  • a hanger cap 46 is disposed at the operator end 47 of the shaft 41.
  • the cleaning implement 40 further includes a wringing mechanism 48, which includes a handle 49 disposed on the shaft 41 and a wringer, the wringer in the illustrated embodiment comprising a roller 50.
  • the roller 30 in the illustrated embodiment is supported by a bearing 51, which is connected to the handle 49 via a tension rod 52.
  • the wringing mechanism may include a pair of tension rods connecting the roller to the wringing handle.
  • the rods may be connected to a bearing, or the rods may terminate in bent portions, which together form a journal for the roller.
  • the universal joint 44 rests in a bowl 54 in the plate 42 to thereby permit greater angular positioning of the shaft 41 with respect to the plate 42 than would be possible absent the bowl 54.
  • the plate 42 has a shaft side 56 and a cleaning side 57 shown in Fig. 3 (but not shown in Fig.l), with a liquid absorbent cleaning member 58 disposed on the cleaning side 57 of the plate 42, as best shown in Fig. 5.
  • the plate 42 may be brought into a wringing position with respect to the shaft 41.
  • the shaft 41 is positioned within a channel 60 on the shaft side 56 of the plate 42, as best shown in Fig. 7.
  • the plate has a socket end 61 and a toe end 62 and preferably is weighted more towards the socket end 61 such that an operator may cause the plate 42 to move into the wringing position by holding the shaft 41 in a horizontal position and allowing the weight of the plate 42 to guide the plate 42 into the wringing position.
  • the universal joint 44 is mounted to the plate in a slightly off-center position to permit this weight distribution, and even more preferably the plate is constructed to have more material in the socket end 61 of the plate 42. It has been found that a weight distribution ranging from about 60:40 to about 75:25 in favor of the socket end 61 of the plate 42 is satisfactory.
  • the user may wring the mop by grasping the handle (not shown in Figs. 4 and 5) and advancing the handle toward the cleaning end 43 of the shaft 41 thereby causing the roller 50 to move into a position wherein the cleaning member 58 (best shown Fig. 5) is compressed between the roller 50 and the plate 42 to there by expel liquid from the cleaning member 58.
  • the compression is caused by forces generated in the tension rod 52, as will be apparent to one skilled in the art.
  • the force should be sufficient to cause at least some liquid to be expelled from the cleaning member 58 when the member is wet.
  • the plate 42 has a flat, unperforated cleaning side 57, although the cleaning side of plate alternatively may be provided with apertures to permit liquid to pass freely through the plate.
  • the cleaning implement 40 includes a retainer for retaining the plate in the wringing position.
  • the retainer takes the form of a dock 66.
  • the dock 66 includes a plug portion 67 (best shown in Fig. 3) which has slightly barbed portions 68, 69 (shown in Figs. 2 and 2A) for enabling a snap-fit connection with a socket 70 (shown in Figs. 5 and 6) of the plate 42.
  • Other configurations of the plug and the socket or the retainer generally are possible.
  • the dock 66 further includes at least one clip 72 (two are shown in the illustrated embodiment) for releasably retaining the roller 50 with respect to the dock 66.
  • the function of the dock 66 as retainer for the plate 42 is further illustrated in Figs. 8-13 A.
  • the plug portion 67 of the dock 66 is not engaged with the plate 42.
  • the dock 66 remains engaged with the roller 50, and thus travels with the roller 50 until the plug portion 67 fits within the socket 70 of the plate 42, as shown in Figs. 9 and 11.
  • the shaft 41 may be provided with a stop 75 (shown in Fig. 10) to limit the range of travel of the dock 66.
  • a stop 75 shown in Fig. 10
  • the dock 66 will disengage from and cease to travel with the roller 50, as shown in Figs. 12 and 13.
  • the roller 50 then may be continued to be advanced to cover the plate 42 and the cleaning member 58 (as shown for instance in Fig. 5). The advancement of the roller may be limited by the engagement of the handle with the dock.
  • the roller 50 is then retracted.
  • the dock 66 and the plate 42 can remain engaged until the roller 50 is retracted to a position wherein it engages the dock 66 by contacting the clip 72, at which point the dock travels with the roller axially as the roller is retracted.
  • the roller 50 is then retracted until the plate 42 has been disengaged from the dock 66, as shown in Fig. 13 A.
