Abstract

PROBLEM TO BE SOLVED: To solve such a problem that in a conventional one-handed cleaning implement with a handle, force which an operator applies is hard to be effectively transmitted due to a structural factor in a surface which grinds, soil does not easily come off and the load is applied to an operator's wrist too much.SOLUTION: The cleaning implement with the handle includes an annular or a half-annular arm support part 3d which is equipped with elasticity at one end of the handle 3c as shown in the drawing 3, and the structure is made to be able to grasp the handle 3c while putting the arm through the arm support part 3d. By this structure, a contact point of the arm support part 3d and the arm serves as a fulcrum, and force of the arm and applied weight are effectively transmitted to a friction part 3a by the principle of leverage.

Description

  This invention relates to the cleaning tool of the form used especially with one hand in the cleaning tool with a handle.

  Patterned cleaning tools are widely used for cleaning water tanks such as bathtubs, window glass and floors. In order to clean a place that is difficult to reach in an easy posture, a pattern is attached to a rubbing material such as a brush or a sponge, and a detergent or the like is attached and the rubbing is performed.

  If you can use both hands with a long-handled cleaning tool such as for flooring, it is easy to scrape heavy dirt with weight. However, in the case of a cleaning tool with a handle that is rubbed with one hand, such as for a bathtub, it is difficult to apply force and a considerable fatigue burden may be applied to the wrist. The difference can be explained mechanically. FIG. 1 shows a simplified mechanical structure of a long handle cleaning tool for a floor. By holding the fulcrum 1b firmly with one hand and pressing the force point 1a with weight with the other hand, it is possible to apply a strong pressure to the action point 1c. On the other hand, FIG. 2 schematically shows the mechanical structure of a handle-type cleaning tool that is rubbed with one hand, such as for a bathtub. It is necessary to grip and push the index finger of the power point 2a strongly. However, since the distance between the force point 2a and the fulcrum 2b is extremely short relative to the distance between the action point 2c and the fulcrum 2b, the force is hardly transmitted effectively, and a strong load is applied to the wrist.

  In the case of a conventional cleaning tool with a handle for one hand, the force applied by the operator is difficult to effectively transmit to the surface to be rubbed due to its structural factors, and it is difficult to remove dirt, and there is a problem that the operator's wrist is overloaded. . The object of the present invention is for one hand with a structure that can be easily cleaned even by workers with weak grip and wrist strength, such as children, women and elderly people, using the lever structure of a cleaning tool with a handle for both hands as a hint. It is to provide a cleaning tool with a handle.

  In the cleaning tool with a handle of the present invention, as shown in FIG. 3, an annular or semi-annular arm support portion 3d having bending elasticity such as resin or metal material is provided at one end of the handle 3c, and the handle is passed through the arm support portion 3d through the arm. The structure is such that 3c can be gripped. With this structure, the contact point between the arm support portion 3d and the arm serves as a fulcrum, and the force of the arm and the applied weight are effectively transmitted to the rubbing portion 3a via the connecting portion 3b according to the principle of the lever.

  FIG. 4 simply shows the mechanical structure of the bathtub cleaning as an example. The distance between the force point 4a and the fulcrum 4b is relatively greater than that of a conventional one-handed handle-type cleaning tool. It becomes possible to take. By imparting elasticity to the arm support portion 3d (FIG. 3), the load applied to the operator's arm is dispersed by bending, and the adhesion between the action point 4b and the wiping surface can be enhanced.

  As shown in FIG. 3, the present invention has a structure in which the handle 3 c is gripped by passing the arm through the arm support portion 3 d, and therefore the angle between the arm and the handle is limited. Therefore, it is desirable that the connecting portion 3b is movably connected so that the rubbing portion 3a faces the wiping surface. As this connection method, for example, there is a prior art (Japanese Patent No. 3143618).

  In addition to the form of gripping the handle as it is as shown in FIG. 6, the gripping method of the handle corresponds to the surface to be cleaned having various angles such as a bathtub, for example, or the protruding grip 5a of FIG. A shape such as the rod-shaped grip 7a is suitable for the posture of the operator.

  In FIG. 3, the arm support part 3d has an annular shape made of a material having bending elasticity. This form is not limited to an annular shape, but may be a semi-annular shape as shown in FIG. Further, the elastic feature does not necessarily have to be provided only by the arm support portion, and may be provided by the entire handle.
