Abstract

PURPOSE:To facilitate the closing operation of a cabin door of a construction machinery and enhance the safety of an operator. CONSTITUTION:An auxiliary door handle 18 is installed on the inside surface of a door 17 hinged to a cabin 14. Also one end part 18a of the auxiliary door handle 18 is pivoted to the locking part 19 of the door 17 through pins 20, and a coiled spring 21 is installed on the pins 20 to energize the other end part 18b of the auxiliary door handle 18 so as to make in contact with the inner surface of the door 17. Then a stopper 22 is installed near the pins 20. When the auxiliary door handle 18 is held and pulled, it is rotated around the pins 20, and one end part 18a of the auxiliary door handle 18 is made in contact with the stopper 22. When it is merely pulled, a rotational force is given to the door 17 to rotate it around hinges 16 and to close a lifting port 15 by the door 17.

[Problems to be Solved by the Invention] Conventional cabin 1 described above
Is very inconvenient because the operator has to stand up from the cockpit and lean out to operate when the door 4 is fully opened when the stay 6 is gripped and the door 4 is closed. At the same time, there was a risk of falling. Thus, it is conceivable to extend the length of the stay 6 in order to facilitate the grasping by the operator, but since the stay 6 projects from the inner surface of the door 4, when the door 4 is closed. As a result, the stay 6 may come into contact with the operator, hindering the operability and damaging the operator.

According to the present invention, when the door in the fully opened state is closed, the door auxiliary handle disposed inside the door is grasped and pulled so that one end of the door auxiliary handle is pulled. The door auxiliary handle rotates forward with the pivotally attached pin as the center of rotation. Further, if the door auxiliary handle is pulled while being gripped, the door auxiliary handle comes into contact with a stopper arranged near the pin. And
When the door auxiliary handle is pulled while being in contact with the stopper, a rotational force is applied to the cabin door via the door auxiliary handle, and the door is rotated around the hinge as a rotation center to be closed. To do. Thus, after the door is closed and the grip of the door auxiliary handle is released, the bias of the torsion coil spring causes the door auxiliary handle to rotate about the pin as the center of rotation, and The other end comes into contact with the inner surface of the door and returns to the original state.
