that the bracket for mounting a separate door stay must be mounted to a door body in order to maintain the open state of the existing door during opening of the door.
摘要:
The device establishes a clutch connection between the sash (3;102) of a door or window and the respective frame (2:101). The device is an adjustable clutch hinge (1) with one part (5) fixed to the frame (2) and one mobile part (4) rotating about a pin (7) in a slot (8) around a clutch (9,6,6') which comprises the hinge between the two parts (4,5). Or, it is a pinzer element (E,E',E") with its upper (104,104') and lower (103,103') elements fixed to a sash (102) and holding tight between them a sliding semicircular sector (110,111,111') fixed to the frame (101), where the force of the friction is adjustable by means of the screw (107) and spring (106). The sash may be blocked in any desired position, along the entire opening amplitude, silently and with no specific manual intervention on the device (Figures 1 and 5).
