SAFETY DEVICE IN LIFTING LEG
Document Type and Number:
Japanese Patent JPH08268240
Kind Code:
A
Abstract:

PURPOSE: To improve the extent of safety in manual operation by installing a locking mechanism, locking a hand-operating gear at a nonengagement position with a reduction gear of this hand-operating gear, and making a switch be turned to ON at the locking position, in a lifting leg which makes an up leg inner cycliner move up and down by the rotation of a screw shaft.

CONSTITUTION: To be selected to lifting operation by means of manual operation from a drive motor, first of all, a locking mechanism 37 is lowered, releasing its engagedness If so, a limit switch 41 is turned to OFF, whereby automatic operation by the motor cannot be cue any linger. In this state, a manual handle shaft 31 is shifted in the axial direction and a hand-operating gear 35 is engaged with a gear wheel 19 or 24, and a handle 32 is manually operated, whereby a gear shaft 9 is rotated via a gear system, and thus manual operation of a lifting leg to be installed at the right is promoted. On the other hand, if the handle shaft 31 is set up in an intermediate position and a locking mechanism 37 is moved upward, the switch 41 is turned to OB, so the drive motor of the lifting leg is made into a state of being operated.
