Definitions
- the invention relates to a self-wringing mop, with a handle, an actuating sleeve arranged rotatably on the handle, a mop head with cleaning elements which can be wrung out by a relative rotation between the handle and the actuating sleeve, and with a backstop for fixing the strokes on the handle when wringing out against unwanted Turning back, comprising rib-like elevations extending in the axial direction at least over a predetermined limited length section of the handle and at least one locking member protruding radially inward from the actuating sleeve into the rotational region of the rib-like elevations, which locking element by the rib-like elevations upon rotation of the handle in the blocking direction Wall of the actuating sleeve is pressed and thus forms a stop for the rib-like elevations, on the other hand, when rotating in the forward direction, the rib-like elevations evade outwards against a spring force.
- a self-wringing mop which consists of a handle, an axially displaceable and rotatable sleeve arranged on the handle and a mop head with cord-like cleaning elements, with their lower ends at the lower end of the handle and with their upper ends are attached to the lower end of the actuating sleeve.
- the cleaning elements can be brought upward into a wringing position by moving the actuating sleeve from a lower wiping position, in which they sag downward in a loop and in which the actuating sleeve can be freely rotated, in which they can be stretched and wrung out by rotating the actuating sleeve.
- the known self-wringing mop has a pawl device.
- This consists of a ring arranged on the handle, from which spring elements protrude radially outwards.
- the actuating sleeve is accordingly provided with ribs in the upper area on its inner circumference. To wring out, the actuating sleeve is pulled up from the lower wiping position up to the ring with the spring elements and rotated in the wringing direction.
- the spring elements and the ribs are arranged and designed so that rotation in the wringing direction is possible, but is blocked in the opposite direction.
- US Pat. No. 6,212,728 B1 provides a similar solution, in which a self-wringing mop of the generic type is described. Like the one described above, this has a handle, an actuating sleeve and a mop head with cord-like cleaning elements, which are fastened to both the handle and the actuating sleeve, and a backstop.
- the backstop consists of a locking member that projects radially inward from the actuating sleeve into the through opening of the actuating sleeve and engages in a corresponding rib structure on the handle. When rotating in the wringing direction, the locking member dodges the rib-like elevations arranged on the handle against a spring force to the outside.
- the locking member When rotating in the opposite direction, the locking member is supported on the sleeve wall and thus forms a stop for the rib-like elevations on the handle. The rotation is blocked.
- the rib structure is provided on the handle only over a limited length section, so that the lock can be released again by pushing down the actuating sleeve.
- the wringing process itself corresponds to that described above. Even with this self-wringing mop, the components of the backstop must be made very precisely, as with the mop described above, which increases the manufacturing costs and the manufacturing effort. Presentation of the invention
- the object of the invention is to develop a cleaning device of the generic type in such a way that the backstop is easier and cheaper to manufacture and in particular as few components as possible are required.
- This object is achieved with a self-wringing mop with all the features of claim 1 and a backstop with all the features of claim 14.
- Advantageous embodiments of the invention are described in the subclaims.
- the handle has a polygonal elevations extending in the axial direction at least over a predetermined limited length section of the handle and at least one locking member protruding radially inward from the actuating sleeve into the rotating region of the rib-like elevations, which on rotation of the handle in the blocking direction by the rib-like elevations the wall of the actuating sleeve is pressed and thus forms a stop for the rib-like elevations, on the other hand, when rotating in the forward direction, the rib-like elevations against a spring force toward the outside So, the handle has a polygonal elevations extending in the axial direction at least over a predetermined limited length section of the handle and at least one locking member protruding radially inward from the actuating sleeve into the rotating region of the rib-like elevations, which on rotation of the handle in the blocking direction by the rib-like elevations the wall of the actuating sleeve is pressed and thus forms a stop for the
- the self-wringing mop according to the invention is characterized by a simple and inexpensive construction.
- a handle with a cross-section that is polygonal at least over a limited length no additional components are required, in particular no additional rings with a groove-like or rib-like structure. Since the locking member is simply pushed outwards by the edges of the rotating handle, no complicated shaping of the same is required. In particular, a form fit is not necessary.
- the self-wringing mop according to the invention does not have any sharp-edged, outwardly projecting components which could pose a risk of injury.
- the actuating sleeve is advantageously axially displaceable on the handle and the handle has at least one length section in which the actuating sleeve can be freely rotated in both directions.
- the backstop can be released by simply shifting the actuating sleeve in the axial direction onto this length section or can be actuated by shifting onto the upper polygonal length section of the handle.
