  • Another example of a mop according to this specification is a flat washable mop with a rectangular section, the edges of which are surrounded by string fringes. The rectangular section is mountable to a mop frame.
  • the person skilled in the art will be able to provide many different examples of "mops” which fit into this definition of "mop”.
  • frame assembly for a mop should therefore be understood as a frame to which a mop according to the definition specified above can be fas- tened.
  • mops are flexible implements and the frame provides a support for the mop.
  • the frame can be used in different ways. In one case, the frame is attached to one end of a handle. In another example, the frame could be attached to a cleaning robot.
  • a cleaning implement In this specification, this term refers to a complete cleaning product comprising both a mop frame and a handle. A mop will be fastenable to the mop frame of the cleaning implement.
  • mops are generally provided as essentially rectangular flexible implements made from relatively flexible materials. These mops are attached to an essentially rectangular mop frame which provides support for the mop.
  • the mop frame is usually attached to a handle which is operated by a user.
  • the mop In a typical use, the mop is dipped in water and then applied to a dirty floor or other surface. When the mop has absorbed a certain amount of dirt, the mop is rinsed in clean water. However, at a certain point, the mop has absorbed so much dirt that it can no longer be simply rinsed. The mop is then removed from the frame and a new mop is mounted on the frame. The dirty mop is then washed in a washing machine or disposed of depending on the type of mop.
  • a set of clips fastens the mop to the mop frame.
  • Examples of this type of mop are shown in JP 3631356 and DE 201 06 432 U1.

  • the clamping mechanism could be arranged such that the clamping mechanism has a variable gearing such that the speed of the clamping ele- ments in the direction towards the centre axis of the base element decreases in relation to the speed of the sliding element as the clamping elements approach a side edge of the base element.
  • the clamping mechanism comprises a linkage mechanism which comprises at least one link which is connected to the sliding element and at least one of the clamping elements.
  • the linkage mechanism could also comprise two links, a first link connected to the sliding element and the first clamping element and a second link connected to the sliding element and the second clamping element.
  • a linkage can be defined as being made up of links and joints.
  • Links can be defined as a rigid body which possesses at least two nodes which are points of attachments to other links.
  • a joint can be defined as a connection between two or more links (at their nodes), which connection allows some motion, or potential motion, between the connected links.
  • a linkage mechanism can be defined as a kinematic chain in which at least one link has been grounded, or attached to the frame of reference (which itself may be in motion).
  • a kinematic chain can be defined as an assemblage of links and joints, interconnected in a way to provide a controlled output motion in response to a supplied input motion. Linkage mechanisms are further defined in many textbooks on mechanical design.
  • the sliding element could be activated by an activation mechanism which is activated by a force being applied to the activation mechanism in a direction which has a component which is perpendicular to the plane of the base element.
  • This force is easy to apply since the mop is usually arranged on a flat surface which provides support against the force.
  • the activation mechanism could comprise a linkage mechanism comprising at least two links where a first activation link is connected to the sliding element and the second activation link is connected to the first element and the base element.
  • a linkage mechanism like this also exhibits a gearing effect.
  • the activation mechanism could also be comprised of a mechanism other than a linkage mechanism, for example a mechanism comprising toothed wheels could also be used.

  • the direction of the sliding member controls the mounting and demounting of mop 112 on frame assembly 100. Further, the direction of sliding of sliding element 108 is dependent on the direction of the force applied on activation mechanism 110. For exam- pie, force directed towards base element 102 can be applied for mounting mop 112; while a force that is directed away from base element 102 can be applied for demounting mop 112.
  • activation mechanism 110 displaces sliding element 108 to slide to the right on guide 702 when a downward force is applied on it in a direction that is perpendicular to plane of base element 102. Consequently, sliding element 108 activates clamping mechanisms 106a and 106b to extend the links of clamping mechanisms 106a and 106b about the scissor-like connection point.
  • the extension of first link 704a and second link 704b causes the clamping rods of clamping members 104a and 104b to move towards the corresponding longitudinal edges of base element 102.
  • FIG. 9 shows the mop-holding position of frame assembly 100.
  • Sliding element 108 has extended the links of clamping mechanisms 106a and 106b completely. Consequently, the clamping rods of clamping members 104a and 104b are pressed on the grooves in the corresponding longitudinal edges of base element 102.
  • This movement of clamping members 104a and 104b causes the flap of the mop to be grasped between clamping members along the longitudinal edges of base element 102 resulting in clamping of the mop.
  • the flap of mop 112 is grasped such that it is sandwiched between the clamping rods of clamping member 104a and 104b and the grooves of longitudinal edges of base element 102.
  • the speed of the clamping members 104a and 104b decreases with respect to the speed of the sliding element 108 as they approach the longitudinal edges 114a and 114b of the base element.
  • This is a form of gearing.
  • the clamping members When the clamping members are located far from the longitudinal edges, they move quite quickly with respect to the speed of the sliding member, whereas when they are close to the longitudinal edges they move quite slowly with respect to the speed of the sliding member.
  • the force transfer between the sliding member and the clamping member increases. In this way, the force applied by the clamping members to the edges of the mop when they clamping members are pulled all the way in can be quite large.