  • the dock 66 reaches the other extreme of its range of travel, and, upon further retraction of the roller 50, the roller 50 can be caused to seat within the clips 72, as shown in Fig. 8.
  • the limit of the range of travel of the roller 50 towards the operator end of the shaft preferably is defined by a slot 77 in the shaft 41, as illustrated in Fig. 14.
  • the dock 66 is provided with a pin 78, which travels in the slot and which serves to delimit the range of travel of the dock 66 and also to inhibit relative rotation of the dock and shaft.
  • the slot 77 also may delimit the range of travel of the dock towards the cleaning end of the shaft 41, thus obviating the need for the stop 75 shown in Fig. 10.
  • a handle stop 80 prevents the operator from retracting the handle 49 axially beyond the handle stop 80, thus preventing accidental damage to the dock.
  • the plate 42 preferably comprises a toe portion 81 and a major portion 82 which are hingedly connected to one another.
  • the plate 42 preferably includes several units of a set of hook-and-loop fasteners 83 for mating with a corresponding set of fasteners (not shown) provided on the cleaning member.
  • the cleaning member may be releasably attached to the plate 42.
  • the toe portion 81 is normally biased into alignment with respect to the major portion 82 via a flat spring 84, as shown in Fig.
  • the dock 66' may be provided with a treadle spring 86 (the spring 86 is shown in full in Fig. 30).
  • the spring 86 includes a locking nub 87 which fits within one of two holes 88, 89 in the shaft 41 ' (shown Fig. 22) to thereby axially retain the dock 66' relative to the shaft 41'.
  • the treadle spring 86 engages the roller 50'and biases the locking nub 87 away from the shaft, thereby permitting relative axial movement between the dock 66' and the shaft.
  • Figs. 26-29 Operation of a cleaning implement as constructed is shown in Figs. 26-29.
  • the plate 42' may be brought into the wringing position with the roller 50' engaged with dock 66' and seated in the clips 72'.
  • the dock 66' is restricted from axial movement.
  • the roller 50' advances and engages the treadle spring 86, causing the locking nub 87 to become disengaged from the operator end hole 88 in the shaft 41 ', as shown in Fig. 27.
  • the dock 66' travels with the roller 50' over a portion of the range of travel of the roller 50', as shown in Fig. 28.
  • the roller 50' no longer engages the treadle spring 86 but is still engaged by the clips 72' of the dock 66' .
  • the locking nub 87 engages the cleaning end hole 89 of the shaft 41' thus axially retaining the dock 66' with respect to the shaft 41 ' in the advanced position, whereby the plate 42' is retained relative to the shaft 41 '.
  • the slot 77' should be sized to permit axial movement of the dock relative to the shaft sufficient to allow the locking nub to engage both the operator end hole and the cleaning end hole.
  • the dock 66' includes two plugs 67' for engaging the socket 70' shown in Fig. 25, the socket retaining the plugs via a press-fit connection. The roller then may be further advanced to cause liquid to be expelled from the cleaning member.
  • the sequence of events is essentially reversed.
  • the roller 50' engages the treadle spring 86, causing the locking nub 87 to become disengaged from the cleaning end hole 89 in the shaft 41'.
  • the dock 66' will travel with the roller 50' as the roller 50', is retracted until the locking nub 87 engages the operator end hole 88.
  • the roller 50' will seat in the clips 72'
  • the shaft preferably is made of a metal such as steel or aluminum
  • the tension rod preferably is made of a spring steel

Abstract

Balai à laver comportant un dispositif d'auto-essorage. Le balai à laver comprend un manche présentant une extrémité utilisateur et une extrémité de nettoyage, une plaque située à l'extrémité de nettoyage du manche et connectée pivotante à celle-ci, et un mécanisme d'essorage. Un élément absorbant les liquides est placé sur la plaque. Le mécanisme d'essorage comprend une poignée d'essorage, située sur le manche et mobile dans le sens axial par rapport à celui-ci, et un élément d'essorage connecté à la poignée d'essorage. Lorsqu'on veut essorer le balai à laver, on déplace la poignée d'essorage par rapport à l'axe du manche de manière à déplacer l'élément d'essorage dans une position où il exerce une force sur la plaque, comprimant ainsi l'élément absorbant les liquides entre la plaque et l'élément d'essorage. Le balai à laver comprend un élément de retenue connecté au manche, qui sert à retenir libérable la plaque en position d'essorage.
