Abstract
A floor mop has two carrier plates (5) that are connected with a common carrier center piece (3) in jointed manner and carry an absorbent mop covering (6). A mop handle (1) is affixed on the carrier center piece (3) by way of a cardan joint (2), in jointed manner. A wringer slide (9) that can be moved along the mop handle (1) and is guided not to rotate has two rigid wringer arms (11), the ends (11a) of which can each be brought into engagement with a guide surface (17) on the back of the carrier plate (5) assigned to them, in each instance, by way of rollers (12).

A floor mop comprising:
- two carrier plates connected to a common carrier center piece in jointed manner and which carry an absorbent mop covering, a mop handle affixed on the carrier center piece, and a wringer slide which is movable along the mop handle, the wringer slide having two rigid wringer arms, each of which is movably engagable with a back of one of the two carrier plates, wherein the mop handle (1) is connected with the carrier center piece (3) by way of a cardan joint (2), and ends (11a) of the wringer arms (11) can each be brought into engagement with a guide surface (17) on the back of the carrier plate (5) assigned to them, in each instance, and the wringer slide (9) is guided on the mop handle (1) so that it cannot rotate, wherein the arms move into and out of engagement with the carrier plates, and the ends of the arms are configured with roller elements such that each of the roller elements contacts the back of one of the two carrier plates and each of the roller elements may independently be disengaged from the back of the carrier plate while another of the roller elements is engaged on the back of the carrier plate.
A floor mop comprising:
- two carrier plates connected to a common carrier center piece in jointed manner and which carry an absorbent mop covering, a mop handle affixed on the carrier center piece, and a wringer slide which is movable along the mop handle, the wringer slide having two rigid wringer arms, each of which is movably engagable with a back of one of the two carrier plates, wherein the mop handle (1) is connected with the carrier center piece (3) by way of a cardan joint (2), and ends (11a) of the wringer arms (11) can each be brought into engagement with a guide surface (17) on the back of the carrier plate (5) assigned to them, in each instance, and the wringer slide (9) is guided on the mop handle (1) so that it cannot rotate, wherein the end (11a) of each wringer arm (11) carries a rotating roller element (12, 15, 20), and wherein the roller element is a wheel (20) provided with recesses (19) on its circumference, which engages with at least one projection (21, 22) on the back of the carrier plate (5).
A floor mop comprising:
- two carrier plates connected to a common carrier center piece in jointed manner and which carry an absorbent mop covering, a mop handle affixed on the carrier center piece, and a wringer slide which is movable along the mop handle, the wringer slide having two rigid wringer arms, each of which is movably engagable with a back of one of the two carrier plates, wherein the mop handle (1) is connected with the carrier center piece (3) by way of a cardan joint (2), and ends (11a) of the wringer arms (11) can each be brought into direct contact with a guide surface (17) on the back of the carrier plate (5) assigned to them, in each instance, and the wringer slide (9) is guided on the mop handle (1) so that it cannot rotate;
- wherein the end (11a) of each wringer arm (11) has a pressure surface (16) with a convex curvature, wherein the arms move into and out of engagement with the carrier plates, and the ends of the arms are configured with roller elements such that each of the roller elements contacts the back of one of the two carrier plates and each of the roller elements may independently be disengaged from the back of the carrier plate while another of the roller elements is engaged on the back of the carrier plate.
