Definitions

  • This invention relates to trolley-mounted squeezers for mops and the like.
  • a squeezing device (referred to herein as a "squeezer") into which the head of the implement can be inserted.
  • squeezing devices are often mounted on a mobile trolley together with other items of cleaning equipment.
  • GB 2 314 501 A discloses a trolley-mounted squeezer which is operated by hand using a lever arm.
  • US-A-4 707 877 discloses a trolley-mounted squeezer which is operated by a foot pedal via a pair of operating levers.
  • the present invention seeks to provide a trolley-mounted squeezer which is patentably different from any known form of squeezer.
  • the present invention proposes a trolley-mounted squeezer as set forth in the appended Claims.
  • the cleaning trolley 100 is of a known type comprising an inverted-U shaped upright frame 101 which is upstanding from the open rear end of a horizontal U-shaped base frame 102.
  • the base frame is mounted on castor wheels 103 so that the trolley can be used to carry cleaning equipment and materials (not shown) from place to place.
  • a squeezer 104 is mounted at hand level at the front of the upright frame 101 for operation by a treadle 105 mounted at the front of the base frame 102.
  • the squeezer includes a moulded plastics shell 1 which incorporates a substantially rectangular and generally horizontal squeezing surface 2 containing an array of holes 3 through which water can pass into a bucket or like receptacle in use.
  • the surface 2 extends between upright hollow end walls 4 and 5, within which is rotatably journalled a pivot bar 6, extending above the rear of the squeezing surface 2.
  • a pair of radial arms 8 and 9 are secured at spaced positions along the bar 6 to extend above the surface 2.
  • the arms 8 and 9 carry respective squeezing heads 10 and 11, each comprising a substantially rectangular and flat plate 12 having a pair of lugs 13 and 14 upstanding from its top surface.
  • the heads 10 and 11 are pivotally secured to the respective arms 8 and 9 for limited freedom of movement by pivot pins 16 inserted through the lugs 13 and 14 and the free ends of the arms.
  • pivot pins 16 inserted through the lugs 13 and 14 and the free ends of the arms.
  • the mechanism for rotating the bar 6 is shown in Fig. 4, in which the mechanism adopts a position in which the squeezing heads are raised.
  • the mechanism is enclosed within the end wall 5 which is formed with a plastics cover 20 (Fig. 3) secured by screws inserted into pillars 21 (not all labelled).
  • the end wall contains a pair of spaced reaction plates 22 through which the pivot bar 6 is inserted, the plates being non-rotatably located within the end wall by a stub shaft 23.
  • a lever arm 24 is secured to the bar 6 between the plates 22, and a tension spring 25 acts between the arm 24 and a pin 26 fixed with one of the plates 22 so as to rotate the bar in a direction which moves the squeezing heads 10 and 11 away from the surface 2.
  • a pivoted V-plate member 27 comprising a pair of angularly disposed arms 28 and 29 is secured between the plates 22 on a pivot pin 30.
  • the lower of the two arms 29 is pivotally secured to an operating linkage 31 which extends downwards through the bottom of the end wall 5.
  • the linkage 31 is connected for operation by the treadle 105 as will be described below. If desired, a choice of pivot positions may be provided on the arm 29 to allow adjustment of the treadle travel and operating pressure required.
  • the upper arm 28 is pivotally secured by pin 32 to a link 33 which, in turn is pivotally secured by pin 34 to the lever arm 24.
  • the link 33 comprises a pair of parallel plates disposed on opposite sides of the arms 24 and 28 to avoid twisting of the pins 32 and 34.
  • the pivoted V-plate 27 and arm 24 could similarly comprise two or more superimposed plates.
  • the permitted range of pivotal movement of the V-plate 27 is determined by a pin 35 secured to the plates 22 which travels in an arcuate slot 36 in the V-plate 27.
  • the treadle 105 comprises a treadle bar 40 (see Fig. 1 also) which extends substantially the full width of the trolley, the treadle bar being shown in this fully depressed condition.
  • the treadle bar 40 is provided with a pair of rearwardly extending arms 41 which are secured to a transverse pivot bar 42.
  • the base frame 102 includes a pair of bottom members 43 which are mounted beneath the side members of the frame by standoff arms 44 and 45, to extend in a front-rear direction.
  • the pivot bar 42 is journalled in bearings at the front ends of the bottom members 43 whereas a further pivot bar 46 is similarly journalled in bearings at the rear ends of the bottom members, the axes of the pivot bars 42 and 46 being substantially parallel.
  • the treadle 105 is operably connected to the rear pivot bar 46 by a link 48.
  • the front end of the link 48 is pivotally secured to a lever arm 49 which is upstanding from the front pivot bar 42, whereas the rear end of the link is pivoted to a lever arm 50 which extends downwardly from the rear pivot bar 46.
  • the application of foot pressure to produce downward pivotal movement of the treadle 105 thus results in an opposite clockwise pivotal movement of the rear pivot bar 46, which, in turn, causes a further lever arm 52, extending rearwardly from the bar 46, to move downwardly.
  • the lower end of the operating linkage 31 is pivotally secured to this arm 52 so that the linkage 31 also moves downwardly to apply a squeezing force to the heads 10 and 11 as described above.
  • the mechanism described results in an efficient squeezing operation, maximising the transfer of foot pressure to the squeezing heads when they are close to the squeezing surface 2 but, at the same time, producing a controlled spring-assisted return of the treadle.
  • the arrangement of the operating pivots, levers and linkages also minimises the risk of interference to the squeezing operation by articles normally carried on the trolley.
