Title:
AUTOMATIC REGULATING DEVICE FOR HANDLE HEIGHT OF WALKING TYPE WORKING MACHINE
Document Type and Number:
Japanese Patent JPS6322774
Kind Code:
A
Abstract:
PURPOSE:To keep the height of a handle from a ground approximately at a specified value, by method wherein an inclination gauge, detecting the inclination angle in the longitudinal direction of a machine body, and a setter, arbitrarily pointing an inclination angle, are provided, and when there is a difference between outputs from the two instruments, a signal is outputted to a driven source to move a handle. CONSTITUTION:Since, during running on a road, an inclination angle of a handle stand 5 is alpha1, an inclination gauge 15 measure the inclination angle. In this case, a setter, capable of arbitrarily setting the initial inclination angle of the handle stand 5 by means of a dial, is provided, and outputs from both the inclination gauge 15 and the setter are compared with each other by means of a comparing circuit. The two signals are compared with each other and computed, and if there is difference therebetween, i.e. when it is decided that a handle 6 must be vertically moved individually from the handle stand 5 for interpolation, its amount and a direction are fed to a drive source through an output circuit. In which case, the drive source rotates a handle shaft to set a height H1 of the handle 6 from a ground. This constitution enables the height H1 of the handle from a ground to be kept at a specified value in any working state.
