Definitions

• the present invention relates to a broom-brush for cleaning the bottom and the side walls of a pool.
• the bros are constituted by a longitudinal rigid support on the surface of which bros bristles are applied, and over which adapts the end of a handle, generally telescopic.
• the longitudinal ends of the bracket bros are slightly raised relative to the plane of the central part of the support.
• This type of brush has the following drawbacks.
• the front portion of the support is raised and the ends of the brush hairs are removed from the bottom wall of the pool to be brushed, when pushing the handle forward. Reverse tilting occurs when the handle is pulled.
• front and rear refer to the direction of advancement of the bros se when it is located in front of said handle on which it exerts a thrust.
• the object of the present invention is to provide a new brush for bottom pool brush, which provides a solution to the problem mentioned above and more generally to provide a brush which has a greater stability and a better contact. the brush with the bottom wall of the pool when you manipulate and use the broom handled from the upper end of the handle by a person located high on the edge of the pool.
• the present invention provides a brush for cleaning the bottom and side walls of a pool comprising a longitudinal rigid support on the surface of which brush bristles are applied and over which the end of a handle, preferably telescopic, whose axis YY 'coincides with the rectilinear part of said longitudinal support, characterized in that said rigid support has at its longitudinal ends a curved profile, with a curvature extending forward of said support to a longitudinal end and a curvature extending rearwardly of said support at the opposite longitudinal end.
• the curved returns at the ends of the rectilinear longitudinal portion of the brush support give width to the brush support and stabilize it by preventing it from rotating in rotation about an axis perpendicular to the axis of the handle and parallel to the longitudinal axis XX 'of said support, which promotes the maintenance of the ends of the brush against the brush wall ser.

• This inclination feature of the handle attenuates or even eliminates the phenomenon of leverage generated by the pulse of the handle against the support.
• This displacement and the inclination of the handle facilitate the good positioning of the brush against the bottom wall to be brushed, the horizontal component of the force resulting from the thrust of the handle against the bottom wall, increases as the angle of inclination of the handle increases with respect to the vertical or that the angle the inclination of the handle decreases relative to the surface of the bottom wall, which is the case when the person handling the upper end of the handle pushes with the brush in front of him in the direction of the thrust.