- the length range in which the actuating sleeve is freely rotatable is arranged at the lower end of the handle.
- a self-wringing mop is brought into the wiping position by pushing down the actuating sleeve, so that with the self-wringing mop according to the invention, the wiping position can be set and the reversing lock can be released with one hand.
- the production outlay for a self-wringing mop according to the invention is reduced in particular by the fact that the handle is divided into exactly two length sections, namely an upper length section with a polygonal cross section and a lower length section in which the actuating sleeve can be freely rotated.
- the easiest way to freely rotate the actuating sleeve is to have the handle in the corresponding area have a cross-sectional diameter that is smaller than the inner diameter of the actuating sleeve with locking members.
- the handle has a round cross section in this area.
- a handle with a polygonal, upper length section and a round, lower length section can be manufactured in one piece, in particular if it is made of steel, as is generally customary, for example by means of a roll-forming process in which the initially round-shaped handle alternately forms a polygonal cross section becomes.
- the arrangement according to the invention can in particular be applied to a self-wringing mop in which the cleaning elements comprise elongated yarns, threads or cords or the like, which are detachably fastened with their lower ends to the lower end of the handle and with their upper ends to the lower end of the actuating sleeve, so that by moving the actuating sleeve from a lower cleaning position, in which they sag downward in a loop and in which the actuating sleeve can be freely rotated in both directions, they can be brought up into the area of the backstop to an upper wringing position, in which the cleaning elements can be moved through Turn the actuation sleeve are wrung out.
- the cleaning elements comprise elongated yarns, threads or cords or the like, which are detachably fastened with their lower ends to the lower end of the handle and with their upper ends to the lower end of the actuating sleeve, so that by moving the actuating slee
- the handle is preferably made of steel
- the actuating sleeve is made of plastic, in particular polypropylene (PP)
- the locking element arrangement is also made of plastic, in particular polyoxymethylene (POM).
- the handle has proven to be advantageous for the handle to have an octagonal cross-section in the area of the backstop, since the octagonal cross-section also offers sufficiently large support surfaces for the locking member or the locking members in the usual diameters of a handle of approximately 18-24 mm the octagonal cross section is a sufficient number of rib-like elevations for this diameter range, so that rotation in the opposite direction is prevented even in the case of large restoring forces in cooperation with a corresponding number of locking members.
- locking elements can be freely selected to suit the respective application.
- a locking element may be sufficient for low restoring forces.
- several locking members at least two, preferably four, are used.
- the locking member has the shape of a vertically arranged plate which can be inserted into a corresponding slot-shaped receptacle at the upper end of the actuating sleeve.
- the ring with the plate-shaped locking members can be inserted in a simple manner from above into corresponding gap-shaped openings in the actuating sleeve.
- an O-ring made of elastic material is used in a simple manner as the resetting spring, which is inserted into a groove running in a ring on the outer circumference of the actuating sleeve and the locking members.
- the locking member and the edge-like elevations it is not necessary for the locking member and the edge-like elevations to form a positive connection on the polygonal length section of the handle. This gives a high degree of freedom of design.
- the locking member only has to have a first contact surface for the edge-like elevations for displacement outwards when rotating in the forward direction, and a second contact surface which, when rotating in the opposite direction, applies the force exerted on the locking member by the edge-like elevation of the polygonal length section of the handle guides the inner wall of the actuating sleeve.
- This can be achieved in a simple manner, for example, in the case of a locking member which is displaceable tangentially to the outside, in that the plate-shaped locking member has a groove on its rear side, as seen in the direction of rotation.
- the backstop described above in connection with the self-wringing mop can not only be used for one, but generally for any system consisting of a rod-shaped element and a sleeve rotatably arranged on the rod-shaped element, which prevents rotation in one of the two possible directions shall be.
- Such a backstop includes a rod-shaped element with at least a limited length section extending in the axial direction rib-like elevations and at least one locking member projecting radially inward from the sleeve into the rotational region of the rib-like elevations, which is pressed by the rib-like elevations against the sleeve wall when the rod-shaped element rotates in the blocking direction and thus forms a stop for the rib-like elevations, when rotating in the forward direction, on the other hand, the rib-like elevations evade outward against a spring force, the rod-shaped element in the limited length section having a polygonal cross section and the rib-like elevations being formed by the edges of this length section extending in the axial direction.
- the locking member is preferably arranged to be displaceable outward tangentially in accordance with the direction of movement of the peripheral edges
