Shoulder-Belt-Traction Hand-Push Tool

Abstract

A traction tension bar of a pipe member is connected to an end of a handle of the hand-push tool. A tension bar ring metal member of a ring-shaped metal member is disposed at an end of the tension bar extending backward. A shoulder belt is connected through a shock absorption spring to the tension bar ring metal member by an attachment hook, and can be fitted around the body of the user. The user fits the shoulder belt around the body, holds the handle of the hand-push tool with both hands, leans forward and puts their weight into the shoulder belt to produce traction, and starts to walk while putting their weight into the shoulder belt to pull the hand-push tool.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a shoulder-belt-traction hand-push tool.[0003]2. Description of the Related Art[0004]Conventionally, many hand-push tools have been invented. For example, highly efficient snow removal tools and snow removal accessories are disclosed (for example, see Patent Document 1). Also disclosed are scoop type snow shovels (for example, see Patent Document 2) with which a series of snow removal operations such as for pushing and separating snow, pushing out snow, collecting snow and scooping and disposing of snow can be performed in an integrated manner; they help reduce the labor of removing snow and streamline snow removal operations and lessen the labor of removing snow. The following hand-push tools are also disclosed: mop handle attaching devices (for example, see Patent Document 3) that effectively use force exerted by a user and prevent the mop from falling down; water removal floor wipers ...

AI Technical Summary

Benefits of technology

[0048]The shoulder-belt-traction hand-push tool makes it possible to reduce labor involved in a hand-push operation and frees the user from an uncomfortable posture because the shoulder-belt-traction hand-push tool is pulled through a tension bar by a shoulder belt fitted around the body of a user. Thus, it effectively reduces the labor and

Problems solved by technology

However, there was a problem that when the user performs hand-push operations while walking with the snow removal tool and the snow shovel according to Patent Document 1 and 2, resistance caused by snow places a heavy load on both hands of the user.

Moreover, the user needs to lean forward because the user exerts force with both hands.

Thus, a heavy burden is imposed on the back of the user, and this may cause pain in the back.

Also, there was a problem that when a user performs hand-push operations for a prolonged period with the cleaning mop of Patent Document 3 and the water removal wiper of Patent Document 4, resistance load placed on both hands of the user becomes heavier with time, so the user needs to lean forward in the hand-push operation, and thus a heavy burden is imposed on the back of the user.

This causes the user to become extremely fatigued.

Further, there was a problem that the
