WIPO Patent Application WO/2011/024322
Kind Code:
A1
Abstract:
A pole tool for lifting a working tool up to a high position, which principally comprises a long, adjustable-length pole for a handle where a plurality of pipe members are arranged to be drawn out and inserted or to be shaken out, is provided, on the upper end side of the pole for a handle, with a spindle pin to which the upper end side of a traction string is hooked, a fitting holder that receives the pole for a handle and is provided in the side surface with an elongated hole for passing the spindle pin, the holding holder of an operating section for stopping the spindle pin, and an appropriate working tool having a mechanism into which is attached an elongation spring for spring supporting the holding holder of the operating section so as to be able to elevate or lower. The pole tool for lifting a working tool is further provided, closely to the lower end of a lower stage pole, with the pulling operation tool of the traction string for coupling at the upper end side thereof with the spindle pin of the working tool in order to lift the working tool up to a high position by means of the pole for a handle and to operate the working tool by the pulling operation of the traction string. The pole tool for lifting an working tool is also provided with the pulling operation tool of the traction string which is held by a worker with one hand and is slid downward while resisting against the elongation spring attached in the mechanism of the working tool or which is fitted to the pole for a handle on the axis near the lower end thereof so that the operation tool can be slid upward by means of the spring. Two winding pins are planted at an interval in the vertical direction on the side surface of the pulling operation tool, and the traction string of an appropriate length is stretched between and passed around the winding pins so that the string can be fed out or wound according to adjustment of the length of the pole for a handle.