Due to the dimensions of the mop and the dimensions of the frame assembly, the clamping member 104a is arranged between the free edge of the first flap 1104a and the free edge of the third flap 1106a. Similarly, clamping member 104b is arranged between the free edge of the second flap 1104b and the free edge of the fourth flap 1106b when frame assembly 100 is placed on mop 112. After placing frame assembly 100 on mop 112, a downward force 'F' is applied by using handle 302 that causes clamping members 104a and 104b to move towards longitudinal edges 114a and 114b, respectively. As shown in FIG.
  • clamping member 104a moves towards the longitu- dinal edge of the base element, the clamping member engages the gap between first flap 1104a and third flap 1106a. Thereafter, third flap 1106a bends because of the action of clamping member 104a. Similarly, clamping member 104b engages the gap between second flap 1104b and fourth flap 1106b and causes fourth flap 1106b to bend. Clamping members 104a and 104b are then further moved towards longitudinal edges 114a and 114b. This causes third and fourth flap 1106a and 1106b to further bend toward longitudinal edges 114a and 114b. In FIG.
  • clamping members 104a and 104b are moved even closer to the longitudinal edges therefore further bending the third flap 1106a and fourth flap 1106b towards the grooves of longitudinal edges 114a and 114b, respectively.
  • This bending of third flap 1106a and fourth flap 1106b causes first flap 1104a and second flap 1104b to lift above the plane of mop 112. The first and second flaps are therefore not in contact with the fringes when the mop is properly fastened to the frame assembly.
  • clamping member 104a and 104b are moved further towards the base element 102. Consequently, third flap 1106a and fourth flap 1106b are sandwiched between clamping members 104a and 104b and grooves of longitudinal edges 114a and 114b respectively.

As can be seen from the figures, a first longitudinal side edge is longer than the second longitudinal side edge. This means that the tips of the base element are angled. This allows the mop to get into tight spaces.

  • a mop handle (not shown) is connected to the activation mechanism at the point of connection 1520 between the first plate and the second plate. By moving the connection point 1520 up or down, the sliding elements are moved in or out respectively.
  • the activation mechanism acts with a sort of gearing, whereby the speed of the sliding elements in an outwards direction decreases with respect to the speed of the connection point 1520 as the connection point moves downwards. However, the force exerted on the sliding elements is increased with respect to the input force at the connection point as the connection point moves downwards.
  • Guide elements 1522 are provided at each end of the base element.
  • the guide elements have a flange which extends above the ends of the wire as- semblies and prevents them from bending upwards.
  • a locking mechanism 1524, 1526 is provided to lock the activation mechanism in the clamping position.
  • the locking mechanism comprises a sloped tab 1524 attached to the second plate and a flexible flange 1526 attached to the base element. As the second plate pivots downwards, the sloped tab 1524 contacts the flexible flange and slowly presses it inwards. As the sloped tab is forced even further downwards, the sloped tab passes the flexible flange and the flexible flange springs out thereby locking the sloped tab underneath the flexible flange.
  • the current embodiment has the advantage of being relatively simple and light weight. In addition, there are few components and many of the components could be made from plastic. It should also be mentioned that in the current embodiment, the clamping members are shown as integrated with the wire assemblies. However, it could also be imagined that the clamping members were made from a separate material and were connected to a wire assembly. It should be obvious to the person skilled in the art that other embodiments which are based on the current embodiment could also be provided.
  • a cleaning implement that includes a frame assembly for holding a mop.
  • the frame assembly includes a mechanism that is simple to operate for mounting and demounting the mop. Further, the frame assembly can be easily attached with a robotic cleaning arm.
