Definitions

  • the field of the present invention relates to an adjustable pressure wringer for floor mops.
  • the cloth must retain a certain amount of water.
  • the degree of moisture achievable varies according to the maximum force that can be exerted when wringing and will depend on the texture and thickness of the mop.
  • Said wringers are generally operated by a grip, at the end of which there is a handle for manual gripping; said handle rotates a shaft on which arms are fixed, whose ends are hinged to connecting rods that push a surface in a rectilinear manner. Said mop to be wrung is placed between said surface and a support wall.
  • the maximum kinematic efficiency which corresponds to maximum effectiveness, is achieved when the arms and the relative connecting rods align with each other.
  • the thrust surface reaches a predetermined distance from the counter wall within which the mop to be wrung is placed.
  • the object of the present invention is to make available a pressure mop wringer with an adjustable wringing residual space that overcomes one or more of the above disadvantages.
  • a further object of the present invention is to make available a pressure mop wringer that allows you to obtain an adjustable wringing residual space without any additional and/or external parts.
  • Another object of the present invention is to make available a pressure mop wringer that allows you to obtain an adjustable wringing residual space with several fixed positions.
  • An important object of the present invention is to make available a pressure mop wringer that allows you to obtain an adjustable wringing residual space without the need for tools, and which can be easily implemented by the operator.
  • Another important object of the present invention is to make available a pressure mop wringer that allows you to obtain an adjustable wringing residual space with a limited series of interventions for a multiplicity of positions.
  • each of said seats on the side walls has a circular configuration and each rotating pawl is always permanently joined to the seats on the side walls with a single possibility of rotating, and has a circular external configuration to connect with each circular seat on the walls of the frame, and on the inside an internal seat to connect with each end of the shaft, characterised by the fact that the axis of the circular external configuration is parallel to and distant from the axis of said internal seat.
  • each of said seats on the side walls has a hollow configuration in a direction corresponding to the direction of movement of the pressure surface and said rotating pawl, where it is able to permanently move, after a rotation, its internal seat near to or away from the two ends of said hollow.
  • said wringer comprises a spacer that has a surface corresponding to the pressure surface and that approaches said second larger pressure surface side and is connected with it in two or more rotated positions, corresponding to each of which is a fastening at a position some distance from said pressure surface.
  • said two or more spaced apart positions are a multiple and/or sub-multiple of the amount of movement of the shaft ends within said seats of said pawl, making a modular composition for approaching/moving away from the pressure surface to the support surface.
  • a wringer 1 of the pressure wringer variety 2 is shown moving with a translational movement.
  • Said wringer 1 comprises a frame 3 basically formed by a quadrilateral with at least the upper side 4 open at the top so that the mop to be wrung can be inserted inside the wringer.
  • the side walls 5, 6 are opposite each other and adjacent to the upper side 4, and are joined at the front by a wall that generally corresponds to the support wall 7.
  • Said shaft 10 is rotated by a handle 11, at the free end of which there is a grip 12 for the operator.
  • One or more arms 13 are fixed on said shaft 10, at the ends of which a first end of one or more connecting rods 14 is hinged, the second end of the one or more connecting rods 14 is hinged on the translational pressure surface with respect to the frame 3, which corresponds to the wringing surface 2
  • the kinematic chain from the handle 11 to the pressure surface 2 allows the rotational movement of the handle 11 to be transformed into a rectilinear movement of the pressure surface 2.
  • the mop to be wringed is inserted within the space between the pressure surface 2 and the support wall 7, and in this space the mop is compressed when the handle 11 is operated.
  • the minimum distance between the pressure surface 2 and the support wall 7 is reached when the alignment of the three hinging axes occurs: shaft-arm, arm-rod, connecting rod-surface-pressure, and which generally coincides with an alignment between arm and connecting rod, and on this occasion there is maximum pressure.
  • the shaft 10 is shifted by moving it closer to and away from the pressure surface 2 with a movement of the rotation seat that modifies its position.
  • the rotation seat 8, 9 on the side walls is a circular seat and is keyed by a pawl 11 with an externally circular configuration 12 that can rotate in two stable positions.
  • the internal seat 17 of the pawl 15, within which the rotation shaft 10 is housed, has an axis parallel to and spaced apart from the axis of the circular seat.
  • the seats are configured as a groove extending in the direction of the movement of the pressure surface 2, therefore the shaft 10 can move from one end of said groove to the other and held at these ends by a pawl that in this case assumes the configuration of a seat of the shaft 10 that is connected with the side wall in different and spaced apart positions.
  • a spacer 18 to be connected to the pressure wall 2.
  • Said spacer can be connected with the pressure wall 2 with various joints, for example by rotating it by 90° or 180° degrees, and for each rotation the spacer 18 joins the rear pressure surface 2 protruding at a different distance.
  • the modular composition of the movement of the shaft 10 with the variable protrusion of the spacer 18, allows you to obtain an adjustment of the minimum width between the pressure surface 2 and the support wall 7 for a more effective wringing of the mop.
